Wall-mounted light for Duke hospital
Design challenge: Nurses inspect and administer medication through patient's IV at night. Nurses want to avoid turning on overhead lights in the room while checking the IV site, since patients need their sleep to heal and the lights might wake them up. Nurses can't wear headlamps while wearing face shields and masks, and have to hold a flashlight under their arm or in one hand to light up the IV sight. This limits their range of motion, and ability to effectively administer medication through an IV.
Design Objectives:
- must be directionally adjustable
- light must be bright, white, and focusable
- must weigh less than 15 pounds
- must have low level of mechanical complexity
- light must last longer than 5 hours
- must cost less than $25
​
​
Design Constraints:
- must be able to be sanitized to meet hospital hygenic standards
- no colored light that may impact visual inspection of IV site
-device attachment can't interfere or harm the nurse, patient, or IV site
​
​
Taking into consideration the objectives and contraints, my team of four designed and fabricated a working prototype for a wall mounted arm.
​
Design Features:
- Apparatus is attached to the wall, above the patient's bed
- Accordian arm allows extension and retraction towards the wall
- Gooseneck with attached flashlight allows high flexibility of light's position
- Flashlight further adjusts to change beam focus
- Flashlight is wired to plug into a power outlet
