Problems solved by technology

[0002] During clinical hemodialysis, the patient needs to place a catheter in the neck. When hemodialysis is required, one end of the one-way venous catheter is connected to the neck catheter connector, and the other end is connected to the hemodialysis machine to start hemodialysis. After the dialysis is completed, the one-way venous catheter is separated from the neck catheter, and then the medical staff injects heparin solution into the neck catheter to lock the tube. Effectively avoid blood extravasation, but after the sealing of the tube is completed, the blood will gradually break through the blockage of the heparin solution without external pressure support under the action of blood pressure, causing the blood to enter the tube, then dry up and coagulate, leading to bacterial growth and even blockage In view of the above defects, it is necessary to design an anti-coagulation seal for hemodialysis catheters.

Abstract

The invention discloses a continuous positive pressure device for anti-coagulant catheter sealing fluid of a hemodialysis catheter. The continuous positive pressure device comprises a basal plate, a speed adjusting motor, a driving gear, a supporting platform, a driving rack, a connecting rod, a piston, a placing rod, a main propelling cavity, a connecting cavity, a liquid injecting cavity, a bracket, a first approaching switch, a second approaching switch, an induction column, an accumulator, a first one-way valve, a standby cavity second one-way valve, a liquid supplementing opening, and a protection hood. The continuous positive pressure device disclosed by the invention is ingenious in structure and strong in function; through a reciprocating type movement mechanism, the anti-coagulantcatheter sealing fluid is sequentially filled into a catheter placed at the neck in two sides under positive pressure, so that the phenomenon that the blood is effused and the catheter is blocked iseffectively avoided, the comfort degree of a patient is increased, the economic pressure of the patient is alleviated, and the labor strength of nursing staff is relieved.
