Abstract

A stomach tube assembly includes a stomach tube and a balloon. The stomach tube is provided with a first cavity channel used for nutrition supply and a second cavity channel used for pressure detection, and the cavity wall of the second cavity channel is provided with an air vent penetrating to the outer wall of the stomach tube. The air bag is provided with an integrally-formed bag body, and the bag body is provided with a cavity and two oppositely-arranged assembling openings. The stomach tube transversely penetrates through the cavity from the assembly opening, the inner wall of the assembly opening is connected with the outer wall of the stomach tube in a sealed mode, and the cavity is communicated with the second cavity channel in a sealed mode through the ventilation opening. The air bag is of an integrally-formed structure and is not provided with abutted seams, and the risk of scratching caused by the abutted seams can be avoided. Moreover, the air bag is directly sleeved on the stomach tube, and the inner wall of the assembly port on the bag body is attached to the axial direction of the outer wall of the stomach tube, so that the air bag is easier to seal, and the sealing reliability can be improved.

Description

technical field [0001] The present application relates to a medical device, in particular to a gastric tube assembly. Background technique [0002] In the medical field, patients usually use various catheters, and gastric tube is one of many catheters. The gastric tube is generally inserted from the patient's nasal cavity, and enters the patient's stomach through the esophagus to provide the patient with nutritional supply or gastrointestinal decompression. [0003] When mechanically ventilating a patient, monitoring the pressure in the esophagus or stomach and calculating parameters from it are of great significance for reducing lung injury during mechanical ventilation. In order to measure the pressure in the esophagus or the stomach, a combination structure of a flexible airway tube and a balloon is usually used to achieve the purpose of measuring the pressure. [0004] A gastric tube with an air bag, the air bag is pasted on the gastric tube, which has the function of ...
