Abstract

The utility model relates to a contraceptive apparatus, in particular to a contraceptive device for longitudinally and transversely uniformly releasing medicaments. The contraceptive device can longitudinally and transversely uniformly distribute and release the medicaments in an uterine cavity so as to add the action of flexible protection and improve the distributing uniformity of contraceptive medicaments in the uterine cavity while ensuring the contraceptive effect to avoid the side effects brought by rigid scratching inflammation and local over-rich medicaments. The utility model comprises a V-shaped framework (1), a transverse pulling line (2) and a medicated high-molecular material pipe (3), wherein the V-shaped framework (1) is made of a memory alloy wire, the medicated high-molecular material pipe (3) is sleeved on and penetrates through the two lateral arms of the framework (1) and the transverse pulling line (2), and the transverse pulling line (2) is made of a medical high-molecular material, connected between the two end rings of the framework (1) and bonded and fixed through a medical adhesive or vulcanized in the rings through silicon rubber.

Description

A kind of birth control apparatus of equal release thing in length and breadth

Technical field

This utility model relates to a kind of contraceptive device, particularly relates to a kind of birth control apparatus that can evenly discharge medicine in uterine cavity in length and breadth.

Background technology

Though contraceptive effect is better mostly for medicated intrauterine devices, but still have 2 deficiencies: the first adopt more rigidity and (or) semi-rigid material, directly use as copper, plastics, rustless steel and marmem etc., though they have destroyed the implantation environment of germ cell, but it easily produces friction, damaged and inflammation to the tender uterine cavity mucosa in surface in the process of relaxing is contracted in the uterus; It two is drug release skewness, and particularly some medicine is more concentrated, and local concentration is excessive, is prone to side effect.

Summary of the invention

This utility model provides a kind of birth control apparatus of equal release thing in length and breadth, and purpose is to overcome the above-mentioned shortcoming that existing medicated intrauterine devices exists, and is guaranteeing contraceptive effect De Tong Time, pays attention to human oriented design, protects tender inner membrane of uterine cavity; Simultaneously, with the uniform as far as possible release of contraceptive, in order to avoid bring out all female diseases, special proposition is a kind of simple in structure, difficult drop-off, the new intrauterine devices care of uniform slow release or controlled release drug.

Above-mentioned purpose of the present utility model is achieved in that accompanying drawings is as follows:

A kind of birth control apparatus of equal release thing in length and breadth, it is made V-arrangement skeleton 1, cross bracing wire 2 by memory alloy wire and overlaps the pastille macromolecular material pipe 3 that is through on skeleton 1 two side arms and the cross bracing wire 2 and form, described cross bracing wire 2 adopts medical macromolecular materials, be connected between the skeleton 1 two ends annulus, and with medical adhesive dressing knot fixing or with silicon rubber vulcanization within annulus.

The memorial alloy filament diameter Ф of described skeleton 1 is 0.3-0.6mm, and two ends bends to annulus to the symmetrical centre direction respectively, and two Side arm angle α are 20 °-40 °, and angle of splay β is 115 °-165 °, and the birth control apparatus height H is 20-40mm, and width W is 30-50mm.

Described pastille macromolecular material pipe (3) is a hollow circular-tube.

Intrauterine device of the present utility model has multiple advantage:

The first, structure and technology are simple, are easy to give birth to wide.The second, an iron hand in a velvet glove, both be difficult for coming off, do not abrade inner membrane of uterine cavity again.Three, drug distribution is even, reduces toxic and side effects.Four, be easy to broadcast and take out.

Description of drawings

Fig. 1 is this utility model structural representation of equal release thing birth control apparatus in length and breadth.

Wherein: 1.V shape skeleton 2. cross bracing wires 3. pastille macromolecular material pipes

The specific embodiment

Below the embodiment that provides with regard to accompanying drawing this utility model structure made further Details describe in detail bright.

Of the present utility model a kind of can be in uterine cavity equal birth control apparatus of release thing in length and breadth, be to make skeleton 1, cross bracing wire 2, and the pastille macromolecular material pipe 3 that cover is through on skeleton 1 two side arms and the cross bracing wire 2 is formed by memory alloy wire.Pastille macromolecular material pipe 3 can all have medicine slow release or controlled release drug in uterine cavity equably at vertical and horizontal, and holds concurrently inner membrane of uterine cavity is carried out flexible protective, makes it to be difficult for being scratched.

Wherein, the memorial alloy filament diameter Ф of skeleton 1 is 0.3-0.6mm, and two ends bends to annulus to the symmetrical centre direction respectively, and two Side arm angle α are 20 °-40 °, and angle of splay β is 115 °-165 °, and the birth control apparatus height H is 20-40mm, and width W is 30-50mm;

Cross bracing wire 2 adopts medical macromolecular materials, be connected between the skeleton 1 two ends annulus, and with the medical adhesive dressing knot fixing or with silicon rubber vulcanization within annulus;

Contraceptive such as levonorgestrel, gestodene are carried in silicone rubber, polyurethane or the EVA macromolecular material, make hollow circular-tube 3 again, and cover is through on skeleton 1 two side arms and the cross bracing wire 2, promptly become in length and breadth all intrauterine device of release thing.

With reference to Fig. 1, a kind of birth control apparatus of equal release thing in length and breadth, the memorial alloy filament diameter of getting skeleton 1 is 0.45mm, design high-temperature phase-change point is 12 degree Celsius for 33 degree low temperature phase change points Celsius, two Side arm angle α of skeleton 1 are 30 °, it is the 2.5mm annulus that two ends bends to diameter to the symmetrical centre direction respectively, angle of splay β is 135 °, h1 is 25mm, and h2 is 8mm, and the birth control apparatus height H is 30mm, width W is 40mm, pass through die forming then, fixing, and finalize the design and the shape memory heat treatment, thereby obtain having super-elasticity and the suitable shape-memory alloy wire skeleton 1 of serviceability.

The silicon rubber hose 3 that reuse contains contraceptives such as levonorgestrel, gestodene overlaps the two side arms that is through skeleton 1; Medical operation suture thread 2 is also covered one section silicon rubber hose 3 that contains contraceptive, two ends are connected between A point and the B point, and with the A point and the B point bonding is fixed or with silicon rubber vulcanization within the two ends annulus, so far just finished this utility model equal manufacturing process of release thing birth control apparatus in length and breadth.
