Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The invention relates to bedpans. More particularly, the invention relates to a bedpan which is easier to use, more comfortable and better adapted to function as intended.




2. Description of the Prior Art




Bedpans have been in use in various forms for many years. Bedpans generally provide those individuals confined to a bed an acceptable way in which to dispose of bodily waste. However, while technology and ingenuity have been applied in many areas of medicine, bedpans currently used today are substantially similar in design to those used for the past 100 years.




With that in mind, standard professional bedpans have many problems. They are difficult to place under a patient, they are uncomfortable to use and they are difficult to clean. Prior bedpans commonly require that the patient be rolled on his or her side while the bedpan is placed under the patient so that he or she may be rolled back onto the bedpan.




The process of rolling a patient on his or her side in order to properly position a bedpan presents a substantial problem for those patients who are not in condition to be subjected to the rigors of being rolled around a bed. Even where the patient is well enough to be rolled on his or her side, the caregiver must exert great physical force to rollover of patient who might not have the physical ability to assist the caregiver in positioning the bedpan.




Once the bedpan is properly positioned under the patient, current bedpan designs are not well suited for positioning adjacent the rectum of the patient and are consequently often uncomfortable. For example, the fact that prior bedpans lift the patient's midsection, makes it difficult for those with sensitive backs or hip problems to use these bedpans. In fact, it is often impossible for those recovering from back or hip surgery to use any currently available bedpans.




In addition to lifting the midsection of an individual in an undesirable manner, current bedpans push the buttocks together, causing the patient to lose the sensation required for moving his or her bowels. If the patient is, however, finally able to relax enough to move his or her bowels, the hospital staff is left with a much greater mess than if a toilet were used by the patient. With this in mind, standard industry bedpans are difficult to clean, because solid waste must be wiped, or hosed, out into a toilet where spillage is likely.




A bedpan taking advantage of current technology and anatomical knowledge is, therefore, needed. The present invention provides such a bedpan. The inventors of the present bedpan have created various mold of the human pelvic region and applied digitally designed computer models in developing a bedpan which will truly address the needs of bedridden patients. In addition to considering the bone structure associated with the pelvic region, the inventors of the present bedpan considered tissue movement associated with the use of bedpans. The technologically advanced techniques applied in the development of the present bedpan have resulted in a bedpan offering improved comfort, use and functionality.




SUMMARY OF THE INVENTION




It is, therefore, an object of the present invention to provide a bedpan providing ease of use, comfort, and cleanability. The bedpan includes a body member defining a reservoir shaped and dimensioned for receiving bodily waste. The body member includes a closed base section adapted for retaining bodily wasted deposited within the bedpan and an open support section. The support section includes a central opening providing access to the reservoir defined by the body member. The central opening is defined by first and second inwardly inclined walls extending from a first end of the body member toward a second end of the body member. The support section further includes a forward support surface adjacent the first end of the body member. The forward support surface has a forward end adjacent the base member and a rearward end adjacent the first and second inwardly inclined walls, wherein the forward support surface is generally horizontal and tapers downwardly as it extends toward the base section. The forward support surface and first and second inwardly inclined walls being so positioned to lift the pelvic region as the first end of the body member is slid under a patient and separate the buttocks to facilitate bowel movement.




It is also an object of the present invention to provide a bedpan wherein the first inwardly inclined wall has an outer surface which is of a generally concave shape and the second inwardly inclined wall has an outer surface which is of a generally concave shape.




It is another object of the present invention to provide a bedpan wherein the first inwardly inclined wall is a mirror image of the second inwardly inclined wall.




It is a further object of the present invention to provide a bedpan wherein the first inclined wall has a first end adjacent the forward support surface and a second end adjacent the second end of the body member. The first end of the first inclined wall is coterminous with the forward support surface. Similarly, the second inclined wall has a first end adjacent the forward support surface and a second end adjacent the second end of the body member, wherein the first end of the first inclined wall is coterminous with the forward support surface.




