[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for sterilizing used medical injection needles and disposing of them.

[0002]

2. Description of the Related Art An apparatus of this type is conventionally known, for example, from Japanese Patent Application Laid-Open No. HEI 1-107768. It comprises a crucible, an induction wire loop wound around the crucible, an AC voltage applying device, and a tray for the melt in the crucible, and discards used medical injection needles. It is configured to be.

[0003]

[Problems to be solved by the invention]
Because of the structure in which the injection needle is dissolved in the crucible, a large amount of odorous gas is generated upon dissolution. In addition, since it is configured to be cooled after being cooled in a tray and disposed of, it cannot be easily and promptly disposed of in a treatment room such as a hospital. The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a device capable of minimizing the generation of odorous gas as much as possible and easily and quickly disposing of the device in a treatment room such as a hospital. Make it an issue.

[0004]

Means for Solving the Problems The present invention is configured as follows to solve the above problems, for example, as shown in FIGS. That is, the case body 1 and the case body 1
At least a pair of carbon electrodes 3 projecting from the upper surface of
A voltage application circuit 10 that is housed in the case body 1 and applies a required voltage to the carbon electrode 3; and an injection needle collection box that is housed detachably from the case body 1 and located below the carbon electrode 3. 5, wherein the used medical injection needle 7 is cross-linked between the pair of carbon electrodes 3 and sterilized by red heat. is there.

[0005]

In the present invention, a used medical injection needle 7 is bridged between a pair of carbon electrodes 3 protruding from the upper surface of the case body 1 and sterilized by red heat. The injection needle 7 thus sterilized is collected in the injection needle collection box 5 case located below the carbon electrode 3. In other words, in the present invention, since only the injection needle having a small heat capacity is red-heated and sterilized, only the injection needle is dissolved in a crucible,
Almost no odorous gas is generated, and the used medical injection needle can be easily and promptly disposed of in a treatment room such as a hospital.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in more detail with reference to the drawings. FIG. 1 is a schematic view of a medical injection needle disposal apparatus according to an embodiment of the present invention, and FIG. 2 is a perspective view showing an appearance of the apparatus.

This waste treatment apparatus is housed in the case body 1, two pairs of carbon electrodes 3 projecting from a long hole 2 formed in the upper surface of the case body 1, and the case body 1.
A voltage application circuit 10 for applying a required voltage to each of the two pairs of carbon electrodes 3; a drawer-type injection needle collection box which is detachably housed in the case body 1 and located below the carbon electrodes 3; 5 is provided.

[0008] One of the two pairs of carbon electrodes 3, 3 is used for sterilizing the dental needle 7a removed from the syringe 6, and the opposing needle contact surface is substantially formed. It is formed in a V shape. The other carbon electrodes 3b, 3b are for a general injection needle which is sterilized while the injection needle 7b is attached to the syringe 6, and both of them are used to connect the used medical injection needle 7a or 7b to a pair of carbon electrodes. The needle is red-heated by Joule heat and sterilized, and is configured to be properly used according to the shape of the injection needle as described above. Incidentally, in the present embodiment, graphite is used as the material of the carbon electrode 3. This is to ensure strength and durability. In addition,
Reference numerals 4a and 4b in FIG.
This is a protective cover for protecting a.3b.

The voltage application circuit 10 includes a 100 volt AC power outlet 11, a transformer 18, a power switch 12 interposed therebetween, and the like, and applies a required voltage to the carbon electrode 3. It is configured. Incidentally, in the present embodiment, a low voltage of about 5 volts is applied to the carbon electrode 3, and the configuration is such that safety is ensured even when the carbon electrode 3 is touched by human hands. In FIG. 1, reference numeral 13 denotes a circuit breaker, 14 denotes an overcurrent alarm lamp, 15 denotes a pull-out alarm lamp of the draw-out type needle collection box 5, 16 denotes a switch that operates in conjunction with the pull-out operation of the needle collection box 5, 17 is a power indicator lamp.

The operation of the apparatus of this embodiment will be described below. First, when the power switch 12 is turned on, the power indicator lamp 17 is turned on, and a low voltage is applied to the secondary side of the transformer 18. When the used injection needles 7a and 7b are brought into contact with the carbon electrode 3 as shown in FIG. 1, the injection needle itself becomes red-hot due to Joule heat and becomes brittle debris. Since the injection needle has a small heat capacity and is quickly cooled, it is dropped from the gap between the carbon electrodes 3a and 3a or 3b and 3b and collected in the injection needle collection box 5. When the injection needles have accumulated to some extent, the collection box 5 can be pulled out with the handle 5a and discarded as general waste.

It should be noted that the present invention is not limited to the above-described embodiment, and it can be said that the present invention can be carried out by appropriately changing the form of the case, the injection needle collection box, the carbon electrode and the like and the number of carbon electrodes. No need.

[0012]

[Effects of the Invention] The present invention is configured as described above, and only the syringe needle having a small heat capacity is red-heated and sterilized. Therefore, as compared with the case where the injection needle is dissolved in the crucible, almost no odorous gas is generated. In addition, the medical injection needle used in a treatment room such as a hospital can be easily and promptly disposed of.
