The world's population is ageing. In fact, every country in the world is experiencing a high rate of growth in the number and percentage of older individuals in the entire population. This has become one of the most significant social changes of the twenty-first century (Lutz et al 2008). According to statistics from World Population Prospects: the 2017 Revision, the number of older adults aged 60 and over is expected to double by 2050 and triple by 2100. The number will rise from 962 million in 2017 to 2.1 billion in 2050 and by 2100, the number will be 3.1 billion. The aging population is growing faster than the younger population (Lutz et al 2017). Most of these elderly people are forced to stay in bed due to some health problems. In many cases they are forced to live in bed due to illness or infirmity. Many of these subjects require special care to avoid the development of pressure ulcers which can be caused by prolonged stay in the same physical posture. This can lead to death if the individual is not turned regularly as the pressure applied to the skin can prevent blood from flowing into the pressed skin region (Ikezoe et al 2011). This can be avoided by using special beds which in many cases are very expensive. Many people who are bedridden for various reasons cannot afford such beds. It is necessary to design a special bed that allows bedridden people to move (Cameron et al 2012). Furthermore, the options available for moving these people have numerous flaws in their management or use. Most of them have limited operational capabilities which make them useless in some situations (Yukawa et al 2010). Therefore, the main objective of this project is to develop a mechatronic system that gives a bedridden individual the ability to get out of bed and do basic things such as bathe and help the people who care for him to pick up the necessary physiological data of the patient.Say no to plagiarism.

Many of these individuals suffer from various diseases, most of which are brain-related. Brain diseases account for nearly 50% of all cases. Furthermore, the number of elderly people is increasing worldwide. Data collected by World Population Prospects: Revision 2017 indicates that the number of older adults aged 60 and over is expected to double by 2050 and triple by 2100. The number will increase from 962 million in 2017 to 2.1 billion in 2050 and In 2100 the number will be 3.1 billion. Unfortunately, many of these sick and elderly people are very poor (Lutz et al 2017). Global poverty statistics have shown that nearly half of the world's population lives in extreme poverty. This means that 3 billion people live on less than $2.50 a day. 1.3 billion individuals live in extreme poverty. They spend less than $1.25 per day (Braithwaite & Mont 2009). many of the bedridden people are among the 3 billion poor. this means they cannot afford the expensive beds available to help them get around. Staying in bed for such a long time is also associated with numerous health effects, most of which are fatal if not managed in time. It can have effects, for example, on muscles and bones. When muscles are not used, they quickly begin to weaken and wear out and this can lead to death (Ikezoe et al 2011). Mission Statement Primarily, the systemmechatronic for bedridden people is aimed at helping both sick people who are unable to get out of bed and also the elderly. It will be able to collect them from bed and for bathing and other necessary healthcare operations such as collecting physiological data that will be used in the treatment of the patient. The system will be designed in such a way that it will have numerous functions. The mounted conveyor belt structure will help the bed move patients from one device to another. The system will be adjustable in various positions (Bezerra et al 2015 February). This means that it can have the same characteristics as those of the wheelchair. The system also aims to provide a certain independence of movement, thus improving the patient's physical and psychological health. Performance and physical parameters The system consists of a transport system that has the ability to lower or raise the patient on the lift and subsequently move the person on the stretcher without the involvement of swings. It has the ability to move the change into different positions like a wheelchair and move the patient (Bezerra et al 2015 February). Operational Requirements The mechatronic system bed will be available in different models. But the bed is specifically designed for just one person and can last more than 30 years if handled well. Usage Requirements The mechatronic system bed carries only one patient and can be used by a healthcare worker. Since most patients who will use the system may not be able to move, the system will allow them to bathe, move from one place to another and also provide the best safety for patients. Since the development of several beds will be envisaged, each customer (patient) will have to be aware of the needs and requirements they need such as adaptability, privacy, security and versatility. By developing the mechatronic system for bedridden people, it will be possible to avoid various diseases