Description

Backflow-preventing gastrointestinal fluid decompression equipment Technical Field The invention relates to the technical field of medical appliances, in particular to backflow-preventing gastrointestinal fluid decompression equipment. Background Gastrointestinal decompression is well known as a method of inserting a gastric tube from the oral or nasal cavity, connecting a disposable gastrointestinal decompression device, and drawing the gastric contents out of the patient's body under the action of negative pressure and siphon principles. The method can suck out gas or liquid in gastrointestinal tract, reduce gastrointestinal pressure, reduce gastrointestinal distention, improve gastrointestinal wall blood circulation, and promote healing and functional recovery of stomach wound. When the existing gastrointestinal fluid decompression equipment is used, the tank body for containing gastrointestinal fluid does not have the function of being fixed at a specified position, so that the safe use of the decompression equipment is affected when the tank body is accidentally toppled, and the existing decompression equipment also does not have the function of preventing the backflow of gastroenteritis, therefore, the gastrointestinal fluid decompression equipment capable of preventing backflow is provided. The above information disclosed in the background section is only for enhancement of understanding of the background of the disclosure and therefore it may include information that does not form the prior art that is already known to a person of ordinary skill in the art.
