technical field

The invention relates to the technical field of medical equipment, in particular to a medical pediatric negative pressure gastric lavage device.

Background technique

Gastric lavage refers to pouring a certain composition of liquid into the stomach cavity, mixing the stomach contents and then extracting it, repeated many times, the purpose is to remove the unabsorbed poison in the stomach or clean the stomach cavity. Preparation before surgery and examination. For acute poisoning such as swallowing organic phosphorus, inorganic phosphorus, alkaloids and barbiturates in a short time, gastric lavage is an important rescue measure. Generally, there are two methods of gastric lavage. The first is gastric lavage with vomiting: Vomiting is an instinctive self-defense reaction of the human body to eliminate poisons in the stomach. Because gastric lavage with vomiting is simple and easy to perform, it is an effective on-site rescue for acute poisoning patients who have taken poison for a short time and are conscious. Mutual rescue measures; the second is gastric lavage: inserting a gastric tube from the nasal cavity or oral cavity into the stomach through the esophagus, sucking out the poison first, then injecting the gastric lavage, and expelling the stomach contents to achieve the purpose of eliminating the poison, Patients who take poisons by mouth should have gastric tube lavage as soon as possible, without time limit. For those who take a large amount of poisons within 4 to 6 hours, because of the good detoxification effect and relatively few complications, this type of gastric lavage should be the first choice. At present, when medical personnel perform gastric lavage treatment on pediatric patients, they need to thoroughly clean the stomach through a gastric tube to remove gastric contents or irritants to prevent the absorption of poisons. Cans are thoroughly cleaned for reuse.

At present, most of the gastric lavage tanks and sewage tanks on gastric lavage equipment are integrated with the gastric lavage equipment and cannot be disassembled.
