Abstract: The device according to the invention for connecting a suction hose has a connecting piece which is designed in such a way that the suction hose can be pushed over a region of the connecting piece in a sealing manner. The device also comprises a sleeve which can be pushed over the aforementioned region of the connecting piece, at least partially covering said piece and leaving room between the sleeve and the connecting piece for the suction hose. The connection between the sleeve and the connecting piece can only be separated by the destruction of at least one of said two parts. The design of the exterior of the sleeve prevents a second suction hose from lying in a sealing manner against the sleeve. A suction hose that is connected in a sealing manner to the claimed device can therefore not be removed without destroying the device. In addition, it is impossible to push a hose with a greater diameter onto the sleeve in a sealing manner.

When the solenoid relief valve is activated, negative pressure in the second tube and in the breast shield is rapidly removed. The control circuit board controls the first and second vacuum sources and the solenoid relief valve.

Abstract: The present invention provides a breastshield for use in a breastpumping system for expressing milk, the breastshield being of such a construction that substantially limits the amount of air between the breast/nipple and the breastshield surrounding the breast/nipple, and most preferably virtually eliminates any air at least in the area of the breast and nipple. In some embodiments, any air in the breastpumping system is substantially eliminated. With the amount of air limited, the mechanism used for generating the pressure difference in the breastshield (e.g., vacuum or negative pressure), such as a diaphragm pump, does not need to do as much work. Less energy is required for the expression of milk, and thus the size of pump used can be decreased, thereby reducing the overall cost of the device.
