Technical Field

[0001] The utility model belongs to the technical field of medical machinery design, and in particular relates to a thromboelastograph detection card socket component. Background Art

[0002] Coagulation analyzers are widely used in the field of POCT coagulation testing, and various indicators have clear clinical and physiological significance. Thromboelastographs have also been widely promoted. Thromboelastogram (TEG) is a graph drawn by a thrombelastometer, which is an indicator that reflects the dynamic changes of blood coagulation (including the formation rate of fibrin, the dissolution state and the firmness and elasticity of the coagulation). Although thrombelastograms have a series of advanced, convenient and innovative features in detection methods, detection processes and detection accuracy, they are based on their inherent characteristics under the premise of their own detection principles. The current thrombelastographs still have a series of shortcomings and deficiencies in terms of patient experience, detection efficiency, and degree of automation, which greatly limits their application prospects in hospitals, professional clinical testing institutions, and especially in the field of patient home health monitoring.

[0003] As a result, blood sample test cards came into being. The Chinese utility model patent (patent number: ZL202022282841.X) discloses a test card for a thromboelastograph, which adopts an integrated and modular design to fix the test reagent in the sample test card, realize the automated operation of the test sample (from the sample injection system to the test chamber), and is used to realize the complete test process of the thromboelastograph on the basis of the existing test principle.

[0004] In summary, in order to enable the test card to be docked with the fully automatic equipment for detection, it is necessary to design a test card socket assembly suitable for connecting the card with the thromboelastography instrument. Utility Model Content

The two ball-head cylindrical pins are used to clamp the horizontal grooves provided at the lower part of the detection card from both sides when the detection card is inserted into the card slot, so as to realize the upper and lower positioning of the detection card.

[0012] Furthermore, a positioning bead is provided on the inner bottom surface of the U-shaped structure of the card slot, which is used to push upward into a spherical groove provided on the bottom surface of the detection card after the detection card is inserted, so as to realize the positioning of the front and rear positions of the detection card.

[0013] Furthermore, the positioning bead is a ball-head positioning bead with a spring.
