【０００１】[0001]
本考案は、薬液バッグ、血液バッグ等の医療用バッグの口部に設けられる連通 部材の改良に関するもので、特に、射出成形により液体移送チュ−ブの装着溝を 一体に成形した連結筒内に、大径部の液体の流路の径を大きくし十分な流路を確 保できるようにした連通部材を提供するものである。 The present invention relates to an improvement of a communication member provided at the mouth of a medical bag such as a liquid medicine bag and a blood bag. It is intended to provide a communication member in which the diameter of the liquid flow path of the large diameter portion is increased to ensure a sufficient flow path.
【０００２】[0002]
連通ピ−スとして、従来から種々のものが提案されているが一般的には、たと えば第１０図に示すごとく、小径部２７が閉塞した硬質樹脂製の大径部２８に、 薄肉部２９を形成し、前記小径部２７を連結筒２５の外側から押し倒して折るよ うにしたものが使用されている。小径部２７の外径は液体移送チュ−ブ２２の内 径と同程度に形成されているので、小径部２７を切断した後、小径部２７が液体 移送チュ−ブ２２を塞いでしまうことがあった。 Various types of communication pieces have been conventionally proposed, but generally, as shown in FIG. 10, a thin portion 29 is formed on a large diameter portion 28 made of a hard resin in which a small diameter portion 27 is closed. Is used, and the small diameter portion 27 is pushed down from the outside of the connecting cylinder 25 to be folded. Since the outer diameter of the small diameter portion 27 is formed to be approximately the same as the inner diameter of the liquid transfer tube 22, the small diameter portion 27 may block the liquid transfer tube 22 after cutting the small diameter portion 27. there were.
【０００３】 小片である小径部２７に部分的に力を集中させることは、連結筒２５が比較的 肉厚であり、液体移送チュ−ブ２２の重量も加わることから、かなりの力が必要 であり、困難であった。例えば切断する方向によってしなるような感じがして実 際に切断する力以上に力を加える必要があった。To partially concentrate the force on the small diameter portion 27 which is a small piece, a considerable force is required because the connecting tube 25 is relatively thick and the weight of the liquid transfer tube 22 is added. Yes, it was difficult. For example, there was a feeling of bending depending on the cutting direction, and it was necessary to apply more force than the actual cutting force.
【０００４】 また小径部２７の外径は連結筒２５の内径よりも小さいので液体の流通中に開 口した大径部２８の流路を一時的に遮断する現象も時々みられ、流量の定常的維 持が困難であった。また大径部２８の液体の流路の径Ｄ６は、約４ｍｍ、薄肉部 ２９付近の液体流通口の径Ｄ５は、約２ｍｍに設定されているので、十分な流量 が確保できなかった。そこで本考案者は以上の課題を解決するため鋭意検討を重 ねた結果次の考案に到達した。Further, since the outer diameter of the small diameter portion 27 is smaller than the inner diameter of the connecting cylinder 25, the phenomenon of temporarily blocking the flow path of the large diameter portion 28 opened during the flow of the liquid is sometimes observed, and the steady flow rate is maintained. Was difficult to maintain. Further, since the diameter D6 of the liquid flow path of the large diameter portion 28 is set to about 4 mm and the diameter D5 of the liquid flow port near the thin portion 29 is set to about 2 mm, a sufficient flow rate cannot be secured. Therefore, the present inventor has made intensive studies to solve the above problems, and as a result, arrived at the next inventor.

【課題を解決するための手段】 本考案は、小径部２と大径部３が薄肉部４を介して一体に成形され、前記大径 部３の内部には径Ｄ２が３〜１０ｍｍに形成された液体流路８が形成され、前記 小径部２の先端に溝部６が形成されるとともに前方側面の長径Ｌ側に斜面５が形 成され、前記薄肉部４付近の液体流出口９の径Ｄ１が２〜５ｍｍに形成された連 通部材１を提供する。Means for Solving the Problems In the present invention, a small diameter portion 2 and a large diameter portion 3 are integrally formed via a thin portion 4, and a diameter D2 is formed in the inside of the large diameter portion 3 to be 3 to 10 mm. Is formed, a groove 6 is formed at the tip of the small diameter portion 2 and a slope 5 is formed on the major diameter L side of the front side surface, and the diameter of the liquid outlet 9 near the thin portion 4 is formed. A communication member 1 having D1 of 2 to 5 mm is provided.
