SQUATTING TOILET SEAT TO FACILITATE SMOOTH DEFECATION AND URINATION

Abstract

A safe; effective squatting toilet seat has multiple embodiments to simulate the natural mode of bowel and urine evacuation in the squatting position practiced for centuries before modern sitting toilet was introduced. This inventive design bends the thigh at hip, which pushes back the pubic bone and tilts the pelvis forwards that bends the torso resulting in relaxation of the puborectalis and pubourethralis muscle noose at anorectal junction while straightening the rectum to come in alignment with the anus for fast easy and fast bowl evacuation. This invention also provides a separate insertable squatting toilet seat placed on the top of the existing toilet seat on the toilet bowl. It is provided with urinal embodiment to prevent urine spilling and to induce easy flow of urine in females due to relaxation of pubo-rectalis-urethralis muscle. Embodiments include toilet bowl sterilization by germicidal visible violet-blue spectrum light, toilet deodorizer, and seat warmer.

Description

FIELD OF THE INVENTION

The invention relates to squatting toilet seat (STS) to facilitate bowel movements and urination by relaxing puborectalis and pubourethralis muscles of the pelvic floor without causing an obstruction/impediment in the flow of excreta due to positioning of the seat during toilet use. Such a change in squatting on the toilet seat provided by this invention changes the angle of the anus, rectum and urethra from an acute angle to an obtuse angle by assuming a squatting posture, which allows easy and smooth defecation and urination. It is intended to be used by all the population using the western style sitting flat toilet seat, especially individuals who suffer from constipation, hemorrhoids, urinary incontinence and various anal, rectal, bladder and urethral afflictions.

BACKGROUND OF THE INVENTION

A flush toilet is a common bowl that people sit on to evacuate waste liquid or solid liquid and is generally used in most lavatories all over the world. A flush toilet has a toilet seat enabling a user to sit on a bowl thereof so that a user evacuates while sitting on the toilet seat. The toilet seat is rotatably coupled to the toilet for men to easily urinate after lifting the toilet seat, if necessary. The problem is that current toilet seats are on a flat plane, when a user defecates while sitting on the toilet seat, the angle between the user's back and thighs is a right angle or at least 70 degrees or more. When a user defecates in this posture, the portion between the rectum and the anus is bent, so the rectal content movement is interfered with, and a person may have to assume val salva method of breath holding to increase the abdominal pressure against this anorectal angle which can create many afflictions. Accordingly, when a person uses the flush toilets of the related art, defecation is not easy, so the user has to exert a larger force and, in some instances, takes a longer time to defecate. Therefore, since people repeatedly defecate in a sitting posture with a right angle on flush toilets for a long period of time, in serious cases, it can cause constipation, hemorrhoids, irritable bowel syndrome, cancers, and other colorectal diseases.

The positions assumed during bowel movement varies from culture to culture. In Western civilization, most people sit on a toilet seat with the knee and hip bent at ±90° angle to torso to perform a bowel movement, whereas the Asians, especially in India, squat of a toilet in sitting position as shown in the figure (FIG. 17). Medical data shows that evacuating the bowel contents in in squatting position is associated with less anorectal afflictions, with least trauma to the anorectal junction and anus with reduced constipation. This position eliminates and/or reduces the anorectal angle (FIGS. 6,17,) and make the descent of the excreta from the rectum to anus easy without straining. On the other hand, the posture required to sit on a typical western civilization toilet creates a kink in the colon at anorectal junction that hinders the free flow of bowel contents, making it difficult to complete a bowel movement. This can lead to many health issues like constipation, hemorrhoids, fistula, fissures, infections and other anorectal afflictions as well cancer of the anal canal due to trauma caused by pushing the hard stools against the delicate mucosa year after years.

Mālāsana (literally sitting down pose of yogic asana), also known as the yoga squat, is a yogic asana. This asana is a squat with heels flat on the floor and hip-width apart (or slightly wider if necessary), toes pointing out on a diagonal. The torso is brought forward between the thighs, elbows are braced against the inside of the knees, and the hands press together in front of the chest in Añjali Mudrā (“Garland Pose”. Yoga Journal. Retrieved 12 Jun. 2009). There is increased incidence of knee osteoarthritis among squatters who squat for hours a day for many years [Liu C M, Xu L (2007). “Retrospective study of squatting with prevalence of knee osteoarthritis”]. There is evidence that sustained squatting may cause bilateral peroneal nerve palsy. A common name for this affliction is squatter's palsy although there may be reasons other than squatting for this to occur (Macpherson J M, Gordon A J (1983). “Squatter's palsy” British Medical Journal Kumaki D J. “The facts of Kathmandu: squatter's palsy”. Journal of the American Medical Association 2 Jan. 1987; 257(1): 28. To{hacek over (g)}rol, E. (2000). “Bilateral peroneal nerve palsy induced by prolonged squatting”. Military Medicine. 165 (3): 240-2. Spinks, Rosie (9 Nov. 2017). “The forgotten art of squatting is a revelation for bodies ruined by sitting”. Quartz (publication). Retrieved 14 Nov. 2017. “5 Bathroom Mistakes That Can Lead To Pelvic Floor Dysfunction”. HuffPost Canadian version. 21 Jul. 2016. Retrieved 21 Feb. 2019. Hovering Over the Toilet). For societies who rarely squat when using a toilet, squatting as a different posture may bring health benefits. For this reason, we introduce the toilet seat that facilitates the posture of the squatting position which can be used daily.

Modern (Western) method of sitting on a toilet seat used by millions of people results in the knee and hip at a 90-degree angle bent with the anal opening directed to the posterior-center of the toilet waste disposal bowl. On the other hand, in squatting (Eastern) method without the rest of the body not resting on the toilet seat with knee and hip bent acutely and drawn close to the torso, also known as squatting eastern toilet style. Squatting for defecation has an effect on the anatomy of the anorectal angle which allows easy passage of undigested food and urine from the rectum and the bladder compared to the western style of defecation in a sitting position due to anatomical changes related to these two types of defecation which brings about a change in the angle between the anus and rectum by puborectalis and pubourethralis muscles.

The anorectal angle, which is the angle formed in the colon where the puborectalis muscle wraps around the rectum (FIGS. 1, 2, 3, 9-11) and anus junction; is a very important factor in maintaining continence—the ability to retain a bodily discharge voluntarily to hold the waste till the time to evacuate (moderation, self-control and restraint). On the other hand, the term incontinence is used to describe lack of voluntary control over urination or defecation. Puborectalis and pubourethralis muscles, which are the inner part of the vast pelvic floor muscle (Levator ani) that creates the anorectal angle which plays an important role in continence and incontinence related to defection and urination.

Many people from around the world used to perform the natural squatting position for defecation and urination used and still in use in many parts of the world especially in Asian countries. Constipation, hemorrhoids, intestinal cancer, or Crohn's disease were unfamiliar to them. However, modern technology introduced the sitting toilet seat on the toilet bowls and has not been designed and engineered for the body to be in a squatting position for defecation and urine flow. Sitting on westem-style toilets create a position that makes the process more difficult due the change in the angling of the out-flow excreta disposal body tracts. The body is meant to be in a squatting position for defecation as well for urination but sitting on a western-style toilet creates a position that makes the process more difficult which results in self-induced afflictions and the latest studies have shown evidence that the sitting position during defecation is associated with a number of health issues.

