Chapter 1: Installation and Setup Principle of Operation and Intended Use The Sonoclot Coagulation Analyzer calculates onset of clot formation and clot rate for in vitro coagulation studies by monitoring mechanical changes that occur in blood samples during hemostasis. The mechanism is a tubular probe that moves up and down within a blood sample. As the sample progresses through various stages of clotting, the electronic circuitry detects increasing resistance. This produces a series of electronic signals that are processed by a microcomputer. Results are reported on the LCD display panel.

Chapter 1: Installation and Setup

Good Operating Procedures (applicable for all tests) The quality of test results depends on proper technique. Carefully follow these precautions: 1) Operator should read this operator’s manual in its entirely before attempting to operate the analyzer. 2) Only properly trained lab personnel and healthcare professionals should operate the analyzer. 3) Diagnosis should be based on test results in combination with clinical observations. 4) Handle materials with care: • When taking a blood sample, avoid heparin contamination from catheters. • Never use the first sample from a new line to avoid sample contamination with tissue thromboplastin. • Keep blood, dirt, and other substances away from the probe mount hub to avoid contaminating the electromechanical transducer. • Never reuse a probe or cuvette to prevent thrombin contamination. 5) For consistent results, the cuvettes should be warmed prior to analysis. To warm, place the cuvette in its holder at least 30 seconds prior to running a test. 6) Always insert and remove the probe by moving it vertically over the probe mount hub. Never move the hub horizontally. Make sure the probe is fully seated to avoid interference with the stir-bar. 7) Always remove the cap from the cuvette prior to placing it into the cuvette holder. Failure to do so can damage the transducer. 8) The cuvette must be fully seated in the cuvette holder to avoid interference between the probe and stir-bar. 9) Do not overfill the cuvette. The proper fill level is slightly below the inner rim of the cuvette. 10) Native whole blood must be analyzed within 2 minutes or less of collection. 11) Perform QC testing to verify proper operation of the analyzer and activation cuvettes. See page 1-6. 12) Use proper biohazard handling techniques to dispose of probes and cuvettes. 13) On rare occasions, mechanical disturbances may cause incorrect results. Always inspect results to ensure that they are consistent. 14) High viscosity blood samples (immersion response > 25 clot signal units as displayed on the instrument) can stratify. Use an external device to mix the blood sample before placing it in the cuvette.

Warnings, Cautions, and Hazards 1) WARNING: As with any laboratory test result, diagnosis should not be based solely on the analyzer test results. The attending physician is responsible for interpreting the analyzer test results in conjunction with the patient’s condition, other test results, and clinical observations. 2) WARNING: To safeguard against electrical shock, only use a grounded electrical outlet. 3) WARNING: Use only as specified by Sienco, Inc. Otherwise, equipment protection may be impaired. 4) CAUTION: Only properly trained laboratory personnel and/or other appropriate health care professionals should use the analyzer. 5) CAUTION: A biomedical engineering department should check the analyzer at least once a year for compliance with leakage standards. 6) HAZARD: Human blood is a biohazardous material. The operator should wear appropriate protective gear when handling blood and/or test cuvettes containing blood samples. Biocontaminated materials should be handled and disposed of properly in accordance with hospital, local, state, and federal regulations. 7) CAUTION: Do not place the analyzer on counter tops where other vibrating instruments, such as centrifuges, are located. Mechanical vibration may cause erratic results.

Quality Control Proper performance requires regular quality control (QC) tests: 1) Daily, run a reference viscosity test for the analyzer. This requires QC kit 900-1303. 2) Monthly, and prior to the use of a new shipment, validate the activated cuvettes. This requires QC kit 900-1318. Complete instructions for running each QC test are included in the kits. The kits also include forms for recording QC results. To order quality control kits, contact Sienco at 800-432-1624 or contact your distributor.

Cuvette and Probe Setup 1) Open the head by tilting it backwards. The display will read “Open.”

2) Sharply tap the cuvette on a hard surface to dislodge activation powder from the sides and lid. 3) With a slight twisting motion, use the cuvette to seat the probe on the mount hub. This motion should result in the probe sliding straight over the probe mount hub. The hub should not move sideways. The probe must be fully seated for proper operation.

4) Remove the cuvette, leaving the probe on the hub.

5) Remove the lid from the cuvette by placing it in a convenience well and popping the lid off with your thumb.

Chapter 2: Running a Whole Blood Sample

6) Insert the cuvette into the cuvette holder. Make sure it is fully seated. Close the head. Allow the cuvette to warm in the cuvette holder for at least 30 seconds. DO NOT close the head on a lidded cuvette. It will damage the instrument. Different tests have different set-up requirements. Please refer to the product insert for detailed instructions.

