摘要:
A diaphragm vacuum pump has an electrically operated drive unit and a vacuum diaphragm, which separates a pump chamber into a drive-side part and a drive-remote part and which can be deflected by means of a movable part of the drive unit. The drive unit is an electromagnetic drive unit and the vacuum diaphragm is deflected in the direction of a linear movement generated electromagnetically in the drive unit. Preferably, a ventilation valve is also actuated the movable part. The vacuum pump is relatively small and compact and operates quietly. The vacuum pump is suitable in particular for “hands-free” applications of breastpumps.

摘要:
A device for expressing human breast milk has a breast shield for bearing against a mother's breast, a vacuum pump for generating a vacuum, a line which connects the vacuum pump to the breast shield and is intended for transmitting the vacuum generated to the breast shield, and a chamber. The line ends on the pump side in a first port of the chamber. The chamber has a second port for connection to a milk collecting container. The two ports in the chamber are connected to each other in terms of fluid communication. During the expressing operation, the line forms a milk line for transporting breast milk expressed in the breast shield to the chamber and from the chamber to the milk collecting container. The pump can be designed to be quiet and small.

摘要:
A breast shield has a tubular connector and a funnel that is integrally formed thereon, and is intended for resting on a mother's breast. The funnel widens toward the free side thereof which faces away from the connector. A passage, which extends continuously from a breast-side end of the funnel as far as a pump-side end, being opposite the breast-side end, of the connector, and serves to apply a vacuum to the mother's breast and for the flowing away of the expressed breast milk. The funnel is of more flexible design than the connector, and the funnel has a main region extending over a substantial part of the length thereof with a first opening angle of the passage, and a breast-side end region with a second opening angle of the passage. When not in use, the first opening angle is smaller than the second opening angle. In use, at least the first opening angle can be enlarged by axial pressure on the breast shield. The breast shield is pleasant to wear and minimizes the dead volume.
摘要:
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.

摘要:
A mouthpiece has a bite-off-prevention feature. The mouthpiece has been manufactured from an elastomeric parent material with at least one first component, where a reinforcing component embedded within the parent material forms the bite-off-prevention feature and derives from the same group of substances or group of materials as the first component. The reinforcing component is preferably composed of fibers.
摘要:
A suction pump, in particular a breast pump, comprises a bleed valve with a bleed opening (44, 54, 67), a bleed body (32) which seals the bleed opening and an operating means (8) for operating the bleed body. The bleed body may be operated such that upon opening the valve initially only a partial region of the bleed opening is released and subsequently a greater part thereof or the whole bleed opening is released. Said suction pump provides a large functionality with the smallest size and, furthermore, is cheap to produce and easily assembled.
