Abstract
The present invention preferably comprises a method and several apparatus embodiments for needle unlocking and disengagement by a single straight-through insertion of the needle to the needle hub, twist unlocking and push through and pull back disengagement. In addition, it is preferable to adapt the relatively small "footprint" of the needle unlocking and disengagement device for placement at the end of a splash and aerosol protective cylinder whereby the external cylindrical body surface of the syringe or vacuum tube adapter lies relatively close to the inside wall of the protective cylinder upon insertion of the syringe or vacuum tube adapter for needle unlocking and disengagement.
Claims18
A needle unlocker comprising:
- two or more unlocking, downward flexure lugs extending substantially toward each other in a plane from a lug plate, wherein adjacent edges of the lugs define an aperture with an intersection spacing smaller than a needle hub top rim diameter.
A method for needle unlocking and disengagement comprising:
- (a) two or more unlocking, downward flexure lugs extending substantially toward each other in a plane from a lug plate, wherein adjacent edges of the lugs define an aperture with an intersection spacing smaller than a needle hub top rim diameter;
- (b) inserting a device-attached needle hub into the aperture;
- (c) unlocking and disengaging the needle from a device to which it is attached by twisting motion without substantial lateral motion to engage the unlocking, downward flexure lugs;
- and
- (d) pushing past adjacent edges the needle hub top rim by flexure of the unlocking, downward flexure lugs, whereby the needle is released entirely from engagement with unlocking, downward flexure lugs.
A system for needle unlocking and disengagement within a removable top for a sharps container comprising:
- (a) a needle unlocker with two or more unlocking, downward flexure lugs extending substantially toward each other in a plane from a lug plate, wherein adjacent edges of the lugs define a needle unlocking aperture with an intersection spacing smaller than a needle hub top rim diameter.
