Abstract
The invention comprises an infusion device for infusing fluids to a patient having a plurality of, preferably two, enclosed open cavities, equipped with self-sealing septums. The device comprises a housing having a base, a cap, and a dual-port stem exiting the base and communicating with the open cavities. The cap comprises a tactile raised locating ridge positioned between, and adjacent to, the septums or other self-sealing means so configured that a doctor can simultaneously determine where each septum is located as soon as he locates the single ridge. A doctor can also differentiate between each septum, and determine the location of structures associated with each septum. Furthermore, the ridge is so configured that it does not enclose an area of tissue of the patient, thereby precluding the problem of necrosis.
