"SOMNUS: A SLEEP-MEASURING SHIRT BASED ON CHEST EXPANSION AND RESPIRATORY PATTERNS"
Presented by Thomas Lipoma, Massachusetts Institute of Technology
This paper presents a shirt embedded with simple capacitive sensors that accurately monitors the respiration of a sleeping person through chest expansion. It will also discuss a software package that, when coupled with this device, can determine sleep stages from the acquired data. Current sleep studies are the only medically accepted form of sleep health detection and diagnosis; due to the relatively high price of these studies, only persons with breathing-related disorders are referred to them. These studies depend on polysomnography, the use of various bodily signals for sleep detection; patients are often connected to over twenty sensors ranging from brain wave electrodes to blood oxygen trackers. The Somnus shirt is a comfortable, low-cost solution that could be used in the patientís regular sleep setting. Through some preliminary testing, our respiration-monitoring prototype was able to produce respiration data similar to that of sensors employed in current sleep labs while achieving a higher level of comfort for the user; also, the software package was able to analyze sleep with accuracy comparable to current sleep laboratory technicians.
"Innovative Renal Cooling Device for Use in Minimally Invasive Surgery"
Presented by Thomas Cervantes, Massachusetts Institute of Technology
Over 58,000 patients suffer from renal cell carcinoma annually in the US. Treatment for this cancer often requires surgical removal of the cancerous tissue in a partial nephrectomy procedure. In open renal surgery, the kidney is placed on ice to increase allowable ischemia time; however there is no widely accepted method for reducing kidney temperature during minimally invasive surgery. A novel device has been designed, prototyped, and evaluated to perform effective renal cooling during minimally invasive kidney surgery to reduce damage due to extended ischemia. The device is a fluid-containing bag with foldable cooling surfaces that wrap around the organ like a taco shell. It is deployed through a 12mm trocar, wrapped around the kidney and secured using bulldog clamps. The device then fills with an ice slurry and remains on the kidney for up to 20 minutes. The ice slurry is then removed from the device and the device is retracted from the body. Tests of the prototype show that the device successfully cools porcine kidneys from 37 C to 20 C in under 5 minutes.
