Description

Technical Field

[0001] The utility model belongs to the technical field of clinical nursing, and in particular relates to a heat-insulating earmuff for preventing pressure sores. Background Art

[0002] Long-term bedridden patients are in a passive lying position for a long time, and their skin and muscles are continuously compressed, causing local hypoxia and pressure sores. Pressure sores often occur on bony protuberances that are not wrapped in muscles or have a thin muscle layer, lack the protection of fat tissue and are often compressed. Therefore, patients who are lying on their side are prone to pressure sores on the auricle. In order to avoid or reduce the occurrence of pressure sores as much as possible, some anti-pressure sore earmuffs are currently provided in the prior art, such as the Chinese utility model patent with publication number CN219148198U. Although its structure can provide good support and protection for the auricle, in the side-lying state, due to the overall support of the earmuffs, it will also cause greater pressure on the ear root position, which is easy to cause pressure sores at the ear root for a long time. In addition, the ear temperature of critically ill and weak patients is lower than that of other parts of the body. In winter, when the room temperature is low, the ears are prone to frostbite and cause discomfort to the patients. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a heat-insulating earmuff for preventing pressure sores.

[0004] The content of the utility model includes a cover tube for being mounted on the ear, the cover tube is made of a flexible material, one end of the cover tube is an open end, and the other end is provided with an elastic cushion to form a closed end, a strap is provided on the outside of the open end of the cover tube, and the strap can be wrapped around the outside of the open end of the cover tube to tighten the end of the cover tube.

[0005] Furthermore, after the binding belt tightens the open end of the cover cylinder, the position of the binding belt on the end of the cover cylinder is fixed by binding.

[0006] Furthermore, after the binding strap is tightened around the open end of the cover tube, the position of the binding strap on the open end of the cover tube is fixed by Velcro.

[0007] Furthermore, the Velcro includes a barbed surface and a round surface, one end of the strap is fixed to the outside of the open end of the cover tube, the barbed surface is arranged on the inner side of the other end of the strap, the round surface is arranged on the outside of the strap, and the size of the round surface in the length direction of the strap is larger than the size of the barbed surface in the length direction of the strap.

[0008] Furthermore, one surface of the elastic cushion located inside the cover tube is a concave-convex surface.

[0009] Furthermore, one surface of the elastic cushion located inside the cover tube is wavy to form the concave-convex surface.

[0010] Furthermore, a surface of the elastic cushion located inside the cover tube is provided with a plurality of elastic protrusions at intervals to form the concave-convex surface.

[0011] Furthermore, the cover tube is made of cotton cloth.

[0012] Furthermore, the elastic cushion is made of rubber, sponge, air cushion or silicone.

[0013] Furthermore, when the material of the elastic cushion is an air cushion or silicone, the air cushion or silicone is a transparent material.

[0014] The utility model has the beneficial effect of using an elastic cushion to cushion and decompress the auricle of a side-lying patient, thereby reducing the pressure on the auricle of the side-lying patient, thereby preventing the occurrence of auricular pressure sores. Since the cover tube is made of a flexible material, it has the ability to deform. When the patient lies on his side, the cover tube is naturally deformed by force and will not generate a large pressure on the ear root. Therefore, on the basis of preventing the occurrence of auricular pressure sores, the ear root is prevented from being subjected to large pressure and causing pressure sores.

[0015] The use of a flexible cover tube with a strap, and the cover tube with an untightened open end can make it easier to clean and disinfect the inside of the earmuff, and can also make it easier to put the earmuff on the patient's ear, and then tighten it with the strap to fix it on the ear. On the one hand, this setting method can adapt to patients with different ear sizes by adjusting the tightening degree of the strap, that is, adjusting the size of the tightened open end of the cover tube, so as to effectively prevent the earmuff from falling off the ear as a whole when it is suitable for different patients, play an effective protective role, and ensure that the elastic cushion is always facing the surface of the auricle. On the other hand, after tightening, a relatively closed space can be formed inside the earmuff, which completely wraps the ear, reduces the speed of exchange of ear heat and the cold air from the outside, and has a better thermal insulation effect, avoiding frostbite and discomfort in the patient's ears in an environment with relatively low room temperature.

[0021] like Figure 1-Figure 4 As shown, the utility model provides a heat-insulating earmuff for preventing pressure sores, the earmuff comprises a cover tube 1, the cover tube 1 is used to be mounted on the ear, the cover tube 1 is made of a flexible material, that is, the cover tube 1 has the ability to deform. One end of the cover tube 1 is an open end, through which the cover tube 1 can be mounted on the ear, and the other end of the cover tube 1 is provided with an elastic cushion 2 to form a closed end, and the elastic cushion 2 is made of a material with a certain degree of elasticity and softness. When the cover tube 1 is mounted on the ear, its open end is located at the base of the ear, and the elastic cushion 2 is arranged facing the surface of the auricle. A strap 3 is provided on the outside of the open end of the cover tube 1, and the strap 3 can be wrapped around the outside of the open end of the cover tube 1 to tighten the end of the cover tube 1, so that the size of the open end of the cover tube 1 is reduced, thereby fixing the earmuff on the ear as a whole.

[0022] The utility model uses an elastic cushion 2 to buffer and decompress the auricle of a side-lying patient, thereby reducing the pressure on the auricle of the side-lying patient, thereby preventing the occurrence of auricular pressure sores. Since the cover tube 1 is made of a flexible material, it has the ability to deform. When the patient lies on his side, the cover tube 1 is naturally deformed by force and will not produce a large pressure on the ear root. Therefore, on the basis of preventing the occurrence of auricular pressure sores, the ear root is prevented from being subjected to large pressure and causing pressure sores.

