Three-chamber negative pressure wound irrigation and drainage tube

Abstract

The invention relates to medical consumables for drainage of human wounds, which is a three-chamber negative pressure wound irrigation and drainage tube. It includes an internal drainage tube and an external connection tube; the internal drainage tube is an integral structure, and the internal drainage tube is provided with a main drainage tube, a flushing tube, and a guide wire implantation tube in parallel in the longitudinal direction; the main drainage tube is located in the The geometric center of the drainage tube inserted in the body, the irrigation tube and the guide wire implant are located on the periphery of the main drainage tube; the outer wall of the drainage tube inserted in the body is provided with a lower groove, and there are multiple drainage openings in the lower groove. It is connected with the main drainage tube; the extracorporeal connecting tube includes the independent extracorporeal drainage tube, extracorporeal irrigation tube and extracorporeal guide wire implantation tube; The main drainage tube, irrigation tube and guide wire implant tube at the outer end are in continuous communication. Its main structure is a three-chamber structure, which is used for drainage of deep wounds in the human body, and has the effects of accurate placement, good drainage, flushing, and anti-blockage.

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...

Problems solved by technology

[0002] Nowadays, most wound drainage tubes are single-lumen drainage tubes, and it is difficult to completely drain the pus and secretions from deep wounds

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. Infected, so the wound does not drain well

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.
