Abstract

A medical ventilator has a user interface with a screen adapted to display curves representing function parameters for the medical ventilator, a memory unit for storing target values for the function parameters, and a control unit for controlling the medical ventilator dependent on the target values for the function parameters stored in the memory unit. A simplified method of modifying or programming the medical ventilator is achieved through adaptation of the user interface to register a new curve and/or changes to a displayed curve performed by a user on the screen and to transfer these to the memory unit for storage as new target values for the function parameters.

Claims

1. A medical ventilator system comprising:

a ventilator arrangement adapted for interaction with a patient;

a user interface having a display screen on which curves are displayed representing function parameters for said ventilator arrangement;

a memory in which target values for said function parameters are stored;

a control unit connected to said ventilator arrangement for controlling the ventilator arrangement dependent on the target values stored in said memory; and

said user interface having an input arrangement allowing a user to designate, on said screen, a substitute curve for at least one of said function parameters, selected from the group consisting of a new curve and changes to a displayed curve, said user interface transferring said substitute curve to said memory for storage therein as new target values for said at least one of said function parameters.

2. A ventilator system as claimed in claim 1 wherein said input arrangement allows a user to enter designated points on said screen, and wherein said user interface generates said substitute curve by interpolation between said points.

3. A ventilator system as claimed in claim 1 wherein said user interface comprises a function switch which must be activated to allow said designation of said substitute curve.

4. A ventilator as claimed in claim 3 wherein said function switch is a first function switch, and wherein said user interface comprises a second function switch which, when activated, automatically recovers previously stored target values from said memory.

5. A ventilator system as claimed in claim 1 wherein said screen is an interactive screen, and forms said input unit.

6. A ventilator system as claimed in claim 5 wherein said substitute curve is a curve representing changes to a displayed curve, and wherein said ventilator system comprises a stand-off alone pointer, manipulatable by the user, allowing the user to designate said changes on a curve displayed on said interactive screen.
