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.

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.

A tube for use in an anesthetic system has an essentially cylindrical housing. More effective take-up of carbon dioxide is achieved by an absorbent for carbon dioxide that is arranged within the tube.

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.

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 anaesthetic device has a manual ventilation bag, a mechanical ventilator and a user interface for setting an operating mode, including mechanical ventilation via the mechanical ventilator and manual ventilation via the manual ventilation bag, and for setting parameter values for the operating mode that has been set. The anaesthetic device further has a remote control for wireless transmission of commands to the user interface. The user interface is adapted to carry out the commands from the remote control only when the anaesthetic device is set for manual ventilation.
