Abstract
Description
- 1. Field of the Invention
- The present invention relates to an ophthalmic examination apparatus, and more particularly to an ophthalmic examination apparatus having ophthalmic diagnostic equipment devices that can be used as a portable or fixed system.
- 2. Description of the Prior Art
- Ophthalmic diagnostic equipment devices known in the prior art include the fundus camera, used for diagnostic examination of the eye fundus; the slit lamp, used for diagnostic examination of the anterior portion of the eye; and the tonometer, used for measuring ocular pressure. These apparatuses are divided into fixed types used in a set location, and portable types in which part of the fixed type are omitted to enable the apparatus to be carried by hand.
- There are also ophthalmic apparatuses that can be used as both fixed types and as portable types. Such types, as disclosed by Japanese Patent Laid-open Gazette Nos. 131317/97 and 234184/97, are configured as a portable type ophthalmic diagnostic system that can be detachably fitted to a fixed type system.
- However, while the portable part of the system functions as a portable diagnostic system, some of the functions remain in the main fixed part of the system, so there is a high degree of linkability between the portable and fixed portions. This means that portable type ophthalmic diagnostic equipment devices having another function cannot be fitted to the fixed type. Moreover, functionally connecting the portable and fixed types requires an electrical as well as a mechanical coupling, increasing the complexity of the connection configuration.
- An object of the invention is, therefore, to provide an ophthalmic examination apparatus that is structurally simple and can be readily used as a portable type or as a fixed type system.
- The present invention provides an ophthalmic examination apparatus comprising, a plurality of portable ophthalmic diagnostic equipment devices having different ophthalmic diagnostic functions, means for supporting each ophthalmic diagnostic equipment device in a way that allows each device to be freely exchanged, and means for spatially moving the supporting means.
- The present invention also provides an ophthalmic examination apparatus comprising, portable ophthalmic diagnostic equipment devices, means for supporting each ophthalmic diagnostic equipment device in a way that allows each device to be detachably mounted and, when a device is thus supported, effects only a mechanical coupling with the device, and means for spatially moving the supporting means.
- The present invention also provides an ophthalmic examination apparatus comprising, a plurality of portable ophthalmic diagnostic equipment devices having different ophthalmic diagnostic functions, means for supporting each ophthalmic diagnostic equipment device in a way that allows each device to be freely exchanged and that, when a device is thus supported, effects only a mechanical coupling with the device, and means for spatially moving the supporting means.
- FIG. 1 is a perspective view showing the arrangement of one embodiment of an ophthalmic examination apparatus according to the present invention;
- FIG. 2 is a perspective view showing the arrangement of another embodiment of an ophthalmic examination apparatus according to the present invention;
- FIG. 3 is an illustrative view showing the optical system of a slit lamp; and
- FIG. 4 is an optical view showing the optical system of a fundus camera.
- The invention will now be described with reference to the drawings.
- FIGS. 1 and 2 show embodiments of an ophthalmic examination apparatus according to the invention. In the drawings,
reference numeral 1 denotes a base of the ophthalmic examination apparatus, on which arefixed support uprights uprights chin rest 4 on which the patient being examined rests his chin, and aheadrest 5 against which the patient rests his forehead. Thechin rest 4 can be moved vertically to match the position of each patient's chin. - A
plate 6 is mounted onto thebase 1. Theplate 6 is arranged so that when alever 8 is operated, theplate 6 is moved in a horizontal plane in directions X and Y relative to thebase 1, and when aring 9 is turned, theplate 6 is moved vertically (direction Z). Ablock 7 is affixed to theplate 6. Theblock 7 supports asupport base 10 in such a way that the latter can rotate about the perpendicular axis. The rotation of thesupport base 10 is limited by a stop-screw 7 a provided on theblock 7. - A U-shaped
fixing channel 10 a is formed in thesupport base 10. Thefixing channel 10 a can be used to attach portable ophthalmic diagnostic equipment devices having various functions. - The
slit lamp 20 shown in FIG. 1 is an example of a portable ophthalmic diagnostic equipment device. Theslit lamp 20 has aninsertion base 21 that can be inserted into thefixing channel 10 a. Theinsertion base 21 has apressure member 21 a that is urged outwards by a spring. When thebase 21 is inserted into thefixing channel 10 a, thepressure member 21 a is pressed inwards, allowing theslit lamp 20 to be inserted into thesupport base 10. When theslit lamp 20 is fully inserted, the outward spring pressure of thepressure member 21 a keeps theslit lamp 20 securely attached to thesupport base 10. Theslit lamp 20 can be removed by drawing the lamp back out, which pushes thepressure member 21 a inwards, thereby enabling theslit lamp 20 to be fully removed. - A
slit projection section 22 is rotatably mounted on theinsertion base 21, withaxis 21 b as the axis of rotation. Theslit lamp 20 also has agrip 24. The examiner uses thegrip 24 to project the slit image onto the anterior portion of the patient's eye, via aprojection window 22 a, and, viaeyepiece 23, observes the slit image coming from the eye. - FIG. 3 shows the optical system of the
slit lamp 20. A beam of light from alamp 31 is converted to a parallel beam bylens 32 and then passes via aslit 33 and amirror 34 to be projected onto the anterior portion of the patient's eye E. The image of the anterior portion of the eye projected by the slit light passes viaimaging lens 35 andeyepiece lens 36 for observation by the examiner S. - The
