Vital Diagnostics · Model Envoy 500
Touch Screen The Envoy 500 has a built-in LCD touch screen and, is driven by the Windows 2000 operating system. This provides greater ease of use and space savings by eliminating a bulky external monitor and CPU. Quality Control Quality Control results are stored in memory and easily displayed on the screen. QC can be evaluated using up to six Westgard rules and displayed with either Levey-Jennings Graphs or Juden Plots. Pre-Programmed Parameters The Envoy Reagent application parameters are pre-loaded into the software, saving users time and eliminating the possibility of data entry mistakes. Large Capacity The Envoy 500 holds up to 40 individual Envoy reagents (mono or dual), providing a longer walk-away operation Refrigerated Reagent Tray Onboard refrigeration and storage assures reagent stability, which increases reliability of results, while lowering laboratory costs. Continuous Inventory Monitoring Continuous inventory monitoring enables the operator to know the number of tests remaining for each reagent, minimizing waste. Positive Reagent Identification The reagent chamber contains an infrared barcode scanner capable of scanning Envoy bar coded reagents, automatically recognizing reagent position and lot expiration intervals Sample Wheel The Envoy 500 sample wheel has 52 positions available for patient samples and 26 for calibrators and controls providing the laboratory high throughput capability. Primary tubes or sample cups can be used, providing the testing flexibility users need. Liquid Sensor Detection Liquid sensor detection prevents reporting of invalid results from an insufficient sample. This ensures accurate results and proper treatment decisions. Positive Sample Identification The sample chamber contains an infared barcode scanner, capable of scanning patient barcodes eliminating the need to manually enter patient information and reducing the risk of sample errors that can cost users time and money.
