Circulating filtration type gastric lavage machine for gastrointestinal surgery department

Abstract

The invention belongs to the technical field of gastric lavage machines, and particularly relates to a circulating filtering type gastrointestinal surgery gastric lavage machine which comprises a gastric lavage machine shell and a filtering assembly. The filtering assembly comprises a shell mechanism; the shell mechanism comprises an outer shell; a first filtering unit and a second filtering unit are clamped and mounted at the bottom end of the inner wall of the outer shell, and sleeving parts are fixedly connected to the top ends and the bottom ends of the first filtering unit and the second filtering unit. The cover plate mechanism is connected to the top end and the bottom end of the shell mechanism in a clamped mode, a first locking hole and a first sliding groove are used in cooperation, the purpose of guiding installation of a first gastric lavage tube and a second gastric lavage tube is achieved, a second locking hole and a second sliding groove are used in cooperation, and the purpose of guiding installation of a first blow-off tube and a second blow-off tube is achieved; and the assembling efficiency of the filtering assembly and the gastric lavage machine shell is improved.

Description

technical field [0001] The invention belongs to the technical field of gastric lavage machines, in particular to a circulating filter type gastric lavage machine for gastrointestinal surgery. Background technique [0002] Gastric lavage machine is a kind of medical equipment, suitable for medical units, emergency centers, etc. to rescue food poisoning, poisoned patients and gastric lavage before surgery. At present, the structure and function of gastric lavage machines used by most medical units or emergency centers are similar. Most of the circulation systems for the eluate use two-stage filtration or multi-stage filtration. The filtration of the eluate is convenient for classification and detection, reducing the trouble of repeated processing and improving hygienic operability. [0003] At present, the existing circulating filter gastric lavage machine adopts the method of multi-stage filtration, and the components of the multi-stage filtration are often distributed in mul...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing circulating filter type gastric lavage machine is carried out by multi-stage filtration, and the parts of multi-stage filtration are often distributed in multiple positions of the gastric lavage machine, which is often inconvenient when dismantling and cleaning, and it is dirty The filtering effect of the pollutants is not ideal, and multi-stage filtration is superimposed and used together, which is prone to blockage during the filtration process and affects the efficiency of sewage treatment.
