Abstract

A biological sample collection system and dispensing system is described. The biological sample collection system provides for collection and processing of a biological sample (i.e. bodily fluids collected from nose, throat, or other mucosal membrane of an animal or human). The biological sample collection system includes a sample collector and a collection tube. The sample collector provides a structure for sealing the biological sample in the collection tube for further processing without opening the collection tube, and may provide a structure for collecting the biological sample. When the sample collector and collection tube are removably attached the dispensing system is formed. The dispensing system provides for further processing of the biological sample without opening the collection tube (i.e. without un-securing or removing the plug from the collection tube). The dispensing system further provides dispensing of the processed biological sample without opening the collection tube).

a plug for sealing a collection tube, the plug comprising

an attaching mechanism for removably attaching the plug to the collection tube, the attaching mechanism being below a ridge;

the ridge having a diameter larger than a body of the plug and generally in a center of the plug; and

a dispensing orifice for dispensing a controlled volume of liquid from the collection tube, the dispensing orifice extending through the plug and being cavitated;

a collection end, the collection end being attached to a bottom of the plug, wherein the collection end includes a swab for collecting the biological sample;

a handle, the handle being attached to a top of a cap, wherein the handle includes a break point for removing the handle; and

the cap, the cap removably attached to the plug via a cap securing mechanism, the cap having a first orifice for dispensing the controlled volume of liquid when aligned with the dispensing orifice when the cap is in a dispensing position on the plug, wherein

the attaching mechanism of the plug further being above the ridge, where the cap securing mechanism is complimentary to the attaching mechanism.

2 . The sample collector of claim 1 , wherein

the plug further comprises a delivery orifice for delivering liquid into the collection tube,

the delivery orifice extending through the plug adjacent to the dispensing orifice.

3 . The sample collector of claim 2 , wherein

the cap further comprises a second orifice for delivering liquid when aligned with the delivery orifice when the cap is in a delivery position on the plug, wherein

the second orifice is staggered from the first orifice, where when the cap is in the delivery position, the first orifice is not aligned with the dispensing orifice and is not in the dispensing position.

4 . The sample collector of claim 1 , further comprising

the collection tube configured to receive the collection end and the plug, the collection tube comprising

a flexible tube configured for holding liquid, where the flexible tube is a flexible plastic material;

a receiving portion that is a material less flexible than the flexible tube, the receiving portion configured for receiving the plug via a receiving mechanism, wherein

the receiving mechanism is complimentary to the attaching mechanism being below the ridge of the plug.

5 . The sample collector of claim 4 , wherein

the collection tube is from 30 to 60 millimeters in height and from 5 to 12 millimeters in outer diameter.

6 . The sample collector of claim 4 , wherein

the attaching mechanism is selected from the group consisting of threads, a receiving portion of a snap, or a groove and lock mechanism and combinations thereof.

7 . A biological sample collecting system for containing a biological sample, the biological sample collecting system comprising:

a plug for sealing a collection tube, the plug comprising

an attaching mechanism for removably attaching the plug to the collection tube, the attaching mechanism being below a ridge;

the ridge having a diameter larger than a body of the plug and generally in a center of the plug; and

a dispensing orifice for dispensing a controlled volume of liquid from the collection tube, the dispensing orifice extending through the plug and being cavitated;

a handle, the handle being attached to a top of a cap, wherein the handle includes a break point for removing the handle;

a collection tube configured to receive the plug, the collection tube comprising

a flexible tube configured for holding liquid that is a flexible plastic material;

a receiving portion that is a material less flexible than the flexible tube, the receiving portion configured for receiving the plug via a receiving mechanism, wherein

the receiving mechanism is complimentary to the attaching mechanism being below the ridge; and

the cap, the cap removably attached to the plug via a cap securing mechanism, the cap having a first orifice for dispensing the controlled volume of liquid when aligned with the dispensing orifice when the cap is in a dispensing position on the plug, wherein

the attaching mechanism of the plug further being above the ridge, where the cap securing mechanism is complimentary to the attaching mechanism.

8 . A biological sample dispensing system for dispensing a biological sample, the biological sample dispensing system comprising:

a plug for sealing a collection tube, the plug comprising

an attaching mechanism for removably attaching the plug to the collection tube, the attaching mechanism being below a ridge;

the ridge having a diameter larger than a body of the plug and generally in a center of the plug; and

a dispensing orifice for dispensing a controlled volume of liquid from the collection tube, the dispensing orifice extending through the plug and being cavitated;

a collection end, the collection end being attached to a bottom of the plug, wherein the collection end includes a swab for collection of the biological sample;

the collection tube removably attached to the plug, the collection tube comprising

a flexible tube configured for holding liquid, the flexible tube is a flexible plastic material;

a receiving portion that is a material less flexible than the flexible tube, the receiving portion configured to receive the plug via a receiving mechanism, wherein

the receiving mechanism is complimentary to the attaching mechanism being below the ridge of the plug; and

a cap, the cap removably attached to the plug via a cap securing mechanism, the cap having a first orifice for dispensing the controlled volume of liquid when aligned with the dispensing orifice when the cap is in a dispensing position on the plug, wherein

the attaching mechanism of the plug further being above the ridge, where the cap securing mechanism is complimentary to the attaching mechanism.

9 . The system of claim 8 , wherein

the plug further comprises a delivery orifice for delivering liquid into the collection tube,

the delivery orifice extending through the plug adjacent to the dispensing orifice.

10 . The system of claim 9 , wherein

the cap further comprises a second orifice for delivering liquid when aligned with the delivery orifice when the cap is in a delivery position on the plug, wherein

the second orifice is staggered from the first orifice, where when the cap is in the delivery position, the first orifice is not aligned with the dispensing orifice and is not in the dispensing position.

11 . The system of claim 8 further comprising

a dispensing attachment configured for dispensing liquid from the collection tube with accuracy, the dispensing attachment in removable attachment to the plug via a dispensing attachment securing mechanism, wherein

the attaching mechanism of the plug further being above the ridge, where the dispensing attachment securing mechanism is complimentary to the attaching mechanism.

12 . A method for collecting and processing a biological sample with a biological sample collector and dispensing system, the method comprising:

collecting the biological sample using a sample collector, the sample collector comprising

a plug for sealing a collection tube, the plug comprising

an attaching mechanism configured to removably attach the plug to the collection tube, the attaching mechanism being below a ridge;
