Abstract
The present invention relates to a biological sample self-collection device that houses a collector (such as a “veil”, buffer, swab, brush, etc.) for any biological material, preferably of vaginal origin. At the same time, it is designed to combine a reactive liquid with said substances for subsequent analysis thereof in a watertight manner. Its use includes the detection of pathogens, such as human papillomavirus, and the diagnosis of cervical cancer, among others.
Claims4
A device for the collection and/or transport of isolated biological samples from a human subject, designed to house a biological sample collector (15), comprising:
- a container (1) with an open lower tubular body (2) intended to house the biological sample collector (15) and an upper head (3) with an internal thread (4);
- and
- a cap (5) with an upper section (6) incorporating an external thread (7), the cap (5) being intended to be screwed onto the internal thread (4) of the upper head (3) of the container (1),
- wherein the cap (5) additionally comprises a tubular portion (8) extending downward from the upper section (6) and ending in a filter (9), and an annular reservoir (10) located in the upper section (6) around the tubular portion (8) that contains a reactive liquid (11), the annular reservoir (10) being sealed at the bottom by a breakable lower sheet (12),
- wherein the tubular body (2) is equipped with barbs (13) extending upward such that when the cap (5) is screwed onto the upper head (3) of the container (1), these barbs (13) break the lower sheet (12), allowing the reactive liquid (11) to flow into the tubular body (2) and come into contact with the biological substances collected by the sample collector (15), reacting with them,
- wherein the volume of fluid in the annular reservoir (10) and the height of the tubular portion (8) being such that the reactive liquid (11) combined with the biological substances is partially introduced through the tubular portion (8) via the filter (9),
- wherein the cap further comprises an additional breakable upper sheet (14) that closes off the tubular portion (11) and is designed to facilitate the insertion of a pipette (16) through the tubular portion (8) to reach the previously ascended reactive liquid (11) and wherein the device further includes immobilisation means (17) that secure the cap (5) once it is fitted onto the container (1), thus preventing manipulation and contamination of the collected sample.
