A patient’s portable bed defined as a very special designed bed used for patients denotes the “special design” of such a device which has typical features meeting the needs of a bedridden patient. It is also defined as an advanced device or mechanism used to carry and transfer a patient’s body which is typically developed to meet the patient’s physical demands such as mobility or movement. A new method in a rehabilitation bed for transporting a bedridden patient is developed and applied to avoid staying at hospital with costly medical treatment and such obstacles, therefore to conquer these problems, the proposed design of the bed is formulated based on literature survey as well as consult the medical staff. This paper discusses the specification ,mechanism design and evaluating healthcare activities for development of a new style of active bed that provides high mobility with comfortable sleeping for bedridden persons and it also can meet the demands of those who may be required to take hospital beds to use at home particularly in a case of nursing disabled persons.

Today, the use of solar energy is expanding and developing because this energy is easily available and there are various technologies for producing thermal and electrical energy and cooling. One of the most energy-consuming parts is heating and cooling systems in residential buildings, which includes the major part of energy consumption in buildings. Therefore, in this research, the purpose of this research is to produce thermal energy for the cooling system using solar energy, which was used for analysis using Trnsys software, the purpose of this simulation is to check the thermodynamic parameters of the fluid and economic analysis, taking into account biological pollutants. The environment of the system has been considered. One of the important results of this research is the return on investment of 4 years, in which the required amount of energy supply through the solar system is 0.94.
