Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a mattress for positioning hemiplegic patients and facilitating effortless turning over. Background Technology

[0002] Hemiplegic patients need to maintain a good limb posture while lying in bed. This good posture (also known as the antispastic position) can stabilize the joints after hemiplegia, effectively prevent typical spastic patterns of the upper limb flexors and lower limb extensors, and is also one of the methods to prevent the development of pathological movement patterns later. Therefore, when providing good posture support, medical staff need to use multiple pillows of different sizes and shapes to achieve good posture for different parts such as the shoulders, hips, and legs. The clinical practice is difficult, and the number of operations is very large every day. It is necessary to adjust the pillow position once every two hours or so when turning the patient over. The operations of turning the patient over and adjusting the pillow position result in a heavy physical workload for medical staff.

[0003] Some existing medical beds have air assist devices directly fixed to them to reduce the biomechanical load on the patient's limbs during turning. However, the entire medical bed is heavy, making it inconvenient for users to carry and use. For example, if the patient wants to continue using the bed at home after hospital use, the entire bed needs to be moved. Moreover, most hospitals do not purchase this type of specialized bed. In particular, since the air assist devices for turning are fixed to the medical bed, it is not suitable for scenarios where airbags are used alone, such as on a sofa, wheelchair, or floor (e.g., during rehabilitation training). The air assist devices on the bed cannot meet the needs for turning, decompression, or support in these environments, leading to limitations in its use.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a mattress for positioning hemiplegic patients in a good posture and for effortless turning over, so as to solve the problems of poor portability and limited use of medical beds with air-assisted devices in the prior art.

[0006] The technical solution of this application is as follows:

[0007] A mattress for positioning hemiplegic patients in a good posture and for effortless turning over, comprising: a flexible mat, the flexible mat being laid on a bed;

[0008] The posture adjustment airbag assembly is set on a flexible pad and expands by inflation to support different parts of the patient's body.

[0009] The air pump assembly is connected to the posture adjustment airbag group through pipelines and controls the inflation and deflation of each airbag in the posture adjustment airbag group individually.

[0010] The turning airbag is detachably mounted on a flexible mat to allow the patient to turn to their side by inflation. The turning airbag is detachably connected to the air pump assembly via tubing.

[0011] Optionally, the flexible pad is provided with a connector, and the turning airbag is detachably connected to the flexible pad through the connector;

[0012] The connectors include Velcro.

[0013] Optionally, the turning airbag includes a first airbag, which is positioned on one side of the wide midline of the flexible pad;

[0014] The first airbag is connected to the first turning tube, and the end of the first turning tube is provided with an air pipe connector. The first turning tube can be plugged into and detached from the air pump assembly through the air pipe connector.

[0015] Optionally, the turning airbag also includes a connecting edge, which is located on one side of the width direction of the first airbag and is detachably connected to the connector.

[0016] Optionally, the turning airbag also includes a second airbag, which is disposed on both sides of the connecting edge, along with the first airbag.

[0017] The second airbag is connected to a second turning tube. Both the second turning tube and the first turning tube are connected to the air pump assembly via air pipe connectors, and the first turning tube and the second turning tube are air-intaked separately.

[0018] Optionally, the flexible pad has through holes for the tubing of the turning airbag to pass through;

[0019] The flexible pad has a concave back to form a limiting groove, which is used to accommodate the tubing of the turning airbag.

[0020] Optionally, the multiple airbags in the posture adjustment airbag group include: one head pad airbag, two shoulder pad airbags, two hip pad airbags, and two lower limb pad airbags;

[0021] The two shoulder pads, two hip pads, and two lower limb pads are arranged symmetrically on both sides.

[0022] The multiple airbags in the posture adjustment airbag assembly are connected to the air pump assembly through posture adjustment pipelines and are individually inflated and deflated.

[0023] Optionally, the air pump assembly includes an air pump body and a control unit, the control unit is connected to the air pump body, multiple posture adjustment lines are connected to the control unit, and the turning airbag is connected to the control unit via a pluggable line;

[0024] The control unit contains multiple pneumatic control sections, which are connected to attitude adjustment lines and pluggable lines, respectively.

