Systems, devices, and methods for sample collection
Provided herein are systems, devices, and methods for sample collection. A sample collection device may comprise a vessel, a lid, and pre-loaded liquid solutions. The sample collection device may collect a liquid sample, such as a biological sample. The liquid solutions may comprise reagents for preserving and/or stabilizing biological samples, such as saliva, collected in the vessel. A chamber comprising the liquid solutions may be located in the vessel and/or the lid. In some instances, the liquid solution may be released from the chamber upon closure of the vessel with the lid. In some instances, the liquid solution may be released from the chamber upon actuation of an implement, such as a plunger. In some instances, the liquid solution may be released upon compression of an absorbent member. The sample collecting device may be delivered to a remote location for further processing and/or analysis.
1. A device removably engageable with a funnel and, alternatively, with a lid, the device comprising:
an outer wall defining a device opening of the device, wherein the outer wall is configured to be engageable with the funnel for the device to receive a DNA sample that is funneled through the device opening and wherein the outer wall is further configured to be engageable with the lid to close the device opening;
a first chamber defined by the outer wall;
an inner wall defining an implement; and
a second chamber included in the implement, wherein the inner wall shares the device opening with the outer wall and further comprises a wall opening for fluid communication between the first chamber and the second chamber, wherein one of the first and second chambers is configured to receive the DNA sample and another of the first and second chambers is configured to store a liquid solution; and
wherein the inner wall is movable relative to the outer wall so that the implement is movable between a first configuration and a second configuration, wherein the implement in the first configuration closes the wall opening and the implement in the second configuration opens the wall opening for the fluid communication; and wherein the implement is configured to be in the first configuration when the outer wall is engaged with the funnel and configured to be in the second configuration responsive to the lid pushing the implement towards the second configuration, thereby opening the wall opening.
2. The device of claim 1 , wherein the device is configured to be engaged with the lid by complementary threading, form-fitting pairs, interference fitting, hooks and loops, latches, screws, staples, clips, clamps, prongs, rings, brads, rubber bands, rivets, grommets, pins, ties, snaps, adhesives, tapes, vacuum, seals, or any combination thereof.
3. The device of claim 1 , wherein the first and second chambers are configured to be sealed from an outside environment at the device opening by the lid when the lid is engaged with the device.
4. The device of claim 3 , wherein the sealing is fluid-tight.
5. The device of claim 1 , wherein the DNA sample is a biological sample selected from saliva, sputum, spit, blood, perspiratory fluid, sweat, pus, a tear, mucosal excretion, vomit, urine, a stool, semen, vaginal fluids, a cell-free sample, a cheek swab, a swab of a different bodily part, a homogenous sample, a heterogeneous sample, a tumor sample, plasma, or a serum sample.
6. The device of claim 1 , wherein the liquid solution is a reagent or a DNA stabilization solution.
7. The device of claim 1 , wherein the liquid solution comprises reagents that preserve and/or stabilize the DNA sample.
8. The device of claim 1 , wherein the first chamber and the second chamber are vertically neighboring compartments, horizontally neighboring compartments, diagonally neighboring compartments, or placed relative to the other in another orientation.
9. The device of claim 1 , wherein the device is dimensioned to fit inside a container for shipping the device.
10. A system comprising:
a lid;
a funnel; and
a sample collection device removably engageable with the funnel and, alternatively, with the lid, the sample collection device comprising:
an outer wall defining a device opening of the device, wherein the outer wall is configured to be engageable with the funnel for the device to receive a DNA sample that is funneled through the device opening and wherein the outer wall is further configured to be engageable with the lid to close the device opening;
a first chamber defined by the outer wall;
an inner wall defining an implement; and
a second chamber included in the implement, wherein the inner wall shares the device opening with the outer wall and further comprises a wall opening for fluid communication between the first chamber and the second chamber, wherein one of the first and second chambers is configured to receive the DNA sample and another of the first and second chambers is configured to store a liquid solution; and
wherein the inner wall is movable relative to the outer wall so that the implement is movable between a first configuration and a second configuration, wherein the implement in the first configuration closes the wall opening and the implement in the second configuration opens the wall opening for the fluid communication; and wherein the implement is configured to be in the first configuration when the outer wall is engaged with the funnel and configured to be in the second configuration responsive to the lid pushing the implement towards the second configuration, thereby opening the wall opening.
