GENERAL DESCRIPTION
1 General Description
1.1 Purpose of Application
BIOSET 3700 is a 6-channel electrocardiograph.
The unit can be optionally equipped with accumulator, 1 V outlets and an additional computer interface.
BIOSET 3700 is intended for ECG recording under the conditions of ambulant practice and clinical routine.
Owing to its small size, low weight and possibility of battery operation, it is suited for home visits and
emergency medicine, too.
1.2 Unit Design
BIOSET 3700 is a compact unit with the upper side slightly inclined to the user.
The casing consists of two plastic shells with easy-to-clean surface.
A handle at the unit’s left hand side permits convenient carrying.
Main components:
Upper casing part including
- signal board
- keyboard
- display
- recoding unit
Lower casing part including
- power supply
1-1
PATIENT´S AND UNIT´S SAFETY
2 Patient’s and Unit’s Safety
The unit is in conformity with the Medical Products Act (MPG) and the "Guideline 93/42/EC on
medical products" and the meets thus the safety requirements as per EN 60 601-1 (IEC 601-1) as well
as the EMC requirements as per EN 60-601-1-2 (EMC act).
With reference to the above guideline, the unit is categorised as risk class IIa.
In order to protect both patient and personnel, the instrument must be earthed. This unit complies with the
protection class I. This way, it will be earthed through the protective conductor. Any usage of mainsconnecting facilities which can cause the protective conductor to be interrupted is forbidden.
For establishing the connection to the room’ s central earth connection point, use the earth clamp. If this
earth clamp is to be applied on thin-walled electric installation materials, proceed cautiously because of
destruction hazard.
If that patient cable designed for due application is used, the unit will work as a defibrillation-proof one.
Patient, unit, and bed must not be touched during defibrillation.
Conducting parts of electrodes and electrode connectors must neither touch different conducting parts
nor have earth contact.
The unit should be operated inside rooms protected against vibrations and corrosive gases. The unit w orks
at ambient temperatures of 10 °C ... 35 °C.
For a safe operation to obtain, keep the unit free from condensation water. In order to prevent that, make
the unit acclimate after relevant temperature alterations.
Once temperature and atmospheric humidity have compensated, the unit can be operated.
The unit is not intended to be run inside explosion-hazardous locations. If inflammable gas mixtures (e.g.
ether) are present, explosion hazard cannot be excluded.
If the instrument documentation does not suggest, whether or not some combination or coupling of the unit
with other devices is possible without hazards, the user has to make sure - by questioning the manufacturers/
suppliers concerned or by inquiring an expert - that the necessary safety of all included devices will not be
impaired by the combination intended.
Such a case might arise, if several devices were connected to the patient or the electrocardiograph and the
summarised lead current exceeded the admissible limits.
The devices are only allowed to be used by persons who due to their education, knowledge, and
practical experience can guarantee proper handling and who have been made familiar with the unit in
consideration of the Operating Manual.
Only those persons that due to their knowledge and practical experience are fit for briefing people on the
handling of these devices are allowed to instruct them.

INSERTION OF RECORDING PAPER
4 Putting into Operation
4.1 Insertion of Recording Paper
BIOSET 3700 requires thermoreactive recording paper as a block of continuous stationary of 180 sheets,
with a width of 110mm and a total length of 18m.
To ensure good recording quality and proper paper run, it is recommended to use only original recording
paper; it can be ordered from von Berg-Medizingeräte GmbH, order No. 2300-000-021.
Paper run
1 cover
2 thermal printing head
3 continuous stationary
4 cover opening button
5 imprint side
- press the cover opening button (4) to release the cover
- bring cover 1 into upright position and put it aside
- insert the paper block (3) into the chamber, place properly, and pull some paper out
Insert the block in such a manner, that the imprint side gets visible if the paper and is pulled to the left
(ref. to above illustration). The black paper marks are above (behind).
- reinsert cover 1
- bring the recording paper into a symmetric position toward the cover
- close the cover by slightly pressing its left verge
4.2 Application of electrodes
4.2.1 Resting ECG
Fix the supplied patient cable to the appropriate socket (item 8, ref. to p. 3-1).
The unit’s defibrillation protection is only effective with the patient cable supplied along
with the unit!
The electrodes should be applied to the appropriate skin areas which had been prepared before in the usual
manner.

EXERCISE ECG
4.2.2
Exercise ECG
The exercise ECG is acquired using either a suitable ECG suction-type electrode system or adhesive electrodes
and connected patient cables.
Defibrillation protection of unit will only be effective, if that patient cable specified in accessories
is used! For use of an ECG suction-type electrode system, consider possible pieces of advice of
the instructions.
Apply the electrodes to the skin areas specially prepared in advance.
Compared with the resting ECG, a modified positioning of the extremity electrodes will be required due to
muscle exercises.
