  • Delivery device for injectable materials
    Patent number: 5540657
    Abstract: The invention pertains to a delivery device for controlling the injection of discrete quantities of fluid injectable materials through a conduit such as a hypodermic needle or a catheter. The delivery device is coupled to a pressurized driving fluid source, and the control means provides controlled passage of pressurized driving fluid into a syringe body to act against a piston which forces the fluid injectable material out the needle or catheter.In addition to the delivery device, the invention includes a needle depth guide which is preferably used in combination with the delivery device for cosmetic applications when a hypodermic needle is used to deliver a fluid injectable material to the dermis.

  • Hypodermic needle cannula guard
    Patent number: 5171303
    Abstract: A hypodermic needle cannula guard adapted to receive the cannula through an open slot and labyrinth passage into the interior of the guard or through a closed slit which the hypodermic needle cannula can enter through, the slit reclosing after passage of the cannula into the guard. The labyrinth passage inhibits exit of the cannula from the guard upon entry and the closed slit effectively encapsulates the cannula once it is entered into the guard. After entry of the cannula into the interior of the guard, the guard is pushed towards the hub of the hypodermic needle until the entry end of the guard and the hub of the needle are engaged and to secure the guard to the hypodermic needle.
