The present invention relates generally to reusable feminine hygiene products and their use in managing menstruation, and more specifically, to features that improve the insertion/removal process, improve sanitation, and improve overall comfort and ease of use during the removal and disposal of blood as well as reduce environmental waste.
Menstrual cups and discs are a relatively unadopted technology in the space of feminine hygiene and menstruation products when compared to other menstrual devices. Menstrual cup technology itself has been around since the 1930's and menstrual discs since the 1990's, and despite the cost saving advantage and environmental benefits of reusability, they have yet to receive widespread adoption. The reasons for this may include lack of education or habit in behavior, but there are also concerns related to ease of use and sanitation that may affect adoption. Traditional menstrual cups and discs must be inserted and removed through the insertion of the hands into the vaginal canal every time the device needs to be emptied. While there are differences between menstrual cups and discs, the primary mechanism of fixing the device into place in the vaginal canal to collect blood in a reservoir is common between them.
In the case of menstrual cups, the device is folded, inserted and allowed to expand, creating suction against the vaginal canal allowing the reservoir to collect menstrual blood without slipping. This suction comes at the cost of difficulty in removal. While many menstrual cups come with handles or grip at the bottom of the cup, most users of these cups will not be able to simply pull the cups out easily as the suction can make it difficult. Many menstrual cup users report pain or discomfort when pulling against the suction and instead reach into the vaginal canal to pinch the cup and break the suction before removing. The removal techniques of the cup often lead to unsanitary insertion of the hands and difficulty in extraction that may lead to mess in the spilling of menstrual blood from the cup. The main complaints of users tend to focus around discomfort, difficulty in removal, frequency of removal and reinsertion as well mess from spilling menstrual blood and other sanitation concerns.
In the case of menstrual discs, the device is inserted further into the vaginal canal than menstrual cups and rests near to the cervix. The elastically flexible but firm rim fits snugly against the vaginal fornix between the pubic bone and posterior fornix where the open mouth of the reservoir faces the cervix and collects blood. Menstrual discs do not create suction and thus do not share the discomfort of resistance provided by the suction force during extraction. The main complaints of menstrual discs generally relate to difficulty in insertion, mess and difficulty during extraction, as well as instability of the device during the menstrual cycle. As menstrual discs are positioned near the cervix, the device requires that the user insert their hands far deeper into the vaginal canal to insert and remove the device. The device is fixed in place by maneuvering it to fit snugly against the vaginal fornix which may prove difficult for users to reach during the removal process and often result in mess and unsanitary practices.
Many users of menstrual discs report that it is nearly impossible to remove a disc full of menstrual blood without spilling on the hands or elsewhere. Also, as the device must fit near to the cervix against the vaginal fornix, the reservoir portion of the device is disc shaped rather than cup shaped and is generally of a lower capacity than menstrual cup and disposable absorbent technologies, requiring that the user remove and empty the disc more often than they might like to.
The present invention attempts to solve the problems associated with both menstrual cups and discs as well as others.
Provided herein are systems, methods and apparatuses for a Menstrual Reservoir with Valvular Outlet. In one embodiment, the Menstrual Reservoir with Valvular Outlet comprises a flexible and elastic reservoir herein referred to as “the reservoir portion” of the device. The reservoir portion has at least one outlet, herein referred to as “the reservoir outlet portion” of the device. The reservoir outlet portion may be but is not limited to a hole or tubular structure of any length, preferably leading to the vaginal opening. The flow of blood through the reservoir outlet portion is controlled by at least one valve, herein referred to as “the valvular portion” of the device. The valvular portion comprises at least one inlet or inlet portion, at least one valve mechanism and at least one outlet or outlet portion. When the the valvular portion is in a closed configuration, flow is arrested and the reservoir portion and reservoir outlet portion serve as a cavity to collect menstrual blood; when the valvular portion is in an open configuration, flow is allowed and the reservoir outlet portion serves to drain menstrual blood from the reservoir out of the vaginal canal through the valvular outlet portion. When the valvular portion is in an open configuration, air is allowed to flow into the reservoir through the outlet portion, both displacing the collected menstrual blood and after emptying the reservoir, releasing suction force if present.
