Description
Technical Field
[0001] This invention relates to a transfer air mattress that can be quickly inflated and deflated, belonging to the field of mattress technology. Background Technology
[0002] Transport air cushions are widely used in hospitals, nursing homes, and home care settings. They can help medical staff transfer patients from beds, wheelchairs, stretchers, and other locations to operating tables, examination beds, and other locations. They are also suitable for transferring critically ill patients to other beds, turning them to their side, cleaning them, and other operations. They can also be used in outdoor emergency care and other fields.
[0003] For example, the pressure injury prevention mattress for use on a flatbed disclosed in patent application publication number CN109998795 (Second Slide) and publication date 20190712 includes an air mattress, an air pump, a control device, a solenoid valve, and a power supply device. It can meet the needs of different individuals for air mattresses and effectively prevent pressure injuries during the recovery period of patients after general anesthesia and during transportation.
[0004] In related technologies, the inflation and / or deflation rates of air mattresses are not high, making it difficult to meet the timeliness requirements of "1-3 minutes rapid response" in emergency situations, affecting the efficiency of patient transfer. In addition, air mattresses occupy a large area, making them difficult to store and move, thus limiting their portability and ease of use.
[0005] To overcome the above-mentioned shortcomings, this application provides a transport air cushion that can be quickly inflated and deflated, which can improve the inflation and deflation efficiency of the transport air cushion. Furthermore, the hinged component allows the transport air cushion to be bent and rolled up as a whole, which facilitates the storage and transportation of the transport air cushion, thereby improving portability and ease of use.

The third direction is perpendicular to the first direction and the second direction.
[0008] In some embodiments, the transfer air cushion further includes a limiting cylinder, a sliding rod, and a plurality of hinge plates. The limiting cylinder is disposed within the fixed frame, located below the inflation tube and extending along a first direction. A plurality of first sliding grooves are provided on the side near the inflation tube. The sliding rod is disposed in the inner cavity of the limiting cylinder and is slidably connected to the limiting cylinder. The plurality of hinge plates are disposed one-to-one with the plurality of first sliding grooves and are evenly distributed between the limiting cylinder and the inflation tube. One end of the hinge plate is hinged to the inflation tube, and the other end passes through the first sliding groove and is hinged to the sliding rod.
[0009] In some embodiments, the transport air cushion further includes a first connecting block and a second connecting block. Each side pad is provided with a first connecting block on both sides of one end near the fixed frame. One end of the first connecting block is hinged to the upper pad plate of the side pad, and the other end overlaps the upper part of the inflation tube, and a first elastic element is provided between the first connecting block and the inflation tube. Each side pad is provided with a second connecting block on both sides of one end near the fixed frame. One end of the second connecting block is hinged to the lower pad plate of the side pad, and the other end is fixedly connected to the fixed frame.
[0010] In some embodiments, a second groove is provided on the side of the air supply frame near the air inlet pipe. The second groove extends in a third direction, and an air outlet is opened in the second groove. The air outlet pipe is slidably connected to the second groove.
[0011] In some embodiments, the inflation tube is provided with multiple openings, and multiple air outlet tubes are respectively inserted into the multiple openings; one end of each air outlet tube located outside the inflation tube is slidably connected to the second sliding groove, and a limiting ring is provided around the periphery of the end located inside the inflation tube. Multiple second elastic members are provided between the side of the limiting ring near the air supply frame and the inner wall of the inflation tube.
[0012] In some embodiments, a first slider is provided on the side of the gas delivery frame near the main body, and a third sliding groove is provided on the side of the upper pad of the side pad near the gas delivery frame, and the third sliding groove is slidably connected to the first slider.
[0013] In some embodiments, among a plurality of sub-pads distributed along a first direction, hinge shafts disposed on both ends of the upper pad are sequentially connected to form two parallel hinge shafts, and hinge shafts disposed on both ends of the lower pad are sequentially connected to form two parallel hinge shafts.
[0014] In some embodiments, at least a portion of the sub-pad is further provided with a support assembly, which includes an electromagnet, a hinge seat, and a support block. The electromagnet is disposed in the lower pad, the hinge seat is disposed in the airbag and fixedly connected to the upper pad, and the support block is disposed in the airbag and hinged to the hinge seat. A magnetic block is disposed on the side opposite to the hinge seat.
