A type of a manufactured item that is used in the provision of healthcare without being substantially changed through that activity. The device may be a medical or non-medical device.

The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes.

Within the context of the FHIR RESTful interactions, the resource has an id except for cases like the create and conditional update. Otherwise, the use of the resouce id depends on the given use case.

The metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content might not always be associated with version changes to the resource.

An Extension

Идентификатор конкретной версии, который отображается в части URL, относящейся к версии. Это значение изменяется при создании, обновлении или удалении ресурса.

Сервер присваивает это значение и игнорирует то, что указывает клиент, за исключением случая, когда сервер устанавливает целостность версии при обновлении/удалении.

Когда ресурс менялся в последний раз - например, когда изменилась версия.

Этот элемент обычно опускается в экземплярах, отправляемых с помощью PUT или POST. Вместо этого он заполняется в экземпляре ответа и при получении информации с помощью GET. Это значение задается менеджером сервера / ресурсов; то, что предоставляет клиент, не имеет значения. Это эквивалентно последнему изменению HTTP и должно иметь такое же значение при взаимодействии read.

uri, который идентифицирует систему-источник ресурса. Он предоставляет минимальный объем информации о [Provenance] (provenance.html#), которую можно использовать для отслеживания или определения источника информации на ресурсе. Источник может идентифицировать другой сервер FHIR, документ, сообщение, базу данных и т.д.

Точное использование источника (и возможное подразумеваемое Provenance.entity.role и agent.role) остается на усмотрение разработчика. Допускается только один указанный источник; для получения дополнительной информации о происхождении следует использовать полный источник. Источник может соответствовать Provenance.entity.what[x] или Provenance.agent.who[x], хотя это может быть и более общая или абстрактная ссылка.

Этот элемент может использоваться для указания текущего главного источника ресурса, имеющего канонический URL-адрес, если ресурс больше не размещен по каноническому URL-адресу.

Список профилей (ссылок на StructureDefinition ресурсы), которым, как утверждается, соответствует этот ресурс. URL-адрес является ссылкой на StructureDefinition.url.

Сервер и/или другая инфраструктура политики должны определять, проверяются ли и/или обновляются ли эти утверждения с течением времени. Список URL-адресов профиля представляет собой набор.

Метки безопасности, применяемые к данному ресурсу. Эти метки связывают определенные ресурсы с общей политикой безопасности и инфраструктурой.

Метки безопасности могут быть обновлены без изменения указанной версии ресурса. Список меток безопасности представляет собой набор. Уникальность основана на системе/коде, а версия и отображение игнорируются.

Теги могут быть обновлены без изменения заявленной версии ресурса. Список тегов представляет собой набор. Уникальность основана на системе/коде, а версия и отображение игнорируются.

Коды, представляющие различные типы тегов, обычно связанные с рабочим процессом; например, "Требуется проверка доктором Джонсом".

A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.

Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of its narrative along with other profiles, value sets, etc.

The base language in which the resource is written.

Language is provided to support indexing and accessibility (typically, services such as text to speech use the language tag). The html language tag in the narrative applies to the narrative. The language tag on the resource may be used to specify the language of other presentations generated from the data in the resource. Not all the content has to be in the base language. The Resource.language should not be assumed to apply to the narrative automatically. If a language is specified, it should it also be specified on the div element in the html (see rules in HTML5 for information about the relationship between xml:lang and the html lang attribute).

Языковой тег IETF для человеческого языка

A human-readable narrative that contains a summary of the resource and can be used to represent the content of the resource to a human. The narrative need not encode all the structured data, but is required to contain sufficient detail to make it "clinically safe" for a human to just read the narrative. Resource definitions may define what content should be represented in the narrative to ensure clinical safety.

Contained resources do not have a narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded information is added later.

These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, nor can they have their own independent transaction scope. This is allowed to be a Parameters resource if and only if it is referenced by a resource that provides context/meaning.

This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again. Contained resources may have profiles and tags in their meta elements, but SHALL NOT have security labels.

An Extension

Unique instance identifiers assigned to a device by manufacturers other organizations or owners.

Certain attributes, like serial number and UDI Carrier (the HRF or AIDC barcode string) are not device instance identifiers as they are not consistently able to uniquely identify the instance of a device, thus are not appropriate to be used to value Device.identifier. The barcode string from a barcode present on a device label or package may identify the instance, include names given to the device in local usage, or may identify the type of device. If the identifier identifies the type of device, Device.type element should be used. The identifier is typically valued if the serialNumber or lotNumber is not valued and represents a different type of identifier. However, it is permissible to still include those identifiers in DeviceDefinition.identifier with the appropriate identifier.type.

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

Этот элемент относится только к общим категориям идентификаторов. Его не следует использовать для кодов, которые соответствуют 1..1 идентификатору.system. Некоторые идентификаторы могут быть разделены на несколько категорий из-за общего использования. Там, где система известна, тип не требуется, поскольку тип всегда является частью определения системы. Однако системам часто приходится обрабатывать идентификаторы, когда система неизвестна. Между типом и системой не существует соотношения 1:1, поскольку многие различные системы имеют один и тот же тип.

Establishes the namespace for the value - that is, an absolute URL that describes a set values that are unique.

Identifier.system is always case sensitive.

There are many sets of identifiers. To perform matching of two identifiers, we need to know what set we're dealing with. The system identifies a particular set of unique identifiers.

The portion of the identifier typically relevant to the user and which is unique within the context of the system.

If the value is a full URI, then the system SHALL be urn:ietf:rfc:3986. The value's primary purpose is computational mapping. As a result, it may be normalized for comparison purposes (e.g. removing non-significant whitespace, dashes, etc.) A value formatted for human display can be conveyed using the http://hl7.org/fhir/StructureDefinition/rendered-value). Identifier.value is to be treated as case sensitive unless knowledge of the Identifier.system allows the processer to be confident that non-case-sensitive processing is safe.

