  • Publication number: 20160331902
    Abstract: A syringe assembly is disclosed which includes a syringe body defining a fluid reservoir, a plunger assembly including a plunger rod and a sealing member supported on the plunger rod, and a luer cap releasably secured to a distal end of the syringe body. The luer cap includes a luer-type connector member and a fluid outlet. A one way valve is supported within the fluid outlet of the luer cap to prevent flow from the fluid outlet back into the fluid reservoir of the syringe body.

  • Publication number: 20140309618
    Abstract: The present disclosure relates to a safety needle assembly that includes a syringe and a safety mechanism. The safety mechanism includes a housing defining an internal cavity, a shield member at least partially disposed within the internal cavity, and first and second locking members that are configured to selectively engage and maintain the shield member in one or more predetermined positions. The locking members are movable between a locked position, in which the locking members are in engagement with the shield member to substantially prevent axial movement thereof, and a release position, in which the locking members are disengaged from the shield member to permit axial movement thereof. The first and second locking members each include biasing members. The biasing member of the each locking member is positioned to cooperate with the other locking member to normally bias the locking members towards the locked position.

  • Patent number: 7736332
    Abstract: A safety shield is provided including a piercing member having a proximal end, a distal end and defining a longitudinal axis. A clip defines a first cavity dimensioned for movement of the piercing member therethrough and is oriented in an axis transverse to the longitudinal axis. The first cavity is movable between a movable orientation and a binding orientation. The clip includes a first leg that defines a second cavity dimensioned for movement of the piercing member therethrough and a distal part being configured to engage a medical device. The clip further includes a second leg having a bearing surface that engages the piercing member. The legs are biased for convergent movement such that the first cavity is disposed in the binding orientation and the distal part of the first leg disengages the medical device.

  • Publication number: 20080082053
    Abstract: Featured is a medical infusion device for vascular access with enhanced flashback visualization that includes a hub assembly having a flashback chamber. The hub assembly includes a proximal portion, a distal portion and a substantially transparent window section intermediate the proximal portion and distal portion. A needle is coupled to the flashback chamber so that fluid flows through the lumen of the needle into the flashback chamber after the needle is inserted into a blood vessel. A contrasting member is disposed on at least a portion of the hub assembly, so that when blood enters the flashback chamber, the contrasting member provides a high-contrast background when viewed through the window section.

  • Publication number: 20080065015
    Abstract: A safety shield incorporating a locking clip to prevent inadvertent sticks or punctures by a needle is provided. The needle can be a needle cannula or other piercing member, disposed in a sliding orientation in the safety shield, such that the needle slides within the locking clip between an aperture at a proximal end of the locking clip and a trigger hole at a distal end of the clip. Upon withdrawal of the needle after use, a binding orientation is triggered when the needle tip is withdrawn from the trigger hole. As further protection to the bi-directional lock afforded by the binding orientation, the needle is provided with a safety stop to prevent movement of the needle tip through the aperture. In other aspects, the safety shield includes a trigger bushing, in which the needle cannula is slidably received, that is sized larger than the aperture.

  • Publication number: 20060189936
    Abstract: A safety shield apparatus is provided that includes a housing that defines a cavity. A distal end of the housing includes a cover having a movable tab. A hub is disposed for movement within the housing and includes a needle having a distal end and a movable projection. The hub is biased between an extended position, such that the distal end of the needle is exposed and the movable projection is releasably disposed with the cavity, and a retracted position whereby the distal end of the needle is disposed within the housing. The movable tab is engageable with the movable projection to release the movable projection from the cavity to facilitate movement of the hub. The distal end of the housing may define a lip that is configured to capture the distal end of the needle. The hub can define an angled distal surface to orient the needle out of axial alignment with the housing and into capture with the lip.

  • Publication number: 20050059936
    Abstract: A safety apparatus is provided which includes a needle hub having an arm extending therefrom and an extensible frame connected to the needle hub. The extensible frame includes a proximal segment that is hingedly connected to a distal segment. The extensible frame is resiliently biased from a retracted position to an extended position, wherein the arm releasably engages the proximal segment to fix the extensible frame in a position between the retracted position and the extended position. In an alternate embodiment, the safety apparatus includes an extensible frame including a proximal segment which is hingedly connected to a distal segment. A resilient member is coupled to the proximal segment and the distal segment. The resilient member is configured to bias the extensible frame from a retracted position to an extended position. A method for infusing fluids to a subject is disclosed.
