Abstract
The utility model belongs to medical instruments, and relates to a control technique of an electrolyte analyzer used for detecting blood and urine samples, in particular to a peristaltic pump calibrating device of the electrolyte analyzer. The calibrating device comprises a section of liquid inlet pipe connected to an inlet of a peristaltic pump; a liquid inlet valve is arranged near a sample suction inlet at the front end of the liquid inlet pipe; the liquid inlet pipe between the liquid inlet valve and the peristaltic pump is provided with a section of inspiration branch pipe communicated with the atmosphere; the inspiration branch pipe is provided with an air inlet valve; the liquid inlet pipe is also provided with a photoelectric detector; and a detection point of the photoelectric detector is arranged on the liquid inlet pipe between the inspiration branch pipe and the peristaltic pump. The calibrating device can calibrate the liquid absorption under the unit rotation number of turns before the peristaltic pump is put into the normal detection work so as to ensure the detection accuracy, simultaneously the calibration process can be controlled automatically by corresponding software in a control system, and the calibration process is simple and easy.
Description
Technical field
The utility model belongs to Medical Instruments, relates 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.
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 problem to be solved in the utility model is that a kind of peristaltic pump of electrolytic analysis instrument calibrating installation that can improve the blomelicalbloodgasandelectrolrteanalyzers accuracy of detection is provided.
Peristaltic pump of electrolytic analysis instrument calibrating installation of the present utility model 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.
The liquid absorption that device of the present utility model 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, and calibration process is simple.
Description of drawings
Fig. 1 is the structural representation of the utility model device.
Embodiment
As shown in the figure, device of the present utility model has one section feed tube 2 that is connected on peristaltic pump 1 inlet, near the sample suction inlet of feed tube, be provided with a feed liquor valve 3, to the feed tube between the peristaltic pump 1, one section air-breathing arm 4 that communicates with atmosphere is arranged at feed liquor valve 3, air-breathing arm is by gas admittance valve 5 its break-makes of control, feed tube is provided with photoelectric detector 6, but whether the liquid in the Photoelectric Detection perception feed tube moves to ad-hoc location, and the check point of photoelectric detector 6 is arranged on air-breathing arm 4 to the feed tube between the peristaltic pump 1.
Blomelicalbloodgasandelectrolrteanalyzers with said apparatus is controlled it by control system and is carried out once calibration process automatically before testing each time, and concrete steps are followed successively by:
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.
