ABSTRACT:
There is disclosed a winged infusion apparatus for use with patient implantable access ports. Essentially, the apparatus includes a composite disc housing which is circular in configuration and has integrally formed therewith two winged sections which overlie arcuate apertures in the sides of the disc. A cannula is embedded within the internal body of the disc, and via a right angle bend the cannula emanates from the bottom surface of the disc at a central location. The winged members are operable so that they can be grasped by a user and placed in an upright position via integral hinges associated with each winged member. In this manner the user can then insert the cannula into an axis port which is implanted in a suitable body cavity of a patient and which has an output aperture on the patient's skin. By utilizing the device and due to the fact that the needle is centrally located and based on the position of the winged members, the entire unit has an extremely uniform profile whereby once the winged members are utilized in an upright position as manipulated by the fingers of a practitioner, they spring back so that they are flush with the top surface of the disc. Once the cannula is emplaced into the access port of the patient, the entire unit is taped by means of a suitable surgical tape onto the skin of the patient to thereby hold the entire unit in a rigid and fixed position.