【０００６】 また本考案は、小径部１２と大径部１３が薄肉部１４を介して一体に成形され 、前記大径部１３の内部には径Ｄ４が２ｍｍから３ｍｍに形成された液体流路１ ８が形成され、前記小径部１２の先端に溝部１６が形成されるとともに前方側面 の長径Ｌ側に斜面１５が形成され、かつ外周に翼部１７が形成され、前記薄肉部 １４付近の液体流出口１９の径Ｄ３が１．９ｍｍから２．２ｍｍに形成された連 通部材１１を提供する。Further, according to the present invention, the small-diameter portion 12 and the large-diameter portion 13 are integrally molded via the thin-walled portion 14, and the large-diameter portion 13 has a diameter D 4 of 2 mm to 3 mm. 18 is formed, a groove portion 16 is formed at the tip of the small diameter portion 12, a slope 15 is formed on the major diameter L side of the front side surface, and a wing portion 17 is formed on the outer periphery, so that liquid near the thin portion 14 is formed. The communication member 11 is provided in which the diameter D3 of the outflow port 19 is formed to be 1.9 mm to 2.2 mm.
【０００７】[0007]
図１は本考案の連通部材１の概略図で、図２は図１のＡ矢視図、図３は図２の Ｂ矢視図である。連通部材１は小径部２と大径部３を指圧で破断可能な薄肉部４ を介して一体に形成されている。大径部３は内部に液体の流量を十分に確保する ことができるように径Ｄ２が３ｍｍから１０ｍｍに形成された液体流路８が形成 されている。 1 is a schematic view of a communication member 1 of the present invention, FIG. 2 is a view taken in the direction of arrow A in FIG. 1, and FIG. 3 is a view taken in the direction of arrow B in FIG. The communicating member 1 is formed integrally with the small-diameter portion 2 and the large-diameter portion 3 via a thin-walled portion 4 that can be broken by finger pressure. A liquid passage 8 having a diameter D2 of 3 mm to 10 mm is formed inside the large diameter portion 3 so as to ensure a sufficient flow rate of the liquid.
【０００８】 小径部２は先端部に溝部６が形成されるとともに前方側面の長径Ｌ側に斜面５ が形成されている。先端部は長径Ｌが３ｍｍから５ｍｍ、短径Ｓが１ｍｍから３ ｍｍに形成される。The small-diameter portion 2 has a groove 6 formed at the tip and a slope 5 on the major axis L side of the front side surface. The tip has a major axis L of 3 mm to 5 mm and a minor axis S of 1 mm to 3 mm.
【０００９】 また前記薄肉部４付近の液体流出口９の径Ｄ１は、大径部３の液体流路８から 流入した液体の流量を確保できるように２ｍｍから５ｍｍに形成されている。径 Ｄ２とＤ１の比Ｒ1 （Ｒ1 ＝Ｄ2 ／Ｄ1 ）は径Ｄ２が大きければ１に近いほど液 体の流量を十分に確保することができる。Ｒ1 は１から１．３が好適である。Ｒ 1 が１．３より大きいと径Ｄ２の大口径を生かして液体の流量が十分に確保でき ないし、Ｒ1 が１より小さいと薄肉部４を介して小径部２を一体成形するのが困 難となるからである。Further, the diameter D1 of the liquid outlet 9 near the thin portion 4 is formed to be 2 mm to 5 mm so as to secure the flow rate of the liquid flowing from the liquid flow path 8 of the large diameter portion 3. Ratio R of diameter D2 and D11 (R1 = D2 / D1 The larger the diameter D2 is, the closer to 1 is, the more sufficient the flow rate of the liquid can be secured. R1 Is preferably 1 to 1.3. R 1 Is larger than 1.3, it is not possible to secure a sufficient flow rate of the liquid by taking advantage of the large diameter of D2.1 Is smaller than 1, it becomes difficult to integrally form the small diameter portion 2 through the thin portion 4.
