Description
Technical field
The present invention relates to in-vitro diagnosis medical equipment field, specially a kind of test paper instrument for detecting blood clotting INR parameters and
Method.
Background technology
In recent years, with the development of laboratory medicine, clinically gradually increase in relation to hemostasis and thrombus detection project, fibrin ferment
Former time (PT) as diagnosis disorders of blood coagulation basic detection project, accurate, reliable testing result to clinical detection with
Observation of curative effect provides valuable index.Result to measure different thromboplastin reagents is comparable, and spy draws state
Border standadized ratio INR（International Normalized Ratio）.With the reference blood plasma measured by thromboplastin with
The ISI values that the PT ratios and agents useful for same of normal plasma mark can calculate INR values.The value of INR is higher, needed for blood clotting
Time it is longer.Apoplexy caused by thrombosis, such as thrombus can be prevented in this way.But if when INR values are very high, just
It will appear uncontrollable bleeding risk.INR can also effectively monitor the effect using anti-freezing " hemodilution " drug simultaneously, such as
Warfarin（Warfarin）.Usually using the apoplexy of anticoagulant therapy prevention atrial fibrillation patient；Also it is used for preventing quiet
The recurrence of arteries and veins thrombus.But once using warfarin, just answer the monitoring INR of regularity.Such as patient it will be appreciated that their blood
Pressure value is the same, they also will be appreciated that oneself warfarin dosage and INR values.
INR parameters, but the generally bulky needs of blood coagulation analyzer detect using blood coagulation analyzer in most of medical institutions
Flushing liquor, holding vessel etc. are equipped with, and expensive, complicated for operation, use is popularized to hemorrhagic and thrombotic diseases patient's household
Also there are certain difficulties.So the device of a detection blood clotting INR parameters simple to operation of exploitation is urgently to be resolved hurrily asks
Topic.
Invention content
The problem to be solved in the present invention is to provide a kind of test paper instrument and method for facilitating detection blood clotting INR parameters.
The present invention is achieved by the following technical solutions：
A kind of test paper instrument for detecting blood clotting INR parameters, including the rectangular support frame horizontal by 45 ° of angles, the stent

INR graduated scales, the pedestal lower end are equipped with the blood collection pond for immersing the blood clotting test strips bottom end, the blood collection pond
Capacity is 0.025ml, and the blood collection pond is equipped with the graduation mark for representing 0.02ml capacity；Protection is provided on the stent
With the transparent outer cover of observation blood clotting test strips.It is so designed that, blood collection pond is put into the blood of the acquisition of 0.02ml, passes through 45 °
The cellular circular hole of the blood clotting reagent paper slip of angle, due to capillary phenomenon principle, blood rises and then solidifies constant corresponding INR
Scale value is exactly what is needed the INR detected values wanted.
Further, the groove of the embedded blood clotting test strips, the groove and the blood are provided on the stent
The bottom perforation of collecting pit, the groove penetrate through the cantilever tip.It is so designed that, facilitates fixed blood clotting test strips, Yi Jichong
Tap touches the blood for absorbing blood collection pond, facilitates and replaces blood clotting test strips.
Further, it is pasted with celluloid fiber hardboard under the blood clotting test strips.It is so designed that, facilitates blood in blood clotting
It is absorbed in test strips, anti-Hemostatic Oral Liquid is sticked on stent cover.
Further, the length of the blood clotting test strips is 50 ~ 60mm, width is 3 ~ 4mm, thickness is 1 ~ 2mm.So set
Meter, size design are reasonable.
The detection method of the test paper instrument of the detection blood clotting INR parameters, specific steps are followed successively by down：
1st, finger finger is wiped with alcohol swab；
2nd, blood needle is taken to take blood on the finger by alcohol wipe with sterile；
3rd, the blood taken in blood needle is injected in blood collection pond, and filled to graduation mark position；
4th, when blood is drawn onto blood clotting test strips from collecting pit, the white surface of paper slip band reddens, and 3min is waited for, until blood
When red in solidifying test strips is unchanged, the reading on INR scales is write down.
It is of the present invention detection blood clotting INR parameters test paper instrument compared with prior art, acquired advantageous effect
It is：The present invention is put into the blood of the acquisition of 0.02ml by blood collection pond, by the cellular circular hole of blood clotting reagent paper slip, by
In capillary phenomenon principle, blood, which rises and then solidifies constant corresponding INR scale values, is exactly what is needed the INR detected values wanted, the instrument
Device is simple in structure, at low cost, and it is accurate to measure, time-consuming short, and reduces the size of blood coagulation detection device, using with more feasible
Property, meet the needs of consumer is to market, convenient for being promoted in family, have wide practical use.
Detection method of the present invention using process is simple, testing result is accurate, meets need of the consumer to market
It asks, convenient for being promoted in family, has wide practical use.
