Ophthalmology testboard and tonometer

Abstract

The invention discloses an ophthalmology testboard and a tonometer. The ophthalmology testboard comprises two sets of symmetrically arranged supporting frames, and a head supporting plate arranged between the two sets of supporting frames in a crossing manner. A movable eyelid opening device is further arranged above each set of supporting frame, the head supporting plate is movable, the head supporting plate and the eyelid opening devices are connected through a driving mechanism, and when the head of a to-be-detected ophthalmology patient is placed on the head supporting plate and eyes correspond to the eyelid opening devices and the head presses the head supporting plate downwards and forcibly, the eyelid opening devices are driven to open the eyes of the patient. On one hand, the patient can be forced to open the eyes for detection, on the other hand, the size of the eyes can be opened according to reality, and pressure can be properly exerted on the head supporting table according to feelings.

Description

technical field [0001] The invention belongs to the technical field of hospital ophthalmology, and in particular relates to an ophthalmology test bench and a tonometer. Background technique [0002] A tonometer is an instrument that measures the pressure in the eye of the human eye. It can assist in the diagnosis of cataracts, glaucoma and other eye diseases. Now commonly used is the non-contact tonometer, which has the advantages of easy operation and rapid measurement. Move the chin to the chin rest, and put the eyes on the air pressure mouthpiece of the tonometer body. During the test, the air pressure mouthpiece will blow air pressure into the eyeball, and the device will perform a feedback test on the intraocular pressure to obtain the intraocular pressure data. In actual use, It often occurs that the patient to be tested has poor self-control ability and uncontrollable frequent blinking, resulting in failure of measurement results or large measurement errors, which r...

Problems solved by technology

Move the chin to the chin rest, and put the eyes on the air pressure mouthpiece of the tonometer body. During the test, the air pressure mouthpiece will blow air pressure into the eyeball, and the device will perform a feedback test on the intraocular pressure to obtain the intraocular pressure data. In actual use, It often occurs that the patient under test has poor self-control ability and uncontrollable frequent blinking, resulting in failure of measurement results or large measurement errors, which requires multiple frequent air blow measurements
