TraumaSim Ulcer - Leg Mixed

• Medically accurate mixed aetiology leg ulcer presentation: Combined arterial and venous disease features — the most clinically complex ulcer type and the most challenging to assess and manage correctly.
• Completes the four-aetiology ulcer comparison set: Included in the Silicone Wound Kit — Clinical alongside Arterial, Venous, and Neuropathic variants for comprehensive ulcer differentiation education.
• Develops advanced ulcer assessment skills: Training on the mixed presentation challenges trainees to identify coexisting disease components and apply nuanced management decisions — not just pattern-matching to a single aetiology.
• Patient safety-relevant clinical competency: Mixed ulcer misclassification leading to inappropriate full compression in the presence of significant arterial disease is a genuine patient safety risk — realistic wound training develops the assessment accuracy that prevents it.
• Lower leg placement format: 12 cm x 12 cm — suited to the gaiter and lower leg region where mixed ulcers commonly present.
• Self-adhesive silicone construction: Applies directly to skin or manikin surfaces without additional adhesives.
• Tapered edges: Blend naturally into the surrounding surface for seamless presentation.
• Durable and reusable: Washable construction designed for repeated clinical skills training use.
• 11 skin tones available: Commonly requested tones held in stock; others manufactured to order.

What injury does this simulate?
A mixed aetiology leg ulcer — a chronic wound where both arterial insufficiency and chronic venous insufficiency are contributing simultaneously. The wound presents with features of both disease types, creating a more complex and clinically challenging presentation than either pure arterial or pure venous ulceration alone.

Why is mixed ulcer training more clinically demanding than pure aetiology training?
A pure venous ulcer and a pure arterial ulcer each have characteristic, relatively consistent clinical signatures that can be pattern-matched with training. A mixed ulcer presents with overlapping features from both aetiology types, requiring the clinician to identify both components, assess the degree of arterial compromise, and make nuanced management decisions based on the balance of disease. That requires a higher-order assessment skill than pattern recognition — one that comes from structured exposure to the mixed presentation alongside the pure variants.

What is the management implication of misclassifying a mixed ulcer?
The primary risk is applying full compression bandaging — the standard venous ulcer treatment — in a patient with significant arterial disease. Compression in the presence of compromised arterial perfusion can further reduce blood supply to the distal limb and accelerate tissue damage, potentially contributing to limb loss. The clinical safety standard is to assess Ankle-Brachial Index before applying compression, and to use modified or no compression when significant arterial disease is identified.

How does a mixed ulcer differ visually from pure arterial and venous ulcers?
Mixed ulcers present with characteristics of both. They may have the gaiter region location and irregular margins of a venous ulcer alongside wound base pallor or necrosis suggesting arterial compromise, or a combination of exudate levels and pain patterns that don't fit cleanly into either pure presentation. The mixed nature is what requires the clinician to look beyond a single dominant feature and assess the full clinical picture.

What training programs is this suited to?
Undergraduate and postgraduate nursing, enrolled nursing, wound care specialisation, vascular nursing, aged care, community health, and any program where complex chronic wound assessment and ulcer aetiology differentiation are curriculum elements.

Is this a wearable wound or a task trainer?
Neither. This is a self-adhesive silicone wound prosthetic — applied to skin or manikin surfaces. It has no internal function or strapping system.

Does it include bleeding capacity?
No. This is a static wound prosthetic designed for clinical assessment and wound recognition training.

How do I apply it?
Peel and apply directly to clean, dry skin or a manikin surface. The self-adhesive backing holds without additional adhesive. Tapered edges blend naturally into the surrounding surface.

Is it reusable?
Yes. All TraumaSim silicone wounds are washable and reusable. Clean gently after each use, allow to dry fully, and store flat to maintain the adhesive backing between sessions.

What skin tones are available?
11 tones are available: 00 Porcelain, 01 Light, 02 Medium, 03 Olive, 04 Medium Olive, 05 Rosy, 06 Warm Rosy, 07 Warm Tan, 08 Tan, 09 Dark Tan, and 10 Dark. Tone 01 Light is held in standard stock. Other tones are manufactured to order — contact TacMed Australia before placing your order to confirm availability and lead times.

What are the dimensions and weight?
The prosthetic measures 12 cm x 12 cm x 0.5 cm and weighs 0.1 kg.

Can I purchase this as part of a kit?
Yes. The Ulcer — Leg Mixed is included in the TraumaSim Silicone Wound Kit — Clinical. Contact TacMed Australia for individual purchase and other kit configuration details.
