摘要:
An apparatus for supplying respiratory gas to a patient in which respiratory gas components are metered with great accuracy and sources of error are detected early. The apparatus has metering devices for respiratory gas components which are connected, on the leading side of a mixing chamber volume, to a ring line; a first respiratory gas analyzer on the trailing side of the mixing chamber volume; a second respiratory gas analyzer at a patient connection; a regulating device for the respiratory gas components which controls the delivery of respiratory gas components, as a function of the concentration measured with the second respiratory gas analyzer, in such a way that the difference between a predetermined concentration and a measured concentration at the patient connection is minimized; and means for performing a plausibility comparison between the measured values of the first respiratory gas analyzer and the second respiratory gas analyzer.
摘要:
A device is provided for measuring the differential pressure in anesthetic dispensing devices, with which the differential pressure can be measured between two lines (2, 6) for supplying gaseous components to a mixing site (3). The device has at least one differential pressure sensor (11), which is connected with the lines (2, 6) for supplying the gaseous components. Buffer elements (12, 12′) are integrated in the connection between the lines (2, 6) for supplying the gaseous components and the differential pressure sensor (11).
摘要:
A filling system for an anesthetic evaporator is improved such that an anesthetic-specifically coded adapter neck (5) of a bottle adapter (1) can be introduced into the filler neck of a filling device. An outer polygon (7) is provided on the bottle adapter and an inner polygon designed correspondingly thereto is provided on the filler neck as anesthetic-specific codings.
摘要:
A device for measuring the volume flow or other substance properties of a gas, whose direction of flow can reverse. The arrangement contains a specially designed Y-piece, which is used for branching into direction-dependent flow paths and can be used at the same time for the measurement. Such devices can be preferably used in the area of mechanical respiration.
摘要:
A ventilation system (1, 10) is combined with a measuring method (2, 22, 222) for electric impedance tomography (EIT). Bidirectional data exchange between the two systems is provided. Both the ventilation system (1, 10) and the measuring system (2, 22, 222) have a first and second communications electronic unit (11, 12) each with associated transmitting and receiving means for the bidirectional data exchange.
摘要:
An open patient care unit with a bed (1), with inner and outer air discharge channels (20, 30) extending around the bed (1) at least over some sections, and with at least one air exhaust or a purgative suction unit (4) arranged above the bed (1), wherein the air discharge channels (20, 30) are directed such that they converge toward the air exhaust or purgative suction unit (4), and wherein ambient air delivered via a first fan (6) is discharged from the outer air discharge channels (30), and air, which is conditioned in terms of humidity and/or temperature and is delivered via a second fan (8) from the air exhaust or purgative suction unit (4), is discharged from the inner air discharge channels (20), has the essential advantage that a hood, which is used in incubators, is not used at all, so that switching over between different operating states is not necessary, and cooling down of the patient is thus avoided, but good access is at the same time ensured for the care providers.
摘要:
A holding device for medical instruments at a patient's bed, which are accommodated in suspension components. Holding devices for various medical instruments, such as respirators and accessories, infusion and secretion bags, measuring instruments and disposable articles, are used at patients' beds in many areas. A frequent drawback of prior-art holding devices is that the support at the patient's bed is unstable because the holding devices are suspended only loosely in a rail or handle. The holding device according to the present invention guarantees stable fastening at the patient's bed. It comprises a horizontal crossbeam (1), which is fixed on the sides of a peripheral strap (9) at the foot end of the patient's bed via, e.g., fixing means (3) designed as metal claws. Two vertical suspension carriers (2) with openings (6) for receiving suspension components have suspension sections (5) at their upper ends for suspension on the straps (9). It would also be possible to suspend the suspension sections (5) on a wall rail or cabinet rail.
摘要:
A compact device for supporting respiration is provided making possible a mobile, autonomous, pressure-supported respiration of patients near the lungs with very small dead spaces and flow resistances. The device is especially useful for medical applications. The device includes a rotary compressor (3) with an electric drive motor provided with a filter (7) arranged directly upstream in the direction of flow. The compressor (3) is arranged directly upstream of a breathing mask (2) or a breathing tube. A control unit (6) is provided for setting respiration pressure on a basis of speed of rotation. The control unit (6) is connected to the drive motor of the compressor (3).
摘要:
An electrode belt for impedance tomography shall be improved such that it has a simple design and makes possible good contacting of the electrodes (2) with the body of the test subject to be examined. The electrode belt (1) has at least 16 electrodes (2) on an electrode holder or belt material (3), which is elastic at least in some sections. The belt formed of one or more belt material sections completely surrounds a test subject to be examined on the circumference of the body. Electrode feed lines (63) extend along the electrode holder (3). The electrode feed lines and are connected to a feed line (6) at least at one feed point (4) on the electrode holder (3).
摘要:
A care device and process are provided. The care device has a sensor module (11), which is to be placed directly on the patient (3) for picking up the patient's data, such as temperature, pulse and ECG. A first receiving means (13) is arranged in space in the vicinity of the patient (3) and is designed to pass on the measured data received from the sensor module (11). A mobile part (9) can be removed from the care device and provides wireless communication and a second receiving means (24) for establishing an alternative primary wireless link when the patient is removed from the care device.
