Client: LOM Medical

Our Role

• Design and build a retractable-needle safety syringe that leverages the client’s patent portfolio. Their patents cover gas-cell technology that provides a low-cost, disposable power source for medical products.

Unique Features and Accomplishments

• Developed the first fully-functioning prototype of the gas-cell technology.
• Created a new safety syringe that uses the stored energy in the gas-cell to propel the needle back into the body of the syringe.
• Designed and incorporated key features including:
  • Usage procedures that mimics those of a regular syringe
  • Cost competitive with other safety syringes
  • Superior safety and lower actuation force than other safety syringes
• Incorporated creative, readily-manufacturable features that accomplish a five-step needle retraction operation that is actuated in a single step when the user depresses the plunger at the end of travel.

Expertise Employed
While all projects benefit from our development process and expertise in design, engineering, and in-house rapid prototyping, this project highlights our expertise in:

• Mechanical engineering
• Design for manufacturing
• Microfluidics and Fluid Dynamics
• Plastic Assembly Methods
