Description

Technology Field

[0001] Embodiments of the present invention relate to a pressure-reducing foam dressing bandage. Background Technology

[0002] Bandages are broadly classified into gauze-type bandages that come into direct contact with the affected area and compression bandages that immobilize the affected area.

[0003] Gauze-type bandages are made of highly elastic materials to protect the wound, stop bleeding, retain applied medication, absorb secretions, and provide local warmth while in direct contact with and wrapping the wound. Compression bandages, on the other hand, are made of highly elastic materials to aid wound healing through constant compression and to maximize the therapeutic effect.

[0004] Conventional medical compression bandages have the ability to apply a certain amount of pressure to the affected area by stretching with elasticity along the length when applied to the patient's wound; however, because they do not stretch in the width direction, they cannot naturally wrap around the curved parts of the wound, resulting in a gap between the wound and the medical compression bandage.

[0005] In addition, there was a problem in that medical compression bandages wrapped around curved parts of the wound would become separated from the wound, causing parts of them to wrinkle or protrude outward due to improper wrapping, thereby reducing the force of tight support to the wound. In particular, the wrinkled parts could potentially compress the skin, leading to infections such as chafing; consequently, existing medical compression bandages made of cotton material lost their original capabilities.

[0006] In addition, wearing bandages for a long time caused skin dryness and irritation, leading to skin damage. The problem to be solved

[0007] The embodiments of the present invention aim to provide a pressure-reducing foam dressing bandage that promotes lymph or blood flow by providing gradual pressure reduction from the distal to the proximal part through variations in the thickness of the material and foam constituting the bandage.

[0040] Referring to FIGS. 1 to 4, a pressure-reducing foam dressing bandage (1) according to one embodiment of the present invention comprises a bandage sheet (10) having different regions, a compression member (20), and an elastic part (30).

[0041] Here, the pressure-reducing foam dressing bandage (1) is a low-elasticity bandage that has low elasticity and high strength, so it can provide effective compression when there is movement.

[0042] In addition, the pressure-reducing foam dressing bandage (1) according to one embodiment of the present invention can provide pressure that gradually decreases as it moves from the distal part to the proximal part.

[0043] In detail, a pressure-reducing foam dressing bandage (1) according to one embodiment of the present invention can adjust the elasticity of the bandage sheet (10) and the pressure applied to the treatment area by adjusting the thickness of the foam layer (202) included in the compression member (20) and the number of elastic parts (30).

[0065] The degree of compression applied to the treatment area by the pressure-reducing foam dressing bandage (1) according to one embodiment of the present invention may vary depending on the thickness of the compression member (20). In one embodiment of the present invention, the first thickness (t1) of the first compression member (210) placed in the first area (A1) may be thicker than the second thickness (t2) of the second compression member (220) placed in the second area (A2), so that when the pressure-reducing foam dressing bandage (1) wraps the treatment area, the first area (A1) may provide stronger compression to the treatment area than the second area (A2).

[0066] Meanwhile, the first compression member (210) may include a first waterproof layer disposed on the bandage sheet (10) and a first foam layer disposed on the first waterproof layer. The second compression member (220) may include a second waterproof layer disposed on the bandage sheet (10) and a second foam layer disposed on the second waterproof layer.

[0067] The thickness of the first foam layer may be thicker than the thickness of the second foam layer, and due to this difference, the first area (A1) may provide stronger compression when the decompression foam dressing bandage (1) wraps the treatment area.

[0068] Meanwhile, the first foam layer and the second foam layer may contain moisturizing ingredients, and may contain moisturizing substances such as glycerin, hyaluronic acid, aloe vera, and propylene glycol.

[0069] The first elastic modulus and the second elastic modulus of a pressure-reducing foam dressing bandage (1) according to one embodiment of the present invention may be determined by the number of elastic members in each elastic part included in each region. Referring to FIG. 2, the first elastic part (310) and the second elastic part (320) may include elastic members (E) of the same material, but may have different numbers of elastic members. As illustrated, the first elastic part (310) may have two elastic members (E), and the second elastic part (320) may have one elastic member (E). Through this, the first elastic modulus of the first elastic part (310) may be greater than the second elastic modulus of the second elastic part (320).

[0070] Meanwhile, two or more first compression members (210) may be provided on the first area (A1) of the bandage sheet (10). For example, as illustrated, a plurality of first compression members (210) may be arranged in two rows, and at this time, the first elastic member (310) may be placed between the first compression members (210) arranged on the first area (A1) of the bandage sheet (10).

[0071] Two or more second compression members (220) may be provided on the second area (A1) of the bandage sheet (10). Likewise, a plurality of second compression members (220) may be arranged in two rows, and in this case, a second elastic member (320) may be placed between the second compression members (210) arranged on the second area (A1) of the bandage sheet (10).

[0075] Generally, when the thickness of the elastic member (E) increases, the stiffness of the elastic member increases, and thus a greater elastic force can be generated. Therefore, the elastic force of the first elastic part (310), which has a thicker elastic member, may be greater than the elastic force of the second elastic part (320).

[0076] When a pressure-reducing foam dressing bandage (1) according to another embodiment of the present invention wraps a treatment area, the first region (A1) in which the first elastic part (310) is placed can provide greater pressure due to elastic force, thereby providing stronger pressure to the treatment area in the second region (A2).
