Definitions

  • the present invention relates to a hemostatic device.
  • Patent Document 1 discloses a hemostasis device that stops bleeding at a puncture site formed to allow access to blood vessels (including the distal radial artery) running through the hand.
  • the hemostasis device of Patent Document 1 includes a pressing member that applies compressive force to a puncture site formed on a patient's hand (hereinafter also simply referred to as "puncture site"), and a pressing member that is fixed to the patient's hand. and a support member that is made of a material harder than the pressing member and presses the pressing member against the patient's hand.
  • An operator such as a doctor (hereinafter referred to as "operator") places a pressing member and a support member at the puncture site when stopping bleeding at a puncture site formed on a patient's limb.
  • the hemostasis device can stop bleeding at the puncture site by applying compressive force to the puncture site with the press member and the support member disposed at the puncture site.
  • each of the plurality of band parts wrapped around the patient's hand is directly connected to a support member made of a harder material than the pressing member. Therefore, when performing hemostasis using the above-mentioned hemostasis device, the following points arise.
  • the size of the patient's limbs such as hands and the unevenness of the body surface of the limbs vary from patient to patient. Therefore, when attaching a hemostasis device to a patient's limb, it is possible to arrange each band part according to the size, shape, etc. of the patient's limb and the unevenness of the body surface of the limb.
  • the hemostasis device can be appropriately attached to the patient depending on the position of the puncture site formed on the limb.
  • each of the plurality of band members is directly connected to the support member, and therefore the movable range of each band member is narrow in the vicinity of the connection position between the support member and each band member. Therefore, the above-mentioned hemostasis device has a low degree of freedom in the position of wrapping each band around the patient's limb, and there is room for improvement in terms of convenience.
  • the present invention has been made based on the above-mentioned problems, and can be applied to various patients with different limb sizes and shapes, and can be applied to hemostasis at puncture sites formed at different positions.
  • the purpose is to provide a highly convenient hemostasis device.
  • the hemostasis device includes a cover member configured to cover a puncture site formed on a patient, and a pressing member disposed on the cover member and configured to press the puncture site.
  • the cover member includes a main body portion in which the pressing member is located, a first band portion configured to be disposed between the patient's fingers, and extending in a first direction from the main body portion. , a second band part extending from the main body part in a second direction different from the first direction; and a second band part facing the second band part with the pressing member in between, and extending from the main body part to the first band part.
  • the main body portion includes a first region where the support member is located, and the first region, the first band portion, the second band portion, and the third band portion. a second region located between the support member, the second region being made of a material with higher ductility than the support member, and located between the first region and the second band portion.
  • the width of the second region and the width of the second region located between the first region and the third band portion are determined from the distal end side of the support member to the proximal end side of the support member. becomes smaller.
  • the main body of the hemostasis device described above includes a support member that is arranged to overlap the pressing member and is made of a harder material than the pressing member.
  • the main body portion also includes a first region where the support member is located, and a second region located between the first region and the first band portion, the second band portion, and the third band portion.
  • the second region is made of a material that is more ductile than the support member. Therefore, the second region is configured to be movable in accordance with the pulling operation when each band body portion is pulled.
  • the hemostasis device can be applied to various patients with different limb sizes and shapes, and can also be applied to hemostasis at puncture sites formed at different positions. Furthermore, the hemostasis device has a width of the second region located between the first region and the second band portion, and a width of the second region located between the first region and the third band portion. It becomes smaller (narrower) from the distal end side of the support member toward the proximal end side of the support member. Therefore, the hemostasis device can prevent the second region located on the proximal end side of the support member from moving excessively when wrapping the second band portion and the third band portion around the patient's limbs.
  • the hemostasis device when the second band part and the third band part are wrapped around the patient's limb, the position where the second band part and the third band part are wrapped around the patient's limb is on the proximal end side of the support member. You can prevent it from shifting.
  • the hemostasis device can be wrapped around the patient's limb along the direction in which the second band portion and the third band portion are spaced apart from each other with respect to the support member and in a direction substantially horizontal to each other. Therefore, the hemostasis device can wrap the second band portion and the third band portion more firmly around the patient's limb. Therefore, the hemostatic device can improve the compressive force that the pressing member applies to the puncture site when the hemostatic device is attached to the patient's limb.
