SECTION 1—GENERAL GUIDELINES

 WARNING

SECTION 1 - GENERAL GUIDELINES contains important information for the safe operation and use of this product.

Contraindications

ALWAYS consult the patient’s physician before using the MA50, MA51 and MA55 systems.

Installation

The MA50, MA51 and MA55 systems MUST be installed on medical bed frames with side rails. The side rails MUST be in the raised position whenever a patient is on the bed.

Controls on the footboard may be obstructed by the power unit on a few bed frames. It may be necessary to relocate the power unit. Refer to Installing the Power Unit on page 12.

Check that air hoses and power cord are clear of moving bed components before placing a patient on the bed. Operate all bed frame motorized functions through their full range of motion to be certain that there is no pulling, interference or pinching.

MA51 AND MA55 ONLY - DO NOT strap the mattress to the bed frame at the head and foot ends. Secure ALL mattress straps. Secure the straps to the bed deck at the head and foot ends and to the frame at the center of the bed. Otherwise damage to the mattress will occur when the head and foot ends are raised. Refer to Installing the Mattress on page 10.

Entrapment May Occur

 WARNING

Proper patient assessment and monitoring, and proper maintenance and use of equipment is required to reduce the risk of entrapment. Variations in bed rail dimensions, and mattress thickness, size or density could increase the risk of entrapment. Visit the FDA website at http://www.fda.gov to learn about the risks of entrapment. Review “A Guide to Bed Safety”, published by the Hospital Bed Safety Workgroup, located at www.invacare.com. Use the link located under each bed rail product entry to access this bed safety guide.

Refer to the owner’s manuals for beds and rails for additional product and safety information.

After any adjustments, repair or service and before use, make sure all attaching hardware is tightened securely. Assist rails with dimensions different from the original equipment supplied or specified by the bed manufacturer may not be interchangeable and may result in entrapment or other injury.