[0025] Optionally, the air circuit control unit includes: a one-way valve, the air inlet of which is connected to the air pump body, and the air outlet of which is connected to the attitude adjustment pipeline or a pluggable pipeline.

[0026] The solenoid valve is connected to the vent pipe, and the other end of the vent pipe is connected to the outlet of the check valve.

[0027] When the solenoid valve is closed, the check valve is used to deliver the air generated by the air pump body in one direction to the attitude adjustment pipeline or the pluggable pipeline.

[0028] With the solenoid valve in the open position, the solenoid valve is used to vent the attitude adjustment pipeline or pluggable pipeline.

[0029] Optionally, the air pump assembly also includes a hook, through which the air pump assembly is attached to the bedside.

[0030] The beneficial effects of the mattress provided in this application for positioning and effortless turning of hemiplegic patients are at least as follows: By placing both the positioning airbag group and the turning airbag on a flexible mat, the mattress can be directly laid on the bed during use. The air pump assembly allows for individual inflation and deflation control of each airbag in the positioning airbag group and the turning airbag. This allows for individual inflation and deflation of the airbags in the positioning airbag group, enabling positioning in the affected side, unaffected side, and supine positions. The expansion and contraction of the turning airbag assists the patient in turning and lateral positioning, reducing the burden on medical staff and eliminating the need for pillows. When transferring from the hospital to home use, the mattress can be simply rolled up, improving portability. Furthermore, when the turning airbag needs to be used independently, it can be detached from the flexible mat and detachably connected to the air pump assembly via tubing. This allows it to be moved to sofas, wheelchairs, or the floor, meeting the needs for turning over, decompression, or support in different environments. It significantly improves care efficiency and comfort, making it particularly suitable for home-based elderly care, post-operative rehabilitation, and long-term care scenarios. Its lightweight design facilitates operation by the elderly or caregivers, reducing physical burden. This solution uses a flexible pad and an air pump component to easily achieve proper posture adjustment and turning over. It can be folded down into a small volume for easy portability and widespread adoption. This product greatly helps hemiplegic patients achieve proper posture and effortless turning over, truly fulfilling the services patients need. Attached Figure Description

[0037] This application provides a mattress for positioning hemiplegic patients in a favorable posture and facilitating effortless turning. To make the purpose, technical solution, and effects of this application clearer and more explicit, the following detailed description is provided with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit the scope of this application.

[0040] like Figure 1 , Figure 2 As shown, this application also proposes a mattress for positioning and effortless turning of hemiplegic patients, mainly comprising: a flexible mat 100, a posture-adjusting airbag assembly 200, an air pump assembly 400, and a turning airbag 300. The flexible mat 100 can be a sponge mat covered with fabric, or a cloth mat, etc. It can be laid on the bed, folded, or rolled up for portability. For ease of structural description, the flexible mat 100 can be rectangular to fit the bed, with the direction of the long side as the length direction (front-to-back direction) and the direction of the wide side as the width direction (left-to-right direction). Other structures in this embodiment are described using this direction as the standard. The posture-adjusting airbag assembly 200 is placed on the flexible mat 100 and expands by inflation to support different parts of the patient. The air pump assembly 400 is connected to the posture-adjusting airbag assembly 200 through tubing and controls the individual inflation and deflation of each airbag in the posture-adjusting airbag assembly 200. In the specific structure, the tubing of the air pump assembly 400 and each airbag in the posture adjustment airbag group 200 can be fixed, with the tubing passing through the interior of the flexible pad 100. In this case, the air pump assembly 400 is directly connected to the flexible pad 100 via the tubing and is not detachable, making installation relatively simple during use. Alternatively, the tubing of the air pump assembly 400 and each airbag in the posture adjustment airbag group 200 can be detachable. This requires alignment and installation during use, making the installation process more complicated, but it improves portability.

[0041] In this embodiment, the bottoms of multiple airbags in the posture adjustment airbag assembly 200 can be adhesively fixed to the inner surface of the flexible pad 100. The outer layer of the flexible pad 100 covers the surface of the airbags, and the outer layer can be relatively large so as not to hinder the expansion of the airbags. For example, the airbags can be adhesively fixed to the surface of the sponge pad, and the fabric can cover the surface of the airbags. Alternatively, the airbags can be directly fixed to the outer surface of the flexible pad 100, which can also solve the technical problem.

