A reusable anesthetic container ( ) has an anesthetic reserve space ( ), which is provided with at least one movable wall element ( ). The wall element ( ) can be caused to follow the liquid anesthetic volume. In one embodiment, the movable wall element ( ) is designed as a piston, which is caused to follow the anesthetic volume via a toothed piston rod ( ). An elastomer ring is preferably provided on the storage container as a detent pawl for the piston rod ( ). The anesthetic container ( ) has a first metering element ( ), which is actuated inductively by means of a complementary second metering element ( ) cooperating with another metering element on the anesthesia apparatus ( ) for metering the anesthetic.

A respiration system is provided with an electrically driven rotary compressor as a gas delivery unit. The system makes a low-noise mounting of the gas delivery wheel possible. The gas delivery wheel can also be washed and sterilized and ensures a reliable separation of the breathing gas from the electric components. The respiration system rotary compressor is mounted magnetically axially and radially during operation.

Respiration system with an electrically driven rotary compressor

A respiratory flow sensor, which is suitable for use near a patient, covers a broad gas volume flow measuring range with a low breathing flow resistance and good, reproducible measured signal quality at the same time. The respiratory flow sensor has a first air resistance body ( ) with a blunt end and with an opposite pointed end. The air resistance body ( ) is arranged between the measuring transducer ( ), of which there is at least one, and the patient-side end (P) of the respiratory flow sensor. The pointed end of the first air resistance body ( ) points toward the measuring transducer ( ). A second air resistance body ( ) with a pointed end is arranged between the measuring transducer ( ), of which there is at least one, and the end of the respiratory flow sensor that is away from the patient. The pointed end of the second air resistance body ( ) also points toward the measuring transducer ( ).

An improved rotary compressor ( ) for respiration systems with breathing gases transported in a closed system. This rotary compressor ( ), which can be washed and sterilized, is has an electrically driven compressor wheel ( ) mounted by means of an aerodynamic gas slide bearing. The gas slide bearing comprises radially and axially loaded surfaces, wherein either the axially loaded surface ( ) of the compressor wheel ( ) or the axially loaded, nonmoving housing surface ( ) has grooves ( ).