related to long periods of staying in bed (Peng et al 2010). Effective Factors The system will be designed in such a way that it is comfortable for all its users. The width of the bed will be approximately 90 cm, the depth of the seat will be 46 cm and the length of the mattress will be 210 cm. this is in an effort to make sure that bedridden people feel comfortable. The bed does not require a high level of technological know-how to be used easily. Anyone is able to use it thanks to its automatic features. The bed will also be designed to accommodate individuals of all heights, weights and heights. This is because they will be tailor-made taking into account the user's preferences. Regular maintenance of the bed will be carried out to ensure that it is in perfect condition (Brodersen et al 2015). Conceptual DesignDesign Alternatives The first option for the mechatronic system was the rotoflex rotating bed. The design allowed for electronic operation of the bed. It is adjustable in nature and provides motorized rotation to help the patient get in and out of bed. The bed helps people with mobility to access the bed alone and safely without the help of a companion. The bed is equipped with a button that allows the patient to move from an upright sitting position to a lying position and vice versa. The design was selected because its development cost was affordable and could be easily adjusted and used by the patient (Brodersen et al 2015). . [image: image result for rotoflex single bed rotation]The second design option was the patient lift and ceiling lift. The ceiling lift had a pre-established track while the patient lift had aindependent structure equipped with wheels. For this device to work efficiently, two healthcare professionals must be present to help the patient move (Schoenfisch et al 2015). The design has a portable motor that will allow the patient to travel from room to room and even take a cruise. They offer the convenience that the patient desires (Alamgir et al 2009). The project was rejected due to numerous safety issues related to it. For example, in situations where the mesh under the device breaks, it can cause serious harm to the patient. The third option was the inflatable bed bathtub. The bed had the option of being inflated by the use of a vacuum cleaner. The device was basically designed for the elderly. Is the shower head connected to the sink faucet and is the system drain hose connected to the sink drain? The design also has the ability to stimulate both the shower and the bathtub by discharging or not draining the water into the tub (Yukawa et al 2010). The design was not selected because it was expensive and specifically designed only for older people and not for anyone with mobility issues.[image: Image result for bedridden patients with inflatable bed bathtub]The last option was the design with medical terminal (MCT). The project had all the features such as analysis systems for monitoring the patient's health conditions (Pereira et al 2015). The project had the ability to collect information that could be used to monitor the patient's condition in real time. The data received can also be used to make various diagnoses on the patient (Pereira et al 2016). The project was rejected due to development costs. Once completed, the system would be sold for $8600. This means that the system may only be accessible to a wealthy few. [image: ]Modeling of the Selected Option The rotoflex swivel bed is designed to rotate in any specific direction preferred by the patient. This makes it compatible with any environmental situation. The model will be equipped with a device that will allow it to independently lift the headboard and footboard of the mattress. This will give the patient variable heights to stand and move around more easily. Please note: this is just an example. Get a custom paper from our expert writers now. Get a Custom Essay The technique will also help the caregiver raise the bed to a position that is safe for working (Silva 2015). The bed can switch between lying and sitting positions independently. For example, the Rotoflex 175 low has the ability to ensure a distance of approximately 43.5 cm between the floor and the surface of the mattress. This way, patients or elderly people with shorter legs will be able to sit more comfortably by leaning their butt against the back of the seat. Each rotoflex swivel bed will be designed to customer specifications. Some of them will be equipped with 50cm lift motors which will compensate for the low starting heights. The width of the bed will be approximately 90 cm, the depth of the seat will be 46 cm and the length of the mattress will be 210 cm. this is in an attempt to ensure that bedridden people feel comfortable (Brodersen et al 2015). ConclusionThe number of elderly patients with inability to walk has increased in recent years. Due to staying in bed for long periods, most of them have developed numerous diseases associated with this condition. This has necessitated the development of a mechatronic system for bedridden people that will allow them to move from one point to another. Four options were proposed during the bed development process. A.
