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 the 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 the 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:

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 it corresponding to the direction of rotation of the rotary and acknowledge switch, an increase or decrease of the value of the selected parameter is brought about directly via the control unit;

b) a change-over of the set value of the selected parameter into the presetting takes place 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 according to a) with an increased or decreased value, so that a further adjustment of the selected parameter setting is possible; and

d) pressing the rotary and acknowledge switch and keeping it pressed within a first time threshold after one of the steps a) or b) brings about confirmation of the set parameter setting.

2. A process in accordance with claim 1, wherein the selected respiration parameter is the inspiratory pressure and/or the 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 the ratio of the inspiration time to the 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 the 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 the ratio of the first time threshold to the second time threshold is about 1.5:

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

providing an input unit for the input of commands into a control unit controlling the 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 the 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 by pressing the rotary and acknowledge switch and keeping it pressed beyond a preset first time threshold and by subsequently adjusting it corresponding to the direction of rotation of the rotary and acknowledge switch to bring about an increase or decrease of the value of the selected parameter directly via the control unit;

releasing the rotary and acknowledge switch such that a change-over of the set value of the selected parameter into the presetting takes place;

pressing 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 set the parameter selected according to said step of selecting with an increased or decreased value, so that a further adjustment of the selected parameter setting is possible; and

pressing the rotary and acknowledge switch and keeping it pressed within a first time threshold after one of the steps of selecting and releasing the rotary and acknowledge switch to bring about a confirmation of the set parameter setting.

8. A process in accordance with claim 7, wherein the selected respiration parameter is the inspiratory pressure and/or the 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 the ratio of the inspiration time to the 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.

11. A process in accordance with claim 7, wherein the rate of setting is limited to a preset value, corresponding to the change in the respiration parameter or parameters set over time.

12. A process in accordance with claim 7, wherein the first and second time thresholds are in the range of seconds and that the ratio of the first time threshold to the second time threshold is about 1.5:
