Description
This utility model relates to a kind of contraceptive.
The existing contraceptive that is placed in the uterus is a lot, and it to the effect that can adhere in this utensil such as metal, metal ion, hormone or treat some material of a period of time of working in the uterus with material as on June 29th, 1988 disclosed a kind of＜being placed in the utensil in the uterus〉(application number 87108401) in patent of invention.This utensil has a straight-bar, near or be extended with elasticity or flexible arm at an end of straight-bar to both sides, each end portion of two arms is all curved the angle greater than 90 degree, cause the end portion of two arms to point to this straight-bar, though its weak point has been the arm that extends to both sides of fixation to be curved certain angle but is still had corner angle, therefore also can damage the uterus, make menorrhagia, knee is given in utero to place and is brought difficulty in addition.
In view of being to provide a kind of, above-mentioned weak point the purpose of this utility model of the prior art can reduce vulneratio uteri and the convenient again assembly of intra-uterine contraceptive utensil of placing of stimulation.
The purpose of this utility model can realize by following measure:
A kind of active soft birth control apparatus of the usefulness of practising contraception, it has a straight-bar, be provided with side arm at the front end of straight-bar to the both sides bifurcated, it is characterized in that: this side arm is the plane spiral shape, the through hole that is preferably in the straight-bar tail end is provided with tailfiber, the cross section semicircular in shape of side arm is provided with the electrolysis copper pipe on the outer wall of straight-bar and side arm.
This utility model is the closure birth control apparatus that is made of the set spiral shape side arm of straight-bar and front end both sides thereof.
This utility model mainly is made of straight-bar and side arm two parts.Wherein straight-bar is for having elasticity and flexible cylinder, preferably polyethylene from high pressure process material.Be provided with the side arm that preferably is connected as a single entity that is attached thereto to the both sides bifurcated at its front end.This side arm is the plane spiral shape, and it is the flexible and flexible band material of an apparatus coiled, and it is the polyethylene from high pressure process material preferably.This two side arms can be with uterine contraction, uterine cavity breathing in uterine cavity and strain, and strain is soft, plastic, not only plays the set anticreep but also occupy the anti-implantation of ovum effect of the useful space.The best semicircular in shape in the cross section of this side arm, two side arms lump together becomes a cylinder, so as when laying this birth control apparatus that it is stretching, smoothly by the cervix uteri pipeline.After it arrives at uterine cavity, can launch slowly, be recovered to original spiral shape with pushing ram.Tail end at straight-bar is provided with through hole in addition, is provided with tailfiber in it, is preferably nylon yarn, the usefulness during in order to this contraceptive device of taking-up in uterine cavity.Be preferably on the outer wall of straight-bar and side arm and be with the electrolysis copper pipe, kill spermatozoon, strengthen contraceptive effect so that discharge the copper ion that dissociates.
Drawing is described as follows:
Fig. 1 is a front elevational schematic of the present utility model.
Fig. 2 is the A-A view of Fig. 1.
The utility model is described in further detail to utilize the example shown in the accompanying drawing.In the sketch map of active soft birth control apparatus shown in Figure 1, polyethylene from high pressure process straight-bar 1 front end of once injection moulding is provided with the spiral shape side arm 2 to the both sides bifurcated of the homogeneity that is connected as a single entity with it, and its cross section semicircular in shape as shown in Figure 2.In Fig. 1, on the outer wall of straight-bar and side arm, be provided with electrolysis copper pipe 3 again.Tail end at straight-bar is provided with through hole, is provided with nylon tailfiber 4 in the hole.
The utility model has following advantage compared to existing technology:
Effectively anti-implantation of ovum, contraceptive effect is obvious, lays convenient firmly can not come off, and does not damage and stimulates the uterus, meets the international standard requirement.
