SEPARATION FILTER USABLE IN BLOOD SUPPLY SYSTEM Russian patent published in 2005 - IPC

FIELD: medical engineering.

SUBSTANCE: device is designed as disk having cylindrical casing, cover and filtering member placed between them, all provided with inlet and outlet canals and connected to each other in waterproof way. The casing, cover and filtering member are joined to each other with mechanical connection. To do it, acute-angled projection is produced on external surface. The internal surface has cylindrical shape transiting into flat ring-shaped sealing plate on casing bottom. Cavity is available in cover arranged along its perimeter formed by two coaxial cylinders of unequal diameter, ring-shaped projection being available on greater diameter cylinder surface and cylinder of lesser diameter smoothly transforms into flat ring-shaped sealing plate on casing bottom. The acute-angled projection thrusts against the ring-shaped projection of the greater cylinder in cover plane. External and internal casing cylindrical surface are coupled with the cylinders forming cover cavities. The filtering member is jammed between ring-shaped sealing plates of the casing and cover having ring-shaped projection and grooves. Filter design eliminates harmful factors from production process.

EFFECT: excluded expensive polymer materials and equipment; low electric power consumption; simplified assemblage process.
