[Detailed description of the device]

[0001]

[Industrial field of application] The present invention relates to a used needle that is most suitable for a person with diabetes mainly suffering from cataract etc. to melt and process the injection needle used for injecting the therapeutic drug solution at home. The present invention relates to a processing device.

[0002]

2. Description of the Related Art Conventionally, as a processing device for a used injection needle, for example, JP-A-60-5155 and JP-A-60-
Those described in Japanese Patent No. 40060 and Japanese Patent Application Laid-Open No. 1-181866 are known.

[0003]

[Problems to be Solved by the Invention] By the way, all of the conventional devices are used in medical institutions such as hospitals, and people with diabetes who have cataracts may find that
It was completely unsuitable as a device for the person himself to melt-process the injection needle used for the treatment.

That is, it is difficult for a visually handicapped person to insert an injection needle into a narrower insertion opening than above and to make contact with a pair of electrodes. Was requested to be provided with a device that can be used for.

The present invention has been made to respond to such a request, and the purpose thereof is that a person with diabetes who has had a cataract or the like uses the injection needle used for the home treatment himself. It is an object of the present invention to provide a used injection needle processing device that is most suitable for melt processing.

[0006]

To this end, according to the present invention, a pair of electrodes are arranged in a cross shape in the housing corresponding to the injection needle insertion opening of the housing, and the electrodes are connected to the injection needle insertion opening from above. A used injection needle that is inserted into contact with the pair of electrodes is melted by a short-circuit current between the electrodes, in a used injection needle processing device, the upper surface of the housing and the injection needle insertion port An injection needle insertion guide member having a substantially L-shaped cross-section for being inserted from above so as to be in contact with the pair of electrodes via an insertion opening was provided at the starting end portion so as to be removable. It is characterized by the configuration.

[0007]

1 is a perspective view of an example of a processing apparatus according to the present invention, in which a housing 1 is a ceiling wall 2, left and right side walls 3, 4 and a front surface. It has a substantially U-shaped cross section having a wall 5 and a back wall 6, has a base plate 7 on its bottom surface, and is divided into two chambers inside, and a waste storage box 8 can be freely taken in and out of one chamber. The transformer 9 and the power cord 10 with a plug are provided in the other room, and the ceiling lamp 2 is provided with a pilot lamp 11, a switch 12 and the like.

An injection needle insertion port 13 is provided in the central vertical direction of the ceiling wall 2, and an injection needle withdrawal guide member, a blind member, etc. are provided in the insertion port 13 to melt the injection needle. Sparks generated during processing are blinded, and the molten injection needle is detached from the injection cylinder and dropped and stored in the waste storage box 8.

On the upper surface of the ceiling wall 2 at the starting end portion of the injection needle insertion port 13, an insertion guide member 15 for the injection needle 14 is erected so as to be removable. To explain further, the guide member 15 is preferably made of a light metal material such as aluminum and has a pair of guide wall portions 16 having an appropriate width and height.
A guide wall portion 1 having a substantially L-shaped cross-section with 16
The lower ends of 6 and 16 are bent outward at a substantially right angle to form mounting plate parts 17 and 17, and the top surface of the ceiling wall 2 is attached to the lower surfaces of the mounting plate parts 17 and 17 with double-sided adhesive tapes 18 and 18 bonded. It is installed as a detachable stand. The guide member 15 enables a person with diabetes who has become visually impaired to easily insert the used injection needle 14 used for the treatment into the thin insertion port 13 and guides the injection needle 14. If the injection needle 14 is inserted right below in contact with the corner portions 19 of the wall portions 16 and 16, the electrodes will be surely contacted with the electrodes described later through the insertion port 13 and melted. Guide wall portion 1 of the guide member 15
The reason why 6 and 16 have a substantially L-shaped cross section and are removable is that the thickness of the syringe barrel 20 can be accommodated by changing the standing position.

On the lower surface of the ceiling wall 2 and immediately below the insertion port 13, there are provided a pair of electrode plates 21 and 22 on which the injection needle 14 inserted through the insertion port 13 abuts and one guide electrode plate 23. They are arranged in a cross shape and separated from each other.
The pair of electrode plates 21 and 22 are formed of a good conductive material, and the upper surface of the tip end portion of the electrode plates 21 and 22 is preferably a carbon electrode 2 having a special composition excellent in wear resistance and non-adhesiveness.
4, 25 are fixed, and a metal guide electrode 26 is fixed on the upper surface of the tip of the guide electrode plate 23. The electrode plate 21 is screwed to and attached to insulators 28 and 29 that are vertically attached to the mounting plate 27, and the electrode plate 22 together with the guide electrode plate 23 are insulators 30 and 3 that are vertically provided to the attachment plate 27.
The electrode plates 21 and 2 are attached by screwing to the electrode plates 1 and 32.
The end of 2 is in electrical contact with electrode plate contact terminals 35, 36 mounted below the ceiling wall 2 via mounting plates 33, 34.

In the above construction, in order to carry out the melting process of the used injection needle, the pair of guide wall portions 1 in the guide member 15 is provided with the injection cylinder 20 with the used injection needle 14 still attached.
When the needle 14 is applied directly to the electrodes 6 and 16 and lowered directly along the guide walls 16 and 16, the tip of the injection needle 14 is brought into contact with the electrode 25 through the insertion port 13 and the upper portion thereof is brought into contact with the electrode 24. Circuit is formed, a large amount of short-circuit current flows instantaneously, the injection needle 14 melts, and is dropped and stored in the waste storage box 8. If the vertical position of the guide member 15 is changed depending on the thickness of the injection cylinder 20, the same apparatus can be used for melting regardless of the thickness.

[0012]

According to the present invention, however, the injection cylinder 20 with the used injection needle 14 still attached is guided by the pair of guide wall portions 16 and 16 of the guide member 15 and lowered as it is. Since the used injection needle 14 is surely inserted into the thin insertion port 13 and is melted by contacting the electrodes 25 and 24, a diabetic person who is visually impaired due to cataract or the like. When the injection needle used in the home treatment is melted by the person himself, this can be easily and safely performed, and the standing position of the guide member 15 can be adjusted in accordance with the thickness of the injection cylinder 20. If changed, it is possible to easily insert and melt-process the injection needle of any large or small injection cylinder.
