Then, it is inserted into the grip portion 23 and sandwiched.

The first lever 21 is a fixing member fixed to the side wall 13 of the case 10 via a fixing tool 19, and the second lever 22 is a movable member that is rotatable with respect to the first lever 21. A compression spring that elastically urges the second lever 22 toward the first lever 21 in the separating direction between the rear portions of the first and second levers 21 and 22 to give a gripping force to the grip portion 23. 24 are provided. Further, the rear end portions of the first and second levers 21 and 22 are connected by a solenoid actuator 25, and when the solenoid actuator 25 is energized, the rod 25a thereof retracts and the rear portion of the second lever 22 moves to the first position. The 1 lever 21 rotates in a direction approaching the rear part of the lever 21, and the grip portion 23 is wide open to release the grip of the injection needle 2.

Below the injection needle 2 which is inserted and held in the grip portion 23 of the injection needle grip 20, a movable copper member which is positioned in series opposite to the injection needle 2 and contacts the lower end of the injection needle 2. The electrode 30, a cylindrical electrode holder 32 that holds the movable electrode 30 so that it can be raised and lowered, an electrode holder support base 36 that supports the electrode holder 32, and a compression spring 34 that elastically biases the movable electrode 30 upward. Is provided. As shown in FIG. 2, a slit 38 extending to near the upper end is formed on a side portion of the electrode holder 32, and a cable 49 connected to the movable electrode 30 can move up and down in the slit 38. Since the spring 34 is always urged upward, the movable electrode 30 always keeps contact with the lower end of the injection needle 2. When the upper end of the movable electrode 30 approaches the grip portion 23 with a slight gap, the metal fitting 30a on the side of the movable electrode 30 is locked by the locking portion 38a at the upper end of the slit 38, The movable electrode 30 stops.

At the front end portion of the bottom wall 15 of the case 10, a collection box 52 with an open top is provided with a handle, and the collection box 52 can be taken out forward from the opening 16 of the front wall 12 of the case 10. Is configured. A shoot 50 extending from a portion near the upper end of the electrode holder 32 to the upper end of the recovery box 52 is provided, and a pair of left and right guide plates 53 of the chute 50 is fixed to the bottom wall 15 of the case 10 to fix the chute 50. It is fixed and supported. A box-shaped accommodating portion 17 for accommodating the resistor 40 and the control box 42 is provided in the lower portion of the rear portion of the case 10, and an opening 18 for opening the right end of the accommodating portion 17 is formed in the side wall 13 of the case 10. The resistor 40 and the control box 42 are arranged so as to be able to be taken in and out of the housing portion 17.

The resistor 40 is for supplying a melting current to the injection needle 2 held in the grip portion 23 via the injection needle grip 20 and the movable electrode 30, and the resistor 40 has a cable 47. It has a rectifier that converts the power of 100 VAC supplied through the rectifier to a DC power, and an electric resistor that adjusts the DC current supplied to the injection needle 2, and the positive terminal of the resistor 40 is connected via the cable 48. It is connected to the first lever 21 of the injection needle grip 20, and the negative terminal is connected to the movable electrode 30 via the cable 49.

When the control box 42 receives an operation signal from the operation switch 44 provided on the upper wall 11 or the front wall 12 of the case 10, the control box 42 outputs a command signal for instructing the resistor 40 to be energized for a predetermined time. The melting current is supplied for a predetermined time, and after the energization is completed, the current is supplied to the solenoid actuator 25 for a predetermined set time to drive the rod 25a of the solenoid actuator 25 to retract and drive.

Next, the operation of the injection needle dissolution processing device 1 described above will be described. When the cable 47 is connected to an AC 100 volt power supply (outlet), the display lamp 46 lights up. In this state, when the doctor or nurse inserts the injection needle 2 immediately after use into the grip portion 23 facing the opening 14 to the maximum extent and holds it, the grip portion 23 of the injection needle grip 20 has a strong spring 24. Since the injection force is exerted, the injection needle 2 is strongly sandwiched and held by the grip portion 23. When the injection needle 2 is inserted, the movable electrode 30 is kept in contact with the lower end of the injection needle 2. When the injection needle 2 is stopped while being lowered against the spring 34 while maintaining the same, the movable electrode 30 is also stopped while maintaining the contact state.

Next, when the doctor or the nurse turns on the operation switch 44, the control box 42 controls the resistor 40, the cable 48, the first lever 21 of the needle grip 20, the injection needle 2, and the movable electrode 30. A melting current of a predetermined magnitude is supplied for a predetermined time to a current circuit composed of a cable 49 and a cable 49. Since the contact portion between the injection needle 2 and the movable electrode 30 has a large electric resistance, the amount of heat generated at the contact portion is maximum, so that the dissolution proceeds from the lower end of the injection needle 2 and the spring 34 moves upward in response to this. Since the movable electrode 30 biased to the ascends while maintaining the contact state with the injection needle 2, the dissolution of the injection needle 2 progresses until the movable electrode 30 comes into contact with the lower surface of the grip portion 23 and the injection is performed. Most of the needle 2 is melted, and the melted metal pieces fall from the chute 50 into the recovery box 52.

Immediately after the movable electrode 30 comes close to the lower surface of the grip portion 23 and stops, the energization is cut off after a lapse of a predetermined time, and then the solenoid actuator 25 is energized for a set time so that the rod 25a thereof is As it retreats, the grip portion 23 opens and the gripped portion 2b of the injection needle 2 and the large-diameter portion 2a at the upper end (see FIG. 2) fall from the chute 50 into the collection box 52. After the lapse of the set time, the solenoid actuator 25 is de-energized, so that the grip portion 23 is closed again and waits for the next injection needle 2. The dissolution treatment of one injection needle 2 is performed as described above. In this way, when the used injection needle 2 is removed from the syringe after use, the used injection needle 2 is immediately inserted into the grip portion 23 and the operation switch 44 is operated. Since it can be easily and surely lysed, it is possible to reliably prevent the accidental use of the used injection needle 2 in the hand, finger, etc. to infect pathogenic bacteria attached to the injection needle 2. it can.

Next, a modified example in which a part of the above embodiment is modified will be described. 1) As shown in FIG. 3, a concave portion 26 that can hold the large diameter portion 2a of the injection needle 2 is formed in the grip portion 23 of the injection needle grip 20, and the large diameter portion 2a and the needle portion near the lower side thereof are formed. It is configured to sandwich. With this structure, almost the entire needle portion of the injection needle 2 can be surely dissolved. 2) The above-mentioned embodiment is an injection needle dissolution processing apparatus for dissolving and processing one injection needle 2, and is suitable for use by being installed near an examination site of an individual doctor. However, it is needless to say that the injection needle grip 20 may be provided with a plurality of grip portions 23 so as to be configured as an apparatus for simultaneously dissolving and processing a plurality of injection needles 2. 3) It is also possible to arrange the injection needle grip 20, the movable electrode 30, the electrode holder 32, etc. by changing their postures by 45 degrees or 90 degrees, and in that case, the metal pieces after melting can be directly collected in the collection box. Can be configured.
