Patent ID: 11808672

Abstract:
The invention provides a detection device, comprising a fluid sample collecting chamber, the collecting chamber including an opening, a testing element is arranged in the collecting chamber, and the testing element is used to test the presence of the analyzed substance in the fluid sample; the detection device further comprises a cover body used to close the opening of the collecting chamber; wherein the cover body includes an elastic card used to engage the opening of the collecting chamber, when the cover body closes the opening of the collecting chamber, the elastic card engages the outer wall of the opening of the collecting chamber, thereby fixing the cover body on the collecting chamber. The cover body of the invention is buckled with the collecting chamber, an elastic card and a buckle structure are arranged to facilitate fastening between the cover body and the bottle body, but make it difficult to separate them apart; this can avoid leakage of a sample inside the collecting chamber; a guide structure is arranged in the cover body, so that a closing area is formed when the opening of the collecting chamber is not deliberately aligned with the elastic card in the cover body during using, the closing between the cover body and the collecting chamber can be easily achieved, thereby improving the testing efficiency.
