摘要： An arrangement for automatic drift compensation in a gas analyzer in which a source of radiation radiates through the gas to be analyzed, and directs the radiation onto a detector. The latter forms an amplified output signal corresponding to the detector output and corresponding to the gas concentration. A signal storage stores the signal corresponding to the output signal of the detector when the gas to be analyzed has a predetermined concentration. A comparator compares the output signal from the detector with the stored signal. The gas analyzer is used for determining the content of a predetermined gas in a mixture of gases exhaled by a patient. A circuit connected between the detector output and the comparator input delivers to the storage a signal during the inspiration phase of the patient.

摘要： A method and apparatus for the re-use of anesthetic gases which are not absorbed by a patient, in inhalation anesthesia make use of an adsorption filter during exhalation, the unused anesthetic gases being subsequently desorbed from the adsorption filter during inhalation, and being reintroduced into the respiration flow to the patient. The exhaled gas is supplied through an absorber for carbon dioxide before it is re-supplied to the patient. The apparatus includes a common line for the delivery and discharge of anesthesia and respiration gases to and from a patient. An adsorption filter for adsorption and desorption of anesthetic gases is arranged in this line. To prevent the carbon dioxide from the exhalation gas of the patient, which is adsorbed in the adsorption material, from being re-supplied to the patient in the next inhalation phase, the common line between the patient and the adsorption filter is at least partially divided into an inhalation branch and an exhalation branch, with an absorber for carbon dioxide disposed in the inhalation branch, sized to match the small amount of carbon dioxide left in the reintroduced gas.

摘要： In a method and apparatus for reducing rebreathing of gas from the dead space (i.e., the volume of used gas, which during expiration has filled the airways and is brought back to the alveus at the following inspiration), at least during the final phase of expiration, a flow of used breathing gas is artificially evacuated from the patient through a gas conduit inserted into the patient's airway, the flow rate of evacuated gas being greater than the flow rate of the expiration gas which is being exhaled by the patient at the time. A flow of breathable gas is simultaneously supplied to the patient through gas conduit inserted in the airway, which may be the same conduit as is used for evacuation or a different conduit.

摘要： An anesthetic system has an external gas reservoir and three gas bellows arranged in the external gas reservoir to alternatingly collect or deliver breathing gas from and to a ventilator unit. In this manner a completely closed system is achieved with minimal consumption of, primarily, anesthetic. The bellows are regulated by a regulatory unit which, via a valve system, can selectively connect a source of drive gas to one or more of the containers in order to compress the gas bellows respectively contained therein. When no drive gas is supplied, each bellows passively expands.

摘要： A number of different parameters related to carbon dioxide output of a patient are routinely determined in ventilator/anaesthetic systems. For this purpose, a ventilator/anaesthetic system for determining carbon dioxide parameters includes a ventilator unit in which a first flow meter is arranged to measure an expired flow of gas, and a carbon dioxide meter is arranged to measure the concentration of carbon dioxide in expired gas. Arranging the carbon dioxide meter in the ventilator/anaesthetic unit minimizes the equipment which must be located in the immediate vicinity of patient, and a faster, more sensitive carbon dioxide meter thus can be used.

摘要： A device for displaying a parameter value has at least one row of light-emitting diodes in which each light-emitting diode has a position input, and the device has a control circuit with address outputs connected to the position inputs. Faults, such as a short-circuit can be detected more easily by an improved interconnection of the address outputs and position inputs such that two adjacent address outputs are connected to two position inputs physically separated by at least one position input.

摘要： An apparatus for the administration of a respiratory gas and at least one anaesthetic to a living being, in which apparatus the anaesthetic is vaporized in a vaporizing unit and is entrained in respiratory gas, acquires a safer and more accurate control of the anaesthetic concentration level by means of a regulating valve which controls the flow of respiratory gas through the vaporizing unit and in that a regulating device controls the regulating valve with such accuracy that a preselected concentration of vaporized anaesthetic in the respiratory gas is substantially fully maintained. To further increase the control of the apparatus it may also be provided with a feedback system for both the anaesthetic concentration level and the total flow.

摘要： A respirator has a bypass gas flow and respective valves in the inspiration and expiration lines for setting the gas flow through these lines. A control unit actuates the valves so that a respiratory cycle is produced and such that the bypass gas flow is maintained during expiration. The expiration pressure is identified by a pressure sensor. When this expiration pressure falls below a prescribed value, a new inspiration phase is triggered. To improve this triggering, the patient gas flow is identified by a flow meter, and the prescribed pressure value is varied dependent on the identified patient gas flow.

摘要： A knob assembly is disclosed for a control unit of a medical apparatus with a front panel. In order to transfer a turning setting movement through the front panel, a feed-through sleeve is rotatably arranged in the front panel and a knob core is movably arranged in the feed-through sleeve. On the control side of the front panel the feed-through sleeve and the knob core are enclosed by a manipulable element which, through application of pressure, can axially move the knob core in the feed-through sleeve. The knob core on the back side of the front panel moves a resilient locking washer from a locking position to an unlocked position so that turning of the manipulable element also will turn the feed-through sleeve. To improve the sealing at the feed-through location, the front panel is provided with a protection plate which is beaded outwards and surrounding the feed-through sleeve, with the manipulable element tightly enclosing the beaded protection.

摘要： An apparatus for the registration of drops in an infusion device has a drip chamber from which fluid is supplied from a reservoir through a tube to a patient, with a drop sensor disposed in the region of the drip chamber. The drop sensor is divided into at least two levels, each level having a processing channel allocated thereto including an amplifier, a comparator and a memory. The outputs of each channel are supplied to a logic unit. As long as signals are supplied by each channel to the logic unit, normal and proper operation is assumed, however, a discriminator unit triggers a fault display or an alarm when a signal from only one channel is present within a predetermined time.
