Abstract

Claims (18)

1. A method of inserting a reusable menstrual collection device into a vaginal canal, the method comprising:

a) providing a reusable menstrual collection device capable of collecting period fluid, comprising a circumference, a housing that is open at a first end and tapers to a base at a second end from which a stem extends, wherein the housing defines a cavity therein, and wherein the housing comprises includes a frame having a first thickness, wherein the frame comprises two vertical ribs, and wherein the housing further comprises two panels having a second thickness and extending between the frame two vertical ribs, and wherein the housing further comprises a rim extending from the frame to delimit the housing first end;

b) providing a reusable applicator of capable of inserting the menstrual collection device, comprising a housing and a plunger, wherein:

i) the applicator housing comprises a circumference, a sidewall that is delimited at a first end by a tip and a second end by a base, and a first, outer surface, and a second, inner surface, wherein the second surface defining defines a cavity that extends within the housing from the base to the tip;

ii) the applicator plunger is fully separable from the applicator housing and is arrangeable within the cavity of the applicator housing, and wherein the plunger comprises a cylindrical main body that extends between a first end and a second end, the first end including a stem cavity and the second end defined by a plunger base, wherein the stem cavity extends toward the second end, and wherein the plunger base comprises an outer periphery that is greater than an outer periphery of the main body;

iii) the circumference of the menstrual collection device is greater than the circumference of the applicator housing;

c) folding the menstrual collection device to reduce its circumference;

d) loading the first end of the folded menstrual collection device into the applicator housing cavity;

e) arranging the loaded menstrual collection device within the applicator housing cavity such that the stem is in a position to engage with the plunger stem cavity;

f) engaging the plunger stem cavity with the stem and inserting the first end of the plunger into the applicator housing cavity;

g) inserting at least the tip of the applicator housing into a vaginal canal;

h) moving the first end of the plunger towards the tip of the applicator housing such that the menstrual collection device contacts the applicator housing projections;

i) pushing the plunger towards the tip of the applicator housing with a force that causes the housing projections to expand an opening at the tip of the housing of the applicator and allow the folded menstrual collection device to pass through the opening and expand to an unfolded state within the vaginal canal; and

j) retracting the applicator from the vaginal canal.

2. The method of claim 1 , wherein the tip of the applicator includes a plurality of projections that extend in a curved manner from the sidewall toward an apex of the tip and are spaced from each other by gaps that extend into an opening, and wherein the projections comprise rounded edges.

3. The method of claim 1 , wherein the first thickness of the frame is greater than the second thickness of the panels.

4. The method of claim 2 , wherein the projections apply a force on the collection device which translates to the rim thereof, causing the rim to expand from a folded state to a fully open state to create a seal with the vaginal cavity canal.

5. The method of claim 4 , wherein the projections return to an original resting state when no force is applied thereto.
