Description

Technical Field

[0001] This utility model belongs to the field of mattress technology, and more specifically, it relates to an anti-pressure sore mattress. Background Technology

[0002] With the acceleration of population aging, more and more patients need long-term bed rest for treatment or rehabilitation. For users who are bedridden in hospitals, nursing homes or at home for a long time, preventing pressure sores is an important aspect of improving their quality of life and prolonging their lifespan. Among these measures, mattresses play a particularly important role in preventing pressure sores.

[0003] Currently, most existing mattresses have poor breathability and water resistance. When patients lie flat on such mattresses for extended periods, the poor breathability and prolonged localized pressure can easily lead to pressure sores and phlegm buildup in the throat. Furthermore, if bedridden patients experience sweating or urinary incontinence, the poor water resistance of the mattress allows sweat or urine to easily seep into the mattress. Since most existing mattresses are heavy and difficult to clean, they easily breed bacteria, which can also cause skin ulcers and pressure sores over time. In addition, existing mattresses only provide a lying position for bedridden patients, making their function relatively limited. If a patient has a localized injury requiring elevation and support to prevent pressure sores and secondary damage to the wound, or if the patient needs manual support during side-lying or turning to clear phlegm and prevent pressure sores, additional pillows or cushions need to be placed on either side of the wound or under the lower back for elevation and support, resulting in low applicability.

[0030] To explain the technical content, objectives, and effects of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings. It should be noted that the terms "upper" and "lower" used in the following description refer to the attached drawings. Figure 1 The direction in the middle, the words "bottom" and "top" refer to the attached Figure 1 and Figure 4 The direction towards the geometric center of a specific component.

[0031] The most crucial concept of this invention lies in: The first DuPont Tyvek layer 3 enhances the breathability and waterproofness of the upper surface of the mattress core 1, allowing for washing or wiping only the upper surface, thus preventing pressure sores and facilitating cleaning; the upper breathable mesh layer 4, the first 3D cotton layer 5, and the lower breathable mesh layer 6 utilize the good breathability, quick-drying, and easy-to-clean properties of the breathable mesh and 3D cotton materials to improve the breathability of the internal support layer of the mattress core 1, further preventing pressure sores and facilitating cleaning; the breathable pad cover 2 enhances the overall… While ensuring breathability, it also prevents some sweat or water from dripping onto the upper surface of the mattress core 1, thus further protecting the mattress core 1, preventing pressure sores, and facilitating cleaning. The air cushion 13 and pillow 11 provide multiple functions, including auxiliary side-lying support and leg wound elevation support. The waterproof and breathable layer 12 further prevents pressure sores. The connecting strap 8, front fixing strap 9, rear fixing strap 10, support core layer 16, short Velcro strap 14, and long Velcro strap 15 serve to fix the air cushion 13 and pillow 11 to the mattress core 1 and allow for adjustable position of the pillow 11.

[0032] This utility model has good overall breathability and waterproofness, preventing sweat, water or urine from penetrating into the interior of the bed core 1. It adds multiple functions such as auxiliary side-lying support and wound elevation support. Overall, it has the advantages of preventing pressure sores, multi-functionality and easy cleaning.

[0033] Reference Figures 1 to 7 The first embodiment provided by this utility model is as follows:

[0034] An anti-pressure ulcer mattress includes a core 1, side straps 7, and a breathable pad cover 2 that covers the outside of the core 1. The side straps 7 are arranged around the four sides of the core 1. The core 1 includes a first DuPont Tyvek layer 3, an upper breathable mesh layer 4, a first 3D cotton layer 5, a lower breathable mesh layer 6, and a bottom support layer, connected sequentially from top to bottom. The upper breathable mesh layer 4 and the lower breathable mesh layer 6 are connected by the side straps 7. The breathable pad cover 2 is covered with connecting straps 8, front fixing straps 9, and back fixing straps 10. The front fixing straps 9 and the back fixing straps 10 are all... A set of cushions 11 for supporting the patient's legs is detachably connected. A waterproof and breathable layer 12 is connected to the upper surface of the cushions 11. An air cushion 13 for supporting the patient's back is detachably connected to the connecting strap 8. Short Velcro straps 14 are connected to both sides of the connecting strap 8, the front fixing strap 9, and the rear fixing strap 10. A long Velcro strap 15 for attaching the short Velcro straps 14 is installed on both sides of the side strap 7 along the length of the bed core 1. A support core layer 16 is provided inside the connecting strap 8, the front fixing strap 9, and the rear fixing strap 10.

