摘要:
The present disclosure relates, according to some embodiments, to methods, devices, and systems for fluid delivery to a subject using pumps, for example, non-gassing, direct current (DC), electro-osmotic pumps. In some embodiments, delivery of an aqueous fluid may be achieved by contacting the aqueous liquid with an electro-osmotic pump comprising (i) a cathode (e.g., a cathode comprising porous carbon coated with a cerium oxide-comprising coating), (ii) an anode (e.g., an anode comprising porous carbon coated with a cerium oxide-comprising coating), and (iii) a ceramic membrane (e.g., a ceramic membrane formed by fusing uncoated silica spheres, phosphosilicic-acid-coated fused silica spheres, or borosilicic-acid-coated fused silica spheres, wherein the fused spheres are randomly packed between the cathode and the anode) and/or optionally applying (a) a constant potential difference or constant voltage between the anode and the cathode of from about 0.1 V to about 3 V between the anode and the cathode of from about 0.1 V to about 3 V such that the aqueous liquid is pumped or (b) constant current to cause a potential difference between the anode and the cathode of from about 0.1 V to about 3 V such that the aqueous liquid is pumped.La présente invention concerne, selon certains modes de réalisation, des procédés, des dispositifs et des systèmes pour la distribution de fluides à un sujet en utilisant des pompes, par exemple, des pompes sans dégagement gazeux, à courant continu (DC), électro-osmotiques. Dans certains modes de realization, la distribution dun fluide aqueux peut être obtenue en mettant en contact du liquide aqueux avec une pompe électro-osmotique comprenant (i) une cathode (par exemple, une cathode comprenant du carbone poreux enduit dun revêtement comprenant de loxyde de cérium), (ii) une anode (par exemple, une anode comprenant du carbone poreux enduit dun revêtement comprenant de loxyde de cérium), et (iii) une membrane céramique (par exemple, une mem
