The focus of this project was the development of an ICU/Rehabilitation adjustable bed for the hospital and home environment. The project was initiated with the desire to develop an innovative, effective and inexpensive mechanism that would require an electrical supply. The design was performed systematically using various methods, procedures, techniques and materials to aid the process. One of the method used is carpentry, which was used to make the bed framework and the adjustable floor, which is 3 feet wide and 6 feet long and 28 inch (backrest), 1 feet (buttocks section), 14 inch (thigh section) and 19 inch (legrest section). Welding was used to make the arm, strut, crossbar and pivot and also screwing belts were used to hold the different parts together. The materials used for this project are: an electrical linear actuator, made from locally sourced materials (jack, steel pipes and 12 volt DC motor), wood, screws, bolts and nuts, foam, mattress, remote control, 24 volt adapter, nails and hinges. A total cost of 75,000 naira was used for the overall design and construction process. The final design uses an electrical linear actuator made from locally sourced materials to move the top adjustable sections. A six bar linkage mechanism delivers a combined back and head adjustment.

An intensive care unit (ICU) is a special department of the hospital of health facility that provides intensive treatment medicine (Moris, 2000).
Intensive care unit cater to patient with severe and life threatening illness and injuries which require constant, close monitoring and support from specialize equipment and medications in order to ensure normal bodily functions they are staffed by highly trained doctors and nurses who specialize in caring for initial ill patients. ICU is also distinguished from normal hospital ward by a higher staff to patient ratio and access to advanced medical resources and equipment that is not routing available elsewhere. Patient may be transferred directing to an intensive care unit from an emergency department if revere of from a ward if they rapidly deteriorates of immediately after surgery if the surgery is very intensive and the patient is at high risk of complication (Smith, 2013).
One of the major equipment found in the ICU is the ICU, rehabilitation bed which is used for recovery, relaxation, sleep and rehabilitation most modern bed consist of a soft cushioned matures resting either on a solid basic often wood states or a spring base. Mainly beds include a box spring inner spring base, a large mattress. Sizes box containing wood and spring that proved additional support and suspension for the mattress (Farlex, 2012).
Beds are available in many sizes ranging from infant size, child or adult size, queen and kings size bed designed for two adult. Most bed are single mattresses on a fixed frame. There are other varieties such as the murphy bed, which folds out of a soft and the bunk bed, which provides two mattress on two tiers, temporary bed contain neither a padded mattress nor a bed train, such as the hammock and they are considered on of the most comfortable place to rest while swaying side to side. Many bed have a head board comforter, hand board only bed may incorporate a “dust ruffle” bed frame. To support the head, a pillion made of a soft padded materials is usually placed on the top of the mattress some form of covering blanket is often used to insulate the sleeper, often bed sheet a quiet of a duvet collectively referred it as bedding. Bedding is the removable non future position of a bed which enable these component to be washed or carried out certain standard are certain standard are necessary in other not to ad or inflict more paint to the patient that is already in paint , these bed have special feature both for the comfort and the well being of the patient and for the university of health care workers common feature include adjustable height for the entire bed the head and the feet adjustable side fail and electronic button and manual hand tact to operate both the bed and other heat by electronic device (William, 2011).
ICU bed and other similar type of bed are used not only in the hospital but in other health care facilities and home settings such as nursing home, assisted living facilities out patient’s clinic and in home health care. ICU bed with adjustable side first appeared in England sometime between 1815 and 1874 by Willest Dew attach of the department of surgery at Indiana university of medicine in the early 20th century this type of bed is sometime referred it as the gatch bed (Bedpan, 1945).
