Gastrointestinal fluid pressure-reducing device for gastrointestinal surgery

Abstract

The present invention discloses a gastrointestinal fluid pressure-reducing device for gastrointestinal surgery. The gastrointestinal fluid pressure-reducing device for the gastrointestinal surgery comprises a collecting bucket, the collecting bucket is a transparent bucket body, an upper end of the collecting bucket is screwedly connected with a bucket cover, a drainage tube penetrates an upper surface of the bucket cover, a bottom end of the drainage tube extends into a lower part inside the collecting bucket, one end of the drainage tube is sleevedly connected with a hose, a connection placeof the hose and the drainage tube is provided with a tube clamp, one end of the hose is provided with a drainage head, and the outer side inside the bucket cover is provided with a pressure-reducingtube. The gastrointestinal fluid pressure-reducing device for the gastrointestinal surgery is simple in structure, and convenient and quick in operation, automatically extracts gas and liquid in the gastrointestinal tract, saves time and labor, improves work efficiency, can adjust negative pressure suction, and avoids that the suction is too excessive to damage gastrointestinal mucosa or the suction is too small and not ideal in effects, a head part of the suction head is in a circular arc design to avoid resistance to enter the stomach and prevents water vapor from entering a negative pressure pump, and the gastrointestinal fluid pressure-reducing device prolongs service life and is suitable for popularization use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a gastrointestinal fluid decompression device for 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 resection of ga...

[0003] In the prior art: the patent application publication number of CN 207804675 U discloses a gastrointestinal fluid decompression device for gastrointestinal surgery, including a collection box base, the top of the collection box base is fixedly connected with a collection box that communicates with it. Shell, the top of the telescopic shell of the collection box is fixedly connected with the top cover of the collection box connected with it, one side of the top cover of the collection box is fixedly connected with a pressure plug, the other side of the top of the collection box is provided with a drainage tube, and the bottom of the drainage tube It runs through the top cover of the collection box and extends to its interior to be fixedly connected with the liquid inlet cover. It generates negative pressure by squeezing the telescopic shell of the collection box. It is cumbersome to use and low in efficiency. It is inconvenient to adjust the suction of negative pressure. If it is too large, it will easily damage the gastrointestinal mucosa; if the suction force is too small, the extraction effect will not be ideal