It is also another object of the present invention to provide a bedpan wherein the first and second inclined walls increase in height as they extend from the first end of the body member to the second end of the body member.




It is yet another object of the present invention to provide a bedpan wherein the first inclined wall has a first end adjacent the forward support surface and a second end adjacent the second end of the body member, the second end of the first inclined wall being joined with the second end of the second inclined wall adjacent the second end of the body member.




It is still another object of the present invention to provide a bedpan wherein the forward support surface inclines upwardly as it extends from the first end of the body member toward the second end of the body member.




It is a further object of the present invention to provide a bedpan wherein the body member includes first and second lateral support surfaces respectively adjacent the first and second inwardly inclined walls.




It is still a further object of the present invention to provide a bedpan wherein the first and second lateral support surfaces are coterminous with the forward support surface adjacent the first end of the body member.




It is also an object of the present invention to provide a bedpan wherein the first inclined wall has a first end adjacent the forward support surface and a second end adjacent the second end of the body member and the second inclined wall has a first end adjacent the forward support surface and a second end adjacent the second end of the body member. A concave opening is defined by the first end of the first inclined wall and the second inclined wall, the concave opening being shaped and dimensioned for positioning of patient's rectum adjacent thereto.




It is still another object of the present invention to provide a bedpan wherein the forward support surface includes a central ridge.




It is yet another object of the present invention to provide a bedpan wherein the central ridge extends between first end of the body member and the central opening.




Other objects and advantages of the present invention will become apparent from the following detailed description when viewed in conjunction with the accompanying drawings, which set forth certain embodiments of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT




The detailed embodiment of the present invention is disclosed herein. It should be understood, however, that the disclosed embodiment is merely exemplary of the invention, which may be embodied in various forms. Therefore, the details disclosed herein are not to be interpreted as limited, but merely as the basis for the claims and as a basis for teaching one skilled in the art how to make and/or use the invention.




With reference to

FIGS. 1

to


5


, a bedpan


10


in accordance with the present invention is disclosed. The bedpan


10


is designed to provide for ease of use, comfort, and cleanability. In fact, available technology has been applied in developing the present bedpan


10


so as to offer patients previously unrealized comfort and convenience.




The bedpan


10


generally includes a body member


12


defining a reservoir shaped and dimensioned for receiving bodily waste. The body member


12


includes a closed base section


14


adapted for retaining bodily wasted deposited within the bedpan


10


and an open support section


16


.




In accordance with a preferred embodiment, the closed base section


14


is shaped and dimensioned for the receipt and temporary storage of bodily waste. The base section


14


is, therefore, provided with a substantially flat bottom wall


18


having upstanding walls


20


extending therefrom. The forward end


21


of the base section


14


extends upwardly as it meets the support section


16


. The bottom wall


18


and upstanding walls


20


form a basin in which bodily waste is collected prior to disposal. In addition, the substantially flat surface provided by the bottom wall


18


permits those using the present bedpan


10


to lie the bedpan


10


on a countertop or worksurface without worrying that the bedpan


10


will spill over.




As will be better appreciated based upon the subsequent discussion regarding use of the present bedpan


10


, the exterior surface


22


of the bottom wall


18


is provided with adhesive tape


24


covered with a release sheet


25


to facilitate secure positioning when the bedpan


10


is placed beneath a patient. Specifically, once exposed, the adhesive tape


24


grips a support surface when the bedpan


10


placed under the patient, but provides relatively free movement when the bedpan


10


is moved under the patient with the release sheet


25


covering the adhesive tape


24


. While a specific gripping surface is disclosed above in accordance with a preferred embodiment of the present invention, various other gripping designs may be applied without departing from the spirit of the present invention.




