3.10 Inserting the Test Card The epoc Reader must be placed on a stable horizontal surface, such as a tabletop, prior to inserting the Test Card. Never insert anything except a Test Card into the Reader’s Card Insertion Slot.

This side up

Position the Test Card with the Blue Label side facing upwards and the Sensor Module towards the Reader. Test Cards are “keyed” using a notch in the corner to ensure correct card orientation during insertion. Insertion of a Test Card causes the Barcode Reader in the Reader to turn “ON.” Insert the Test Card into the Reader’s Card Insertion Slot at the front of the Reader with a smooth single motion to enable the Barcode on the Card Label to be correctly read by the Reader during insertion.

Continue inserting the Test Card until slight resistance is felt. Push the Test Card past this point to “lock” it into place. This is the final Test Card position. Avoid abrupt stops or unevenness in speed during Test Card insertion. Upon correct Test Card insertion, the Reader is configured for the card type indicated by the Test Card Barcode. The Reader performs a series of card integrity checks. The Reader beeps once, and the Test Status Indicator turns solid green to notify the user that the Test Card has been successfully inserted. Any problem reading the Barcode (or any other error) causes the Test Status Indicator to turn solid red. Check the Host for an error message and completely remove the Test Card from the Reader. Reinsert the card for successful insertion confirmed by a solid green Test Status Indicator.

3.11 Calibration Sequence Once the Test Card is successfully inserted, a motorized mechanism in the Reader can be heard as the calibration fluid is released over the sensors within the Test Card. The Test Status Indicator on the Reader flashes green to indicate the start of the test calibration sequence. The Host confirms the start of the test by entering the calibration mode and displaying the calibration progress.

51011600 Rev: 00

epoc System Operation

3-5

The calibration process takes approximately 165 seconds to complete. During this time, the user can prepare the patient and obtain a blood sample. The Reader must rest on a flat horizontal surface without movement for the duration of the test.

3.12 Entering Patient Information (or Lot Number) and Test Selection The Patient ID and related information can be entered at any time during the test. For a Blood Test, the Patient ID number is entered to identify the test results for the Test Card used for the test. For a QA Test (not shown), the QA fluid Lot Number is entered instead of the Patient ID. Select the Test Information Tab on the Reader Screen to enter the patient information. The Administrator may require Sample Type or Hemodilution entries. Using the arrow , additional settings related to respiratory therapy, age, and gender may be entered. Patient information entered prior to completion of the test is saved automatically with the test results when the test is complete. Patient information entered after the test is complete, but before the next test starts, must be saved by tapping the Save

button.

The Test Information Page for performing QA test contains only the Comments field (not shown). If the Patient ID is not entered prior to completion of the test, the user is prompted to enter the Patient ID when the test results are displayed. Exercise care when entering Patient ID and other information. Ensure the correct Reader is selected by verifying that the Reader name corresponds with the Reader used to conduct the test.

51011600 Rev: 00

Select the Test Selection Tab on the Reader Screen to select or deselect analytes to display in the test results. The system administrator settings may require analyte selection before results are displayed. Additional analytes may be selected after test completion. Once test results are displayed, analytes can no longer be de-selected.

3.13 Using Barcode Scanner to Enter Patient ID Press the stylus in the Patient ID field. A cursor appears. Activate the Barcode Scanner by pressing any of the Scan buttons on the epoc Host. The Barcode Icon at the top of the screen indicates when the barcode scanner is ready to scan. Point the light coming from the top of the Barcode Scanner towards the desired barcode until a beep is heard. The scanner turns off. The scanned text appears in the field where the cursor was left. Warning: Never look directly at the laser light. Point the laser only at a barcode and away from the eyes at all times. The Patient ID may also be entered using the stylus and the Onscreen Keyboard accessible from bottom of screen via the Text Input button.

3.14 Collecting a Blood Sample Read information on Sample Collection in the BGEM Test Card Specifications section of this Manual to ensure that blood samples are properly collected and handled for testing.

3.15 Timing of Sample Introduction After about 165 seconds of calibration the Test Status Indicator stops flashing green indicating that the Test Card is ready to receive a test sample. The epoc Host displays the message, “Inject sample….” The screen has a bar indicating the time remaining to introduce a sample. The blood sample must be introduced into the Test Card during this 450-second (or 7.5-minute) period. Introducing the sample too soon or too late will cause an error and abort the test. A new Test Card must be inserted and the test procedure started again.

3.16 Sample Introduction 1. Hold the syringe barrel vertically between finger tips and thumb (as shown in Figure 1). Keep Syringe vertical and perpendicular to the Test Card to avoid sample spillage. Complete steps 2 and 3 below in one continuous motion to ensure best performance of sample introduction. 2. Using slight downward pressure, secure the syringe’s luer tip into the center recess of the blood sample entry port of the Test Card. Rotate the syringe up to 1/4 turn to ensure a good seal (as shown in Figure 2).

Figure 1

The User should feel the syringe tip engage with the rubber seal of Test Card entry port. Press the syringe with enough downward force to engage the syringe tip with the blue rubber seal. 3. While maintaining downward pressure, use index finger of the other hand to steadily depress the syringe plunger with a single, smooth, continuous motion until prompted to stop (as shown in Figure 3).

Figure 2

The Reader provides an audible beep and the Test Status Indicator flashes green indicating enough sample for analysis was received. The Host also displays sample acceptance. Learn to use the audio and visual feedback to perform this step easily and reliably. A normal dispense operation takes about 1 second or less. Sample introduction should never exceed 2 seconds. Failure to heed the audio or visual prompts may cause the sample to flow from the vent hole at end of the Test Card waste chamber and possibly into the epoc Reader.

Figure 3

Never attempt to clean inside the Reader. Avoid rapid sample introduction because it can cause fluid segmentation. This condition is detected by the system. The test is aborted, and the Host displays an error message. The Reader automatically analyzes the test sample. The analysis process takes about half a minute.
