Fixing device of multifunctional ophthalmologic examination apparatus

Abstract

The invention discloses a fixing device of a multifunctional ophthalmologic examination apparatus. The fixing device comprises a base plate, wherein a first electric telescopic rod is arranged on the surface of the base plate; a mounting plate is arranged at the top end of the first electric telescopic rod; a lower connecting plate is connected to the top end of the mounting plate by virtue of a second electric telescopic rod; an upper connecting plate is connected to the lower connecting plate by virtue of a third electric telescopic rod; a lower retaining ring is arranged on the surface of the lower connecting plate; in correspondence to the lower retaining ring, an upper retaining ring is arranged at the bottom end of the upper connecting plate; a first storage box is arranged on the surface of the base plate at one side of the mounting plate; and a second storage box is arranged on the surface of the base plate at the other side of the mounting plate. According to the fixing device of the multifunctional ophthalmologic examination apparatus, the head of an examined object can be firmly fixed by virtue of the upper retaining ring and the lower retaining ring; ad by adjusting telescopic amounts of the various electric telescopic rods, the examination equipment can be kept at a height which is relatively suitable for measurement of the examined object, so that a user is facilitated in using.

Description

technical field [0001] The invention relates to the technical field of fixing devices for inspection instruments, in particular to a fixing device for multifunctional ophthalmic inspection instruments. Background technique [0002] As a basis for diagnosis, inspection equipment provides a basis for ophthalmologists to formulate diagnosis and treatment plans. However, present various ophthalmic examination instruments usually include ophthalmoscope, slit lamp microscope, retinoscopy mirror, optometry box, eye chart box, tonometer, ophthalmic A-ultrasound, fundus camera, etc. Usually, the patient's chin is placed on a base that supports the chin, and then the inspection is performed. During the inspection, due to the structure of the human body, the head of the person will inevitably move, but the accuracy of general inspection instruments is relatively high, and the head moves It will inevitably affect the accuracy of the detection data, and the current fixing device cannot ...

However, present various ophthalmic examination instruments usually include ophthalmoscope, slit lamp microscope, retinoscopy mirror, optometry box, eye chart box, tonometer, ophthalmic A-ultrasound, fundus camera, etc. Usually, the patient's chin is placed on a base that supports the chin, and then the inspection is performed. During the inspection, due to the structure of the human body, the head of the person will inevitably move, but the accuracy of general inspection instruments is relatively high, and the head moves It will inevitably affect the accuracy of the detection data, and the current fixing device cannot adjust the height of the equipment, so it is not convenient to detect people of different heights
