Mechanical Teat Stimulation for Enhanced Milk Letdown

A milk expression system that optimizes pumping parameters based on the timing and intensity of the milk ejection reflex. The system employs an adaptive pressure profile that maintains a non-zero baseline under-pressure during the milk ejection phase, rather than relying solely on the vacuum level. This profile is generated by detecting the milk ejection reflex and adapting the pressure settings to match the user's milk flow characteristics. The system incorporates features like smart classifier-based detection of milk ejection onset, dynamic pressure adjustment based on milk delivery, and real-time monitoring of milk flow and duct dimensions.

Milk liner for milking apparatus that improves milk extraction and reduces teat discomfort by generating a massage effect. The liner has a ribbed portion and an unribbed portion that sequentially collapse inward when pressure differences are applied. Alternatively, the liner has a tapering portion that causes progressive inward collapse. This peristaltic massage action moves milk up the teat, reducing fluid accumulation and teat congestion compared to conventional liners. The liners are used in teat cups of milking apparatuses that apply suction and cyclic pressure variations to the liners.

A breast pump with a built-in massage system that enables mothers to enhance their breastfeeding experience through deliberate breast manipulation. The pump incorporates a specialized massage unit within its breast support system, allowing mothers to target specific areas of their breasts for improved milk flow and comfort. This innovative design enables mothers to develop a personalized massage routine that complements their breastfeeding technique, promoting effective milk production and comfort during feeding.

A breast pump that mimics the natural suckling action of an infant during breastfeeding, providing a more effective and comfortable milk collection experience. The pump features a unique interface system that combines a funnel-shaped breast shield with a hydraulic bladder system. The bladder system employs a dynamic compression mechanism that alternates between a more resilient and less resilient section, creating a controlled suction and compression action against the breast tissue. This patented interface system enables the pump to replicate the natural milk ejection reflex (MER) that occurs during breastfeeding, while also providing a more natural and comfortable milk collection experience compared to traditional vacuum-based breast pumps.

A breast pump that more closely mimics the natural suckling action of an infant during breastfeeding, providing a more effective and natural milk collection experience. The pump features a unique interface system that combines a hydraulic stimulation mechanism with a nipple compression system, enabling the creation of a milk ejection reflex (MER) that is more physiological than traditional vacuum extraction methods. The interface system comprises a funnel-shaped breast shield, a nipple tunnel, and a hydraulic pump that operates through a valve switch. The system utilizes a combination of the funnel-shaped shield and the nipple tunnel to create the MER, while the hydraulic pump delivers controlled pressure to the nipple to compress it against the breast tissue. The valve switch allows for selective activation of either the hydraulic stimulation or nipple compression mechanism, enabling the user to choose the desired milk collection method.

A breast pump design that enhances milk expression by mimicking the natural sucking motion of an infant. The pump features a curved, flexible element that deforms in response to pressure, creating a peristaltic motion that stimulates the nipple and triggers the milk ejection reflex. This motion is achieved through a unique, resonant frequency range of 0.5-3 Hz, specifically tailored to the natural frequency of infant suckling. The design allows both stimulating and expression phases, with the flexible element adapting to the pumping action. The pump's curved shape and pressure source work together to create a natural, ergonomic feeding experience that reduces discomfort and pain during breastfeeding.

A teatcup liner that provides enhanced teat massage and congestion relief during milking by ensuring complete collapse of the upper barrel section during the milking process. The liner features a specially designed barrel shape with a triangular cross-section that creates a seal when the liner is applied to the teat, preventing vacuum leaks during milking. The liner's unique design ensures that the upper barrel section collapses completely during milking, providing a more effective teat massage and relief of teat tissue congestion compared to conventional teatcup liners.

Mechanically milking lactating animals through continuous vacuum application to the teat end, enabling optimized milking characteristics. The method employs a teat cup with a flexible liner that is precisely positioned within the cup. The liner features a pressure chamber that maintains a constant milking vacuum pressure throughout the milking cycle, eliminating the discontinuous vacuum fluctuations characteristic of conventional milking. The teat cup's unique design ensures consistent teat-end pressure, while the liner's pressure management system prevents liner slippage and maintains optimal teat condition.
