Abstract

The apparatus is used for therapeutically treating injuries using ultrasound. The apparatus includes an ergonomically constructed ultrasonic transducer treatment head module partially fabricated with a conductive plastic material. The apparatus also utilizes a portable, ergonomically constructed main operating unit constructed to fit within a pouch worn by the patient. In operation, the transducer treatment head module is positioned adjacent the area of the injury and excited for a predetermined period of time. To ensure that the transducer treatment head module is properly positioned, and to insure compliance with a treatment protocol, a safety interlock is provided to prevent inadvertent excitation of the transducer.

Claims

1. An apparatus for ultrasonically treating an injury comprising:

a portable self-contained main operating unit having an internal power source and dimensioned to be carried by a patient during treatment, a support fixture configured and adapted for attachment adjacent an external site corresponding to an internal injury remote from said main operating unit, and an ultrasonic transducer treatment head module operatively connected to said main operating unit and including means for detachably engaging said support fixture, said treatment head module having an ultrasonic signal generator and signal generator circuitry operatively associated therewith, said main operating unit having a display panel coupled to said signal generator circuitry to display treatment sequence data and a keypad coupled to said signal generator circuitry to permit user control, of said signal generator, said signal generator circuitry including a processor, means for generating a pulsed signal, and a switch coupled to said processor for regulating said pulsed signal.

2. The apparatus according to claim 1 further comprising a pouch, wherein said main operating unit is positioned within said pouch and worn by the patient to permit portable operation thereof.

3. The apparatus according to claim 1 further comprising an optical transmitter connected to said switch, said optical transmitter being configured to convert said pulsed signal to an optical signal.

4. The apparatus according to claim 1 further comprising a communication interface connected between a communication port and said processor to provide a communication link between said ultrasonic signal generator and an external computer/modem.

5. The apparatus according to claim 4, wherein said communication interface is a serial communication interface.

6. The apparatus according to claim 1 further comprising an alarm connected to said processor to indicate accurate compliance with a treatment protocol.

7. The apparatus according to claim 1, wherein said fixture has an aperture configured to receive a portion of said ultrasonic transducer treatment head module and at least two bayonet lugs extending into said aperture which are electrically connected to form a conductive path therebetween.

8. The apparatus according to claim 7, wherein said ultrasonic transducer treatment head module includes at least two slotted lugs having at least a portion thereof extending from an outer surface of said module and configured to engage said at least two bayonet lugs, said at least two slotted lugs being fabricated from conductive plastic such that when said slotted lugs engage said bayonet lugs a conductive path is formed between said slotted lugs.

9. A kit for ultrasonically treating injuries while maintaining patient mobility, which comprises:

a support fixture configured and adapted to be worn by a patient adjacent an external site of an internal injury;

an ultrasonic transducer treatment head module including an ultrasonic signal generator and means for detachably engaging said support fixture;

a portable self-contained main operating unit operatively connected to said treatment head module and including means for facilitating user control of said signal generator; and

a pouch dimensioned and configured to receive and maintain said main operating unit in a location remote from said support fixture, said pouch including a support belt adapted to be worn by a patient during treatment to afford mobility.

10. The kit according to claim 9, wherein said fixture includes an aperture configured to receive a portion of said ultrasonic transducer treatment head module and at least two bayonet lugs extending into said aperture, which are electrically connected to form a conductive path therebetween.

11. The kit according to claim 10, wherein said ultrasonic transducer treatment head module includes at least two slotted lugs having at least a portion thereof extending from an outer surface of said transducer treatment head module and configured to engage said at least two bayonet lugs, said at least two slotted lugs being fabricated from conductive plastic such that when said slotted lugs engage said bayonet lugs a conductive path is formed between said slotted lugs.

12. The kit according to claim 9, wherein said ultrasonic signal generator includes signal generator circuitry and an internal power source connected to said signal generator circuitry, a display coupled to said signal generator circuitry to display treatment sequence data, a keypad coupled to said signal generator circuitry to permit user control and/or entry of data, said signal generator circuitry including a processor, means for generating a pulsed RF signal, and a switch coupled to said processor for regulating said pulsed RF signal.

13. The kit according to claim 12 further comprising a communication interface connected between a communication port and said processor to provide a communication link between said ultrasonic signal generator and an external computer.

14. The kit according to claim 9 further comprising a cap, engagable with said fixture to replace said ultrasonic transducer treatment head module when the module is not being used for treatment.

15. The kit according to claim 14 further comprising a pad, configured and adapted to be positioned between said cap and a skin surface of said patient for applying a predetermined pressure to said skin surface.

16. The kit according to claim 9 further comprising a shoulder harness attached to said belt to provide additional support for the pouch.