As mentioned above, an open support section


16


is positioned above the based section


14


. The open upper support section


16


is shaped and dimensioned to lift a patient upon the bedpan


10


and position his or her rectum for collection of bodily waste within the present bedpan


10


. The support section


16


includes a central opening


26


providing access to the reservoir defined by the body member


12


. The central opening


26


is defined by first and second inwardly inclined walls


28


,


30


extending from a first end


32


of the body member


12


toward a second end


34


of the body member


12


. The support section


16


further includes a forward support surface


36


adjacent the first end


32


of the body member


12


. The forward support surface


36


has a forward end


38


adjacent the inclined forward end


21


of the base section


14


and a rearward end


40


adjacent the first and second inwardly inclined walls


28


,


30


. The forward support surface


36


is generally horizontal and inclines upwardly as it extends from its forward end


38


adjacent the base section


14


toward its rearward end


40


adjacent the first and second inwardly inclined walls


28


,


30


. The forward support surface


36


and first and second inwardly inclined walls


28


,


30


are so positioned to lift the pelvic region as the first end


32


of the body member


12


is slid under a patient and separate the buttocks to facilitate bowel movement.




More specifically, and with reference to

FIGS. 1

to


5


, separation of the buttocks is facilitated by the central ridge


37


formed along the surface of the forward support surface


36


. The ridge


37


longitudinally extends along the center of the forward support surface


36


from the forward end


38


of the forward support surface


36


adjacent the base section


14


to the point at which the forward support surface


36


and the central ridge


37


meet the central opening


26


. In practice, and as will be discussed below in greater detail, the central ridge


37


functions to contact the buttocks as the bedpan


10


is slid under the patient and separates the flesh surrounding the perineum to reveal the individual's anus directly over the opening of the bedpan


10


.




The first inwardly inclined wall


28


and the second inwardly inclined wall


30


are mirror images of each other. Each of the first and second inwardly inclined walls


28


,


30


includes an outer surface


42


,


44


shaped and dimensioned for receiving the buttocks of a patient. The outer surface


42


,


44


of each inclined wall


28


,


30


is generally concave. The concave shape conforms to the patient's body and enhances user comfort as the bedpan


10


is slid beneath the patient.




The first inwardly inclined wall


28


includes a first end


46


adjacent the forward support surface


36


and a second end


48


adjacent the second end


34


of the body member


12


. Similarly, the second inwardly inclined wall


30


has a first end


50


adjacent the forward support surface


36


and a second end


52


adjacent the second end


34


of the body member


12


. The first and second inwardly inclined walls


28


,


30


each increase in height as they extend from the first end


32


of the body member


12


toward the second end


34


of the body member


12


. In fact, the first end


46


of the first inwardly inclined wall


28


flows into the forward support surface


36


such that the first end


46


of the first inclined wall


28


is coterminous with the forward support surface


36


. The first end


50


of the second inwardly inclined wall


30


similarly flows into the forward support surface


36


such that the first end


50


of the second inwardly inclined wall


30


is coterminous with the forward support surface


36


.




The second ends


48


,


52


of the first and second inwardly inclined walls


28


,


30


meet at the second end


34


of the body member


12


to form a wall


54


blocking urine being expelled by a patient. That is, the second ends


48


,


52


of the first and second inwardly inclined walls


28


,


30


are joined to form an upwardly extending wall


54


at the second end


34


of the body member


12


. In fact, the first and second inwardly inclined walls


28


,


30


curve inwardly, outwardly and inwardly before they meet at the second end


34


of the body member


12


. In this way, they create a handle/trough


56


for capturing urine. The meeting point of the first and second inwardly inclined walls


28


,


30


is shaped to function as a wall, handle and pouring spout (as will be discussed below in greater detail).




With reference to the forward support surface


36


, it inclines upwardly as it extends from the first end


32


of the body member


12


toward the second end


34


of the body member


12


. In fact, the meeting point of the forward support surface


36


and the base section


14


, substantially resembles a duck-bill. In accordance with a preferred embodiment of the present invention, the forward support member


36


is inclined at an angle from approximately 5° to approximately 20


20


, although other angular orientations may be employed without departing from the spirit of the present invention.




