The catheter mount passageway (15) is sealed with an elastomeric seal (16) including a perforation or slit (17). A connector (12) with a piercing member is associated with the suction tube (9). When the connector is attached to the catheter mount the piercing member (20) pierces the seal (16) such that the suction tube (9) can pass through the connector (6) and catheter mount. ## Claims ### Claim 1 A catheter tube connector for a suction system, said catheter tube connector comprising: an outer cup-shaped fitting; an inner cup-shaped fitting nested within said outer cup-shaped fitting; and a piercing member nested within said inner cup-shaped fitting and integrally formed with said outer cup-shaped fitting, said piercing member adapted to pierce a seal; a rim of said outer cup-shaped fitting extending beyond a rim of said inner cup-shaped fitting; said piercing member extending beyond said rim of said outer cup-shaped fitting; a first end of said catheter tube connector being adapted to be in communication with a suction system; a second end of said catheter tube connector being adapted to be releasably connected to a catheter mount. ### Claim 2 (depends on 1) The catheter tube connector of claim 1, wherein said catheter tube connector comprises a releasable locking feature configured to prevent inadvertent release of said catheter tube connector from said catheter mount. ### Claim 3 (depends on 1) The catheter tube connector of claim 1, further comprising a releasable lockable bayonet fitting to prevent inadvertent release of said catheter tube connector from said catheter mount. ### Claim 4 (depends on 1) The catheter tube connector of claim 1, wherein said outer cup-shaped fitting is fitted with a releasable lockable bayonet fitting. ### Claim 5 (depends on 1) The catheter tube connector of claim 1, further comprising a washer configured to wipe a suction tube upon removal of said suction tube from said catheter tube connector. ### Claim 6 (depends on 1) The catheter tube connector of claim 1, further comprising a seal configured to wipe a suction tube upon removal of said suction tube from said catheter tube connector. ### Claim 7 (depends on 1) The catheter tube connector of claim 1, further comprising a lumen adapted to allow a suction tube to pass through said piercing member. ### Claim 8 (depends on 1) The catheter tube connector of claim 1, further comprising a seal positioned within said catheter tube connector. ### Claim 9 (depends on 8) The catheter tube connector of claim 8, wherein said seal is positioned between said piercing member and said first end of said catheter tube connector. ### Claim 10 (depends on 8) The catheter tube connector of claim 8, wherein said seal surrounds a lumen extending through said piercing member. ### Claim 11 (depends on 1) The catheter tube connector of claim 1, further comprising an intermediate region between said outer cup-shaped fitting and said first end of said catheter tube connector, said intermediate region comprising a reduced diameter compared to said outer-shaped fitting and said first end of said catheter tube connector. ### Claim 12 (depends on 1) The catheter tube connector of claim 1, wherein said rim of said inner cup-shaped fitting is configured to directly contact a seal located on an outer edge of said catheter mount passageway, such that said piercing member pierces said seal when said catheter tube connector and said catheter mount are connected. ### Claim 13 (depends on 12) The catheter tube connector of claim 12, wherein said piercing member is adapted to allow a suction tube to pass through said piercing member and into said catheter mount passageway without said suction tube contacting said seal. ### Claim 14 (depends on 7) The catheter tube connector of claim 7, wherein said piercing member is configured to fit snugly with said suction tube.
