  • Patent number: 4561851
    Abstract: An apparatus for demonstrating and teaching the application of transcutaneous electrical nerve stimulation to a human or animal body includes a representation of such body with receptors thereon at different sites thereof corresponding to treatment sites of different pains which could afflict the body, electronic circuits capable of visually indicating locations of pain when switched on, and electronic circuits for visually showing paths of transcutaneous electrical nerve stimulation on the body representation when a transcutaneous electrical nerve stimulator is connected to the receptors and is activated. When the correct receptors are connected to T.E.N.S. unit for the treatment of a particular visually indicated pain and the T.E.N.S. unit is turned on the indication of the pain is cancelled. Also disclosed are apparatuses with which the electrical stimulator employed is of a type other than a T.E.N.S. unit, such as bone growth and muscle stimulators.

  • Patent number: 4141367
    Abstract: An instrument for detecting and measuring various characteristics of cardiac pacers and electrodes and visually displaying such measurements selectively on a digital display includes pacer analyzer means for measuring and displaying characteristics of a pacer, such as rate, pulse width, peak voltage and trailing edge voltage, electrode analyzing means for measuring and displaying characteristics of an installed electrode, such as impedance and intrinsic and evoked R-wave voltages and internal pacer means including means for adjusting pacer impulse rate and voltage and means for measuring and displaying various pacer characteristics of the internal pacer impulses, such as rate, voltage and amperage, a rechargeable battery for energizing the various circuits of the instrument and means for preventing externally supplied battery recharging electric power from communicating through the instrument with installed cardiac electrodes and with a pacer to be tested.
