Blood purification device and system

Abstract

The invention provides a blood purification device and a blood purification system constructed by the same, and belongs to the field of blood purification treatment instruments. The blood purification device comprises a perfusion unit, a dialysis unit and a connecting unit. The perfusion unit comprises an adsorption column, a filter cavity of the adsorption column is divided into two or more filter layers through a division board in the axial direction of the adsorption column, and a plurality of communicating holes used for making the filter layers on the two sides of the division board communicated are formed in the division board. The dialysis unit comprises a dialysis column. The connecting unit comprises a first connecting end opening, a second connecting end opening and an opening and closing switch used for controlling communication between the first connecting end opening and the second connecting end opening, the first connecting end opening is used for being fixedly connected with one end opening of the adsorption column in a sealed mode, and the second connecting end opening is used for being fixedly connected with one end opening of the dialysis column in a sealed mode. The blood purification device increases the rate of blood purification treatment on the premise of improving the safety of blood purification treatment.

AI Technical Summary

Benefits of technology

The present technology describes an improved method for treating patient's blood by combining it either through filtrations or direct injection into them. This results in more effective cleanup without requiring complicated procedures like plasma exchange or other steps involved during these processes. Additionally, this new system allows for easy handling when replacing certain components after each procedure while maintaining good performance over its lifetime.

Problems solved by technology

The technical problem addressed in this patents relates to reducing the amount of waste generated from traditional methods involving combination therapy without compromising their effectiveness due to reduced blood circulating speed caused by the use of both hemoconcentric acid bicarbonate solution and plasma albumin preparations. Additionally, current techniques involve prolonging the duration of these treatments while still requiring multiple sessions before they start again.
