Abstract
The present invention relates to an access device which is provided as part of the packaging of a blunt tip cannula or blunt tip cannula/syringe combination. The access device is preferably positioned within an elongate sheath which also protects the blunt tip cannula and which also includes an internal barrier which separates the distal end of the blunt cannula from the distal end of the access device and protects one of the access pin or blunt tip cannula from exposure or contamination while the other is being used.
Claims6
In combination, a blunt tip cannula and an access device comprising:
- a blunt tip cannula,
- an access device for pre-piercing a septum,
- a packaging device for protecting said blunt tip cannula and said access device when said blunt tip cannula and said access device are assembled therewith for storage,
- wherein at least one of said access device and said blunt tip cannula can be removed from said packaging device independently of the other of said access device and blunt tip cannula, wherein said packaging device further includes a barrier that segregates the access device from the blunt tip cannula, wherein said blunt tip cannula and said access device are oriented along a single longitudinal axis when assembled to said packaging device, and wherein said pin of said access device is removably embedded in said barrier when said access device is assembled to said packaging device.
In combination, a blunt tip cannula and an access device comprising:
- a blunt tip cannula,
- an access device for pre-piercing a septum,
- a packaging device for protecting said blunt tip cannula and said access device when said blunt tip cannula and said access device are assembled therewith for storage,
- wherein at least one of said access device and said blunt tip cannula can be removed from said packaging device independently of the other of said access device and blunt tip cannula, wherein said packaging device further includes a barrier that segregates the access device from the blunt tip cannula, and wherein said packaging device includes an interference member which prevents reassembly of said access device to said packaging device.
