创建和管理 HL7v2 消息

本页面介绍了如何提取、创建、标记、列出、查看和删除 HL7v2 消息。 HL7v2 消息用于在系统之间传输临床数据。 HL7v2 消息可能包含有关观察结果的信息、要发送到药房的处方、金融交易等。

创建和提取 HL7v2 消息概览

messages.create 方法用于在 Cloud Healthcare API 中存储 HL7v2 消息。

messages.ingest 方法还可用于在 Cloud Healthcare API 中存储 HL7v2 消息。但是,如果成功,它还会生成一个包含 HL7v2 确认(ACK)消息的响应,如果出现错误,它会生成一个否定确认(NACK)消息,适用于回复期望这些确认的 HL7v2 接口系统。

使用 MLLP 适配器提取和创建消息

系统会使用最小底层协议 (MLLP) 在护理系统和 Cloud Healthcare API 之间传送 HL7v2 消息。如需了解详情,请参阅 MLLP 和 Google Cloud Platform MLLP 适配器。如需了解如何配置 MLLP 适配器来与 Cloud Healthcare API 进行安全通信,请参阅通过 TCP/IP 连接传输 HL7v2 消息

提取 HL7v2 消息

Cloud Healthcare API 从护理系统提取消息后,Cloud Healthcare API 会生成一个包含 hl7ack 字段的响应,该字段包含 base64 编码的 HL7v2 消息,具有以下特征:

  • 消息类型为 ACK
  • 发送方设施和接收方设施逆转,发送方应用与接收方应用逆转。
  • 消息的发送时间是当前时间,并生成新的控件 ID。
  • MSH-9.1 字段的值定义了消息类型。
  • MSA.1 字段的值定义了响应类型。AA 响应类型指示 Application Accept,表示消息已通过验证并成功提取。
  • MSA.2 值包含原始消息的控件 ID

以下示例展示了如何使用 projects.locations.datasets.hl7V2Stores.messages.ingest 方法提取 HL7v2 消息。

curl

要提取 HL7v2 消息,请发出 POST 请求并指定以下信息:

  • 父数据集的名称
  • HL7v2 存储区的名称
  • 一条消息
  • 访问令牌

以下示例显示了使用 curlPOST 请求以及名为 hl7v2-sample.json 的示例 JSON 文件。

curl -X POST \
     -H "Authorization: Bearer $(gcloud auth application-default print-access-token)" \
     -H "Content-Type: application/json; charset=utf-8" \
     --data-binary @hl7v2-sample.json \

创建 HL7v2 消息

以下示例展示了如何使用 projects.locations.datasets.hl7V2Stores.messages.create 方法创建 HL7v2 消息。

curl

要创建 HL7v2 消息,请发出 POST 请求并指定以下信息:

  • 父数据集的名称
  • HL7v2 存储区的名称
  • 一条消息。如果需要示例 HL7v2 消息来用于示例命令,则可以下载 hl7v2-sample.json JSON 文件。
  • 访问令牌

HL7v2 消息细分分隔符和编码

HL7v2 中的默认细分分隔符是回车符 (\r)。大多数文本编辑器都使用换行符 (\n) 作为细分分隔符。这会生成使用默认配置无法提取到 Cloud Healthcare API 中的 HL7v2 消息。要允许 HL7v2 存储区提取使用换行符作为细分分隔符的消息,请参阅设置细分终止符

要将文件中的换行符转换为回车符,请在 Linux shell 中运行以下命令:

sed -z 's/\n/\r/g' INPUT_FILENAME > OUTPUT_FILENAME

提取和创建方法要求 HL7v2 消息采用 base64 编码的字符串。要将字符串转换为 base64 编码,请在 Linux shell 中运行以下命令:

openssl base64 -A -in ./INPUT_FILENAME -out ./OUTPUT_FILENAME

设置细分终止符

在创建或提取数据时,HL7v2 消息格式要求分段使用回车符 \r 终止细分。您可以将 HL7v2 存储区配置为接受包含非标准终止符(如 \n)的 HL7v2 消息。

请考虑以下使用默认 \r 作为细分终止符的 HL7v2 消息。默认情况下,当您创建 HL7v2 存储区时,系统会接受此消息。

MSH|^~\\&|FROM_APP|FROM_FACILITY|TO_APP|TO_FACILITY|20150503223000||ADT^A01|20150503223000|P|2.5|\r

PV1||I|H73 RM1^1^^HIGHWAY 73 CLINIC||||5148^MARY QUINN|||||||||Y||||||||||||||||||||||||||||20150503223000|\r

以下消息与上一条消息相同,只不过它使用 \n 作为细分终止符:

