Abstract
A novel contraceptive ring relates to a birth control equipment, in particular to a intrauterine device. The intrauterine device adopts NiTi memory alloy bent into gamma shape, two silica gel layers (1) are respectively sleeved at two sides of the top ends of the gamma shape, two silica gel layers (2) are respectively sleeved at two sides of the lower middle part of the gamma shape, the outer surface of an internal layer NiTi memory alloy (4) is provided with a copper wire helix tube (3), strip copper area is 200mm<2> to 400mm<2>, the outer surface of the copper wire helix tube (3) is sleevedwith a stainless steel helix tube (5), and the silica gel layers (1) and the silica gel layers (2) are respectively sleeved at the outer surface of the stainless steel helix tube (5). The present invention has the advantages of small side-effect, simple and convenient placing process, and convenient use for basic level medical staffs.
Description
Technical field:
The present invention relates to a kind of family planning articles for use, be specifically related to a kind of intrauterine device.
Background technology:
The intrauterine device of tradition use at present adopts stainless steel silk to be made, and wherein has one section pastille silica gel is arranged, and this intrauterine device in the process more complicated of performing the operation and placing, and causes pain and sense of discomfort to the person of being placed easily.ZL200320122749.0 discloses a kind of active γ type intrauterine device, such intrauterine device, solved the problem in some operation processs, but owing to be provided with the character of copper spiral coil and material itself, cause making by operator being easy to generate stomachache, the soreness of waist, also cause side effect such as intrauterine device comes off easily, moves down.
Summary of the invention:
The purpose of this invention is to provide a kind of novel contraceptive ring, it can alleviate the person's of being placed pain and sense of discomfort, and has simplified the process of operation, and user also is difficult for producing the side effect of stomachache, the soreness of waist.In order to solve the existing problem of background technology, the present invention is by the following technical solutions: it adopts the NiTi memorial alloy to be bent into γ shape, both sides, upper end γ shape are with layer of silica gel 1 respectively, both sides are with layer of silica gel 2 respectively in the middle of the bottom of γ shape, the outside of internal layer NiTi memorial alloy 4 is provided with copper wire serpentine pipe 3, and the band copper face is long-pending to be 200mm
2-400mm
2, copper wire serpentine pipe 3 outsides are with stainless steel silk serpentine pipe 5, and layer of silica gel 1 and layer of silica gel 2 are enclosed within the outside of stainless steel helix tube 5 respectively.The present invention can be fit to the uterus kinetic energy theory, can change along with uterine contraction, allows the almost existence of imperceptible foreign body of layer; Can simplify the process of operation behind application the present invention, reduce the time that operation consumes,, can reduce the person's of being placed misery because the present invention has memory function; Also reduced side effect odds such as stomachache, the soreness of waist, and make the present invention after placement difficult drop-off, move down; The copper face of using among the present invention is rationally long-pending, has reduced cause because copper face is long-pending excessive hemorrhage, can be long-pending not too small because of copper face yet, and cause contraceptive effect to reduce.Side effect of the present invention is little, put procedure is simple and convenient, be convenient to the medical personnel of basic unit uses.Simultaneously, the cost of technology of the present invention and material is all very low, therefore suits large area to popularize more.
Description of drawings:
Fig. 1 is a structural representation of the present invention, and Fig. 2 is the A-A cutaway view of Fig. 1, and Fig. 3 is the B-B cutaway view of Fig. 1.
The specific embodiment:
Referring to Fig. 1-3, this specific embodiment is by the following technical solutions: its adopts NiTi memorial alloy to be bent into γ shape, both sides, upper end γ shape are with layer of silica gel 1 respectively, both sides are with layer of silica gel 2 respectively in the middle of the bottom of γ shape, the outside of internal layer NiTi memorial alloy 4 is provided with copper wire serpentine pipe 3, and the band copper face is long-pending to be 200mm
2-400mm
2, copper wire serpentine pipe 3 outsides are with stainless steel silk serpentine pipe 5, and layer of silica gel 1 and layer of silica gel 2 are enclosed within the outside of stainless steel helix tube 5 respectively.Copper product is that the height of nanometer copper or 99.99% is led copper.Layer of silica gel 1 and layer of silica gel 2 can increase medicines such as containing progesterone or indometacin.Referring to the distance between the two ends of two layer of silica gel 1 in this specific embodiment of Fig. 1 is H1=23-29mm, the distance H 2=8-23mm between two layer of silica gel 2, and the middle part of layer of silica gel 1 is H3=22-28mm to the distance between the bottom.This specific embodiment can be fit to uterus kinetic energy away from, can change along with uterine contraction, allow the almost existence of imperceptible foreign body of layer; Use the process that to simplify operation after this specific embodiment, reduce the time that operation consumes,, can reduce the person's of being placed misery because this specific embodiment has memory function; Also reduced side effect odds such as stomachache, the soreness of waist, and make this specific embodiment after placement difficult drop-off, move down; The copper face of using in this specific embodiment is rationally long-pending, has reduced cause because copper face is long-pending excessive hemorrhage, can be long-pending not too small because of copper face yet, and cause contraceptive effect to reduce.
