Description
Technical Field
The invention belongs to the technical field of medical equipment, and particularly relates to a head-end self-expanding jejunum nutrition catheter, a cleaning assembly and a using method of the cleaning assembly.
Background
Esophageal cancer is a common digestive tract tumor, the typical symptom of esophageal cancer is progressive dysphagia, firstly food which is difficult to swallow dry, then semifluid food, and finally water and saliva can not be swallowed, when a plurality of patients see a doctor, the esophagus is obviously obstructed and can not eat, and an jejunal nutrition path needs to be established for enteral nutrition support. In addition, in order to promote the recovery of patients, jejunal nutrient tubes are often left in patients who undergo esophageal cancer radical surgery during postoperative fasting, and are used for implementing early postoperative enteral nutrition of the patients. At present, no jejunum nutrient canal which is pertinently used for placing in an operation is clinically used, most units select a mushroom head or plum blossom-shaped silica gel-like catheter, the thickness of the catheter is thick, and even if the mushroom head is cut off during placement, the catheter is difficult to place in an intestinal cavity. In addition, after the catheter is placed, the catheter is easy to displace and fall out under the action of external force. In addition, the jejunum nutrient canal used clinically at present is easy to cause pipeline blockage, so a head-end self-expanding jejunum nutrient canal is provided.
The inner wall of the pipeline is changed into a long thread shape, which is similar to a rifling of a gun, so that the smoothness of the pipeline is improved, and the occurrence rate of pipe blockage after operation is reduced. We therefore envisage designing such a tube for the implementation of post-operative enteral nutrition.
