Description

Technical Field

[0001] This utility model relates to the field of air bed technology, and in particular discloses a multi-layer lifting air bed. Background Technology

[0002] In scenarios such as emergency medical care, inter-hospital transfers, and special patient care, safe, comfortable, and easy-to-use patient transport equipment is crucial. Traditional patient transport tools, such as stretchers and ordinary hospital beds, have many limitations in practical use.

[0003] While stretchers are lightweight and easy to move quickly in narrow passages or stairwells, they lack sufficient cushioning and shock absorption during transport. When encountering uneven or bumpy surfaces, the patient's body will shift significantly with the swaying of the stretcher. This not only causes physical discomfort but may also worsen the patient's condition, especially for patients with spinal injuries, fractures, or other external injuries, potentially causing secondary damage due to the bumps. Furthermore, the simple structure of stretchers cannot provide stable support and a comfortable position for the patient, and prolonged use can easily lead to localized pressure on the patient's body, causing complications such as pressure sores.

[0004] While standard hospital beds provide patients with relatively stable support and a comfortable resting environment, they present numerous challenges during transport. Standard hospital beds are large and heavy, requiring multiple people to move them, which is not only labor-intensive but also extremely inconvenient in narrow spaces such as elevators and corridors. Furthermore, standard hospital beds lack adjustability, making it impossible to flexibly adjust the angle and height according to the patient's condition and transport needs, resulting in poor adaptability to certain special transport situations. Therefore, a multi-layer adjustable air bed is needed to solve these problems. Utility Model Content

[0005] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a multi-layer lifting air bed.

[0006] To achieve the above objectives, this utility model provides a multi-layer lifting air bed, including a first pad for supporting personnel, and a second pad on the first pad. Both the first and second pads are hollow. A connecting component is provided on the first pad, and the first pad is detachably mounted on the second pad via the connecting component. Both the first and second pads are provided with an air inlet valve and an air outlet valve, and the distances of the two air inlet valves from one end of the corresponding pad in the width direction are not equal.

[0007] Preferably, multiple second pads are provided, and multiple exhaust valves on the first and second pads are collinear and perpendicular to the upper end face of the first pad. The arrangement of multiple second pads increases the overall layering and adjustability of the air bed. The collinear arrangement of multiple exhaust valves perpendicular to the upper end face of the first pad allows gas to be discharged in an orderly manner in a specific direction, ensuring smooth gas discharge during the deflation process of the air bed, improving deflation efficiency, and also helping to ensure that the pad can shrink more flatly after deflation, making it easier to store and fold.

[0008] Preferably, the distances between the multiple air inlet valves and the corresponding air outlet valves on the first and second cushions are not equal, which realizes the uniform distribution of gas throughout the cushion, ensures that all parts of the cushion can expand synchronously, and improves the overall stability of the air bed.

[0009] Preferably, the air inlet valve is a one-way air inlet valve. The one-way air inlet valve only allows gas to enter the pad in one direction, preventing gas backflow and ensuring the smooth progress of the inflation process. This enables the air bed to be filled with gas quickly and stably during inflation, avoiding problems such as insufficient inflation or slow inflation caused by gas backflow, and improving inflation efficiency.

[0010] Preferably, both the air inlet valve and the air outlet valve are located on one side of the first and second pads, and are on the side of the first and second pads in the width direction. By placing the air inlet valve and the air outlet valve on the side of the pad, it is convenient for the user to operate during inflation and deflation. At the same time, it avoids the discomfort that the valve may cause to the user if it is located on the upper surface of the pad. This makes the inflation and deflation operation of the air bed convenient and improves the user comfort of the product.

[0011] Preferably, the first pad is further provided with a first extension member, which is located at both ends in the width direction of the first pad. The first extension member is provided with a limiting member and a traction member. The limiting member and the traction member are used to limit the patient and facilitate the user's traction, respectively. The provision of the first extension member increases the structural stability of the first pad. The limiting member can limit the patient and prevent the patient from moving freely on the air bed. The traction member facilitates the user to move or adjust the position of the air bed, realizing the safety and convenience of the air bed during use, improving the quality of patient care and the operational efficiency of the user.

