The invention relates to a multi-purpose body detector, which comprises a cylinder body with a first scale area and a second scale area, a rod body which is arranged in the cylinder body, a piston which is movably combined with one end of the rod body and is located in the cylinder body, a first cover which is movably combined with one end of the cylinder body, and a second cover which is combined with the piston activity after the rod body is removed.In this way,After the needle is connected at one end of the barrel,Using needles,The matching of the rod body and the piston extracts the inspection body into the cylinder body.After extraction, the needle and the rod are removed.The cylinder body is then sealed with the first and second covers respectively.In order to directly perform the separation action of the follow-up examination body,Then remove the first and second covers.And output the inspection materials needed or not needed by the cylinder body with the rod body.And it can be used for extracting or outputting the body.Use the first and second scale areas to accurately extract or output the appropriate amount.It is easy to operate and use.The utility model can effectively avoid the contamination of the test body and reduce the cost.本創作關於一種多用途檢體採集器，其包含有一具有一第一刻度區及一第二刻度區之筒身；一活動設於筒身中之桿體；一與桿體一端活動結合且位於筒身中之活塞；一活動結合於筒身一端之第一封蓋；以及一於桿體移除後與活塞活動結合之第二封蓋。藉此，可於筒身一端結合針頭後，利用針頭、桿體與活塞之配合將檢體抽取於筒身中，並於抽取後移除針頭與桿體，再分別以第一及第二封蓋將筒身加以封閉，以直接進行後續檢體之離析動作，之後移第一及第二封蓋，並配合桿體將筒身需要或不需要之檢體物質加以輸出，且可於進行抽取或輸出檢體時，利用第一及第二刻度區之配合準確抽取或輸出適當之用量，而達易於操作使用、有效避免檢體遭受污染以及降低成本之功效。
