Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a fixing case used when an end portion of a fluid treatment device such as an artificial kidney dialyzer or a plasma separator is filled with a fixing agent.

[0002]

[Problems to be Solved by Prior Art and Invention]

 In the artificial kidney dialyzer, a hollow fiber membrane is loaded in the housing, and the end portion of the hollow fiber membrane is fixed by a fixing agent such as polyurethane. To fix the end of the hollow fiber membrane, attach a potting case of potting agent (“fixing case”) to the end of the housing, and apply a centrifugal force to the internal space formed in the potting case. However, it was carried out by filling a fixative and solidifying it.

However, the foaming styrol is usually used as the constituent material of the fixed case, which is inexpensive and easily available, and which can be easily processed according to the shape of the end of the fluid processing device. The styrol has a weak sealant strength of the fixative, and dust is easily generated at the time of release from the fixative, and dust adheres to the hollow fiber membrane, which is troublesome for cleaning work. It was Therefore, the inventor of the present invention has earnestly studied to solve the above problems, and has arrived at the next idea.

[0004]

[Means for Solving the Problems]

 The present invention is a fixing case used for filling an end portion of a fluid treatment device with a fixing agent, the fixing groove of the fluid treatment device, a space filled with the fixing agent, and a fixing agent communicating with the space. And a film cup is attached to the fixing groove to provide a fixing case.

[0005]

[Action]

 Since the film cup is placed between the fixing case and the fixing agent and is not in direct contact with the fixing case, the end portion of the fluid treatment device in which the fixing agent is filled into the housing and solidified is fixed to the fixing case. It can be removed more easily.

[0006]

【Example】

 FIG. 1 is a schematic view of a fixed case 1 of the present invention mounted on an end of a fluid treatment device 10 in which a hollow fiber membrane 12 is loaded in a housing 11. The fixing case 1 is provided with a fixing groove 2 of a fluid treatment device, a space 3 filled with a fixing agent such as polyurethane, and a fixing agent injection path 4 communicating with the space 3, and a film is formed in the fixing groove 2. Cup 5 is installed.

The film cup 5 is made of a fixing agent such as polypropylene or polyethylene and a material having a good mold release property, and is formed in conformity with the stepped shape of the end portion of the fluid treatment device 10 and the fixing groove 2. There is. That is, as shown in FIG. 2, a flange portion 6 is formed at the end portion, and a large diameter cylinder 7 and a small diameter cylinder 8 are projected on the flange portion 6.

When the end of the housing 11 loaded with the hollow fiber membrane 12 is filled with the fixative, the fixative is filled into the space 3 through the injection path 4 while applying a centrifugal force and solidified. After the fixing agent has solidified, the fixing case 1 is removed from the housing 11, the end of the hollow fiber membrane 12 is cut, and a port (not shown) is attached. Since the film cup 5 is arranged between the fixing case 1 and the fixing agent and is not in direct contact with the fixing case 1, the end portion of the fluid treatment device 10 in which the fixing agent is filled and solidified in the end portion of the housing 11 is It can be removed more easily than the fixed case 1.

[0009]

[Effect of the device]

 As described above, according to the present invention, the end portion of the fluid treatment device 10 can be easily removed without generating dust from the fixed case 1 and without damaging the fixed case 1. Since the fixed case 1 can be re-used, the manufacturing cost can be reduced.