[0035] As described above, the first DuPont Tyvek layer 3 utilizes the breathable yet waterproof, antibacterial, and anti-mite properties of DuPont Tyvek material to prevent sweat and water from penetrating from the upper surface of the mattress core 1 into its interior, effectively protecting the skin from harm. While improving the breathability and waterproofness of the upper surface of the mattress core 1, when it is necessary to clean sweat, water, or urine from the upper surface of the mattress core 1, only a cotton cloth or tissue is needed to wipe it, thus preventing pressure sores and facilitating cleaning of the mattress core 1 surface. The upper breathable mesh layer 4 and the lower breathable mesh layer 6 utilize the good breathability of the mesh to improve the internal breathability of the mattress core 1 while reducing the first 3D... The friction between the upper and lower surfaces of the cotton layer 5 and the first DuPont Tyvek and the bottom support layer further prevents pressure sores and protects the first 3D cotton layer 5. The first 3D cotton layer 5 utilizes the excellent breathability, resilience, support, easy cleaning, and quick-drying properties of 3D cotton material to improve the breathability of the mattress core 1, ensure pressure sore prevention, and facilitate cleaning. The breathable mattress cover 2 prevents damage to the mattress core 1 from impacts or dust accumulation. When encountering heavy sweating or urine leakage, only the mattress cover needs to be replaced, without replacing the entire mattress, further improving overall breathability, preventing pressure sores, and facilitating cleaning.

[0036] When the side-lying back support or leg wound support function is needed, the air cushion 13 or the pillow 11 can be used alone to support the patient's back and both sides of the leg wound respectively. Alternatively, the air cushion 13 can be installed on the connecting strap 8, with one side of the connecting strap 8 passing through the gap between the patient's back and the surface of the bed core 1, and then attached to the bed core 1 by the short Velcro strap 14 of the connecting strap 8 and the long Velcro strap 15 of the side strap 7, so that the connecting strap 8 can be detachably fixed to the bed core 1, reducing the probability of the air cushion 13 shifting. The pillow 11 can also be installed on the front fixing strap 9 or the rear fixing strap 10 to slightly elevate the legs. Move the front fixing strap 9 and the rear fixing strap 10 along the length of the bed core 1 until the pillow 11 on the front fixing strap 9 and the pillow 11 on the rear fixing strap 10 are adjusted to the lower front and rear sides outside the leg wound. Then, attach the short Velcro strap 14 of the front fixing strap 9 and the short Velcro strap 14 of the rear fixing strap 10 to the corresponding positions on the long Velcro strap 15 to fix the pillow 11 in place on the bed core 1, reducing the probability of the pillow 11 shifting. Place the leg on top of the pillow 11 to avoid secondary damage to the wound and pressure sores, thus achieving the function of elevating and supporting the leg wound and preventing pressure sores.

[0037] While inflating the air cushion 13 using an external air pump, the patient can be manually or with the aid of a turning aid to perform assisted side-lying turning, making turning faster and less strenuous. The inflated air cushion 13 supports the patient's back, preventing pressure sores caused by prolonged supine lying, thus achieving the functions of assisted side-lying support and pressure sore prevention. The waterproof and breathable layer 12 prevents sweat and water from penetrating into the pillow 11, preventing mold growth inside the pillow 11. When cleaning the upper surface of the pillow 11, only a manual wiping with a cloth or tissue is required, further preventing pressure sores and facilitating cleaning. Supporting core layers 16 are set in the front and rear fixing straps 10 and the connecting strap 8 to increase the overall rigidity of the front fixing strap 9, rear fixing strap 10 and connecting strap 8, preventing the pillow or air cushion 13 from shifting due to the connecting strap 8, front fixing strap 9 and rear fixing strap 10 being too soft.

