PICO Negative Pressure Wound Therapy

About PICO

Single Use Negative Pressure Wound Therapy

PICO represents a unique way of treating patients who would benefit from the application of Negative Pressure Wound Therapy (NPWT). PICO has been shown to provide positive patient outcomes when applied to open wounds, closed surgical incisions and skin grafts1,2,3,4. 

The PICO system is canister-free which means the pump is small enough to fit in the palm of your hand. This makes the system very discrete and portable for the patient to wear2.

 The PICO pump generates an effective negative pressure of -80mmHg5 and provides therapy for up to 7 days.

The PICO pump is connected to a conformable, innovatively designed dressing which:

  1. Is easily applied and removed, minimising skin trauma2 and delivers the negative pressure across the wound bed or closed incision1
  2. Designed to reduce the risk of pressure points and supports patient comfort 6,7
  3. Manages the fluid away from the wound or closed incision through a unique combination of absorbency and evaporation1,5.

Provided together as a convenient all-in-one-system, canister-free PICO supports patients in maintaining their daily activities. Patients may be safely discharged with PICO in place2,3,8, the size and simplicity gives confidence that they can manage the system at home2,3,8.

Health care providers can be confident in using PICO because PICO has been shown to lead to improved patient outcomes and utilisation of resources across a range of wound types and care settings2,3,8,9.

PICO is presented to provide a week (7 days) of therapy. In each carton there is one pump plus two dressings complete with fixation strips. This enables a dressing change to be carried out within the therapy life of the pump if this is clinically necessary.

Being single use, PICO can be kept on the shelf to allow easy access to the therapy when it's needed.

The PICO pump may be recycled at the end of the weekly cycle.

Which Dressing Size to Choose


Choose a size of dressing that, when applied, allows coverage of the wound,graft or total length of the incision whilst keeping the port away from the area of injury.

How to Deal with an Air Leak/Low Pressure

 

  • Smooth the dressing and strips against the skin, it maybe that movement has caused the edge to lift a little.
  • Once this has been completed, press the orange button and the pump will try to re-establish the vacuum.
  • Whilst the pump is running the green light will flash. If the vacuum is successfully re-established the green light will continue to flash.
  • If air is still finding a way into the dressing, the yellow leak light will start to flash after approximately 30 seconds. Repeat the smoothing motion and press the orange button until the leak is resolved.

How to Change the Batteries

 

  • Press the orange button to pause the therapy.
  • Remove the battery cover from the top of the pump and remove the old batteries.
  • Replace with 2 new AA lithium batteries. An indication of which way up each battery should be placed is indicated inside the battery compartment.
  • Replace the cover.
  • Press the orange button to start the therapy.

Indications

PICO Single Use Negative Pressure Wound Therapy system is indicated for patients who would benefit from a suction device (Negative Pressure Wound Therapy) as it may promote wound healing via removal of low to moderate levels of exudate and infectious materials.

PICO Single Use Negative Pressure Wound Therapy System is suitable for use in both a hospital and community setting and approved for the following indications.

  • Acute wounds
  • Chronic wounds
  • Flaps and grafts
  • Partial-thickness burns
  • Subacute and dehisced wounds
  • Surgically closed incision sites
  • Traumatic wounds
  • Ulcers (such as diabetic or pressure)

 

Use with Fillers

PICO is compatible with the standard fillers of foam and gauze used with conventional NPWT if this is necessary1 .

A filler would be required if the PICO dressing on its own does not make intimate contact with the wound bed. This may be the case with wounds such as sinus’s, wounds with undermined edges and those with uneven surfaces.

Fluid Management

The PICO dressing has been uniquely designed to manage fluid in 2 ways2. The first is absorption into the superabsorbent layer and the second is by transpiration of the moisture through the breathable top film.

As fluid is removed from the wound bed, it first enters the airlock layer then is rapidly pulled away by the hydrophilic superabsorbent layer2. This part of the dressing forms a gel which acts to hold the fluid securely away from the wound.

Once the gel forms underneath the film at the top of the dressing, the film starts to evaporate off the moisture2 and an equilibrium is established to balance the amount of fluid in the dressing at any one point in time. This action prevents the dressing becoming heavy with fluid on the patient.

Evidence

To understand how PICO is being used to reduce wound healing complications following high risk procedures including:

  • Orthopaedic trauma
  • Orthopaedic reconstruction ( hip, knee and spine)
  • Cardiothoracics
  • Plastic reconstruction - reduction mammoplasty
  • Gynaecology – post caesarean section
  • General – patients with Crohns disease
