Portable continuously self-monitoring bone healing device and method

Claim 2

A completely portable, continuously self-monitoring device for expediting the healing of bone or soft tissue fractures or defects in a patient, said device comprising: an electrical power supply, a plurality of first electrodes, a second electrode and circuit means cooperating with said power supply for applying a regulated flow of current between each of said first electrodes and said second electrode through the fracture or defect site in the patient by the appropriate placement of said electrodes relative to said site; and monitoring means cooperating with said power supply, all of said electrodes and said circuit means during operation of the device for continuously detecting and visually indicating whether or not said power supply is in operating order and whether or not a minimum predetermined amount of current is flowing between each of said first electrodes and said second electrode, said monitoring means including means for visually indicating whether or not said power supply is in operating order and whether or not current is flowing between each of said first electrodes and said second electrode, said visual indicating means including fixed indicia representing that the power supply is on and representing the circuit paths between corresponding first electrodes and the second electrode so long as the power supply is in operating order and, if said power supply is in operating order, changeable indicia adjacent the fixed indicia for indicating whether or not at least said predetermined amount of current is flowing between each of said first electrodes and said second electrode.

Claim 3

A device according to claim 1 including housing means for containing said power supply, said circuit means and said monitoring means, said housing means and the components contained thereby being sufficiently small and lightweight to be easily carried by said patient.

Claim 4

A device according to claim 2 wherein said housing means includes a viewing window and wherein said visual indicating means includes a visual display readily observable by the patient through said viewing window.

Claim 5

A device according to claim 1 including means for securing said power supply, circuit means and monitoring means to said patient whereby during operation of the device the latter can be carried around by the patient.

Claim 6

A completely portable, continuously self-monitoring device for expediting the healing of bone or soft tissue fractures or defects in a patient, said device comprising: an electrical power supply; a plurality of first electrodes adapted for placement at predetermined positions within said patient at the fracture or defect site; a second electrode adapted for placement at a predetermined position against the outer skin of the patient in close proximity to the fracture or defect site; electronic circuitry means interconnecting said electrodes with said power supply so as to cause a regulated supply of current to flow between each of said first electrodes and said second electrode through said fracture or defect site when said electrodes are placed in said predetermined positions; monitoring means cooperating with said power supply, electronic circuitry means and electrodes during operation of the device for continuously detecting and visually indicating whether or not said power supply is in operating order and whether or not a minimum predetermined amount of current is flowing between each of said first electrodes and said second electrodes, said monitoring means including indicia for visually indicating whether or not said power supply is in proper operating order and whether or not said minimum predetermined amount of current is flowing between each of said first electrodes and said second electrode, said indicia including the words BATTERY ON and the numerals 1, 2, 3 and 4 corresponding to circuit paths between four first electrodes and said second electrode so long as the power supply is in operating order and the indication OK by each numeral so long as said medium predetermined amount of current flows through the path corresponding to that number; and housing means for containing said power supply, said electronic circuitry means and said monitoring means, said housing means and the components contained thereby being sufficiently small and lightweight to be easily carried by said patient and said housing means including a viewing window through which the patient can observe the indicia forming part of said monitoring means.

Claim 7

A completely portable, continuously self-monitoring device for expediting the healing of bone or soft tissue fractures or defects in a patient, said device comprising: an electrical power supply; a plurality of first electrodes adapted for placement at predetermined positions within said patient at the fracture or defect site; a second electrode adapted for placement at a predetermined position against the outer skin of the patient in close proximity to the fracture or defect site; electronic circuitry means interconnecting said electrodes with said power supply so as to cause a regulated supply of current to flow between each of said first electrodes and said second electrode through said fracture or defect site when said electrodes are placed in said predetermined positions; monitoring means cooperating with said power supply, electronic circuitry means and electrodes during operation of the device for continuously detecting and visually indicating whether or not said power supply is in operating order and whether or not a minimum predetermined amount of current is flowing between each of said first electrodes and said second electrodes, said monitoring means including indicia for visually indicating whether or not said power supply is in proper operating order and whether or not said minimum predetermined amount of current is flowing between each of said first electrodes and said second electrode, said indicia including the words BATTERY ON and the numerals 1, 2, 3 and 4 corresponding to circuit paths between four first electrodes and said second electrode so long as the power supply is in operating order and the indication OK by each numeral so long as said medium predetermined amount of current flows through the path corresponding to that number; and housing means for containing said power supply, said electronic circuitry means and said monitoring means, said housing means and the components contained thereby being sufficiently small and lightweight to be easily carried by said patient and said housing means including a viewing window through which the patient can observe the indicia forming part of said monitoring means.
