Hemostatic device
DCFirst 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, the 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 provided on the inner peripheral side of the curved plate at a position deviated to a first end of the curved plate from a center portion of the curved plate in the lengthwise direction of the band, and the main balloon is connected to the band by a connector only on a side of the main balloon adjacent the first end of the curved plate, wherein the main balloon inflates when a fluid is introduced therein,the curved plate possessing a curved portion between the center portion and the first end of the curved plate, anda pressing member which is provided between the curved plate and the main balloon so that at least a portion thereof overlaps with the main balloon and which is adapted for pressing against the main 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.

10. 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 by a connector only on a side of the balloon adjacent a first end of the curved plate and which inflates when a fluid is introduced therein; and a curved plate overlapping the balloon and possessing an inner peripheral side, at least a portion of the curved plate being curved toward the inner peripheral side; the balloon being offset from a center of the curved plate towards the first end of the curved plate in the lengthwise direction of the band, the curved plate possessing a curved portion between the center and the first end of the curved plate. 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 (11, 12, 13, 14, 17)

18. 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 side, the substantially transparent curved plate is 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 side; a balloon which is provided on the inner peripheral side of the substantially transparent curved plate at a position deviated to 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, wherein the balloon inflates when a fluid is introduced; and the substantially transparent curved plate possessing a curved portion between the center portion and the first end of the curved plate. - View Dependent Claims (19)
