Tielle Plus is an island dressing with a multi-layered structure consisting of a thin sheet of hydrophilic absorbent polyurethane foam applied to the centre of thin polyurethane foam membrane coated with an acrylic adhesive.
Between these two layers is a fibrous fleece containing a mixture of viscose and superabsorbent acrylate fibres.
When placed upon an exuding wound, the absorbent central island initially takes up liquid and expands to take up the shape of the wound bed. Excess fluid not retained by the primary wound contact layer is then drawn into the inner core of the dressing by the viscose fibres and taken up by the highly absorbent acrylate fibres to form a stable gel.
The wound contact surface of the dressing is covered with two pieces paper coated with a release agent that act as a carrier and facilitate application.
Tielle Plus is waterproof and the polyurethane foam backing forms an effective barrier to bacteria under normal conditions of use. The polyurethane foam backing is highly permeable to moisture vapour, a property that makes an important contribution to the total fluid-handling characteristics of the dressing.
Tielle Plus is indicated for use on most types of heavily exuding wounds such as leg ulcers, pressure sores and fungating wounds.
Frequency of Change
The frequency of dressing changes depends upon the condition of the wound and the amount of exudate produced. On some wounds Tielle Plus may be left undisturbed for up to 7 days but more frequent changes may be required on heavily exuding wounds.
