Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a gastric lavage device used for pesticide poisoning. Background Art

[0002] Organophosphorus pesticides are a type of pesticide that is currently widely used in rural areas. Improper placement or contact during use can lead to poisoning. It can also cause acute poisoning due to accidental ingestion, self-ingestion, or eating food contaminated by pesticides. In order to buy time to save lives, specific integrated rescue equipment is needed to perform gastric lavage on patients to ensure sufficient rescue time.

[0003] Gastric lavage is usually performed with a gastric lavage apparatus. Commonly used air pump gastric lavage apparatuses are usually composed of positive and negative pressure pumps, two air-controlled liquid volume control units, a liquid circuit switching device, an air-controlled integrated valve group, and a sensor control system. Through the liquid circuit switching device and the cyclic switching of the positive and negative pressure pumps, the clean water tank and the sewage tank absorb liquid from the clean water tank and the stomach respectively under the action of negative pressure power, and the clean water tank and the sewage tank discharge liquid into the stomach and the sewage collection barrel respectively under the action of positive pressure power, and the gastric lavage is completed in this cycle.

[0004] Most of the gastric lavage devices in the prior art are connected to the positive and negative pressure pumps through a hose. During the gastric lavage process, the hose is easily pulled due to the movement of the patient or the action of external force. When the pulling force is too large, the hose is easily pulled off, thereby affecting the operation of the gastric lavage device. Summary of the invention

After the gastric lavage is completed, the support plate and the support sleeve descend, so that the sealing cover is separated from the main machine, and the sewage tank and the liquid storage tank can be quickly disassembled, which is convenient for subsequent cleaning of the sewage tank and the liquid storage tank, and is more convenient to use. By setting the protective block, during the gastric lavage process, the protective block can be put into the patient's mouth, and the patient bites on the protective block to support the patient's mouth, avoiding pipe blockage due to forced pressing, and ensuring the stable progress of gastric lavage. The gastric lavage device used after pesticide poisoning is not only convenient for disassembly and assembly of the sewage tank and the liquid storage tank, but also during the gastric lavage process, it can limit the position of the guide tube one and the guide tube two, avoiding the guide tube one and the guide tube two from falling off due to pulling.
