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 side, which plate is made of a material more rigid than the band and at least a portion of which is curved toward the inner peripheral side, 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.

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, and a balloon which is connected to the band and which inflates when a fluid is introduced therein;
wherein the balloon, following inflation, undergoes a decrease in internal pressure over time so that the internal pressure 60 minutes after inflation is 20 to 70% of the initial internal pressure. - View Dependent Claims (16, 17, 18, 19, 20)
