Abstract
Addressing the lack of available systems for pressure ulcer prevention and treatment, the development of a monitoring and prevention system for deep seated pressure ulcers (DSPU) is described here. The measurement system comprising of a charge-based front-end amplifier, which feeds subsequent stages for adjusting gain, offset voltage and filtering, uses a unique mechanical impulse wave as input signal. This signal is passed through an analogue-to-digital converter for digitisation before being transferred to a computer via a USB port using a microcontroller for signal processing. The system response, tested with a Bose Electroforce and a laser vibrometer, showed a linear response over the measurement range necessary for DSPU prevention and detection and thus it was confirmed that the described development can provide an accurate measurement system for DSPU.
