Ergonomic syringe attachment for healthcare professionals
Protecting the hands that care for others — one injection at a time.

Nurses and clinical staff administer hundreds of injections per shift. The repeated act of depressing a syringe plunger with thumb force places extreme, cumulative strain on the carpometacarpal (CMC) joint — the primary thumb joint.
“Some days my hand hurts so much I have to push the plunger with my palm — my thumb just doesn't do it anymore.” — ICU Registered Nurse, 14 years' experience
Carpometacarpal joint arthritis is a progressive degeneration of the thumb's base joint, accelerated by exactly the motion syringe plungers demand — a precise, repeated pinch-and-press.
Women have greater ligament flexibility, leading to thumb base instability — especially with repetitive movement.
Repeated pinching, gripping, or twisting — like syringe depression — is a primary driver of CMC degeneration.
Past fractures or sprains to the thumb can pre-dispose the joint to premature osteoarthritis.
Post-menopausal hormonal changes reduce joint support; arthritis often accelerates sharply after age 50.
Syringe Buddy is a compact, reusable ergonomic attachment that clips onto standard syringes in seconds. Instead of using thumb force to depress the plunger, the user drives it with their arm and bicep — the body's strongest, most durable muscle group.
No training program, no muscle memory to unlearn — just a different point of leverage.
“CMC arthritis from repetitive pinch-grip activities is a well-documented occupational hazard for healthcare workers. A device that redirects syringe force away from the thumb joint is both clinically sound and long overdue. I am proud to endorse Syringe Buddy.”Dr. Peter DeNoble — Hand & Upper Extremity Surgeon, Clinical Advisor
