Gastrointestinal fluid depressurizing device for gastrointestinal surgery

Abstract

The invention relates to the technical field of medical equipment, in particular to a gastrointestinal fluid depressurizing device for gastrointestinal surgery. The gastrointestinal fluid depressurizing device comprises a negative pressure attractor, a manual air pump shell is mounted on the upper end face of the negative pressure attractor, a jacket B is mounted on the outer side of the manual air pump shell, a finger rest handle is mounted on the upper end face of the manual air pump shell, a connection rod is mounted on the inner side of the finger rest handle, a handheld handle is mounted on the upper end face of the connection rod, a piston plate is mounted on the lower end face of the connection rod, a rubber pad is mounted on the lower end face of the piston plate, a one-way valve is mounted below the rubber pad, a connection tube is mounted on the lower end face of the one-way valve, and a limiting block A is mounted below the negative pressure attractor. Through cooperation of the limiting block A and a limiting block B, convenience is brought to fixing of the negative pressure attractor; air in the negative pressure attractor is compressed off through a manual air pump, so that negative pressure drainage efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a gastrointestinal fluid decompression device for gastrointestinal surgery. Background technique [0002] With the rapid development of society and economy, gastrointestinal decompression is a commonly used nursing technique in thoracic surgery. Its purpose is to drain gastric fluid and gas in the gastrointestinal tract, reduce abdominal distension and suture tension, and facilitate wound healing. It uses the principle of negative pressure suction to suck out the gas and liquid accumulated in the gastrointestinal tract, so as to reduce the pressure in the gastrointestinal tract, improve the blood circulation of the gastrointestinal wall, facilitate the limitation of inflammation, and drain the accumulation of fluid in the stomach and the accumulation of gas in the gastrointestinal tract. A treatment method, gastrointestinal decompression is to use the principle of negat...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of gastrointestinal fluid decompression device for gastrointestinal surgery, to solve the problem that the negative pressure suction device of the existing gastrointestinal fluid decompression device for gastrointestinal surgery proposed in the above-mentioned background technology does not have a suitable fixing device , so that the negative pressure suction device is easy to fall off, which in turn drives the drainage tube to fall off, causing secondary damage to the patient's body. At the same time, before the negative pressure suction device is used again, it is difficult to remove all the internal air, which greatly reduces the drainage effect, etc. question
