Multifunctional hemodialyzer property testing device and use method

Abstract

The invention discloses a multifunctional hemodialyzer property testing device which can be cleaned by self, and a use method. The device at least comprises detection items of property parameters suchas ultrafiltration rates, screening coefficients and pressure drop of hemodialyzers. The device comprises a simulated liquid supply system, a detergent supply system, a blood pump, a pressure sensor,a pressure adjusting valve, a flowmeter, a waste liquid tank and a main controller. The device has the advantages that multiple purposes can be achieved with one machine, the machine is simple and convenient to operate and high in testing speed, testing conditions and data can be displayed and recorded in real time in the testing process, properties under different operation conditions can be sufficiently and completely judged, meanwhile artificial record errors are avoided, testing results are precise and reliable, equipment and pipelines can be cleaned and sterilized after testing is completed, cross pollution of different simulation liquids is avoided, and the testing result stability and accuracy can be improved.

Description

technical field [0001] The invention relates to the field of hemodialyzer performance parameter testing, in detail, it is a multifunctional hemodialysis device capable of detecting multiple properties such as the ultrafiltration rate, screening coefficient and pressure drop of the dialyzer, which is simple to operate, high in accuracy, and repeatable and stable. Device performance testing device and method of use. Background technique [0002] We know that hemodialysis is a method for the treatment of end-stage renal disease. During the treatment process, the blood in the patient's body is drawn out of the body, and the concentration difference between the blood and the dialysate side of the dialysis membrane and the diffusion, convection, filtration and adsorption caused by the pressure difference are used. The role is to complete the removal and exchange of metabolic wastes, toxic substances, water, and electrolytes that need to be removed from the blood, to achieve the ba...

Problems solved by technology

There is no special test equipment for the rest of the performance parameters, and the experimental device needs to be built for each test, and the test process is cumbersome; the different testers build different devices will also affect the accuracy and repeatability of the test results, especially when it comes to the need to obtain Performance parameters such as ultrafiltration rate and pressure drop of pressure value
