A combined filter for removing an aqueous fluid and entities, such as bacteria, existing in such aqueous fluid, from a nonaqueous fluid is described. The combined filter consists of a hydrophilic filter and a hydrophobic filter that are arranged in fluid communication and serially to be placed along the flow path of a fluid. The hydrophilic filter and the hydrophobic filter may touch one another or be located some distance from one another. Also, a structure may be inserted into the space between the hydrophilic filter and the hydrophobic filter that will maintain the space between the hydrophilic filter and the hydrophobic filter without significantly restricting the flow of fluid. And, in one embodiment, the combined filter may be composed simply of material having both hydrophilic and hydrophobic characteristics on the molecular level. Preferably, however, the filters and spacing structure are contained within an encasement having an inlet and an outlet. As any filter or spacer is located farther downstream with respect to the intended flow of fluid, the dimensions of that filter or spacer in the direction perpendicular to the intended flow of fluid increase to a sufficient extent that, as the stream of fluid expands perpendicularly to its intended direction of flow, the possibility of the fluid contacting any solid element other than a filter is decreased.

A filtering device incorporating nanoparticles that are known to be capable of destroying bacteria, fungi, viruses, or toxins. The nanoparticles are combined with a filter. The nanoparticles may be pellets adjacent to the filter, a powder of nanoparticles coating at least one side of a filter, or impregnated into a filter. Optionally, two or more filters are contained within an encasement having an inlet and an outlet. Preferably, at least one filter has an electrical charge that is the same as the electrical charge of at least one target particle. Also preferably, coating is accomplished by having a filter to be coated carry an electrical charge that is opposite to an electrical charge carried by the nanoparticles in the powder. Optionally, a filter can be either hydrophobic or hydrophilic.

A method and system for forming a hemostatic hydrocolloid for dispensing into a wound site includes a polymer of oxidized derivatized esterified cellulose in solid form comprising a chain of monomers, wherein, for a first plurality of the monomers in the chain: R is —OCH(COO)CHCH, R1 is —OCH(COO)CHCH, and R2 is —CHOCH(COO)CHCH; and wherein, for a second plurality of monomers in the chain: R is —OCH(COO)CHCH, R1 is —OCH(COO)CHCH, and R2 is —(COO)CHCHand a liquid mixed with the polymer to form a hemostatic gel for dispensing into a wound site.
