Abstract

The needle patch has a Huber needle which is encased between a pair of flexible transparent discs. The needle has a depending angled portion which extends through an aperture in the lower disc for insertion in an implanted vascular access device. The lower disc also has an adhesive layer for securement to the skin about the injection site while the upper disc has a projection defining a reservoir above the aperture of the lower disc for dispensing of an antiseptic ointment to the injection site. A rigid housing is integrally formed with the discs to provide a finger gripping portion for insertion of the needle.

Claims

1. A vascular access implant needle patch comprising

a first transparent disc having a centrally disposed aperture;

a needle having a passage for a flow of fluid therethrough, said needle having a main portion extending over said disc and an angled portion extending through said aperture of said disc;

a second transparent disc secured to said first disc with said needle disposed therebetween; and

a rigid housing secured to said discs to define a finger grip, said housing having said main portion of said needle encased therein.

2. A needle patch as set forth in claim 1 which further comprises an adhesive layer on said first disc and a removable sheet disposed over said layer on said first disc.

3. A needle patch as set forth in claim 1 wherein said main portion of said needle extends parallel to said first disc.

4. A needle patch as set forth in claim 1 wherein said main portion of said needle extends at an angle to said first disc.

5. A needle patch as set forth in claim 1 wherein said second disc includes a dome-shaped projection over said aperture in said first disc to define a reservoir for receiving an antiseptic ointment.

6. A needle patch as set forth in claim 5 which further comprises an annular wall extending from said second disc through said aperture in said first disc to define a dam for retaining ointment from said reservoir therein.

7. A needle patch as set forth in claim 1 which further comprises a flexible tube connected to said needle within said housing and extending from said housing.

8. A needle patch comprising

a transparent patch for mounting on a patient, said patch including a centrally disposed aperture and means defining a reservoir above said aperture for receiving an antiseptic ointment;

a rigid housing secured to said patch to define a finger grip; and

a hollow needle having an angled portion extending through said aperture of said patch and perpendicularly from said patch.

9. A needle patch as set forth in claim 8 which further comprises an adhesive layer on said patch for adhering said patch to a patient.

10. A needle patch as set forth in claim 8 wherein said angled portion of said needle is disposed centrally of said patch.

11. A needle patch as set forth in claim 10 wherein said needle has a main portion extending into said housing and which further comprises a flexible tube connected to said main portion of said needle.

12. A needle patch as set forth in claim 8 further comprising an adhesive layer on said patch for securing said patch to a patient and a removable sheet disposed over said adhesive layer to protect said layer.

13. A needle patch as set forth in claim 8 wherein said patch is flexible.

14. A needle patch as set forth in claim 13 wherein said patch includes a pair of discs integrally secured together and said needle includes a main portion extending between said discs.

15. A vascular access implant needle patch comprising

a flexible transparent disc for mounting on a patient;

a second disc secured to said flexible disc;

a rigid housing secured to and extending radially of said second disc to define a finger grip;

a hollow needle having a main portion extending between said discs into said housing and an angled portion extending perpendicularly from a central portion of said flexible disc;

a layer of adhesive on said flexible disc for securing said flexible disc to a patient; and

a removable sheet disposed over said adhesive layer.

16. An implant needle as set forth in claim 15 wherein said second disc includes a dome-shaped projection over said angled portion of said needle to define a reservoir for an antiseptic and said flexible disc includes an aperture aligned with said projection with said angled portion of said needle passing therethrough.

17. An implant needle as set forth in claim 15 wherein said disc has an integral guide channel receiving said main portion of said needle in spaced relation to permit pivoting of said main portion within said channel.

18. A vascular access implant needle patch comprising

a first transparent disc having a centrally disposed aperture;

a needle having a passage for a flow of fluid therethrough, said needle having a main portion extending over said disc and an angled portion extending through said aperture of said disc; and

a second transparent disc secured to said first disc with said needle disposed therebetween, said second disc including a dome-shaped projection over said aperture in said first disc to define a reservoir for receiving an antiseptic ointment.

19. A needle patch as set forth in claim 18 which further comprises an annular wall extending from said second disc through said aperture in said first disc to define a dam for retaining ointment from said reservoir therein.

20. A needle patch as set forth in claim 18 which further comprises a rigid housing secured to said discs to define a finger grip, said housing having said main portion of said needle encased therein.

21. A vascular access implant needle patch comprising a flexible transparent disc for mounting on a patient;

a rigid housing secured to and extending radially of said disc to define a finger grip;

a hollow needle having a main portion extending into said housing and an angled portion extending perpendicularly from a central portion of said disc;

an integral guide channel in said disc receiving said main portion of said needle in spaced relation to permit pivoting of said main portion within said channel;

a layer of adhesive on said disc for securing said disc to a patient; and

a removable sheet disposed over said adhesive layer.
