PROBLEM TO BE SOLVED: To provide a compact and inexpensive tourniquet which stops bleeding by gradually lowering the pressure in a balloon via a decompression device, while pressing a hemostasis part with the balloon.SOLUTION: The tourniquet includes a balloon which presses a hemostasis part, a band body for fixing the balloon to the hemostasis part, and a decompression device 31 which communicates with the balloon and discharges a fluid pressed in the balloon to gradually reduce the pressure in the balloon. The decompression device 31 includes: a reception body 35 an elastic core 33 which is housed in the reception body 35 and has a through hole 39 formed for determining a flow rate of a fluid passing through the decompression device 31 and a cover body 37 which is screwed to and locked in the reception body 35 to compress the core 33. The through hole 39 is varied in size according to the fastening amount of the cover body 37, and adjusts the fastening amount of the cover body 37 to adjust the discharge flow rate of the fluid pressed into the balloon.COPYRIGHT: (C)2013,JPO&INPIT【課題】小型化が可能で安価に製造可能な、バルーンで止血部位を圧迫しつつ減圧装置を介してバルーンの圧力を漸次低下させ止血する止血器具を提供する。【解決手段】止血部位を圧迫するバルーンと、前記バルーンを止血部位に固定可能な帯体と、前記バルーンに連通し、前記バルーンに圧入された流体を放出しバルーン内の圧力を漸次減圧する減圧装置31とを備え、前記減圧装置31は、受体35と、前記受体35内に収納された、該減圧装置31を通過する流体の流量を決める貫通孔39が穿設された弾性を有するコア33と、前記受体35に螺合し締め込むことで前記コア33を圧縮する蓋体37とを有し、前記貫通孔39は、前記蓋体37の締め込み量に応じて大きさを可変させ、前記蓋体37の締め込み量を調整することで前記バルーンに圧入された流体の放出流量を調整可能なことを特徴とする。【選択図】図3
