Stomach tube capable of preventing gastric distension

Abstract

A stomach tube capable of preventing gastric distension comprises a hollow stomach tube body, two free ends of the stomach tube body are provided with an injection port and an output port respectively, a liquid and gas separator is arranged at one end, close to the injection port, of the stomach tube body, the liquid and gas separator is a container, a cavity is formed inside the container and communicated with the injection port and the output port of the stomach tube body, and the inner diameter of the maximum size position of the cavity is larger than that of the stomach tube body. A ventilation tube is installed on the upper portion of the liquid and gas separator, one end of the ventilation tube is communicated with the cavity of the liquid and gas separator, the other end of the ventilation tube is communicated with the outside, and a liquid-stopping floating body is further installed inside the cavity of the liquid and gas separator and can block a channel of the joint of the cavity and the stomach tube body. The stomach tube capable of preventing gastric distension can effectively prevent air from entering the stomach of a patient, and therefore prevents the patient from having gastric distension.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a gastric tube capable of preventing gastric flatulence. Background technique [0002] In recent years, with the popularization and application of nutrients, more and more patients who cannot eat orally are provided with a liquid diet through gastric tube nasal feeding to ensure adequate intake of nutrients such as protein and calories, thereby promoting the recovery of patients. [0003] Gastric tube is one of the commonly used medical devices in clinic. When in use, a gastric tube is inserted through the patient's nostril by a professional medical staff, passes through the pharynx, and reaches the stomach through the esophagus. Gastric tubes are mostly used to pump gastric juice, and can also be used to inject liquid into the stomach to provide patients with necessary food and nutrition. [0004] Existing common gastric tube is a hollow tube, and the two free ends of the tube a...

AI Technical Summary

Problems solved by technology

The disadvantage of this existing common gastric tube is: when the nurse injects nasal feeding liquid or medicine, the gastric tube needs to be reflexed to reduce the air entering the patient's stomach, so as to avoid the occurrence of abdominal distension of the patient

This not only makes the operation cumbersome, but also if the operation is improper, a large amount of gas may directly enter the patient's stomach, causing abdominal distension and stomach discomfort, aggravating the patient's pain and affecting the patient's recovery; , the patient's body fluid overflows, easily pollutes the ward environment, and easily leads to the spread of infectious diseases
