Gastrointestinal fluid decompression device for clinical use in gastrointestinal surgery

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a gastrointestinal fluid decompression device for clinical use in gastrointestinal surgery. The gastrointestinal fluid decompression device comprises a pressure regulating bottle and a dirt collecting bottle, wherein a pressure regulating pipe is inserted into the pressure regulating bottle; the pressure regulating bottle is connected with an air suction pipe, and the air suction pipe communicates with a suction pipe of an aspirator; the bottom end of the dirt collecting bottle is in threaded connection with a collecting bottle, and a sealing plug is arranged in a bottle opening of the dirt collecting bottle; a sliding cylinder is fixed to the sealing plug and located under a liquid guide hose;a light connecting rod is slidably inserted into a sliding pipe through a sliding sealing ring, and a floating ball is arranged at the bottom end of the light connecting rod; a sliding ejector rod isfixed to the upper end face of the sliding sealing ring, and a Y-shaped chuck is fixed to the top end of the sliding ejector rod; a contact switch is arranged on the side wall of the Y-shaped chuck and is in electric signal connection with a control alarm; the phenomenon that when hydrops in the dirt collecting bottle reaches the pipe opening of an exhaust pipe or a drainage pipe, hydrops is prone to flowing back, and then secondary damage to the intestines and the stomach of a patient is caused is avoided.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a gastroenteric fluid decompression device for clinical use in gastrointestinal surgery. Background technique [0002] Gastrointestinal decompression is to use the principle of negative pressure suction and siphon to insert a gastric tube through the mouth or nasal cavity, and suck out the gas and liquid accumulated in the gastrointestinal tract through the gastric tube, which can reduce the pressure in the gastrointestinal tract for patients with gastrointestinal obstruction. For patients with gastrointestinal perforation, the pressure and expansion can prevent the gastrointestinal contents from leaking into the abdominal cavity through the breach, and is conducive to the healing of the anastomosis after gastrointestinal anastomosis. Therefore, it has a wide range of applications and is often used for acute gastric dilatation, intestinal obstruction, repair or partial re...

Problems solved by technology

[0004] Although the above content can solve the problem of avoiding too much damage to the gastrointestinal mucosa or too little suction, the effect is not ideal; at the same time, the collection bucket can be disassembled and installed on the cylinder cover, so as to clean up the effusion in the collection bucket; Most of the collection barrels of the pressure device are set in a transparent state, requiring medical staff or nursing staff to frequently observe the liquid level in the collection barrel, and then clean the collection barrel. This method is not conducive to the medical staff to accurately grasp the liquid in the collection barrel. When the liquid level of the effusion is higher than that of the drainage tube, it is easy to cause the effusion to reflux, which in turn leads to secondary damage to the patient's gastrointestinal tract
