Detection device
View Patent ↗A detection device and a detection method are disclosed. The detection device comprises a sample inlet ( 132 ) that allows liquid samples flowing from a collection chamber ( 20 ) to a detection chamber ( 10 ), which comprises a through hole ( 135 ) that allows gases circulation between the detection chamber and the collection chamber, and a sheath ( 140 ) that prevents liquid samples from entering into the detection chamber from the collection chamber via the through hole. The detection chamber contains test reagent strips ( 120 ) to detect whether samples contain interested analytes. The detection device further comprises a protrusion ( 131 ) that enables the detection device standing tilted in the traverse direction. The detection method comprises collecting liquid samples as the first step, followed by standing the device tilted in its traverse direction through a protrusion support, and detecting whether samples contain the analytes.
1. A detection device, comprising a sample inlet that allows passing of liquid from a collection chamber to a detection chamber, wherein the detection chamber further comprises a through hole enabling circulation of gas between the detection chamber and the collection chamber, and a sheath for preventing liquid from entering into the detection chamber from the collection chamber via the through hole;
wherein the detection device comprises a cup lid, and the detection chamber is within the cup lid, while the sheath is on the underside of the cup lid covering the through hole; and
wherein the sheath is tubular.
2. A detection device according to claim 1 , wherein the through hole is positioned higher than where the sample inlet is positioned.
3. A detection device according to claim 2 , wherein the through hole allows passing through of gas but not liquid.
4. A detection device according to claim 1 , wherein the sheath comprises an opening for allowing circulation of gas in the sheath and the collection chamber.
5. A detection device according to claim 4 , wherein the sheath has an opening located at a position higher than that of the through hole.
6. A detection device according to claim 2 , wherein the through hole allows liquid passing through.
7. A detection device according to claim 6 , wherein the sheath has an opening end located at a position higher than that of the through hole.
8. A detection device according to claim 1 , wherein the through hole is located at a position lower than that of the sample inlet.
9. A detection device according to claim 8 , wherein the through hole allows passing through of gas but not liquid.
10. A detection device according to claim 9 , wherein the sheath has an opening end located at a position higher than that of the through hole.
11. A detection device according to claim 1 , wherein the detection device further comprises a protrusion enabling the detection device standing tilted in the traverse direction.
12. A detection device according to claim 2 , wherein the detection device further comprises a protrusion enabling the detection device standing tilted in the traverse direction.
13. A detection device, comprising a cup lid having a detection chamber, the cup lid comprises a sample inlet that allows passing of liquid from the collection chamber into the detection chamber, wherein the cup lid further comprises a through hole enabling circulation of gas between the detection chamber and the collection chamber, a sheath on the underside of the cup lid covering the through hole for preventing the liquid from entering into the detection chamber from the collection chamber via the through hole; and wherein the edge of the sheath is sealindy connected with the cup lid.
14. A detection device according to claim 13 , wherein the through hole is located at a position higher than that of the sample inlet.
15. A detection device according to claim 14 , wherein the through hole allows passing through of gas but not liquid.
16. A detection device according to claim 15 , wherein the sheath comprises an opening for allowing circulation of gas in the sheath and the collection chamber.
17. A detection device, comprising a cup lid having a detection chamber and a test reagent strip, and a cup body having a collection chamber, wherein the cup lid comprises a sample inlet that allows passing of liquid from the collection chamber into the detection chamber, and further comprises a through hole enabling circulation of gas between the detection chamber and the collection chamber, and a sheath on the underside of the cup lid covering the through hole for preventing the liquid from entering into the detection chamber from the collection chamber via the through hole.
18. A detection device according to claim 17 , wherein the through hole is located at a position higher than that of the sample inlet, and the sheath comprises an opening for allowing circulation of gas in the sheath and the collection chamber.