MSH|^~\\&|FROM_APP|FROM_FACILITY|TO_APP|TO_FACILITY|20150503223000||ADT^A01|20150503223000|P|2.5|\n

PV1||I|H73 RM1^1^^HIGHWAY 73 CLINIC||||5148^MARY QUINN|||||||||Y||||||||||||||||||||||||||||20150503223000|\n

要存储包含非标准终止符的消息,请在 HL7v2 存储区中配置ParserConfig对象,并将 segmentTerminator 字段设置为 \n 的 base64 编码。

以下示例展示了在创建 HL7v2 存储区时,如何在 ParserConfig 中配置 segmentTerminator。如果已有 HL7v2 存储区,则可以对其进行修改以提供 ParserConfig 正文。设置细分终止符后,可以创建提取消息。

curl

要创建将细分终止符设置为 \n 的 HL7v2 存储区,请发出 POST 请求并指定以下信息:

  • 父数据集的名称
  • HL7v2 存储区的名称
  • segmentTerminator 设置为 Cg==parserConfig 对象(\n 的 base64 编码)
  • 访问令牌

以下示例展示了使用 curlPOST 请求。

curl -X POST \
    --data "{
      'parserConfig': {
        'segmentTerminator': 'Cg=='
      }
    }" \
    -H "Authorization: Bearer $(gcloud auth application-default print-access-token)" \
    -H "Content-Type: application/json; charset=utf-8" \
    "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/hl7V2Stores?hl7V2StoreId=HL7V2_STORE_ID"

如果请求成功,服务器将以 JSON 格式返回响应:

{
  "name": "projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/hl7V2Stores/HL7V2_STORE_ID",
  "parserConfig": {
    "segmentTerminator": "Cg=="
  }
}

PowerShell

要创建将细分终止符设置为 \n 的 HL7v2 存储区,请发出 POST 请求并指定以下信息:

  • 父数据集的名称
  • HL7v2 存储区的名称
  • segmentTerminator 设置为 Cg==parserConfig 对象(\n 的 base64 编码)
  • 访问令牌

以下示例展示了使用 Windows PowerShell 的 POST 请求。

$cred = gcloud auth application-default print-access-token
$headers = @{ Authorization = "Bearer $cred" }

Invoke-WebRequest `
  -Method Post `
  -Headers $headers `
  -ContentType: "application/json; charset=utf-8" `
  -Body "{
      'parserConfig': {
        'segmentTerminator': 'Cg=='
      }
  } `
  -Uri "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/hl7V2Stores?hl7V2StoreId=HL7V2_STORE_ID" | Select-Object -Expand Content

如果请求成功,服务器将以 JSON 格式返回响应:

{
  "name": "projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/hl7V2Stores/HL7V2_STORE_ID",
  "parserConfig": {
    "segmentTerminator": "Cg=="
  }
}

使用空细分标头

不带消息标头细分 (MSH) 的 HL7v2 消息具有空的细分标头。通常情况下,HL7v2 消息会包含 MSH,它定义了消息的来源、意图、目的和目标等元数据。MSH 允许您搜索和过滤消息。但是,您可以通过在 HL7v2 存储区中配置 ParserConfig 对象并将 allowNullHeader 字段设置为 true,来存储不包含 MSH 的消息。

以下示例消息包含患者标识 (PID) 细分,但不包含 MSH:

PID|1||21004053^^^^MRN||SULLY^BRIAN||19611209|M|||123 MAIN ST^^MOUNTAIN SPRINGS^CO^80439

以下示例展示了在创建 HL7v2 存储区时,如何在 ParserConfig 中配置 allowNullHeader。如果已有 HL7v2 存储区,则可以对其进行修改并提供 ParserConfig 正文。将 allowNullHeader 设置为 true 后,您可以创建或提取具包含 null 细分标头的消息。

curl

要创建 HL7v2 存储区并存储不包含 MSH 的消息,请发出 POST 请求并指定以下信息:

  • 父数据集的名称
  • HL7v2 存储区的名称
  • allowNullHeader 设置为 trueparserConfig 对象
  • 访问令牌

以下示例展示了使用 curlPOST 请求。

curl -X POST \
    --data "{
      'parserConfig': {
        'allowNullHeader': true
      }
    }" \
    -H "Authorization: Bearer $(gcloud auth application-default print-access-token)" \

    "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/hl7V2Stores?hl7V2StoreId=HL7V2_STORE_ID"