[0038] In this embodiment, the breathable mesh layer is a mesh fabric layer, but it is not limited to this type of mesh structure. Other mesh structures, such as yarn mesh or abrasion-resistant elastic mesh, are also acceptable, as long as they have the advantages of good breathability and washability.

[0039] Furthermore, the front fixing strap 9 includes a second DuPont Tyvek layer 17 and a first high-density breathable knitted quilted cotton layer 18 arranged from top to bottom; the support core layer 16 is a middle 3D mesh fabric layer and is connected between the second DuPont Tyvek layer 17 and the first high-density breathable knitted quilted cotton layer 18. The structural composition of the rear fixing strap 10 and the connecting strap 8 are the same as those of the front fixing strap 9. Both the rear fixing strap 10 and the connecting strap 8 are composed of the second DuPont Tyvek layer 17, the middle 3D mesh fabric layer and the first high-density breathable knitted quilted cotton layer 18 connected from top to bottom.

[0040] As described above, the second DuPont Tyvek layer 17 utilizes the waterproof and breathable properties of DuPont Tyvek material to prevent sweat or water from penetrating from the upper surface of the front fixing strap 9 into the interior of the front fixing strap 9 or the upper surface of the bed core 1. The intermediate 3D mesh fabric layer utilizes the advantages of good support, elasticity, and breathability of the 3D mesh fabric to further improve the breathability and support of the front fixing strap 9, and further ensure the fixation of the front fixing strap 9. The rear fixing strap 10 and the connecting strap 8 have the same composition and structure as the front fixing strap 9, and their composition and function are the same as those of the front fixing strap 9.

[0041] Furthermore, the pillow 11 includes an upper mesh layer 19, a latex cotton layer 20, a lower mesh layer 21, and a skin-friendly knitted fabric layer 22 connected sequentially from top to bottom. The pillow 11 is surrounded by edging 23 on all four sides. The waterproof and breathable layer 12 is a third DuPont Tyvek layer, which is connected to the upper surface of the upper mesh layer 19. A first waterproof and breathable membrane 24 is connected inside the edging 23 and inside the skin-friendly knitted fabric layer 22. The skin-friendly knitted fabric layer 22 and the third DuPont Tyvek layer are connected by the edging 23.

[0042] As can be seen from the above description, the upper surface (i.e., the front) and lower surface (i.e., the back) of the pillow 11 are respectively made of a third DuPont Tyvek layer and a skin-friendly knitted fabric layer 22. The DuPont Tyvek material has the characteristics of being breathable but not water-permeable, antibacterial and anti-mite, which improves the waterproof and breathable properties of the upper surface of the pillow 11. The skin-friendly knitted fabric layer 22 has the characteristics of being skin-friendly, soft and warm, providing users with a warm and comfortable, breathable and comfortable environment for supporting and elevating the legs for wounds. This realizes the function of the pillow 11 being reusable on both sides according to the season, further preventing pressure sores and making it easy to clean the pillow 11.

[0043] Through the upper mesh layer 19 and the lower mesh layer 21, the good breathability of the mesh layer ensures the breathability of the inside of the pillow 11. At the same time, when using the skin-friendly knitted fabric layer 22 on the reverse side of the pillow 11, it further reduces the rate of sweat and moisture continuing to settle into the pillow 11, and reduces the friction between the latex cotton layer 20 and the skin-friendly knitted fabric layer 22, which further helps to prevent pressure sores. Through the latex cotton layer 20, the good breathability and support of latex cotton further improve the breathability and support stability of the pillow 11, achieving the functions of preventing pressure sores and ensuring the function of supporting and elevating the legs. Through the first waterproof and breathable membrane 24, sweat and water are prevented from entering the interior of the pillow 11 from the four sides and the lower surface.

