Description

加熱処理装置及び加熱処理方法Heat treatment apparatus and heat treatment method
　本発明は、熱線性光源の光を照射して加熱処理する加熱処理装置及び加熱処理方法に関する。 The present invention relates to a heat treatment apparatus and a heat treatment method for performing heat treatment by irradiating with light from a heat ray light source.
　使用済みの注射器等の医療廃棄物は、先進国の都市部においては専門の処理業者によって回収され安全に処理される。しかし、交通の便が悪い等の理由から処理業者が頻繁に回収しない場合もあるため、注射器を使用後速やかに無害化することが望ましい。本願の発明者の一人は、注射器を溶融処理して無害化する装置を提案した（例えば、特許文献１）。 医療 Used syringes and other medical waste are collected and handled safely by specialists in urban areas in developed countries. However, since there are cases where the processing company does not collect frequently due to reasons such as poor transportation, it is desirable to make the syringe harmless immediately after use. One of the inventors of the present application has proposed an apparatus for detoxifying a syringe by melting it (for example, Patent Document 1).
　特許文献１に記載の注射器溶融装置は、水平面から傾いた長軸の扁長楕円面の一部となる形状の光反射面を有する光反射部で、楕円の第１焦点に配置した光源の光を反射させ、光透過性を有するカバー部を透過させて、第２焦点に載置した注射器に照射させる装置である。この注射器溶融装置は、注射器を載置部にセットした後、注射器の針先端から針基に向けて第２焦点の位置が変化するように載置部を移動することにより溶融処理することができた。 The syringe melting device described in Patent Document 1 is a light reflecting portion having a light reflecting surface having a shape that is a part of a long and slender elliptical surface inclined from a horizontal plane, and light from a light source disposed at the first focal point of the ellipse. This is a device that reflects the light beam, transmits the light-transmitting cover portion, and irradiates the syringe placed on the second focal point. This syringe melting device can be melted by setting the syringe on the mounting portion and then moving the mounting portion so that the position of the second focal point changes from the needle tip of the syringe toward the needle base. It was.

　特許文献１に係る注射器溶融装置は、載置された注射器の側方に、光源からの光を第２焦点へ向けて反射する反射鏡をさらに具備することにより処理効率を向上させている。しかし、注射器の太さや長さは多様であり、注射器のサイズによっては、反射鏡で反射する光が注射器に照射されないという問題があった。 The syringe melting apparatus according to Patent Document 1 improves processing efficiency by further including a reflecting mirror that reflects light from the light source toward the second focal point on the side of the placed syringe. However, there are various thicknesses and lengths of the syringe, and depending on the size of the syringe, there is a problem that the light reflected by the reflecting mirror is not irradiated on the syringe.
　また、載置部を移動させるため、注射器を強固に固定させる必要があり、多様なサイズの注射器を固定する機構が必要であり、コストを上げる要因となっていた。 In addition, in order to move the mounting portion, it is necessary to firmly fix the syringe, and a mechanism for fixing syringes of various sizes is necessary, which has been a factor in increasing costs.
　本発明は、上記実情に鑑みてなされたものであり、高効率で低コストの加熱処理が可能な加熱処理装置等を提供することを目的とする。 The present invention has been made in view of the above circumstances, and an object thereof is to provide a heat treatment apparatus capable of performing heat treatment with high efficiency and low cost.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the description, an XYZ coordinate system including an X axis, a Y axis, and a Z axis that are orthogonal to each other as appropriate is used.
　本実施形態に係る加熱処理装置１は、扁長楕円体の反射鏡を用いた集光加熱により、加熱対象物を溶融し無害化する装置である。本実施形態では、加熱対象物が注射針及びシリンジからなる注射器３０１である場合について説明する。この加熱処理装置１は可搬性の小型の装置であり、この装置を必要とする場所へ容易に運ぶことができる。以下、加熱処理装置１の構成について、詳述する。 The heat treatment apparatus 1 according to the present embodiment is an apparatus that melts and detoxifies a heating target object by condensing heating using an oblong ellipsoidal reflecting mirror. This embodiment demonstrates the case where the heating target object is the syringe 301 which consists of an injection needle and a syringe. The heat treatment apparatus 1 is a portable small apparatus, and can be easily carried to a place where the apparatus is required. Hereinafter, the configuration of the heat treatment apparatus 1 will be described in detail.
