Therapeutic Infusion Adaptor with Septum for Interchangeable Pump Styles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Therapeutic fluid delivery systems, such as insulin pumps, often require frequent adherence changes and lack flexibility in attachment methods, leading to inconvenience and increased costs due to the need for separate devices for patch and pager-like styles.
Innovation Solution
A therapeutic system with a fluid delivery device, an adaptor for infusion sets, and a cradle that allows for interchangeable use between patch and pager-like styles, featuring a plug with a septum for reduced waste and adaptable adhesion, enabling remote operation and various attachment methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a therapeutic system uses separate devices for patch and pager-like styles, then each device can be optimized for its specific function, but the overall system complexity increases and cost increases
Solution Approach 1:
The pump device is designed with a universal interface that can accommodate both patch-style and pager-style configurations through a single adapter mechanism. The outlet port with adaptor septum allows the same pump to connect to different infusion set types, enabling one device to serve multiple functions that previously required separate devices.
2Reliability
If adherence location cannot be changed for about 3 days, then the adhesive maintains secure attachment, but the subject experiences inconvenience and may require frequent device replacement
Solution Approach 1:
The system transitions from a static adhesive attachment (fixed for 3 days) to a dynamic reconfigurable system where the pump can be detached and reattached to different locations. The adapter mechanism enables easy disconnection and reconnection, allowing the subject to move the device to a more comfortable location without compromising the adhesive's secure attachment capability.
3Ease of operation
If the pump is designed as a small patch device, then it can be worn comfortably on the body, but it lacks the ability to connect to infusion sets for remote fluid delivery
Solution Approach 1:
An adapter serves as an intermediary component between the small patch pump and the infusion set. The adapter includes a plug that attaches to the pump's outlet port and an adaptor septum that can be pierced by the infusion set lumen. This intermediary enables the small patch device to connect to infusion sets, combining the wearability of patch devices with the remote delivery capability of infusion sets.
4Ease of operation
If the outlet port is formed on an exterior surface of the fluid delivery device, then it is accessible for connection, but it may be vulnerable to contamination or damage
Solution Approach 1:
The outlet port is equipped with an adaptor septum that provides a protective barrier before connection. The septum can be pierced by the infusion set lumen in a controlled manner, and the adapter structure protects the port from external contamination. This preparatory protection reduces the risk of contamination while maintaining accessibility for connection.

AI summary
A therapeutic system in an exemplary embodiment comprises a fluid delivery device having a fluid reservoir, an outlet port with a lumen for outputting fluid from the reservoir, a pump for pumping the fluid through the lumen and a controller for controlling the therapeutic system. The therapeutic system may also comprise an adaptor for an infusion set, the adaptor having a plug operable for attaching to the outlet port, and wherein the adaptor has an adaptor septum operable for being pierced by the lumen when attached to the outlet port. The therapeutic system comprises an infusion set recognition system, wherein the controller is operable to query the infusion set recognition system for infusion set data, wherein the infusion set data comprises an infusion set type, wherein the controller is operable to operate the pump to provide a basal dosage of the fluid if the infusion set type is not recognized.
