Abstract
A hemostatic device is disclosed capable of effectively performing hemostasis on a puncture site of a subject without generating over-pressurization compression. The hemostatic device includes a first hemostatic member and a second hemostatic member which is movable relatively close to or away from the first hemostatic member, pinches a skin around the puncture site of the subject between the first hemostatic member and the second hemostatic member when the second hemostatic member moves toward the first hemostatic member, and performs hemostasis on the puncture site.
Claims20
A hemostatic device configured to perform hemostasis on a puncture site of a subject, the hemostatic device comprising:
- a first support shaft and a first hemostatic member, the first support shaft configured to rotatably support the first hemostatic member;
- a second support shaft and a second hemostatic member, the second support shaft configured to rotatably support the second hemostatic member, the second hemostatic member being movable relatively close to or away from the first hemostatic member and configured to pinch a skin around the puncture site of the subject between the first hemostatic member and the second hemostatic member when the second hemostatic member moves toward the first hemostatic member, each of the first hemostatic member and the second hemostatic member includes a rotatable roller;
- and
- a plate-shaped member configured to be attached to a securing unit, the securing unit configured to secure the first hemostatic member and the second hemostatic member to a hand of the subject, and wherein the plate-shaped member includes a hole that receives the first hemostatic member and the second hemostatic member, and wherein the first hemostatic member and the second hemostatic member are movable within the hole to pinch the skin around the puncture site after the first hemostatic member and the second hemostatic member have contacted the skin of the subject.
A hemostatic device configured to perform hemostasis on a puncture site of a subject, the hemostatic device comprising:
- a first support shaft and a first hemostatic member, the first support shaft configured to rotatably support the first hemostatic member;
- a second support shaft and a second hemostatic member, the second support shaft configured to rotatably support the second hemostatic member, the second hemostatic member being movable relatively close to or away from the first hemostatic member and configured to pinch a skin around the puncture site of the subject between the first hemostatic member and the second hemostatic member when the second hemostatic member moves toward the first hemostatic member, each of the first hemostatic member and the second hemostatic member includes a rotatable roller;
- an arm portion configured to contact and pinch the skin from an outer side of the rotatable rollers of the first hemostatic member and the second hemostatic member;
- and
- a securing unit configured to secure the first hemostatic member, the second hemostatic member, and the arm portion to a hand of the subject.
A hemostatic device configured to perform hemostasis on a puncture site of a subject, the hemostatic device comprising:
- a first hemostatic member, a second hemostatic member, and a third hemostatic member;
- a support member configured to be located above the puncture site of the subject, and wherein the support member is a bent plate-shaped member configured to support the first hemostatic member, the second hemostatic member, and the third hemostatic member;
- and
- an operation member configured to operate each of the first hemostatic member, the second hemostatic member, and the third hemostatic member in a radial direction, the operation member being a string-shaped operation member, each of the first hemostatic member, the second hemostatic member, and the third hemostatic member being connected to the string-shaped operation member, and configured when the string-shaped operation member is pulled, each of the first hemostatic member, the second hemostatic member, and the third hemostatic member move toward each other to pinch the skin around the puncture site, after the first hemostatic member, the second hemostatic member, and the third hemostatic member have contacted the skin of the subject, and when the string-shaped operation member is released, the operation member moves the first hemostatic member, the second hemostatic member, and the third hemostatic member away from each other.
