Cambridge Consultants, a product design and development firm, has created a new prefilled syringe that uses fewer resources to manufacture than many current models. Unsurprisingly, the green syringe was named Syreen, but its environmental credentials are only part of the features of the new device.
Instead of glass, Syreen syringes are made with COP (cyclic olefin polymer) plastic, which has enabled Cambridge Consultants to shed the need for secondary packaging altogether, a first in this medical device arena. The makeup of the Syreen allows syringes to clip together, nesting in a pack while the COP design doubles as the outer shell of the packaging itself. The Syreen therefore eliminates the need for wasteful fillers such as cardboard and styrofoam, reducing the packaging weight by 30 percent and volume by 50 percent from today’s standard packaging.
To use Syreen, simply unclip the prefilled syringe and put it against the desired area on the skin. After delivery, with a simple snap, the user ejects the needle into the sharps bin and allowing the user to potentially recycle the plastic capsule. Patient and healthcare provider safety is also increased due to two further features of the design. Firstly, the COP plastic syringe features a curved surface over the needle that, while keeping the syringe from rolling and reducing needle-stick accidents, also ensures overall stability and depth control during injection. Secondly, the design insures that, with separated plunger and stopper, it is impossible to take in blood or other contaminants, reducing the risk of cross infection.
