A medication delivery pen having a magnifier, a spring biased leadscrew and a mechanism to allow the user to easily reset the dose on the medication delivery pen if the user requires a smaller dose than has been set.

Medication delivery pen

A pen needle magazine dispenser for holding and dispensing a novel pen needle assembly. The pen needle magazine dispenser includes a number of threaded sleeves within cavities that interact with threads on each pen needle assembly to attach the pen needle to a special adapter on a conventional medication delivery pen. The magazine dispenser includes a sterility barrier and a cap to cover the pen needles.

Pen needle magazine

A pen needle of the present invention includes an extender that is rotatably attached to a hub on the pen needle to set the pen needle to a desired injection length. The extender is rotated into multiple predefined positions using a shield that is removably mounted on the pen needle. Each predefined position for the extender corresponds to a predetermined injection length for the pen needle such that the extender covers a section of the pen needle not being used for the injection. After the shield has been used to rotate the extender into one of the predefined positions the shield is removed from the pen needle to expose the distal point of the pen needle so that the injection can be performed.

Adjustable injection length pen needle

A disposable pen needle assembly is provided that includes a snap lock feature that provides a user with a simple method of detaching and attaching the pen needle to the medication delivery pen. In addition, the pen needle assembly includes a multi-use shield that initially shields the distal end of the pen needle prior to use and then both shields the proximal end of the needle and locks the used needle in its outer cover prior to disposal.

Disposable pen needle

A pen needle having a cylindrical hub including a distal section that is received in a needle holder and a proximal section having threads that mate with a pair of lugs in an adaptor mounted on a medication delivery pen. The distal end of the pen needle includes a plurality of splines that mate with splines in the needle holder to prevent the pen needle from rotating within the needle holder and aid in threading the pen needle onto the adaptor. The pen needle is fully received in the needle holder to shield the proximal point of the pen needle and can only be removed from the needle holder by using the adaptor or a cartridge retainer having the proper pair of lugs thereon.

Pen needle assembly

A pen needle dispenser having a cover rotatably mounted on a circular shaped container having a plurality of cavities, with each cavity dimensioned to receive a pen needle assembly with or without shields. The cover includes a slot that is rotated into alignment with one of the cavities in the container to provide the user with access to one unused shielded pen needle and thereby permits the pen needle to be mounted on a medication delivery pen. After use the used unshielded pen needle is returned to and locked in the cavity. Then, the cover is rotated until the slot is aligned with another cavity containing the next unused shielded pen needle to be used during the next injection. The pen needle dispenser prevents the cover from rotating the slot back to cavities containing used pen needles.

Pen needle dispenser

A pen needle magazine dispenser designed to be received and carried in a cap of a medication delivery pen. The dispenser having a cover rotatably mounted on a circular shaped container with a plurality of cavities, wherein each cavity is dimensioned to receive one pen needle. The pen needle being of a type that is forced fit into an adaptor on the pen using threads on the pen needle and corresponding threads in the cavity. The cover includes a slot that is rotated into alignment with one of the cavities in the container to provide the user with access to one unused pen needle and thereby permit the pen needle to be mounted on the pen. After use the used pen needle is returned to the cavity and the cover is rotated until the slot is aligned with another cavity containing the next unused pen needle to be used during the next injection.
