It is a kind of implementing procedure figure of the method for clot detection provided by the present application shown in Fig. 2 a.Jie below
During continuing, the clot detection device in conjunction with shown in Fig. 1 a illustrates, and the specific implementation flow of this method is as follows：
Step 200：During being sampled to liquid to be detected, terminal device carries out the pressure in sampling catheter
It periodically detects, obtains the pressure value of each detection.
Specifically, first, refering to fig. 1 shown in a, specimen needle 2 that integrated pump 5 is connected by sampling catheter 4 is by specimen bottle 1
Interior liquid to be detected is drawn, and during absorption, pressure sensor 3 detects the pressure value in sampling catheter 4, and will
Pressure value is sent to terminal device 6.
Refering to fig. 1 shown in b, terminal device is detected the pressure of sampling catheter before sampling, obtains initial pressure
Value, during sampling, is detected according to preset duration, obtains first time pressure value, second of pressure value, third successively
Secondary pressure value ... n-th pressure value.
Wherein, terminal device determines according to the sampling commencing signal of reception and starts to sample, terminate letter according to the sampling of reception
Number, determine that sampling terminates.
Wherein, the duration of pressure value detection is far below the duration of primary sample.For example, pressure value of detection when
A length of 1s, the 100s of the duration of primary sample.
Optionally, the voltage value of detection directly can be sent to terminal device by pressure sensor, can also be by pressure value
Voltage value is converted to, and voltage value is transmitted to terminal device.
Optionally, pressure sensor can be set to inside terminal device, can also be single as a part for terminal device
Solely it is used as a detection device.
Wherein, the type of pressure sensor is various, and e.g., resistance strain gage pressure sensor, semiconductor gauge pressure pass
Sensor, piezoresistive pressure sensor, inductance pressure transducer, capacitance pressure transducer, resonance type pressure sensor and electricity
Appearance formula acceleration transducer etc..
In this manner it is possible to achieve during carrying out primary complete sampling to liquid to be detected, it is each in sampling catheter
A pressure value.
Step 201：Terminal device calculates separately the difference between each pressure value and a upper pressure value, obtains each
Pressure difference.
Specifically, first, terminal device by each pressure value of reception, in memory, (e.g., post by data conversion chip status
Storage) in stored.
Then, terminal device reads pressure value from memory successively, and calculates separately each pressure value and upper one
Difference between pressure value obtains the corresponding pressure difference of each pressure value.
Optionally, terminal device can calculate the corresponding pressure difference of each pressure value after sampling terminates, can also be
During pressure detecting, the corresponding pressure difference of each pressure value is calculated in real time.
Wherein, before being sampled to liquid to be detected, the pressure in sampling catheter is detected, and by acquisition
Design of pressure is initial pressure value, and using initial pressure value as a upper pressure value for first pressure value.
For example, N number of pressure difference variable, respectively a1, a2 ... an.The initial value of each pressure difference variable is 0, is calculated successively
Difference between each pressure value and a upper pressure value, and it is stored in pressure difference variable, a1=first times pressure value-is initially pressed
Force value, second of pressure value of a2=-first time pressure value.
For example, Fig. 1 b show that the pressure detecting schematic diagram one when temperature is 20 degrees Celsius, Fig. 1 c show that temperature is 25
Degree Celsius when pressure detecting schematic diagram two, refering to fig. 1 shown in b, when temperature is 20 degrees Celsius, Pressure maximum value -1810~-
Between 1800, refering to fig. 1 shown in c, when temperature is 25 degrees Celsius, Pressure maximum value is between -1940-1930.Temperature is taken the photograph for 20
The otherness of Pressure maximum value between family name's degree and 25 degrees Celsius is larger.
Fig. 2 b show that the waveform diagram one of the sum of pressure difference when temperature is 20 degrees Celsius, Fig. 2 c show that temperature is
The waveform diagram two of the sum of pressure difference at 25 degrees Celsius, shown in Fig. 2 b, when temperature is 20 degrees Celsius, each pressure difference
The sum of between -70~-55mbar, when showing 25 degrees Celsius refering to Fig. 2 c, the sum of each pressure difference is in -60~-55mbar
Between.Obviously, the sum of each pressure difference when the sum of each pressure difference when temperature is 20 degrees Celsius with temperature is 25 degrees Celsius
Between difference it is smaller.
Further, directly a1 can also be set to the difference between second of pressure value and first time pressure value, according to
It is secondary to analogize, calculate each pressure difference.
Step 202：When terminal device determines the adduction of each pressure difference higher than the threshold pressure difference set, judgement exists solidifying
Block.
In this way, the comparison result by the sum of each pressure difference between threshold pressure difference, judges whether grumeleuse, subtract
Lack influence of the otherness of external environment and detection device to clot detection result, improves the accuracy of clot detection.
Reduce the tedious steps debugged to threshold pressure difference, improves the efficiency of clot detection.
When to clot detection, clot detection can be carried out according to pressure value, it can also be according to the corresponding voltage of pressure value
It is worth and carries out clot detection, in the embodiment of the present application, is only illustrated, be based on for judging that grumeleuse whether there is according to pressure value
Identical principle can also judge whether grumeleuse according to the corresponding voltage value of pressure value.
It further, can also be according to each when terminal device determines that the adduction of each pressure difference is not higher than threshold pressure difference
The adduction of a pressure difference is adjusted threshold pressure difference, so as to according to the threshold pressure difference after adjustment to next sub-sampling
Carry out clot detection.
Optionally, adduction of the terminal device based on each pressure difference, using formula newth=u*a+th*b, to pressure difference
Threshold value is adjusted.
Wherein, newth is the threshold pressure difference after adjustment, and th is current threshold pressure difference, and u is adding for each pressure difference
It is the first weighted value with, a, b is the second weighted value, and a and b are the positive number less than 1.
Further, when terminal device determines that the adduction of each pressure difference is not higher than pressure threshold, each pressure value is calculated
The projected area of the pressure waveform of formation on a timeline is integrated as current pressure, determines current pressure integral higher than default
Integral threshold when, judgement there are grumeleuses.
Step 203：Whether what terminal device judged to store washes needle number higher than default to specimen needle progress grumeleuse cleaning
Otherwise frequency threshold value, executes step 205 if so, thening follow the steps 204.
Step 204：Terminal device sends out alert notice.
When the number for washing needle is more, it may be possible to since the device for washing needle breaks down, send out alert notice
Administrator checks.
Step 205：Terminal device sends out the instruction for carrying out grumeleuse cleaning to specimen needle, and adds to washing needle number
One.
In this manner it is possible to determining there are when grumeleuse, the grumeleuse in specimen needle is discharged, so as to by specimen needle again
It is secondary that liquid to be detected is sampled, without manually being cleaned to specimen needle.
