Abstract: There is disclosed a catheter device with easily deployed retainer useful in securing medical appliances such as catheters, sensors, tubing, or the like, to a human or other patient. The device includes a catheter, or the like, with a self-adhesive tape which is attached and extends perpendicularly thereto. The self-adhesive tape may be a strip of conventional surgical or first aid adhesive tape and has each of its ends rolled towards the catheter in a scroll-like fashion; the tape preferably is pre-attached to the catheter by adhesive, heat sealing, or the like, and may have a medicine saturated pad on the bottom side to help prevent infection at the wound area. The adaptation of the device with any intravenous catheter does not change standard use in any way in relation to preparation of the site, or actual insertion of the catheter. After the vein has been accessed, the tape is simply unrolled by the thumb and index finger with moderate pressure to secure the catheter to the patient's skin.
