  • Patent number: 12232937
    Abstract: The present invention relates to a swab applicator (1) for use with a sampling cloth (4) comprising a swab rod (2) and an elongated swab head (3) disposed at an end of the swab rod (2) and the swab rod and head are connected to one another at a breakable section (5) which comprises two connection walls (6) formed integrally with the swab rod (2) and head (3) and a through hole (7) extending transversally on the central longitudinal axis of the breakable section (5) and delimited by the connection walls (6), wherein each of the connection walls (6) has two lateral side faces that taper in the proximity of the breakable section (5) towards its central transverse axis resulting in a pre-determined minimum length and thickness of each of the two connection walls (6) proximally to the central transverse axis of the breakable section (5) such that the two connection walls (6) are strong enough to hold the swab rod (2) and swab head (3) together during normal use of the applicator (1) and breakable upon application

  • Patent number: 12207804
    Abstract: The present invention relates to a collecting device (1) for sampling at least one specimen from bodily cavities of humans and animals, comprising: —an elongated flattened pouch (20) having: an open end (200), a top side (201) opposed to the open end (200), situated at a proximal end (101) of the collecting device (1), and two lateral sides (202, 204); and—two creasing means (32, 34), each having a fixed end (301), which is fixed inside the pouch (20) at or in the vicinity of said top side (201) and a free end (303), which protrudes freely through said open end (200), configured such that upon pulling the free ends (303) of the two creasing means (32, 34) in opposite directions, the short side (201) of the pouch (20) is brought closer to the open end (200) while the pouch (20) adopts a creased shape (22).

  • Publication number: 20240407768
    Abstract: The present invention relates to a sampling. flexible cloth (4) with rupture zone which can protect the sampled cells and which is a low-absorbent cloth made of a fabric with an absorbancy of 3.5 g/g or less. having a distal end (4.1) and a proximal end (4.2) defining an insertion direction (x) inside a bodily cavity by means of a swab applicator. the cloth (4) further comprising at least one rupture zone positioned between an upper zone and a lower zone of the cloth (4). the upper zone extends from the proximal end (4.2) towards the rupture zone and the lower zone extends from the rupture zone towards the distal end (4.1) in an opposite direction of insertion (x) wherein the sampling cloth (4) is configured to rupture on at least one rupture zone upon exertion of a tearing force (T) onto the distal end (4.1). when the proximal end (4.2) is maintained in a fixed position relative to the distal end (4.1). thus separating the upper zone from the lower zone.

  • Patent number: 12121422
    Abstract: The invention refers to a swab kit for sampling specimens from humans or animals, comprising a swab applicator (1) comprising a swab rod (2) having an extremity (E) and a sampling cloth (4) made of a low-absorbent flexible fabric, wherein the sampling cloth (4) is fixed to and wound, preferably in a spiral, in overlapping turns (T) around the swab rod (2), over a swab rod end region neighboring the extremity (E), in such a manner that at least an edge portion of the sampling cloth (4) overtops the extremity (E) by at least 1 mm when measured in a longitudinal direction of the swab rod (2).
