Part 11: INSTALLATION. Physical and functional location of the equipment.

Use environment:

Don’t use the equipment neither in bleakness, nor in presence of inflammable gases (p.e. anesthetics).

Don't use the system when some of its cables cross doors or windows that can close, through corridors or simply in case of the possibility that any person can trip with them.

Don't use the system in places where children or visitors have access to it.

1. Characteristic of the ROOM

1.1. It should be avoided the synthetic carpets to prevent electrostatic discharges.

1.2. Caution should be had, especially in places with nylon carpets, and/or with very low ambient humidity, in touching the electrodes or connected sensors to the Neurotrace. It is convenient always to touch previously some connected element to the ground, to discharge the electrostatic discharges.

It is also a factor of the electrostatic discharges increase the use of nylon overcoats, specially associated to another dress of wool y/o cotton.

1.3. The place should be aired (ventilated) and with sources of heat generation t

(Stoves) far away.

If the ambient temperature is inside the specified range, it doesn't alter the security of the product, but if the patient being studied presents for this reason an increase of the perspiration, it should decrease the anbient temperature until perspiration is not present, since it usually generate noises of low frequency in the data, comparable to base line movements.

1.4. To avoid all type of illumination with fluorescent tubes, when these are not under

good conditions.


1.5. The ROOM should be far from intense electromagnetic fields (i.e. electrotherapy rooms, computed tomographs, x ray , etc.).

The intense magnetic fields can cause the presence in screen of signs of their same generation frequency. The magnetic fields when meeting with the electrodes and sensors cables generate an electric current interpreted as noise. It should be avoided to work near very powerful equipment transformers, electric motors, illumination fluorescent reactancies etc.

The near electric fields can cause noise of their same frequency during the data acquisition. It should be avoided to work near electric cables, walls that conduct especially if the same ones can have flaws of insulation. The patient should not take contact with the walls while making the study.

locate PC monitors far from the headbox, electrodes and sensors cables, and from the patient. locate the Neurotrace source far from the headbox, electrodes and sensors cables, and from the patient.

1.6. If there were metallic elements such as stretchers, bookcases, etc., it is

recommended to put them a good ground connexion.

1.7. The ambient should be with delicate illumination and silent.

2. Recommendations on the PATIENT

Not use Electric Stimulator over implanted patients with electronics devices (B.E. Heart stepper).

Not use Electric Stimulator over patient torax

Not to place the electrodes has more than enough ulcerated skin and/or burnt.

2.1. request the patient that washes the head with products free of detergents, (as being shampoo and creams to rinse) it is recommended to use neuter soap.

2.2. explain to the patient the nature of the test to carry out.

2.3. the patient should be located in comfortable position, to avoid the muscular groups

contract that distort the layout.

2.4. clean with alcohol or similar the hairy leather, previous to place the electrodes, in cases of intense dandruff, use cleaning cream


2.5. use PAST or CONDUCTIVE GEL to stick the electrodes.

2.6. Special ATTENTION should be paid to the electrodes placement because of this it

depends to achieve a good signal.

2.7. the patient should be connected with electrodes to the ground and to the system reference

3. Connection to other equipments:

BIO-PC system can be connected to other products or sanitary equipments, such as phtostimulators, Audiostimulators, etc. The equipment used should manage signs compatible TTL.

BIO-PC system can be connected to other products or sanitary equipments that have analogical output, such as Oximetry / pH / Pressure CPAP / Other signs of AD, inside the specified range. The only inputs enabled for such case, are in the system headbox , identified as EXT1 and EXT2.

The computer, devices and/or equipment to be used together with the BIO-PC system will be normalized according to EN60601-1.

The system possesses sensitive parts to the electrostatic discharges (ESD), to avoid risks, the system should be connected as it is described in this manual, previously to turn on the feeding source provided with the equipment and the computer where the system will work.

The equipment won't be used jointly with heart Desfibrillator or Electrobisturí


4. Working Conditions:

Verify the range selection of input line , according to the selection key in the rear panel of the BIO-PC.

Original parts, accessories and interconnection cables provided by AKONIC S.A. or its authorized local representative should only be used. Otherwise, it can put in risk the security and efficiency characteristics of the system.

It should verify the state of the accessories and the patient's cables regularly. This verification can be carried out verifying in visual way simulating the use of the accessories, or for its local representative. In electrodes it can verify the continuity of the electrode with a multímeter.

Always use the connection of functional ground not only to obtain a good signal, but also for the eventual risk of electric crash to the operator and/or patient . Not using it is a serious violation to the practices of electric security.

5. Security ground setting conditions:

The Ground cable of the equipment should be used whose voltage regarding neuter line pole doesn't overcome 5 Volts of AC. The verification procedure consists of the following steps:

Mensuration with a tester of the voltage of feeding line.

Mensuration with a tester between the ground and each one of the poles of the feeding line.

The mensuration between the ground and the neuter line pole (identified to give the less lecture) is recommended doesn't overcome the value given previously (5 Volts).
