What is the difference between the EPD and E-EPD?

What is the difference between the EPD and E-EPD? featured image

Rethink patient safety with PHS Medical's patented Epidural Positioning Device and Electric Epidural Positioning Device. The EPD and E-EPD feature unique torso positioning for proper cervical alignment to position patients safely and comfortably during epidural procedures.

Patented in 2001, the Epidural Positioning Device is a landmark device designed by an anesthesiologist that positions patients correctly and comfortably by encouraging cervical, thoracic and lumbar flexion while maintaining a solid and stable position. Adjustable chest, arm and head support ensures that patients of every body type and size can be accommodated and the spine remains immobile during epidural placement. 

To better understand the EPD and E-EPD, we've outlined the main similarities and differences between them.

Correct Positioning

Both the EPD and E-EPD are designed to encourage cervical, thoracic and lumbar flexion while maintaining a solid and stable position. Proper positioning reduces safety and positioning concerns and helps the anesthesiologist perform a successful block.

Supports Various Patient Sizes

The height range of both devices is 50" - 60" and they can safely accommodate different sized tables/beds and patients. With a sturdy load capacity of 600 pounds, patients of various sizes can be securely supported by the EPD and E-EPD.

Where It's Used

They are both predominantly used in labor & delivery suites and surgical departments, but they’re also beneficial in pain management clinics. Anywhere epidural or spinal anesthesia is administered while the patient is seated, the EPD or E-EPD can be utilized. In addition, some hospitals use them for Thoracentesis procedures.

Easy to Move & Lock

Both the EPD and E-EPD have a medical grade profile locking caster system designed for easy transport and stability.




The main difference between the EPD and E-EPD is how you adjust them. An electronic hand control adjusts the E-EPD to the correct height and foot position for each patient and easy-to-operate mechanical lock and release systems adjust the chest, arm and head pieces. On the EPD, manual controls easily adjust the height, foot, chest, arm and head supports.
