Functional Electrical Stimulation Synchronizer Switch
US Patent:
4809696, Mar 7, 1989
Filed:
Sep 21, 1987
Appl. No.:
7/099092
Inventors:
Charles J. Laenger - Tulsa OK
Henry L. Hughes - Tulsa OK
Thomas C. Burk - Tulsa OK
Henry L. Hughes - Tulsa OK
Thomas C. Burk - Tulsa OK
Assignee:
Hillcrest Medical Center - Tulsa OK
International Classification:
A61N 136
US Classification:
128419R
Abstract:
This is an electrical stimulating device which is used with an exerciser having bicycle-like pedals to aid people with paralyzed legs. Several miniature magnetic reed switches are mounted in a first and a second semi-circular arrays on a switchboard. The switchboard is placed in a plane parallel to the plane on which the pedals rotate. The pedal carries a permanent magnet which rotates in a plane adjacent to the switches and sequentially activates the reed switches. The activation of the reed switches directs the stimulation pulses from a neuromuscular simulator (NMS) to the patient's quadriceps to effect total extension of the leg.
Exerciser With Muscle Stimulation
US Patent:

Assignee:
Hillcrest Medical Center - Tulsa OK
International Classification:
A61N 102, A61N 136
US Classification:
128419R
Abstract:
An exerciser with an electrical stimulating device for exercising persons having paralyzed legs and the like, the exerciser having bicycle-like pedals supported on rotatable arms, and having a switchboard disposed in a plane substantially parallel to the rotational plane of the rotatable arms. Arrays of magnetically actuated switches are supported by the switchboard in semi-circular paths, and a permanent magnet is supported by one of the rotatably arms to sequentially activate the switches which, as part of a circuit containing a neuromuscular stimulator, effects selective electrical stimulation of the persons muscles to effect rotation of the rotatable arms.
