Description

A special breathing circuit adapter for patients with gastrointestinal decompression

technical field

The utility model relates to the technical field of medical devices, in particular to a special breathing circuit adapter for patients with gastrointestinal decompression.

Background technique

Gastrointestinal decompression refers to inserting a gastric tube into the patient's stomach from the oral cavity or nasal cavity, and using the principle of negative pressure suction and siphon to suck out the gas and/or liquid accumulated in the gastrointestinal tract through the gastric tube, which can reduce the pressure in the gastrointestinal tract. It is often used in emergency general anesthesia patients with full stomach, gastric dilation, intestinal obstruction, gastrointestinal perforation repair or partial gastroenterectomy, and patients after biliary or pancreatic surgery.

Clinically, it is very common for patients undergoing face mask ventilation and non-invasive ventilator to carry gastric tubes.

Abdominal distension and reflux can cause aspiration due to non-invasive ventilation and enteral nutrition therapy for patients in the intensive care unit, which is life-threatening. Enteral nutrition and intermittent gastrointestinal decompression at the same time have achieved good results. Patients under general anesthesia need an endotracheal intubation anesthesia machine to control breathing to maintain the body's normal oxygen supply due to loss of spontaneous breathing. When performing mask ventilation during the induction period, if the mask is not tightly fitted to the face, it will cause air leakage, affect the ventilation effect of the anesthesia machine, and even lead to hypoxia. Clinicians usually press the mask harder to reduce air leakage, but this will cause the gastrointestinal decompression tube to be compressed and deformed, resulting in poor circulation, so that follow-up operations cannot be performed normally, and in severe cases, it may lead to displacement, prolapse, or even accidents Extubation. Extremely affecting medical safety, it not only increases the nursing workload and the nursing risk of easy insertion of the anastomosis when resetting the gastric tube, but also increases the patient's pain and medical expenses. At present, there is no special respiratory mask adapter for patients with stranded gastric tubes at home and abroad.
