In some aspects, a switching device for a medical apparatus includes a first switching member adapted to select an assigned operating function of the medical apparatus; and a second switching member adapted to permit the selecting of the assigned operating function of the first switching member. The second switching member is adapted such that it has a detection space in which it detects a presence of an operating object; and the first switching member is arranged in the detection space of the second switching member.

Switching devices for medical apparatuses and related systems and methods

A method for generating a flow by a peristaltic hose pump, a generated fluid pressure being limited to 500 mbar and being achieved and maintained without a pressure measurement during operation of the pump. A length of a flexible and elastic pump segment of a hose is adjusted such that, while a roller wheel is stationary, and while the segment is guided under tension around the roller wheel, and when applying a fluid pressure in the range from 10 to 400 mbar to one end of the pump segment, a backflow leakage in the opposite direction to the direction of rotation of the roller wheel is created, and a flow of the fluid of at least 0.01 l/min through the pump segment is obtained, taking into account the backflow leakage. The distance of fixing points of each end of the pump segment to the roller wheel rotation axis is fixed.
