摘要:
A process is provided for determining the functional residual capacity (FRC) of the lungs during respiration. An environmentally friendly trace gas is used in a process and system for determining the FRC by using fluoropropanes as a trace gas. Values for the FRC can thus be calculated, resolved for individual breaths, from the expiratory trace gas concentration and the expired breathing gas volume and they can be used for determining the FRC depending on their convergence behavior.

A gas mask and breathing equipment is provided with a circuit for breathing gas and with a heat exchanger (7) cooled by an evaporating agent. The evaporating agent is introduced from an evaporating agent container (8) into the heat exchanger (7) via at least one group of spraying elements (9) and a gas delivery means (11) allows a gas volume flow to flow through the heat exchanger (7).

An incubator or open patient care unit (1) is provided, which can be opened and closed by one or more side panes (2). The side pane (2) or each side pane (2) is equipped with essentially vertical guide elements (3, 4). A drive (10) may be provided with an associated analysis unit (11) for the drive (10), wherein the analysis unit (11) receives sensor and/or switching signals, so that the side pane (2) can be automatically opened and/or closed by a preset time or sensor signal.

A compact combination sensor is provided for physiological parameters, which can be worn behind the ear. The combination sensor has a heat flux sensor (1) for detecting two temperatures (Th1, Th2) for determining the body core temperature (Tc), an acoustic sensor (2) for measuring the heart rate (HR) and for detecting speech signals, as well as a measured signal evaluating unit (4, 5, 7). A communications interface (8) is provided for transmitting the processed data from the measured signal evaluating unit (4, 5, 7) to a communications unit (9) are located in the sensor carrier (11).

A respiration moistener (1) has an inlet (3), into which incoming gas (2) to be moistened can be fed. Vapor (21) is mixed with the incoming gas (2) in a mixing chamber (4). Moistened outgoing gas (5) flows out of an outlet (6). In cases in which the temperature of the incoming gas (2) becomes so high that the temperature of the outgoing gas (5) is above a desired value, the internal desired value is adjusted. The outgoing gas (5) can then cool to the desired value on its way through the inspiration tube (7).
摘要:
An arrangement for measuring the body temperature of a living organism includes a sensor housing containing a first temperature sensor for measuring the skin temperature of the living organism, a second temperature sensor and an evaluation unit. The first temperature sensor is placed on the skin of the body and the second temperature sensor is arranged thermally insulated on the side of the first temperature sensor facing away from the skin and is at a spacing relative to the first temperature sensor. The evaluation unit computes the body temperature in accordance with a pregiven temperature formula which contains a temperature difference from the temperatures measured by the first temperature sensor and the second temperature sensor. A compensation unit is provided in such a manner that a lost heat flow (qsa) is considered which occurs during the measurement operation.

A breathing gas humidifier system for a patient includes a replaceable, closed water reservoir (1) with stable pressure, provided for receiving a water reserve for the breathing gas humidifier system. An intermediate storage unit (4) with water is closed from the environment and is located under the water reservoir. The water reservoir (1) and the intermediate storage unit (4) have a valve (16, 14) each, with one of the valves cooperating with the other valve, so that there is a flow connection between the water reservoir (1) and the intermediate storage unit (4) only when the water reservoir (1) is received in a connector (2) of the intermediate storage unit (4). The intermediate storage unit (4) is connected via a water connection line (5) located below the water level to a heated evaporator chamber (7), which opens above the water evaporating at the boiling point into the breathing gas line to a patient. A gas pressure equalizing line (12) is located between the heated evaporator chamber (7) and the intermediate storage unit (4).
摘要:
A device for measuring the body core temperature of a person contains a structure for firmly wrapping around the upper body of the person. A double temperature sensor is connected with the structure for wrapping around the upper body such that the double temperature sensor is pressed elastically onto the upper body in the state in which it is put on in the area of the sternum. The device for measuring the body core temperature is suitable for the integration of a body core temperature measurement in clothing or chest belt systems.

A hoodless incubator is provided, which supplies both a good microclimate in the area of the patient surface (1) and guarantees good access to the patient at the same time and continuously. The incubator includes a bed (1) and an air jet unit (6) arranged above the bed (1) and directed toward the bed (1). The air jet unit (6) discharges a jacketed impinging jet, formed of an inner, air-conditioned core jet (4) and a non-air-conditioned jacket jet (5) surrounding the core jet (4). The bed (1) is surrounded by a channel-like edge area (9), which is in flow connection with the air jet unit (6) via a first feed channel (13) with a first fan (11) arranged therein and with a heating and humidifying device (12) likewise arranged therein in order to form the air-conditioned core jet (4).
摘要:
The invention is directed to a method for controlling the operating parameters determining the thermal metabolism of a premature or newborn disposed in an incubator. These operating parameters include the incubator air temperature and the incubator humidity. The method is improved in such a manner that the adjustment of the parameters is coupled to the combination thereof optimizing the thermal metabolism without the necessity of a complex multiple step adjustment for each individual parameter. The method is characterized in that a primary control circuit for controlling the first parameter supplies the actual value corresponding thereto as a control parameter to a logic generator which determines a sequence value by means of a logic function. This sequence value is conducted to a secondary circuit as a desired value for the adjustment of the second parameter.
