  • Patent number: 8403004
    Abstract: A variable flow rate controller is provided herein. The controller may have a linearly traversable switch such that the controller is primed to flush air bubbles out of the fluid system of the controller prior to administering fluidic medication to a patient. Moreover, the controller may have a plurality of valves which may be independently opened and closed by a caming surface. To close the valve, a first seal may be disposed between offset inlet and outlet to prevent fluid from flowing from the inlet to the outlet. To open the valve, the first seal is disposed on one side of both of the inlet and outlet. Fluid if permitted to flow from the inlet to the outlet.

  • Patent number: 6918894
    Abstract: A safety needle device for protecting a user against a needle-stick injury. This needle device includes a needle housing having a distal housing opening. A needle is disposed within the needle housing and has a distal needle portion which extends away therefrom through the distal housing opening. An elongate sheath assembly surrounds the needle within the needle housing. A trigger member retains the sheath assembly within the needle housing against a force urging the sheath assembly towards the distal housing opening. The trigger member is sized and configured to release the sheath assembly from retention to allow the sheath assembly to transition towards and out of the distal housing opening via the force. This causes the sheath assembly to enclose the distal needle portion and protect the user against the needle stick injury.

  • Patent number: 6878136
    Abstract: A safety needle device for protecting a user against inadvertent needle-stick injury. This needle device includes a needle housing having a distal housing opening. An arcuate groove extends within the needle housing terminating adjacent the distal housing opening. A needle is disposed within the arcuate groove having a distal needle portion extending away from the needle housing through the distal housing opening. An elongate sheath assembly surrounds the needle within the groove. A biasing member is disposed within the needle housing and is configured to move the sheath assembly throughout the length of the arcuate groove and through the distal housing opening. The sheath assembly then completely enclose the distal needle portion.