Modern sitting toilets can cause a multitude of diseases. According to a study published in an Israeli magazine called “Journal of Medical Sciences”, the sitting position while emptying your intestines is the principal cause of diseases such as: hemorrhoids, intestinal inflammations, colon cancer, pelvic diseases, Crohn's disease and may result in an incomplete emptying of the bladder resulting in retention and its associated urinary tract infection leading to urinary incontinence.

Scientistic research shows that “The frequency of intestinal diseases (hemorrhoids, constipation, appendix inflammation, polyps, ulcerative colitis, irritable bowel syndrome) is similar in South African white males and in the populations of rich Western countries. In the rural areas of Africa, with a traditional lifestyle, these diseases are very rare or almost unfamiliar.

One affliction that is blamed on the use of modern toilets is the contribution towards the development of constipation and hemorrhoids and even urine retention with associated urinary tract infections. To induce the squatting position, we want to change the seat of the toilet bowl, so that squatting and tilting of the pelvis with relaxation of puborectalis and puborectalis muscle takes place whose contraction predisposes to constipation, hemorrhoids, urinary retention; at the same time enjoy the use of the toilet. It is an easy fix that all people can add to an existing toilet which is used every day.

Sitting position during defecation is blamed for hemorrhoids and some degree of constipation, maybe even urinary retention. Hemorrhoids develop due to dilatation of veins located in the lower part of the rectum and the anus, i.e., anorectal junction. They develop as a result of straining during defecation particularly in people who have a harder stool in defecating in the sitting position on the toilet with a taught puborectalis muscle, which leads to weaker and a slower defecation which requires greater straining. Additionally, an abundance of heart attacks and strokes are caused by straining during defecation in a sitting position, thus the need for our inventive device. On the other hand, emptying the intestines and urinary bladder while squatting is much faster and simpler, and you almost don't need any straining unless one has developed hardened stools or an obstruction to the urethra.

Toilet use in the sitting position allows tightening of the puborectalis and pubourethralis muscles of the pelvic floor which may prevent a total defecation—complete emptying of the rectum and bladder of undigested food and urine that can accumulate. The content that remains in the intestines and urine can be a good foundation for infection development and can cause inflammation and even cancer. Crohn's syndrome belongs to the group of irritable bowel diseases (IBD)—inflammatory disease. Inflammatory autoimmune disease of the intestines, in which the immunological composition of the organism attacks the person's own digestive system due to changes in the bowel movement that adds to the affliction.

With this evidence, and the development of this inventive squatting toilet seat device to induce the squatting position for emptying the bladder as well. Women urinate much easier when in a squatting position versus a sitting position due to the relaxation of pubourethralis-vaginalis fibers of the pelvic floor muscle—namely levator ani (FIGS. 1-1a, b). In the sitting position on the toilet, the bladder may not be completely emptied so it allows holding of the urine and leaves a culture media for bacterial growth and development which can further lead to infections of the urinary tract from urethra to bladder and to urethra and pelvis of the kidney.

The act of performing defection and urination in a squatting position relieves the pressure of the pelvis. This allows the urinary bladder to empty easily without retention, as well as the contents from the uterus during a women's monthly menstrual cycle. Sitting position on the other hand, lack natural anatomical relief and “pressing”, and a part of the menstrual liquid remains inside the uterus. A longer blood retention duration can lead to development of a great number of bacteria like Staphylococcus aureus, which can result in toxic shock syndrome (TSS).

Squatting posture is a natural way which allows an easy and smooth defecation and urination with complete emptying of the bowel and the bladder. It's not very comfortable to use the squatting position without being seated due to body weight on the legs. Using our Squatting Toilet Seat (STS), produces this natural squatting positions, by using our STS, a person sits with knees and hips sharply bent and the buttocks close to the opening of the toilet bowl with some pelvis tilt, which helps in opening the path for defecation due to proper alignment of the rectum and anal canal colon and anal opening.

In Japan, squat toilets represent an essential part of every bathroom, particularly in the elder population. Apart from health and hygienic benefits which the squatting position offers, Japanese people simply love it because it “saves them time”.

The two most common defecation positions of flush toilets designed for use:

• • 1. a sitting position popular in Europe and North and South America with a toilet seat, with additional considerations for those with disabilities, or
  • 2. a squatting posture more popular in Asia (see squat toilet seat) that does not use toilet seating located on the toilet bowl.

Urine incontinence describes any accidental or involuntary loss of urine (wee) from the bladder—known as urinary incontinence and feces (poo) or flatus (wind) from the bowel—known as fecal and urine incontinence. Incontinence can range in severity from a small leak to complete loss of bladder or bowel control.

Fecal incontinence (poor bowel control) is more common than people think. The tone of the puborectalis muscle plays an important role whether the person is continent or incontinent. Incontinence does not discriminate—it affects women, men and children of all ages, physical ability and background. There are however some health conditions and life events that can put you at an increased risk of developing either urinary or fecal incontinence. We want to use the incontinence process temporarily during defecation to empty the rectal undigested food completely by using our inventive Squatting Toilet Seat.

The sitting posture common to western-style toilets causes and/or maintains a narrowing of the anorectal angle (FIG. 16) and prevents the puborectalis muscle from relaxing, which may cause impediment in complete emptying the bowels with ease. The posture required to sit on a typical western civilization toilet creates a kink in the ano-rectal junction that hinders the flow of bowel movements, making it difficult to complete a bowel movement as well as urine flow. This can lead to many health issues like constipation, hemorrhoids, and other anorectal afflictions including urine retention with urinary tracts afflictions.

Additionally, the sitting position may cause the person to repeat the Valsalva maneuver, i.e., exhalation against a closed airway (inter-glottic area) to increase internal torso pressure, holding one's breath to increase internal pressure, which can lead to syncope in asthenic people. A sitting posture may increase issues related to weakness in the colon wall because of the increased straining needed to defecate. No one has reported the adverse effects of Valsalva on the brain cerebrospinal fluid, venous drainage, G-lymphatics, Virchow-Robin space and its CSF content, and paravascular space around the brain vascular system. Can it cause rupture of blood vessels, herniation of CNS structures, muscae Volans production of the eye during straining? We did report the presence of arachnoid villi in optic nerve of man and monkey which drains cerebrospinal fluid from the optic nerve during straining during defecation or otherwise (Shantha T R and Bourne G H: Arachnoid villi in the optic nerve of man and monkey. Expt Eye Res 3:31-35 (1964). Before this discovery was made, no experts on the eye knew how the optic nerve CSF pressure is released during coughing, bearing, lifting weight, straining, asthma attacks etc. which could create temporary blindness during these conditions.

The Eastern method of the squatting position during defecation, besides releasing the tension in the puborectalis muscle (it does not relax the puborectalis muscle as claimed by many step stool promotors because it reduces the tone or tension of the muscle), there is a tilt created by the pelvic cavity, reducing the angle between the sigmoid colon and rectum and rectum and anus, which facilitates the smooth movement of collected undigested food to move with ease to the anal opening. This fact is ignored by all promoters of the step stools offered in the marketplace.

