Novel lymphocyte separation and extraction device for blood examination

Abstract

The invention discloses a novel lymphocyte separation and extraction device for blood examination, and belongs to the field of medical instruments. The novel lymphocyte separation and extraction device for blood examination comprises a base, wherein a first motor is fixedly mounted in the base, an output shaft of the first motor is fixedly connected with a rotating rod through a coupling, a rotating block is rotationally connected to the top of the base, the top end of the rotating rod penetrates through and is rotationally connected to the top of the base, the top end of the rotating rod is fixedly connected to the bottom of the rotating block, a reagent tube is inserted into the rotating block, a clamping assembly is arranged in the rotating block, and a sealing plug is arranged at the top of the reagent tube. According to the device, the situation that a blood sample is mixed with separation liquid before separation can be reduced, so that the separation effect is guaranteed, meanwhile, lymphocytes can be rapidly extracted in a layered mode, and the situations that supernatant is not completely extracted, lower-layer precipitates are extracted by mistake and the like are reduced.

Description

technical field [0001] The invention relates to the field of medical equipment, and more specifically relates to a novel lymphocyte separation and extraction device for blood testing. Background technique [0002] Lymphocytes (lymphocytes) are a kind of white blood cells, which are the smallest white blood cells. They are produced by lymphatic organs and mainly exist in the lymph circulating in lymphatic vessels. The main executor of immune function is the first-line "soldier" to fight against external infection and monitor cell variation in the body. [0003] In the treatment of leukemia, it is necessary to extract the lymphocytes in the patient's blood for analysis. At present, the blood lymphocytes are extracted by centrifugation. By adding the blood sample PBS mixture into the centrifuge tube with the lymphocyte separation medium, the blood sample is located in the extraction solution as much as possible. In the upper layer, do not use too much force to allow the blood ...

Problems solved by technology

[0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a new type of lymphocyte separation and extraction device for blood testing, which can reduce the occurrence of mixing of blood samples and separation liquid before separation, thereby ensuring the separation effect, and can quickly Lymphocytes are extracted in layers, which reduces the supernatant extraction is not clean, the lower layer of sediment is drawn by mistake, etc. It solves the problem that medical staff use test tubes to inject, and the injection process is easy to cause the blood sample and the separation fluid to be separated due to shaking and too fast injection. Mixing occurs, which affects the separation effect. At the same time, after the centrifugation, the medical staff will extract the supernatant one by one, which is convenient for repeated centrifugation. If the straw is inserted too shallow, the supernatant will not be sucked clean, and if it is inserted too deep, the lower sediment will be sucked together. If the lymphocytes cannot be extracted accurately in layers, it is easy to cause confusion due to sedimentation
