Abstract
A T-shaped intrauterine contraceptive device is composed of a wire, a downwards recessed semi-cylinder transverse arm, a silicon rubber medicine bar containing indomethacin, a copper bush and a tail stopper. The copper bush, the silicon rubber medicine bar containing the indomethacin and the tail stopper are hung in the middle of the downwards recessed semi-cylinder transverse arm through the wire, and the diameter of a cylinder formed by closing two sides of the transverse arm together is equal to that of the copper bush below the transverse arm. The T-shaped intrauterine contraceptive device is reasonable in design and capable of reducing bleeding and cervical dilation proportions, saving troubles of operating surgeons, relieving pains of a recipient who undergoes an operation and decreasing possibilities of coming off of the intrauterine contraceptive device. The superficial area of copper is high in use rate, continuation rate after the intrauterine contraceptive device is mounted is increased and acceptability of the operating surgeons and the recipient who undergoes the operation is improved, so that development of family planning work is favored.
Description
Technical field
This utility model relates to a kind of intrauterine device that is used for family planning, particularly a kind of T type intrauterine device.
Background technology
China is that intrauterine device uses big country, and up to now, existing nearly 200,000,000 women of China use intrauterine device, account for the world and use intrauterine device crowd's 3/4ths.T type intrauterine device is a wherein topmost class.Existing T type intrauterine device has following deficiency:
1, trailing arm is made of plastics, and certain degree of hardness is arranged, and compliance is relatively poor during uterine contraction, easily causes bleeding;
2, transverse arm has two kinds, and for plastics are made, one is a cylinder, and its middle part links to each other with trailing arm; During placement, transverse arm is inwardly pressed close to trailing arm downwards, the unification of three cylindrical body, and volume increases, and has strengthened the difficulty of placement of intrauterine devices, and the doctor places needs the expansion cervix mouth often, bothers, and during the expansion cervix mouth, the person of undergoing surgery has certain misery; It two is the recessed semicylinder in middle part, recessed bottom links to each other with trailing arm, during placement, it is a cylinder that transverse arm upwards closes up, but the cylindric trailing arm that normally is wound with copper wire that transverse arm matches therewith, the cylindrical diameter that its diameter forms than the transverse arm on it wants big, has irrational problem in the design.
3, the active matter copper sheathing of trailing arm and its outer wrapping contact closely, the internal surface area of copper sheathing is not utilized, and has reduced the contact surface of copper surface area and uterine fluid, the efficient that copper ion discharges is lower.
4, adding the medicine indomethacin that reduces bleeding side reaction in the birth control apparatus, is current a kind of new tool to reduce hemorrhage.
Summary of the invention
In order to improve the compliance of intrauterine device trailing arm when the uterine contraction, reduce bleeding side reaction; Reduce the ratio that expands the palace when placing, reduce the misery of surgical object and make things convenient for operator; Improve the utilization rate of copper sheathing surface area, this utility model provides a kind of T type intrauterine device.
The technical solution of the utility model is: T type intrauterine device is made up of filament, up concave type semicylinder transverse arm, the silicone rubber medicated strip that contains indomethacin, copper sheathing, tail plug, copper sheathing, the silicone rubber medicated strip that contains indomethacin and tail plug is suspended on the middle part of up concave type semicylinder transverse arm with filament.Up concave type semicylinder transverse arm upwards closes up formed cylindrical diameter, and is big with the diameter of copper sheathing under it etc.
The beneficial effects of the utility model are: reasonable in design, the soft trailing arm of formation has added the medicine indomethacin that reduces bleeding side reaction, and is good to uterotonic compliance, can reduce hemorrhage; The diameter etc. that closes up formed transverse arm and the trailing arm under it during placement is big, and volume is less, has reduced the ratio that expands the palace, has reduced the trouble of operative doctor, has alleviated operation receiver's misery; Save copper material, alleviated deadweight, can reduce the probability that comes off; Copper surface area utilization rate height; Based on above advantage, this birth control apparatus can improve the continuation rate after the placement, but can improve operative doctor and operation receiver's acceptance, helps carrying out of family planning work.
Description of drawings
Fig. 1 is the assembling sketch map of the outstanding arm type of this utility model.
Among the figure, 1, filament 2, copper sheathing 3, the silicone rubber medicated strip 4 that contains indomethacin, tail plug 5, up concave type semicylinder transverse arm.
The specific embodiment
With reference to Fig. 1, filament (1), pass the aperture at up concave type semicylinder transverse arm (5) middle part, on filament (1), be with copper sheathing (2), the silicone rubber medicated strip (3) that will contain indomethacin inserts in the copper sheathing (2), copper sheathing (2) under tail plug (4) is filled in, reuse filament (1) forms in the knotting of the bottom of tail plug (4).
Claims (2)
1. T type intrauterine device, form by filament, up concave type semicylinder transverse arm, the silicone rubber medicated strip that contains indomethacin, copper sheathing, tail plug, it is characterized in that: the middle part that copper sheathing, the silicone rubber medicated strip that contains indomethacin and tail plug is suspended on up concave type semicylinder transverse arm with filament.
2. have as right and ask the Novel T-shaped intrauterine device described in 1, it is characterized in that: up concave type semicylinder transverse arm upwards closes up formed cylindrical diameter, and is big with the diameter of copper sheathing under it etc.
