Patent number: 9539398Abstract: A medical needle shield apparatus is provided that includes a needle hub having a needle cannula extending therefrom. At least one shield is extensible from a retracted position to an extended position to enclose a distal end of the needle. The shield includes a binding member disposed within the shield and defines binding surfaces that form an aperture configured for slidable receipt of the inner needle. The binding member includes at least one drag inducing member that engages the inner needle during slidable receipt to create a drag force. The drag force facilitates rotation of the binding member such that the binding surfaces engage the inner needle to prevent slidable movement. The shield and/or hub includes a retention element engageable between the shield and hub and a sheath retention element. The hub includes a magnifier for viewing fluid flashback.Type: GrantFiled: September 26, 2014Date of Patent: January 10, 2017Assignee: Specialized Health Products, Inc.Inventors: F. Mark Ferguson, Donald D. Solomon, Roy L. Barrus, Jeremy W. Snow

Patent number: 7198618Abstract: Medical needle shield apparatus for covering a needle after use. In embodiments of this invention a shield with two or more segments hingedly connected to each other is movable from a retracted position where the needle is exposed, to an extended position where the shield extends beyond the end of the needle. The needle is affixed in a hub of a medical needle device, and the shield is articulated to the hub. At least one of the two or more segments has an open orifice through which the needle passes to form an axis of intersection about the needle. The shield includes a channel for covering the needle when the shield is linearly extended. One or more locks associated with one or more of the segments secures one or more of the segments relative to the shield in the extended position. A latch is also disposed on the distal segment for securing the distal segment relative to the shield when in the extended position.Type: GrantFiled: June 27, 2001Date of Patent: April 3, 2007Assignee: Tyco Healthcare Group LPInventors: F.

Patent number: 6197007Abstract: Disclosure of methods and apparatus providing bases for design of compact small bore medical needle retraction safety devices wherein actuators are displaced away from slender needle sheathing bodies to initiate a needle retraction cycle for safely containing a medical needle after use. Such actuation guards against inadvertent acts, such as depression of an actuator, which may result in untimely needle retraction. Four embodiments of the instant invention are disclosed. In one embodiment, needle retracting energy is stored as a medical needle is extended for use and is expended to retract the needle into safe containment. Other embodiments comprise power assist mechanisms which store energy during an initial phase of needle retraction to be used to enhance and assist needle retraction during a needle retraction completing phase.Type: GrantFiled: February 4, 1999Date of Patent: March 6, 2001Inventors: David L. Thorne, Roy L. Barrus, Kendall P. Thorne, Gale H. Thorne

Patent number: 6063040Abstract: A practical, low cost safety device for phlebotomy. Preparation for operation of the device involves elongating an otherwise shortened-for-transport apparatus to extend a medical assembly and needle from a housing for use in a medical procedure. The act of elongating energizes an energy storing component and cocks a releasable latch. The energy storing component is preferably a vacuum drawing plunger and tube combination. When the medical procedure is complete, distortion of a portion of the housing causes powered retraction of the needle. After retraction, the needle is fully contained, permitting the device to be laid aside without fear of an inadvertent needle stick. The housing comprises a proximal barrel and a distal needle containment section. The barrel comprises a sampling tube stopper piercing cannula.Type: GrantFiled: January 16, 1998Date of Patent: May 16, 2000Assignee: Specialized Health Products, Inc.Inventors: Charles V. Owen, David L. Thorne, Gale H. Thorne, Roy L. Barrus
