High elastic bandages are the clinical workhorse for venous leg ulcers, lymphoedema, and post-surgical oedema — but they are also one of the most frequently mis-specified medical products. Compression-labelled bandages are Class IIa medical devices requiring Notified Body CE, not Class I. Long-stretch and short-stretch bandages have different pressure profiles and different patient indications. This guide covers both.
High elastic bandages — also called elastic compression bandages, extensible bandages, or long-stretch bandages — incorporate rubber or synthetic elastic yarns (elastane, polyurethane, or natural rubber) throughout the woven or knitted fabric structure. Unlike crepe bandages whose elasticity comes from high-twist yarn structure and progressively fades during wear, high elastic bandages maintain tension through the continuous recoil force of the integrated elastic yarns.
This sustained compression is the defining clinical property that makes high elastic bandages appropriate for therapeutic compression therapy — venous leg ulcer management, lymphoedema, DVT prophylaxis, and post-surgical oedema reduction. For related bandage type guidance, see our Medical Bandage Types Comparison Guide and our Crepe Bandage Specifications Guide.
The most important specification decision for elastic bandage procurement is not width or compression class — it is long-stretch vs short-stretch. The two bandage types have different pressure profiles that make them clinically appropriate for different patient scenarios.
| Property | Long-stretch (High elastic) ≥140% | Short-stretch <70% |
|---|---|---|
| Extensibility | Greater than 140% — highly extensible | 10–70% — low extensibility, stiffer |
| Resting pressure | High — exerts sustained pressure at rest | Low — minimal pressure when patient is at rest |
| Working pressure | Lower — less additional pressure during movement | High — significant additional pressure during muscle contraction |
| Pressure profile during movement | Continuous, sustained — pressure maintained through activity and rest | Intermittent — pressure increases during muscle contraction, falls at rest |
| Best patient profile | Ambulatory patients requiring sustained compression during activity | Oedema reduction phase; patients with poor mobility where low resting pressure is safer |
| Conformability | Excellent — moulds around heel, ankle, and irregular contours | Less conformable — may require padding on bony prominences |
| Risk in non-ambulatory patients | Higher — high resting pressure may impair circulation in prolonged recumbent position | Lower — low resting pressure reduces circulation risk when patient is in bed |
| Examples | High elastic bandage (this product), 4-layer compression system outer layers | Comprilan, short-stretch cotton bandages |
Long-stretch bandages exert their therapeutic effect primarily through resting pressure — the continuous recoil force of the elastic yarns. This sustained pressure on the superficial venous system, even during rest, is what drives venous blood return in ambulatory patients. The trade-off is that this same high resting pressure can become problematic if the patient is non-ambulatory for extended periods, as it may impair arterial and lymphatic flow. Short-stretch bandages exert most of their effect during the working pressure phase — muscle contraction against a relatively stiff bandage creates a pressure pulse that drives venous return. This is more appropriate for intensive oedema reduction phases in less mobile patients.
BS 7505:1995 (British Standard: Specification for the elastic properties of flat, non-adhesive, extensible fabric bandages) classifies long-stretch compression bandages by the ankle pressure generated under standardised test conditions: measured at 23 cm ankle circumference with 50% overlap. These values are reference points for comparing bandage performance — actual sub-bandage pressure in clinical use depends on application technique, individual limb shape, and the number of bandage layers applied.
Published clinical evidence (ScienceDirect, Sclerotherapy 5th Edition, 2011) indicates that approximately 30–40 mmHg at the ankle, reducing to 15–20 mmHg at the calf, is generally adequate for healing most types of venous leg ulcers. This corresponds broadly to BS 7505 Class 3b–3c. These are reference values for clinical guidance — actual sub-bandage pressure must be assessed in the context of individual patient vascular status, limb shape, and application technique. ABI (ankle-brachial index) assessment is required before applying high-compression bandaging to confirm adequate arterial circulation.
High elastic bandages without a compression class label are CE Class I medical devices — the lowest risk category, requiring only manufacturer self-declaration. However, the moment a bandage is labelled with a compression class or makes a specific mmHg compression claim, the regulatory classification changes.
Bandages claiming a specific compression class (e.g., BS 7505 Class 3b, or any mmHg pressure claim) are classified as CE Class IIa medical devices under EU MDR 2017/745. Class IIa requires: (1) Notified Body involvement in the conformity assessment; (2) Clinical evaluation data supporting the compression claims; (3) CE certificate showing the Notified Body name and number. For procurement teams specifying bandages for therapeutic compression therapy (venous leg ulcers, lymphoedema, DVT prophylaxis), a Class I CE certificate is not sufficient — it confirms the bandage is CE-marked but does not validate the compression claim. Always request the CE certificate and confirm the classification is Class IIa with Notified Body details before procuring compression-labelled bandages for therapeutic use.
The CE certificate should explicitly state the risk classification (Class I, Class IIa, Class IIb, or Class III) and, for Class IIa and above, the Notified Body name and 4-digit number. The certificate must reference "Regulation (EU) 2017/745" — not the expired "Council Directive 93/42/EEC." If a supplier provides a certificate that does not specify the classification, or shows Class I for a compression-labelled bandage, request clarification before proceeding with the order.
High elastic bandages are woven or knitted from cotton or polyester base yarns with rubber or synthetic elastic yarns integrated throughout the warp direction of the fabric. The elastic yarns are the source of both elongation and elastic recovery — their continuous recoil force is what maintains compression over time.
| Parameter | Specification | Notes |
|---|---|---|
| Base fabric material | Cotton, polyester, or cotton/polyester blend | Cotton provides softness and breathability; polyester provides durability and wash resistance |
| Elastic yarn type | Natural rubber (latex) or synthetic elastic (elastane/polyurethane) | Latex-containing variants are common — confirm if latex-free is required for your patient population |
| Extensibility (long-stretch) | 140–200% elongation | Source: ScienceDirect (Sclerotherapy 5th Ed, 2011). Defined as long-stretch per BS 7505:1995 |
| Elastic recovery | High — elastic yarns continuously recoil to maintain compression | Fundamental difference from crepe bandage which loses tension progressively during wear |
| Weight per m² | Typically 75–90 g/m² (varies by compression class) | Source: Henso Medical product specifications. Higher weight generally correlates with higher compression class |
| Fabric clips | 1 or 2 metal clips standard; elastic band clips available | Specify clip type and quantity at order — metal clips not appropriate for all patient groups |
| Latex content | May contain natural rubber latex (elastic yarn) — confirm explicitly | Latex-free synthetic elastic variants available — specify if latex-free is required |
| Clinical scenario | Recommended | Notes |
|---|---|---|
| Venous leg ulcer compression | High elastic, BS 7505 Class 3b–3c | ABI assessment required before application. Graduated compression (higher at ankle, lower at calf) — apply from toes upward with reducing tension |
| Lymphoedema management | High elastic or short-stretch depending on phase | Intensive oedema reduction phase: short-stretch preferred. Maintenance phase: high elastic acceptable |
| DVT prophylaxis (post-surgical) | Class 3a–3b | Anti-embolism stockings are the preferred modality; compression bandage as alternative where stockings are not appropriate |
| Sports injury support (sprain/strain) | High elastic, unclassified (no compression label) | For light support and oedema control in acute sports injury — Class I CE acceptable. Not therapeutic compression therapy. |
| Splint fixation / post-fracture | High elastic over padding | Apply over undercast padding or orthopaedic wadding — never directly on skin without padding |
| Post-surgical limb compression | Class 3a–3b | Graduated compression applied by trained clinician — confirm arterial status before applying |
