ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an ophthalmic apparatus for performing observations, measurements, and laser treatments with respect to a patient's eye, the apparatus being provided with a head support unit for supporting the head of the patient to hold the patient's eye in position.
2. Description of Related Art
In some instances, ophthalmic apparatus for performing observations, measurements, and laser treatments with respect to a patient's eye are transported from a location to another as required. For example, when a single ophthalmic laser treatment apparatus used for treating an affected part of a patient's eye by irradiating the eye with a treatment laser beam is shared among plural hospitals or clinics, this laser treatment apparatus is needed transporting from one of the hospitals or clinics to another. For enabling transportation, the apparatus is housed in a transportation case which protects the apparatus and provides ease of transportation thereof.
The ophthalmic laser treatment apparatus generally includes a slit lamp used for observation of a patient's eye and a main unit including a laser irradiation optical system. Those slit lamp and main unit are movably mounted on a base board. On this base board, also fixed is a head support unit for fixedly supporting the head of a patient. In association therewith, a transportation case for packing the apparatus as an integral unit is needed increasing in size. This causes deterioration in transportability of the case packing the apparatus therein. Also, if the case is large in weight, even the transportation thereof would not be easy.
SUMMARY OF THE INVENTION
The present invention has been made in view of the above circumstances and has an object to overcome the above problems and to provide an ophthalmic apparatus capable of being packed in a transportation case of a smaller size as compared with a conventional case for ophthalmic apparatus of an integral unit type, thereby providing improved transportability.
Additional objects and advantages of the invention will be set forth in part in the description which follows and in part will be obvious from the description, or may be learned by practice of the invention. The objects and advantages of the invention may be realized and attained by means of the instrumentalities and combinations particularly pointed out in the appended claims.
To achieve the purpose of the invention, there is provided an ophthalmic apparatus including: a base board; a main unit detachably mounted on the base board; and a head support unit fixed on the base board, the unit being at least foldable to or detachable from the base board.
According to the present invention, the apparatus can be packed or housed in a compact form in a smaller transportation case as compared with a conventional case. This can improve transportability of the apparatus.
According to another aspect of the present invention, there is provided an ophthalmic apparatus including: a base board; a main unit; a head support unit fixed on the base board; means for enabling mounting and dismounting of the main unit with respect to the base board; and means for changing a fixing state of the head support unit with respect to the base board.
