Abstract
A support system for at least one of ophthalmic and optometric instruments. A first instrument supporting member is pivotable between a first storage position and a first use position. A second instrument supporting member is moveable between a second storage position and a second use position. The patient can be sequentially examined, in any order, by the first and second instruments while remaining in a test position.
Claims27
A support system for at least one of ophthalmic and optometric measuring instruments adapted to measure vision parameters of a patient in a test position defining a patient space, the support system comprising:
- a support assembly forming at least part of a table top;
- a first instrument supporting member which provides a generally planar instrument support surface and is pivotably mounted on the support assembly about a generally vertical axis, the first instrument supporting member being pivotable between a first storage position and a first use position, wherein the first instrument supporting member is adapted to support a first instrument in the first use position in a defined measuring position;
- and
- a second instrument supporting member moveably mounted on the support assembly for pivotal motion in a generally vertical plane about at least one point proximate to the table top, the second instrument supporting member being movable between a second storage position and a second use position, wherein the second instrument supporting member is adapted to support a second instrument in the second use position in the defined measuring position, wherein the patient can be sequentially examined, in any order, by the first and second instruments while remaining in the test position.
A support system for at least one of ophthalmic and optometric measuring instruments adapted to measure vision parameters of a patient in a test position defining a patient space, the support system comprising:
- a support assembly;
- a first instrument supporting member pivotably mounted on the support assembly about a generally vertical axis, the first instrument supporting member being pivotable between a first storage position and a first use position, wherein the first instrument supporting member is adapted to support a first instrument in the first use position in a defined measuring position;
- a second instrument supporting member moveably on the support assembly for motion in a generally vertical plane, the second instrument supporting member being movable between a second storage position and a second use position, wherein the second instrument supporting member is adapted to support a second instrument in the second use position in the defined measuring position, wherein the patient can be sequentially examined, in any order, by the first and second instruments while remaining in the test position;
- at least two parallel bars each having a first end mounted for pivoting movement relative to the support assembly and each having a second end pivotally attached to an instrument supporting member;
- and
- an actuator connecting the at least two parallel bars and adapted to move the at least two parallel bars between first and second positions to move the second instrument supporting member between the second storage position and the second use position.
A method of examining a patient's eyes, comprising:
- positioning the patient in a test position defining a patient space positioned proximate to a table top;
- moving a first instrument from a first storage position to a first use position in alignment with a position of the patient's eyes, the first instrument being supported by a first instrument supporting member that provides a generally planar support surface and pivots along the table top about a vertical axis;
- moving a second instrument from a second storage position to a second use position in alignment with the same position of the patient's eyes, the second instrument being supported by a second instrument supporting member that has at least one pivot point located proximate to the table top, wherein the patient can be sequentially examined, in any order, by the first and second instruments while remaining in the test position.
A method of evaluating a patient's vision, comprising:
- positioning an evaluator in a seated location at a patient examination station including a table top;
- moving a first instrument from a first storage position to a first use position in alignment with a patient eye position, the first instrument being guided during movement by a first instrument supporting member that provides a generally planar support surface and pivots along the table top about a vertical axis;
- moving a second instrument from a second storage position to a second use position in alignment with the same patient eye position, the second instrument being guided during movement by a second instrument supporting member that has at least one pivot point located proximate to the table top, wherein the patient can be sequentially examined, in any order, by the first and second instruments while the evaluator remains in the seated position.
