Abstract
A hemostatic device is provided to stop bleeding at a puncture site on the wrist of a patient, the device comprising a transparent flexible band to be wrapped at the site where the bleeding is to be stopped, a curved frame having an inner peripheral side and possessing a first curved portion in its first half and a second curved portion in its second half, a first balloon provided on the inner peripheral side in the first half of the curved frame and a second balloon provided on the inner peripheral side in the second half of the curved frame. The bleeding from a first artery is stopped by compressing the first artery at the puncture site using inflation of the first balloon and the blood flow in the first artery is increased by compression of a second artery using inflation of the second balloon.
Core Innovation
The invention relates to a hemostatic device configured to be applied to a limb of a patient. The device includes a flexible band wrapped around at least a portion of the limb at a site where bleeding is to be stopped, and means for securing the band in the wrapped state. The device further includes a member more rigid than the flexible band that is connected to the flexible band so that, in the wrapped state, the member is positioned on the limb at the bleeding site, with an inner peripheral side facing the surface of the limb and an outer peripheral side opposite the inner peripheral side.
At least one portion of the inner peripheral side of the member is a curved portion curved toward the inner peripheral side, with other portions being flat portions. The member has a lengthwise extent with opposite ends spaced apart to define first and second ends, and a center with respect to the lengthwise extent. An inflatable balloon that is inflatable upon introducing fluid into the balloon is positioned on the inner peripheral side of the member and is connected to the flexible band at a position adjacent the center so that, when the flexible band is in the wrapped state and the balloon is inflated, the balloon orients toward the first end of the member.
The balloon applies a compressive force to the site in an oblique direction with respect to the surface of the limb, with the compressive force pointing outwards away from the center of the limb. In embodiments, at least a first portion of the inflatable balloon overlies the curved portion of the inner peripheral side, and the flat portion overlays one or more portions of the balloon as the band is wrapped and the balloon is inflated. In additional embodiments, the flexible band is substantially transparent to allow a site to be viewed through the device, and medication can be applied at a puncture site with a selection limited to antimicrobials, vasodilators, or combinations thereof.
Claims Coverage
The document provides two independent claims. The claims center on an oblique outward compressive inflatable balloon applied at a limb bleeding site using a flexible band secured to a more rigid member with curved and flat portions.
Flexible wrapped band secured to limb bleeding site
A flexible band is applied to the limb in a wrapped state and includes means for securing the band in the wrapped state to apply the hemostatic device to a site where bleeding is to be stopped.
More rigid member positioned on limb with inner curved and flat peripheral portions
A member more rigid than the flexible band is connected so that, when the flexible band is in the wrapped state, the member is positioned on the limb at the site, with an inner peripheral side facing toward the surface of the limb, and the inner peripheral side including a curved portion curved toward the inner peripheral side and other portion(s) being flat portion(s).
Inflatable balloon on inner peripheral side connected adjacent center and oriented toward first end
An inflatable balloon inflatable upon introducing fluid into the balloon is on the inner peripheral side and is connected to the flexible band at a position adjacent the center of the member so that, when inflated, the balloon orients toward the first end of the member.
Oblique outward compressive force via curved and flat positional overlap
With the flexible band in the wrapped state and the balloon inflated, the balloon applies compressive force to the site in an oblique direction relative to the limb surface, pointing outwards away from the center of the limb, with overlapping positioning between the balloon and the curved portion and overlap with at least portions of the flat portion and balloon.
Transparent flexible band for viewing the bleeding site
A flexible band is substantially transparent such that the bleeding site is viewable through the band in a wrapped state.
Across the independent claims, the core inventive structure is a flexible band secured on a limb, a more rigid member having an inner peripheral side with curved and flat portions, and an inflatable balloon connected to the band and oriented toward a first end, such that inflation produces an oblique outward compressive force while the bleeding site is viewable through the band in a wrapped state.
Stated Advantages
The flexible band is substantially transparent to allow a site to be viewed through the device.
Documented Applications
Applied to a limb of a patient at a site where bleeding is to be stopped.
Medication can be applied at a puncture site, with a selection limited to antimicrobials, vasodilators, or combinations thereof.
