The power driven functions of height, backrest angle and leg elevation are operated by simple push button controls. The push button handset may be used by the caregiver or patient. A second handset, accessible only to the caregiver, incorporates additional push buttons for two-way tilt control and CPR emergency settings. The bed also has an attendant control panel (ACP), by means of which the power driven functions can be individually disabled. Operation of the bed by the patient is thus at the discretion of the caregiver. 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 a mains operated d.c. power supply with emergency battery back up.

746-173-CA-3

In-Bed Weighing (Contoura C1080 only)

The in-bed weighing system is designed to be used for monitoring changes in a patient’s weight over a period of time deemed appropriate by clinical staff. This may be used, in association with other clinical findings, to monitor the overall progress of the patient. To gain a true representation of the change in a patient’s weight, urine bags and drainage bags should be emptied before the reading is taken.

Contraindications

Do not exceed the safe working load of 1100 lbs. (500kg) for the combined patient, mattress and accessories.

When using powered mattress replacements, e.g. BariBreeze, do not exceed the safe working load stated by the mattress manufacturer.

Model 1080

When the bed is in the area where it is to be used, release the transport locking screws by turning them fully anti-clockwise. These are four, hand operated turnscrews which are accessible on the base.

Caution The transport locking screws must always be firmly locked when the bed is moved except for short distances over smooth surfaces. BariBreeze Mattress Replacement System Contoura C1000 and C1080 beds are suitable for use with the ArjoHuntleigh BariBreeze mattress replacement system, model number 647311.

WARNING Read the Instructions for Use supplied with the BariBreeze mattress before attempting to install or use it. Make sure that the mattress tubes and mains cable do not become entangled with moving parts of the bed. Before using the BariBreeze mattress “patient turn” feature: • Raise the siderails – they can be upright or inclined outwards as required • Make sure that the patient cannot roll off the mattress when the bed is profiled. The degree of turn and profiling that can be used safely will depend on the size and condition of the patient.



The Contoura C1080 bed can also be used with a standard mattress, model 450PM206/092. Details will be provided on request.

4. Operation • Always use a mattress of the correct size and type. Suitable mattresses are available from ArjoHuntleigh.

Safety

• When the bed is operated, check that no obstacles such as bedside furniture are in its path. Also make sure that the patient’s and caregivers’ limbs are not trapped. • Always apply the brakes when the bed is stationary. • Lower the bed to minimum height and raise the siderails when the patient is left unattended. • Keep these instructions handy for reference.

WARNING The bed is very heavy and at least two people are needed to move it. Use extra caution when moving on an incline. Brakes and Steering

At the foot of the bed is a pair of linked brake pedals that operate on all four castors. When the pedals are in the middle position, the brakes are free and all four castors are able to rotate and swivel. When the pedals are pushed down, the brakes are applied on all four castors. When the pedals are raised, both head end castors are engaged so that they cannot swivel. Always engage both castors in line and trailing. The bed can then be steered by pushing from the foot end.

Backrest Adjustment

The angle of the backrest is adjusted by means of push buttons. Refer to Power Operation later in this section.

Leg Elevation

As the legs are raised, by increasing the angle of the thigh section, the kneebreak angle will increase correspondingly. The elevation of the leg section is adjusted by means of push buttons. Refer to Power Operation later in this section.

Height Adjustment

The height of the mattress platform is adjusted by means of push buttons. Refer to Power Operation later in this section.

Tilt Adjustment

The angle of tilt is adjusted by means of push buttons on the caregiver handset. Refer to Power Operation later in this section.

Power Operation General

The bed is provided with power driven adjustment of backrest angle, leg elevation, bed height and tilt angle. The functions are operated from a push button handset, which is connected to the bed by an extendable, flexible cable. When a push button is pressed, the appropriate bed function will operate until the push button is released or the limit of travel is reached. The Autocontour button operates both backrest and leg elevation simultaneously. The backrest, leg and height controls are duplicated on a second handset, accessible only to the caregiver, which has additional push buttons for the control of tilt angle and emergency CPR configuration. The caregiver handset is stored at the foot end of the bed.

