HaseMed Reusable Hot/Cold Compress Blue 21 x 38 cm

Large-Format Hot and Cold Therapy for Back, Thigh and Abdomen

The HaseMed Reusable Hot/Cold Compress in blue, 21 x 38 cm, is the large-format gel pack designed to cover extended muscle groups in a single application. Where a small pack only reaches a wrist or ankle, this generous rectangular format wraps around the lumbar spine, the quadriceps, the hamstring, the abdomen or the shoulder blade area, delivering a uniform layer of heat or cold across the whole target zone. It is the professional choice for physiotherapists, sports clubs, occupational health rooms and households that need one reliable compress to handle big-area complaints.

Filled with a temperature-retaining gel and sealed in a durable, skin-friendly blue outer layer, the pack stays flexible in both the freezer and the microwave, moulding itself to the contour of the body instead of sitting as a rigid block. That flexibility matters most on curved regions like the lower back or the side of the thigh, where a stiff ice pack would leave cold spots and hot spots. The HaseMed compress distributes temperature evenly, so the full 21 x 38 cm surface stays therapeutically active from the first minute to the last.

Why the 21 x 38 cm Size Is Different

• Built for large muscle groups: Covers the full lumbar region, a complete quadriceps, the entire abdomen or a shoulder-to-scapula span in one placement.
• Uniform temperature across the whole surface: The gel flows to fill the pouch evenly, eliminating the cold spots that ruin smaller packs.
• Flexible when frozen, soft when warmed: Conforms to curved body regions instead of forming a rigid slab, so therapy contact stays complete.
• Reusable and economical: A single compress replaces dozens of single-use ice bags or heat patches.
• Easy-clean blue surface: Smooth, non-porous outer layer wipes down in seconds between patients or family members.
• Fits standard large fixation sleeves: Compatible with most 21 x 38 cm hot/cold pack covers and back-wrap bandages.

Cold Therapy: Large-Area Relief After Impact and Overuse

Used cold, the 21 x 38 cm compress is ideal for the kind of injuries where a pocket-sized pack simply is not big enough. A hard fall on the coccyx, a contusion across the thigh, a lumbar strain after lifting, a bruised rib cage, post-exercise inflammation in the lower back, a swollen calf after a long hike, acute menstrual cramps, a tension headache radiating down the neck and shoulders, a sprain of the knee or elbow where the swelling extends well beyond the joint capsule. In each of those situations, cooling a wider area reduces blood flow and swelling across the full injured zone, not just a spot in the middle. Standard protocol is 15 to 20 minutes on, at least 20 minutes off, always with a thin cloth between the frozen compress and the skin.

Heat Therapy: Deep Muscle Relaxation for Chronic Tension

Warmed, the same compress becomes a large-area muscle relaxant. Lower back stiffness from hours at a desk, tight hamstrings before a run, cramping abdominal muscles, chronic shoulder tension, menstrual discomfort, warm-up before a massage or a stretching session, and the kind of deep-seated trapezius and rhomboid knots that build up during long workdays all respond to broad, gentle warmth. Because the 21 x 38 cm surface covers the full muscle belly rather than a single point, heat penetrates evenly and encourages circulation across the whole group. Patients feel the difference compared with a small heat pad that only warms one spot and leaves the surrounding muscle cold and contracted.

Who Uses This Size

• Physiotherapy practices: Pre-massage warming, post-mobilisation cooling, and kryotherapeutic applications across the lumbar and thoracic regions.
• Sports clubs and athletic trainers: Pitch-side cooling for thigh contusions, hamstring strains and large joint swelling; locker-room warming before training.
• Occupational health rooms: On-site relief for back pain, neck-shoulder tension and repetitive-strain flare-ups in office and industrial settings.
• Rehabilitation centres: Supportive large-area therapy during the recovery phase after orthopaedic procedures, following professional guidance.
• Home use: Menstrual cramps, chronic lower back pain, post-gardening soreness, bruises from falls, and family-wide first-aid support.

How to Prepare and Apply

• For cold therapy: Place the compress flat in the freezer at a minimum of -18 degrees Celsius for at least 2 hours before use. Store it in the freezer between applications so it is always ready.
• For heat therapy (microwave): Heat at 700 watts for approximately 10 seconds, check the temperature, and extend in short additional intervals if needed. Never exceed safe handling temperature.
• For heat therapy (hot water): Immerse the sealed compress in hot water at a maximum of 80 degrees Celsius for up to 4 minutes, then dry the outer surface before placement.
• Application time: 15 to 20 minutes per session is the standard therapeutic window. Repeat after an appropriate break if required.
• Always use a barrier: Place a thin cloth or textile layer between the compress and the skin to prevent thermal injury.
• After use: Wipe the outer surface with a mild cleaner, allow it to dry, and return it to storage.

Important Safety Notes

For external use only. Inspect the compress before every application and do not use if the outer layer shows any damage, leaks or discoloration. Never apply the pack directly onto broken, irritated or highly sensitive skin; always interpose a textile layer. Adapt temperature and application duration to individual tolerance and to any professional medical advice received. Do not use on patients with circulatory disorders, sensory impairments or cold intolerance without medical guidance. Keep out of the reach of children during preparation. The 21 x 38 cm format is compatible with most hot/cold pack fixation sleeves and support bandages of matching size.
