本発明は高温高圧滅菌時にすぐれた特性を有する血液浄
化器に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a blood purifier having excellent properties during high temperature and high pressure sterilization.
血液浄化器、例えば人工腎臓には従来がら各種のタイプ
が知られているが、士の中で近時、中空糸型人工腎臓が
主流となっている。Although various types of blood purifiers, such as artificial kidneys, have been known for a long time, hollow fiber type artificial kidneys have recently become mainstream among practitioners.
このような人工腎臓は透析を開始する前に洗滌、空気抜

である充＃Ａ１１Ｉｌが熱膨張・し、透析器の破損、充
填゛液漏れ等を起こすことになる。Such artificial kidneys require operations such as cleaning and air removal before starting dialysis, but in recent years, to make these tasks easier, the dialysis machine has been filled with liquid such as physiological saline in advance. A wet type is known. For this wet type sterilization, conventional formalin,
High-temperature steam sterilization (autoclave) is used instead of EoG sterilization, but if this sterilization method is used, the charged #A11Il filling the dialyzer will thermally expand, resulting in damage to the dialyzer and leakage of the filled fluid. I'll wake you up.

る。In the past, various countermeasures have been tried to prevent this.
For example, some measures have been taken, such as installing rubber plugs or other shock absorbing devices in the inflow and outflow channels of the dialyzer (although in any case, there are problems with actual dirt, such as the trouble of attaching and removing the rubber plugs).
本発明はこのような現状Ｋｌｉみて検討の結果提案され
たものでＴｏシ、血液の口過膜または透析膜を収納する
ケーシングを弾性樹脂製とするこ、とによシ、前記充填
液の熱膨張をその弾性作用で吸収しようとするものであ
る。The present invention was proposed as a result of studies in view of the current state of the art.The present invention includes the following features: The casing for housing the blood filtration membrane or the dialysis membrane is made of an elastic resin. It attempts to absorb expansion through its elastic action.

A hollow fiber bundle (2) is housed inside the casing (1), which has an overall flat shape, and both ends of the hollow fiber bundle (2) are covered with urethane resin (3).
) (3) is fixed.

が行なわれる。Such an artificial kidney S is filled with physiological saline or the like, and is sterilized at high temperature and high pressure with caps attached to the blood inlet/outlet (4) (5) and dialysate inlet/outlet (not shown).
しかして本発明では、前記ケーシング（１）を弾性樹脂

認されている。However, the present invention is characterized in that the casing (1) is made of elastic resin. Examples of such elastic resins include ethylene-vinyl acetate copolymer (EVA). EVA is a polymer obtained by copolymerizing ethylene and vinyl acetate, and it has been confirmed that it has excellent properties such as toughness, flexibility, stress crack resistance, and impact resistance depending on the molecular weight and vinyl acetate content. There is.
なお、本発明ではケーシング（１）の材質として、前記
したＥＶＡに限らず、他の弾性樹脂を使用してもよいこ
とは言うまでもない。It goes without saying that in the present invention, the material of the casing (1) is not limited to the above-mentioned EVA, but other elastic resins may be used.
ｔたケーシング（１）も上記した平偏層のみならず、円
筒渥その他の形状であってもよい。The shaped casing (1) is not limited to the above-described flat layered structure, but may also have a cylindrical shape or other shapes.

の効果のすぐれた発明である。According to the present invention as explained above, by making the casing especially made of elastic resin, even if the filling liquid heats and expands during high-temperature and high-pressure sterilization, the elasticity of the casing absorbs the pressure, as shown by the phantom line. Therefore, damage to the casing and membrane, leakage of the filling liquid, etc. can be prevented, and this is an excellent invention.
