A suction pump, in particular a breast pump, comprises a bleed valve with a bleed opening, a bleed body which seals the bleed opening and an operating means 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. The suction pump provides a large functionality with the smallest size and, furthermore, is cheap to produce and easily assembled.

Membrane pump with air release valve

A teat unit has a flexible teat, a receiving head and a dimensionally stable base part. The teat is arranged on the receiving head. The receiving head and the base part are connected to each other by a releasable plug connection, and the receiving head has a securing element for securing the teat unit on a drinks container.

Membrane pump with bleed valve

A teat unit has a flexible teat, a receiving head and a dimensionally stable base part. The teat is arranged on the receiving head. The receiving head and the base part are connected to each other by a releasable plug connection, and the receiving head has a securing element for securing the teat unit on a drinks container. This teat unit permits a great many possible configurations of the individual parts and, therefore, an optimization of their individual functions.

A teat for connection to a receiving unit of a drink container has a main body and, adjoining the main body and tapered relative to the main body, a mouthpiece with at least one suction opening and a free end. The teat has a first connector element for connection to the receiving unit, and a second connector element for connection to the receiving unit, and a suction channel. The suction channel extends within the mouthpiece, opens via a first end into the suction opening and is directed via a second end towards the main body. This second end forms the first connector element for a substantially leak-tight connection to the receiving unit. The main body is designed such that it can be turned back towards the free end of the mouthpiece. The teat is designed such that it can be turned back at least a second location. The teat according to the invention can be connected to the feeding bottle in a simple and hygienic manner, is easy to clean and permits a feeding action that is as true to nature as possible.
