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.Type: ApplicationFiled: July 29, 2010Publication date: March 17, 2011Applicant: DRAGER MEDICAL AG & CO.

Publication number: 20090020123Abstract: 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).Type: ApplicationFiled: July 16, 2008Publication date: January 22, 2009Applicant: DRAGER MEDICAL AG & CO.

Patent number: 6679259Abstract: 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).Type: GrantFiled: August 8, 2001Date of Patent: January 20, 2004Assignee: Dräger Medizintechnik GmbHInventor: Ralf Heesch
