Specific implementation mode
The specific implementation mode of the present invention is made further detailed by the description to optimum embodiment below against attached drawing
Thin explanation.
When optical method in the prior art measures blood coagulation, due to the influence of optical hardware, although can quickly measure as a result,
But since the damage of optical hardware or the variation of quality cause measurement result deviation even mistake, to ensure highly stable
Optical hardware just needs very big cost.The application is by two methods of scattering light turbidimetry in optical method and turbidimetry
It is integrated, two kinds is calculated as a result, to judge that blood coagulation is examined according to two kinds of results according to scattering data, transmission data to realize
Whether survey is correct, has not only met the quick advantage of optics turbidimetry, but also improve accuracy, it can be determined that whether just testing result
Really.
It specifically includes：A kind of blood coagulation device for quick testing, including shell and cavity, the interior setting cavity of shell are each for accommodating
The components such as kind detection device, including laser emitter, scattering optical receiver, transmission optical receiver, test tube.Laser setting is trying
The side of pipe, the laser after the scattering of blood sample after testing that light scattering detector is sent out for detection laser, transmitted light detector
For detect laser after testing blood sample transmission after laser.Light scattering detector, transmitted light detector pass through AD converter respectively
It is connect with master controller MCU, the master controller MCU is connect with display.
Using light intensity sensor for detecting light intensity, light scattering detector is used for for light scattering detector, transmitted light detector
It detects the luminous intensity after blood sample reflection, scattering and is converted to electric signal, transmitted light detector was being solidified for detecting blood sample
The variation of absorbance in journey, the collected data of the two are sent to master controller after being converted to digital signal by AD converter
In handled and obtained corresponding data, by control display show two kinds respectively as a result, user can be according to two kinds
The difference of hemostasis examination result judges whether testing result is normal, illustrates that the tester goes wrong if difference is excessive.It is main
Controller MCU changes the influence for scattering, transmiting according to blood sample in coagulation process, to judge solidification point according to preset data
Etc. parameters, to realize for blood coagulation detection.And the application is sent out after light using a kind of light source respectively by scattering light, transmitted light
Detect the coagulation results of blood sample, show respectively according to distinct methods obtain as a result, it is so both met detected using optical method
The advantages of result can be quickly obtained, and overcome optical hardware and require height, performance inconsistency occur in optical hardware can not cause
Testing result malfunctions and defect that people can not be known.
Master controller MCU is connect with alarm, and master controller MCU is calculated solidifying according to scattering light, transmitted light respectively
Blood data difference sends out alarm signal when being more than predetermined threshold value.Setting is according to (scattering, transmission) number of not sharing the same light in the host controller
According to the error amount that result of calculation allows, when two kinds of hemostasis examination result differences are more than preset error threshold, at this time due to root
The result difference detected respectively according to scattering light data, transmission light data is excessive, therefore is judged as instrument failure or testing result
Mistake.Master controller sends out alarm at this time, for reminding.Master controller, which only needs to compare testing result, can determine whether to count
The difference of value.Such as one of parameter prothrombin time, it can be determined that the difference of the time obtained by two methods is
It is no to be more than default error to determine whether failure or mistake.
Due to ensure that temperature is stablized in fixed value in blood coagulation test process, temperature control system includes PID controller, heating
Device, temperature sensor, master controller are connect with PID controller, and PID controller is connect with temperature sensor, heater respectively, is added

At 37 degrees Celsius, temperature sensor is used to acquire the temperature of blood sample, master controller for sending out control signal to PID controller,
PID controller according to the preset temperature value control heater work of control signal and obtains real time temperature by temperature sensor,
To which the blood sample temperature ensured in test tube is maintained at 37 degrees Celsius, to meet testing conditions.
Master controller is connect with memory, and memory pre-sets coagulation parameters normal range value.When the result of detection is big
When default normal parameter, it is believed that blood coagulation is broken down, and can judge tester with reference to blood coagulation test result according to normal range (NR)
Coagulation function it is whether abnormal.The normal range value of prothrombin time is such as set to judge whether the result of detection is abnormal.
Identification module identification module is set for identification on the shell of the device or input detection blood sample corresponds to
The identity information of tester, identification module are connect with master controller.Identification module is identification card reader or input
Keyboard.It is corresponding with testing result by the identity information for inputting or identifying, it reduces testing result and causes confusion so that detection knot
Fruit and identity information correspond.
Test device built-in communication module, master controller MCU are connect with communication module, and communication module connects with cloud server
It connects, for blood coagulation test data to be uploaded in cloud server.The intelligent terminal of the corresponding tester of blood examination passes through net
Network accesses server, obtains blood coagulation test data corresponding with identity data.The result of detection is uploaded to by communication module
Cloud server stores, and patient can be inputted according to the corresponding testing result of identity information unique identification by intelligent terminal
Identity information obtains the testing result to match with identity information to access server.Facilitate checking or detecting for detection patient
Patient obtains data and doctor is given to diagnose.
Test tube hole of the setting for holding test tubes in cavity, test tube are fitted close for holding blood sample, test tube hole and test tube
And be removably inserted into test tube hole, it is convenient for changing test blood sample and cleaning test tube.
In order to reduce the fluctuation for the source mass that laser emitter is sent out, the power supply for being laser power supply is to stablize output
Regulated power supply reduces influence of the power-supply fluctuation to optical hardware, the error of test result to caused by.
Obviously present invention specific implementation is not subject to the restrictions described above, as long as using the methodology and skill of the present invention
