Abstract
Provided is a breast pump for the mother's milk, which makes it possible to obtain universal milk expression data without being affected by an individual difference, for example. The breast pump is composed of a collection container, a milk expressing member, and a negative pressure source for producing pulsated negative pressure. The milk expressing member is provided at an end with a teat cup and at an opposite end with a connector plug to the negative pressure source. The milk expressing member is divided by a partition plate. A flexible teat cup liner is replaceably fitted in the teat cup, and configured to be brought into contact with an areola and nipple of a breast.
Claims7
A breast pump including a collection container, a milk expressing member attachable to said collection container, and a negative pressure source configured to produce a negative pressure such that a pressure is periodically pulsated at constant intervals between said negative pressure and atmospheric pressure;
- said milk expressing member is provided at an end thereof with a teat cup, at an opposite end thereof with a connector plug to said negative pressure source, and between said teat cup and said connector plug with a passageway to said collection container;
- a partition plate is arranged in said passageway to divide said milk expressing member into a space communicated to said teat cup and a space communicated to said connector plug;
- and a teat cup liner is replaceably fitted in said teat cup, wherein said teat cup liner is dimensioned to be brought into contact with an areola and nipple of a breast and has such flexibility and resiliency that said teat cup liner undergoes a deformation toward said teat cup when exposed to said negative pressure but restores to an initial shape thereof when exposed to said atmospheric pressure.
