Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for sterilizing and disposing of used medical needles.

[0002]

[Prior Art]

 As this type of device, a device disclosed in, for example, Japanese Patent Application Laid-Open No. 1-107768 has been conventionally known. It is equipped with a crucible, a melting induction coil wound around the crucible, an AC voltage application device, and a pan for the melt in the crucible, and discards used medical injection needles. Is configured to process.

[0003]

[Problems to be solved by the device]

 Since the conventional example has a structure in which the injection needle is dissolved in the crucible, a large amount of malodorous gas is generated during the dissolution. In addition, since the structure is such that it is cooled in the saucer and then discarded, it cannot be easily and quickly disposed of in a treatment room such as a hospital. The present invention has been made in consideration of such circumstances, and it is an object of the present invention to provide a device that suppresses the generation of malodorous gas as much as possible and that can be easily and quickly disposed of in a treatment room such as a hospital. This is a technical issue.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention is configured as follows, for example, as shown in FIGS. That is, a case main body 1, at least a pair of carbon electrodes 3 protruding from the upper surface of the case main body 1, a voltage application circuit 10 housed in the case main body 1, and applying a required voltage to the carbon electrode 3. , Which is detachably accommodated in the case body 1 and comprises an injection needle recovery box 5 located below the carbon electrode 3, and a used medical injection needle 7 is provided between the pair of carbon electrodes 3. This is a device for disposing of a medical injection needle, characterized in that it is configured so as to be bridged in between and sterilized by red heat.

[0005]

[Work]

 In the present invention, a used medical injection needle 7 is bridged between a pair of carbon electrodes 3 projecting from the upper surface of the case body 1 for red heat sterilization. The injection needle 7 thus sterilized is collected in the case 5 of the injection needle collection box located below the carbon electrode 3. In other words, in the present invention, since only the injection needle with a small heat capacity is red-heated and sterilized, there is almost no foul-smelling gas compared to the one that dissolves in a crucible, and it is used in a treatment room such as a hospital. The medical injection needle can be disposed of easily and quickly.

【Example】

 Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings. FIG. 1 is a schematic view of a medical needle disposal device according to an embodiment of the present invention, and FIG. 2 is a perspective view showing the appearance of the device.

This disposal device is housed in the case main body 1, two pairs of carbon electrodes 3 and 3 protruding from a long hole 2 formed in the upper surface of the case main body 1, and housed in the case main body 1. A voltage application circuit 10 for applying a required voltage to each of the two pairs of carbon electrodes 3, and a retractable needle collection needle that is detachably housed in the case body 1 and is located below the carbon electrode 3. And a box 5.

One of the two pairs of carbon electrodes 3 and 3 is used to sterilize the dental injection needle 7a removed from the syringe 6, and one of the carbon electrodes 3a and 3a has an opposite needle contact surface. It is formed in a substantially V shape. The other carbon electrode 3b, 3b is for a general injection needle that is sterilized while the injection needle 7b is attached to the syringe 6, and both of them are used as a pair of used medical injection needle 7a or 7b. The needle itself is red-heated by Joule heat to sterilize it by bridging between carbon electrodes, and is configured to be used properly according to the form of the injection needle as described above. By the way, in the present embodiment, graphite is used as the material of the carbon electrode 3. This is to secure strength and durability. Reference numerals 4a and 4b in FIG. 2 are protective covers for protecting the brittle carbon electrodes 3a and 3b, respectively.

The voltage application circuit 10 is composed of a 100-volt AC power supply outlet 11, a transformer 18, and a power supply switch 12 and the like interposed therebetween, and applies a required voltage to the carbon electrode 3. It is configured. By the way, in this embodiment, a low voltage of about 5 bolts is applied to the carbon electrode 3, and the carbon electrode 3 is configured to ensure safety even if it is touched by a person. In FIG. 1, reference numeral 13 is a circuit breaker, 14 is an overcurrent warning lamp, 15 is a pull-out warning lamp of the pull-out type needle collection box 5, and 16 is a switch interlocking with the pull-out operation of the needle collection box 5. Reference numeral 17 is a power source display 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 a brittle debris. Since this injection needle has a small heat capacity and is cooled down in a short time, it is dropped as it is from the gap between the carbon electrodes 3a, 3a or 3b, 3b and collected in the injection needle collection box 5. When the injection needles have accumulated to a certain extent, the recovery box 5 can be pulled out by holding the handle 5a and discarded as general waste.

It should be noted that the present invention is not limited to the above-described embodiment, but it is also possible to make various changes in the form of the case, the injection needle collection box, the carbon electrode, etc. and the number of carbon electrodes. Does not need

[0012]

[Effect of the device]

 Since the present invention is configured as described above and only sterilizes by heating only the injection needle having a small heat capacity by red heat, it produces almost no foul-smelling gas as compared with the one that dissolves in a crucible, and it can be used for treatment in hospitals and the like. It is possible to easily and quickly dispose of used medical needles indoors.
