Traditional radial artery or venous catheterization/cannulation is a standard for blood sampling and blood pressure monitoring for emergency or maintenance care, respectively. According to White, L., Halpin, A. et. al (2016), each attempt the procedure becomes more difficult because of hematoma formation and vasospasm which all can hinder blood flow to the arm and cause ischemia. “Repeated painful stimuli like blood draws during the neonatal period have been associated with several adverse outcomes ... altered corticospinal tract, dysregulation of the stress response system, and internalising behavioural problems” (Deindl, P., et al., 2017). Costs for venous cannulation according to Goff, D et al. (2013), can range from $45 to $125 depending if complications arise during the procedure. Accounting for arterial catheterization costs, as well, which are similar to venous cannulation costs, this doubles the cost for paediatric hospitals per annum to about $84,000. Our proposed medical device consists of a transilluminator, and restraint device. Two different LEDs will be used in the transilluminator component that outputs 576-578 nm and 650-658 nm which are mostly absorbed in oxyhaemoglobin and deoxyhaemoglobin carrying vessels, respectively. The restraint component will house the electronics used for the transilluminator, include ergonomic designs for user experience, and include straps for minimising movement from involuntary movements.
