Muscle stimulation device

摘要

A surface NMES stimulation device the device has a control processor, a voltage regulator connected to a high voltage supply, a bridge of control switches, and electrodes or electrode terminals connected in the bridge to receive drive signals via the control switches. The processor directs a drive scheme for the bridge control switches in which charge build-up on a user's skin is allowed to dissipate to ground in an inter-pulse interval. An isolation capacitor isolates the high voltage supply from the electrodes, and charging of the capacitor only occurs if a switch allows it. Sensors senses supply voltage and bridge current and the processor monitors there to determine further stimulation and faults.

1. A surface neuromuscular electrical stimulation device comprising:
a voltage regulator connected to a high voltage supply, a bridge of control switches including top switches and bottom switches, a control processor configured to direct drive signals for the bridge of control switches, electrode terminals connected in the bridge to receive the drive signals via the control switches, a ground connected to the electrode terminals, and at least one isolation capacitor configured to isolate the high voltage supply from the electrode terminals, wherein the control processor is configured to direct the drive signals for the bridge of control switches in which charge build-up on the electrode terminals is allowed to dissipate to the ground in an inter-pulse interval, and wherein the top switches are linked with the at least one isolation capacitor and the bottom switches are linked to the ground.
