General layout

Operation

Pre-Operation Check
Move the bed into the position where it is going to be in operation. Allow for a 50mm to 75mm gap between bed head end and the wall. Connect the mains plug to the 240V supply. Take up the excessive length of the power supply cable and attach the excess cord to the head end bar with a cable tie if necessary.

WARNING
Ensure the cord has enough slack when connected so that it is not stretched when the bed is operated or moved to enable cleaning under it Prevent the cord from getting under the bed or the wheels or entangling in the moving parts of the bed as damage to the mains cord may cause the bed to become live.

Safety

•  Always use a mattress of the correct size and type. A range of suitable pressure reducing and pressure relieving mattresses is available from ArjoHuntleigh.
•  When the bed is operated, make sure that obstacles such as bedside furniture do not restrict movement.
•  Before operating the bed, make sure that the patient is safely positioned to avoid entrapment or imbalance.
•  Before moving the bed, make sure that the bed is at a suitable height for the attendants to move the bed without stooping or straining.

WARNING
When the patient’s condition could lead to patient entrapment, the mattress support platform should be left in the flat position whilst unattended.

Always apply the brakes when the bed is stationary. When operating the bed in tilt mode, apply the brakes at one end only.

WARNING
Lower the bed to minimum height when the patient is left unattended to reduce the risk of injury due to falls whilst getting into or out of the bed, or whilst lying on the bed\

WARNING
The clinically qualified person responsible should consider the age, size and condition of the patient before using the bed or accessories.

WARNING
Always ensure that all hospital lines and power cables are free from possible entanglement with mechanical parts of the bed. Always ensure that attendant and patient limbs are free from potential entrapment areas before operating any functions.

•  Do not expose the equipment, especially the mattress, to naked flames such as cigarettes etc.
•  Use only ArjoHuntleigh accessories designed or approved for use with the bed.
•  Keep these instructions handy for reference.

Brakes
To operate braking, push down on the brake lever on each castor.

WARNING
Brakes should be activated at all times whilst bed is stationary.

Power Operation

The bed height, backrest angle, Trendelenberg tilt angle and leg elevation functions are all electrically operated using control handset. To operate a function, press and hold the appropriate pushbutton until the desired position is achieved. To stop at the required position release the button. The Auto- contour button operates both backrest and leg elevation simultaneously.

WARNING
Some functions may cause injury to the patient if unintentional movement occurs. ArjoHuntleigh strongly recommends that handset is locked out when no movement of bed functions is required by activating Magnetic handset lockout feature.

WARNING
If the Handset sustains any damage or suspected damage in any way, immediately stop using the Handset, apply magnetic lockout function and perform the full Handset Checks as detailed in Section 7 – Maintenance.

To operate the bed press and hold the desired function button. Adjustment will stop when the button is released, or the movement selection reaches the end of its range of adjustment.

Backrest Angle Adjustment
Pressing the button with the arrow pointing up, raises the backrest. Pressing the arrow down button lowers the backrest back to a flat position.

Knee Break Adjustment
Pressing the arrow up button raises the thigh section. When the thigh section is first raised from the flat position, the calf section will be in the Fowler position (angled downwards) To change the calf section to the vascular (horizontal) positon, refer to Calf Adjustment section on page 8.Pressing the down button returns the thigh section back to a flat position.

Auto Contour Adjustment
Pressing the Auto Contour arrow up button raises the backrest and thigh sections simultaneously to provide upright patient profiling. The raised thigh section prevents the patient from sliding down the bed. Pressing the arrow down button returns the platform back to a flat position.

Mattress Platform Height Adjustment
Press the button with the arrow pointing up to raise the mattress platform height. Press the arrow down button to lower the mattress platform.

Mattress Platform Tilt Adjustment
Pressing the arrow down button lowers the head end of the mattress platform (Trendelenburg position) Pressing the arrow up button lowers the foot end of the mattress platform (reverse Trendelenburg position)

UNDER BED LIGHT (night light) if fitted
To turn ON simultaneously press the top two buttons. To turn OFF repeat the above. Each time the electricity supply is disconnected the Function Lock engages by default rendering all functions inactive. To re-enable the functions, swipe the magnetic key past the lock icon on the handset (Fig 3) and the indicator light will reflect the status. If it becomes necessary to deactivate bed functions, swipe the magnetic key past the lock icon again. The Magnetic key should remain in the possession of the carer or supervising staff if the occupant of the bed is not in control of all their faculties.

WARNING
Depending on the clinical condition of the patient, it is strongly recommended that the Trendelenburg function is locked out via the magnetic handset lockout feature

Calf Adjustment
When the thigh section is raised via the handset, the calf section can be manually changed to the vascular (horizontal) position. Holding the Calf frame by both foot-end corners, lift the panel upwards and allow it to lock at the various intervals the catch allows it to. To return the Calf section back to the Fowler position, lift the panel to its full extension and then lower slowly.

NOTE : Always return Calf section back to Fowler position prior to lowering Knee Break adjustment.

Mattress Platform Extension
If the bed is tilted use the bed hand control to level the mattress platform, prior to carrying out this operation. Refer to the Power Operation section on page 6. Adjustment is possible by means of two knobs located behind the foot panel on the upper side of the Extension slide tubes.

To extend the mattress platform:
Applying finger pressure, simultaneously press down on both red coloured knobs and slowly pull the foot panel towards you. Once the frame begins to slide out, release both knobs and extension frame will click-lock in position at 180mm fully extended.

To retract the mattress platform:
Repeat the above procedure, however push the extension in rather than pulling it out.Always check that lock has engaged correctly once an adjustment is made.

