Patented Safety Design

The A.N.D. device's automatic locking mechanism is a patented safety feature. Upon reaching the maximum safe capacity (approximately 200± needles for standard size, 750± needles for large size), the mechanism automatically locks in the down position making it impossible to automatically accept additional needles. The unit may not appear to be full because a safety zone (see diagram) is incorporated into the device to prevent overfilling, keeping used needles safely away from the user.
