Abstract

A disposable catamenial device for the collection of menses discharge of the female human, including: a flexible resilient menstrual cup (MC), which includes: at least two resilient ribs extending inwardly from the inner surface of the MC base; an elastic rim frame connected to the top of the ribs; a reservoir bag connected to the rim in a sealed manner for collecting the menstrual fluid; and a withdrawal string connected to the cup bottom for enabling the extraction of said MC from the vagina. The MC has a drogue like structure comprising at least two flexible ribs having arcuate vertical struts (AVS) structure connected to a flat base. The ribs are connected to the elastic rim frame with at least two flexible arcuate horizontal struts (AHS).

Claims

1. A catamenial device configured for the collection of menses discharge of a human female, comprising:

a flexible resilient menstrual cup (MC), comprising;

a rib structure extending from a distal open end of said device toward a proximal end of said device; and

a reservoir bag connected to said rib structure for collecting the menses discharge, said reservoir bag having an open distal end and a proximal end, wherein said reservoir bag proximal end and said rib structure proximal end overlap;

wherein said device has a cylindrical body tapering proximally;

wherein said device is radially symmetric about a central axis, from said device proximal end to said device distal end;

wherein said MC has a port about the central axis at said device distal end, said rib structure configured to seal said device distal end at said port to a vaginal cavity of the human female, at a location along the vaginal cavity which is remote from the cervix.

2. The device according to claim 1, wherein said rib structure resilient structure and elasticity enables said MC to be positioned within the vaginal cavity in a sealed manner such that said MC comprising the collected fluid is held inside the vaginal cavity.

3. The device according to claim 1, wherein said rib structure has one of a parallel structure, a vertical structure, and an elongate structure.

4. The device according to claim 1, wherein said reservoir bag includes a thin membrane which is made from elastic or non-elastic material.

5. The device according to claim 1, additionally comprising at least one absorbent element located along walls of said reservoir bag, said at least one absorbent element configured to prevent spill and leakage during extraction of said MC.

6. The device according to claim 1, wherein said at least one absorbent element is made from absorbing material selected from a group consisting of:

natural fibers, synthetic fibers, fluff pulp, needle-punched engineered absorbents, fiber tows, tow webs, cellulosic sponge materials, superabsorbent materials, materials which forms a gel upon contact with moisture, and combinations thereof.

7. The device according to claim 1, wherein said device complies with at least one of FDA regulations pertaining to Obstetrical and Gynecological Devices;

FDA class II performance standards; and

FDA biocompatibility standards for prevention of adverse tissue reaction.

8. The device according to claim 1, wherein said rib structure is configured to collapse into the applicator.

9. The device according to claim 1, wherein said rib structure includes biodegradable materials.

10. The device according to claim 1, wherein said MC has a drogue-like structure such that it allows deployment within the vaginal cavity and resists inadvertent retraction from within the vaginal cavity.

11. The device according to claim 1, wherein said MC has one of a cone-like structure, an umbrella-like structure, and a combination thereof.

12. The device according to claim 1, wherein said rib structure includes at least a sine-shaped rib.

13. The device according to claim 1, further comprising an elastic rim frame connected to said rib structure at a distal end of said device, said elastic rim frame including one of at least two flexible arcuate struts and at least two circumferentially arranged struts.

14. The device according to claim 1, wherein said reservoir bag is connected to said elastic rim frame.

15. The device according to claim 1, wherein said device is disposable.

16. The device according to claim 1, wherein said central axis is configured to be coincidental with a vaginal axis of the female human.

17. The device according to claim 1, wherein said rib structure includes a plurality of ribs, all of said ribs being convex.

18. The device according to claim 1, wherein said rib structure includes a plurality of ribs, all of said ribs having a same shape and length.

19. The device according to claim 1, wherein said rib structure includes a plurality of ribs, all of said ribs being curved and being parallel to each other at their distal ends.

20. The device according to claim 1, wherein said rib structure is outwardly resilient when in a resting state.

21. The device according to claim 1, wherein said port is configured to seal said device at a vaginal passageway leading to the cervix, at a distance from the cervix.

22. The device according to claim 1, wherein said port is configured to seal said device against inner walls of a vaginal passageway, at a location along the vaginal passageway which is remote from a cervix.

23. The device according to claim 1, wherein said rib structure includes a plurality of ribs connected to each other in an arch shape.

24. The device according to claim 1, wherein said rib structure is configured to open said MC into a cup shape.

25. The device according to claim 1, wherein said device terminates in said port at said device distal end, said port configured to seal said device distal end to the vaginal cavity of the human female.

26. The device according to claim 1, wherein said rib structure central axis is configured to be coincidental with a central axis of the vaginal cavity.

27. The device according to claim 1, wherein said device distal end is an elastic rim of said device.

28. The device according to claim 1, wherein said rib structure is configured to apply forces at said device distal end, wherein said forces are evenly distributed about said device distal end.

29. The device according to claim 1, wherein said rib structure includes ribs which have a parallel structure along at least a portion of said ribs.

30. The device according to claim 1, wherein said MC does not narrow from said device distal end to said device proximal end.

31. The device according to claim 1, wherein said rib structure is radially symmetric about a central axis, from said device proximal end to said device distal end.

32. The device according to claim 1, wherein said device distal open end is perpendicular to the central axis.
