FAQs

Q1: Are Control Rings reusable?

Control Rings are engineered for strength and precision.

Best practice is single-patient use, ensuring the highest standards of hygiene, clinical care, and patient trust. However, we recognize that not every injector setting allows strict single-use. For those cases, we provide a sanitation guide to support responsible, safe reuse when appropriate. Many injectors reuse their rings for 3–5 sessions or more, depending on handling, sanitation, and professional discretion. Control Rings are physically resilient — but your clinical excellence, patient trust, and professional standards always come first.

Q2: Will the Control Ring fit my syringe model?

Each Control Ring is custom-matched to specific syringe platforms — no adjustments, no guessing. Choose your preferred brand during ordering for a precision fit.

Q3: How does the Control Ring attach to the syringe?

Snap-fit attachment. No tools. No recalibration. It automatically self-centers on the thumb depressor for immediate use.

Q4: Does it affect how the syringe feels in my hand?

No — by design. The Control Ring preserves your syringe’s native ergonomics, weight balance, and tactile feedback while adding intuitive one-handed aspiration support.

Q5: What if my syringe designs change in the future?

KA Design's Control Ring Collection is built to evolve alongside injectors. We monitor syringe platform changes continuously and develop updated Control Rings to ensure continuity, precision, and future-proof performance.

Q6: What are Control Rings made of?

Control Rings are made from a premium PLA-based polymer, chosen for its high strength-to-weight ratio and durability. Every element has been distilled to the essentials — eliminating unnecessary bulk or weight — to deliver unwavering stability, balance, and precision in the injector’s hand.

Q7: Where are your products made?

Every Control Ring is designed, engineered, and produced in the United States.