[0042] like Figure 1 , Figure 2 As shown, the posture adjustment airbag assembly 200 of this embodiment includes multiple airbags: one head cushion 210, two shoulder cushions 220, two hip cushions 230, and two lower limb cushions 240. The head cushion 210 can be located at the front end of the flexible pad 100, the two shoulder cushions 220 are located behind the head cushion 210, the two hip cushions 230 are located outside the shoulder cushions 220, and the lower limb cushions 240 are located behind the hip cushions 230. The two shoulder cushions 220, the two hip cushions 230, and the two lower limb cushions 240 are all arranged symmetrically from left to right. The tubing connected to the multiple airbags of the posture adjustment airbag assembly 200 is a posture adjustment tubing 250. The multiple airbags of the posture adjustment airbag assembly 200 are respectively connected to the air pump assembly 400 through the posture adjustment tubing 250 and are individually inflated and deflated. The head pad 210, one or two shoulder pads 220, one or two hip pads 230, and one or two lower limb pads 240 can be inflated to form different support shapes to support different parts of the patient, keep the patient in different good positions, and improve comfort.

[0043] In this embodiment, the mattress incorporates both the postural adjustment airbag assembly 200 and the turning airbag 300 on the flexible pad 100. During use, the mattress can be directly laid on the bed. The air pump assembly 400 individually controls the inflation and deflation of each airbag in the postural adjustment airbag assembly 200 and the turning airbag 300. This allows for individual inflation and deflation of the airbags in the postural adjustment airbag assembly 200, enabling patients to assume the affected side, unaffected side, and supine positions. The expansion and contraction of the turning airbag 300 assists patients in turning over and assuming a side-lying position, reducing the burden on medical staff and eliminating the need for pillows. When transitioning from hospital to home use, the mattress can be easily rolled up, improving portability.

[0044] like Figure 2 As shown, the turning airbag 300 in this embodiment is detachably mounted on the flexible pad 100 to allow the patient to turn to their side by inflation. The turning airbag 300 is detachably connected to the air pump assembly 400 via tubing. Because the turning airbag 300 is detachably mounted on the flexible pad 100, it can be removed from the flexible pad 100 and detachably connected to the air pump assembly 400 when needed for individual use. This allows it to be moved to a sofa, wheelchair, or floor to meet the needs of turning, decompression, or support in different environments. This significantly improves nursing efficiency and comfort, making it particularly suitable for home-based elderly care, postoperative rehabilitation, and long-term care scenarios. The lightweight design facilitates operation by the elderly or caregivers, reducing physical burden.

[0045] like Figure 1 , Figure 2 As shown, in this embodiment, a connector 110 is provided on the flexible pad 100, and the turning airbag 300 is detachably connected to the flexible pad 100 via the connector 110. The connector 110 includes Velcro 111, the loop side of which can be disposed on the surface of the flexible pad 100, and the hook side of which can be fixed to the turning airbag 300. In this way, the turning airbag 300 can be stably connected to the flexible pad 100 via the Velcro 111, and this also facilitates disassembly. It is easy to imagine that the connector can also be other structures, such as a zipper.

[0046] Since the turning airbag 300 is detachable, it can be a single airbag, positioned on the right side when turning to the left and on the left side after disassembly when turning to the right. Specifically, the turning airbag 300 in this embodiment includes a first airbag 310, positioned on one side of the wide center line of the flexible pad 100. The first airbag 310 is connected to a first turning tube 311, with an air pipe connector 312 at its end. The first turning tube 311 is pluggably connected to the air pump assembly 400 via the air pipe connector 312. The connection between the first turning tube 311 and the air pump assembly 400 allows for the inflation and deflation of the first airbag 310.

