Abstract:
1. A female external catheter device comprising: a urinary tube having proximal and distal ends intercoupling a passage for receiving therethrough the discharge of urine from the urethera a collection means; said urinary tube distal end for coupling to a collection means; said collection means comprising a storage bag, strap means for attaching the storage bag about the female leg and means for coupling the distal end of the urinary tube to the storage bag with the storage bag being positioned about the female leg so as to discharge urine under gravity from the urinary tube to the storage bag; a single piece resilient and deformable flared flange member that is formed integral with the proximal end of the urinary tube, that has a centered port contiguous with the urinary tube passage, that has a closed and continuous peripheral edge that at least in part defines an annular proximal facing contact surface and an opposed annular distal facing contact surface, and that the closed and continuous peripheral edge covers an area that is greater than the cross-sectional area of the urinary tube; the urinary tube being the only discharge passage for urine from the resilient and deformable flared flange member; and an adhesive component disposed on the annular proximal facing contact surface and including a peel-off tab covering the adhesive component and removable to expose an adhesive layer; said resilient and deformable flared flange member being applied by manual contact with the annular distal facing contact surface so as to adhere the adhesive layer on the annular proximal facing contact surface at the fossa navicularis by means of the adhesive component; said resilient and deformable flared flange member closed and continuous peripheral edge constructed and arranged so as to be within the bounds defined by the labium minus when applied; said resilient and deformable flared flange member in its applied position establishing an alignment between the port and the uretheral meatus; wherein the resilient and deformable flange member is substantially oval shaped at its peripheral edge; wherein the length L of the substantially oval shape is greater than the width W thereof, and with the width W extending to fit directly between the labium minus folds; wherein the width W measured upwardly from the center of the centered port by a predetermined distance is less than the width W measured downwardly from the center of the centered port by the same predetermined distance so as to provide an asymmetric shape in an upward downward direction; wherein the thickness of the resilient and deformable flange member is on the order of 1 millimeter and the closed and continuous peripheral edge of the resilient and deformable flared flange member terminates short of the vagina so as to expose the vagina; wherein there is an absence of any catheter extending into the uretheral meatus as the urinary tube is the only means for discharge of urine from the uretheral meatus; wherein the mean diameter of the closed and continuous peripheral edge is in a range between 15 and 30 millimeters; wherein the closed and continuous peripheral edge of the single piece is resilient and deformable flared flange member is defined by a smooth, uninterrupted peripheral edge line; wherein the wall thickness of the urinary tube is greater than the thickness of the resilient and deformable flange member; and wherein the urinary tube wall thickness is on the order of 1-2 millimeters.