　図１は、加熱処理装置１の内部を示す斜視図である。加熱処理装置１は、内部に各構成を収納した第１筐体１００と、第１筐体１００に組み込まれ、第１筐体１００から分離可能な第２筐体２００を備える。図１に示すようにＸＹ平面が水平面であり、＋Ｚ方向が鉛直上向き方向であるとして説明する。 FIG. 1 is a perspective view showing the inside of the heat treatment apparatus 1. The heat treatment apparatus 1 includes a first housing 100 in which each component is housed, and a second housing 200 that is incorporated in the first housing 100 and is separable from the first housing 100. As shown in FIG. 1, description will be made assuming that the XY plane is a horizontal plane and the + Z direction is a vertically upward direction.
　加熱処理装置１は、下方に熱光線を照射する光ユニット１０１と、光ユニット１０１を吊り下げる吊り下げ部１０２と、光ユニット１０１を水平方向に直線運動させるボールネジ１０３と、光ユニット１０１を冷却する冷却ファン１０４と、第１筐体１００内の空気を排気する排気ファン１０５と、を第１筐体１００内に備える。また、光ユニット１０１の直線運動や、光ユニット１０１への供給電力を制御する制御部１０６を更に、第１筐体１００内に備える。 The heat treatment apparatus 1 cools the optical unit 101 that irradiates heat rays downward, a suspension 102 that suspends the optical unit 101, a ball screw 103 that linearly moves the optical unit 101 in a horizontal direction, and the optical unit 101. A cooling fan 104 and an exhaust fan 105 that exhausts air in the first housing 100 are provided in the first housing 100. In addition, the first housing 100 further includes a control unit 106 that controls linear motion of the optical unit 101 and power supplied to the optical unit 101.
　また、加熱処理装置１は、注射器３０１を支持する支持体２０１と、支持体２０１の向きを固定する磁石２０２と、を第２筐体２００内に備える。第２筐体２００の外壁面には取っ手２０３が備えられており、取っ手２０３を－Ｙ方向に引くことにより、第２筐体２００を第１筐体１００から引き出すことができる。また、支持体２０１には回転レバー２０４が備えられている。回転レバー２０４は第２筐体２００の外壁面に設けた穴を貫通しているため、第２筐体２００の外側から回転レバー２０４を操作することが可能である。 Further, the heat treatment apparatus 1 includes a support body 201 that supports the syringe 301 and a magnet 202 that fixes the orientation of the support body 201 in the second housing 200. A handle 203 is provided on the outer wall surface of the second casing 200, and the second casing 200 can be pulled out from the first casing 100 by pulling the handle 203 in the −Y direction. The support 201 is provided with a rotation lever 204. Since the rotation lever 204 passes through a hole provided in the outer wall surface of the second casing 200, the rotation lever 204 can be operated from the outside of the second casing 200.
　図２は光ユニット１０１と支持体２０１上の注射器３０１との位置関係を示す図であり、注射器３０１の延在方向（Ｙ方向）に垂直な面における断面を注射器３０１の注射針の方向から見た断面図である。 FIG. 2 is a diagram showing the positional relationship between the optical unit 101 and the syringe 301 on the support 201, and a cross section in a plane perpendicular to the extending direction (Y direction) of the syringe 301 is viewed from the direction of the injection needle of the syringe 301. FIG.
　光ユニット１０１は、図２に示すように、長軸１２１を回転軸として楕円を回転させた扁長楕円体の表面の一部となる形状の第１光反射面１１１を内側に形成した光反射部１１３と、扁長楕円体の第１焦点１２２に配置された熱線性光源１１２と、からなる。熱線性光源１１２は、例えばハロゲンランプ、キセノンランプ、メタルハライドランプ等から構成される。 As shown in FIG. 2, the optical unit 101 has a first light reflecting surface 111 having a shape that becomes a part of the surface of an oblong ellipsoid whose ellipse is rotated about the major axis 121 as a rotation axis. Part 113 and the heat-line light source 112 arranged at the first focal point 122 of the oblong ellipsoid. The heat ray light source 112 is composed of, for example, a halogen lamp, a xenon lamp, a metal halide lamp, or the like.
