Description

本発明は、アンビルに装着した押えにより、溶着時にアンビルの側部の被溶着物を押えるようにした超音波溶着器に関するものである。   The present invention relates to an ultrasonic welder in which a workpiece attached to a side portion of an anvil is pressed during welding by a presser mounted on the anvil.

従来、図５及び図６に示すように、ハンドピース１の一端に超音波振動子２のホーン２ａの端部が突出され、ハンドピース１の側部にアンビル部３の摺動部材３ａが摺動可能に装着され、摺動部材３ａからアンビル３ｂがほぼ垂直に形成され、アンビル３ｂの端部は超音波振動子２のホーン２ａの端部と接触するように構成され、ハンドピース１の両側面に装着された回動軸４で回動部材５の三角部材５ａの頂点部分が支持され、又、回動部材５は三角部材５ａからハンドピース１の下方に斜めにレバー５ｂが形成され、さらに、回動部材５の三角部材５ａの底部近傍に駆動軸６が固着され、又、アンビル部３の摺動部材３ａを貫通して支持軸７が摺動部材３ａに固着され、駆動軸６と支持軸７の間にＵ字状のバネ８が装着され、又、ハンドピース１の側部に発振スイッチ９が装着され、レバー３ｂに装着した突出部５ｃで発振スイッチ９を押すようにした超音波溶着器が提案されている。   Conventionally, as shown in FIGS. 5 and 6, the end of the horn 2 a of the ultrasonic transducer 2 protrudes from one end of the handpiece 1, and the sliding member 3 a of the anvil portion 3 slides on the side of the handpiece 1. The anvil 3b is mounted so as to be movable, and the anvil 3b is formed substantially vertically from the sliding member 3a. The end of the anvil 3b is configured to come into contact with the end of the horn 2a of the ultrasonic vibrator 2, and The rotating shaft 4 mounted on the surface supports the apex portion of the triangular member 5a of the rotating member 5, and the rotating member 5 is formed with a lever 5b obliquely below the handpiece 1 from the triangular member 5a. Further, the drive shaft 6 is fixed to the vicinity of the bottom of the triangular member 5 a of the rotating member 5, and the support shaft 7 is fixed to the slide member 3 a through the sliding member 3 a of the anvil portion 3. A U-shaped spring 8 is mounted between the support shaft 7 and the hand. Over side to the oscillation switch 9 of the scan 1 is mounted, ultrasonic welding instrument which has to press the oscillation switch 9 protruding portion 5c attached to the lever 3b are proposed.

しかしながら、輸血及び採血又は薬品等のチューブ溶着の場合、この超音波溶着器では、被溶着物１０の内部の血液や薬品がアンビルと超音波振動子との溶着部で被溶着物を溶着する時、溶着部で発生する熱や振動により、血液や薬品が凝固したり、溶解したり、破壊されたりするという問題がある。
特願２００４−２２５２２２６ However, in the case of blood transfusion, blood sampling, or tube welding of chemicals or the like, in this ultrasonic welder, when blood or chemicals inside the welded material 10 welds the welded material at the welded portion between the anvil and the ultrasonic vibrator. There is a problem in that blood and chemicals are coagulated, dissolved, or destroyed by heat and vibration generated in the welded part.
Japanese Patent Application No. 2004-2252226

解決しようとする問題点は、従来の超音波溶着器では、被溶着物の内部に血液や薬品が入れられている場合には、溶着部で発生する熱や振動により、血液や薬品が凝固したり、溶解したり、破壊されたりするという問題がある。   The problem to be solved is that in conventional ultrasonic welders, when blood or chemicals are placed inside the object to be welded, the blood and chemicals are solidified by heat and vibration generated in the welded part. There is a problem of being melted or destroyed.

本発明では、ハンドピースは超音波振動子を内蔵し、超音波振動子のホーンの先端が端部に突出され、アンビル部はハンドピースの側部に摺動部材を装着し、摺動部材から突出するアンビルの接触部が超音波振動子のホーンと対向するように装着され、コ字型の押えはアンビル部のアンビルに嵌合され、アンビルより突出するネジはコ字型の押えを貫通してアンビルに固着され、バネはネジの頭部と押えの間に介在されてなり、被溶着物を溶着する時に、バネによって押えを押圧して被溶着物を押圧し、アンビルが被溶着物を溶着するために超音波振動子に近づく時、押えがアンビルの側部の被溶着物を押えつけるものである。   In the present invention, the handpiece has a built-in ultrasonic transducer, the tip of the horn of the ultrasonic transducer is projected at the end, the anvil portion is mounted with a sliding member on the side of the handpiece, The protruding part of the anvil is mounted so that it faces the horn of the ultrasonic vibrator. The U-shaped presser is fitted to the anvil of the anvil part, and the screw protruding from the anvil penetrates the U-shaped presser. The spring is interposed between the head of the screw and the presser foot, and when welding the welded object, the presser is pressed by the spring to press the welded object, and the anvil removes the welded object. When approaching the ultrasonic vibrator for welding, the presser presses the object to be welded on the side of the anvil.

