Renesas: blood pressure monitoring evaluation kit for immediate evaluation

Renesas Electronics announced an expansion of its healthcare solution lineup with the launch of a new blood pressure monitoring evaluation kit. The new blood pressure monitoring evaluation kit comprises hardware and software elements needed to jump start blood pressure measurement design. The kit includes a pressure sensor, arm cuff, pump, electronically controlled valve, LCD panel, and a reference board that incorporates an RL78 Microcontroller based ASSP that includes analog functions required for blood pressure measurement. Reference software and GUI development tool are also part of the new evaluation kit. Using the new evaluation kit, system manufacturers can immediately begin their system evaluations and significantly reduce their development time.

Renesas has developed the new blood pressure monitoring evaluation kit to alleviate the development pain points, providing functions close to those used in actual blood pressure monitors thus accelerating blood pressure measurement system development.

The new blood pressure monitoring evaluation kit comprises hardware and software elements needed to jump start blood pressure measurement design, including:

  • A full range of hardware components, including a pressure sensor, arm cuff, pump, electronically controlled valve, LCD panel, and a reference board that incorporates the newly-developed RL78/H1D ASSP with the analog functions required for blood pressure measurement.
  • Reference software that provides the algorithms required for blood pressure measurement and that can be easily modified, as well as access to smartphone applications, and a GUI tool.
  • A Bluetooth Low Energy (BLE) module, which enables the measured data to be transmitted to a smartphone under the Continua standard blood pressure monitoring (BPM) profile is also provided in the new evaluation kit.  
  • The pressure sensor, pump, electronically controlled valve components, and pulse width modulation control can be set from the GUI tool. If the system structure is the same, the GUI tool can also be used for system evaluation of the actual application the system manufacturer is developing.
  • The IIR digital filter calculations required for extracting the pulse waveform from the cuff pressure output waveform during blood pressure measurement can also be simulated using the GUI tool. The digital filter constants calculated based on this simulation can be written from the GUI tool to the RL78/H1D firmware and verified in the actual application being developed. This significantly reduces the number of steps in the development process.
  • RL78/H1D ASSP with optimized analog functions for healthcare applications

Samples of the RL78/H1D ASSP are available now. Pricing varies depending on the memory capacity, package and number of pins.
