Abstract
Radial artery compression devices with an inflatable chamber and a substantially rigid frame are disclosed. The inflatable chamber of the radial artery compression devices can be inflated and then deflated according to a predetermined protocol. Some substantially rigid frames can form a wall of the inflatable chamber. Some substantially rigid frames can include indicia to facilitate positioning of the inflatable chamber relative to a puncture site of a patient.
Claims17
A radial artery compression device, the device comprising:
- a substantially rigid frame, the frame comprising an outer surface and an inner surface, wherein at least a portion of the frame is transparent;
- a flexible sheet that is coupled to the frame, wherein at least a portion of the sheet is transparent;
- an inflatable chamber that is at least partially defined by the inner surface of the frame and the flexible sheet;
- a first indicium positioned directly on the frame;
- and
- a second indicium positioned directly on the frame, wherein the second indicium is axially offset from the first indicium.
A radial artery compression device comprising:
- a substantially rigid frame;
- a wristband for securing the substantially rigid frame adjacent to a wrist of a patient;
- an inflatable chamber for applying pressure to a radial access site of a patient;
- a first indicium disposed directly on the substantially rigid frame;
- and
- a second indicium disposed directly on the substantially rigid frame, wherein the second indicium is axially offset from the first indicium;
- wherein at least a portion of the substantially rigid frame and at least a portion of the inflatable chamber are transparent;
- wherein the radial artery compression device is configured such that alignment of the first indicium with a puncture site in a patient's skin positions the second indicium and the inflatable chamber directly over an arteriotomy site of the patient, and
- wherein the arteriotomy site is located offset from the puncture site.
