OBJECT OF THE INVENTION It is an object of the invention to provide apparatus which is not only effective in the treatment of the above disorders but which is reliable and easy to use.
DISCLOSURE OF THE INVENTION According to the invention apparatus is provided which comprises a negatively charged body electrode and a positively charged floating electrode, a source of current of suitable voltage connected to a variable electrical control system which in turn is connected to an internal operating battery to provide direct current to the electrodes. A suitable mains powered battery charger is provided as a separate unit for connection to the system via a DC plug and panel mounted socket for recharging the internal battery, control system and, when necessary, a'stand-by'battery connectable to an additional panel mounted socket.
This'stand-by'battery is provided for situations where the internal battery becomes depleted or malfunctions, when remote from a mains power supply for the charger, such as when treating animals in a stable. On plugging in the'stand-by'battery, the depleted internal battery is automatically disconnected from the control and charging circuitry.
The batteries and charger are included in an electrical circuit's having variable resistors, condensers and the like to vary the voltage, the pulse rate of the voltage and other parameters to vary the period between stimuli. A pulse rate of from 0.5 to 1.5 seconds is the normal rate but this may be varied for special circumstances and treatments.
The direct current is preferably 12 volts which can be varied by a suitable rheostat.
A charging current of 200 milliamps has been found to be convenient and efficient.
One of the main advantages of the invention is that the electrodes are not directly or indirectly connected to mains current, which may otherwise cause damage to the internal circuitry, and/or electrodes which have to be wetted with a salt solution for conductivity, or, most importantly, possibly present a risk to the patient under treatment.
The invention may be used for a great variety of purposes, using Faradic principles for the treatment of tendons, muscles, joints, sprains, dislocations, sinusitis, osteo-arthritis, nerve injuries, haematoma, fibrositis among many others. The use of the apparatus causes an increase of blood to be brought to the affected zone with resulting beneficial physiological consequences.
BRIEF DESCRIPTION OF THE DRA WING An embodiment of the invention is illustrated in the accompanying electronic wiring diagram.
