  • Patent number: 7828773
    Abstract: A safety reset key is used to release a locking mechanism holding a safety shield in place over a sharp tip of a needle. In one embodiment, the reset key has ribs that are received in peripheral slots on the safety shield to engage an unlocking mechanism that unlocks a connection of the safety shield to the needle to allow the safety shield to be moved along the needle to expose the sharp tip, such as may be necessary for a second use of the needle. In another embodiment, the reset key includes a shroud that receives the shield to prevent the shield from being inadvertently pulled off of the needle when removing the key. The reset key may be associated with an obturator used to remove biological material from a central axial passageway of the needle.

  • Patent number: 7722562
    Abstract: A pump set for use with a pump to deliver a supply of liquid to a patient. The feeding set has a conduit for the nutrient liquid and a safety interlock device associated with the conduit. The pumping apparatus has a pumping device and a control system for controlling operation of the pump. An electromagnetic radiation source is operatively connected to the control system of the pump for emitting an electromagnetic radiation signal in a direction for striking the safety interlock device of the feeding set. The safety interlock device is adapted to affect the direction of the electromagnetic radiation. An electromagnetic radiation detector is operatively connected to the control system for receiving the electromagnetic radiation signal when the direction is affected by the safety interlock device, and providing an indication to the control system that the feeding set conduit is properly positioned in the feeding pump.
