Patent ID: 8551074

Claim:
A system for connecting a length of conduit to a fluid path element, comprising: a compressible sealing element positioned on a distal end of the length of conduit; a first cooperating connector positioned around the length of conduit proximal to the sealing element and comprising a first cooperating connection mechanism; and a second cooperating connector comprising a second cooperating connection mechanism and defining an inner surface and a passage therein in fluid connection with the fluid path element, the first cooperating connection mechanism and the second cooperating connection mechanism each being adapted to form a connection between the first cooperating connector and the second cooperating connector, the connection causing compression of the sealing element; wherein a distal end of the sealing element and the inner surface of the second cooperating connector are tapered to approximately the same angle to create a seal between the inner surface of the second cooperating connector and the distal end of the sealing element; wherein the fluid path element is an injection needle comprising a lumen therethrough and having a length, a diameter of the lumen being flared outward to a larger diameter at a proximal end of the injection needle, an inner diameter of the proximal end of the injection needle being greater than a diameter of the passage of the second cooperating connector, an outer diameter of the proximal end of the injection needle also being flared outward; and further wherein the second cooperating connector further defines a mounting hole in fluid connection with the passage, the mounting hole having a diameter larger than the outer diameter of the proximal end of the injection needle, the system further comprising a sleeve positioned around and contacting substantially the entire length of the injection needle and having an outer diameter at least equal to the outer diameter of the flared proximal end of the injection needle and less than the diameter of the mounting hole, a proximal end of the sleeve abutting the injection needle along the flared proximal end thereof, the sleeve and at least the proximal end of the injection needle being received within the mounting hole.
