Abstract
A device forming a combination ophthalmoscope and otoscope, having a housing (4) supporting a light source (10) and a plurality of lenses (8, 9), the light source (10) defining an illumination light path (14) which illuminates in use a region of interest (15), the housing having an aperture (12) defining a viewing light path (13) along which the region of interest (15) can be viewed, the lenses (8, 9) being mounted on a support (1) relative to the housing (4) so as to be moveable relative to the housing (1) so as to allow selection of a lens from the plurality of lenses (8, 9) to be disposed in the viewing light path, and in which the plurality of lenses form an ophthalmoscopy set (8) comprising at least one ophthalmoscopy lens and an otoscopy set (9) comprising at least one otoscopy lens.
Claims19
A device forming a combination ophthalmoscope and otoscope, having a housing supporting a light source and a plurality of lenses, the light source defining an illumination light path which illuminates in use a region of interest, the housing having an aperture defining a viewing light path along which the region of interest can be viewed, the lenses being mounted on a support relative to the housing so as to be moveable relative to the housing so as to allow selection of a lens from the plurality of lenses to be disposed in the viewing light path, and in which the plurality of lenses form an ophthalmoscopy set comprising at least one ophthalmoscopy lens and an otoscopy set comprising at least one otoscopy lens, further comprising a viewing shutter, which selectively blocks the viewing light path so as to allow the field of view of the device to be controlled.
A method of carrying out ophthalmoscopy and otoscopy, comprising:
- providing a device forming a combination ophthalmoscope and otoscope, having a housing supporting a light source and a plurality of lenses, the light source defining an illumination light path which illuminates in use a region of interest, the housing having an aperture defining a viewing light path along which the region of interest can be viewed, the lenses being mounted on a support relative to the housing so as to be moveable relative to the housing so as to allow selection of a lens from the plurality of lenses to be disposed in the viewing light path, and in which the plurality of lenses form an ophthalmoscopy set comprising at least one ophthalmoscopy lens and an otoscopy set comprising at least one otoscopy lens, further comprising a viewing shutter, which selectively blocks the viewing light path so as to allow the field of view of the device to be controlled;
- and
- using the device to view a region of interest in a patient's eye and a region of interest in a patient's ear canal.
A device forming a combination ophthalmoscope and otoscope, having a housing supporting a light source and a plurality of lenses, the light source defining an illumination light path which illuminates in use a region of interest, the housing having an aperture defining a viewing light path along which the region of interest can be viewed, the lenses being mounted on a support relative to the housing so as to be moveable relative to the housing so as to allow selection of a lens from the plurality of lenses to be disposed in the viewing light path, and in which the plurality of lenses form an ophthalmoscopy set comprising at least one ophthalmoscopy lens and an otoscopy set comprising at least one otoscopy lens, in which the lenses are mounted relative to the housing by the support such that a first selection of whether a lens of the ophthalmoscopy or otoscopy sets is in the viewing light path is made by displacing the support radially, whereas the a second selection of which lens within a set is in the viewing light path is made by rotating the support about its axis.
