Adaptive Multimodal ICU Communication System for Intubated Patients
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patients in ICU settings, particularly those intubated, face difficulties in communicating their needs and feelings to medical professionals due to the inability to speak, with existing communication methods being inadequate or inefficient.
Innovation Solution
A communication system comprising a cylindrical hand-operated input device that converts mechanical motion into electrical signals, a general-purpose programmable computer to interpret and process these signals, and a display device for visual or audible output, allowing patients to communicate effectively with medical staff despite physical limitations and language barriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional communication methods (paper pad and writing instrument) are used for intubated patients, then the patient can communicate basic needs, but the communication process is time-consuming and inefficient
Solution Approach 1:
The patent replaces the mechanical writing system (pen and paper) with an electronic communication device that uses voice recognition, touch screen, or button-based input to generate digital messages, significantly reducing the time and effort required for communication
Solution Approach 2:
The patent introduces a communication device as an intermediary between the patient and healthcare providers, translating patient inputs (voice, touch, or button presses) into structured messages that can be quickly understood and acted upon by the medical team
2Productivity
If a communication device is introduced to improve patient communication, then communication efficiency improves, but the device complexity increases
Solution Approach 1:
The patent designs a communication device that can operate in multiple modes (voice recognition, touch screen, button input) and serves various functions (message composition, urgency indication, family notification), allowing a single device to replace multiple separate tools while maintaining ease of use
Solution Approach 2:
The patent divides the communication device into modular components including input interfaces, processing units, and output mechanisms, allowing the system to be configured based on patient needs while keeping each component simple and manageable
3Adaptability or versatility
If adaptive features are added to accommodate various physical deficits, then the system becomes more versatile, but the device complexity increases
Solution Approach 1:
The patent implements dynamic adaptability where the device automatically adjusts its interface and input requirements based on detected patient capabilities, such as enabling voice recognition for patients with motor difficulties or simplifying to button presses for patients with cognitive impairments, without requiring complex manual reconfiguration
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables patients to express their needs and feelings directly to medical professionals, accommodating various physical deficits and language differences, improving communication efficiency and reducing errors in patient care.
Implementation Method 1
a cylindrical hand operated input device configured to accept input conveyed by mechanical motion and configured to convert the input conveyed by mechanical motion into an electrical signal

AI summary
A communication system for use by individuals whose ability to speak is restricted, such as intubated patients in a hospital setting. Apparatus is provided to allow such a person to input his or her responses to topics of interest and thereby to communicate with others, such as medical professionals. In some embodiments the input is a joystick-like device that allows selections to be made in response to displayed option on a screen. In some embodiments, a digitally operated setoff keys is provided. The user's inputs are processed in a general purpose programmable computer that operates under the control of a set of non-volatile instructions recoded on a machine-readable medium.
