Medical Ventilator Cart with Segmented Platforms for Independent Component Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical ventilator carts with stacked components require cumbersome removal procedures, delaying maintenance and posing challenges in busy hospital settings, and users often incorrectly handle the carts due to misplaced handles.
Innovation Solution
Design of medical ventilator carts with a base and vertical supports allowing independent placement and removal of components, such as a Breath Delivery Unit and display monitor, without needing to rearrange other components, and incorporating a cart handgrip for secure handling and maneuverability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If ventilator components are stacked upon one another on a wheeled cart, then the cart can support all components in a compact arrangement, but components in the middle or at the bottom cannot be easily removed requiring removal of components above them
Solution Approach 1:
The cart structure is segmented into multiple independent vertical support columns instead of a single stacked arrangement. Each support column can independently hold ventilator components, allowing any component to be accessed and removed without disturbing components on other columns. This segmentation transforms the single-file access problem into a parallel access system where multiple components are simultaneously accessible.
2Stability of the object's composition
If handles are located on the side of the cart to allow stacking of components between them, then components can be securely positioned, but users may incorrectly grasp and pull ventilator components instead of the handle
Solution Approach 1:
The handle is given distinctive visual and physical characteristics that differentiate it from ventilator components. The handle features a unique shape, color, or texture that makes it immediately identifiable as the correct grasping point. This local quality enhancement ensures users intuitively grasp the handle rather than mistaking any component for the handle, maintaining both secure component positioning and safe handling.
3Quantity of substance
If components are stacked vertically to maximize space utilization, then the cart accommodates more components, but maintenance time increases due to cumbersome removal procedures
Solution Approach 1:
The cart uses multiple independent support columns to segment the component arrangement space. This allows components to be distributed across different vertical zones that are independently accessible. When maintenance is needed, only the specific component requires removal, not the entire stack, thereby maintaining high component capacity while eliminating the time penalty of sequential unstacking.

AI summary
A medical ventilator cart, for use in hospitals or other medical settings, stores and transports various components of a ventilator system, such as a Breath Delivery Unit, a display monitor, and a compressor. First and second platforms are suspended above a base of the cart and allow the various ventilator cart components to be separately and independently placed on and removed from the cart without the need to move or rearrange any of the other ventilator components. One version of the cart provides an additional compressor platform attached to the base for mounting a compressor below the first platform.
