Problems solved by technology

[0003] In CN206304172U, the utility model patent of "new negative pressure drainage gastric lavage device" is disclosed. This patent has two tubes for liquid inlet and outlet respectively, but its disadvantages are: 1. Gastric lavage liquid passes through two tubes When the tube enters the stomach, because there will be a small amount of gas in the original stomach, the liquid entering the stomach may cause excessive pressure in the stomach, resulting in discomfort or damage to the stomach; 2. When injecting gastric lavage solution into the stomach, Gastric lavage will push the air in the tube into the stomach, which can also cause bloating or damage to the stomach

Abstract

The invention discloses a gastric lavage device capable of discharging air in a gastric lavage tube, which comprises a main tube, an auxiliary tube and a gastric lavage machine, and the gastric lavage machine comprises a gastric lavage liquid outlet for injecting gastric lavage liquid into the stomach and a liquid discharge inlet for discharging the gastric liquid in the stomach; the liquid drainage inlet communicates with an outlet of the main pipe, an inlet of the main pipe is located in the stomach and communicates with the stomach, a switch unit for controlling the main pipe to be opened and closed is arranged in the main pipe, and an openable baffle is arranged at the outlet end of the main pipe; the outlet of the auxiliary tube is positioned between the switch unit and the baffle plate and communicates with the main tube. The auxiliary tube is only used for injecting gastric lavage fluid into the stomach, the main tube is only used for pumping out the gastric lavage fluid, air in the auxiliary tube can be exhausted through the main tube when the gastric lavage fluid is injected through the switch unit, the air in the auxiliary tube is prevented from entering the stomach, and damage or discomfort to the stomach is avoided.

Description

technical field [0001] The invention relates to the field of gastric lavage equipment, in particular to a gastric lavage device capable of discharging air in a gastric lavage tube. 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. Gastric lavage includes emetic gastric lavage and gastric tube gastric lavage. Gastric tube gastric lavage is to insert a gastric tube from the nasal cavity or mouth, through the esophagus to the stomach, first suck out the poison, then inject gastric lavage solution, and discharge the gastric contents , in order to achieve the purp...
