Underpressure Milk Expression Device with Infrasound Source
Summary
USPTO published patent application US20260091164A1 for a milk expression device utilizing underpressure and infrasound technology. The device includes a nipple-enclosing wall defining a chamber connectable to an underpressure generator, along with an infrasound source featuring a moveable member. Inventors include YanYk Parulian, Julian Bourquin, Okke Ouweltjes, and Anna Louise Wijnoltz. Application No. 19113061 was filed September 14, 2023.
What changed
USPTO published a patent application for a breast pump device (US20260091164A1) that combines underpressure milk expression with infrasound technology. The device features a nipple-enclosing wall creating a chamber where underpressure is applied to express milk, augmented by an infrasound source containing a moveable member that produces infrasound vibrations. A fluid connection between the chamber and the moveable member allows pressure equalization while controlling fluid communication during member movement to enhance varying pressure effects on the breast.
This patent application represents prior art that manufacturers of breast pumps and lactation devices should monitor for potential licensing implications or competitive intelligence purposes. No compliance actions are required; this is an informational publication of a patent application seeking intellectual property protection. Manufacturers developing similar underpressure milk expression technology may wish to assess whether their products could infringe this pending application once granted.

Abstract
Provided is a device (100) for expressing milk from a mammalian breast (102). The device comprises a nipple-enclosing wall (104) for interfacing with a nipple-comprising region (106) of the breast to define a chamber (108) between the nipple-enclosing wall and the nipple-comprising region of the breast in which an underpressure is providable. The chamber is, for example, connectable to an underpressure generator for decreasing a pressure in the chamber. The underpressure may assist milk to be expressed from the breast and/or may assist in retaining the interface between the nipple-enclosing wall and the nipple-comprising region. The device comprises an infrasound source (112) for producing infrasound. The infrasound souce comprises a moveable member (114) whose movement produces infrasound. The moveable member has a first side (114A) facing and in fluid communication with the chamber, and a second side (114B) opposite the first side. The second side is outside the chamber. A fluid connection (116) is provided between the chamber and the second side. The fluid connection may provide pressure equalization between the chamber and the second side of the moveable member so that both the first side and the second side of the moveable member experience the underpressure. The fluid connection is nonetheless configured to control fluid communication between the chamber and the second side of the moveable member during the movement of the moveable member and thus the fluid connection assists to control, e.g. enhance, a varying pressure experienced by the breast that is caused by the movement of the moveable member.
