Definitions

  • ABSTRACT An apparatus for destroying hypodermic needles and like objects, which comprises a rotatable, cylindrical [30] Foreign Appnumon Priority Data inner cutting body, provided with a bore passing Nov. 26, I969 Sweden ..l624l/69 di metrically therethrough, at least one stationary outer cutting body which cooperates with said bore, [52] U.S.
  • the apparatus according to the invention is characterized by (a) a rotatable cylindrical inner cutting body provided with a radial through passing bore and (b) at least one stationary cutting body cooperating with said first body and provided with sharp cutting surfaces, the stationary cutting body being positioned so that two sharp cutting surfaces are located at diametrically opposed positions with respect to the cylindrical cutting body and are positioned to cooperate with its cylindrical surface and pass across the bore when the cylindrical cutting body is rotated.
  • FIG. 1 is a side view of an embodiment of the apparatus of the invention
  • FIG. 2 is an end view of the apparatus illustrated in FIG. 1,
  • FIG. 3 is a section through an outer and an inner cutting body in the apparatus illustrated in FIGS. 1 and FIG. 4 is a side view, partly cut away, of another embodiment of the apparatus according to the invention.
  • FIG. 5 is a top plan view of the apparatus illustrated in FIG. 4.
  • FIGS. 1 and 2 comprises a base plate 1 and an upper plate 2 having an opening 5, the base plate 1 and the upper plate 2 being connected together by means of two rods 3, 4, to form a frame structure in which a stationary cutting body 6 provided with sharp cutting surfaces is mounted via two fixed blocks 7, 8 which are attached to the upper plate 2 as by screws (not shown).
  • the stationary cutting body 6 is provided with a horizontal, circular through passing bore and two recesses 9 and 19 which open out into the top and lower portion of the bore so as to form sharp edges at the points of intersection between the recesses and the bore.
  • Located in the bore is a rotatable, cylindrical cutter 11, which is provided with a radially through passing bore 10.
  • the pairs of sharp edges presented by the stationary cutting body 6 are located at diametrically opposed positions with respect to the cylindrical cutter 11 and cooperate with its cylindrical surface, the sharp edges passing over the through bore 10 when the cylindrical cutter 11 is rotated.
  • the rotatable cylindrical cutter 11 is mounted in the fixed blocks 8 and 7 by means of two pins 12 and 13, respectively.
  • the pin 13 is extended outside the block 7 and is provided on the outwardly extending end with a lever 14, by means of which the cylindrical cutter II can be rotated around its symmetry axis.
  • the lever 14 is suitably biassed by means of a spring 15, which endeavors to return the cylindrical cutter 1] to a position in which a throughpassing opening is formed by the recesses 9 and I9 and the radially extending bore 10.
  • a collecting vessel 16 made for example of a plastics material, having a tightly sealing lid and partially filled with a disinfecting liquid.
  • the collecting vessel 16 is held firmly in position by means of a holder 17 which engages around a raised opening 18 in the lid and which is biassed by a spring to urge the collecting vessel 16 against the base plate I in a manner whereby the opening 18 is located beneath the recess 19.
  • the needle end of a hypodermic syringe to be destroyed is inserted down into the opening formed by the recesses 9 and 19 and the radially through passing bore 10, as shown by the chain lines in FIG.
  • the opening 5 in the upper plate 2 By giving the opening 5 in the upper plate 2 an appropriate width and by constructing the stationary cutting body in the form of a tube enclosing the rotatable, cylindrical cutter 11, and by reducing the thickness of the material around the recess 9 an apparatus is obtained in which the upper shearing position is situated very close to the point where the hypodermic needle is connected with the syringe body so that the outwardly projecting stud on which the needle is screwed to the syringe body is also sheared and thus neither the needle nor the syringe body can be reused for injection purposes.
  • the embodiment of the inventive apparatus illustrated in FIGS. 4 and 5 comprises a base plate 20 and a vertical post 21, forming a frame structure in which a cutting body 22 is secured.
  • the cutting body 22 is provided with a horizontal circular through passing bore and two recesses 23 and 24 which open out into the upper and lower portion of the bore.
  • Mounted for rotation in the bore is a rotatable cylindrical cutter 26 which is provided with a radially through passing bore 25.
  • the cylindrical cutter 26 can be rotated about its symmetry axis by means of a lever 27.
  • the lever 27 is biassed by means of a spring 28, which attempts to return the cutter 26 to a position in which a through passing opening is formed by the recesses 23 and 24 and the radial bore 25.
  • the recesses 23 and 24 Arranged in the recesses 23 and 24 are removable, stationary blades 29 and 30 which present cutting edges. As will be seen from FIG. 4, the cutting edges of the blades 29 and 30 have diametrically opposed positions with respect to the cylindrical cutter 26 and cooperate with the cylindrical surface thereof so as to pass over the bore 25 when the cylindrical cutter 26 is rotated (FIGS. 4 and 5).
  • An apparatus for destroying hypodermic needles, needle-equipped ampules, hypodermic syringes and like objects which comprises a. a rotatable, cylindrical inner cutting body, provided with a bore passing diametrically therethrough,
  • the outer cutting body being so positioned that two of its sharp cutting surfaces are located at diametrically opposed positions with respect to the inner cutting body and arranged to cooperate with the cylindrical surface thereof and relatively move across the ends of said bore upon rotation of the cylindrical cutting body.
  • the stationary outer cutting body is provided with a circular-shaped cavity and two recesses which open into the upper and lower portions of said cavity so as to thereby form sharp cutting edges at the point where the recesses intersect the cavity and the cylindrical cutting body is located in said cavity.
  • An apparatus which also includes:
  • a spring-loaded holder which is adapted to press the outer cutting body toward said raised opening whereby needles cut oil by said outer cutting body will fall through said raised opening into said collecting vessel.
  • An apparatus which includes a lever attached to said inner cutting body whereby the rotatable cylindrical cutting body can be rotated about its axis by means of a lever.
