Solution Overview

Problem

Current CT scanning processes for stroke diagnosis often result in delays due to the need to transport patients from the emergency room to the radiology department, which can exceed the critical 3-hour window for effective treatment, especially since conventional CT machines require patients to be moved and cannot accommodate standard hospital beds or gurneys.

Innovation Solution

A mobile CT system, such as the CereTom, and an X-ray transparent bed and gurney extender that allows for scanning on-site in the emergency room, enabling the CT machine to be positioned next to the patient and using an extender to support the patient's head during scanning, thus eliminating the need for patient transport and accommodating standard hospital beds or gurneys.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If a conventional CT machine is used, then imaging capability is provided, but patient transport time increases significantly

Engineering Contradiction:
Improvepatient transport timeVSAvoidcompatibility with standard hospital beds
Core Design Contradiction:
Loss of timeVSAdaptability or versatility

Solution Approach 1:

The support system is divided into separate modular components including head support, body support, and adapter elements that can be independently attached to standard hospital beds, allowing the CT machine to remain stationary while providing imaging capability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

An adapter serves as an intermediary component that connects the custom support structure to standard hospital bed mechanisms, enabling compatibility without requiring modification of either the CT machine or the hospital bed

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of time

If the CT machine is positioned next to the patient on the bed, then transport time is reduced, but the support structure must be X-ray transparent

Engineering Contradiction:
Improvediagnosis timeVSAvoidsupport structure material requirements
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The support structure materials are selected and designed to be transparent to X-ray frequencies, changing the material parameter to allow passage of imaging radiation while maintaining structural support functionality

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The support structure utilizes composite materials that combine mechanical strength with X-ray transparency, such as carbon fiber or specific plastic compositions, achieving both structural and imaging requirements

Inventive Principle:
Principle #40Composite materials
