Description

Technical Field

[0001] This utility model relates to medical devices, specifically to an ear cover. Background Technology

[0002] In clinical practice, critically ill patients, those who are bedridden for extended periods, and those with impaired consciousness often require oxygen therapy. When oxygen equipment is secured to the patient's head, the straps or tubing used to hold the equipment in place can compress or damage the auricle and surrounding skin. In particular, the protruding part of the auricle is at risk of pressure injury when the patient is in a lateral decubitus position. Because the auricle is composed only of cartilage and lacks subcutaneous fat connective tissue, it is not resistant to pressure, and once injured, it heals slowly. Furthermore, pressure injuries to the auricle not only increase patient suffering but also increase medical costs and the workload of healthcare workers. Existing auricle covers, however, are prone to rubbing against the skin behind the auricle with the patient's movements, rendering them ineffective. Additionally, patients experience increased oil and sweat production, reducing patient comfort and making the covers more likely to fall off. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an ear cover that is not easy to fall off even when the patient moves, reducing the pulling and friction of the nasal oxygen tube on the auricle and the surrounding skin, avoiding pressure damage to the auricle and the surrounding skin, and improving the patient's wearing comfort.

[0004] To achieve the above effects, this utility model provides an auricle cover, including a cover body, the cover body having a liner extending outward, the liner being adapted to fit against the skin of the back of the head on the auricle, the cover body having an open end, the cover body forming a cavity, the cavity communicating with the open end for fitting the cover body onto the helix, the cover body comprising, from the inside out, a skin-friendly layer, an absorbent layer and a support layer.

[0005] Preferably, the end of the sleeve body away from the bushing is rolled inward to form a rolled edge, and a gap is formed between the rolled edge and the inner side of the sleeve body.

[0006] Preferably, the end of the rolled edge is curved to fit the rolled edge into the groove on the inner side of the helix.

[0007] Preferably, an elastic layer is provided between the absorbent layer and the support layer.

[0008] Preferably, the bushing and the bushing body are integrally formed.

[0009] Preferably, a groove structure is formed at the connection between the outer side of the sleeve body and the bushing, and the groove structure is suitable for fitting the ear root.

[0027] See Figures 1 to 3The basic embodiment of this utility model provides an auricle cover, including a cover body 1, a sleeve 2 extending outward from the cover body 1, the sleeve 2 being adapted to fit the skin of the back of the auricle, the cover body 1 having an open end 3, and a chamber 9 formed in the cover body 1, the chamber 9 communicating with the open end 3 for fitting the cover body 1 onto the auricle. The cover body 1 includes, from the inside out, a skin-friendly layer 1-1, an absorbent layer 1-2, and a support layer 1-3. The skin-friendly layer 1-1 can be made of multiple layers of medical gauze sewn together, or it can be made of materials such as silicone or natural fiber fabric to ensure a comfortable wearing experience for the patient. The absorbent layer 1-2 can be made of viscose fiber, or other materials as needed. The skin-friendly layer 1-1 has several holes to facilitate the operation of the absorbent layer 1-2. The skin-friendly layer 1-1 makes the patient more comfortable to wear, and the absorbent layer 1-2 can absorb the sweat of the patient during wear. To reduce secretions and improve patient comfort, the support layer 1-3 can be made of thin metal sheets, such as medical-grade stainless steel, titanium alloy sheets, etc., as well as other composite materials. The support layer 1-3 provides certain support for the skin-friendly layer 1-1 and the absorbent layer 1-2, making the structure of the auricle cover more stable and thus maintaining a certain shape. In addition, the support layer 1-3 has elastic deformation properties, making it easy for patients to wear and fit the auricle after wearing. The support layer 1-3 provides necessary structural support, allowing the auricle cover to maintain a certain shape and fit the auricle, making it less likely to fall off. The liner 2 fits against the skin of the back of the auricle, further improving the stability of the auricle cover when worn, while protecting the auricle and the skin around the auricle, reducing the pulling and friction of the strap on the auricle and the skin around the auricle, and avoiding pressure damage to the auricle and the skin around the auricle.

