  • Patent number: 7987849
    Abstract: A method for determining the consumption of a CO2 absorber (8) in a respirator with a rebreathing system, with a fresh gas mixer (1) and with a computing and control unit (10). The rebreathing system has a respiration drive (2), a volume flow sensor (3) located in the inspiratory branch, a CO2 absorber (8) located in the expiratory branch, whose output, combined with that of the fresh gas mixer (1), is fed into the inspiratory branch, a breathing gas escape valve (7) and a breathing gas reservoir (9). The computing and control unit (10) is connected to the fresh gas mixer (1), to the respiration drive (2) and to the volume flow sensor (3) in order to receive signals and send control commands. The fresh gas volume flow FG discharged from the fresh gas mixer (1) and the inspiration volume flow I flowing into the inspiratory branch are determined in the method in the computing and control unit (10).

  • Publication number: 20110061650
    Abstract: An anesthesia device and a process are provided with which a breathing gas, which is present in a breathing circuit and which is especially enriched with an anesthetic, can be removed rapidly and in a cost-effective manner. The breathing circuit comprises an inspiratory breathing gas duct and an expiratory breathing gas duct, for receiving an expired breathing gas, a Y-piece, which is designed as a Y-piece that can be closed, for connecting the inspiratory and expiratory breathing gas ducts with a patient. At least one breathing gas supply system introduces breathing gas into the breathing circuit. A breathing gas outlet duct is provided with a breathing gas outlet valve. A breathing gas reservoir intermediately stores breathing gas. A PEEP valve is arranged upstream of the breathing gas reservoir in the direction of flow of the breathing gas. A breathing gas delivery is arranged downstream of the breathing gas reservoir in the direction of flow of the breathing gas.

  • Patent number: 7726307
    Abstract: An anesthesia system with an anesthetic evaporator can be operated even in case of a defect, particularly in case of a power outage. The anesthetic evaporator (10) and a valve arranged upstream of the anesthetic evaporator (10) are provided, whereby the gas flow through the valve (8) is conveyed completely or partially through the anesthetic evaporator (10) or a bypass line (9) past the anesthetic evaporator (10) in case of operation in accordance with the regulations, while the gas flow takes place only through the anesthetic evaporator (10) in case of a defect.

  • Publication number: 20090020123
    Abstract: A process and system are provided for transmitting monitoring states between respirators. The process includes the detection of and recording of monitoring states of a monitoring unit (5) of at least a first monitoring period (10) of a first respirator (2). There is an assignment of an identification to the monitoring states of the monitoring unit (5) of the at least first monitoring period (10) of the first respirator (2). There is a transmission of the monitoring states of the monitoring unit (5) of the at least first monitoring period (10) of the first respirator (2) to a second respirator (3). This is followed by a setting of the monitoring unit (5) of the second respirator (3) corresponding to the transmitted monitoring states of the monitoring unit (5) of the at least first monitoring period (10) of the first respirator (2). This is then followed by a repetition of steps for the monitoring states of the monitoring unit (5) of each additional monitoring period (10) of the first respirator (2).

  • Publication number: 20080029092
    Abstract: A method for measuring the anesthetic agent consumption in a ventilation system has a breathing circuit which contains a gas mixer (1) and an anesthetic agent metering device (2). The anesthetic agent quantity, which is consumed over a pregiven time interval in the ventilation system, is determined from the sum of the determined anesthetic gas volume flows in the ventilation system which are integrated over the pregiven time interval.

  • Publication number: 20070208267
    Abstract: A device is provided for acoustically reproducing the respiratory function for a respirator, with a patient respiration circuit. The device has a noise generator, a volume flow sensor device, which determines the volume flow in the patient respiration circuit and generates an electric signal representing the volume flow, and a volume flow evaluating unit, which is set up to pick up the volume flow signal and to generate a control signal for the noise generator as a function of this in such a way that an acoustic signal with a loudness rising (falling) with rising (falling) volume flow is generated.

  • Patent number: 6679259
    Abstract: A process and system are provided for controlling a respirator with a breathing circuit (2), an inspiration branch (10) and an expiration branch (12), in which the gas components needed for the respiration are fed in by a fresh gas metering device (20) via a fresh gas line (9), as a result of which at least the amount of breathing gas consumed can be replenished. A breathing gas delivery unit (1) is provided in the inspiration branch (10) and with a volume flow sensor (13) in the expiration branch (12). The fresh gas utilization of the respirator is improved and the process and system reduces the resistances in the breathing circuit (2) for the patient (3) by the breathing gas delivery unit (1) being returned during the phase of expiration at a speed that depends on the volume flow that is measured by the volume flow sensor (13).
