Drainage device self-cleaning system for gastrointestinal nursing

Abstract

The invention discloses a drainage device self-cleaning system for gastrointestinal nursing, and relates to the technical field of medical instruments. The drainage device self-cleaning system comprises a collecting box, wherein the upper side of the left side wall of the collecting box communicates with one end of a stomach tube, and a negative pressure device is fixedly mounted at the top end ofthe collecting box. According to the drainage device self-cleaning system for gastrointestinal nursing, through mutual cooperation of square notches, triangular blades, a fixing block, U-shaped supporting rods and torsional springs, which are arranged, the four triangular blades in each square notch can close the corresponding square notch, and the triangular blades which are arranged can be fixed to the square notches through the arranged torsional springs; only when negative pressure suction is generated in the stomach tube through the negative pressure device, the four triangular blades ineach square notch can be opened, then gas and liquid in the stomach and intestines are sucked into the stomach tube, and when the negative pressure device stops generating the negative pressure suction, the torsional springs can close the triangular blades in the square notches, so that the gas and the liquid pumped into the stomach tube are prevented from flowing back.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a drainage device self-cleaning system for gastrointestinal care. Background technique [0002] Gastrointestinal decompression is to use the principle of negative pressure suction and siphon to insert a gastric tube from the oral cavity or nasal cavity, and suck out the gas and liquid accumulated in the gastrointestinal tract through the gastric tube. It has a wide range of applications and is often used for acute gastric dilatation. , ileus, gastrointestinal perforation repair or partial resection postoperative care, and biliary or pancreatic surgery postoperative care. [0003] During the suction operation of the existing gastrointestinal decompression device, since the gastrointestinal tract is not full of liquid, the gastric tube may be blocked during drainage, and the gastric tube needs to be pulled out for unimpeded cleaning after the gastric tube is blocked. It wi...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a self-cleaning system for a drainage device for gastrointestinal care, which solves the need to pull out the gastric tube for unimpeded cleaning after the gastric tube is blocked, which will reduce the efficiency of gastrointestinal care for patients. To increase the pain of the patient, the notch set on the gastric tube of the existing drainage device is open, and the gas and liquid absorbed in the gastric tube may flow back when using negative pressure suction
