Description

A nursing device for upper gastrointestinal bleeding in department of gastroenterology

technical field

The invention relates to the technical field of medical devices, in particular to a nursing device for upper gastrointestinal bleeding in the Department of Gastroenterology.

Background technique

Medical technology refers to the diagnosis and treatment measures taken by medical institutions and their medical staff to diagnose and treat diseases, make judgments on diseases and eliminate treatments, alleviate diseases, relieve pain, improve functions, prolong life, and help patients recover. . Medical technology is divided into three categories: the first category of medical technology refers to the technology with definite safety and effectiveness, and medical institutions can ensure its safety and effectiveness in clinical application through routine management; the second category of medical technology refers to the technology , Effectiveness, health administrative departments should be controlled and managed medical technology.

Among them, the gastric tube is a medical device often used clinically in the upper gastrointestinal tract in the Department of Gastroenterology of the hospital. After inserting the gastric tube into the stomach, there are currently three methods to check whether the gastric tube is inserted into the stomach. The first method: after inserting the gastric tube, Use a sterile syringe connected to the end of the catheter to draw back to see if the gastric juice can be drawn out. In this method, the premise that the gastric juice can be drawn out must be that there is something in the patient's stomach. Some of the gastric tubes are inserted in patients after emergency operations. After several hours of gastric emptying, the patient’s stomach is already empty, and generally nothing can be extracted. Moreover, this method is affected by the position of the receptor and the depth of gastric tube insertion. Sometimes, the head of the gastric tube It is not possible to have intimate contact with a small amount of gastric juice in the stomach, so we can only try again by changing the body position or adjusting the length of the gastric tube insertion. Such tossing back and forth is sometimes limited by the disease, and it also increases the pain of the patient virtually. ; The second method: Put the end of the catheter into a bowl filled with cold boiled water or saline to see if there are any bubbles overflowing. According to clinical experience, if the gastric tube is inserted to a predetermined length, even if it is not in the stomach, it may not be in the stomach. In the trachea, it may twist in the throat cavity, or any place where the esophagus enters the gastric passage. At this time, even if there is no bubble overflow, it is not sure that the gastric tube must be in the stomach; the third method: listen to the sound of air passing through water , use a sterile syringe to inject 10-20ml of air into the gastric tube, place the stethoscope on the upper abdomen of the patient, and listen for the sound of air passing through the water. This method is relatively reliable and is the most used method. In general, You can also use your hands instead of a stethoscope. As mentioned above, put your left hand on the patient's stomach, use your right hand to draw air with a 50ml syringe, and inject air into the gastric tube in a pulsed way, and use your hands to feel what happens when the air is injected into the stomach. Ups and downs, but this operation will also cause more air in the stomach in a short period of time, which cannot be discharged in time, which will cause flatulence and bring unnecessary pain to the patient.

In view of this, the inventor proposes a nursing device for upper gastrointestinal bleeding in the Department of Gastroenterology, which has the advantage of judging whether the gastric tube has reached the stomach only through the color change, and does not need other verification steps to determine, solving the above problems The problem.
