Abstract:
1. A sharp cutting object disposal device comprising: means for unscrewing venopuncture needles from syringes; a first container containing said unscrewing means; a second container disposed against said first container for storing syringes; a drawer disposed within said first container for storing needle waste; a gas exhaust system disposed within said first container, said exhaust system including a ventilator, an activated carbon filter on an upper part of said first container, and a hole for receiving sharp cutting objects; a pair of shafts rotatably disposed within said first container, each shaft including a contact and a brush; a first tube or chimney vertically disposed within said first container, said tube being disposed above said contacts for exhausting gases produced by melting said needle waste; a second tube being formed by two complementary tube parts disposed at a 45° angle to said first tube, said second tube directing said needles to said contacts; said second tube parts comprising a helical shaped track or rail, said track being entirely disposed on inner sides of said second tube parts; a cylindrical part disposed within said second tube, said cylindrical part being axially movable along said track or rail; an inside of said cylindrical part including two metallic parts forming a “Y” shape, said metallic parts sliding radially against said cylindrical part, said cylindrical part including two springs for biasing said metallic parts radially outward, said cylindrical part moving axially downward and rotating inside said second tube responsive to biasing from said syringes and communication of said cylindrical part with said track, said needles unscrewing from said syringes responsive to said cylindrical part moving axially downward; said second tube having first and second openings disposed at a lower part of said second tube; said metallic parts having radially inward and outward ends, said radially inward ends being adjacently disposed and said outward ends defining projecting lugs, each lug being outwardly movable through respective of said first and second openings responsive to biasing from said springs for defining an axially bottommost position of said cylindrical part in said second tube, said needles being unscrewed and separable from said syringes when said cylindrical part is disposed at said axially bottommost position; and said second tube further comprising an axially disposed spring, said axial spring biasing said cylindrical part axially upward from said axially bottommost position to a topmost position upon removal of said syringes from said second tube.