As mentioned above, the first inwardly inclined wall


28


has a first end


46


adjacent the forward support surface


36


and the second inwardly inclined wall


30


has first end


50


adjacent the forward support surface


36


such that a concave opening


58


is defined by the first ends


46


,


50


of the first inwardly inclined wall


28


and the second inwardly inclined wall


30


. The concave opening


58


is shaped and dimensioned for positioning of patient's rectum adjacent thereto.




The body member


12


also includes first and second lateral support surfaces


60


,


62


respectively adjacent the first and second inwardly inclined walls


28


,


30


. The first and second lateral support surfaces


60


,


62


are coterminous with the forward support surface


36


adjacent the first end


32


of the body member


12


and provide additional user support when the present bedpan


10


is placed beneath a patient.




With reference to

FIGS. 6

,


7


and


8


, the present bedpan is utilized in the following manner. While the present description relates to use of the present bedpan while the patient is in a flat position, the bedpan may be raised to any angle so that a patient in a seated position may use the present bedpan.




The patient's legs are first positioned such that the knees are approximately one foot apart. There is no need to bend the patient's legs. A paper insert


63


may then be positioned within the bedpan


10


. The paper insert


63


is formed to fit the base section


14


of the bedpan


10


and may be readily positioned therein by the user. The paper insert


63


is provided with a tab


63




a


, allowing a caretaker to easily grab hold of it after patient use. The nurse then stands to either side of the bed and rests the bedpan


10


between the patient's knees with the duck-bill shaped forward support surface


36


pointed toward the point where the bed sheet comes into contact with the patient's skin.




The bedpan


10


is then slid forward at an angle that will separate the person from the mattress. The leading edge, or first end


32


, of the bedpan


10


has an inverted T-shape which will match the shape formed by the meeting of the mattress, the patient's buttocks and the perianal region. This shape attempts to mimic the inverted T-shape formed between a bed and an individual's buttocks when the individual is lying on a bed. By creating the present bedpan


10


with a leading edge


32


having an inverted T-shape, the bedpan


10


is able to enter the space between the bed and buttocks while lifting the buttocks and depressing the mattress. Simultaneously, the central ridge


37


, working in conjunction with general shape of the bedpan


10


, gradually spreads the flesh of the buttocks. Continued forward movement of the bedpan


10


into position allows the central ridge


37


to separate the flesh surrounding the perineum to reveal the individual's anus directly over the opening of the bedpan


10


.




The back end, or second end


34


, of the bedpan


10


is equipped with a trough/handle


56


shaped to accommodate the left or right hand. The bedpan


10


is gripped firmly by this handle


56


and worked between the patient and the mattress with a side to side, zigzag motion.




While the bedpan


10


is positioned in this manner, the patient need not raise his or her pelvis. The first end


32


of the bedpan


10


may be pushed down into the bed to more easily slide the bedpan


10


under the patient and lessen the chances of catching on the softer skin of older patients (although the leading edge is rounded to avoid pinching of flesh).




As the bedpan


10


is slid under the patient, the nurse will notice the folds of the skin around the anus being pushed proximally. As mention above, this movement of the flesh around the perineum is achieved by providing an inverted T-shaped leading edge


32


and central ridge


37


which function to separate the buttocks and the flesh around the perineum to expose the individual's anus. When the nurse is able to clearly view the patient's anus and the first end


32


of the bedpan


10


is pressed against the front of the pelvis, the bedpan


10


has been introduced far enough under the patient. The patient's legs will then be draped across the support section


16


of the bedpan


10


.




With regard to male patients, they will find that their testicles have been pushed up and out of the way by the bedpan


10


. Female patients will find that the walls


28


,


30


of the bedpan


10


press into their flesh on either side of the mound pubis.




