Intelligent portable hand-held vision screening instrument and optometry method

Abstract

The invention belongs to the technical field of medical optometry equipment and especially relates to an intelligent portable hand-held vision screening instrument and an optometry method. The instrument comprises an optometry system, a camera shooting system, an integral control system and a wireless communication system which are connected to a central processing unit, wherein the optometry system is composed of a light source, a diaphragm and a lens and is used for emission of the light source, diaphragm isolation and lens transmission; functions of distance and temperature measurement are achieved through combination of an ultrasonic ranging and a temperature sensor; the optometry system can shoot eye images by an infrared lens and a visible light lens; the integral control system executes different modes including a preview mode, a camera shooting mode and a checking mode; the wireless communication system carries out card reading functions of a social insurance card and a medical service card as well as wireless data transmission; and the central processing unit carries out collection and processing of data, image recognition, gray analysis and diopter computation. The intelligent portable hand-held vision screening instrument is connected to an intelligent medical cloud platform by a wireless communication system.

Description

technical field [0001] The invention belongs to the technical field of medical optometry equipment, and in particular relates to an intelligent portable hand-held vision screening instrument and an optometry method. Background technique [0002] From the perspective of medical and health development, automation / intelligence, precision, digitization and remoteness are the inevitable trends of medical development in the future. Foreign countries have carried out digitization, automation, and remote transformation in the last century, and domestic medical care is now undergoing remote, intelligent, and digital improvements in various industries. With the development of the Internet of Things technology, the traditional medical methods gradually have shortcomings such as low degree of automation and limited medical resources, which will inevitably lead to continuous innovation of medical testing tools. Smart healthcare is the result of the application of the Internet of Things ...

AI Technical Summary

Problems solved by technology

The existing technology mainly has the following disadvantages: when the device is used, the interpupillary distance of the human eye is ignored, and the calculation error is relatively large; when the device is used by itself, it is difficult to identify the position of the human eye, and the device takes a long time to adjust the distance. The position of the lens needs to be adjusted many times, which is difficult for children and the elderly to use; when the product is used by a large number of people, it is more complicated to distinguish personal information, which is prone to errors, and the amount of data is large, making it inconvenient to record

The current tester is mainly inconvenient for users to test. They need to sit at a fixed position and a fixed distance. It takes a long time to adjust the camera, and the human error is large.

And when the number of users is large, the workload of filling in personal information is huge, and the information filling is complicated and error-prone
