Blue Light Headset for Nocturnal Uterine Contraction Regulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods fail to effectively regulate uterine contractions during nocturnal hours in pregnant females, particularly in preterm labor, due to the lack of understanding and control over circadian signals driving uterine activity.
Innovation Solution
Exposing pregnant females to a light source emitting visible light, specifically with sufficient intensity and blue light spectrum, to suppress endogenous melatonin levels, thereby reducing or preventing nocturnal uterine contractions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If light exposure is applied to suppress melatonin levels, then uterine contraction frequency is reduced, but the complexity of the intervention increases
Solution Approach 1:
The patent replaces complex pharmacological interventions with a simpler optical intervention. Instead of administering drugs to suppress melatonin and reduce contractions, the invention uses light exposure (phototherapy) to achieve the same physiological effect, substituting a mechanical/optical system for a chemical/pharmacological system.
2Reliability
If light therapy is used to regulate nocturnal contractions, then preterm labor is delayed, but the treatment requires precise control of light parameters
Solution Approach 1:
The patent applies phototherapy by changing specific parameters of light exposure: intensity (lux levels), spectral composition (blue light wavelength), and timing (nocturnal hours). By optimizing these parameters, the treatment achieves reliable suppression of melatonin and reduction of uterine contractions, delaying preterm labor while maintaining a relatively simple intervention protocol.
3Productivity
If melatonin suppression is achieved through light exposure, then nocturnal uterine activity is reduced, but the mechanism requires understanding of circadian biology
Solution Approach 1:
The patent uses light as an intermediary to modulate the circadian system. By applying photic stimuli during nocturnal hours, the treatment indirectly suppresses melatonin production through the circadian pacemaker, which in turn reduces uterine contractility. This intermediary approach leverages the natural circadian regulation of both melatonin and uterine activity, providing a physiologically-based treatment mechanism.
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 suppression of melatonin levels leads to a significant decrease in uterine contractions, potentially prolonging pregnancy or delaying preterm birth, as demonstrated by clinical experiments showing a direct correlation between light exposure and reduced contractions.
Implementation Method 1
Exposing pregnant females to light during nocturnal hours decreases their endogenous melatonin levels, which regulates nocturnal uterine contractions
Data Source
AI summary
A method of regulating uterine contractions comprises suppressing a nocturnal endogenous melatonin level of a pregnant female experiencing uterine contractions at night by exposing the pregnant female during nighttime to a light source emitting blue light. The light source may be a headset. The contractions may be measured while the female is exposed to the blue light.
