Preloaded CGM Sensor Applicator for Simple, Hygienic 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 easy attachment to the skin via a single-operated applicator, and a semi-permanent transmitter connected to the sensor module for continuous use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate transmitter is provided as disposable, then contamination is prevented, but cost increases and efficiency decreases
Solution Approach 1:
The system is divided into two functional segments: a disposable sensor module that contacts the body and prevents contamination, and a reusable transmitter that processes and communicates data. This segmentation allows the transmitter to be separated from the disposable component, eliminating waste while maintaining hygiene.
Solution Approach 2:
The transmitter is designed as a universal device that can be reused across multiple sensor modules. It performs multiple functions including data reception, processing, and communication, making it a multi-functional component that serves the entire glucose monitoring system rather than being discarded with each sensor.
2Reliability
If complex operations are required for attaching sensor module, then attachment reliability improves, but ease of operation deteriorates
Solution Approach 1:
The sensor module and applicator are merged into a single integrated unit. The sensor module is pre-installed within the applicator, combining the attachment device and sensing device into one component that performs both functions, thereby simplifying user operations while ensuring reliable attachment.
Solution Approach 2:
The sensor module is pre-installed in the applicator during manufacturing, and the applicator is pre-configured with all necessary components for attachment. This preliminary preparation eliminates complex assembly steps during use, allowing users to simply operate the pre-assembled unit for reliable sensor deployment.
3Measurement precision
If sensor module and applicator are made disposable, then measurement precision and safety improve, but cost increases
Solution Approach 1:
The system segments the disposable components (sensor module and applicator) from the reusable transmitter. Only the parts that directly contact the body and may become contaminated are made disposable, while the electronic processing components are reused, thereby maintaining measurement precision while reducing waste.
Solution Approach 2:
The sensor module and applicator are designed as inexpensive, disposable components that are replaced regularly to ensure measurement precision and safety. Their low cost allows for frequent replacement without significant expense, while the more expensive transmitter is preserved for long-term use.

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.