[0028] In some embodiments, see Figure 4 and Figure 5 The end of the sleeve body 1 away from the sleeve 2 is rolled inward to form a rolled edge 8. The rolled edge 8 and the inner side of the sleeve body 1 form a gap. The rolled edge 8 is less likely to cause a stinging sensation to the skin, making it more comfortable to wear. The gap between the rolled edge 8 and the inner side of the sleeve body 1 makes it easier for the auricle sleeve and the helix to cooperate with each other. The rolled edge 8 fits the groove of the helix, making the fit between the helix and the auricle sleeve tighter and less likely to fall off.

[0029] In some embodiments, see Figure 4 and Figure 5 The end of the rolled edge 8 is curved to fit the groove on the inner side of the helix. The depth of the groove on the helix varies, so the height of the rolled edge 8 corresponds to the depth of the groove. The height of the rolled edge 8 is set according to the depth of the groove to adapt to the wearer's needs. In order to facilitate the use of the patient, the size of the auricle cover can be designed in a variety of different specifications.

[0030] In some embodiments, see Figure 3 An elastic layer 1-4 is provided between the absorbent layer 1-2 and the support layer 1-3. The elastic layer 1-4 can be made of materials such as rubber or memory foam. The elastic layer 1-4 can provide a cushioning effect and is less likely to squeeze the patient's auricle. As the contour of the auricle changes, the elastic layer 1-4 will shrink or bulge adaptively, making it easier for the cover body 1 to fit the auricle and improving the patient's wearing experience.

[0031] In some embodiments, the liner 2 and the body 1 are integrally molded parts, and the liner 2 and the body 1 are made of the same material and process. The liner 2 also includes a skin-friendly layer, which further improves the wearing effect for patients. There are no seams or connection points between the liner 2 and the body 1, which improves the strength and durability of the overall structure of the auricle cover.

[0032] In some embodiments, see Figure 3 The outer side of the sleeve body 1 and the bushing 2 are connected to form a groove structure 4. The groove structure 4 is suitable for fitting the ear root. The groove structure 4 allows the straps or accessories of the oxygen inhalation device to pass through. The groove structure 4 is a reserved passage for the straps or oxygen delivery tubes, which can effectively avoid direct pressure on the skin. When the patient moves, the groove structure 4 can restrain the straps. For patients who need to use the oxygen inhalation device for a long time, the groove structure 4 can better fit the contour of the ear root area, which is conducive to improving the comfort of wearing it for a long time.

[0033] In some embodiments, see Figure 1 and Figure 3 The main body 1 has multiple ventilation holes 5, which are evenly distributed on the main body 1 to further enhance the breathability of the ear cover and promote air circulation. The ventilation holes 5 help reduce the risk of skin irritation or infection caused by sweat and moisture retention, reduce heat and moisture accumulation in the wearing area, reduce the chance of bacterial and fungal growth, maintain a healthy skin condition, and improve the overall comfort of the wearer.

[0034] In some embodiments, see Figure 1 The cover body 1 has at least two gaps 6, which are located on the side away from the bushing 2. By setting the gaps 6, the cover body 1 is divided into multiple parts, each of which can undergo independent elastic deformation. Since each part can undergo independent elastic deformation, the overall structure is more flexible and adaptable, making it easier for patients to wear or remove the ear cover.

[0035] In some embodiments, see Figure 2 The surface of the skin-friendly layer 1-1 is provided with several anti-slip protrusions 7. The anti-slip protrusions 7 can effectively increase the friction between the ear cover and the skin contact surface, so that the ear cover fits more firmly on the ear. At night or when the patient is unconscious, it reduces unintentional movements that may cause the ear cover to shift or fall off.

[0036] In some embodiments, see Figure 2 The cross-section of the cover body 1 is U-shaped, which better wraps around part of the auricle, providing a more natural fit. It can be slightly adjusted according to the contour of the ear to ensure that the ear cover is firmly attached to the auricle. At the same time, it can reduce the pressure on the auricle and the surrounding area, help relieve discomfort or pressure that may occur when wearing it for a long time, avoid pressure damage, and improve the comfort of the patient.
