Negative-pressure gastric lavage device used in pediatric department

Abstract

The invention relates to the technical field of medical instruments and discloses a negative pressure gastric lavage device used in the pediatric department. The negative pressure gastric lavage device comprises a box body, a liquid storage tank and a pressure pump, wherein the liquid storage tank is arranged inside the box body, the upper end of the liquid storage tank is fixedly connected with two symmetrically arranged first connectors, the two first connectors are both in cylindrical shapes, the insides of the two first connectors are both inserted and connected with second connectors, andthe side walls of the first connectors are provided with two symmetrically formed round holes; balls are movably arranged in the two round holes, the diameters of the two opposite ends of the two round holes are smaller than the diameters of the balls, and annular clamping grooves matched with the balls are formed in the outer circumferential side walls of the second connectors. According to thenegative pressure gastric lavage device used in the pediatric department, a gastric lavage tube, a negative pressure tube and the liquid storage tank are convenient to install and disassemble, the gastric lavage tube and the liquid storage tank are convenient to clean and disinfect, the gastric lavage tube can be protected, and the phenomenon is avoided that gastric lavage tube is exposed to the outside and stained with bacteria and dust and accordingly children are infected when the gastric lavage tube is used.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a pediatric negative pressure gastric lavage device. Background technique [0002] Gastric lavage refers to pouring a certain amount of liquid into the gastric cavity, mixing the gastric contents and then drawing it out, and repeating this many times. The purpose is to remove unabsorbed poisons in the stomach or clean the gastric cavity. gastric lavage is an important rescue measure for acute poisoning such as swallowing organic phosphorus, inorganic phosphorus, alkaloids and barbiturates within a short period of time. During gastric lavage treatment, it is necessary to thoroughly clean the stomach through the gastric lavage tube to remove gastric contents or irritants and prevent the absorption of poisons. [0003] However, in the prior art, the gastric lavage tube and the liquid storage tank on the gastric lavage equipment are generally fixedly connected and cannot be ...
