NerveGuard NRFit is a disposable injection pressure monitor and limiter used during peripheral nerve blocks. It connects between a compatible nerve-block needle and the injection syringe, allowing pressure to be monitored as anaesthetic is injected.
The device uses a valve and locking mechanism that respond to the force applied at the syringe. When the pressure limit is exceeded, the mechanism closes the valve and stops flow. Releasing pressure allows the valve to reopen so the procedure can continue.

Connections and Pressure Limit
The NRFit version uses standardized NRFit connectors for the syringe and needle connections. The pressure-limiting threshold is 15 psi with a tolerance of plus three psi, giving a maximum of 18 psi.
