Abstract: A needle shield remover for removing a needle shield covering a needle on a syringe includes a body having a proximal portion and a distal portion. The distal portion is moveable between a contracted configuration and an expanded configuration in response to opposite movement of the proximal portion. The distal portion includes an internal opening for receiving and at least partially surrounding a needle shield therein. An anchor extends inwardly from the distal portion into engagement with the needle shield when the distal portion is in the contracted configuration to secure the body to the needle shield. A sleeve is in fixed axial arrangement with the proximal portion of the body. The axial engagement maintains the distal portion of the body in the contracted configuration such that force applied to the sleeve away from the body removes the needle shield and body from a syringe.

Abstract: An open-close work implement is provided, wherein an object can be easily held without being damaged by a simple operation of merely gripping or squeezing the open-close operation part (5) with the fingertips. A first half member (1) and a second half member (2) are intersected and pivotally fitted together, an open-close working part (4) is provided to the distal end, and an open-close operation part (5) is provided to the proximal end.
