APPARATUS FOR ELECTRICAL PULSE STIMULATION

摘要

A method and structure of artificially inducing the return of arrested body functions caused by paralytic ileus and pain associated therewith after surgery or accidental trauma on the human body. The equipment is in the form of electronic circuits producing a generally rectangular or square wave shape which is variable from 10 to 300 pulses per second having a pulse width of 50 to 1000 microseconds. The circuit includes a pair of constant current amplifiers capable of supplying two different output signals having a pulse amplitude of 80 milli-amperes maximum current to provide a current density range of 1 to 50 x 10-6 amperes per square millimeter depending on the electrode area or size. Electrodes are connected to current generators and placed on the body in the area of the lower abdomen in accidental trauma or close to the area of incision post operatively. Posterior electrodes may also be placed on the body as well as over the nerves and particularly the intercostal nerves leading to the site of the incision to further aid in restoring body functions.
