本発明は翼付針の新規な製造法に関する。さらに詳しく
は、高速連続生産が可能で製造コストの低い翼付針の製
造法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel method for manufacturing winged needles. More specifically, the present invention relates to a method for manufacturing winged needles that enables high-speed continuous production and has low manufacturing costs.

備投資が必要であり、この点でも従来の方法はコスト的
に不利であった。Conventionally, winged needles have often been used in fields such as infusions, and the following two methods for manufacturing them are common. Specifically, there are two methods: a method in which the needle and tube are bonded to a wing portion formed by injection molding, and a method in which the needle is set in a mold during the injection molding process, the needle is fixed at the same time as the wing portion is molded, and then the tube is bonded. However, since all of these methods include an injection molding process or a bonding process using an adhesive, they are not suitable for high-speed continuous production. In other words, in injection molding, it is practically difficult to reduce the molding cycle to 20 seconds or less, and if part of the process includes an injection molding process, it is difficult to automate the entire process. . Therefore, there was a limit to the reduction in manufacturing costs. Additionally, injection molding requires a large investment in equipment, and in this respect too, conventional methods are disadvantageous in terms of cost.
本発明者は高周波加熱を利用した成形法を採用すること
により、従来技術の有するこれらの問題点を解決し得る
ことを見出し、特願昭５８−１２８６４６号として先に
特許出願を行なった。そしてかがる技術についてさらに
検討を進めた結果、針を金型にセットする際に特定の位
置関係にこれらを保持した場合にのみ良好な製品が得ら
れることを見い出し、本発明に到達した。The inventor of the present invention found that these problems of the prior art could be solved by adopting a molding method using high-frequency heating, and filed a patent application in Japanese Patent Application No. 128,646/1983. As a result of further investigation into the darning technique, the inventors discovered that a good product could only be obtained if the needles were held in a specific positional relationship when they were set in the mold, leading to the present invention.
すなわち本発明は、医療用針の基部を挿入した合成樹脂

針を製造するに際し針の基端部を金型側面よりも外側に
位置させて高周波加熱を行なうことを特徴とする翼付針
の製造法である。That is, in the present invention, a synthetic resin tube body into which the base of a medical needle is inserted and a synthetic resin for forming wing portions are set in a mold,
The synthetic resin is heated in a mold by high-frequency current to form wings, and when integrated with the needle and tube body to produce a winged needle, the proximal end of the needle is positioned outside the side of the mold. This method of manufacturing winged needles is characterized by performing high-frequency heating.

より、良好な翼付針を能率よく製造することができる。Hereinafter, the present invention will be explained based on the drawings. FIG. 1 is a perspective view showing the arrangement of a needle, a tube body, a wing forming material, and a mold before molding in an embodiment of the present invention. As shown in the figure, synthetic resin sheets 3.3, which are wing forming materials, are placed on both sides of the tube body 2, and sandwiched from both sides by molds 4.4. FIG. 2 is a diagram showing the state of the needle 1, tube body 2, sheet 3, and mold 4 immediately before molding, and the sheet 3/ and mold 4' are omitted. As shown in the figure, the proximal end 1.1 of the needle 1 is located outside the side surface 41 of the mold 4. By positioning it in this way and performing high-frequency heating, a good winged needle can be manufactured efficiently.

しないために好ましい。On the other hand, if the proximal end of the needle is located within the mold, the tube body 2 will be deformed or blocked when high-frequency heating is performed, making it impossible to obtain a product that can withstand practical use. The distance between the proximal end of the needle and the side surface of the mold is not particularly limited;
About 0.5 to 1OM is preferably used. After sandwiching the needle, tube body, and sheet from both sides with a mold, when a high-frequency current is passed through the mold using the mold as an electrode, the sheet and tube body are heated due to dielectric loss, softening, and completely melting to form wings. At the same time, the wing portion and the tube body are integrated. Fixation of the needle and the tube body can be achieved by high-frequency heating of the tube body using the needle as one electrode before or after forming the wing portion, or during the formation of the wing portion. Also at this time, it is preferable to position the proximal end of the needle outside the side surface of the mold that will serve as the other electrode, in order to prevent the tube body from being deformed or blocked.
第３図は、このようにして得られた翼付針の一実施例を

上述の例においては翼部形成材料として、合成樹脂シー
トを２枚使用したが、１枚だけを使用してもよく、シー
ト状以外の形状であってもよい。In the above example, two synthetic resin sheets were used as the wing forming material, but only one synthetic resin sheet may be used, and the material may have a shape other than the sheet shape.

。The conditions for high-frequency heating in the present invention vary greatly depending on the type and size of the material used, so conditions are selected as appropriate. Further, the base of the needle to be used may be coated, the surface may be roughened, or grooves or protrusions may be provided in order to improve the strength of fixing the needle to the tube body. Further, the mold may be of a one-sided type or a multiple-piece type.

らの効果がきわめて顕著になる。In the present invention, the formation of the wings and the fixation of the needle and tube body are all performed by high-frequency heating, and there is no process such as adhesive bonding or injection molding. This makes it possible to significantly shorten the time, increase speed, and reduce manufacturing costs.Furthermore, it becomes possible for the first time to fully automate the entire process, and when fully automated, these effects become extremely noticeable.
本発明の方法は、医療用途に使用されるあらゆる翼付針

呼ばれる翼付静注針の製造に好適である。The method of the present invention can be applied to the production of any winged needles used for medical purposes, and is particularly suitable for the production of winged intravenous needles called scalp veins.
