Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for monitoring glucose levels in diabetic patients are cumbersome and infrequent, leading to delayed detection of hyper- or hypoglycemic conditions, which can result in dangerous health consequences due to the lack of timely and accurate insulin therapy decisions.
Innovation Solution
An integrated system comprising a medicament injection pen and a continuous glucose sensor that processes sensor data to calculate and deliver appropriate medicament therapy, providing real-time glucose monitoring and medicament administration, with features like user interface for input and output of data, graphical representation of glucose levels, and validation before medicament injection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional finger pricking methods are used for glucose monitoring, then the patient can obtain glucose level data, but the method is uncomfortable and inconvenient leading to infrequent measurements (2-4 times per day)
Solution Approach 1:
The patent combines the continuous glucose sensor with the medicament injection pen into a single integrated device. This merging eliminates the need for separate monitoring and treatment devices, making the system more convenient to use and encouraging more frequent monitoring by reducing the operational burden on the patient.
Solution Approach 2:
The integrated device automatically processes sensor data and calculates medicament therapy requirements without manual intervention. The system self-monitors glucose levels continuously and self-determines the appropriate insulin dosage, reducing the effort and discomfort associated with manual finger pricking and calculation.
2Reliability
If glucose monitoring frequency is increased to detect hyper- or hypoglycemic conditions timely, then dangerous side effects can be avoided, but the complexity of the monitoring system increases
Solution Approach 1:
By integrating the continuous glucose sensor, data processing electronics, and medicament delivery mechanism into a single device, the patent reduces the overall system complexity despite enabling continuous monitoring. The merged design eliminates the need for multiple separate devices and simplifies the user interface.
Solution Approach 2:
The system continuously monitors glucose levels and provides real-time feedback to automatically adjust medicament therapy. This closed-loop feedback mechanism ensures timely detection and response to hyper- or hypoglycemic conditions while automating the decision-making process, reducing the complexity burden on the user.
3Ease of operation
If manual calculations for insulin therapy decisions are performed, then the patient can determine appropriate therapy, but human error increases leading to dangerous situations
Solution Approach 1:
The integrated device automatically calculates the appropriate medicament therapy based on processed sensor data, eliminating manual calculations entirely. The system self-determines dosage requirements using embedded algorithms, ensuring consistent and accurate therapy decisions without human error.
Solution Approach 2:
The system uses real-time glucose sensor data as feedback to automatically adjust and calculate precise medicament dosages. This automated feedback loop ensures accurate therapy decisions by continuously comparing actual glucose levels against target ranges and adjusting the insulin delivery accordingly, removing the need for manual intervention.

AI summary
An integrated system for the monitoring and treating diabetes is provided, including an integrated receiver/hand-held medicament injection pen, including electronics, for use with a continuous glucose sensor. In some embodiments, the receiver is configured to receive continuous glucose sensor data, to calculate a medicament therapy (e.g., via the integrated system electronics) and to automatically set a bolus dose of the integrated hand-held medicament injection pen, whereby the user can manually inject the bolus dose of medicament into the host. In some embodiments, the integrated receiver and hand-held medicament injection pen are integrally formed, while in other embodiments they are detachably connected and communicated via mutually engaging electrical contacts and/or via wireless communication.
