Description

Technical Field

[0001] The utility model relates to the field of inflatable air cushions, in particular to an inflatable air cushion for medical treatment of bedsores. Background Art

[0002] Pressure ulcers are a common condition in bedridden patients, particularly those who are extremely weak or have lost sensory and motor function. When patients sleep in the same position for extended periods, the constant pressure on the skin and muscles between bony prominences and the bed surface can lead to localized blood flow impairment and oxygen deprivation, ultimately causing vascular occlusion and tissue necrosis, resulting in symptoms such as erythema, blisters, and ulcers. Pressure ulcers typically develop at pressure points on the body, such as the hips, ischial spine, and sacrum. Their primary clinical manifestations include erythema, blisters, and ulcers at these pressure points. In severe cases, these ulcers can penetrate deep into the muscle layer and even into the bones and joints. Pressure ulcers not only increase nutritional depletion and cause systemic infection, but also increase the financial and care burden on patients and their families. For paraplegics, in particular, pressure ulcers can recur and worsen without effective preventive measures. Therefore, preventing the development of pressure ulcers is crucial.

[0003] In existing technologies, anti-bedsore air mattresses are commonly used to prevent and assist in the treatment of bedsores in bedridden patients, such as paraplegics. When inflated, these air mattresses are exceptionally soft and thick, significantly improving patient comfort. Compared to traditional mattresses, they are more effective in preventing and treating bedsores. Their primary advantage lies in their softness and sufficient thickness, which evenly distributes pressure across bony prominences.

[0004] However, this type of air mattress has certain defects, mainly because the large contact surface leads to poor air permeability, which makes it difficult to effectively ventilate and breathe the bedsore area or the surrounding area.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0006] In view of the problems in the related art, the present invention proposes an inflatable air cushion for medical use in treating bedsores to overcome the above-mentioned technical problems in the existing related art.

[0009] Furthermore, in order to enable patients with bedsores to stay dry and comfortable during use under the action of the auxiliary pad, reduce skin problems caused by moisture, and further promote the recovery of patients with bedsores, the auxiliary pad includes a breathable layer arranged at the top of several Velcro strips, a waterproof layer is arranged on the outside of the breathable layer, and an annular groove is opened between the waterproof layer and the breathable layer.

[0010] Furthermore, in order to ensure the breathability of the breathable layer, a multi-layer structure design is adopted, and each layer plays its own role, which not only ensures breathability but also provides softness and anti-slip properties, thereby helping to protect the skin of patients with bedsores. The breathable layer is composed of a breathable mesh fabric layer, a cotton wool layer, an elastic foam layer and a bottom layer of anti-slip material arranged in sequence from top to bottom. A plurality of breathable holes are evenly opened on the surface of the breathable mesh fabric layer.

[0011] Furthermore, in order to effectively prevent liquid penetration while maintaining breathability, ensuring the dryness of the air cushion and the safety of patients with bedsores, the waterproof layer is composed of a waterproof and breathable membrane, a composite fabric layer and a protective bottom layer arranged in sequence from top to bottom.

[0012] The beneficial effects of the utility model are:

[0023] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. By referring to these contents, ordinary technicians in this field should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0024] According to an embodiment of the present utility model, an inflatable air cushion for treating bedsores is provided.

[0025] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. Figure 1-Figure 5 As shown, the inflatable air cushion for treating bedsores according to the embodiment of the utility model includes an air cushion body 1, and an inflation and deflation interface 2 is provided on one side of the top of the air cushion body 1; a plurality of Velcro 1s 3 are evenly provided on the surface of the air cushion body 1, and Velcro 1s 3 are provided on the top of the Velcro 1s 3 to match them, and auxiliary pads 5 are provided on the top of the plurality of Velcro 2s 4, and an inflatable pillow pad 6 is provided on one side of the top of the air cushion body 1.

[0026] With the help of the above technical solution, the utility model facilitates the installation and disassembly of the auxiliary pad 5 through the cooperation of Velcro 1 3, Velcro 2 4 and the auxiliary pad 5. It can not only adjust the hardness and comfort of the air cushion according to the specific needs of the patients with bedsores, but also facilitate the cleaning and replacement of the auxiliary pad, thereby improving the flexibility and personalization of use; under the action of the auxiliary pad 5, the design of the auxiliary pad 5 takes into account the air permeability and waterproofness, so that the patients with bedsores can stay dry and comfortable during use, reduce skin problems caused by moisture, and further promote the recovery of patients with bedsores.

[0027] It needs to be explained that when in use, one end of the air tube is connected to the air pump and the other end is connected to the inflation and deflation interface 2, ensuring that the connection is not loose, and inflate the air cushion body 1 through the inflation and deflation interface 2. This is the existing technology and will not be described in detail here.

[0028] In one embodiment, for the above-mentioned auxiliary pad 5, the auxiliary pad 5 includes a breathable layer 501 arranged on the top of several Velcro strips 24, a waterproof layer 502 is arranged on the outside of the breathable layer 501, and an annular groove 503 is opened between the waterproof layer 502 and the breathable layer 501. Therefore, under the action of the auxiliary pad 5, patients with bedsores can stay dry and comfortable during use, reduce skin problems caused by moisture, and further promote the recovery of patients with bedsores.

[0029] In one embodiment, the breathable layer 501 is composed of a breathable mesh fabric layer 5011, a cotton wool layer 5012, an elastic foam layer 5013, and a non-slip material bottom layer 5014, arranged in order from top to bottom. A plurality of breathable holes 5015 are evenly distributed on the surface of the breathable mesh fabric layer 5011. Thus, under the action of the breathable layer 501, a multi-layer structure design is adopted, and each layer plays its own role, thereby ensuring breathability, providing softness and non-slip properties, and helping to protect the skin of patients with bedsores.

