Nasogastric tube assembly with magnetic positioning function

Abstract

The invention discloses a nasogastric tube assembly with a magnetic positioning function. The nasogastric tube assembly with the magnetic positioning function comprises a gastric tube, an insertion piece and a gastric tube positioning sensor, wherein the gastric tube is a long flexible tube, film pressing assemblies are arranged on the end portion of the insertion end of the gastric tube and the side tube wall of the front end of the gastric tube, the insertion piece is inserted from the tail of the gastric tube and penetrates to the front end of the inside of the gastric tube, the front end of the insertion piece is composed of a strong magnet, the insertion tip of the insertion piece is wrapped by PH test paper, the gastric tube positioning sensor is arranged at the front chest and abdomen part of the outside of a human body, the gastric tube positioning sensor is a transparent sealed compass-shaped plastic container with built-in magnetic fluid, an anti-sliding sleeve handle is tightly arranged on the tail of the insertion piece, a gastric tube connector is fixed on the anti-sliding sleeve handle, the anti-sliding sleeve handle is hollow, an injection cavity is formed in the tail of the anti-sliding sleeve handle, and the injection cavity communicates with a gastric tube cavity. According to the nasogastric tube assembly with the magnetic positioning function, the position of the tail end of the gastric tube when the gastric tube is inserted can be conveniently judged, the PH value of gastric juice can be conveniently detected, and moreover, the anti-backflow effect in the gastric tube cavity can be achieved.

Description

technical field [0001] The invention relates to the technical field of indwelling gastric tubes, in particular to a magnetic positioning nasogastric tube assembly. Background technique [0002] Stomach tubes are used in special cases to help deliver necessary fluids and food to patients who cannot swallow. Clinically, many patients who are unconscious, unable to eat on their own, and need long-term catheterization and regular replacement of gastric tubes, find it difficult to judge the position of the catheterization, and reflux of gastric contents into the gastric lumen due to coughing, etc. Adverse events of gastric tube entering the trachea have been reported. Now most hospitals have implemented the method of routinely extracting gastric juice after tube placement, listening to the sound of air passing through water, and the method of bubble escape to determine the position of the gastric tube, and also need to monitor the pH value of the gastric juice. If the pH value o...

Clinically, many patients who are unconscious, unable to eat on their own, and need long-term catheterization and regular replacement of gastric tubes, find it difficult to judge the position of the catheterization, and reflux of gastric contents into the gastric lumen due to coughing, etc. Adverse events of gastric tube entering the trachea have been reported. Now most hospitals have implemented the method of routinely extracting gastric juice after tube placement, listening to the sound of air passing through water, and the method of bubble escape to determine the position of the gastric tube, and also need to monitor the pH value of the gastric juice. If the pH value of the gastric juice cannot be detected, X-ray filming is required for confirmation. However, in actual clinical operations, patients often have too little gastric juice and it is difficult to withdraw it for testing. Filming is required for confirmation, which also invisibly increases the patient's radiation damage.