本発明の超音波溶着器は、被溶着物に血液や薬品が入れられている場合に、溶着時に、被溶着物を溶着するためにアンビルが超音波振動子に近づく時、バネによって押えを押圧して被溶着物を押圧し、被溶着物内に入れられている血液や薬品をアンビルの側部から押しやることにより、溶着部で発生する熱や振動により、アンビルと超音波振動子の側部の血液や薬品が凝固したり、溶解したり、破壊されたりすることがないという利点がある。   The ultrasonic welder of the present invention presses the presser with a spring when the anvil approaches the ultrasonic vibrator in order to weld the welded material when blood or chemicals are put in the welded material. Then, the side of the anvil and the ultrasonic transducer is pressed by the heat and vibration generated in the welded portion by pressing the welded material and pushing the blood and chemicals contained in the welded material from the side of the anvil. There is an advantage that the blood and chemicals of the body are not coagulated, dissolved or destroyed.

図１は本発明の実施例の超音波溶着器のアンビルとホーン部分の斜視図で、アンビル３ｂにコ字型の押え１１が嵌合され、コ字型の押え１１を貫通してネジ１２の先端がアンビル３ｂに固着され、ネジ１２の頭部１２ａはコ字型の押え１１を貫通して突出し、ネジ１２の頭部１２ａと押え１１の間にバネ１３を介在させることにより、コ字型の押え１１はバネ１３によって常にアンビル３ｂと接触され、コ字型の押え１１の下端１１ａはアンビル３ｂの下端３ｃと平行になるように構成されている。   FIG. 1 is a perspective view of an anvil and a horn portion of an ultrasonic welder according to an embodiment of the present invention. A U-shaped presser 11 is fitted to the anvil 3b, and the U-shaped presser 11 is passed through the screw 12. The tip of the screw 12 is fixed to the anvil 3b, the head 12a of the screw 12 protrudes through the U-shaped presser 11, and the spring 13 is interposed between the head 12a of the screw 12 and the presser 11, so that the U-shaped The presser foot 11 is always in contact with the anvil 3b by the spring 13, and the lower end 11a of the U-shaped presser foot 11 is configured to be parallel to the lower end 3c of the anvil 3b.

このように構成された本実施例の超音波溶着器では、図５及び図６に示すように、ハンドピース１の側面に回動可能に装着された回動部材５のレバー５ｂをハンドピース１の方向に押し付けると、回動部材５の三角部材５ａに固着された駆動軸６でＵ字状のバネ８がバネの力に抗して押され、バネ８が戻る力によって、アンビル部３の摺動部材３ａに固着された支持軸７が押されるので、支持軸７はバネ８の戻る力によって移動され、アンビル部３の摺動部材３ａと一体となったアンビル３ｂの端部が超音波振動子２のホーン２ａの方向に移動するが、図２に示すように、アンビル３ｂと超音波振動子２のホーン２ａ及び支持部材１５は血液や薬品１４が封入された被溶着物１０を挟んで対向して配置され、次に、図３に示すように、被溶着物１０がアンビル３ａ及び押え１１によって押圧されると、押えられた部分の被溶着物１０内の血液や薬品１４が移動して、押圧部分の血液や薬品１４が押し退けられ、さらに、アンビル３ａが超音波振動子２のホーン２ａの方へ移動すると、図４に示すように、バネ１３によって押え１１と支持部材１５は血液や薬品が押し退けた状態で保持され、アンビル３ａと超音波振動子２のホーン２ａで被溶着物１０を溶着する時に、アンビル３ａとホーン２ａの間に発生する振動や熱は押え１１で押圧している被溶着物１０を伝わって血液や薬品１４に伝達されないので、血液や薬品１４が凝固したり、溶解したり、破壊されたりすることがないという利点がある。   In the ultrasonic welder of this embodiment configured as described above, as shown in FIGS. 5 and 6, the lever 5 b of the rotating member 5 rotatably mounted on the side surface of the handpiece 1 is used as the handpiece 1. The U-shaped spring 8 is pushed against the spring force by the drive shaft 6 fixed to the triangular member 5a of the rotating member 5, and the spring 8 returns to the anvil portion 3 by the force of returning. Since the support shaft 7 fixed to the sliding member 3a is pushed, the support shaft 7 is moved by the return force of the spring 8, and the end of the anvil 3b integrated with the sliding member 3a of the anvil portion 3 is ultrasonic. As shown in FIG. 2, the anvil 3b, the horn 2a of the ultrasonic transducer 2 and the support member 15 sandwich the object to be welded 10 in which blood or a medicine 14 is sealed, as shown in FIG. Placed next to each other and then welded as shown in FIG. When 10 is pressed by the anvil 3a and the presser 11, the blood and the medicine 14 in the welded part 10 in the pressed part move, and the blood and the medicine 14 in the pressed part are pushed away. When moving toward the horn 2a of the sound wave vibrator 2, as shown in FIG. 4, the presser 11 and the support member 15 are held by the spring 13 in a state where the blood and the medicine are pushed away, and the anvil 3a and the ultrasonic vibrator 2 are moved. The vibration and heat generated between the anvil 3a and the horn 2a are not transmitted to the blood and the medicine 14 through the welding object 10 pressed by the presser 11 when the object 10 is welded by the horn 2a. There is an advantage that the chemicals 14 and the chemicals 14 are not solidified, dissolved or destroyed.

なお、上記実施例では、アンビル３ａにネジ１２を２本用いた例を示したが、ネジ１２は１本でもよいし、３本以上でもよい。   In the above embodiment, an example in which two screws 12 are used for the anvil 3a has been shown. However, the number of the screws 12 may be one, or three or more.