[0044] Furthermore, the bottom support layer is the fourth DuPont Tyvek 25 layer.

[0045] As described above, the bottom support layer uses the fourth DuPont Tyvek 25 layer, enabling the bed core 1 to be used on both sides and to be breathable and waterproof. The bottom support layer is in direct contact with the human body. Because DuPont Tyvek material has the advantages of being waterproof and breathable, it ensures the breathability and waterproofness of the bottom surface of the bed core 1. When it is necessary to clean the sweat and water on the bottom support layer, it is only necessary to wipe it with a cotton cloth or tissue, which further prevents pressure sores and facilitates cleaning.

[0046] Furthermore, the vertical cross-section of the air cushion 13 is set in a right-angled triangle. The air cushion 13 is provided with a first inflation port 36, and the first inflation port 36 is provided with a sealing cover 37. The two sides of the side strap 7 are detachably connected to storage bags 38 for storing the front fixing strap 9, the rear fixing strap 10, the connecting strap 8, the cushion 11 and the air cushion 13. The opening of the storage bag 38 is sealed by a zipper.

[0047] As described above, the air cushion 13 is designed with a right-angled triangle in its vertical cross-section. The sloping surface of the air cushion 13 provides better support for the patient's back. When inflation is needed, simply open the sealing cover 37 and use an external air pump to inflate the air cushion 13 through the first inflation port 36. The storage bag 38 is used to store the deflated air cushion 13, the pillow 11, the front fixing strap 9, the rear fixing strap 10, and the connecting strap 8, preventing the front fixing strap from collapsing when not in use. The fixing strap 9, back fixing strap 10, connecting strap 8, air cushion 13, and pillow 11 occupy a large area of ​​the upper surface of the bed core 1, which affects the user's lying comfort. The storage bag 38 can also be used to store small items such as mobile phone charging cables or earphones. The opening of the storage bag 38 is set to be sealed with a zipper to prevent the items inside the storage bag 38 from falling out. When it is necessary to take out or put in the items inside the storage bag 38, simply unzip the storage bag 38 to open it, ensuring that the storage bag 38 can be stored when the bed core 1 is used on both sides.

[0048] In addition, to ensure that the storage bags 38 can be stored when the bed core 1 is used on both sides, in addition to setting the opening of the storage bag 38 to be sealed with a zipper, the opening of the storage bag 38 can also be set to be open, with the storage bags 38 on both sides of the side strap 7 having the opening of the storage bag 38 on one side of the side strap 7 facing upwards and the opening of the storage bag 38 on the other side of the side strap 7 facing downwards, not limited to the above methods.

[0049] Furthermore, the storage bag 38 is also equipped with two sets of airbags 39 for supporting and elevating the patient's arm. Each set of airbags 39 has at least two airbags, and each airbag 39 has a second inflation port with a sealing plug 40.

[0050] As described above, when it is necessary to elevate and support the patient's arm wound, the sealing plug 40 is opened, and the airbag 39 is inflated through the second inflation port using an external air pump. After inflation, the sealing plug 40 is reinserted into the second inflation port to seal the inflated airbag 39. The inflated airbag 39 is then placed on both sides of the patient's arm wound to elevate and support it, preventing secondary injury or pressure sores. When the airbag 39 is no longer needed, the sealing plug 40 is opened to deflate the airbag 39, and the deflated airbag 39 is then placed back into the storage bag 38.

[0051] Furthermore, two connecting fabrics 41 are connected to both sides of the side strip 7, and a first buckle 42 is connected to both ends of the connecting fabric 41. A third waterproof and breathable membrane is connected to the middle surface of the breathable pad cover 2. A first female buckle 44 that cooperates with the first buckle 42 is connected to the inner edge of both sides of the breathable pad cover 2. Two long Velcro straps 15 are provided on the same side of the side strip 7. The two connecting fabrics 41 on the same side are located between the two long Velcro straps 15. Two protective fabrics 45 are provided on both sides of the side strip 7. The side of the long Velcro strap 15 away from the connecting fabric 41 is connected to the side of the protective fabric 45. A second buckle 46 is connected to both ends of the long Velcro strap 15. A second female buckle 47 that cooperates with the second buckle 46 is connected to both ends of the protective fabric 45.

