The present invention provides a nasal suction device, comprising a collection chamber, a resilient bulb, and a one-way valve. The collection chamber includes a main body, a cover, and an inner space, the cover being removably connected to the main body in substantially airtight relation, to define the inner space. The resilient bulb is removably connected to the main body in substantially airtight relation. The cover comprises a first tube extending into the inner space, through which the secretion may be suctioned into the collection chamber. The main body comprises a second tube, an opening of which adjacent to the resilient bulb is configured with the one-way valve.本發明提供一種吸鼻器，其包含一集涕室、一彈性球及一單向閥。該集涕室包括一本體、一蓋體及一內部空間，該蓋體以實質氣密的關係可拆卸地連接至該本體，以界定該內部空間。該彈性球以實質氣密的關係可拆卸地連接至該本體。該蓋體包含一第一管體，延伸至該內部空間，經此分泌物可被吸入該集涕室中。該本體包含一第二管體，其與該彈性球相鄰的開口設有該單向閥。
