Abstract

The utility model relates to an intrauterine device, which is a device placed in the uterus to avoid pregnancy. The utility model is processed by adopting a cylinder spiral body wound by stainless steel wires as the main material and the inner part of the cylinder body is poured with an indomethacin rod and a copper rod with certain surface areas and other components after the circular combination and the high-temperature formation. The shape of the intrauterine device is in conformity with the shape of the uterine cavity and the structure is in conformity with the uterine dynamic principle. When the uterine contracts, the intrauterine device moves towards the direction of the uterine bottom without downward movement and disconnection. The inner part of the intrauterine device contains the copper rod whose surface area is 180 mm [2] to increase the effect on avoiding the pregnancy. The utility model also contains the indomethacin medicine rod to play the function for stopping hemorrhage and relieving the pain. Using the intrauterine device can improve the effect on avoiding the pregnancy.

Description

Intrauterine device

The utility model relates to a kind of lady's assembly of intra-uterine contraceptive utensil, more properly say it is to be used to be placed in intrauterine to avoid conceived utensil.

The intrauterine device of clinical practice both at home and abroad is diversified at present, and single steel intrauterine device, Tcu ring, Vcu ring, uterine cavity shaped de-vice, high support force ring etc. are arranged.Although these intrauterine device all can play certain contraceptive effect.But its weak point is the expulsion rate height, and is bigger to the sharp thorn property of the machinery of body of uterus, causes side reactions such as metrorrhagia and pain easily.Influence contraceptive effect and the operation receiveing person is healthy.

The purpose of this utility model is a kind of uterus shape and the uterus principle of dynamics of meeting that designs in order to overcome above-mentioned deficiency, takes simply the intrauterine device that contraceptive effect is good.

This utility model is achieved in that the column type spirillum that it encompasses with stainless steel silk is a material of main part, and longitude circle closes, high-temperature shaping, long-pending copper rod of fill certain surface and anti-inflammatory pain medicine rod etc. process in cylinder.The purpose main points that realize innovation and creation are:

1, the first half shape of this birth control apparatus and uterus cavity bottom shape match, and can effectively alleviate the stimulation of birth control apparatus to cavity of uterus, and increase it in intrauterine stability.

2, the Lower Half of birth control apparatus is a semicircular arc, and its lower edge is suspended from orificium internUm isthmi top, and keeps certain distance.Both sides contact with sidewalls, form the strong point.According to the uterus principle of dynamics, when uterus muscle is shunk, can move to the fundus of uterus direction after birth control apparatus is stressed, and can not move down.Also can not touch cervix uteri internal orifice irritability district, can avoid frequent contraction the in factor palace and other rejections of generation.

3, (surface area is 180mm to the copper rod that includes of birth control apparatus ²) continuous copper ion releasing, can change environment in the cavity of uterus, suppress sperm motility, make it to lose potentia concipiendi.

4, the indometacin pipe rod that includes of birth control apparatus can slowly discharge indometacin, has the antagonism prostaglandin, suppresses uterus muscle contraction and hemostasis, analgesic effect.

This utility model is simple in structure, cost is low, easy to use, side reaction is little, adaptation is wide.Its construction features and contraceptive efficacy all are better than the intrauterine device of other types.

The drawing explanation:

1, stainless steel silk helical body 2, the first half 3, Lower Half

4, copper rod 5, anti-inflammatory pain medicine rod

Claims

1, a kind of column type spirillum that encompasses with stainless steel silk is a material of main part, and through the intrauterine device that the processing typing forms, the structure form that it is characterized in that it is that the first half and uterus cavity bottom shape match, and Lower Half is a semicircular arc.

2,, it is characterized in that the fill surface area is 150mm in the main body spirillum according to the described intrauterine device of claim 1 ²～200mm ²Copper rod, make it by continuous copper ion releasing, increase and to avoid conceived effect.

3, according to the described intrauterine device of claim 1, it is characterized in that fill indometacin pipe rod in the main body spirillum, play and suppress uterine contraction, hemostasis, analgesic effect.
