Definitions
- the present invention relates to a hemostatic device.
- various medical elongate bodies are introduced into the blood vessel through the puncture site formed by puncturing the blood vessel of the patient's limb such as arm or hand, and treatment and treatment of the lesion site are performed.
- the procedure to do is known.
- U.S. Pat. No. 6,200,009 discloses a hemostatic device for hemostasis at a puncture site formed to allow access to blood vessels running through the hand (including the distal radial artery).
- the hemostatic device of Patent Document 1 includes a pressing member that applies pressure to a puncture site formed in a patient's hand (hereinafter also simply referred to as "puncture site"), and a fixing member for fixing the pressing member to the patient's hand.
- the strap includes a first strap to be placed between the patient's fingers and a second strap to be wrapped around the forearm side of the patient's hand.
- an operator When forming the puncture site on the hand, an operator such as a doctor (hereinafter referred to as the "operator") must place the puncture site at a predetermined position avoiding the metacarpal bone of the index finger and the metacarpal bone of the thumb of the hand. may be set. By setting the puncture site at such a predetermined position, the operator can prevent the puncture device such as the indwelling needle from interfering with the metacarpal bone of each finger when forming the puncture site.
- a doctor hereinafter referred to as the "operator”
- the operator arranges the pressing member and the support member of the hemostatic device of Patent Document 1 so as to overlap the puncture site.
- the support member may be placed on the metacarpal bone of the index finger and the metacarpal bone of the thumb.
- the hemostatic device of Patent Document 1 when the second belt member is wrapped around the patient's hand while the supporting member is placed on the patient's hand as described above, a gap is created between the pressing member and the hand. , the second strap does not fit around the circumference of the patient's hand.
- the pressure member and the support member can be firmly fixed to the patient's hand by strongly tightening the first band of the hemostatic device of Patent Document 1.
- the first band of the hemostatic device of Patent Document 1 needs to be tightly tightened, which may cause pain to the patient. Therefore, in the hemostatic device of Patent Document 1, when the first strap cannot be strongly tightened due to patient pain or the like, the supporting member approaches the body surface of the hand from the fingertip side of the hand toward the forearm side.

止血器具100は、概説すると、図1、図2、図13、図14に示すように、第1穿刺部位p1を覆うように構成された支持部材110と、支持部材110を第1穿刺部位p1に固定するように構成された固定部材120と、支持部材110に接続され、第1穿刺部位を圧迫するように構成された押圧部材180と、を有する。なお、上記の「支持部材110に接続され、」は、押圧部材180が間接的に支持部材110に接続されることを含む。例えば、図1、図5、図6に示すように、押圧部材180(拡張部材180)が接続部材190を介して支持部材110に接続されることは、上記の「支持部材110に接続され、」に含まれる。
押圧部材180は、例えば、図6に示すように、空気等の流体を流入することが可能な内腔183を備えるバルーン等の拡張部材で構成することができる。本実施形態では、以下の説明において、押圧部材180を拡張部材で構成した例を説明する。
支持部材110は、図5、図6、図7、図8、図9に示すように、拡張部材180の先端側に位置し、支持部材110の端部を形成する上端部111と、拡張部材180の基端側に位置し、上端部111と反対側の端部を形成する下端部112と、上端部111と下端部112を繋ぐ側面部113と、を有する。
固定部材120は、図1、図2、図3、図4、図13に示すように、被覆部130と、第1帯体部140と、第2帯体部150と、第3帯体部160と、を有する。
止血器具100は、図1、図2に示すように、拡張部材180に流体を注入するための注入部201を有する。
次に、図10~図14を参照して、止血器具100の第1使用例を説明する。
第3帯体部160に配置される第2固定部位172の形状は、任意に変更することが可能である。例えば、図18に示すように、第2固定部位172は、第3帯体部160の他端部163側に二つの分岐部172a、172bが形成されたハート型のような形状で構成することも可能である。
第2実施形態に係る止血器具100Aは、図19に示すように、固定部材120が第1方向及び第2方向と異なる第3方向に延在する第3帯体部160を備える。
