ACCESS CODE LIST

The T34 syringe pump has 2 access codes & a Key lock feature to control user access to authorised personnel only and prevent tampering. Service Technicians will need to be familiar with these codes to access all area of the pump to effect service and repair.

Code ‘99’ – Access to pump “Change Set-up” allows locking program parameters.

Code ‘123’ – Allows authorised technicians to access testing and service menu.

Key lock – Enables user to lock all but the INFO and STOP keys to prevent tempering with the pump

BEFORE PERFORMING ANY MAINTENANCE PROCEDURE:-

a. You must have training and certification from either the manufacturer

or distributor and have recommended equipment and authorised spare parts at hand to perform the required maintenance or repair.

b. Check the history events to define the frequency and nature of the

complaint, and record program and calibration settings at time of the event.

c. Enter the Technician menu (power on the pump while holding the INFO

& POWER key simultaneously until the Technician Code prompt appears). Enter code 123. Press YES key to confirm

SERVICE DECISION PATHWAY

When a T34 syringe pump is returned for service or repair after a ‘fault’ is reported by a user always request a full explanation and description of the fault experience by the user and, if possible and appropriate, ask for the return of the administrator set in use at the time of the fault. Be mindful of the following factors as part of service/repair procedure:-

1. Has the user operated the pump correctly? Cross reference their report with the

Operations manual to ensure the steps they took prior to the alarm did not cause or result in the alarm state or error cause.

2. Was the fault in one of the pump sensors (identify which one and replace it) or one

of the circuit boards (identify which PCB failed and replace the board). Use on the Technician mode, either, Main Self test to pass all the testable options or Manual Test to select a specific function.

Possible Issues:-

OPERATIONAL CHECKLIST

INTRODUCTION

The operational checklist detailed in this section determines if the device is operating correctly and should be carried out before and after any service or repair work. If the device fails in any test in the checklist, the fault must be recorded and corrected prior to placing the device back in to clinical use. Please become familiar with the checklist procedures prior to carrying out any test.

The following test equipment is required to perform the tests in the Operational Checklist:-

o Syringe 50/60 ml filled with tap water o Pressure gauge o Electronic balance, burette or Infusion tester. o Leakage current testing device (for safety test) o Connecting flat cable between front and rear housing

Once a problem has been identified and isolated to a single assembly, the assembly should be replaced in accordance with the disassembly procedure provided in this manual.

After all repairs are completed, the Operation checklist should be repeated and the device should be re-calibrated.

PUMP SET UP FOR TESTING

Please ensure you have, & are familiar with, the device Operation Manual before performing these tests. The procedure in this section are designed to check that the syringe pump is infusing correctly prior to testing the effectiveness of the alarms. If the pump fails to perform as described or displays an error cause – troubleshoot and repair before repeating the test. The pump will display Restart Pump message, press the info key for more details

1. Switch the pump on; allow preloading procedure to be completed. Verify that the syringe

holder is set down.

2. Verify that all sensors (syringe holder, barrel ear and plunger ear) are blinking.

3. Load a syringe, verify that the pump detects the syringe size and brand; the pump may

detect a different brand but never a different size. (see Operation Manual)

4. Select the correct brand and press YES to confirm

5. The pump will display the calculated volume. Verify this detection is correct, if not return

to step 1

6. Confirm or change data of time default, calculated rate, and accumulated screen, start

infusion

SYRINGE RECOGNITION AND VOLUME DETECTABLE TEST.

Equipment needed:-

• T34 syringe pump

• Selection of syringes used in the hospital or Trust.

Method

1. Switch the pump on and allow Pre-loading to complete. Position of the carriage should

not be important except possibly for some smaller syringes where the actuator may have moved beyond the fully extended size of the syringe. Use the FF keys to move the activator to time desired positions. FF key movement is limited for safety reasons so repeated presses may be necessary to position.

For each of the syringe: -

2. Lift the barrel clamp arm and place the syringe on the pump as described in the

Operations manual ensuring the collar/flange and plunger are position correctly. Place the barrel clamp arm down on top of the syringe barrel.

3. The LCD screen should show the LOAD SYRINGE message and after a few seconds a

volume and brand. If this screen remains with parts of-the syringe graphic flashing (or a message is shown) check the loading of the corresponding syringe part or follow the message to complete correct placement of the syringe.

4. The pump should ALWAYS display the correct volume but may not always immediately

give the correct brand. Use the arrow keys to scroll through the list of syringe brands (pump shows those within +/'-3% diameter of the one loaded). Select the correct syringe brand and press YES to confirm selection.

5. Read the actual volume on the syringe and compare it with what the pump reads the

volume as, these results should be within +/-3%. If the result does not fall within the expected range

a. Check that there is no slack in the system (visible space in the seating of the

plunger or the collar/flange. In such cases purge may, be required before repeating the test (refer to Operations Manual)

b. Recheck that the syringe loaded is the same brand as confirmed at step 4

i. I f the error remains outside of specification after checking point a & b

then the pump has failed the test and corrective action is required.

6. Remove the syringe, turn the pump off, place arm down and repeat steps 1-5.

Service & Repair Manual

19/06/2007

VOLUME DELIVERY TEST

Equipment needed:-

• 10ml syringe filled with tap water for injection

• Syringe pump infusion set

• Pipette or Flow analyser.

1. Prepare the syringe and infusion set by attaching set to the syringe and manually

priming the infusion set to eliminate ALL air from the system

2. Attach infusion set to analyser or pipette ( using a three way valve to allow the pipette

level to be adjusted to scale )

3. Switch the pump on with barrel clamp arm down and allow Pre-loading to complete.

4. Position the carriage to fit the syringe using the FF or BACK keys.

5. Lift the barrel clamp arm and load the syringe. Use the arrow/scroll keys to select the

correct make from the list (as described in the Operations manual). Press YES to confirm selection

6. Purse the system to ensure all the slack is taken up. With the voluble displayed press

the FF key and follow the instructions on screen. (Default purge volume is 0.2ml)

7. Change volume to be infused to 1m by using the arrow keys. Press YES to confirm

8. To speed up the test scroll down to reduce the duration of the infusion to the in

minimum allowed (scrolling will cease when the minimum is reached – if 1ml volume is selected this should be 00:12 (twelve minutes))

9. Pump will display rate but will not allow change. All changes to rate must be done by

Pressing NO to back up to Duration screen and changing the duration. Confirm Rate 5ml/hr. Press YES three further times to start infusing

10. The Near End Alarm will sound at about 1 minute before the end depending on

syringe size.

11. The T34 will alarm End Of Program or End Travel when it has delivered the 1ml

12. Check volume delivered against the volume in pipette.
