According to the pharmaceutical industry standard YY 0314-1999 idt ISO 6170:1995 of the People's Republic of China, if one of the following five indicators is missing, it is considered an unqualified product.
1. Suction volume experiment: The suction volume, i.e. the amount of blood drawn, has an error of ± 10%, otherwise it is considered unqualified. The inaccurate amount of blood drawn is currently the main problem. This not only results in inaccurate inspection results, but also causes blockage and damage to the inspection instruments.
2. Container leakage experiment: Invert a vacuum blood collection tube containing a sodium fluorescein composite solution in deionized water for 60 minutes. Under a long wavelength ultraviolet light source, observe normal vision in a dark room without fluorescence, and it is considered qualified. Container leakage is the main reason for the inaccurate amount of blood drawn from vacuum blood collection vessels at present.
3. Container strength test: The container is subjected to a centrifugal acceleration of 3000g for 10 minutes using a centrifuge, and it is considered qualified if it does not rupture. The strict requirement in foreign countries is that the vacuum collection tube should be placed 2 meters above the ground and not rupture when placed vertically, which can prevent accidental damage to the test tube and loss of the specimen.
