Embodiment Construction

[0009] The working process of a novel platelet multifunctional detector of the present invention is described below in conjunction with the accompanying drawings:

[0010] The instrument automatically sucks the patient's blood sample (1) that has been manually mixed outside the machine into the sample preparation cup (2) inside it, and at the same time, the instrument adds platelet analysis solution (6) to the sample preparation cup (2) to analyze the blood sample. Diluted and stabilized platelets become the sample preparation solution. The sample preparation cup (2) is an inverted triangular or inverted trapezoidal cup, which is kept uniformly shaken and kept at a constant temperature (generally within the range of 20-37°C) during the detection process of the instrument, so that the sample is always in a state of uniform and constant temperature. The instrument draws the quantitatively diluted and mixed sample preparation solution from the sample preparation cup (2) to the sa...

Abstract

The invention discloses a new multifunctional platelet detecting instrument which is a multifunctional detecting instrument with the functions of detecting the number, the volume size and the aggregation rate of platelets. The instrument realizes the function of detecting the aggregation ability (aggregation rate) of the platelets by detecting the changes of the platelets after platelet agonist is added. The blood sample which is not subjected to separation process is directly adopted to detect by the instrument; the operation process is convenient, influencing factor is few, and during the detecting process, the sample processing conditions (temperature, time, dosage of the reagent and so on) is automatically controlled to be consistent by the instrument, so the detection result is more reliable.

Description

1. Technical field [0001] The invention relates to a novel platelet multifunctional detector, which belongs to the field of clinical laboratory medicine. 2. Background technology [0002] Platelet (PLT) detection is of great significance for the diagnosis and prevention of thrombotic diseases. The detection of platelets mainly includes the detection of quantity, volume and function. [0003] At present, the detection of the number, volume and related parameters of platelets such as mean volume (MPV), specific volume (PCT) and volume distribution width (PDW) mainly rely on hematology analyzers. The relatively mature detection method of platelet aggregation ability is photoelectric turbidimetry. This method needs to collect a large amount of blood samples and prepare plasma by centrifugation before detection. The operation of this method is cumbersome, and the stability of the results is affected to a certain extent due to many factors affecting the operation process. 3. C...
