Abstract
The utility model relates to a part structure of a medical analyzing instrument, in particular to a glycosylated hemoglobin analyzer photometer bubble eliminating structure comprising a photometer with a colorimetric pool; the inlet of the colorimetric pool is connected with a liquid inlet pipeline through an ion exchange chromatography column and a peristaltic pump; the outlet of the colorimetric pool is connected with a drain pipeline; a bypass pipeline is parallelly connected between the inlet and the outlet of the ion exchange chromatography column; an electromagnetic valve is arranged on the bypass pipeline; the on and the off of the electromagnetic valve can be controlled by a controller; and the controller is provided with a detection signal input end which is connected with a signal output part of the photometer, and a signal output end which can send a control instruction to the peristaltic pump. The glycosylated hemoglobin analyzer photometer bubble eliminating structure can eliminate bubbles in the colorimetric pool of the photometer in glycosylated hemoglobin analysis, so that a detection process is carried out smoothly, and the detection precision is improved.
Description
Technical field
The utility model relates to a kind of modular construction of medical analysis instrument, specifically is that a kind of glycosylated hemoglobin analyser photometer bubble is eliminated structure.
Background technology
Adopt ion exchange chromatography to carry out the glycosylated hemoglobin detecting instrument, effect by peristaltic pump during its work is transported to sample in the canned chromatographic column that Zeo-karb arranged, eluent by filling different ions concentration will be adsorbed in the sample on the resin different glycosylated hemoglobin subfraction gradient elutions and separate again, enter colorimetric pool again, by photometer it is carried out stratographic analysis, determine the concentration of the inferior composition of surveying.In said process, owing to can be dissolved with a spot of gas in sample and the eluent, when sample and eluent under the effect of peristaltic pump certain pressure by behind the ion exchange column, because the unexpected reduction of pressure, dissolved gas in sample and the eluent will be transformed into bubble, discharges from sample and eluent.Or be adsorbed on the tube wall of pipeline, or flow with sample and eluent, when bubble is adsorbed on the tube wall of colorimetric pool light path measurement passage, will the photometric measuring accuracy of contrast colors produce significant impact, make the measuring accuracy reduction or can not accurately measure sample.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of and can in the glycosylated hemoglobin analyser course of work, eliminate bubble in the photometer colorimetric pool, carry out smoothly with the assurance testing process, and improve the glycosylated hemoglobin analyser photometer bubble elimination structure of accuracy of detection.
Structure of the present utility model comprises the photometer that has colorimetric pool, the inlet of colorimetric pool is through ion exchange column, peristaltic pump is connected with input duct, the outlet of colorimetric pool is connected with Drainage pipe, be parallel with a bypass duct between the inlet of described ion exchange column and the outlet, bypass duct is provided with a solenoid valve, solenoid valve can be controlled its opening and closing by a controller, controller has a detection signal input end that is connected with photometric segment signal output, and controller also has the signal output part that can send steering order to described peristaltic pump.
The utility model can receive photometric light intensity voltage detection signal by controller, in time find to be positioned at the bubble on the colorimetric pool passage of light, and after finding bubble in time control electromagnetic valve open the bypass duct of chromatographic column, control flow and flow velocity that peristaltic pump strengthens reagent simultaneously, use process of washing, the bubble that colorimetric pool is measured on the conduit wall washes out, thereby eliminates the influence of bubble to measuring, and improves accuracy of detection; Whole process can be finished in testing process under the control of controller automatically, has guaranteed carrying out smoothly of testing process.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, this structure comprises the photometer 2 that has colorimetric pool 1, the inlet of colorimetric pool is through ion exchange column 3, peristaltic pump 4 is connected with input duct, the outlet of colorimetric pool 1 is connected with Drainage pipe, be parallel with a bypass duct 5 between the inlet of ion exchange column and the outlet, bypass duct is provided with a solenoid valve 6, solenoid valve can be by 7 its opening and closing of control of a controller, controller 7 has a detection signal input end that is connected with the segment signal output of photometer 2, and controller 7 also has the signal output part that can send steering order to peristaltic pump 4.
In the utility model course of work, after the instrument start, at first normal light path light intensity voltage detecting is recorded in the computing machine, when bubble absorption is arranged on the measurement passage of flow colorimetric pond, the light intensity that sees through flow colorimetric pond just decays, thereby the magnitude of voltage that is radiated at the output on the photoelectric sensor of responding to luminosity intensity will diminish, when magnitude of voltage was varied down to certain value, just the bubble that exists influence to measure in the passage was measured in explanation.Therefore, in instrumentation control system, set a voltage range, just can monitor the bubble existence of whether influential measurement.Before each the measurement, the instrument at first measurement passage in contrast colors pond detects, when having the bubble of influence measurement, by the work of controller control peristaltic pump, by strengthening the flow and the flow velocity of reagent, use process of washing, the bubble that colorimetric pool is measured on the conduit wall washes out, and then detects light intensity voltage, if with the error of normal value less than setting, then pass through, otherwise repeat this process until passing through, if 5 times can not by report an error.Thereby eliminate the influence of bubble to measuring.