[0015] In some embodiments, the transport air cushion further includes a side plate disposed on the side of the main body away from the fixing frame, and a pad strip disposed in a sub-pad near the side plate, wherein the upper pad plate and the lower pad plate are both hinged to the side plate.

Each first connecting rope is provided with a second connecting rope on both sides.
[0017] In this embodiment, the transport air cushion is in a deflated state, with the air bladder completely collapsed. This results in a smaller gap between the upper and lower pads and a thinner overall body. Medical personnel can fold the entire body using the fixed frame as the starting or ending point, reducing the space occupied by the transport air cushion and facilitating its storage and transport. This eliminates the need for multiple people to lift or carry it, improving its portability and ease of use. Furthermore, the chain-like connection allows the folded transport air cushion to be quickly unfolded and put into use, further enhancing its convenience.
[0018] In this embodiment, when the transport air cushion is inflated, it can provide flexible support for the patient as a whole. The design of the air bladder allows the height of the sub-cushion to adapt to changes in the curves and weight of the human body. The upper surface of the transport air bladder can conform to the human body, providing dynamic conformal support for the patient. This can improve the stability of the support for the patient's body and reduce the probability of secondary injury during transport. It is especially suitable for patients with fractures and spinal injuries, as it can reduce pain caused by changes in body position and reduce the probability of aggravation of the injury.
[0019] In this embodiment, the inflation tube, the deflation tube, and the air delivery frame allow for the simultaneous inflation and deflation of multiple pads, improving the inflation and deflation efficiency and ease of use of the transport air cushion, thereby increasing patient transport efficiency and convenience.

[0046] This invention provides a transport air cushion that can be rapidly inflated and deflated, such as... Figures 1 to 19 As shown, it can improve the inflation and deflation efficiency of the transport air cushion, and the hinged parts allow the transport air cushion to be bent and rolled up, which facilitates the storage and transportation of the transport air cushion, improving portability and ease of use.
[0047] This application provides a transport air cushion that can be quickly inflated and deflated, such as... Figures 1 to 3As shown, the transport air cushion includes a main body 1 and a fixing frame 2. The main body 1 includes a plurality of pad strips 11 evenly and spaced along a first direction X. Each pad strip 11 includes a plurality of sub-pads 110 evenly distributed along a second direction Y. Each sub-pad 110 includes an upper pad plate 101, an airbag 102, and a lower pad plate 103 arranged sequentially from top to bottom. In each pad strip 11, the upper pad plate 101 of adjacent sub-pads 110 is hinged end to end, the airbag 102 is connected end to end through a conduit, and the lower pad plate 103 is hinged end to end. The first direction X and the second direction Y are perpendicular. The fixing frame 2 is disposed on one side of the main body 1 and extends along the first direction X. The inner cavity is provided with a slidably connected inflation tube 21 and a plurality of air delivery frames 22. The inflation tube 21 is located at the air delivery frame 2. 2. On the side opposite to the main body 1, there are multiple air outlet pipes 211. The air supply frame 22 is correspondingly arranged with the pad strip 11 and the frame body has an air supply hole 221. The sub-pad 110 includes a side pad 12 connected to the fixed frame 2. The upper pad plate 101 of the side pad 12 is slidably connected to the air supply frame 22 and hinged to the inflation pipe 21. The lower pad plate 103 is hinged to the fixed frame 2. The airbag 102 and the air supply hole 221 are connected. The inflation pipe 21 is configured to move along the third direction Z on one side of the air supply frame 22 so that the air outlet pipe 211 is aligned with the air supply hole 221 to inflate the airbag 102, or so that the air outlet pipe 211 is misaligned with the air supply hole 221 to deflate the airbag 102. The third direction Z is perpendicular to the first direction X and the second direction Y.
[0048] In this embodiment, the pad strip 11 is composed of multiple sub-pads 110 arranged in an array along the second direction Y. Among the multiple sub-pads 110 within a pad strip 11, the upper pad plate 101 is hinged end to end, and the lower pad plate 103 is hinged end to end, so that the upper and lower surfaces of the pad strip 11 form a chain-like structure similar to a mechanical watch chain. The air bladder 102 in the middle is a flexible structure and is connected through a flexible conduit, so that the pad strip 11 as a whole is a flexible structure that can be bent and rolled along the second direction Y. The main body 1 is composed of multiple pads 11 arranged in an array along the first direction X, so that the main body 1 as a whole can also be bent and rolled along the second direction Y.
