Single Use Negative Pressure Wound Therapy System
US 1850465234057
PICO™ is supplied sterile, single use. Do not use if package is open or damaged.
wound healing via removal of low to moderate levels of exudate and infectious materials.
1. Description
Examples of appropriate wound types include: • Chronic • Acute • Traumatic • Subacute and dehisced wounds • Partial-thickness burns • Ulcers (such as diabetic or pressure) • Flaps and grafts • Closed surgical incisions
The PICO Single Use Negative Pressure Wound Therapy System consists of a pump and two sterile dressing kits. The PICO pump maintains negative pressure wound therapy (NPWT) at 80 mmHg (nominal) +/- 20 mmHg to the wound surface. Exudate is managed by the dressing through a combination of absorption and evaporation of moisture through the outer film. PICO is intended for use in wound sizes (surface area x depth) up to 400 cm3 which are considered to be low to moderately exuding. The kit is intended to be used for a maximum of 7 days on low exuding wounds and 6 days on moderately exuding wounds. Therapy duration of the kit may be less than indicated if clinical practice or other factors such as wound type, wound size, rate or volume of exudate, orientation of the dressing or environmental conditions, result in more frequent dressing changes.
2. Indications for use PICO is indicated for patients who would benefit from a suction device (negative pressure wound therapy) as it may promote
PICO Single Use Negative Pressure Wound Therapy System is suitable for use both in a hospital and homecare setting.
3. Contraindications The use of PICO is contraindicated in the presence of: • Patients with malignancy in the wound bed or margins of the wound (except in palliative care to enhance quality of life). • Previously confirmed and untreated osteomyelitis. • Non-enteric and unexplored fistulas. • Necrotic tissue with eschar present. • Exposed arteries, veins, nerves or organs. • Anastomotic sites. • Emergency airway aspiration. • Pleural, mediastinal or chest tube drainage. • Surgical suction.
4. Warnings 1. Certain patients are at high risk of bleeding complications which, if uncontrolled, could potentially be fatal. Patients must be closely monitored for bleeding. If sudden or increased bleeding is observed, immediately discontinue therapy, leave dressing in place, take appropriate measures to stop bleeding and seek immediate medical assistance. 2. The use of anticoagulants does not deem a patient inappropriate for treatment with PICO however hemostasis must be achieved before applying the dressing. Patients suffering from difficult hemostasis or who are receiving anticoagulant therapy have an increased risk of bleeding. During therapy, avoid using hemostatic products that may increase the risk of bleeding, if disrupted. Frequent assessment must be maintained and considered throughout the therapy. 3. At all times care should be taken to ensure that the pump and tubing does not: • Lie in a position where it could cause pressure damage to the patient. • Trail across the floor where it could present a trip hazard or become contaminated. • Present a risk of strangulation or a tourniquet to patients.
• Rest on or pass over a source of heat. • Become twisted or trapped under clothing or bandages so that the negative pressure is blocked. 4. Sharp edges or bone fragments in a wound must be covered or removed prior to using PICO due to risk of puncturing organs or blood vessels while under negative pressure. 5. In the event that defibrillation is required, disconnect the pump from the dressing prior to defibrillation. Remove the dressing if it is positioned in a location that will interfere with defibrillation. 6. MR Unsafe. PICO is not MRI compatible. Do not take PICO into the MRI suite. 7. PICO has not been studied on pediatric patients. Patient size and weight should be considered when prescribing this therapy. 8. PICO is unsuitable for use in areas where there is danger of explosion (e.g. hyperbaric oxygen unit).
