Embodiment 2

[0091] In the second embodiment, the preset signal value Vj is calculated according to the signal value corresponding to the maximum amplitude of the steel ball within the second preset time from the start of the blood coagulation detection timer, so that the blood coagulation time measurement result is more accurate.

[0092] see Figure 6 , Figure 6 It is a flow chart of the blood coagulation time measurement method disclosed in Embodiment 3 of the present invention. Steps S61-S66 and S62a-S62b in Embodiment 3 are the same as steps S51-S56 and S52a-S52b in Embodiment 2. For details, please refer to Embodiment 2 Content. The difference between the third embodiment and the second embodiment is that steps S62c and S62d are also included after step S62b.

[0093] Step S62c: Compare the steel ball amplitude value indicated by the currently acquired signal value with the steel ball amplitude value indicated by the reference signal value, if the steel ball amplitude value indica...

Embodiment 7

[0110] In Embodiment 7, the second acquisition unit 109 may include a comparison module and a recording module, the comparison module is used to compare the steel ball amplitude values ​​indicated by the signal values ​​obtained twice adjacently within the second preset time, and the recording module records the two adjacent Among the signal values ​​acquired for the first time, the signal value indicating the larger amplitude value of the steel ball is compared. The recording module updates the recorded signal value according to the comparison result of the comparison module each time the comparison module compares. Finally, the signal value recorded by the recording module is the reference signal value.

[0111] Please refer to Figure 11 , Figure 11 It is another coagulation time measurement device disclosed in Embodiment 8 of the present invention, which adds a third comparison unit 111 , a fourth control unit 112 and an update unit 113 on the basis of the coagulation ti...

Abstract

The invention discloses a blood coagulation time measuring method, device and system. The blood coagulation time measuring method comprises the steps of in response to a starting instruction, startingblood coagulation detection timekeeping; obtaining a signal value used for indicating a steel ball amplitude; comparing the steel ball amplitude indicated by the signal value with a steel ball amplitude indicated by a preset signal value; recording the lasting time when the steel ball amplitude indicated by the signal value is smaller than the steel ball amplitude indicated by the preset signal value; if the lasting time is larger than or equal to a first preset time, stopping blood coagulation detection timekeeping. The blood coagulation time measuring method can effectively solve the problem that a blood coagulation time measuring result is smaller than an actual result.

Description

technical field [0001] The invention relates to the technical field of blood coagulation analysis experiments, and more specifically, to a method, device and system for measuring blood coagulation time. Background technique [0002] At present, the steel ball method is generally used for the determination of coagulation time. During measurement, drive coils and detection coils are respectively arranged on both sides of the test cup, wherein the drive coils are used to generate a constant alternating magnetic field to make the steel balls in the test cup swing, and the detection coils are used to generate signals indicating the amplitude of the steel balls. Add the coagulation activator to the blood in the test cup and start timing. As the fibrin in the blood increases, the blood viscosity increases, causing the amplitude of the steel ball to gradually decrease until the amplitude of the steel ball indicated by the signal value generated by the detection coil is lower than th...