【００１０】 使用に際しては薄肉部４を指圧で破断して前記液体流出口９を開口し、液体を 医療用バッグ側から、液体流路８、液体流出口９、小径部２の外周を経て液体移 送チュ−ブ側へ流出させる。液体の流量は大径部３の液体流路８、液体流出口９ より十分に確保でき、斜面５に沿って速かに排出することができる。In use, the thin portion 4 is broken by finger pressure to open the liquid outlet 9, and the liquid is passed from the medical bag side through the liquid flow path 8, the liquid outlet 9, and the outer periphery of the small diameter portion 2. Let it flow to the transfer tube side. The flow rate of the liquid can be sufficiently secured from the liquid flow path 8 and the liquid outlet 9 of the large diameter portion 3, and the liquid can be quickly discharged along the slope 5.
【００１１】 薄肉部４の破断角度θは図４（図１の矢印Ａの円内の一部拡大図）に示すよう に５０°に形成されている。これにより薄肉部４の破断面（開口断面）をほぼ平 坦にすることができ液体をスム−ズに排出することができる。The breaking angle θ of the thin portion 4 is set to 50 ° as shown in FIG. 4 (a partially enlarged view of the circle indicated by arrow A in FIG. 1). As a result, the fracture surface (opening cross section) of the thin portion 4 can be made substantially flat and the liquid can be smoothly discharged.
【００１２】 図５は本考案の連通部材１１の概略図で、図６は図５のＣ矢視図、図７は図６ のＤ矢視図で、図８は図６のＡ−Ａ断面図である。連通部材１１は連通部材１と 比較して小径部１２の外周に翼部１７が形成されていること、大径部１３の液体 流路１８の径Ｄ４（２ｍｍから３ｍｍ）及び薄肉部１４付近の液体流出口１９の 径Ｄ３（１．９ｍｍから２．２ｍｍ）が小径に形成されていること、薄肉部１４ の破断角度θが図９（図５の矢印Ｂの円内の一部拡大図）に示すように６０°に 形成されている点が異なっており、他は連通部材１と同様である。FIG. 5 is a schematic view of the communicating member 11 of the present invention, FIG. 6 is a view taken in the direction of arrow C in FIG. 5, FIG. 7 is a view taken in the direction of arrow D in FIG. 6, and FIG. It is a figure. Compared to the communicating member 1, the communicating member 11 has a blade portion 17 formed on the outer periphery of the small diameter portion 12, the diameter D4 (2 mm to 3 mm) of the liquid flow path 18 of the large diameter portion 13 and the vicinity of the thin portion 14. The diameter D3 (1.9 mm to 2.2 mm) of the liquid outlet 19 is formed to be small, and the breaking angle θ of the thin portion 14 is shown in FIG. 9 (a partially enlarged view within the circle of arrow B in FIG. 5). As shown in FIG. 3, the difference is that it is formed at 60 °, and the other points are the same as those of the communication member 1.
【００１３】 連通部材１１は小径部１２の外周に翼部１７を形成しその前方側面の長径Ｌ側 に斜面１５を形成することにより液体の流通状態をより良くする。すなわち薄肉 部１４を破断して大径部１３の流体流路１８より液体流出口１９を経て小径部１ ２の外周に流出した液体は翼部１７、斜面１５を経て速かに液体移送チュ−ブ側 に排出させることができる。The communicating member 11 has a blade portion 17 formed on the outer periphery of the small diameter portion 12 and an inclined surface 15 formed on the front side surface of the blade portion 17 on the major axis L side to improve the liquid circulation state. That is, the liquid that has broken off the thin portion 14 and has flowed out of the fluid flow path 18 of the large diameter portion 13 to the outer periphery of the small diameter portion 12 via the liquid outlet 19 passes through the blade portion 17 and the inclined surface 15 and is quickly transferred to the liquid transfer tube. It can be discharged to the side.
【００１４】[0014]
以上説明したように本考案の連通ピ−スは、切断する方向に関係なく均一な 力で折ることができるので、例えば自動分離装置等を使用して機械的に折る場合 にも無理な力が加わることなくスム−ズに切断することができる。液体の流量 を充分に確保することができ液体の排出も速かに行うことができる。 As described above, since the communication piece of the present invention can be folded with a uniform force regardless of the cutting direction, even if it is mechanically folded using, for example, an automatic separating device, an unreasonable force is applied. It can be smoothly cut without joining. A sufficient flow rate of the liquid can be secured and the liquid can be discharged quickly.