[0023] In addition, the flexible cover tube 1 is combined with the strap 3, and the cover tube 1 with the open end not tightened can make it easier to clean and disinfect the inside of the earmuff, and can also more easily put the earmuff on the patient's ear, and then tighten it with the strap 3 to fix it on the ear. On the one hand, this arrangement can adjust the tightening degree of the strap 3, that is, adjust the size of the tightened open end of the cover tube 1, so as to adapt to patients with different ear sizes, so that when it is suitable for different patients, it can effectively prevent the earmuff from falling off the ear as a whole, play an effective protective role, and ensure that the elastic cushion 2 is always facing the surface of the auricle. On the other hand, after tightening, a relatively closed space can be formed inside the earmuff, which completely wraps the ear, reduces the speed of exchange of ear heat and external cold air, and has a better thermal insulation effect, avoiding frostbite and discomfort in the patient's ears in an environment with relatively low room temperature.

[0024] In one embodiment of the present invention, after the tie band 3 tightens the open end of the cover tube 1, the position of the tie band 3 on the end of the cover tube 1 is fixed by binding, that is, by tying the tie band 3. In this setting mode, it is only necessary to set the length of the tie band 3 to be longer to meet the use requirements, and the setting of other fixing parts can be omitted.

[0025] In a preferred embodiment of the utility model, after the strap 3 tightens the open end of the cover tube 1, the position of the strap 3 on the end of the cover tube 1 is fixed by Velcro, that is, it is fixed by Velcro. In this setting mode, the length of the strap 3 can be set shorter, the fixing and removal of the strap 3 are more convenient and simple, the convenience of use is higher, and it can avoid the local hard protrusion at the knot after the strap 3 is tied, which causes discomfort to the ear root.

[0026] The Velcro includes a burr surface and a round burr surface 5 that can be adhered to each other. In the above-mentioned embodiment using Velcro, one end of the strap 3 is fixed to the outside of the open end of the cover tube 1, and the other end is a free end. The burr surface is arranged on the inner side of the other end of the strap 3, that is, arranged on the inner side of the free end of the strap 3, and the round burr surface 5 is arranged on the outside of the strap 3. Figure 3 and Figure 4 As shown, after the bandage 3 is wrapped around the outside of the open end of the cover tube 1, the bristle surface is pasted with the round bristle surface 5, and the open end of the cover tube 1 is tightened, and the size of the open end becomes smaller. It is further preferred that the size of the round bristle surface 5 in the length direction of the bandage 3 is larger than the size of the bristle surface in the length direction of the bandage 3. By pasting the bristle surface and the round bristle surface 5 at different positions, the tightening degree of the open end of the cover tube 1 can be adjusted, thereby adjusting the size of the tightened open end. In this setting, the round bristle surface 5 is set on the outside of the bandage 3. Since the round bristle surface 5 is a small and soft fiber, it is relatively soft. Even if its size in the length direction of the bandage 3 is larger than the bristle surface, after pasting with the bristle surface, part of it is still located on the outer surface of the bandage 3, and it is not easy to rub the patient's skin behind the ear and cause discomfort.

[0027] In one embodiment of the utility model, one side of the elastic cushion 2 located inside the cover tube 1 is a conventional plane, and forms surface contact with the auricle when in contact with the auricle.

[0028] In other embodiments of the utility model, one side of the elastic cushion 2 located inside the cover tube 1 is a concave-convex surface, that is, an uneven surface. Since the elastic cushion 2 has a certain elasticity and softness, it will collapse and deform under pressure, so that the raised part of the uneven area will produce a certain relative sliding when in contact with the ear, thereby massaging and stimulating the auricle acupuncture points.

[0029] The specific setting mode of the concavoconvex surface can be that the side of the elastic cushion 2 located inside the cover tube 1 is wavy, and the wavy shape forms the concavoconvex surface, and the vertex of the wavy shape is the convex part in the concavoconvex surface. In this setting mode, the concavoconvex surface can be integrally formed with the elastic cushion 2, which is convenient for processing.

[0030] In another configuration, a plurality of elastic protrusions 4 are arranged at intervals on one side of the elastic cushion 2 located inside the cover tube 1. The plurality of elastic protrusions 4 form the concave-convex surface, and the apex of the protrusions is the convex part of the concave-convex surface. In this configuration, the elastic protrusions 4 can be attached to the elastic cushion 2, and the shape and distribution thereof are more flexible.

[0031] The material of the cover tube 1 is cotton cloth, which meets its flexible deformation ability, is easy to obtain and has low cost, and has a corresponding heat preservation effect while also having a certain air permeability. Compared with materials such as silicone, it can improve the air permeability inside the earmuff. Preferably, the cover tube 1 is specifically made of double-layer cotton cloth or thickened cotton cloth, such as cotton cloth with a relatively high gram weight, so that it has a certain thickness to ensure that it can have a relatively ideal heat preservation effect. The material of the strap 3 can also be preferably cotton cloth or other flexible materials.

[0032] The elastic cushion 2 is made of rubber, sponge, air cushion or silicone, ensuring that it has a certain degree of elasticity and softness to reduce the pressure on the auricle of the side-lying patient. It is further preferred that the elastic cushion 2 is made of air cushion or silicone, and the air cushion or silicone is a transparent material that is light-permeable, so that the nursing staff can observe the auricle through the elastic cushion 2 without removing the earmuffs.

In line with the concept of the present application, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of different aspects of one or more embodiments of the present application as described above, which are not provided in detail for the sake of simplicity.

[0034] One or more embodiments of the present application are intended to cover all such substitutions, modifications and variations that fall within the broad scope of the present application. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of the present application should be included in the protection scope of the present application.
