## Abstract

The present invention relates to a hemostasis valve device which allows a wire or a catheter to be inserted into the left or right coronary artery via the femoral artery or an arm artery when a Cardiac Catheterization or Percutaneous Transluminal Coronary Angioplasty operation is performed, wherein two independent sealing members are opened and closed by press and release actions of push buttons coupled to a body and the rotation of a fastening tube, respectively, so that the leakage or blood or the inflow of outside air is simply and effectively blocked during the operation, and a drug influx tube for allowing a medicine such as a thrombolytic drug to flow into a patient during the operation pivots and is adjusted in a stepwise manner within a certain range of angles according to body conditions or movements of the patient.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The hemostasis valve device according to claim 1, characterised in that the device comprises
a pivot guiding piece which is formed in the middle of the insertion tube in an outwardly projecting manner and a disk shape, has a saw-toothed portion formed on the enter circumference within a certain range of angels, and has a drug guide hole, which communicate with the guide hole in the insertion tube, formed on one inner side, and
a pivot adjusting piece which is coupled to the outside of the pivot guiding piece in a covering manner, has another saw-toothed portion formed on the inner circumference corresponding to the saw-toothed portion on the pivot guiding piece so that the two saw-toothed portions engage with each other, and has a drug influx tube formed in a position corresponding to the drug guide hole on the pivot guiding piece.

### Claim 3 (depends on 2)

The hemostasis valve device according to claim 2, characterised in that the drug guide hole on the pivot guiding piece is forced in such a manner that the one opening far from the insertion tube is wider, while the other opening close to the insertion tube is narrower in order to correspond to the range of pivoting movement of the drug influx tube on the pivot adjusting piece.