Our Squatting Toilet Seat (STS) invention is based on relaxation of the puborectalis and pubourethralis muscles of the main pelvic floor muscle levator ani. The pelvic floor is a system of muscles, ligaments, tissue and nerves arranged at the bottom of the pelvis that form a hammock, supporting their bladder and uterus as well as rectum and control the anu and urethra below the pelvic floor. In women, their pelvic floor and its muscles and ligaments undergoes many anatomical and physiological changes, especially during pregnancy, childbirth and menopause. Natural and C-section childbirth are capable of increasing your chances of developing urinary incontinence after having children. Kegel exercises can strengthen one's pelvic floor muscles, which can help prevent and manage incontinence, and even make sex more pleasurable. Use of our Squatting Toilet Seat can also help to alleviate and delay the symptoms of these conditions. Functions of levator ani muscle along with pubourethralis and pubovaginalis muscles (FIG. 1,1a, 1b), as floor of the pelvic cavity, have important roles to play in the correct functioning of the pelvic and abdominal viscera. The roles of the pelvic floor muscles are:

• • a) Support of abdominopelvic viscera (bladder, urethra, intestines, rectum, anus, prostate, uterus and such) through their tonic contraction. Puborectalis muscle is constantly under tonic contraction to control the defecation and urination.
  • b) Levator ani offer resistance to increases in intra-pelvic/abdominal pressure during activities such as coughing, defecation, or lifting heavy objects and such to control the exit of urine and rectal contents-defecation and urination.
  • c) Levator ani muscle play an important role in urinary and fecal continence. The muscle fibers have a sphincter like action on the rectum and urethra to control their evacuation by voluntarily to great extent. The connective tissue they surround also play a role. They relax to allow urination and defecation and it is facilitated by use of Squatting Toilet Seat.

Dorsal to the rectum and anal junction is the ventral part of the sacrococcygeal muscle (which can be considered a part of levator ani pelvic floor muscle) and laterally the rectum is mainly bordered by the levator ani muscle. Ventrally it is bordered by the vagina and urethra in the female and by the urethra in the male and Squatting Toilet Seat will facilitate the opening of these orifices and expelling the contents of the rectum, bladder through urethra, as well as uterus blood through cervix and vaginal opening.

The pubovaginalis and pubourethralis muscles (FIGS. 1, 1a 1b) are the muscle fibers of the levator ani which act as voluntary control of the vaginal urethral outlets. The control of pubourethralis in female is very important in controlling the stress incontinence. Using our Squatting Toilet Seat not only reduces the angling of the anorectal junction, it also reduces the angling for easy urine flow especially using our Squatting Toilet Seat complete emptying of bladder and thus reduces the residual urine in the bladder and rapid bladder filling with residual urine that results in frequent stress incontinence if bladder is not emptied completely.

Using our Squatting Toilet Seat of our invention not only has an effect on the puborectalis muscle, it also has an effect on the pubourethralis muscle which is involved in continence of urine especially in females. By using our Squatting Toilet Seat, there will be less residual urine in the bladder after urination, hence less nerve reflex action to evacuate the bladder, with complete emptying of the bladder reducing the stress incontinence in female.

Now there are many kinds of toilet foot stools in the market for the same purpose. Many of the advantages of the squatting position may be obtained when using western-style toilets (i.e., where the bowl is raised from the ground and is intended for sitting as opposed to squatting) in conjunction with a footrest stool and such devices or telephone books or bricks to raise the foot of the leg. Footrests help raise the legs bent at the hip and knee toward the chest and help to lessen the normal sitting angle of about ninety-degrees to much more. As the feet are raised, the puborectalis muscle relaxes, the colon aligns with rectum and anus, allowing gravity to aid evacuation, and the required expulsive effort by valve salve method lessens the angle and force the puborectalis muscle to open.

There are some that also have an ability to increase or decrease the height of foot stool to increase or decrease the anorectal angle and make the user more comfortable. As such, several footrests exist in the art that are aimed at allowing a human to achieve a better anorectal angle while sitting on a toilet simulating, to some extent the eastern style of squatting. However, people come in a variety of sizes, heights and shapes. Taller people need a different height of footrest than shorter people to achieve the desired anorectal angle to facilitate the bowel movement without straining excessively. Further, many people need to adjust the height or angle of the toilet footrest due to certain medical restrictions or conditions that may inhibit their ability to fully squat. Children may also require different heights than adults. As such, there remains a need for a toilet solution that is easily adjustable to different heights and angles so as to accommodate users of all sizes and medical needs. The present invention described herein seeks to solve these and other problems of step stools.

There are many patents on step stools, and still patents were issued to Edwards and Naik as described below with similar function of lifting legs up acting as step stool in front of the base of the toilet. U.S. Ser. No. 10/064,497B2 to Edward et al. describes an adjustable toilet footrest assembly that has a main footrest and a height-adjusting accessory. They claim that this device completely relaxes puborectalis muscle to allow easy passage of rectal contents during bowel movement. Of course, this position does not completely relax it as claimed by the inventors, but the muscle loses tone and some tightness and thus reduces the angle it creates for bowel movement with less straining during the process. The height needs to be adjusted with an extra height extender, and thus occupies floor space when not in use and does not allow provision easy urine evacuation and drainage. As such, there remains a need for a toilet footrest that is easily adjustable to different heights and angles so as to accommodate users of all sizes and medical needs.

U.S. Ser. No. 10/588,471B2 to Naik et al. describes many types of step stools, including a collapsible stool providing a raised heel squat position to a user that engages the stool. The inventor claims that the raised heel squatting position promotes a healthy and productive experience on a toilet. There is no medical proof for such a claim.

United States Patent Application 20180325337 to KIM, Seong Gyu, describes a flush toilet capable of correcting a defecation posture, in which a seat disposed on a toilet main body for a user to sit is inclined on the top thereof such that the front where the user's thighs are placed is higher than the rear where the user's hips are placed. Accordingly, smooth defecation is allowed by preventing bending between the intestine and the anus in the body by correcting the posture of a user into a squatting posture such that an angle between the upper body and thighs of the user is maintained between 35-50° as if the user were using a squat toilet. Therefore, defecation time is reduced, and the user's legs are prevented from becoming numb, thereby improving satisfaction with defecation. Further, intestinal movement is activated during defecation, so smooth defecation is possible, and constipation, hemorrhoids, irritable bowel syndrome, cancers, and other colorectal diseases are prevented. This system is complicated, and has to replace the entire toilet, which is expensive and not practical, hence our simple, inexpensive and practical Squatting Toilet Seat, is easy to use by all age groups on the existing toilet, with no need for a plumber to install.

U.S. Pat. No. 4,578,829 to Lenosky, describes a toilet seat is disposed in an elevated position relative to the bowl of a conventional toilet. The toilet seat has a plurality of clamps disposed around its underside. Each of the clamps engages the toilet bowl, whereby the toilet seat is securely maintained in the elevated position so as to be an aid for invalids and others who experience difficulty in using a conventional toilet seat. It is not practical to use.

