Hemostatic device
First Claim
1. A hemostatic device comprising:
- a flexible band adapted to be wrapped around a limb of a patient at a site on the limb where bleeding is to be stopped;
means for securing the band in a wrapped state to the patient'"'"'s limb;
a curved plate having an inner peripheral surface, the plate being made of a material more rigid than the band, and the plate having a curved end portion adjacent one end of the curved plate;
a balloon on the inner peripheral surface of the curved plate and configured to be inflated when a fluid is introduced into the balloon;
Wherein the band has a portion including a double layer construction defining a curved plate holder, and the curved plate is positioned in a gap in the double layer construction such that the curved plate is held in the curved plate holder of the band;
wherein the balloon includes a first terminal end, the first terminal end being connected to the band, and the first terminal end being adjacent to the one end of the plate; and
wherein, when the band is wrapped around the limb and inflated, the inflated balloon applies a compressive force to the site in an oblique direction with respect to the surface of the limb.

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.

14. A hemostatic device comprising:
-
a flexible substantially transparent band adapted to be wrapped around a limb of a patient at a site on the limb where bleeding is to be stopped; means for securing the flexible substantially transparent band in a wrapped state to the patient'"'"'s limb; a substantially transparent curved plate having an inner peripheral surface, the substantially transparent curved plate being made of a material more rigid than the flexible substantially transparent band and at least a portion of which is curved toward the inner peripheral surface; a balloon provided on the inner peripheral surface of the substantially transparent curved plate, the balloon being inflatable when a fluid is introduced into the balloon; the substantially transparent curved plate possessing a curved portion offset towards a first end of the substantially transparent curved plate from a center portion of the substantially transparent curved plate in the lengthwise direction of the flexible substantially transparent band; and a pressing member configured to press against the balloon, the pressing member being positioned between the curved plate and the balloon so that at least a portion of the pressing member overlies the balloon; a marker for positioning the balloon at the site where bleeding is to be stopped, the marker being provided on the pressing member. - View Dependent Claims (15, 16)

17. A hemostatic device comprising:
-
a flexible band adapted to be wrapped around a limb of a patient at a site on the limb where bleeding is to be stopped; means for securing the band in a wrapped state to the patient'"'"'s limb; a curved plate having an inner peripheral surface, the plate being made of a material more rigid than the band; a balloon provided on the inner peripheral surface of the curved plate and configured to be inflated when a fluid is introduced into the balloon; a pressing member configured to press against the balloon, the pressing member being positioned between the curved plate and the balloon so that at least a portion of the pressing member overlies the balloon; wherein the balloon includes opposing first and second terminal ends in the lengthwise direction of the flexible band, the balloon being connected to the band at only one of the first and second terminal ends; and wherein the pressing member includes opposing first and second terminal ends in the lengthwise direction of the flexible band, the pressing member being connected to the band at only one of the first and second terminal ends. - View Dependent Claims (18, 19, 20, 21, 22)
