Hospital Bed

Overview

An electric hospital bed positions a patient for care, comfort, and safety while supporting nursing tasks and patient transfer. Powered actuators raise and lower the whole bed and independently articulate the backrest and knee sections, letting staff achieve sitting, supine, Trendelenburg, and chair-like positions, and lower the deck to reduce fall injury. Integrated weighing, fall-prevention rails, and a battery backup distinguish a modern acute-care bed from a simple frame.

Load is carried by the Base Frame, a welded steel base on braked, swiveling casters with corner bumpers. Above it the Lift Mechanism raises and lowers the sleep surface, and the Mattress Platform forms the four-section articulating mattress platform whose head, thigh, and foot segments hinge independently.

How it works

Every motion is produced by a Linear Actuator, a 24 V DC linear drive built on a common motor-and-leadscrew core that pushes against a section pivot until an end-of-travel limit switch stops it. The drives are commanded by the Control System, which houses the control box, hand pendant, and the battery backup that keeps the bed movable during a power failure. A mechanical CPR release lets staff drop the backrest flat instantly for resuscitation, bypassing the motor.

Fall prevention and patient control come from the Side Rail assemblies, split rails with caregiver and patient control pads built into them. The Bed Scale weighs the patient in place using load cells under the deck, important for fluid and drug dosing without moving an unstable patient. A pressure-relief Mattress completes the bed, and removable head and foot boards give access for transfer and codes.
