A connector for use in single and double breast pumping modes of operation of a breast pump has a tubular housing with an internal wall extending across the housing interior and dividing it into two chambers. One chamber has a first nipple extending from the internal wall and into air communication with the second chamber, the first nipple being adapted for attachment of an air tube leading to a breast shield in a single-pumping mode. The other chamber has two nipples extending from the internal wall each of which are in air communication the first chamber. Preferably, the three nipples are joined through a common air/vacuum junction. The second and third nipples are likewise adapted for attachment of an air tube thereto in a double-pumping mode. A detachable connection is provided so that the tubular housing can be alternately attached into the vacuum line with either the first or second chambers exposed for attachment of one or more air tubes to the exposed nipples. An adapter is preferably provided which receives a vacuum tube from a vacuum source in one side and has a tubular part to which either side of the connector's tubular housing can be screwed together with the adapter to enclose one or the other of the two chambers, leaving the nipple(s) of the other chamber exposed for air tube attachment. |
