PenInject -Model 2.25 -Autoinjector

Our journey into the autoinjector industry began in the mid-1990s when a Swedish pharmaceutical company tasked us to design and manufacture an easy-to-use injection device to work with its lyophilized treatment. The treatment was already approved in the vial and prefilled syringe format for 2.25 mL dosing, and the injector needed to complement the original packaging to enhance the user experience.

SHL’s PenInject 2.25 was among the industry’s first to have successfully transformed a syringe-based drug product into an easy-to-use autoinjector. As a reusable, button-activated device, it offered a more intuitive alternative to the original self-injection method, including a mechanism that kept the needle hidden during the injection process. Importantly, PenInject 2.25 was given a sleek, elegant, and discreet pen-like design, affording patients an extra sense of privacy associated with their treatment. As SHL’s first injection project, PenInject 2.25 continues to represent SHL’s dedication to designing products that are centered around the patient.
