An embodiment of an injection needle dissolution treatment apparatus according to the present invention will be described with reference to the drawings.
As shown in FIGS. 1 to 3, the injection needle dissolution treatment apparatus 1 is an apparatus for dissolving a used injection needle used in a hospital or the like after use, and has a rectangular parallelepiped case 10 and an upper end inside the case 10. It comprises a fixed injection needle holding means 20, an electrode device 30 attached to the bottom plate of the injection needle holding means 20, a dust box 12 provided under the electrode device 30, a current supply means 13, and the like. Reference numeral 17 in the figure is a code.
Next, this configuration will be described in detail.

As shown in FIG. 3, the injection needle holding means 20 is provided with an elevating plate 22 for holding an injection needle holder 51 of an injection needle 52 at the upper end of a cylindrical container 21. The elevating plate 22 moves up and down in the container 21 while holding a holder 51. A holder fixing hole 23 is provided in the center, and an insertion hole 25 for an injection needle 52 is formed in the center of the bottom plate 24. Become.
A coil spring 29 is provided on the inner wall surface of the container 21 between the elevating plate 22 and the bottom plate 24 to constantly urge the elevating plate 22 upward.

As shown in FIGS. 4 and 5, the electrode device 30 fixes a support 26 to the back surface of the bottom plate 24 of the container 21, and a first shaft 31 and a second shaft 34 are parallel to the bottom plate on the support 26. The first electrode roller 32 and the second electrode roller 35 are configured on the surfaces of the first shaft 31 and the second shaft 34, respectively.
The first electrode roller 32 is disposed at a position where the lower end of the injection needle 52 whose surface passes through the insertion hole 25 and descends is in contact with the first electrode roller 32, and the second electrode roller 35 is located below the side of the first electrode roller 32. It has a fixed interval and is arranged at a position where the lower end of the injection needle 52 contacts.
The first electrode roller 32 has a smaller diameter than the second electrode roller 35, and both are made of carbon.

A first gear 33 is attached to the tip of the first electrode roller 32, a second gear 36 is attached to the tip of the second electrode roller 35, and the first gear 33 and the second gear 36 are engaged with each other. The gear 36 is provided with a reverse rotation prevention means 37. The first gear 33 has a larger diameter than the second gear 36.
The gear ratio (diameter ratio) of the first gear 33 is the same as that of the second gear 36 or is linked to the second gear 36 if the first gear 33 is larger in diameter than the second gear 36. Since the rotation of the second electrode roller 35 is the same or faster than the rotation of the first electrode roller 32, the injection needle 52 is smoothly inserted and dissolved, and the injection needle attached to the surface of the electrode roller The remnants fall quickly.

The reverse rotation prevention means 37 is made of a rectangular metal piece whose end is fixed to the arm 27 fixed to the bottom plate 24, and the second gear 36 is forwardly rotated by bringing its tip into contact with the surface of the second gear 36 ( Although not act when the counterclockwise direction) in FIG. 5, than is the tip of the reverse rotation prevention means 37 reverses is prevented Upon the teeth of the second gear 36 when reversed (same clockwise direction) (see FIG. 5 ).

  The dust box 12 accommodates the waste of the injection needle after dissolution, and has a structure with an open upper surface. The dust box 12 is disposed below the electrode device 30 and can be pulled out from the front of the case 10 as shown in FIGS. It is configured.

A current supply means 13 for supplying a dissolution current to the injection needle 52 via the two electrode rollers 32 and 35 is provided at the lower part in the case 10. This current supply means 13 comprises a rectifier, a control means, etc., and its plus terminal is connected to the first electrode roller 32 via a cable (not shown), and its minus terminal is connected to the second electrode roller 35 via a cable (not shown). Has been.
In the figure, reference numeral 19 is a main switch, 11A is a power lamp, 11B is an end lamp, and 14 is a limit switch.

Next, the operation of the injection needle dissolution treatment apparatus 1 will be described.
As shown in FIG. 3, when the main switch 19 is turned on, the power lamp 11A is turned on. Thereafter, as shown in FIG. 6, the holder 51 of the used injection needle 52 is inserted into the holder fixing hole 23 of the elevating plate 22 and fixed.
At this time, the holder 51 is sandwiched and held in the holder fixing hole 23, and the tip of the injection needle 52 is inserted into the insertion hole 25.

  Next, when the user depresses the syringe 50, the lift plate 22 descends against the elastic force of the coil spring 29 as shown in FIG. 7, and the tip of the injection needle 52 is the first electrode of the electrode device 30. Contact with the roller 32 (FIG. 9A).

When the syringe 50 is further pushed down, the injection needle 52 descends while maintaining contact with the first electrode roller 32 and contacts the second electrode roller 35 (FIG. 9B). By this contact, the second electrode roller 35 is short-circuited by the injection needle 52, and the injection needle 52 dissolves in about 1 second.
At this time, dissolution of the injection needle 52 proceeds from the lower end, and dissolution of the injection needle 52 proceeds until the elevating plate 22 stops (FIG. 9C). The melted metal pieces fall into the dust box 12.

When the elevating plate 22 is lowered to the lowermost end, the limit switch 14 is turned on, the supply of current is stopped, and the end lamp 11B is lit.
Thereafter, the syringe 50 is lifted and pulled out together with the lifting of the lift plate 22, the injection needle 52 is removed and discarded, and the main switch 11A is turned off.

At this time, the injection needle 52 is sterilized and cannot be reused, and its tip is not sharp and has a round shape, which is safe.
Thereafter, the dust box 12 may be pulled out to discard the waste. The dust box 12 slightly protrudes from the surface of the case 10, and when the protruding portion is pushed in, the dust box 12 jumps out of the case 10 to turn off the limit switch 12a for the dust box and automatically turn on the power. This is a mechanism that can be cut off, and is safe because the injection needle 52 is not dissolved when the dust box 12 is taken out.

As described above, in the present embodiment, the used injection needle 52 is inserted into the fixing hole 23 of the holder of the elevating plate 22 and the used injection needle 52 is simply and reliably dissolved by simply pressing the syringe 50 down. It is safe to remove the needle 52 from the syringe 50.
Therefore, it is possible to reliably prevent accidents such as accidentally sticking a used injection needle 52 into a hand or a finger. In addition, since the length of the injection needle 52 is about 1/5, the amount of waste can be reduced, leading to improvement of environmental problems.

Further, since the gear reverse rotation prevention mechanism 37 is attached to the second gear 36 of the second electrode roller 35, the dissolution residue of the injection needle remaining on the electrode roller is reversed when the injection needle is pulled out. This prevents accidents such as clogging between the electrodes and locking of the electrode roller, resulting in poor melting operation or blown fuse. The gear reverse rotation prevention mechanism 37 can be attached to the first gear 33 of the first electrode roller 32.

Since a thermal protector (not shown) is added to the coil in the transformer of the current supply means for supplying the electrode needle 30 with the dissolution current of the injection needle, an overcurrent prevention mechanism is provided. Accidents can be prevented.

Further, since the syringe 50 is stably held by the elevating plate 22 and descends and melting is performed at the lower position, even when a spark is generated when the injection needle 52 is melted, this spark is not visible or the spark is not in the holder. There is no risk of damaging the user by leaking from the fixing hole 23.
In addition, it has the effects of reducing the loss of working hours due to accidents, improving the quality of medical services, and improving social responsibility of medical institutions.
