<p>This invention is an elongated medical channel assembly (21, 121)including an indwelling channel difining member (22, 122), an external channel defining member (26, 126), and a coupling assembly (25, 125) coupling the channel defining members together at an exit site (27, 127) of the channel assembly from a patient. The coupling assembly (25, 125) is formed for uncoupling of the externalmember (26, 126) with a disconnect force less than the force required to dislodge the indwelling member (22, 122) from an indwelling position in the patient. The positioning of the coupling assembly (25, 125) stabilizes the coupling assembly for reliable release, and reduces the patient's ability to grasp the indwelling member (22, 122). Alternatively, a signal transmitting assembly (121) can be provided with a releasable coupling (125) at the exit site (127). An auxiliary securement device (62, 131) can be used with either channel assembly (21, 121) so that a low disconnect force applied at any one of a wide range of orientations will uncouple the channel defining members. A method also is provided for preventing dislodgement, and for mounting the coupling assembly (25, 125) to an indwelling member (22, 122) to size the medical channel assembly length to the individual patient.</p> |
