Arrow MAC Bedienungsanleitung Seite 4

When the tip is straightened, the spring-wire guide is ready
for insertion. Centimeter marks are referenced from "J" end.
One band indicates 10 cm, two bands 20 cm, and three bands
30 cm.
Introducing the Spring-Wire Guide:
• Place the tip of the Arrow Advancer™ – with "J" retracted – into
the hole in the rear of the Arrow
to Fig. 7).
• Advance spring-wire guide into the syringe approximately
10 cm until it passes through the syringe valves (refer to
Fig. 8).
• Raise your thumb and pull the Arrow Advancer
approximately 4 cm to 8 cm away from the syringe. Lower
thumb onto the Arrow Advancer
fi rm grip on the spring-wire guide, push the assembly into
the syringe barrel to further advance the spring-wire guide.
Continue until spring-wire guide reaches desired depth (refer
to Fig. 9).

Alternate Technique:
If a simple straightening tube is preferred, the straightening
tube portion of the Arrow Advancer
from the unit and used separately.
Separate the Arrow Advancer tip or straightening tube from
™
the blue Advancer unit. If the "J" – tip portion of the spring-
™
wire guide is used, prepare for insertion by sliding the plastic
tube over the "J" to straighten. The spring-wire guide should
then be advanced in the routine fashion to the desired depth.
12. Advance the guide wire until triple band mark reaches rear of
syringe plunger. Advancement of "J" tip may require a gentle
rotating motion. Warning: Do not cut spring-wire guide to
alter length. Do not withdraw spring-wire guide against
needle bevel to minimize the risk of possible severing or
damaging of spring-wire guide.
13. Hold spring-wire guide in place and remove introducer needle
and Arrow Raulerson Syringe (or catheter).

centimeter markings on spring-wire guide to adjust indwelling
length according to desired depth of indwelling sheath placement.
14. Enlarge cutaneous puncture site with cutting edge of scalpel
positioned away from the spring-wire guide.
not cut guide wire. Lock scalpel in the protected position.
15. Thread tapered tip of dilator/access device assembly over
spring-wire guide. Grasping near skin, advance assembly with
slight twisting motion to a depth suffi cient to enter vessel.
Dilator may be partially withdrawn to facilitate advancement
of access device through tortuous vessel.
withdraw dilator until the access device is well within the
vessel to minimize the risk of damaging the catheter tip.
16. Advance access device assembly off dilator into vessel, again
grasping near skin and using slight twisting motion.
17. To check for proper access device placement within the vessel,
attach syringe to distal side port for aspiration. Hold access
device assembly in place and withdraw spring-wire guide and
dilator suffi ciently to allow venous blood fl ow to be aspirated
into distal side port. Precaution: Maintain fi rm grip on
spring-wire guide at all times.
18. Holding access device assembly in place, remove guide
wire and dilator as a unit. Place sterile-gloved fi nger over
hemostasis valve. Warning: To minimize the risk of
possible vessel wall perforation do not leave tissue dilator
in place as an indwelling catheter. Warning: Although the
incidence of spring-wire guide failure is extremely low,
practitioner should be aware of the potential for breakage
if undue force is applied to the wire.
distal side port to appropriate line as necessary. Confi rm
and monitor proximal port by aspirating until free fl ow of
venous blood is observed. Connect all extension lines to
appropriate Luer-Lock line(s) as required. Unused port(s) may
can be disconnected
