A breast pump (1, 3) comprising a milk reservoir and a closure member (11, 31) for connection with said reservoir; said closure member comprising a suction bell (12, 32) and a suction pump (14, 34) suitable for single-handed manual operation and including: (a) a cylinder (13, 33) integrally connected with said closure member; (b) a piston means (19, 39) for reciprocating motion within said cylinder between a first or lower position and a second or upper position, and (c) a spring-loaded actuator (10, 30) for interaction with said piston means; wherein said actuator is formed by a yoke means comprising an elongated spring member (18, 38) and said yoke further comprising a pair of elongated lateral legs (16, 17) said yoke means being dimensioned for single-handed manual compression of said lateral legs and for elastically deforming said spring member by said compression so as to upwardly displace said piston means within said cylinder upon said manual compression and permitting said spring member to revert into its first or normal position when said lateral legs are released from said manual compression for returning said piston means into said first or lower position. |
