Description

Technical Field

[0002] Biochemical analyzer is one of the commonly used equipment for medical testing and can perform various types of analysis and determination such as timing method and continuous monitoring method. In the process of biochemical analysis and testing, the sample needs to be stirred evenly, and then the stirred sample is taken out for testing. General biochemical analysis samples include: serum, body fluid, urine, cell supernatant, etc. Biochemical analysis samples need to be centrifuged to obtain the supernatant.

[0003] Prior art CN206464086U is a centrifuge used for plasma separation and beating. It is convenient to transport blood to a blood centrifuge cylinder through a delivery tube, and blood addition is convenient. The sealing effect between the centrifuge cover and the blood centrifuge cylinder is good. When the stirring motor and the centrifugal variable frequency motor are started, the blood centrifuge cylinder and the stirring blades rotate in opposite directions, and the blood can be stirred, thereby facilitating the centrifugal treatment of the blood. The centrifuged blood is filtered through the centrifugal filter hole and then flows into the beating chamber. As the beating blades rotate, separation and beating are carried out. The treated blood is output from the drainage pipe and the output pipe, which is convenient for blood experiments.

When different blood samples and detection purposes are required, multiple operations are required, which is time-consuming and laborious. Therefore, it does not meet the existing needs. In this regard, we propose a detection sample stirring device for a biochemical analyzer. Utility Model Content
