Abstract
A radial compression band is configured to provide hemostatic compression to an arterial access site on the arm of a wearer. The radial compression band includes an elongated arm band that presents an arm opening sized to receive the arm. The arm band presents proximal and distal margins, with the arm opening being defined between the margins.
Core Innovation
The invention relates to a radial compression band configured to provide hemostatic compression to an arterial access site on an arm of a wearer, such as an access site involving an artery for radial access. The band includes an elongated arm band extending circumferentially to present an arm opening sized to receive the arm, with proximal and distal margins defining the arm opening. The arm band is partly sectioned to include circumferentially extending proximal and distal arm band sections.
The arm band presents a circumferential slot defined between the arm band sections along at least half of the circumferential length of the arm band, such that the arm band sections are joined along a circumferential minority of the arm band. Each arm band section defines opposed first and second end portions that are removably connectable to one another, with the proximal arm band section and distal arm band section arranged so the end portions are adjacent to corresponding end portions. The circumferential slot separates the first end portions.
The band provides a pair of pressure adjustment mechanisms, each associated with a respective one of the arm band sections and configured to vary a pressure applied against a portion of the arm underlying the respective arm band section. Each pressure adjustment mechanism comprises an expandable bladder coupled to the respective arm band section, including one bladder having a pressure surface configured to provide hemostatic pressure at the access site. A Doppler probe is supported by the other bladder along the other arm band section for adjustably compressible engagement with the arm, so the Doppler probe senses blood flow through an artery and thereby facilitate arterial patency during hemostasis.
Claims Coverage
The claims coverage centers on one independent claim that defines the overall radial compression band, including a sectioned arm band with a circumferential slot, two expandable bladders for independently varying pressures, and a Doppler probe supported by one bladder to sense blood flow and facilitate arterial patency during hemostasis. Dependent claims refine the structure and arrangement, including extent of the circumferential slot, the access opening, transparent window features, and bistable/coiled configuration with adjustable overlap interconnection.
Sectioned radial band with circumferential slot and removably connectable sections
A radial compression band including an elongated arm band extending circumferentially to present an arm opening, the arm band presenting proximal and distal margins defining the arm opening, the arm band being partly sectioned to include circumferentially extending proximal and distal arm band sections, the arm band presenting a circumferential slot defined between the arm band sections along at least half of the circumferential length such that the arm band sections are joined along a circumferential minority, and each arm band section defining opposed end portions that are removably connectable to one another with the circumferential slot separating the first end portions.
Dual pressure adjustment with expandable bladders on respective band sections
A pair of pressure adjustment mechanisms, each associated with a respective arm band section and configured to vary a pressure applied against a portion of the arm underlying the respective arm band section, each pressure adjustment mechanism comprising an expandable bladder coupled to the respective arm band section, with one bladder having a pressure surface configured to provide hemostatic pressure to the access site.
Doppler probe supported by the other bladder to facilitate arterial patency during hemostasis
A Doppler probe operable to sense blood flow through an artery and thereby facilitate arterial patency during hemostasis of the access site, wherein the Doppler probe is supported by the other one of the bladders along the other one of the arm band sections for adjustably compressible engagement with the arm when the radial compression band is donned.
Circumferential slot extends along at least eighty percent of circumferential length
The arm band presents a circumferential slot extending along at least eighty percent of the circumferential length of the arm band.
Access opening configured to receive an arterial sheath between pressure surface and Doppler probe
A radial compression armband includes an access opening defined along a circumferential slot and located between a pressure surface and a Doppler probe, where the access opening is configured to receive an arterial sheath when the band is worn.
Window section with at least substantially transparent material layer
A window section defined by an at least substantially transparent material layer is provided in a proximal arm band section.
Bistable arm band with coiled and uncoiled configurations
The radial compression band includes an arm band with a bistable construction to assume a coiled configuration or an uncoiled configuration.
Overlapping end portions with complementary hook-and-loop fastener strips in coiled configuration
When the arm band is in the coiled configuration, the arm band sections have overlapping end portions, with complementary hook-and-loop fastener strips adjacent the end portions to provide adjustable interconnection.
Across the independent claim and the identified dependent refinements, the inventive concept combines a sectioned, circumferentially slotted radial compression band with removably connected proximal and distal arm band sections, dual pressure adjustment via expandable bladders, and a Doppler probe supported by the other bladder to sense blood flow and facilitate arterial patency during hemostasis, with further claim refinements directed to extent of the circumferential slot, an access opening for an arterial sheath, transparent window features, and bistable coiled/uncoiled construction with hook-and-loop interconnection.
