Abstract
Description
Technical Field
[0001] This utility model relates to a nursing pad, and more particularly to an adhesive pressure-relieving nursing pad. Background Technology
[0002] When skin tissue is subjected to prolonged pressure or friction, such as after a long surgery when the patient cannot turn over during the procedure, pressure ulcers often develop on the face or in other areas.
[0003] Currently, silicone fat pads are commonly used to prevent pressure ulcers. However, operating rooms maintain low temperatures to ensure a sterile environment and stable operation of surgical equipment. In low temperatures, silicone fat pads tend to harden, making them ineffective at distributing pressure and preventing pressure ulcers and nerve damage. Therefore, adhesive foam dressings are often used as cushioning and pressure-relieving tools in operating rooms and clinical care. However, these adhesive foam dressings often suffer from poor breathability or excessive stickiness, leading to redness, swelling, allergies, or damage to the affected skin after prolonged use. Therefore, developing more breathable and adhesive pressure-relieving tools suitable for a wider range of temperatures is an ongoing effort. Utility Model Content
[0004] The purpose of this invention is to provide an adhesive pressure-relieving nursing pad.
[0005] This utility model of an adhesive pressure-relieving nursing pad includes a pressure-relieving layer and an adhesive unit.
[0006] The pressure-reducing layer is made of a polyurethane-based material. The adhesive unit is attached to a portion of the surface of the pressure-reducing layer and includes an adhesive layer and a bonding layer between the adhesive layer and the pressure-reducing layer.
[0007] The area ratio of the bonding layer to the adhesive layer is between 0 and 1, and the area ratio of the adhesive layer to the area of the pressure-reducing layer is between 0.05 and 0.9.
[0008] Preferably, in the adhesive pressure-relieving nursing pad of the present invention, the thickness of the bonding layer is in the range of 0.01~0.1 mm.
[0009] Preferably, in the adhesive pressure-relieving nursing pad of this invention, the thickness of the pressure-relieving layer is between 0.5 and 5 cm.
[0010] Preferably, in the adhesive pressure-relieving nursing pad of this invention, the moisture permeability of the adhesive unit is between 800 and 2000 g / m². 2 / 24hrs.
[0011] Preferably, in the adhesive pressure-relieving care pad of this invention, the area of the adhesive layer to the area of the pressure-relieving layer is 0.6.
[0012] Preferably, the adhesive pressure-relieving nursing pad of this utility model is used for hemorrhoid care, and the ratio of the area of the adhesive layer to the area of the pressure-relieving layer is 0.15.
[0013] Preferably, in the adhesive pressure-relieving nursing pad of this utility model, the area ratio of the bonding layer to the adhesive layer is 0, and the adhesive layer is directly coated on the surface of the pressure-relieving layer.
[0014] Preferably, in the adhesive pressure-relieving nursing pad of the present invention, the area ratio of the bonding layer to the adhesive layer is greater than 0, the bonding layer is adhered to the surface of the pressure-relieving layer, and the adhesive layer is adhered to the surface of the bonding layer.
[0015] The beneficial effects of this invention are as follows: by selecting the material of the pressure-reducing layer and controlling the ratio of the area of the adhesive layer to the area of the pressure-reducing layer, the adhesive layer does not completely cover the pressure-reducing layer, allowing the pressure-reducing layer to maintain its elasticity, and the larger area of the pressure-reducing layer can be used to increase the pressure reduction, isolation, and absorption effects. Attached Figure Description
[0016] Figure 1 This is a cross-sectional side view of an embodiment of the adhesive pressure-relieving nursing pad of this utility model; and
[0017] Figure 2 This is a cross-sectional schematic diagram of another embodiment. Detailed Implementation
[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0019] Before this utility model is described in detail, it should be noted that similar elements are represented by the same reference numerals in the following description.
[0020] See Figure 1 A first embodiment of the adhesive pressure-relieving nursing pad of this utility model includes a pressure-relieving layer 2 and an adhesive unit 3.
[0021] The pressure-reducing layer 2 is made of polyurethane material, and its thickness is between 0.5 and 5 cm. In this first embodiment, the pressure-reducing layer 2 is made of hydrophilic or hydrophobic polyurethane foam, and the polyurethane foam is manufactured according to the method described in the applicant's invention patent application No. TWI733503 in Taiwan, China. Therefore, the applicant will not elaborate further here, but will state it in advance. Preferably, the pressure-reducing layer 2 is hydrophilic polyurethane foam, which gives the pressure-reducing layer 2 the functions of high elasticity, skin-friendliness, and moisture absorption.
[0022] The adhesive unit 3 is attached to a portion of the surface of the pressure-reducing layer 2 and includes an adhesive layer 32 and a bonding layer 31 between the adhesive layer 32 and the pressure-reducing layer 2.
