Disclosed herein are devices for temporarily restricting the blood flow of an area in a subject. The device includes a restrictor, a bolt and a strip. The restrictor includes a cylindrical body having one open end, one closed end, and a passage therethrough, in which the inner surface of the cylindrical body towards the open end is treaded and a protrusion disposed on the outer surface of the closed end of the body. The strip is preferably made of an elastic material and is coupled to the protrusion of the restrictor at one end, while allowing the other end (i.e., the free end) to circumvent the area before passing through the passage of the cylindrical body to form a loop that can be tightened to restrict the blood flow of the area in the subject. The bolt has a head and a treaded shaft, wherein the bolt is capable of being driven into the cylindrical body through the open end to engage the threaded shaft of the bolt with the threaded inner surface of the cylindrical body until the end of the threaded shaft of the bolt is held against the strip so as to hold the loop in place and thereby restricting the blood flow of the area.在此揭示一種血流暫時阻斷裝置,其係用以暫時阻斷一個體之一特定區域的血流。此血流暫時阻斷裝置包含一限制件、一螺絲以及一束帶。所述之限制件,包含一柱狀體及接合部。所述柱狀體具有一開放端、一封閉端、一橫向貫穿通道,且至少一部分所述之柱狀體內部設有螺紋。所述接合部固接於柱狀體之封閉端外部。所述束帶可由彈性材料製成,且一端與接合部相耦接,另一端(即,束帶之自由端)則可繞過個體之特定區域後,再穿過橫向貫穿通道而形成一迴圈以套住個體之特定區域。所述螺絲,具有一螺頭與一螺桿,係可由柱狀體開放端被螺合進入限制件而與柱狀體內部螺紋相嚙合且使螺桿底部抵靠著該迴圈而固定其位置,以達成限制該個體特定區域之血流的目的。350‧‧‧血流暫時阻斷裝置110‧‧‧螺絲112‧‧‧螺頭114‧‧‧螺桿120‧‧‧限制件121‧‧‧開放端122‧‧‧柱狀體123‧‧‧封閉端124‧‧‧橫向貫穿通道126‧‧‧接合部127‧‧‧接頭130‧‧‧束帶S‧‧‧螺紋
