Wristguard for Tremors

On June 6th, I discovered that a "pull" action might work better than a "push" approach; refer to the attached Far Side cartoon for clarification. To ensure smooth plunger movement, I specifically selected a rigid barrel syringe, such as Merit Medical's Medallion model. Although a dedicated linear damper could enhance durability in a prototype, it is not necessary. This concept draws inspiration from roller skater wrist guards, utilizing 1cc disposable syringes as cylinders and employing luer connectors to fine-tune performance by adjusting damping versus range of motion. One-way valves, pressure relief valves, and tubing can be used to link opposing syringes. The affordability and replaceable nature of syringes and luer fittings make this design cost-effective. I apologize for the drawing's simplicity in Word, as I am still learning Inventor.
