Embodiment Construction

[0024] Such as figure 1 As shown, a cleaning system for a cell analyzer includes a back tank cleaning part, a fluid power source 310 and at least one functional unit cleaning part.

[0025] The rear pool cleaning part is provided with a rear pool inlet 2111 and a rear pool outlet 2112. The rear tank inlet 2111 allows cleaning agents such as diluents to enter the rear tank 211 for cleaning; the rear tank outlet 2112 allows the cleaning agent after cleaning the rear tank 211 to flow out of the rear tank 211.

[0026] The fluid power source 310 communicates with the rear tank inlet 2111 through a rear tank cleaning pipeline 111, and the rear tank cleaning pipeline 111 is provided with a first control valve 121. The fluid power source 310 is used to provide the flow power of the cleaning agent, and a syringe or the like can be used. Since the cell analyzer itself is mostly provided with fluid power components such as syringes, the fluid power source 310 can also share the syringe of t...

Abstract

A cleaning system for a cell analyzer comprises a fluid power source, an afterbay cleaning portion and a functional unit cleaning portion. The afterbay cleaning portion is provided with an afterbay inlet and an afterbay outlet. The fluid power source is communicated to the afterbay inlet through an afterbay cleaning pipeline. The afterbay cleaning pipeline is provided with a first control valve. The afterbay outlet is connected with a discharge pipeline. The discharge pipeline is provided with a second control valve. The functional unit cleaning portion is connected to the afterbay cleaning pipeline and / or discharge pipeline. Because of the features of extremely low cell content and large dilution ratio in the afterbay, the afterbay of a counting chamber can be taken as the cleaning node. The functional unit cleaning portion of the cell analyzer is connected with the afterbay cleaning portion through a pipeline. In a cleaning step, various functional units including the afterbay can be cleaned simultaneously by a cleaning agent without carryover, so that the cleaning efficiency and the cleaning agent utilization are improved. Meanwhile, since a high pressure is needed to clean a gem hole of the afterbay, the functional units of the analyzer having a pressure difference themselves are communicated to the afterbay so as to realize simultaneous cleaning of the functional units and the gem hole.

Description

Technical field [0001] The invention relates to the technical field of medical inspection, in particular to a cell analyzer and its cleaning system. Background technique [0002] The cell analyzer is equipped with a counting cell, which generally includes a front cell and a back cell, and the front cell and the back cell are connected through a gem hole (also called a micropore). In the process of cell analysis, the back tank will be in contact with the tested sample, and it is necessary to clean the back tank with a cleaning agent such as a diluent after each measurement. [0003] At the same time, cell analyzers generally include multiple functional units such as optical detection devices and sampling needles. The optical detection device is an important component for white blood cell classification. The sampling needle is used to collect the sample. It needs to be in contact with the sample during the cell analysis process. Therefore, the diluent must be washed after the analys...
