Abstract
A hemostatic device includes a flexible band allowed to be wrapped around a wrist in which a radial artery and an ulnar artery run, a hook and loop fastener that secures the band in a state of being wrapped around the wrist, an inflatable portion connected to the band and allowed to press a puncture site of the radial artery by being inflated in response to injection of a fluid, and a pressing member disposed at a different position from a position of the inflatable portion in a longitudinal direction of the band and allowed to press the ulnar artery. Further, a length of the pressing member along the longitudinal direction of the band is shorter than a width of the pressing member along a direction orthogonal to the longitudinal direction of the band.
Claims13
A hemostatic device comprising:
- a flexible band configured to be wrapped around an arm in which a radial artery and an ulnar artery are located, the flexible band possessing a longitudinal extent that extends in a longitudinal direction;
- a securing portion that secures the flexible band on the arm while the flexible band is wrapped around the arm in a wrapped state;
- a support plate that is more rigid than the flexible band, the support plate being mounted on the flexible band so that the support plate and the flexible band move together as a unit;
- an inflatable member connected to the flexible band and expandable upon being inflated in response to introducing fluid into an interior of the inflatable member to press a part of the radial artery to be subjected to hemostasis, the inflatable member possessing oppositely facing surfaces;
- a pressing member disposed at a position spaced from a position of the inflatable member in the longitudinal direction of the flexible band to press the ulnar artery, the pressing member possessing oppositely facing surfaces;
- the pressing member possessing a length along the longitudinal direction of the flexible band that is shorter than a width of the pressing member along a direction orthogonal to the longitudinal direction of the flexible band;
- the inflatable member possessing a first surface disposed on a side that will face the arm when the flexible band is in the wrapped state and a second surface disposed on a side facing the flexible band;
- the pressing member including a third surface disposed on a side that will face the arm when the flexible band is in the wrapped state and a fourth surface disposed on a side facing the flexible band;
- and
- a length of a perpendicular line from the support plate to the first surface is longer than a length of a perpendicular line from the support plate to the third surface when the inflatable portion is inflated in a state in which at least a part of the second surface of the inflatable portion and at least a part of the fourth surface of the pressing member are in contact with a portion of the flexible band in which the support plate is disposed.
A hemostatic device comprising:
- a flexible band configured to be wrapped around an arm in which a radial artery and an ulnar artery are located, the flexible band possessing a longitudinal extent that extends in a longitudinal direction, the flexible band being made of a material;
- a securing portion that secures the flexible band on the arm while the flexible band is wrapped around the arm in a wrapped state;
- a support plate held by the flexible band and made of a material more rigid than the material from which the flexible band is made;
- an inflatable member connected to the flexible band and expandable upon being inflated in response to introducing fluid into an interior of the inflatable member to press a part of the radial artery to be subjected to hemostasis;
- a pressing member disposed at a position spaced from a position of the inflatable portion in the longitudinal direction of the flexible band and configured to press the ulnar artery;
- the inflatable member possessing a first surface disposed on a side that will face the arm when the flexible band is in the wrapper state and a second surface disposed on a side facing the band;
- the pressing member including a third surface disposed on a side that will face the arm when the flexible ban dis in the wrapper state and a fourth surface disposed on a side facing the band;
- and
- a length of a perpendicular line from the support plate to the first surface is longer than a length of a perpendicular line from the support plate to the third surface when the inflatable portion is inflated in a state in which at least a part of the second surface of the inflatable portion and at least a part of the fourth surface of the pressing member are in contact with a portion of the band in which the support plate is disposed.
