How should the ulcer be prepared before applying the 3C Patch®?
On subsequent treatments, rinse with water and remove any loose residual 3C Patch®. If the 3C Patch® is integrated into the newly formed granulation tissue, do not remove it.
If the wound area has not changed over a few weeks, it may be necessary to perform another debridement before 3C Patch® is placed on the wound.
How many 3C Patch® treatments are needed?
Data from the Cohort study (Wagner Grade I and II DFU) gave a mean treatment time to healing of 11 weeks (11 weekly treatments) with a range of 3-20 weeks.2
Data from the RCT on hard-to-heal diabetic foot ulcers gave a mean treatment time of 10 weeks to healing.1
Is there a maximum number of applications?
Can the 3C Patch® come into contact with intact skin?
What if the 3C Patch® is very moist?
What if the patch appears to be very thick?
What if the patch is very thin?
Can I treat deep ulcers or ulcers with exposed tendons or bone contact?
You can also place a part of the patch in the bottom of the wound with the rest of the 3C Patch® up the sides.
What if the surrounding skin is macerated?
What is the correct way to place 3C Patch® into the wound?
Can the 3C Patch® be cut into shape so it fits to the ulcer?
How is the primary bandage applied?
Do not cover the entire primary dressing with tape, as wound fluid needs to be able to pass.
Do not remove the primary dressing between the weekly treatments at the hospital/clinic.
It is acceptable to lift the dressing and observe for infection in the wound during the week and of course replace the secondary dressing if needed.
Can silver dressings be used as a primary dressing?
Some nurses have reported that they prefer to use a silver primary dressing because they report that it prevents odour occasionally coming from the wound.
Which secondary dressing can be used with 3C Patch®?
How often should the secondary dressing be changed?
Can the patient take a bath between the treatment weeks?
Instruct the patient that if the dressing gets wet they should contact the nurse at the hospital and ask what to do. If the 3C Patch® has been placed in the wound for 3-4 days then remove the primary dressing and replace it with an appropriate absorbent dressing until the next weekly hospital visit takes place.
Can a compression bandage be combined with 3C Patch®?
How often can an ulcer be treated with 3C Patch®?
Can the 3C Patch® be stored or refrigerated?
What is the patient selection criteria for using 3C Patch®?
Can NWPT (negative wound pressure therapy) be combined with 3C Patch®?
No blood is drawn
WHAT HAPPENS IF THE DEVICE IS NOT COMPLETELY FILLED?
In the 3CP® Centrifuge User manual you can find photos demonstrating an acceptable fill level.
WHAT HAPPENS IF THE DEVICE BECOMES SEPARATED FROM THE NEEDLE HOLDER?
Be certain to lock the device in place when filling the device. It is better to allow more time to fill than to end the filling too soon. The device cannot be overfilled so wait until it stops filling before removing it from the needle holder.
How soon after drawing the blood sample should centrifugation begin?
The first high-speed centrifugation must take place before coagulation and the final centrifugation takes place after coagulation.
What is the difference between placing the device in the “one dot” or the “two dots” position in the centrifuge cups?
What happens if the process is stopped during the first centrifugation spin?
If the device is not positioned in the “one dot” position for the first spin, then the device cannot turn automatically and a patch will not be prepared.
Please also be aware that the STOP button will reset the memory so the process will start from the beginning with an 8-minute spin.
What if the centrifuge gives the message “Imbalance”?
The 3CP® Device may have been pressed too hard into the centrifuge cup and may have activated the imbalance sensor. The imbalance sensor is located in the left side and it can be quite sensitive.
If you are only centrifuging one device confirm that you have placed the 3CP® Device and the 3CP® counter balance directly opposite each other.
Check if the 3CP® Device is significantly under-filled and does not weigh the same (+/- 5 g) as the 3CP® counter balance. If this happens, you will need to fill an empty device with the appropriate amount of water to counterbalance the under filled device.
You must turn off the external power supply before the message in the display will disappear. For more information see the 3CP® Centrifuge User Manual.
What if the centrifuge stops immediately after starting?
Check that blood is filled to the same level in both devices.
What if the 3CP® Device cannot be placed into the “one dot” track?
What if the filter has not completely raised to the top of the device during the second centrifugation?
In rare cases, the 3CP® Centrifuge will fail to detect that the filter is not at the top and it will end the process – in this case the device should be repositioned in the “two dots” position and the centrifuge started by pressing “START”; this will start an 8-minute spin cycle which should be stopped manually after approximately 2 minutes to inspect if the filter comes up.
What if there is no 3C Patch® in the device after processing?
If the filter is at the top of the device but no 3C Patch® is present, the coagulation process did not complete before the second spin and no 3C Patch® will be available. In this situation, to obtain a patch, a new device is needed and the complete process, including a new blood sample, must be repeated.
In rare cases, user inspection is required when the centrifuge is not able to automatically detect coagulation and reads: “Coagulation Not Complete” or “Opaque Plasma.”
Pay attention to coagulation and wait longer with the 3CP® Device in the centrifuge with the lid closed to keep heat in and aid coagulation. Wait as needed and re-check that coagulation has occurred before undertaking the final 2-minute spin.
Does anticoagulant medication affect the coagulation?
Why does the 3C Patch® appear different from patient to patient?
What if there is a leakage in the centrifuge?
The cleaning should include unplugging the power cord, removing the rotor from the centrifuge and cleaning all components and the bowl with a mild cleaning agent followed by disinfection with alcohol based disinfectants and always in accordance with local regulations.
If there is a leakage in the centrifuge, fill out and submit a complaint form, and if you need to send the centrifuge for service you need to fill out a decontamination certificate and attach this to the centrifuge.
What if the lid of the centrifuge will not open?
Insert the 3 mm Allen key, provided in the tool bag, into the front of the centrifuge (see 3CP Centrifuge User Manual section 5.8) and turn counter-clock wise. This will open the centrifuge.
