Is it permissible to accept and use a prize (an electric blender) given by a usurious bank, knowing that the husband did not open an account or deal with it?

It is not permissible for the husband to take possession of the prize offered by the usurious bank, because it was given to him in exchange for his dealings with the bank and his depositing the company's funds with it. He must, therefore, give its equivalent value to the poor.
