Figure 1-1 Enterprise® 8001B bed All power-operated functions are operated by push button controls. The user must select a function, then the press the up or down Direction key to drive the bed to the required position. The user control panels are integrated into the head end safety side modules, with the patient’s controls on the inside face and the nurse’s controls on the outside. The patient’s controls adjust backrest angle and leg elevation; the nurse’s controls additionally adjust bed height. The bed has attendant control panels (ACP) integrated into the foot end safety side modules, from which the power operated functions can be disabled; operation of the bed by the patient is thus at the discretion of the carer. The ACP contains pushbutton controls for all bed movements including tilt, CPR and Vascular/Fowler profile selection. An on/off switch for the optional underbed light is also provided. The electrical actuators consist of a screw and nut assembly driven by a 24V d.c. motor and gearbox. Power for the actuators is derived from an a.c. power supply located below the head end of the bed. The electronic control unit is mounted underneath the seat section.

OPERATIONAL MAINTENANCE

2.1

General

The equipment has been designed to be virtually maintenance-free between service intervals. The degree of periodic cleaning and maintenance necessary will be determined by use and condition. Examine the bed for obvious signs of damage. If found take appropriate remedial action.

WARNING Disconnect the bed from the mains power supply before carrying out cleaning procedures. 2.2

Cleaning

Wearing suitable protective clothing, clean all surfaces with a disposable cloth soaked in a neutral detergent and hand hot water. The mattress platform sheets and head/foot end panels can be removed from the bed and cleaned separately. Start by cleaning the upper sections of the bed and work along all horizontal surfaces. Work methodically towards the lower sections of the bed and clean the wheels last. Take extra care to clean areas that may trap dust or dirt. Rinse with clean water and dry with disposable paper towels. Allow the cleaned parts to dry before replacing the mattress. 2.3

Disinfecting

After cleaning the bed as described above, wipe all surfaces with sodium dichloroisocyanurate (NaDCC) at a concentration of 1,000 parts per million (0.1%) of available chlorine. In the case of pooling body fluids, e.g. blood, the concentration of NaDCC should be increased to 10,000 parts per million (1%) of available chlorine. Caution Do not use abrasive compounds or pads. Do not use phenol-based disinfectant solutions.

PREVENTIVE MAINTENANCE

The following preventive maintenance checks and procedures should be carried out every 12 months. All service and repair activities must only be carried out by properly qualified and trained persons approved by ArjoHuntleigh. Disposal of product and components should be compliant with local regulations.

WARNING Before starting any maintenance activity, disconnect the bed from the mains power supply. The bed sections will still operate on battery power unless the function has been disabled on the ACP. Avoid skin contact with lubricants. Gloves and protective clothing should be worn when carrying out maintenance work. 3.1

General

Examine the bed for obvious signs of damage. Make sure that all visible fixings and fastenings are secure and not missing. Examine all flexible cables for cuts, abrasions, kinks or other deterioration. Check the mains plug and cable for damage. If either the mains plug or cable is damaged, both must be replaced as a complete assembly. Under no circumstances should the fitted moulded plug be replaced with a rewireable plug. 3.2

Castors and Brakes

Check the brakes for efficient operation. Check that the steering lock operates effectively. Poor braking or steering performance indicates that one or more castors require replacement.

3-1

746-559-2 05/10

4

TESTING

The following serviceability tests should be performed before returning the bed to use after service, or if any function is suspect. These instructions should be read in conjunction with the product user manual, part number 746-435. If the result of any test is unsatisfactory, investigate and take the appropriate remedial action. Refer to Chapter 5, Troubleshooting and Chapter 6, Servicing Instructions.



All references to left or right of the bed are when viewed from the head end (i.e. by a patient lying supine on the bed).

WARNING If any electrical assembly or wiring has been replaced or repaired, the appropriate electrical safety checks must be made. Keep clear of the bed when it is being operated. Severe injury can result from crushing by moving parts. 4.1

Preliminary

a) Verify that no furniture or other obstruction can impede the movements of the bed. b) Connect the bed to the electrical supply. If necessary, reinstate all locked out functions. 4.2

Power Operated Functions

a) Check that each ACP operates all bed functions (height, backrest angle, leg elevation, kneebreak angle, tilt and Bio-Contour®). Verify satisfactory operation over the full range of movement as specified in Chapter 7, Technical Data. Verify that the actuators are de-energised when either Direction key is released or the limit of travel is reached. b) Check that both sets of patient controls operate the backrest, leg elevation and Bio-Contour® functions. c) Check that both sets of nurse controls operate the backrest, leg elevation, height and Bio-Contour® functions. d) Verify that the lockout function on the ACP disables the appropriate 4-2

746-559-2 05/10

functions on all of the control units. e) Check that both vascular and Fowler modes can be selected on the ACP, and that the lower leg section operates as expected in either mode. f) Raise the mattress platform to top height and raise the backrest and leg sections. Press and hold the CPR button and verify that the mattress platform returns to a flat, mid-height position. g) Check the operation of the underbed lights. h) Models 8001 and 8003: place an object on the base frame to obstruct the anti-entrapment beam. Verify that downward movement of the mattress platform is prevented and that the AES indicator on the ACP is lit red. Remove the obstruction. Check that the mattress platform will now move down and that the AES indicator is lit green. i) Models 8002 and 8003: place a compatible mattress on the bed. Ask a second person to lie on the bed and enable the bed exit detection system. Check that when the person gets off the bed, the alarm sounds and the bed exit indicator lights. 4.3

Battery Operation

Check the operation of the battery backup system as follows: a) Disconnect the bed from the electricity supply. b) Raise the mattress platform to maximum height, ignoring the battery warning tones. c) Raise the backrest and thigh sections as far as they will go. d) Press and hold the CPR key on the Attendant Control Panel (ACP) – the mattress platform will flatten and lower to a mid-height position. e) Lower the mattress platform to minimum (not extra low) height. f) Apply full head down tilt (Trendelenburg). g) Return the mattress platform to the horizontal position then apply full foot down tilt (reverse Trendelenburg). If the bed does not complete this test sequence, connect it to the electricity supply for at least eight hours to fully recharge the battery. Repeat steps a) to g); if the bed still fails to complete the test sequence, replace the backup battery.

Manual Functions

4.4.1 Brakes and Steering

Check the brakes for efficient operation. Apply the brakes and push the bed. None of the castors should rotate. Place the pedals in the “steer” position and verify that the tracking (steering) castor is engaged and does not swivel.

4.4.2 Split Safety Sides

Check the raising and lowering operation of each of the four safety side sections. Verify that the release and latching mechanisms are effective and that the sides are securely locked when raised. 4.4.3 Bed Extension

Check that the bed extension extends and retracts smoothly and easily. Make sure the catches operate easily and that the extension locks securely in both the normal and extended positions.

4.4.4 Bedstripper (linen shelf) 

Check that the bedstripper slides in and out easily. Test the latching mechanism by putting the bed into maximum foot down tilt – the bedstripper should remain in the stored position.

4.4.5 Emergency CPR Release

Raise the backrest to about 60°. Operate either CPR release handle and verify that the backrest descends to a horizontal position in a smooth, controlled manner. Check that both CPR release levers operate correctly.