slit lamp 20 itself functions as a portable type ophthalmic diagnostic device. When used for diagnostic purposes, the examiner grasps thegrip 24 and switches onlamp 31 to project the slit light onto the anterior portion of the eye. Diagnosis is performed by observing the image of the reflected light through theeyepiece 23. The portability of theslit lamp 20 makes it suitable for diagnostic examinations of bedridden patients such as elderly persons as well as infants and the like. However, its very portability can be a drawback, in that it cannot be held completely still during examinations. - Therefore, when the examiner wishes to conduct a more stable, reliable examination, he inserts the
insertion base 21 of theslit lamp 20 into thefixing channel 10 a of thesupport base 10 to thereby mechanically couple theslit lamp 20 to thesupport base 10. - The examiner can conduct an eye examination for the patient sitting with his chin against the
chin rest 4 in the same way as when theslit lamp 20 is being used as a portable system. The examiner uses thelever 8 andring 9 to move theplate 6 horizontally and vertically to adjust the position of the slit image, and rotates theslit projection section 22 or supportbase 10 to adjust the direction in which the slit image is projected. - Thus, since the
slit lamp 20 can detachably mounted on thesupport base 10 affixed to theplate 6, it can be used as a portable type device and as a fixed type. Since the slit lamp is only coupled to thesupport base 10 mechanically when used as a fixed type, it enables the arrangement of the fixed part to be simplified. - Other ophthalmic devices can also be used as fixed types simply by considering a mechanical coupling, i.e. by ensuring that the shape of the insertion base matches the fixing channel. FIG. 2 shows an example of this, in the form of a
fundus camera 40. Thecamera 40 illuminates the fundus of a patient's eye and captures images of the fundus. For this, the examiner holds thebody 41 of the camera and uses aswitch 43 to project light through aprojection window 42 to illuminate the fundus. Fundus images can be observed via aneyepiece 44, or captured using animaging section 45 constituted by a photographic camera or CCD camera or the like. - FIG. 4 shows the optical system of the
fundus camera 40. Illuminating light from an illumination light source and illumination optical system (not shown) is projected onto the fundus of the eye E via aprism 51. Light reflected by the fundus passes throughobjective lenses 52 and focusinglens 53 and falls incident on areturn mirror 54. The light reflected by thereturn mirror 54 is then reflected by amirror 55, and is directed to the examiner S via afield lens 56 and aneyepiece lens 58. With thereturn mirror 54 removed from the optical path, a flash lamp (not shown) positioned in the vicinity of the illumination light source is turned on to record images on film or anothersuch recording medium 57. - Thus, the
fundus camera 40 itself functions as a portable type ophthalmic diagnostic device, and can be used to examine the eyes of disabled patients and the like. When there is a risk that hand movement will make conditions too unstable for an examination, or when it is desired to use the camera as a fixed type system, the camera can be mounted on to thesupport base 10 of theplate 6 by using anadapter 50 equipped with aninsertion base 46 for insertion into the fixingchannel 10 a. - The
insertion base 46 also has a spring-loadedpressure member 46 a that enables theinsertion base 46 to be detachably mounted on thesupport base 10. Also affixed to theinsertion base 46, via asupport 47, is a fixingframe 48. To use, the examiner opens acover 49, fits thecamera 40 to the fixingframe 48, and then clamps the camera in place on theadaptor 50 by latching thecover hook 49 a onto the lockpiece 48 a. The camera is then fitted onto the fixed part of the system by sliding theinsertion base 46 into thesupport base 10. - In this way, the examiner can use the
camera 40 to examine and/or capture images of the eye in the same way as when the camera is being used as a portable system. The examiner uses thelever 8 andring 9 to move theplate 6 horizontally and vertically to align the camera with the eye, and rotates thesupport base 10 to adjust the direction in which the fundus image is viewed or captured. - While this embodiment uses an
adaptor 50 to fit thefundus camera 40 onto theplate 6, the camera may instead be provided with an insertion base to enable the camera to be mounted without using an adaptor. - Similarly, the electrical feed for the illumination lamp and illumination light source of the
slit lamp 20 andcamera 40, and the requisite power supply, can be incorporated internally or provided externally via a power cord. Even if power is provided externally, there is no need to provide an electrical connection between a device to be mounted and the fixed part of the system for receiving the device because the power does not have to be supplied via the fixed part of the system. This simplifies the system arrangement and reduces the cost. - While the aspects of the invention have been described using a slit lamp and fundus camera as examples, the invention also applies to other ophthalmic diagnostic devices, such as an ocular tonometer or other such device configured as a portable system, which can be used as a fixed system using the
support base 10 on theplate 6 as shown in FIGS. 1 and 2. - As described in the foregoing, the present invention provides a simplified ophthalmic examination apparatus in which various ophthalmic diagnostic devices can be used as portable and as fixed system devices. As such, the invention can be used to build ophthalmic examination systems for a wide range of ophthalmic diagnostic applications. Moreover, when a portable device is used as a fixed system, it is only mechanically linked to the fixed part. This simplifies the arrangement of the fixed portion and also allows various ophthalmic diagnostic devices to be fitted to the fixed part.