Obtaining the Blood Sample Native whole blood must be analyzed within 2 minutes of collection. When drawing blood, observe the following precautions: 1) Carefully decide where to draw the sample. Contamination (from a heparinized line, a heparin-impregnated catheter, or a surgery prep line) will cause inaccurate results. 2) Withdraw blood in a smooth, slow, and non-traumatic manner. Do not use force. 3) When drawing from an anesthesia or pump port, use a 2-syringe technique. Discard the first syringe of 2 to 3 ml. Use the second syringe for the sample. You MUST use plastic syringes to avoid uncontrolled glass activation.

Running the Analyzer 1) Transfer the whole blood sample from the syringe into the warmed cuvette. Use a blunt cannula tip for a clean and controlled fill. Fill the warmed cuvette with the blood sample until the fluid level is slightly below the inner rim of the cuvette. This volume is approximately 330 to 360 µl. Fill slightly below here

2) Leaving the head open, immediately press the START/STOP button. 3) The magnetic stirrer will rotate and the display will read: 4) When mixing is completed, the analyzer will beep and the display will read: “Close Head.”

5) Close the analyzer head. Make sure it is fully seated over the head alignment pin.

6) During data collection, the LCD display will show the test being run, the clot signal reading (CS), the time in seconds, and “???” for each result. When the analyzer is calculating a result, the display will flash the number the result is greater than.

g bAC T 13 11 AC T=???? CR=???

7) The sample is initially a liquid. After several minutes the sample begins to evolve into a clot. The analyzer detects this initial clot formation and calculates the time the sample remained a liquid (ACT). During the next several minutes of analysis, the fibrinogen converts into a fibrin gel. The analyzer calculates the rate of change in the clot signal (Clot Rate). 8) When a result has been calculated, the analyzer g bAC T will beep and display the time that the sample remained a liquid (ACT) and the Clot Rate (CR),. AC T= 177 CR= 19 Times for results vary from 2 to 20 minutes depending on heparin levels and clinical conditions. The numeric result is displayed next to the corresponding text for the appropriate channel. “NR” is displayed if no results were found for the test sample. 9) The analyzer will automatically stop data collection when results for ACT and Clot Rate have been calculated or after 30 minutes. 10) Open the head and remove the probe from the hub with a probe extractor. Avoid moving the hub sideways. Propery discard the probe and the cuvette. Lower the head assebly to maintain temperature control of the instrument.

Chapter 3: Maintenance and Troubleshooting Maintenance Cleaning Clean after use to reduce biohazard risks. The analyzer can be sprayed or wiped with a disinfectant approved by your institution. Close the heads when spraying to avoid contaminating the transducers. Avoid excess wetting. Place a clean probe on the probe adaptor to protect the sensing mechanism while cleaning. Gently wipe around the cuvette holders or inside the heads. Do not clean the probe mount hubs, unless absolutely necessary. The transducers attached to the probe mount hubs can easily be damaged by debris or liquids. NOTE: Do not use isopropyl alcohol or other solvents on the front panel or LCD cover. Calibration & Service The user cannot calibrate or service the analyzer. Running a reference viscosity QC test (PN 900-1302) will verify if the analyzer is operating within calibration standards. Sienco recommends performing the reference viscosity QC test daily, prior to use of the analyzer. If the analyzer requires calibration or service, contact Sienco, Inc. or your distributor.

Warning and Error Messages The Sonoclot Analyzer will occasionally display messages that may not be familiar. Below are some examples of these messages and procedures to follow, if necessary. “NOISE” indicates that the clot signal is being disturbed by either mechanical noise, such as bumping the analyzer, or by interference between the probe and the cuvette. Check to ensure that the probe is tight against the mount hub and the cuvette is in contact with the bottom of the cuvette holder. The message should disappear within a few seconds. “ERROR” indicates that the self test routine has detected a problem. Normally, the message will disappear after several seconds. You can resume testing then. If the error message remains, make a note of the error number and call Sienco’s service department. “TEST NOT RUN, NOT AT TEMP” indicates that the analyzer is not to temperature and the test was not run. The analyzer must be at 37°C to run a test. “NR” indicates that no results were found for the last test analysis. This can occur due to operator error (i.e. failure to close instrument head within 60 seconds of “Close Head” message), instrument error, or an unusual clot that cannot be analyzed. NUMBERED ERROR CODES: The analyzer is programed to display various numbered error codes. Should your analyzer display a numbered error code, record the number displayed and contact your distributor or Sienco’s service department. If you have any questions in regards to a display message, call Sienco’s service department at 800-432-1624 or 303-420-1148.
