Description
【考案の詳細な説明】 ［産業上の利用分野］ 本考案は、人工腎臓、血漿分離装置等の体液処理装置
の栓の改良に関するもので、特に内部に蒸留水、生理食
塩水等の無菌水を充填した体液処理装置を、高圧蒸気滅
菌、放射線滅菌した際に、液漏れの生じない体液処理装
置の栓に関するものである。[Detailed description of the invention] [Industrial application field] The present invention relates to an improvement of a plug of a body fluid treatment device such as an artificial kidney and a plasma separation device, and particularly to a sterilized water such as distilled water or physiological saline inside. The present invention relates to a plug of a body fluid treatment device that does not leak when a body fluid treatment device filled with is subjected to high-pressure steam sterilization and radiation sterilization.
［従来の技術及び従来技術の課題］ 第３図は、現在使用されている体液処理装置の栓11の
概略図を示す。栓11は、内壁面に、抜きテーパー上に形
成された突出部12が形成されており、該突出部12を被栓
体部分13の開口部に圧着してシールしていた。[Prior Art and Problems of the Related Art] FIG. 3 is a schematic view of a stopper 11 of a body fluid treatment apparatus currently used. The plug 11 has a projection 12 formed on the extraction taper on the inner wall surface, and the projection 12 is pressed against the opening of the plug body portion 13 to seal it.
しかしながらこのような栓の形状では、 該突出部12が抜きテーパー状に形成されているため栓
11のシールが多少緩むと隙間が生じやすく隙間の部分か
ら液漏れが生じやすかった。However, in such a plug shape, since the protruding portion 12 is formed in a tapered shape, the plug is
When the seal 11 was slightly loosened, a gap was easily formed, and liquid leakage was likely to occur from the gap.
被栓体部分13の開口部からウレタン等の固化剤を導入
して、中空糸等の体液処理部材を固定する場合、被栓体
部分13の内壁面に固化剤が部分的に残存するため、突出
部12を圧着しても突出部12と被栓体部分13の間に隙間が
生じ、この隙間の部分から液漏れが生じることがあっ
た。When a solidifying agent such as urethane is introduced from the opening of the plug body portion 13 to fix the body fluid treatment member such as a hollow fiber, the solidifying agent partially remains on the inner wall surface of the plug body portion 13, Even when the protruding portion 12 is pressed, a gap is formed between the protruding portion 12 and the plug body portion 13, and a liquid leak may occur from the gap.
体液処理装置を放射線（γ線）照射する際、耐放射線
性の材質からなる栓を使用しても部分的な架橋が生じる
ため、栓が硬化して被栓体部分13から取り外しにくくな
っていた。When irradiating the body fluid treatment device with radiation (γ-rays), even if a plug made of a radiation-resistant material is used, partial cross-linking occurs, so that the plug is hardened and is difficult to remove from the plug body 13. .
栓体を各種の規格寸法にも合致する様に兼用で使用す
る場合があるので、栓体内部の形状が異形となりシール
部が安定せず液漏れの生じる原因となっていた。In some cases, the plug is used for two or more purposes so as to conform to various standard dimensions, so that the shape of the inside of the plug becomes irregular and the sealing portion becomes unstable, which causes liquid leakage.
また、これらの栓の改良として本願出願人は、実願昭
63−121562号に記載した栓を提案したが、これらの栓は
大径部を構成する樹脂量が多くコスト高になるという問
題点があった。In addition, as an improvement of these stoppers, the present applicant has
The plugs described in JP-A-63-121562 have been proposed, but these plugs have a problem that the amount of resin constituting the large diameter portion is large and the cost is high.
そこで以上の課題を解決するために本考案者は鋭意検
討を重ねた結果次の考案に到達した。In order to solve the above problems, the present inventors have made intensive studies and arrived at the following invention.
［課題を解決するための手段］ 第１図は、本考案の体液処理装置の栓１（以下『栓

径部２と封止部３から構成されている。[Means for Solving the Problems] FIG. 1 is a schematic view of a plug 1 (hereinafter abbreviated as “plug 1”) of the body fluid treatment device of the present invention. The stopper 1 is made of a thermoplastic elastomer resin such as a styrene-based elastomer, a polyolefin-based elastomer, a polyester-based elastomer, a polyurethane-based elastomer, or a synthetic rubber, and includes a large-diameter portion 2 and a sealing portion 3.
大径部２には、体液処理装置の被栓体部を外周から密
に圧着して密封できる鍔部４が形成されている。The large-diameter portion 2 is formed with a flange portion 4 that can tightly seal the plugged body portion of the bodily fluid treatment device from the outer periphery by pressing.
封止部３は、断続的にテーパー状のリブ６が複数形成
されており、これにより体液処理装置の被栓体部の内部
に圧入嵌合したときに、液密性を維持することができ
る。また先端部５は曲面に形成されており、自動組み立
て機で、栓１を被栓体部を挿入するときにスムーズに挿
入することができる。The sealing part 3 is formed with a plurality of tapered ribs 6 intermittently, so that the liquid tightness can be maintained when the sealing part 3 is press-fitted into the plug body of the body fluid treatment device. . Further, the distal end portion 5 is formed in a curved surface, so that the plug 1 can be smoothly inserted by the automatic assembling machine when inserting the plug body.
また第２図に示すように、栓1aは封止部３の内部に溝
７を形成することにより、体液処理装置にかかる内圧が
吸収され、外方向に封止部３が押し広げられるので、被
栓体部との密着性がさらに向上する。Also, as shown in FIG. 2, the stopper 1a forms the groove 7 inside the sealing portion 3 so that the internal pressure applied to the body fluid treatment device is absorbed and the sealing portion 3 is pushed outward, so that Adhesion with the plug body part is further improved.
［考案の効果］ 以上説明したように本考案の栓１は、栓の取り外しや
すさも良好で、滅菌工程において液漏れの発生が皆無で
被栓体部分との密着性をそこなうことなくがなく、大径
部２を構成する樹脂量も相対的に少なくすることができ
るので、コスト的メリットも大きい。[Effects of the Invention] As described above, the stopper 1 of the present invention has a good ease of removing the stopper, has no liquid leakage in the sterilization process, and does not impair the adhesion with the plug body. Since the amount of resin constituting the large diameter portion 2 can be relatively reduced, the cost advantage is great.
