Air Jammizz

Air Jammizz, automatic inflating pajamas to prevent bedsores for the elderly. 

Prototype 

Air pumped into a bladder in the shirt helps to rotate the person and alleviate pressure on the tailbone. Pressure sensors located around the tailbone detect critical pressure levels triggering the pump to turn on.

Air pumped into bladder in shirt

In the video above air is being pumped into a bladder into the shirt to help rotate the person to alleviate pressure on the tailbone. How this works is there are pressure sensors located around the tailbone that will trigger the pump to turn on once a certain pressure level has occurred for longer than 1 minute. 

Air pumped into bladder around ankle

Air pumped into a bladder around the ankle elevates the foot and relieves pressure on the heel.  Pressure sensors located around the heel detect critical pressure levels triggering the pump to turn on.

Description

    

      Some elderly people have a limited ability to change positions while they sleep or lie down. This lack of position change can lead to the development of bedsores that can develop on the heels, ankles, hips, and tailbone. Bedsores are caused by a prolonged period of pressure on the skin. For the worst case scenario bedsores can form within 30 minutes of someone lying in one position. Once a bedsore occurs, they are extremely difficult to treat and can often be deadly. The elderly can be at high risk of getting bedsores due to limited motion while lying down.

      The way to prevent bedsores is by changing position every two hours to alleviate the pressure. Currently, this is done by health care staff, who tend to have a difficult time adhering to this schedule, or by medical mattresses that are extremely expensive. Air Jammizz is a cheaper and portable solution. By sensing critical pressure levels in key locations along the body the pajamas are able to pump in air into bladders to alleviate the strain.

Research

Over the course of a couple of months, Brittany and Mengyuan went to assisted living homes to meet with senior's to discuss daily issues they face and different solutions to these problems. Brittany and Mengyuan also met with geriatric doctors to further understand seniors’ issues.

Testing Concept

A potentiometer is used to inflate a shirt. The potentiometer represents the pressure sensors, as the resistance increases on the potentiometer, more air is being pumped into the bladder and inflates the shirt. 

Potentiometer test

Shape test

Differently shaped bladders are tested to see how much weight they can lift.
