Abstract
Description
Technical Field
[0001] The invention relates to the technical field of mattresses, in particular to an anti-bedsore mattress assembly with an air core structure. Background Art
[0002] A mattress is an item between the human body and the bed frame, usually composed of a fabric layer, a filling layer and a support layer. The mattress can provide good support for the human body and keep the body in a natural physiological curve during sleep. Especially for the spine, a suitable mattress can reduce the pressure on the spine and prevent and relieve spinal diseases.
[0003] The anti-bedsore mattress is a special mattress that is mainly used to prevent and relieve bedsores. Bedsores, also known as pressure sores, are caused by long-term pressure on local tissues of the body, which hinders blood circulation and leads to tissue damage and necrosis caused by lack of nutrition in the skin and subcutaneous tissues. The anti-bedsore mattress reduces the risk of bedsores by redistributing body pressure and reducing local pressure concentration.
[0004] However, at present, 1. Most of the current mattresses are one-piece structures, but in daily use, sweat, oil, etc. will be secreted during sleep, and these secretions will penetrate through the sheets to the layer closest to the human body surface. Over time, stains will form and are difficult to clean; 2. Some mattresses may adjust the softness and hardness by inflating or deflating the internal air bags through an air pump, but this adjustment is a fixed mode, and the existing non-adaptive adjustment mattresses cannot automatically sense these changes and make corresponding pressure adjustments, resulting in the inability to provide the best pressure distribution in certain sleeping positions, affecting comfort and anti-bedsore effects; 3. Most anti-bedsore mattresses are used by the elderly. For a specific user group, the single pressure adjustment function often cannot play a comprehensive care role and cannot meet people's usage needs well. Summary of the invention

[0018] The present invention provides an anti-bedsore mattress assembly with an air core structure, which has the following beneficial effects:
[0019] The anti-bedsore mattress assembly with an air core structure can be adaptively adjusted according to the pressure distribution and posture changes of different parts of the human body through the nested structure of outer air bags, middle air bags and inner air bags. After the weight of the human body acts on the outer air bags, its pressure is transmitted to the middle and inner air bags in turn. Each layer of air bags, by virtue of its own shape characteristics and connecting channels, allows the gas to flow rapidly between the air bags, achieving uniform pressure dispersion from coarse adjustment to fine adjustment. Whether lying on your back, side, or turning over, it can effectively avoid excessive local pressure, provide continuous, stable and uniform support for the human body, and greatly improve the comfort and anti-bedsore performance of the mattress.
[0020] The anti-bedsore mattress assembly with an air core structure has a metal frame material that ensures that the entire mattress has sufficient supporting strength to withstand the weight of the human body and the pressure in various usage scenarios. The grid-like hollow design effectively reduces the weight of the frame, making it convenient to carry and install the mattress. At the same time, it is beneficial for the exchange of air around the body with the outside world during use, keeping the inside of the mattress dry, reducing stuffiness and moisture accumulation, and creating a comfortable sleeping environment for users. The rotating structure of the bogie can realize the angle change at both ends of the mattress main structure. For long-term bedridden people or rehabilitation patients, the angle can be adjusted according to different rehabilitation needs.
[0021] The anti-bedsore mattress assembly with an air core structure has an internal structure of the delivery port that not only ensures that the internal gas will not leak, but also prevents the anti-overflow tube from falling off when the air bag is pressurized. At the same time, the through hole at the axis can also conveniently use an external air pump to inflate the internal air bag, achieving a good balance between sealing, connection stability and inflation convenience, ensuring the normal operation and maintenance convenience of the mattress air bag system.
[0022] The anti-bedsore mattress assembly with an air core structure has a heart rate sensor and a breathing sensor arranged at the position where the surface of the latex layer and the bottom of the surface layer fit together, and an identification position is set on the surface of the surface layer corresponding to the sensor position. The heart rate sensor is close to the human heart, and the breathing sensor is located below the area where the chest rises and falls significantly and is set at multiple points. Such a layout can accurately sense the human heart rate and breathing conditions, effectively increase the reliability of data collection, avoid missing or inaccurate monitoring data caused by sleeping posture, and provide more comprehensive data support for the user's health status assessment, especially for the elderly, patients with chronic diseases or people who need special care.
