Abstract A hand held device is provided which permits safe removal of used blades from scalpels or the like in which a slotted blade is received in opposed lateral grooves in a thin elongate tang with a proximal region of the blade located behind the tang in a cut-away laterally convergent region intermediate the tang and the handle. The device includes a base wall over whose surface the scalpel is advanced and having laterally opposed protuberant regions over which the blade slides. A slot between the protuberant regions which receives the tang but not the blade. A fully inserted position of the scalpel is defined by abutment between the proximal edges of the protuberant regions and said convergent region. A rear wall is supported behind the slot with its lower edge spaced from the base wall to allow the scalpel and blade to be inserted therebetween and to allow a fully inserted scalpel to be pivoted about the lower edge to a tilted orientation in which the proximal end of the blade is levered away from the intermediate region clear of the tang and is retained by interference with the rear wall during removal of the scalpel handle in the tilted orientation. Guide surfaces proximally of the slot direct the scalpel blade or handle into the slot.
A device for removing a detachable blade from a scalpel or the like in which a slotted blade is received in opposed lateral grooves in a thin elongate tang with a proximal region of the blade located behind the tang in a cut-away laterally convergent region intermediate the tang and the handle, the device including a base wall over whose surface the scalpel is advanced and having laterally opposed protuberant regions over which the blade slides and a slot between the protuberant regions which can receive the tang but not the blade, a fully inserted position of the scalpel being defined by abutment between the proximal edges of the protuberant regions and said convergent region, a rear wall supported behind the slot with its lower edge spaced from the base wall to allow the scalpel and blade to be inserted therebetween and to allow a fully inserted scalpel to be pivoted about the lower edge to a tilted orientation in which the proximal end of the blade is levered away from the intermediate region clear of the tang and is retained by interference with the rear wall during removal of the scalpel handle in the titled orientation, and guide surfaces proximally of the slot for directing the scalpel blade or handle into the slot.
