ABSTRACT:
A subcutaneous access site to aid in the delivery of chemotherapeutic or analgesic drugs to the blood stream or to any body cavity. The device embodies a specially supported septum which exhibits exceptional resealing characteristics. In this regard, the device includes a rigid inner ring adapted to create uniform circumferential compression on the septum member to enhance site resealing even when standard twelve degree beveled hypodermic syringe needles are used. Additionally, the device is uniquely configured to give immediate feedback to the caregiver if the needle misses the target, thereby minimizing accidental subcutaneous injections.
