Description

Technical Field

[0001] The utility model relates to a pressure ulcer prevention oxygen inhalation protection patch. Background Art

[0002] Ventilators are commonly used for respiratory failure caused by various reasons, anesthesia respiratory management during major surgeries, respiratory support treatment, and first aid resuscitation. The application of ventilators can not only prevent and treat respiratory failure and reduce complications, but also is a crucial medical device for saving and prolonging the lives of patients. Therefore, ventilators play a very important role in the field of modern medicine. During the use of ventilators, generally, an air inlet tube is connected to a ventilator mask, and then oxygen is delivered to the patient's mouth and nose through the ventilator mask.

[0003] Clinically, multiple gaps between the pressure ulcer prevention patch and the face are utilized to allow air flow, increase the air permeability of the face, and achieve the effect of preventing pressure ulcers. However, the overall structural design of the existing pressure ulcer prevention protection patch is relatively simple. For example, in the patent application with the publication number CN219595535U and the patent name of a pressure ulcer prevention protection patch, only a liquid seepage drainage channel and a water absorption layer are used to ensure that the contact area between the adhesive layer and the face remains dry for a long time to prevent the occurrence of pressure ulcers. However, due to the poor overall support stability of the pressure ulcer prevention protection patch, local pressure concentration is likely to occur during long-term use, resulting in pressure ulcers.

The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0020] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation on the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present utility model, "a plurality of" means two or more, unless otherwise specifically defined.

[0021] Embodiment 1: As Figure 1 shown, an anti-pressure ulcer oxygen inhalation protection patch includes an outer protective layer 1, a breathable layer 2, an oxygen inhalation layer 3, an absorption layer 4, a pressure dispersion layer 5, and an adhesion layer 6 which are arranged in sequence from outside to inside;

[0022] The outer protective layer 1 contacts with the breathing mask, and the adhesion layer 6 is attached to the skin surface; a plurality of grooves 601 are evenly distributed on the adhesion layer 6, and the grooves 601 protrude from the adhesion layer 6 towards the pressure dispersion layer 5; the grooves 601 are higher than the bottom end of the adhesion layer 6;

[0023] The pressure dispersion layer 5 is provided with a receiving groove 501 matching the groove 601, and the pressure dispersion layer 5 is made of an elastic material; the absorption layer 4 is made of a highly water-absorbent material, and the oxygen inhalation layer 3 is a foam or fiber material rich in oxygen;

[0024] A support layer 9 is further provided between the outer protective layer 1 and the breathable layer 2. The support layer 9 is made of polyurethane foam or ethylene vinyl acetate foam or glass fiber material, so that the support structure has a certain support property, and the support layer 9 is a grid structure or a honeycomb structure. The grid structure or the honeycomb structure further increases the structural strength of the support layer, which is beneficial to improving the support stability of the protection patch.

[0025] When the anti-pressure ulcer oxygen inhalation protection patch of the present utility model is in use, the outer protective layer 1 is in contact with the breathing mask, and the adhesive layer 6 is attached to the skin surface. Since the adhesive layer 6 is provided with a groove 601 protruding from the adhesive layer 6 towards the pressure dispersion layer 5, the adhesive layer 6 and the groove 601 are not in the same plane, and the groove 601 is set higher than the adhesive layer 6. Thus, when the adhesive layer 6 is attached to the patient's skin surface, the groove 601 does not contact the patient's skin, facilitating the ventilation of the skin corresponding to the groove; the setting of the receiving groove 501 on the pressure dispersion layer 5 enables the accommodation of the groove 601, and the pressure dispersion layer 5 is made of an elastic material, which is conducive to evenly dispersing the external pressure, reducing the local pressure concentration, and preventing damage to the skin and tissues; the absorption layer 4 absorbs and locks the exudate, keeps the wound or pressure area dry, prevents eczema and infection, and further reduces the risk of pressure ulcers; the oxygen inhalation layer 3 provides continuous oxygen supply to the skin, promotes the metabolic function of the skin and tissues, and helps prevent ischemia and tissue necrosis; the breathable layer 2 is conducive to enhancing the breathability of the protection patch, promoting air circulation, reducing moisture accumulation, keeping the skin fresh and dry, and preventing eczema and infection; the outer protective layer 1 effectively prevents external pollutants from entering, such as bacteria and water, while allowing air and water vapor to pass through, keeping the skin dry and reducing the risk of infection; the support layer 9 between the outer protective layer 1 and the breathable layer 2 enhances the overall structural strength of the protection patch, provides stable support, ensures that the protection patch maintains its shape and function during use, and will not deform or collapse due to pressure and friction; and the support layer can evenly disperse the external pressure, reduce the local pressure concentration, prevent damage to the skin and tissues, and avoid the occurrence of pressure ulcers.

[0026] As a preferred embodiment, the pressure dispersion layer 5 in the present application is a silica gel pad made of silica gel material; the silica gel material has elasticity and also has water absorption. While utilizing the elastic function of the silica gel to evenly disperse the external pressure, it also absorbs the exudate and keeps the wound or pressure area dry.

[0027] As a preferred embodiment, the absorption layer 4 in the present application is a superabsorbent fiber material or high molecular water-absorbing beads, which have good liquid absorption and seepage performance and lock the seepage liquid in the absorption layer 4 to avoid seepage; the breathable layer 2 is a microporous film or non-woven fabric material, which is conducive to improving the breathability of the protection patch; the outer protective layer 1 is a breathable polyurethane, which effectively prevents external pollutants from entering.

[0028] Example 2: As Figure 2 and Figure 3As shown, a buffer layer 7 and an antibacterial layer 8 are sequentially provided between the breathable layer 2 and the oxygen-absorbing layer 3 in this embodiment. The buffer layer 7 is made of silica gel. The buffer layer 7 provides additional buffering for the protective patch, absorbs impact force, reduces damage to the skin caused by friction and shear force, and enhances overall comfort. The antibacterial layer 8 is disposed on the buffer layer 7. The antibacterial layer 8 is a coating containing antibacterial drugs. The antibacterial layer 8 effectively inhibits the growth of bacteria and microorganisms, reduces the risk of infection, and keeps the wound or the compressed skin clean and healthy.

[0029] In the present application, the groove 601 of the self-adhesive layer 6 is arranged from large to small in the direction from the self-adhesive layer 6 to the pressure-dispersing layer 5. The groove position of the adhesive layer 6 does not contact the skin, maintaining the air permeability of the corresponding skin at the groove 601. While the groove structure arranged from large to small minimizes the contact area with the skin while maintaining air permeability, ensuring the air permeability of the skin. More specifically, the groove 601 is an arched structure. While maintaining the air permeability of the corresponding skin at the groove 601, the arched structure also increases the structural strength of the groove 601 and reduces the occurrence of the collapse of the groove 601.
