Urinary catheter package and lubricator therefor with combined gripping and sealing means
First Claim
Patent Images
1. A lubricating device for a urinary catheter, comprising a guide housing having proximal and distal end portions defining a lubricant chamber therebetween;
- a body of lubricant within said chamber;
said proximal end portion including a first end wall having an opening therethrough for receiving a catheter extending through said opening and into said body of lubricant;
said first end wall being deformable and shape-recoverable and having edges defining said opening for firmly and sealingly engaging unlubricated outer surface portions of a catheter for restraining longitudinal movement of such catheter until a threshold level of axial force is applied thereto.

Abstract
A urinary catheter package takes the form of a pouch containing a catheter and a lubricating device. The lubricating device comprises a housing with distal and proximal end portions and a lubricant-containing chamber therebetween. A frusto-conical collar at the proximal end of the device performs dual functions of preventing lubricant leakage into the pouch and unintentional sliding movement of the catheter when the package is in use.