U.S. Pat. No. 5,666,673 to Ammatelli, describes a toilet seat structure having a support framework for placement atop a conventional toilet bowl. A cradle assembly presents a pair of triangularly-shaped side panels which pivotally and tangentially engage laterally spaced-apart rails extending along each side of the toilet bowl. Spanning the side panels are a front lift bar and a conventional toilet seat. User induced pressure on the lift bar positions the lift bar at the front of the bowl with the seat being presented at an angled position to allow user entry. Downward pressure on the seat causes the toilet seat to assume a functional horizontal position above the toilet bowl. Concurrently, the lift bar swings upwardly so as to draw the legs of the seated user towards the user's torso. At this position the user is in an enhanced “squatting” position which is said to be effective for bowel movements. Alternative embodiments of the cradle assembly, associated rails, side arms and support framework are shown. The positions of the lift bar and the toilet seat at its horizontal position are adjustable to allow the structure to be adapted for use by various users. It is too complex to be adopted and used on a toilet bowl.

U.S. Pat. No. D876597 to Luper describes a toilet tilted for facilitating bowel movement.

U.S. Pat. No. 5,524,295 to Ford, describes a child's toilet seat adapter that permits use of a standard adult toilet by children comprises a unitized structure including a flat seat member having a central opening therein and a handgrip adjacent each side edge thereof, together with a footrest extending downwardly and forwardly from a front edge of the seat member, the seat member having a pair of attachment flanges, each of which is formed to extend downwardly and inwardly from a side edge of the seat member, the attachment flanges adapted to slide over and retain opposite side edges of the seat of the standard adult toilet.

U.S. Pat. No. 5,311,617 to Ammatelli, describes a toilet device for raising the legs of a user relative to the trunk of the user as an extension body having a lower end adapted to engage with a rim of a bowl of the toilet, and a peripheral wall extending upwardly from said lower end and defining a passage there through for waste; as a physiologic toilet seat attachment for placing the user in the proper crouched configuration for bowel movements. It is cumbersome, difficult to manufacture and clean.

Many users are too busy to adjust the height of the many of foot stop devices, thus may not be used all the time for all the people of different heights. Hence our invention that does not need a height adjustment and can be used by all without using restricted bathroom space and does need adjustment.

Everyone has to go to the toilet once a day and as many as 3 times a day to defecate and more than 5-7 times for urination. It is estimated that about 1 in 6 Americans experience chronic constipation. That is almost 18 million people in US and about 420 million all over the word. The western diet and method of emptying bowel in the sitting position is blamed on various anorectal afflictions. In southeast Asia and many African countries who squat to evacuate the bowel may not face the same serious health problems due to the angle created by the muscle and loss of tension in puborectalis muscle due to its relaxation.

The above foot stools do not play any role in the urination experience as this invention describes. Existing foot stools do not improve the experience of an unstrained bowel movement and urination. Generally, stools have a flat design which requires the entire foot to be lifted to the top of the stool, which may not be comfortable for those having bodily difficulties, such as elderly people, people that are not that flexible, people with joint pains and such.

Defecography may be indicated for the following evaluation of rectal outlet obstruction (obstructed defecation) symptoms and evaluation of all types of rectal (fecal) constipation and incontinence such as Anismus (pelvic floor dyssynergia), rectocele, enterocele, signmoidocele, rectal prolapse, descending perinium syndrome, fecal incontinence needed. It is the intent of the present invention to reduce these conditions developing and/or progressing.

The introduction of our inventive toilet seat, which is not a foot lifting stool/foot rest/or a tilted toilet bowl), automatically provides flexing position at the hip and at the knee; bent close to the torso, that relaxes the puborectalis muscle to facilitate easy passage of stool, and provides all the advantages of eastern style emptying the bowels with sitting on the western or eastern toilet bowl Squatting Toilet Seat helps you to get into a natural toilet posture, but not the extreme squatting position, allowing your rectum to optimally eliminate body waste comfortably, quickly, and easily.

DETAILED DESCRIPTION OF THE INVENTION

It is known that a squatting position by a user of a toilet promotes a healthy easy, smooth, fast, bowel movement. Attempting a bowel movement in a sitting posture with a current western-style toilet seat used in millions of homes all over the world, can create a kink in a user's anorectal junction (FIGS. 9, 16) that hinders a smooth, fast and easy bowel movement. An upright sitting position used on the toilet during defecation as it is case in millions of western homes, can also lead to many health issues, including but not limited to constipation, hemorrhoids, anal fissures, anal fistula and such. Thus, while a western toilet offers the comfort, sitting on a typical toilet is not conducive to a productive and healthy smooth, bowel movement.

A Squatting Toilet Seat of this invention allows a user to squat on the toilet seat inclined to lift the thighs to induce an angle between the upper body (torso) and thighs of the user is maintained between 35-50° instead of 70-90° in a traditional toilet. A rounded portion of this invention is curved from the hips to the back at the rear portion of the seat. The rear end of the rounded portion is lower than or at the same level as a front end of the inclined seat. The seat is detachably disposed on the top of the toilet main body and hinged to the rear of the top of the toilet main body to be placed on or lifted from the top of the toilet main body.

The Squatting Toilet Seat of our invention is capable of correcting a defecation and urination posture and may further include many embodiments detailed in the figures. This Squatting Toilet Seat of the flush toilet may further include a feet rest unit disposed under the toilet main body to protrude forward to support the user's feet and handrails for the comfort of users with comorbidities while sitting and getting up from our Squatting Toilet Seat.

In the following detailed description of the invention described briefly above, reference is made to the drawings in which reference numerals refer to like elements, and which are intended to show by way of illustration specific embodiments in which the invention described herein. It is understood that other embodiments may be utilized and that structural changes may be made without departing from the scope and spirit of this invention. Although the instant invention has been described in relation to particular embodiments thereof, many other variations and modifications and other uses will become apparent to those skilled in the art.

FIGS. 1, broad sheet of pelvic floor levator ani muscle 100 and its part the puborectalis, pubovaginalis and pubourethralis muscles. FIG. 1 shows the pelvic floor muscles (levator ani) that surrounds the urethra 68 as pubourethralis and vagina 69 as pubovaginalis 46, and rectum 44 as puborectalis 56. Puborectalis and its components arise from the posterior surface of the pubic symphysis bones 45 of the pelvis which also contribute muscle fibers to form with pubourethralis around the urethra 68 and pubo vaginalis encircling the vagina 69. Puborectalis muscle 56 as part of the pelvic floor is also formed by the contribution from pubococcygeus and iliococcygeus 57, ischiococcygeus 58 (coccygeus) muscles component of levator ani muscle which form the pelvic floor. Though puborectalis 56 plays a major role in defecation and control of bowel movement, both voluntary and involuntary, the pubococcygeus 56 which is located just adjacent to puborectalis muscle 46 also plays some role in controlling defecation. Further, lifting the thigh using our Squatting Toilet Seat and bending forwards the torso forwards during defecation plays and important role in straitening the rectum by tilting the pelvis so that the anus and rectum are aligned for easy and fast evacuations of rectal contents due to relaxation of pelvic floor muscles, though the puborectalis muscle 56 plays a major role in easy fast evacuation of the rectal contents.