Период времени, в течение которого идентификатор является/был действителен для использования.

Organization that issued/manages the identifier.

The Identifier.assigner may omit the .reference element and only contain a .display element reflecting the name or other textual information about the assigning organization.

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

An Extension

A reference to a location at which the other resource is found. The reference may be a relative reference, in which case it is relative to the service base URL, or an absolute URL that resolves to the location where the resource is found. The reference may be version specific or not. If the reference is not to a FHIR RESTful server, then it should be assumed to be version specific. Internal fragment references (start with '#') refer to contained resources.

Using absolute URLs provides a stable scalable approach suitable for a cloud/web context, while using relative/logical references provides a flexible approach suitable for use when trading across closed eco-system boundaries. Absolute URLs do not need to point to a FHIR RESTful server, though this is the preferred approach. If the URL conforms to the structure "[type]/[id]" then it should be assumed that the reference is to a FHIR RESTful server.

The expected type of the target of the reference. If both Reference.type and Reference.reference are populated and Reference.reference is a FHIR URL, both SHALL be consistent.

The type is the Canonical URL of Resource Definition that is the type this reference refers to. References are URLs that are relative to http://hl7.org/fhir/StructureDefinition/ e.g. "Patient" is a reference to http://hl7.org/fhir/StructureDefinition/Patient. Absolute URLs are only allowed for logical models (and can only be used in references in logical models, not resources).

This element is used to indicate the type of the target of the reference. This may be used which ever of the other elements are populated (or not). In some cases, the type of the target may be determined by inspection of the reference (e.g. a known RESTful URL) or by resolving the target of the reference.

Ресурс (или, для логических моделей, URI логической модели).

An identifier for the target resource. This is used when there is no way to reference the other resource directly, either because the entity it represents is not available through a FHIR server, or because there is no way for the author of the resource to convert a known identifier to an actual location. There is no requirement that a Reference.identifier point to something that is actually exposed as a FHIR instance, but it SHALL point to a business concept that would be expected to be exposed as a FHIR instance, and that instance would need to be of a FHIR resource type allowed by the reference.

When an identifier is provided in place of a reference, any system processing the reference will only be able to resolve the identifier to a reference if it understands the business context in which the identifier is used. Sometimes this is global (e.g. a national identifier) but often it is not. For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy.

When both an identifier and a literal reference are provided, the literal reference is preferred. Applications processing the resource are allowed - but not required - to check that the identifier matches the literal reference

Applications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it.

Reference is intended to point to a structure that can potentially be expressed as a FHIR resource, though there is no need for it to exist as an actual FHIR resource instance - except in as much as an application wishes to actual find the target of the reference. The content referred to be the identifier must meet the logical constraints implied by any limitations on what resource types are permitted for the reference. For example, it would not be legitimate to send the identifier for a drug prescription if the type were Reference(Observation|DiagnosticReport). One of the use-cases for Reference.identifier is the situation where no FHIR representation exists (where the type is Reference (Any).

This element only allows for a single identifier. In the case where additional identifers are required, use the http://hl7.org/fhir/StructureDefinition/additionalIdentifier extension.

Plain text narrative that identifies the resource in addition to the resource reference.

This is generally not the same as the Resource.text of the referenced resource. The purpose is to identify what's being referenced, not to fully describe it.

Unique device identifier (UDI) assigned to device label or package. Note that the Device may include multiple udiCarriers as it either may include just the udiCarrier for the jurisdiction it is sold, or for multiple jurisdictions it could have been sold.

UDI may identify an unique instance of a device, or it may only identify the type of the device. See UDI mappings for a complete mapping of UDI parts to Device.

An identifier that supports traceability to the event during which material in this product from one or more biological entities was obtained or pooled.

Necessary to support mandatory requirements for traceability from donor/source to recipient and vice versa, while also satisfying donor anonymity requirements. The element is defined consistently across BiologicallyDerivedProduct, NutritionProduct, and Device. The identifier references an event that links to a single biological entity such as a blood donor, or to multiple biological entities (e.g. when the product is an embryo or a pooled platelet product). A single biologicalSourceEvent identifier may appear on multiple products of many types derived from a single donation event or source extraction. As an example, a single donation event may provide 2 kidneys and a liver for organ transplantation, 2 corneas for eye surgery, heart valves and arterial tissue for cardiovascular surgery, multiple skin grafts, tendons, multiple shaped bone grafts and a large number of bone putty/paste products; and each of them may be assigned to the same biological source event identifier.

A name of the manufacturer or entity legally responsible for the device.

The date and time when the device was manufactured.

The date and time beyond which this device is no longer valid or should not be used (if applicable).

Lot number assigned by the manufacturer.

The serial number assigned by the organization when the device was manufactured.

Alphanumeric Maximum 20. While a serial number is a type of identifier, in the context of devices for which a UDI is required, thus a serial number may be part of the production identifier, it is more informative to have the serial number as a dedicated attribute together with the other UDI production identifier. When the device is not subject to including the UDI (e.g., its presence and exchange is not mandated by local regulatory requirements or specific use case at hand), thus the concept of production identifiers is not relevant as a set, it remains helpful for consistency to still use Device.serialNumber rather than using Device.identifier with an appropriate type. Systems that do not realize an identifier is a serial number may place it in Device.identifier or if the identifier.system is known for the serial number, it may also be populated in the Device.identifier as a globally unique id_.

This represents the manufacturer's name of the device as provided by the device, from a UDI label, or by a person describing the Device. This typically would be used when a person provides the name(s) or when the device represents one of the names available from DeviceDefinition.
