A Breast Pump (搾乳器, Sakunyū-ki) is a device designed to manually extract milk from a lactating breast by using suction to pull the breast nipple into a flange, and then release, in similar motion to suckling. Most breast pumps also possess a container to deposit the expressed milk.
The use of a breast pump can be for a variety of reasons. Many women use breast pumps to bottle feed their child. A breast pump may also be used to stimulate lactation for women with a low milk supply or those who have not just given birth. A breast pump may also be used to relieve breast engorgement, a painful condition whereby the breasts are overfull and must be emptied.
- While it can be used as an alternative, the breast pump is not as efficient at removing milk from the breast as most nursing babies.