WARNING
Platform Extension Safe Working Load is 20kg. Adjusting the bed to a Reverse Tilt (foot-down tilt) position with the mattress platform extended can potentially create a foot trap. Always install a suitable mattress extension (bolster) when bed is extended

Acute Care Bed model
Emergency Release Backrest. (CPR Function)
This bed is fitted with an emergency release lever so that the backrest may be quickly lowered to the horizontal position in the event of a requirement to perform CPR. The bed is fitted with a gas strut to cushion the descent. To operate the emergency release when the backrest is in the upright position, grasp the backrest panel and gently but firmly pull the red Emergency Release lever
(positioned below the backrest) outwards which will disengage the actuator. The backrest will descend to its resting position.

The quick-releas lever is located on both sides of the bed so as to enable it to be operated from either side of the bed.Once in the lowered position, the back rest may be operated normally using the hand control.

Patient Transfer
If the patient is to be transferred by means of a patient hoist, the bed will need to be raised enough to allow hoist access underneath the bed.

WARNING
Bed functions, particularly Hi-Lo are NOT to be used during patient transfer.

Cleaning

WARNING
Disconnect the bed from the mains power supply before cleaning. Gloves and protective clothing should always be worn when carrying out cleaning procedures.

These instructions also apply to accessories but not to mattresses.

Wipe all surfaces with a soft cloth moistened with hot water and mild detergent (or the hospital’s recommended cleaning solution). Take extra care with areas that may harbour dirt or dust.
Rinse with clean water and dry with paper towels. To remove potentially infectious material such as body fluids, or when the bed has been used by someone with a known infection, clean afterward with NaDCC (e.g. Presept, Actichlor) at 10,000 ppm of available chlorine. Rinse and dry. Allow the cleaned parts to dry before replacing the mattress.

Caution
Do not use abrasive compounds or pads. Do not use hypocarb onate or phenolic cleaning solutions.

Maintenance / Troubleshooting

The following preventive maintenance procedures should be carried out at intervals of 6 and 12 months. All service or repair activities must only be performed by properly qualified and trained persons who are approved by ArjoHuntleigh. The disposal of products and components should be compliant with local regulations.

WARNING
Disconnect the bed from the mains power supply before starting any maintenance activity. Avoid skin contact with lubricants.

General 6 month Routine Maintenance

• Examine flexible cables for cuts, abrasions, kinking or other deterioration. Make sure that the electrical supply cable plug is not damaged.
• Check that wiring is secure and not interfering with bed movement.
• Wipe external actuator shafts to remove dust and lint. (Do not wash)
• Check that all bed functions are operating correctly.

General 12 Routine Maintenance

• Examine the bed for obvious signs of damage. All aspects of the equipment should operate as intended.
• Make sure all nuts, bolts and other fastenings are tight and are not missing. Check all pivot points for significant wear or any damage.

Castors and Brakes

• Apply the brakes and push the bed forwards. If any of the castor’s brakings is inefficient then they should be replaced.
• Check that castors swivel and rotate freely.
• Remove any fluff or threads picked up by the castors.

HANDSET Checks
Between each patient, ArjoHuntleigh strongly advises that the Handset is visually inspected for obvious damage before each use if practicable and that Preventative Maintenance checks are conducted on the handset. When using a specific function staff should be aware of, and checking for, any of the symptoms listed in point 3 below.

Preventative Maintenance Checks
ArjoHuntleigh recommends that the full check and testing regime is conducted between each bed use or worst case during annual Preventative maintenance. This should take no more than one (1) minute to complete.

WARNING
Although preventative maintenance checks may identify damaged or faulty handsets which could lead to unintentional bed movement, ArjoHuntleigh strongly recommends that the handset is locked out when no movement of the bed functions is required. This is done by swiping the magnetic key over lock icon on the handset. (Operation page)

Visual inspection of handset casing

1. Inspect the outer plastic casing for any obvious cracks or damage.
2.  Inspect for damage to the front cover (outer label) particularly over the buttons where the label may be torn or indented.

If any damage is identified while conducting checks 1.1 and 1.2, immediately quarantine the bed and report the damage to maintenance staff or replace the Handset.

Visual inspection of the cable and Cable insulation:

1. Inspect the cable for any nicks or cuts in the insulation
2. Inspect for any evidence that the cable may have been squashed or flattened. Squashed or flattened cables may indicate a possible break in the internal conductors or insulation causing conductors to short together which could cause unwanted movement of the bed. Any handsets are found with obvious damage to the cable insulation, immediately report the damage to maintenance staff or replace the Handset

Tactile inspection of the buttons:
All buttons and magnetic locking functions should be operated and response tested. Depress each button on the handset. Each button should have a positive audible click that is also felt. The function being pressed should also operate. If the button:

•  does not have a click feel
•  does not have an audible click sound
•  does not immediately operate the function
•  feels soft offering no resistance
•  feels different to the rest of the buttons
•  travels further when depressed

Immediately quarantine the bed and report the damage to maintenance staff or replace the Handset, otherwise contact an ArjoHuntleigh approved Technician.

CONTROL BOX SAFETY FEATURE

• The electric system has a 10% duty cycle i.e. 2 minutes of operation followed by 18 minutes of rest. If either the rated load or the duty cycle is exceeded, the self-resettable fuse will activate.
• Repeated activation of the self-resettable fuse will result in relay failure.
• The actuator will slowly retract under load to a rest position if it is deprived of low electrical resistance which enhances the braking power.
• This slow retraction is meant to avoid a catastrophic failure in the event of overload.
• If any of the functions are seen to be slowly creeping down, contact a trained technician.
