Which syringes are compatible?
All syringes with unobstructed access to the needle hub, for example the Paroject and including the ”Gun Sprayers”, are compatible with NeedleOff.
Which needle and syringe types can’t be used?
Do not use Needleoff for any type of needle other than a straight, threaded (metric and imperial) dental needle. It’s not designed for other needle types (such as Luer-Lock), needles that are mounted to the syringe under an angle (such as Citoject) or devices that do not offer unobstructed access to the needle hub (such as Quicksleeper).
What do you mean by ‘NeedleOff operates hands-free’?
NeedleOff has been designed to be stable, with gripping feet, so you don’t have to hold the device with you free hand before inserting a needle. It’s strongly advised not to touch NeedleOff during the procedure. This further reduces the risk of a needlestick injury.
Do I need to press the needle down into NeedleOff?
No, just lowering the needle into the needle funnel and firmly holding the shaft (to prevent it from spinning) is enough for a successful procedure. In fact, you shouldn’t apply any downward pressure before or during the procedure at all to minimize the risk of forcing the needle back onto the thread.
What do I do with the syringe after the procedure?
To eliminate the risk of cross-contamination, it’s advised to clean the used syringe in accordance with the applicable hygiene protocol for contaminated medical instruments before the next use.
How long does the battery charge last?
We’ve designed NeedleOff to be by your side or passed around different treatment rooms for an entire working day. It’s advised to always start the day with a full charge.
What’s the capacity of the Sharptainer?
The Sharptainer is designed to hold up to 400 needles. When the number of procedures exceeds 250, the counter will blink, warning you to take extra caution. Consider replacing the Sharptainer. After 400 procedures, NeedleOff will no longer work with the Sharptainer.
How does NeedleOff register the needle count?
NeedleOff keeps track of the number of procedures performed with a specific Sharptainer. That means a interrupted or failed procedure will be counted as a procedure as well. The number of performed procedures is stored in the RFID chip of the Sharptainer.
Does NeedleOff include tracking options for medical waste?
Every Sharptainer comes with a built-in RFID tag, which includes a unique identifier code. This way, NeedleOff and the Sharptainer are fully compatible with the potential tracking of medical waste streams.
Can I empty a Sharptainer?
It’s not possible to empty a Sharptainer, which is intended to be sealed and safely disposed of when full. As the RFID chip registers the number of procedures performed, attempting to empty a Sharptainer is useless and unsafe.
Why would I need multiple Gripper Cassettes?
When you insert a used needle in the needle funnel, the Gripper Cassette is contaminated as well. In order to rule out any risk of cross-contamination, it’s advised to change out the Gripper Cassette before performing the next procedure, whether on the same patient or a different one.
How do I clean NeedleOff?
The NeedleOff housing can be conveniently cleaned with medical alcohol (70%). The Gripper Cassette can easily be removed from the device, and the needle funnel can be detached. The Cassette and funnel can both be cleaned with medical alcohol and a brush.
