(フィルタ材10)
図3はフィルタ材10の製造方法を説明する図である。まず、図3(a)に示すように、細長い板状のコア部材12にメッシュ状のスペーサ13を重ねることで、コア部材12で支持された被支持スペーサ10Aを形成する。メッシュ状のスペーサ13は、ポリオレフィン系高分子材料から製造される。スペーサ13としては、特にポリプロピレン(PP)、ポリエチレンテレフタラート(PET)からなる繊維を用いたメッシュを用いることが好ましい。メッシュのオープニングエリア(孔径)は、1.5mm~2.5mmであり、繊維の線径は、0.4mm~0.6mmのものを用いている。
実施形態では、袋状(筒状)のスペーサ13の内部にコア部材12を挿入することでコア部材12によってスペーサ13を支持する。ただし、これに限らず、平面状のスペーサ13でコア部材12の前面及び背面をくるんでもよい。さらに、スペーサ13をコア部材12の一面だけに重ねて配置してもよい。 (Filter material 10)
FIG. 3 is a diagram illustrating a method for manufacturing thefilter material 10. First, as shown in FIG. 3A, by superimposing the mesh-shaped spacer 13 on the elongated plate-shaped core member 12, the supported spacer 10A supported by the core member 12 is formed. The mesh-shaped spacer 13 is manufactured from a polyolefin-based polymer material. As the spacer 13, it is particularly preferable to use a mesh using fibers made of polypropylene (PP) or polyethylene terephthalate (PET). The opening area (hole diameter) of the mesh is 1.5 mm to 2.5 mm, and the wire diameter of the fiber is 0.4 mm to 0.6 mm.
In the embodiment, thespacer 13 is supported by the core member 12 by inserting the core member 12 into the bag-shaped (cylindrical) spacer 13. However, the present invention is not limited to this, and the front surface and the back surface of the core member 12 may be wrapped with a flat spacer 13. Further, the spacer 13 may be arranged so as to overlap only one surface of the core member 12.
図3はフィルタ材10の製造方法を説明する図である。まず、図3(a)に示すように、細長い板状のコア部材12にメッシュ状のスペーサ13を重ねることで、コア部材12で支持された被支持スペーサ10Aを形成する。メッシュ状のスペーサ13は、ポリオレフィン系高分子材料から製造される。スペーサ13としては、特にポリプロピレン(PP)、ポリエチレンテレフタラート(PET)からなる繊維を用いたメッシュを用いることが好ましい。メッシュのオープニングエリア(孔径)は、1.5mm~2.5mmであり、繊維の線径は、0.4mm~0.6mmのものを用いている。
実施形態では、袋状(筒状)のスペーサ13の内部にコア部材12を挿入することでコア部材12によってスペーサ13を支持する。ただし、これに限らず、平面状のスペーサ13でコア部材12の前面及び背面をくるんでもよい。さらに、スペーサ13をコア部材12の一面だけに重ねて配置してもよい。 (Filter material 10)
FIG. 3 is a diagram illustrating a method for manufacturing the
In the embodiment, the
次いで、図3(b)に示すように、被支持スペーサ10Aの外周に多孔質の中空糸14を巻き付ける。
このとき、中空糸14は、被支持スペーサ10Aの短手方向Sに延びるように巻き付けられる。すなわち、中空糸14は、被支持スペーサ10Aの一面側において、短手方向Sの一端から他端に向かって巻き付けられ、短手方向Sの他端で方向転換され、被支持スペーサ10Aの他面側において、短手方向の他端から一端に向かって巻き付けられ、短手方向の一端で方向転換される。これを繰り返して中空糸14を被支持スペーサ10Aの外周に巻き付ける。なお、このとき、隣接する中空糸14同士が重ならないように、且つ隙間なく巻き付けることが好ましい。
そして、この中空糸14の巻き付けを、被支持スペーサ10Aの長手方向Lの一方から他方側に向かって進行させて、被支持スペーサ10Aの略全体に渡って中空糸14を巻き付ける。 Next, as shown in FIG. 3B, the poroushollow fiber 14 is wound around the outer periphery of the supported spacer 10A.
