A breastpump for expressing human breastmilk comprises a housing (8), a pump chamber (47) with a driven pump membrane (7) for producing a vacuum, and a breast shield (2) with an interior (200) for receiving a mother's breast. Expressed milk flows from the interior (200) into the pump chamber (47) through a milk channel, said pump chamber having an outlet opening (480) through which expressed milk flows from the pump chamber (47) into a milk collection container (9). The breastpump comprises a multipart hygiene module (2, 3, 4, 5) comprising a first part (2) with a flow opening (24, 25) for connecting to the interior (200), a valve body (3) with at least one valve (34, 37) and a second part (4) with a rigid cup for forming the pump chamber (47). The valve body (3) is arranged between the first and second part (2, 4) and the hygiene module (2, 3, 4, 5) as a whole is connectable to the housing (8) of the breastpump in a sealing and detachable manner.本發明提供一種用於吸出人類母乳之吸乳器，其包含：外殼(8)；泵室(47)，其具有驅動泵隔膜(7)，該泵室(47)用於產生真空；及乳房護罩(2)，其具有用於收納母親之乳房的內部(200)。吸出之乳汁自該內部(200)經由乳汁通道而流動至該泵室(47)中，該泵室(47)具有出口開口(480)，吸出之乳汁自該泵室(47)經由該出口開口(480)流動至乳汁收集容器(9)中。該吸乳器包含多部分衛生模組(2、3、4、5)，該多部分衛生模組(2、3、4、5)包含：第一部分(2)，其具有用於連接至該內部(200)之流動開口(24、25)；閥體(3)，其具有至少一個閥(34、37)；及第二部分(4)，其具有用於形成該泵室(47)之剛性杯。該閥體(3)係配置於該第一部分(2)與該第二部分(4)之間，且該多部分衛生模組(2、3、4、5)可作為整體以密封且可拆卸方式連接至該吸乳器之該外殼(8)。
