Visible stomach tube guiding device

Abstract

The invention relates to a visible stomach tube guiding device which comprises a hollow pipeline, airbags for fixing a stomach tube and an airbag inflation guide tube. The hollow pipeline is provided with a groove capable of containing most of the stomach tube, a transparent hose which can be bent in any direction is arranged at the front end of the hollow pipeline, and a transparent thin film layer covers a front-end opening of the hose. In the whole pipeline, position of the front end can be adjusted through an internally-arranged fiber bronchoscope for anesthesia to find an entrance of an esophagus to be guided into the esophagus. The airbags which is positioned on the side of the groove in rear of the hose and inclines towards the middle after being inflated can completely surround and fix the stomach tube, and inflation of the airbags is implemented through the guide tube communicated with the airbags and provided with a self-sealing inflation valve. The visible stomach tube guiding device has the advantages of simplicity, convenience and quickness in operation, high success rate in one-time intubation, capability of realizing orthophoric guide by disposing the fiber bronchoscope and reduction of side damage caused by intubation.

Description

technical field [0001] The invention relates to a medical device, which is a visual gastric tube guide for improving the success rate of gastric tube insertion. Background technique [0002] Clinically, it is often very difficult to intubate gastric tubes for patients under general anesthesia during surgery and critically ill patients. Sometimes patients cannot cooperate due to unconsciousness or pain, and gastric tubes are often folded into groups in the oropharyngeal cavity , It is not easy to enter the esophagus, affecting the implementation of treatment and rescue. Under general anesthesia, the swallowing and coughing reflexes disappear, and the patient cannot actively cooperate. The base of the tongue falls back and the endotracheal tube remains in the mouth, pharynx, and trachea to compress the esophageal orifice.

Problems solved by technology

[0002] Clinically, it is often very difficult to intubate gastric tubes for patients under general anesthesia during surgery and critically ill patients. Sometimes patients cannot cooperate due to unconsciousness or pain, and gastric tubes are often folded into groups in the oropharyngeal cavity , not easy to enter the esophagus, affecting the implementation of treatment and rescue

Under general anesthesia, the swallowing and coughing reflexes disappear, and the patient cannot actively cooperate. The base of the tongue falls back and the endotracheal tube remains in the mouth, pharynx, and trachea to compress the esophageal orifice. The pharynx is folded into a ball or goes back into the mouth. At the same time, the pharynx may be damaged by repeated gastric tube insertion, and the anesthesia tube will block the epiglottis, making it more difficult for the gastric tube to pass. Occupied by the dental pads, and it is inconvenient to move, losing important auxiliary channels such as the laryngoscope and finger guidance

Gastric tube intubation under general anesthesia does not cause any pain for the patient, but the success rate is lower than that of routine awake gastric tube intubation

Critically ill patients are often accompanied by unconsciousness or irritability. Any stimulation will increase the patient’s involuntary cooperation. Forcing the conventional method to insert a gastric tube is not only difficult to succeed but also often causes new injuries.
