Laser-induced phase-separation polymerization of a porous acrylate polymer is used for in-situ fabrication of dialysis membranes inside glass microchannels. N-acetyl-D-glucosamine can obviously prolong the survival time of the experimental animal under the condition of cerebral ischemia and oxygen-deficiency at normal pressure, can decrease cerebral edema degree and other symptoms of the nerve behavior caused by cerebral ischemia and re-infusion. The interface may include generic routines commonly shared by the data storage mechanisms. There are means preventing blood leakage and personnel infecting. The belt is thus effectively cooled at a radial position within the driven or secondary pulleys, where due to a maximum power loss the generated heat is maximal.
