この発明は容器から薬液等を取出す際に使用す
る医療針の製造法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a medical needle used when taking out a medical solution or the like from a container.
近時、この種の医療針として、第１図に示すよ
うに中空パイプの先端に形成された扁平鋭角部２
１と中空パイプの中空部内と連通する貫通孔２２
とを有するものが看られる。 Recently, as this type of medical needle, a flat acute angle part 2 formed at the tip of a hollow pipe as shown in Fig. 1 has been developed.
1 and a through hole 22 that communicates with the inside of the hollow pipe.
Those with this are seen.
そして、この医療針の扁平鋭角部２１は中空パ
イプの一端を扁平に潰して密着し、次いで、この
密着部分を鋭角になるように切断することにより
形成されている。 The flat, acute-angled portion 21 of this medical needle is formed by flattening one end of a hollow pipe, making it fit tightly, and then cutting this tightly-fitted portion to form an acute angle.
しかし、この従来の製造法（特開53―43992
号）は密着工程と切断工程との２工程が時を異な
らして行なわれ、また、これらの２工程により１
本の医療針しか製造されない為、効率が悪く、し
かも、中空パイプ一端の切断に伴ないスクラツプ
が生ずると云う欠点がある。この為、現実にはこ
の製造法による医療針の製造は行われていない。 However, this conventional manufacturing method (Japanese Patent Application Laid-Open No. 53-43992
No.), the two processes of adhesion and cutting are performed at different times, and these two processes
Since only regular medical needles are manufactured, efficiency is low, and there is a drawback that scrap occurs due to cutting of one end of the hollow pipe. For this reason, medical needles are not actually manufactured using this manufacturing method.
そこで、この発明は極めて効率良く、しかも、
スクラツプを生じさせることなく扁平鋭角部を加
工できるようにした医療針の製造法を目的として
提案するものであつて、中空パイプの中途を扁平
に潰して密着すると同時にこの扁平密着部分を斜
めに切断することを特徴とする医療針の製造法で
ある。 Therefore, this invention is extremely efficient and also
We propose a manufacturing method for medical needles that allows processing of flat, sharp corners without scraping.The purpose is to crush the middle of a hollow pipe into a flat shape, make a close contact with it, and at the same time cut the flat, close-contact part diagonally. This is a method for manufacturing medical needles characterized by:
以下、この発明に係る医療針の製造法の実施例
を図面に基づいて説明する。 Embodiments of the method for manufacturing a medical needle according to the present invention will be described below with reference to the drawings.
所定の間隔で中空部１と連通する貫通孔２，２
を２個所設けた中空パイプ３を自動整列機４に並
列に収容してプレス成形機５の加工部６まで１本
づつ送り込む。 Through holes 2, 2 communicate with the hollow part 1 at predetermined intervals.
Hollow pipes 3 provided with two positions are housed in parallel in an automatic alignment machine 4 and fed one by one to a processing section 6 of a press molding machine 5.
この中空パイプ３の加工位置としては、第３図
に示すように貫通孔２，２の略中間に位置決めさ
れる。 The processing position of this hollow pipe 3 is positioned approximately midway between the through holes 2, 2, as shown in FIG.
そして、この位置決めされた中空パイプ３の中
途は、ラム７が下降し、固定ダイ８，８、移動ダ
イ９，９により扁平に潰されて密着し、この扁平
密着部分１０が同時に固定ダイ８，８により斜め
に切断される。 Then, the ram 7 lowers the positioned midway of the hollow pipe 3, and the fixed dies 8, 8 and the movable dies 9, 9 crush the hollow pipe 3 flatly into close contact with each other. It is cut diagonally by 8.
この分離切断加工後、プレス成形機５から自動
的に取出されることにより２本の医療針１１，１
１が製造される。 After this separation and cutting process, the two medical needles 11 and 1 are automatically taken out from the press molding machine 5.
1 is produced.
以上のようにこの発明に係る医療針の製造法に
よれば、密着工程と切断工程とが同時に行なわれ
て扁平鋭角部が形成され、しかも、１本ではなく
２本の医療針の扁平鋭角部が同時に形成されて製
造されるので、極めて効率が良く、時間的にも経
済的にも優れた製造法である。 As described above, according to the method for manufacturing a medical needle according to the present invention, the adhesion process and the cutting process are performed at the same time to form a flat acute angle part, and moreover, the flat acute angle part of not one but two medical needles is formed. Since these are formed and manufactured at the same time, it is an extremely efficient manufacturing method that is excellent in terms of time and economy.
また、従来の製造法のように中空パイプ一端の
切断に伴なうスクラツプも生じないと云うことも
見逃すことのできない効果である。 Another advantage that cannot be overlooked is that there is no scrap caused by cutting one end of the hollow pipe, unlike in conventional manufacturing methods.
