Description

Special breathing circuit adapter for gastrointestinal decompression patient

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a respiratory circuit adapter special for a patient with gastrointestinal decompression.

Background

The gastrointestinal decompression refers to inserting a gastric tube into the stomach of a patient from the oral cavity or the nasal cavity, sucking out gas and/or liquid accumulated in the gastrointestinal tract through the gastric tube by utilizing the principles of negative pressure suction and siphonage, and reducing the pressure and the expansion degree in the gastrointestinal tract, and is commonly used for patients suffering from full stomach in emergency general anesthesia surgery, patients suffering from gastric distention, patients suffering from intestinal obstruction, patients suffering from gastrointestinal perforation repair or patients suffering from partial gastrointestinal resection, patients suffering from biliary tract or pancreatic surgery and the like.

It is very common for patients who clinically perform mask ventilation noninvasive ventilator treatment to carry gastric tubes,

the patient in the severe ward can realize noninvasive ventilation and enteral nutrition treatment, can cause aspiration due to abdominal distension and reflux, endanger life, and can realize intermittent gastrointestinal decompression by adopting enteral nutrition, thereby achieving better effect. General anesthesia patients, because of losing spontaneous breathing, need an endotracheal tube anesthesia machine to control breathing to maintain normal oxygen supply of the body. When the mask ventilates in the induction period, if the mask is not tightly attached to the face, air leakage can be caused, the ventilation effect of the anesthesia machine is affected, and even hypoxia is caused. Clinicians often press the mask harder to reduce the gas leakage, but can make the stomach and intestine decompression tube pressurized deformation, circulate unsmoothly, so that follow-up operation can not normally go on, can lead to the pipeline to shift, deviate from, even unexpected tube drawing in serious cases. The medical safety is extremely influenced, the nursing workload and the nursing risk of easy insertion through the anastomotic stoma when the stomach tube is reset are increased, and the pain and the medical cost of patients are also increased. At present, no respiratory mask adapter special for gastric tube patients is reserved at home and abroad.
