ABSTRACT:
A filter element that is particularly suitable for filtration of blood is made by compacting a mixture of fibers that is non-injurious to blood and one component of which has a lower softening temperature than the other component or components at a temperature sufficient to soften said fiber component and thereby bind the various fiber components together to form a stable and substantially uniform filter element.
