Description
VueSign BES1207 Nano Handheld 12-Lead ECG Machine is a professional, ultra-compact digital electrocardiograph developed and manufactured by BMV MEDTECH GROUP CO., LTD, a global leading medical device enterprise. Marketed as the smallest and most exquisite handheld vital sign monitor for clinical cardiac care, this upgraded device integrates high-precision 12-lead ECG signal acquisition, an intuitive 7-inch touchscreen operation interface, comprehensive arrhythmia analysis, robust medical-grade safety protection, and industry-leading flexible dual printing solutions – the most in-demand feature for clinical users. It delivers a reliable, portable, and user-friendly cardiac diagnostic solution for hospitals, clinics, emergency departments, primary care facilities, physical examination centers, and home health care services worldwide.
At the core of the BES1207 Nano is its industry-leading 12-lead ECG acquisition system, which supports both Standard and Cabrera lead systems, with simultaneous acquisition of all 12 leads to capture complete cardiac electrical activity in a single test. With an ultra-high sampling rate of 8000 samples per second, an input dynamic range of ±500mV, and a frequency response of 0.05-150Hz (-3dB), the device captures even the most subtle cardiac waveform abnormalities with exceptional precision, ensuring accurate diagnosis of cardiac conditions. The input circuit adopts a floating design with full defibrillation and pace-making protection, eliminating signal interference from high-voltage medical equipment and ensuring safe use in operating rooms, emergency resuscitation, and critical care settings.
The device features a high-definition 7-inch 800×480 touchscreen LCD display, which presents real-time ECG waveforms, operating conditions, time, and heart rate in a clear, intuitive clinical layout. The integrated touchscreen keyboard supports full input of patient information including name, age, sex, and hospital name, streamlining clinical record-keeping and standardized report generation. With an IEC Class IIa, Type CF safety classification, the device meets the strictest international medical device safety standards: patient current leakage is less than 10uA, input circuit current is ≤0.1μA, and input impedance is ≥50Mohm, ensuring maximum safety for patients during testing. A CMRR (Common Mode Rejection Ratio) of >100dB (with AC filter) effectively eliminates common-mode signal interference, delivering clear, noise-free ECG waveforms even in busy clinical environments with complex electrical interference.
Upgraded Dual Printing Solutions (Core User-Focused Feature)
To address the most critical clinical demand for flexible, convenient ECG report output and archiving, the upgraded BES1207 Nano offers two customizable printing versions, adapting to diverse clinical workflows and facility setups:
- Wireless Printer Direct Connection VersionThis version supports seamless pairing with compatible wireless thermal printers via built-in wireless connectivity, enabling one-click on-site printing of standardized ECG reports with professional interpretation directly from the handheld device. No computer or complex wiring is required, making it ideal for point-of-care testing, emergency departments, community health screenings, pre-hospital emergency care, and bedside testing in wards. It eliminates the need to transfer data to a separate device for printing, drastically reducing report generation time and streamlining busy clinical workflows.
- ECG Collector & PC Connected Printing VersionThis version enables the BES1207 Nano to function as a professional high-precision ECG signal collector, with seamless USB connection to a hospital or clinic’s computer system. Clinicians can transfer raw ECG data and pre-generated reports to a PC in real time, for advanced waveform analysis, report editing, standardized printing, and long-term electronic medical record archiving. This version is perfectly adapted to in-hospital clinical workflows, where ECG data needs to be integrated into the hospital’s HIS/LIS system, shared for remote consultation, or archived for long-term patient follow-up.
To meet diverse clinical diagnostic needs, the BES1207 Nano offers multiple flexible operation modes: fully automatic mode for one-click standardized testing, manual mode for customized parameter adjustment, single-channel 60s compressed record mode for long-term waveform monitoring, and dedicated arrhythmia analysis mode with R-R histogram and trend chart display for in-depth cardiac rhythm evaluation. A built-in multi-stage digital filter system eliminates common clinical signal artifacts: AC filter (50Hz or 60Hz, -20dB) suppresses power line interference, EMG filter (25Hz/35Hz/45Hz/75Hz/100Hz, -3dB) eliminates muscle tremor artifacts, and drift filter (0.5Hz, -3dB) corrects baseline drift. The device also supports image freeze functionality, allowing clinicians to review, zoom, and capture critical ECG segments for detailed analysis and printing.
For streamlined clinical data management, the BES1207 Nano has built-in memory that can store up to 200 ECG reports in PNG format, with full support for report presentation, review, and re-printing, complete with automated ECG interpretation. It can be connected to a PC via USB interface for seamless data transfer, electronic medical record archiving, and remote teleconsultation. A real-time lead-off detection indicator alerts clinicians to poor lead connection immediately, preventing invalid tests and reducing repeated operations for both clinicians and patients.
Designed for both fixed clinical use and mobile care scenarios, the device is powered by a built-in 4000mAh rechargeable 18650 lithium battery, with AC power support (220V±10%, 50Hz±2%, 75VA) for continuous 24/7 use in clinical settings. Its ultra-compact, lightweight handheld design enables easy portability for pre-hospital emergency care, community health screenings, home visits, and bedside care in ICU wards. The device is fitted with a standard 10-core patient ECG cable, with a 2Φ5x20mm 3.15A 250V fuse for overcurrent protection, ensuring long-term reliable operation in demanding clinical environments.
Widely applicable across routine cardiac health screening, pre-anesthesia cardiac assessment, cardiovascular disease diagnosis, emergency critical care monitoring, geriatric regular check-ups, community health screenings, and home cardiac monitoring, the upgraded BES1207 Nano with dual printing solutions is an indispensable core device for modern clinical cardiac care, empowering medical professionals to deliver fast, accurate, and safe cardiac diagnosis for every patient.
