Abstract

A method of sterile needless vial access, utilized to transfer materials from one unit to another. The method utilizes a swab-able access port and a blunt cannula. The access port receives the blunt cannula to couple and aseptically transfer medical and body fluids. The swab-able access port permits disinfectant treatment before receipt of the blunt cannula to limit and prevent contamination of sterile fluids.

Claims

1. The method of accessing a port, comprising the steps of:

(a) swabbing a movable plug positioned flush with the bore of a stopper, for which said bore extends from an entry position, where said plug is swabbed, to an exit position;

(b) moving said plug within said bore away from said entry position;

whereby communication can be established along said said bore between said entry position and said exit position.

2. The method of claim 1 for accessing a port, further comprising the step of swabbing an integral surface of said movable plug extending integrally across said bore.

3. The method of claim 1 for accessing a port, further comprising the step of:

swabbing said movable plug with respect to frangible, connections thereof to said bore.

4. The method of claim 1 for accessing a port, further comprising the step of:

slidably moving said plug along said bore.

5. The method of claim 1 for accessing a port, further comprising:

engaging said plug by a filament with a transverse gap between a portion of the exterior surface of said plug and the engagement end of said fitment.

6. The method of claim 1 for accessing a port, further comprising:

piercing said plug by a cannula.

7. The method of claim 1 for accessing a port, further comprising the step of:

engaging a collar of said stopper at said entry position of said bore.

8. The method of claim 7 for accessing a port, further comprising the step of:

engaging eternal Luer threads of said collar.

9. The method of claim 1 for accessing a port, further comprising the step of:

stretching an apertured membrane that spans said exit position of said bore.

10. The method of claim 1 for accessing a port, further comprising the step of:

causing fluid to flow in an auxiliary channel of said bore when said plug is depressed in said bore.

11. The method of accessing a port, comprising the steps of:

moving a plug to the entry position of a bore extending to an exit position of a port;

and engaging said plug at said entry position and moving said plug through said bore, further including the step of frangibly connecting said plug to said bore.

12. The method of accessing a port, comprising the steps of moving a plug to the entry position of a bore extending to an exit position of a port;

and engaging said plug at said entry position and moving said plug through said bore, further including the step of piercing said plug by a cannula with said plug seated in a stopper.

13. A method of transferring fluid from a container, comprising the steps of:

(a) positioning a stopper in a neck portion of a container having a central throughbore extending from an outer surface of said stopper to the interior of said container;

(b) extending a plug into said bore from a position sealed outer surface of said stopper; and

(c) depressing said plug to permit fluid to flow between said interior and said outer surface.

14. The method of accessing a port of a container as defined in claim 13 further including the step of extending said plug integrally across said bore to said stopper surrounding said plug.

15. The method of accessing a port of a container as defined in claim 13 further including the step of slidably connecting said plug to said bore.

16. The method of accessing a port of a container as defined in claim 13 further including the step of providing said plug with a non-planar external surface.

17. The method of accessing a port of a container as defined in claim 13 further including the step of spanning said bore with a stretchable membrane.

18. The method of accessing a port of a container as defined in claim 13 further including the step of providing said plug in said stopper with a collar.

19. The method of accessing a port of a container as defined in claim 18 further including the step of providing said collar with external Luer threads.
