Embodiment Construction

[0017] Combine below figure 1 , 2 , 3, and 4 illustrate this embodiment. The present invention relates to the technical field of medical devices, and more specifically relates to a jejunum nutrition tube, which includes a delivery hose 10, a side hole 30, a balloon 40 and a dilation tube 50, and also includes a tube head 20. The connecting pipe 60, the transmission flexible shaft 70 and the steering pipe 80. The pipe head 20 is a hard pipe, and the inside of the pipe wall of the pipe head 20 is provided with a developing layer. The length of the pipe head 20 is 10 mm, which is beneficial to reduce the rotation of the pipe head 20. When the radius, reduce the patient's pain. The tube head 20 is provided with at least two side holes 30, preferably, the side holes 30 are arranged on both sides of the tube head 20, and each side of the tube head 20 is provided with three side holes, which increases the outflow speed of the nutrient solution. When the side hole is blocked, it doe...

Abstract

The invention relates to the technical field of medical instruments, in particular to a jejunum nutrition tube. A developing layer is arranged inside the wall of a tube head, a conveying hose is connected with the tube head through a connecting tube, the head end of an expansion tube is connected with a balloon, the balloon is arranged at the head end of the tube head, a sealing plug is arranged at the tail end of the expansion tube, the expansion tube and a transmission flexible shaft are fixedly connected with the outer walls of two sides of the conveying hose, a hard wire with an arc-shapedstructure is arranged in a steering tube, the head of a shaft core in the transmission flexible shaft is fixedly connected with the tail of the hard wire, internal threads are arranged on the inner walls of the head and the tail of a plastic case of the transmission flexible shaft, and external threads matched with the internal threads are arranged on the shaft core. The position of the tube headin a body can be conveniently displayed, allergic rejection of the human body is avoided, the angle of the tube head can be conveniently adjusted by the aid of the transmission flexible shaft, the hard wire with the arc-shaped structure and the soft connecting tube with a corrugated structure, and the pain of a patient cannot be increased due to rotation of the conveying hose.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more specifically relates to a jejunum nutrition tube for enteral nutrition treatment of patients with weak constitutions and abdominal operations. Background technique [0002] Patients after gastric surgery need to use the jejunal nutrition tube to deliver the nutrient solution directly to the intestinal tract. However, the conventional jejunal nutrition tube has a straight tube head, which is not conducive to passing through the bend of the stomach and intestine. The conventional approach is by turning the extracorporeal portion of the jejunal feeding tube so that the tip portion of the tube is rotated to pass through the bend of the stomach and intestine. However, the outer wall of the jejunal nutrition tube will also irritate the throat, esophagus and intestines and stomach due to rotation, aggravating the pain of the patient. In addition, conventional nutrition tubes are provid...
