Embodiment Construction

[0056] like figure 1 Shown is the electrochemical detection base 1 of the activated coagulation time of the present embodiment, including a chip inlet 101, above or below the position of the chip inlet 101, a magnetic field changing structure 102 is arranged; the ACT detection chip 2 starts from the The chip inlet 101 is inserted, and the magnetic field changing structure 102 mixes the blood sample and the reaction reagent in the ACT detection chip 2 through the inert magnetic rotating rod 203 .

[0057] The magnetic field changing structure 102 includes a magnet fixing block 10201, and at least two magnets 10202 are respectively placed at different positions on the magnet fixing block 10201. In this embodiment, as Image 6 As shown, two magnets are placed at both ends in the length direction; the magnet fixing block 10201 is driven to rotate by the rotary motion component 103 so that the magnetic field changing structure 102 generates a changing magnetic field.

Abstract

The invention discloses an electrochemical detection base and device for activating blood coagulation time, the base comprises a chip inlet, and a magnetic field change structure is arranged above or below the position of the chip inlet; an ACT detection chip is inserted from the chip inlet, and the magnetic field change structure uniformly mixes a blood sample and a reaction reagent in the ACT detection chip. An ACT (activated coagulation time) detection chip added with a blood sample is inserted from the chip inlet of the base; the magnetic field change structure is arranged above or below the inlet position of the chip, a magnetic field is applied to the chip, the magnetic field change structure can generate a variable magnetic field, and a blood sample and a reaction reagent in the chip are uniformly mixed through the inert magnetic rotating rod in the detection cavity of the chip, so that the reaction is fully carried out, and the accuracy of a detection result is ensured; the problems of hysteresis and poor stability of a detection result are solved.

Description

technical field [0001] The invention belongs to the technical field of rapid detection in vitro diagnostic equipment, and in particular relates to an electrochemical detection base and a device for activating coagulation time. Background technique [0002] For traditional coagulation testing items, the patient's plasma needs to be extracted intravenously into a sodium citrate anticoagulant tube, and after centrifugation as required, the upper layer of plasma is transferred to a large coagulation analyzer for testing. It takes a long time for the test results, and it needs the patient to go to the hospital to complete. Especially for those patients with thrombosis who need to take anticoagulant drugs for a long time, it is time-consuming and labor-intensive to go to the hospital for re-examination. [0003] Chinese patent document CN209690317U discloses a multi-index blood coagulation item detection system, the multi-index blood coagulation item detection system includes a ho...
