Embodiment Construction
[0049] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the present application.
[0050] examples, but not all examples. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0051] It should be noted that if there are directional indications (such as up, down, left, right, front, back, etc.) involved in the embodiments of the present application, the directional indications are only used to explain a certain posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly.
[0052] In addition, if there are descriptions related to "firs...

The invention provides a uniform mixing device. The uniform mixing device comprises a gripper assembly and a rotating structure. The gripper assembly comprises a first driving mechanism, a first gripper and a second gripper. Wherein the first driving mechanism comprises a mounting seat, a lifting block which is arranged in a sliding manner relative to the mounting seat, a first transmission part and a second transmission part which are connected with the lifting block, and a motor which is arranged on the mounting seat and is used for driving the lifting block to lift, and the first gripper is connected with the first transmission part and is pivoted with the mounting seat; the second gripper is connected with the second transmission part and pivoted with the mounting seat, and the second gripper and the first gripper are arranged in a crossed manner. And the rotating mechanism is used for driving the device to perform uniform mixing action. By means of the mode, the mixing device can prevent test tubes and test tube labels from being damaged in the clamping process, meanwhile, the mode of grabbing the test tubes through opening and closing movement has no obvious acting force on the test tube rack, limiting stop blocks do not need to be arranged on the two sides of the test tube rack, and the structural design of a sample injector is simplified.
Description
technical field [0001] The present application relates to the technical field of biomedical devices, and in particular, to a mixing device and a sample analyzer. Background technique [0002] In the field of modern medical technology, because blood testing and analysis provide many experimental index references, which can play a vital role in the analysis and diagnosis of diseases, the sample analyzer with blood testing is one of the most widely used instruments in hospital clinical testing. one. In blood testing and analysis, blood stratification will make the test results inaccurate. Therefore, in order to ensure the accuracy and stability of the test results, the blood in the test tube should be fully mixed before the blood sample is drawn for testing. In the prior art, the mixing gripper of the sample analyzer relies on the spring or its own elastic deformation to grasp the test tube on the test tube rack or the test tube bottom support for mixing operation, which will ...
