Systems and methods for fluid sample collection and testing
A fluid sample testing apparatus has a fluid collector tube and a fluid collector in fluid communication with a sample holding container. The fluid collector is inserted into and penetrates the fluid collector tube and pressure is generated to release fluid from the fluid collector into the sample holding container, and air passes outside of the apparatus from the fluid collector tube via a vent path. The vent path is sealed with the fluid collector is fully inserted into the fluid collector tube. Indicator or test strips are optionally included in a stem of the fluid collector.
1. A fluid sample testing apparatus comprising:
a housing with a fluid collector tube;
a sample holding container in fluid communication with the fluid collector tube and removably secured to the fluid collector tube;
a fluid collector, wherein the fluid collector has an elongated stem and is adapted for insertion into the fluid collector tube and upon insertion and penetration into the fluid collector tube pressure is generated to release fluid from the fluid collector into the sample holding container;
a gasket positioned in the fluid collector tube having an upper portion engaging a wall of the fluid collector tube and a lower portion of smaller diameter than the upper portion extending into an opening of the sample holding container, wherein the gasket is positioned at an upper location in the fluid collector tube upon insertion of the fluid collector into the fluid collector tube, wherein the gasket is positioned at a lower location in the fluid collector tube after insertion of the fluid collector into the fluid collector tube and at the lower location a surface of the gasket that is positioned between the upper portion and the lower portion engages a top surface of the sample holding container and forms a seal with the sample holding container, wherein air passes outside of the apparatus from the fluid collector tube around an upper portion of the sample holding container before the gasket is positioned at the lower location.
2. The apparatus of claim 1 , wherein the fluid collector has an upper sealing portion such that upon substantially complete insertion and penetration of the fluid collector into the fluid collector tube the upper sealing portion seals the fluid collector tube.
3. The apparatus of claim 2 , wherein the fluid collector has a lower sealing portion adapted to form a sliding seal between the lower sealing portion and a surface wall of the fluid collector tube as the fluid collector is inserted and penetrated into the fluid collector tube.
4. The apparatus of claim 3 , wherein the upper sealing portion forms a stopper seal with an upper surface wall of the fluid collector tube, and the lower sealing portion forms a syringe plunger seal between the lower sealing portion and a lower surface wall of the fluid collector tube.
5. The apparatus of claim 4 , wherein the lower sealing portion is formed to have a plurality of spaced apart o-ring portions to form the syringe plunger seal.
6. The apparatus of claim 4 , wherein the lower sealing portion is formed to have a textured surface to form the syringe plunger seal.
7. The apparatus of claim 1 , wherein the fluid collector includes a swab material at a lower end and a top cap, with the elongated stem extending from proximate to the swab material to proximate to the top cap, wherein the stem has an open cavity containing at least a moisture indication strip that contacts a portion of the swab material and changes color subsequent to contacting fluid absorbed by the swab material.
8. The apparatus of claim 7 , wherein the open cavity of the stem further contains a strip indicating the presence or absence of an analyte or pathogen.
9. The apparatus of claim 7 , wherein the open cavity of the stem also contains at least one analyte or pathogen detection strip that also is in contact with the swab material, wherein the at least one analyte or pathogen detection strip indicates the presence or absence of an analyte or pathogen.
10. The apparatus of claim 1 , wherein the fluid collector includes a swab material at a lower end and a top cap, with the elongated stem extending from proximate to the swab material to proximate to the top cap, wherein the stem has an open cavity containing one or more analyte or pathogen detection strips that are in contact with the swab material, wherein the one or more strips indicate the presence or absence of an analyte or pathogen.
11. The apparatus of claim 10 , wherein the open cavity of the stem contains two analyte or pathogen detection strips that are in contact with the swab material and that are arranged in a back-to-back configuration, wherein each of the two strips indicates the presence or absence of one of a first and a second analyte or pathogen.
12. The apparatus of claim 1 , wherein a vent path is formed between an attachment portion of the fluid collector tube and the sample holding container, wherein air passes outside of the apparatus from the fluid collector tube around the upper portion of the sample holding container through the vent path before the gasket is positioned at the lower location.
13. The apparatus of claim 12 , wherein the attachment portion of the fluid collector tube comprises threads, wherein the sample holding container is removably secured to the fluid collector tube via the threads.
14. The apparatus of claim 1 , wherein the sample holding container contains a buffer for transporting a sample contained in the sample holding container to a laboratory.
15. The apparatus of claim 14 , wherein the buffer comprises a lysis buffer.
16. The apparatus of claim 14 , wherein the buffer comprises an RNA or DNA preservative buffer.
