Patients using electrically adjustable hospital beds often adjust their posture or height multiple times a day, making a continuous power supply essential.
How do manually adjustable hospital beds work?
Although manually adjustable hospital beds do not require electricity, they still achieve adjustment functions through a mechanical structure.
1. Mechanical Transmission Principle
Manually adjustable hospital beds typically use a metal crank to drive a screw mechanism, controlling the lifting angle of different parts of the bed.
Nurses or family members can raise or lower the backrest or legrests by turning the crank.
2. Common Functions
• Backrest height adjustment (approximately 0°–75°);
• Legrest height adjustment (approximately 0°–40°);
• Overall height adjustment (available on some models).
3. Advantages and Disadvantages
Advantages:
• No power supply required, suitable for areas with power outages or no electricity;
• Stable structure, virtually indestructible;
• Simple maintenance, low cost.
Disadvantages:
• Laborious operation, especially when caring for elderly or critically ill patients;
• Adjustments are not smooth or precise enough;
• Frequent adjustments may cause mechanical wear.
Manually adjustable hospital beds are more suitable for temporary care or home use on a limited budget.
What types of electrically adjustable hospital beds are available?
Based on functional complexity and power system configuration, electrically adjustable hospital beds can be mainly divided into the following categories:
1. Single-motor adjustable hospital beds
• Controls backrest height;
• Simple functions, suitable for short-term rehabilitation;
• Affordable price.
2. Dual-motor adjustable hospital beds
• Adjustable back and leg angles;
• More flexible functions and greater comfort;
Commonly used in home care environments.
3. Triple-motor or multi-motor adjustable hospital beds
• Adjustable backrest, leg, and overall height;
• Some have a trendleenburg function;
Suitable for long-term bedridden patients or medical institutions.
4. Battery backup system beds
Some high-end adjustable hospital beds are equipped with backup batteries in addition to the power plug.
Allowing short-term operation during power outages, ensuring patient safety.
What are the power requirements for an electrically adjustable hospital bed?
To ensure safety and performance, electrically adjustable hospital beds have certain power requirements.
1. Standard Voltage and Power
• Generally uses AC 110V or 220V voltage;

• The socket should be close to the bed to avoid cord tangling;
• Do not share an extension cord with high-power appliances;
• Regularly check the power cord for wear or looseness.
Does an adjustable hospital bed need to be plugged in all the time?
1. It is recommended to keep it plugged in for daily use
Because patients may need to adjust their posture at any time, unplugging the power will affect timely operation.
Meanwhile, the control panel and remote control consume very little power in standby mode, preventing waste.
2. Temporary Disconnection During Power Outages
If the adjustable bed will not be used for an extended period (e.g., during outings or cleaning), the power can be unplugged to prevent moisture or electric shock risks.
3. Models with Battery Backup Can Continue to Use During Power Outages
Some adjustable beds are equipped with lithium or lead-acid batteries, providing several hours of emergency use.
Are Electric Adjustable Beds Better Than Manual Beds?
