RFID tag enabled shield assembly
The present invention relates to an RDID tag enabled shield assembly that provides a sterile enclosure of a medicament delivery port of a medicament container. The container can be a needleless pre-filled syringe, a vial, a cartridge, or a collapsible bag or pouch. The RFID tag is fixedly attached to one or more components of the shield assembly through co-molding or another form of permanent or removable attachment. The present invention also relates to a method of tracking the life cycle of a medicament container or a medicament injection device where the RFID tag enabled shield assembly attached to the medicament container. Data is written to or read from the RFID tag during the entire life cycle of the medicament container or injection device, including assembly, packaging, storing, distribution and use.
1. A shield assembly for providing a sterile enclosure of a medicament delivery port of a medicament container, the shield assembly comprising:
a flexible component directly connected to the medicament delivery port to form a sterile and liquid seal with the medicament delivery port;
a less flexible component securely attached to the flexible component such that rotational or axial movement of the less flexible component relative to the medicament container causes the flexible component to unseal the medicament delivery port; and
an RFID tag fixedly attached to one of the flexible component and the less flexible component, where the RFID contains data evidencing siliconization, medicament filling, shipping, quality control testing, or warehousing of the medicament container before the medicament container is incorporated into the medicament delivery device,
wherein the shield assembly is attached directly to the medicament container prior to the shield assembly and the medicament container being incorporated into a medicament delivery device such that the data is read from or written to the RFID tag before the medicament container is assembled within the medicament delivery device,
wherein once the medicament container is incorporated into the medicament delivery device the RFID tag communicates with a second RFID tag fixedly attached to the medicament delivery device.
2. The shield assembly of claim 1 where the RFID tag is a read-write tag.
3. The shield assembly of claim 2 where the RFID tag further comprises a read-only memory that contains product identification data.
4. The shield assembly of claim 1 wherein the less flexible component comprises removable first and second parts, where the second part is fixedly attached to the medicament container and the first part is fixedly attached to the flexible component such that axial movement of first part relative to the second part causes axial movement of the flexible component.
5. The shield assembly of claim 4 where the RFID tag is fixedly attached to the first part.
6. The shield assembly of claim 4 where the RFID tag is fixedly attached to the second part.
7. The shield assembly of claim 4 where the RFID tag is fixedly attached to the flexible component.
8. The shield assembly of claim 4 where the first and second parts are connected through a reversible connector selected from the group consisting of a threaded connection, a bayonet connection, press friction fit and combination thereof.
9. The shield assembly of claim 1 where the RFID tag is fixedly attached by one of a snap fit, an inlay, co-molded, an adhesive, lamination, taped, a press fit or a combination thereof.
10. The shield assembly of claim 1 further comprising an antenna in electrical communication with the RFID tag.
11. The shield assembly of claim 1 forming part of an assembly comprising a syringe that does not contain a needle and has a tapered proximal end terminating in the medicament delivery port.
12. The shield assembly of claim 1 forming part of an assembly comprising a vial having a neck portion where the shield assembly further comprises an irreversible snap connector attached to the neck portion and the flexible portion further comprises a sealing plug configured to seal the medicament delivery port.
13. The shield assembly of claim 12 further, wherein the RFID tag comprises data that is written or read during warehousing or shipping of the medicament container or the injection device.
14. The shield assembly of claim 1 forming part of an assembly comprising a collapsible medicament container having a proximal end that is fixedly attached to the shield assembly such that the flexible component forms a seal with the medicament deliver port.
15. A shield assembly for providing a sterile enclosure of a medicament delivery port of a medicament container, the shield assembly comprising:
a flexible component configured to form a sterile and liquid seal with the medicament delivery port;
a less flexible component securely attached to the flexible component such that rotational or axial movement of the less flexible component relative to the medicament container causes the flexible component to unseal the medicament delivery port; and
an RFID tag fixedly attached to one of the flexible component and the less flexible component,
wherein the shield assembly forms part of an assembly comprising a vial having a neck portion, where the shield assembly further comprises an irreversible snap connector attached to the neck portion and the flexible portion further comprises a sealing plug configured to seal the medicament delivery port.
