Embodiment 1

[0026] A kind of synthetic blood for testing protective products. The components are: 0.2 parts of sodium carboxymethylcellulose, 0.24 parts of sodium chloride, 0.12 parts of potassium dihydrogen phosphate, 0.43 parts of disodium hydrogen phosphate, and 0.43 parts of disodium hydrogen phosphate. Red 0.1 part, sodium lauryl sulfate 0.01 part, the balance is ultrapure water, the sum of the mass parts of the above-mentioned components is equal to 100 parts.

[0027] The preparation method of embodiment 1 is as follows:

[0028] Weigh 2.0g sodium carboxymethylcellulose into a conical flask filled with 500mL ultrapure water, and dissolve it with magnetic stirring at 60°C for 10 hours. After it is completely dissolved, add 2.4g sodium chloride and 1.2g dihydrogen phosphate Potassium and 4.3g disodium hydrogen phosphate, stir to dissolve completely, add 1.0g amaranth, stir to dissolve, transfer to a clean 1L volumetric flask, add 0.1g sodium dodecyl sulfate, ultrasonically dissolve f...

Abstract

The invention relates to a synthetic blood for detecting protective products. The invention comprises a formula of the synthetic blood and a preparation method of the synthetic blood. The synthetic blood mainly comprises red dye, a surface active agent, a thickening agent, a conductivity and pH regulator and water; the synthetic blood is capable of simulating the parameters of surface tension and the like of the normal blood of the human body, thus being used for testing the synthetic blood penetration resistance performance of the protective products such as a mask and a protection suit.

Description

technical field [0001] The invention relates to an artificially synthesized blood and a preparation method thereof, which belong to a product for testing the performance of protective products. Background technique [0002] Workers in the medical industry are vulnerable to pathogens carried by blood, body fluids, etc. during their work. Medical protective products such as protective clothing and protective masks have the ability to prevent the penetration of liquids, which can reduce the risk of disease infection from blood and body fluids during the work of medical staff. [0003] Liquid penetration resistance is a key indicator for evaluating the protective performance of medical protective products. Domestic and international testing standards for this performance use the detection method of anti-synthetic blood penetration, that is, using artificially prepared liquid (synthetic blood) to simulate Certain properties of blood or body fluids are used to evaluate protective...
