  • Publication number: 20200187956
    Abstract: A hemostatic device includes a flexible band adapted to be wrapped around a patient's limb at a site on the limb where bleeding is to be stopped, a portion for securing the band in a wrapped state to the limb, a curved plate which is made of a material more rigid than the band and at least a portion of which is curved toward the inner peripheral side thereof, a main balloon which is provided on the inner peripheral side of the curved plate and which inflates when a fluid is introduced therein, and a pressing member which is provided between the curved plate and the main balloon so that at least a portion thereof overlaps with the balloon and which is adapted for pressing against the balloon. The device provides an excellent hemostatic effect and prevents numbness and poor circulation in areas peripheral to the site of attachment.

  • Patent number: 10058334
    Abstract: A method to stop bleeding at a puncture site of an artery on a patient's arm includes wrapping a flexible band of a hemostatic device around at least a portion of the patient's arm, wherein the hemostatic device also comprises a more rigid member that is more rigid than the flexible band, a balloon, and a visually identifiable marker. The method also involves wrapping the flexible band around at least the portion of the patient's arm while the balloon is in an uninflated state and while an introducer sheath is in place at the puncture site. The visually identifiable marker is used to position the balloon in overlying relation to the puncture site while viewing the puncture site through the balloon and through the more rigid member. Fluid is introduced into the balloon to inflate the balloon to apply a compression force against the puncture site.

  • Publication number: 20130289613
    Abstract: A method to stop bleeding at a puncture site of an artery on a wrist of a patient comprises wrapping a flexible band of a hemostatic device around the patient's wrist, wherein the hemostatic device also includes a curved plate, a balloon and a marker for positioning the balloon at the puncture site, and wherein the flexible band, the curved plate and the balloon are substantially transparent. The balloon is positioned relative to the puncture site using the marker so that the balloon overlies the puncture site and is situated between the plate and the patient's wrist. The method also involves introducing fluid into the balloon after the wrapping the flexible band around the patient's wrist to inflate the balloon so the balloon applies a compressive force to the puncture site, and maintaining inflation of the balloon and compression against the puncture site to stop bleeding from the puncture site.
