We created the DRX9000™ True Non-Surgical Spinal Decompression™ System to assist healthcare providers in their effort to treat low back (lumbar) pain.
The DRX9500™ Cervical Device provides patients a program of treatments for relief from disc related neck pain.
The DRX9000™ Combination System provides a program of treatments for pain relief for those patients suffering with chronic low back or neck pain.
The pictures on the Axiom Worldwide website of the DRX family of products are depicted with both a hood and no hood to illustrate the variations depending on space requirements.
Nested Closed-Loop Feedback
The entire DRX line of products feature closed-loop feedback which is defined as an automatic control system that can adjust and self-correct its operation according to differences between the actual and desired output. closed-loop feedback systems improve overall system performance.
The effectiveness of closed-loop feedback systems varies based on the variables measured, how they’re measured, and how often they’re measured. With respect to spinal decompression systems, the measured variable is most often force, which is the amount of tension used to distract the spine.
The DRX™ device series incorporates closed-loop feedback within a closed-loop feedback system, referred to as nested closed-loop feedback. As illustrated above, one of the three stops on the closed-loop feedback path in the DRX™ devices is the servo-amplifier and servo-motor. The servo-amplifier receives corrective force commands from the treatment computer 13 x per second. The servo-motor itself contains very accurate devices that measure force, speed, and power consumption. The servo-amplifier monitors these variables, correcting the actions of the servo-motor 4,000 times per second. The nested closed-loop feedback system is one of the technological hallmarks of the DRX™ device series.
