Embodiment 1

[0020] Embodiment 1, with reference to attached figure 1 , 2 , 3, 4, 5.

[0021] The present invention includes a handle 2 and a suction tube body 1. The tail of the suction tube body 1 extends into the handle 2 to connect with it. The tube body 1 is divided into three tubular cavities extending along the length direction of the tube body; One chamber is a suction chamber 101, which has a suction inlet 4 and a suction outlet 40; the second chamber is a decompression chamber 102, which has a decompression inlet 5 and a decompression outlet 50; the third chamber is a negative pressure control chamber 103, which has a negative pressure control air outlet 7 and a negative pressure control air inlet 70;

[0022] The suction inlet 4, the decompression inlet 5, and the negative pressure control air outlet 7 are distributed on the front part of the pipe body 1, and the suction outlet 40, the decompression outlet 50 and the negative pressure control air inlet 70 are distributed on th...

Embodiment 2

[0028] Embodiment 2, with reference to attached Image 6 , 7 .

[0029] This embodiment is provided with a visual guide, and the other parts of this embodiment are the same as Embodiment 1. Image 6 , 7 Among them, the same reference numerals represent the same meanings.

[0030] The visual guide is at the head of the suction tube body, and the decompression inlet 5 and negative pressure control air outlet 7 are behind the visual guide.

[0031] The visual guiding device includes a needle camera 12 and a light source 13 .

Abstract

The invention provides a disposable three-cavity one-way bi-pass decompression abortion suction tube which comprises a handle and a suction tube body, wherein the tube body is divided into three tubular cavities; the first cavity is a suction cavity which is provided with a suction inlet and a suction outlet; the second cavity is a decompression cavity which is provided with a decompression inlet and a decompression outlet; the third cavity is a negative-pressure control cavity which is provided with a negative-pressure control air outlet and a negative-pressure control air inlet; the handle is provided with a main interface connected with suction equipment, an inlet connected with the suction outlet of the suction cavity and a flow passage between the main interface and the inlet; the handle is also provided with a one-way outlet and a one-way inlet, and the one-way inlet is communicated with the negative-pressure control air inlet of the negative-pressure control cavity and is provided with a one-way air inlet valve; and the one-way outlet is communicated with the decompression outlet of the decompression cavity and is provided with a one-way air outlet valve. When the disposable three-cavity one-way bi-pass decompression abortion suction tube is used, uterus blood countercurrent during abortion can be prevented so as to prevent endometriosis and barrenness; and uterus wall muscular tension in the abortion is reduced, and bleeding and pains are also reduced and lightened.

Description

technical field [0001] The invention relates to an abortion suction tube. Background technique [0002] The existing abortion suction tube is a single-lumen tube with a single function. When the patient uses the suction tube, when it is inserted and pulled out, it is easy to cause uterine contraction. At this time, the pressure in the uterine cavity increases rapidly. At this time, gas or liquid forms Reverse flushing can easily form endometriosis and lead to infertility. At the same time, it can also stimulate the vagus nerve to form a comprehensive reaction of flow; it is easy to cause negative pressure when it is attracted; The pressure difference becomes larger, which increases the muscle tension of the uterine wall, and the patient is prone to massive bleeding, which not only increases the pain and risk of the patient, but also prolongs the operation time and other disadvantages. Contents of the invention [0003] The technical problem to be solved by the present inv...
