- the release device 24 is configured to abut against the guide device 18 when the rod 14 moves in the sampling direction A.
- the release device 24 is configured to cooperate with the guiding device 18 by securing the release device 24 to the guiding device 18.
- the lashing is for example made by picking and / or magnetization.
- Stowage of the release device 24 to the guide device 18 advantageously allows the initiation of the traceability device 19.
- the release device 24 When the rod 14 reaches the extraction position, the release device 24 thus connects to the guide device 18 so that a displacement of the release device 24 with the rod 14 causes a displacement of the guide device 18 with the rod 14.
- the release device 24 is further configured to break the fastening device 34 due to the twisting or pressure exerted on the release device 24 by the user via the gripping element 20.
- the torsion or pressure force exerted advantageously allows the initiation of the traceability device 19.
- the guiding device 18 becomes mobile with the rod 14 and no longer forces the rotational movement of the rod 14 when the rod 14 is moved in translation.
- the device 10 is in the first retracted configuration, as illustrated in FIG.
- the brush 16 and the guiding device 18 are located in the interior volume of the sleeve 12.
- the user grasps the gripping element 20 and, by exerting a longitudinal force in the sampling direction A on the gripping element 20, causes a rotation and translation movement of the rod 14, the movement being guided by the device guide 18.
- the rod 14 cooperates with the guiding device 18, the guiding device 18 being fixed to the sleeve 12 by the fixing device 34.
- the rod 14 then moves in translation and in rotation around the axis of the rod 14 in the sampling direction A.
- the brush 16 deviates from the sleeve 12 while rotating, thereby making it possible to take biological elements in the specific zone.
- the device 10 is then in the sampling configuration, illustrated in FIG.
- the release device 24 moves with the rod 14 in the sampling direction A and approaches the guide device 18.
- the distance between the release device 24 and the guide device 18 in the first retracted configuration is such that the rod 14 has made the predetermined minimum number of revolutions, and therefore the brush 16 has completed the sampling, when the release device 24 reaches the guide device 18 in abutment.
- the minimum number of laps to complete is one complete turn.
- the release device 24 cooperates and binds with the guide device 18.
- the user continues to exert a pressing force on the gripping element 20 so that the release device 24 breaks the fixing device 34 and initiates traceability by securing the release device 24 to the guiding device 18.
- the release device 24 thus releases a translation-only movement of the rod 14 in the extraction direction B.
- the device 10 is then in the second retracted configuration.
- the brush 16 is located in the inner volume 26 of the sleeve 12 and the traceability device 19 is located away from the sleeve 12.
- the traceability device 19 initiated by the stowage is then readable by the user or readable by a remote reading device.
- the device 10 thus makes it possible to take a sample of biological elements of good quality. Indeed, a user easily performs the sampling without control of the necessary gesture.
- the predetermined number of turns of the rod 14 and therefore the brush 16 provides a quality sampling and the release device 24 can bring the device 10 easily in the retracted position without redepositing the biological elements taken from the brush 16 because the brush 16 does not rotate in the opposite direction when the rod moves in the extraction direction.
- the traceability device 19 becomes active and readable only in the case of a well-made sampling, that is to say when the brush 16 has made the number of turns necessary to have enough biological elements harvested.
- the user of the device 10 knows when he has made a quality sampling and a diagnosis can not be launched without this sampling of good quality, thus ensuring the quality of the diagnosis made thereafter.
- Such a device 10 is therefore particularly well suited for use by a patient or a non-specialist sampler.
- the device 10 can therefore be used to perform a self-sampling of biological elements during a screening campaign, as will be described later.
- a second sampling device 1 10 biological elements is illustrated in Figure 4.
- the second sampling device 1 10 is similar to the first device 10. Only the differences between the two devices 10, 1 10 are described later.

- the release device 24 carries the traceability device 19.
- the release device 24 comprises an upper end 38 and a lower end 40, "upper” and “lower” being defined along the axis X-X ', the upper end 38 being closer to the brush 16 and the end lower 40 being closer to the gripping element 20.
- the inner surface of the release device 24 is threaded.
- the release device 24 further comprises a pin 42 projecting from the outer surface of the release device 24 substantially orthogonal to the X-X 'axis.
- the release device 24 is fixed to the sleeve 12 by a fixing device 34.
- the outer surface of the release device 24 is in contact with the inner surface of the sleeve 12, the sleeve 12 exerting a frictional force on the attachment device 34.
- the sleeve 12 further comprises a groove 44 defined on the inner surface of the sleeve 12.
- the groove 44 comprises a first portion 46 extending in a plane orthogonal to the axis XX 'and a second portion 48 parallel to the axis XX 'and oriented in the direction of extraction B.
- the first portion 46 extends over an angular sector greater than 30 °, preferably between 30 ° and 180 °.
- the groove 44 is a helicoid around the axis X-X ', on the inner surface of the sleeve 12, and oriented in the extraction direction B.
- the groove 44 is configured to receive the pin 42 and thus to guide the release device 24.
- the sleeve 12 also includes a first window 50 configured to allow a user to see inside the sleeve 12.
- the first window 50 is arranged such that the traceability device 19 is visible to a user when the sampling device 1 10 is in the second retracted configuration.
- the second sampler 1 10 differs from the first sampler 10 also in that the device 18 is integral with the rod 14 permanently.

- the traceability device 19 is readable only after a predetermined number of revolutions made by the rod 14 in the sampling direction A and when the fourth sampling device is in the sampling configuration or in the second retracted configuration.
- the use of the fourth sampling device is similar to the use of the second device 1 10.
- the use of the fourth device differs only in that when the pin 42 comes into abutment at the end of the first portion 46, the traceability device 19 is located opposite the second window.
- the traceability device 19 is then readable by the user by the second window.
