Mobile Patient Bed with Motorized Axis Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical procedure beds are often large, heavy, and fixed, which hinders efficient workflow in medical and surgical procedures, as they occupy significant space and limit the ability to move patients between different stages of treatment without delaying other procedures.
Innovation Solution
A mobile patient bed system equipped with motors for independent axis positioning, actuators for bed adjustments, and communication devices for wireless connectivity with medical systems, allowing for seamless movement and positioning of patients between different stages of medical procedures while maintaining integration with surgical systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beds are made large and fixed to the system, then stability and integration with medical systems are improved, but mobility and space efficiency deteriorate
Solution Approach 1:
The bed is designed with motorized positioning systems that allow it to dynamically adjust its position and orientation. The bed can be moved between different locations (procedure room, recovery area, imaging area) and adjusted to various angles (Trendelenburg, reverse Trendelenburg, lateral tilt) to meet different procedural requirements, resolving the contradiction between stability and mobility.
Solution Approach 2:
The bed serves multiple functions: it can be used for patient preparation, laser surgery procedures, recovery, and transport between different areas. The integrated communication device enables the bed to work with various medical systems (laser systems, imaging systems), making it a universal platform that replaces multiple separate fixed beds.
2Productivity
If beds are fixed to the system, then workflow integration is improved, but flexibility and adaptability deteriorate
Solution Approach 1:
The bed incorporates motorized actuators that enable dynamic positioning in multiple degrees of freedom (vertical movement, lateral tilt, Trendelenburg positioning). This dynamic capability allows the bed to adapt to different procedural requirements while maintaining seamless integration with the medical system through wireless communication.
Solution Approach 2:
Traditional mechanical linkages and manual adjustment mechanisms are replaced with motorized positioning systems controlled through wireless communication. This substitution enables more precise and flexible positioning while reducing mechanical complexity and improving responsiveness to control commands.
3Productivity
If multiple beds are used for different procedure stages, then workflow continuity is improved, but space requirements and device complexity deteriorate
Solution Approach 1:
A single bed is designed to perform multiple functions across different procedure stages (preparation, surgery, recovery). The bed can be repositioned and reconfigured for each stage, eliminating the need for multiple separate fixed beds and reducing overall space requirements while maintaining continuous workflow.
Solution Approach 2:
The bed's dynamic positioning capabilities allow it to be quickly reconfigured between different procedural stages. Motors can adjust the bed's position and orientation to suit different requirements, enabling one bed to replace multiple static beds and improve space utilization.

AI summary
A mobile patient bed may be used for moving a patient between at least two locations during a medical procedure. The mobile patient bed may comprise an interface configured to selectively couple the mobile patient bed to at least one medical system and at least one processor configured to receive a medical system command via the interface and process the medical system command when the mobile patient bed is coupled to the at least one medical system, receive and process a user command when the mobile patient bed is not coupled to the at least one medical system, and refrain from processing the user command when the mobile patient bed is coupled to the at least one medical system. The mobile patient bed may also comprise a seat and a plurality of motors configured to independently position the seat along a plurality of axes.