5. Precautions 1. Precautions should be taken in the following types of patients who are at high risk of bleeding complications:
• Receiving anticoagulant therapy or platelet aggregation inhibitors or actively bleeding. • Having weakened or friable blood vessels or organs in or around the wound as a result of, but not limited to; anastomoses, infection, trauma or radiation. • Suffering from difficult wound hemostasis. • Untreated for malnutrition. • Noncompliant or combative. • Suffering from wounds in close proximity to blood vessels or delicate fascia. 2. PICO dressings should only be applied by a healthcare professional. Dressings are not to be removed or changed by the patient. 3. Where PICO is used on infected wounds, more frequent dressing changes may be required. Regular monitoring of the wound should be maintained to check for signs of infection. 4. If deemed clinically appropriate, care should be taken that the application of a circumferential dressing does not compromise circulation. 5. PICO does not contain audible alarms. The pump should be carried so that it is accessible and the patient/ healthcare professional can check the status routinely. 6. Although PICO can be used under clothing/ bedding, it is important that occlusive materials e.g. film dressings,
are not applied over the pad area of the dressing as this will impair device performance. 7. Where PICO is used on patients with fragile skin, a skin protectant such as SKIN-PREP™ should be used on areas of skin where fixation strips are to be applied. Inappropriate use or repeated application of fixation strips may otherwise result in skin stripping. 8. If reddening or sensitisation occurs discontinue use and contact the treating healthcare professional. 9. Do not use PICO with oil-based products such as petrolatum as it may compromise establishing an effective seal. 10. The use of negative pressure presents a risk of tissue ingrowth into foam when this is used as a wound filler. When using foam filler with PICO, tissue ingrowth may be reduced by using a wound contact layer or by increasing the frequency of dressing changes. 11. PICO may be used in conjunction with surgical drains provided the dressing is not placed over tubing where it exits the skin. Any surgical drain should be routed under the skin away from the edge of the dressing and function independently of the PICO Single Use Negative Pressure Wound Therapy System. 12. When showering the PICO pump should be disconnected from the dressing. Ensure the end of the tubing attached to the dressing is facing
down so that water does not enter the top of the tube. 13. Do not take the pump apart. 14. The dressing should not be used with any other suction pump. 15. Do not alter or cut tubing configuration or pull on the tubing. 16. Do not cut the dressing as this may lead to loss of NPWT application. 17. Always ensure that the dressing is positioned centrally over the wound. The port should be positioned uppermost on intact skin and not extend over the wound so that the risk of fluid collecting around the port and potentially blocking the negative pressure is minimised. 18. CT scans and x-ray have the potential to interfere with some electronic medical devices. Where possible, move the device out of the x-ray or scanner range. If the device has been taken into the CT scan or x-ray range, check that it is functioning correctly following the procedure. 19. This device is single use only. Use of any part of this system on more than one patient may result in cross contamination that may lead to infection. 20. High temperatures and humidity may reduce wear times of dressings. 21. During transport, there is a potential for radio frequency interference that could affect PICO performance. If the device malfunctions, replace batteries. If not
corrected, contact your caregiver to replace the device. PICO is not intended for use aboard aircraft, the batteries should be removed during air travel. 22. The potential for electromagnetic interference in all environments cannot be eliminated. Use caution if PICO is near electronic equipment such as RFID (Radio Frequency Identification) readers, anti-theft equipment or metal detectors.
6. Adverse Reactions Excessive bleeding is a serious risk associated with the application of suction to wounds which may result in death or serious injury. Careful patient selection, in view of the above stated contraindications, warnings and precautions is essential. Carefully monitor the wound and dressing for any evidence of a change in the blood loss status of the patient. Notify the healthcare professional of any sudden or abrupt changes in the volume or the color of exudate.
7. Instructions for use 7.1. Guidance on wound suitability for management with PICO PICO should be used on wounds which fit comfortably within the area of the pad, observing precautions on port positioning (on intact skin and not extending over the wound).
As a guide: 1
Depth – Wounds greater than 0.5cm ( /4 in.) in depth are likely to require a foam or gauze NPWT filler to ensure adequate treatment of all the wound surfaces. Wounds treated with the larger dressing sizes of the PICO system should generally be no more than 2cm (4/5 in.) in depth. Exudate – PICO is intended for use on wounds where the level of exudate is low (nominally 0.6g of liquid exudate/cm2 of wound area/24 hours) to moderate (nominally 1.1g of liquid exudate/cm2 of wound area/24 hours). 1g of exudate is approximately equal to 1ml of exudate. When used on a moderately exuding wound, the size of the wound should generally be no more than 25% of the dressing pad area.
