The Unifill^TM Prefilled Syringe (also known as the Ready-To-Fill-Syringe or RTFS) has been engineered for mass production on the current filling and packaging systems of pharmaceutical partners. Key product advantages which Unilife believes can significantly disrupt the status quo of the pharmaceutical market for prefilled syringes include:

• Premium Protection
  The highly distinctive automatic (passive) needle retraction system within all Unifill^TM syringes virtually eliminates the risk of needlestick injury. Furthermore, the ability for operators to safely control the rate of needle withdrawal directly from the body can help minimize patient discomfort and the risk of acquiring a blood-borne infection via other potential transmission modes such as aerosol


• Retrofitting onto existing filling lines
  The Unifill^TM Prefilled Syringe is a similar size to standard non-safety prefilled syringes and supplied in the three standard sub-assembly pieces to minimize the time and cost required by pharmaceutical companies to retrofit the product onto current filling lines. This can help pharmaceutical customers minimize the costs of compliance with sharps safety laws by eliminating the need to purchase additional ‘clip-on' safety products for attachment onto standard prefilled syringes 


• Integrated Safety Features
  Unlike conventional safety products which are attached onto a standard prefilled syringe, all safety features in the Unifill^TM Prefilled Syringe are fully integrated into the core device design. Because Unifill's safety features are fully integrated, the product is compact in size, simple to use and can offer convenient, cost-effective disposal


• Expanding Drug Marketability
  The premium safety benefits and ease-of-use of the Unifill^TM Prefilled Syringe can allow pharmaceutical customers to enhance the promotion of current and pipeline drugs suitable for self-administration by patients in their home


• Increased Competitiveness
  The Unifill^TM Prefilled Syringe can offer pharmaceutical companies a significant market differentiator to promote the use of their injectable drugs and vaccines in competitive drug arenas-particularly when a product is approaching patent expiry or under pressure from generic competition

Unilife is not aware of any other prefilled safety syringe with a passive, user-controlled needle retraction mechanism that is fully integrated into the device. Unilife considers that the Unifill^TM Prefilled Syringe is consequently in a strong position to become a next-generation prefilled safety syringe technology.
