    摘要: The function of a respiration system, with a patient port (1) with connected inspiration branch (3) and expiration branch, is checked. A rebreathing line (9) connects the inspiration branch to the expiration branch. A reservoir (25) is connected to a reservoir port (27) in the rebreathing line. An actuatable control valve (29) is provided in the rebreathing line between the expiration branch and the reservoir port. A pressure sensor (33) is connected to the rebreathing line. A control unit (39) is connected to the control valve and to pressure sensor. The process includes closing the control valve for a preset inspiration time and opening it for a preset expiration time. The value sent by the pressure sensor is detected with the control valve opened during the expiration time and compared with a preset first threshold valve. An error message is generated when the value sent exceeds the first threshold value.

    摘要: 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). A maximum percentage of the breathing gas volume expired via the expiration branch (12) reaches the breathing gas delivery unit (1) and can be displaced from there to the patient (3) via the inspiration branch (10).

    摘要: A respiration system feeds an anesthetic gas having, a density ρgas, with a Y-piece for connection to a patient, with a respiration circuit having an inspiration branch and an expiration branch, which extend away from the Y-piece. A first supply line from a branch in the expiration branch leads to an anesthetic gas discharge valve and a second supply line from the branch leads to a reservoir. A too high pressure, opposing expiration, cannot build up in the expiration branch and losses of anesthetic gas are kept to a minimum. A prestressing device exerts a prestressing force onto the valve body of the anesthetic gas discharge valve against the effect of gravity. The mass mvalve and the prestressing force determine a threshold pressure in the anesthetic gas discharge line that results in an opening of the anesthetic gas discharge valve.

    摘要: 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. An air inlet introduces ambient air into the breathing circuit. The air inlet is arranged between the PEEP valve and the breathing gas delivery. A control is provided at least for controlling the ambient air entering through the air inlet, the breathing gas delivery, the PEEP valve and the breathing gas outlet valve for removing breathing gases from the breathing circuit.

    摘要: 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). A value for the purified rebreathing volume flow abs admitted from the CO2 absorber (8) is determined from the difference I−FG of those values, and a rate of CO2 absorption is determined herefrom on the basis of a preset CO2 concentration value or from a CO2 concentration value measured with a gas sensor in the expiratory branch and integrated over time in order to determine the quantity of CO2 absorbed in the CO2 absorber (8).
