Stomach tube capable of judging stomach insertion conveniently

Abstract

The invention discloses a stomach tube capable of judging stomach insertion conveniently. A cap body is fixedly inserted into the bottom end of the stomach tube; a sleeve A and a sleeve B are coaxially arranged on the outer side and the inner side of the top end of the cap body; the sleeve A is matched with an annular notch formed in the position, located at the bottom end, of the outer side wallof the stomach tube, and the sleeve B is matched with the position, located at the bottom end, of the inner side wall of the stomach tube; a pH test solution coating is arranged on the inner wall of the sleeve A; a pull rope is fixedly connected to the bottom of the inner wall of the cap body; the pull rope penetrates through the stomach tube upwards and then is fixed to the bottom of a cover body; and the cap body is made of medical silica gel, and the inner diameter of the stomach tube is twice larger than the thickness of the cap body. Known from the structure of the stomach tube capable ofjudging stomach insertion conveniently, organs contacted with the bottom of the stomach tube are contacted with the pH test solution coating, and whether the stomach tube is inserted into the stomachor not is judged by observing whether the pH value represented by the pH test solution coating corresponds to the pH value of the stomach or not after the cap body is pulled out, so that the insertion position of the stomach tube is conveniently, quickly and accurately judged.

Description

technical field [0001] The invention relates to the technical field of judging whether a gastric tube is inserted into the stomach, and in particular to a gastric tube which is convenient for judging whether it is inserted into the stomach. Background technique [0002] Stomach tube feeding is oral feeding or nasal feeding. For patients who cannot eat orally, the gastric tube is manually inserted into the esophagus through the mouth or nostrils, through the pharynx, through the esophagus to the stomach, and manually pressurized by the syringe push rod and piston. Fetch water and food into the patient's nasogastric tube and stomach to ensure that the patient takes in sufficient nutrients, water and medicines. It is the basic technology that clinical medical care must master. [0003] When intubating, position the patient, clean and lubricate the nasal cavity. Tilt the patient's head back and insert the gastric tube at a 60-degree angle to the nostril, and continue to insert ...

Problems solved by technology

However, the accuracy of this method is not high; sometimes even if the gastric tube has not been inserted into the stomach, there may be no bubbles escaping for a period of time, resulting in misjudgment

[0008] Among the above methods, the actual pH test paper is the most accurate in judging, but it will actually cause greater discomfort and even pain to the patient when extracting gastric juice, so there is an urgent need for an effective, convenient and quick way to judge Whether a gastric tube is inserted into the stomach
