Introduction
The Vacuum 660 unit provides a convenient form of electrode application for interferential therapy. The cup electrodes with their sponge inserts are held in place by a partial vacuum. Both the vacuum and the electrical connection to each cup are provided by a single lead.
This method of electrode application is particularly suitable when treating relatively flat, smooth areas of the body such as the back where the cups may be attached quickly and easily. Also, this method is useful when treating relatively immobile patients, as the electrodes may be applied with the patient in a comfortable position without having to be moved for the application of hook and loop bandages.
With the Vacuum 660 unit, the vacuum may be set to a convenient and comfortable level with a front panel control.
Connection to an interferential unit is made from the socket on the front of the Vacuum 660 unit, using the link lead provided. Two or four pole electrode applications may be used.
A pulsed vacuum mode is provided to further reduce the likelihood of bruising due to the vacuum. Two pulse rates are provided.
Contraindications
Vacuum electrodes should not be used on elderly patients with thin papery skin leading to contact difficulty and bruising. Vacuum electrodes are not suitable for patients who are taking steroids because of the likelihood of bruising.
Environmental
At the end its life, the Vacuum 660 should not be disposed of as unsorted
general waste. Advice on appropriate disposal is available from EMS Physio
Ltd. (contact details on page 16).

Installation
Upon receipt, check for any visible damage which may have occurred in transit. If any signs of damage are found then retain all packing material and inform the carrier and the Company or its agent from whom the unit was purchased within two working days.
If not already fitted, connect a suitable plug to the mains cable of your current Primo 18VDC adaptor. The plug must have provision for an EARTH (GROUND) connection. The mains cable has the following colour code: BROWN is LIVE (LINE), BLUE is NEUTRAL and GREEN/YELLOW is EARTH.
The Vacuum 660 unit must only be connected to an EMS 18VDC adaptor with a protective earth conductor (SLA9000). If the integrity of the earth connection is in doubt, do not connect the 18VDC adaptor to the mains supply.
The Vacuum 660 is designed to sit under the Primo unit with which it is being used.
At the rear of the Vacuum:
-
Connect the Primo 18VDC power adaptor to the 18VDC `IN’ socket.
-
Connect the Power Link lead from the 18VDC `OUT’ socket to the power socket on the stimulation device.
At the front of the Vacuum: -
Connect the output socket of the stimulator unit to the input socket on the vacuum using the appropriate link lead.
-
The Vacuum 660 unit is supplied with a set of four suction leads and four 60mm auto seal suction cups with sponges. Connect one end of each suction lead to the vacuum outlets on the front of the unit. The RED leads are for channel A and the BLACK leads for channel B. Insert the other end of each lead into the connector at the rear of the suction cups. The connectors at each end of the suction leads are a simple push fit and provide both vacuum and electrical connection to the cups.
Operation of the unit in close proximity (less than 1 metre) to shortwave therapy equipment or radio-frequency mobile communication equipment could result in the stimulation output being affected.
View of Complete System
The Vacuum 660 is designed to sit under the Primo unit with which it is being used. The output socket of the stimulator is connected to the input of the vacuum unit with the link lead provided. It is also designed to sit on the EMS trolley (EMS158) which is optional.
Operating Instructions
As described in the `Installation’ section on page 12, connect the Primo Power supply and Power Link lead as described, to the Vacuum and Stimulator units. Make sure that the Vacuum 660 input is connected to the output socket of the stimulator using the appropriate Link lead.
Insert the suction leads into the outlets on the front of the unit and the suction cups also described in the `Installation’ section of this manual.
Switch on the stimulator being used with the Vacuum 660 and select the required treatment according to its operating instructions. Do not energise the output of the stimulator unit at this time.
Wet the suction cup sponge inserts with water and squeeze until they are wet but not dripping. In soft water areas it may be necessary to add a small amount of sodium bicarbonate to the water to ensure low contact impedance.
Insert the sponges into the cups ready for application to the patient.
To turn the Vacuum unit on’, rotate the front dial on the unit clockwise until it clicks. The unit will do a quick self-test and the three green LEDs will begin toblink’ – this is a reminder to check that the water trap at the
rear of the unit is empty before starting any treatment. If water is present,
see below.
To empty the water trap – twist the clear collection chamber to the left (from L to O) and the chamber will release, pull the chamber down and empty it. Reverse the procedure to lock the chamber back into place.
Confirm the water trap is empty by pressing and holding the `ENTER’ button for a second.
The unit will start in continuous mode – place the cups over the patient and increase the rotary dial till the LED colour turns blue.
When the suction cups have been attached satisfactorily to the patient the vacuum may now be reduced to a comfortable level using the vacuum control. You can also now select any other mode that is required by repeatedly pressing the `ENTER/MODE’ button – Continuous Pulse I Pulse II and back again to Continuous.
Having successfully applied the suction cups and set the vacuum mode and level, energise the output of the stimulator.
If the suction cups become detached during treatment the stimulator output must be de-energised before attempting to reconnect the cup electrodes. With the Multidyne 970 and Interferential 960 units set to constant current, the output will normally be terminated when the cups become detached and an alarm will sound. In constant voltage modes the output must be reduced to zero manually.
At the end of treatment, return the output control of the stimulator to its off position before removing the suction cups. With the Multidyne 970 and Interferential 960 units the output is automatically set to zero at the end of the treatment time.
To remove the suction cups, turn the Vacuum rotary dial anticlockwise to the `off’ position. The cups will detach themselves as the vacuum under the cups is released.
Note that the contact area of the 60mm suction cups is approximately 25cm2. The maximum recommended current density is 2 mA/cm2 and hence the current applied with the suction cups should not exceed 50 mA rms. When using interferential therapy units this corresponds to 70mA peak for the 60mm cups.
Excess water from the sponges is captured by the water trap on the rear of the Vacuum 660. It is recommended that the water trap is emptied between treatments. See previous page (14) for instructions on emptying the water trap.
WARNING - Failure to frequently empty the water trap will result in excess water overflowing from the tube connection port on the rear of the unit. To prevent any spillages, connect the supplied tubing into this port and drain the excess water into any external receptacle. Always empty the water trap after any treatment.
Maintenance
The suction cups and sponges may be disinfected using a 70% v/v aqueous solution of isopropyl alcohol. They are NOT suitable for steam sterilisation or treatment with disinfectants containing sodium hypochlorite.
N.B. Isopropyl alcohol is flammable and should be kept away from naked flames. Isopropyl alcohol must not be brought into contact with eyes or mouth.
The Vacuum 660 may be cleaned by wiping over with a clean damp cloth. The use of abrasive materials and cleaning solvents should be avoided.
Regularly (at least monthly) inspect the suction leads, cups, cables and connectors for damage.
The Vacuum 660 should be serviced at least annually by qualified personnel.
If, during set-up, the front panel LEDs all begin to flash in unison, this is an error message implying that the internal pressure sensor has detected an out of range value. Switch the unit off, check that the leads and cups are correctly connected and not obstructed and re-start the unit. If this error message persists, contact qualified service personnel.
There are no user serviceable parts inside the unit and it should not be opened.
Full servicing instructions are available on request.
