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...
