A pumpless silent negative pressure system comprises: a horn cover, a cylinder is provided to its lower end; a software arranged inside the horn cover, the rear end of the software is provided with one or more coils. The software's center is provided with a cavity for generating negative pressure, the front end of the software is provided with an opening for adhering to the object to be sucked, the rear end of the software is extended with a cavity inside the cavity and having a return stress rebound and a single or a single or a plurality of elastic inner concave parts of a plurality of negative pressure chambers, the front end surface of the elastic inner concave part forms a negative pressure chamber film and a stroking type promoting milk film, and the end of the elastic inner concave part is provided with a magnet.

An apparatus for allowing a user to use a breast pump while resting. The apparatus includes a resting pump mount having a divot sufficiently sized to fit a user's breast. The body substantially holds shape and is at least partially compressible. The apparatus may include comfort features, attached breast pumps, or receptacles to allow for attachment of a breast pump.

Disclosed herein are various techniques and devices for detecting a level of fluid within a fluid collection receptacle. In one embodiment, a pressure sensor connected to a bottle is provided. The pressure sensor detects air pressure in the bottle as the bottle is filled with a liquid and provides information to determine a volume of the liquid in the bottle.

A breast pump system comprises at least one wearable milk collection hub connected via an air line to a combined external air pump and control unit. Each milk collection hub comprises: (a) a breast shield made up of a breast flange and a nipple tunnel; (b) a flexible diaphragm that is configured to prevent milk from reaching the external air pump; (c) an outer shell that is configured to removably attach to the breast shield, such that, when attached, the breast shield and outer shell form a vessel for collecting milk; and (d) a diaphragm cap that is configured to be secured over the diaphragm, forms part of the front face of the outer shell, and includes a port connected to the air line.

A breast pump device (1) comprises an expression kit (2), a vacuum unit (3), and a conduit (5) for establishing an air path between an air outlet (27) of the expression kit (2) and an air inlet (35) of the vacuum unit (3). The expression kit (2) is equipped with a barrier portion (26) for preventing milk leakage from the expression kit (2) towards the hose (5) and the vacuum unit (3). In case some droplets of milk enter the barrier portion (26) and/or drawn through the barrier portion (26) by an ongoing pumping action, aspects of the behavior of the motor (32) for driving the pump (31) are influenced, and the insight that this happens is used for terminating operation of the motor (32) as soon as a too large deviation of one or more operational characteristics of the motor (32) with respect to a reference is found.
