Abstract
A care or cleaning device for a medical instrument and a process for determining whether an instrument is connected to one or more coupling devices of the care or cleaning device. Compressed air supplied to each coupling device through a compressed air line causes a backpressure and an increase in the air pressure applied in the compressed air line. If no instrument is connected to a coupling device, then the compressed air can escape through the comparatively large opening in the coupling device and without any great resistance, so there is no increase in the air pressure in the compressed air line. When an instrument is connected, a sensor element senses the air pressure applied in the compressed air line and sends an input signal to a control device. By analyzing the received input signal, the control device detects whether or not the coupling device is occupied by an instrument. In the same way, this process can also be used to differentiate different types of instruments.
