Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a used syringe processing apparatus and method for safely and efficiently disposing of used syringes in medical facilities such as hospitals.

[0002]

2. Description of the Related Art Conventionally, used syringes are handled as waste as they are.

[0003]

However, when it is treated as waste, the injection needle is likely to damage the skin due to its sharp tip, and there is a social problem that the wound may be infected with pathogenic bacteria. Has become. Therefore, although the used syringe is incinerated together with other dust and the like, a similar risk remains in the process of handling until collection and incineration. Further, when the metal material of the injection needle and the synthetic resin material of the injection cylinder are incinerated in one piece, there remains a problem of recycling waste resources.

[0004]

The present invention is intended to solve the above problems, and the following features are added to the structure of the solving means. (1) Insert the syringe by tilting it forward (lowering it forward)
Facilitates ejection of molten needle. (2) A syringe guide is provided at the insertion port to facilitate gripping of the grip type. (3) A pair of grip type grips the base flange of the syringe. (4) The moving electrode is moved up and down in conjunction with the upper grip type. (5) The injection needle is electrically heated between the butting electrode and the moving electrode. (6) Remove the syringe barrel to separate it from the needle treatment. (7) The upper grip mold surface is formed in a large rounded shape to prevent adhesion. (8) The molten injection needle is discharged into a storage box for disposal. (9) The process of the injection needle is automatically completed in one cycle from the contact with the butting electrode. From the above, the means for solving the above-mentioned problems are configured as follows. (1) A syringe guide portion of an insertion port that guides an inserted used syringe by tilting it forward, an abutting electrode installed so as to be movable back and forth along the center line of the syringe guide, and a fixed lower grip. A pair of grip types that move up and down the upper grip type relative to the mold to grip or open the base flange of the injection needle of the insertion syringe, and a moving electrode that moves up and down in conjunction with the upper grip type and contacts the base of the injection needle. And a current-carrying circuit between the electrodes for heating and melting the tip of the injection needle, and an injection needle housing box for receiving the molten injection needle discharged by opening the upper grip type. When it detects contact with the contact electrode, it lowers and contacts the moving electrode that interlocks with the downward closing of the upper grip type, heats the tip of the injection needle electrically, and raises the moving electrode that interlocks with rising and opening of the upper grip type. Spent syringe processing device characterized by until removal is configured as to operate sequentially a cycle. (2) Use a pair of grip types that grip or open the base flange of the injection needle with respect to the inserted used syringe, and energize between the electrodes that are in contact with the tip of the injection needle and near the base of the injection needle. While the tip was being heated and melted, the syringe barrel was withdrawn and discarded, and the remaining molten syringe needle was discharged into the storage box by the grip-type opening and disposed of. A method for treating a used syringe characterized by a separation treatment. When the tip of the injection beam is melted by applying electricity between the electrodes, the syringe barrel is pulled out and disposed of.The melted needle is opened by a grip type and discharged into the storage box. A method for treating a used syringe, which is characterized by a separation treatment that causes it to be disposed of. (3) The lower grip mold surface is adapted to the base flange of the injection needle, while the upper grip mold surface is formed in a large radius shape to prevent adhesion to the upper mold at the time of discharge (1) The processing device for the used syringe according to the item.

[0005]

According to the above-mentioned solution means, since the grip type grips the base flange of the injection needle, the syringe barrel can be easily pulled out. The syringe barrel is separated and disposed of.
In addition, the moving electrode interlocks and abuts near the base of the injection needle,
Since electricity is applied between the butting electrode and the abutting electrode, the tip of the injection needle is heated and melted by Joule heat and deformed into a round shape. Also, when the upper grip type is opened, the molten injection needle is easily floated up and ejected by the knockout pin, and on the other hand, the upper grip type surface has a large rounded surface, which prevents the injection needle from sticking to the upper grip type. Further, since the injection needle is tilted forward and inserted, the molten injection needle immediately falls into the storage box below and is disposed of. Further, since these operations are completed in one cycle, the treatment of the injection needle is automatically completed only by inserting the used syringe into the insertion port and pulling out the syringe barrel.
