The quantitative detector adopts the quantitative photoelectricity and can eliminate the error caused in the quantifying process of the fluid with different viscosities, so that the quantifying is more accurate; therefore, the quantitative detector has the advantages of reasonable design, simple structure, easy implementation, convenient operation, good reliability, high detection efficiency, strong generality and the like.
Description
Technical field
The utility model relates to a kind of medical examination instrument, particularly infrared ray photoelectricity formula fluid quantitative pick-up unit.
Background technology
At medical domain, the viscosity of measuring blood and other physiological fluid is the diagnostic means that recent development is got up, and the diagnostic application to difficult and complicated illness such as angiocardiopathy and cancer, knurls is more extensive especially.It is quantitative that the quantitative technique that existing blood viscosity detecting instrument uses is mainly the time, time by the suction sample carries out quantitatively sample, the drawback of this mode is different fluid sample viscosity differences, its flow velocity and its viscosity are inversely proportional to, in the identical time, the flow of the fluid of different viscosities is also different, therefore uses timing mode quantitatively to have bigger error, not only accuracy and reliability do not ensure, and structure comparatively complexity, complex operation, detection efficiency are not high.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of accurate, reliable infrared ray photoelectricity formula fluid quantitative pick-up unit.
The technical solution of the utility model is as follows: a kind of infrared ray photoelectricity formula fluid quantitative pick-up unit, comprise sampling receptacle, sample introduction product pin, light-transmission tube, photoemission cell and photoelectric receiving tube, wherein the lower end of sample introduction product pin is stretched in the sampling receptacle, the upper end of this sample introduction product pin is connected with an end of light-transmission tube, and the other end of light-transmission tube directly or by pipeline is connected with aspirator; Side at described light-transmission tube is provided with photoemission cell, and the opposite side of light-transmission tube is provided with photoelectric receiving tube, and the light of described photoemission cell emission can arrive photoelectric receiving tube by light-transmission tube.
Adopt above technical scheme, detected blood sample is packed in the sampling receptacle, and the lower port of sample introduction product pin is positioned under the liquid level of blood sample.Open aspirator, air in the light-transmission tube is discharged, thereby make air pressure in the light-transmission tube less than atmospheric pressure, the interior blood sample of sampling receptacle this moment enters sample introduction product pin under pressure, when sample flow is crossed light-transmission tube between photoemission cell and the photoelectric receiving tube, can cause that the light intensity by light-transmission tube changes, the light intensity that photoelectric receiving tube is received changes, when the late-class circuit of photoelectric receiving tube detects this variation, stop aspirator, air pressure in the light-transmission tube no longer changes, and blood sample stops to flow into sample introduction product pin, and the sample quilt that therefore flows in the light-transmission tube is quantitative.Compare with traditional time quantitative manner, the utility model is quantitatively more accurate, and good reliability, operates very simple.
As preferably, conveniently to draw materials, described sampling receptacle is test tube or glass cylinder.
The amount of desired blood sample can be reduced on the one hand near the interior diapire of sampling receptacle in the lower end of described sample introduction product pin, on the other hand, can convenient blood sample quantitatively.
Described light-transmission tube is a glass tube, and this glass tube is connected with aspirator by pipeline, and described pipeline is a silicone tube.Light-transmission tube adopts glass tube, and light transmission is good, can accurately reflect the Strength Changes by light, thereby has ensured the effect that blood sample is quantitative; Glass tube adopts silicone tube to be connected with aspirator, can improve the convenience that pipeline connects.
Described aspirator is a peristaltic pump, and peristaltic pump work is slow, accurately and reliably.
Beneficial effect: the utility model adopts photoelectricity quantitative, can eliminate the error that produces in the different viscosities fluid quantitative process, make quantitatively more accurate, have reasonable in design, simple in structure, implement characteristics such as easy, easy to operate, good reliability, detection efficiency height, highly versatile.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, the utility model is made of sampling receptacle 1, sample introduction product pin 2, light-transmission tube 3, photoemission cell 4, photoelectric receiving tube 5, pipeline 6 and aspirator 7, wherein sampling receptacle 1 is test tube or glass cylinder, also can adopt the vessel that other can the splendid attire blood sample.The lower end of described sample introduction product pin 2 is stretched in the sampling receptacle 1, and the interior diapire of close sampling receptacle 1, the upper end of this sample introduction product pin 2 is connected with an end of light-transmission tube 3, light-transmission tube 3 is a glass tube, the other end of light-transmission tube 3 is connected with aspirator 7 by pipeline 6, described pipeline 6 is a silicone tube, and aspirator 7 is a peristaltic pump.Side at described light-transmission tube 3 is provided with photoemission cell 4, and the opposite side of light-transmission tube 3 is provided with photoelectric receiving tube 5, and the light of described photoemission cell 4 emissions can arrive photoelectric receiving tube 5 by light-transmission tube 3.
Principle of work of the present utility model is as follows:
Detected blood sample is packed in the sampling receptacle 1, and the lower port of sample introduction product pin 2 is positioned under the liquid level of blood sample 1.Open aspirator 7, air in the light-transmission tube 3 is discharged, thereby make air pressure in the light-transmission tube 3 less than atmospheric pressure, this moment, sampling receptacle 1 interior blood sample entered sample introduction product pin 2 under pressure, when sample flows through between photoemission cell 4 and photoelectric receiving tube 5, can cause that the light intensity by light-transmission tube 3 changes, the light intensity that photoelectric receiving tube 5 is received changes, when the late-class circuit of photoelectric receiving tube 5 detects this variation, stop aspirator 7, air pressure in the light-transmission tube 3 no longer changes, and blood sample stops to flow into sample introduction product pin 2, and the sample quilt that therefore flows in the light-transmission tube 3 is quantitative.
Although below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic rather than determinate; those of ordinary skill in the art is under enlightenment of the present utility model; under the prerequisite of the utility model aim and claim; can make multiple similar expression; as the light-transmission tube that adopts other transparent material to make; perhaps light-transmission tube directly is connected with suction pump, such conversion all falls within the protection domain of the present utility model.
