Cardiac stimulator 4427 Easypace - Instructions for use
31/40
In the event of having to make a connection between an epicardium needle it will be
necessary to use the sterile bipolar cable F7818/30 for heart surgery that is fitted with
screw-on sockets.
WARNING !
Use of the F7818/30 bipolar cable for heart surgery
1. The cable is fitted with pints at one end that are easy to insert into the
outlet sockets of the 4427 device. The only precaution to be taken is that
of observing the correct insertion in to the matching colours. At the other
end there are two screw-on sockets, one red and the other black, for
housing the Patient connection terminals. In order to ensure that the
procedure is performed in maximum safety it is recommended making
the connection of the Patient terminals to the cable sockets before
connecting the corresponding pins to the stimulator. Always observe the
recommendation in point three above.
2. The cable sockets are designed to receive terminals with a diameter
varying from a minimum of 0.5 mm to a maximum of 2.0 mm. For an
ideal coupling it is necessary for the jaw openings of the socket to have
the same or a slightly larger diameter than that of the terminal to be
inserted. In order to adjust the diameter of the opening remember that it
can be increased (up to 2 mm) by rotating the socket protection in an
anticlockwise direction, and decreased (down to 0.5 mm) by rotating in
the opposite direction.
3. The epicardium needle usually has a diameter of approximately 1 mm.
Before inserting it into the socket it is recommended checking that its
opening has been suitably adjusted. Moreover, in order not to
compromise the efficacy of the locking system, it is recommended
inserting the needle by keeping it aligned with the axis of the socket and
subsequently tightening it securely in order to guarantee an efficacious
and mechanically sure electrical contract. Finally, it is recommended
protecting the residual metallic parts of the needle that protrude from the
insulated lining of the socket with the special hood, if foreseen, supplied
with the needle used, like for example with the FIAB MyopaceT, TZ and
P epicardium needles.
