Abstract

L'invention concerne un dispositif d'aspiration synchronisée (1) qui peut être dissimulé sur le corps d'une femme et un tire-lait facile à transporter pour un usage portatif. Le dispositif d'aspiration synchronisée (1) présente une structure plate et une membrane en forme de disque (12) est disposée dans une cavité correspondante. La membrane en forme de disque (12) est orientée de façon oblique afin de séparer la cavité intérieure en deux espaces cunéiformes dans des directions opposées, l'espace cunéiforme dans la position supérieure étant une chambre à air (15) et l'espace cunéiforme dans la position inférieure étant une chambre d'écoulement de liquide (14). La chambre à air (15) présente une interface de courant d'air (111), la chambre d'écoulement de liquide (14) présente une interface d'entrée de liquide (131) et une interface de sortie de liquide (132). La membrane en forme de disque (12) comporte une valve (141) normalement ouverte sur sa partie centrale. Le tire-lait comporte des bonnets (2), une pompe à air (4) et une poche à lait (3), ainsi que le dispositif d'aspiration synchronisée (1) susmentionné. Un orifice d'air (411) de la pompe à air (4), une sortie de lait (211) des bonnets (2) et une entrée de lait (311) de la poche à lait (3) sont respectivement reliés à l'interface de courant d'air (111), à l'interface d'entrée de liquide (131) et à l'interface de sortie de liquide (132) du dispositif d'aspiration synchronisée (1) au moyen de tuyaux flexibles. Le volume du dispositif d'aspiration synchronisée est petit, ce qui permet de dissimuler facilement ledit dispositif sur le corps, et l'inversion de la membrane en forme de disque (12) permet d'obtenir instantanément une pression négative relativement importante, ce qui répond aux besoins de pompage de lait. Lorsque la membrane est rétablie, la valve (141) s'ouvre, permettant ainsi au lait de s'écouler rapidement dans la poche à lait (3) sous l'effet d'une pression ordinaire.
