摘要

Device for identifying the blood group characterized essentially by the fact of being constituted by two differentiated pieces, one of which is a laminar plate made of opaque plastic thermoformed material, in whose main face the signs corresponding to the blood group stand out, while the other the piece corresponds to the self-fixing means integrated by a strip of self-adhesive material of the same size as the plastic plate, and by a small magnet located between said plate and the self-adhesive strip.
