INFUSION INSTRUCTIONS - IF USING SQUIRT DEVICE
1. Fill the 20ml reservoir syringe with heparinized saline and debubble using
standard hospital protocol. This may include tapping the syringe with a
hemostat or similar device.
2. Attach reservoir syringe to Squirt. (Figure 2) Make sure that the syringe
connection is air-tight.
Note: The syringe rotator should be tightened by hand if using a syringe with
a rotating adapter.

3. Holding the Squirt in an upright position activate the trigger bar repeatedly until
all air bubbles are out of the check valve area of the Squirt. (Figure 2) This may
include tapping the Squirt fluid path with a hemostat or similar device.
Note: Clinician should attach a small piece of tubing if concerned about fluid
dripping out of the end of the Squirt during the priming process.
4. Turn Squirt such that the Sherlock connector is pointing up. Activate the trigger
bar until all air bubbles are out of fluid path. (Figure 3) This may include tapping
with a hemostat or similar device. This step may have to be repeated several
times to fully debubble the system.
5. Attach the Squirt to the hemostasis valve as shown in Figure 4. Prime the
hemostasis valve by placing a gloved thumb over the rotating adapter located
on the hemostasis valve while activating the Squirt. This will force saline out of
the back end cap of the hemostasis valve. Close the back end cap by twisting it
in a clockwise direction. (Figure 5) Continue to activate the Squirt to debubble
the distal segment of the hemostasis valve.
Warning: Do not connect the rotating adapter assembly to the Fountain
ValveTip Infusion Catheter at this time. If it is connected at this time, an air
embolism could occur potentially causing injury or death to the patient.

6. The Squirt should be activated so heparinized saline from the 20 ml reservoir
syringe comes through the back end cap of the hemostasis valve until all the air
has been displaced.
7. Continue to activate the Squirt. This will ensure that a liquid meniscus is at
the distal segment of the hemostasis valve. Attach the rotating adapter of the
hemostasis valve to the luer lock connector on the Fountain ValveTip Infusion
Catheter, making sure that a liquid-to-liquid connection is established.
(Figure 6)
8. Complete connection.
PRIMING THE SYSTEM WITH THERAPEUTIC SOLUTION
9. If the clinician wishes to conserve thrombolytic medication, the Squirt should be
primed as instructed previously.
10. Turn the Squirt until the syringe is pointing down. (Figure 7) Remove the
priming reservoir syringe that is loaded with sterile saline. Fill a syringe with
thrombolytic solution.
11. Using the thrombolytic solution syringe, place a small amount of thrombolytic
solution into the female luer connector of the Squirt. This will cause a small
meniscus of therapeutic solution to be placed on the female luer connector.
(Figure 8)
12. Attach the syringe loaded with therapeutic solution. (Figure 8)
Warning: Make sure that the connection is air-tight. If any bubbles
inadvertently enter the system they may be removed by activating the trigger
bar until all air bubbles are out of the fluid path. (The dead space volume is
approximately 0.5 ml.)