At this time, thehollow fiber 14 is wound so as to extend in the lateral direction S of the supported spacer 10A. That is, the hollow fiber 14 is wound from one end in the lateral direction S toward the other end on one surface side of the supported spacer 10A, turned around at the other end in the lateral direction S, and is turned on the other surface of the supported spacer 10A. On the side, it is wound from the other end in the lateral direction toward one end and turned at one end in the lateral direction. This is repeated and the hollow fiber 14 is wound around the outer circumference of the supported spacer 10A. At this time, it is preferable to wind the adjacent hollow fibers 14 so that they do not overlap each other and without gaps.
Then, the winding of thehollow fiber 14 is advanced from one side of the longitudinal direction L of the supported spacer 10A toward the other side, and the hollow fiber 14 is wound over substantially the entire supported spacer 10A.
このとき、中空糸14は、被支持スペーサ10Aの短手方向Sに延びるように巻き付けられる。すなわち、中空糸14は、被支持スペーサ10Aの一面側において、短手方向Sの一端から他端に向かって巻き付けられ、短手方向Sの他端で方向転換され、被支持スペーサ10Aの他面側において、短手方向の他端から一端に向かって巻き付けられ、短手方向の一端で方向転換される。これを繰り返して中空糸14を被支持スペーサ10Aの外周に巻き付ける。なお、このとき、隣接する中空糸14同士が重ならないように、且つ隙間なく巻き付けることが好ましい。
そして、この中空糸14の巻き付けを、被支持スペーサ10Aの長手方向Lの一方から他方側に向かって進行させて、被支持スペーサ10Aの略全体に渡って中空糸14を巻き付ける。 Next, as shown in FIG. 3B, the porous
At this time, the
Then, the winding of the
次いで、図3(c)に示すように、中空糸14が巻き付けられた被支持スペーサ10Aの長手方向Lの一方から、コア部材12を抜き取ってスペーサ13の外周に中空糸14が巻き付けられた中空糸巻回体10Bを形成する。
Next, as shown in FIG. 3C, the core member 12 is removed from one of the longitudinal directions L of the supported spacer 10A around which the hollow fiber 14 is wound, and the hollow fiber 14 is wound around the outer periphery of the spacer 13. The bobbin winding body 10B is formed.
そして、図3(d)に示すように、中空糸巻回体10Bを長手方向Lの一方から他方に向かって巻いていき、ロール状に巻かれた円柱状のフィルタ材10を形成する。
Then, as shown in FIG. 3D, the hollow spool winding body 10B is wound from one side of the longitudinal direction L toward the other to form a cylindrical filter material 10 wound in a roll shape.
このように製造されたフィルタ材10は、スペーサ13の回りに中空糸14を重ならないように隙間なく巻き付けていくと、スペーサ13の表面に中空糸14が均一に配置される。そうすると、ロール状に巻いて円柱状にした場合においても、中空糸14が偏りなく配置されているので、フィルタリングのムラが生じない。
中空糸14はスペーサ13の回りに巻かれているので、コア部材12を外し、ロール状に巻いて円柱状にした場合においても、中空糸14の整列状態が保たれるので、フィルタリングのムラが生じない。
さらに、中空糸14は、スペーサ13の回りに巻き付けられているので、中空糸14同士の密着が防止される。そして、スペーサ13はメッシュ状であるのでフィルタリングの際の圧力損失も抑制できる。さらに、スペーサ13分の中空糸14の量を低減することができる。 In thefilter material 10 manufactured in this way, when the hollow fibers 14 are wound around the spacer 13 without gaps so as not to overlap with each other, the hollow fibers 14 are uniformly arranged on the surface of the spacer 13. Then, even when the hollow fibers 14 are rolled into a columnar shape, the hollow fibers 14 are arranged without bias, so that filtering unevenness does not occur.
Since thehollow fiber 14 is wound around the spacer 13, even when the core member 12 is removed and rolled into a columnar shape, the alignment of the hollow fibers 14 is maintained, so that filtering unevenness occurs. Does not occur.
