Stomach tube intubation depth identification device and manufacturing method thereof

Abstract

The invention discloses a stomach tube intubation depth identification device and a manufacturing method thereof. The stomach tube intubation depth identification device disclosed by the invention comprises a stomach tube, and a guide wire capable of being inserted into the stomach tube, wherein the guide wire is provided pH cotton yarn, and the pH cotton yarn is obtained by adsorbing the juice of red cabbage and drying; and the stomach tube is provided with a stomach tube hole, and the stomach tube hole is adjacent to the tail end of the stomach tube. The manufacturing method of the stomach tube intubation depth identification device disclosed by the invention comprises the following steps of: respectively taking one stomach tube with the stomach tube hole, and one guide wire capable of being inserted into the stomach tube; taking the cotton yarn; and coiling the pH cotton yarn on the guide wire, wherein the pH cotton yarn is obtained by adsorbing the juice of red cabbage and drying. The stomach tube intubation depth identification device is nontoxic and harmless, and low in cost; and the cotton yarn contains the acid-base mixed indicator, but the acid-base mixed indicator is purely extracted from the vegetable, namely the red cabbage, so that the acid-base mixed indicator is nontoxic and harmless to a human body, steady in chemical properties, free from time influence and low in cost.

Description

Technical field: [0001] The invention belongs to the technical field of medical devices, and relates to a gastric tube intubation depth identification device and a manufacturing method thereof. Background technique: [0002] Gastric intubation is a commonly used clinical technique. It is often used to drain gastrointestinal contents through a gastrointestinal decompression tube, or to infuse liquid food through a gastric tube for patients who cannot eat orally to ensure that the patient has enough intake. Nutrition, hydration and medication. Therefore, after the gastric tube is inserted, it is often necessary to judge and confirm that the gastric tube is in the stomach and not in the bronchus, so as to avoid suffocation caused by mistakenly injecting the injected material into the airway. Therefore, it is very important to judge the position of the gastric tube after insertion. There are usually three methods: extracting gastric juice, listening to the sound of gas through ...

Problems solved by technology

However, in some patients with respiratory tract infection, phlegm blocks the trachea. Even if the gastric tube is inserted into the trachea, there may not be obvious bubbles escaping. At this time, it is easy to cause the false impression that the gastric tube is in the stomach.

[0006] It can be seen that none of the above three methods can conveniently and accurately judge whether the gastric tube is in the stomach, especially for elderly patients with respiratory tract infection, whose airway is not sensitive to foreign bodies, and sometimes the cough reflex is not sensitive or the sputum sound is obvious or Phlegm blocks the trachea or there is little gastric juice, etc. In these cases, conventional methods cannot quickly, conveniently and accurately determine whether the inserted gastric tube is in the stomach or in the bronchi