The mechanism of the valvular portion may refer to any process either mechanical or electrical which may selectively arrest or allow the flow of fluid, this may comprise of but is not limited to the following: ball valves, pinch valves, clamp valves, twist control valves, shutter valves, push/pull valves, button valves, mechanical valvular mechanisms of any kind, solenoid valves, electrostatic valves, electrical/magnetic valves of any kind, removable end caps or removable/movable/switchable obstructions to the outlet portion of any kind, zippers, fasteners, interlocking sections, joints, plungers, syringes, pressurized tubes, extraction devices, or any other mechanism in which the reservoir may be selectively drained allowing for the removal of collected blood without the removal of the Menstrual Reservoir from the vaginal canal.
In various embodiments, the valvular portion may be permanently fixed to the reservoir outlet portion or it may be detachable, either for ease of use, ease of cleaning, ease of storage or for any other reason. The valvular portion of the device may function either through a mechanism that remains attached to the reservoir as it is collecting menstruation in the vaginal canal, or it may function as a device that is disconnected from the main reservoir until it is attached to the main reservoir when the reservoir is to be drained.
In one embodiment in which the reservoir portion is a menstrual cup, a method for using the Menstrual Reservoir with Valvular Outlet comprises: setting the valvular portion of the device to a closed configuration, folding the reservoir portion of the device to a folded configuration of diameter D3 from an unfolded configuration of diameter D1 and inserting the diameter D3 of the folded configuration into the vaginal canal towards the cervical opening; as the device is inserted, the flexible cup portion will expand to a partially folded configuration of diameter D2 and then return to a fully unfolded configuration of diameter D1; with a small amount of rotational adjustment, the rim of the reservoir portion will create a suction force sealing the device in the vaginal canal with the open mouth of the reservoir portion facing the cervix; the reservoir will then collect menstrual blood during the menstruation cycle until the reservoir is sufficiently full and in need of draining; the reservoir portion may then be drained by setting the valvular portion of the device to an open configuration; air will flow into the reservoir from the outlet portion and the blood will flow from the reservoir through the outlet portion and exit the vaginal canal. After blood has drained, the valvular portion may then be left in an open configuration and by pulling on the reservoir outlet or valvular portion, air is allowed to enter the reservoir and release the suction force allowing for easy extraction of the device. The device may then be cleaned, sanitized and the process repeated until menstruation has ceased. The device may be used in subsequent menstruation cycles in the same fashion.
Alternatively, in another method, after insertion and menstruation, once the reservoir is sufficiently full, the valvular portion may be opened and the reservoir only partially drained; the air entering the reservoir will only displace the blood expelled from the outlet and suction will be preserved; the valvular portion may then be closed and the device may be left inside the vaginal canal; the reservoir may then be drained partially as it refills with new menstruation in a repeated fashion until menstruation has ceased; the device may then be removed, cleaned and sanitized and reused in subsequent menstruation cycles.
In another embodiment in which the reservoir is a menstrual disc, a method of using the Menstrual Reservoir with Valvular Outlet comprises: setting the valvular portion of the device to a closed configuration, pinching the rim of the reservoir into a pinched configuration, inserting the pinched reservoir into the vagina as far back as can be achieved, flipping the reservoir and tucking the front rim of the reservoir behind the pubic bone in the vaginal fornix with the open mouth of the reservoir facing the cervix. After allowing menstruation to occur for a certain period of time, the reservoir may then be drained by setting the valvular portion of the device to an open configuration allowing blood to drain from the reservoir. As the device is held in place by fitting against the vaginal fornix, there is no suction force that can be released, so the user may allow the reservoir to drain fully without worry of the device falling out of place. The user may then set the valvular portion to a closed configuration and repeat the cycle of allowing menstruation to collect before draining. Once menstruation has ceased, the end user may then set the valve to an open configuration and remove the device either by reaching in to grab the reservoir, or by pulling on the valvular portion or reservoir outlet portion, causing flexion of the reservoir rim and extraction of the device.

Generally speaking, the Menstrual Reservoir with Valvular Outlet is a reusable feminine hygiene product and the method of using the Menstrual Reservoir with Valvular Outlet is for managing menstruation, and more specifically, to features that improve/speed up the insertion and removal process, improve/speed up the process of disposing blood, improve capacity/wear time, reduce mess/cleanup, reduce unsanitary hygiene practices, improve the period experience in general and reduce environmental waste.
The Menstrual Reservoir with Valvular Outlet is a simple, reusable alternative to menstrual pads, sanitary napkins, tampons, and disposable undergarments as well as preexisting reusable menstrual devices, such as menstrual cups, discs or washable undergarments. The Menstrual Reservoir with Valvular Outlet may in some ways be considered as an intended improvement to existing menstrual cup, menstrual disc and other menstrual reservoir technologies in market today.
