Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical appliances, and particularly relates to a stomach tube fixing device for gastric lavage. BACKGROUND

[0002] Gastric lavage refers to repeatedly pouring liquid into the stomach cavity and then sucking out the liquid mixed with the stomach contents to remove the unabsorbed poisons in the stomach or clean the stomach cavity, for example, acute poisoning caused by swallowing organophosphorus, inorganic phosphorus, alkaloids and barbiturates within a short time. In clinical practice, gastric lavage is performed by inserting a stomach tube into the stomach through the mouth and esophagus of a patient. At present, the stomach tube for gastric lavage needs to be fixed when it is inserted into the patient's mouth. The existing fixing method is to use medical adhesive tape. However, this fixing method not only causes pain or injury to the patient's face when the medical adhesive tape is removed, but also affects the fixing stability of the medical adhesive tape due to the soaking of the medical adhesive tape by secretions or liquids during gastric lavage, which may cause the medical adhesive tape to come off. In addition, the stomach tube is directly placed in the patient's mouth without being isolated from the teeth, which may cause the stomach tube to be closed or damaged by the teeth, affecting the smooth performance of gastric lavage. SUMMARY

[0003] In view of the above problems, the utility model aims to provide a stomach tube fixing device for gastric lavage to solve the problems mentioned in the background.
