Pear breast pumps

With pear

— in accordance with the name, such breast pumps are equipped with a rubber pear that needs to be compressed and unclenched (similar to how air is pumped into a hand tonometer — only here the pear does not pump air, but draws it out of the nozzle, providing suction). Such devices are quite simple and inexpensive, but not very convenient — at least because when pumping, both hands are occupied by the mother. Also note that the effectiveness of "pear" models is generally low, and the effect on the nipple can be quite rough.
