An intravaginal device with a tubular body
The tubular body
A vagina that has a larger diameter or cross-sectional area than the vaginal canal and is the outer surface on which the tubular body can be pressed against the tissue wall of the vaginal canal and into the vaginal cavity around the opening of the cervix. Has an outer surface to secure the inner device,
The first part, which defines the first depression to collect ejaculation during sexual intercourse,
The second part, which defines the second depression that passes the ejaculatory fluid to the outer mouth of the cervix,
Includes a flow path defined by the inner surface of the tubular body extending between the first and second recesses, the flow path where pressure is repeatedly applied to the first portion and / or the outer surface during sexual intercourse. When added , an intravaginal device configured such that the ejaculatory fluid travels from the first depression to the second depression and is passed to the extrauterine ostium of the cervix. The outer surface of the tubular body
The intravaginal device according to claim 1, wherein the vaginal device has a shape including a linear shape, a cylindrical shape, a rectangular prism shape, a tapered shape, a convex shape, or an asymmetrical shape, and has a shape that engages with the tissue wall of the vaginal canal. The intravaginal device according to claim 1, wherein the second depression has a size so as to surround the outer mouth of the cervix. The vaginal device according to claim 1, wherein the outer surface is configured to surround the first and second depressions and the flow path so that the ejaculatory fluid is not exposed to the vaginal environment. The intravaginal device of claim 1, further comprising folds defined along the inner surface defining the flow path, wherein the folds prevent the ejaculatory fluid from flowing back toward the first depression. .. The fold is one of a plurality of folds defined along the inner surface, and the plurality of folds sprinkle the ejaculatory fluid each time pressure is applied to the vicinity of the first recess of the tubular body. The intravaginal device of claim 5 , which is stepwise along the flow path. The vagina according to claim 1, further comprising a valve located proximal to the first recess, which is configured to allow fluid flow to pass by opening due to a predetermined pressure gradient generated over the valve. Inside device. The intravaginal device of claim 1, wherein the outer surface defines the concave or tapered cylindrical first portion and the hemispherical second portion. The intravaginal device of claim 1, wherein the second recess comprises a gasket having a size surrounding the outer mouth. The second portion of the tubular body comprises a plurality of conduits defining the plurality of compartments so that the plurality of compartments extend outward when pressure is applied near the first recess of the tubular body. The intravaginal device according to claim 1, which is configured. The tubular body further comprises an elastic zone configured near the first recess of the tubular body to deform when pressure is applied along the longitudinal axis of the intravaginal device, the second portion. The intravaginal device according to claim 1, which is tilted at an angle of at least 15 degrees with respect to the elastic zone and a horizontal axis substantially orthogonal to the vertical axis. The intravaginal device of claim 1, further comprising a string at both ends attached to the first and second portions of the tubular body. Further provided with one or more folds defined along the outer surface of the tubular body, the folds are prone to partial collapse of the tubular body when pressure is applied near the first recess of the tubular body. The intravaginal device according to claim 1. The intravaginal device of claim 1 , wherein the flow path comprises an extensible chamber located proximal to the valve . The intravaginal device of claim 1 , wherein the tubular body is at least 1.5 inches long and 3 inches or less in length.