[0023] It should be noted that the purpose of the bonding layer 31 is to support the adhesive, which can be selected from pressure-sensitive hot melt adhesive, acrylic pressure-sensitive adhesive, or silicone, to bond the adhesive layer 32 to the pressure-reducing layer 2. Therefore, the presence or absence of the bonding layer 31, as well as the area of the bonding layer 31, can be appropriately adjusted according to the manufacturing process of the adhesive layer 32. For example, when the bonding layer 31 is bonded to the pressure-reducing layer 2 in a roll form, the adhesive layer 32 needs to be bonded to the pressure-reducing layer 2 using the bonding layer 31 that carries the adhesive. In this case, the area ratio of the bonding layer 31 to the adhesive layer 32 is >0, the area of the bonding layer 31 can be less than or equal to the area of the adhesive layer 32, and the thickness of the bonding layer 31 is between 0.01 and 0.1 mm. When the adhesive layer 32 is formed by coating, the adhesive layer 32 can be directly coated and formed on the pressure-reducing layer 2 without forming the bonding layer 31. In this case, the area ratio of the bonding layer 31 to the adhesive layer 32 is 0.
[0024] The adhesive layer 32 is bonded to a portion of the surface of the pressure-reducing layer 2 and is selected from acrylic pressure-sensitive adhesives or polyurethane adhesives. In this embodiment, the adhesive layer 32 is adhered to a portion of the surface of the pressure-reducing layer 2 and is bonded to the pressure-reducing layer 2 through the bonding layer 31. The bonding layer 31 is composed of a polyurethane film, and the area of the bonding layer 31 is equal to the area of the adhesive layer 32.
[0025] Since the adhesive pressure-relieving pad is applied directly to the user's skin using the adhesive layer 32, this invention utilizes the fact that the adhesive layer 32 does not completely cover the surface of the pressure-relieving layer 2, and controls the peel force of the adhesive layer 32 to between 0.2 and 0.6 kgf / inch, so that the adhesive layer 32 can effectively adhere to the area around the user's affected skin, and can prevent damage to the affected skin when the user removes the adhesive pressure-relieving pad.
[0026] See Figure 1Taking the use of the adhesive pressure-relieving nursing pad of this utility model for facial care as an example, the adhesive layer 32 can be an acrylic pressure-sensitive adhesive. By controlling the ratio of the area of the adhesive layer 32 to the area of the pressure-relieving layer 2 to 0.6, and making the adhesive layer 32 located at the edge of the pressure-relieving layer 2 in a long strip shape, it can not only fix the facial dressing used for facial care but also achieve the purpose of pressure relief and protection. However, in actual implementation, the adhesive layer 32 is not limited to being long strip-shaped or located at the edge of the facial dressing; it only needs to achieve the purpose of adhering to and fixing the facial dressing. Preferably, the adhesive layer 32 can be distributed and attached to areas with less stress, so that the pressure-relieving layer 2 without the adhesive layer 32 corresponds to areas with greater stress, such as the forehead near the eyebrows, the brow bone, or the cheekbone.
[0027] Furthermore, when the ratio of the area of the adhesive layer 32 to the area of the pressure-reducing layer 2 is large (for example, the ratio is greater than 0.3), the moisture permeability of the adhesive unit 3 needs to be increased to avoid skin irritation or allergies on the user's face. Preferably, the moisture permeability of the adhesive unit 3 is between 800 and 2000 g / m². 2 / 24hrs, to increase the moisture permeability and breathability of the adhesive pressure-relieving nursing pad of this utility model.
[0028] See Figure 2 Taking the use of this adhesive pressure-relieving nursing pad for hemorrhoid care as an example, the adhesive layer 32 can be polyurethane adhesive. Furthermore, since the affected area is often surrounded by body hair, and a hemorrhoid dressing is often used during hemorrhoid care, the adhesive area can be minimized. That is, the area of the adhesive layer 32 should be much smaller than the area of the pressure-relieving layer 2 (sufficient to fix the hemorrhoid dressing). A larger pressure-relieving layer 2 increases the pressure-relieving and isolation effect, and the smaller area of the adhesive layer 32 also reduces irritation to the user's affected area. Preferably, when the adhesive pressure-relieving nursing pad is used for hemorrhoid care, the ratio of the area of the adhesive layer 32 to the area of the pressure-relieving layer 2 is between 0.1 and 0.5. More preferably, the ratio of the area of the adhesive layer 32 to the area of the pressure-relieving layer 2 is 0.15.
[0029] In summary, the adhesive pressure-relieving nursing pad of this utility model, by controlling the ratio of the area of the adhesive layer 32 to the area of the pressure-relieving layer 2, can be applied to different affected areas of different users. It can achieve a larger area of the adhesive layer 32 and the bonding layer 31 to meet the needs of the user's face, or achieve a larger area of the pressure-relieving layer 2 to increase the pressure-relieving and isolation effect without causing irritation to the affected area. Therefore, it can indeed achieve the purpose of this utility model.

Any simple equivalent changes and modifications made in accordance with the claims and description of this utility model shall still fall within the scope of this utility model.
