Compresses & First Aid

Compresses and first aid supplies are essential in every medical practice, sports club, and household. From reusable hot/cold compresses to instant cold packs and emergency blankets, HaseMed offers reliable products for rapid first response and therapeutic application.

Hot/Cold Compresses: Sizes and Uses

Reusable hot/cold compresses (also called gel packs) can be used both chilled and heated. HaseMed offers three proven sizes:

• 13 x 14 cm: Compact size for fingers, wrists, ankles, and smaller joints. Ideal for the sports bag and first aid kit.
• 16 x 26 cm: The standard size for knees, elbows, and shoulders. Versatile for sports injuries and post-operative cooling.
• 12 x 29 cm: Elongated format that adapts perfectly to the neck, back, and thigh. Especially suitable for treating muscle tension.

The gel filling in HaseMed compresses remains flexible even when frozen, allowing the compress to conform well to the affected body area.

Instant Cold Packs (Disposable)

Instant cold packs require no pre-cooling and are therefore the ideal companion for emergencies, sports events, and first aid kits. Snapping the internal capsule triggers an endothermic chemical reaction that cools the pack to approximately 0–4 °C within seconds. Cooling lasts about 15 to 20 minutes.

HaseMed instant cold packs are individually wrapped, have a long shelf life, and take up little space in a first aid kit.

Emergency Blankets (Gold/Silver)

Emergency blankets consist of a thin, metal-coated polyester film and serve to protect against hypothermia and overheating. The HaseMed emergency blanket (210 x 160 cm) has two sides:

• Gold side out: Reflects thermal radiation and protects against sun exposure and overheating.
• Silver side out: Reflects body heat back and protects against hypothermia in cold conditions. This is the more common application in emergency services.

What to Look For When Buying

• Gel compresses: Latex-free cover, flexible even when frozen, microwave-safe for heat applications.
• Instant cold packs: Individual packaging, CE marking, shelf life of at least 3 years.
• Emergency blankets: Adequate size (at least 200 x 150 cm), tear- and water-resistant, vacuum-packed for compact storage.

Correct application of compresses and first aid supplies can accelerate healing and prevent complications. Follow these guidelines for safe and effective use.

RICE Method for Acute Injuries

For sports injuries such as bruises, strains, and sprains, the RICE method is well established:

• R — Rest: Stop activity immediately.
• I — Ice: Apply cold — with a HaseMed hot/cold compress or instant cold pack. Never directly on the skin; always use a thin cloth as a barrier.
• C — Compression: Apply an elastic bandage to reduce swelling.
• E — Elevation: Elevate the injured body part above heart level.

Cold Application: Duration and Frequency

Cool the affected area for a maximum of 15 to 20 minutes per session. Allow at least 45 minutes between cooling phases for the skin to recover. Always wrap the compress in a thin cloth or use a compress sleeve to prevent frostbite.

Heat Application with Gel Compresses

HaseMed hot/cold compresses can also be heated — either in hot water (approx. 80 °C for 5 minutes) or in the microwave (600 watts, max. 30 seconds). Test the temperature on the back of your hand before applying. Heat therapy is particularly suitable for:

• Chronic muscle tension
• Menstrual pain
• Joint stiffness from arthritis
• Neck and shoulder complaints

Activating Instant Cold Packs Correctly

Snap the inner capsule by applying firm pressure in the centre. Shake the pack briefly to mix the contents. Cooling begins within seconds. Use the pack only once and dispose of it in household waste afterwards.

Maintaining Reusable Compresses

Clean the surface after each use with a damp cloth and mild detergent. Regularly inspect the cover for damage — replace the compress if torn or leaking. Store the compress flat in the freezer or at room temperature, depending on planned use.

First aid supplies and compresses are subject to European and national standards that ensure safety and efficacy. Knowledge of these standards is particularly relevant for practice operators, occupational physicians, and safety officers.

DIN 13157 and DIN 13169: First Aid Supplies

DIN 13157 (small first aid kit) and DIN 13169 (large first aid kit) define the minimum contents of first aid equipment in businesses. Instant cold packs are included in the DIN 13157 specification and must be present in every workplace first aid kit. HaseMed instant cold packs meet these requirements and are suitable as refills for existing first aid kits.

EU Medical Device Regulation (MDR 2017/745)

Reusable hot/cold compresses and instant cold packs are classified as Class I medical devices. They must bear a CE marking, have technical documentation, and meet the essential safety and performance requirements of the MDR. HaseMed compresses are certified accordingly and carry the CE marking.

DIN EN ISO 10993: Biological Evaluation of Medical Devices

DIN EN ISO 10993 governs the biological evaluation of materials that come into body contact. For gel compresses, this means the cover must be skin-compatible and must not release sensitising or toxic substances. HaseMed compresses are latex-free and tested for biocompatibility under this standard.

Emergency Blankets: DIN EN ISO 15223-1

Emergency blankets are classified as medical devices and must meet the labelling requirements of DIN EN ISO 15223-1. Labelling includes information about the manufacturer, date of manufacture, lot number, and intended use. HaseMed emergency blankets (210 x 160 cm) are CE-marked and available individually in compact vacuum packaging.

Workplace Ordinance (ArbStättV)

Under Section 4(5) of the German Workplace Ordinance, employers must maintain sufficient first aid materials. The type and scope depend on the size of the company and the specific hazards. Instant cold packs are recommended equipment, especially in businesses with increased injury risk (e.g. sports, manufacturing, construction).