The Menstrual Reservoir with Valvular Outlet comprises a reservoir portion facing towards the cervical opening. The reservoir portion may vary significantly in various embodiments and may be fixed in place similar to preexisting menstrual cups or preexisting menstrual discs. According to various embodiments, the reservoir is flexible and provides a method for easy insertion and may be able to create suction in the vaginal canal upon expansion or it may be fixed in place through resting against the vaginal fornix near the cervix. After fixed in place, the reservoir serves to collect the flow of menstruation exiting from the cervix into the vaginal canal. The reservoir cup comprises a diameter and rim height specifically selected based on the anatomical features of the female body. Pelvic floor strength (influenced by age, childbirth, weight and muscularity among other factors), cervix height (accounting for both baseline cervix height and changes that may occur during the menstrual cycle) and fluid capacity are all size, property and dimension considerations for the Menstrual Reservoir with Valvular Outlet.
The various embodiments of the Menstrual Reservoir with Valvular Outlet will fall into two main categories: Menstrual Cup embodiments and Menstrual Disc embodiments; what differs between these embodiments is the method in which the device is fixed into place in the vaginal canal: in the case of menstrual cup embodiments, the device is fixed into place through a suction force in the vaginal canal caused through reservoir expansion, in the case of menstrual disc embodiments, the device is fixed in place by fitting against the vaginal fornix between the pubic bone and posterior fornix. What is common between all embodiments is a reservoir portion facing the cervical opening designed to catch menstrual fluid exiting the cervix and a method for fixing the device in the vaginal canal.
The following description and accompanying figures will focus on the Menstrual Cup embodiment category of the Menstrual Reservoir with Valvular Outlet followed by a shorter description of a Menstrual Disc embodiment of the device with some accompanying figures. There are far more similarities than differences between the two embodiment categories, as the main distinction between the two is related to insertion/removal, as well as difference in the forces holding the device in place. The novelty and improvement in mechanism provided by the Menstrual Reservoir with Valvular Outlet is common between Menstrual Cup embodiments and Menstrual Disc embodiments and differs only in the effect it has on the suction force of Menstrual cup embodiments. The primary improvements offered by the Menstrual Cup with Valvular Outlet are in the ease of controlled drainage of fluid from the reservoir, a substantial increase of wear time without need of extraction, as well enabling extraction of the device without needing to insert hands into the vaginal canal. These improvements are common between both menstrual cup and menstrual disc embodiments.
The material selected for the reservoir portion may vary between very flexible/elastic, flexible/elastic, somewhat flexible/elastic, somewhat rigid/elastic and rigid/elastic, as long as the device is able to be inserted comfortably and the device may be able to be fixed in the vaginal canal, the material flexibility of the reservoir may vary significantly. The reservoir portion comprises a rim near the opening of the reservoir cup nearest to the cervix. This rim may be a similar diameter as the main body of the reservoir cup, but it is preferably of a slightly larger diameter to assist in creating a seal for the suction force against the vaginal canal. As shown in
As show in
The reservoir portion comprises a reservoir outlet portion allowing for the drainage of fluid from the main body of the reservoir. The reservoir outlet portion comprises at least one opening of the main reservoir body. In one embodiment, as shown in
The reservoir outlet entrance 8 and reservoir outlet tube 6 may both be considered collectively as the primary components of the reservoir outlet. The reservoir outlet may be made of a material identical to the main reservoir body, but it may also be made of a material comprising different properties of rigidity, flexibility, elasticity, or any other aesthetic or material quality. The reservoir outlet does not have the same constraints of flexibility/elasticity as the main reservoir body, and may range from very flexible to fully rigid. The relative flexibility/elasticity of the main body and rim of the reservoir is necessary to provide the mechanism of creating suction in the vaginal canal. The reservoir outlet does not necessarily need to contribute to the creation of suction through the displacement of air, and may be considered as primarily and inlet for air into the reservoir and outlet for fluid from the reservoir. The material properties of the reservoir outlet may vary significantly in various embodiments, but common to all embodiments, the reservoir outlet must allow for the drainage of fluid from the main reservoir body. The reservoir outlet may be fixed to the main reservoir body by any number of means or processes and may vary significantly between different embodiments, but common to all embodiments, the reservoir outlet will comprise an air tight seal in which the main reservoir body and reservoir outlet may be considered as fused and both considered as primary components of the reservoir.
