Abstract
A breast pump includes a platform resting on the floor or other support and a treadle having a convex surface resting on the platform, permitting a pivoting or see-saw motion of the treadle. A bellows is connected between the treadle and the platform, forming a variable displacement chamber. A flexible hose connects the chamber to a reservoir including a container, such as a baby bottle, and an adaptor attached to the bottle as a cap. There is no valve controlling the flow of air to or from the reservoir, thereby providing complete and precise control of the pressure in the reservoir.

A foot operated breast pump comprising:
- (a) a reservoir including a first fitting for placement on a woman's breast and a second fitting for attachment to a source of vacuum;
- (b) a bi-directional pump including
- (i) a platform,
- (ii) a treadle resting on said platform, and
- (iii) a variable displacement chamber connected between said treadle and said platform;
- (c) a hose connecting said chamber to said second fitting;
- and
- wherein motion of said treadle in a first direction relative to said platform causes said chamber to increase in volume and decrease the pressure in said reservoir, and motion of said treadle in a second direction relative to said platform causes said chamber to decrease in volume and increase the pressure in said reservoir.
A foot operated breast pump comprising:
- a reservoir including a first fitting for placement on a woman's breast and a second fitting;
- a bidirectional pump for increasing or decreasing the pressure within said reservoir;
- a hose connecting said pump to said second fitting;
- and
- wherein the connection between the chamber and the reservoir is unobstructed and said reservoir can be pressurized or evacuated by operation of said pump.
