Three-cavity negative-pressure wound irrigation and drainage tube

Abstract

The invention relates to medical human body wound drainage consumables and provides a three-cavity negative-pressure wound irrigation and drainage tube. The negative-pressure wound irrigation and drainage tube comprises an in-vivo drainage tube and an in-vitro connection tube, wherein the in-vivo drainage tube adopts an integral structure and is provided with a main drainage tube, an irrigation tube and a guide wire implanting tube which are parallelly arranged lengthways; the main drainage tube is arranged in the geometric center of the in-vivo drainage tube, and the irrigation tube and the guide wire implanting tube are located at the periphery of the main drainage tube; a lower groove is formed in the outer wall of the in-vivo drainage tube, and a plurality of drainage openings are formed in the lower groove and communicated with the main drainage tube; the in-vitro connection tube comprises an in-vitro drainage tube, an in-vitro irrigation tube and an in-vitro guide wire implanting tube which are mutually independent; the in-vitro drainage tube, the in-vitro irrigation tube and the in-vitro guide wire implanting tube are respectively communicated with the main drainage tube, the irrigation tube and the guide wire implanting tube which are arranged at the outer end of the in-vivo drainage tube. The three-cavity negative-pressure wound irrigation and drainage tube mainly adopts a three-cavity structure, is used for drainage of wounds deep in a human body and has the effects of being accurate in implanting, favorable in drainage and irrigation, resistant to blockage, and the like.

Description

technical field

[0001] The invention relates to a medical consumable material for drainage of human wounds, in particular to a three-chamber negative pressure wound irrigation and drainage tube. Background technique

[0002] Nowadays, most wound drainage tubes are single-lumen drainage tubes, and it is difficult to completely drain the deep wound pus and secretions. Because the drainage tube is soft and difficult to place deep into the wound, negative pressure suction can easily cause lumen occlusion due to the lack of support in the lumen, and single-lumen tubes cannot be used to rinse the wound. Infection, so the wound drainage effect is not good. At present, the irrigation of deep wounds is composed of two independent pipes, and the drainage tube is circular; it is not convenient to manage the drainage tube, and it is easy to be blocked by the surrounding soft tissue during drainage because there is no support around the drainage tube mouth. Continuous negative pressure...
