Instruction Manual for Care Bed Libra
Page 11
2.2.2 Safety Information for the Operator
Using this instruction manual, which must be provided with the bed, ensure
that every user is instructed in the safe operation of this bed before using it
for the first time.
Draw every user’s attention to the possible hazards that can arise if the bed
is improperly used. This applies in particular to the use of electrical drives
and safety sides.
In order to ensure permanently safe operation of this medical product with
no risk to occupants, users and third parties, observe your obligations in
accordance with MPBetreibV (Medical Devices Operator Ordinance).
If the bed is in long-term use, test the functions and check for visual
damages (see Chapter 6.2) after a reasonable period of time
(recommendation: annually).
Only permit persons who have been properly instructed to use this bed.
Make sure that substitute staff is also sufficiently well instructed in the safe
operation of the bed.
When other additional equipment (e.g. compressors for positioning systems,
etc.) is attached, ensure that all equipment is safely mounted and
functioning. Pay special attention to:
oSafe hook-up of all loose connector cables, tubing, etc.
oNo multiple socket outlets are located under the bed (fire hazard in the
presence of penetrating fluids).
oChapter 2.3.1of this instruction manual
In the case of ambiguity, consult the manufacturer of the additional
equipment or the Stiegelmeyer company.
Check that your staff is complying with the safety information.

Instruction Manual for Care Bed Libra
Page 12 -
2.2.3 Safety Information for the User
Route the cable for the transformer unit in such a way that it
cannot be pulled, driven over or damaged by moving parts
when the bed is operated.
At regular intervals, carry out a visual inspection of the
transformer unit cable to check for mechanical damage
(scuffing, exposed wires, kinks, pressure points, etc.). Such a
check should be performed:
oWhenever the transformer unit cable has been subjected to
any mechanical load, e.g. has been driven over by the bed
itself or by an equipment trolley, has been bent, stretched or
violently pulled due to the bed rolling away while still
plugged into the wall socket.
oWhenever the bed has been moved or relocated before
plugging it back into the transformer unit.
oRegularly by the user when the bed is in constant operation.
If any damage or malfunction is suspected
ounplug the transformer unit immediately from the power
supply.
oindicate clearly that the bed is “Out of Order”
oand take it out of service and
oreport it immediately to the operator responsible.
Check the strain relief of the mains cable regularly to ensure that
the screws are tight and secure.
When using external electrical components such as patient lifts,
reading lamps, or compressors for positioning systems, ensure
that all equipment mains cables will not become entangled or
damaged by the moving parts of the bed. This will prevent
potential hazards due to electric shocks, fire, etc.
Multiple sockets that are placed loosely on the ground should
not be used for connecting external electrical components.
Otherwise electrical risks might occur due to damaged mains
cables or penetrating liquid.
Before moving the bed, it is important to always unplug it from the
power supply. Store the transformer unit cable in the cable holder
provided to ensure that it will not fall off or trail on the floor.
(See here Chapter 4.4.1).
Ensure that the operator instructs you in the safe operation of
this bed.

Instruction Manual for Care Bed Libra
Page 13
Each time before using the bed, check that it is in perfect
working order to prevent unnecessary hazards for the patient
and delays to work procedures (see Chapter 3.1).
Make sure that the mattress base has travelled to its lowest
position before leaving the occupant unattended. In this way,
you greatly reduce the risk of the occupant injuring
himself/herself as a result of falling when getting in or out of
bed.
Place the handset out of reach (e.g. at the foot end) to protect
the occupant against accidental motor-driven adjustments or
lock the adjustment options of the handset if:
oThe occupant is unable to operate the bed safely or free
himself/herself from potentially dangerous positions.
oThe occupant could be at risk due to inadvertent adjustment
of the electric motors.
oThe safety sides are raised (risk of limbs being crushed or
trapped when adjusting the backrest or thigh rest).
oChildren are left unsupervised in the room with the bed.
The adjustments may then only be carried out by, or in the
presence of, an instructed person.
Ensure that no obstacles such as night tables, window sills,
sloping ceilings, floor cable ducts or chairs could impede
adjustments to the bed, to prevent damage to load-bearing
parts of the bed and to the obstacles.
When not in use, always stow the handset in such a way that it
can not fall onto the floor (hang it on the hook). Make sure that
the cable will not be damaged by moving parts of the bed.

2.3.4 Mechanical special equipment (optional)
–Combined safety sides (Mobivit): Combines the advantages of the familiar
full-length and split safety sides and provides maximum protection and the
largest amount of flexibility during use.
–Split MobiFlex safety sides on both sides (D): Our 2-stage, telescopic safety
sides can be adjusted across a range of settings to suit individual needs.
–Pivoting safety sides, both sides (A), covers 2/3 of the mattress base.
–Removable hygiene mattress base made of polypropylene is highly
breathable, thanks to its deep venting slits. It can be simply placed on top
of the mattress base and later removed. It is also easy to care for and can
be cleaned with conventional cleaning agents.
–Removable comfort mattress base is made of 50 separate spring elements.
These elements are designed to mould themselves closely to the shape of
the body and help to ventilate the mattress. Their flexibility also ensures that
the pressure is optimally distributed. The comfort mattress base also
significantly contributes to preventing decubitus.

Page 17
–Comfortable mechanical quick height adjustment for the backrest (CPR).
–Bed extension can be attached, lengthens the bed by approx. 20 cm,
respectively approx. 27 cm. Longer safety side bars and side panels are
necessary for this. If required, please consult our sales department (see
Chapter 6.4)
–Pillow storage integrated at the foot end; can be drawn out from under
the mattress base
–Wall deflection rollers effective in both horizontal and vertical directions
–Wall spacers, head end + sides; prevent the walls and other things in the
room from being damaged when adjusting the height of the bed.
–Infusions sleeve foot end, a sleeve for holding an infusion stand can be
mounted on the crossbar. More about this in Chapter 4.4.6.
2.3.5 Materials Used
For the most part, the bed was manufactured from steel profiles whose
surfaces were finished with a polyester powder coating or a metal coating of
zinc or chromium.
The headboards and safety sides are made of wood or wood products
whose surfaces have been finished. All surfaces are recognised as being safe
for contact with skin.

2.3.6 Structural Design
Mattress base
The mattress base is divided into a backrest, a fixed seat section, a thigh rest
and a lower leg rest. The rests are adjustable. The mattress base can be raised
and lowered horizontally or set to the reverse Trendelenburg position with the
foot end lowered (optional Trendelenburg position also available).
Chassis
The chassis is constructed from welded steel tubing with an optimised scissor
lift design and is equipped with four castors which can be locked in by axle at
the foot and head ends.
Safety sides
To protect the occupant from falling out, the bed has full-length safety sides
(2), or, optionally,
a combination safety side (Mobivit) (6),
a swivelling safety side (A),
a split safety side MobiFlex (D).
The safety sides can be raised, one after the other, from the lowered position
to protect the occupant and then lowered again.
Electric Drive System
The electrical drive system for this bed is single fault-safe and flame-retardant
(V0) and consists of:
an 'external' power supply. The transformer unit consists of: Power
converter and low-voltage connecting cable. The power converter
generates a safe, low voltage current which is not dangerous for
occupant or operator. The transformer unit provides protective low-
voltage power to the control for all drives (motors) through a connecting
cable.
the central control device. All drive motors and the handset, which work
on this safe low voltage are plugged into the central control unit.
the electric motors for the backrest and the thigh rest.
two electric motors for the mattress base height adjustment.
a handset with a flexible hook.
