Milk suction system

A milk extraction system includes a body for placement on a nipple of a user, where the body includes a first section and a second section, the first section being configured to form a milk extraction chamber over the nipple and the second section forming a pressure reduction chamber. The volume of the pressure reduction chamber may be reduced by manually deforming the second section, resulting in reduced pressure within the pressure reduction chamber. By using a one-way valve, the pressure in the pressure reduction chamber is substantially balanced with the milk extraction chamber, and re-pumping is also enabled, so that the milk extraction chamber can be re-pressurized by a series of pumping operations. 一种乳汁吸取系统，包括用于放置在用户的乳头上的本体，其中本体包括第一部段和第二部段，该第一部段被配置为在乳头上方形成乳汁吸取室以及该第二部段形成压力减小室。压力减小室的体积可以通过手动地使第二部段变形来被减少，从而引起压力减小室内的减小的压力。通过使用单向阀，压力减小室中的压力与乳汁吸取室基本上得到平衡，并且还能够进行再次泵送，使得乳汁吸取室能够通过一系列泵送操作而被再次加压。
