Claim 6

The container of claim 1 wherein said container comprises a pair of flexible side walls joined together along spaced lines to define each of said compartments.

Claim 7

The container of claim 1 including means for commonly venting at least two of said compartments.

Claim 8

The container of claim 1 including means for draining each of said compartments.

Claim 9

The container of claim 1 wherein said receptacle includes flap means having opening means to receive and support each of said drainage tubes.

Claim 10

The container of claim 1 wherein said container has a pair of drainage tubes, and said receptacle has a pair of compartments.

Claim 11

The container of claim 1 wherein said container has three drainage tubes, and said receptacle has three compartments.

Claim 12

A multi-chamber container for collecting urine from different sources, comprising: a plurality of urine drainage tubes communicating with separate urine sources: a drainage bag having a pair of flexible side walls, means joining said side walls together along lines and defining a plurality of contiguous separate compartments, and a plurality of openings adjacent the upper ends of said compartments extending through a side wall with each of said openings communicating with one of said compartments; a plurality of connectors connecting a downstream end of each of said drainage tubes with one of said openings for simultaneous passage of urine from the drainage tubes to separate compartments and retention therein; and means for venting each of said compartments to the atmosphere.

Claim 13

A multi-chamber container for collecting urine from different sources, comprising: a plurality of urine drainage tubes communicating with separate urine sources: a drainage bag having a pair of flexible side walls, means joining said side walls together along lines and defining a plurality of contiguous separate compartments, and a plurality of openings adjacent the upper ends of said compartments extending through a side wall with each of said openings communicating with one of said compartments; a plurality of connectors connecting a downstream end of each of said drainage tubes with one of said openings for simultaneous passage of urine from the drainage tubes to separate compartments and retention therein; and means for venting each of said compartments to the atmosphere.

Claim 14

The container of claim 11 wherein said connectors comprise drip chambers secured to an outer surface of said side wall around said openings, each of said drip chambers receiving the downstream end of one of said drainage tubes adjacent an upper end of the drip chambers, with the downstream end of the drainage tubes being spaced from the walls of the drip chambers.

Claim 15

The container of claim 11 wherein said receptacle has first and second side-by-side compartments, and said venting means comprises opening means extending through one of said side walls and communicating with said first and second compartments adjacent the juncture of said compartments, an air-permeable filter covering said opening means, and means for securing the filter to said one side wall.

Claim 16

The container of claim 13 wherein the securing means comprises a pair of flexible rings, one of said rings being secured to an outer surface of said one side wall, and the other of said rings being secured to an inner surface of said one side wall, with said filter being located intermediate said rings.

Claim 17

The container of claim 11 wherein the joining means comprises sealing lines in said side walls.

Claim 18

A liquid drainage system for drainage of urine from different sources in a patient, comprising: a flexible receptacle having first and second separate compartments; first and second urine drainage tubes having drainage lumens; means for connecting a downstream end of the first and second tubes to the receptacle with the drainage lumens in the drainage tubes separately communicating with the first and second compartments; a ureteral catheter having a drainage lumen, a drainage eye communicating with the drainage lumen adjacent an upstream end of the ureteral catheter for placement in the patient's ureter, and a downstream end connected to an upstream end of the first drainage tube with the drainage lumen of the ureteral catheter communicating with the drainage lumen of the first drainage tube; and a urinary catheter having a drainage lumen, a drainage eye communicating with the drainage lumen adjacent an upstream end of the urinary catheter for placement in the patient's bladder, a retention member adjacent the upstream end of the urinary catheter, and a downstream end connected to an upstream end of the second drainage tube with the drainage lumen of the urinary catheter in communication with the drainage lumen of the second drainage tube, whereby urine from the patient's ureter and bladder are simultaneously collected in said separate compartments.

Claim 19

A liquid drainage system for drainage of urine from different sources in a patient, comprising: a flexible receptacle having first and second separate compartments; first and second urine drainage tubes having drainage lumens; means for connecting a downstream end of the first and second tubes to the receptacle with the drainage lumens in the drainage tubes separately communicating with the first and second compartments; a ureteral catheter having a drainage lumen, a drainage eye communicating with the drainage lumen adjacent an upstream end of the ureteral catheter for placement in the patient's ureter, and a downstream end connected to an upstream end of the first drainage tube with the drainage lumen of the ureteral catheter communicating with the drainage lumen of the first drainage tube; and a urinary catheter having a drainage lumen, a drainage eye communicating with the drainage lumen adjacent an upstream end of the urinary catheter for placement in the patient's bladder, a retention member adjacent the upstream end of the urinary catheter, and a downstream end connected to an upstream end of the second drainage tube with the drainage lumen of the urinary catheter in communication with the drainage lumen of the second drainage tube, whereby urine from the patient's ureter and bladder are simultaneously collected in said separate compartments.

Claim 20

The drainage system of claim 16 wherein the receptacle includes a third compartment, including a third drainage tube and means for connecting a downstream end of the third drainage tube to the receptacle with the drainage lumen of the third drainage tube in separate communication with the third compartment, and including a second ureteral catheter having a drainage lumen, a drainage eye communicating with the drainage lumen adjacent an upstream end of the second ureteral catheter, and a downstream end connected to the third drainage tube with the drainage lumen of the second ureteral catheter in communication with the drainage lumen of the third tube.

Claim 23

The method of claim 18 including the step of separately and simultaneously draining urine associated with the other kidney through a second ureteral catheter from a location remote the bladder to a third separate compartment in said common drainage receptacle.
