Description

A kind of apparatus that stops very early pregnancy

This utility model is about the family planning apparatus, particularly a kind of medical apparatus and instruments that is used to stop very early pregnancy.

The common method that stops at present both at home and abroad very early pregnancy clinically is traditional uterine aspiration (claiming artificial abortion again) and drug induced abortion, and the shortcoming of uterine aspiration is the person's of undergoing surgery pain when performing the operation.The complication such as the perforation of uterus when easily producing art, adhesion etc., postoperative can produce artificial abortion syndrome, as endometriosis etc.In addition, the shortcoming of drug induced abortion is a high selectivity, and is loaded down with trivial details, and failure is arranged, and bleeding time post-abortion length etc.

The purpose of this utility model is exactly in order to solve a kind of apparatus that stops very early pregnancy of problem design of prior art, to adopt negative pressure-pumping to stop very early pregnancy.

Formation of the present utility model comprises suction pipe and interior brush, suction pipe is made up of brush in an outer tube and, the head end of outer tube is slick round end, sidewall at its near head end has a suction inlet, sidewall at its tail end has brush locking mouth in, and there is brush on the top of interior brush, and interior brush and interior swishing sound rod are connected, interior brush and outer tube wall are close to, and the other end of interior swishing sound rod has brush handle in.

Fig. 1 is a structural representation of the present utility model.

Further specify embodiment of the present utility model below in conjunction with accompanying drawing.

An outer tube 1 of making by the PVC non-toxic material, its pipe range is 15～28 centimetres, internal diameter is 2.8～3.5 millimeters, its head end is made slick round end not hinder myometrium, sidewall at the outer tube near head end has a suction inlet 6, to draw intrauterine tissue substance and blood, one sidewall of the tail end of outer tube has brush locking mouth 3 in, so that the interior brush location of extracting out, in order to avoid shifting forward, interior brush make the tissue substance that sucks in the outer tube pass back into the uterus again, there is brush 2 on the top of interior brush, should interior brush diameter it be 2.9～3.6 millimeters, be close to outer tube Nell wall and do not stay the slit, so that keep negative pressure behind the pull in the outer tube 1, interior brush 2 is connected with interior swishing sound rod 4, the other end at interior swishing sound rod 4 has brush handle 5 in, during use, earlier this apparatus is slowly entered uterine cavity and reach the uterine cavity top, outside pull pull-rod 4 slowly then, location, fixed mouthful of 3 places of brush pin in interior brush 2 is pulled to, at this moment the suction pressure of outer tube can reach 200～400 millimetress of mercury, implantation is in the pregnant capsule of cavity of uterus inner membrance, just can be pumped into along with the negative pressure of suction inlet in the outer tube, repeat so just can exhaust tissue substance several times, reach the purpose that stops very early pregnancy.

The utility model has the advantages that: simple in structure, easy to use, and the success rate height, Patient's no pain, amount of bleeding is few, and can not injure mesometrium, has reinstating menstruation and terminating pregnancy The disposable use of effect apparatus can guarantee not have its reusable cross-infection.
