Abstract

Sample processing methods and systems to collect a biological sample. A device may be configured collect a predetermined volume of a sample in sample chamber, and seal the chamber upon activation. The device may be further configured to mix the mix the sample with a predetermined volume of a reagent and/or mix the sample and the reagent in a pre-determined ration.

Claims (39)

1. A device for collecting a biological sample comprising:

a housing comprising a collection well configured to receive a biological sample;

a conduit, disposed within the housing, wherein the conduit comprises a capillary tube comprising openings at a first end and a second end, with the opening at the first end receiving the biological sample from the collection well and thereby drawing the biological sample from the collection well into the conduit via capillary action;

a sample storage chamber, disposed within the housing, and arranged to receive the biological sample from the conduit;

the housing further configurable in a first position and a second position, whereby the first position provides an opening to the collection well, and the second position restricts access to the collection well; and

a mechanical actuator, configured to dispense a predetermined amount of the biological sample from the second end of the conduit into the sample storage chamber when the housing is moved from the first position to the second position,

wherein the sample storage chamber includes a membrane.

2. The device of claim 1 , wherein the sample storage chamber holds a reagent.

3. The device of claim 1 , wherein:

the housing is formed from first and second portions configured to be pressed towards one another, to configure the device from the first position to the second position.

4. The device of claim 3 wherein the first and second portions of the housing are locked in position when the device is moved to the second position.

5. The device of claim 1 , wherein the mechanical actuator is rotatable.

6. The device of claim 1 , wherein the sample storage chamber further comprises a drying medium that dries the biological sample.

7. The device of claim 1 , wherein the membrane further comprises a test region, the test region disposed within the housing and configured for testing the biological sample.

8. The device of claim 7 , wherein the test region is in fluid communication with the conduit.

9. The device of claim 8 , wherein the test region is in fluid communication with the conduit and the sample storage chamber via a fluid passage region.

10. The device of claim 7 , wherein the test region comprises a lateral flow strip.

11. The device of claim 1 , further comprising a reagent chamber, disposed within the housing, the reagent chamber holding a liquid reagent, wherein the mechanical actuator, dispenses a predetermined amount of the liquid reagent from the reagent chamber via mechanical force when the housing is moved from the first position to the second position.

12. The device of claim 11 , further comprising a plunger, controlled by the mechanical actuator, to move the reagent from the reagent chamber through a fluid outlet of the reagent chamber.

13. A device for collecting a biological sample comprising:

a housing comprising a collection well configured to receive a biological sample;

a conduit, disposed within the housing, wherein the conduit comprises a capillary tube comprising openings at a first end and a second end, with the opening at the first end receiving the biological sample from the collection well and thereby drawing the biological sample from the collection well into the conduit via capillary action;

a sample storage chamber, disposed within the housing, and arranged to receive the biological sample from the conduit;

the housing further configurable in a first position and a second position, whereby the first position provides an opening to the collection well, and the second position restricts access to the collection well; and

a mechanical actuator, configured to dispense a predetermined amount of the biological sample from the second end of the conduit into the sample storage chamber when the housing is moved from the first position to the second position,

the device further comprising a test region disposed within the housing and configured for testing the biological sample.

14. The device of claim 13 , wherein the sample storage chamber comprises a reagent.

15. The device of claim 13 , further comprising a wicking material disposed within the fluid passage region so as to wick a fluid comprising the biological sample to the test region.

16. A device for collecting a biological sample comprising:

a housing comprising a collection well configured to receive a biological sample;

a conduit, disposed within the housing, wherein the conduit comprises a capillary tube comprising openings at a first end and a second end, with the opening at the first end receiving the biological sample from the collection well and thereby drawing the biological sample from the collection well into the conduit via capillary action;

a sample storage chamber, disposed within the housing, and arranged to receive the biological sample from the conduit;

the housing further configurable in a first position and a second position, whereby the first position provides an opening to the collection well, and the second position restricts access to the collection well; and

a mechanical actuator, configured to dispense a predetermined amount of the biological sample from the second end of the conduit into the sample storage chamber when the housing is moved from the first position to the second position,

wherein the housing is formed from first and second portions configured to be pressed towards one another, to configure the device from the first position to the second position, and

wherein the first and second portions of the housing are locked in position when the device is moved to the second position.

17. The device of claim 16 , wherein the sample storage chamber comprises a reagent.

18. The device of claim 16 , wherein the sample storage chamber comprises a membrane.

19. The device of claim 16 , the device further comprising a test region disposed within the housing and configured for testing the biological sample.
