Problems solved by technology

For example, optical fiber pickup, laser interference pickup, capacitive pickup, and mechanical contact pickup cannot measure resonance signals when the eyelids are closed, and ultrasound Doppler is difficult to distinguish between eyelid vibration and eyeball vibration when the eyelids are closed signal of
Therefore, it is difficult for this type of intraocular pressure monitor to realize night monitoring

Embodiment Construction

[0046] As shown in Figure 1, the intraocular pressure monitoring device of the present invention includes a spectacle frame 6, a magnetic vibrator 4 and a processing module 7, the spectacle frame 6 is placed in front of the eyes, and the processing module 7 is arranged on the spectacle tripod 62 close to the spectacle frame 61, the magnon 4 is worn on the eyeball 5, and the spectacle frame 6 is provided with a coil that can generate an induced magnetic field when it is energized; the magsonon 4 is excited by an external magnetic field to be close to the eyeball 5 and drive the eyeball 5 to vibrate , following the vibration of the eyeball 5 at the same time, and generating an induced electromotive force in the coil in the spectacle frame 6; the processing module 7 produces a dust signal so that the coil in the spectacle frame 6 generates a dust-induced magnetic field, and measures the induced electromotive force by the principle of magnetic induction to obtain The vibration info...

Abstract

An eye pressure monitor is composed of a spectacle frame with coil in it for generating an induced magnetic field, a magnetic vibrator for exciting the vibration of eye ball by external magnetic field and generating an inductive E.M.F in said coil, and a processing module for generating a signal to generate said induced magnetic field, measuring its inductive E.M.F, and sequentially obtaining the vibration information of eye ball, the resonance frequency of cornea and eye pressure.

Description

technical field [0001] The invention relates to an intraocular pressure monitoring device, in particular to an intraocular pressure monitoring device using a magnetic vibration sensor and a resonance principle. Background technique [0002] At present, intraocular pressure monitoring is of great significance for the diagnosis and treatment of glaucoma, especially a device that can monitor intraocular pressure for 24 hours is an urgently needed equipment for glaucoma diagnosis and medical research. [0003] Currently known intraocular pressure monitoring devices mainly include the following three types: implantable type, patch type and resonance type. Its description is as follows: [0004] The first category: implantable [0005] This type of intraocular pressure monitor implants a sensor in the anterior chamber, and directly senses the pressure of aqueous humor through the sensor. Sensors are divided into passive sensors and active sensors. [0006] The passive sensor c...
