PICO is a canister-free, single-use, negative pressure wound therapy system consisting of a sterile pump and multi-layered adhesive dressings. Each dressing has 4 layers: a silicone adhesive wound contact layer, which is designed to minimise pain and damage during peel-back and to reduce lateral tension; an airlock layer for even distribution of pressure; an absorbent layer to remove exudate and bacteria from the wound; and a top film layer, which acts as a physical barrier and allows moisture to evaporate. The pump is operated by 2 AA batteries and delivers a continuous negative pressure of 80 mmHg to a sealed wound. Once activated, using a push button, the battery drives the pump for up to 7 days and LEDs provide alerts for low-battery status and pressure leaks.
