Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a pediatric negative pressure gastric lavage device with a stable connection. Background Art

[0002] When medical staff perform gastric lavage treatment on pediatric patients, they need to thoroughly clean the stomach through a gastric tube to remove gastric contents or irritants and prevent the absorption of poisons. If harmful substances in the stomach cannot be thoroughly and promptly cleaned, treatment will be delayed and the life of the pediatric patient will be endangered.

[0003] Existing gastric lavage devices mostly use the same gastric tube to deliver liquid medicine and recover waste liquid. When the total amount of liquid medicine exceeds the maximum capacity of the stomach, the gastric tube needs to be removed from the liquid medicine bottle and connected to a waste liquid collector. After the waste liquid is collected, it is then connected back to the liquid medicine bottle for continued gastric lavage. This is inconvenient to operate and may cause an unstable interface and leakage.

[0004] Therefore, in view of the problem that the gastric tube of the existing negative pressure gastric lavage device needs to be repeatedly removed when the total amount of liquid medicine exceeds the maximum capacity of the stomach, a negative pressure gastric lavage device that solves the above problem is needed.
