Rapid test device

Abstract

The invention discloses a rapid test device, includes a cup vessel (), which comprises a first chamber () and a dosing piston assembling hole () communicating with the first chamber (); a base () fastened at the bottom of the cup vessel (); a second chamber (), formed between the base () and the cup vessel () and communicating with the dosing piston assembling hole (); a partition (), arranged in the second chamber () and provided with test paper; a dosing piston (), provided with a dosing slot () thereon and provided with a key hole at one end, inserted in the dosing piston assembling hole (); and a key () matching the key hole. In present invention the sample in the dosing slot can be transmitted into the second chamber by rotating the dosing piston. The sample is absorbed by the test paper after flowing by the test paper, and test result appears on the test paper. Since the dosing slot is machined on the dosing piston, the volume of the liquid sample obtained each time is equal and the accuracy of test result is improved. The dosing piston used to obtain the liquid sample is changed from being pushed linearly to being moved rotationally, which makes leak-proof effect better.