[0012] Preferably, both the limiting component and the traction component are provided in two sets, with the two sets of traction components located between the two sets of limiting components. The arrangement of the two sets of limiting components and traction components can provide a more stable limiting and traction effect, making the air bed safer and more reliable when carrying patients. The traction component is located between the two sets of limiting components, which makes it easier for the user to maintain balance during traction. This achieves dual protection for the air bed in terms of limiting and traction, improving the overall performance and safety of the product.

[0013] Preferably, the limiting component includes a male and female straps disposed at both ends in the width direction of the first pad. The ends of the male and female straps are used to lock and limit the personnel carried on the first pad. The design of the male and female straps can be easily adjusted and locked according to the patient's body shape and needs, effectively preventing the patient from sliding or falling off the air bed, achieving reliable limiting of the patient, and improving the applicability and safety of the air bed in medical care and other scenarios.

[0014] Preferably, a second extension is provided at both ends of the first pad along its length. Both the first and second extensions are located on the first pad near the end used to support personnel. The second extensions are provided with identical traction components. The provision of the second extensions further increases the structural stability of the first pad and, together with the first extensions, forms a more complete support structure. The traction components on the second extensions facilitate the traction of the air mattress from different directions, thereby optimizing the structure and traction of the air mattress and improving the overall performance and flexibility of the product.

[0015] Preferably, the connecting component includes a first connector disposed on the second pad and a second connector disposed on the first pad. The second pad is disposed on the first pad via the connecting component. The design of the connecting component enables the detachable connection between the second pad and the first pad, which facilitates the combination and adjustment of the air bed according to actual needs. This enables multi-level combination and flexible use of the air bed, meeting the diverse needs of different scenarios and personnel for air bed height, comfort, and other aspects.

[0016] The beneficial effects of this utility model are as follows: Both the first and second pads are hollow and equipped with an inlet valve and an outlet valve, respectively. Their function is to provide inflation space for the pads. Gas can be injected into the pads through the inlet valve to cause expansion, and gas can be discharged through the outlet valve to cause contraction. This allows the pads to be inflated and deflated as needed, thereby adjusting the pad's firmness and height to adapt to different usage scenarios and user comfort requirements. A connecting component is provided on the first pad, and the first pad is detachably mounted on the second pad via the connecting component. This allows for a detachable connection between the first and second pads, facilitating individual use, replacement, or maintenance of both pads, thus improving the product's flexibility and convenience. The two inlet valves are not equidistant from one end of the corresponding pad's width direction. This prevents the inflation components from being unable to achieve synchronous inflation when inflated simultaneously, improving user comfort and inflation speed. Attached Figure Description

Both the first pad 1 and the second pad 7 are hollow. A connecting component 2 is provided on the first pad 1.

The distances of the two air inlet valves 9 from one end of the corresponding pad in the width direction are not equal.

[0026] Specifically, both the first pad 1 and the second pad 7 are hollow and equipped with an air inlet valve 9 and an air outlet valve 8, respectively. Their function is to provide inflation space for the pads. Gas can be injected into the pads through the air inlet valve 9 to cause expansion, and gas can be discharged through the air outlet valve 8 to cause contraction. This allows the pads to be inflated and deflated as needed, thereby adjusting the pads' firmness and height to suit different usage scenarios and user comfort requirements. A connecting component 2 is provided on the first pad 1, and the first pad 1 is detachably mounted on the second pad 7 via the connecting component 2. This allows for a detachable connection between the first pad 1 and the second pad 7, facilitating individual use, replacement, or maintenance of the two pads, thus improving the flexibility and convenience of product use. The two air inlet valves 9 are not equidistant from one end of the corresponding pad width. This prevents the inflation components from being unable to achieve synchronous inflation when inflated simultaneously, improving user comfort and inflation speed.

[0027] Specifically, multiple second pads 7 are provided. Multiple exhaust valves 8 on the first pad 1 and the second pad 7 are collinear and perpendicular to the upper end face of the first pad 1. The arrangement of multiple second pads 7 increases the overall layering and adjustability of the air bed. The collinear arrangement of multiple exhaust valves 8 perpendicular to the upper end face of the first pad 1 allows the gas to be discharged in an orderly manner in a specific direction, realizing the smoothness of gas discharge during the deflation process of the air bed, improving the deflation efficiency, and also helping to ensure that the pad can shrink more flatly after deflation, making it easier to store and fold.

