Premature baby simulator

The activities performed in the development of the premature neonatal simulator are research and design cycles to create a basic hard- and software architecture and to design and implement a simulator that enables training for assessment of vital signs ([Peters et al., 2010]). Different prototyping platforms are evaluated ([Peters et al., 2008]) and argumented choices are made for these implementation platforms. Realization of the envisioned simulator will be done in iterative steps. The resulting knowledge and expertise is used to create a prototype able to simulate several important vital signs.

Although the focus of the work is more on technology, the demands of each functionality implemented -and therefore the basis of the simulator- are based on real-life requirements:

  • Realistic display of clinical signs of a premature. The requirements are derived from the experience of medical staff in handling premature neonates. This also involves taking perception and human action possibilities into account.
  • Interactivity: responses generated using physiological models. The requirements are derived from the way the human organism works for real babies. Note that not only a healthy baby is to be simulated, but also the extremely unhealthy states of a baby that could occur immediately after birth.

The research question addressed in the design are:

  • Can we design a baby-manikin that simulates the specific features of a premature infant?
  • More specifically, can we design those elements of the baby-manikin that enable to assess a baby's vital signs?
  • Can we incorporate physiological models in such a way that the baby manikin responds adequately to treatments?
  • Can we fruitfully deploy contemporary developments such as miniaturization of embedded processors and 3D-printing?

At present we have preliminary prototypes that allow simulation of heart and lung sounds, skin colorization, muscle tension and arm movement. The prototype parts are built at the actual size of a preterm baby and construction parts (the inside mechanics as well as the actual baby-shell) are mainly created using a 3d printer. These prototypes incorporate specifically designed mechanic elements as well as the electronics to simulate the basic vital signs.
