Medical device cleaning method and corresponding cleaning device and cleaning apparatus

A cleaning device for cleaning a surface of a medical device, the cleaning device comprising:

• a gas input and a liquid input,
• an atomization chamber including a first input, a second input and an output,
• a gas line fluidly connected between the gas input and the first input of the atomization chamber,
• a liquid line fluidly connected between the liquid input and the second input of the atomization chamber,
• a controller configured to control the gas line and the liquid line so that, during a phase of contaminant removal:
• (a) the gas line allows circulation of gas from the gas input to the first input of the atomization chamber, in order to inject a continuous flow of gas in the atomization chamber through its first input;
• and
• (b) the liquid line allows circulation of liquid from the liquid input to the second input of the atomization chamber, in order to introduce a plurality of successive discharges of liquid in the atomization chamber through its second input, each discharge including a respective amount of liquid, a duration between two successive discharges being strictly greater than zero,
• thereby generating, at the output of the atomization chamber, a cleaning flow comprising, successively over time, liquid droplets suspended in gas, the cleaning flow being intended to be oriented towards the surface of the medical device.
