Abstract
A calibrated disconnect joint for use with indwelling urethral balloon catheters is included between main portions of a catheter-drainage tube (10) and a bag-drainage tube (16). The calibrated disconnect joint includes male and female portions (or tubularly-shaped wall members) (54, 60; 70, 72; 90, 92; 110, 112) with one of these being a ribbed portion and the other being a grooved portion. If a tension of between 1/2 pound and 4 pounds, preferably between 21/2 and 3 pounds, is applied to the calibrated disconnect joint, the ribbed and grooved portions separate from one another to allow the main portions of the catheter-drainage and bag-drainage tubes to separate. Valves (86, 88) which automatically close their respective lumens upon separation are included on each of the ribbed and grooved portions so that upon separation little or no fluid escapes and there is a barrier to bacteria invasion.
