Placement of intra-articular injection
verified by the backflow technique.
When needle tip position is confirmed by aspiration, treatment efficacy significantly improves
Successful treatment
Assists in verifying correct position through aspiration
Reduces exposure of hub to air and handling
Enables practitioners to be fully engaged and focused on procedures
Provides improved workflow and equipment accountability
Failed treatment
20% of injections miss the correct site, failing to deliver medication and failing to provide pain relief.

What Physicians Say
It makes a cumbersome procedure easier for both the practitioner and the patient.
Dr. Michael Wilmink, MD Orthopedic Surgeon
The A-Tap™ makes the injection procedure cleaner compared to standard care where needle hub is exposed and fluid may leak, especially when switching syringes is common.
Dr. Delwyn Worthington, MD Orthopedic Surgeon
Likely to do more aspirations with this device to remove fluid and increase drug concentration, improving efficiency of injection.
