Patent ID: 7641242

Claim:
A compression connection to connect fluidic system components comprising: a first sealing device having a first elongated body with entry and exit openings at opposite ends, a first flange at the entry, a first cylindrical bore extending from the entry to the exit to hold a tube inside the bore, said first elongated body having a first frusto-conical tapered mating surface originating between said flange and the exit and extending to the exit; and a second sealing device having a second elongated body with entry and exit openings at opposite ends, a second flange at the entry, a second bore extending from the entry to the exit, said second bore proximate the entry having a second frusto-conical tapered mating surface for receiving the oppositely shaped first frusto-conical tapered mating surface of the first sealing device, said second frusto-conical tapered mating surface terminates in a second cylindrical portion of the second bore extending into the second elongated body, said second cylindrical bore having a diameter larger than the outer diameter of said tube, a drive force mechanism to provide a substantially rotational torque-free, axial drive force on one or both flanges to urge the first and second sealing devices towards each other and thereby create a leak-resistant seal between the first and second sealing devices by mating the first tapered frusto-conical tapered mating surface of the first sealing device with the oppositely shaped frusto-conical tapered mating surface of the second sealing device to resiliently compress the diameter of the first cylindrical bore and thereby seal the circumference of the tube; a force measurement sensor to measure the axial force compressing the first sealing device; and a force measurement system to receive feedback from the force measurement sensor and adjust the drive force mechanism to achieve a desired compression force.