Embodiments of reservoir outlet portions may be permanently fixed to the main reservoir body, or may be able to be detached/removed from the main reservoir body either to assist in cleaning/sanitation, make the device more compact for storage or any other reason. The reservoir outlet may comprise any length of material and vary from an opening without length to a long reservoir outlet.
The reservoir outlet portion is controlled by a valvular portion. The valvular portion comprises an inlet portion, mechanism and outlet portion. The valvular portion serves to selectively arrest and allow the flow of liquid according to manually controlled or automated mechanism. The valvular portion may be located anywhere along the reservoir outlet portion or even extend into the reservoir body itself. The valvular portion may comprise any number of mechanisms, both mechanical and electrical as long as it allows selective control of fluid drainage from the reservoir outlet. The valvular portion can be set to an “open” state or “closed” state; when in an “open” state, the valvular portion allows fluid to flow through the reservoir outlet; when in a “closed” state, the valvular portion prevents fluid from flowing through the reservoir outlet.
As shown in
As shown in

As shown in
In one embodiment, a method for the use of the device is as follows: The user of the device either prior to menstruation has begun or when menstruation has begun will set the valvular portion of the device into a closed configuration as shown in
The user will then be free to pursue other activities as their menstruation progresses for a given period of time. This period of time may vary upon different factors such as reservoir size or rate of flow. After a sufficient period of time has past, the reservoir will collect enough blood to be considered as in a “full” state, as shown in
In one method, herein referred to as Method A, the user may allow the fluid to fully drain from the reservoir and reservoir outlet and the reservoir may be considered to be in an “empty” state. When the device is in an empty state, additional air that flows into the main reservoir body will no longer displace blood as there is no more blood left in the reservoir. The user may then pull on the valvular outlet portion of the device, and as the device is drawn against the narrowing vaginal canal, this will cause the device to enter a pinched configuration of diameter D2 as shown in
In another method, herein referred to as Method B, after the reservoir has entered a draining state, the user may elect to close the valvular mechanism prior to the reservoir entering an empty state. This will maintain the suction force keeping the reservoir in place as the total volume of air entering the reservoir from the valvular outlet will equal the displaced volume of blood draining from the valvular outlet. This method will allow the user to leave the device inserted and repeat the process of partially draining the reservoir until menstruation has ceased when the device may finally be removed in a fashion identical to Method A. So concludes the detailed description of various design embodiments and various methods of operation relating to a Menstrual Cup embodiment of the Menstrual Reservoir with Valvular Outlet.
As aforementioned, the Menstrual Reservoir with Valvular Outlet may too have any number of Menstrual Disc embodiments. The primary difference between Menstrual Disc embodiments and Menstrual Cup embodiments is in the insertion/removal process, as well as the relationship the reservoir outlet portion and valvular portion have with suction forces in the reservoir portion. In Menstrual Disc embodiments, the reservoir is positioned much nearer to the cervix than in Menstrual Cup embodiments and is not held in place by a suction force, instead, in Menstrual Disc embodiments the reservoir is held in place by the rim of the reservoir fitting against the vaginal fornix between the pubic bone and posterior fornix. There is no air tight seal of the reservoir in Menstrual Disc embodiments as there are in Menstrual Cup embodiments. What is common between Menstrual Cup and Menstrual Disc embodiments is the function of the valvular mechanism in regards to the drainage of fluid from the reservoir portion through the reservoir outlet portion. As is shown in
The device and hands are the end user are washed and sanitized. The valvular portion of the device is set to a closed configuration. As shown in
In both embodiment categories of menstrual cups and menstrual discs, the addition of a reservoir outlet and valvular mechanism greatly enhances the time in which the device can be left in the vaginal canal, greatly reduces the potential for mess in the spilling of menstrual blood, greatly improves sanitation by reducing the amount of time in which potentially unsanitary hands must be inserted into the vaginal canal, and greatly improves the ease and comfort of extracting the device from the vaginal canal. The innovation while differing slightly in menstrual disc and menstrual cup embodiments are of such similar nature they may both be considered as benefiting from the same innovation, namely the Menstrual Reservoir with Valvular Outlet.
The methods, drawings, diagrams, embodiments and examples mentioned in this detailed description are not meant to be interpreted as restricting or as limited to the inventive device or its intended use, but are merely intended to be illustrative of the device and potential methods of operation.
