AI Technical Summary
When using coagulation agents in existing blood blood collection vessels, fibrin precipitation and blockage are prone to occur, resulting in obstruction of blood collection and centrifugation operations, affecting the accuracy of detection.
A blood collection tube with airbag deformation strips was designed. The deformation strips were deployed through the air in the airbag bag, and the needle tube was pushed through the fibrin area smoothly to achieve sample extraction and centrifugation.
It effectively solves the problem of fibrin precipitation and blockage, ensures the accuracy of the detection sample and the cleanliness of the environment, and avoids interference from external equipment and virus contamination.

Abstract
Description
Technical Field
[0001] The utility model belongs to the field of blood centrifugation, and in particular relates to a multifunctional blood centrifuge and a blood collection tube thereof. Background Art
[0002] Fibrin is a protein that is formed by the action of thrombin on fibrinogen and polymerizes to form a blood clot. Fibrin is a type of hard protein, also known as cellulose. It is the protein (monomer) that remains after thrombin acts on fibrinogen and frees fibrinopeptides A and B, and the general term for polymers (polymers) with this protein as the structural unit. Fibrin is a colorless or white amorphous fibrous elastic solid.
[0003] Blood coagulants are composed of thrombin, alcohol, silica powder, emulsifiers, surfactants, etc., and are suspended liquids. They can be made into vacuum blood collection tubes and injection blood collection tubes. Laboratory personnel can complete operations such as taking blood samples, quickly separating serum, and transferring samples in the same vessel. When using vacuum blood collection tubes with coagulants, fibrin will always precipitate and cause needle blockage. Therefore, a new test tube and its matching blood centrifuge are needed to solve the problem of fibrin precipitation and blockage. Utility Model Content
[0004] The above-mentioned purpose of the utility model is achieved through the following technical scheme: a multifunctional blood centrifuge and its blood collection tube, including a blood centrifuge, the blood centrifuge includes a base, a control seat and a support seat are arranged inside the base, the blood collection tube can be evenly fixed on the control seat, the blood collection tube includes a tube body, an airbag deformation strip is arranged on one side of the tube body, an airbag bag is arranged on the outer side of the airbag deformation strip, a deformation strip is arranged on the inner side of the airbag deformation strip, the deformation strip and the airbag bag are connected through an airway, and a cap is also arranged on the tube body.
[0005] Preferably, a card slot is provided on the support seat, and the air bag bag matches the card slot, and the air bag bag can fix the blood collection tube on the blood centrifuge.
[0006] In summary, the present invention includes at least one of the following beneficial technical effects:
[0007] By adopting a blood collection tube with an air bag deformation strip, while being able to contain the coagulant, if fibrin precipitation occurs after centrifugation, the deformation strip can also be expanded by the air in the air bag bag, and the suction needle can push the deformation strip downward to allow the suction needle to pass smoothly through the fibrin area and reach the plasma area to extract the sample to be tested after centrifugation. This is a device that can maximize the detection accuracy and minimize the interference of the external environment, does not require interference from external equipment, and prevents virus contamination.
