Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0026] see figure 1 , a test tube blood sample automatic mixing device for blood cell analyzers provided by the present invention mainly includes an X-direction horizontal feeding mechanism, a Z-direction lifting mechanism and a Y-direction mixing mechanism, which are used to drive the test tube to achieve a straight line in the Z direction. Lifting action, linear and horizontal movement in the X direction and rotation and yaw movement around the X axis in the YZ plane.

[0027] The Z-direction lifting mechanism includes a Z-direction motor 1, the Z-direction motor 1 is fixed on one side of the U-shaped main bracket 2, its motor shaft is placed horizontally along the Y direction, and a first synchronous pulley is installed on the motor s...

Abstract

The invention discloses a full-automatic testing tube liquid sample blending device and a hematology analyzer. The full-automatic testing tube liquid sample blending device mainly comprises an X-directional horizontal feeding mechanism, a Z-directional lifting mechanism and a Y-directional uniform mixing mechanism, wherein the X-directional horizontal feeding mechanism is used for driving a test tube to realize linear horizontal movement in an X direction; the Z-directional lifting mechanism is used for driving the test tube to realize linear lifting movement in a Z direction; the Y-directional uniform mixing mechanism is used for driving the test tube to realize rotary deflection movement in a YZ plane around an X axis; the Z-directional lifting mechanism is used for driving upper and lower dragging brackets by a motor and a synchronous belt to do Z-directional vertical lifting movement along a first linear guide rail; the Y-directional uniform mixing mechanism is driven by supporting rods in the upper and lower dragging brackets to do vertical lifting movement on a third linear guide rail; the X-directional horizontal feeding mechanism is used for driving a horizontal movement plate on a second slide block by the motor and the synchronous belt to do the linear horizontal movement on a second guide rail in the X direction; and the Y-directional uniform mixing mechanism is arranged on the horizontal movement plate. With the adoption of the full-automatic testing tube liquid sample blending device, the manufacturing precision requirements are easily reduced, and the cost is low due to few parts and a designed metal plate.

Description

technical field [0001] The invention relates to a clinical testing instrument, in particular to an automatic test tube liquid sample mixing device for a hematology analyzer. Background technique [0002] On clinical testing instruments, such as blood cell analyzers, it is necessary to fully and reasonably mix the blood samples contained in the test tubes in the test tube sample rack before testing and sampling. At present, the main methods for mixing samples in test tubes are manual mixing and mechanical mixing. For blood cell analyzers with automatic sample injection, a fully automatic mechanical mixing device must be provided. [0003] The realization method of existing mechanical mixing device mainly contains from the motion mode: [0004] 1. The test tube rotates around its central axis. The test tube does not need to be separated from the test tube sample rack. The rotating friction wheel presses the test tube cap through the device with a rotating friction wheel, an...
