Abstract
Electrical stimulation through externally applied electrodes is used to control discharge from a stoma. The electrical signals applied to the electrodes have a frequency in the range of 10 Hz to 80 Hz, and a voltage level in the range of 20 volts to 60 volts. Apparatus for effecting the electrical stimulation is described. The electrodes may be ECG electrodes or formed as a pair of discs molded into an insulating pad.
Claims10
A method for controlling discharge from a stoma comprising:
- (a) winding a length of muscle around the intestine connected to the stoma in the region adjacent to the stoma;
- (b) applying a pair of mutually spaced electrodes to the skin in the region of the length of muscle;
- and
- (C) applying to the electrodes a continuous electrical signal at a voltage in the range 20 volts to 60 volts and at a frequency in the range 10 Hz to 80 Hz,
- whereby the length of muscle is caused to contract around the intestine and effectively prevent discharge through the stoma.
