2. Clinical Applications Area of Use

General medicine, general and specialist surgery, care of the elderly, oncology.

Indications Non-electric Models

The bed is appropriate for medium to high dependency patients who would benefit from a profiling bed for comfort and / or management of their clinical condition. The profiling allows appropriate positioning of the patient with minimal physical handling, minimising stress and discomfort to the patient.

Electric Models

The bed is appropriate for medium to high dependency patients who would benefit from a profiling bed for comfort and / or management of their clinical condition. The electrical profiling allows appropriate positioning of the patient with minimal physical handling, minimising stress and discomfort to the patient and reducing moving and handling risks to staff. Patients with a moderate amount of independence can, at the nurses’ discretion, use the controls to adjust their own position.

Any Model

The optional x-ray translucent backrest and cassette tray enables chest x-rays to be taken without moving the patient from the bed to a trolley. This is particularly useful for patients who require chest x-rays but whose condition requires that they are moved as little as possible.

Contraindications

The maximum safe working load for the bed is 180 kg. The bed is not appropriate for any patient whose condition requires the bed to be tilted more than 12° head down or 6° foot down. It is not appropriate for heavy patients where tilting using the gas spring mechanism would pose a moving and handling risk to staff. The non-electric bed is not appropriate for heavy patients where altering the position or height of the patient would pose a moving or handling risk to staff.

3. Installation Electrical Models Unwind the mains supply cable from the cable tidy at the head of the bed and connect it to a suitable socket outlet.

+

A two-pin to three-pin mains safety adaptor (Part No. S5761) is supplied for UK use. If the bed is accidentally moved whilst connected to the mains supply, the lead and adaptor are designed to separate, preventing damage to the 3 pin plug or socket. WARNING

Do not attempt to insert the two-pin mains connector directly into a 13 amp mains outlet. Make sure that the mains cable is not stretched when connected. Make sure that the handset and mains cables cannot become entangled with moving parts of the bed.

Caution When the bed is to be moved, disconnect the mains cable from the socket outlet and store the cable on the cable tidy at the head of the bed. Always remove the cable from the cable tidy when it is connected to the power supply. An equipotential terminal in accordance with the requirements of IEC 601-1 (EN 60601-1) is provided on the mattress platform frame at the head end of the bed.

Always use a mattress of the correct size and type. A range of suitable mattresses and pressure relieving mattresses is available from Huntleigh Nesbit Evans. When the bed is operated, ensure that no obstacles such as bed-side furniture are in its path. Before operating the bed, ensure that the patient is positioned correctly to avoid entrapment or imbalance. Do not expose the equipment, especially the mattress, to naked flames such as cigarettes etc. Always apply the brakes when the bed is stationary. Keep these instructions handy for reference.

Brakes and Steering At the foot of the bed is a pair of linked brake pedals, which operate all the castors.

All Models

When the pedal is raised it engages one head end castor so that it cannot swivel. The bed can then be steered by pushing or pulling from the foot end.

5. Cleaning WARNINGS Before cleaning an electrical bed, disconnect the bed from the mains power supply by removing the plug from the socket outlet. 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 a 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 used by a client with a known infection, clean afterwards with NaDCC (i.e. 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 hypocarbonate or phenol based cleaning agents. Do not use abrasive compounds or pads.

17

6. Maintenance The following preventive maintenance procedures should be carried out at intervals of six months. WARNING Before commencing any maintenance activity on an electrical bed, disconnect the bed from the power supply. Electrical equipment can be hazardous if misused. The control box covers should only be removed by an approved Huntleigh Nesbit Evans service technician. Avoid skin contact with lubricants. Rubber gloves and protective clothing should be worn when carrying out maintenance work. General

Examine the bed for obvious signs of damage. Make sure that all nuts, bolts and other fastenings are tight and not missing. On power operated beds examine the flexible cables for cuts, abrasions, kinking or other deterioration. Ensure that the power supply connector plug is not damaged. If appropriate, check that the adaptor plug fuse is of the correct type (BS 1362 5amp). If the power supply cable or plug are damaged, they must be replaced as a complete assembly by an approved Huntleigh Nesbit Evans service technician.

Lifting mechanism Non-electric Models

Check the hydraulic system for leaks. If leaks are found, contact Huntleigh Nesbit Evans Ltd. Check the operation of the lifting mechanism. A steady firm resistance should be felt over the full stroke of the pedal. If the pedal pressure is variable or yielding, this may indicate the presence of air in the hydraulic system and can be remedied as follows: Raise the bed to full height and continue pumping for four or five pedal strokes then lower the bed fully. Repeat this action two or three times. If firm and steady pedal operation is not restored, contact Huntleigh Nesbit Evans Ltd.

18

Tilt Assembly

The two rods which enter the tilt-box should be cleaned and lightly regreased with Shell Rhodina LF grease 2. If the tilt-box fails to unlock correctly, this may be because the release cable has stretched. To remedy this, adjust the two nuts which hold the cable close to the tilt handle. Loosen the nuts and adjust them to take up the slack. Do not overtighten the cable. When operation is satisfactory, re-tighten the nuts. Every twelve months the tilt box locking mechanism should be checked for wear as follows: Tilt the mattress platform to approximately 5° head down. At the foot end, hold each corner of the mattress frame in turn and apply force in both upward and downward directions. The lockbox should lock effectively in both directions. If the locking mechanism slips, first make sure that the cable is not over adjusted. If slippage still occurs the locking plates may be worn. Contact Huntleigh Nesbit Evans Ltd.

Castors and Brakes All Models

Check the brakes for efficient operation. Apply the brakes and push the bed. If any of the three braking castors rotate, the brake is not fully effective. Check the steering lock for efficient operation. If brakes or steering lock are not fully effective, contact Huntleigh Nesbit Evans Ltd.

19

Batteries Electric Models

The condition of the batteries should be checked every six months using the following procedure. 1. Ensure that the bed has been connected to the mains supply for 24 hours. 2. Disconnect the bed from the mains supply. 3. Apply a load of 80kg (12st person) to the mattress platform. 4. Raise and lower the mattress platform, from minimum to maximum height, three times. 5. If the bed does not operate satisfactorily in step 4, perform steps 1 to 4 again. If the bed again fails to operate satisfactorily the batteries should be replaced. Contact Huntleigh Nesbit Evans Ltd.

Lifting Pole

Examine the handle and strap for signs of damage, fraying or loose stitching. Replace the strap and handle if found.

For full servicing, repairs or other maintenance on the bed, contact Huntleigh Nesbit Evans Ltd, service department.