[0049] In this embodiment, the transport air cushion is in a deflated state, and when the airbag 102 is in a deflated state, the distance between the upper pad 101 and the lower pad 103 is small, and the overall thickness of the main body 1 is small. The fixing frame 2 is located at the beginning or end of the pad strip 11, allowing medical personnel to roll and fold the main body 1 using the fixing frame 2 as the starting or ending point. This reduces the space occupied by the transport air cushion, making it easier to store and transport without requiring multiple people to lift it, thus improving its portability and ease of use. Furthermore, the chain-like connection method allows the folded transport air cushion to be quickly unfolded and put into use, further improving its ease of use.
[0050] In this embodiment, the upper surface of the airbag 102 is fixedly connected to the upper pad 101, and the lower surface is fixedly connected to the lower pad 103. The side of the airbag 102 communicates with adjacent airbags 102 via conduits. Both ends of the air delivery frame 22 are fixedly connected to the fixing frame 2. The area and number of the upper pad 101, airbag 102, and lower pad 103 can be set according to actual needs. For example, the smaller the area and the greater the number of airbags, the more refined the composition of the main body 1, and the better the bending and winding effect. The height of the airbag 102 can also be set according to actual needs; this application does not limit this.
[0051] In this embodiment, one end of the inflation tube 21 is connected to an external air pump 9 and has a control button. Multiple air outlet tubes 211 are used to divert air from the inflation tube 21. The number and position of the air outlet tubes 211, the air delivery frame 22, and the pad strip 11 are arranged in a one-to-one correspondence. The gas diverted by the air outlet tube 211 is transmitted to the air delivery hole 221 of the matching air delivery frame 22, and inflates or deflates all the airbags 102 in one of the matching pad strips 11 through the air delivery hole 221. The third direction Z is perpendicular to the ground.
[0052] In this embodiment, when the transport air cushion is put into use, the air cushion, which is in a deflated state and has a small overall thickness, can be laid on one side at an angle under the patient. Then, the inflation tube 21 is driven to move upward, causing the air outlet tube 211 to move upward and align with the air inlet 221. The air pump 9 is then turned on, allowing gas to flow simultaneously through the multiple air outlet tubes 211 of the inflation tube 21 to the multiple air inlets 221, thereby simultaneously inflating the multiple pads 11, making the airbag 102 full. The upper pad 101 moves upward under the support provided by the airbag 102, causing the transport airbag 102 to extend as a whole and increase in thickness. Once the thickness of the transport air cushion meets the requirements, the air pump 9 is turned off.
[0053] In this embodiment, when the transport air cushion is inflated, it can provide flexible support for the patient as a whole. The design of the airbag 102 allows the height of the sub-cushion 110 to adapt to changes in the curves and weight of the human body. The upper surface of the transport airbag 102 can conform to the human body, providing dynamic conformal support for the patient. This can improve the stability of the support for the patient's body and reduce the probability of secondary injury during transport. It is especially suitable for patients with fractures and spinal injuries, as it can reduce pain caused by changes in body position and reduce the probability of aggravation of the injury.
[0054] In this embodiment, when the transport mattress needs to be folded up after transport is completed, the inflation tube 21 is driven downwards, causing the air outlet tube 211 to move downwards and disengage from the air inlet 221. Multiple pads 11 can be depressurized simultaneously through the air inlet 221. The upper pad 101 moves downwards following the depressurization of the airbag 102, causing the transport airbag 102 to contract as a whole, reducing its thickness and allowing it to be rolled up and folded for easy storage and transport. Through the configuration of the inflation tube 21, air outlet tube 211, and air inlet frame 22, multiple pads 11 can be inflated and deflated simultaneously, improving the inflation and deflation efficiency and ease of use of the transport airbag, thereby increasing patient transport efficiency and convenience.
[0055] In this embodiment, the fixing frame 2 is provided with a sliding groove extending in the third direction Z. The two ends of the inflation tube 21 are engaged and slidably connected to the fixing frame 2 through the sliding groove, which can improve the movement stability of the inflation tube 21 and improve the working stability of the transfer air cushion.
