Medical therapy arrangement for applying an electrical stimulation to a human or animal subject
A garment worn by the patient is provided. The garment has a first module electrically connected to a second module. The first module has a first sub-control unit electrically connected to a first electrode and a second electrode placed at a first muscle of the patient and a third electrode and a fourth electrode placed at a second muscle. The sub-control unit is electrically connected to a master unit. The first muscle is stimulated with a first stimulation signal without shortening the first muscle by sending the first stimulation signal to the first electrode placed at the first muscle. The stimulation of the first muscle relaxes the second muscle. A measuring unit (U 1 ) of the master unit determines a first current value flowing from the first electrode through the first muscle to the second electrode and sends the first current value to a central processing unit (CPU).
1. A method for treating a patient, comprising:
providing a garment worn by the patient, the garment having a first module electrically connected to a second module, the first module being provided with a first sub-control unit electrically connected to both a first electrode and a second electrode both placed at a first muscle of the patient and both a third electrode and a fourth electrode both placed at a second muscle, the first sub-control unit being electrically connected to a master unit;
the first sub-control unit receiving an instruction signal from the master unit, the master unit sending a first stimulation signal to the first sub-control unit, the first sub-control unit stimulating the first muscle with the first stimulation signal, based on instructions in the instruction signal by sending the first stimulation signal to the first electrode placed at the first muscle, the first sub-control unit stimulating the first muscle without shortening the first muscle; and
a measuring unit (U 1 ) of the master unit determining a first current value flowing from the first electrode through the first muscle to the second electrode and sending the first current value to a central processing unit (CPU) of the master unit.
2. The method of claim 1 wherein the method further comprises the step of the CPU measuring a voltage signal between the third electrode and the fourth electrode placed on the second muscle.
3. The method of claim 2 wherein the CPU changes a frequency and pulse length of the first stimulation signal.
4. The method of claim 1 wherein the method further comprises the step of the CPU of the master unit sending data with instructions to the first sub-control unit before sending a first stimulation pulse of the first stimulation signal to the first sub-control unit.
5. The method of claim 1 wherein the method further comprises the steps of measuring a voltage drop across a resistor R 1 prior to opening a pulse creating switch SW 1 and then the CPU comparing the first current value to a current reference value and subsequently the CPU increasing a voltage of the first stimulation signal.
6. The method of claim 5 wherein the method further comprises the step of the CPU increasing a voltage of the first stimulation signal when the first current value is below a start current value.
7. The method of claim 6 wherein the method further comprises the step of opening the switch SW 1 when the first current value reaches a stop current value and closing the switch SW 1 when the first current value reaches the start current value that is lower than the stop current value.
8. The method of claim 7 wherein the method further comprises the step of setting a current of the first stimulation signal by allowing the first current value to fluctuate between the stop current value and the start current value.
9. The method of claim 1 wherein the method further comprises the step of switching a polarity of the first electrode and the second electrode.
10. The method of claim 1 wherein the method further comprises the step of the master unit switching the first stimulation signal from being in a voltage mode having a constant voltage to a current mode having a substantially constant current wherein the current is configured to only fluctuate between a start current value and a stop current value.
