Abstract

A closed irrigation and urinary drainage system apparatus having a catheter means for removing fluids from a patient and a drainage inlet tube which may be connected or disconnected from the catheter means by a hinged connector means for transferring such fluids into a distensible collection bag having an outlet tube for emptying it. The hinged connector means includes an upstream hollow socket portion insertable into the catheter means and a downstream adapter portion insertable into the drainage inlet tube and attached by a hinge means to the upstream portion. The system may be closed for drainage or opened to permit access for irrigation by swingably joining or separating the two portions of the connector means which, when joined, are held in fixed and sealed relationship by interior interlocking ring and groove means.

Claims

1. In a drainage system of the type used for removing fluids from a patient, the combination comprising:

a conventional flexible tube catheter means having a distal end which is insertable into the body of the patient and a proximal end;

a connector means joining said catheter means at its proximal end to a drainage inlet tube means with an upstream end and a downstream discharge end, said connector means having an upstream hollow socket portion insertable into said proximal end of said catheter means, and a downstream hollow adapter portion insertable into the upstream end of said drainage inlet tube means, said socket portion and said adapter portion being attached in swingable relationship to each other by hinge means, said hinge means allowing said adapter portion and said socket portion to be joined in sealed relationship so that fluids may be conducted from said catheter means through said connector means to said drainage inlet tube means, and said hinge means alternatively allowing said adapter portion and said socket portion to be separated, thereby permitting access to said system for irrigation and aspiration purposes;

a distensible collection bag for receiving and storing fluids removed from the patient connectable to said downstream discharge end of said drainage inlet tube means; and

an outlet tube means for emptying fluid stored in said collection bag.

2. The combination of claim 1 wherein said upstream hollow socket portion of said connector means is frustoconical in exterior configuration having a series of circumferential ribs disposed on its surface, said ribs being effective to hold said portion of said connector means in fixed, sealable relationship within said proximal end of said flexible tube catheter means.

3. The combination of claim 1 wherein said downstream hollow adapter portion of said connector means comprises a cylindrically-shaped end insertable into and fixed to said upstream end of said drainage inlet tube means, and an opposite plug end having an exterior configuration similar to the interior configuration of said upstream socket portion of said connector means, though of slightly smaller dimension, said plug end being swung into said upstream hollow socket portion on said hinge means and joined to said upstream hollow socket portion of said connector means by locking means, said locking means being effective to hold said adapter portion and said socket portion in fixed, sealed relationship.

4. The combination of claim 3 wherein said locking means comprises raised annular means disposed about the circumference of said plug end of said adapter portion, said annular means being fittable into depressed groove means similarly disposed in corresponding position about the interior circumference of said upstream hollow socket portion of said connector means.

5. In a drainage system of the type used for removing fluids from a patient and including a conventional flexible tube catheter means having a distal end and a proximal end and in communication through a drainage inlet tube means having an upstream end and a downstream end with a distensible collection bag means for holding and containing the fluids removed from the patient and having an outlet tube means for emptying said bag means, the improvement comprising, connector means joining said catheter means to said tube means in hinged relationship, thereby permitting temporary disengagement of said catheter means from said inlet tube means, said connector means including an upstream hollow socket portion insertable into the proximal end of said catheter means, and a downstream hollow adapter portion having a cylindrical end insertable into the upstream opening of said drainage inlet tube means and a plug end insertable into said upstream hollow socket portion of said connector means, said hollow adapter portion and said hollow socket portion being swingably attached to one another by hinge means and having corresponding locking means disposed in each portion to prevent relative movement and leakage when joined together to form a closed drainage system.

6. The connector means of claim 5 wherein the hollow upstream socket portion of said connector means includes an exterior shell of frusto-conical configuration having a series of raised ribs disposed circumferentially about its surface, said ribs being effective to fixedly and sealably maintain said socket portion within the proximal end of said catheter means.

7. The connector means of claim 5 wherein said locking means includes raised annular means circumferentially disposed about said plug end of said hollow adapter portion, said raised annular means corresponding to depressed annular means disposed about the interior circumference of said hollow socket portion, said raised annular means fitting into said depressed annular means to join said adapter portion and said socket portion in fixed, sealed relationship when said plug end is swingably inserted into said hollow socket portion.
