Gastrointestinal integrated tube adopting floating ball bag for measuring pressureTechnical Field
The application relates to the technical field of medical appliances, in particular to a gastrointestinal integrated tube adopting floating ball bags for measuring pressure.
Background
Gastrointestinal dysfunction often occurs in ICU patients, and a number of studies have shown that enteral nutrition (enteral Nutrition, EN) is of significant importance for the maintenance of gastrointestinal function and flora. Nasogastric tube is the clinically preferred EN route. Nasogastric tube is inserted from nostril, through the pharynx through esophagus to reach the pipe of stomach, but because of the characteristics of alimentary canal anatomy and serious patient's gastrointestinal dysfunction, complications such as VAP, gastric retention, alimentary canal hemorrhage, reflux aspiration, diarrhea easily appear when EN is carried out through nasogastric tube, and the result is that the treatment effect is often worse than expected, thereby prolonging the treatment time of the patient and increasing the treatment cost. The nasal intestinal canal has pylorus, so that nutrient substances are directly absorbed by intestinal tracts, more ideal nutrition support can be provided, and the occurrence rate of reflux aspiration and pulmonary infection is obviously reduced.
In the past study, the feeding mode and feeding speed can be adjusted according to the monitoring data of intra-abdominal pressure (intra-abdominal pressure, IAP) and gastric residual quantity (Gastrointestinal Residual Volume, GRV), and the nutrition condition of the patient can be further improved by adopting a dynamic management mode. However, since IAP is not sufficiently accurate due to the influence of objective factors, monitoring of GRV requires an ultrasound professional to perform, and data acquisition is not rapid and direct.
