Abstract

A securing means for a drainage catheter is disclosed, comprising a securing collar on the catheter, a fixation material being embedded in the collar for use in attaching the catheter firmly and without slippage to a patient. The fixation material may be a suture and needle, a wire clasp, or the like, the fixation material, collar and catheter forming a unitary, readyto-use device. The catheter also carries a fixation band spaced from the securing collar, the band being attached to the catheter to provide further anchoring means for securing the catheter.

Claims

1. A drainage device comprising a catheter, securing means including annular collar means surrounding said catheter and holding it against movement, and unitary fixation means embedded in said collar and at least partially encircling said catheter, said fixation means having free ends extending out of said collar and adapted to provide a secure connection between said catheter and adjacent tissue.

2. The drainage device of claim 1, wherein said collar means comprises a split collar which may be adjustably positioned on said catheter, and sleeve means fastened to the inner surface of said collar to prevent relative movement between said collar and said catheter when said collar is tightened around said catheter.

3. The drainage device of claim 2, wherein said sleeve means is a malleable metal having a plurality of upstanding teeth, said teeth being adapted to grip without puncturing the outer surface of said catheter to anchor said collar to said catheter.

4. The drainage device of claim 3, wherein said collar is generally C-shaped, and sized to fit around said catheter without compressing said catheter.

5. The drainage device of claim 1, wherein said collar is permanently attached to said catheter to prevent relative motion between said catheter and said collar, the collar being of the same material as the catheter and effectively forming an integral part thereof, whereby said catheter, collar, and fixation means comprise a unitary device.

6. The drainage device of claim 1, wherein said unitary fixation means comprises suture means encircling said catheter, with at least one of said free ends carrying a swedged needle.

7. In a drainage device for providing continuous or intermittent drainage of fluids from a body cavity, a catheter having a proximal end for insertion into said cavity and a distal end for drawing off said fluids, and securing means at the proximal end of said catheter for holding said catheter in a selected position, said securing means including a collar and unitary fixation means embedded in said collar and at least partially encircling said catheter, said fixation means extending out of said collar and adapted to provide a quick, secure connection between said catheter and tissue adjacent the opening to said body cavity.

8. The drainage device of claim 7, wherein said collar is permanently attached around said catheter whereby said catheter, collar and fixation means form a unitary device, and whereby said unitary fixation means comprises suture means embedded in and encircling said catheter and having at least one free end to which a needle is permanently affixed, whereby said catheter may be attached to said tissue by said suture.

9. The drainage device of claim 7, wherein said collar is permanently attached around said catheter, said unitary fixation means comprising an anchor wire embedded in and said collar and encircling said catheter and spring clasp means hingedly attached to said anchor wire, said spring clasp means permitting said catheter to be attached to said tissue.

10. The drainage device of claim 7, wherein said Collar is adjustably attached around said catheter, said collar including an inner face comprised of a plurality of small sharp teeth adapted to grip said catheter when said collar is closed around said catheter.

11. The drainage device of claim 10, wherein said fixation means comprises suture means having at least two free ends extending out of said collar for securing said collar to said catheter.

12. The drainage device of claim 7, wherein said catheter is a urethral catheter having a plurality of drainage openings at its proximal end for bladder drainage, said securing means being so located on said catheter as to be adjacent the external urethral meatus of a female patient when said catheter is positioned for urethral bladder drainage, whereby said unitary fixation means permits connection of said catheter to said meatus.

13. The drainage of claim 12, further including a fixation band at the distal end of said catheter for securing said distal end.

14. A drainage device comprising a catheter, securing means including annular collar means surrounding said catheter and holding it against movement, and unitary fixation means including an anchor wire embedded in said collar and spring clasp means attached to said anchor wire.

15. The drainage device of claim 14, wherein said spring clasp means comprises a first curved needle-like arm and a second generally straight arm adapted to receive the end of said first arm.

16. The drainage device of claim 15, wherein said first arm has a sharp, pointed end and said second arm has a hollow end adapted to receive said pointed end of said first arm to close said clasp, said first arm being resilient whereby said clasp can be opened and closed.

17. The drainage device of claim 14, wherein said anchor wire and said spring clasp means are formed with cooperating eyelets whereby said spring clasp may be hingedly attached to said anchor wire.
