Hemodialysis device for kidney internal medicine

Abstract

The hemodialysis device comprises a dialysis equipment body, a dialysate tank and a waste liquid tank, a dialyzer, a blood pump and a heparin pump are arranged on the outer side of the dialysis equipment body, and the top and the bottom of the dialyzer communicate with an arterial communicating pipe and a venous communicating pipe correspondingly; the lower portion and the upper portion of the dialyzer are communicated with a dialysate inlet pipe and a waste liquid discharge pipe respectively, a groove is formed in the dialysis equipment body, the blood pump comprises a driving motor, a sliding groove is formed in the outer portion of the dialysis equipment body, and a pushing plate is jointly slidably connected into the groove and the sliding groove. And a linkage mechanism is arranged between the pushing plate and the output shaft of the driving motor. When the blood pump is started to enable blood in the body of a patient to enter the dialysate tank through the arterial communicating pipe to be purified, the push plate can slowly push the piston rod upwards to squeeze a heparin agent in the cylinder into the arterial communicating pipe; and the supply amount of the heparin agent can be automatically adjusted according to the flow of blood entering the arterial communicating pipe.
