Gastrointestinal decompression equipment for gastrointestinal surgery

Abstract

The invention discloses gastrointestinal decompression equipment for gastrointestinal surgery. The gastrointestinal decompression equipment for gastrointestinal surgery comprises a negative pressure drainage bottle, a negative pressure plug and a pressing board, wherein four spring fixing protrusions are arranged on the side of the top end of the negative pressure drainage bottle in an equidistantmanner, a spring is fixedly connected to the bottom end of each spring fixing protrusion, an interior wall is arranged on one circle of the outside of the negative pressure drainage bottle, and the negative pressure plug is in sliding connection to the interior wall of the negative pressure drainage bottle; and the negative pressure plug is fixedly connected with the four springs at the top endsof the negative pressure plug, a first spiral hole is formed in the center of the negative pressure plug, a pressure column is fixed to the first spiral hole through threads, and the pressing board isfixedly connected to the top end of the pressure column. According to the gastrointestinal decompression equipment for gastrointestinal surgery provided by the invention, through the piston type negative pressure drainage bottle, negative pressure liquid absorbing effects are better and obvious; besides, through design of the pressure column spirally arranged at the top end of the negative pressure plug and the pressing board, operation steps are simplified; and besides, through an efficient negative pressure liquid absorbing function, the intubating time of the nasal cavity of a patient canbe shortened to the maximum extent, and pain of the patient can be alleviated.

Description

technical field [0001] The invention relates to the field of gastrointestinal surgery, in particular to a gastrointestinal 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, the scope of application is very wide, and it is often used in acute gastric dilatation, intestinal obstruction, repair or partial resection of gast...

AI Technical Summary

Problems solved by technology

[0003] The traditional gastrointestinal decompression device only relies on a reboundable balloon to achieve negative pressure operation. The effect of negative pressure suction of this device is not significant, and it cannot avoid liquid backflow. In addition, one or more Multiple drainage bags and frequent bag changes not only increase the workload of medical staff but also bring pain to patients. At the same time, each patient needs at least one drainage bag, which is very wasteful to throw away after use
