## Abstract

An implantable venous device is provided with a catheter including a passage; a locking nut including a channel for receipt of the catheter, and an annular convex end; an injection seat including a base, a peripheral wall, and a mounting member projecting out of the wall; a connecting tube projecting out of the mounting member and including a bulged central portion and an annular curved outward end wherein the locking nut is secured onto the bulged central portion; a base member including a groove; a housing including a top opening, a clamping portion on a periphery of the top opening, and a passageway through a bottom edge for receipt of the base member wherein the injection seat is fastened in the housing, and the locking nut is in the groove; and an implant member in the top opening and including a peripheral flange urged downward by the clamping portion.

## Claims

### Claim 1

An implantable venous device comprising:
a catheter including a passage;
a locking nut including a channel for receipt of one end of the catheter, the channel communicating with the passage, and an annular convex end adjacent to the catheter;
an injection seat including a base, a peripheral wall on the base, a space defined by the base and the peripheral wall, and a mounting member projecting out of one side of the peripheral wall wherein the mounting member and the peripheral wall are formed integrally, and a convex portion is formed at a joining portion of the mounting member and the space;
a connecting tube projecting out of the mounting member and formed integrally therewith, the connecting tube including a bulged central portion and an annular curved outward end wherein the locking nut is secured onto the bulged central portion;
a base member including a groove;
a housing including a top opening, a clamping portion on an inner surface of the housing, and a passageway through a bottom edge for receipt of the base member wherein the injection seat is fastened in the housing, and the locking nut is disposed in the groove of the base member; and
an implant member disposed in the top opening and including a peripheral flange urged downward by the clamping portion, the implant member including a bottom disposed above and parallel to the base of the injection seat.

### Claim 2 (depends on 1)

The implantable venous device of claim 1, wherein the locking nut tapers from the annular convex end toward the other end.

### Claim 3 (depends on 1)

The implantable venous device of claim 1, wherein the bulged central portion has a convex shaped and a diameter less than that of the channel so that the passage of the catheter is configured to securely put on the bulged central portion of the connecting tube.

### Claim 4 (depends on 1)

The implantable venous device of claim 1, wherein the connecting tube is spaced apart from the base of the injection seat by a predetermined distance.

### Claim 5 (depends on 1)

The implantable venous device of claim 1, wherein the implant member is formed of silicone so that a needle is configured to be inserted through the implant member and pulled out of the implant member repeatedly.
