1 – General Information

Make sure the pump is attached securely to the charger, which is connected snugly to an IV pole.

A kinked or occluded IV line may impair the operation of the pump and the accuracy of the infusion. Before operation, verify that the IV line is not kinked or occluded. The BodyGuardTM should be operated only with MicroSetTM. Use of administration sets other than manufacturer-produced BodyGuardTM tubing set may impair the operation of the pump and the accuracy of an infusion. Drugs must not be administered to the epidural space unless the drugs are indicated for this purpose and are administered in accordance with the indications included in the drug manufacturer’s IFU/DFU accompanying the drug. Epidural administration of drugs other than those indicated for epidural use could result in serious injury to the patient. Any adjustments, maintenance, or repair of the uncovered pump may impair the operation of the BodyGuardTM Infusion System and/or the accuracy of the infusion. Only CME authorized technicians should perform any adjustments, maintenance, or repair of the uncovered pump. Any adjustments, maintenance, or repair of the uncovered pump while connected to the power should be avoided. The BodyGuardTM Infusion System should be operated within a temperature range of 18C (59F) to 45C (113F) and at up to 85% humidity. Operating the pump at temperatures and/or humidity other than within this range may affect accuracy. Unsafe operation may result from using improper accessories. Use only accessories and options designed for this system and supplied by manufacturer.

The BodyGuardTM administration sets should not be used for blood, or blood products.

Battery charging is enabled as long as the charger cord is connected to AC power and the pump is in the charger. Switching the pump off does not disconnect it from AC power. To disconnect from AC power, remove the charger cord from AC power. To disconnect pump from AC power, remove it from the charger. Dropping the BodyGuardTM Infusion System could cause damage to components. If the pump is dropped, return the pump for inspection by qualified service personnel. Use aseptic technique. Patient infection may result from the use of non-sterile components. Maintain sterility of all disposable components and do not re-use single use IV sets. When operating the pump in PCA mode with a rate of 0.0 mL/hr there is a hazard of blood clot formation. Connect saline infusion in parallel to avoid this problem. Do not operate the pump near high-energy radio-frequency emitting equipment, such as electrosurgical cauterizing equipment. False alarm signals may occur.

3 – Preventative Maintenance

Procedure 1.

Fill the IV bag with room temperature sterile water. It is important that the water be room temperature so that it does not affect the elastic properties of the silicone replacement pumping segment. Once the IV bag has been filled, use a MicroSetTM to spike the IV bag. Hang the IV bag and the tube set from the IV pole. To prevent fluid coming into contact with the air sensor and pumping mechanism, the infusion bag should be spiked before opening the pump door. Position the bag so that the risk of spillage onto/into the device is minimized. Do not stretch the set when removing it from its packaging or installing it in the pump.

2.

Attach the BodyGuardTM pole mount charger so that the pumping chamber is 10” below the IV bag fluid level. This will ensure that the pumping segment will reach the pumping chamber once the pump has been inserted into the pole mount charger. Load the pump into the pole mount charger and insert the pumping segment of the tube set into the pumping chamber.

3.

Prime the tube set by pressing the PRIME/BOLUS button and set a volume that will completely prime the tube set. The priming volume of the set will be listed on the tubing package (in most MicroSetTM 10 mL will be more than enough volume to expel all air from the set). Once priming is complete, zero the scale then weigh the fluid container and record the result.

4.

Insert the open end of the tube set into the fluid container and start an infusion at a rate of 125 mL/hr at a volume of 25 mL.

5.

Once the infusion has finished, weigh the fluid container and record the result. Subtract the pre delivery weight (the amount from the priming operation in Step 5) from the post-delivery weight. This number is the actual volume delivered. The expected delivery is the volume programmed on the pump to be delivered. Use the following equations to calculate the infusion rate error:

6.

If the results from step 7 is not within the ±5% range the pump must be recalibrated. Begin this process by entering the Technician Menu using the appropriate Technician Code.

7.

Scroll to the option titled Manual Calibrations and press the START/OK button.

8.

Use the following equation to determine the amount of adjustment needed to recalibrate the volume delivery.

9.

Adjust the four volume settings in the Manual Calibration menu by the Correction Value obtained in step 8.
