An internal joint cavity expander 10 includes femur-side magnets 12, tibia-side magnets 18, and magnetic shield members 24. Each femur-side magnet 12 is a magnet having a plate shape curved into an arc and fixed to a femur 52. Each tibia-side magnet 18 is a magnet having a length smaller than the length of the femur-side magnet 12 and having a plate shape curved into an arc concentric with the arc of the femur-side magnet 12. Each tibia-side magnet 18 is fixed to a tibia 54. The pole disposed on the convex surface of each femur-side magnet 12 is the same as the pole disposed on the concave surface of the corresponding tibia-side magnet 18. The convex surface of each femur-side magnet 12 is disposed so as to face the concave surface of the corresponding tibia-side magnet 18. Each magnetic shield member 24 is disposed so as to cover the entirety of a surface of the corresponding femur-side magnet 12 and the corresponding tibia-side magnet 18 facing the skin throughout the range in which the femur-side magnet 12 moves relative to the tibia-side magnet 18. Each magnetic shield member 24 prevents the magnetism of the corresponding magnets 12 and 18 from leaking outside without hindering the movement of the femur-side magnet 12 relative to the tibia-side magnet 18.

Provided is a safety cabinet which allows decontamination and disinfection operations in changeover procedures and the like to be carried out in a greatly reduced time. The safety cabinet is provided with a second operation chamber (20) that is provided in a first operation chamber (2) and into which clean air is supplied, a second suction opening (31) for sucking in air in the second operation chamber (20) and a portion of the air in the first operation chamber (2), and a second operation opening part (30) that is provided facing a first operation opening part (3) and communicates the second operation chamber (20) with the first operation chamber (2). Thus, airflow containment (air barrier) is doubled with respect to the outside of a safety cabinet (K1). Accordingly, in cases where decontamination and disinfection operations are carried out according to the changeover procedures, intensive decontamination and disinfection of the second operation chamber (20) is sufficient, and decontamination and disinfection of the first operation chamber (2) is hardly required. Therefore, decontamination and disinfection operations in the changeover procedures and the like can be carried out in a greatly reduced time.

A package 10 for cell-containing material includes an inner bag 12 and an outer bag 16. The periphery of the inner bag 12 except an opening 14 is sealed. The periphery of the outer bag 16 except an opening 24 is sealed. The outer bag 16 contains the inner bag 12 such that the opening 14 faces outward. A portion of the opening 24 outside the inner bag 12 is sealed and forms an outer bag sealed portion 28. A portion of the opening 24 that overlaps the inner bag 12 is sealed and forms an inter-bag sealed portion 18. A space surrounded by the outer surface of the inner bag 12 and the inner surface of the outer bag 16 is a sterilized closed space 20. The material of the inner bag 12 and the material of the outer bag 16 are selected such that the adhesive strength of heat sealing of the inner surfaces of the opening 14 of the inner bag 12 is greater than the adhesive strength of the inter-bag sealed portion 18 and the adhesive strength of the outer bag sealed portion 28.

A clean work device 10 includes a work area 30, a conveyor 25 in the work area, and a cleaning device 40. The work area 30 is disposed in a conveyance path P for cells C, and has an inlet 30a provided on the upstream side and an outlet 30b provided on the downstream side in a conveyance path P, with a downflow air curtain 50 provided at least at the inlet 30a and the outlet 30b. The conveyor 25 in the work area repeatedly performs an operation that moves a placement surface 25S having a culture vessel V thereon from the inlet 30a side into the work area 30, moves the placement surface 25S from the outlet 30b side to the outside of the work area 30, and, subsequently, moves back the placement surface 25S to the inlet 30a side. The cleaning device 40 cleans the placement surface 25S during the period from when the conveyor 25 in the work area moves the placement surface 25S to the outside of the work area 30 until the conveyor moves back the placement surface to the inlet 30a side of the work area 30.

An inner bag 20 of a cell culture package 10 is enclosed in an outer bag 50 such that a rubber stopper 24 is exposed to the outside. A closed space 56 surrounded by the outer surface of the inner bag 20 and the inner surface of the outer bag 50 is sterile. This allows the outer surface of the inner bag 20, which is used for containing cell-containing deformable materials, to be maintained in a sterile condition. Since the cell culture package 10 can be sterilized before a cell-containing deformable material is placed therein, the sterilization conditions can be relatively easily determined without considering the influence on the cell-containing deformable material. In addition, a holder 30 allows liquid to pass through the bottom surface and side surface of a recess and the bottom surface and the side surface of a cover. After a cell-containing deformable material is held in a holding space 30a, a liquid medium is added to the inner bag 20. During the culturing of the cell-containing deformable material, cells grow evenly over the entire cell-containing deformable material.

The convex surface of each femur-side magnet faces the concave surface of corresponding tibia-side magnet. Each magnetic shield-member covers the surface of corresponding femur-side magnet and tibia-side magnet facing the skin throughout range in which the femur-side magnet moves relative to the tibia-side magnet. Each magnetic shield-member prevents magnetism of corresponding magnets and from leaking outside without hindering the femur-side magnet movement relative to the tibia-side magnet.

A cell separation container 10 includes a collection chamber 20 and a tissue holding chamber 30 which are partitioned by a filter 40. The cell separation container 10 includes a first air pressure adjuster 60 configured to adjust the inflow and outflow of gas in the collection chamber 20 and a second air pressure adjuster 70 configured to adjust the inflow and outflow of gas in the tissue holding chamber 30. Thus, the inflow and outflow of the outside air and the gases in the collection chamber 20 and the tissue holding chamber 30 can be adjusted. In the cell separation container 10, switching between holding a treatment liquid in the tissue holding chamber 30 and ejecting a treatment liquid to the collection chamber 20 can be performed by adjusting the inflow and outflow of the outside air and the gas in the connection chamber 20.