　支持体２０１は、第１光反射面１１１の扁長楕円体の第２焦点１２３に、中心軸が位置するように注射器３０１を支持する複数の支持片２０５と、注射器３０１の中心軸に向かう面に形成した第２光反射面２０６と、を備える。第２光反射面２０６は、Ｙ方向に延在しており、Ｙ方向に垂直な面における断面が半円となっている。 The support 201 has a plurality of support pieces 205 that support the syringe 301 so that the central axis is located at the second focal point 123 of the oblong ellipsoid of the first light reflecting surface 111, and a surface that faces the central axis of the syringe 301. And a second light reflecting surface 206 formed in the above. The second light reflecting surface 206 extends in the Y direction, and the cross section of the surface perpendicular to the Y direction is a semicircle.
　第１光反射面１１１の扁長楕円体の長軸１２１は、鉛直方向（Ｚ方向）に平行である。この構成は、長軸１２１が鉛直方向に対して傾きを有する構成と比較して、光ユニット１０１の移動を繰り返しても、第２焦点１２３と注射器３０１の中心軸がずれる可能性が低いため、長期信頼性を保つことができる。長軸１２１が鉛直方向にあるため、支持体２０１は、熱線性光源１１２の鉛直下方に、第２光反射面２０６が上方を向くように位置する。 The long axis 121 of the oblong ellipsoid of the first light reflecting surface 111 is parallel to the vertical direction (Z direction). Compared with the configuration in which the long axis 121 is inclined with respect to the vertical direction, this configuration is less likely to cause the center axis of the second focal point 123 and the syringe 301 to shift even if the movement of the optical unit 101 is repeated. Long-term reliability can be maintained. Since the long axis 121 is in the vertical direction, the support 201 is positioned vertically below the heat ray light source 112 so that the second light reflecting surface 206 faces upward.
　光反射部１１３は耐熱性の高い任意の材料で形成され、例えば、真鍮等の金属、ガラス、フッ素樹脂などの樹脂材料により形成される。支持体２０１も同様に、耐熱性の高い任意の材料で形成されるが、少なくとも両側部は磁性体から形成されている。これにより、支持体２０１の両側方に位置する磁石２０２の磁力により、第２光反射面２０６が鉛直上方（＋Ｚ方向）を向いた状態で固定されることとなる。なお、ユーザが回転レバー２０４を、磁力を超える力で回転した場合には、支持体２０１は第２筐体２００に対して、第２光反射面２０６の延在方向（Ｙ方向）に平行な軸を回転軸として回転可能である。 The light reflecting portion 113 is formed of an arbitrary material having high heat resistance, and is formed of, for example, a metal such as brass, a resin material such as glass, or a fluororesin. Similarly, the support 201 is made of any material having high heat resistance, but at least both sides are made of a magnetic material. Accordingly, the second light reflecting surface 206 is fixed in a state in which the second light reflecting surface 206 faces vertically upward (+ Z direction) by the magnetic force of the magnet 202 positioned on both sides of the support 201. When the user rotates the rotary lever 204 with a force exceeding the magnetic force, the support 201 is parallel to the extending direction (Y direction) of the second light reflecting surface 206 with respect to the second housing 200. The shaft can be rotated as a rotation axis.
　第１光反射面１１１と第２光反射面２０６は、赤外線近傍の波長における反射効率が高くなるように形成されており、例えば、金等のメッキにより形成される。 The first light reflecting surface 111 and the second light reflecting surface 206 are formed so as to have high reflection efficiency at wavelengths in the vicinity of infrared rays, and are formed, for example, by plating with gold or the like.
　光ユニット１０１の底面１１４には、光透過性を有するカバーを更に備えてもよい。これにより、注射器３０１を溶融する際に発生する汚染成分が第１光反射面１１１や熱線性光源１１２の表面に付着し、光反射効率や光透過効率が低下するのを防ぐことができる。カバーは石英等の耐熱性、光透過性の高い材料から構成されるのが望ましい。カバーに付着した汚染成分は、メンテナンス時に容易に拭き取ることが可能である。また、カバーには通気口を設け、光反射部１１３の内外で気圧の差が生じないようにする。 The bottom surface 114 of the optical unit 101 may further include a light transmissive cover. Thereby, it is possible to prevent contamination components generated when the syringe 301 is melted from adhering to the surfaces of the first light reflecting surface 111 and the heat ray light source 112 and reducing the light reflecting efficiency and the light transmitting efficiency. The cover is preferably made of a heat-resistant and light-transmitting material such as quartz. Contaminating components adhering to the cover can be easily wiped off during maintenance. Further, a vent is provided in the cover so that a difference in atmospheric pressure does not occur between the inside and outside of the light reflecting portion 113.
