Visual function detection equipment for ophthalmology department

Abstract

The invention discloses visual function detection equipment for the ophthalmology department, and belongs to the technical field of medical apparatuses. The visual function detection equipment comprises a forehead electrode set, a metencephalon electrode set, two electrode fixing belts and a mainframe, the forehead electrode set and the metencephalon electrode set are in wireless transmission withthe mainframe for data exchange, the electrode fixing belts are elastic belts and are arranged between the forehead electrode set and the metencephalon electrode set, any elastic belt is provided with a length reading device capable of measuring the actual length of the fixing belt in real time, and the metencephalon electrode set is provided with a length receiving device capable of conducting data exchange with the length reading device. Through electrodes, an amplifier, a Bluetooth transmitter and a Bluetooth receiver, a detected voltage signal of the human eyes can be wirelessly transmitted to the mainframe, the mainframe conducts a series of data processing and then obtains the detection result of the visual function, and compared with the prior art, the device is simpler and higherin work efficiency.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an electrode used for ophthalmology visual function detection. Background technique [0002] When performing eye visual function tests such as VEP / ERG, it is necessary to fix multiple electrodes at different positions on the head to obtain potential information, and then evaluate retinal functions, etc., and propose a reasonable treatment plan. [0003] Since the potential information of the human body is a very small voltage difference signal, in order to ensure the stability and non-attenuation of the signal, the signal transmission in the prior art adopts wired transmission. But this brings problems: Under the limitation of wired transmission, the electrodes in the prior art are all connected by wires, and the wires are made of copper wires, which are soft in texture. In the visual function test, multiple electrodes need to be fixed on the head , Multiple ...
