Modular Aerosol Delivery System with Interchangeable Inserts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol delivery systems face challenges in accommodating different medicament container assemblies, requiring multiple dispenser housings and complicating the administration of various medications, especially when integrated into ventilator circuits.
Innovation Solution
A modular dispenser housing system that includes a support block with a well and orifice, allowing for the use of interchangeable insert members to accommodate differently shaped container assemblies, enabling a single dispenser housing to support multiple container configurations and medications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dispenser housing is shaped to receive a specific container assembly configuration, then proper actuation and support are ensured, but the dispenser housing cannot accommodate different container configurations
Solution Approach 1:
The dispenser housing is divided into a fixed outer housing and a removable insert member. The insert member can be exchanged to accommodate different container configurations, while the fixed housing provides stable actuation mechanisms. This segmentation allows the system to maintain reliable actuation through the fixed housing while adapting to different containers via interchangeable inserts.
Solution Approach 2:
The fixed dispenser housing is designed with universal actuation features that can work with multiple container types. The housing includes actuator boots and support blocks that can accommodate different valve stem configurations, enabling a single housing to reliably actuate various container assemblies through standardized interfaces.
2Adaptability or versatility
If multiple dispenser housings are used to accommodate different container configurations, then all container types can be supported, but inventory complexity and device count increase
Solution Approach 1:
By segmenting the dispenser into a permanent housing and removable inserts, the system avoids needing multiple complete housings. Each insert can be optimized for specific container types while sharing the common fixed housing infrastructure, reducing overall device complexity and inventory requirements.
Solution Approach 2:
The insert member is nested within the fixed dispenser housing, allowing the smaller, configurable insert to reside within the larger, universal housing. This nesting approach enables multiple container configurations to be supported through a single housing structure by swapping inserts rather than deploying multiple separate housings.
3Duration of action of stationary object
If the dispenser housing is integrated into a ventilator circuit, then continuous medication delivery is enabled, but reconfiguration for different medications becomes difficult
Solution Approach 1:
The removable insert member provides a segmentation point that allows quick exchange of container configurations without disrupting the integrated ventilator circuit. The fixed housing maintains continuous connection to the ventilator while the insert can be swapped to change medications, enabling both continuous delivery and easy reconfiguration.
Solution Approach 2:
The insert member is designed to be pre-configured with specific container assemblies before insertion into the fixed housing. This preliminary preparation allows for rapid switching between medications by simply exchanging pre-configured inserts, making reconfiguration easy even while integrated into the ventilator circuit.
