Problems with Gurneys
Currently in hospitals, patients are
transported by gurneys from their beds to
exam rooms or other locations in the hospitals. A major problem is that patients are jarred as the gurney is wheeled through the hallways.
Injuries
Also, the patient must be transferred from the
bed to the gurney to the exam table, and
back again to return to his or her room. During the transfers nurses are strained by lifting the patient from one platform to another and patients can be injured.
Ergonomic Handling
At present there are several devices that offer

Superconductors
A superconductor is a material that,
when kept at a certain temperature,
can conduct electricity without suffering a loss of charge, even if the source of electricity is removed.
Currently the highest temperature
superconductors are made of mercury,
thallium, barium, calcium, copper and oxygen, and can perform at 138 degrees K (-135degreesC). Superconductors are currently used in maglev trains, SQUIDS (device used in brain research), and MRI machines. They have limited usage because they have to be kept in liquid nitrogen, are very brittle, and expensive. |
