  • 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.

  • Publication number: 20130282048
    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: 8481805
    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 wrist of the patient, wherein the hemostatic device also includes a curved plate, a balloon and a marker used to position the balloon at the puncture site, and wherein the flexible band, the curved plate and the balloon are substantially transparent. The wrapping of the flexible band around the wrist of the patient involves wrapping the flexible band around the wrist of the patient while the balloon is in an uninflated state. The wrapping can also take place while an introducer sheath is in place at the puncture site. The method also involves using the marker to position balloon relative to the puncture site such that the balloon overlies the puncture site, introducing a fluid into the balloon and inflating the balloon, and maintaining inflation of the balloon and compression against the puncture site.

  • Patent number: 8028835
    Abstract: A transaction management system is capable of simply and accurately gathering information about the use of medical products with minimized human errors and automatically executing issuance of invoices of suppliers and restocking of used products on the basis of the results of use of products deposited at medical centers. The system comprises a computer system having an antenna electrically connected to a reader and a medical product encapsulated in a sterilized environment in a package. The package is provided with an IC tag arranged such that signal transmission and/or reception is disabled while the package remains unopened so that the medical product is in the sterilized condition. The IC tag becomes wirelessly communicable with the antenna when the package is opened to remove the medical product.
