Abstract
A needle protective housing used to cover a contaminated needle after use is configured to have at least one cam positioned below the lip of the sheath attached to the base of the needle device for covering the needle prior to use. When the sheath is attached to the base of the needle device, the needle protective housing is positioned in proximity to the sheath. To remove the sheath, a user would pivotally move the needle protective housing in a direction away from the sheath so that the cam coacts against the lip of the sheath in an upward direction as the needle protective housing is pivoted downwards relative to the needle device. The cam may be an integral extension of the needle protective housing, or it may be a clip retrofittable to the needle protective housing.
Claims17
Apparatus comprising:
- a base with a needle end to which a needle extends, a needle protective housing having a back wall and two side walls each extending from the back wall pivotably connected to said base, a sheath non-fixedly mated to said base to cover the needle extending therefrom prior to use thereof, said sheath having an open end that frictionally contacts said base so as not to be removable from said base without a predetermined force applied thereto longitudinally along the axis of said base or needle to remove it from said base, said sheath having a circumferential lip at its open end, wherein said housing comprises finger means that are positioned below the lip of said sheath with said housing being in a first position in relative proximity to said sheath when said sheath is mated to said base and covers the needle, wherein said finger means comprises two cams each extending from a corresponding one of the side walls of said housing, each of said cams having a finger positioned below the lip of said sheath when said housing is at said first position, the finger of each of said cams pushing against the lip of said sheath to remove said sheath from said base when said housing is pivotally moved from said first position in a direction away from the longitudinal axis of said base or needle toward a second position.
Apparatus comprising:
- a base with a needle end to which a needle extends, a needle protective housing pivotably connected to said base, a sheath non-fixedly mated to said base to cover the needle extending therefrom prior to use thereof, said sheath having an open end that frictionally contacts said base so as not to be removable from said base without a predetermined force applied thereto longitudinally along the axis of said base or needle to remove it from said base, said sheath having a circumferential lip at its open end, wherein said housing comprises a back wall and two side walls extending from said back wall, wherein said housing comprises finger means that are positioned below the lip of said sheath with said housing being in a first position in relative proximity to said sheath when said sheath is mated to said base and covers the needle, said finger means applying at least the predetermined force against the lip of said sheath to remove said sheath from said base when said housing is pivotally moved from said first position in a direction away from the longitudinal axis of said base or needle toward a second position, and wherein said finger means comprises a clip separate from said housing but configured to conform with at least the lower portion of said housing so that said clip is attachable to said housing, said clip having at least one cam having a finger positioned below the lip of said sheath when said clip is attached to said housing for pushing against the lip of said sheath to remove said sheath from said base when said housing is pivotally moved toward said second position.
Needle assembly comprising:
- a base with a needle end to which a needle extends and a receptacle end adapted to connect the needle assembly to a luer of a syringe, a needle protective housing having a back wall and two side walls each extending from said back wall pivotably connected to said base, a sheath non-fixedly mated to said base to cover the needle extending therefrom prior to use thereof, said sheath having an open end that frictionally contacts said base so as not to be removable from said base without a predetermined force applied thereto longitudinally along the axis of said base toward the needle to remove it from said base, wherein said housing comprises two cams each extending from a corresponding one of the side walls of said housing, each of said cams having a finger positioned below a lip at the open end of said sheath when said housing is at said first position in relative proximity to said sheath when said sheath is mated to said base and covers the needle, the finger of each of said cams pushing against the lip of said sheath with at least the predetermined force against said sheath to remove said sheath from said base when said housing is pivotally moved from said first position toward a second position away from the longitudinal axis of said base.
Needle assembly comprising:
- a base with a needle end to which a needle extends and a receptacle end adapted to connect the needle assembly to a luer of a syringe, a needle protective housing having a back wall and two side walls pivotably connected to said base, a sheath non-fixedly mated to said base to cover the needle extending therefrom prior to use thereof, said sheath having an open end that frictionally contacts said base so as not to be removable from said base without a predetermined force applied thereto longitudinally along the axis of said base toward the needle to remove it from said base, wherein said housing being in a first position in relative proximity to said sheath when said sheath is mated to said base and covers the needle, said housing pivotable from said first position toward a second position away from the longitudinal axis of said base, wherein said needle assembly further comprising a clip separate from said housing but configured to conform with at least the lower portion of said housing so that said clip is attachable to at least a portion of said housing, said clip having at least one cam positioned below a lip that form the open end of said sheath when said clip is attached to said housing for removing said sheath from said base when said housing is pivotally moved toward said second position.
Device for removing a sheath from a needle assembly having a base to which said sheath is removably mated, the sheath covering a needle extending from said base, said sheath having an open end that frictionally contacts said base so as not to be removable from said base without a predetermined force applied thereto longitudinally along the axis of said base toward the needle, said sheath having a circumferential lip at its open end, the device comprising:
- a one piece needle protective housing pivotably connected to said base having two cams each extending from a corresponding side wall of said housing positioned below the lip of said sheath with said housing being in a first position in relative proximity to said sheath when said sheath is mated to said base and covers the needle, each of said cams having a finger that pushes against the lip at the open end of said sheath to remove said sheath from said base when said housing is pivotally moved from said first position toward a second position away from the longitudinal axis of said base.
Device for removing a sheath from a needle assembly having a base to which said sheath is removably mated, the sheath covering a needle extending from said base, said sheath having an open end that frictionally contacts said base so as not to be removable from said base without a predetermined force applied thereto longitudinally along the axis of said base toward the needle, said sheath having a circumferential lip at its open end, the device comprising:
- a needle protective housing having a back wall and two side walls pivotably connected to said base, said housing being in a first position in relative proximity to said sheath when said sheath is mated to said base and covers the needle;
- wherein said device further comprising a clip separate from said housing but configured to conform with at least the lower portion of said housing so that said clip is attachable to said housing, said clip having the at least one cam positioned below the lip of said sheath when said clip is attached to said housing for pushing against the lip of said sheath to remove said sheath from said base when said housing is pivotally moved away from the first position.
