Nasal-gastric tube

Abstract

The invention provides a nasal-gastric tube. The tube comprises a catheter component and a guide wire component, 6-8 stainless steel balls are arranged at the front end of a catheter of the catheter component, and the outer surface of the catheter is coated with a hydrophilic lubrication coating; the guide wire component comprises a guide wire, a round rubber head is arranged at the head end of the guide wire, and the surface of the guide wire and the inner wall of the catheter are both coated with a hydrophilic lubrication coating or a lyophobic coating. According to the nasal-gastric tube, the surface of the catheter is provided with the hydrophilic lubrication coating, when the tube is used, the hydrophilic lubrication coating can absorb water and expand only by soaking the catheter in sterile water for a while, the catheter feels as smooth as the surface of a loach, and it is facilitated to intubate the tube. In the tube intubation process, the catheter is straightened by the guide wire, and it is convenient for the catheter to enter. It is facilitated for the catheter to pass through the pylorus under the action of gravity of the steel balls at the front end, the catheter can stay in an enteric cavity of a small intestine in an ideal state, the inner wall of the guide wire and the inner wall of the catheter are lubricated, the guide wire can be drawn without hindrance, and after the tube intubation is completed, the guide wire can be drawn out rapidly.

Description

technical field [0001] The invention relates to a medical aid, in particular to a nasogastric tube. Background technique [0002] In the traditional field, for patients undergoing surgery, coma, and stomach inability to eat, etc., the infusion of nutrient solution is usually performed through nasogastric tube feeding in clinical practice. intestine or jejunum. In order to facilitate smooth insertion, the catheter is required to have a certain degree of hardness and elasticity, and it is necessary to coat the surface of the catheter with a lubricant such as liquid paraffin. Clinically, doctors often spend time on catheter insertion, especially for patients who want to insert the duodenum, it is more difficult for the catheter to pass through the pylorus; for patients who need nasal feeding for a long time, frequent replacement of the catheter will bring pain to the patient and increase workload of medical staff.

Problems solved by technology

Clinically, doctors often spend time on catheter insertion, especially for patients who want to insert the duodenum, it is more difficult for the catheter to pass through the pylorus; for patients who need nasal feeding for a long time, frequent replacement of the catheter will bring pain to the patient and increase workload of medical staff

[0003] In order to better solve the above problems, various kinds of nasogastric tubes have been produced and developed, but there are always problems of on
