Anti-aspiration stomach tube

Abstract

The invention discloses an anti-aspiration stomach tube. The anti-aspiration stomach tube comprises a tube body, one end of the tube body is an insertion end, and the other end of the tube body is anexternal end. A PH detector and an air blowing device are arranged at the external end of the tube body, a first air bag and a second air bag are sequentially arranged on the outer wall of the tube body, and the first air bag is close to the insertion end. The first air bag is connected with a first air pipe, and the first air pipe extends towards the external end and is connected with the air blowing device. The second air bag is connected with a second air pipe, and the second air pipe extends towards the external end and is connected with the air blowing device. The pipe body is further provided with a first PH value sensor and a second PH value sensor, the first PH value sensor is in communication connection with a PH detector, the second PH value sensor is close to the second air bag,and the second PH value sensor is in communication connection with the PH detector. The structure is simple and reasonable, and aspiration can be effectively prevented; and meanwhile, esophageal reflux can be effectively predicted, and the use effect of the whole structure is improved.

Description

technical field [0001] The invention relates to the technical field of kitchen utensils, in particular to an anti-aspiration gastric tube. Background technique [0002] When patients encounter diseases of the central nervous system, such as stroke, coma, and other severe ICU illnesses, patients often need to indwell a gastric tube to provide nasogastric feeding, nutrition, and maintenance of normal intestinal mucosal barrier function. However, the swallowing radiation function of such patients is often poor, and the long-term indwelling gastric tube is easy to damage the esophageal annular sphincter and other reasons, which will lead to food reflux, coughing, aspiration, aspiration pneumonia and even suffocation. Among them, aspiration and the aspiration pneumonia caused by it are the most serious complications, and the mortality rate is as high as 40-60%. This is also an important reason for gastric tube feeding to easily cause aspiration and aspiration pneumonia. Therefor...

AI Technical Summary

Problems solved by technology

[0003] In order to prevent aspiration, the traditional gastric tube uses an inflatable balloon to block esophageal reflux. Although it has a certain degree of anti-aspiration function, it cannot accurately prevent the occurrence of esophageal reflux due to its lack of ability to predict the occurrence of esophageal reflux. It requires long-term uninterrupted application of preventive devices, that is, long-term inflation of the air bag, so that the air bag compresses the esophageal mucosa, resulting in erosion and necrosis, and even serious complications such as perforation, or intermittent use of the air bag, but at intervals During this period, the stomach tube actually has no preventive function, so it is more dangerous to use the stomach tube for nasal feeding for a long time, so the traditional stomach tube is only used for a short time, or patients with clear consciousness who have medical care for 24 hours
