Description
Technical Field
The invention relates to a sample analyzer, in particular to a reagent sucking method and a reagent sucking device of the sample analyzer.
Background
The full-automatic sample analyzer is used for analyzing samples from a tested body and is characterized by high automation degree and high testing speed. In some hospitals, some items have a large daily test quantity, so the quantity of various reagents used in the test items is also large, and in order to ensure the continuity of the test, doctors usually place multiple bottles (hereinafter referred to as multiple bottles) on the instrument for the same reagent, and the instrument software determines which bottle of reagent is sucked in advance through a default sucking order. For example, three bottles of the same reagent are placed on the reagent tray, and the instrument software defaults that the reagent is sucked in the order of small to large cup coordinates.
In view of the differences in the reagent storage and dispensing operations at each hospital, a doctor may choose an overdue reagent or calibrate an overdue reagent during the reagent dispensing process. In such a case, the physician will typically wish to administer the overdue reagent first, or the calibration parameters will be overdue first. In the manner in which the instrument software autonomously determines the aspiration sequence, the physician does not have sufficient authority to select the reagent aspiration sequence, which may result in the physician wasting more expensive reagents or performing more complex calibration procedures.
