Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electro-manual therapy methods cause patient discomfort due to abrupt current flow interruptions during contact breaks and re-establishments, lacking a seamless integration of electrical stimulation with manual therapy.
Innovation Solution
An electrotherapy system that automatically senses contact breaks and ramps down the electrical current, ensuring patient safety and comfort by integrating electrotherapy with manual therapy, allowing the practitioner to be part of the electrical pathway or using a conductive tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the practitioner becomes part of the electrical circuit delivering current through their hands or conductive glove, then the integration of electrotherapy with manual therapy is achieved, but the abrupt start or stop of current flow during contact breaks and re-establishments causes discomfort or shocking sensation for the patient
Solution Approach 1:
The system performs preliminary detection of contact status between the practitioner and patient before current delivery. The contact sensor continuously monitors the electrical pathway and triggers advance warning or preparation protocols when contact is detected, allowing the system to anticipate current delivery and adjust timing to prevent abrupt starts that cause patient discomfort.
Solution Approach 2:
The system implements continuous feedback through contact sensors that monitor the practitioner-patient contact state in real-time. This feedback loop allows the control circuit to detect when contact is made or broken and automatically adjust current delivery parameters, ramping up or down smoothly to prevent abrupt changes that cause shocking sensations.
2Reliability
If the system automatically senses contact breaks and ramps down current, then patient safety and comfort are improved, but the device complexity increases due to additional sensing and control mechanisms
Solution Approach 1:
The contact sensor serves multiple functions: it detects practitioner-patient contact for safety monitoring, triggers current delivery timing, and provides feedback for automatic current adjustment. By making the sensor multi-functional, the system reduces the need for separate dedicated components for each function, thereby limiting the increase in overall device complexity while maintaining high reliability.
Solution Approach 2:
The system performs self-monitoring and self-regulation through integrated sensors and control circuits that automatically detect contact status and adjust current delivery without external intervention. The practitioner simply needs to maintain physical contact, and the system handles the safety monitoring and current management autonomously, reducing the need for additional complex external safety devices.
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
Ensures safe and comfortable delivery of therapeutic electrical current by automatically adjusting current levels upon contact changes, enhancing patient safety and simplifying the treatment process for practitioners.
Implementation Method 1
The signal generator is electrically connected to at least one electrode configured to be attached to a body part of the practitioner... allowing the practitioner to become part of the electrical pathway
Implementation Method 2
The signal generator is further configured to detect a disengagement of the conductive interface from the patient and, in response, automatically ramp down the therapeutic electrical current
Data Source
AI summary
A system and method for performing electro-manual therapy is disclosed. In one embodiment, an electrode is attached to a practitioner, allowing the practitioner to deliver current through his hand or a bare-handed grip on a conductive tool. In another embodiment, an electrode is attached directly to the conductive tool, which can be held by a practitioner with a gloved hand. For all embodiments, a signal generator can automatically detect when contact with the patient is broken and ramps down the current to ensure patient comfort. This allows for the safe, effective, and simultaneous application of manual therapy and electrical stimulation.