Additional confirmation that the bedpan


10


is in place will come from the patient who will feel that the first end


32


of the bedpan


10


has moved past their tailbone and that their buttocks are comfortably spread as they would be if they were sitting on a toilet.




Once properly positioned, the bedpan


10


may be left in place for long periods of time without discomfort to the patient. The bedpan


10


will remain locked in position by the friction between the bed and the patient's legs. The patient is then free to engage in a bowel movement and/or urination at his or her convenience. Male patients will be required to either direct their penis into the bedpan


10


, or use an optional snap in tube (not shown) designed for this purpose. The tube will be slid into the pan in the handle area and remains locked in place. The flexible tube is then directed towards the patient and the penis is slipped inside. Urine is then directed by the tube into the bedpan


10


.




After the bedpan


10


has been used, the bedpan


10


is slid out from under the patient by pulling on the handle


56


backwards away from the patient in a zigzag motion. The hand indentations


64


,


66


on either side of the bedpan


10


may also be used. The flat bottom wall


18


of the bedpan


10


permits it to be securely placed on a mattress or table without worry that the contents will be spilled out. The bedpan


10


is then carried to the toilet by using the handle/trough


56


, the side indentations


64


,


66


or resting the flat bottom wall


18


on the nurse's palm. As the paper


63


with the stool on it is pulled out into the toilet, the bedpan


10


is tipped so that the fluid is poured out of the handle/trough


56


, which is shaped to act as a pour spout. The paper


63


can also be used to dump the stool sample onto a weight scale if desired.




In summary, the present bedpan has been designed with three major features. First, the bedpan is designed to be slipped under a patient with minimal effort. Second, the bedpan is comfortable enough to leave in place for long periods and is not injurious to patient's with sensitive back problems. Third, the present bedpan provides easier cleanup than traditional existing bedpans.




The bedpan is designed to be easily slipped under a patient. The front end of the pan is shaped somewhat like the combination of a duckbill and a saddle. The bedpan is introduced between and under the patient's legs with the legs slightly apart. The patient may be laying flat and also be elevated as high as 30 or 40 degrees. The caregiver then grasps the handle and slides the pan under the patient while working the pan from side to side. Adhesive tape on the bottom of the pan helps to secure the pan under the patient. As the bedpan is slipped under the patient, the duckbill/saddle portion of the pan slides between the bed and the patient's buttocks, causing a double wedge action which depresses the mattress and lifts the patient's buttocks tissue without having to lift the patient. Additionally, a vertically oriented wedge (i.e., ridge) separates the lobes of the buttocks to expose the anus. In accordance with a preferred embodiment of the present invention, the outside surface of the bedpan may be textured such that it will slide easily over damp skin.




With regard to user comfort, the pan is designed to fit snugly against the pelvic curve from the front as it passes the tailbone. In fact, the pan is substantially similar to sitting upon a saddle. Patients may feel as though nothing is under them, although they will feel that their buttocks are properly spread in preparation for a bowel movement in a manner similar to sitting upon a standard toilet. User comfort is further enhanced by the fact that the patient's pelvis is not lifted or rotated in the process of inserting the pan. This allows the pan to be left in place for hours if necessary. The patient will feel secure that the bedpan cannot shift under them since it is locked between their upper thighs and the mattress.




The cleaning process is improved by the use of disposable paper inserts which fit into the bedpan. Solid waste is captured by the paper, which may be pulled out and into the toilet. As the paper is pulled out, the liquid waste is poured out of the handle area. The paper is designed to disperse in water and can be flushed down the toilet along with the waste material. A quick rinsing will clean the bedpan for its next use.




While the preferred embodiments have been shown and described, it will be understood that there is no intent to limit the invention by such disclosure, but rather, the invention is intended to cover all modifications and alternate constructions falling within the spirit and scope of the invention as defined in the appended claims.
