Abstract: The invention relates to a nasal applicator (2) having a channel (3) which opens at: an opening (4) at a first end (5) of the applicator, which is intended to be inserted into a person's nose; and an opening (6) at a second end (7) of the applicator, which is provided with means (27, 28, 30) for securing same in an opening in the body of a nasal fluid aspiration device in a removable, sealed manner. The opening (6) at the second end is sealed by a non-porous element (8) which can deform elastically when a vacuum is created by a vacuum source in the body of the aspiration device and which is intended to form a nasal fluid container. The nasal applicator includes non-return means (9, 13) which prevent the nasal applicator from being emptied when a vacuum is no longer being applied to the deformable element. The elastically-deformable nasal applicator and the non-return means can deform when pressure is exerted on the nasal applicator so that the applicator and the container can be emptied.

Abstract: The invention relates to a nasal secretion aspiration device. The inventive device consists of: a hollow body (3) which defines a vacuum chamber (9) that can be connected to a vacuum source (10), said chamber (9) comprising an opening (13); and a nasal end piece (2) comprising a first open end (5) which is designed to be inserted into a person's nose and a second open end (7) which is equipped with means for fixing same in a leak-tight, removable manner in the opening (13) of the hollow body (3). According to the invention, the second end (7) is sealed by a non-porous deformable element (8) under a vacuum created in the vacuum chamber (9) by the vacuum source (10).