[0028] Specifically, the distances between the multiple air inlet valves 9 and the corresponding exhaust valves 8 on the first pad 1 and the second pad 7 are not equal, which realizes the uniform distribution of gas throughout the pad, ensures that all parts of the pad can expand synchronously, and improves the overall stability of the air bed.

[0029] Specifically, the air inlet valve 9 is a one-way air inlet valve. The one-way air inlet valve only allows gas to enter the pad in one direction, preventing gas backflow and ensuring the smooth progress of the inflation process. This enables the air bed to be filled with gas quickly and stably during inflation, avoiding problems such as insufficient inflation or slow inflation caused by gas backflow, and improving inflation efficiency.

[0030] Specifically, both the air inlet valve 9 and the air outlet valve 8 are located on one side of the first pad 1 and the second pad 7, and are on the side in the width direction of the first pad 1 and the second pad 7. By placing the air inlet valve 9 and the air outlet valve 8 on the side of the pad, it is convenient for users to operate during inflation and deflation. At the same time, it avoids the discomfort that the valves might cause to users if they are located on the upper surface of the pad. This makes the inflation and deflation of the air bed convenient and improves the user comfort of the product.

[0031] Specifically, the first pad 1 is also provided with a first extension 5, which is located at both ends in the width direction of the first pad 1.

The provision of the first extension 5 increases the structural stability of the first pad 1. The limiting member 3 can limit the patient and prevent the patient from moving freely on the air bed. The traction member 4 facilitates the user to move or adjust the position of the air bed, realizing the safety and convenience of the air bed during use, improving the quality of patient care and the operational efficiency of the user.

[0032] Specifically, the first pad 1 also includes a first sac area 11 and a second sac area 12, the first sac area 11 and the second sac area 12 intersect each other, and a marking layer 13 is also provided on the second sac area 12.

[0033] Specifically, the limiting member 3 and the traction member 4 are located on the upper and lower sides of the first extension member 5, respectively.

[0034] Specifically, in the second embodiment, the limiting member 3 and the traction member 4 are both located on the side of the first extension member 5 opposite to the first pad body 1 used to support personnel.

[0035] Specifically, both the limiting component 3 and the traction component 4 are provided in two sets, with the two sets of traction components 4 located between the two sets of limiting components 3. The arrangement of the two sets of limiting components 3 and traction components 4 can provide a more stable limiting and traction effect, making the air bed safer and more reliable when carrying patients. The traction component 4 is located between the two sets of limiting components 3, which makes it easier for the user to maintain balance during traction. This achieves dual protection for the air bed in terms of limiting and traction, improving the overall performance and safety of the product.

[0036] Specifically, the limiting component 3 includes a male and female strap at both ends in the width direction of the first pad 1. The ends of the male and female straps are used to lock and limit the personnel carried on the first pad 1. The design of the male and female straps can be easily adjusted and locked according to the patient's body shape and needs, effectively preventing the patient from sliding or falling off the air bed, realizing reliable limiting of the patient, and improving the applicability and safety of the air bed in medical care and other scenarios.

[0037] Specifically, the first pad 1 is provided with second extensions 6 at both ends along its length. Both the first extension and the second extension are located on the first pad 1 near the end used to support personnel. The second extension 6 is provided with the same traction member 4. The second extension 6 further increases the structural stability of the first pad 1 and forms a more complete support structure in conjunction with the first extension 5. The traction member 4 on it facilitates the traction of the air bed from different directions, thereby optimizing the structure and traction of the air bed and improving the overall performance and flexibility of the product.

[0038] Specifically, the connecting component 2 includes a first connector 21 disposed on the second pad 7 and a second connector 22 disposed on the first pad 1. The second pad 7 is disposed on the first pad 1 via the connecting component 2. The design of the connecting component 2 enables the second pad 7 and the first pad 1 to be detachably connected, which facilitates the combination and adjustment of the air bed according to actual needs. This enables the multi-level combination and flexible use of the air bed, meeting the diverse needs of different scenarios and personnel for air bed height, comfort, and other aspects.

[0039] Specifically, the first connector 21 and the second connector 22 are zippers.
