Abstract
The utility model relates to a medical device, particularly a uterine cavity shape intra-uterine device with copper. The utility model comprises a support bracket 1 made of stainless steel in a uterine cavity shape and a spiral copper wire 2 placed in the support bracket 1 made of stainless steel in the uterine cavity shape. The utility model is characterized in that the winding surface of the spiral copper wire 2 is 280 to 320 mm [2]. The utility model has the advantages of simple structure, good contraception effect, etc.
Description
This utility model relates to a kind of medical apparatus and instruments, especially a kind of cupric uterine cavity shaped intrauterine device.
Palace, existing cupric chamber shape intrauterine device generally is that helical form fine copper filament winding group is put into the uterine cavity shaped stainless steel stent, because the copper wire surface area has only 200mm
2, and have only 6 joint copper wire windings, and so its pregnancy rate is still higher, reaches 1 year per hundred women and accumulate pregnancy rate 1.86, influence result of use.
The purpose of this utility model designs exactly that a kind of structure is simple, contraceptive effect is good, the band copper uterine cavity shaped intrauterine device that pregnancy rate with iud is lower.
The purpose of this utility model realizes by following structure; Cupric uterine cavity shaped intrauterine device includes the uterine cavity shaped stainless steel stent and is placed on the interior helical form copper wire of uterine cavity shaped stainless steel stent, and it is characterized in that: helical form copper wire winding surface is 280-320mm
2
This utility model has been owing to suitably increased the surface area of copper, thereby copper ion increases in burst size in utero, more can effectively kill sperm, makes 1 year per hundred women accumulate pregnancy rate and is reduced to 0.44-0.93.
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1. uterine cavity shaped stainless steel stent, 2. helical form copper wire winding, 3. transverse arm is 4. gone up trailing arm, 5. descends trailing arm.
Below in conjunction with drawings and Examples this utility model is further described:
As shown in Figure 1: this utility model includes uterine cavity shaped stainless steel stent 1 and is placed on the interior helical form copper wire 2 of uterine cavity shaped stainless steel stent, and it is characterized in that: helical form copper wire 2 winding surfaces are 280-320mm
2For the copper wire winding can effectively be placed in the stainless steel stent and do not change the profile of stainless steel stent, helical form copper wire winding in the uterine cavity shaped stainless steel stent has more than 7 joints, and two joint helical form copper wire windings are respectively arranged in twice trailing arms 5 of uterine cavity shaped stainless steel stent.
Claims (3)
1. a cupric uterine cavity shaped intrauterine device includes uterine cavity shaped stainless steel stent (1) and is placed on the interior helical form copper wire (2) of uterine cavity shaped stainless steel stent, and it is characterized in that: helical form copper wire (2) winding surface is 280-320mm
2
2. cupric uterine cavity shaped intrauterine device as claimed in claim 1 is characterized in that: the helical form copper wire winding in the uterine cavity shaped stainless steel stent has more than 7 joints.
3. as claim 1,2 described cupric uterine cavity shaped intrauterine device, it is characterized in that: two joint helical form copper wire windings are respectively arranged in twice trailing arms of uterine cavity shaped stainless steel stent (5).
