Description
The Department of Veterans Affairs (VA) is seeking information from potential sources for the TwitchView 2 Monitor System and accessories. The system will be used to assess the degree of neuromuscular blockade/muscle relaxation in patients during surgery. The requirement is for a brand name or equal product, and the VA is encouraging the submission of pricing, capabilities, and other market information. The system must meet specific salient characteristics, including the use of electromyography (EMG) technology, objective measurement of neuromuscular blockade and recovery, and support for Train-of-Four (TOF) and Post-Tetanic Count (PTC) monitoring.
Some key features of the required system include:
• Quantitative neuromuscular transmission monitoring system using EMG technology
• Objective measurement of neuromuscular blockade and recovery
• Support for TOF and PTC monitoring
• Real-time waveform display and numerical neuromuscular parameters
• Device must use EMG waveform analysis with noise-cancellation technology
• Must provide performance validated against mechanomyography (MMG) or equivalent clinical gold standard
• Must reliably identify TOFR ≥ 0.90 to confirm adequate recovery
• Must be designed for operating-room environments with ruggedized housing
• Must include durable patient cable rated for ≥5,000 use cycles
• System must include a sterile, single-use electrode per patient
• System must include a universal OR mounting arm compatible with common anesthesia machine rails or equipment poles
