Abstract

A process for setting an anesthesia apparatus or respirator with a control unit controlling the respiration is wherein a) after selecting an input sector for a respiration parameter by pressing the rotary and acknowledge switch and keeping it pressed beyond a preset first time threshold and by subsequently adjusting same corresponding to the direction of rotation of the rotary and acknowledge switch, an increase or decrease in the value of the selected parameter is brought about directly via the control unit, b) the set value of the selected parameter is changed over into the presetting by releasing the rotary and acknowledge switch, c) repeated pressing of the rotary and acknowledge switch and keeping it pressed within a second preset time threshold after releasing the rotary and acknowledge switch according to b) leads to the setting of the parameter selected with an increased or decreased value according to a), so that a further adjustment of the selected parameter setting is possible, d) pressing and releasing the rotary and acknowledge switch within the first time threshold after one of the steps a) or b) brings about the confirmation of the set parameter setting.

Claims

1. A process for setting an anesthesia apparatus or respirator by means of an input unit for the input of commands into a control unit controlling respiration, wherein the input unit is combined with a display unit and wherein the input unit has a keyboard for activating preselected input sectors as well as associated output sectors for respiration parameters and a corresponding value of the parameters, and the input unit is provided with a combined rotary and acknowledge switch, which is in functional connection with the input sectors, the process comprising the steps of:

a) after selecting an input sector for a respiration parameter with the input unit, pressing the rotary and acknowledge switch and keeping the rotary and acknowledge switch pressed beyond a preset first time threshold and subsequently adjusting the respiration parameter starting from a presetting value to a new value corresponding to a direction of rotation of the rotary and acknowledge switch, an increase or decrease of the value of the selected parameter from the presetting value to the new value being directly brought about via the control unit;

b) changing over of the new value of the selected parameter into the presetting value by releasing the rotary and acknowledge switch;

c) a renewed pressing of the rotary and acknowledge switch and keeping the rotary and acknowledge switch pressed within a second, preset time threshold, after releasing the rotary and acknowledge switch according to step b), leads to a setting of the parameter selected at the new value with a further increased or decreased parameter value with a further direction of rotation of the rotary and acknowledge switch, so that a further adjustment of the selected parameter setting to a further new value is possible; and

d) following a release of the rotary and acknowledge switch following either step a) or c), pressing and releasing the rotary and acknowledge switch within the first time threshold after one of the steps a) or b) brings about confirmation of the adjustment of the parameter to either the new value or the further new value.

2. A process in accordance with claim 1, wherein the selected respiration parameter is an inspiratory pressure and/or a positive end expiratory pressure (PEEP) for the respiration.

3. A process in accordance with claim 1, wherein at least one input sector is selected for different respiration parameters, especially concerning a ratio of inspiration time to expiration time.

4. A process in accordance with claim 1, wherein at least one of the respiration parameters selected via its input sector is inversely proportional to the direction of rotation of the rotary and acknowledge switch.

5. A process in accordance with claim 1, wherein a rate of setting is limited to a preset value, corresponding to the change in the respiration parameter or parameters set over time.

6. A process in accordance with claim 1, wherein the first and second time thresholds are in the range of seconds and that a ratio of the first time threshold to the second time threshold is about 1.5:

10.

7. A process for setting an anesthesia apparatus or respirator, the process comprising the steps of:

providing an input unit for the input of commands into a control unit controlling respiration, wherein the input unit is combined with a display unit and wherein the input unit has a keyboard for activating preselected input sectors as well as associated output sectors for respiration parameters and a corresponding value of the parameters, and the input unit is provided with a combined rotary and acknowledge switch, which is in functional connection with the input sectors;

selecting an input sector for a respiration parameter, the respiration parameter having a presetting value;

subsequent to said step of selecting, pressing the rotary and acknowledge switch and keeping it pressed beyond a preset first time threshold;

rotating said rotary and acknowledge switch during said pressing to directly change the actual value or the parameter, via the control unit, from a presetting value to a new value corresponding to a direction of rotation of the rotary and acknowledge switch;

releasing the rotary and acknowledge switch such that a change-over of the actual value or the parameter from the new value back into the presetting value occurs;

making a renewed pressing of the rotary and acknowledge switch and keeping it pressed within a second, preset time threshold after said step of releasing the rotary and acknowledge switch to return to the new value;

further rotating the rotary and acknowledge switch during said step of renewed pressing to set the parameter selected with an increased or decreased value from the new value, so that a further adjustment of the selected parameter setting is possible from the new value to another new value; and

pressing the rotary and acknowledge switch and keeping it pressed within a first time threshold after said step of releasing the rotary and acknowledge switch or after said step of further rotating the rotary and acknowledge switch to bring about a confirmation of a set parameter setting at the new value or at the further new value.

8. A process in accordance with claim 7, wherein the selected respiration parameter is an inspiratory pressure and/or a positive end expiratory pressure (PEEP) for the respiration.

9. A process in accordance with claim 7, wherein at least one input sector is selected for different respiration parameters, especially concerning a ratio of inspiration time to expiration time.

10. A process in accordance with claim 7, wherein at least one of the respiration parameters selected via its input sector is inversely proportional to the direction of rotation of the rotary and acknowledge switch.
