A tool for removing and replacing a needle cap from a combined needle cap and needle assembly comprising a generally longitudinal wrench structure means for removing and replacing a needle cap from a needle assembly;
- said longitudinal wrench structure means defining a generally cylindrical opening having an opening axis that is perpendicular to the longitudinal wrench structure means, and further having an open top, an open bottom, and a cylindrical wall with at least one arcuate channel traversing said cylindrical wall;
- a distance between one of said first opposed arcuate channels and one of said second opposed arcuate channels is defined by an approximately 90 degrees arc;
- said generally longitudinal structure means further defines a first recess and a second recess terminating in a first wrench platform and a second wrench platform respectively;
- and additionally comprising a first ridge integrally formed on said first wrench platform and circumscribing said generally cylindrical opening, and a second ridge integrally formed on said second wrench platform and circumscribing said generally cylindrical opening.
A tool for removing and replacing a needle cap from a combined needle cap and needle assembly comprising a generally longitudinal wrench structure defining a generally cylindrical opening having a cylindrical wall with at least one arcuate channel traversing said cylindrical wall;
- said cylindrical wall has a pair of first opposed arcuate channels traversing said cylindrical wall, and a pair of second opposed arcuate channels and wherein said longitudinal wrench structure means additionally comprises a pair of opposed parallel ends having an equal length, a first arcuate end, and a second end generally perpendicular to said parallel ends and having a length less than said equal length of said parallel sides;
- wherein said first and second arcuate channels are generally equispaced from each other along said cylindrical wall;
- said generally longitudinal structure means further defines a first recess and a second recess terminating in a first wrench platform and a second wrench platform respectively;
- and comprising a first ridge integrally formed on said first wrench platform and circumscribing said generally cylindrical opening, and a second ridge integrally formed on said second wrench platform and circumscribing said generally cylindrical opening.
