Description
Technical field
The utility model relates to a kind of medical examination instrument, especially relates to a kind of blood viscosity fast detection device.
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.But the instrumentation blood sampling complicated and needs that has medical detection blood viscosity now is very bigger.
Existing blood viscosity measuring method mainly contains capillary method, rotary process, falling bodies method, vibratory drilling method, flat band method etc.The simplest measuring method is the capillary method, i.e. the Pinkevitch viscosity meter.For example: China Patent No. is 98239208.3, denomination of invention is the viscosity meter of " intelligent capillary blood viscosity meter ", it has a glass vertical tube, linking to each other with the vertical tube lower port is connected with the glass capillary of a horizontal positioned, vertical tube and glass capillary all place constant water bath box, be positioned at the glass capillary lower end load measuring sensor is arranged, this sensor transmits signal by the A/D capture card to computing machine, linking to each other with the inlet of glass vertical tube is connected with the plastic cement pipe, links to each other with the plastic cement pipe to be connected with sample introduction pipe, testing tube, to dry up pipe.This novel blood viscometer automaticity height, easy and simple to handle; But, the internal diameter of the capillary that this kind viscosity meter is used is generally a millimeter magnitude, because internal diameter capillaceous is thick, concerning patient, need to extract a large amount of blood during clinical use, general desired blood is more than 10ml, therefore the inapplicable hospital clinical of this instrument is suitable for, the experimental temperature that second deficiency is this instrument is by constant water bath box control, if the scope of measuring temperature than broad, the cost height of calibration cell, volume is big, and also inapplicable hospital clinical is suitable for.For another example: China Patent No. is 200510064206.1, denomination of invention is the blood measuring device of " a kind of measuring instrument of real-time human body blood viscosity ", and this measuring instrument comprises pressure source, woven hose, micron tube, transparent capillary, demarcation liquid container, temperature conditioning unit, DATA REASONING and processing unit, display module, the control module of demarcating liquid are housed; Transparent capillary is in DATA REASONING and processing unit inside, and relative measurement method is adopted in viscosity measurement.The measuring instrument of the real-time human body blood viscosity of this invention has energy clear operation and reading error, characteristics such as accuracy of detection and automaticity height; But this kind measuring instrument also need be provided with temperature conditioning unit etc., so complex structure, operates easy inadequately.
The utility model content
Technical problem to be solved in the utility model be to provide a kind of quick, simple and direct, accurately realize the blood viscosity fast detection device that blood viscosity detects.
The technical solution of the utility model is as follows: the blood viscosity fast detection device of design, its main points are: comprise sample introduction product pin, solenoid valve, baroceptor and peristaltic pump, wherein sample introduction product pin upper end is connected with an end of solenoid valve, the other end of this solenoid valve pipe after testing links to each other with described peristaltic pump, is provided with baroceptor on the detector tube between described solenoid valve and the peristaltic pump; The caliber of described detector tube is greater than the caliber of described sample introduction product pin.
The utility model is at creatively design on traditional blood viscosity pick-up unit complex structure, the accurate basis of detection data portion, the blood storage containers such as sample tube of in the utility model detected blood sample being packed into, close the solenoid valve that is connected between sample introduction product pin and the detector tube, the sample introduction product pin and the detector tube of solenoid valve both sides are isolated, thereby make detector tube form airtight pipeline; Open peristaltic pump, the air in the detector tube is discharged, thereby make air pressure in the detector tube less than atmospheric pressure, detect gaseous tension described detector tube in by baroceptor this moment, when the air pressure in the detector tube reaches setting value, stops peristaltic pump; Open solenoid valve then, blood sample in the blood storage containers such as sample tube enters sample introduction product pin under pressure, detect blood sample by baroceptor and enter the gas pressure change numerical value in the detector tube in the sample introduction product pin process this moment, give computing machine with the sampled data of baroceptor again, calculate the viscosity of blood sample according to formula, the caliber of design detector tube is far longer than the caliber of described sample introduction product pin in the above structure, so, the volume that in computation process, can ignore sample introduction product pin, help the detection of blood viscosity more, data are also more accurate.
Be provided with sample tube below described sample introduction product pin, described sample introduction product pin bottom is stretched in this sample tube, and close described sample tube bottom, this sample introduction product pin lower end, and above structure can be according to the measurement that makes things convenient for blood viscosity.
In order to make baroceptor more reliable with being connected of detector tube, also to be convenient to simultaneously change, described baroceptor is connected with described detector tube through silica gel hose.
Beneficial effect: 1, compare the blood viscosity pick-up unit that traditional employing normal pressure mode detects, the utility model adopts the negative pressure mode to detect, and can save part and detect step, makes detection time faster; 2, the utility model is compared the traditional detection device, does not need more blood sample is detected in the suction detection system earlier again, and so the demand of blood sample consumption has still less been saved the consumption of blood sample; 3, the utility model adopts advanced computer technology to detect, and can collect the variation of air pressure more accurately, makes the viscosity results of calculating more accurate; 4, the utlity model has be skillfully constructed, simple in structure, implement easily, characteristics such as good reliability.
