Abstract

A Luer-like non-standard quick disconnect medical fluid connector that cannot be engaged with a standard Luer fitting.

Claims

1. A medical fluid connector system comprising:

a unitary male connector body defining;

an inner hollow male cone; and

an outer annular sleeve surrounding the male cone and radially spaced therefrom, the sleeve being internally threaded, the male cone extending axially beyond the sleeve, wherein

the body includes structure that prevents engaging a standard female Luer fitting with the body.

2. The system of claim 1, wherein the structure includes an outer diameter of the male cone that is greater than an outer diameter of a male cone of a standard male Luer fitting.

3. The system of claim 1, wherein the structure includes an inner diameter of the sleeve that is greater than an inner diameter of a sleeve of a standard male Luer fitting.

4. The system of claim 1, wherein the structure includes a thread pitch of the sleeve that is greater than a thread pitch of a sleeve of a standard male Luer fitting.

5. The system of claim 2, wherein the structure further includes:

an inner diameter of the sleeve that is greater than an inner diameter of a sleeve of a standard male Luer fitting; and

a thread pitch of the sleeve that is greater than a thread pitch of a sleeve of a standard male Luer fitting.

6. The system of claim 1, comprising a unitary female connector body defining:

a female cone; and

a radially elongated triangular thread external to the female cone and configured for engaging the threads of the sleeve.

7. A medical fluid connector system comprising:

a unitary female connector body defining;

a female cone; and

a radially elongated triangular thread radially beyond the female cone and configured for engaging threads of a sleeve of a male connector body.

8. The system of claim 7, comprising:

a unitary male connector body defining;

an inner hollow male cone; and

an outer annular sleeve surrounding the male cone and radially spaced therefrom, the sleeve being internally threaded for receiving the radially elongated thread of the female body, the male cone extending axially beyond the sleeve, wherein

the male body includes structure that prevents engaging a standard female Luer fitting with the body.

9. The system of claim 8, wherein the structure includes an outer diameter of the male cone that is greater than an outer diameter of a male cone of a standard male Luer fitting.

10. The system of claim 8, wherein the structure includes an inner diameter of the sleeve that is greater than an inner diameter of a sleeve of a standard male Luer fitting.

11. The system of claim 8, wherein the structure includes a thread pitch of the sleeve that is greater than a thread pitch of a sleeve of a standard male Luer fitting.

12. The system of claim 9, wherein the structure further includes:

an inner diameter of the sleeve that is greater than an inner diameter of a sleeve of a standard male Luer fitting; and

a thread pitch of the sleeve that is greater than a thread pitch of a sleeve of a standard male Luer fitting.

13. A method comprising:

providing a male connector having a central hollow male cone spaced from an annular surrounding internally threaded sleeve; and

providing a female connector having a female cone and a radially elongated triangular-shaped thread configured for engaging the sleeve, the male connector being unable to receive a standard female Luer fitting and the female connector being unable to engage a standard male Luer fitting.

14. The method of claim 13, wherein the male cone has an outer diameter that is greater than an outer diameter of a male cone of a standard male Luer fitting.

15. The method of claim 13, wherein sleeve has an inner diameter that is greater than an inner diameter of a sleeve of a standard male Luer fitting.

16. The method of claim 13, wherein the sleeve has a thread pitch that is greater than a thread pitch of a sleeve of a standard male Luer fitting.

17. The method of claim 14, wherein:

the sleeve has an inner diameter that is greater than an inner diameter of a sleeve of a standard male Luer fitting; and

the sleeve has a thread pitch that is greater than a thread pitch of a sleeve of a standard male Luer fitting.
