Gastrointestinal fluid decompression device for clinical use in gastrointestinal surgery

Abstract

The invention belongs to the technical field of medical devices, in particular to a gastroenteric fluid decompression device for clinical use in gastrointestinal surgery; it includes a pressure regulating bottle and a dirt collection bottle; a pressure regulating tube is inserted into the pressure regulating bottle; suction pipe, and the suction pipe is connected with the suction pipe of the suction device; the bottom end of the dirt collection bottle is threadedly connected with a collection bottle, and a sealing plug is arranged in the mouth of the dirt collection bottle; a sliding cylinder is fixed on the sealing plug, and The sliding cylinder is located directly below the catheter hose; a lightweight connecting rod is slidably inserted into the sliding tube through a sliding sealing ring, and the bottom end of the lightweight connecting rod is provided with a floating ball; the upper end of the sliding sealing ring is fixed with a sliding ejector rod, And the top of the sliding ejector rod is fixed with a Y-shaped chuck; the side wall of the Y-shaped chuck is provided with a contact switch, and the contact switch is connected to the electrical signal of the control alarm; to prevent the liquid in the collection bottle from reaching the exhaust pipe Or at the mouth of the drainage tube, it is easy to cause the phenomenon of fluid reflux, which in turn leads to secondary damage to the patient's gastrointestinal tract.

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
