Abstract
Abstract A catheter affixing and anchoring device including a unitary thermoplastic elastomer pad through which a catheter clasping tunnel is bored to lead a catheter to and through a directional channel. The channel affixes the catheter in a preferred configuration preparatory to anchoring of the device and the catheter assembly to the body of a medical patient by means of a simple procedure and in a manner which allows for easy and repeated cleaning of the insertion site with limited disturbance to the catheter assembly or underlying body tissues. This invention is particularly well suited to use in connection with parenteral infusion, drainage of bodily fluid accumulations and administration of medicaments in liquid form directly to various parts of the body. This invention may also advantageously be used in other applications requiring the infusion of fluids, such as, for example, hyperalimentation.