　光ユニット１０１と支持体２０１を図２に示すように構成することにより、第１焦点１２２に位置する熱線性光源１１２から出射された光の大部分は、第１光反射面１１１で反射し第２焦点１２３に集光される。また、第２焦点１２３から逸れた一部分の光は第２光反射面２０６で反射され第２焦点１２３近傍に集光される。これにより、第２焦点１２３に載置した注射器３０１に光が照射され、加熱されて、注射器３０１が溶融することとなる。 By configuring the optical unit 101 and the support body 201 as shown in FIG. 2, most of the light emitted from the thermal linear light source 112 located at the first focal point 122 is reflected by the first light reflecting surface 111 and the first light reflecting surface 111 is reflected. The light is collected at two focal points 123. Further, a part of the light deviating from the second focal point 123 is reflected by the second light reflecting surface 206 and collected near the second focal point 123. Thereby, the syringe 301 placed on the second focal point 123 is irradiated with light and heated, and the syringe 301 is melted.
　図３は、光ユニット１０１の移動を説明するための図である。注射器３０１は、支持体２０１の中央の第２光反射面２０６の上方に載置されるが、回転レバー２０４に近い図面左方に注射器３０１のシリンジが位置し、反対側の図面右方に注射針が位置する。つまり、注射針が＋Ｙ方向を向くように載置される。 FIG. 3 is a diagram for explaining the movement of the optical unit 101. The syringe 301 is placed above the second light reflecting surface 206 in the center of the support 201, but the syringe of the syringe 301 is located on the left side of the drawing near the rotation lever 204, and the injection is on the right side of the opposite side of the drawing. The needle is located. That is, the injection needle is placed so as to face the + Y direction.
　光ユニット１０１は光の照射を開始すると、図３の矢印で示すように、第１光反射面１１１の扁長楕円体の第２焦点１２３が注射器３０１の中心軸に位置する状態を保ちつつ、第２光反射面２０６の延在方向（Ｙ方向）に沿って、注射器３０１の注射針の針先端からシリンジの端部に向かって、－Ｙ方向に一定速度で移動する。 When the light unit 101 starts irradiating light, as shown by the arrow in FIG. 3, while maintaining the state where the second focal point 123 of the oblong ellipsoid of the first light reflecting surface 111 is located on the central axis of the syringe 301, Along the extending direction (Y direction) of the second light reflecting surface 206, the syringe 301 moves at a constant speed in the -Y direction from the needle tip of the injection needle of the syringe 301 toward the end of the syringe.
　具体的には、光ユニット１０１は、吊り下げ部１０２にＹ方向に平行移動可能に吊り下げられており、また、Ｙ方向に備えられたボールネジ１０３に嵌合するネジ溝が形成された支持部材を上部に備えている。ボールネジ１０３をモータで、一定角速度で回転させることにより、光ユニット１０１はボールネジ１０３に沿って一定速度で直線運動する。 Specifically, the optical unit 101 is suspended from the suspension part 102 so as to be movable in parallel in the Y direction, and the support member is formed with a screw groove that fits into the ball screw 103 provided in the Y direction. At the top. By rotating the ball screw 103 with a motor at a constant angular speed, the optical unit 101 moves linearly along the ball screw 103 at a constant speed.
　図１に戻って、他の構成を説明する。冷却ファン１０４は、図１に示すように、光ユニット１０１の上方に備えられ、光ユニット１０１を冷却するための空気を外部から吸い込んで、光ユニット１０１に向けて下方に空気を放出する。冷却ファン１０４は、第１筐体１００に対して位置を固定してもよい。あるいは、冷却ファン１０４は、光ユニット１０１に対して位置を固定することにより、光ユニット１０１と一緒にボールネジ１０３に沿って、直線運動するようにしてもよい。 Referring back to FIG. 1, another configuration will be described. As shown in FIG. 1, the cooling fan 104 is provided above the optical unit 101, sucks in air for cooling the optical unit 101 from the outside, and releases the air downward toward the optical unit 101. The position of the cooling fan 104 may be fixed with respect to the first housing 100. Alternatively, the cooling fan 104 may move linearly along the ball screw 103 together with the optical unit 101 by fixing the position with respect to the optical unit 101.
