Dialysis pipeline for hemofiltration combined with hemoperfusion

Abstract

A dialysis pipeline for hemofiltration combined with hemoperfusion comprises an injection pipe, one side of the outer surface of one end of the injection pipe is connected with a guide-in pipe, one end face of the injection pipe is connected with a first connecting pipe, one end of the first connecting pipe is connected with a constant-speed mechanism, the constant-speed mechanism comprises an output pipe, one end of the output pipe is connected to one end face of the first connecting pipe, and the other end of the output pipe is connected with the other end face of the first connecting pipe. After blood passes through an output pipe, the blood flows into a first rubber sleeve on a vibration mechanism through a connecting shell and then flows into a vibration pipe through the first rubber sleeve, the vibration pipe enables a rotating shaft to drive a cam to rotate through power of a motor, and the cam can abut against the outer surface of the vibration pipe in the rotating process, so that the blood is output. And the vibration tube can move towards one side by utilizing the toughness of the first rubber sleeve and the second rubber sleeve at the two ends of the vibration tube, and in the moving process, formed blood blocks are decomposed by blood in the vibration tube through the anti-fixing rod, and the blood is prevented from being solidified in the flowing process.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a dialysis pipeline for hemofiltration combined with blood perfusion. Background technique [0002] The commonly used blood purification modes in my country's medical industry include hemodialysis, hemoperfusion and hemofiltration. Generally, it is a single treatment mode, and the blood pipeline used is a special pipeline for hemodialysis. Follow the special pipeline for hemodialysis. The hemodialysis treatment time is 4 hours, and the hemoperfusion treatment time is 2 hours. Therefore, after 2 hours of hemodialysis + hemoperfusion treatment, the blood in the perfusion device must be returned to the human body with normal saline or air, and then separated and connected to the perfusion device. Remove the perfusion tube, connect the tube back to the dialyzer, and continue hemodialysis for two hours. [0003] In the prior art, after the blood is filtered, the filtered bloo...

Problems solved by technology

[0003] In the prior art, after the blood is filtered, the filtered blood will flow into the syringe, and then the filtered blood will flow into the patient's body through the syringe. In the process of flowing in, the blood will sometimes coagulate in the pipeline, causing blood Blockage, the impact of blood loss on patients, and waste of pipes, need to be replaced, and sometimes the pipes are too long, not only occupying space, but also easy to entangle, and hinder the work of medical staff
