Description

本発明は、栓体、医療用具用液体ポートの封止構造及び該封止構造を持つ医療用具に関する。   The present invention relates to a plug, a sealing structure for a liquid port for a medical device, and a medical device having the sealing structure.

内部に水や水溶液等の液体が充填された医療用具、例えば、人工腎臓、血漿分離器、白血球除去器、血液成分吸着材等は、体液の循環や水、水溶液等の通液のための一個以上の液体ポートを有する。これらの液体ポートには、滅菌時や輸送時に、内部液体が漏出するのを防止する等の目的で栓体が被冠されている。   Medical devices filled with liquids such as water and aqueous solutions, such as artificial kidneys, plasma separators, leukocyte removers, blood component adsorbents, etc., are used to circulate body fluids and pass water, aqueous solutions, etc. It has the above liquid ports. These liquid ports are covered with plugs for the purpose of preventing leakage of internal liquid during sterilization or transportation.

例えば特許文献１（特開平７−２７５３５６号公報）に記載の栓体は、円形の保持部と、その下面中央部から凸設した外周に円形のリブを有すると共に底面に開設された凹陥部を有する装着部とを、一体成形している。これらの形状・構造により内圧が上昇したときに、前記凹陥部が外側に向けて押圧され、液体ポートの内周面にしっかりと圧着することにより、不用意に脱栓することを防いでいる。   For example, the stopper described in Patent Document 1 (Japanese Patent Application Laid-Open No. 7-275356) has a circular holding portion, a circular rib provided on the outer periphery protruding from the central portion of the lower surface, and a recessed portion opened on the bottom surface. The mounting part which has is integrally formed. When the internal pressure rises due to these shapes and structures, the concave portion is pressed outward and firmly pressed against the inner peripheral surface of the liquid port, thereby preventing inadvertent unplugging.

しかしながら液体ポートの大部分は外部に露出した状態となっており、特に打栓あるいは抜栓時において、手指の接触などによる汚染が発生する懸念がある。さらに、いずれも、密封機能と保栓機能とは共に摩擦係合によって維持されており、打栓時の摩擦抵抗が大きいため、栓体を打栓する作業は容易ではない。
またこのような栓体を持つ封止構造では、設計値よりも高い内圧が生じた場合に、栓抜けによる密封破壊が生じるのを完全に防止するのは困難であり、輸送中などに充填液体が漏出するような虞れがある。 However, most of the liquid ports are exposed to the outside, and there is a concern that contamination will occur due to finger contact, etc., particularly when the stopper is plugged or unplugged. Furthermore, in both cases, the sealing function and the plug retaining function are both maintained by frictional engagement, and the frictional resistance during plugging is large, so that the operation of plugging the plug is not easy.
In addition, in such a sealing structure having a plug, it is difficult to completely prevent a seal breakage due to plug removal when an internal pressure higher than the design value occurs. May leak out.

また特許文献２には、液体ポートの外周面に突起部、栓体の内側に溝部を形成し、ねじ込みによりできるようにした医療用具用液体ポートの封止構造が記載されているが、栓体をポートの上側部から締め付ける点、栓体をポートから容易に取り外す構造については、まだ改良の余地がある。
特許文献２の発明は、特許文献１の発明の課題（汚染の発生、栓抜け等）を解決した優れた発明であるが、ねじ込み式であるため、組み立て自動機に適用しにくい、栓体を外しにくい等の難点がある。 Patent Document 2 describes a sealing structure for a liquid port for a medical device in which a protrusion is formed on the outer peripheral surface of the liquid port and a groove is formed on the inner side of the plug, which can be screwed. There is still room for improvement in terms of tightening from the upper side of the port and the structure for easily removing the plug from the port.
The invention of Patent Document 2 is an excellent invention that solves the problems of the invention of Patent Document 1 (occurrence of contamination, unplugging, etc.), but it is a screw-in type, so it is difficult to apply it to an automatic assembly machine. There are difficulties such as difficult to remove.

本発明は、上記のような栓体を備えた医療用具用液体ポートの封止構造に生じている前記したような不都合を解消することを目的としており、装着（打栓）及び取り外し（抜栓）が容易であり、装着（打栓）及び取り外し（抜栓）などに液体ポートに直接接触する可能性を極力低減でき、さらに、滅菌時や輸送時などにおいて容器内圧が上昇したときに、栓抜け等により内部液体が漏出するのを完全に防止することのできる栓体、医療用具用液体ポートの封止構造並びに封止構造を持つ医療用具を提供することを目的とする。   An object of the present invention is to eliminate the inconveniences described above that occur in the sealing structure of a liquid port for a medical device provided with the plug as described above, and mounting (plugging) and removal (plugging). The possibility of direct contact with the liquid port during mounting (plugging) and removal (unplugging) can be reduced as much as possible, and when the container internal pressure rises during sterilization or transportation, etc. It is an object of the present invention to provide a plug that can completely prevent leakage of internal liquid, a medical device liquid port sealing structure, and a medical device having a sealing structure.

