Platelet function detection system and platelet function detection method employing continuous counting method

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...

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 particular, a sample needs to be repeatedly tested to obtain the test result. Larger consumption of diluent and cleaning solution is required, and more waste liquid is produced

At the same time, the instrument also needs to add a polymerization inducer during the detection, which reduces the detection speed and takes a long time for the detection of the instrument, which brings inconvenience to the user.

[0003] The existing continuous counting platelet function tester for platelet and red blood cell detection needs to dilute the blood sample to about 40,000 times to be suitable for the instrument to effectively detect platelets and red blood cells, and the existing continuous counting platelet function tester uses two dilutions More diluent is often required, and correspondingly more cleaning agent is required,
