The present invention relates to a finger tube tourniquet with magnet fasteners for blood collection, and more specifically, to the finger tube tourniquet with the magnet fasteners for blood collection which fixes an elastic rubber tube for tightening a finger by using magnetic force of the magnet fasteners connected to the both ends of the elastic rubber tube while collecting blood from a fingertip to check a physical condition and various diseases. The magnet fasteners keep the elastic rubber tube tight to not be loosened while collecting the blood and allowing a sufficient amount of blood to be collected conveniently and easily. The finger tube tourniquet with the magnet fasteners for blood collection of the present invention includes an elastic rubber tube which is put around and pressurizes a fingertip for collecting blood and a couple of magnet fasteners which are connected to both ends of the elastic rubber tube and fix the both ends of the elastic rubber tube. The couple of magnet fasteners include a center hole which is slightly larger than the diameter of the elastic rubber tube. The magnet fasteners are inserted and fastened to both ends of the elastic rubber tube by a magnet fastening means so opposite poles face each other. The magnet fastening means includes an extension pin which has a large diameter part for enlarging the diameter of both ends of the elastic rubber band by being inserted in through-holes on both ends of the elastic rubber band and a small diameter part for guiding the insertion, and a fixing plate which is inserted to be hung on a protrusion of the elastic rubber tube formed by the large diameter part of the extension pin and engaged with the magnet fasteners.본 발명은 자석 고정구가 구비된 채혈용 손가락 조임줄에 관한 것으로, 더욱 상세하게는 인체의 건강상태와 각종 질병유무를 검사하기 위해 손가락 끝의 혈액을 채취함에 있어서 신축성과 탄력성을 가지는 고무튜브의 양단에 자석 고정구를 연결하여 자력에 의해 손가락을 감아 조인 고무튜브를 고정시킴으로써 고무튜브가 감아 조인 상태를 그대로 유지하여 채혈중에 풀리지 않게 하고 충분한 혈액을 간편하고 손쉽게 채혈할 수 있도록 한 자석 고정구가 구비된 채혈용 손가락 조임줄에 관한 것이다. 본 발명의 자석 고정구가
