Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a treatment device for a used injection needle, which is most suitable for a person with diabetes mainly suffering from cataract or the like to melt and process the injection needle used for injecting the therapeutic drug solution at home at home. .

[0002]

[Prior art]

 Conventionally, as a treatment device for a used injection needle, those described in, for example, JP-A-60-5155, JP-A-60-40060, and JP-A-1-181866 are known.

[0003]

[Problems to be solved by the device]

 By the way, all of the conventional devices are used in medical institutions such as hospitals, because a person with diabetes who suffers from cataracts melts the injection needle used for the treatment at home. It was completely unsuitable as a device.

That is, it is difficult for a visually handicapped person to insert an injection needle into a narrower insertion opening than above and to contact a pair of electrodes, and this point has been improved. There has been a demand for provision of an easily usable device.

The present invention has been made in response to such a request. The purpose of the present invention is that a person with diabetes who has had a cataract or the like should use the injection needle he used for his home treatment. It is to provide a treatment device for a used injection needle, which is most suitable for melt processing by itself.

[0006]

[Means for solving problems]

 For this purpose, the present invention has a structure in which a pair of electrodes are arranged in a cross shape in the housing corresponding to the injection needle insertion opening of the housing and inserted into the injection needle insertion opening from above to contact the pair of electrodes. The used needle is melted by a short circuit current between both electrodes.In the used needle processing device, the needle is placed above the housing and at the beginning of the needle insertion port, the needle is placed above. The injection needle insertion guide member having a substantially L-shaped cross section for being inserted so as to come into contact with the pair of electrodes via the insertion port is detachably provided upright. .

【Example】

 An embodiment will be described with reference to the drawings and its operation. FIG. 1 is a perspective view showing an example of a processing apparatus according to the present invention. A housing 1 includes a ceiling wall 2, left and right side walls 3, 4, a front wall 5 and It has a substantially U-shaped cross section with a back wall 6, and has a base plate 7 on its bottom surface, and the inside is divided into two rooms, and a waste storage box 8 can be inserted and taken out in one room as a self-insertion. The other room is provided with a transformer 9, a power supply cord 10 with a plug, and the like, and the ceiling wall 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 longitudinal direction of the ceiling wall 2, and an injection needle withdrawal guide member, a blind member, etc. are provided at 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 substantially L-shaped cross section having a pair of guide wall portions 16 and 16 having an appropriate width and height. The lower ends of the guide wall portions 16 and 16 are bent outward at a substantially right angle to form mounting plate portions 17 and 17, and a ceiling is provided on the lower surfaces of the mounting plate portions 17 and 17 with double-sided adhesive tapes 18 and 18 bonded. It is installed on the wall 2 so as to be removable. This guide member 15 enables a person with diabetes who is 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 the corners 19 of the wall portions 16 and 16 in that state, they will surely come into contact with the electrode described later through the insertion port 13 and be melted. The guide walls 16 and 16 of the guide member 15 have a substantially L-shaped cross section and are detachable so that the thickness of the syringe barrel 20 can be accommodated by changing the standing position. Is.

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 with which the injection needle 14 inserted through the insertion port 13 contacts 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 a carbon electrode 24 having a special composition, which is preferably excellent in abrasion resistance and non-adhesiveness, is preferably formed on the upper surface of the tip of the electrode plates 21 and 22. , 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 and attached to insulators 28 and 29 which are vertically attached to the mounting plate 27, and the electrode plate 22 together with the guide electrode plate 23 are insulators 30 and 31, which are vertically attached to the mounting plate 27. The electrode plates 21 and 22 are attached by screwing to 32, and the ends of the electrode plates 21 and 22 are in electrical contact with the electrode plate contact terminals 35 and 36 that are mounted below the ceiling wall 2 via the mounting plates 33 and 34. .

In the above configuration, in order to perform the melting treatment of the used injection needle, the injection cylinder 20 with the used injection needle 14 still attached is applied to the pair of guide wall portions 16 and 16 of the guide member 15. If the needle 14 is lowered right below the guide walls 16 and 16 as it is, the tip of the injection needle 14 is brought into contact with the electrode 25 through the insertion port 13 and the upper part thereof is brought into contact with the electrode 24 to form a circuit. Then, 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. By changing the standing position of the guide member 15 depending on the size of the injection cylinder 20, the same apparatus can be used for the melting process regardless of the size.

[0012]

[Effect of device]

 Thus, according to the present invention, the syringe barrel 20 with the used syringe needle 14 still attached is guided by the pair of guide wall portions 16 and 16 of the guide member 15, and is lowered as it is to dispose the used syringe needle. Since 14 is securely inserted into the thin insertion opening 13 and melted by contacting the electrodes 25 and 24, a diabetic person who is visually impaired due to cataract or the like can be treated at home. In the case where the injection needle used in step 1 is melt processed by the person himself, this can be done easily and safely, and if the standing position of the guide member 15 is changed according to the thickness of the injection cylinder 20. It can be easily inserted and melt processed regardless of the size or size of the injection needle.
