Description

Technical Field

[0001] The present invention relates to the field of intelligent medical care, and in particular to an eye pressure monitoring and adaptive adjustment system based on edge computing. Background Art

[0002] With the rapid development of information technology, especially the rapid progress of the Internet of Things (IoT), edge computing and big data technology, smart medical devices are being used more and more widely in various fields. Especially in the field of eye health, the monitoring and regulation of intraocular pressure is crucial to the prevention of eye diseases such as glaucoma. Glaucoma is a disease that causes damage to the optic nerve due to excessive intraocular pressure. If not treated in time, it may cause irreversible eye damage and seriously affect the patient's quality of life.

[0003] At present, many researchers and medical device manufacturers have begun to explore new technologies for monitoring eye pressure. Traditional intraocular pressure measurement usually relies on manual testing in hospitals, using equipment such as applanation tonometers and non-contact tonometers, which usually require professional medical staff to operate, and the accuracy and real-time performance of the measurement results are poor. In recent years, the emergence of portable medical devices has provided new ideas for intraocular pressure monitoring. These devices combine sensor technology with wireless communication technology to improve the accuracy and portability of monitoring. For example, some smartphone-based applications can be used with Bluetooth-connected sensors to help monitor eye pressure in real time. However, these portable devices still have problems with data processing and feedback delays, and cannot achieve real-time adaptive adjustment. And the existing eye pressure monitoring system still has some shortcomings. Many devices have not yet reached the ideal level in terms of data accuracy, real-time performance, and adaptive adjustment capabilities. Although some systems can record changes in patients' intraocular pressure, they lack intelligent analysis and feedback mechanisms and cannot automatically adjust intraocular pressure, which may cause delays in practical applications and threaten patients' health.

[0004] As edge computing continues to develop and mature, it provides new solutions for the application of medical monitoring equipment. Edge computing refers to data processing and analysis near the source of data generation, which reduces the time and bandwidth required for data transmission and helps improve real-time performance and reliability. In eye pressure monitoring, edge computing can quickly analyze the data collected by sensors, thereby achieving real-time monitoring and automatic adjustment of intraocular pressure. By introducing edge computing in devices used for eye pressure monitoring, rapid data processing and response can be achieved, which can effectively improve the performance and user experience of the eye monitoring system.

[0005] In this context, an innovative eye pressure monitoring and adaptive adjustment system is needed, which can not only monitor eye pressure in real time, but also automatically adjust the monitoring and adjustment parameters through adaptive adjustment algorithms according to the needs and eye conditions of different patients, so as to achieve precise control of eye pressure.

[0006] In summary, with the continuous advancement of science and technology, especially the widespread application of technologies such as sensors, wireless communications and edge computing, the construction of a real-time monitoring and adaptive adjustment system for eye pressure has become an inevitable trend. The development of this system can not only improve the quality of life and safety of patients, but also has great social value in medical and health management. It meets the actual needs of current medical technology development and provides new ideas and directions for future eye health management. Summary of the invention
