DEVICE FOR DETECTING AN ANALTE IN A LIQUID SAMPLE

Abstract

The present invention provides a device for detecting an analyte in a sample, including a chamber for receiving a testing element, where the testing element has a first position and a second position in the chamber; the testing element is not in contact with a fluid sample when the testing element is located in the first position, and the testing element is in contact with a fluid sample when the testing element is located in the second position.

Description

Claims

1. A device for detecting an analyte in a sample comprising: a chamber for receiving a testing element, wherein the testing element has a first position and a second position in the chamber;the testing element is not in contact with a fluid sample when the testing element is located in the first position;and the testing element is in contact with a fluid sample when the testing element is located in the second position.

2. The device according to claim 1, wherein the chamber is further connected with a fluid sample collector, and the fluid sample collector is disposed on one end of the chamber.

3. The device according to claim 1, wherein the testing element and the chamber are in a locking state when the testing element is located in the first position.

4. The device according to claim 1, wherein a portion of the testing element stretches out of the chamber when the testing element is located in the second position.

5. The device according to claim 1, wherein the chamber further comprises a carrier used for bearing the testing element; the carrier has a first position and a second position in the chamber; and the carrier drives the testing element to change or move between the first position and the second position, or the carrier drives the testing element to move from the first position to the second position.

6. The device according to claim 5, wherein the carrier is connected to the chamber by a locking structure; the carrier dose not move with respect to the chamber when the carrier is in a locking first position, or, the carrier is capable of moving to the second position from the first position relative to the chamber when the locking structure is unlocked.

7. The device according to claim 6, wherein when the carrier is located in the first position, the whole carrier is completely located in the chamber; when the carrier is located in the second position, a portion of the carrier stretches out of the chamber, thus contacting the liquid sample.

8. The device according to claim 5, wherein the device further comprises a movable element; the movable element is connected with the carrier; and the movable element is capable enabling the carrier to move from the first position to the second position.

9. The device according to claim 8, wherein the movable element comprises a first sliding rail and a second sliding rail; the carrier is fixedly connected with a second sliding rail.

10. The device according to claim 9, wherein the chamber comprises a first sliding groove matched with the first sliding rail of the movable element and a second sliding groove matched with the second sliding rail of the movable element; the second sliding groove penetrates through a side wall of the chamber, and the first sliding groove is located on an outer surface of the chamber.

11. The device according to claim 9, wherein the movable element comprises a portion of the locking structure, and the chamber comprises another portion of the locking structure; the movable element is fixed on the chamber via the locking structure.

12. The device according to claim 9, wherein the carrier comprises a suspending structure, and the carrier is fixedly connected on the second sliding rail via the suspending structure.

13. The device according to claim 11, wherein the locking structure comprises a bulge structure and a notched structure; the movable element comprises the bulge structure; and an outer wall of the chamber comprises a notched structure.

14. The device according to claim 13, wherein the notched structure is located at a sheet structure on a side wall of the chamber; the sheet structure is a portion of the side wall of the chamber; meanwhile, the sheet structure is elastic.

15. The device according to claim 8, wherein the movable element is sleeved on an outer surface of the chamber, and the carrier and the second sliding rail are located in the chamber for receiving the testing element; the first sliding rail is located on the outer surface of the chamber and matched with the first sliding groove on the surface of the chamber.

16. The device according to claim 15, wherein the chamber comprises a limiting structure; the limiting structure comprises an edge; the carrier is a curved surface structure; a concave surface of the carrier is in contact with the edge of the limiting structure, wherein the carrier comprises a backbone structure.

17. The device according to claim 16, wherein the chamber for receiving the testing element comprises a first chamber side wall and a second chamber side wall, wherein the first chamber side wall faces the concave surface of the carrier, and the second chamber side wall faces the backbone structure.

18. The device according to claim 2, wherein the device further comprises an accommodating device; the accommodating device is used for accommodating the collector and a portion of the testing element.

19. The device according to claim 18, wherein the portion of the testing element comprises a portion of a sample application area.

20. The device according to claim 1, wherein the sample is one of saliva, sputum, urine and nasal secretion; and the analyte comprises corona virus.
