TofScan NMT monitor
The TofScan is a Train-of-Four monitor which enables objective monitoring of the neuromuscular junction using Acceleromyography (AMG). This widespread technique provides a reliable measurement of evoked muscle responses. The operator can obtain objective measurements for the main stimuli used. Its three-dimensional accelerometer allows a complete and accurate measurement of thumb movements while avoiding the necessity for sensor calibration.

The sensor is ergonomically designed for intuitive and optimal positioning throughout the monitoring period. This factor, whilst providing reliable measurements also facilitates the task of setting up the sensor. 

In spite of the inherent technology, the TofScan is a simple device to use. Since the device operates on batteries as well as with the AC power supply it can be set up without the need for a power cable and easily moved into place. Its fixing clamp allows optimal positioning on a standing pole and reduces the risk of breakage.

The screen shape and single button selection have been designed with simplicity and ergonomics in mind. And although the TofScan enables a simple and objective monitoring of the neuromuscular junction, it is designed as an operational medical device to be tough, reliable and practical.
