3.2 Running a Test: Step-by-Step Guide
Running a test on the Hemochron Signature Elite involves a straightforward process. Begin by inserting the cuvette into the test chamber, ensuring it clicks into place. Next, add the appropriate amount of blood or plasma to the cuvette using a syringe or pipette. Close the chamber and press the “Start” button to initiate the test. The device will automatically detect the sample and begin analyzing coagulation parameters. Once complete, the results will be displayed on the screen. For multiple tests, repeat the process with new cuvettes. Always follow proper biohazard disposal protocols for used materials. If an error message appears, refer to the troubleshooting section for resolution. This step-by-step approach ensures accurate and efficient coagulation testing in point-of-care settings.
Quality Control and Assurance
The Hemochron Signature Elite requires daily quality control tests using normal and abnormal levels to ensure accurate results. Automatic checks occur every 8 hours, and manual QC can be performed for additional verification.
4.1 Daily Quality Control Tests and Procedures
Performing daily quality control (QC) is essential for ensuring the accuracy and reliability of the Hemochron Signature Elite system. The device automatically checks its functionality every 8 hours, but manual QC tests are also recommended. These tests involve using normal and abnormal liquid QC controls to verify the system’s performance. The normal control ensures the system is functioning correctly, while the abnormal control checks for potential issues that may affect test results. Additionally, external quality control (EQC) can be performed manually by pressing the QC button followed by the 1 key. This process records the results in the QC database for future reference. Regular QC testing helps maintain compliance with clinical standards and ensures precise coagulation monitoring in point-of-care settings. Always refer to the manual for detailed instructions on executing these procedures effectively.
Maintenance and Troubleshooting
The Hemochron Signature Elite requires routine maintenance, including cleaning and replacing parts as needed. Troubleshooting common issues is simplified with error codes and solutions detailed in the manual.
5.1 Common Issues and Solutions
The Hemochron Signature Elite manual addresses common issues users may encounter during operation. One frequent problem is error codes such as “Out of Range-Hi,” which often indicates contamination or incorrect cuvette usage. To resolve this, ensure proper sample preparation and verify cuvette compatibility. Another issue is battery-related errors, which can be fixed by charging the device or replacing the battery pack. Display malfunctions, such as frozen screens, can be resolved by restarting the system or updating its software. Additionally, manual EQC (electronic quality control) can be performed by pressing the QC button followed by the 1 key, allowing results to be stored in the QC database. Regular maintenance, including cleaning and replacing worn parts, helps prevent these issues. The manual provides detailed troubleshooting steps and solutions to ensure optimal performance and accurate test results.