FIG. 1A is the drawing of 100a showing the pubo-vaginalis 46 and pubo-urethralis 46a muscle fibers derived from the levator ani, and it is view of this muscle from below. The diagram shows how closely the puborectalis muscle 56 contributed to pubourethralis 46a, 68 and vaginalis muscles 69 to control the urine flow and menstrual blood. Using our Squatting Toilet Seat will relax these muscles derived from the puborectalis muscle 56 which is also relaxed for easy flow of urine, in addition, easy flow of menstrual blood in female during periods. The rest of the explanation is same as FIG. 1.

FIG. 1B is the drawing of 100b showing the pubo-urethralis 46a muscle fibers derived from the levator ani 56, and it is view of this muscle from below. The diagram shows how closely the puborectalis muscle 56 contributed to pubourethralis 46a, to control the urine flow. Using our Squatting Toilet Seat will relax these muscles derived from the puborectalis muscle 56 which is also relaxed for easy flow of urine thus prevents the residual urine in the bladder, thus reducing the urge to urinate. The rest of the explanation is same as FIG. 1. FIG. 2 shows the drawing of 200 displaying the puborectalis muscle 46 arising from the pubic symphysis bones 45, curls backwards to encircle the rectum, creating anorectal angle 51 and its effect on holding the rectal 44 contents due to the acute angle 51 it creates (long connecting arrow) to hold the undigested food in the rectum at the anorectal junction sling without incontinence. It also shows the angling of the rectum 44 and anus surrounded by anal sphincters 47 with anal opening 48 which runs downwards and backward during sitting position or standing position or during lying down surrounded by anal sphincters 47. Defecation is both voluntary and involuntary, and the voluntary control of holding the recital content can be voluntarily controlled of your own free will or accord due to anal sphincters 47.

FIG. 3 shows the drawings of 300 displaying the sitting position used in the traditional toilet seat 60 covering the toilet bowl 84, used for defecation and urination in millions of homes. Note the angle between the thighs, knees and as well as anorectal angle 51 is about 90° in this method of traditional toilet use. The puborectalis muscle 46 arising from the pubic symphysis bones 45, curls backwards to encircle the rectum at anorectal junction, creating anorectal sling and its effect on holding the rectal 44 contents due to the acute angle 51 it creates to hold the undigested food at the anorectal junction in the rectum. It also shows the angling of the rectum 44 and anus 47 which runs downwards anus slightly backwards to open at anal opening 48 to the exterior, during sitting position or standing position or during lying down surrounded by anal sphincters 47, at the anal opening 48. Defecation and urination is both voluntary and involuntary, and the voluntary control of holding the rectal and bladder content can be voluntarily controlled due to anal sphincters 47 and puborectalis 46 muscle as well as pubourethralis.

FIG. 4 is presentation of the drawing 400 showing our inventive device Squatting Toilet Seat (STS) 35 that can be inserted to on the existing toilet seat or incorporated as a toilet seat fixed to the rim of the toilet bowl at the water tank along with toilet closure (not shown in the diagram).

The rest of explanation is same as FIG. 4.

FIG. 7 is presentation of the drawing 700 showing the sagittal section of our inventive Squatting Toilet Seat (STS) 35 shown in the FIG. 6, that can be inserted to on the existing toilet seat or incorporated as a toilet seat fixed to the rim of the toilet at the water tank along with toilet closure (not shown in the diagram). It is provided with urine draining depression 51 at the anterior end of the STS with wedge protruding into the interior of the toilet bowl to facilitate the urine that drips are drained with ease to the toilet bowl water. The rest of explanation is same as FIG. 4.

FIG. 8 is presentation of the drawing 800 showing the sagittal section of our inventive Squatting Toilet Seat (STS) 35 that is inserted to the existing toilet seat or incorporated as a toilet seat fixed to the rim of the toilet bowl at the water tank along with toilet closure 59, and the excreta drops into toilet bowl water 28. The rest of explanation is same as FIG. 4.

FIG. 9 is presentation of the drawing 900 showing western style toilet seat 60 on the rim 82 of the toilet bowl 84 and the sitting position of the person on the toilet seat to defecate or urinate. Note the anorectal junction (long arrow) expanded to show this sitting effect on the puborectalis muscle 46 that originates in pubic bone 45 encircles the anorectal junction of the rectum 44 and anal canal 47 with anal sphincters which opens on the buttocks skin 48 surface. Note the angle 51 created by the tension at the ano-rectal junction by the puborectalis muscle 46 contraction/tone arising from the pubic bone 45. The STS sits on the toilet rim 82, opening into toilet water 84, which receives the excreta 72 from the anal canal. If the stools are hardened, one may have to strain deeply by contracting abdominal muscles 49 and diaphragm to evacuate the bowl due to this acute angle created by puborectalis muscle sling that can create hemorrhoids, fissures, fistulae, anal infections and such that can be reduced using our inventive device Squatting Toilet Seat.

FIG. 10 is presentation of the drawing 1000 showing the use of our inventive Squatting Toilet Seat 35 positioned on the rim 82 of the toilet bowl 84 and note the squatting position of the person on the toilet seat with buttocks 72 protruding into the toilet bowl 84 produced by our toilet seat. Note the anorectal junction expanded to show this squatting position created by our STS and its effect on the puborectalis muscle 46 relaxation that encircles the junction of the rectum 44 and anal canal 47 which opens on the buttocks interspace skin 48 surface. Note the angle 51 created by the tension/tone at the ano-rectal junction by the puborectalis muscle 46 contraction is made more obtuse and brining anus in line with the rectum lumen 44 for easy movement of bowel contents through anus 48. The straight arrow shows the alignment of the rectum and anus to facilitate the evacuation of the stool fast with least strain and effort. Use of our inventive STS reduces the bent at anorectal angle and makes it more obtuse (see FIGS. 16. 17), rectum becomes in line with the anus for fast and easy bowel movement with least effort and least staining. The movement of the lower colon contents are facilitated by peristalsis 50 of the sigmoid colon and rectum with increased abdominal pressure and gravity.

FIG. 11 is presentation of the drawing 1100 showing another view of using our Squatting Toilet Seat 35 positioned on the rim 82 of the toilet bowl 84 and note the squatting position of the person on the toilet seat with buttocks 72 protruding into the toilet bowl 84 with anus pointed down towards center of toilet bowl in line with rectum by the use of our device. It is another view of using our STS as toilet seat during defection. Note the anorectal junction expanded to show this squatting position created by our STS and its effect on the puborectalis muscle 46 relaxation that encircles the junction of the rectum 44 and anal canal 47 which opens on the buttocks skin 48 surface. Note the angle 51 created by the tension at the ano-rectal junction by the puborectalis muscle 46 contraction is made more obtuse and brining anus in line with the rectum for easy movement of bowel contents through anus 48. The straight arrow shows the alignment of the rectum and anus to facilitate the evacuation of the stool with least strain and effort. Use of our inventive STS reduces the bent at anorectal angle and makes it more obtuse, rectum lumen becomes in line with the anal canal (straight arrows) for easy bowel movement as shown by plain arrows. The movement of the lower colon contents are facilitated by peristalsis, increased abdominal pressure and gravity due to relaxation of puborectalis muscle using our STS toilet seat.

