〔産業上の利用分野〕
本発明は、医療分野において使用される注射針の廃棄を
行うための処理装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a processing device for disposing of injection needles used in the medical field.
近年、防疫の必要性から、また魚沸消毒を行う手間を省
く意味から使い捨ての注射針が広く使用されている。し
かし、かかる使い捨ての注射針はそのまま廃棄処分する
と、例えばこれを注射器本体から取外すときやゴミ袋の

搬の際などに手指等を突き刺す等の傷害が発生し、その
結果、エイズウィルス、ウィルス性肝炎その他の病原菌
に感染するという不慮の重大事故が発生する。In recent years, disposable syringe needles have been widely used due to the need for epidemic prevention and to save the trouble of sterilizing by boiling. However, if such disposable syringe needles are disposed of as they are, for example, when they are removed from the syringe body, or when they are placed in a garbage bag, the bag may break and the tip protrudes, resulting in injury to hands, etc., when transporting the needle. Injuries such as punctures occur, resulting in unexpected serious accidents such as infection with the AIDS virus, viral hepatitis, and other pathogens.
このような危険を未然に防ぐため、特開昭６０−５１５
５号公報では、互いに離間した一対の電極間に針を架橋
させて接触させ、この針を焼損させる針処理装置が示さ
れている。In order to prevent such dangers from occurring,
No. 5 discloses a needle treatment device in which a needle is bridged between a pair of electrodes separated from each other and brought into contact with each other, and the needle is burnt out.
しかし、前記特開昭６０−５１５５号公報のものでは、
焼損のためにスパーク（火花）かはなばなしく発生し、
これが看護婦を初めとする婦女子に対し恐怖感を与える
。However, in the above-mentioned Japanese Patent Application Laid-Open No. 60-5155,
Due to burnout, sparks are generated rapidly,
This creates a sense of fear for nurses and other women.
この火花を外部から見えなくするように目隠しをするこ
ともなされるが、スリット等からもれることは防止でき
ず、また焼損の際の衝撃音などは消すことができない。Blindfolds are sometimes used to prevent the sparks from being seen from the outside, but this does not prevent the sparks from leaking through the slits or the like, and it also cannot eliminate the impact noise caused by the burnout.
さらに、目隠しをすることは針の処理状態が外部から確
認できないことになり、不安感を増す。Furthermore, wearing a blindfold means that the state of needle processing cannot be checked from the outside, which increases the sense of anxiety.
本発明の目的は前記従来例の不都合を解消し、火花を発

に破損させることができる注射針の処理装置を提供する
ことにある。SUMMARY OF THE INVENTION An object of the present invention is to eliminate the disadvantages of the prior art and to provide an injection needle processing device that can mechanically completely break needles without generating sparks and while sterilizing the needles.
本発明は前記目的を達成するため、ハウジングの針挿入
口の内側に、挿入した針に離間して接触する一対の電極

合せによる針カッターとを設け、かつ前記電極に電極間
の針をその太さに応じて高温に発熱するだけの給電手段
を接続したことを要旨とするものである。In order to achieve the above object, the present invention includes a pair of electrodes that contact the inserted needle at a distance inside the needle insertion opening of the housing, and a needle cutter that is located between the electrodes and is a combination of a fixed cutter and a movable cutter. The main feature is that a power supply means is connected to the electrodes to generate heat to a high temperature according to the thickness of the needle between the electrodes.
本発明によれば、ハウジングの針挿入口に注射器につい

。According to the present invention, when the needle attached to the syringe is inserted into the needle insertion port of the housing, the needle is connected between the separated electrodes, for example, at the tip and halfway, and between the electrodes, the needle is A voltage is applied by the current flowing in response, and the needle heats up to a high temperature, sterilizing the inside of the needle and reducing its hardness.
同時に針カッターの可動カッターが電極間を動き、赤熱
して柔らかくなった針の途中を切断し、この切り口は尖
りのない押潰されたものとなる。At the same time, the movable cutter of the needle cutter moves between the electrodes and cuts the middle of the red-hot and soft needle, leaving the cut end flat and crushed.
このような針の処理状態は火花等を発生させないので、
ハウジングの窓から容易に確認できる。This type of needle treatment does not generate sparks, so
Easily visible through the housing window.

As shown in FIG. 4, the movable electrode 101a is assembled so that the individually formed needle insertion holes 12 overlap, and the movable electrode 101a is slid by a movable source such as a motor to the fixed electrode 100a. On the other hand, since the overlapping position of the needle insertion hole 12 is narrow, it also serves as a chuck mechanism for fixing the needle 13.

狭まることにより針１３をチャックする。When the needle 13 is inserted, the needle thickness sensor 9 detects the thickness and outputs it to the control device 20. In response to this output, the movable electrode 101a slides according to the output of the control device 20, and the fixed electrode 100a The needle 13 is chucked by narrowing the insertion hole 120 overlapping with the needle 13.

