Calibrated disconnect joint for urethral catheter
First Claim
1. A calibrated disconnect joint for use with indwelling urethral balloon catheters, said calibrated disconnect joint comprising:
- a first tubularly-shaped wall member defining a lumen, said tubularly-shaped wall member including a first strong attachment means positioned at a distal end thereof for providing a strong attachment of said first tubularly-shaped wall to said catheter-drainage tube requiring a force greater than 6 pounds axial pull to separate said first tubularly-shaped wall from said catheter-drainage tube, said first tubularly-shaped wall member including a first calibrated connector at a proximal end thereof;
a second tubularly-shaped wall member including a second strong attachment means positioned at a proximal end thereof for providing a strong attachment of said second tubularly-shaped wall to a bag-drainage tube requiring a force of greater than 6 pounds axial pull to separate said second tubularly-shaped wall member from said bag-drainage tube, said second tubularly-shaped wall including a second calibrated connector at a distal end thereof;
wherein one of said first and second tubularly-shaped wall members is a male connector and the other is a female connector, said male and female connectors telescoping together, and wherein said male and female connectors include means for interengaging said connectors with one another to form a sealed coupling which automatically separates said connectors upon receiving a separating tension of between 1/2 and 6 pounds.

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.

12. A urethral catheter system comprising:
-
a catheter-drainage tube having a balloon on a distal end thereof; a bag-drainage tube for being attached to a receptacle bag for receiving fluid passing through said catheter-drainage tube; a calibrated disconnect joint for interconnecting said catheter-drainage tube and said bag-drainage tube, said calibrated tubular connector comprising; a first tubularly-shaped wall member defining a lumen, said first tubularly-shaped wall member including a first strong attachment means positioned at a distal end thereof for providing a strong attachment of said first tubularly-shaped wall to said catheter-drainage tube requiring a force greater than 6 pounds axial pull to separate said first tubularly-shaped wall from said catheter-drainage tube, said first tubularly-shaped wall member including a first calibrated connector at a proximal end thereof; a second tubularly-shaped wall member including a second strong attachment means positioned at a proximal end thereof for providing a strong attachment of said second tubularly-shaped wall to a bag-drainage requiring a force of greater than 6 pounds axial pull to separate said second tubularly-shaped wall member from said drainage-bag, said second tubularly-shaped wall including a second calibrated connector at a distal end thereof; wherein one of said first and second tubularly-shaped wall members is a male connector and the other is a female connector, said male and female connectors telescoping together, and wherein said male and female connectors include means for interengaging said connectors with one another to form a sealed coupling which automatically separates upon receiving a separating tension of between 1/2 and 6 pounds. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. A method of protecting patients using urethral catheter systems comprising catheter-drainage tubes which are held inside of patients by balloons and bag-drainage tubes which are connected to the catheter-drainage tubes external of the patients for channelling fluid passing through the catheter-drainage tubes into retainer bags comprising the step of:
placing a calibrated disconnect joint at the interconnection between the catheter-drainage tube and the bag-drainage tube which automatically disconnects when a separating axial force of between 1/2 and 6 pounds is applied thereto. - View Dependent Claims (22)

23. A catheter joint for use with a catheter, said catheter joint comprising:
-
an elongated tubular housing defining a side port; a hydrophobic filter mounted in said side port for allowing ventilation to an interior passage of said catheter; and a membrane also mounted in said side port for allowing a sampling of fluid material in the interior passage of said catheter with a needle passed therethrough without unduly exposing the interior passage of the catheter to outside atmosphere. - View Dependent Claims (24, 25)
