Breast Pump Breathing Guidance System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Breast milk expression using existing breast pumps can be challenging due to user stress, which inhibits the release of the hormone oxytocin, essential for milk ejection, leading to inefficient milk extraction and potential rapid diminishment of milk supply.
Innovation Solution
A breast pump system that incorporates a breathing guidance mechanism to help users follow a suggested breathing pattern, either through synchronized pumping frequency or independent stimuli, to reduce stress and promote relaxation, thereby facilitating the release of oxytocin and effective milk expression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a breast pump is used to extract milk, then milk extraction can occur when the baby is unable to extract milk or when the mother is separated from the baby, but user stress inhibits oxytocin release and reduces milk expression effectiveness
Solution Approach 1:
The patent introduces breathing guidance as an intermediary element between the user and the milk extraction process. The system provides auditory or visual breathing cues that mediate the user's physiological state, promoting relaxation and oxytocin release without directly interfering with the pump's mechanical function. This intermediary approach addresses the stress problem while preserving milk extraction effectiveness.
Solution Approach 2:
The system monitors and responds to changes in user physiological parameters (breathing rate, heart rate variability) to dynamically adjust the breathing guidance feedback. By detecting parameter changes that indicate stress or relaxation states, the system can adaptively modify breathing cues to optimize the user's physiological state for milk expression, thereby improving extraction effectiveness while managing stress.
2Speed
If the pumping frequency is increased to improve milk extraction speed, then productivity increases, but user stress may increase and inhibit oxytocin release
Solution Approach 1:
The patent employs periodic breathing guidance cues that are synchronized with or independent of the pumping frequency. These periodic auditory or visual signals guide the user through controlled breathing cycles, creating a rhythmic relaxation effect that counteracts stress induced by faster pumping. The periodic nature of the breathing cues helps maintain oxytocin release even at higher extraction speeds.
Solution Approach 2:
The system incorporates feedback mechanisms that monitor user physiological responses (breathing rate, heart rate variability) and adjust the breathing guidance in real-time. When the system detects signs of stress during high-speed pumping, it modifies the breathing cues to promote relaxation, thereby maintaining oxytocin release and milk expression effectiveness despite increased extraction speed.
3Productivity
If auditory stimulus is provided to facilitate milk ejection reflex, then oxytocin release is promoted, but device complexity increases
Solution Approach 1:
The patent designs the breathing guidance mechanism to serve multiple functions: it provides relaxation guidance, synchronizes with pumping cycles, and offers stress reduction. By making the same component multi-functional, the patent avoids adding separate dedicated systems for each function, thereby reducing overall device complexity while still achieving improved milk ejection reflex initiation.
Solution Approach 2:
The system utilizes the user's own breathing patterns and physiological responses as the basis for the guidance feedback. Rather than requiring complex external monitoring equipment, the system can detect breathing rate and heart rate variability through simple sensors integrated into the pump interface, and uses this self-generated data to provide appropriate breathing cues, reducing the need for complex external systems.

AI summary
A breast pump system (1) comprises a breast pump arranged to extract milk from a user; and a breathing guidance means configured to provide a suggested breathing pattern to the user. The breathing guidance means may be produced by a motorised breast pump unit (10), or may be a series of stimuli at a stimuli frequency, which are perceivable by the user. The system (1) may include a heart rate monitor for measuring the heart rate of the user, and the suggested breathing pattern may be coupled to the measured heart rate.