[0023] The anti-bedsore mattress assembly with an air core structure has a surface layer and a base layer connected by convex buckles and concave buckles. This connection method makes the surface layer relatively easy to remove, avoiding the problem of difficulty in cleaning an integrated mattress, making it convenient for users to perform daily cleaning and maintenance, and extending the overall service life of the mattress. In addition, the convex buckles and concave buckles are located on the side, so when the user lies on the mattress, it will not cause discomfort such as rubbing on the body, thereby ensuring the lying comfort of the mattress.

The bag 8 is located between the sponge layer 7 and the latex layer 9, a middle-layer air bag 11 is arranged inside the outer air bag 8, an inner-layer air bag 12 is arranged inside the middle-layer air bag 11, one end of the outer wall of the material wrapping layer 10 is fixedly connected with a delivery port 13, an elastic connecting tube 14 is arranged on the side corresponding to the delivery port 13 inside the base layer 3, the delivery port 13 is connected to the outer air bag 8 through the elastic connecting tube 14, a convex buckle 15 is fixedly connected to the inner wall of the connecting side layer 5, and a concave buckle 16 for inserting the convex buckle 15 is fixedly connected to the outer wall of the material wrapping layer 10.
[0039] The skeleton 2 is composed of a middle fixed frame 201 and a bogie 202. The middle fixed frame 201 is located between the bogies 202, and the middle fixed frame 201 is rotatably connected to the bogie 202 at the corresponding end. The two ends of the inner wall of the support frame 1 are rotatably connected to the bottom of the bogie 202 respectively, and the gas spring telescopic rod 204 is located between the hydraulic cylinders 203.
[0040] The delivery port 13 is composed of an A joint 1301 and a B joint 1302, and the A joint 1301 is glued to the outside of the material wrapping layer 10, and the B joint 1302 is threadedly connected to the outside of the A joint 1301. A plug 1303 is opened at the axis of the A joint 1301, one end of the plug 1303 is inserted into the elastic connecting tube 14, and the other end of the plug 1303 is inserted and connected to the anti-overflow tube 1304, and the outer wall of the A joint 1301 is covered with a sealing strip 1305.
[0041] In this embodiment, Figure 2 and Figure 3 As shown, the middle fixing frame 201 and the bogie 202 are made of metal, and the inside of the middle fixing frame 201 and the bogie 202 is a grid-shaped hollow structure, and the middle fixing frame 201 is connected to the inner wall of the support frame 1 by bolts, and the tops of the middle fixing frame 201 and the bogie 202 are fixedly connected to the bottom of the material wrapping layer 10; the metal material of the frame 2 provides the support structure of the entire mattress, and the grid-shaped hollow structure can effectively reduce the weight of the entire frame 2, which is very beneficial for the transportation and installation of the mattress. At the same time, when a person lies on the mattress, the air around the body can be exchanged with the outside air through these hollow parts. This helps to keep the inside of the mattress dry and reduce the feeling of stuffiness and moisture accumulation.
[0042] In this embodiment, Figure 2 and Figure 3 As shown, the power output ends of the hydraulic cylinder 203 and the gas spring telescopic rod 204 are both rotatably connected to the bottom of the corresponding bogie 202, and the corresponding hydraulic cylinder 203 and the gas spring telescopic rod 204 located below the bogie 202 are distributed in opposite directions, and one end of the bogie 202 is formed by the hydraulic cylinder 203 to form a lifting structure, and the bogies 202 form relative motion; the base layer 3 and the surface layer 4 constitute the main structure of this mattress, and the base layer is coated with a material wrapping layer 10 on the outside, and the fixation with the skeleton 2 is achieved through the material wrapping layer 10. The rotating structure of the bogie 202 can realize the change of the angle of the two ends of the upper mattress main structure, which can prevent certain parts from being subjected to excessive pressure for a long time for bedridden people, and promote blood circulation. For example, in some rehabilitation scenarios, leg injuries or postoperative recovery stages, one end of the mattress can be adjusted to a suitable lifting angle through the bogie 202 to promote blood reflux, reduce swelling, and assist the rehabilitation treatment process, or according to one's own needs, in a semi-recumbent position, adjust the angles of the two ends of the mattress to obtain more comfortable support, thereby increasing the flexibility of the mattress in different life scenarios.
