Flexible Light Emitting Pad for Infant Phototherapy Swaddling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current phototherapy methods for treating jaundice in infants, especially in cost-sensitive environments, are ineffective due to the need for external light sources and lack of swaddling options, leading to disrupted treatments and inadequate light dosage.
Innovation Solution
A flexible light emitting pad integrated with light sources, which can be wrapped around an infant's torso, providing 360-degree coverage without external lamps, and a garment to maintain the pad's position, ensuring continuous treatment while allowing swaddling and reducing movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If overhead lights are used for phototherapy, then light dosage is adequate, but the infant cannot be swaddled and treatment is disrupted
Solution Approach 1:
The patent transitions from overhead illumination (vertical dimension) to circumferential illumination around the infant's torso (horizontal dimension). The flexible light-emitting pad wraps around the infant's body, providing 360-degree light exposure while allowing the infant to be swaddled in traditional positioning, thus resolving the contradiction between adequate light dosage and swaddling capability.
Solution Approach 2:
The patent employs a flexible light-emitting pad that can be wrapped around the infant's torso. This flexible structure conforms to the infant's body shape, provides uniform circumferential illumination, and allows the infant to be swaddled comfortably, simultaneously achieving adequate light dosage and maintaining swaddling capability.
2Illumination intensity
If the infant is not swaddled during phototherapy, then light exposure is adequate, but the infant becomes distressed and treatment stops
Solution Approach 1:
By changing the illumination geometry from overhead to circumferential wrapping, the system provides adequate light exposure while allowing the infant to be swaddled in a secure, comfortable position. This maintains treatment continuity as the infant remains calm and swaddled throughout the therapy session.
3Ease of operation
If blanket phototherapy is used to allow swaddling, then infant comfort is improved, but light dosage is insufficient
Solution Approach 1:
The flexible light-emitting pad wraps around the infant's torso, providing circumferential illumination that ensures adequate light dosage to all exposed skin surfaces. The pad's flexibility allows it to conform to the infant's body while maintaining close contact, ensuring sufficient light penetration and dosage while the infant remains swaddled and comfortable.
Solution Approach 2:
The transition from overhead illumination to 360-degree circumferential illumination ensures that light reaches all surfaces of the infant's torso effectively, achieving adequate dosage while maintaining swaddling capability and infant comfort.
4Illumination intensity
If external light sources are used, then light intensity is sufficient, but device complexity and cost increase
Solution Approach 1:
The patent integrates the light sources directly into the flexible pad that contacts the infant's skin, eliminating the need for separate external light sources, positioning mechanisms, and complex mounting systems. This integration simplifies the overall device structure, reduces cost, and maintains sufficient light intensity for effective phototherapy.
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 solution enables effective phototherapy with full-body light exposure, reducing treatment interruptions and ensuring adequate light dosage, while being cost-effective and suitable for both full-term and premature infants.
Implementation Method 1
Exposing the infant's skin to certain types of light will quickly reduce the bilirubin to a safe level. Because treating jaundice typically involves exposing a baby's skin to overhead lights (the light converting bilirubin to another molecule that kidneys typically can filter)
Implementation Method 2
the flexible light emitting pad additionally includes a light guide and the light emitted by the light sources is received, propagated, and emitted by the light guide
Data Source
AI summary
A phototherapy device including a flexible light emitting pad is provided. The phototherapy device allows an infant to be swaddled while the infant simultaneously receives phototherapy treatment on his/her front, back, and sides without the use of external light sources.
