Abstract
A needle shield puller has a deformable tubular body including a proximal end having a proximal opening and a distal end. An opening extends from the proximal opening toward the distal end. The opening is shaped to accommodate a portion of a needle shield. The body has initial and tension states and the opening diameter is greater in the initial state. A cinch is secured to the body at the proximal opening to secure the needle shield puller to the needle shield. The cinch biases the cinch diameter to a relaxed cinch diameter less than the needle shield diameter. A handle at a distal end of the body allows a user to place the body in the tension state. An installation aid comprises an arm releasably engageable with the cinch and the proximal opening to expand the cinch diameter toward a maximum cinch diameter greater than the needle shield diameter.

21. A needle shield puller for removing a needle shield having a needle shield diameter from a syringe having a needle and a longitudinal axis, the needle shield puller comprising:
-
a deformable, generally tubular body having a proximal end with a proximal opening, a distal end, and an opening extending from the proximal opening toward the distal end, the opening having an opening diameter and being shaped to accommodate at least a portion of the needle shield, the body having an initial state and a tension state, the body being configured such that the opening diameter is greater in the initial state than in the tension state; a cinch secured to the body at the proximal opening to secure the needle shield puller to the needle shield in a mounted configuration, the cinch having a cinch diameter, the cinch biasing the cinch diameter to a relaxed cinch diameter, the relaxed cinch diameter being less than the needle shield diameter; a handle at a distal end of the body, the handle being graspable to allow a user to exert a tensile force on the body and place the body in the tension state; and an installation aid comprising an arm releasably engageable with the cinch and the proximal opening, the arm has a generally L-shape, the installation aid graspable by the user for pulling in a direction radially away from the longitudinal axis in a mounted configuration to expand the cinch diameter so that the cinch diameter is greater than the relaxed cinch diameter and the needle shield diameter. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 32, 33, 37, 38, 39, 40)

30. A needle shield puller for removing a needle shield having a needle shield diameter from a syringe having a needle and a longitudinal axis, the needle shield puller comprising:
-
a deformable, generally tubular body having a proximal end with a proximal opening, a distal end, and an opening extending from the proximal opening toward the distal end, the opening having an opening diameter and being shaped to accommodate at least a portion of the needle shield, the body having an initial state and a tension state, the body being configured such that the opening diameter is greater in the initial state than in the tension state; a cinch secured to the body at the proximal opening to secure the needle shield puller to the needle shield in a mounted configuration, the cinch having a cinch diameter, the cinch biasing the cinch diameter to a relaxed cinch diameter, the relaxed cinch diameter being less than the needle shield diameter; a handle at a distal end of the body, the handle being graspable to allow a user to exert a tensile force on the body and place the body in the tension state; and an installation aid comprising an arm releasably engageable with the cinch and the proximal opening, wherein the proximal end of the body includes a pocket configured to receive at least a portion of the arm, the installation aid graspable by the user for pulling in a direction radially away from the longitudinal axis in a mounted configuration to expand the cinch diameter so that the cinch diameter is greater than the relaxed cinch diameter and the needle shield diameter.

31. A needle shield puller for removing a needle shield having a needle shield diameter from a syringe having a needle and a longitudinal axis, the needle shield puller comprising:
-
a deformable, generally tubular body having a proximal end with a proximal opening, a distal end, and an opening extending from the proximal opening toward the distal end, the opening having an opening diameter and being shaped to accommodate at least a portion of the needle shield, the body having an initial state and a tension state, the body being configured such that the opening diameter is greater in the initial state than in the tension state; a cinch secured to the body at the proximal opening to secure the needle shield puller to the needle shield in a mounted configuration, the cinch having a cinch diameter, the cinch biasing the cinch diameter to a relaxed cinch diameter, the relaxed cinch diameter being less than the needle shield diameter; a handle at a distal end of the body, the handle being graspable to allow a user to exert a tensile force on the body and place the body in the tension state; and an installation aid comprising an arm releasably engageable with the cinch and the proximal opening, wherein the installation aid comprises a pair of L-shaped arms releasably engageable with the cinch and the proximal end of the body, the installation aid graspable by the user for pulling in a direction radially away from the longitudinal axis in a mounted configuration to expand the cinch diameter so that the cinch diameter is greater than the relaxed cinch diameter and the needle shield diameter. - View Dependent Claims (34, 35, 36)
