Hemodialysis device

Abstract

The invention discloses a hemodialysis device. The device comprises a hemodialysis device body, the hemodialysis device body is provided with a hemodialysis machine, a blood inlet end of the hemodialysis machine is connected with one end of a to-be-purified blood pipeline, a blood outlet end is connected with one end of a purified blood pipeline, a dialysate inlet end is connected with a new dialysate adding tank through a pipeline, and a dialysate outlet end is connected with a waste dialysate collecting tank through a pipeline; the to-be-purified blood pipeline is sequentially provided witha first pressure sensor, a blood pump and a second pressure sensor, an inlet liquid pump is arranged on the pipeline where the new dialysate adding tank is arranged, and electric heat preserving sleeves are arranged on the surface of the blood dialysate machine and the new dialysate tank; the bottom of the dialysate device body is provided with a liftable pressing disc and universal wheels with brakes. The device has the advantages that the temperature can be rapidly adjusted to a proper value by the blood dialysate machine after dialysate is newly added, the whole device can be rapidly and stably fixed after the whole device is stopped, and shaking does not easily take place.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a hemodialysis device. Background technique [0002] Hemodialysis (HD) is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains the blood from the body to the outside of the body through a dialyzer composed of countless hollow fibers, and the blood and the electrolyte solution (dialysate) with a similar concentration to the body are exchanged through diffusion / convection inside and outside the hollow fibers , remove metabolic waste from the body, maintain electrolyte and acid-base balance; remove excess water from the body at the same time, and return the purified blood to the entire process called hemodialysis. [0003] However, the current hemodialysis equipment has the following defects: before the dialysate in the new dialysate tank enters the dialyzer, the temperature of the dialysate is not preheated, resulting in blood and dia...

Problems solved by technology

[0003] However, the current hemodialysis equipment has the following defects: before the dialysate in the new dialysate tank enters the dialyzer, the temperature of the dialysate is not preheated, resulting in blood and dialysate in the entire dialyzer after entering the dialyzer. Due to temperature fluctuations, it takes a long time for the temperature control device of the dialyzer itself to adjust the temperature to an appropriate value, which reduces the dialysis efficiency; at the same time, after the entire hemodialysis device is transferred to the corresponding ward, its fixation is relatively loose, and it only stops with brake casters After the whole device, it will also shake, which will bring safety hazards
