Figure 2.1.3.3: RS-232 to Bluetooth with battery pack on left and without on right fromneteon.netThe infusion pump which was leant to the design team for this project comeswith an RS-232 serial port. Many infusion pumps on the market are similarlyequipped. Bluetooth can be applied to these devices easily by way of a serialto Bluetooth adapter, as seen in Figure 2.1.3.3. This adapter is powered by 5VDC which can be supplied through the RS-232 port. If the infusion pump doesnot supply power through the port, a battery pack can also be added, as seenin Figure 2.1.3.3. On the interface side, either USB or RS-232 can be used toestablish a Bluetooth connection.A few areas must still be addressed in the evaluation of Bluetooth as a viableoption. First, the protocol system output by the pump must be supported.Secondly, there are a few security concerns with Bluetooth. The concerns aremainly rooted in people leaving Bluetooth enabled devices in ‘visible’ mode.The possibility of virus being transmitted this way has been raised. The threatseems low, as the targets are cell phones which run a different operating systemthat the interface will, however the device should be kept in ‘hidden’ mode ifpossible.The Blackfin Processor was included to allow our LabVIEW® program (Fig.2.1.3.4) (which is available in our design lab) to operate our infusion pump. AnADSP-BF537 Blackfin Processor will be used to integrate majority of our subunitswithin our medical infusion pump user-interface. The processor will be with an“EZ-KIT Lite®” (Fig. 2.1.3.4) from National Instrument.23

Our team incorporated ABS casing to help allow easypackaging for our user-interface from Hammond Manufacturing ElectronicsGroup. An example of this casing is found below in Fig. 2.1.3.6.24