　排気ファン１０５は、注射器３０１を加熱処理することにより発生する汚染物質を含む空気を第１筐体１００の外に排出させる。排気ファン１０５から放出される空気の流路にはフィルタを備えており、汚染物質をフィルタで除去した空気を第１筐体１００の外部空間に放出する。 The exhaust fan 105 discharges air containing contaminants generated by heat-treating the syringe 301 to the outside of the first housing 100. A flow path of air discharged from the exhaust fan 105 is provided with a filter, and air from which contaminants have been removed by the filter is discharged to the external space of the first housing 100.
　制御部１０６は、第１筐体１００の外部に備えた制御スイッチの操作に基づいて、光ユニット１０１の直線運動を開始、停止させ、また、光ユニット１０１の熱線性光源１１２への電力供給の制御を実行する。 The control unit 106 starts and stops the linear motion of the optical unit 101 based on the operation of a control switch provided outside the first housing 100, and supplies power to the heat-linear light source 112 of the optical unit 101. Execute control.
　以上のように構成された加熱処理装置１の動作について、詳細に説明する。 The operation of the heat treatment apparatus 1 configured as described above will be described in detail.
　図４は、加熱処理装置１の第２筐体２００を引き出した状態を示す図である。まず、ユーザは、加熱処理装置１の第１筐体１００から、取っ手２０３をもって第２筐体２００を－Ｙ方向に引き出す。このとき、支持体２０１の少なくとも両側部が磁性体から構成されているため、支持体２０１の両側方に位置する磁石２０２の磁力により、両側部が磁石２０２に引きつけられている。これにより、第２光反射面２０６が形成された支持体２０１の上面が鉛直上方（＋Ｚ方向）を向いた状態で固定されている。 FIG. 4 is a diagram illustrating a state in which the second casing 200 of the heat treatment apparatus 1 is pulled out. First, the user pulls the second casing 200 from the first casing 100 of the heat treatment apparatus 1 with the handle 203 in the −Y direction. At this time, since at least both sides of the support 201 are made of a magnetic material, both sides are attracted to the magnet 202 by the magnetic force of the magnet 202 located on both sides of the support 201. Thereby, the upper surface of the support body 201 on which the second light reflection surface 206 is formed is fixed in a state in which the upper surface is directed vertically upward (+ Z direction).
　次に、ユーザは、第２筐体２００内の支持体２０１の支持片２０５上に、使用済みの注射器３０１を載置する。このとき注射針が＋Ｙ方向を向くように載置する。その後、第２筐体２００を第１筐体１００内に戻す。 Next, the user places the used syringe 301 on the support piece 205 of the support 201 in the second housing 200. At this time, the syringe needle is placed so as to face the + Y direction. Thereafter, the second housing 200 is returned into the first housing 100.
　加熱処理装置１の光ユニット１０１は、初期状態において、注射器３０１の注射針の針先端、又は、針先端より＋Ｙ方向にずれた点に第２焦点が位置するように配置されている。ユーザが第１筐体１００の外部に備えた制御スイッチを操作すると、その操作に基づいて、冷却ファン１０４と排気ファン１０５が駆動し、その後、制御部１０６が加熱処理の制御を開始する。 In the initial state, the optical unit 101 of the heat treatment apparatus 1 is arranged such that the second focal point is located at the needle tip of the injection needle of the syringe 301 or a point shifted in the + Y direction from the needle tip. When the user operates a control switch provided outside the first housing 100, the cooling fan 104 and the exhaust fan 105 are driven based on the operation, and then the control unit 106 starts controlling the heat treatment.
　まず、制御部１０６は熱線性光源１１２に電力の供給を開始する。図５は、熱線性光源１１２への供給電力値の変化を示すグラフである。図５に示すように針先端に第２焦点があるときは、高出力の電力を供給する。高出力の電力は例えば約３００Ｗである。 First, the control unit 106 starts supplying power to the thermal linear light source 112. FIG. 5 is a graph showing changes in the power supply value to the heat-linear light source 112. As shown in FIG. 5, when the second focal point is at the tip of the needle, high output power is supplied. The high output power is about 300 W, for example.
　制御部１０６は電力の供給開始後、ボールネジ１０３を正方向に回転させる。ボールネジ１０３の正方向の回転により、光ユニット１０１は－Ｙ方向に直線移動する。そして、図５に示すように針先端と針基の中間位置に第２焦点が来たとき、電力を低出力に低下させる。低出力の電力は例えば約１００Ｗである。 The control unit 106 rotates the ball screw 103 in the forward direction after the start of power supply. As the ball screw 103 rotates in the positive direction, the optical unit 101 moves linearly in the −Y direction. Then, as shown in FIG. 5, when the second focal point comes to an intermediate position between the needle tip and the needle base, the power is reduced to a low output. The low output power is about 100 W, for example.
