Compact LED Phototherapy Panel for Incubator X-Ray Cassette Tray
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current phototherapy systems for infants in incubators or baby warmers are limited by the need for bulky light sources that do not efficiently utilize the available space within the X-ray cassette tray, and they often require direct exposure to blue light, which can have side effects on caregivers.
Innovation Solution
A compact phototherapy panel with a transparent or translucent housing and LED light sources that fit within the X-ray cassette tray, emitting electromagnetic radiation through a transparent or translucent surface to minimize direct exposure and reduce caregiver exposure risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional phototherapy systems use conventional light sources, then sufficient light intensity for phototherapy can be achieved, but the system becomes bulky and cannot fit in the X-ray cassette tray
Solution Approach 1:
The patent replaces conventional mechanical light sources (incandescent bulbs, halogen lamps) with LED technology. This substitution enables compact phototherapy panels with dimensions suitable for X-ray cassette trays while maintaining sufficient light intensity for effective phototherapy treatment of jaundiced infants.
Solution Approach 2:
The patent changes the physical parameters of the light source by using high-intensity LEDs that emit in the blue spectrum (460-490 nm). This parameter change allows achieving adequate irradiance levels in a compact form factor, resolving the contradiction between small size and sufficient light intensity.
2Reliability
If blue light is emitted directly for phototherapy, then effective treatment of jaundice can be provided, but caregivers are exposed to harmful blue light
Solution Approach 1:
The patent introduces a translucent diffuser panel as an intermediary between the LED light source and the infant. This diffuser transmits the therapeutic blue light to the infant while scattering and reducing the direct exposure to caregivers, thereby maintaining phototherapy effectiveness while minimizing harmful effects on caregivers.
Solution Approach 2:
The patent uses LEDs that emit blue light (460-490 nm) which is the optimal wavelength for phototherapy. The translucent housing material is selected to transmit this blue light effectively while diffusing it to reduce direct exposure, maintaining treatment reliability while reducing harmful factors.
3Volume of moving object
If the phototherapy panel is made compact to fit in X-ray cassette tray, then space utilization is optimized, but manufacturing complexity increases
Solution Approach 1:
The patent designs a universal phototherapy panel that serves multiple functions: it provides phototherapy treatment, fits within the X-ray cassette tray infrastructure of existing incubators, and can be easily installed and removed. The standardized dimensions and simple housing structure reduce manufacturing complexity despite the compact size requirement.
Solution Approach 2:
The patent uses a thin, translucent housing that is both compact and easy to manufacture. The housing acts as a diffuser and protective enclosure, combining multiple functions in a single thin component that simplifies the overall manufacturing process while maintaining the compact form factor needed for cassette tray integration.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The compact design allows for effective phototherapy while reducing exposure to caregivers and optimizing space, ensuring safe and efficient treatment of jaundice in infants without direct blue light exposure.
Implementation Method 1
The panel comprises a housing (8) and one or more light sources (11). The housing (8) is configured to carry the one or more light sources (11). The housing (8) has a light emitting surface (6) that is transparent or translucent
Implementation Method 2
electromagnetic radiation emitted by the one or more light sources is guided through the light emitting surface of the housing to provide phototherapy to the infant