[0043] In this embodiment, Figure 5As shown, the elastic support members 6 are provided with several groups, which are equidistant and distributed in parallel, and the interior of the elastic support members 6 is composed of several springs and non-woven fabric wrapped on the outside, and a filling layer is provided in the gap inside the base layer 3 corresponding to the outside of the elastic support members 6; the upper airbag mainly provides support through the compressibility of the internal gas, and the elastic support member 6 provides supporting force by its elastic deformation, and the combination of the two forms a multi-level support system, and the presence of the spring can make the pressure distribution more uniform, reduce the wear and damage of the airbag, and thus extend the service life of the mattress, the non-woven fabric outside the elastic support member 6 reduces the wear of the spring on the top material, and the additional filling layer avoids the phenomenon of local depression or cavity in the mattress, making the mattress surface smoother.
[0044] In this embodiment, Figure 5 , Figure 6 and Figure 7 As shown, the outer airbags 8, the middle airbags 11 and the inner airbags 12 are distributed in a nested manner, and the outer airbags 8 are interconnected in pairs, and one group of the outer airbags 8 is connected to the delivery port 13 via an elastic connecting tube 14. At the same time, the number of the outer airbags 8 located in the middle of the base layer 3 is greater than the number at the two ends, and pressure sensors are provided at the positions corresponding to the outer airbags 8 in the base layer 3. Considering that most of the weight of the human body is concentrated in the middle, such as the waist and buttocks, more outer airbags 8 are distributed in the middle to better bear the weight of the body, so that the pressure is evenly dispersed in this key area, preventing the waist and buttocks and other parts from feeling uncomfortable or bedsores due to concentrated pressure, especially for people who are bedridden for a long time. Since the outer airbags 8 are interconnected in pairs, and one group is connected to the delivery port 13, the airbags can be inflated or deflated through the delivery port 13 according to the data fed back by the pressure sensor.
[0045] In this embodiment, Figure 6 and Figure 7 As shown, the middle airbag 11 is composed of a plurality of curved distribution structures arranged inside the outer airbag 8 located in the middle area of the base layer 3, and the middle airbag 11 is in the shape of an elongated strip with a depression in the middle, and the middle airbags 11 are interconnected, and at the same time, a middle airbag 11 adjacent to the inner wall of the outer airbag 8 is provided with a connecting tube made of the same material as the elastic connecting tube 14 but with a smaller diameter than the elastic connecting tube 14; the structural form of the middle airbag 11 enables it to better fit the curve of the human body, especially in the middle position such as the waist and buttocks of the human body. When a person lies on the mattress, the curved middle airbag 11 can be adaptively deformed according to the natural shape of the human body. When the human body applies pressure to the mattress, the pressure in the outer airbag 8 will be transmitted between the middle airbags 11 through the mutually interconnected channels, thereby avoiding excessive accumulation of pressure in local areas. When a single airbag structure is subjected to pressure, the pressure can only be dispersed to a limited extent inside the airbag, which is prone to local excessive pressure.
