Description
Technical field
The utility model is related to in-vitro diagnosis medical equipment field, specially a kind of test paper instrument of detection blood clotting INR parameters
Device.
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 make different thromboplastin reagents measure is comparable, and spy draws state
Border standadized ratio INR（International Normalized Ratio）.With measured by thromboplastin reference blood plasma 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）.Prevent the apoplexy of atrial fibrillation patient usually using anticoagulant therapy；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
It is equipped with flushing liquor, holding vessel etc., and expensive, complicated for operation, it is universal to hemorrhagic and thrombotic diseases patient's household to use
There is also 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.
Utility model content
Problem to be solved in the utility model is to provide a kind of detection blood clotting INR parameters facilitating detection blood clotting INR parameters
Test paper instrument.
The present invention is achieved by the following technical solutions：
A kind of test paper instrument of detection blood clotting INR parameters, includes the rectangular support frame horizontal by 45 ° of angles, described
White celluloid fiber blood clotting test strips are equipped on holder along its length, the cross section of the blood clotting test strips is circular hole honeycomb
The cross-sectional unit Circularhole diameter of structure, the blood clotting test strips is 0.1mm, and blood clotting test strips side is equipped with and aligns
INR graduated scales, the pedestal lower end is equipped with the blood collection pond for immersing blood clotting test strips bottom ends, the blood collection pond
Capacity be 0.025ml, the blood collection pond be equipped with indicate 0.02ml capacity graduation mark；Guarantor is provided on the holder
The transparent outer cover of shield and observation blood clotting test strips.So design, blood collection pond is put into the blood of the acquisition of 0.02ml, passes through
The cellular circular hole of the blood clotting reagent paper slip of 45 ° of angles, due to capillary phenomenon principle, blood rises and then solidifies constant corresponding
INR scale values are 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 holder
The bottom of collecting pit penetrates through, and the groove penetrates through the cantilever tip.So design, 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.So design, 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：
1, finger finger is wiped with alcohol swab；
2, blood needle is taken to take blood on the finger by alcohol wipe with sterile；
3, the blood taken in blood needle is injected in blood collection pond, and filled to graduation mark position；
When 4, being drawn onto blood clotting test strips from collecting pit when blood, the white surface of paper slip band reddens, and waits for 3min, directly
When red on to blood clotting test strips is unchanged, the reading on INR scales is write down.
Compared with prior art, acquired is beneficial for the test paper instrument of detection blood clotting INR parameters described in the utility model
Effect is：The utility model is put into the blood of the acquisition of 0.02ml by blood collection pond, passes through the honeycomb of blood clotting reagent paper slip
Shape circular hole, due to capillary phenomenon principle, blood rises and then solidifies constant corresponding INR scale values and is exactly what is needed the INR inspections wanted
Measured value, the apparatus structure is simple, at low cost, and it is accurate to measure, time-consuming short, and reduces the size of blood coagulation detection device, using more
With feasibility, meet the needs of consumer is to market, convenient for being promoted in family, has wide practical use.
