Abstract

A respirator is provided with a gas-metering device for respiration gases, a control unit influencing and monitoring the metering of the gas, an input unit connected to the control unit for introducing commands into the control unit, a display unit outputting parameters, a rotary knob changing preselected parameters, and with an acknowledge switch, which takes over the changed parameter as a new set value into the control unit and is actuated by the rotary knob. The display unit is designed as an interactive flat screen with a contact-sensitive surface. Data entry sectors with setting segments and output sectors for parameters to be displayed are provided within the flat screen. The input unit is designed as a keypad arranged on the side of the flat screen. At least preselected data entry sectors on the flat screen can be switched by means of the keypad. The rotary knob and/or the acknowledge switch are/is switched into functional connection with the selected setting segment by touching at least one of the setting segments within a data entry sector.

Claims

1. A respirator, comprising:

a gas-metering device for respiration gases;

control unit means for controlling and monitoring metering of respiration gases;

an input unit, connected to the said control unit means for introducing commands into said control unit means, said input unit including a keypad and an input element;

acknowledge switch means for input of changed parameter as a new set value for said control unit; and

said input unit further comprising parameters display and input means for displaying parameters and changing preselected parameters, said parameters display and input means including an interactive flat screen with a contact-sensitive surface with data entry sectors having setting segments and with output sectors for parameters to be displayed, said data entry sectors including preselected data entry sectors which are switched into an active state on said flat screen by said keypad, said setting segments within said preselected data entry sector being actuatable in said active state and including means for switching one of said input element and said acknowledge switch means into functional connection with said selected setting segment upon actuation.

2. A respirator according to claim 1, wherein said keypad is arranged outside of said flat screen.

3. A respirator according to claim 1, wherein said keypad is arranged within said flat screen.

4. A respirator according to claim 1, wherein said display and input means including said flat screen, said keypad and said acknowledge switch are integrated in a modular operating unit, said gas metering device and said control unit being provided as respirator components, said modular operating unit being pivotable in relation to said respirator components.

5. A respirator according to claim 1, wherein said display end input means including said flat screen, said keypad and said acknowledge switch are integrated in a modular operating unit, said gas-metering device and said control unit being provided as respirator components, said operating unit being provided as a component that is detachable from said respirator components.

6. A respirator according to claim 1, wherein said flat screen is designed as a color screen.

7. A respirator according to claim 1, wherein said preselected data entry sectors include a first data entry sector with respiration parameter-setting segments and a second data entry sector with form of a respiration-setting segments, said actuation means of said form of respiration-setting segment being touch responsive for displaying respiration parameter-setting segments corresponding with the actuated form of respiration-setting segment.

8. A respirator according to claim 7, wherein said respiration parameter-setting segments are represented as setting knobs on said flat screen.

9. A respirator according to claim 7, wherein said form of respiration-setting segments are represented as keys on the said flat screen.

10. A respirator according to claim 7, wherein a set value of a parameter is displayed within said respiration parameter-setting segments.

11. A respirator according to claim 10, wherein said respirator parameter-setting segments include parameter displays, and further comprising means for deriving numerical values forming said parameter displays as suggested values based on body weight of a patient connected to the respirator.
