Automatic safety protection blue light phototherapy equipment

By introducing a visual acquisition and image recognition module into the blue light therapy device, the device automatically identifies the wearing status of the eye mask and cuts off the blue light output, thus solving the safety hazard caused by loose eye masks in newborn blue light therapy devices, reducing equipment upgrade costs, and making it suitable for both new and old devices, thereby improving safety and compatibility.

AI Technical Summary

Technical Problem

Existing neonatal blue light therapy devices are prone to eye shielding loosening and falling off during use, making 24-hour real-time monitoring impossible. This results in blue light directly irradiating the newborn's eyes, posing a safety hazard of retinal damage and vision loss. Furthermore, existing devices with safety protection functions are not compatible with older instruments, leading to high upgrade costs.

Method used

Design an automatic safety protection blue light phototherapy device, including a blue light phototherapy instrument body and adaptable external components. It adopts a visual acquisition module, an image recognition module and a control alarm module to identify the wearing status of the eye mask in real time, automatically cut off the blue light output and alarm, and is compatible with new and old equipment.

Benefits of technology

It achieves 24-hour real-time automatic recognition of the eye mask wearing status, avoids damage to newborns' eyes from blue light exposure, reduces equipment upgrade costs, facilitates large-scale promotion and application, and is compatible with different scenarios and phototherapy eye masks.

Abstract

The invention discloses an automatic safety protection blue light phototherapy device, which comprises a blue light phototherapy instrument main body and an adaptive external assembly, and is characterized in that the adaptive external assembly is provided with an adaptive connection interface which is used for being detachably connected with a blue light phototherapy instrument and realizing linkage control and power supply of blue light output, and the adaptive external assembly comprises a visual acquisition module, a control module and a power supply module, the image acquisition module is used for acquiring image sequences of neonatal head and eye areas in real time; the image recognition module is configured to analyze the image sequence based on a pre-trained eyeshade recognition model so as to recognize the wearing state of the neonatal phototherapy eyeshade; and the control alarm module is in signal connection with the image recognition module and a blue light output unit of the blue light phototherapy instrument main body, and is configured to automatically cut off a power supply of the blue light output unit and trigger an alarm when it is recognized that the eyeshade is worn abnormally. And the phototherapy irradiation can be stopped immediately when the eyeshade is worn abnormally, so that the eyes of the newborn are prevented from being injured by blue light.
