Embodiment

[0158] Preparation of the gel according to the invention

[0159] Gel A

[0160] Place 23g 4-hydroxybutyl acrylate, 3g AMPS, 0.02g PEG400 diacrylate (from Sartomer), 50g glycerol, 30g PEG400 (from Sigma-Aldrich) and 0.15mg Omnirad 1000 (from IGM Resins) at high speed In a jar with a mixer, the UV initiator Omnirad is added to the mixture last. The raw materials were then mixed in a high-speed mixer at 2400 rpm for 2 minutes.

[0161] After mixing, place the jar in a dark box for at least 3 hours to eliminate bubbles in the gel solution.

[0162] The thin gel (up to 5 mm) was then cured under ultraviolet light for 20 seconds for absorption and opacity measurements. The thicker gel (25 mm) was cured under UV light for 1 minute for compression test and compression strength analysis.

[0163] The water content of Gel A was 9 wt%.

[0164] Gel B

[0165] Place 29.75g MPEG450A (from Sigma Aldrich), 0.25g PEG400diA (from Sartomer), 70g glycerin / urea (70 / 30 mix), and 0.1 Omnirad 1000 (from IG...

Abstract

The present invention generally relates to a medical dressing for prevention of pressure ulcers. The dressing comprises a gel pad having a low compressive strength; i.e. from 5 kPa to 60 kPa at a strain of 50%, as measured by the compression test described in the specification. The dressing reduces the shear and compression forces on the skin and in the underlying the soft tissue layers and prevents or mitigates the onset of pressure ulcers.

Description

Technical field [0001] The invention relates to a medical dressing including a gel pad. The dressing is suitable for preventing pressure sores. Background technique [0002] Pressure ulcers are local damage to the skin and / or subcutaneous tissues on bony protrusions due to continuous pressure usually combined with friction and shear forces. The main factors that cause pressure sores or crush injuries are pressure, shear, friction and unfavorable microclimate. Other factors inherent in the patient may also increase the likelihood of pressure ulcer development, such as hypoperfusion, decreased sensation, and nutritional deficiencies. Pressure ulcers often appear in people who stay in bed for various reasons, such as long-term hospitalization or other reasons of immobility. Pressure sores can also occur under medical equipment used for diagnostic or therapeutic purposes, such as nasogastric tubes, ventilation masks, and tracheostomy tubes. The rigid materials used in these devic...
