Multi-head screen hole negative pressure abdominal cavity drainage device

Abstract

The invention discloses a multi-head screen hole negative pressure abdominal cavity drainage device which comprises a drainage tube and an elastic suction bottle, wherein the drainage tube comprises a flexible liquid suction tube and a flexible liquid guide tube, a liquid outlet of the flexible liquid suction tube is communicated with a liquid inlet of the flexible liquid guide tube, and liquid suction holes are distributed on the tube wall of the flexible liquid suction tube; the elastic suction bottle is communicated with the liquid outlet of the flexible liquid guide tube through an air inlet one-way valve, and an exhaust port of an air outlet one-way valve is arranged on the elastic suction bottle. When in use, the flexible liquid suction tube is arranged in the place with accumulated liquid in the abdominal cavity, a tube mouth of the flexible liquid guide tube is lower than the position of the flexible liquid suction tube, liquid enters into the flexible liquid suction tube through the tube mouth of the flexible liquid suction tube and a liquid suction hole and is delivered to the elastic suction bottle through the flexible liquid guide tube, thereby achieving the good drainage effect.

Description

technical field [0001] The invention relates to a multi-head sieve-hole negative pressure peritoneal cavity drainage device for draining exudate, blood, pus, bile and leaked gastrointestinal fluid after abdominal surgery. Background technique [0002] The purpose of surgical drainage is to guide fluids such as exudate, pus, and blood accumulated between human tissues or body cavities to the outside of the body, so as to prevent postoperative infection and affect wound healing. When using the drainage tube clinically, the following points must be paid attention to: ① Keep the drainage tube unobstructed, and observe it at all times. ② When using the drainage tube, pay attention that the position of the outlet of the drainage tube should not be higher than the plane of the intubation port of the patient. When moving the patient, the drainage tube should be clamped first to prevent backflow; Clean the mucous membrane contact area to prevent infection. [0003] In abdominal sur...

AI Technical Summary

Problems solved by technology

[0003] In abdominal surgery, it is often necessary to use a drainage device to remove the fluid remaining in the abdominal cavity after the operation. Most of the drainage tubes of the existing drainage devices are round tubes made of silica gel. When used, they have the following disadvantages: ① Drainage effect Poor, unable to completely remove the residual fluid in the abdominal cavity after surgery, which may easily cause infection of the patient's wound; ②The drainage tube is prone to twisting, bending and compression during use, causing the drainage channel to be blocked, resulting in poor drainage and affecting Drainage effect; ③The range of the drainage tube and the intraperitoneal cavity is limited, which cannot adapt to the situation where multiple drainage needs to be performed at the same time.
