How Smart Patient Beds Adjust Speed Based on Patient Needs

This patent describes a system for patient support apparatuses, like hospital beds, that can automatically adjust how fast their moving parts operate based on what a user inputs or what the patient's body needs.

What it covers

This patent outlines a patient support system that includes a patient support apparatus, such as a hospital bed. This apparatus has an actuatable device, which is a part that can move or perform specific actions. A controller is included to manage how quickly this actuatable device operates. The patent specifies that this rate of operation is adjusted based on either a user's input, like a caregiver's command, or a patient's condition, such as their movement or vital signs. For example, a bed might slowly recline if a patient is frail, or quickly adjust if a caregiver needs to reposition them urgently.

What it doesn't cover

• —Does not cover patient support systems that lack an actuatable device, such as a simple, non-adjustable bed.
• —Does not cover systems where the rate of operation of an actuatable device is not controlled at all, only turned on or off.
• —Does not cover systems where the control of the actuatable device's rate is not based on user input or a patient's condition, for example, if it's based purely on a pre-set timer.
• —Does not cover patient support systems where the actuatable device performs functions unrelated to the patient support apparatus itself.

The clever bit

The novelty lies in dynamically controlling the *rate of operation* of patient support devices, not just their activation, based on real-time user input or the patient's actual condition. This allows for nuanced, adaptive assistance rather than simple on/off functionality.

Why it matters

This technology aims to improve patient care by making support systems more responsive and safer. By automatically adjusting the speed of movements, it can prevent injuries, enhance comfort, and reduce the physical strain on caregivers. This approach allows for personalized care, adapting the equipment's function to the unique and changing needs of each patient.
