Abstract

A contamination resistant connector for medical tubing includes a first portion with a first fluid passage therethrough occluded by a covered normally closed first valve and a second portion with a second fluid passage therethrough. The second portion is conjugate to and releasably attachable to the first portion with the second fluid passage also being occluded by a covered normally closed second valve. The first valve and the second valve are both only uncovered and opened so that the first fluid passage and the second fluid passage are fluidly communicatively connected, and closed and covered by the respective selective conjugate engagement and disengagement of the first portion and the second portion.

Claims

1. A contamination resistant connector for medical tubing comprising:

a first portion with a first fluid passage therethrough occluded by a normally closed first valve having a retractable cover thereover;

a second portion with a second fluid passage therethrough, said second portion being conjugate to and releasably attachable to said first portion, said second fluid passage being occluded by a normally closed second valve having a retractable cover thereover; and

wherein said first valve and said second valve both only being uncovered and opened so that said first fluid passage and said second fluid passage are fluidly communicatively connected and, disconnected, closed and covered by the respective selective conjugate engagement and disengagement of said first portion and said second portion.

2. The contamination resistant connector of claim 1 wherein said first portion has a latch for releasably engaging said second portion, said latch serving to releasably retain said first portion to said second portion.

3. The contamination resistant connector of claim 2 wherein said latch is coupled to said normally closed valve in said first portion so that as said latch is releasably engaged with said second portion, said first valve in said first portion is advanced into said second portion to engage said second valve thereby opening said second valve to establish a fluid tight communication between said passageway in said first portion and said passageway in said second portion.

4. The contamination resistant connector of claim 3 wherein said first valve in said first portion further comprises a pusher to facilitate said advancement of said first valve into said second portion when said first portion is engaged with said second portion.

5. The contamination resistant connector of claim 4 wherein said first portion includes a retractable first cover and said second portion includes a retractable second cover, said covers substantially preventing access to said valves when said first portion and said second portion are disengaged, said covers being retracted from said valves when said first portion and said second portion are engaged.

6. The contamination resistant connector of claim 5 wherein said first portion includes a first outward projection and said second portion includes a second outward projection, said first projection being disposed to engage said retractable second cover on said second portion and said second outward projection being disposed to engage said first retractable cover on said first portion when said first portion and said second portion are releasably engaged.

7. The contamination resistant connector of claim 6 wherein said first outward projection and said second outward projection each include a protuberance that respectively each releasably engage a receptacle on each of said first retractable cover and said second cover.

8. The contamination resistant connector of claim 7 wherein said first retractable cover and said second retractable cover each are slidably disposed to move from a closed position, wherein said first valve and said second valve respectively are covered when said first portion and said second portion are not engaged, to an open position, when said first portion and said second portion are engaged by said engagement of each of said protuberances with each of said receptacles respectively, wherein a movement of said first portion toward said second portion, as said portions are releasably engaged, urges a sliding motion of each of said covers to said open position, respectively, thereby to uncover each of said valves and, wherein a movement of said first portion away from said second portion, to releasably disengage said first portion from said second portion, urges a sliding motion of each of said covers to said closed position thereby to cover each of said first valve and said second valve respectively.

9. The contamination resistant connector of claim 8 wherein said latch further includes a stop for substantially preventing said first valve from advancing beyond said first portion unless said first portion is engaged with said second portion.

10. The contamination resistant connector of claim 1 wherein said first portion and said second portion each have an attachment for substantially non-releasably attaching a medical tubing in fluid communication with said passageways.

11. The contamination resistant connector of claim 10 wherein at least one of said attachments for substantially non-releasably attaching a medical tubing further includes a removable frangible cover, said frangible cover being substantially not replaceable once removed thereby providing a tamper evidence indication.

12. The contamination resistant connector of claim 1 being sealed in a package formed from materials substantially resistant to the passage of microorganisms and exposed to conditions that render any microorganisms therein substantially nonviable.

13. A system for transmitting a fluid between a fluid handling device and a patient comprising:

a fluid handling device having a tubing attachment and a tubing for delivering and receiving a fluid between said device and the patient;

a contamination resistant connector for connecting said tubing to an implantable device, the connector comprising;

a first portion with a first fluid passage therethrough occluded by a normally closed first valve having a retractable cover;

a second portion with a second fluid passage therethrough, said second portion being conjugate to and releasably attachable to said first portion, said second fluid passage being occluded by a normally closed second valve having a retractable cover; and

wherein said first valve and said second valve both only being uncovered and opened so that said first fluid passage and said second fluid passage are fluidly communicatively connected, and disconnected, closed and covered by the respective selective conjugate engagement and disengagement of said first portion and said second portion.

14. The system of claim 13 wherein at least one of said fluid handling device, said tubing attachment, said tubing, said implantable medical device, and said contamination resistant connector further comprises a tamper evident cover.
