Apparatus for measuring blood coagulation data, and use method and calibration method thereof

Abstract

An apparatus for measuring blood coagulation data, and a use method and calibration method thereof are disclosed. The apparatus comprises: a movable support part (), a fixed support part (), a connection part (), a rotary shaft (), a magnet (), a Hall element (), and a processing unit (). One end of the movable support part () is fixedly connected to the rotary shaft (), and the other end of the movable support part () is connected to the fixed support part () by means of the connection part (); the movable support part () is fixedly connected to the magnet (); the rotary shaft () is able to rotate relative to the fixed support part () under the driving force of measured blood and drive the movable support part () to rotate; the movable support part () is able to move the magnet () to cause a change in the magnetic field of the magnet (); the Hall element () is connected to the processing unit (); the Hall element () is used for outputting a measurement electric signal according to the magnetic field change of the magnet (); and the processing unit () is used for determining blood coagulation data of the measured blood according to the measurement electric signal. The present apparatus can improve the accuracy in measurement of blood coagulation data.
