Abstract: A breast milk pump that is easier to disassemble for cleaning and is easier to reassemble. It includes a housing, a cup-like displacement chamber a connection channel and a milk collection container releasably attached. A suction bell is connected to an inlet of the connection channel. It further includes a cup-like membrane element and a coupling element and a lever with rotatable mounting.

Abstract: A breast milk pump having an electric motor, a pump driven by the motor, a suction cup, an electrically activated first three-way valve in a suction line, an electrically activated second three-way valve in a pressure line, an electronic control system, which sets the electric motor into an operating mode or an idle mode depending on an activation of a switch; in the operating mode, it operates the electric motor and the electrically activated first and second three-way valves in cycles, which comprise a suction phase, in which the electric motor is switched on, the inlet of the pump is connected to the suction cup via the first three-way valve and a floater valve, the pump outlet is connected via the second three-way valve.

Abstract: An electrical pump for breast milk, having an electric motor, a pump, at least one suction cup, a suction line connecting the suction cup to the pump, an outlet for breast milk connected to the suction cup, a venting line connected to the suction cup, an electrically activated venting valve in the venting line, an electronic control system which adjusts the speed of the electric motor and the electrically activated venting valve to switch the electric motor on and off to allow the electric motor to run at a desired speed and to operate the electric motor continuously and/or in cycles, in which the electric motor is alternately switched on and off, and the electronic control system opens the venting valve when the electric motor is switched off, and closes the venting valve when the electric motor is switched on.

Abstract: A breast pump for pumping down breast milk, with a cylindrical hollow piston with at least one deepening circulating on the outside on the lower end with respect to the cylindrical superficies surface of the hollow piston, a suction cup, which is connected to the tipper end of the hollow piston via a passage for fluid, a soft elastic compensation element (8) between the hollow piston and the bearing surface of the suction cup, at least one circulating sealing element made of a soft elastic material, inserted into the deepening, and a cylinder with a closed lower end, in which the hollow piston is axially movable, wherein the superficies surface of the hollow piston is guided on an inner wall of the cylinder, the sealing element is sealingly arranged between the inner wall of the cylinder and the hollow piston, and at least the suction cup is arranged outside of the cylinder.

Abstract: A magazine body (2) with a plurality of radial magazine chambers (3) by insertion in an axial fastening device (20) with chamber inlets (4) is made to coincide with a medium passage opening (30) and with outlets (5) is made to coincide with a connecting opening (33) of a suction head (17), so that the medium occurs in uninterrupted manner at the inlets (4). The suction head (17) evacuates all the magazine chambers (3) and then filled via the passage (30) from a medium supply (12) and against a medium retaining device (36). With the ejection of the filled magazine chambers (33) the inlets and outlets (4, 5) are closed in medium-tight manner by stripping from closure parts (8, 9).

Abstract: In a discharge apparatus (1) on a basic body (8) is provided a pneumatic pump (19) and axially adjacent thereto a casing chamber (14) for receiving a magazine (15) for individual doses of a pulverulent or similar medium, whose magazine chamber (30) can be transferred into a discharge position, in which it is connected by one inlet end (46) and one outlet end (47) to a feed path (20) for the pumped air. At remote ends of the basic body (8) are provided pressure handles (5, 6) for the discharge actuation and a handle (7) for indexing or replacing a magazine body (16). Opening devices (50, 51) are used for the automatic opening of the magazine chamber (30) on transfer into the discharge position. This leads to a very reliable operation in the case of compact construction and easy handling.