[0056] In this embodiment, the transport air cushion measures 1.8m to 2.0m in length, 0.6m to 0.8m in width, and 0.04m to 0.08m in height, comprising 10 to 16 pads 11, each pad including 6 to 8 sub-pads 110. In one example, the transport air cushion consists of 16 pads 11, each pad 11 being 0.1m in length and 0.6m in width. In this case, a miniature brushless DC air pump can be used, with dimensions of approximately 120mm × 80mm × 60mm (length, width, height). The operating parameters are: rated voltage 12V, rated power 30 to 40W, exhaust flow rate 8 to 12L / min, and operating pressure 50 to 80kPa, which can complete the inflation operation within 1 to 3 minutes.
[0057] In some embodiments, such as Figure 9 , Figure 11 and Figure 14 As shown, the transfer air cushion also includes a limiting cylinder 3, a sliding rod 32, and multiple hinge plates 33. The limiting cylinder 3 is disposed inside the fixing frame 2, located below the inflation tube 21 and extending along the first direction X. Multiple first sliding grooves 31 are provided on the side near the inflation tube 21. The first sliding grooves 31 are used to provide moving space for the hinge plates 33. The sliding rod 32 is disposed in the inner cavity of the limiting cylinder 3 and is slidably connected to the limiting cylinder 3. Multiple hinge plates 33 are provided one-to-one with multiple first sliding grooves 31 and are evenly distributed between the limiting cylinder 3 and the inflation tube 21. One end of the hinge plate 33 is hinged to the inflation tube 21, and the other end passes through the first sliding groove 31 and is hinged to the sliding rod 32.
[0058] In this embodiment, the limiting cylinder 3 is fixedly connected to the lower part of the fixing frame 2, and the first sliding groove 31 extends along the first direction X. Multiple first hinge seats 42 are provided below the inflation pipe 21, and multiple second hinge seats 42 are provided above the sliding rod 32. The positions of the first hinge seats 42, the second hinge seats 42, the hinge plate 33, and the first sliding groove 31 are all correspondingly arranged. Both ends of the hinge plate 33 are hinged to the first hinge seats 42 and the second hinge seats 42 respectively via hinge shafts, and the hinge shafts extend along the second direction Y. A handle is provided on one side of the sliding rod 32 to facilitate manual pulling of the sliding rod 32.
[0059] In this embodiment, when deflating the transport air cushion, medical staff manually pull the handle, causing the sliding rod 32 to extend at least partially out of the limiting cylinder 3. The sliding rod 32 moves the hinge plate 33, changing it from a vertical to an inclined state, reducing its height. The hinge plate 33 then moves the inflation tube 21 downward, exposing multiple air outlets 221 to depressurize the transport air cushion. When inflating the transport air cushion, medical staff manually pull the handle, causing the sliding rod 32 to retract into the limiting cylinder 3. The sliding rod 32 moves the hinge plate 33, changing it from an inclined to a vertical state, increasing its height. The hinge plate 33 then moves the inflation tube 21 upward, aligning the air outlet tube 211 with the air outlets 221 to inflate the transport air cushion.
[0060] In this embodiment, the limiting cylinder 3, the sliding rod 32, and multiple hinge plates 33 can form an inflation / deflation control assembly. The sliding rod 32 can be used to push, pull, and slide to control the up and down movement of the inflation tube 21 in a simple, convenient, and stable manner, thereby achieving the connection of the gas supply pipeline. It has the advantages of simple structure and convenient operation.
[0061] In some embodiments, such as Figure 18 As shown, the fixed frame 2 is also provided with a locking assembly 34. The locking assembly 34 is located on the side of the sliding rod 32 away from the handle. It includes a locking plate 341, a locking rod 343 and a third elastic element 344. The locking plate 341 is fixedly connected to the sliding rod 32. A locking groove 342 is provided on the locking plate 341. The third elastic element 344 is provided between the locking plate 341 and the fixed frame 2. One end of the locking rod 343 is hinged to the inner wall of the fixed frame 2, and the other end is locked and slidably connected to the locking groove 342 through a locking block.
[0062] In this embodiment, the slot 342 is a pentagonal irregular slot with a symmetrical structure. The side of the slot 342 closest to the sliding rod 32 has a concave V-shaped bend, creating two spaced-apart V-shaped areas. The sharp corners of these V-shaped areas are the engagement points between the locking rod 343 and the slot 342. When the locking plate 341 and the locking rod 343 are not subjected to external force, the locking rod 343 can be stably engaged at the engagement point. The third elastic element 344 can be a helical tension spring, made of materials including spring steel and stainless steel.
