Description

TECHNICAL FIELD

[0001] The utility model belongs to positioning device technical field, concretely relates to a blood cell analysis appearance positioning device. BACKGROUND

[0002] In modern medical examination, blood cell analysis appearance is important equipment for blood detection, in order to improve detection efficiency and accuracy, blood cell analysis appearance usually needs to cooperate with test tube to be used to facilitate automatic blood sample suction and analysis. However, in practical application, how to accurately and stably position test tube to ensure the smooth suction of blood sample has been a technical problem for a long time.

[0003] In prior art, for example, the utility model patent with publication number CN210572322U proposes a blood cell analysis appearance positioning device, which can place test tube, thereby reducing blood spilling, and staff do not have to manually hold test tube, reducing the complexity of work. However, the patent still has some deficiencies in practical application.

[0004] Firstly, the positioning device designed by the patent often cannot well adapt to test tubes of different diameters when placing test tubes. Since there are certain differences in the diameters of test tubes used in the market, if the positioning device cannot adapt to these differences, it may lead to unstable test tube placement, affecting the suction accuracy of blood samples. For example, for test tubes with relatively thin diameters, the positioning device may not provide sufficient clamping force, leading to displacement of test tubes during suction. For test tubes with relatively thick diameters, the clamping device may be too tight, affecting the rapid replacement of test tubes.

[0005] Secondly, the positioning device of the patent fails to provide a function of adjusting the height of test tubes according to the amount of liquid in the test tubes. During blood cell analysis, the needle needs to be accurately inserted into the appropriate position of the liquid in the test tube to suction blood samples. If the amount of blood in the test tube is insufficient or the test tube is placed inappropriately, the needle may not correctly suction blood or suction too much air, affecting the accuracy of analysis results.

[0006] Therefore, in view of the above problems existing in prior art, the utility model proposes an improved blood cell analysis appearance positioning device. UTILITY MODEL CONTENT
