摘要： 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.

摘要： 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.
摘要翻译：本发明涉及用于控制通过诸如皮下注射针或导管的导管注射离散量的可流动注射材料的递送装置。输送装置联接到加压的驱动流体源，并且控制装置提供加压的驱动流体受控地通向注射器主体中以作用于迫使流体可注射材料流出针或导管的活塞。除了输送装置之外，本发明还包括针深度导向器，当使用皮下注射针将流体可注射材料输送到真皮时，优选与用于化妆品应用的输送装置组合使用。