[0052] As described above, when it is necessary to fix the breathable mattress cover 2, simply fasten the first female buckle 44 of the breathable mattress cover 2 with the first male buckle 42 of the connecting fabric 41 to achieve the function of detachably fixing the breathable mattress cover 2 to the bed core 1; when it is necessary to use the auxiliary side-lying support function and the wound elevation support function, first take out the connecting strap 8, the front fixing strap 9, the rear fixing strap 10, the pillow 11 and the air mattress 13 from the storage bag 38, then fix the breathable mattress cover 2, and then stick the short Velcro strap 14 to the long Velcro strap 15. After positioning, the protective cloth 45 is flipped over to cover the long Velcro strap 15. The long Velcro strap 15 and the protective cloth 45 are connected by the second male buckle 46 and the second female buckle 47 to protect the long Velcro strap and prevent foreign objects from adhering to the long Velcro strap 15, affecting its subsequent use. In addition, the third waterproof and breathable membrane improves the waterproof and breathable properties of the breathable pad cover 2. When cleaning the mattress, the entire pad cover can be washed, or it can be wiped dry with a cotton cloth or paper towel, further preventing pressure sores and facilitating cleaning.

[0053] Furthermore, a locking element 49 and a protective strip 48 for covering the locking element 49 are installed on the bottom surface of the cushion 11. The upper surfaces of the front fixing strip 9 and the rear fixing strip 10 and the bottom surface of the protective strip 48 are all connected to a fastener 50 that cooperates with the locking element 49. The locking element 49 is a hook and loop fastener (not shown in the figure) or a third female buckle, and the fastener 50 is a loop fastener (not shown in the figure) or a third female buckle.

[0054] As described above, when one or more cushions 11 need to be detachably installed on the front fixing strap 9 or the rear fixing strap 10, simply attach or fasten the locking piece 49 of the cushion 11 to the fixing piece 50 of the front fixing strap 9 or the rear fixing strap 10 to achieve the function of detachably installing the cushion 11 on the front fixing strap 9 or the rear fixing strap 10; when the cushion 11 needs to be disassembled for storage or used separately, simply detach the hook side of the cushion to be disassembled from the attached hook and loop fasteners. The surface can be separated, or the third male buckle of the pillow 11 can be detached from the third female buckle; when the pillow 11 is used alone, the protective tape 48 is placed over the locking part 49 of the pillow 11. The fixing part 50 of the protective tape 48 and the locking part 49 of the pillow 11 are glued or fastened together, which can cover the locking part 49 of the pillow 11 and prevent the locking part 49 of the pillow 11 from directly contacting or rubbing back and forth with the breathable pad 2, which would cause damage or pilling to the breathable pad 2.

[0055] The locking element 49 and the fixing element 50 are not limited to the above structure. Other structures are also acceptable, such as installing multiple binding ropes (not shown in the figure) on the bottom end face of the pillow 11 as locking elements 49, and opening fixing holes (not shown in the figure) on the front and rear fixing straps 10 for binding ropes to pass through and be tied and fixed as fixing elements 50. Any structure that can achieve a detachable connection between the pillow 11 and the front fixing strap 9 and between the pillow 11 and the rear fixing strap 10 is acceptable.

[0056] Another solution in this embodiment, such as Figure 6 As shown, in order to enable the pillow 11 to be detachably fixed at multiple locations along the width direction of the bed core 1, the fixing parts 50 of the front fixing strap 9 and the fixing parts 50 of the rear fixing strap 10 can be set in multiple sets along the width direction of the bed core 1 (i.e., the length direction of the front fixing strap 9 or the rear fixing strap 10). The protective strap 48 can be used to cover other fixing parts 50 that are not connected to the locking part 49.

