Preloaded Sensor Applicator Assembly for Simple CGM Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing continuous glucose monitoring systems require complex user operations for attaching sensor modules, and separate transmitters are often disposable, leading to inefficiency and potential contamination, especially for children or older users.
Innovation Solution
A sensor applicator assembly with a preinstalled sensor module and built-in battery, allowing for simple attachment to the skin using the applicator, and a separate transmitter connected to the sensor module for semi-permanent use, with a disposable design to prevent reuse and contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate applicator and sensor module are used, then the sensor can be attached to the skin, but the user operation becomes complex and time-consuming
Solution Approach 1:
The patent combines the applicator and sensor module into a single integrated assembly where the sensor module is preinstalled within the applicator body. This merging eliminates the need for separate handling and attachment steps, allowing users to simply operate the integrated device to attach the sensor to the skin, thereby reducing operational complexity and time requirements.
Solution Approach 2:
The sensor module is preinstalled in the applicator during manufacturing, so that when the user receives the device, the sensor is already in position and ready for attachment. This preliminary action eliminates the need for users to manually install or prepare the sensor separately, significantly reducing the time and complexity of the attachment process.
2Reliability
If a disposable transmitter is used with each sensor module, then contamination is prevented, but cost increases and waste is generated
Solution Approach 1:
The system is segmented into disposable and reusable components: the sensor module and applicator are designed as disposable units that are discarded after use to prevent contamination, while the transmitter is designed as a reusable component that can be used with multiple sensor modules. This segmentation allows contamination prevention while reducing waste and cost.
Solution Approach 2:
The disposable sensor module and applicator are discarded after a single use to ensure no contamination, while the transmitter is recovered and reused with subsequent sensor modules. This approach maintains hygiene standards while minimizing waste generation and reducing overall system cost.
3Ease of operation
If the sensor module is preinstalled in the applicator, then user operations are minimized, but manufacturing complexity increases
Solution Approach 1:
The sensor module is preinstalled in the applicator during the manufacturing process, which simplifies the user operation to merely operating the integrated device. While this preliminary assembly adds a step to manufacturing, it enables the simplified user experience and can be efficiently implemented through automated assembly processes.

AI summary
The present invention relates to a sensor applicator assembly for a continuous glucose monitoring system and provides a sensor applicator assembly for a continuous glucose monitoring system, which is manufactured with a sensor module assembled inside an applicator, thereby minimizing additional work by a user for attaching the sensor module to the body and allowing the sensor module to be attached to the body simply by operating the applicator, and thus can be used more conveniently. A battery is built in the sensor module and a separate transmitter is connected to the sensor module so as to receive power supply from the sensor module and be continuously used semi-permanently, thereby making the assembly economical. The sensor module and the applicator are used as disposables, thereby allowing accurate and safe use and convenient maintenance.
