Abstract

A unitary sheet device for removably securing a catheter to the skin of a patient includes a pair of flaps for being affixed to the skin and a central portion performed in a contour conforming to the catheter hub. When affixed, the central portion and the patient'"'"'s skin together form a receptacle for securely holding the catheter against movement. The central portion may be a tapered conical sheet and the flaps may have adhesive for ease of attachment. A detent is provided, which may include a hole through the central portion of the sheet for engaging a protrusion from the catheter hub. Flexing of the sheet disengages the detent. A non-adhesive tab on one flap aids in removing the device.

Claims

1. A stabilization pad for securely holding to the body of a patient a catheter, having a hub with a stop member projecting radially therefrom and a catheter tube extending therefrom, the pad comprising:

a flexible sheet having;

(i) a central contoured portion defining an inside surface substantially conformal to a portion of the external profile of the catheter hub, such central portion having an aperture extending entirely therethrough for receiving the stop member and securing the hub, and

(ii) a pair of laterally extending flap portions disposed on either side of the central portion, each of such flap portions having on the same side of the sheet as the inside surface a layer of adhesive for adhering the pad to the skin of a patient, wherein a sufficiently large region of each flap portion proximate to the central contoured portion is devoid of adhesive, so that the catheter may be removed from the patient by pinching together the flap portions to separate the central portion from the hub to permit removal of the catheter without detaching the pad from the skin.

2. A stabilization pad according to claim 1, wherein a flap portion includes a protruding tab without a layer of adhesive thereon for use as a grip in removing the pad from the patient.

3. A stabilization pad according to claim 1, wherein the hub has a pair of wings projecting outwardly from opposite sides thereof, such wings defining a plane perpendicular to the stop member and on the opposite side of the hub therefrom, and wherein the portion of each flap devoid of adhesive is just sufficient in area to avoid contact of the wings with the adhesive layer when the pad is used and when the catheter is removed therefrom.
