Abstract

A respirator or anesthesia system for respirating a patient (20) includes a gas delivery device (3); at least one gas line (4) for forming a breathing air line system, especially a breathing air circulation system; at least one EMG sensor for detecting the electromyographic muscle activity of the respiratory muscles of a patient (20) being respirated; and a control (9) for controlling and/or regulating the output of the gas delivery device (3) as a function of the detected muscle activity of the respiratory muscles. An adaptation of the part of respiration to the performance capacity of the respiratory muscles of the patient (20) being respirated is made possible without invasive measurement of the electromyographic activity of the respiratory muscles by the at least one EMG sensor being an sEMG sensor (6).

Claims

1. A respirator or anesthesia system for respirating a patient, comprising:

a gas delivery means;

a gas line for forming a breathing air line system;

an electromyographic (EMG) sensor, said EMG sensor non-invasively detecting an electromyographic muscle activity of breathing muscles on a skin surface of a patient to be respirated;

a control means for controlling and/or regulating an output of said gas delivery means as a function of the detected muscle activity of the breathing muscles;

a main unit comprising said gas delivery means;

at least one measuring module connected to said EMG sensor;

two energy storage means; and

a charging and switching unit, said charging and switching unit supplying said at least one measuring module with energy such that at least one of said two energy storage means is electrically separated from an energy supply means of said main unit and said at least one of said two energy storage means is electrically connected with said at least one measuring module during a phase of discharge of said at least one of said two energy storage means and said at least one of said two energy storage means is electrically separated from said at least one measuring module and said at least one of said two energy storage means is electrically connected with said main unit during a phase of charging of said at least one of said two energy storage means.

2. A respirator or anesthesia system in accordance with claim 1, wherein another one of said two energy storage means is electrically connected to said main unit and said another one of said two energy storage means is electrically separated from said at least one measuring module via said charging and switching unit with said at least one of said two energy storage means in said phase of discharge, said another one of said two energy storage means being electrically connected with said at least one measuring module and said another one of said two energy storage means being electrically separated from said energy supply means of said main unit via said charging and switching unit with said at least one of said two energy storage means in said phase of charging.

3. A respirator or anesthesia system in accordance with claim 1, wherein said main unit comprises amain housing, said gas delivery means being arranged in said main housing, said at least one measuring module defining a portable assembly unit, said portable assembly unit being separate from said main unit.

4. A respirator or anesthesia system in accordance with claim 1, wherein said at least one measuring module comprises an analog-digital converter unit, said analog-digital converter unit converting analog electromyographic muscle activity detected by at least one EMG sensor into digital signals.

5. A respirator or anesthesia system in accordance with claim 1, wherein said at least one measuring module comprises a data processing unit and/or an energy supply unit.

6. A respirator or anesthesia system in accordance with claim 5, wherein said energy supply unit comprises at least one battery and/or at least one capacitor as one or more of said two energy storage means.

7. A respirator or anesthesia system in accordance with claim 6, wherein said main unit comprises a charging unit for one or more of said two energy storage means.

8. A respirator or anesthesia system in accordance with claim 5, wherein said energy supply unit comprises at least one power cable and said at least one power cable extends to said main unit for carrying electric current from said main unit to said at least one measuring module and current carried by said at least one power cable is carried at said main unit from said main unit to said at least one power cable with an induction unit with two coils by means of induction.

9. A respirator or anesthesia system in accordance with claim 1, wherein said at least one measuring module comprises at least one MMG sensor and/or at least one acceleration sensor and/or a microphone for detecting the muscle activity of the breathing muscles.

10. A respirator or anesthesia system in accordance with claim 1, wherein said breathing air line system comprises a breathing air circulation system.
