 TI release kits for developing ECG, digital stethoscopes and pulse oximeter

Based on its TMS320VC5505 digital signal processor (DSP), TI is offering new development kits for Medical electronics OEMs to develop ECG, digital stethoscopes and pulse oximeter products. The three medical development kits (MDKs) can be built by purchasing an analog front-end (AFE) module and a TMS320VC5505 DSP evaluation module (EVM).

The kits pack both hardware-board and the software design tools including schematic circuit diagrams, sample application source code, medical-specific algorithms and design support documents. The kits are designed to develop energy efficient medical electronic systems with sophisticated user functionality, such as real-time waveform display and menu options on an LCD screen and audio recording and playback.

Electrocardiogram MDK key features :
Front-end module with full set of analog circuitry, including the ADS1258 16-channel, 24-bit, low power analog-to-digital converter (ADC), for ECG applications, including defibrillator protection and 4KV isolation
12 lead ECG outputs using 10 electrode inputs, improving diagnostic interpretations
Includes a C5505 DSP EVM for extensive signal processing and medical algorithm implementation, including flexible/configurable filtering, 12 lead computation, QRS detection, leads off detection and real-time ECG waveform and heartbeat rate display on LCD and an external PC

Digital Stethoscope MDK key features :
Front-end module with all AFE circuitry, including the TLV320AIC3254 low power and low-voltage stereo audio codec, for digital stethoscope applications
Three-channel input option, two condenser and one contact microphones inputs with headphone output option
Three selectable modes for stethoscope operation, allowing the user to hear and focus on sounds of different frequency ranges in order to improve diagnostic accuracy:
Bell mode (20Hz to 220Hz)
Diaphragm mode (50Hz to 600Hz)
Extended range (20Hz to 2000Hz)
Includes a C5505 DSP EVM for extensive signal processing and volume control, audio storage/playback and real-time acoustic waveform and heartbeat rate display on an LCD and an external PC

Pulse Oximeter MDK key features :
Front-end module with all AFE circuitry, including the DAC7573 digital-to-analog converter and ADS8328 (Analog to Digital Converter), for pulse oximetry applications includes common signal conditioning path for red and infrared signals
Includes a C5505 DSP EVM that performs extensive signal processing, oxygen level percentage calculation ranging from 0 to 100 percent, pulse rate display, sensor off detection and real-time plethysmogram display on an LCD and an external Personal Computer.

TI warns, these kits are for feasibility evaluation by experts in laboratory/development environments only, and not for medical/diagnostic use on patients.
