Hemostasis valve device comprising;
- an insertion tube which has a guide hole into which different catheters such as a tube, a guide wire, or a catheter are inserted along a longitudinal central axis formed inside in a penetrating manner has a hose connector connected to a hose into which a needle or a catheter is inserted coupled to the lower portion, and has a threaded portion formed on the outer circumference of the upper portion;
- an elastic first sealing member which is inserted into and seated in the upper portion of the insertion rube, and has a through hole formed along a longitudinal central axis;
- a fastening tube which has an introduction hole inserted into the upper portion of the insertion rube along a longitudinal central axis formed inside, has a protrusion with an extended diameter forced at the upper portion, of the introduction hole, has a spring receiver formed on the outer circumference of the introduction hole, and has another threaded portion engaging with the threaded portion, which is forced on the outer circumference of the upper portion of the insertion tube, formed on the inner circumference of the spring receiver;
- an elastic second sealing member which is inserted into and seated on the protrusion formed in the upper portion of the fastening tube, and has an incision hole in a circular or “+” shape formed on the top;
- a spring which is inserted into the .spring receiver formed on the outer circumference of the fastening tube, and performs an elastic action according whether an external force is applied;
- a pressurising piece which has a pressurising hole formed in the center of the top in a projecting manner in order to maintain a state in which the hole adheres to the circumference of the incision hole in a circular or shape on the second sealing member, has inclined planes formed on an edge of the upper portion in an outwardly opening manner, and is mounted in a state in which an edge of the lower end adheres to the upper end of the spring all the time;
- push buttons which are mounted on opposing sides of the pressurizing piece, and upwardly slide along the inclined planes on the pressurising piece so as to press the pressurising piece downwardly when a user pushes the buttons in a state in which tapered surfaces having the same slope as the inclined planes on the pressurizing piece are formed on the inner circumference of the upper portion of the buttons;
- and
- a body which allows the push buttons to be inserted into and coupled to the body, and has another through hole, which communicates with the pressurizing hole on the pressurising piece, formed in the center.
