January 2014 WG Meeting we proposed

“an architecture for distributed systems of medical devices in high acuity

environments” for standards adoption.

•definition and structuring of information that is communicated in a distributed system of point-of-care medical (PoC) medical devices and medical IT systems that need to exchange data or safely control networked PoC medical devices by defining a participant information model and service model. The definition of transport serialization is outside the scope of this standard.

-10207 Domain Information & Service Model for Service-Oriented Point-of-Care Medical Device Communication (BICEPS)

• service-oriented medical device architecture and communication protocol specification for distributed system of point-of-care medical (PoC) medical devices and medical IT systems that need to exchange data or safely control networked PoC medical devices by identifying the functional components, their communication relationships as well as the binding of the components and communication relationships to protocol specifications.

-20701 Service-Oriented Medical Device Exchange Architecture & Protocol Binding (SDC)

• communication protocol specification for a distributed system of point-of-care (PoC) medical devices and medical IT systems that need to exchange data or safely control networked PoC medical devices by defining a profile for Webservice specifications and defining additional Web service specifications as part of this standard

-20702 Medical Devices Communication Profile for Web Services (MDPWS)

The scope of this standard is …

Remote Control

Scenarios

Remote Control

Control

• Remote Settings

• How are the capabilities described to a remote client?

• How to change them?

• NIBP

• How do I start the measurement from a remote client?


Scenarios

Remote Control

Service Provider 1. Provide Capabilities & policies

2. Check if remote control request

can be executed safely

– Eligible service consumer

– Validity of request message

– Current device state allows execution

– Handle concurrent control commands

– Service Consumer subscribed to events

3. Execute control request

4. Inform service consumer about

progress

Service Consumer 1. Discover Service Provider

2. Check if policies can be fulfilled

3. Send remote control request

4. Wait for response

5. Handle events and failures


Scenarios

Remote Control

• SCO is part of a HydraMDS

• Contains OperationDescriptors that

describe the remote control

capabilities of the complete MDS


Scenarios

Remote Control

OperationDescriptor

• OperationTarget defines what is effected

by the operation

• Operations may have defined

Typed Operations

• SetRangeOperationDescriptor

• SetStringOperationDescriptor

• SetValueOperationDescriptor

• SetAlertStateOperationDescriptor

• SetContextOperationDescriptor

Complex Operations

• ActivateOperationDescriptor

• NonGenericOperationDescriptor


Scenarios

Remote Control


OperationState

• Can be used for every

OperationDescriptor as state

representation

• OperationMode to enable/disable

an operation

2 Specializations

Define what is currently allowed for

the operation.

• SetValueOperationState

• SetRangeOperationState

Scenarios

Remote Control

Assumption: Discovery already performed

Reference Implementation Update

What is OSCLib?


What is openSDC?

openSDC is a reference implementation of the extensible SDC protocol stack for

clinical workplace service-oriented medical device architectures

• BICEPS (Message & Service Model)

• MDPWS & DPWS (Transport)



openSDC

openSDC downloads since January 2014 WG Meeting

• Version beta05 was released end of February 2015

See http://sourceforge.net/projects/opensdc/



openSDC changes since last WG Meeting

Update in Q1/2015 (openSDC beta05)

• Optimized Discovery Mechanism

• Device context-based Discovery

• Descriptor exchange protocol optimization

• Incorporate change request from DKE & IEEE workgroups

Expect an update in Q2/2015 (openSDC beta06)

• Incorporate change request from DKE & IEEE workgroups

• Esp. 201505 BICEPS model will be included
