Figure 1-1 Enterprise™ 5000B 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 patient control handset is attached to a flexible cable and may be positioned on either side of the bed. The patient’s controls adjust backrest angle and leg elevation, including Bio-Contour®. The bed has an attendant control panel (ACP), attached to flexible cable and located at the foot end of the bed, 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 underbed lights 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. Model 5001 beds are equipped with an anti entrapment system (AES), which uses an infra red transmitter positioned above each castor to generate an invisible beam around the perimeter of the bed. If this beam is interrupted, e.g. by a carer’s foot or patient’s limb, downward movement of the mattress platform is prevented until the obstruction is removed.

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 electricity 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 Huntleigh Healthcare. Disposal of product and components should be compliant with local regulations.

WARNING Before starting any maintenance activity, disconnect the bed from the electrical 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 electrical supply plug and cable for damage. If either the plug or cable is damaged, both must be replaced as a complete assembly. Under no circumstances should the integral 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 requires replacement. 3.3

Backup Battery

If a beeping sound is heard when the bed is operated from the battery, this indicates a low charge condition. Connect the bed to the electricity supply for a minimum of 24 hours, in order to recharge the batteries. 3-2

746-446-7 04/08

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 bed user manual, Huntleigh publication number 746-445. 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 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

Power Operated Functions

a) Check that the 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 the patient handset operates the backrest, leg elevation and Bio-Contour® functions. c) Verify that the lockout function on the ACP disables the appropriate functions on both the ACP and patient handset. d) Check that both vascular and Fowler modes can be selected on the ACP, and that the lower leg (calf) section moves as expected in either mode. e) Use the ACP to raise the backrest and leg sections, and raise the mattress platform to near top height. Press and hold the CPR button and verify that the mattress platform returns to a flat, medium height condition. f) Check the operation of the underbed lights. g) 5001 series only: Place an obstruction on the base section of the bed to 4-1

746-446-7 04/08

block the anti-entrapment beam. Check that the AES LED on the ACP lights red and downward movement of the mattress platform is prevented. Remove the obstruction and verify that the AES LED is now green and normal movement of the mattress platform is restored. 4.2

Battery Operation

a) Disconnect the bed from the electricity supply. b) Check the functions of bed height, backrest angle, leg elevation and tilt. While operating the bed, check that an intermittent beep-beep sound is heard. 4.3

Manual Functions

4.3.1 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. 4.3.2 Folding Safety Sides

Check operation of both safety sides. Verify that the release and latching mechanisms are effective and that the sides are securely locked when raised. 4.3.3 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. 4.3.4 Bedstripper 

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. 4.3.5 Emergency CPR Release

Use the patient handset to raise the backrest to about 60°. Operate either CPR release handle and verify that the backrest descends to a horizontal 4-2

SERVICING INSTRUCTIONS WARNING

Before starting any service or maintenance procedures, ensure that the equipment has been adequately decontaminated. Avoid skin contact with lubricants. Rubber gloves and protective clothing should be worn when carrying out maintenance work. The bed and its sub-assemblies are heavy and could cause serious injury or death by crushing. When working beneath the mattress platform, the equipment must be properly supported with suitable lifting devices, blocks or stands. Use only replacement parts that are approved by Huntleigh Healthcare. 6.1

General

The servicing procedures and data given in this section include instructions for: • Replacement of specific components and sub-assemblies • Dismantling and assembly of the main structure • Restoration of paint finish Minor procedures considered to be self-evident have not been included. Do not disassemble further than is necessary to replace a defective item. Remove old Loctite® and other adhesives from components before reassembly. Apply Loctite® adhesive where specified in Appendix A. Before applying Loctite®, clean and degrease parts using a suitable volatile solvent, e.g. methylated spirits. The hinges between the various parts of the bed incorporate self-lubricating conductive plastic bushes and do not require lubrication. Throughout this section, numbers given in brackets refer to the Assembly Spares Manual drawing sheet number and item number for the part. Thus (03-5) represents Item 5 on Sheet 03. To facilitate access for carrying out servicing procedures, remove the mattress platform sheets and head/foot end panels from the bed. 6-1

746-446-7 04/08



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

Before returning the equipment to use following repair or servicing: • Carry out a visual inspection for signs of damage, paying particular attention to cables and paintwork. • Perform a serviceability test as described in Chapter 4. • Clean the equipment as described in Chapter 2. Caution After replacing any cable or actuator, check that none of the cables are kinked, strained or pinched. Adjust the cables to remove any slack that could become entangled in the bed mechanism. Verify that these conditions are maintained over the full range of movement of the bed sections. 6.1.1 Actuator Cable Clips
