Step addition temperature, reaches temperature spot required for haemolysis.The utility model realizes the full-automatic of glycolated hemoglobin analysis
Haemolysis, and ensure that the mixing degree of sample, but occur after can not detecting the waste liquid outlet blocking of haemolysis bottom of pond portion
Spilling.
Utility model content
The utility model is directed to spilling caused by after cannot detecting the blocking of haemolysis pond waste liquid outlet in the prior art
Disadvantage provides a kind of spilling detection device in extracorporeal diagnostic instrument haemolysis pond, can detect the discharge of haemolysis pond waste liquid in time
It is overflowed caused by after mouth blocking.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals:
A kind of spilling detection device in extracorporeal diagnostic instrument haemolysis pond, including haemolysis pond, spilling diversion trench, probe, square wave

It is overflowing in diversion trench, the input terminal of the probe other end and square-wave generator connects, the output end and single-chip microcontroller of square-wave generator
Input terminal connection, square-wave generator is used to being converted to the different direct-to-ground capacitance values of probe into the square wave of different frequency, single-chip microcontroller
The frequency values for reading square wave, the frequency values of square wave are compared with the threshold value of setting, and the frequency values of square wave are lower than the threshold set
After value, the spill over output pin of single-chip microcontroller is high level by low level jump, issues the signal for detecting spilling.
The working principle of the spilling detection device of the utility model are as follows: according to the of different sizes of direct-to-ground capacitance value, square wave hair
Direct-to-ground capacitance value is converted to the square wave of different frequency by raw device, and single-chip microcontroller reads the frequency values of square wave, by the frequency values of square wave with
The threshold value of setting is compared.When overflowing has mixed liquor in diversion trench, the direct-to-ground capacitance value that probe in detecting arrives increases, then can make
The frequency values of square wave are reduced rapidly, and make the frequency values of square wave lower than the threshold value of setting, so that the spill over output of single-chip microcontroller is drawn
Foot is high level by low level jump, issues the signal for detecting spilling.
Preferably, further including haemolysis cell cavity body, haemolysis pond and spilling diversion trench are located in haemolysis cell cavity body, probe one end
The setting of haemolysis cell cavity body is protruded into overflow in diversion trench.
Preferably, probe one end is contacted with the bottom surface for overflowing diversion trench.
The utility model is due to using above technical scheme, with significant technical effect:
When the blocking of the waste liquid outlet in haemolysis pond, the residual waste solution in haemolysis pond cannot be discharged, if continued toward haemolysis
Hemolysin and whole blood sample are added in pond, the mixed liquor of hemolysin, whole blood sample and waste liquid will flow to excessive from haemolysis pond spilling
Out in diversion trench.
The spilling detection device in the extracorporeal diagnostic instrument haemolysis pond of the utility model, which can detect, overflows to spilling diversion trench
The presence of interior mixed liquor, detects whether haemolysis pond is overflowed, and then artificial debugging again, avoids in time due to this
Error diagnosis caused by overflow fault guarantees the accuracy of follow-up test.
