Abstract: A breast pump includes a body including a hood attachment portion, a bottle attachment portion, and an inner passage extending between the hood attachment portion and the bottle attachment portion; a diaphragm configured to generate negative pressure in the inner passage; a handle manually operated to move back and forth; and a link mechanism configured to support the handle in a manner movable back and forth relative to the body. The handle is configured to change pressure of the inner passage from a normal state to a negative state by displacing the diaphragm in a lifting direction. The link mechanism is configured to apply an operation force to the handle that becomes maximal during handle movement when the handle is moved in an operation direction that changes the pressure from the normal state to the negative state.

Abstract: A breast pump includes a main body and a handle. The main body includes an internal passage, a negative pressure generation mechanism configured to generate negative pressure in the internal passage for pumping milk, a hood attaching portion to which a hood fitted to a breast is attached, the hood attaching portion being disposed at a front part of the main body, and a bottle attaching portion to which a bottle for collecting milk is attached, the bottle attaching portion being disposed at a lower part of the main body. The handle is pivotal to the main body and includes a basal end, at a side located closer to a pivot point on the main body, connected to the negative pressure generation mechanism. The handle includes a finger rest at a distal side and extends forward from the pivot point beside the main body.
