Stomach tube convenient to mount and dismount and used for digestive system department

Abstract

The invention relates to the technical field of medical instruments, and discloses a stomach tube convenient to mount and dismount and used for digestive system department. The stomach tube comprises a buccal tube, wherein the top of the buccal tube is in threaded connection with a lower fixing ring, the bottom of the lower fixing ring is fixedly provided with an outer stomach tube, the top of the lower fixing ring is detachably provided with an upper fixing ring, a supporting tube is fixedly arranged at the bottom of the upper fixing ring, the outer stomach tube is connected with the supporting tube in a matched and sleeved mode, an inner stomach tube is arranged in the supporting tube in a sleeved mode, and the bottom end of the outer stomach tube is overturned inwards, stretches into the supporting tube and is fixedly connected with the outer wall of the bottom end of the inner stomach tube. The outer stomach tube turns over from inside to outside along with pushing of the supporting tube, and the outer stomach tube is in contact with the esophagus in a laying-like manner, so friction is avoided, damage to the esophagus is avoided, and discomfort of a patient is avoided; when the stomach tube is pulled out subsequently, the inner stomach tube is pulled out, the outer stomach tube is driven by the inner stomach tube to turn over from outside to inside to enter the supporting tube, and the supporting tube is lifted out, so friction with the esophagus is avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a stomach tube for gastroenterology which is easy to install and disassemble. Background technique [0002] Indwelling gastric tubes are widely used clinically, and are often used for nutritional support and gastrointestinal decompression. Nasogastric feeding through gastric tube provides nutrition, heat and intragastric administration for comatose patients or patients who cannot import and eat. It is one of the main methods to promote the recovery of patients. Gastrointestinal complications; effective gastrointestinal decompression can reduce gastrointestinal pressure, reduce abdominal distension, promote incision healing, improve blood circulation in the gastrointestinal wall, and promote recovery of digestive function. It can effectively reduce complications during and after anesthesia, and is extremely important for postoperative recovery. There are different specif...
