Warnings Before using the Elevating Base, read through this entire manual. As with all medical equipment, attempting to use this device without a thorough understanding of its operation may result in patient or user injury. This device should be operated only by personnel trained in its operation under the direction of qualified medical personnel familiar with the risks and benefits of this type of device. Additional precautions specific to certain procedures are found in the text of this manual. Do not use the Elevating Base in the presence of flammable anesthetics. A possible explosion hazard exists under these conditions. Safely mounting or dismounting the Care Plus Incubator requires two people. Remove the controller unit before mounting or dismounting the incubator. Always complete the checkout procedure and verify that the incubator is securely mounted before using the base. Always unplug the Elevating Base from the power outlet before any service, cleaning, or maintenance procedure. Plug the unit back in during the procedure only if you are specifically instructed to do so.

1/Introduction 1.1 How to use this manual Thank you for adding the Elevating Base or Stationary Pedestal to your Care Plus system. Please take a moment to review the User Responsibility Statement on the inside of the front cover; it describes what is expected of you to maintain the base. Also read the Warranty on the back inside cover; it outlines Ohmeda’s responsibility in case of a functional defect. This manual is divided into two sections. The first section tells you: • •

How to use the base controls How to test the base before using it with a patient

•

How to clean the base

The second section describes specific service and troubleshooting procedures. Both sections feature individual tables of contents and precautions so that the first five chapters can be stored with the base and the sixth chapter (Service Information) can be stored in the biomedical department. Before you use the base, make sure that you understand the warnings and cautions. Warnings alert you to situations that could injure the patient or the operator. For example:

WARNING

Do not use the Elevating Base in the presence of flammable anesthetics. A possible explosion hazard exists under these conditions.

Cautions alert you to conditions that may damage the equipment. For example:

CAUTION

w Only competent individuals trained in the repair of this equipment should attempt to service it.

1.2 What the Elevating Base can do

CI.07.003

The Elevating Base lets you adjust the Care Plus Incubator to the height that is most comfortable for you. The mattress can be as low as 34 inches (86 cm) or as high as 42 inches (107 cm) above the floor. The foot pedal controls leave your hands free to care for the patient.

Figure 1-1 Different elevations

6600-0114-000 101 1-1 1-1

1/Introduction 1.3 What the Stationary Pedestal offers The Stationary Pedestal provides a movable mounting pedestal for the Care Plus Incubator at a fixed mattress height of 38 inches (97 cm). Equipped with the same casters as the Elevating Base, the Stationary Pedestal and Incubator can easily be moved and then locked in position. The same accessories that are used with the Elevating Base, such as storage modules and rail systems, may also be mounted on the Stationary Pedestal.

6600-0114-000 101 1-2 1-2

2/Getting Started 2.1 Incoming Inspection Inspect the base for any signs of shipping damage immediately after unpacking. If the base or its accessories appear to have been damaged in shipment, file a damage claim with the shipping carrier within 15 days of receipt. Keep all packaging materials until the claim is resolved. Also check the packing slip against the shipment to verify that all accessory devices are present.

2.2 Mounting the Care Plus Incubator 1.Remove the controller from the Care Plus Incubator.

WARNING

 Safely mounting or dismounting the Care Plus Incubator requires two people. Remove the controller unit before mounting or dismounting the incubator. 2.

Lift the Care Plus Incubator onto the base. Make sure that the table top handles face the same direction as the incubator.

3.

2/Getting Started 2.3.1 Units With Pre-Attached Rail Support Bracket Prior to HCB Serial Numbers 1.

Insert the two 3/8 x 2.5 inch, threaded studs from the rail kit into any two of the support bracket mounting holes. Thread each stud five full turns. Refer to Figure 2-3.

2.

Attach the rail assembly to the rail support bracket: a. Remove the cover from the cross rail. Set aside the eight screws and lockwashers for reuse. b. Fit the cross rail over the threaded studs. Note: The threaded studs are alignment guides, not weight bearing supports. c. Continue to support the rails. Insert two, 3/8 inch bolts and internal lockwashers from inside the cross rail. Torque the bolts to 200 ± 5 in. lbs. (22.6 ± 0.6 Nm). d. Remove and discard the threaded studs. Replace them with 3/8 inch bolts and internal lockwashers. Torque the bolts to 200 ± 5 in. lbs. (22.6 ± 0.6 Nm). e. Thread one, 8-32 x 1/2 inch grounding screw with a #8 lockwasher from the rear of the cross rail into the rail support bracket.

CAUTION

w  Make sure that the rail support bracket is securely attached to the rails. The bolts must be torqued to 200 ± 5 in. lbs. (22.6 ± 0.6 Nm).

3.

Replace the cross rail cover, using the eight screws and lockwashers previously removed. Note: To install a storage module, continue with the next Section, Mounting a Storage Module. To mount the incubator, see Section 2.2, Mounting the Care Plus Incubator.

2.5 Checkout Procedure WARNING

CAUTIONS

Always complete the checkout procedure and verify that the incubator is securely mounted before using the base. 1.

Check for external damage.

2.

Make sure that the incubator is securely mounted to the base.

3.

If a rail system is attached to the base, check that accessories are securely mounted and that their weight is evenly distributed between the two rails.

w Rail mounted accessories should not exceed 20 lbs (9 kg) on either side. Total

accessory weight, including items placed on the overhead shelf, must not exceed 90 lbs (41 kg).

w All rail mounted accessories except IV poles must be mounted below the accessory weight caution label.

4.

Make sure that the casters are securely attached.

5.

Verify that the base rolls freely when the brakes are not set. Then, set the brakes and verify that the base stays in place.

WARNING

Always set the brakes before placing a patient in the incubator. For Elevating Base models only, proceed with steps 6-9. For Stationary Pedestal models, proceed to step 10. 6.

WARNING

Verify that the area is free of flammable anesthetic agents and other flammable substances. Do not use the Elevating Base in the presence of flammable anesthetics. A possible explosion hazard exists under these conditions.

7.

Verify that the power cord is tightly plugged into the Elevating Base’s socket. If necessary, loosen the plug guard and connect the power cord. Then, reposition the plug guard and tighten the screws. Plug the other end of the cord into a power

2/Getting Started outlet (Figure 2-11). On units with HCB serial number a green power indicator lamp located at the Elevating Base foot switch should illuminate. 8. Depress the M pedal and verify that the incubator mattress rises to approximately 42 inches (107 cm) above the floor.

WARNING

Before raising or lowering the base, check that there is adequate slack in tubing and cable connections and that no obstructions (e.g. shelves, etc.) limit the range of motion. 9. Depress the ? pedal and verify that the incubator mattress lowers to approximately 34 inches (86 cm) above the floor. 10. Before using the Care Plus system with a patient, verify proper operation of the incubator and all other system components.
