Introduction WARNING / CAUTION / NOTE DEFINITION The words WARNING, CAUTION and NOTE carry special meanings and should be carefully reviewed. WARNING Alerts the reader about a situation, which if not avoided, could result in death or serious injury. It may also describe potential serious adverse reactions and safety hazards.

CAUTION Alerts the reader of a potentially hazardous situation, which if not avoided, may result in minor or moderate injury to the user or patient or damage to the equipment or other property. This includes special care necessary for the safe and effective use of the device and the care necessary to avoid damage to a device that may occur as a result of use or misuse. NOTE This provides special information to make maintenance easier or important instructions clearer.

SAFETY TIPS AND GUIDELINES Before operating the Epic II
and Epic II
+ Critical Care Beds, it is important to read and understand all information in this manual. Carefully read and strictly follow the guidelines listed on this page and the following pages. To ensure safe operation of the bed, methods and procedures must be established for educating and training hospital staff on the intrinsic risks associated with the usage of electric beds.

   



 

WARNING The Epic II
Critical Care Bed is equipped with a hospital grade plug for protection against shock hazard. It must be plugged directly into a properly grounded three−prong receptacle. Grounding reliability can be achieved only when a hospital grade receptacle is used. Serious injury can result if caution is not used when operating the bed. Operate bed only when all persons are clear of the electrical and mechanical systems. To help reduce the number and severity of falls by patients, always leave the bed in the lowest position when the patient is unattended. When raising the siderails, listen for the ”click” that indicates the siderail has locked in the up position. Pull firmly on the siderail to ensure it is locked into position. Siderails are not intended to be a patient restraint device. It is the responsibility of attending medical personnel to determine the degree of restraint and the siderail positioning necessary to ensure a patient will remain safely in bed. Always apply the caster brakes when a patient is getting on or off the bed. Always keep the caster brakes applied when a patient is on the bed (except during transport). Serious injury could result if the bed moves while a patient is getting in or out of bed. After the brake pedal is applied, push on the bed to ensure the brakes are locked. When moving the bed, toggle the steer pedal to put the bed in the steer mode. This locks the swivel motion of the right foot end caster and makes the bed easier to move. Ensure the brakes are completely released prior to attempting to move the bed. Attempting to move the bed with the brakes actuated could result in injury to the user and/or patient. Assistance is required to lower the Back if the angle of the Back is greater than 80 when the CPR emergency release is activated. Attempting to lower the Back in this position without assistance may result in injury to the operator.

Introduction SAFETY TIPS AND GUIDELINES CONTINUED 

The Bed Exit System is intended only to aid in the detection of a patient exiting the bed. It is NOT intended to replace patient monitoring protocol. The bed exit system signals when a patient is about to exit. Adding or subtracting objects from the bed after arming the bed exit system may cause a reduction in the sensitivity of the bed exit system.



If the bed is equipped with the Epic II
+ option, there is a power save mode. The power save mode is activated after one hour on battery power with no motion release switch activation. Functions including Bed Exit, scale and motion will cease to operate when the unit enters the power save mode. Injury to the patient could occur if proper patient monitoring protocol is not observed. Due to the weight the battery back−up option adds to the bed (approximately 50 pounds), additional force is required to move a bed equipped with the Epic II
+ Option. Caution should be used when transporting this bed. Additional assistance should be used when necessary. Failure to use caution while transporting this bed may result in injury to the user.



       

Always unplug bed during service or cleaning. When working under the bed, always place blocks under the litter frame to prevent injury in case the Bed Down switch is accidently activated. The battery tray assembly weighs 50 pounds. Take care when removing the two hex head screws securing it to the base frame or personal injury could result. Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling. The Epic II
Critical Care Bed is not intended for pediatric use or for patients under 50 pounds. Explosion Hazard − do not use bed in the presence of flammable anesthetics. To avoid entanglement, possibly resulting in frayed power cords and risk of electrical shock, wrap the bed power cord around the roller bumpers at the head end of the bed during transport. Service only by qualified personnel. Refer to the maintenance manual. V erify the power cord is unplugged and the battery power switch (Epic II
+ option) is turned to the off position before servicing. When using the Symmetric AireTM Mattress extra caution and or operator supervision is required to help reduce the likelihood of a patient fall occurring.

To avoid possible injury and to assure proper operation when using a powered mattress replacement system such as XPRT:



Confirm proper scale system operation following mattress installation. For best results, secure the therapy mattress power cord to prevent damage to the cord or interference with the bed frame and the scale system.



