Abstract
A filter and filtering apparatus for measuring the deformability of a blood cell passing through a flow passage formed as a space between a surface of a groove formed in a first substrate and a surface of a second substrate with which the groove is sealed. The filtering apparatus includes electrodes mounted at the inlets and outlets of the flow passages, or optical elements to enable cell deformity measurements.
Claims12
A blood filter comprising a first substrate having a plurality of small grooves formed on a surface thereon;
- a second substrate having a flat surface abutting on portions of the surface of the first substrate located between said grooves on said surface of said first substrate to form a plurality of blood flow passages constructed so as to filter blood between the first and second substrates, each of said blood flow passages having an inlet end and an outlet end;
- and inlet means for introducing blood into the inlet ends of said blood flow passages and outlet means for discharging blood received from the outlet ends of said blood flow passages.
A blood filter comprising a first substrate including a surface having a plurality of grooves formed thereon;
- a second substrate contacting the first substrate so as to form a plurality of blood flow passages within said grooves through which blood is permitted to flow;
- means for causing blood to flow through blood flow passages, and said second substrate including transparent means for observing the blood flowing in said flow passages from a surface of said second substrate.
