  • Patent number: 5957887
    Abstract: A medical catheter device that has a housing containing a needle and needle hub that are movable between a retracted position where the needle is safely within the protection of the housing and an extended position where the needle extends from the housing for insertion into a patient. After use, the needle can be moved to its retracted position to protect the user from inadvertent sticks from the needle. At the distal end of the catheter housing, there is a hub support having a through hole through which the needle extends when in its extended position. A flexible hollow trunk extends proximally from the through hole back into the housing and through which the needle passes. When the needle is withdrawn into its retracted position, the needle is physically caused to be moved off center so as to not realign with the through hole, however, the needle end remains encased within the flexible hollow trunk to prevent blood from entering the through hole into the interior of the housing.

  • Patent number: 5951523
    Abstract: A medical device includes a hollow needle for piercing the skin of a patient. Prior to use, the needle is located in a needle protected position within a housing. The needle can be moved outwardly from the needle protected position to an extended position where it is ready for use with the patient. After use, the needle is retracted back into the housing to the needle protected position. A door is positioned at the distal end of the housing and has an aperture. The door is slidable between a first position where the needle is in alignment with the aperture in the door so that the needle can pass through the aperture to be moved to its extended position and a second position where the needle does not line up with the aperture and thus the needle cannot be moved from the needle protected position to the needle extended position.

  • Patent number: 5951515
    Abstract: A side button is located at the distal end of a housing forming part of an I.V. catheter and which is movable between a first position to allow longitudinal movement of a needle ands a second position preventing movement of the needle. The side button is provided with a latching member which prevents release of a cannula assembly from its hub support unless the needle is fully retracted within the housing and the side button is in its second position.

  • Patent number: 5879331
    Abstract: A medical device includes a hollow needle having a distal tip for piercing the skin of a patient. A housing is provided for moving the needle relative to said housing between a first ready-for-use position and a second retracted needle protected position. A resilient arm is attached to the housing, said arm having a free end which in the second retracted needle protected position of the needle, engages said needle to move said distal tip laterally.

  • Patent number: 5846227
    Abstract: A catheter assembly includes a hollow needle having a sharpened distal tip which is movable between a position in which the needle is located within a housing and a patient penetrating position in which the distal tip extends beyond the distal end of a catheter. The catheter and a catheter hub form a catheter assembly which is supported on a catheter hub support.The catheter hub support is a one-piece molding and includes a gaskets and means that wipe the outside of the needle when the needle is withdrawn from the patient back within the housing to a needle protected position. The function of gasket means is to retard the flow of blood between the catheter hub and the catheter hub support.