Further, since thehollow fiber 14 is wound around the spacer 13, the hollow fibers 14 are prevented from coming into close contact with each other. Since the spacer 13 has a mesh shape, pressure loss during filtering can be suppressed. Further, the amount of the hollow fiber 14 for the spacer 13 can be reduced.
中空糸14はスペーサ13の回りに巻かれているので、コア部材12を外し、ロール状に巻いて円柱状にした場合においても、中空糸14の整列状態が保たれるので、フィルタリングのムラが生じない。
さらに、中空糸14は、スペーサ13の回りに巻き付けられているので、中空糸14同士の密着が防止される。そして、スペーサ13はメッシュ状であるのでフィルタリングの際の圧力損失も抑制できる。さらに、スペーサ13分の中空糸14の量を低減することができる。 In the

When the first circumferential groove 51 reaches the position of the insertion portion 44, the locking surface 49 moves from the position P2 in the figure to the position P1 due to the restoring force of the urging portion 46.
As a result, thelock surface 49 fits into the first circumferential groove 51, so that the device-side first attachment / detachment portion 40A and the tube-side second attachment / detachment portion 50A are prevented from coming off, and the cleaning filter device 1 and the upstream side tube are in a locked state. It is connected to 101U.

図1に戻り、プライミング時に血液循環回路100は、患者の体内を通らない循環回路として構築される。
まず、先端にビン針103が取り付けられたチューブ102を貯血槽3に接続し、ビン針103を生理用食塩水等のプライミング用の図示しない容器に接続する。血液ポンプ4が駆動されると、貯血槽3に生理用食塩水等のプライミング用の流体が流入される。貯血槽3に流入された流体は血液ポンプ4により吸引されて流路L1を通り、人工肺5を通って2方向の流路L2と流路L3とに分離される。一方の流路L2を通る流体は血液フィルタ装置6に入る。他方の流路L3を通る流体は、さらに2方向の流路L4と流路L5に分離される。流路L4の流体は血液フィルタ装置6に入り、流路L2の流体と合流して流路L6を流れて貯血槽3に戻る。流路L5の流体は、さらに2方向の流路L7と流路L8とに分離される。流路L7の流体は、洗浄フィルタ装置1を流れる。
ここで、洗浄フィルタ装置1において、流体とともに流れる血液循環回路100内の異物が除去される。異物が除去された流体は、流路L9及び流路L10に分離した後、合流して再び流路L7を流れ、流路L8の流体と合流して流路L5を流れ、貯血槽3に流入する。血液循環回路100内に存在していた空気も、流体とともに流れて貯血槽3に流入する。 (Priming)
Returning to FIG. 1, theblood circulation circuit 100 is constructed as a circulation circuit that does not pass through the patient's body during priming.
First, thetube 102 to which the bottle needle 103 is attached to the tip is connected to the blood storage tank 3, and the bottle needle 103 is connected to a container (not shown) for priming such as physiological saline. When the blood pump 4 is driven, a priming fluid such as a physiological saline solution flows into the blood storage tank 3. The fluid flowing into the blood storage tank 3 is sucked by the blood pump 4, passes through the flow path L1, passes through the artificial lung 5, and is separated into the flow path L2 and the flow path L3 in two directions. The fluid passing through one of the flow paths L2 enters the blood filter device 6. The fluid passing through the other flow path L3 is further separated into a flow path L4 and a flow path L5 in two directions. The fluid in the flow path L4 enters the blood filter device 6, merges with the fluid in the flow path L2, flows through the flow path L6, and returns to the blood storage tank 3. The fluid in the flow path L5 is further separated into a flow path L7 and a flow path L8 in two directions. The fluid in the flow path L7 flows through the cleaning filter device 1.
Here, in thecleaning filter device 1, foreign matter in the blood circulation circuit 100 flowing with the fluid is removed. The fluid from which the foreign matter has been removed separates into the flow path L9 and the flow path L10, then merges and flows through the flow path L7 again, merges with the fluid in the flow path L8, flows through the flow path L5, and flows into the blood storage tank 3. do.
