LINER AND BREAST INTERFACE FOR BREAST PUMP Russian patent published in 2018 - IPC A61M1/06 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment. Liner for use in a breast interface includes a front section including a front wall part defining a breast contact surface and an opening provided in said breast contact surface; said breast contact surface being configured to abut a woman's breast during use, while the nipple of the breast protrudes at least partially through said opening. Middle section is located between the front and rear sections and is connected to the rear end of the wall part of the base of the front section. Middle section is configured to compress on both sides of the nipple of the breast during operation and to stretch or expand along a first radial direction and compress or contract along a second radial direction perpendicular to the first radial direction. Rear section is connected to the front section and includes a tubular wall part having an opening in the rear part. Front and rear sections together at least partially form a milk passage that extends from the opening in the breast contact surface to the opening in the rear part of the tubular wall part. Liner is designed for a use orientation in which the longitudinal axis of the front section extends substantially horizontally, while the tubular wall part of the rear section has a lower inner surface part which partially defines the milk passage and which, in said use orientation, when viewed in the rearward direction, is inclined downward relative to the longitudinal axis. Interface for a breast including a liner and a breast pump including an interface are disclosed.

EFFECT: technical result consists in improving the intake of milk, improving convenience of use and reducing decantation time.
