Abstract: The present invention relates to medical devices, in particular autoinjectors and syringes having one or more thermochromic response indicators that are sensitive to temperature changes of a drug formulation or solution. The present invention provides for a pre-filled delivery device comprising a syringe, a cartridge, or a capsule having a barrel, where the barrel is marked on the outer surface with a first thermochromic indicator, and wherein the thermochromic indicator is responsive to temperature changes of the drug formulation or solution within the barrel.

Abstract: A collet mechanism that holds a cannula during molding of a syringe includes first and second arms that form an internal cavity. Each arm has a proximal end and a distal end. The first and second arms are in a closed position when the distal ends are moved toward the internal cavity and are in an open position when the distal ends are positioned away from the internal cavity. First and second cannula guides respectively are mounted proximate the distal ends of the first and second arms and extend into the internal cavity. The first and second cannula guides clamp a portion of the cannula to hold the cannula when the first and second arms are in the closed position.

Abstract: A gas light ignition and flame supervision system for a gas light that comprises a burner tip and a glow coil adapted to be positioned in a operational distance from the burner tip to ignite a flame when heated and to conduct a current through the flame to the tip. The tip having a metallurgy composition that allows the flame current to conduct to a ground line. The flame current on the ground line is sensed by a control unit. Thus, a flame sensor is not positioned in the interior of the gas light housing or in proximity to the flame. The system also includes a remote controller to turn on and off the system.

Abstract: An adaptor that can connect a gas cylinder to a separate gas fitting, with a high level of safety. Vents in the threaded portion allow excess pressure to be relieved before the gas cylinder is removed from the adaptor, thereby preventing unexpected release of pressure which can injure users and bystanders. An insulating outer jacket provides an easily gripped surface and prevents contact with cold surfaces caused by gas discharge. The adaptor is easy to manufacture and includes a sturdy design to withstand heavy use without breaking.
