Portable physio-therapy apparatus
First Claim
1. A physio-therapy apparatus for applying electrical stimulation to a human patient, the apparatus comprising a portable housing having first and second portions, said first housing portion containing a memory for storing at least one therapy program defining the characteristics of electrical signals to be applied to the patient, first electrical connector means for connecting external stimulation electrodes to the housing, and a microprocessor for driving the electrodes according to said at least one therapy program, and said second housing portion having a plurality of manual control elements for controlling the microprocessor to modify at least some of the electrical signal characteristics of said at least one therapy program, wherein said second housing portion is detachably connected to said first housing portion by a second electrical connector means whereby said electrical signal characteristics cannot be modified without said second housing portion being attached to said first housing portion.

Abstract
A physio-therapy apparatus for applying electrical stimulation to a human patient comprising a two-part portable housing. The first housing portion contains a memory for storing a plurality of therapy programs each defining the parameters of electrical signals to be applied to the patient according to that program, first electrical connector means for connecting external stimulation electrodes to the housing, and a microprocessor for driving the electrodes according to a selected one of the stored programs. The second housing portion has a plurality of manual control elements in the form of keys for controlling the microprocessor to select a particular stored program and/or to modify electrical signal parameters of at least one stored program. The second housing portion is detachably connected to said first housing portion by a second electrical connector means whereby a selected program cannot be changed and/or said electrical signal parameters cannot be modified without said second housing portion being attached to said first housing portion.
