Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically, to a portable vomiting device. Background Art

[0002] There are two common clinical symptoms of digestive system diseases: First, nausea and vomiting. Nausea is an uncomfortable feeling of urgency and nausea, and vomiting is the spitting out of gastric contents or part of intestinal contents through the esophagus. Second, upper gastrointestinal bleeding. Upper gastrointestinal bleeding refers to bleeding caused by lesions in the digestive tract above the ligament of Treitz, including the esophagus, stomach, duodenum, and bile duct. When there is a large amount of bleeding in the upper gastrointestinal tract, blood in the stomach or refluxed into the stomach is vomited out through the mouth, which is called hematemesis. If the amount of bleeding is large and the time it stays in the stomach is short, fresh red or dark red blood may be vomited out. Vomiting blood generally refers to bleeding caused by the upper gastrointestinal tract.

[0003] Gastroenterology deals with diseases of the esophagus, stomach, intestines, liver, gallbladder, and pancreas. Diagnosis is typically made through gastroscopy, colonoscopy, and ultrasound. However, vomiting may occur after gastroscopy and colonoscopy. Gastroscopy and colonoscopy are invasive procedures that mechanically irritate the digestive tract. Some patients may experience nausea and vomiting during and after the procedure.

[0004] Patients in hospitals may vomit when feeling uncomfortable after treatment or examination of digestive system diseases. Patients vomit irregularly, and it is generally difficult to control the sudden situation when vomiting occurs, and it is difficult to use trash cans in time. At the same time, vomitus comes out of the stomach or digestive tract, carrying gastric acid and accompanied by a strong pungent odor. When patients vomit in public places, there will be problems such as vomitus odor and vomitus being difficult to clean. Not only may the patients themselves be contaminated with vomitus, which is inconvenient to clean, but it will also cause great trouble to other patients and medical staff in the hospital. In addition, at some special times, due to the patient's own physical reasons, relevant examinations cannot be carried out, and vomitus needs to be tested to facilitate diagnosis. When vomiting occurs suddenly and the vomitus sample cannot be collected well, the patient or medical staff will feel uncomfortable when collecting the vomitus.