[0046] In this embodiment, Figure 7 As shown, the inner airbags 12 are pocket-shaped and interconnected and closely arranged inside the middle airbags 11, and the tops of the inner airbags 12 are provided with pipe openings that are interconnected with the middle airbags 11; when the human body contacts the mattress, the pressure first acts on the outer airbags 8, which, as the first layer of buffer structure, begins to perform preliminary deformation and gas regulation according to the pressure size and distribution, and then the pressure is transmitted to the middle airbags 11. The curved structure and interconnected characteristics of the middle airbags 11 enable it to further disperse and buffer the pressure in different directions, and finally the pressure reaches The inner airbag 12, when the human body posture changes slightly, the pressure in the local area will change accordingly, and at this time the gas can flow rapidly between the airbags with the help of these connecting channels. This rapid gas flow allows the shape of the airbag to be further fine-tuned, thereby achieving uniform pressure dispersion. Whether it is from supine to side-lying, or slight posture adjustments during side-lying, the airbag can adapt quickly and provide continuous, stable and uniform support for all parts of the human body. Compared with the traditional single airbag, this nested combination of airbags has the significant advantage of adaptive pressure regulation.
[0047] In this embodiment, Figure 5 and Figure 8 As shown, a through hole for connecting the elastic connecting tube 14 and the plug 1303 is provided at the position of the base layer 3 corresponding to the delivery port 13, and the anti-overflow tube 1304 is made of silicone, and the other end of the anti-overflow tube 1304 is tightly fitted to the inner wall of the B connector 1302; the plug-in connection between the plug 1303 and the anti-overflow tube 1304 effectively avoids the phenomenon of internal gas leakage, and when the airbag is under pressure, since the anti-overflow tube 1304 is tightly fitted to one end of the B connector 1302, and the threaded structure of the B connector 1302 and the A connector 1301 effectively avoids the problem of the anti-overflow tube 1304 falling off under pressure, and at the same time, a through hole is provided at the axis center, and the internal airbag can be inflated later with the help of an external air pump. Under the compatibility of the sealing and connecting structures, it does not affect the functions of gas leakage and component falling off, and realizes the convenience of inflation.
[0048] In this embodiment, Figure 8As shown, an annular structure is formed outward along the axis of the B connector 1302, and the outer wall of the annular structure and the corresponding inner wall of the B connector 1302 are both threaded structures, and a concave groove is provided on the outer wall of the A connector 1301 for threaded connection to the B connector 1302, and the inner wall of the groove and the outer wall of the A connector 1301 are threaded; the special shapes of the A connector 1301 and the B connector 1302 realize the internal and external thread connection mode, so that the two connectors are tightly combined together, which provides stability for the internal airbag assembly, and further plays an auxiliary sealing role combined with the external sealing strip 1305.
[0049] In this embodiment, Figure 1 , Fig. 9 and Fig.10 As shown, the convex buckles 15 are distributed in a ring shape on the side where the connecting edge layer 5 and the material wrapping layer 10 are in contact, and the surface layer 4 and the base layer 3 are connected by the convex buckles 15 and the concave buckles 16, and the heart rate sensor and the breathing sensor are respectively arranged at the position where the surface of the latex layer 9 and the bottom of the surface layer 4 are in contact, and at the same time, the position of the surface layer 4 corresponding to the sensor is provided with an identification position, one end of the outer wall of the support frame 1 is connected with a protective cover 17 through a zipper, and the support frame 1 is provided with a cavity at the position where the protective cover 17 is located, and a control mainboard and a display panel are arranged in the cavity; compared with an integrated mattress, when the mattress surface is stained or needs to be cleaned, the bottom layer 4 can be removed separately for cleaning, avoiding the integrated mattress. In order to solve the problem of difficult cleaning, a surface layer 4 is added and connected to the material wrapping layer 10 outside the base layer 3 by means of convex buckles 15 and concave buckles 16, so that the surface layer 4 can be relatively easily removed, and the convex buckles 15 and concave buckles 16 are located laterally. When the user lies on the mattress, it will not cause discomfort such as pressure on the body, thereby ensuring the comfort of the mattress. Considering the user population of the mattress, an additional heart rate sensor and a breathing sensor are added to monitor the user's heart rate and breathing conditions in real time, and an identification position is set at the position corresponding to the sensor on the surface of the surface layer 4, so that the user can understand the position of the sensor, which helps the user to place the body correctly and ensures that the sensor can accurately obtain heart rate and breathing data.
