Manual breast pump

A manual breast pump adapted for one-handed operation, comprising:

• a pump body defining an inlet, an outlet and a vacuum port, the outlet defining structure for sealingly engaging an opening in a milk-receiving vessel;
• a pump chamber in fluid communication with the vacuum port;
• a stationary handle connected to the pump body;
• a movable handle connected to the manual breast pump and spaced from the stationary handle so that both handles can be grasped simultaneously between the palm and fingers of a hand during use, the movable handle being movable with respect to the stationary handle;
• a piston disposed within the pump chamber, the piston being operably connected to the movable handle so that movement of the movable handle with respect to the stationary handle results in movement of the piston within the pump chamber to create a vacuum at the vacuum port;
• and wherein
• the pump chamber is arcuate, and the piston is movable along an arcuate path within the arcuate pump chamber, whereby operation of the manual breast pump is achieved using a natural and comfortable pumping motion when the handles are squeezed between the palm and fingers of a hand.
