Abstract: A process is provided for controlling at least one parameter of the breathing gas supply of a respirator with a patient connected to it as well as to a corresponding control device. The respiration pressure, the breathing gas flow generated by the respirator as well as the respiration rate may be used as parameters. The process presents the advantage that the control of the current respiration needs of the patient are taken into account by the muscle pressure (PMUS), i.e., the percentage of the airway pressure caused by the patient's own effort, being maintained at a value close to zero. An airway pressure (PAWC) is first calculated for this purpose from previously measured values for the airway pressure (PAW) and the breathing gas flow (d/dt V) and the mechanical parameters resistance (RL) and compliance (C) of the patient's lungs, which were determined therefrom, and this is subsequently compared with the actually measured value for the airway pressure (PAW).

Abstract: A device for controlling the breathing gas flow is provided including a breathing gas block (2), a cover (4) and a valve plate (3) as well as a heating device. Condensation effects are prevented from occurring with the supply of the smallest possible amount of energy by provision of a heating foil (16) as a heating element.

Abstract: The invention relates to a respiration bag (1) which has at least one fold (2, 11) extending annularly over the bag (1). The respiration bag (1) can be bent in along this fold (2, 11). In this way, at least one depression results which leads to a reduced volume of the respiration bag (1). A flip over of the respiration bag from the bent-in position is prevented by sealing lips (10, 12) or additional mechanical holders which are applied from the outside to the at least one fold (2, 11). The respiration bag (1) remains stable in the bent-in position with reduced volume up to an inner pressure of 45 to 50 millibar. In this way, a respiration bag (1) for respiration volumes of different sizes is available in dependence upon, for example, whether respiration is to take place with ambient air or oxygen-enriched air or is dependent upon whether an adult or a child is to be respirated.

Abstract: A reusable anesthetic container (1) has an anesthetic reserve space (2), which is provided with at least one movable wall element (3). The wall element (3) can be caused to follow the liquid anesthetic volume. In one embodiment, the movable wall element (3) is designed as a piston, which is caused to follow the anesthetic volume via a toothed piston rod (9). An elastomer ring is preferably provided on the storage container as a detent pawl for the piston rod (9). The anesthetic container (1) has a first metering element (5), which is actuated inductively by means of a complementary second metering element (6) cooperating with another metering element on the anesthesia apparatus (7) for metering the anesthetic.

Abstract: A valve arrangement is provided with a very short minimum valve adjustment time. This is especially suitable for use in respirators or anesthesia apparatuses for metering gases for respirated patients. It has a valve (3, 4) with a seat (3) and with a valve closing part (4) for adjusting the gas flow rate, an inflow line (1) and a discharge line (2) as well as a drive system (5) for controlling the position of the valve closing part (4) relative to the seat (3). A gas flow rate measuring transducer (8) and a control unit (9) are provided for controlling the drive system (5) by means of a control signal. A velocity measuring transducer (7) for measuring the velocity of the valve closing means (4) relative to the seat (3) is present to provide an output signal used to calculate the control signal (40) for the drive system (5).

Abstract: An evaporator chamber for mixing water vapor with respiratory gas has a supply opening for the respiratory gas, an inlet opening for the water vapor and an outlet opening for the humidified respiratory gas. With the evaporator chamber, an excellent mixing is achieved with the smallest possible structural volume. The evaporator chamber is configured as a hollow body (1) having an essentially circularly-shaped inner wall surface (5). The supply opening (4) on the upper end of the hollow body (1) is arranged in a manner which conducts in the respiratory gas essentially tangentially to the inner wall surface (5). The outlet opening (6) is located at the lower end of the hollow body (1) and the inlet opening (9) lies between the supply opening (4) and the outlet opening (6).

Abstract: An arrangement for supplying a medical apparatus with anesthetic is so improved that, when changing the anesthetic supply vessel (1), the new anesthetic is made available directly and, when there is a malfunction of an anesthetic metering device (2), an exchange is possible in a simple manner. The arrangement includes a supply vessel (1) for the liquid anesthetic (6), a metering device (2) for liquid anesthetic and a pin-and-socket connection (15) between the metering component (2) and a vessel receptacle (3) of a medical apparatus (4). The metering component (2) is electrically drivable and is connected to the supply vessel (1) so as to form a modular unit.

Abstract: A ceiling mount for a medical light shall positions a light body at different points of a treatment table in a simple manner. A bracket system is fastened to a lifting arm that can be actuated by a motor and which has at its free end a bracket guided in parallel for the mounting flange of the bracket system.

Abstract: A system for controlling the heating and temperature monitoring of infant incubators and infant warmers is provided with an incubator or infant warmer space, a heater for heating the space as well as a first temperature sensor and a second temperature sensor. An input device for input of one or more control setting works in conjunction with a control device connected to the heater and to the first temperature sensor and the second temperature sensor. The control device forms a control temperature from an input first skin temperature target control setting for a first patient and an input of a second skin temperature target control setting for a second patient and further patients if present and controls the heater based on a difference between the control temperature and an actual temperature value based on a first actual temperature sensed by the first temperature sensor and a second actual temperature sensed by the second temperature sensor.

Abstract: A process and system is provided for regulating the air temperature in an incubator (3), which accommodates a patient, especially a premature or newborn infant, and which is part of a so-called hybrid device. When the function of the hybrid device is changed over between the two device types of “closed incubator” and “open care unit,” the problem arises that the air temperature set point cannot be maintained and the patient cools down as a consequence. The process uses a heat radiation source (1), which is located outside the incubator (3), which can be closed with a hood (2) that is transparent to the radiated heat. The corresponding value measured by an air temperature sensor (5), which is used as an actual air temperature value, is evaluated by an evaluating and control unit (4) along with a value measured by a body temperature sensor (7).

Abstract: A compact, one-part respiratory flow sensor with a small dead space volume for the simultaneous measurement of both the gas volume flow and the concentration of gas components of the respiratory flow. The respiratory flow sensor has a tubular housing (1) with two opposite windows (2, 3) which are arranged at right angles to the direction of flow and limit the respiratory flow and are formed of a material transparent to infrared radiation. An infrared sensor with an infrared radiation source (4) and with at least one infrared radiation detector (5) is connected to the housing (1). The infrared radiation source (4) irradiates one of the two windows (2, 3) of the housing (1). The infrared radiation detector (5), of which there is at least one, receives the infrared radiation of the infrared radiation source (4) after its passage through the respiratory flow and the two windows (2, 3) limiting the respiratory flow.
