Screw-type gastrointestinal tube

Abstract

The invention discloses a screw-type gastrointestinal tube which comprises a nasointestinal tube, a gastric tube and an inflation tube. The nasointestinal tube, the gastric tube and the inflation tubepenetrate a sleeve, tube caps are mounted on the nasointestinal tube and the gastric tube, through holes are formed in certain ends of the nasointestinal tube and the gastric tube, the certain ends of the nasointestinal tube and the gastric tube are far away from the tube caps, and a traction steel wire is arranged inside the nasointestinal tube. The screw-type gastrointestinal tube has the advantages that the screw-type gastrointestinal tube is provided with the traction steel wire, and effects of traction tubes can be realized by the traction steel wire; the screw-type gastrointestinal tubeis provided with a camera, accordingly, internal conditions of intestines and stomachs can be conveniently observed by medical staffs, and the medical staffs can conveniently carry out catheterization; the screw-type gastrointestinal tube is provided with the inflation tube and an air bag, the air bag can be filled with air by the aid of the inflation tube during catheterization, the intestines and the stomachs can be dilated by the air bag after the air bag is filled with the air, and catheterization can be facilitated; the screw-type gastrointestinal tube is simple in integral structure, suffering of patients due to repeated catheterization can be relieved, and foundations can be laid for one-step successful indwelling; the screw-type gastrointestinal tube can be flexibly and conveniently used and operated and is comfortable and attractive, the through holes are formed in the screw-type gastrointestinal tube, and accordingly blockage can be prevented.

Description

technical field [0001] The invention relates to the technical field of gastrointestinal tubes, in particular to a spiral type gastrointestinal tube. Background technique [0002] With the emergence of animals, the metabolic cycle of nutrition shows a new pattern different from that of plants. From the simplest single-celled animal to the most complex animal - human beings, the process of food digestion has also become complicated. Single-celled animals digest food within the cells, and in multicellular animals with two germ layers, they can realize extracellular digestion and have the function of absorption. The emergence of animals with three germ layers, such as annelids, their digestive organs have been differentiated into foregut, midgut, and hindgut, which can crush and emulsify food for reabsorption. With the emergence of vertebrates, the digestive system of animals has been completely differentiated, and organs such as pharynx, esophagus, stomach, large and small in...
