Abstract

The utility model provides an active intrauterine device, comprising a contraceptive ring and a placement device, characterized in that the contraceptive ring has a shaped and worked elastic ring body, the upper portion of the elastic ring body is in the shape corresponding the arc of the bottom of the uterine cavity while the lower portion of the elastic ring body is shaped as a semi-circle, the placement device comprises a main tube inside of which a guide rod is provided, an elastic fork is arranged on top of the main tube, and a positioning block is disposed on the main tube. The utility model is reasonable in structure and shape, fits the shape and the kinetics of the uterus, reduces the mechanical stimulation and damage to the uterine cavity, and tends not to move or drop off. The placement device if the utility model is simple-structured, convenient to operate, and capable of placing the contraceptive ring into the uterine cavity instantly, thereby shortening the operation time and decreasing the pain of the patient.

Description

Active intrauterine device

Technical field

This utility model relates to a kind of active intrauterine device, belongs to the female contraception utensil.

Background technology

The intrauterine device of clinical practice both at home and abroad has a variety of at present, as metal " O " type ring, Tcu ring, Vcu ring etc., although these intrauterine device all can reach certain contraceptive effect, but because shape and construct unreasonable, cause the expulsion rate height, mechanical stimulus to the uterus is bigger, causes side reactions such as metrorrhagia and pain easily, influences the healthy of contraceptive effect and operation receiveing person.

Goal of the invention

The purpose of this utility model is intended to overcome the weak point that prior art exists, and provides a kind of and meets uterus shape and uterus principle of dynamics, takes the active intrauterine device simple, that contraceptive effect is good.

The technical solution of the utility model is: a kind of active intrauterine device, it comprises intrauterine device and placement device, characteristics are, intrauterine device has the elastic annular body through the processing typing, and the first half of elastic annular body is the arc that matches with the uterus cavity bottom shape, and Lower Half is a semicircular arc, placement device comprises the main body pipe, be movably equipped with guide rod in the main body pipe, the top of main body pipe is provided with the elasticity prong, is provided with locating piece on the main body pipe.

The good effect that compared with the prior art this utility model has is: its intrauterine device first half after the processing typing is the arc that matches with the uterus cavity bottom shape, Lower Half is a semicircular arc, add it and have good elastic performance, when uterus normal condition or contraction, can both adapt to the cavity of uterus form, meet the uterus principle of dynamics, can effectively alleviate mechanical irritation and the damage of intrauterine device, and prevent that effectively intrauterine device from coming off cavity of uterus; Its placement device is simple in structure, and is easy to operate, can insert in the uterine cavity intrauterine device is instantaneous, reduces operating time, reduces patient's misery.

Below in conjunction with drawings and Examples this utility model is done further and to be explained.

Description of drawings

The structural representation of Fig. 1-intrauterine device of the present utility model;

The structural representation of Fig. 2-placement device of the present utility model.

The explanation of accompanying drawing drawing:

1 elastic annular body, 2 main body pipes, 3 guide rods, 4 elasticity prongs, 5 locating pieces, 6 copper rods, 7 medicine rods.

Specific embodiments

Referring to Fig. 1, Fig. 2, intrauterine device adopts elastic metallic material to make, it is an elastic annular body 1, longitude circle closes, behind the high-temperature shaping, the first half of elastic annular body 1 is the shallow arc that matches with the uterus cavity bottom shape, Lower Half is a semicircular arc, and the big I of elastic annular body 1 is made plurality of specifications according to structoure of the human body; Placement device comprises a hollow main body pipe 2, the movable guide rod 3 of installing in the main body pipe 2, and elasticity prong 4 is made on the top of main body pipe 2, and locating piece 5 is installed on the body of main body pipe 2.

During use, the doctor should select the suitable intrauterine device of specification according to the patient's who records the uterine cavity degree of depth, the width and the degree in the wrong that inclines, elder generation embeds the upper limb mid point of the elastic annular body 1 of intrauterine device in the elasticity prong 4 of placement device main body pipe 2, adjust the position of the locating piece 5 on the main body pipe 2 then according to the uterine cavity degree of depth, hand-held main body pipe 2 can be placed in cavity of uterus.When placement device supports at the bottom of the palace, stationary body pipe 2 is motionless, and guide rod 3 is pushed ahead, and intrauterine device can be ejected elasticity prong 4, is placed in the cavity of uterus, withdraws from placement device at last.

The structure form of this intrauterine device meets cavity of uterus form and uterus principle of dynamics very much, and the shallow arcuate shape and the uterus cavity bottom of its first half match, and can effectively alleviate the stimulation of intrauterine device to cavity of uterus, and increases it in intrauterine stability; Lower Half is semicircular arc, and its lower edge is suspended from orificium internUm isthmi top, and keeps certain distance, and both sides contact with sidewalls, forms the strong point.According to the uterus principle of dynamics, when uterine contraction, can move to the fundus of uterus direction after intrauterine device is stressed, and can not move down, can not touch cervix uteri internal orifice irritability district yet, can avoid frequent contraction the in factor palace and other rejections of generation.

The elastic annular body 1 of this utility model intrauterine device can adopt the stainless steel silk serpentine pipe to make, and is not aging, never degenerates, good with human compatibility, no thermal source, no sensitization, and have good deformation behavior.In the stainless steel silk serpentine pipe copper rod 6 can be housed, metal copper ion discharges by stainless steel silk pitch gap, can change environment in the cavity of uterus, suppresses sperm motility and germ cell implantation, reaches contraceptive effect.

The medicine of in the elastic annular body 1 that the stainless steel silk serpentine pipe is made, can also packing into, as indometacin or progestational hormone medicine etc., can directly make medicine rod 7, or put into making the silicone rubber rod behind the silicone rubber admixture medicine, by slow release, have the antagonism prostaglandin, suppress effects such as uterine contraction and hemostasis, pain relieving.