[0050] In summary, when the anti-bedsore mattress assembly with an air core structure is used, the user lies on the surface layer 4, and the body weight acts on the mattress surface layer 4, which is borne by the internal components of the base layer 3. When the human body lies on the mattress, the body weight first acts on the outer air bag 8. The outer air bag 8, as the first layer of air bag in direct contact with the human body, begins to receive pressure. Due to the uneven pressure distribution in different parts of the human body, for example, the pressure in the middle part of the human body (waist and buttocks) is relatively large, and the pressure in the shoulders and legs is relatively small. The outer air bag 8 located in the middle position of the base layer 3 will produce different degrees of deformation according to this pressure distribution. The outer air bag 8 in this area will be compressed more severely. After the outer air bag 8 is compressed, the pressure will be transmitted to the middle air bag 11. The middle air bag 11 11 will further disperse the pressure according to the pressure distribution of the outer airbag 8 and its own shape characteristics. For example, the curved middle airbag 11 will better adapt to the pressure change in the human body curve fitting area such as the waist and buttocks, and transmit the pressure in all directions. Since the middle airbags 11 are interconnected, the pressure between the middle airbags 11 will be evenly distributed like between the outer airbags 8. A middle airbag 11 adjacent to the inner wall of the outer airbag 8 is provided with a connecting tube that is the same material as the elastic connecting tube 14 but has a smaller diameter than the elastic connecting tube 14, so that gas exchange can be carried out between the middle airbag 11 and the outer airbag 8. When the pressure change of the outer airbag 8 causes gas to flow, the middle airbag 11 will pass through this connecting tube and its own interconnected channels to communicate with the outer airbag 8. The outer airbags 8 cooperate to adjust the pressure, and the pressure change of the middle airbag 11 will be further transmitted to the inner airbag 12. When the pressure is transmitted to the inner airbag 12, the inner airbag 12 will perform the final fine adjustment according to the pressure distribution of the middle airbag 11. For example, when the posture of the human body changes slightly and the local pressure changes, the pressure change of the middle airbag 11 causes the gas in the inner airbag 12 to flow rapidly through the pipe mouth, and the shape of the inner airbag 12 will be fine-tuned accordingly, so that the pressure is evenly dispersed in the innermost layer. This pressure transmission and redistribution process from the outer airbag 8 to the middle airbag 11 and then to the inner airbag 12 can effectively realize the adaptive adjustment of the mattress airbag system according to the pressure distribution and posture changes of the human body, and provide a comfortable and uniform mattress for the human body. At the same time, for long-term bedridden people or rehabilitation patients, the bogie 202 can be rotated by controlling the hydraulic cylinder 203 and the gas spring telescopic rod 204 to adjust the angles of the two ends of the mattress main structure. When stains appear on the mattress surface and need to be cleaned, the surface layer 4 can be removed from the material wrapping layer 10 outside the base layer 3 along the connection between the convex buckle 15 and the concave buckle 16 and washed separately. When the display device corresponding to the control panel shows that the internal pressure is insufficient, the B connector 1302 is removed from the surface of the A connector 1301 by rotation, and the internal outer airbag 8 is inflated with the help of an external wireless air pump (model DTDB-14), which is equipped with a small-caliber inflation nozzle, which is inserted through the through hole at the axis of the anti-overflow tube 1304. In actual sleeping scenes,During sleep, the posture of the human body changes dynamically, which may partially block or affect the normal operation of the sensor. The heart rate sensor (GH3018) is set near the human heart, and the respiratory sensor (NPC-1210-001G-3S) is placed below the heart where the chest rises and falls significantly. The multi-point setting can increase the redundancy of data collection and avoid missing or inaccurate monitoring data caused by sleeping posture. The heart rate and respiratory electrical signals collected by the sensor are transmitted to the control mainboard in the cavity of the support frame 1 through wires. After the control mainboard receives the signal from the sensor, the processed heart rate and respiratory data can be displayed on the connected display.
