[0039] The disposable ear pressure relief pad of this utility model is described in detail below with reference to the accompanying drawings.

[0040] Reference Figures 1 to 4 As shown, the disposable ear pressure relief pad provided according to an embodiment of this utility model includes a flexible pad 10. The shape of the flexible pad 10 is adapted to the auricle, making it convenient to wear the flexible pad 10 on the auricle. For example, the flexible pad 10 has an arc-shaped strip structure. The side of the flexible pad 10 is provided with a groove H10 for accommodating the ear loop of an oxygen mask. When wearing an oxygen mask, when the ear loop of the oxygen mask is hanging on the ear, the ear loop is placed in the groove H10. In this way, the flexible pad 10 can be used to isolate the ear loop and avoid the ear loop from pressing on the auricle.

[0041] The flexible pad 10 includes an inner layer, a middle layer, and an outer layer. The inner layer is a skin-friendly layer 101, which can be made of medical-grade soft material and has good biocompatibility and breathability. Preferably, the inner layer 11 can be made of medical-grade silicone material, which not only has a soft touch but also excellent biocompatibility, effectively preventing skin allergies caused by long-term contact.

[0042] The middle layer, a cushioning support layer 102, can be made of a material with elastic deformation properties. For example, the middle layer can be made of memory foam, which has good pressure dispersion and resilience. When the ear loop applies pressure to the flexible pad 10, the middle layer can deform moderately, distributing the pressure evenly over a larger area, thereby significantly reducing localized pressure. In practical applications, the thickness of the middle layer can be set to 3-5 mm, which provides sufficient cushioning without causing discomfort.

[0043] The outer layer is an anti-slip layer 103, which can be made of a material with good anti-slip properties. Preferably, the outer layer can be made of medical-grade TPE material. This design increases the friction between the flexible pad 10 and the ear loop, preventing displacement during use.

[0044] Preferably, the width of the groove H10 is compatible with the width of common oxygen mask ear loops, typically set at 5-8mm. The depth of the groove H10 should be sufficient to accommodate the ear loops without affecting the overall structural stability, generally set at 3-5mm.

[0045] In practical applications, the disposable auricular decompression pad is used as follows: First, place the flexible pad 10 in the predetermined position on the patient's auricle, ensuring the inner layer fits tightly against the auricular skin; then, put on an oxygen mask and secure the ear loops of the oxygen mask in the groove H10. Because the shape of the flexible pad 10 conforms to the auricle, it provides a good fit while maintaining stability.

[0046] According to the embodiments of this utility model, the disposable ear pressure relief pad, through its flexible pad 10 design adapted to the shape of the ear, can effectively disperse the pressure of the oxygen mask's ear loop on the ear, reducing the pressure and potential damage caused by long-term wear. The grooved H10 structure on the side of the flexible pad 10 facilitates the fixation of the ear loop, enhancing the reliability of use. In addition, the three-layer structure design of the flexible pad 10, namely the skin-friendly layer 101, the cushioning support layer 102, and the anti-slip layer 103, provides a more comfortable wearing experience while ensuring the stability of the flexible pad 10 during use, thereby improving the patient's comfort and safety while ensuring the patient's oxygen needs.

[0047] Preferably, the inner wall of the groove H10 is provided with an anti-slip texture. This anti-slip texture can be an embossed pattern, such as a herringbone, grid, or wavy pattern. The anti-slip texture significantly increases the contact area and friction between the inner wall of the groove H10 and the ear loop, more effectively preventing the ear loop from slipping or shifting during use and improving the positioning effect of the groove H10 on the ear loop.

[0048] In one embodiment of the present invention, an indicator mark is also included, which is disposed on the surface of the flexible pad 10 to indicate the direction of use of the disposable ear pressure relief pad.

[0049] Indicator markings can use striking colors and clearly indicate the product's usage direction through arrows, text, or graphics. This design prioritizes convenience for healthcare workers during rapid application, providing intuitive guidance to users for correct wearing and preventing reduced effectiveness due to incorrect orientation. Indicator markings can be achieved through screen printing, embossing, or other processes, ensuring the markings are durable and do not compromise product comfort.

[0050] Preferably, the thickness of the flexible pad 10 gradually decreases from the center to the edge in the width direction. That is, the flexible pad 10 adopts a gradient thickness design that gradually decreases from the center to the edge in the width direction. This design gives the flexible pad 10 better fit and transition effect. Specifically, maintaining a thicker design at the center provides sufficient cushioning and support; while gradually thinning towards the edges allows for a natural transition with the skin, avoiding obvious sharp edges.

[0051] In one embodiment of the present invention, at least one side of the groove H10 in the width direction is provided with an inwardly protruding retaining edge, the retaining edge extending along the length direction of the groove H10.

[0052] The width of the baffle can be set between 1mm and 3mm. This range provides sufficient blocking effect without being too prominent and affecting the ear loop's entry into the groove H10. The cross-section of the baffle can be circular or rounded rectangular.

[0053] The extended design of the edge creates a blocking structure along the length of the groove H10, effectively preventing the ear strap from slipping out during wear. This design not only increases the reliability of the ear strap's fixation but also helps reduce the frequency of ear strap adjustments, providing a more stable wearing experience.

[0054] Advantageously, the flexible pad 10 is provided with a plurality of ventilation holes H11, which penetrate the inner layer, middle layer and outer layer. The ventilation holes H11 increase the ventilation and breathability of the flexible pad 10, which helps to reduce discomfort that patients may experience when wearing it for a long time and improves wearing comfort.

[0055] In one embodiment of the present invention, the flexible pad 10 is provided with positioning protrusions 1021 at both ends to prevent the flexible pad 10 from sliding on the auricle.

[0056] In this embodiment, the positioning protrusions 1021 are disposed at both ends of the flexible pad 10, which increases the stability of wearing the flexible pad 10. When wearing the flexible pad 10, the positioning protrusion 1021 at the front end of the flexible pad 10 can be hooked onto one end of the auricle, while the positioning protrusion 1021 at the rear end of the flexible pad 10 can be hooked onto the other end of the auricle. In this way, by utilizing the positioning function of the two positioning protrusions 1021, the stability of wearing the flexible pad 10 can be improved, preventing problems such as easy slippage and falling off the auricle.

[0057] In other words, with the help of the positioning protrusion 1021, the flexible pad 10 can better fit the curve of the ear, preventing it from slipping or falling off during activities or use, and providing a more reliable and comfortable wearing experience.

[0058] Preferably, the bottom surface of the positioning protrusion 1021 is provided with an adhesive layer 1021a, and the adhesive layer 1021a is covered with release paper. In use, the release paper can be removed, the flexible pad 10 can be worn on the patient's auricle, and finally, the positioning protrusions 1021 at both ends of the flexible pad 10 can be gently pressed. At this time, the adhesive layer 1021a at the bottom of the positioning protrusion 1021 can be adhered and fixed to the human body. In this way, a reliable guarantee is provided for the fixation of the flexible pad 10. During use, the flexible pad 10 is not easy to fall off the auricle, further improving its reliability and stability.
