Blood purification device with high safety performance

Abstract

The invention discloses a blood purification device with high safety performance. The device comprises a liquid inlet valve, a dialyzate preparing system, a balancing system, a dialyzer, an ultrafiltration pump and a liquid discharge valve which are installed on a main pipeline in sequence, wherein a cleaning pipeline is connected to the main pipeline as a branch, one end of the cleaning pipeline intersects with the main pipeline at the position between the liquid inlet valve and the dialyzate preparing system, the other end of the cleaning pipeline is connected with the main pipeline through a T-joint control valve, and the control valve is installed on the portion, between the balancing system and the dialyzer, of the main pipeline. By the adoption of the device, the situation that impurities in the portion, behind the dialyzer, of the pipeline enter the portion, in front of the dialyzer, of the pipeline is avoided, and using is safer. The device has the advantages of being ingenious in concept, simple in structure, easy to transform, low in transformation cost and the like.

Description

technical field [0001] The invention belongs to the technical field of blood treatment equipment, and in particular relates to a highly safe blood purification equipment. Background technique [0002] At present, the mainstream methods of blood purification treatment are hemofiltration treatment and hemodialysis treatment. The blood purification equipment used in hemofiltration and hemodialysis treatment is similar, and these blood purification equipment mainly include a liquid inlet valve, a dialysate preparation system, a balance system, a dialyzer, an ultrafiltration pump and a liquid discard valve installed in sequence on the main line. During use, pure water enters the dialysate preparation system through the liquid inlet valve, and the dialysate preparation system inhales liquid B and liquid A in sequence to make dialysate, and the blood drawn from the human body enters the dialyzer and is combined with the dialysate under the action of the ultrafiltration pump. A mat...

AI Technical Summary

Problems solved by technology

However, when performing blood purification treatment, bacteria, viruses and other impurities ultra-filtered from the patient's body are likely to enter the pipeline before the dialyzer during the cleaning process.

These debris entering the front-end pipeline of the dialyzer are likely to enter the human body with the dialysate again during the next blood purification treatment, which not only affects the effect of blood purification treatment, but also may cause harm to the human body, posing a great safety hazard