如果请求成功,服务器将以 JSON 格式返回响应:

{
  "name": "projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/hl7V2Stores/HL7V2_STORE_ID",
  "parserConfig": {
    "allowNullHeader": true
  }
}

PowerShell

要创建 HL7v2 存储区并存储不包含 MSH 的消息,请发出 POST 请求并指定以下信息:

  • 父数据集的名称
  • HL7v2 存储区的名称
  • allowNullHeader 设置为 trueparserConfig 对象
  • 访问令牌

以下示例展示了使用 Windows PowerShell 的 POST 请求。

$cred = gcloud auth application-default print-access-token
$headers = @{ Authorization = "Bearer $cred" }

        'nullTerminator': true
      }

  "parserConfig": {
    "allowNullHeader": true
  }
}

为 HL7v2 消息添加标签

您可以向消息中添加一个或多个键值标签。标签的一个用例是向消息添加状态标签,以便应用可以按状态查询消息。

以下示例展示了如何使用 projects.locations.datasets.hl7V2Stores.messages.patch 方法向 HL7v2 消息添加标签。

curl

要为 HL7v2 消息添加标签,请发出 PATCH 请求并指定以下信息:

  • 父数据集的名称
  • HL7v2 存储区的名称
  • 消息 ID
  • 要更新的标签数据
  • 更新掩码
  • 访问令牌

以下示例展示了使用 curlPATCH 请求。

curl -X PATCH \
    -H "Authorization: Bearer $(gcloud auth application-default print-access-token)" \
    -H "Content-Type: application/json; charset=utf-8" \
    --data "{
      'labels': {
        'KEY' : 'VALUE'
      }
    }" "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/hl7V2Stores/HL7V2_STORE_ID/messages/MESSAGE_ID?updateMask=labels"

如果请求成功,服务器将以 JSON 格式返回响应:

获取 HL7v2 消息内容

以下示例展示了如何使用 projects.locations.datasets.hl7V2Stores.messages.get 方法获取 HL7v2 消息的内容。要确定要获取的消息部分,请为 view 查询参数提供以下选项之一:

  • BASIC:仅包括 name 字段。
  • RAW_ONLY:包括除 parsedData 字段之外的所有消息字段。
  • PARSED_ONLY:包括除 data 字段之外的所有消息字段。
  • FULL:包括所有消息字段。这是默认的。

以下示例展示了如何使用 FULLRAW_ONLYPARSED_ONLY 视图获取 HL7v2 消息的内容。

使用 FULL 视图

您无需显式设置 FULL 视图,因为 FULL 是默认值。但是,在以下 curl 和 Windows PowerShell 示例中,FULL 视图已添加为查询参数以提高完整性。

curl

要使用 FULL 视图获取 HL7v2 消息的内容,请发出 GET 请求并指定以下信息:

  • 父数据集的名称
  • HL7v2 存储区的名称
  • 消息 ID
  • FULL 作为 view
  • 访问令牌

以下示例展示了使用 curlGET 请求。

curl -X GET \
     -H "Authorization: Bearer $(gcloud auth application-default print-access-token)" \
     "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/hl7V2Stores/HL7V2_STORE_ID/messages/MESSAGE_ID?view=FULL"

PowerShell

要使用 FULL 视图获取 HL7v2 消息的内容,请发出 GET 请求并指定以下信息:

  • 父数据集的名称
  • HL7v2 存储区的名称
  • 消息 ID
  • FULL 作为 view
  • 访问令牌

以下示例展示了使用 Windows PowerShell 的 GET 请求。

$cred = gcloud auth application-default print-access-token
$headers = @{ Authorization = "Bearer $cred" }

删除 HL7v2 消息

以下示例展示了如何使用 projects.locations.datasets.hl7V2Stores.messages.delete 方法删除 HL7v2 消息。

curl

要删除 HL7v2 消息,请发出 DELETE 请求并指定以下信息:

  • 父数据集的名称
  • HL7v2 存储区的名称
  • HL7v2 消息 ID
  • 访问令牌

以下示例显示了使用 curlDELETE 请求。

curl -X DELETE \
     -H "Authorization: Bearer $(gcloud auth application-default print-access-token)" \
     "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/hl7V2Stores/HL7V2_STORE_ID/messages/MESSAGE_ID"

如果请求成功,服务器将以 JSON 格式返回空白正文响应:

{}

PowerShell

要删除 HL7v2 消息,请发出 DELETE 请求并指定以下信息:

  • 父数据集的名称
  • HL7v2 存储区的名称
  • HL7v2 消息 ID
