HL7 CDR组件如何表示/实现？

Question

I'm new to HL7 and I'm trying to figure out how to represent the PID segment - namely PID-5-10. PID-5-10 is the "CDR component" and it consists of 2 sub-components each made up of 2 values - Time and Degree of Precision . If I look at the standard separators defined in the MSH-2 it appears that there aren't enough separators to differentiate the Time and Degree of Precision values.

eg

PID|1|2|3|4|5-1^^^^^^^^^5-10-1.Time?5-10-1.Precision&5-10-2.Time?5-10-1.Precision^5.11

What's the standard separator I should use in place of the '?' in the above example? Any insight and assistance is much appreciated.

Answer 1

PID 5 is the patient name. Which is typically no more than

|last^first^mid^suffix^prefix|