[0057] Furthermore, a set of rubber protrusions 43 arranged around the four sides of the bed core 1 are installed on the upper and lower ends of the bed core 1.

[0058] As can be seen from the above description, the rubber protrusions 43 are used to increase the friction between the upper and lower surfaces of the bed core 1 and the upper surface of the bed board, so as to prevent the bed core 1 from moving during use, ensure that the bed core 1 can be placed more firmly on the bed board, and reduce the probability of the bed core 1 shifting.

[0059] Example 2 differs from Example 1 in that, as Figure 8 As shown, the bottom support layer is a second high-density breathable knitted quilted cotton layer 26.

[0060] As can be seen from the above description, in this embodiment, only the upper surface of the mattress core 1 uses the first DuPont Tyvek layer 3, and the bottom support layer uses the second high-density breathable knitted quilted cotton layer 26, which is not waterproof but has good breathability. This can prevent sweat, water or urine from penetrating the inside of the mattress core 1 while maximizing comfort and breathability. For some users who sweat less and do not have urinary incontinence, the mattress core 1 can be turned over and used with the bottom support layer facing up. Taking advantage of the high-density breathable knitted fabric's good moisture absorption and breathability, when the air humidity is high or sweat drips, the second high-density breathable knitted quilted cotton layer 26 will release the absorbed water or sweat, reducing the rate of sweat and water continuing to settle into the mattress body, thereby further improving the breathability and applicability of the mattress core 1.

[0061] Example 3 differs from Examples 1 and 2 in that, as follows: Figure 9 and Figure 10 As shown, the bottom surface of the bed core 1 is provided with a groove 27. A movable pad 28 for supporting the user's buttocks area is detachably connected inside the groove 27. The movable pad 28 includes a fifth DuPont Tyvek layer 29, an upper 3D mesh fabric layer 30, a second 3D cotton layer 31, a lower 3D mesh fabric layer 32, and a sixth DuPont Tyvek layer 33 connected from top to bottom. The movable pad 28 is connected to four sides with a rim 34, and a second waterproof and breathable membrane 35 is connected to the outside of the rim 34. There are at least two movable pads 28. In this embodiment, the movable pad 28 and the groove 27 can be detachably connected by Velcro, but it is not limited to this connection method. Other detachable connection methods such as buckles or zippers are also acceptable, as long as they can achieve the detachable connection between the movable pad 28 and the groove 27. To facilitate the removal and placement of the movable pad 28, a pull strap or pull rope can be provided on one side of the movable pad 28.

[0062] As described above, when a user experiences urinary incontinence or lower body discomfort, the bed core 1, which comes into contact with the buttocks area (from the lower back to the upper thigh), is prone to moisture. During use, the bed core 1 is flipped over, with the bottom support layer directly contacting the body, and the user's buttocks directly contacting the movable pad 28. When the movable pad 28 becomes dirty or wet and needs to be replaced and cleaned, simply remove the movable pad 28 from the groove 27 and install another clean movable pad 28 in the groove 27. There is no need to clean the entire bed core 1, ensuring the patient's buttocks remain dry and breathable, preventing pressure sores. The fifth DuPont Tyvek layer 29, the sixth DuPont Tyvek layer 33, and the second waterproof and breathable membrane 35 prevent urine, sweat, or water from seeping into the movable pad 28, ensuring its waterproof and breathable properties and further preventing pressure sores. When cleaning the surface of the movable pad 28, it can be wiped clean with a cotton cloth or tissue without disassembly, further facilitating cleaning.

[0063] Example 4 differs from Example 1 in that, as Figure 11As shown, two connecting fabrics 41 are provided on both sides of the side strip 7. A set of first male buckles 42 are connected to both ends of the connecting fabrics 41. The inner edges of both sides of the breathable pad cover 2 and both ends of the long Velcro strap 15 are connected to first female buckles 44 that cooperate with the first male buckles 42. Two long Velcro straps 15 are provided on the same side of the side strip 7. The two connecting fabrics 41 on the same side are located between the two long Velcro straps 15. The side of the connecting fabric 41 closest to the long Velcro strap 15 is connected to the side strip 7. The other three sides of the connecting fabric 41 are detachably connected to the side strip 7 by a zipper. The long Velcro strap 15 is the Velcro loop side, and the short Velcro strap 14 is the Velcro hook side. The air cushion 13 is shown in a flat state without being deflated.

