Sampling and washing system

Abstract

The invention relates to a sampling and washing system, and belongs to the technical field of medical detection. The system comprises a waste liquid pool, a first diaphragm pump, a cleaning pool, a sampling needle, a counting pool, a diluter and a second diaphragm pump which are connected by a liquid path, wherein the second diaphragm pump is respectively connected with a cleanout fluid container containing a cleanout fluid and a preservation liquid container containing a preservation liquid through a washing pipeline, both ends of the counting pool are connected with a first electromagnetic valve and a second electromagnetic valve, a third electromagnetic valve is arranged between the diluter and the second diaphragm pump, a fourth electromagnetic valve is arranged between the second diaphragm pump and the cleanout fluid container, a fifth electromagnetic valve is arranged between the second diaphragm pump and the preservation liquid container, and a branch pipeline is further arranged on a pipeline between the third electromagnetic valve and the second diaphragm pump. The branch pipeline is communicated with an inner cavity of the cleaning pool. The system cannot only timely and effectively eliminate dirt attached to the cleaning pipeline, but also has the effect of preserving the pipeline, so that the system is convenient to use and operate.

Description

technical field [0001] The invention relates to the technical field of medical detection, in particular to a sampling flushing system. Background technique [0002] In the analysis of some solutions in the medical industry, such as leucorrhea, urine or other liquids. After the automatic sampling system obtains the solution or sample, it directly sends the solution to the microscope inspection equipment for analysis. However, this time there are the following problems: first, the solution often contains a large amount of particles or viscous substances, which may easily cause pipeline blockage; First, if there is residue in the automatic sampling system, cross-infection of samples will occur; third, the pipeline in the automatic sampling system is a thin pipeline with a small diameter. If the maintenance is not good, rust or local biological reproduction will occur. The operating efficiency and detection accuracy of the analyzer system are adversely affected. Contents of t...
