Abstract

A safety port needle assembly used to connect an IV line to an implanted port needle receiving port. The assembly includes an L-shaped port needle with an integrally attached horizontal leg member, a vertical leg member, an elongated, fixed main body and a pivotally attached needle arm. The horizontal leg member is longitudinally aligned and attached to the needle arm. The vertical leg member extends downward perpendicular to the longitudinal axis of the needle arm. A channel is formed in the main body that enables the needle arm to rest longitudinally against the main body. A bore is also formed in the main body so that the vertical leg member may extend downward through the main body. Formed near the distal end of the main body is a pair of laterally extended wings.

Claims

1. A safety port needle assembly, comprising:

a. an elongated main body having distal and proximal ends and a longitudinally aligned channel formed therein and a bore;

b. a first pair of wings perpendicularly attached to said distal end of said main body;

c. a needle arm longitudinally aligned with said main body, said needle arm being pivotally attached at one end to the proximal end of said main body, said needle arm also including a second pair of wings enabling said needle arm to be manually lifted and rotated;

d. a port needle having a longitudinal leg and a vertical leg, said horizontal leg being attached to said needle arm and said vertical leg extending through said bore of said main body when said needle arm is longitudinally aligned over said main body, and;

e. a downward rotation limiting means located between said needle arm and said main body to prevent said needle arm from being rotated downward over said main body after being rotated upward and preventing punctures, and;

f. a pivoting arm formed on said needle arm and a lip formed on said main body which engage to prevent downward rotation of said needle arm after said needle arm is pivoted rearward.

2. The safety port needle assembly, as recited in claim 1, further including a stop surface formed on said needle arm to prevent excessive rearward rotation of said needle arm over said main body.

3. A safety port needle assembly, as recited in claim 2, wherein said channel is sufficient in size and shape to allow said needle arm to nest longitudinally inside said main body when pivoted downward over said main body.

4. A safety port needle assembly, as recited in claim 1, wherein said channel is sufficient in size and shape to allow said needle arm to nest longitudinally inside said main body.

5. A safety port needle assembly, comprised of the following:

a. an elongated main body, said main body having distal and proximal ends and a longitudinally aligned channel formed therein and a bore formed near said distal end;

b. a first pair of wings perpendicularly aligned and attached to said main body;

c. a needle arm longitudinally aligned with said main body, said needle arm being pivotally attached at one end to said proximal end of said main-body, said needle arm also including a second pair of wings enabling said needle arm to be manually lifted and pivoted rearward over said main body;

d. a port needle having a horizontal leg and a vertical leg, said horizontal leg being attached to said needle arm and said vertical leg extending through said bore of said main body when said needle arm is longitudinally aligned over said main body;

e. a stop surface formed on said needle arm to prevent excessive rearward rotation of said needle arm; and

;

f. a locking pivoting arm disposed between said needle arm and said main body which is automatically engaged to prevent downward rotation of said needle arm when said needle arm is pivoted rearward a desired distance.

6. A safety port needle assembly, as recited in claim 5, further including a gripping means attached to said needle arm to enable said needle arm to be gripped and pivoted rearward over said main body.

7. A safety port needle assembly, as recited in claim 5, wherein said channel is sufficient in size and shape to allow said needle arm to nest longitudinally inside said main body.

8. A safety port needle assembly, comprising:

a. a main body having opposite distal and proximal ends with a bore formed near said distal end;

b. a needle arm longitudinally aligned over said main body and pivotally attached at one end to said proximal end of said main body;

c. a port needle having a horizontal leg and a vertical leg, said horizontal leg being longitudinally aligned and attached to said needle arm and said vertical leg extending downward from said needle arm and through said bore on said main body when said needle arm is longitudinally aligned over said main body, and;

d. a space formed on said main body for receiving the tip of said port needle when said needle arm is pivoted rearward to remove said tip of said port needle from said bore on said main body.

9. The safety port needle assembly, as recited in claim 8, further including a lateral pair of wings attached to said main body.

10. The safety port needle assembly, as recited in claim 9, further including a pair of laterally extending wings attached to said needle arm.

11. The safety port needle assembly, as recited in claim 9, further including a stop surface formed on said needle arm to prevent excessive rearward rotation of said needle arm over said main body.

12. The safety port needle assembly, as recited in claim 9, further including a locking pivoting arm disposed between said needle arm and said main body which is automatically engaged to prevent downward rotation of said needle arm when said needle arm is pivoted rearward a desired distance.

13. The safety port needle assembly, as recited in claim 9, wherein said main body includes a longitudinally aligned channel in which said needle arm may nest when longitudinally aligned over said main body.

14. The safety port needle assembly, as recited in claim 8, further including a pair of laterally extending wings attached to said needle arm.

15. The safety port needle assembly, as recited in claim 8, further including a stop surface formed on said needle arm to prevent excessive rearward rotation of said needle arm over said main body.

16. The safety port needle assembly, as recited in claim 8, further including a locking pivoting arm disposed between said needle arm and said main body, said locking pivoting arm capable of being automatically engaged to prevent downward rotation of said needle arm when said needle arm is pivoted rearward a desired distance.

17. The safety port needle assembly, as recited in claim 8, wherein said main body includes a longitudinally aligned channel in which said needle arm may nest when said needle arm is longitudinally aligned over said main body.
