Problems solved by technology

For example, due to the need to pre-prepared the polymerization inducer into an aqueous solution during instrument testing and placed it in the instrument, the stability of some commonly used polymerization inducers such as arachidonic acid (AA) and adenosine diphosphate (ADP) after being formulated into aqueous solutions Poor, the storage conditions are harsh, every time it is prepared into an aqueous solution, it will be discarded even if it cannot be used up on the same day, and these aggregation inducers are often expensive, and if they cannot be completely used up, they will often lead to waste
In addition, the existing continuous counting platelet function detector needs to dilute the blood sample in a large proportion for each test, so as to meet the needs of the instrument for platelet detection. In p

Embodiment 1

[0038] Such as figure 1 , Pic 4-1 and Figure 4-2 , in this embodiment, the working principle of the sample suction and transfer unit: first, manually add the same amount of collected blood samples into the control tubes and detection tubes of the special test card 5 and mix them evenly, then put the special test card into the test tube of the instrument Lock position 4: close the first valve V1, open the second valve V2, pull down the first quantitative syringe S1, the diluent R1 enters the first quantitative syringe S1, close the second valve V2, open the first valve V1, the second A certain amount of syringe is pushed up, and the sample suction and transfer unit injects the quantitative diluent into the control tube in the control tube 6 through the sample suction needle N1, and then the sample suction needle N1 moves to the N1-1 and N1-2 positions respectively, respectively to the A certain amount of diluent is added into the first detection tube 7 and the second detect...

Embodiment 2

[0048] The difference between this embodiment and Embodiment 1 is that the sample suction and transfer unit of the instrument sucks part of the blood samples diluted for the first time in each detection tube in turn, performs the second dilution in the sample dilution cup, and then sucks part of the blood sample in the sample dilution cup to the sample testing cup, and after the third dilution in the sample testing cup, the blood sample is tested, and the number of blood sample testing in each experimental well is three times.

Embodiment 3

[0050] The difference between this embodiment and Embodiment 1 is that this embodiment only detects the blood samples in the control tube once, and detects the blood samples in each detection tube once.

Abstract

The invention provides a platelet function detection system employing a continuous counting method. The platelet function detection system comprises a special detection card and a detector, wherein the special detection card is provided with a control tube and more than one detection tube; an aggregating agent is pre-loaded in each detection tube; an anticoagulant is loaded or not loaded in the control tube; the detector comprises a control unit, a sample absorbing and transferring unit, a detection cup, a dilution cup, a diluent adding unit, a sample mixing unit and a cleaning unit; the control unit controls various function units of the detector and carries out analyzing, processing, displaying and transmitting of detection information; the sample absorbing and transferring unit comprises a sample absorbing needle, a quantitative syringe, a connection pipeline, a valve, a sample absorbing needle motion device and the like; the sample absorbing and transferring unit is used for absorbing one part of blood samples from the control tube or the detection tube, transferring the blood samples to the dilution cup, absorbing one part of evenly diluted and mixed blood samples from the dilution cup and transferring the blood samples to the detection cup for detection. In addition, the unit can also be used for diluting and mixing the blood samples from the control tube and the detection tube evenly.

Description

technical field [0001] The invention relates to the field of medical testing, in particular to a continuous counting platelet function detection system and method. Background technique [0002] Compared with other platelet function analyzers in the past, the existing continuous counting platelet function detector has made great progress. But there are certain deficiencies in use. For example, due to the need to pre-prepared the polymerization inducer into an aqueous solution during instrument testing and placed it in the instrument, the stability of some commonly used polymerization inducers such as arachidonic acid (AA) and adenosine diphosphate (ADP) after being formulated into aqueous solutions Poor, the storage conditions are harsh, every time it is prepared into an aqueous solution, it will be discarded even if it cannot be used up on the same day, and these aggregation inducers are often expensive, and if they cannot be completely used up, they will often lead to wast...