[0063] In this embodiment, when the sliding rod 32 is pulled out of the limiting cylinder 3, the sliding rod 32 drives the locking plate 341 to move, causing the locking rod 343 to engage with the locking point on the side of the locking plate 341 near the third elastic member 344. This limits the position of the sliding rod 32 after it is pulled out, allowing the sliding rod 32 to maintain its current position, thereby stably deflating the transport air cushion. At this time, the third elastic member 344 is stretched. When the sliding rod 32 is pushed back into the limiting cylinder 3, the sliding rod 32 drives the locking plate 341 to move, causing the locking rod 343 to engage with the locking point on the side of the locking plate 341 near the sliding rod 32. This limits the position of the sliding rod 32 after it is pushed back, allowing the sliding rod 32 to maintain its current position, thereby stably inflating the transport air cushion. At this time, the third elastic member 344 can provide elastic force to assist the sliding rod 32 in pushing back, reducing the difficulty of pushing. The deflating and inflation stability of the transport air cushion can be improved by the locking assembly 34, thus improving the application effect of the transport air cushion.
[0064] In some embodiments, such as Figure 12 As shown, the transport air cushion also includes a first connecting block 23 and a second connecting block 24. Each side pad 12 has a first connecting block 23 on both sides near the fixed frame 2. One end of the first connecting block 23 is hinged to the upper pad plate 101 of the side pad 12, and the other end overlaps the inflation tube 21. A first elastic element is provided between the first connecting block 23 and the inflation tube 21, with both ends of the first elastic element fixedly connected to the first connecting block 23 and the tube wall of the inflation tube 21, respectively. Each side pad 12 also has a second connecting block 24 on both sides near the fixed frame 2. One end of the second connecting block 24 is hinged to the lower pad plate 103 of the side pad 12, and the other end is fixedly connected to the fixed frame 2. The first elastic element includes a helical tension spring, made of spring steel and stainless steel.
[0065] In this embodiment, when deflation begins, the airbag 102 is inflated, and the gap between the upper pad 101 and the lower pad 103 is relatively large. When the inflation tube 21 moves downward, the third elastic element 344 is stretched, creating a gap between the inflation tube 21 and the upper pad 101, thereby disconnecting it from the air outlet 221. This facilitates deflation without affecting the hinge of the upper pad 101, improving the working stability of the inflation tube 21 and the stability of the deflation operation. Furthermore, the weight of the upper pad 101 itself can assist in deflation of the airbag 102, further improving deflation efficiency. After deflation is complete, the upper pad 101 moves downward, and the third elastic element 344 returns to its original state.
[0066] In this embodiment of the application, hinge holes are provided on the first connecting block 23, the second connecting block 24, the upper pad 101 and the lower pad 103. The transfer air cushion also includes a hinge shaft. The hinge shaft passes through the hinge holes of the first connecting block 23 and the upper pad 101 to achieve the hinge between the two. The hinge shaft passes through the hinge holes on the second connecting block 24 and the lower pad 103 to achieve the hinge between the two.
[0067] In some embodiments, such as Figure 12 and Figure 16 As shown, a second groove 222 is provided on the side of the air supply frame 22 near the inflation tube 21. The second groove 222 extends in the third direction Z, and the air supply hole 221 is opened in the second groove 222. The air outlet tube 211 is slidably connected to the second groove 222. The second groove 222 and the air outlet tube 211 can limit and guide the vertical movement of the inflation tube 21, improve the movement stability of the inflation tube 21, and thus improve the working stability of the transfer air cushion.
[0068] In this embodiment, the end of the air outlet pipe 211 away from the inflation pipe 21 is chamfered to facilitate connection or disconnection between the air outlet pipe 211 and the air inlet 221. A rubber sealing ring or gasket is provided at the end of the air inlet 221 near the inflation pipe 21 to improve the stability of airflow transmission between the air outlet pipe 211 and the air inlet 221 and prevent air leakage.
[0069] In some embodiments, such as Figure 9 As shown, the inflation tube 21 has multiple openings, and multiple air outlet tubes 211 are respectively inserted into the multiple openings and slidably connected to the openings. A rubber or plastic sealing ring is provided between the inflation tube 21 and the opening to improve the connection sealing and prevent air leakage. The end of each air outlet tube 211 located outside the inflation tube 21 is slidably connected to the second sliding groove 222, and the periphery of the end located inside the inflation tube 21 is provided with a limiting ring 212. Multiple second elastic elements 213 are provided between the side of the limiting ring 212 near the air supply frame 22 and the inner wall of the inflation tube 21. The second elastic elements 213 include spiral tension springs or elastic ropes.
