Device for detecting an analyte in a sample
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.
1 . A device for detecting an analyte in a fluid sample, comprising:
a chamber for receiving a testing element therein;
a carrier located in the chamber, wherein the carrier is used for bearing the testing element;
a movable element; and
a locking structure;
wherein the movable element is connected with the carrier; the movable element has a first locking position and a second position on the chamber,
wherein, when the movable element is in the first position, the testing element on the carrier is not contact with the fluid sample; when the movable element is in the second position, the testing element is in contact with the fluid sample; after being unlocked, the movable element is capable of manually sliding to the second position from the first position, thus driving the carrier to move to the second position from the first position,
wherein the chamber comprises a sliding groove, the movable element includes a sliding rail, and the movable element is capable of moving from the first position to the second position via the sliding rail sliding in the sliding groove of the chamber,
wherein the movable element is connected with the chamber via the locking structure, and a portion of the locking structure is located on the sliding groove of the chamber, and another portion of the locking structure is located on the movable element, and
wherein the portion of the locking structure located on the sliding groove comprises two opposing notches disposed relatively, and the portion of the locking structure located on the movable element comprises two bolts.
2 . The device according to claim 1 , wherein when the bolts are received by the notches, the movable element is locked in the first position; and when the bolts are separated from the notches, the movable element is capable of moving from the first position to the second position.
3 . The device according to claim 2 , wherein the carrier comprises a receiving opening; the movable element comprises an insertion piece; the insertion piece is inserted into the receiving opening, thus achieving the connection between the carrier and the movable element.
4 . The device according to claim 3 , wherein the sliding rail on the movable element is connected with the insertion piece.
5 . The device according to claim 4 , wherein the sliding rail on the movable element is connected with a positioning piece; the positioning piece is located in the chamber and driven by the sliding rail to slide on the sliding groove.
6 . The device according to claim 5 , wherein the movable element is a sheet structure; and the sliding rail and the positioning piece connected with the sliding rail are disposed at the top of the sheet structure; and the insertion piece is connected below the positioning piece; and the bolts are located at one end of the sheet structure.
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 fluid sample.
8 . The device according to claim 7 , wherein the device further comprises a testing element, and the testing element is located on the carrier.
9 . The device according to claim 8 , wherein the device further comprises an accommodating chamber and a sample collector; the accommodating chamber contains a treating fluid for treating the fluid sample; and the sample collector is fixedly connected with the chamber for receiving the testing element.
10 . The device according to claim 9 , wherein when the carrier is in the second position, the portion of the carrier stretching out of the chamber enters into the accommodating chamber, thus contacting the fluid sample in the accommodating chamber.
11 . The device according to claim 10 , wherein the fluid sample is sample dissolved or lysed by the fluid sample treating fluid collected by the sample collector.
12 . The device according to claim 11 , wherein the fluid sample collected by the sample collector comprises saliva, sputum, urine or nasal secretion.
13 . The device according to claim 12 , wherein the analyte comprises a drug small molecule, a viral antigen fragment or antibody.
