An extended quark mass density- and temperature- dependent model which includes the couplings between quarks and the sigma-mesons, omega-mesons is suggested. The MIT bag boundary constrain has been given up and the interactions between quarks and mesons are extended to the whole free space. We show that the present model is successful to describe both the saturation properties and the deconfinement phase transition of nuclear matter. When the effective nucleon masses vanish and the bag radius tends to infinite, the quark deconfinement takes place. The corresponding QGP phase diagram is addressed.
