Abstract
A sample collection device 100 comprising an elongated sleeve-shaped body 110, and a biased spring 130 arranged within the sleeve shaped body 110. An elongated piston unit 120 having a front end 121 with a sample collection member 121a, and a rear end 122 with a first shoulder 122a. The piston 120 further comprises a sealed chamber 125 arranged within the elongated piston 120 and arranged for holding a reagent. Wherein the piston unit 120 is movably arranged between three positions within the elongated sleeve shaped body 110.In use, pushing the first shoulder 122a of the piston 120 towards the sleeveshaped body 110 biases the spring 130 and exposes the front end 121 of the piston 120, allowing collection of the test sample. Releasing the piston 120 and twisting the shoulder 121a returns the piston 120 into the sleeve-shaped body 110 and breaks the chamber 125 seal, releasing the reagent from the chamber 125 into the sleeve shaped body 110.
Claims (8)
1. Sample collection device (100) comprising: an elongated sleeve-shaped body (110) extending along an axis A, 5 having a first end (111) and a second end (112); body; a biased spring assembly (130) arranged within the sleeve shaped an elongated piston unit (120) comprising: a front end (121) having a sample collection member (121a), a rear end (122) having a first shoulder (122a) having a diameter equal to or larger than the diameter of the sleeve shaped body (110), a second shoulder (123) arranged between the first end (111) and second end (112) and having a diameter smaller than the diameter of the sleeve shaped body (110), a sealed chamber (125) arranged within the elongated piston (120) and arranged for holding a reagent; wherein the piston unit (120) is movably arranged between three positions within the elongated sleeve shaped body (110): a resting position wherein the front end (121) of the elongated piston unit is arranged within the first end (1 1 1) of the elongated sleeve- shaped body and the rear end (122) of the piston is extending out of the second end (1 12) of the elongated sleeve shaped body, and the second shoulder (123) is engaged with the biased spring (130), a sample collecting position wherein the rear end (122) of the piston is pushed towards the second end (112) of the sleeve-shaped body, further biasing the spring, and extending and exposing the front end (111) of the piston from the front end (112) of the sleeve shaped body (110); an analysis position wherein the first shoulder (122a) is rotated at least partly around the axis A, the chamber seal (125a) is broken, wherein the chamber (125) is in fluid connection with the interior of the sleeve-shaped body(1 10).
2. Sample collection device (100) according to claim 1, further comprising a cap arranged for essentially hermetically sealing the front end (111) ofthe sleeve-shaped body (110).
3. Sample collection device (100) according to any previous claim, wherein the spring (130) is arranged to apply pressure on the second shoulder (123) such that at least a portion (124) of the piston (120) penetrates the chamber (125) if the chamber seal (125a) is broken.
4. Sample collection device (100) according to any previous claim, wherein the sample collection member (121a) comprises a fluid absorbing material.
5. Sample collection device (100) according to any previous claim, wherein when the piston (120) is in the analysis position, at least a portion (124) of the piston (120) and the second end (112) of the sleeve-shaped body (110) forms an essentially hermetical seal.
6. Sample collection device (100) according to any previous claim, wherein the spring (130) is a helical spring.
7. Method for use of a sample collection device (100) according to claim 1, comprising the steps of: a. arranging the sample collection device (100) adjacent the sample to be collected; b. pushing the first shoulder (122a) of the piston (120) towards the second end (112) of the sleeve-shaped body (110), biasing the spring (130) and exposing the front end (121) of the piston (120) through the first end (111) of the sleeve-shaped body (110); c. releasing the first shoulder (122a), wherein the biased spring (130) returns the piston (120) to its initial position, the front end (121) of thepiston (120) is arranged inside the first end (111) of the sleeve-shaped body (110); d. twisting the first shoulder (122a), breaking the seal of the chamber (125), allowing the spring (130) to move at least a portion (124) ofthe piston (120) into the chamber (125), and allowing the reagent to flow from the chamber (125) into the sleeve-shaped body (110) towards the front end (121) of the piston (120).
8. Method according to claim 7, wherein step c further comprises covering the first end (1 1 1 ) of the sleeve-shaped body (110), after releasing the first shoulder (122a).
