It is easy to judge whether the gastric tube is inserted into the stomach

Abstract

The invention discloses a gastric tube which is convenient for judging whether it is inserted into the stomach. The bottom end of the gastric tube is plugged and fixed with a cap, and the outer and inner sides of the top of the cap are coaxially provided with a sleeve A and a sleeve B. Sleeve A matches the annular notch at the bottom end of the outer wall of the gastric tube, and sleeve B matches the bottom end of the inner wall of the gastric tube; the inner wall of sleeve A is provided with a pH test solution coating, and the inner wall of the cap The bottom is fixedly connected with a stay cord, and the stay cord passes upwards through the stomach tube and is fixed to the bottom of the cover body. The cap body is made of medical silica gel, and the inner diameter of the stomach tube is greater than twice the thickness of the cap body. As can be seen from the above structure, the gastric tube of the present invention is convenient for judging whether it is inserted into the stomach, the organs touched by the bottom of the gastric tube are contacted with the pH test solution coating, and after the cap is extracted, the pH represented by the pH test solution coating is observed. Whether the pH value corresponds to the pH value of the stomach is used to determine whether the gastric tube has been inserted into the stomach, which is convenient for quickly and accurately determining the insertion position of the gastric tube.

Description

technical field [0001] The invention relates to the technical field of judging whether a gastric tube is inserted into the stomach, in particular to a gastric tube which is convenient for judging whether it is inserted into the stomach. Background technique [0002] Intubation of gastric tube is also called oral feeding or nasogastric feeding. For patients who cannot eat orally, the gastric tube is manually inserted into the esophagus through the mouth or nostril, through the pharynx, through the esophagus to the stomach, and manually pressurized by the push rod and piston of the syringe. Fill the patient's nasogastric tube and stomach with water and food to ensure that the patient receives adequate nutrition, water and medicine. It is the basic technology that clinical medical care must master. [0003] Position the patient well when intubating, clean and lubricate the nasal cavity. Tilt the patient's head back and insert the gastric tube at a 60-degree angle to the nostri...

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
