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.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a blood purification device and a blood purification system constructed with the blood purification device. Background technique [0002] Combined artificial kidney is a blood purification device combined with hemodialysis (HD) and hemoperfusion (HP). It fully utilizes the advantages of hemoperfusion and hemodialysis, and has good biocompatibility, less adverse reactions, and short blood purification time. And other advantages, and can comprehensively remove various toxins in patients with uremia. [0003] The blood purification system composed of the existing combined artificial kidney is composed of four parts: the arterial pipeline of the blood circuit flowing out of the human body, the perfusion device, the dialyzer and the venous pipeline of the blood circuit flowing into the human body. like figure 1 As shown, the blood circuit arterial pipeline is sequentially provided w...

Problems solved by technology

During this process, the operator needs to stop the machine, remove the perfusion device and related pipelines, and perform blood return operation. During the process of removing the perfusion device, it is necessary to disconnect the blood circuit, perform a series of operations such as disassembly and short-circuiting, which is clinically important. This increases the workload of the operator; moreover, if the nurse performs improper operation during the clinical operation, it may cause the patient's blood to be lost, increase the probability of germs invading the patient's blood, increase the pain of the patient, and even cause serious damage to the patient's life. threaten