Backrest Leg elevation Height Auto-contour

Patient control handset By using the Attendant Control Panel (ACP), the Control Inhibit (using the ACP) caregiver has the discretion to disable the push button controls and thus limit or prevent operation of the bed by the patient. Pull out the sliding tray beneath the foot end of the mattress platform. This gives access to both the ACP and the user interface module for the weighing system if fitted. The caregiver handset is also stored on this tray. Use of the weighing system is described in Section 5. On the ACP is a rotary ‘lock-out’ switch for each bed function. To prevent the patient from making an adjustment, disable that particular bed function by turning the lock-out switch so that the pointer is horizontal. In this condition the selected push buttons are disabled on both the patient handset and the caregiver handset. Because the bed height and tilt angles are determined by the same two actuators, both these functions are disabled by the same lock-out switch.

Tilt Angle Control

The tilt angle can only be controlled from the caregiver handset When reverting from a tilt condition, the bed will automatically stop in the horizontal position for two or three seconds.

CPR Emergency

There is a CPR button on the caregiver handset. Press and hold this button to automatically return the bed to a flat, horizontal, low height condition.

WARNING Before using the CPR button, ensure that all lock out switches on the ACP are in the vertical, unlocked position. Calibration Errors

If a bleeping sound is heard when operating the push buttons and the function is inoperative, this indicates an actuator calibration error. Contact the ArjoHuntleigh service department.

Batteries

The emergency back-up battery is automatically switched on if the bed is disconnected from the electrical supply. Battery life is limited and is intended for emergency use only. To ensure that batteries are kept in a fully charged condition, the bed must be connected to the electrical supply at all times during normal use. If, when the bed is operated using the batteries, a bleeping sound is heard, this indicates a low charge condition. The bed should be reconnected to the electrical supply, for a minimum of 24 hours in order to recharge the batteries. The battery charge indicator on the ACP illuminates when the batteries are being charged.

5. Patient Weighing System (Model C1080) General

Four load cells are installed in the bed frame. The electrical output signals from the load cells are integrated in a load converter, which provides a single output to the user interface. Separate displays are provided for patient weight and patient weight change.

Accuracy

The weighing system is very sensitive and will be affected by a number of outside influences. It is therefore important that the following criteria are observed. a) The bed must be installed on a flat and level floor. b) The transport screws must be fully disengaged prior to use. c) The bed should be positioned clear of obstructions such as walls, furniture, trailing leads or curtains. d) The weighing system should be used within the normal operating ambient temperature range of 50°F to 104°F (10°C to 40°C). e) For best results, the patient should be positioned approximately centrally on the bed. f) The weighing system is capable of detecting relatively small movements of the patient. It is therefore necessary for patient movement to be minimized during the few seconds required to obtain a stabilized reading and that the operators / caregivers stand clear of the bed during this time. g) When weighing, the handsets must be replaced in position on the platform.

User Interface Module (UIM)

Lift and pull out the sliding tray beneath the foot end of the mattress platform. Open the lid of the UIM (right hand side).

Pull out sliding tray Operation

Operation of the system is described in the following paragraphs. The way the features are used varies in accordance with the situation viz.: Patient already on the bed. Enter the previously known patient weight on the top display. Enter the previously known patient weight change on the bottom display. (If not known, zero the bottom display). The indicator will now display patient weight and weight change as patient weight varies, starting at the values entered Empty bed. Zero the top display. Place patient on the bed. Top display reads patient weight. Zero the bottom display. As patient weight varies, the change is shown on the bottom display

System Stable Indicator

After pressing buttons, a small delay occurs before the display responds. The System Stable indicator (F) will illuminate to show that display readings are valid.