　ここで、注射針は、光ユニット１０１が直線移動しながら熱線性光源１１２から照射される光及び第１光反射面１１１又は第２光反射面２０６で反射されて照射される光により加熱され針先端が溶融して鈍化する。また、注射針は金属から構成されているため、熱伝導率が高く、注射針の熱が針基及びシリンジの方に短時間で伝搬する。 Here, the injection needle is heated by the light irradiated from the heat ray light source 112 while the optical unit 101 moves linearly and the light reflected and irradiated by the first light reflecting surface 111 or the second light reflecting surface 206. The tip melts and blunts. Further, since the injection needle is made of metal, the heat conductivity is high, and the heat of the injection needle propagates toward the needle base and the syringe in a short time.
　よって、第２焦点が針先端と針基の中間位置にあるときには既に、針の熱がシリンジに十分に伝搬されており、シリンジは溶融される。このため、第２焦点が針先端と針基の中間位置にあるとき以降の供給電力レベルは、シリンジの溶融が完了するまで冷却ファン１０４によりシリンジの溶融点以下に冷却されない程度の電力で十分と言える。 Therefore, when the second focal point is at an intermediate position between the needle tip and the needle base, the heat of the needle is already sufficiently transmitted to the syringe, and the syringe is melted. For this reason, the power supply level after the second focal point is at an intermediate position between the needle tip and the needle base is sufficient with power that is not cooled below the melting point of the syringe by the cooling fan 104 until the syringe is completely melted. I can say that.
　そして、第２焦点がシリンジの端部、又は、端部より－Ｙ方向にずれた箇所まで達したところで、制御部１０６は熱線性光源１１２への電力供給を停止し、光ユニット１０１を＋Ｙ方向に移動させ、初期状態の位置まで戻して停止する。その後予め定めた時間、冷却ファン１０４と排気ファン１０５を駆動させた後に停止する。 When the second focal point reaches the end of the syringe or a position shifted in the −Y direction from the end, the control unit 106 stops the power supply to the heat ray light source 112 and moves the optical unit 101 in the + Y direction. Move to, return to the initial position and stop. Thereafter, the cooling fan 104 and the exhaust fan 105 are driven for a predetermined time and then stopped.
　全ての動作が停止すると、ユーザは、第２筐体２００の取っ手２０３を－Ｙ方向に引いて第２筐体２００を引き出す。このとき、第２筐体２００において、支持体２０１は、第２光反射面２０６が形成された上面が鉛直上方（＋Ｚ方向方向）を向いて固定された状態を保っている。 When all the operations are stopped, the user pulls the second casing 200 by pulling the handle 203 of the second casing 200 in the −Y direction. At this time, in the second housing 200, the support 201 maintains a state in which the upper surface on which the second light reflecting surface 206 is formed is fixed vertically upward (in the + Z direction).
　支持体２０１は、磁石２０２の磁力より勝る力で回転レバー２０４を回転させることにより、傾けることができる。図６Ａは、上方を向いた支持体２０１を示す図であり、図６Ｂは、側方を向いた支持体２０１を示す図である。加熱処理後に第２筐体２００を引き出した際には、支持体２０１の上面は図６Ａに示すように鉛直上方を向いている。その状態からユーザが回転レバー２０４を回転させることにより、図６Ｂのように支持体２０１は回転し、支持体２０１の上面が側方を向く。例えば、支持体２０１の上面は、水平面に対して１１０度の角度まで回転する。 The support 201 can be tilted by rotating the rotary lever 204 with a force that exceeds the magnetic force of the magnet 202. FIG. 6A is a diagram showing the support 201 facing upward, and FIG. 6B is a diagram showing the support 201 facing side. When the second housing 200 is pulled out after the heat treatment, the upper surface of the support 201 faces vertically upward as shown in FIG. 6A. When the user rotates the rotary lever 204 from this state, the support 201 rotates as shown in FIG. 6B, and the upper surface of the support 201 faces sideways. For example, the upper surface of the support 201 rotates to an angle of 110 degrees with respect to the horizontal plane.
