included in design two despite being in design one weren’t changed fromdesign one.2.1.3 Design 3Within the third alternative design, our team added four subunits to perfect ourdesign project: Toggle Switch/Joystick, Bluetooth <strong>Interface</strong>, Blackfin Processor,and Case/Packaging.Main reason for including the toggle switch/joystick was by replacing thescrolling arrow buttons with a single axis joystick, the patient will have easiermeans to choosing the correct menu or number from the LCD.Figure 2.1.3.1: Picture of J1 Low Profile "Switch Stick" Joystick from etisystems.com21
Figure 2.1.3.2: <strong>Engineering</strong> drawing of J1 Low Profile "Switch Stick" Joystick showingdimensions from etisystems.comBluetooth accessibility was included into our third design to allow wireless accessto the infusion pump for our patients. As the patient using this infusion pumpinterface may be confined to a bed or other low mobility position, the interfacemust be easily moved and handled to provide optimal accessibility. One wayto achieve this is to make the device wireless. Bluetooth technology makes thisa possibility. Bluetooth is a short-range, low-power radio frequency protocolused to set up a personal small-area wireless network. It allows for interface tobe simplified by reducing the number of cables required to connect devices.Bluetooth would allow this interface to interact with the infusion pump withoutbeing hardwired to it. This would in essence create a ‘remote control’ withwhich a patient could easily operate his or her infusion pump from a bed orother position where reaching the IV pole, and thus the infusion pump wouldprove difficult.22
