Abstract

There is provided a video monitoring, recording and transmission elements for use in combination with a hand-held medical opto-diagnostic office-use instrument such as an otoscope and an ophthalmoscope. The adaptor, beam splitter and video camera head portions of the system are proportioned in physical size to about the same size as an existing hand-held, office-use, examination instrument of the physician. The components of the system may be selectably coupled and de-coupled with an otherwise conventional otoscope or ophthalmoscope.

Claims

1. A hand-held opto-diagnostic system for use within a conventional physician-patient examining distance not exceeding the manual reach of the doctor, the system comprising:

(a) a hand-held, non-surgical, opto-diagnostic medical instrument, said instrument including a light source, an eyepiece, a direct view optical pathway for light generated by said light source, and a power supply for said light source;

(b) a hand-held mechanical and optical adapter proportioned for selectable coupling to, and de-coupling from, said eyepiece of said instrument without modifications of said optical pathway thereof,

(c) a beam splitter mechanically and optically coupled into said optical pathway to said adapter, said pathway originating from said instrument and extending into said beam splitter, a first optical output of said beam splitter includes said direct view optical pathway of said instrument, said path directed to a system eyepiece located within said conventional physical-patient examining distance thereof, and a second output of said beam splitter includes an optical pathway mechanically and optically coupled to an input to a video camera head coupled to a video camera; and

(d) video monitoring and recording means opto-electronically coupled to an output of said video camera.

2. The system as recited in claim 1 in which said beam splitter and a video head of said video camera are proportioned in physical size to about the physical size of said opto-diagnostic medical instrument.

3. The system as recited in claim 2, further comprising an informational transmission link electronically connected to an output of said video camera.

4. The system as recited in claim 2, further comprising an alternative light source optically coupled to said instrument.

5. The system as recited in claim 2, further comprising a supplemental power source electrically connected to a battery power circuit of said instrument.
