An effective, low cost solution for vaccines
Leveraging Stress Engineering’s device development approach to utilize low cost/high volume packaging, Force-4 developed a dual chamber device for injection. This approach seeks to minimize the end cost of goods after the injector is fully developed. The impact of this device is an effective, low cost solution, that is intuitive to operate and applicable for global vaccination use.
Dual-chamber injector construction
Safety
The design centers around minimizing steps in operation to eliminate use errors. Flexure is sequential in use, and only in one particular order of operations. It cannot be used out of sequence or in reverse. It also cannot be repurposed for another injection purpose.
Product construction
The construction and activation through folds that increase pressure from one bullhead to the next is such that each operation cancels out the previous and is not able to be done in reverse. Flexure is intended to only work one way.
The Flexure difference
Sealed Film Construction – forming dual chambers
Frangible Membrane – area between 1st and 2nd bulkhead
Offset Fluid Entry – creates a wave and encourages mixing for reconstitution
Needle Assembly – welded to films
