Zoncare U90 Classic 12-Channel EKG Machine

The Zoncare U90 Classic is a 12-channel resting electrocardiograph built for clinical ECG acquisition in hospitals, clinics, and diagnostic centers, combining a 9.7-inch tilted touchscreen with 12-lead synchronous acquisition, 32,000 Hz sampling, and DICOM-based network connectivity. It is positioned as a classic, workflow-oriented platform that pairs a large grid-background display with a multi-axis TP® thermal printer and Wi-Fi/LAN integration—allowing ECG reports to be transmitted directly to hospital PACS, HIS, and EMR systems without a dedicated workstation.

The U90 Classic supports simultaneous 12-lead acquisition and display across multiple acquisition modes (pre-sampling, real-time, triggered, and period sampling) and single-chamber or dual-chamber pacemaker detection. The system incorporates iFilter™ adaptive filtering to improve ECG signal quality, and a waveform freezing and review function that allows clinicians to select any segment for analysis and printing. A report preview function supports signal quality confirmation before printing, and the system supports reanalysis based on modified patient information—useful when patient demographics are corrected after acquisition.

The U90 Classic supports manual and automatic print layouts including 3×4, 3×4+1, 6×2, 6×2+1, 6×2+3, and 12×1, with 12-channel simultaneous printing without distortion. Storage formats include ZQECG, PDF, PNG, XML, HL7, DICOM, and GDT, and reports can be transmitted via DICOM, HTTP, FTP, and SAMBA protocols to hospital information systems. The system includes USB, RJ45, and SD card ports for peripherals and data export.

Regulatory status: The U90 Classic is described in Zoncare documentation as supporting DICOM connectivity for PACS integration, and the platform is referenced in distributor documentation with CE and ISO certification. No FDA 510(k) clearance specific to the U90 Classic model name was identified in the public FDA database during preparation of this page; a 2022 FDA import alert referencing Wuhan Zoncare cited failure to list under 510(j) or provide 510(k) notification for an ECG device, and the specific model and current status should be confirmed directly with Zoncare before U.S. purchase. No independent peer-reviewed clinical validation study specific to the U90 Classic was identified in the public literature during preparation of this page. Availability, labeling, and cleared claims vary by market.

Key Features & Benefits

9.7-Inch Tilted Touchscreen with Grid Background

The U90 Classic features a 9.7-inch tilted touchscreen with a grid background, supporting direct on-screen interaction for waveform review and menu navigation. The grid-background display is designed to support standard ECG paper-format visualization on screen, and the tilted design supports ergonomic viewing from different scanning positions. The display is paired with a QWERTY alphanumeric keyboard and carry handle for efficient patient information entry and transport.

12-Lead Synchronous Acquisition with 32,000 Hz Sampling

The system acquires and displays all 12 leads simultaneously across multiple acquisition modes—including pre-sampling, real-time, triggered, and period sampling. The 32,000 Hz sampling rate and 24-bit A/D conversion are paired with a 0.01–350 Hz ultra-wide frequency response, positioned to acquire signals from pediatric through elderly patients. A high-performance chip module supports more accurate ECG signal collection, and iFilter™ adaptive filtering is designed to improve signal quality.

Pacemaker Detection and Waveform Review Tools

Single-chamber and dual-chamber pacemaker detection is supported for patients with implanted devices. Waveform freezing and review functions allow the clinician to select any waveform segment for analysis and printing, and report preview supports signal quality confirmation before printing. Reanalysis based on modified patient information supports workflow adjustments when patient demographics are corrected after acquisition.

DICOM Connectivity for PACS, HIS, and EMR Integration

The U90 Classic supports Wi-Fi and LAN connectivity, with DICOM, HTTP, FTP, and SAMBA protocols for direct transmission of reports to hospital PACS, HIS, and EMR systems without a dedicated ECG workstation. Report formats include PNG, DCM, XML, HL7, PDF, JPG, GDT, and ZQECG. DICOM connectivity is positioned to minimize manual transcription errors and delays compared with manual data migration.

Multi-Axis TP® Thermal Printer with Flexible Layouts

The U90 Classic includes a multi-axis TP® thermal printer designed for stable printing regardless of paper movement conditions, with manual and automatic layouts including 3×4, 3×4+1, 6×2, 6×2+1, 6×2+3, and 12×1. 12-channel simultaneous printing without distortion is supported, and an external printer is also supported for additional workflow flexibility. Paper size is 210 × 140 mm.

Comprehensive Peripheral and Data Export Support

The U90 Classic supports USB, SD card, scanner, laser printer, card reader, projector, and external keyboard and mouse through its peripheral ports. Storage formats include ZQECG, PDF, PNG, XML, HL7, DICOM, and GDT, and the system includes USB, RJ45, and SD card ports for data export. Rechargeable battery operation supports approximately 2 hours of backup time, and defibrillation protection is included.

Classic Clinical Workflow Design

The U90 Classic is positioned as a classic 12-channel resting ECG platform with an easy-to-use interface, bright color display, and touch operation. The carry handle supports hand-carried transport between examination rooms and bedside locations, and the QWERTY keyboard supports efficient patient information entry.