FIG. 12 is a presentation of the drawing 1200 showing the sagittal section of our inventive Squatting Toilet Seat (STS) 35 that is inserted to on the existing toilet seat 60, and that has a cover 59 fixed to the rim of the toilet bowl 82. This STS can be moved from one bathroom to another bathroom toilet for use, and all the existing toilet seats do not have to be changed. It has elevated anterior extension 64 as described in FIG. 4, with projection 15 to anchor to the existing seat and allows anchoring of the STS to the toilet bowl rim 82 by this anterior anchoring lip 15. It is provided with urine draining depression (not shown, see FIGS. 6 and 7) at the anterior end of the Squatting Toilet Seat with wedge protruding into the interior of the toilet bowl to facilitate the urine that drips are drained with ease to the toilet bowl water 84. The rest of explanation is same as FIG. 4.

FIG. 13 shows the drawing of 1300 showing our inventive Squatting Toilet Seat (STS) 35 used by the person for evacuating the bowel contents and urine, sitting on the STS device shows how the lower end of the butt 72 protrudes into toilet bowl 84 below the rim of toilet. STS can be inserted to the existing toilet seat or incorporated as a toilet seat fixed to the rim of the toilet seat at the water tank along with toilet closure.

FIG. 14 illustration 1400 showing our inventive Squatting Toilet Seat (STS) 35 used by the person for evacuating the bowel contents in squatting position by sitting on the STS device and the mechanism of the device and how it helps in the act of defecation as well as urination. STS can be inserted to the existing toilet seat or incorporated as a toilet seat fixed to the rim of the toilet seat as described in above diagrams. STS helps to produce squatting position to helps to increase the intra-abdominal pressure (multiple arrows) due to contraction of diaphragm 53 and abdominal wall muscles 54. Increased abdominal pressure shown as arrows, pushes the undigested food content of lower colon 43 and to the rectum 44, out to the anal canal 47 to be evacuated through the anal opening 48 as natural toilet posture simulating squatting method of emptying our lower colon to eliminate body waste comfortably, fast, and easily as practiced in many Asiana countries. This STS 35 toilet seat posture affects our body's rectal evacuation system immensely and provides correct toilet posture that is necessary for smooth and fast release of waste material from the bowels including urine without any or a less amount of straining to increase the release of intra-abdominal contents.

FIG. 15 shows average bowel movement frequency per day by an individual and the use of toilet for defecation and urination. The toilet is also used for urination between 7-14 times a day depending on the age, sex, and health condition of the urogenital system. Hence using our Squatting Toilet Seat can facilitate both the bowel movement and urination no matter how many times one uses it.

FIG. 16 is illustration 1600 showing the acute anorectal angle 51 in sitting position on the traditional toilet due to puborectalis muscle 46 pulling and creating the angle between the rectum 44 and the anus 47 and is responsible holding continence of the bowel voluntarily.

FIG. 17 is illustration 1700 showing the obtuse anorectal angle 51 in squatting position on the Squatting Toilet Seat toilet due to puborectalis as well as pubourethralis muscle 46 relaxation, thus reducing the angling between the rectum 44 and the anus 47 and is responsible making the rectum 44 lumen in line with the anal canal 47 opening for easy rectal collection move during bowel movement without straining rapidly with ease.

FIG. 18 is the illustration 1800 showing our inventive Squatting Toilet Seat 35 that incorporates visible violet-blue spectrum light 55 to sterilize the toilet bowl and deodorizer emitter 64 to prevent bad odors emanating from the toilet use. The deodorizer can be incorporated in the device, so that it geminates inside the toilet bowl. The LED visible violet-blue light are incorporated into the seat with a groove undersurface to allow the embodiment to be incorporated. These lights are arranged in a strip or arrays that emit powerful visible violet-blue light down the inside the toilet bowl ridge, whose illumination covers the entire toilet bowl and the STS to kill any, and all, microbials that are sticking to the bowl and its reserve water after defecation and urination. This will eliminate the use of toilet bowl disinfectants to sterilize the toilet bowl. The energy source for this embodiment is provided by battery pack or home electrical outlet. This can blue light sterilizer unit can be also a separate unit inserted under the STS through a wiring channel to facilitates its use as an independent unit with the STS unit or in a regular toilet which does not have the STS provided. This Figure shows that we incorporate ancillary toilet night/day light to light up the toilet bowl (FIGS. 4-8, 13-14) with antiseptic powerful visible violet-blue spectrum light irradiation. Further, the light and the deodorizer can be activated by movement of the toilet seat cover to the closed position.

FIG. 19 is the illustration 1900 showing our inventive Squatting Toilet Seat 35 placed on a portable chair 88 which can be used as a bedside toilet or used during camping and outdoor activities that used flexible legs that adjust and fold (not shown in the diagram) for convenience to carry to different locations. The toilet is provided with a toilet cover 59 which covers our Squatting Toilet Seat 35 placed on the chair 88. It has a toilet bowl 84 that can be lined with toilet bag 84a that can be conveniently removed after each evacuation of bowel and urine for hygienic sanitary purpose. The chair is provided with adjustable legs 89 to adjust the height of the chair and to adjust the toilet seat to a convenient height of the user, so the legs of user are flat on the floor while in use.

FIG. 20 is the illustration 2000 showing our inventive Squatting Toilet Seat 35 with a separate visible violet blue light module 55 that is attached to the back underside of the toilet bowl cover inside the toilet seat hinge assembly using an attachment clip which is attached to a power supply 55a that is affixed to the toilet water tank but can also be applied to any smooth surrounding toilet surface. The visible violet blue light module automatically turns on when the toilet cover is moved into the close (horizontal) position for a set time duration for sterilization of toilet bowl and the other surrounding surfaces of the toilet seat before automatically shutting off at set time. This embodiment is of most useful besides using on our regular toilet for the toilet lids in aero plane lavatories, recreational vehicles, on Porto Poti, bedside toilets and camp site toilet to keep them completely sterile.

Use of Blue Light Embodiment with Squatting Toilet Seat to Keep the Toilet Bowl Sterile without Microbial Contaminants

The visible violet-blue spectrum light incorporated in the Squatting Toilet Seat or used with existing toilet seat acts as killer of viruses, microbes, yeast, protozoa and such in the toilet bowl water and its exposed surrounding surfaces. The visible violet-blue light is already in use to disinfect bacterial contamination of blood and plasma that are used for transfusions, which are performed millions of times in the US and around the world, and also used in water decontamination

Bacterial contamination of vivo stored injectable biological fluids such as blood and blood components preserved in plasma is a major complication for transfusion medicine, resulting in both wasteful discarding of valuable blood products and, more significantly, health risks for recipients of contaminated donor blood [Burnouf T., Radosevich M., Reducing the risk of infection from plasma products: specific preventative strategies. Blood Reviews. 2000; 14(2):94-110. Maclean M et al. A New Proof of Concept in Bacterial Reduction: Antimicrobial Action of Violet-Blue Light (405 nm) in Ex Vivo Stored Plasma. J Blood Transfus. 2016; 2016: 2920514]. Maclean et al. (2016), report the first proof-of-concept results on the use of a novel visible 405 nm visible violet-blue light method that does not require the addition of photosensitive chemicals for inactivation of bacterial and other microbial pathogens in plasma which is akin to the toilet contaminated water and toilet bowl surrounding surfaces. Our method utilizes light with an optimal wavelength, which causes photoexcitation of endogenous microbial porphyrin molecules and oxidative damage through reactive oxygen species that are multiplying in the toilet bowl after defecation and urination. Visible violet blue spectrum light has previously been shown to inactivate a wide range of bacterial pathogens and is used widely in disinfection technology; hence we use this technology to keep the toilet bowl and its remanent water sterile from the fecal and urine microbial contamination.

