Figures & data
Figure 1 Ambient (A) and environmental-chamber (B) temperature-measurement set up and sensor placement (C).
Note: Images show infrared camera on tripod, foam board containing six battery-operated pumps, six rechargeable pumps, and two sensors.
Figure 2 Ambient-temperature results.
Notes: Battery and rechargeable battery pump temperatures, insulin degradation temperature, and ambient air temperatures shown, measured over 180 minutes.
Figure 3 Enviromental-chamber temperature results.
Notes: Battery and rechargeable battery pump temperatures, insulin degradation temperature, and chamber temperatures are shown, measured over 180 minutes in a controlled (35°C) environment.
Figure 4 Infrared image of temperature increases in rechargeable pumps, with the layout of the devices in the top-left corner.
Note: Measurements were performed in the environmental-chamber which was maintained at a constant temperature (35°C, 95°F).
