A flexible, membranous envelope, in a shroud-conduit-collector configuration for sheathing a catheter. In basic mode, the shroud, which essentially envelops the catheter, is partially disposable in an end of the catheter and is extractable therefrom by manipulation of the user. The shroud joins the conduit, that terminates in an integral, yet separable collector. To cure the basic mode's sole limitation, possible infusion of urethra secretions into the opening of the incipiently inserted catheter, a plurality of leaves are attached by their base margins to the shroud exterior, near enough to the inserted opening that their unattached, leading margins can be folded by interleaving them over, and covering, the opening. By this device, an alternate embodiment avoids the catheter-disposed shroud. Other devices are integrated to facilitate manipulation, as well as to aid in after-use separation, sealing and handling of the collector.
