Single-Port Charging and Patient Interface for Isolated Medical Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical devices require separate external connections for power supply/battery charging and patient interface, leading to larger and more expensive designs due to the need for higher electrical isolation to ensure safety, especially in home healthcare environments with unreliable electrical power and untrained users.
Innovation Solution
A medical system with a single external electrical port that allows non-concurrent charging of the battery and interfacing with a patient-applied part, preventing simultaneous connection to AC line power and patient contact, thus reducing the need for additional insulation and creepage distance, resulting in a smaller and less expensive device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate external connections are provided for power supply/battery charging and patient interface, then the device can be connected to both AC line power and patient contact simultaneously, but the device requires higher electrical isolation which results in larger and more expensive devices
Solution Approach 1:
The patent combines the power cable connection and patient-applied part cable connection into a single electrical port, eliminating the need for separate external connections. This merging approach reduces the device's electrical isolation requirements, allowing for smaller device size while maintaining safety standards.
Solution Approach 2:
The single electrical port serves multiple functions: it can accept either a power cable for charging or a patient-applied part cable for patient interface, but not both simultaneously. This multi-functional design reduces the number of separate connections needed while maintaining adaptability.

AI summary
A medical system includes a patient-applied part, a medical device, a power cable, and a patient-applied part cable. The medical device may include a device housing, a rechargeable battery within the device housing, a control circuit within the device housing, a power circuit within the device housing, and an electrical port on the device housing for use in making electrical connections to the control circuit and the power circuit within the device housing. The power cable may have a first end configured to be electrically connected to an electrical power line and a second end configured to be removably connected to the electrical port. The patient-applied part cable may have a first end configured to be electrically connected to the patient-applied part and a second end configured to be removably connected to the electrical port.
