Electrode Headset Segmentation for Hygienic Multi-Patient Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrode headsets require frequent disconnection and sanitization between users, which is time-consuming and inefficient, and do not allow for continuous use with multiple patients while maintaining cleanliness and sterilization standards.
Innovation Solution
An electrode headset design featuring a detachable head covering and electrode assembly with releasable connectors, where the head covering protects the electrode assembly from skin contact, allowing for easy cleaning and replacement of electrodes between uses, and enabling the headset to remain connected to the analysis system during user changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electrode headset is disconnected and sanitized between users, then cleanliness and sterilization standards are maintained, but setup and cleaning time increases
Solution Approach 1:
The electrode headset is divided into three separable components: the head covering, the electrode assembly, and the electrodes. This segmentation allows each component to be independently handled - the head covering and electrodes can be quickly removed and sanitized or replaced, while the electrode assembly remains connected to the analysis system, significantly reducing setup and cleaning time between users
Solution Approach 2:
The electrodes are extracted as separate detachable components from the head covering and electrode assembly. This extraction allows the electrodes to be independently sanitized or replaced without affecting the head covering or electrode assembly, enabling rapid turnover between users while maintaining sterilization standards
2Reliability
If the electrode assembly is protected from skin contact, then cleanliness and sterilization standards are maintained, but device complexity increases
Solution Approach 1:
The head covering serves as an intermediary component between the user's head and the electrode assembly. It provides a protective barrier that prevents direct skin contact with the electrode assembly, maintaining cleanliness and sterilization standards. The head covering is designed with holes that allow electrode connectors to pass through and mate with the electrode assembly, creating a simple yet effective protective interface without adding significant complexity
3Productivity
If the headset allows continuous use with multiple patients, then productivity increases, but maintaining hygiene becomes difficult
Solution Approach 1:
The headset is segmented into removable components (head covering and electrodes) that can be quickly sanitized or replaced between patients. This allows the electrode assembly to remain connected to the analysis system for continuous use while the external components are refreshed for each patient, enabling both high productivity and hygiene maintenance
Solution Approach 2:
The head covering and electrodes can be designed as disposable components that are discarded after a single use, eliminating the need for complex sanitization processes. This allows continuous use with multiple patients while guaranteeing hygiene standards are met, as each patient receives a fresh, unused head covering and electrodes

AI summary
In general, innovative aspects of the subject matter described in this specification can be embodied in an electrode headset and methods of using an electrode headset. An exemplary electrode headset includes a head covering, an electrode assembly, and a plurality of electrodes. The head covering has a plurality of holes and the electrode assembly includes a plurality of first connectors arranged to align with the plurality of holes of the head covering. Each electrode has a second connector configured to releasably mate with one of the first connectors of the electrode assembly through one of the plurality of holes of the head covering.