[0030] It should be explained that the breathable mesh fabric layer 5011 is made of fabric with a mesh structure, which allows air to circulate freely, helps to maintain air circulation inside the air cushion, reduces moisture and stuffiness, and provides a dry and comfortable sleeping environment for patients with bedsores. The mesh fabric is usually soft and skin-friendly, which can increase the comfort of patients with bedsores when in contact with the air cushion, reduce skin friction and discomfort, and the breathable mesh fabric layer 5011 usually has good wear resistance and tensile strength, can withstand friction and pulling in daily use, and extend the service life of the air cushion.

[0031] The cotton wool layer 5012 has good moisture absorption properties and can quickly absorb and store sweat and body fluids discharged by patients with bedsores, keeping the surface of the air cushion dry. Some cotton wool layers may have been specially treated to have antibacterial or antibacterial functions, which help to reduce bacterial growth and reduce the risk of infection. The cotton wool layer 5012 is soft and fits the skin, which can increase the comfort of patients with bedsores and reduce the skin pressure caused by long-term bed rest.

[0032] In addition, silver ions, nanosilver, chitosan, tea polyphenols and other ingredients with broad-spectrum antibacterial or antibacterial effects are added to the cotton wool layer 5012, which can effectively inhibit the growth of microorganisms such as bacteria and fungi and reduce the risk of infection, which is especially important for patients with bedsores.

[0033] The elastic foam layer 5013 has good resilience and can be adaptively adjusted according to the body shape and movements of the patient with bedsores, providing uniform support and reducing fatigue caused by prolonged bed rest. The pressure-relieving performance of the elastic foam layer 5013 helps to disperse body pressure and reduce pain and discomfort caused by local pressure, which plays an important role in preventing skin problems such as bedsores. The elastic foam layer 5013 can maintain the shape and stability of the air cushion and provide stable support even when the patient with bedsores turns over or moves.

[0034] The anti-slip material bottom layer 5014 is usually made of a material with anti-slip function, such as rubber or silicone, which can increase the friction between the air cushion and the bed surface, prevent the air cushion from sliding or shifting during use, and ensure the safety of patients with bedsores. The anti-slip material bottom layer usually has good wear resistance and can withstand friction and wear in daily use, thereby extending the service life of the air cushion.

[0035] In one embodiment, the waterproof layer 502 is composed of a waterproof breathable membrane 5021, a composite fabric layer 5022 and a protective bottom layer 5023 arranged in sequence from top to bottom, thereby effectively preventing liquid penetration while maintaining breathability, ensuring the dryness of the air cushion and the safety of patients with bedsores.

[0036] It needs to be explained that one of the main functions of the waterproof breathable membrane 5021 is to prevent moisture from penetrating from the outside to the inside of the air cushion, protect patients with bedsores from the intrusion of humid environments, and reduce skin problems caused by moisture accumulation. Despite its waterproof function, the waterproof breathable membrane still allows air and water vapor to pass through, which helps to maintain air circulation inside the air cushion, reduce the feeling of stuffiness, and improve the comfort of patients with bedsores. The waterproof breathable membrane usually has stable chemical properties and a wide temperature application range, and will not easily age or fail due to environmental changes.

[0037] The composite fabric layer 5022 is usually composed of multiple layers of fabric or a composite of fabric and other materials. It has high strength and wear resistance and can enhance the overall stability of the waterproof layer. According to different design requirements, the composite fabric layer can have multiple functions, such as anti-static, radiation protection, thermal insulation, etc., to further improve the comfort and safety of the air cushion. The composite fabric layer usually has good softness and skin-friendliness, which can increase the comfort of patients with bedsores when in contact with the air cushion.

[0038] The protective base layer 5023 usually has high wear resistance and can resist friction and wear in daily use, thereby extending the service life of the air cushion. Some protective base layers may also have an anti-slip function to ensure that the air cushion will not slide or shift during use, thereby improving the safety of patients with bedsores. The protective base layer provides a solid foundation for the entire waterproof layer, helping to maintain the shape and stability of the air cushion.

[0039] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.

[0040] In actual use, the air cushion body 1 is first inflated through the inflation and deflation interface 2 to adjust the hardness and support to the appropriate level. Based on the specific needs of the bedsore patient, the auxiliary pad 5 is attached to the air cushion body 1 using Velcro 1 3 and Velcro 2 4. The breathable and waterproof layers of the auxiliary pad 5 ensure that the patient with bedsores stays dry and comfortable during use, reducing skin problems. The inflatable pillow 6 provides head support for the patient, further enhancing comfort.

[0041] During use, if the auxiliary pad 5 needs to be cleaned or replaced, it can be easily removed and installed through Velcro 1 3 and Velcro 2 4; when the air cushion body 1 is no longer in use, the user can deflate it through the inflation and deflation interface 2 for storage and carrying.

[0042] To sum up, with the help of the above-mentioned technical scheme of the present invention, the present invention facilitates the installation and disassembly of the auxiliary pad 5 through the cooperation of Velcro 1 3, Velcro 2 4 and the auxiliary pad 5. It can not only adjust the hardness and comfort of the air cushion according to the specific needs of the patients with bedsores, but also facilitate the cleaning and replacement of the auxiliary pad, thereby improving the flexibility and personalization of use; under the action of the auxiliary pad 5, the design of the auxiliary pad 5 takes into account the air permeability and waterproofness, so that patients with bedsores can stay dry and comfortable during use, reduce skin problems caused by moisture, and further promote the recovery of patients with bedsores.
