Intraocular pressure meter and method for measuring intraocular pressure

Abstract

The invention relates to the technical field of an intratonometer and a method for measuring intraocular pressure, and the intratonometer comprises a shell and a contact piece; a driving unit; a sensor; a drive control unit; a display unit; a power unit; and the supporting unit is used for contacting the eyebrow bone and the cheekbone of the user. According to the tonometer, the sensor is arranged on the tonometer to sense the pressure value of the contact piece, rotation of the stepping motor is controlled through a program according to the pressure value of the contact piece, then the contact piece is controlled to slowly make contact with the eyelid, and intraocular pressure detection of a user is achieved. When the contact piece makes contact with the eyelids of a user, the contact piece is sensed by the sensor, a program controls the contact piece to apply force to the eyeballs according to sensing data, the elastic reaction information of the eyeballs is sensed, pressure data is collected, and then the intraocular pressure value is obtained through data processing.

Description

technical field [0001] The invention relates to the technical field of a tonometer and a method for measuring intraocular pressure, in particular to a tonometer and a method for measuring intraocular pressure. Background technique [0002] With the development of society and economy, people's living standards continue to improve, and more and more attention has been paid to visual health. Glaucoma is the world's first irreversible blinding eye disease, and it is the cause of blindness for 50% of the blind people in the world. Its incidence rate in all age groups is 1-2%, and the incidence rate of people over 50 years old is as high as 5-6%. , a serious threat to people's visual health. The most external feature of glaucoma is also the cause of blindness, which is high intraocular pressure. Monitoring intraocular pressure is an important means to prevent and treat glaucoma. Tonometers have gradually become more and more familiar medical devices. [0003] Tonometers are comm...

AI Technical Summary

Problems solved by technology

Common tonometers include applanation and indentation, both of which are corneal contact tonometers. Because they require professional operations such as anesthesia and disinfection, and have great safety risks, the operation is very cumbersome and cannot be used at home; non-contact tonometers The tonometer does not require professional operations such as anesthesia and disinfection, and is highly safe, but the high price of about 100,000 yuan makes it impossible to enter ordinary families

Rebound tonometers are specially designed for home use, and safety is not a problem, but the price of 20,000 to 30,000 yuan is still expensive, and it is difficult to be accepted by ordinary families