The pressing member 7 can be attached to the sealing member 4 as an integral molding or as a separate part. In practice, it is preferable to form the pressing member 7 larger than those illustrated in FIGS. 1 to 4 because the air venting efficiency is better.

栓体１をポート３０に装着する方法の一例について説明する。図２の状態（封止部材４の両側にハウジング２Ａ、２Ｂを配置）から図３のように、栓体１の密封部材４を、ポート３０の上部開口部３５に装着する。
図３のように、内側筒状密封体５はポート３０の上部開口部３５に嵌入され、外側筒状密封体６はポート３０の小径部３２の外周に嵌入される。
さらに図４（Ａ）のように、一方のハウジング２Ａを９０°下方に回動させ、挟持部１１を外側筒状密封体６、突起部１２をポート３０の環状溝部３３に当接する。さらに図４（Ｂ）のように、もう一方のハウジング２Ｂを９０°下方に回動させ、挟持部１１を外側筒状密封体６、突起部１２をポート３０の環状溝部３３に当接し、係合突起部１３と係合溝部１４を係合する。
ポート３０の上部開口部３５は、内側筒状密封体５により封をされ、外側筒状密封体６及び挟持部１１により外周から締め付けられるので、液密性を維持することができる。
押圧部材７を上から下方にポンピングすることにより、医療用具内に残留している空気を医療用具外部の押し出すことができる。 An example of a method for attaching the plug 1 to the port 30 will be described. The sealing member 4 of the plug 1 is attached to the upper opening 35 of the port 30 as shown in FIG. 3 from the state of FIG. 2 (the housings 2A and 2B are arranged on both sides of the sealing member 4).
As shown in FIG. 3, the inner cylindrical sealing body 5 is fitted into the upper opening 35 of the port 30, and the outer cylindrical sealing body 6 is fitted to the outer periphery of the small diameter portion 32 of the port 30.
Further, as shown in FIG. 4A, one housing 2 </ b> A is rotated downward by 90 °, and the sandwiching portion 11 is in contact with the outer cylindrical sealing body 6 and the protruding portion 12 is in contact with the annular groove portion 33 of the port 30. Further, as shown in FIG. 4B, the other housing 2B is rotated 90 ° downward, the clamping part 11 is brought into contact with the outer cylindrical sealing body 6 and the projection part 12 is brought into contact with the annular groove part 33 of the port 30. The mating protrusion 13 and the engagement groove 14 are engaged.
Since the upper opening 35 of the port 30 is sealed by the inner cylindrical sealing body 5 and is tightened from the outer periphery by the outer cylindrical sealing body 6 and the sandwiching portion 11, the liquid tightness can be maintained.

