Milk pump for extraction of milk from breast, has sliding part moved into slot and pulling piston, where vacuum is generated and is moved into funnel to suck milk, and piston exerts force on valve to open valve and to drop milk into bottle

摘要

The pump has a hand grip (19) and an arm (18), where the arm is stretched, and a sliding part is moved into a longitudinal slot and thus pulls a piston (17) after putting a breast plate on a breast and crushing the grip. The vacuum is generated in the part of a cylinder (14) and is moved into a funnel (12) to suck milk from the breast. The milk is dropped via the funnel and a sealing rim for intermediate storage in a closed valve (111). The piston is moved downward and exerts a force on the valve after releasing the grip, where the force opens the valve and the milk is dropped into a bottle.
