Abstract

An apparatus for medical inspection comprising a hand-held medical diagnostic instrument having a battery pack for providing energy to a light source for illuminating the target area, a housing, a charger for charger the battery pack that is integral with the housing and adapted to provide electric energy to the battery pack to charge the battery pack, a video adapter detachably coupled to the medical diagnostic instrument, video processing circuitry contained within the housing and an umbilicus for connecting the video adapter to the video processing circuitry.

Claims

1. An integrated video inspection apparatus, said apparatus comprising:

a housing including means for supporting at least one hand-held optical diagnostic instrument, said at least one hand-held optical instrument having a contained light source for illuminating a target area and a battery pack for providing energy to the light source;

at least one video imaging adapter detachably engageable with said at least one diagnostic instrument, said at least one video imaging adapter including a miniature video camera and means for coupling said adapter to said instrument for allowing said at least one optical instrument to be converted into a videoized diagnostic instrument;

video processing circuitry associated with said at least one video imaging adapter disposed within said housing;

means for connecting said at least one video imaging adapter to said video processing circuitry, said video processing circuitry including means for calibrating the contained miniature video camera; and

means disposed in said housing for storing calibration data obtained by said calibration means.

2. Apparatus as recited in claim 1, including means integral to said housing for recharging said battery pack of said at least one instrument.

3. Apparatus as recited in claim 1, wherein said housing includes means for retaining at least two hand-held optical diagnostic instruments and at least two video imaging adapters, each adapter being detachably engageable with one of said instruments, said apparatus further including switching means for selectively operating any of said instruments wherein operation of said switching means automatically utilizes calibration data stored by said storage means relating to the instrument selected.

4. Apparatus as recited in claim 1, including a video monitor integral to said housing.

5. An integrated video inspection apparatus, said apparatus comprising:

at least two hand-held optical diagnostic instruments, each of said instruments having a light source for illuminating a target area;

a housing;

at least two video imaging adapters, each said adapter being detachably engageable with said at least two optical diagnostic instruments and including a miniature video camera and means for coupling to at least one of said optical diagnostic instruments;

video processing circuitry associated with said housing;

means for connecting said video imaging adapters to said video processing circuitry; and

switching means for selectively relaying from any one of said at least two video imaging adapters to said video processing circuitry.

6. Apparatus as recited in claim 5, wherein said housing includes an integral video monitor connected to said switching means for displaying video images captured by any connected instrument.

7. Apparatus as recited in claim 5, including calibration means for calibrating the miniature video camera of said at least two video imaging adapters when engaged with a corresponding optical instrument and storing means for storing calibration data of each instrument calibrated by said calibration means.

8. Apparatus as recited in claim 7, in which said switching means is connected to said storing means to automatically recall calibration data relating to a particular instrument without requiring recalibration when any said instrument is selected.

9. A method of selectively and interchangeably using at least two videoized diagnostic instruments, each of said instruments being supported by a housing having video processing circuitry contained therein, said method comprising the steps of:

selecting a first videoized instrument;

calibrating said first instrument for white balance;

storing calibration data relating to white balance associated with said first instrument in storing means associated with said housing;

selecting a second videoized instrument;

calibrating said second instrument for white balancing said selected instrument;

storing calibration data associated with said second instrument in said storage means; and

selecting one of said instruments at a later time using switching means provided on said housing, wherein said selecting step automatically utilizes the stored calibration data associated with the selected instrument without need for recalibrating said instrument.