細い場合は小さく、太い場合は大きい。On the other hand, the electrode 10b is pushed backward by the tip of the needle 13 against the spring 14, so that the movable element 15 moves to the operating element 16.
Press aG to turn on the microswitch 16, and as a result, a voltage is applied to the electrodes 10a, 10b. This voltage amount is determined by the current adjustment circuit 25 based on the output of the control device 20 based on the output of the needle 13 thickness sensor 9, and is small when the needle 13 is thin, and large when the needle 13 is thick.
針１３はステンレスで形成さ、かつその断面積はきわめ
て微小であるため、電気抵抗は非常に大きい。従って、
電極１０ａが接する針１３の途中と電極１０ｂが接する
針１３の先端間は電極１０ａ、 １０ｂに印加される電
圧が比較的低電圧であっても容易に発熱現象が起こる。Since the needle 13 is made of stainless steel and has an extremely small cross-sectional area, its electrical resistance is extremely large. Therefore,
Heat generation easily occurs between the middle of the needle 13 where the electrode 10a contacts and the tip of the needle 13 where the electrode 10b contacts, even if the voltage applied to the electrodes 10a and 10b is relatively low.
ただし、この発熱は針１３を赤熱させるにとどまり、ス
パークを生じて焼損させることのないように前記電圧は
設定される。However, this heat generation only makes the needle 13 red-hot, and the voltage is set so as not to generate sparks and cause burnout.
このような針１３の発熱の結果、針１３はその硬度が低
下し柔らか（なるとともに内部の菌は熱で殺菌される。As a result of the heat generation of the needle 13, the needle 13 becomes less hard and becomes soft (as well as bacteria inside it are sterilized by the heat).
以上のように電極１０ａ、 １０ｂに電圧が印加される
と同時にモーター１７に通電され、カッター１１ｂが回
転し始める。As described above, the voltage is applied to the electrodes 10a and 10b, and at the same time, the motor 17 is energized and the cutter 11b begins to rotate.
回転するカッター１１ｂは、固定カッター１１ａと刃が

３は熱せられて柔らか（なっているのでその輪状の切り
口はつぶれて閉塞されたものとなる。The rotating cutter 11b cuts the red-hot needle 13 with the stationary cutter 11a and the blade where they are lined up, and the needle 1
The cut end of No. 3 falls downward and is stored in the container 6. The cut in this case is perpendicular to the axial direction of the needle 13, and the sharp part such as the tip is not completely cut.
3 is heated and becomes soft, so the ring-shaped cut is crushed and closed.
ところで、前記可動するカッター１１ｂを動かすモータ

が行われ始動するもので、１〜数秒単位で１回転し再度
マイクロスイッチ１８に触れる１回転したところで停止
する。By the way, talking about the movement of the motor 17 that moves the movable cutter 11b, the motor 9-17 is energized and started on the condition that its shaft is in contact with the microswitch 18, and the motor 17 moves in units of 1 to several seconds. It rotates once and stops when it touches the micro switch 18 again.
また、電極１０ｂによりマイクロスイッチ１６が入ると

処理装置３の作業終了として消灯する。Also, when the microswitch 16 is turned on by the electrode 10b, one of the indicator lamps 24 lights up and these electrodes 10b turn on.
A, 10b and the cuffer 11 notify that the needle processing device 3 has started to operate, but the indicator lamp 24 indicates that the needle processing device 3 has completed its work when the motor 16 rotates once and the microsinch 18 enters. Lights out.
なお、先に述べたように針１３の先端が切落とされると
、電極１０ｂはバネ１４の力でもとにもどり、マイクロ
スイッチ１６はＯＦＦとなる。Note that, as described above, when the tip of the needle 13 is cut off, the electrode 10b returns to its original state by the force of the spring 14, and the microswitch 16 is turned off.
このようにして針１３は切断処理されるが、針１３自体

作を繰り返して、２度以上に分けて処理することも可能
である。The needle 13 is cut in this way, but depending on the length of the needle 13 itself, it is also possible to push the needle 13 deeper after cutting and repeat the same operation to cut the needle in two or more times.
そして、以上の処理作業は窓２２を介してハウジング１
の外部から監視できる。The above processing work is carried out through the window 22 in the housing 1.
can be monitored from outside.

のとなる。(Effects of the Invention) As described above, the injection needle processing device of the present invention performs processing by applying voltage to generate heat in the needle while cutting it with a cutter, and does not cause sparks or bad odors, as in the case of burnout. Sterilization can be achieved by heat generation without causing any nuisance, and the needle becomes soft due to heat generation, making it possible to cut the needle reliably and easily.

ある。Moreover, since no sparks are generated, the processing work can be visually observed from the outside, giving a sense of security.
