1. A sample collection and detection method for a sample collection and detection device, wherein the sample collection and detection device includes a collection cavity, an extrusion cylinder located in the collection cavity, a test element and a sample collector; the test element is in liquid communication with the collection cavity; the sample collector includes a collection rod and an absorption element, and the absorption element is provided with a hollow cavity; a part of the collection rod is accommodated in the hollow cavity of the absorption element; a first lug for blocking and locating the absorption element is arranged on the collection rod; the sample collector further includes a gasket having a through hole, and the collection rod passes through the through hole to connect the gasket to one end of the collection rod; the absorption element is located between the gasket and the first lug; a cylinder opening of the extrusion cylinder is provided with a cylinder opening platform; an inner diameter of the extrusion cylinder is greater than or equal to a diameter of the collection rod and is less than a diameter of the gasket; wherein the sample collection and detection method comprising following steps:
collecting a sample by using the sample collector to fill the absorption element of the sample collector with liquid sample;
inserting the sample collector filled with the liquid sample into the extrusion cylinder in the collection cavity, so that the sample flows into the collection cavity;
firstly locating the absorption element on the sample collector directly above the cylinder opening of the extrusion cylinder;
then causing the sample collector to continue to move in a direction of insertion into the extrusion cylinder, causing the collection rod located in the hollow cavity of the absorption element to enter the extrusion cylinder, blocking the gasket at a bottom portion of the absorption element via the cylinder opening platform of the extrusion cylinder, compressing the absorption element after extruding the same via the cylinder opening platform and the gasket, flowing, by the liquid sample, onto the cylinder opening platform and a side wall of the extrusion cylinder after being extruded out from the absorption element, and flowing, by the liquid sample, into the collection cavity;
causing the liquid sample in the collection cavity to flow into the test element for detection; and
reading a detection result on the test element.
