Best Linear Actuators For Hospital Beds

    Best Linear Actuators For Hospital Beds
    The humanity is striving for improvement. Anything that can be simplified or automated is a target for research and implementation. Most of the inventions were created within the last 150 years and the process is only picking up the pace. The introduction of linear actuators is one of the human creations that help us every day. In most cases, we are so used to the utilization of some mechanisms that we cannot imagine our lives without them anymore. Moreover, some of these devices are so strongly embedded in our routine, we wouldn’t know how to operate without them.

    What Are Linear Actuators?


    Linear actuators are specific devices that transform rotational movements into linear ones. Depending on the system, actuators can be mechanical, electric, hydraulic, etc. Those types are driven by different forces and might have a different application. Some of the devices might be more concentrated on the precise positioning while some others are designed to provide speed and force and the accuracy is not as important. Actuators are used in multiple spheres like engineering, logistics, gaming, medical, etc.

    The movements of actuators can vary according to the complexity and application field. This can be ascending, descending, pulling, blocking, and so on. The actuators come in various shapes and sizes. Lately, a big step has been made towards making actuators smaller. Each type of these devices has its advantages and disadvantages. For example, a mechanical actuator does not require a power source to operate. However, the operation can only be performed manually. Electric actuator, on the other hand, needs a power source and its parts can wear off pretty quick. But, at the same time, it can be automated.

    How Are Actuators Used In the Medical Field?


    In many cases, actuators are used for things we use on a daily basis. And, the medical field is no exception. In fact, it’s one of the biggest fields of actuators application. The medical field requires constant improvements. A lot of processes at the moment rely on automation, which shortens the time required for some actions and just makes them easier. As the hospitals and laboratories are dealing with people and sensible materials, the accuracy and speed are often at the essence.

    Linear actuators help to make a patient’s visit to the hospital more comfortable and staff work easier. Some of the examples include actuators for wheelchairs, hospital beds, dentist or gynecological chairs, etc. The actuators for chairs are generally only limited to lifting and descending. The devices for hospital beds and surgical equipment can be much more complex

    This is related in the first place to the specific requirements for these products. To ensure the required high performance of the equipment, the electric actuators are mainly used.

    Why Electric Actuator?


    There are a few reasons for using mainly electric actuators in medicine. They are based on the speed, accuracy, and load support.
    1. Most of the electric actuators support speed control. They are perfect for providing smooth movement. This is extremely important in the medical care as not to disturb the patients during procedures.
    2. Due to the speed control possibility, the better accuracy control is achieved. The precise positioning is an essential part of the medical equipment. This is especially true for the surgical and diagnostic equipment used in hospitals.
    3. Electric actuators are quiet and environmentally friendly. They do not produce noise and do not pollute the environment, which particularly makes sense for the medical care field. Besides, they are non-toxic and do not cause any harm to patients or hospital staff.
    4. They are easy to install compared to the hydraulic and pneumatic ones. This makes the system easier to implement.
    5. Electric actuators can be embedded into a system with sensors detecting movement, load, and position.
    6. Last, but not the least, such actuators are not very costly. Their affordable price allows the mass production and usage of devices.

    How Are Actuators Used In Hospital Beds?


    Hospital beds are one of the most important pieces of equipment in hospitals. The importance of a bed being comfortable and safe is extremely high. Modern beds are designed with a particular set of features to provide comfort to the patient and help the hospital staff manage things better. Depending on the specific requirements, the system for a hospital bed can contain multiple accessories. Those are based on the on the application of a particular bed within the hospital.

    The components for a bed system can include:

    Connecting cords
    Patient control system
    Staff control system (often supplied with a block option)
    The wheels for movement
    The mattress divided two or four parts with actuators installed into the frame
    Electric motor
    The number and sets of the components may vary according to the complexity of the system.

    The Main Applications Of Actuators For Hospital Beds


    The basic system for a hospital bed includes the possibility of adjusting head or leg position of the patient. The action can be performed with the help of the patient control system (a remote panel) or staff control system. The process of lifting of descending certain parts of the bed is smooth, not loud, and easy. The control panel is placed within a hand reach of the patient and is connected to the bed system with a cord.

    More complex systems can also include the work of sensors Sensors are connected to the system and the software. The software for such beds is designed to provide a possibility of an intelligent control over the patient. This is especially important for patients with severe disabilities or patients of mental institutions. Scanners can distinguish if the bed is wet, or if the patient is out of bed and notify staff about it. Some of the more advanced systems also have attendant control with a touchscreen or a battery backup option. The system can also include a sensor, notifying staff that the cable has not been plugged out when the bed is moved.

    Conclusion

    The improvements of the modern technology made our life easier and safer. They help us save time and money and thus improve our effectiveness and efficiency. The introduction of linear actuators into the medical healthcare is an important step forward. The actuators are a big help in saving time and showing high performance for hospitals. And, as the technology develops, new applications and opportunities are discovered for implementing actuators.
