Working principle of electric medical bed

Electric medical beds are equipment used for patient care and treatment. They are commonly found in hospitals, clinics, and nursing homes. They are mainly used to provide a comfortable resting environment, facilitate operation by nursing staff, and adjust the bed position according to the different needs of patients. The working principle of electric medical beds mainly depends on electric motors and control systems, and can achieve various adjustments such as lifting and tilting of the bed through electric drive systems. The working principle of electric medical beds can be summarized in the following steps:

1. Electric drive system

The core part of the electric medical bed is the electric drive system. The system consists of multiple electric motors, each of which controls different parts of the bed. For example:

Lifting motor: controls the height adjustment of the bed so that the bed can be raised and lowered, which is convenient for nursing staff to operate or patients to enter/leave the bed.

Back adjustment motor: adjusts the tilt angle of the head of the bed to help patients adjust to different angles such as sitting and half-lying.

Leg adjustment motor: controls the lifting and lowering of the lower part of the bed to help adjust the angle of the legs.

Horizontal adjustment: Some beds are also equipped with the function of adjusting the horizontal angle of the bed to further optimize the comfort of the patient.

2. Control system

The control system of the electric medical bed enables users to adjust the position of the bed according to the needs of the patient. There are many ways to control:

Manual remote control: The most common way, caregivers control the adjustment of different parts through the remote control buttons.

Bedside control panel: A control panel integrated into the bedside, which is convenient for patients or caregivers to operate directly.

Wireless remote control: Some advanced electric medical beds allow the functions of the bed to be controlled by wireless remote control or smartphone APP.

The control system is usually equipped with buttons and displays that can show the current status of the bed and allow precise adjustment.

3. Power source

There are two main sources of power for electric medical beds:

DC power supply: Most electric medical beds use household power, which is converted into DC power by a transformer to drive the motor.

Battery: Some electric medical beds are also equipped with backup batteries to cope with power outages, ensuring that basic adjustments can still be made without power.

4. Safety protection mechanism

Modern electric medical beds are usually equipped with safety mechanisms to prevent operating errors or failures. For example:

Current overload protection: Prevents the electric motor from burning out due to overload.

Emergency stop function: The movement of the bed can be stopped immediately in the event of an abnormal situation.

Locking function: Prevent patients from misoperating, usually by locking the control buttons or various functions of the bed to protect patient safety.

5. Adjustment function

Electric medical beds can provide a variety of adjustment functions according to different patient needs:

Bed height adjustment: The height of the bed can be adjusted according to the needs of nursing staff, which is convenient for patients to get on and off the bed or for treatment.

Head lifting adjustment: The patient can adjust the angle of the head of the bed, which is suitable for patients who need to sit, lie, half-lying, recover, etc.

Leg adjustment: Adjust the leg angle of the bed to help relieve leg pressure, especially for patients who are bedridden for a long time.

In summary, electric medical beds use electric drive motors, control systems and transmission mechanisms to achieve precise adjustment of the position and angle of the bed to meet the different needs of patients and nursing staff, and are widely used in medical, nursing and rehabilitation fields.
