US-based medical technology firm Halyard Health has launched a new peripheral nerve locator and stimulator called EZstim III, expanding its line of ON-Q Pain Relief System products.

Designed to monitor the effects of muscle relaxant drugs during general anesthesia and improve the efficacy of catheter placement during continuous peripheral nerve blocks (CPNBs) for acute pain, the device acts a full-function nerve locator and a neuromuscular block monitor.

EZstim III is equipped with an audible indicator of open circuit or high-resistance condition along  with detachable, function-specific lead sets to protect against inappropriate use, and a built-in bumper to prevent breakage.

"Use of the ON-Q System can help avoid risks associated with opioid use."

Halyard Health acute pain general manager Roger Massengale said: "The EZstim III is an important addition to our ON-Q Pain Relief System as we look to provide a full spectrum of solutions for acute post-surgical pain.

"The addition of EZstim III to our product portfolio gives clinicians one more tool to help them provide patients with the best care possible.

"Use of the ON-Q System can help avoid risks associated with opioid use."

The device includes a LCD screen, which is claimed to be bright and easy to read as well as continuously displays entire instrument settings and battery life.

Compatible with electrosurgery, EZstim III enables operation near other surgical equipment.

ON-Q Pain Relief System range of products include pain pumps, pump accessories, peripheral nerve block accessories, in addition to a training, education and support system.
