Medical data sharing method

The invention provides a medical data sharing method. The method comprises the following steps: designing a lightweight index to obtain a patient index number; constructing an identification domain manager based on IHX and PIX to maintain the relationship between the patient index number and different medical institutions; acquiring medical data by using the lightweight index; splitting and/or combining the patient and the index number to correctly correspond to the patient and the index number; the collected medical data are stored; and calling the stored medical data by using the index number to realize sharing of the medical data. By designing the lightweight index, the stability of the index number can be ensured while the complexity of the operation logic is reduced, so that the concurrency performance is relatively good; by constructing the identification domain manager, standardization and normalization of data can be realized, and sharing of medical data is facilitated; by managing the relationship be
