Advantages of vacuum blood collection tube and identification method

First, identify the five criteria for qualified vacuum blood collection tubes

1. Aspirating volume experiment: the suction volume, that is, the amount of blood drawn, within ±10% of the error, otherwise it is unqualified. The inability to draw blood is the main problem that currently exists. This not only causes inaccurate inspection results, but also causes blockage and damage of the inspection instrument.
2. Container leakage test: The vacuum blood collection tube containing the sodium fluorescein complex solution was inverted in deionized water for 60 minutes. Under the long-wave ultraviolet light source, the normal visual acuity in the dark room was observed to be non-fluorescent, which was qualified. Container leakage is the main reason for the current inaccurate blood collection of vacuum blood collection tubes.
3. Container strength test: The container was centrifuged for 3000 minutes with a centrifugal acceleration of 3000 g, and the crack was not qualified.  2 meters off the ground, the vacuum blood collection tube does not rupture vertically, so as to prevent the tube from being damaged due to carelessness, resulting in the loss of specimens.
4. the minimum free space experiment: the minimum space to ensure that the blood is fully mixed. The blood volume is 0.5ml-5ml, and the blood volume is +25%; the blood volume is >5ml, and the blood volume is 15%.
5. solvent, solution mass ratio and solution addition accuracy test: the error should be within ± 10% of the specified standard plant. This is a problem that is easily overlooked and common, and is one of the main reasons for the inaccuracy of the test data.

Second, the advantages:

1> The vacuum blood collection tube is made of plastic material, which is light in weight, pressure-resistant, non-fragile, easy to transport, and ensures the safety of medical personnel.
2> The whole blood collection process is a closed system, which is hygienic and safe, ensuring that medical personnel are not exposed to infectious sources.
3> All vacuum tubes are equipped with safety caps to prevent unclean sprays.
4> Anticoagulant tube additive is spray/dry powder/liquid, which is the most effective anticoagulation.
5> The vacuum in the vacuum blood collection tube is accurate and reliable. All additives are automatically added, accurate loading, avoiding the disadvantage of manual addition of poor repeatability, thus ensuring accurate results and good repeatability.
6> The color of the safety cover conforms to international standards, which makes it easy to distinguish between the additives in the tube.
7> The test tube specifications conform to international standards and are fully applicable to various automated analyzers.
8> The vacuum tube is complete in variety, which can meet the blood collection requirements of all laboratories. It can complete the collection of all test samples and reduce the pain of patients.
9> The vacuum tube has a long shelf life of up to 12months.
10> Vacuum tube incineration products are carbon, hydrogen and oxygen, which will not produce toxic gases. The incineration residue is 0.2%, which is an environmentally friendly product.
