【発明の詳細な説明】
本発明は医療用混合針の製造方法に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a medical mixing needle.
発明の目的：従来の混合針は金属製管内に二通

用いて製造されていた、そのために刃先をピン栓

あつた。これらの点を改めて利用しやすい混合針
を製造することを本発明の目的とした。 Purpose of the invention: Conventional mixing needles were manufactured using a separation plate to form two passages in a metal tube. In some cases, the separator plate, which is a part of the separator plate, scrapes a portion of the stopper and gets stuck in the passageway, thereby interfering with the mixing of medicines. Furthermore, it seemed that providing and manufacturing the separator plate increased the number of man-hours and was too expensive. It is an object of the present invention to take these points into consideration and manufacture a mixing needle that is easy to use.

両面からカシメ圧力を与えて固着７ａする。 Structure of the invention: An embodiment of the manufacturing method will be described in detail with reference to the drawings. Regarding FIG. 1, in a metal pipe 1 having an arbitrary length L, there is a two-pass or multi-pass 2n formed by extrusion molding or injection molding and having an outer diameter slightly smaller than the inner diameter of the pipe 1. A tube body 1 of a mixing needle is manufactured by attaching a plastic tube 2 having a diameter. The tube 2 is used to form the cutting edge avoiding the separation plate described above, and to reduce the space on the blade surface so that a part of the bottle stopper is not scraped. There is no need to decide whether the machining linearity is good or not. Regarding FIG. 2, it is a sectional view taken along the line AA in FIG. 1. Referring to FIG. 3, the diameter of the tube 1 is reduced by the diameter reducing device 3 so that the metal pipe 1 and the tube 2 are in close contact with each other.
Then, a needle body 6 having a desired dimension 1 and a desired angle θ is manufactured by a cutting device connected to the diameter reducing device 3 and capable of changing the cutting angle. Regarding FIG. 4, a pair of holding parts 7 made of metal or plastic are provided in the central part of the needle body 6, and an adhesive is interposed therebetween.
It is fixed 7a by applying crimp pressure from both sides.

の採用で工数の軽減が可能になつた。 Effects of the invention: As described above, the needle body 6 does not strictly require machining linearity for the multi-passage 2n during the process, and the cutting device 4 is connected to the diameter reducing device 3, and the cutting edge is 5, each blade surface and each passage coincide. Further, the separation structure 2w forming the multi-passage 2n forms a part of each blade surface and forms a bridge on the blade surface, making it difficult for a part of the bottle stopper to be scraped off. In terms of manufacturing man-hours, the tube 2
The adoption of this has made it possible to reduce man-hours.
