Gastrointestinal fluid decompression device for gastrointestinal surgery

Abstract

The invention relates to a gastrointestinal fluid decompression device for gastrointestinal surgery. The gastrointestinal fluid decompression device comprises a fluid pumping device, an inflation device, a fluid pumping pipe, a lifting mechanism, an inflation pipe, a double-cavity pipe and an inflation air bag, wherein the fluid pumping device communicates with an inner cavity of the double-cavity pipe through the fluid pumping pipe, and the lifting mechanism drives the fluid pumping device to pump accumulated fluid; and the inflation device communicates with an outer cavity of the double-cavity pipe through the inflation pipe, the inflation air bag is arranged at the pumping end of the double-cavity pipe and communicates with the outer cavity, the lifting mechanism drives the inflation device to supply air to the inflation air bag at the same time, and the inflation air bag bulges to fill abdominal cavity space occupied by extracted hydrops. The lifting mechanism is used for simultaneously driving the fluid pumping device and the inflation device, the inflation air bag is inflated while effusion is pumped, it can be guaranteed that a pipe opening corresponding to the inner cavity is completely inserted into effusion, and the situation that the pipe opening is not completely inserted into the effusion, so that the inner wall of the mucous membrane vibrates, and a patient feels uncomfortable, is avoided.

Description

technical field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a gastrointestinal fluid decompression device for gastrointestinal surgery. Background technique

[0002] In the clinical treatment of gastrointestinal surgery, when the patient has intraperitoneal fluid or increased intraperitoneal pressure, it is necessary to use a gastrointestinal decompressor to drain the gastrointestinal fluid.

[0003] The principle of the commonly used gastrointestinal decompressor at present is to suck out the effusion in the patient's abdominal cavity through negative pressure suction, and the negative pressure work can be realized by siphon structure, piston extraction structure, etc. When extracting liquid under negative pressure, even if the patient is in a sitting or inclined position, the nozzle of the gastric tube may not be completely inserted into the liquid. Once the nozzle is half in the liquid or not in the liquid at all,...
