Embodiment Construction

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0028] The design and manufacture of intraocular pressure sensors should not only consider the sensitivity of measurement, but also fully consider the comfort, safety and portability of patients. If the integrated chip sensor is used, the chip needs to be transparent and flexible, and the thickness must be between 50-100 μm after being embedded in...

Abstract

Embodiment of the invention provides an intraocular pressure monitoring sensor. The sensor includes a corneal contact lens, a strain induction circuit and a signal processing module; the corneal contact lens is used for being in match fitting with the eyeball shape of a user; the strain induction circuit is used for inducing the eyeball curvature change of the user and converting the eyeball curvature change into an electrical signal, and the strain induction circuit consists of a graphene material; and the signal processing module is used for processing the electrical signal. The sensor adopts graphene as the strain induction circuit material in the sensor; and compared with metal materials adopted in the prior art, the graphene is a transparent flexible material, and as the excellent electrical and mechanical properties of the graphene, the sensor can be more sensitive on the changes of eye curvature, large changes of graphene resistors can be caused by tiny changes of the eye curvature, so that the changes can be detected, and therefore, the sensitivity of the sensor can be enhanced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of medical devices, in particular to an intraocular pressure monitoring sensor. Background technique [0002] Glaucoma is the second blinding eye disease in the world. According to the statistics of the World Health Organization, the number of glaucoma patients in the world is increasing year by year. It is estimated that by 2020, there will be more than 80 million glaucoma patients in the world, and there will be more than 80 million glaucoma patients in my country. 20 million glaucoma patients will become the country with the largest number of glaucoma patients in the world. [0003] Studies have shown that elevated intraocular pressure is the main cause of glaucoma. Intraocular pressure refers to the balanced pressure exerted by the contents of the eye on the eyeball wall. The normal range of intraocular pressure is 10-21mmHg, which is used to maintain the shape of the eyeball and ens...
