FIELD: medicine.
SUBSTANCE: described are medical material and device for blood purification. Device is obtained by incorporating a medical material, which contains hydrophilic copolymer present on surface contacting blood, where 3/mcm2 or less of particulate protuberances of 50 nm or higher particle diameter are present on said blood-contacting surface, and relaxation time at -40 °C of water adsorbed to hydrophilic copolymer is 5.0×10-10 seconds to 2.5×10-8 s.
EFFECT: medical material and device have high antithrombotic properties and high safety.
