Evaluation: Mindray BeneVision TM70 Integrated-Display Telemetry System

September 21, 2022 | Evaluations & Guidance


  • The Benevision TM70 is used to monitor patients who are at risk for cardiac events but not acutely ill enough to warrant continuous bedside monitoring. It also offers additional measurements that can be used to monitor conditions like hypoxia and compromised respiratory status.
  • Major components and software features:
    • BeneVision TM70 Telemetry Monitor (telemetry transmitter): The patient-worn telemetry transmitter is used to acquire patient data and relay it wirelessly over the 608-614 MHz, 1395-1400 MHz, or 1427-1432 MHz wireless medical telemetry service (WMTS) band. The TM70 telemetry monitor is intended for use on adult and pediatric patients over three years old to monitor ECG, pulse oximetry (SpO2), noninvasive blood pressure (NIBP), and respiration physiologic data. The TM70 can operate in traditional Telemetry mode with alarms at a central monitoring location; and/or as a wireless patient monitor with alarms locally and at the central monitoring location; or as a wireless module communicating data to the BeneVision N-Series patient monitors.
      • The physiologic data can be analyzed, alarmed, stored, and reviewed locally on the display of the monitor.
      • The transmitter is powered interchangeably by either a rechargeable Li-ion battery or three AA alkaline batteries and is equipped with a 3.5-inch color touchscreen LCD.
        • Size: 126 × 64 × 23 mm (5 × 2.5 × 0.9 in)
        • Weight: 230 g (8.1 oz) (with batteries)
        • Claimed battery life (with 3 AA batteries): ≥36 hours (5-lead ECG); ≥28 hours (5-lead ECG + SpO2)
      • The transmitter is also equipped with software to analyze the ECG and detect high-priority arrhythmias, and it can operate offline as a mini-monitor when communication is lost between the transmitter and the Distributed Monitoring System (DMS) server.
      • Parameters supported:
        • 3/5/6-lead ECG
        • SpO2 (through Masimo and Nellcor modules)
        • Impedance respiration
        • ST/25 Arrhythmia + AFib/QT
        • NIBP via BP10 module
      • The bedside monitor can receive information from the telemetry transmitter in two ways:
        • Remote view: The TM70 can be connected with all Mindray bedside patient monitors for remote view of information. Alarms from the telemetry transmitter can be annunciated at one or multiple remote bedside monitor(s).
        • Pairing: Each telemetry transmitter can be associated with an individual BeneVision N-Series bedside monitor. After the transmitter is paired with the monitor, the measurement data from the transmitter can be viewed on the monitor's screen. All data between the N-Series monitor and telemetry transmitter is merged together into a single data stream for the patient.
    • The BeneVision DMS, which consists of two primary components:
      • BeneVision DMS Servers, which centrally store and manage communications to the patient monitoring devices
      • BeneVision DMS WorkStations, which allow access to the data. The BeneVision DMS WorkStation allows a centralized view of up to 32 patients on one to three screens and is intended to enable viewing of patient information collected from the bedside monitors and telemetry transmitters (this information is stored on the BeneVision DMS Server). The BeneVision DMS WorkStation is used to:
        • Admit and discharge patients via an automatically populated list from the hospital's admit/discharge/transfer (ADT) system by using a bar-code scanner or through a patient search feature
        • View near-real-time numeric data, alarm history, full-disclosure waveforms, graphical and tabular trends, and 12-lead and ST analysis
        • Serve as a secondary source of audible and visual alarm signals
        • View alarm history, discharged patient list, and full-disclosure waveforms
