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 respiration humidifier has a metering device (3, 10) and an electrically heated evaporator (4), which is in connection with or can be connected to the metering device (3, 10) on its inlet side (E) and with a respiratory gas channel (5), through which respiratory gas can flow, on its outlet side (A). The metering device (3, 10) feeds the amount of water necessary for humidifying the respiratory gas to a predetermined relative humidity of the respiratory gas at a predetermined respiratory gas temperature to the evaporator (4) per unit of time as a function of the amount of respiratory gas flowing through per unit of time. The evaporator (4) provides water vapor with a temperature above 134.degree. C., which heats the respiratory gas to the predetermined respiratory gas temperature on mixing with the respiratory gas to be humidified.

An incubator with air supply, in which air feed ducts, through which a gas flow heated by a tempering device is introduced ascendingly into the interior space of the incubator, are present on the longitudinal sides of a lying surface. Different temperature zones can be set along the lying surface with the gas flow divided into at least one first gas flow and a second gas flow. Air feed ducts extending along the lying surface (2) are provided as first air feed ducts (11) with a first tempering device (6) and as second air feed ducts (13) with a second tempering device (7). The first air feed ducts (11) and the second air feed ducts (13) are arranged, extending over predetermined sections of the lying surface (2), along the lying surface.
摘要:
A thermotherapy device with a hood (4), two flaps (6, 7) pivotable around hinges (5) for closing longitudinally extending, essentially triangular access opening portions in the hood. The opening has an essentially horizontally extending base edge (15). First access areas (12, 13) with the greatest width are directed to the outside, and second access areas (14), which are arranged opposite the first access areas (12, 13), face each other. Objects can be introduced into the interior space of the incubator with both hands simultaneously, without the climate within the hood (4) being compromised in an unacceptable manner. This is achieved by the access openings being designed as areas passing over into each other in the area of the second access areas (14), as a result of which a contiguous access opening (8) is formed in the hood (4).

A device for generating an aerosol in the course of a respiration gas line, which leads from a respirator to a patient for the patient's artificial respiration. The dead space volume existing during the artificial respiration is minimized, and it is possible to arrange the generating device as close to the patient as possible in the course of the respiration gas line. In the interior space of the respiration gas line, an ultrasound generator unit (11, 12), which has a vibrating surface (14), above which a metering line (16) opens, and predeterminable amounts of the liquid to be atomized are delivered from a metering unit (16) outside the respiration gas line (6).
摘要:
A method of controlling the operating parameters of an apparatus for maintaining the temperature of prematures and newborns is improved in that the operating parameters are determined based on a precise definition of the thermal condition of the patient and that information as to the bodily well-being based on determined sensor actual values for controlling the operating parameters are applied. For solving this task, the control takes place basically with the aid of at least two temperature sensors which measure the core temperature and the peripheral temperature, respectively, of the patient. The logic combination of the temperature signals takes place in such a manner that, in addition to the absolute temperature of one of the two sensors, the temperature difference between the two temperature sensors is simultaneously applied. In this way, it is possible for the first time that the thermal well-being of the patient is applied for controlling the incubator parameters and not only a single temperature.
摘要:
The invention is directed to a transport incubator for accommodating prematures and newborns in a compartment wherein the temperature is controlled by means of an energy store which is in thermal contact with the compartment. The transport incubator is improved in that the energy store is made as small and as light as possible and does not have to be supplied with energy continuously in the operating condition. In addition, the transport incubator can be produced at low cost while utilizing environmentally friendly materials. The energy store is configured as an adsorption vessel containing an adsorption material. For generating the heat to be supplied to the infant compartment, the adsorption vessel can be connected to a supply vessel which contains a fluid which is adsorbing on the adsorbing vessel while giving off adsorption heat.

The invention is directed to an incubator for infants wherein air is supplied from an air supply opening arranged between the side walls of the incubator hood and the supporting member defining a supporting surface for accommodating the infant. The air flows upwardly along the side walls of the incubator hood to form an air curtain arranged in surrounding relationship to the infant. An air return channel conducts the air from the vicinity of the top wall of the incubator hood to an air return space below the supporting member. A blower moves the air through the air return channel and into the air return space from where the air can flow upwardly through the air supply opening. Because of the air curtain, there is a temperature gradient only in the vertical direction; however, in the horizontal direction, the temperature gradient is virtually zero so that all regions of the body of the infant lying on the supporting surface are warmed by air at a uniform temperature. In addition, the formation of condensate in the air return channel is prevented because the air curtain and the air return channel are completely within the space enclosed by the base of the incubator and the incubator hood mounted thereon.

An apparatus for enriching respiratory gas with oxygen, wherein the entire enriched respiratory gas can be taken from an absorber bed and the enrichment concentration is adjustable by action on the total flow through the adsorber and the portion of the total flow in excess of the consumer flow is removable via an outflow, is improved so that adjustment of enrichment concentration and consumer flow independently of each other is possible and the enrichment concentration is maintained also at fluctuating consumer flow. To this end a control circuit for the stabilization of the set enrichment concentration is provided, to which is connected a control section for the adjustment of the consumer flow, and an outflow being is arranged at the junction between the control circuit and the control section.
