Description
Technical field
The invention belongs to Medical Instruments, relate to the control technology of the blomelicalbloodgasandelectrolrteanalyzers that is used for blood, urine examination, specifically is a kind of peristaltic pump of electrolytic analysis instrument calibrating installation and calibration steps.
Background technology
Blomelicalbloodgasandelectrolrteanalyzers is drawn quantity of sample exactly by peristaltic pump in the course of the work and is detected, the uptake of sample is to calculate a pacing items of testing result, usually the control system of instrument is a uptake of knowing sample by the rotating cycle of peristaltic pump, that is, suppose that peristaltic pump revolves the sample accommodating of being drawn that turns around and fixes.And peristaltic pump to revolve the pairing fixed volume that turns around generally be to obtain an empirical value by initial trial, this volume is in case determine the back and no longer change as controlled variable with regard to being imported in the instrumentation control system.And in fact, after instrument operation a period of time,, peristaltic pump is revolved turn around the sample actual volume of being drawn to change owing to reasons such as material aging, distortion, wearing and tearing, so just reduced the accuracy of detection of instrument.
Summary of the invention
Technical matters to be solved by this invention is, provide a kind of can improve the blomelicalbloodgasandelectrolrteanalyzers accuracy of detection and implementation procedure is simple, to little peristaltic pump of electrolytic analysis instrument calibrating installation and the calibration steps of detection efficiency influence.
Peristaltic pump of electrolytic analysis instrument calibrating installation of the present invention comprises one section feed tube that is connected on the peristaltic pump inlet, near the sample suction inlet of feed tube front end, be provided with the feed liquor valve, feed liquor valve to the feed tube between the peristaltic pump is provided with one section air-breathing arm that communicates with atmosphere, air-breathing arm is provided with gas admittance valve, also be provided with photoelectric detector on feed tube, the check point of photoelectric detector is arranged on air-breathing arm to the feed tube between the peristaltic pump.
Peristaltic pump of electrolytic analysis instrument calibration steps of the present invention is based on above-mentioned peristaltic pump of electrolytic analysis instrument calibrating installation, and this method may further comprise the steps successively:
A. the feed tube front end is immersed in the fluid sample, before normally sucking fluid sample, calibrates peristaltic pump, the feed liquor valve is opened, gas admittance valve cuts out, start peristaltic pump and suck one section fluid sample, when the fluid sample front end arrives the check point of photoelectric detector, send signal by photoelectric detector to control system, the control peristaltic pump quits work;
B. the feed liquor valve cuts out, inlet open restarts peristaltic pump, from this moment, control system writes down the number of effective coils of peristaltic pump, when liquid all during the check point by photoelectric detector, just to signal of control system output, the control peristaltic pump quits work photoelectric detector;
C. the detection signal that provides for twice according to photoelectric detector, control system calculates the turning collar N of this section fixed volume pipeline peristaltic pump of finding time
1, the liquid absorption according to new pump line presets an experience number of turns N who obtains by experiment in control system simultaneously
0, pass through N
0And N
1Ratio produce a correction factor λ, this correction factor is stored in automatically to be used in the control system calculate and obtains peristaltic pump unit and rotate actual liquid absorption under the number of turns, finishes the calibration process before this testing.
Control system can all repeat once above-mentioned step before each testing, get this and detect pairing new correction factor λ.
The liquid absorption that device and method of the present invention can rotate under the number of turns its unit before the normal testing of peristaltic pump input is calibrated, guaranteed the precision that detects, its calibration process can be controlled automatically by corresponding software setting in the control system simultaneously, calibration process is simple, traditional relatively testing process does not produce tangible influence to detection efficiency.
