Detection probe and blood sample detection device

Abstract

The invention provides a detection probe and a blood sample detection device, and belongs to the field of medical blood sample detection equipment. The detection probe comprises a magnetic coding rotor and a sensor PCBA detection board; the magnetic coding rotor comprises a rotor base disk, a voice coil motor magnet and a multipole magnetizing displacement magnet assembly; and the sensor PCBA detection board comprises a PCB circuit board, a voice coil motor driving coil and a linear Hall array sensor. By adoption of the detection probe, the magnetic coding rotor can rotate by regular angles according to the size of the driving current of the voice coil motor driving coil, and the multipole magnetizing displacement magnet assembly cooperates with the linear Hall array sensor to detect the precise position and calculate the change condition of the viscoelasticity of the blood. The blood detection device provided by the invention comprises the detection probe and has the advantages of thedetection probe.

Description

technical field [0001] The invention relates to the field of medical blood sample detection equipment, in particular to a detection probe and a blood sample detection device. Background technique [0002] The viscoelastic coagulation analyzer is an analyzer that monitors the coagulation process from the whole dynamic process of platelet aggregation, coagulation, fibrinolysis, etc. and stability) determine whether it has normal coagulation function. [0003] The blood sample sampling probe is a sensor component that detects the data of the blood coagulation state changing with time. The traditional detection probe uses the rotation of the cup body, and the detection probe suspended by the suspension wire detects the passive rotation angle to detect the coagulation index of the blood. However, the traditional The structure of the sensor probe based on the suspension wire structure must be kept absolutely level when working. The use, installation, commissioning and maintenance...

[0003] The blood sample sampling probe is a sensor component that detects the data of the blood coagulation state changing with time. The traditional detection probe uses the rotation of the cup body, and the detection probe suspended by the suspension wire detects the passive rotation angle to detect the coagulation index of the blood. However, the traditional The structure of the sensor probe based on the suspension wire structure must be kept absolutely level when working. The use, installation, commissioning and maintenance of the instrument are very troublesome, and the volume of the sensor is also large. Due to the mechanical structure, the rotation speed and angle of the blood cup are fixed. not adjustable
