Abstract

An otoscope provides a circular display allowing a compact housing providing improved simultaneous viewing of the display and the patient's ear for improved positioning and stabilization of the otoscope. A recorded image may be rotationally corrected, and non-image data displayed on the screen may be rotationally corrected with the use of an inclinometer.

First claim

What we claim is:

1. An otoscope comprising: a housing adapted for support by a hand of a healthcare professional with the housing in an inspection position adjacent to an outer ear of a patient; an elongate probe element having a proximal end supported by the housing so that a distal end of the elongate probe element extends rigidly from the proximal end to the distal end along a linear axis into an ear canal of the patient; an electronic camera supported at the distal end of the elongate probe element for viewing into the ear canal when the distal end of the probe element is positioned in the ear canal of the outer ear; and a circular electronic display supported by the housing and communicating with the electronic camera and having a display area facing away from the direction of viewing by the electronic camera, and having an outer circular periphery displaying an otoscope image taken by the electronic camera, and spaced from the distal end of the elongate probe along the linear axis and centered along the linear axis to extend outwardly to the circular periphery a substantially same distance at all angles perpendicular to the linear axis; further including an electronic inclinometer for changing at least one of an orientation of non-otoscope image data on the circular electronic display and the otoscope image according to a deduced gravitational vector.

2. The otoscope of claim 1 further including a processor executing a stored program for displaying a non-otoscope image data in a peripheral ring about the otoscope image.

3. The otoscope of claim 1 wherein the circular display presents non-otoscope image data indicating a left ear recorded or right ear recorded indicator.

4. An otoscope comprising: a housing adapted for support by a hand of a healthcare professional with the housing in an inspection position adjacent to an outer ear of a patient; an elongate probe element having a proximal end supported by the housing so that a distal end of the elongate probe element extends rigidly from the proximal end to the distal end along a linear axis into an ear canal of the patient; an electronic camera supported at the distal end of the elongate probe element for viewing into the ear canal when the distal end of the probe element is positioned in the ear canal of the outer ear; and a circular electronic display supported by the housing and communicating with the electronic camera and having a display area facing away from the direction of viewing by the electronic camera, and having an outer circular periphery displaying an otoscope image taken by the electronic camera, and spaced from the distal end of the elongate probe along the linear axis and centered along the linear axis to extend outwardly to the circular periphery a substantially same distance at all angles perpendicular to the linear axis; wherein the housing provides a display portion holding the circular electronic display and elongate probe, and a handle portion extending away from the linear axis to be held by a healthcare professional and wherein the display portion is mechanically and electrically releasably attachable to the handle portion by means of a twist lock coupling; and wherein the handle portion provides an operator controlling electrical power delivered to the display portion and wherein the handle portion provides a collar fitting over the operator to prevent movement of the operator.

5. The otoscope of claim 4 wherein the collar portion includes an engagement surface turning the operator to a full power position with rotation of the twist lock coupling for engagement.

6. An otoscope comprising: a housing adapted for support by a hand of a healthcare professional with the housing in an inspection position adjacent to an outer ear of a patient; an elongate probe element having a proximal end supported by the housing so that a distal end of the elongate probe element extends rigidly from the proximal end to the distal end along a linear axis into an ear canal of the patient; an electronic camera supported at the distal end of the elongate probe element for viewing into the ear canal when the distal end of the probe element is positioned in the ear canal of the outer ear; and a circular electronic display supported by the housing and communicating with the electronic camera and having a display area facing away from the direction of viewing by the electronic camera, and having an outer circular periphery displaying an otoscope image taken by the electronic camera, and spaced from the distal end of the elongate probe along the linear axis and centered along the linear axis to extend outwardly to the circular periphery a substantially same distance at all angles perpendicular to the linear axis; further comprising: a tubular sheath sized to fit within the ear canal and to receive the elongate otoscope probe element therein, wherein the distal end of the tubular sheath is covered by a transparent window and a proximal end providing a connection to the housing; wherein the transparent window covering is an elastic cot and the connection of the tubular sheath to the housing stretches the elastic cot over the electronic camera to provide a transparent covering to the camera allowing imaging therethrough; and wherein the proximal end of the tubular sheath provides a spring biasing of the transparent window against the distal end of the probe element.
