Leukemia lymphocyte separation and extraction device

Abstract

The invention discloses a leukemia lymphocyte separation and extraction device. The leukemia lymphocyte separation and extraction device comprises a base, a motor and a centrifugal tube, wherein a centrifugal base is arranged on the upper surface of the base; the bottom end of the centrifugal base is rotationally connected with the base through a bearing; tooth blocks are evenly arranged on the outer surface of the centrifugal base; the output end of the motor is sleeved with a driving gear, and the driving gear is meshed with the tooth blocks; the centrifugal tube is arranged on the inner side of the centrifugal base; clamping mechanisms are arranged on the two sides of the bottom end of the centrifugal tube; a vacuum tube is arranged on the inner side of the centrifugal tube; the bottomend of the vacuum tube is sleeved with a fixing barrel, and the outer surface of the fixing barrel is sleeved with a sleeve; a spacer is integrally connected to the inner wall of the bottom end of thesleeve; liquid drainage holes are evenly formed in the lower surface of the sleeve; and a through groove is formed in the outer surface of the sleeve in a penetrating mode. The stability of blood sample adding is improved, and the problem that blood cells are prone to diffusion due to unstable control is solved.

Description

Technical field [0001] The invention relates to the technical field of lymphocyte separation, in particular to a leukemia lymphocyte separation and extraction device. Background technique [0002] Lymphocytes are a type of white blood cells, the smallest white blood cells, which are produced by lymphatic organs, mainly exist in the lymph fluid circulating in the lymphatic vessels, and are an important cellular component of the body's immune response function. [0003] During the treatment of leukemia, it is necessary to extract the lymphocytes in the patient’s blood for analysis. At present, the extraction of blood lymphocytes is by centrifugation. The blood sample PBS mixture is added to the centrifuge tube with the lymphocyte separation solution, so that the blood sample is located in the extraction solution as much as possible In the upper layer, you should not use too much force to allow the blood cells to spread to the lower layer. There is no way to centrifuge and layer, and ...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a leukemia lymphocyte separation and extraction device to solve the above-mentioned background technology that requires staff to manually control the flow rate, the control is not stable enough, it is easy to cause blood cells to spread, and affect the effect of lymphocyte separation.
