Medical cannula package
View Patent ↗A package for a medical cannula with a hub, such as a pen needle, is disclosed. The package includes a cover for receiving a medical cannula and for engaging a hub of the medical cannula. The cover has open ends that are in communication through the cover. The packaging also includes a sterility barrier for the cover.
1. A package, comprising:
a medical cannula having a hub, the medical cannula also having a distal end for insertion into a patient;
a cover for receiving the medical cannula and for engaging the hub of the medical cannula, the cover:
extending distally beyond the distal end of the medical cannula when the medical cannula is fully inserted therein;
having open ends that are in communication through the cover; and
having a lock-out feature for axially retaining the medical cannula after the medical cannula is inserted into the cover so that a proximal end of the hub distally bypasses the lock-out feature; and
a sterility barrier for the cover;
wherein the interior of the cover comprises a stop to prevent a medical cannula from being inserted so far into one of the open ends of the cover that a needle portion of the medical cannula presents a danger at the other open end of the cover.
2. The package according to claim 1 , wherein the interior cover shape corresponds to the shape of the medical cannula hub.
3. The package according to claim 2 , wherein the hub and the cover interior are substantially cylindrical.
4. The package according to claim 1 , wherein the stop comprises a shoulder.
5. The package according to claim 1 , wherein the sterility barrier comprises:
a removable barrier affixed to a non-patient end of the medical cannula disposed at one of the open ends of the cover; and
a fixed barrier disposed at another open end of the cover.
6. The package according to claim 1 , wherein the sterility barrier comprises:
a removable barrier affixed to one of the open ends of the cover at which a non-patient end of the medical cannula is disposed; and
a fixed barrier disposed at another open end of the cover.
7. The package according to claim 6 , wherein the removable barrier comprises:
an openable cap, comprising:
a rim affixed to the open end of the cover at which a non-patient end of the medical cannula is disposed;
a connector, connected to the rim; and
a lid, connected to the connector and securable to the rim to selectively close the packaging.
8. The package according to claim 6 , wherein the removable barrier comprises:
an openable cap, comprising:
a connector, connected to the open end of the cover at which a non-patient end of the medical cannula is disposed; and
a lid, connected with the connector and securable to the open end of the cover at which a non-patient end of the medical cannula is disposed, to selectively close the packaging.
9. The package according to claim 1 , wherein a tolerance of a fit between the hub and the cover is adapted to ensure that the proximal end of the hub bypasses the lock-out feature upon application of a force by a user to insert the medical cannula into the cover.
10. A package, comprising:
a medical cannula having a hub, the medical cannula also having a distal end for insertion into a patient;
a cover for receiving the medical cannula and for engaging the hub of the medical cannula, the cover:
extending distally beyond the distal end of the medical cannula when the medical cannula is fully inserted therein;
having open ends that are in communication through the cover; and
having a lock-out feature for axially retaining the medical cannula after the medical cannula is inserted into the cover so that a proximal end of the hub distally bypasses the lock-out feature; and
a sterility barrier for the cover, wherein the sterility barrier comprises:
a blister pack, comprising:
a blister portion for housing the cover and the medical cannula; and
a lid portion for sealing the blister portion;
wherein the interior of the cover comprises a stop to prevent a medical cannula from being inserted sufficiently far into one of the open ends of the cover that a needle portion of the medical cannula would present a danger at the other open end of the cover.
11. A package, comprising:
a medical cannula having a hub, the medical cannula also having a distal end for insertion into a patient;
a cover for receiving the medical cannula and for engaging the hub of the medical cannula, the cover:
extending distally beyond the distal end of the medical cannula when the medical cannula is fully inserted therein;
having open ends that are in communication through the cover; and
having a lock-out feature for retaining the medical cannula within the cover after the medical cannula is inserted into the cover so that a proximal end of the hub distally bypasses the lock-out feature; and
a sterility barrier for the cover, wherein the sterility barrier comprises an individually sealed wrapper;
wherein the interior of the cover comprises a stop to prevent a medical cannula from being inserted sufficiently far into one of the open ends of the cover that a needle portion of the medical cannula would present a danger at the other open end of the cover.
12. The package according to claim 11 , wherein the individually sealed wrapper comprises a shrink-wrapped barrier encasing the periphery of the cover.
13. A package, comprising:
a medical cannula having a hub, the medical cannula also having a distal end for insertion into a patient;
a cover for removably receiving the medical cannula in a first orientation and for securing therein the hub of the medical cannula, the cover:
extending distally beyond the distal end of the medical cannula when the medical cannula is fully inserted therein;
having open ends that are in communication through the cover; and
having a lock-out feature for retaining the medical cannula within the cover after the medical cannula is inserted into the cover in the first orientation so that a proximal end of the hub distally bypasses the lock-out feature; and
a sterility barrier for encasing the cover, and the medical cannula.
14. The package according to claim 13 , wherein the sterility barrier comprises:
a blister pack, comprising:
a blister portion for housing the cover and the medical cannula; and
a lid portion for sealing the blister portion.
15. The package according to claim 14 , wherein the cover is retained at least partially within the blister portion during connection and/or disconnection of a medical cannula with an injection device.
16. The package according to claim 15 , wherein the blister portion comprises an internal rib to grasp the cover to retain the cover at least partially within the blister portion during connection of the medical cannula with the injection device.
17. An array of packages according to claim 14 , wherein perforations separate at least one package in the array.
18. An array of packages according to claim 14 , wherein at least one package is individually separable from the array.
19. The package according to claim 13 , wherein the sterility barrier comprises an individually sealed wrapper.
20. An array of packages according to claim 19 , wherein the sterility barriers are longitudinally joined to form a strip.
21. The array according to claim 20 , wherein perforations separate the individual sterility barriers.
