Winged infusion apparatus for patient implantable access ports
First Claim
1. An infusion apparatus for use with an implantable access port which port is positioned on a body surface of a patient to allow the patient to receive various fluids and chemicals for treatment, comprising:
- a disc housing assembly having a top and bottom surface separated by a circumferential sidewall,a cannula imbedded in said disc for a given length and extending from the central region of said bottom surface and adapted to be inserted into said access port,first and second winged members hingedly secured to said top surface of said disc and oriented so that in a first position they are relatively flush with said surface and contained within said surface area and capable of being grasped so that in a second position they are positioned transverse to said surface to allow insertion of said cannula into said access port, wherein when said winged members are released they spring back to assume said first position, whereby said first and said second winged members are flush with said top surface of said disc housing and cannot contact said body surface of said patient due to said separation between said bottom surface and said top surface of said housing afforded by said circumferential sidewall.

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.

10. An infusion apparatus for use with an implantable access device having a port which port is positioned on a body surface of a patient to allow the patient to receive various fluid and chemicals for treatment administered by a practitioner, said infusion apparatus of the type having a cannula directed from a housing to enable insertion of said cannula into said port, the improvement in combination therewith of,
a relatively symmetrical housing having a bottom surface from which said cannula extends at a central portion from said surface and directed relatively transverse thereto, with another portion of said cannula firmly embedded within said housing and having an end directed from said housing for coupling to a delivery tube, said housing having a top surface separated a given distance from said bottom surface by a circumferential sidewall and including left and right winged members hingedly secured to said top surface of said relatively symmetrical housing, said left and right winged members being flush with said top surface in a first position and capable when grasped by said practitioner of extending transverse to said top surface in a second position to enable said practitioner when grasping said left and said right winged members to manipulate and insert said cannula into said access port whereby when said left and said right members are no longer grasped, said members return to said first position and cannot contact said body surface of said patient due to said separation between said bottom surface and said top surface of said housing afforded by said circumferential detail.

16. An infusion apparatus for use with an implantable access port which port is positioned on a body surface of a patient to allow the patient to receive various fluids and chemicals for treatment, comprising
a complete disc housing assembly having a top surface and a bottom surface separated by a circumferential sidewall said housing assembly having a bottom circular housing section including a cannula accommodating channel coextensive with an aperture located in the center of the bottom surface of said bottom circular housing section and a top housing section having a corresponding channel and having a planar central portion; -
a cannula located between said bottom circular housing section and extending for a given length from the central region of said bottom surface and adapted to be inserted into said access port, said given length of said cannula being embedded between said top and said bottom housing sections with said top housing section secured to said bottom housing section; first and second winged members hingedly secured at right and left sides to said planar central portion of said top housing section and oriented so that in a first position they are relatively flush with said top housing section and contained within said surface area of said bottom housing section and capable of being grasped so that in a second position they are positioned transverse to said top housing section to allow insertion of said cannula into said access port wherein when said winged members are released they spring back to assume said first position whereby said first and said second winged members are flush with said top housing section and cannot contact said body surface of said patient due to said separation between said bottom surface and said top surface of said housing afforded by said circumferential sidewall.
