Chrome Compatible Telemedicine Stethoscope API in Beta

VIERA, FL – JULY 02, 2018 – RNK Products, Inc. (RNK) has created a Chrome compatible “application programmers interface” (API) for its PCP-SSP stethoscope signal processing software. This new API will enable Value Added Resellers (VARs) to easily integrate the FDA cleared stethoscope signal processing software into their own platform.

Key features of the PSP-SSP/API software include:

  1. Capability to use the audio channel of the video conferencing to pass the stethoscope signal.
  2. User selectable audio filters to enable clinicians to focus on lung sounds and heart sounds separately.
  3. Local loop back to enable a clinician with the patient to listen to the same sounds as the remote clinician.

Because it is built on Chrome and well matched to WebRTC video conferencing, PCP-SSP/API will work on any platform that hosts Chrome.

The PCP-SSP/API software works with the high performance PCP-USB stethoscope that dominates hospital/clinic telemedicine applications, including in the VA network. The PCP-USB is also the easiest to use telemedicine stethoscope on the market. It is a plug-n-play device that plugs into any USB port. It needs no batteries and there are no patient controls.

“The trend in telemedicine system development is to browser based technology using WebRTC for the video conferencing and Chrome for the browser,” says Rich Abbruscato, CEO of RNK. “PCP-SSP/API software and the PCP-USB stethoscope are ideal for those telemedicine systems serving all levels of acuity.”

To meet the demand for real-time stethoscopes in browser based telemedicine systems, RNK is pleased to move to the Beta stage for its Chrome compatible PCP-SSP/API software.

Press Release:  RNK Releases FDA Class II Cleared Telemedicine Stethoscope Software July 7, 2016 

RNK is pleased to announce the release of a simplified version of its FDA approved sSOIP telemedicine stethoscope software.  This new software version is called PCP-SSP and works with RNK’s flagship PCP-USB stethoscope.

Key PCP-SSP features:

  • Enables the stethoscope signal to be sent over the audio channel of a video conferencing connection.  No separate network connection needed.
  • Can automatically mute the room audio when stethoscope sounds are being sent.
  • Provides filtering options for the clinicians to focus on heart sounds and lung sounds separately.
  • Provides a local monitor capability so that the clinician with the patient can hear the same stethoscope sounds as the remote clinician.

Remote auscultation involves two software elements on the PC:  1) stethoscope signal processing and 2) network transport.  PCP-SSP lets the video conferencing equipment handle the network connectivity as an MDDS, while it handles the stethoscope signal processing as an FDA cleared medical device.  By performing the stethoscope signal processing functions and satisfying FDA requirements, PCP-USB relieves the video conferencing system of both technical and regulatory responsibilities.

All electronic stethoscopes are not approved for telemedicine.  For example, an electronic stethoscope with an analog connection to the Microphone port of the telemedicine system PC requires that the PC perform the analog-to-digital conversion (ADC) and digital encoding.  By doing that such a telemedicine system has inadvertently become subject to FDA regulations for a Class II medical device.

“We are very pleased to be able to respond to customer demand for a straight forward telemedicine stethoscope package that works with any Windows PC based video conferencing system and meets key clinical user needs while maintaining FDA compliance” says Rich Abbruscato, CEO of RNK.