7.2. Application 1. Remove any excess hair to ensure close approximation of the dressing to the wound. If necessary, irrigate the wound with sterile saline and pat the wound dry. 2. Using a clean technique, peel off the central release handle and place the dressing centrally over the wound to reduce the chance of wound fluid coming into contact with the port. The port should be uppermost from the wound (depending on the patient’s primary position), placed on intact skin
and not extending over the wound to prevent fluid pooling around the port and blocking the negative pressure. Remove the other two handles and smooth the dressing around the wound to prevent creasing. Reposition if required to ensure border is not creased.
3. Once the dressing is in place, remove the pump and the batteries from the tray. Insert the batteries. Replace the cover. Following this all three lights should flash once. (Refer to Table 1). 4. Join the pump to the dressing by twisting together the tubing connectors. Press the orange button to start the application of negative pressure. The green light will start to flash (indicates system working OK, see Table 1). Depending on the size of the wound, the pump should take up to 30 seconds to establish negative pressure wound therapy. If after 30 seconds the system has not established negative pressure wound therapy, the amber air leak light will illuminate. To troubleshoot refer to section (ii) of Table 1.
7.3. Dressing change
5. If using SKIN PREP prior to application of the fixation strips (see Precautions), wipe the area surrounding the dressing and allow skin to dry. 6. Apply the fixation strips to each of the four sides of the dressing. Remove top carrier on the strip after each one has been applied. These strips maintain the seal over the wear time of the dressing. In awkward areas, it may be useful to apply the strips to help achieve a seal prior to switching on the pump. Place each strip so that it overlaps the dressing border by approximately 1cm (2/5 in.). Ensure tubing is not twisted or trapped between clothing.
1. Dressings should be changed in line with standard wound management guidelines, typically every 3-4 days. More frequent dressing changes may be required depending on the level of exudate, condition of the dressing, wound type/size, orientation of the dressing, environmental considerations or other patient considerations; e.g. when PICO is used on infected wounds. At the healthcare professional’s discretion a PICO dressing may be left in place for up to 7 days. 2. Inspect the dressing regularly. If the dressing appears ready for changing (see diagrams A-C), press the orange button and disconnect the dressing from the pump. The fixation strips should be stretched away from the skin and the dressing lifted at one corner and peeled back until it has been fully removed. Apply another dressing as per section 7.2, connect to the pump and press the orange button to reinitiate the therapy.
Please note that if at any time the fixation strips are removed, the dressing should also be replaced.
A B C (A) Dressing properly positioned and is acceptable to be left in place (B) Dressing requires change – Port may block with fluid (C) Dressing requires change – Absorbent area is full
3. Based on dressing change frequency, a new PICO Single Use Negative Pressure Wound Therapy System kit will be required dependent on whichever of the following occurs first either when both dressings have been used or after 7 days when the pump automatically stops functioning (all the lights will turn off at this point). 4. The dressing should be disposed of as clinical waste. The batteries should be removed from the pump; and both batteries and pump disposed of according to local regulations. 5. For additional information on disposal requirements see: www.possiblewithpico.com
7.4. Use with fillers and wound contact layers PICO is compatible with standard gauze and foam fillers used in traditional NPWT where this is clinically appropriate – for example on a defect wound. When a filler is used, the filler and the PICO dressing should be changed 2 to 3 times a week, according to local clinical protocol and manufacturer’s instructions. Gauze should loosely fill to the surface of the wound. Avoid over packing. PICO may be used over the top of a nonadherent layer if required, for example over a skin graft. On infected wounds or wounds at risk of infection, ACTICOAT™ Flex silver-coated
antimicrobial dressings may be used under PICO.
8. General use 8.1. Showering and bathing Light showering is permissible; however, the pump should be disconnected (see Precautions) and placed in a safe location where it will not get wet. The dressing should not be exposed to a direct spray or submerged in water. Ensure the end of the tubing attached to the dressing is facing down so that water does not enter the top of the tube.
8.2. Cleaning Adherence to clinical directives concerning hygiene is of prime importance. The pump may be wiped clean with a damp cloth using soapy water or a weak disinfectant solution.
9. Faults and technical assistance If your device develops a fault or there are signs of damage, refer to Table 1.
Table 1 – Pump status indication, alarms and faults PICO has visual alarms to let the user know when there is an issue. PICO does not contain audible alarms.
