XO FLEX unit without lifting mechanism for standalone 3rd party patient chair (XO-836)

1.1 UNIT STAND

• The unit stand is manufactured in steel and aluminum with:
  Service panels for easy access to XO Water disinfection, XO Suction disinfection and auxiliary connections
  Detachable aluminum side covers for easy service access
  Two buttons located on the top of the unit stand for patient activation of cuspidor flush and cup filler

1.2 WATER AND AIR SYSTEM

All incoming water is filtered (50 μm), eliminating particles from main water supply.
Incoming compressed air is filtered (5 μm).

A main water valve automatically switches water on/off when activating the main switch. A leakage sensor provides automatic shut-off of water supply if an internal water leak is detected.

An integrated water softener decarbonizes water for use in the XO unit and protects the internal components of the unit by reducing the limescale content. Furthermore, the taste of the water is improved by removing unpleasant odors and tastes, e.g. chlorine.

1.3 CUSPIDOR AND CUP FILLER

Detachable and thermodisinfectable cuspidor bowl in glass with gold trap. Swiveling stainless steel faucet with safety switch allowing easy removal of cuspidor bowl for cleaning. Detachable and thermodisinfectable cup holder and stainless steel faucet.

1.4 ARTICULATED BALANCED ARMS

Arms for instrument bridge, operating light and XO HD Display pivoting on one vertical column. Arms manufactured in aluminum and connected via slim joints with roller bearings. Adjustable and maintenance-free balance spring and friction brakes for smooth and effortless operation. Steel covers fitted with magnets.

1.5 INSTRUMENT BRIDGE

Fitted with up to six detachable unit instruments:

• The 3-/6-function syringe is placed to the left (near the dental assistant) or to the right (unit for left-handed dentists)
  All other unit instruments may be placed as required by the end users
  When ordering the unit please specify where the different instruments should be placed
  After delivery it is possible for a technician to rearrange the instruments on the bridge

The instrument bridge is supplied with:

• A detachable instrument pad
• A detachable bridge protection pad
• Two autoclavable handles
• A display
• A speaker with adjustable volume providing acoustic signals to the operator
• A programming button

The instrument bridge is prepared for a hand-instrument table.

1.6 INDIVIDUALLY BALANCED AND DETACHABLE UNIT INSTRUMENTS

Depending on the weight of the instrument, the instrument suspension is individually adjusted for optimal balance.

All unit instruments are fitted with a plug and may be attached/detached by the users for cleaning and disinfection – without using tools.

1.7 INSTRUMENT BRIDGE DISPLAY

At the front of the instrument bridge a display for monitoring instrument data is fitted. The light intensity of the display text field is adjustable.

The display consists of:

• One 8-digit text field: Indication of the maximum preset value of the primary instrument parameter (for example speed) when the instrument is lifted forward, but not activated – and the current value of this primary parameter when the instrument is activated
• Three green LEDs for indication of selected amount (three levels) of spray water or for spray water off
• One blue LED: Indication of spray air on/off
• One white LED: Automatic chip blow enabled/disabled

1.8 HANDS-FREE OPERATION

All functions of XO FLEX Unit, patient chair and instruments are controlled hands free using the foot control and/or chair base joystick.

1.9 FOOT CONTROL

The foot control is fitted with a pedal and joystick.
When all unit instruments are at rest the foot control manages functions related to the unit and chair etc.

When a unit instrument is lifted forward the foot control manages this active instrument.

The pedal can be activated in three directions (left, right and down).
The joystick can be activated in four directions (north, east, west and south).

In addition, the foot control is equipped with two activation buttons and a hoop in stainless steel.

1.10 CONTROL OF MICROMOTOR

Speed control method: Variable.
Selection between three (maximum) speed levels in the range 100 – 40.000 RPM + 20%.

1.11 ELECTRONIC CONTROL OF “AIR” (TURBINE OR AIR SCALER, FOR EXAMPLE) INSTRUMENT

Speed (power) control method: One-step.
Selection between three speed/power levels.

1.12 ELECTRONIC CONTROL OF SPRAY WATER AND AIR

The amount of spray (irrigation) water and air is controlled electronically using proportional solenoid valves.

The spray water may be adjusted in the range: 10 – 70 ml/min ± 20% depending on the dimensions of the spray pipes in the attached instruments.

Spray air can be set between 0 – 100% of maximum.

1.13 AUTOMATIC CHIP BLOW

Short blast of high-pressure chip air each time an instrument with spray water stops. Keeps the preparation dry and helps the operator focus on the work task.

1.14 CONTROL OF SCALER

Control method: One-step.
With selection between three power levels.
Irrigation water for scalers may be adjusted in the range: 10 – 90 ml/min ± 20%.
Selection between three irrigation water levels (and no irrigation).

1.15 CHAIR BASE JOYSTICK

Left-handed configuration is obtained by fitting the:

• 3- or 6-function syringe on the right side of the instrument bridge
• The XO Ambidex suction hose holder enables you to work right-handed, left-handed, SOLO, or in DUO

1.20 XO WATER DISINFECTION

• XO Water disinfection continuously dispenses a solution of non-toxic disinfectant containing hydrogen peroxide to the procedural water. The disinfectant is proven to keep the number of microorganisms in the unit at a level suitable for drinking water and it hinders limescale from forming by binding the calcium carbonate.
• XO Water disinfection is supplied with a disinfection instrument holder.
• The users are notified on the instrument bridge display when the level of disinfectant is low.
• The cartridge holder is accessible from the outside through a service panel and allows for quick replacement of disinfection cartridges by the users.
• Two types of disinfection routines are available:
• Overnight disinfection:
  • At the end of the workday the water container and unit’s waterlines are emptied
  • At the beginning of the next workday the water container is filled and the unit water lines are flushed with disinfectant
• Intensive disinfection for use after weekends, holidays, or longer periods where the unit has not been used:
  • The water tank is emptied
  • The water tank is filled again using a double dose of disinfectant
  • The unit water lines are flushed with a double dose of disinfectant

For details concerning XO Water disinfection, cartridges see here.

Please note: XO Water disinfection cartridges must be ordered separately.

1.21 BACKFLOW PREVENTION

The backflow prevention provides a vertical air gap of 20 mm for preventing procedural water from flowing back into the municipal water supply system.

It contains a water tank with a capacity of approx. 1 liter that provides pressure to the water that has passed through the air gap. The water tank is filled when there is no demand for procedural water.

A suitable method for preventing contaminants from flowing back into the municipal water supply is required by law within the EU. Without the backflow module the XO unit does not fulfill the requirements of ISO 7492-2 and EN 1717

1.22 ASEPSIS, CROSS INFECTION, CLEANING AND ENVIRONMENTAL CONTROL FEATURES

XO FLEX is designed with smooth and easy-to-clean surfaces.

Metal parts of XO FLEX are painted using an antimicrobial powder coat. A combination of agents with nanoscale silver gives a long-term protection against formation of bacteria and fungi on the surfaces.

The unit is supplied with autoclavable handles, suction nozzles, cover for instrument holder, and XO Patient tray.

• Other XO FLEX features that enhance asepsis and reduce environmental footprint:
  • Hands-free user interface
  • Automatic chip blow
  • XO Water disinfection