This visible violet-blue spectrum light is incorporated and/or separate unit into our inventive device Squatting Toilet Seat as well used with existing toilet seats and it is effective killing the bacterial and their spores in the toilet bowl and urinal. The blue light be incorporated into toilet cover of any toilet bowl to sterilize the toilet bowl, residual water, toilet seat and ambient air before and after use of the toilet.

Studies have demonstrated increased susceptibility of viral, bacterial cells, spores and fungus compared to their mammalian counterparts—potentially providing the ability to preferentially inactivate microbial contamination in wound and tissue environments now in the toilet bowl. The visible violet-blue spectrum light involves the photoexcitation of endogenous porphyrin molecules in microbes in the toilet bowl, a process which generates:

• • a) reactive oxygen species (ROS), including singlet oxygen (1O2),
  • c) superoxide anion (O2-),
  • d) hydrogen peroxide (H2O2) and
  • e) hydroxyl groups (OH),These free radical generated by visible violet-blue spectrum light are toxic to microbes in the toilet bowl, contaminated by coming in contact with toilet bowl and its water are killed. Overall, studies provide the first evidence that visible violet-blue light has the ability to inactivate bacterial contamination within or outside the biological tissue that are exposed to this irradiation in structures like toilet bowl and its residual water. Our inventive Squatting Toilet Seat device with visible violet-blue spectrum light fluorescence kills free floating microbes in the toilet bowl water, toilet interior surface and its seating may even skin surface microbes of the buttocks exposed in the toilet bowl during use.

Scented Squatting Toilet Seat in Our Inventive Squatting Toilet Seat

Bathroom deodorizers are very well known in the art. Many attempts have been made to control the odor that is commonly found in a bathroom containing a standard toilet as such odors are offensive and embarrassing to other users, although it does not eliminate the microbes of the toilet bowl. Most commonly, various spraying devices have been used in the air surrounding the toilet. Even though this method is effective for masking the odor, it is not very practical for public bathrooms, since there is a natural reluctance to touch things in public restrooms including the toilet seat, faucets, etc. There are many other methods to deodorize the bathroom due to use of toilet and the smell that emanates from the bowel movement. In general, none of the existing ventilation systems for removing odors directly at the toilet have been commercially successful. The present invention is directed to a device used in conjunction with our squatting toilet seat in order to disperse a pleasant-smelling spray into the air. By automatically disperse a pleasant-smelling spray directly into the toilet bowl, neutralizing the odor while it is still confined within the toilet bowl, without the user intervention.

The use of our invention Squatting Toilet Seat from early life ensures that there will be no continuous trauma to the anus and rectum linings due to hardened stools and the excreta evacuated with least or no straining. It is obvious from the above studies that puborectalis muscle relaxion is important for easy, smooth and quicker movement of stools

The Puborectalls Muscle of the Pelvic Floor and Levator Ani Muscle

The puborectalis muscle (FIGS. 1-3, 9-14) is a U-shaped sling suspends the anorectal part of the colon in the pelvic floor besides supporting pelvic organs. These muscles extending backwards from the bodies of the pubic bones (origin of the puborectalis muscle), past the urogenital hiatus, around the anal canal, urethra, and vagina in the female. Its tonic contraction and tension bends the anal canal anteriorly, creating the anorectal angle (±90 degrees FIG. 2) at the anorectal junction (where the rectum meets the anus. By using our Squatting Toilet Seat allows the rectal and anal lumen in line for easy, fast evacuation of bowel contents during defecation. The main function of this thick muscle is to maintain fecal and urinary continence—during defecation and urination this muscle relaxes allowing the rectal contents to be evacuated through the anal canal and its opening outside of our body. Some fibers of the puborectalis muscle (pre-rectal fibers) form another U-shaped sling that flank the urethra in the male and the urethra and vagina in the female (in some textbooks they appear as pubovaginalis and sphincter urethrae/vaginae). These fibers are very important in preserving urinary continence and preventing the prolapse of the pelvic organs especially during an abrupt increase of the intra-abdominal pressure i.e., during sneezing, coughing, lifting weights etc. If the control of puborectalis muscle is weak or lost, it can result in stress incontinence. This levator ani muscle can be strengthened by Kegel pelvic floor exercises and use of our Squatting Toilet Seat helps to evacuate the bladder completely, allowing the bladder to fill completely that results in less urge to urinate, reducing the frequency of micturition.

Anus, Defecation and Use of Our Squatting Toilet Seat

The anus is the terminal opening of the alimentary canal, but this term is used for the combination of the internal and external anal sphincters that control the defecation involuntarily or voluntarily. The anal canal is about 2 inches long and lies between the termination of the rectum and the anal orifice and is angled at anorectal junction to create angle which helps to maintain continence when the urge to empty bowels develops. It is here that the use of our Squatting Toilet Seat plays a role to make rectum in line with the anus with the least angling for the evacuation of excreta with ease and fast.

Urination: How Many Times One Uses Toilet for Urination (Pee) and how Our Squatting Toilet Seat Facilitates Urination.

How often you urinate is actually a very important sign of your overall health, beginning in infancy and continuing throughout your life. Frequency of urination refers to the number of times you go to the toilet to pass urine in a day. If you need to go to the toilet very often, more than seven times a day on drinking approximately 2 liters of fluid, you may have a urinary frequency problem. This can be caused by an overactive bladder or prostate afflictions. The bladder might contract even when it doesn't need to; for example, if your bladder only has a small amount of urine in it, or it may be oversensitive. This means that you feel the need to go to the toilet more often. Frequency is often associated with urgency and urge incontinence. By reducing the residual urine in the urinary bladder by the use of our Squatting Toilet Seat can reduce this condition, by facilitating an easy urine flow due to relaxation of pubourethralis muscle with complete emptying of the bladder.

Urinary Incontinence and Use of Our Squatting Toilet Seat to Help the Afflicted

The Squatting Toilet Seat provides a provision for safe urination without spilling outside the toilet bowl (FIGS. 1-1a, 1b, 4-12), this is specially so for female who uses squatting position on the toilet for urination and may reduce the frequency of urination and incontinence. The current step stools have no provision to direct the urine to the toilet bowl, especially in females, and will ensure the complete emptying of the bladder by relaxing the pubourethralis muscle. Many women, in fact, 1 in 3, experience certain forms of urinary incontinence which can be eliminated or reduced using our Squatting Toilet Seat due to complete emptying of the bladder without any residual urine.

Pelvic Floor Role in Defecation and Urination

The pelvic floor is a system of muscles, ligaments, tissue and nerves arranged at the bottom of the pelvis that form a hammock supporting female bladder and uterus, rectum and prostate in male. A women's pelvic floor goes through an assortment of changes, especially during pregnancy, childbirth, C-section, menopause and old age. As a matter of fact, natural childbirth, short or prolonged delivery, and c-sections can increase your chances of developing urinary incontinence due to weakening of pelvic floor muscle levator ani muscle after having children and also prostate hypertrophy in the aged male. Multiple pregnancy and prostate afflictions enhance the possibility of urinary incontinence which may be helped by use of our Squatting Toilet Seat.

