The WA SDK leverages ActiveX 2.0, allowing Foundry Health IQVIA to communicate with supported devices through the ClinSpark Agent. The interface does not require ActiveX interaction by way of a browser plugin, but rather uses Microsoft’s COM API.

The Welch Allyn Connectivity SDK and supporting documentation were previously supplied directly by the vendor, Baxter (Welch Allyn). Baxter has recently communicated to IQVIA that they will no longer be hosting the SDK on their support website for download. Please contact your PM to gain access to the Connectivity SDK. IQVIA has been informed that Welch Allyn Connectivity SDK 2.3 and 3.0 are currently unsupported with Windows 11 and are in process of developing a new version. Once this newly supported version is supplied IQVIA will review and determine incorporating into a future release of Agent. |
Requirements
Welch Allyn Connectivity SDK 2.3 or 3.0 (as supported by Welch Allyn)
ClinSpark version 1.4.0 or greater
ClinSpark Agent version 1.1.0 or greater
...
User Requirements Specification (URS) is not included. Foundry Health IQVIA has reviewed the general requirements of the user community and used these to determine Functional and Non-Functional Requirements for this ClinSpark component.
ClinSpark Infrastructure specification (documented separately)
ClinSpark Architecture specification (documented separately)
ClinSpark Configuration Specification (documented separately)

The interface is reliant on the use of the Welch Allyn SDK. It is to be expected that Welch Allyn continue to develop the SDK and support additional devices that are brought to market. Foundry Health IQVIA will maintain the interface through the supported SDK updates and Welch Allyn devices, where applicable.
