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.

Claims

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 balloon which is connected to the band and which inflates when a fluid is introduced therein; and

a marker for positioning the balloon at the site where bleeding is to be stopped.

2. The hemostatic device of claim 1, wherein the band and the balloon are made of materials which allow visualization of the site where bleeding is to be stopped.

3. The hemostatic device of claim 1, wherein the marker is provided on the balloon.

4. The hemostatic device of claim 1, wherein the marker is provided on the band.

5. The hemostatic device of claim 1, wherein the band holds a curved plate made of a material more rigid than the band in such a way that the curved plate overlaps with the balloon.

6. The hemostatic device of claim 1, further comprising a pressing member adapted 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 overlaps the balloon.

7. The hemostatic device of claim 5, wherein the marker is provided on the curved plate.

8. The hemostatic device of claim 6, wherein the marker is provided on the pressing member.
