Abstract

The invention discloses a dialyzer ultrafiltration performance test liquid, and relates to the blood dialyzer testing field; the dialyzer ultrafiltration performance test liquid is prepared by mixing the following raw materials in parts by mass: 1000 parts of normal saline, 1-9 parts of albumin, and 30-80 parts of carbohydrates; the test liquid viscosity is 2-6 mPa / sec. The dialyzer ultrafiltration performance test liquid has the advantages of simple formula, simple preparation, stable performance, low cost, and high accuracy of test data, and replaces bovine plasma in the prior art.

Description

technical field [0001] The invention relates to the field of testing of hemodialyzers, and in detail relates to a dialyzer ultrafiltration performance test solution capable of replacing bovine plasma, simple in formula, easy to manufacture, stable in performance, low in cost, and high in accuracy of test data. Background technique [0002] The ultrafiltration rate is one of the properties of the hollow fiber dialyzer, which mainly reflects the water removal capacity of the hollow fiber dialyzer, and is also an important performance index for evaluating the hollow fiber dialyzer. In the in vitro performance evaluation, the prior art is to use bovine plasma to test the ultrafiltration rate of the hollow fiber dialyzer. With the continuous expansion of the production scale of dialyzers in our country, the demand for bovine plasma is also increasing. However, there are many problems in the use of bovine plasma. For example, the quality of bovine plasma is greatly affected by th...
