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 portion;
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;
a tube communicating with an interior of the balloon;
a connector connected to the tube and into which a syringe is insertable to introduce the fluid in the syringe into the balloon by way of the tube;
the connector including a check valve which closes when the syringe is not connected to the connector to prevent fluid which has been introduced into the balloon from leaking out; and
wherein the curved plate includes opposing side end portions in a longitudinal direction of the band, the curved plate defining, on the side end portion corresponding to the terminal end of the balloon that is connected to the band, a portion with a smaller radius of curvature than the other side end portion of the curved plate.

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.

15. 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; 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; a tube communicating with the balloon; a connector connected to the tube and into which is insertable a syringe to introduce the fluid in the syringe into the balloon by way of the tube; a check valve in the connector which closes when the syringe is not connected to the connector to prevent fluid which has been introduced into the interior of the balloon from leaking out; and wherein the curved includes opposing in a longitudinal direction of the band, the curved plate defining, on the side end portion corresponding to the terminal end of the balloon that is connected to the band, a portion with a smaller radius of curvature than the other side end portion of the curved slate. - View Dependent Claims (16, 17, 18, 19, 20)

21. 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 possessing an interior and being inflatable when a fluid is introduced into the interior of the balloon; the substantially transparent curved plate possessing a curved portion; 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 and so that the curved portion of the substantially transparent curved plate overlies the pressing member; wherein the curved portion of the curved plate is offset towards a first end of the plate from a center portion of the curved plate in the lengthwise direction of the flexible substantially transparent band; a tube communicating with the interior of the balloon; a connector connected to the tube and into which a syringe is insertable to introduce the fluid in the syringe into the interior of the balloon by way of the tube; a check valve in the connector which closes when the syringe is not connected to the connector to prevent fluid which has been introduced into the interior of the balloon from leaking out; and 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 (22, 23)
