Figure 2.2.2.3.1: OK and BACK buttons mounted into caseAs seen in Fig. 2.2.2.3.2, a two button construction is being used for this interface.The up and down functions from the joystick will facilitate navigation through thegraphic user interface as well as selection of values when inputting rates andvolumes to be infused. The OK button is the general select button serving toselect the highlighted portions of the graphic user interface as well as confirminputs once they are correct. The BACK button will step back one step withevery push. It will move incrementally back through the various menus until itreaches the main menu. By allowing the patient to move backwards throughthe menus a confused patient will be allowed to start over.When placing the buttons on the interface, layout will be important. If thebuttons are too cluttered than the user may mistakenly hit the wrong input.Separating the joystick from the confirmation and back buttons will provide twodistinct areas with very different functions. These isolated areas of function willreduce problems when inputting information to the interface for disabledpatients. An example of this layout is shown in Fig. 2.2.2.3.2 on the next page.Figure 2.2.2.3.2: Button and joystick layout with separate areas for information input2.2.2.4 Rhino 12 Volt 3.4Ah Sealed Lead Acid Battery (Code: SLA-3-12)31
Figure 2.2.2.4.1: Rechargeable Lead Acid 12V battery in [2]A lead acid battery will be used in powering the accessible infusion pump userinterface.Figure 2.2.2.4.1 displays the battery that will be used in connection toour interface circuit. Since the terminals of this battery are hooks, connection tothe circuit will require simple wiring. Considering the use of this battery within aninterface, which is connected to a continuous infusion pump; continuous useand ability to recharge is paramount (Figure 2.2.2.4.2-next page). A 12V leadacid battery (3.4 Ah) has the ability to recharge, and considering these batteriesare used in most infusion pumps, the battery will be very reliable. Since the LCDrequires 5 volts, the controller and driver at least 8 volts, and Blackfin 7 volts; a12V battery would be well enough to power all the electronic subunits.Nonetheless, the battery will be used as a backup power supply when the 120VAC outlet power is not connected, lasting for 4 hours of stand alone use.32
