FAQ and useful tips
1.
Why can’t I visualise the veins
clearly?
Poor quality ultrasound images are caused by air
inside the blood. To improve the image, insert more blood into the cephalic and basilic
veins (please refer to the fluid system preparation on page 5). Approx. 10-20ml per vein
should be sufficient
2.
How often do I need to replace the ultrasound insert?
The ultrasound insert
comfortably facilitates 800+ needle penetrations using the recommended equipment
sizes (please refer to page 3). You can close one side of the fluid system when it is
destroyed by
switching the appropriate vein to ‘OFF’ (please refer to the
fluid system
preparation on page 5). The functioning side of the insert can still be used as normal
without leaks from the used side
3.
Why is the insert leaking when I refill blood into the veins?
Sometimes when refilling
blood into the system, you may see some small leaks on the insert from old punctures.
This is caused when the blood is being refilled too quickly through the syringe. To
minimize the leakage, enter the fluid
slowly