Act of Defecation and Use of Our Squatting Toilet Seat to Facilitate this Natural Processes

Normal defecation and maintenance of fecal continence involve a highly coordinated mechanism that involves the levator ani, puborectalis, and the external (EAS) and internal anal sphincter (IAS) muscles of the anus which are under the control both voluntary and involuntary. The pelvic floor is composed of the levator ani, the underlying sheets of which form a sling around anorectal junction (FIGS. 1-2, 2a 2b, 9-14). The levator ani, puborectalis, and external anal sphincters (EAS, -FIGS. 2, 3) are skeletal muscles that constantly maintain tone and sustain pelvic organs in place against the forces of gravity and peristalsis. Synchronized contraction of these muscles prevents the involuntary loss of stool and helps maintain the regular pattern of defecation. One can elect to defer defecation, nevertheless, by volitionally contracting the puborectalis muscle and EAS.

The rectum is filled with intestinal undigested food waste until just before defecation. Perception of rectal contents and pressures is essential for signaling voluntary contraction of the anal sphincter (FIGS. 3, 9-14). Normal defecation begins with reflexes triggered by rectosigmoid distention produced by approximately 200 mL of feces. A recto rectal reflex occurs in which the bowl proximal to the distending bolus contracts and the bowel wall distally relaxes, serving to propel the bolus further caudad—to the anal canal. This relaxation, called the recto anal inhibitory reflex, correlates with the urge labeled “the call to stool.” One can then volitionally contract the levator ani to open the proximal anal canal and relax the EAS and puborectalis muscles. This allows a straighter, shorter, and more open anorectal passage, which permits the bolus to pass. Increasing the intraabdominal pressure by squatting and by Valsalva's maneuver assists bolus elimination.

Continence is maintained by the anal sphincter mechanism, which consists of the internal anal sphincters (IAS), external anal sphincters (EAS), and puborectalis muscle (see 1, 1a, 1b, FIG. 3). Anal pressure can be increased volitionally by contracting the EAS and puborectalis muscles (FIG. 3, 11, 12, 14). The EAS is physically larger than the IAS, and its contraction is under both reflex and volitional control. Normal baseline reflex action of the anorectal mechanism allows spontaneous stool elimination. The remarkable degree of learned EAS coordination allows the selective discrete passage of gas while juggling a variable mixture of solids, liquids, and gases.

Defecation Dysfunction: Constipation and use of our Squatting Toilet Seat

Constipation can be a huge enigma in neurologic states and can be the result of not eating fiber rich diet and having a sedentary lifestyle. Infrequent, incomplete emptying of hard stools is due to decreased water and electrolyte secretion into the colon lumen, resulting from reduced excitation of the secretomotor neurons. A lack of rectal sensation and a decreased urge to defecate can be strongly associated with constipation in various conditions that present with lesions in the brain, spinal cord, sacral nerves, and hypogastric and pudendal nerves. Outlet obstruction can ensue because of delayed colonic transit times and lack of perineal and recto anal sensation. Our inventive Squatting Toilet Seat allows a person to relax the puborectalis muscle by inducing a better posture for defecation for induce easy fast passage of bowel movements.

Defecation Dysfunction: Fecal Incontinence (FI) and use of our Squatting Toilet Seat

True fecal incontinence is described as an unconscious loss of stool, often occurs in neurologic conditions with lesions affecting the lumbar spinal cord, cauda equina, S2-S4 nerves, pudendal nerve, and pelvic floor nerves that supply the muscles around anorectal regions. It is important to rule out overflow incontinence resulting from constipation. With this condition, use of our Squatting Toilet Seat will completely relax the puborectalis muscle and easy fast passage of bowel contents completely and thus delay the incidence of fecal incontinence.

Benefits of Using Our Inventive Squatting Toilet Seat

According to the present Squatting Toilet Seat invention, allows for smoother and faster defecation by converting the acute angle formation between the rectum and the anus to an obtuse angle during defecation by correcting the posture of a user into a squatting posture instead of the common sitting posture used by billions. Consequently, defecation becomes a fast, easy, pleasant experience with little or no straining when evacuating the bowels and may even prevent a person's legs from becoming numb due to long sitting with results in pressure on the leg nerves. Hence the advantages using our Squatting Toilet Seat are as follows:

• • a) Bowel evacuation is convenient, easier and faster with little or no straining.
  • b) It prevents fecal stagnation and helps to evacuate the rectum completely due to proper alignment of rectum with anus due to relaxation of puborectalis muscle.
  • a) It guards the pelvic nerves from becoming overstretched and damaged due to acute stretching of nerve supply to the urogenital organs such as anus, anorectal junction, prostate, bladder, and uterus sue to straining.
  • b) reduces the frequency of straining episode during the bowel movement due to reducing the stretching of anorectal angle caused by ano-rectalis muscle.
  • c) Bending of the torso on the thighs temporarily blocks the ileocecal valve due to increased abdominal pressure during squatting position with reduced chance of contaminating the small intestines from colon contents retrograde flow and its bacterial colony.
  • d) Relaxes puborectalis muscle which usually blocks the passage of rectal contents into the anus for evacuation with ease.
  • c) Draws the thighs close to abdomen which supports the colon that runs around the periphery which presses the colon contents of the abdominal cavity which prevents hernia and prolapse of the pelvic organs due to increased abdominal pressure during defecation.
  • d) Squatting is useful during pregnancy by preventing intra-abdominal pressure exerted on the uterus when using the toilet. Regular squatting is also beneficial for delivery.
  • e) Although causal relationship has not been completely established, it is known that those who squat during bowel evacuation have shown that the incidence of hemorrhoids is uncommon.
  • f) Having a knees-up posture on the toilet induces an anatomical benefit of squatting during defection. It negates the need to use a foot stool and a person doesn't have to worry about storing it, finding it, and positioning it.
  • g) Helps females to urinate with ease and promotes evacuation of the blood and blood clumps during menstruation due to relaxation of pubourethralis and pubovaginalis-urethralis muscles of levator ani along with puborectalis muscle.
  • h) Provides automatic disinfection and sterilization of the toilet bowl and surrounding surfaces using visible violet-blue spectrum light that will eliminate the need to scrub and clean the toilet bowl using antimicrobial sprays and relieve the possible fear of getting infections or contaminated.
  • i) It is provided with anti-viral, anti-bacterial, anti-fungal, anti-protozoal-microbiocidal violet blue light emitted into toilet bowl water, surface and ambient air which automatically turns on and off at set time. Such light is provided attached to the undersurface of toilet seat or toilet cover that will sterilize the entire toilet from toilet seat to toilet water pool, toilet bowl and ambient air. Such an embodiment is of great benefit in public lavatories, airplane toilet, porta Poti, camping sites and on best side toilet chairs to keep the toilet sterile before and after use.Numerous modifications and alternative arrangements of steps explained herein regarding our invention may be devised by those skilled in the art without departing from the spirit and scope of the present invention and the appended claims are intended to cover such modifications and arrangements.
