[0002] The hematology analyzer needs to use three kinds of reagents: diluent, cleaning solution and hemolyzing agent. When any one of these three kinds of reagents is used up, the instrument will give an alarm after completing the test work of the current sample, which may make The last sample before the alarm was inaccurate due to insufficient reagents

Embodiment Construction
[0021] The following describes in detail the analyzer sample device and sample test method of the present invention with reference to the drawings. Such as figure 1 Shown is a schematic diagram of the liquid path of the analyzer sample device of the present invention. The analyzer sample device of the present invention includes a reagent container 1, a sensor 2, a liquid storage chamber 3, a first solenoid valve 4, a second solenoid valve 5, and Syringe 6.
[0022] The sensor 2, the reservoir 3, the first solenoid valve 4 and the second solenoid valve 5 are connected end-to-end through pipelines 7, 13, 9, 10, and 11 from the reagent container 1 to the syringe 6, of which there is one more The pipeline 8 connects the head end of the liquid storage chamber 3 with the first solenoid valve 4.
[0023] Among them, the first solenoid valve and the second solenoid valve are three-way solenoid valves. The three ends of the first solenoid valve are respectively connected to the second sol...

The invention discloses an analyzer sample apparatus. The analyzer sample apparatus comprises a reagent container and a syringe; and is characterized in comprising a sensor, a liquid storage chamber, a first magnetic valve, and a second magnetic valve which are arranged between the reagent container and the syringe, and are connected end to end via a pipeline successively. The head end of the liquid storage chamber and the first magnetic valve are connected via another pipeline. The invention also provides a reagent testing method of the analyzer sample apparatus. According to the reagent testing method, when it is detected by the sensor that no reagent is in the analyzer sample apparatus, a control circuit is used for reminding that no reagent is in the analyzer sample apparatus; and when the amount of the reagent in the liquid storage chamber is enough for one time of sample count, then the control circuit will allow this time of sample count to be performed continuously. The analyzer sample apparatus and the reagent testing method possesses following advantages: cost is relatively low, detection is reliable, the control circuit is sample, and operation is convenient.
Description
Technical field [0001] The invention relates to a blood cell analyzer, in particular to an analyzer sample device and a reagent testing method. Background technique [0002] The blood cell analyzer needs three reagents: diluent, cleaning solution and hemolytic agent. When any of these three reagents is used up, the instrument will alarm after completing the current sample test work, which may make The last sample before the alarm was inaccurate due to insufficient reagents. [0003] At present, the commonly used method for detecting the presence or absence of reagents in blood cell analyzers is to use liquid path sensors. The liquid path sensors have two types: float type and photoelectric type. When the float type is adopted, when the reagent is in a low position, the instrument detects the signal that the reagent does not exist (float When the liquid level is lowered, the instrument prompts that there is no reagent) and this count has not ended. Reagents are needed for this peri...