[0070] In this embodiment, when the outlet pipe 211 and the air inlet 221 are disengaged, the outlet pipe 211 is subjected to the compressive force provided by the air supply frame 22, causing a portion of the pipe section to retract into the inflation pipe 21. This increases the distance between the limiting ring 212 and the inner wall of the inflation pipe 21, and the second elastic element 213 is in a stretched state. When the outlet pipe 211 and the air inlet 221 are connected, the compressive force provided by the air supply frame 22 is removed, the second elastic element 213 contracts, and through its own elastic force, it drives the outlet pipe 211 to move and tightly abut against the air inlet 221, thus achieving the connection of the air supply pipeline.
[0071] In some embodiments, such as Figure 9 and Figure 17As shown, a first slider 223 is provided on the side of the air supply frame 22 near the main body 1, and a third sliding groove 121 is provided on the side of the upper pad 101 of the side pad 12 near the air supply frame 22. The third sliding groove 121 is slidably connected to the first slider 223. The third sliding groove 121 and the first slider 223 can limit and guide the up and down movement of the upper pad 101 of the side pad 12, improve the movement stability of the upper pad 101, and further improve the inflation and deflation stability of the transfer air cushion.
[0072] In this embodiment, the first slider 223 can be positioned around the air inlet 221, or a channel communicating with the air inlet 221 can be provided inside the first slider 223, to ensure the stability of the communication between the air inlet 221 and the airbag 102, reduce the probability of wear at the connection between the airbag 102 and the air inlet 221 caused by the up-and-down movement of the upper pad 101, and improve the service life of the transport airbag.
[0073] In some embodiments, such as Figure 13 As shown, among the multiple sub-pads 110 distributed along the first direction X, the hinge shafts located on both ends of the upper pad 101 are sequentially connected to form two parallel hinged long shafts 13, and the hinge shafts located on both ends of the lower pad 103 are sequentially connected to form two parallel hinged long shafts 13. Limiting blocks are provided at both ends of the hinged long shafts 13 to engage with both sides of the upper pad 101 and the lower pad 103, preventing the hinged long shafts 13 from disengaging and improving hinge stability.
[0074] In this embodiment, the transfer air cushion includes a parallel upper hinge layer and a lower hinge layer. Each hinge layer includes a plurality of parallel and spaced-apart hinge shafts 13 extending along a first direction X. The hinge shafts 13 of the upper hinge layer connect a plurality of upper pads 101 distributed along the first direction X, and hinge adjacent upper pads 101 distributed along the second direction Y end to end, and also hinge the upper pads 101 to the first connecting block 23. The hinge shafts 13 of the lower hinge layer connect a plurality of lower pads 103 distributed along the first direction X, and hinge adjacent lower pads 103 distributed along the second direction Y end to end, and also hinge the lower pads 103 to the second connecting block 24.
[0075] In some embodiments, such as Figure 5 , Figure 6 , Figure 8 and Figure 10As shown, at least some of the sub-pads 110 are also provided with a support assembly 4. The support assembly 4 includes an electromagnet 41, a hinge seat 42, and a support block 43. The electromagnet 41 is disposed in the lower pad 103, the hinge seat 42 is disposed in the airbag 102 and fixedly connected to the upper pad 101; the support block 43 is disposed in the airbag 102 and hinged to the hinge seat 42, and a magnetic block 44 is disposed on the side opposite to the hinge seat 42. The hinge axis between the support block 43 and the hinge seat 42 extends along the first direction X. The support assembly 4 can be disposed in all sub-pads 110 or in some sub-pads 110, depending on actual needs, and this application does not limit this. Multiple electromagnets 41 are electrically connected by wires, and the lower pad 103 is provided with an internal channel to accommodate the wires. The magnetic block 44 includes a magnet.
