The Hospria iSecure syringe wins the IDSA/Plastics News Design Award for 2009. The innovative use of materials, molding and intuitive design made this solution “the complete package”, says the panel of judges.
This four-component device is actually shot within one single injection mold using three different materials. Opposed to conventional multi-shot molding (lik overmolding), these polymers will not bond to each other in any combination. The device is molded in three separate positions within the mold with one position molding two of the four components. The first shot – the clear body of the device, is a copolyester. The requirement for this component was to be water clear and protective as it encapsulates the sterile drug cartridge that is assembled into this device for final product. The second material was for the plunger, that required stiffness for which a polypropylene was selected. The final polymer that forms the “Tamper Band and Cartridge Clamp” was a delicate combination of opposing requirements which a middle of the road solution was required to balance out the criteria. For this a low density polyethylene was selected that allowed for the “Tear Band” to be flexible and to be able to tear (think the rip tap on a milk bottle cap), creating the tamper evident feature and the “Cartridge Clamp” which required a living hinge and a strong snap feature. This is a great example of the designer and engineer using materials and processes tocreate a truly complete and intuitive product.
Congratulations to the team at Hospira!
