As a legal concept summarizing the legal norms in the field of health,"hygiene law"is difficult to carry the full value of health legal norms,and there is deviation from the right to health.The proposal of"health law"is the correction and reasonable replacement of"hygiene law",and also the co-hesion of health value in legal concept.The justification of"health law"in the normative sense depends on its normative core:it reflects the health consensus in the normative meaning,strives to realize the value pursuit of health justice,is supported by the right to health in the basic scope,and forms four secondary legal departments in the normative system:public health law,medical law,medical security law and health product law.