[0064] As described above, the first female buckle 44 and the first female buckle 42 of the breathable pad cover 2 are interlocked, enabling the breathable pad cover 2 to be detachably connected to the two sides of the side strap 7. This ensures that the breathable pad cover 2 is detachably fixed to the bed core 1 and prevents it from shifting on the bed core 1. When the auxiliary side-lying support function and wound elevation support function are needed, first take out the connecting strap 8, front fixing strap 9, rear fixing strap 10, pillow 11 and air cushion 13 from the storage bag 38, then put on the breathable pad cover 2, and then stick the short Velcro strap 14 to the corresponding position on the long Velcro strap 15. When the long Velcro strap 15 and the breathable pad cover 2 are not needed, separate the first female buckle 44 of the breathable pad cover 2 from the first male buckle 42 of the connecting fabric 41, then unzip the zippers on the other three sides of the connecting fabric 41, and then fasten the first male buckle 42 of the connecting fabric 41 with the first female buckle 44 of the long Velcro strap 15 to prevent foreign objects from adhering to the long Velcro strap 15, thus protecting the long Velcro strap 15; using the long Velcro strap 15 as the Velcro loop side prevents accidental injury when people are tidying the side straps 7 of the bed core 1 or getting out of bed.

[0065] The first waterproof and breathable membrane 24, the second waterproof and breathable membrane 35, and the third waterproof and breathable membrane in the above embodiments can all be TPU waterproof and breathable membranes; the waterproof and breathable structure is not limited to this material, and other waterproof and breathable materials such as DuPont Tyvek, polytetrafluoroethylene, or PTFE microporous membranes can also be used to make waterproof and breathable membranes; waterproof and breathable membranes are well known to those skilled in the art, and the components of the listed TPU waterproof and breathable membranes will not be described in detail here.

[0066] In summary, compared with existing technologies, this utility model has the advantages of preventing pressure sores, multifunctionality, and ease of cleaning. Through the first DuPont Tyvek layer 3, utilizing the breathable, waterproof, antibacterial, and anti-mite properties of DuPont Tyvek material, it provides users with comfort and breathability while preventing sweat, water, or urine from penetrating into the interior of the mattress core 1. Furthermore, when encountering sweat, water, or urine on the upper surface of the mattress core 1, it can be washed with water or simply wiped with cotton cloth or tissue, thus improving the breathability, waterproofness, pressure sore prevention, and ease of cleaning of the mattress core 1. Through the upper breathable mesh layer 4, the first 3D cotton layer 5, and the lower breathable mesh layer 6, utilizing the good breathability of the breathable mesh layer and the excellent breathability, resilience, and support of the 3D cotton material, as well as its easy-to-clean and quick-drying properties, it further enhances the mattress core 1's breathability and waterproofness. The bed core 1 provides breathability, further prevents pressure sores, and facilitates cleaning. The breathable pad cover 2 improves overall breathability while preventing some sweat or water from dripping onto the upper surface of the bed core 1. Cleaning only requires replacing the breathable pad cover 2, further preventing pressure sores and facilitating cleaning. The air cushion 13 and pillow 11 are used to elevate and support the back and leg wounds during side-lying positions, respectively, providing auxiliary side-lying support and wound elevation support. The waterproof and breathable layer 12 further prevents pressure sores. The connecting strap 8, front fixing strap 9, rear fixing strap 10, support core layer 16, short Velcro strap 14, and long Velcro strap 15 allow for the detachable fixing of the air cushion 13 and pillow 11 to the bed core 1, while the position of the pillow 11 can be adjusted and fixed along the length of the bed core 1.
