Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a blood sample mixer. Background Art

[0002] Genetic testing is a technology that detects DNA through blood, other body fluids, or cells. Genetic testing can be used to diagnose diseases and can also be used to predict disease risks. Gene sampling is required before genetic testing, and blood is the most common test sample. Nowadays, the blood vacuum specimen tube collection method has gradually replaced the traditional syringe blood collection method. The blood vacuum specimen tube collection method has stricter mixing requirements. Usually, the blood is shaken by manual hand shaking or an additional external mixing device. For example, the patent document with announcement number CN213779677U discloses a conveniently fixed turntable blood sample mixer, including a base, a support platform arranged above the base, a turntable rotatably connected to the support platform, and a plurality of fixed components arranged around the surface of the turntable. The fixed components include relatively arranged clamping plates and a connecting portion arranged between the two clamping plates. The connecting portion includes a slider and a return spring. The turntable surface is provided with a plurality of slide grooves relative to the positions of the fixed components. Each slide groove is located between the two clamping plates, and a slider is slidably connected in the slide groove. A return spring is fixedly connected between the two sliders, the lower end of the clamping plate is fixedly connected to the slider, and the upper ends of the two clamping plates are symmetrically provided with injection slopes. The utility model is convenient for fixing the blood sample tube, and can be easily operated by one person, which reduces the labor intensity of the staff and enables the blood sample tube to be accurately clamped in place to avoid the blood sample tube from falling and breaking during the rotation of the turntable. However, during operation, the blood needs to be continuously rotated during mixing to be evenly mixed for easy detection. Manual rotation is not only inefficient and increases the labor burden, affecting the mixing quality, but also is not convenient for the blood in the test tube to flow fully, resulting in poor blood mixing effect. When mixing externally, the blood test overflows due to excessively fast rotation speed. Therefore, it is urgent to design a blood sample mixer to solve the above problems. Utility Model Content
