Hemostatic device
First Claim
1. A hemostatic device comprising:
- a flexible band adapted to be wrapped around a limb of a patient at a puncture site on the limb where bleeding is to be stopped, the band possessing opposite surfaces;
means for securing the band in a wrapped state to the patient'"'"'s limb;
a balloon which is connected to one of the surfaces of the band and which inflates when a fluid is introduced therein;
a curved plate made of a material more rigid than the band and held by the band in such a way that a part of the curved plate overlaps with the balloon and a remainder of the curved plate does not overlap with the balloon, anda marker for positioning a center of the balloon at the site where bleeding is to be stopped, wherein the band, the balloon, and the curved plate are made of materials which allow visualization of the site where bleeding is to be stopped, andwherein the marker has a color that enables the balloon to be properly positioned at the puncture site,wherein the band has a center portion and opposing side end portions in a longitudinal direction of the band,wherein the center portion of the band has a double layer construction defining a curved plate holder and the curved plate is inserted into a gap in the double layer construction such that the curved plate is thereby held in the band, andwherein the opposing side end portions of the band have a single layer construction such that the opposing side end portions do not form the curved plate holder.

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.

17. A hemostatic device comprising:
-
a longitudinally extending flexible band adapted to be wrapped around a limb of a patient at a puncture site on the limb where bleeding is to be stopped, the band possessing opposing side end portions spaced apart in a lengthwise direction of the longitudinally extending flexible band as well as a center portion positioned between the opposing side end portions in the lengthwise direction of the band, the band also possessing opposite surfaces; means for securing the band in a wrapped state around the patient'"'"'s limb; a balloon inflatable when a fluid is introduced into the balloon, the balloon possessing oppositely arranged and spaced apart first and second sides, the first side of the balloon being connected to one of the surfaces of the band; a curved plate that is elongated in the lengthwise direction of the longitudinally extending flexible band, the curved plate being made of a material more rigid than the band and positioned so that a part of the curved plate overlaps the balloon and a remainder of the curved plate does not overlap the balloon, the curved plate including a flat portion and a curved portion that are spaced apart in the lengthwise direction of the longitudinally extending flexible band; a marker for positioning a center of the balloon at the site where bleeding is to be stopped, wherein the band, the balloon, and the curved plate are made of materials which allow visualization of the site where bleeding is to be stopped, and wherein the marker has a visually identifiable color enabling the balloon to be properly positioned at the puncture site; wherein the center portion of the band has a double layer construction defining a curved plate holder and the curved plate is inserted into a gap in the double layer construction such that the curved plate is held in the band; and wherein the opposing side end portions of the band have a single layer construction such that the opposing side end portions do not form the curved plate holder. - View Dependent Claims (18, 19, 20)
