Patent attributes
A manual breast pump includes: a body having a communicating part that communicates with space surrounded by a hood placed on a breast; a diaphragm that deforms to generate a negative pressure in the communicating part; and a handle for operation that approaches and separates from the body, wherein a colliding part, against which at least the handle and the body collide before directly contacting each other, is provided in at least a region of any of the handle, the body, and the diaphragm, the colliding part is integrally made of a same material as a material of a region in which the colliding part is arranged, and has a damper structure that absorbs an impulsive force or reduces propagation of the impulsive force and/or a cover structure in which the colliding part is covered via a gap so as not to be exposed to an outside.
