Abstract
A prelubricated urinary catheter and package assembly for use in draining the bladder through the urethra comprising an elongate catheter tube with a lubricant on the projecting end thereof and a package assembly receiving the catheter therein an arrangement for isolating the lubricant on the projecting end of the catheter from the rest of the catheter in the catheter receiving cavity.
Claims5
A prelubricated urinary catheter and package assembly for use in draining the bladder through the urethra comprising:
- a) an elongate catheter tube defining a projecting end and a drainage end at opposite ends thereof and defining a drainage passage extending from said projecting end to said drainage end so that fluids in the bladder can drain therethrough when said projecting end of said catheter tube is inserted into the bladder through the urethra;
- b) a lubricant on the projecting end of said catheter;
- and
- c) a package assembly comprising:
- a flexible primary receptacle defining a primary catheter receiving cavity therein for stowing said catheter, said primary catheter receiving cavity sized and shaped to stow said catheter in a generally U-shaped configuration;
- isolation means comprising a flexible secondary receptacle defining a secondary projecting end receiving cavity therein and a secondary access opening to said secondary receiving cavity removably receiving the projecting end of said catheter with the lubricant thereon to isolate the lubricant from said primary cavity, said secondary receptacle removable from the projecting end of said catheter without removing the lubricant from said catheter,
- said primary receptacle defining a primary access opening to said primary cavity so that said catheter and said secondary receptacle with the projecting end of said catheter therein can be removably inserted into said primary cavity in said primary receptacle;
- and
- an enclosing receptacle defining a sterile cavity sealably receiving said primary and secondary receptacles and said catheter with the lubricant thereon therein.

A prelubricated urinary catheter and package assembly for use in draining the bladder through the urethra comprising:
- a) an elongate catheter tube having a projecting end and an opposite end and defining a drainage passage extending therethrough so that fluids in the bladder can drain therethrough when said projecting end of said catheter tube is inserted into the bladder through the urethra;
- b) a lubricant on said projecting end of said catheter;
- and
- c) a package assembly including:
- a thin flexible tubular sheath having opposed sides defining a catheter receiving cavity therein sized to hold said catheter tube in a U-shaped configuration and in which said catheter with said lubricant thereon is housed in the U-shaped configuration, and
- a septum weld sealing said sides of said tubular sheath together between the ends of the catheter so as to isolate the lubricated projecting end of the catheter from the rest of the catheter.
3 more elements
A method of packaging catheters comprising the steps of:
- a) applying a lubricant to the projecting end of the catheter and not to the drainage end of the catheter;
- and,
- b) enclosing the catheter in a package assembly so that the lubricant and the projecting end of the catheter is isolated from the rest of the catheter to limit the area of the catheter coated with lubricant while in the package assembly, and further comprising the substeps of:
- b1) forming the catheter in a U-shaped configuration,
- b2) inserting the catheter in the U-shaped configuration into a tubular plastic sheath, and
- b3) heat sealing the sides of the plastic sheath together between the ends of the catheter so as to isolate the lubricated projecting end of the catheter from the rest of the catheter.