Do not zero bed scales or weigh patient with Percussion, Vibration, Rotation or Turn−Assist active. Patient motion and position resulting from the dynamic therapy mattress may adversely affect scale system performance.



Do no initialize (“arm”) bed exit with Percussion, Vibration, Rotation or Turn−Assist active. The patient motion and position resulting from the dynamic therapy mattress may adversely affect bed exit system performance.



When using an XPRT Therapy Mattress extra caution and or operator supervision is required to help reduce the likelihood of a patient fall occurring.

Introduction SAFETY TIPS AND GUIDELINES CONTINUED CAUTION



  



Scale function may be affected by siderail/caster interference. With the litter fully lowered or lowered in Reverse Trendelenburg, the siderails tucked under the litter in the storage position and the casters turned, there is the potential for interference between the siderail and the caster. Raise the siderails when lowering the litter to the full down position to prevent the interference from causing the bed’s scale system to weigh inaccurately. The lockout buttons on the foot board lock the Fowler, Gatch and Bed Up/Down functions and prevent motion of the bed. It is the responsibility of attending medical personnel to determine whether these functions should be locked and to use the buttons accordingly. Because individual beds may have different options, foot boards should not be moved from one bed to another. Mixing foot boards could result in unpredictable bed operation. If large fluid spills occur in the area of the circuit boards or motors, immediately unplug the bed power cord from the wall socket. Remove the patient from the bed and clean up the fluid. Have maintenance completely check the bed. Fluids can short out controls and may cause the bed to operate erratically or make some functions completely inoperable. Component failure caused by fluids could cause the bed to operate unpredictably and could cause injury to the patient. DO NOT put the bed back into service until it is completely dry and has been thoroughly tested for safe operation. Preventative maintenance should be performed at a minimum of annually to ensure all features are functioning as designed. Close attention should be given to safety features including, but not limited to: Safety side latching mechanisms Caster braking systems Leakage current 300 microamps max. No controls or cabling entangled in bed mechanisms Frayed electrical cords and components All controls return to off or neutral position when released

  

The siderails are not intended to be used as a pushing device. Damage to the siderails could occur.

  

The weight of the IV bags should not exceed 40 pounds.



IV Poles should not be used as a bed push/pull device.

The use of a mattress overlay may reduce the effectiveness of the siderail. When attaching equipment to the bed, ensure it will not impede normal bed operation or patient injury could occur. For example: hooks on hanging equipment must not actuate control buttons, equipment must not hide the nurse call button, etc. Do not add or remove weight when the bed exit system is armed. The cleanliness and integrity of both ground chains must be maintained to minimize static build−up and discharge.

The following Caution statements apply to the optional outlet:

     

Maximum total load 5A receptacle rating: 125VAC, 5A, 60Hz. The total system chassis risk current should not exceed 300uA Grounding continuity should be checked periodically. Do not use for life−sustaining equipment. Use only hospital−grade equipment with electrical outlet. Unplug free−standing equipment before transporting the bed.

Introduction SET−UP PROCEDURES It is important that the Epic II
Critical Care Bed is working properly before it is put into service. The following list will help ensure that each part of the bed is checked.



Plug the bed into a properly grounded, hospital grade wall receptacle. WARNING

The Epic II
Critical Care Bed is equipped with a hospital grade plug for protection against shock hazard. It must be plugged directly into a properly grounded three−prong receptacle. Grounding reliability can be achieved only when a hospital grade receptacle is used.



Depress the pedal at either side of the bed fully to set the four wheel brakes and ensure all four casters lock. Depress the pedal again to release the brakes.

    

Toggle the steer pedal to put the bed in the steer mode and ensure the locking caster engages.



If the bed is equipped with the Epic II
+ battery backup option, unplug the power cord from the wall socket. Push the battery power switch located on the lower left corner of the head end to the “ON” position. Again, verify each function on the foot board and siderails is operating properly. The 12 volt batteries that provide back−up power to the unit functions with the Epic II
+ option will charge whenever the power cord is plugged into the wall socket. The batteries require approximately 10 hours of charging time before the bed is put into service.



If the bed is equipped with the Nurse Call option, verify it is functioning properly prior to patient use.

Ensure the siderails raise and lower smoothly and lock in the up and intermediate positions. Run through each function on the foot board control panel and ensure that each is working properly. Ensure all functions are working properly on the siderail controls. Raise the Back up to approximately 60 . Squeeze the CPR release handle and ensure the Back and Knee will drop with minimal effort.