　支持体２０１の回転により、支持片２０５の上に載置されていた加熱処理後の注射器３０１は鉛直下方に落下する。予め支持体２０１の下方に保管容器を配置させておくことにより、ユーザが注射器３０１に触れることなく保管容器に加熱処理後の注射器３０１を格納することができる。 The rotation of the support 201 causes the syringe 301 after heat treatment placed on the support piece 205 to fall vertically downward. By arranging the storage container below the support 201 in advance, the user can store the syringe 301 after the heat treatment in the storage container without touching the syringe 301 by the user.
　このようにして、注射器３０１を加熱処理することにより、注射針及びシリンジが一度溶融して凝固した状態で保管容器に格納することができる。処理後の注射器３０１は、注射針の尖部が鈍化され、注射器３０１全体が滅菌処理され、注射器３０１の容積が低減された状態となっている。したがって、注射器３０１が廃棄されるまでの安全性を向上させるとともに、減容量化することができる。 In this way, by performing the heat treatment on the syringe 301, the injection needle and the syringe can be once melted and solidified and stored in the storage container. In the treated syringe 301, the tip of the injection needle is blunted, the entire syringe 301 is sterilized, and the volume of the syringe 301 is reduced. Therefore, the safety until the syringe 301 is discarded can be improved and the volume can be reduced.
　以上説明したように、本実施形態において、光ユニット１０１は、扁長楕円体の表面の一部となる形状の第１光反射面１１１を内側に形成した光反射部１１３と、扁長楕円体の第１焦点に配置された熱線性光源１１２と、から構成される。注射器３０１は、第２筐体２００内の支持体２０１の第２光反射面２０６上の、扁長楕円体の第２焦点に載置される。そして、光ユニット１０１は注射器３０１の延在方向に沿って移動しつつ、熱線性光源１１２の光を第１光反射面１１１又は第２光反射面２０６で反射させて照射させ、注射器３０１を加熱することとした。これにより、熱線性光源１１２から出射する光のほぼ全てが注射器３０１に照射され、高効率で低コストの加熱処理が可能となる。 As described above, in the present embodiment, the optical unit 101 includes the light reflecting portion 113 in which the first light reflecting surface 111 having a shape that becomes a part of the surface of the oblong ellipsoid is formed, and the oblong ellipsoid. And a heat linear light source 112 arranged at the first focal point. The syringe 301 is placed on the second focal point of the oblong ellipsoid on the second light reflecting surface 206 of the support 201 in the second housing 200. Then, the optical unit 101 moves along the extending direction of the syringe 301, reflects the light of the heat ray light source 112 by the first light reflecting surface 111 or the second light reflecting surface 206, and heats the syringe 301. It was decided to. Thereby, almost all of the light emitted from the heat ray light source 112 is irradiated to the syringe 301, and a heat treatment with high efficiency and low cost becomes possible.
　このように本発明は、加熱処理装置が、扁長楕円体の表面の一部となる形状の第１光反射面を内側に形成した光反射部と、扁長楕円体の第１焦点に配置された熱線性光源と、からなる光ユニットと、扁長楕円体の第２焦点に加熱対象物が位置するように加熱対象物を支持し、加熱対象物に対向する面に第２光反射面を有する支持体と、を備え、光ユニットが、加熱対象物の延在方向に平行に移動して、加熱対象物を加熱処理することとした。これにより、加熱対象物の高効率で低コストの加熱処理が可能となる。 As described above, in the present invention, the heat treatment apparatus is arranged at the light reflecting portion in which the first light reflecting surface having a shape that becomes a part of the surface of the oblong ellipsoid is formed, and the first focal point of the oblong ellipsoid. And a second light reflecting surface on the surface facing the heating object so that the heating object is positioned at the second focal point of the oblong ellipsoid. The optical unit moves in parallel with the extending direction of the heating object, and heats the heating object. Thereby, high-efficiency and low-cost heat treatment of the object to be heated becomes possible.

Accordingly, the second housing 200 may be used properly. Thereby, regardless of the size or shape of the heating object, the second focus can be reliably adjusted to the center of the heating object, and the heating efficiency can be further improved.
　また、上記実施形態では、第２筐体２００内の支持体２０１に固定された注射器３０１に対して光ユニット１０１を移動させて加熱するとしたが、光ユニット１０１を固定して支持体２０１を移動させるようにしてもよい。この場合、第２筐体２００に支持体２０１を平行移動させる機構を備える。 In the above embodiment, the optical unit 101 is moved and heated with respect to the syringe 301 fixed to the support body 201 in the second housing 200.