図５は、本発明の栓体の一例を示す概略図で、（Ａ）は（Ｃ）のＡ−Ｏ−Ａ´線断面図、（Ｂ）は上面図、（Ｃ）は底面図、図６と図７は、本発明の栓体のポートへの装着方法を示す概略図で、図６は装着（打栓）時、図７は取り外し（抜栓）時、それぞれ（Ａ）は縦断面図、図６（Ｂ）は図６（Ａ）のＣ−Ｃ´線断面図、図７（Ｂ）は図７（Ａ）のＢ−Ｂ´線断面図である。
栓体５１は図５に例示するように、筒状体５２の天板５８の底部に筒状密封体５５、５６を下方に突設し、天面に押圧部材５７を形成し、さらに筒状体５２の内壁面に突起部５３を形成している。筒状体５２の断面は略楕円に形成されている。
内側筒状密封体５５は、小径で下方に長く突設され、外側筒状密封体５６は、大径で下方に短く突設されている。内側筒状密封体５５の外周には小突起部５３Ａが形成され、小突起部５３Ａはポート３０の円筒壁３１内面と接して、耐リーク性を高める機能を有する。小突起部５３Ａは連続的に環状に形成しても良いし不連続に形成しても良い。
押圧部材５７は前記押圧部材７と同様に筒状体５２の天板５８に形成されている。押圧部材５７の形状・構造・作用効果等は前記押圧部材７と実質的に同様であるから詳細な説明は省略する。突起部５３はポート３０の環状溝部３３に係合できれば良く、連続して環状に形成しても良いし不連続に形成しても良い。
筒状体５２の突起部５３を形成した側の上部壁面と外側筒状密封体５６の間には、反対側（突起部５３を形成していない筒状体５２の上部壁面と外側筒状密封体５６の間）よりも大きな隙間５４を形成している。これにより、栓体５１をポート３０より外すとき変形しやすく、容易に取り外すことができる。 5A and 5B are schematic views showing an example of the plug of the present invention, where FIG. 5A is a cross-sectional view taken along the line A-O-A ′ of FIG. 5C, FIG. 5B is a top view, and FIG. 6 and 7 are schematic views showing a method of mounting the plug body of the present invention to the port. FIG. 6 is a mounting (plugging), FIG. 7 is a removal (unplugging), and (A) is a longitudinal sectional view. 6 (B) is a cross-sectional view taken along the line CC ′ of FIG. 6 (A), and FIG. 7 (B) is a cross-sectional view taken along the line BB ′ of FIG. 7 (A).
As illustrated in FIG. 5, the plug body 51 has cylindrical sealing bodies 55, 56 projecting downward from the bottom of the top plate 58 of the cylindrical body 52, a pressing member 57 is formed on the top surface, and the cylindrical body A protrusion 53 is formed on the inner wall surface of the body 52. The cross section of the cylindrical body 52 is formed in a substantially oval shape.
The inner cylindrical sealing body 55 has a small diameter and protrudes long downward, and the outer cylindrical sealing body 56 has a large diameter and protrudes short downward. A small protrusion 53A is formed on the outer periphery of the inner cylindrical sealing body 55, and the small protrusion 53A is in contact with the inner surface of the cylindrical wall 31 of the port 30 and has a function of improving leak resistance. The small protrusions 53A may be formed continuously in an annular shape or discontinuously.
The pressing member 57 is formed on the top plate 58 of the cylindrical body 52 like the pressing member 7. Since the shape, structure, operational effect and the like of the pressing member 57 are substantially the same as those of the pressing member 7, detailed description thereof is omitted. The protrusion 53 only needs to be able to engage with the annular groove 33 of the port 30 and may be formed continuously in an annular shape or discontinuously.
Between the upper wall surface of the cylindrical body 52 on the side where the projection 53 is formed and the outer cylindrical sealing body 56, the opposite side (the upper wall surface of the cylindrical body 52 on which the projection 53 is not formed and the outer cylindrical seal is formed. A larger gap 54 is formed between the bodies 56). Thereby, when removing the plug body 51 from the port 30, it is easy to deform | transform and it can remove easily.

栓体５１をポート３０に装着する方法の一例について説明する。
図６のように、栓体５１を、ポート３０の上部開口部３５に装着する。
図６のように、内側筒状密封体５５はポート３０の上部に嵌入され、外側筒状密封体５６はポート３０の小径部３２の外周に嵌入される。突起部５３はポート３０の環状溝部３３に当接される。小突起部５３Ａはポート３０の円筒壁３１内面に当接される。ポート３０の上部開口部３５は、内側筒状密封体５５により封をされ、外側筒状密封体６により外周から締め付けられるので、液密性を維持することができる。
栓体５１を、ポート３０に装着した状態では、ポート３０と筒状体５２の間に若干の隙間が存在するが、筒状体５２は略楕円形に形成されているので、突起部５３と反対側の筒状体５２とポート３０の隙間のほうが若干広くなっている。
栓体５１をポート３０から取り外す際には、図７のように、突起部５３と反対側の筒状体５２壁面を押すと、突起部５３がポート３０の環状溝部３３から離脱し、栓体５１を上に引き上げることにより、離脱させることができる。 An example of a method for attaching the plug 51 to the port 30 will be described.
As shown in FIG. 6, the plug body 51 is attached to the upper opening 35 of the port 30.
As shown in FIG. 6, the inner cylindrical sealing body 55 is fitted into the upper portion of the port 30, and the outer cylindrical sealing body 56 is fitted into the outer periphery of the small diameter portion 32 of the port 30. The protrusion 53 is brought into contact with the annular groove 33 of the port 30. The small protrusion 53 </ b> A is in contact with the inner surface of the cylindrical wall 31 of the port 30. Since the upper opening 35 of the port 30 is sealed by the inner cylindrical sealing body 55 and tightened from the outer periphery by the outer cylindrical sealing body 6, it is possible to maintain liquid tightness.
In the state where the plug body 51 is attached to the port 30, there is a slight gap between the port 30 and the cylindrical body 52. However, since the cylindrical body 52 is formed in a substantially elliptical shape, The gap between the opposite cylindrical body 52 and the port 30 is slightly wider.
When removing the plug 51 from the port 30, as shown in FIG. 7, when the wall surface of the cylindrical body 52 opposite to the protrusion 53 is pressed, the protrusion 53 is detached from the annular groove 33 of the port 30, By lifting 51 upward, it can be detached.
