Stimpod NMS450

The STIMPOD NMS450 is a nerve stimulator that provides dual functionality with both precision nerve location (Nerve Locating and Nerve Mapping) and Neuromuscular Blocking Agent (NMBA) monitoring. Localization of nerves by electrical stimulation involves connecting the nerve stimulator to a conducting needle through which local anesthetics can be injected. The distance of the needle (cathode) from the nerve can be estimated by establishing the minimum threshold current required, facilitating a neuromuscular response. Neuromuscular Blocking Agent (NMBA) monitoring is provided through percutaneous nerve stimulation using Train-of-Four (TOF), Double Burst (DB) or Post-Tetanic-Count (PTC) stimulation. The TOF and DB ratios and the PTC counts are monitored independently using a three dimensional accelerometer.

Features

High Current Range:
An 0-80mA current range for the NMBA mode ensure effective nerve membrane depolarization

Separate Driving Circuits:
A maximum of 100V is generated for the locating mode for subcutaneous stimulation. A maximum of 400V is only generated for the Mapping/NMBA modes for percutaneous stimulation. 

Nerve Mapping Probe:
A Nerve Mapping Probe designed for percutaneous nerve mapping with a maximum current of 20mA ensuring proper nerve membrane depolarization

Combined Nerve Mapping/Locating:
Auto sensing cable enables the anesthesiologist to combine nerve mapping and nerve locating for quick and precise nerve location     

Charge Transfer Waveform: 
Display real time feedback of the actual delivered stimulus 

Proximity Indicator:
Visual and audible feedback is given when the target current- and pulse width ranges are reached indicating probable nerve proximity 

Non-Linear Adjustment:
Choose between Linear (normal) and Non-Linear progression of current and pulse width settings - Non–Linear mode allows the user to customize 20 current and pulse-width setting positions
