Abstract:

A catheter system in which a silicone rubber catheter tube may be secured to the cylindrically shaped relatively smooth stem of a rigid plastic fitting. A rigid plastic sleeve is adapted to extend over the tube when the latter is fitted onto the stem of the fitting to create a fluid tight seal between the tubing and the fitting. In another embodiment, a boot may first be disposed over a portion of the silicone rubber tubing and then extended over the connection of the rigid sleeve and rubber tubing and plastic fitting. In still a further embodiment a combination boot-sleeve may be employed and sealed to a fitting by means of an ultrasonic weld.
