Abstract

185,521. Del Castillo, M. R. June 10, 1921. Breast pumps.-Air is exhausted from a receiving-chamber E by means of a hand pump K having pivoted arms H closing against the pull of a spring I, and being adapted for use with one hand. A filter G of absorbent cotton is placed between the pump and the receiver, and from the latter a branch pipe leads to a cup A, through a valve C. The outlet pipe F also contains a valve, so that, when in use, on pressing the handles H, milk is withdrawn and collects in the receiver E, and is ejected on allowing the handles to spring apart.
