Abstract

A multiple needle holder and multiple channel subcutaneous infusion port are disclosed. The multiple needle holder carries a plurality of needles which are each in separate fluid communication with a lumen of a plurality of lumens in a multilumen catheter. The multiple infusion port includes a septum which overlies a plurality of isolated chambers. Each chamber is accessed by a tube which connects to a different lumen of a subcutaneous multilumen catheter. When the needles of said needle holder are inserted through the septum of said infusion port each of said needles is in communication with a different one of said isolated chambers.

Claims

1. A multiple needle holder comprising:

a housing having a housing wall surrounding a plurality of conduits extending from a rear face on said housing to a front face;

a plurality of needles secured within said housing so that each of said needles is in communication with one of the said conduits, said needles extending outwards from the front face of said housing;

a plurality of engagement ports on the rear face of said housing each having an opening in communication with one of said conduits, said engagement ports being arranged so as to be matingly aligned with a plurality of ports on a multilumen catheter connector; and

means extending outwardly from said housing wall for engaging a locking mechanism.

2. The needle holder of claim 1 wherein said means for engaging a locking mechanism comprises a flange extending outwardly from said housing wall.

3. The needle holder of claim 1 wherein each of said plurality of needles is curved.

4. The needle holder of claim 1 wherein the rear face of said housing is perpendicular to the front face of said housing.

5. A multiple channel infusion port comprising:

a housing including a housing wall and a base;

a penetrable self-sealing septum held within said housing and having an outer face adjacent at least one opening in said housing and an inner face on the opposite side of said septum from said outer face;

a plurality of isolated chambers adjacent the inner face of said septum;

a sealing wall separating each of said isolated chambers from one another; and

a plurality of access tubes each in communication with one of said isolated chambers for conducting fluid out of the isolated chambers.

6. The mutliple channel infusion port of claim 5 further comprising a multilumen catheter, each lumen of said catheter being in communication with one of said access tubes.

7. The multiple channel infusion port of claim 5 further comprising slot means in the base of said housing for enabling sutures to be applied therethrough.

8. The multiple channel infusion port of claim 5 wherein said housing includes a top portion having solid portions overlying said sealing wall and openings superimposed over said chambers.

9. A multiple needle holder and infusion port comprising:

a housing having a rear face and a front face,

a plurality of needles secured within said housing and extending from the front face of said housing;

a plurality of engagement ports on the rear face of said housing each having an opening in communication with one of said needles; and

an infusion port having a plurality of isolated chambers beneath a self-sealing septum such that when the needles of said needle holder penetrate through said septum each needle is in communication with a different one of said chambers.

10. The multiple needle holder and infusion port of claim 9 wherein said infusion port includes a plurality of access tubes each in communication with one of said isolated chambers for conducting fluid out of the isolated chambers.

11. The multiple needle holder and infusion port of claim 10 further comprising a multilumen catheter, each lumen of said catheter being in communication with one of said access tubes.

12. The multiple needle holder and infusion port of claim 9 further comprising slot means on said infusion port for enabling sutures to be applied therethrough.

13. The multiple needle holder and infusion port of claim 9 wherein the rear face of said housing is perpendicular to the front face of said housing.
