Cleaning device for nozzle system of flow cytometer and cleaning method

Abstract

The invention discloses a cleaning device for a nozzle system of a flow cytometer and a cleaning method. The cleaning device comprises a flow cytometer shell, a cleaning box and a sample tube, and the side wall of the sample tube is communicated with a threaded tube; a conveying pipe is arranged in the cleaning box, one end of the conveying pipe penetrates through the cleaning box to be connected with a mounting part, the mounting part is used for communicating the conveying pipe with the threaded pipe, a temperature control part and a flow detection part are arranged on the side wall of the conveying pipe, and a cleaning agent self-switching part and an air source part are arranged in the cleaning box; a cleaning agent circulating device is arranged on the side wall of the cleaning box and comprises a shunting part arranged at the liquid discharge end of the flow cytometer shell, a water quality detection part which is arranged on the outer wall of the cleaning box and is connected with the shunting part through a circulating pipe, and a circulating part which is arranged on the inner wall of the cleaning box and is used for circularly discharging liquid in the water quality detection part into the conveying pipe. According to the cleaning device and the cleaning method, the sample tube and the nozzle system of the flow cytometer can be conveniently cleaned together.

Description

technical field [0001] The invention mainly relates to the technical field of medical equipment cleaning, in particular to a cleaning device and a cleaning method for a nozzle system of a flow cytometer. Background technique [0002] Flow cytometry can quickly measure, store, and display a series of important biophysical and biochemical characteristic parameters of dispersed cells suspended in liquid, and can sort specified cell subgroups from them according to the pre-selected parameter range come out.
