  • Publication number: 20150148752
    Abstract: A process for lyophilizing a solution of an active agent in a container is provided. Solution of active agent is deposited into a container, the container is covered with a covering plate and placed inside a lyophilizing apparatus. Lyophilization can be conducted to dryness by radiation, convection or both. Also provided is a device made by this process, an active agent-plastic administration device (e.g., a syringe), containing an active agent in the form of lyophilized cake, and an array of such administration devices.

  • Patent number: 6626870
    Abstract: A syringe assembly is provided which includes a hollow barrel that has an interior wall. The interior wall defines a chamber that retains medication. The hollow barrel also includes a distal end and a proximal end. The distal end of the hollow barrel has a passageway that is in contact with the chamber. The proximal end of the hollow barrel has an aperture. The syringe assembly also includes a primary plunger tip that is slidably positioned, in fluid tight engagement, with the interior wall. The primary plunger tip has a receptor to engage an engager of an elongated tip plunger rod. The syringe assembly also includes a secondary plunger tip that is slidably positioned, in fluid tight engagement, with the interior wall. The secondary plunger tip also has a receptor to engage an engager of a tip plunger rod. The secondary plunger tip is disposed between the primary plunger tip and the proximal end of the hollow barrel.

  • Patent number: 6610252
    Abstract: The present invention provides a system for lyophilization comprising one or more delivery containers, e.g. syringes, and a cover plate, which covers them during lyophilization. The cover plate includes a lid region and one or more protuberances, which project perpendicularly from the lid region and fit delivery containers such that the protuberances are not in complete and continuous contact with sidewalls of the delivery containers. The cover plate permits the escape of vapor from the delivery containers during lyophilization process through an annular gap between each protuberance and a sidewall of each container when the cover plate is resting on the top of the delivery containers. At the same the cover plate prevents the escape of lyophilizate, in particular a pharmaceutical, from the containers during lyophilization.
