Test tube taking and placing mixing device and sample analyzer

Abstract

The invention discloses a test tube pick-and-place blending device and a sample analyzer, the test tube pick-and-place blending device comprises a rotary power element, a clamping part and a rotary assembly, the rotary power element can rotate along a first rotation direction and a second rotation direction opposite to the first rotation direction, and the rotary assembly is driven by the rotary power element; the clamping part comprises a clamping arm used for clamping a test tube, when the rotary power element rotates in the first rotating direction, the rotary power element applies force to the clamping part through the rotating assembly, the clamping arm is opened to release the test tube, and when the rotary power element rotates in the second rotating direction, the rotary power element drives the rotating assembly and the clamping part to incline and shake together. The test tube taking, placing and uniform mixing device provided by the invention is high in integration level, small in occupied space and low in load cost.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a test tube pick-and-place mixing device and a sample analyzer. Background technique [0002] A sample analyzer is a commonly used sample testing instrument. With the advancement of technology, medical equipment such as sample analyzers are gradually developing in the direction of miniaturization, high precision, and high reliability. [0003] In the detection test, it is usually necessary to use the gripper to pick up the sample test tube, and realize the swing of the sample test tube through the mixing mechanism, so as to realize the mixing of the sample; the current test tube clamping and mixing device needs to be equipped with two sets of driving devices, one One set is used for the grasping action of the sample test tube, and the other set is used for the rotating and mixing action of the sample test tube, which has the problems of bulky structure, high cost, and low reliabil...
