Patent number: 7458954Abstract: In some arrangements, a medical needle shield apparatus can include a binding member disposed within a shield. The binding member can include a retainer that can engaged a medical needle to prevent inclination of the binding member, and can include one or more drag inducing members that can engage the needle. In some arrangements, the apparatus can include a hub retainer.Type: GrantFiled: September 11, 2003Date of Patent: December 2, 2008Assignee: Specialized Health Products, Inc.Inventors: F. Mark Ferguson, David L. Thorne, Donald D. Solomon, Daniel K. Smith, Jeremy W. Snow, B. Chance Bagley, Craig N. Thome

Patent number: 7341573Abstract: A medical needle shield apparatus is provided that includes a needle hub having an outer needle cannula extending therefrom. An inner needle is disposed for slidable movement with the outer needle cannula. At least one shield is extensible from a retracted position to an extended position to enclose a distal end of the inner 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 binding member further includes a needle communicating surface extending therefrom that is engageable with the inner needle to prevent rotation of the binding member.Type: GrantFiled: June 24, 2004Date of Patent: March 11, 2008Assignee: Specialized Health Products Inc.Inventors: F.

Patent number: 7004927Abstract: A medical needle shield apparatus is provided that includes a shield that is extensible from a retracted position to an extended position to enclose a distal end of a needle. A binding member is disposed within the shield and defines binding surfaces that form an aperture configured for slidable receipt of the needle between the retracted position and the extended position. The binding member includes at least one drag-inducing member extending therefrom that is configured for slidable engagement with the needle between the retracted position and the extended position such that the at least one drag-inducing member engages the needle to create a drag force with the needle. The drag force causes rotation of the binding member relative to a longitudinal axis of the needle such that the binding surfaces engage the needle to prevent slidable movement of the needle in the extended position of the shield.Type: GrantFiled: December 17, 2002Date of Patent: February 28, 2006Assignee: Specialized Health Products, Inc.Inventors: F.

Patent number: 6358265Abstract: Three embodiments of a single-step lancet are disclosed. Each such lancet embodiment provides true one-step operation. In a single operational step requiring only a unidirectional displacement of an actuator into a housing, a lancet blade is removed from an aseptic environment which protects and retains the lancet blade in a pre-sterilized state within the housing prior to use, stores energy in an energy storage medium, activates the lancet blade to perform a lance and for safety retracts the lancet blade into the housing.Type: GrantFiled: July 18, 2000Date of Patent: March 19, 2002Assignee: Specialized Health Products, Inc.Inventors: Gale H. Thorne, Jr., Michael A. Wilson, Charles V. Owen, David L. Thorne, B. Chance Bagley
