摘要： An anaesthesia apparatus has a control unit that controls a gas flow of a flushing gas through at least part of the anaesthesia apparatus so as to flush anaesthetic agent from the apparatus when the apparatus is not connected to a patient. In this way the remaining anaesthetic agent can be removed from the anaesthesia apparatus after use before connecting another patient. Pre-use check of the apparatus can be performed automatically.

摘要： A delivery apparatus for pressurized medical liquids has a primary reservoir that pressurizes a medical liquid therein to a driving pressure, a second reservoir having an inlet connected to receive pressurized liquid from the primary reservoir via a controllable intermediate valve, and an outlet for discharge of the received medical liquid via a controllable dosing valve. A pressure measuring unit measures the pressure in the secondary reservoir and a control unit controls the intermediate valve and the dosing valve by monitoring the operation of the intermediate valve and the dosing valve dependent on the measured pressure value from the pressure measuring unit. The control unit generates a status signal dependent on predetermined rules for measured pressure changes compared with calculated pressure changes.

摘要： A respiratory anesthetic aggregate devised for coupling to a breathing apparatus has an anesthetic gasifier unit that has a breathing gas input port connected to a first point in an inspiratory patient gas delivery path of a breathing apparatus, and a fresh gas output port connected to a second point in the patient gas delivery path downstream the first point. The inspiratory patient gas delivery path is connected via a mainstream connection between the first and second point. Thereby the anesthetic gasifier unit is connected in a sidestream configuration to the patient gas delivery path for adding the gasified anesthetic agent in a desired concentration to the patient gas delivery path at the second point. When aggregate is coupled to a breathing apparatus, a substantially volume neutral delivery of anesthetic agent is provided to the breathing apparatus.

摘要： An anesthetic delivery system has a delivery unit containing a carbon dioxide retaining element and a reversible action anesthetic absorber/desorber for releasably retaining therein at least a portion of a charge of anesthetic agent. An externally accessible first internal flow section in the delivery unit directs gas through the delivery unit first through the anesthetic absorber/desorber and then through the carbon dioxide retaining element, sequentially. An externally accessible second internal flow section directs gas through the delivery unit via the anesthetic absorber/desorber and bypassing the carbon dioxide retaining element.

摘要： In a method, ventilator and ventilator control unit for determining an end-expertorial lung volume (EELV) for a mechanically ventilated patient, a breathing gas is provided to the patient that has a first fixed N2/O2 gas composition, at least until the N2/O2 gas composition in air expired from the patient is constant. At least once, at a first predetermined point in time, the N2/O2 gas composition in the breathing gas is changed to a second fixed composition. The change in the N2/O2 gas composition exhaled by the patient for each breath is measured until a second point in time at which the level of expired O2 in at least two subsequent breadths is substantially stable. The measurement is made downstream of the expiratory tube of the ventilator. The total gas volume is determined for each breath, and the EELV of the patient's lungs is determined based on the change in O2 level between the first and second points in time.

摘要： An anesthetic breathing apparatus has a first gas analyzer arranged to provide gas measurement data related to a first sample point to a control unit that is arranged in a servo or feedback control system configured to adjust delivery of a vaporized anesthetic agent from an anesthetic vaporizer to a delivery point in an inspiratory branch of a breathing circuit of the anesthetic breathing apparatus, The first sampling point is arranged in the breathing circuit downstream and close to the delivery point. A second gas analyzer arranged to be operated in a first mode of operation to provide gas measurement data for patient monitoring, and arranged to be operated in a second mode of operation to provide gas measurement data to the control unit. A switch over unit is fluidly connected to the second gas analyzer, and arranged to switch fluid communication of said second gas analyzer between the first sample point for the second mode of operation and a second sample point for the first mode of operation. The second sample point is arranged in a patient tubing close to a Y-piece at a patient connected to the breathing circuit.