[0076] In this embodiment, after the transport air cushion is fully inflated, there is sufficient space between the upper pad 101 and the lower pad 103. The support block 43 falls freely under gravity and is vertically suspended between the hinge seat 42 and the electromagnet 41. At this time, the connecting wire of the electromagnet 41 is connected to an external power source. When the electromagnet 41 is energized, it generates magnetism and attracts the magnetic component below the support block 43. This maintains the vertical position of the support block 43 for a long time while the electromagnet 41 is energized, thereby providing support for the upper pad 101, giving the transport air cushion a certain rigidity, providing effective support for the patient, and improving transport comfort and stability.
[0077] In this embodiment, before deflating the transport air cushion, the connection between the power supply and the connecting wire of the electromagnet 41 is disconnected. This allows the support block 43 to rotate and fold relative to the hinge seat 42 during deflation, preventing obstruction to the movement of the upper pad 101 and the contraction of the airbag 102. After rotation and folding, the support block 43 is in close contact with the upper pad 101. The thickness of the support block 43 is less than or equal to the thickness of the hinge seat 42, avoiding increasing the thickness of the transport air cushion during storage. When the support block 43 is in a vertical state, there is a gap between it and the lower pad 103 to provide space for the rotation of the support block 43 during deflation. Along the first direction X, the left and right ends of the magnetic component are provided with chamfers or rounded corners as smooth transition sections to facilitate the rotation and folding of the support block 43.
[0078] In some embodiments, such as Figure 1 and Figure 2 As shown, the transfer air cushion also includes a side plate 5, which is disposed on the side of the main body 1 away from the fixing frame 2. The pad strip 11 is disposed in the sub-pad 110 near the side plate 5, and the upper pad 101 and the lower pad 103 are both hinged to the side plate 5. The side plate 5 extends along the first direction X and is disposed parallel to the fixing frame 2 for fixing the other side of the main body 1.
[0079] In the embodiments of this application, such as Figure 19As shown, a third connecting block 51 is provided between the upper pad 101 and the side plate 5. One end of the third connecting block 51 is hinged to the upper pad 101, and the other end is slidably connected to a groove on the inner wall of the side plate 5, so that the upper pad 101 on this side moves synchronously with the change of the airbag 102. A fourth connecting block 52 is provided between the lower pad 103 and the side plate 5. One end of the fourth connecting block 52 is hinged to the lower pad 103, and the other end is fixedly connected to the side plate 5, realizing the hinge connection between the side plate 5 and the lower pad 103.
[0080] In some embodiments, such as Figure 1 and Figure 2 As shown, the transport air cushion also includes multiple first connecting ropes 61 and multiple second connecting ropes 62. The multiple first connecting ropes 61 are evenly and spaced above the main body 1, with one end connected to the fixing frame 2 and the other end connected to the side plate 5. Each first connecting rope 61 has a second connecting rope 62 on both sides. The first connecting ropes 61 can be straps used to fix the transported patient and the main body 1, reducing the probability of the patient shaking significantly during transport and improving transport stability. The second connecting ropes 62 are used to connect and fix the transport air cushion and the hospital bed, improving the stability of the transport air cushion.
[0081] In some embodiments, the second connecting rope 62 can also be connected to the fixing frame 2 or the side plate 5. The lengths of the first connecting rope 61 and the second connecting rope 62 can be adjusted using structures such as Velcro, snaps, or clips, increasing the application range of the transport air cushion. Along the second direction Y, connecting fabrics are respectively provided on both sides of the main body 1. The upper and lower ends of each connecting fabric are fixedly connected to the upper pad 101 and the lower pad 103, respectively, wrapping around both sides of the main body 1. The connecting fabrics can protect both sides of the main body 1 without affecting the folding function of the transport air cushion, preventing the probability of patients accidentally touching the airbag 102 during inflation and deflation, leading to problems such as finger compression, and improving the application safety of the transport air cushion.
[0082] In the embodiments of this application, such as Figure 1 and Figure 2 As shown, handles 7 are provided on both the fixing frame 2 and the side plate 5 to facilitate medical staff in lifting and moving the transport air cushion. A soft pad 8 is provided on the upper surface of the main body 1 to improve the comfort of using the transport air cushion. The soft pad 8 can be a single piece or composed of multiple soft pad blocks evenly distributed on the upper pad plate 101. The soft pad 8 includes a seamless sealed PU (Polyurethane) film coated with a silver ion antibacterial coating, offering advantages such as being non-porous, easy to clean, resistant to high-pressure water guns and chemical disinfection, meeting hygiene standards, and reducing the risk of cross-infection.
[0083] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0084] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
