Dose Calibrator with Integrated Printer for Hot Cell Dose Records

Product Introduction

The Dose Calibrator with Integrated Printer addresses the documentation burden in nuclear medicine dose preparation. For every dose administered, departments must maintain a record of the measured activity, patient identifier, radiopharmaceutical, date, time, and technologist. Traditional paper-based recording is time-consuming and error-prone; manual transcription errors can lead to incorrect billing, regulatory violations, or patient safety issues. This instrument includes a built-in thermal printer that produces a label or paper record with each measurement, eliminating manual transcription. The printer is integrated into the remote display unit, positioned outside the hot cell for easy access. The user can configure the print format to match departmental requirements, including barcodes for automated data entry.

Application Range

The Dose Calibrator with Integrated Printer is designed for any nuclear medicine department that needs efficient, error-free dose documentation. Primary applications include recording patient-specific dose measurements, documenting generator eluate activity for quality control, producing records for regulatory inspection, creating labels for dose vials or syringes, logging waste characterization measurements, and documenting linearity testing and constancy check results. The instrument is particularly valuable for high-volume departments where manual documentation is a significant time burden and for departments that have experienced documentation-related errors.

Performance and Benefits

The Dose Calibrator with Integrated Printer reduces documentation time by 50–75% compared to manual recording and eliminates transcription errors entirely. When a measurement is complete, the user presses the "Print" button (or optionally, the instrument prints automatically). The thermal printer produces a label or paper record containing: measured activity (mCi or MBq), isotope, date, time, user ID (entered at login), sample description (vial/syringe/capsule/geometry), and a unique measurement ID. The user can configure the print format through the instrument's software: options include 1" x 2" labels for syringe shields, 2" x 4" labels for vial shields, or 3" wide paper tape for logbooks. Barcode printing is supported, with the barcode encoding the measurement ID and measured activity. The printer uses direct thermal printing — no ink or toner required — and the paper is resistant to fading from light, heat, and chemicals (archival-grade). The printer paper is loaded from a cassette that holds a full roll (approximately 500 labels or 50 feet of tape), and a low-paper alert notifies the user when replacement is needed. The printer mechanism is sealed against contamination and can be decontaminated by wiping. The instrument integrates the printer with the data logging system. Each printed record is also stored in the internal database, so if a label is lost or damaged, the record can be reprinted from memory. The database stores up to 1,000 measurements, and the user can search by measurement ID, date, isotope, or user ID to retrieve and reprint specific records. For departments using laboratory information systems (LIS), the instrument can be configured to print barcoded labels that the LIS can scan for automated data entry. Alternatively, the USB port can export measurement data directly to the LIS, with the printer used only for backup documentation. The printer also supports quality control documentation. When the user performs a constancy check, linearity test, or other QC procedure, the instrument can produce a printed report showing the results, acceptance criteria, and pass/fail determination. These reports can be filed directly in the QC logbook, eliminating manual transcription of QC results. For nuclear medicine departments, the primary benefit of the integrated printer is reduced documentation errors. Manual transcription errors — misreading a display, transposing digits, forgetting to record the isotope — are a common source of dose record problems. The printer eliminates these errors by recording the exact measurement displayed by the instrument. The printer also saves time: instead of writing down each measurement, the technologist simply prints the label and attaches it to the dose record. For high-volume departments, this time saving can amount to an hour or more per week. For departments subject to regulatory inspection, the printed records provide clear, legible documentation that is easy for inspectors to review. The Dose Calibrator with Integrated Printer transforms dose documentation from a manual chore into an automated, error-free process.
