Description

  The present invention relates to an injection needle separating apparatus for extracting an injection needle from a used syringe.

  Used syringes are dangerous because they can cause secondary infection if the person handling them accidentally touches the needle. In addition, the syringe is formed in a cylindrical shape and has a fixed internal volume made of a synthetic resin, a metal injection needle provided at the tip of the syringe main body, a synthetic resin piston main body, and It is composed of a piston with a synthetic rubber seal member provided at the tip, and when it is disposed of, it is separated into a synthetic resin part, a synthetic rubber part and a metal part from the viewpoint of waste disposal and recycling. It is preferable to discard.

  For this reason, in recent years, there has been proposed an apparatus for pulling out the injection needle from the syringe body and separating the syringe body and the injection needle. As such an apparatus, for example, an injection needle disclosed in Japanese Patent Application Laid-Open No. 2001-25493 has been proposed. There is a processing device.

  This injection needle processing device is provided with a heating unit for heating the injection needle, a guide unit for guiding the injection needle to the heating unit side, and a lower part of the heating unit. The drawing unit includes a drawing unit that pulls out, a collection box that is disposed below the drawing unit, and collects the drawn injection needle.

  The guide portion includes a circular moving member provided in a plan view so as to be movable in the vertical direction, and a guide member that engages with the moving member and guides the movement in the vertical direction. A through-hole into which the injection needle is inserted is formed through the top and bottom, and the injection needle inserted into the through-hole is formed to protrude downward. The moving member is biased upward by the spring body.

  The heating unit includes a coil having an axis line disposed vertically below the through hole of the moving member and wound at a predetermined interval from the outer peripheral surface of the injection needle, and an AC power source for supplying an AC current to the coil. The eddy current is generated in the injection needle by the alternating current flowing through the coil to generate heat.

  The pull-out portion includes a first roller having an axis horizontally disposed at a lower position of the coil and rotatably provided at the center of the axis, a drive motor, a transmission gear for transmitting the rotational force, and the like. A driving mechanism for rotating the roller about the axis, and a horizontal direction in which the axis is parallel to the axis of the first roller and the outer peripheral surface faces the outer peripheral surface of the first roller, and is rotatable about the axis and orthogonal to the axis And a second roller movably provided on the first roller and a spring body that urges the second roller toward the first roller. The drive mechanism rotates the first roller in a rotation direction corresponding to the direction of withdrawal of the injection needle. The injection needle is pulled downward by holding the injection needle between the first roller and the second roller.

  The collection box is formed with an opening at the top, and is arranged at a position below each roller so that the injection needle pulled out from the syringe body falls into the collection box.

  According to this injection needle processing apparatus, for example, in a state where an alternating current is passed through a coil by an alternating current power source and a first roller is rotated by a drive mechanism, an operator passes the injection needle of a used syringe through a moving member. When the syringe body is brought into contact with the moving member by being inserted into the hole, and the syringe body is pushed down against the urging force of the spring body together with the moving member, the syringe needle passes through the coil and passes through the first roller. And reaches the second roller and is sandwiched between the rollers.

  The injection needle generates heat due to the eddy current generated by the alternating current flowing through the coil, and the temperature rises. When this temperature rise causes the injection needle root portion to melt, the syringe main body is pulled out by the pulling action of the first roller and the second roller. Pulled out from. Then, the extracted injection needle falls into the collection box and is collected. On the other hand, the syringe main body and the moving member withdrawn from the injection needle are pushed upward by the biasing force of the spring body until the moving member returns to the original position.

Then, the syringe receiver 16 and the moving member 11 are raised to their original positions by the urging force of the compression spring 39, thus completing a series of needle extraction processes.

  When the above-described injection needle extraction process is repeated a predetermined number of times, the operator pulls out the collection box 48 from the holding member 47 and appropriately discards the extracted injection needle H in the collection box 48. . Further, when the gap formed between the swing member 21 and the receiving member 22 does not match the thickness of the injection needle H, the pair of support plates 24 and the swing member 21 are rotated by rotating the adjustment bolt 41. Is moved in the opposite direction to adjust the size of the gap (see FIG. 6).

  Thus, according to the injection needle separating apparatus 1 of the present example, the injection needle H is held between the swing member 21 and the receiving member 22 by the urging force of the compression spring 33, and the syringe body T is held by the urging force of the compression spring 39. Since the tip of the swinging member 21 is moved downward and swung downward by swinging the swinging member 21, the sandwiched injection needle H is pulled out from the syringe body T so as to be sent downward. Compared with the conventional injection needle processing apparatus provided with a drive mechanism including a drive motor and a transmission gear, the apparatus configuration can be simplified and made compact, and the manufacturing cost can be reduced.

  Moreover, since the oscillating member 21 is oscillated to hold the injection needle H, the injection needle separating apparatus 1 can be used regardless of the thickness of the injection needle H. Since the injection needle H is sent downward by swinging, the injection needle H can be more easily pulled out.

  Further, since the size of the gap formed between the swinging member 21 and the receiving member 22 can be adjusted by the adjusting bolt 41, the injection needle separating apparatus 1 can be made more compatible with various syringes. it can.

  As mentioned above, although one Embodiment of this invention was described, the specific aspect which this invention can take is not limited to this at all.

  In the above example, the injection needle H is heated by the heater 38 built in the receiving member 22. However, the present invention is not limited to this. For example, an eddy current is generated in the injection needle H by passing an alternating current through the coil. By doing so, the injection needle H may be heated. The configuration of the adjustment mechanism 40 may be any configuration as long as the gap between the swing member 21 and the receiving member 22 can be adjusted, and is not limited to the above example. The connection between the support shaft 32 and the connection member 31 is performed by forming a screw groove (not shown) in the lower end portion of the support shaft 32 and forming a screw hole (not shown) in the connection member 31. The support shaft 32 and the connection member 31 may be coupled by a screwed relationship between a screw hole (not shown) and a screw hole (not shown).
