HAPI：Hl7 解析器不分离 Hl7 消息的段

Question

我正在使用 HAPIAPI 开始学习 Hl7。我有一条 Hl7 测试消息（从真实案例中提取），我想读取各个段的字段（MSH、PID、PV1 等）问题在于Parser 没有将消息分段，而是将所有消息放在MSH 段中。我尝试了 PipeParser 和 GenericParser。该消息是 ORU_R01 消息，版本 2.3.1（我使用调试和 getVersion() 方法获取这些信息）

这里是测试class

    import java.io.IOException;

import ca.uhn.hl7v2.DefaultHapiContext;
import ca.uhn.hl7v2.HL7Exception;

import ca.uhn.hl7v2.model.v231.segment.MSH;
import ca.uhn.hl7v2.model.v231.segment.PID;
import ca.uhn.hl7v2.parser.Parser;

public class Hl7EncodeTester 
{
    public static void main (String[] args) throws HL7Exception, IOException
    {
        String msg = "MSH|^~\&|REPO|BCS|THE|Theorema|201412170140||ORU^R01|20140012620415|P|2.3.1||||||||PID|||711697^^^^PI^PRIAMO~RSSMHL69B15B081W^^^^NN||ROSSINI^MICHELE||19690215|F|||VIA^POMPEI^6^ASSO^CO^22063||031700239|||M||RSSMHL69B15B081W|300CP102||||ASSO|||100|||||PV1|||265^INRCA Ospedale^^959^^^0310^^||||||||||||||||||||||||||||||||||||||||||||||||||OBR|1||2014047190|69^RADIOLOGIA||||201412162247||||||||||||0310692014047190||201412162247|||||||||||||||OBX|1|FT|20140001988995||REFERTO FORMATO P7M BASE64 ||||||F|||20141216||CFmedicorefertante^CognomeMedicoRefertante^NomeMedicoRefertante||||TXA|1||multipart|||20141216|||||CFmedicorefertante^^^^^^^^^^^^COMPILATORE||||2014047190||AU|||||||NTE|1|O||";
        HapiContext context = new DefaultHapiContext();
//      Parser p = context.getPipeParser();
        Parser p = context.getGenericParser();
        Message adt = p.parse(msg);
        ORU_R01 oruMsg = (ORU_R01) adt;
        System.out.println("ORU_RO1 message = " + oruMsg.encode());
        MSH msh = oruMsg.getMSH();
        System.out.println("MSH segment = " + msh.encode());
        ORU_R01_PIDPD1NK1NTEPV1PV2ORCOBRNTEOBXNTECTI segment1 = 
                            oruMsg.getPIDPD1NK1NTEPV1PV2ORCOBRNTEOBXNTECTI();
        ORU_R01_PIDPD1NK1NTEPV1PV2 segment2= segment1.getPIDPD1NK1NTEPV1PV2();
        PID pid = segment2.getPID();
        System.out.println("Patient Name = " + pid.getPatientName(0).getXpn2_GivenName().getValue());
    }
}

这是控制台输出：

Patient Name = null

整个消息和我得到的MSH段是一样的，我不能把消息分割成段（应该是：MSH，PID，PV1，OBR，OBX，TXA和NTE）有人知道我的问题的解决方案吗？

Answer 1

您的邮件中没有段终止符。所以解析器找不到它。请注意，此终止符是二进制的，并且在标准

中是硬编码的

HL7 Messaging Standard Version 2.5 → Control → Message Framework → 2.5.4 Message delimiters

...The segment terminator is always a carriage return (in ASCII, a hex 0D). The other delimiters are defined in the MSH segment, with the field delimiter in the 4th character position...
