In a cave, here in Belgium, I found this item from various objects and archives.
I suppose there is a vacuum cleaner / cleaner operations.
There are two groups of two cylinders on a central axis. When we filled two bottles and that axis is rotated so that the bottle is in the air, the system sucks blood into the boutille which is in front of the camera. Once completed, it is change!
When the water rose upper to the lower bottle is rotated so that the axis bottles filled with water are found above.
To clean a wound, we filled water bottle is on the floor and hooked to the hook located at the top of the unit. The water flow alone.
There is a tap at the center of the axis of rotation to move from one action to another.
Does anyone have additional information?
And is what might help me and tell me if in a tent ww2 medical operation, this object would have its place?
There is no reference number or indication "medical dept." ...
great thank you
