Gastrointestinal fluid decompression device for gastrointestinal surgery

Abstract

The invention discloses a gastrointestinal fluid decompression device for gastrointestinal surgery, and belongs to the technical field of gastrointestinal medical instruments, the gastrointestinal fluid decompression device comprises a fluid extraction box, a fluid extraction mechanism is fixedly mounted in an inner cavity of the fluid extraction box and used for adjusting fluid extraction pressure, and one side of the fluid extraction box is communicated with one side of a fluid storage mechanism; and the other side of the liquid extraction box is communicated with a liquid extraction stomach tube through a movably connected filtering mechanism. According to the invention, the control on the extraction pressure regulation on the two sides is realized through the change of the air pressure at the bottoms of the first piston seat and the second piston seat, and the one-way valve can control the one-way movement of the extraction pressure of the extraction pump on one side, so that the pressure can be effectively prevented from being influenced when the pressure is stopped; the pressure is reversely transmitted to the corresponding position of the stomach to deviate due to the reverse acting force, the relative stability of gastric juice extraction is improved, meanwhile, the requirement for controlling the extraction pressure is met, the large discomfort of the stomach is avoided, the pressure relief comfort degree is improved, the stress emotion of a patient is avoided, and the use and extraction requirements are met.

Description

technical field [0001] The invention belongs to the technical field of gastrointestinal medical devices, in particular to a gastrointestinal fluid decompression device for gastrointestinal surgery. Background technique [0002] When treating the stomach in gastrointestinal surgery, in order to reduce the impact of the solid-liquid mixture in the gastrointestinal tract on the eyes of the gastrointestinal tract, suction and discharge are generally required to reduce the relative pressure of the gastrointestinal tract. In clinical use, disposable The gastrointestinal decompressor absorbs the gastrointestinal fluid in the gastrointestinal tract through the principle of negative pressure or siphon. [0003] Although the traditional disposable gastrointestinal decompressor has the advantages of easy preparation and large-scale utilization, the negative pressure and siphon environment will easily lead to a drop in abdominal pressure during extraction, which will affect the regulati...

Problems solved by technology

[0003] Although the traditional disposable gastrointestinal decompressor has the advantages of easy preparation and large-scale utilization, the negative pressure and siphon environment will easily lead to a drop in abdominal pressure during extraction, which will affect the regulation of constant gastrointestinal pressure and cause internal bleeding. Secondary injury due to sluggish gastrointestinal pressure cannot meet the safety needs of decompression treatment of gastrointestinal fluid
