Abstract

PURPOSE:To improve an ultrafiltration amount(UFR) so as to make a desired UFR value settable by forming a fluid processor into module to fill its housing with fluid, thereafter filling the interior of a hollow thread film with sterilized pressure gas to apply sterilizing treatment. CONSTITUTION:Internal space of a hollow thread film is filled with sterilized air for about 5min at a pressure of about 0.2kg/cm<2> after the hollow thread film consisting of regenerated cellulose, is formed into module in a fluid processor to fill its housing with distilled water. Thereafter, a high pressure steamy sterilizing process is applied. A UFR can be confirmed and surely improved by the process thus applied, especially with increasing applied pressure and time of the sterilized gas. The UFR can be improved by maintaining the temperature of the charging fluid at a low value.

[Prior Art and Problems to be Solved by the Invention] A large amount of water is removed from dialysis patients suffering from renal disease at the same time as waste products such as urea and creatinine are removed. These moistures are removed by applying ultrafiltration pressure, and UFR is set as a value indicating the ultrafiltration ability of the body fluid treatment device.

UFR is adjusted by changing the thickness of the hollow fiber membrane loaded in the body fluid treatment device by several microns, but because the membrane thickness is extremely thin, the membrane thickness is not uniform, and UF
Adjustment of H was technically difficult. Attempts have been made to reduce the membrane thickness in order to improve UFR, but if the membrane thickness is made extremely thin, the membrane cannot sustain the ultrafiltration pressure, resulting in blood leakage during dialysis treatment, which can be fatal. This is not necessarily a good method as it may lead to an accident.