[0047] like Figure 1 , Figure 2 As shown, the turning airbag 300 in this embodiment further includes a connecting edge 320, which is disposed on one side of the width direction of the first airbag 310 and is detachably connected to the connector 110. The first airbag 310 has a rectangular structure, and the connecting edge 320 can be made of a strip of cloth, with the side of the cloth strip fixedly connected to the long side of the rectangle. The hook side of the Velcro 111 is disposed on the connecting edge 320. In use, by inflating the first airbag 310, the first airbag 310 can be expanded as a whole. Due to the traction of the connecting edge 320, the side of the first airbag 310 facing the width midline will be connected to the flexible pad 100, and the side of the first airbag 310 away from the width midline will be raised, thereby forming a pushing force that makes the patient turn to the other side, making it easier for the patient to turn over to the other side.

[0048] like Figure 3 , Figure 4As shown, in another structure, if disassembling the left and right side airbags 300 is cumbersome, the airbags 300 can be configured as two symmetrical airbags. When turning to the left, the right airbag inflates; when turning to the right, the left airbag inflates. Specifically, in addition to the first airbag 310, the airbag 300 also includes a second airbag 330. The second airbag 330 and the first airbag 310 are respectively located on both sides of the connecting edge 320. The second airbag 330 is connected to a second turning pipe 331. Both the second turning pipe 331 and the first turning pipe 311 are connected to the air pump assembly 400 via air pipe connectors 312, and each pipe has its own air intake. For example, when in use, the first airbag 310 is located on the left side and the second airbag 330 is located on the right side. When the patient turns to the right, the first airbag 310 is inflated while the second airbag 330 is not inflated. When the patient turns to the left, the second airbag 330 is inflated while the first airbag 310 is not inflated, which can help the patient turn over accordingly.

[0049] like Figure 3 , Figure 4 As shown, furthermore, to better mount the turning airbag 300 on the flexible pad 100, the flexible pad 100 in this embodiment has a through hole 120 for the tubing of the turning airbag 300 (first turning tubing 311 and / or second turning tubing 331) to pass through; a limiting groove 130 is formed inwardly on the back of the flexible pad 100, which is used to accommodate the tubing of the turning airbag 300. By limiting and constraining the first turning tubing 311 and / or the second turning tubing 331 of the turning airbag 300, the airway will not become messy.

[0050] like Figure 1 , Figure 3 , Figure 5 As shown, further, the air pump assembly 400 of this embodiment includes an air pump body 410 and a control component 420. The control component 420 can be a control box. The control component 420 is connected to the air pump body 410, and multiple posture adjustment lines 250 are connected to the control component 420. The turning airbag 300 is connected to the control component 420 via a pluggable line. The control component 420 contains multiple air path control units 430, which are respectively connected to the posture adjustment lines 250 and the pluggable lines. The multiple air path control units 430 are control switches, which allows for individual control of the inflation or deflation of the airbags in the posture adjustment airbag assembly 200 and the turning airbag 300, thereby achieving individual control functionality.

[0051] like Figure 1 , Figure 5As shown, further, when the air path control unit 430 controls the airbags in the posture adjustment airbag assembly 200, the air path control unit 430 in this embodiment specifically includes: a one-way valve 434 and a solenoid valve 438. The air inlet end of the one-way valve 434 is connected to the air pump body 410, and the air outlet end of the one-way valve 434 is connected to the posture adjustment pipeline 250. The solenoid valve 438 is connected to the deflation pipe 437, and the other end of the deflation pipe 437 is connected to the air outlet end of the one-way valve 434, for example, between the one-way valve 434 and the posture adjustment pipeline 250. When the solenoid valve 438 is in the closed state, the one-way valve 434 is used to unidirectionally deliver the air generated by the air pump body 410 to the posture adjustment pipeline 250. When the solenoid valve 438 is in the open state, the posture adjustment pipeline 250 is deflated by the solenoid valve 438. In the specific structure, a first connecting pipe 431 is connected to the air outlet of the air pump body 410. A pressure reducing valve 432 is connected to the first connecting pipe 431. A second connecting pipe 433 is connected to the air outlet of the pressure reducing valve 432. The other end of the second connecting pipe 433 is connected to a one-way valve 434. A third connecting pipe 435 is connected to the air outlet of the one-way valve 434. A three-way connector 436 is connected to the third connecting pipe 435. One port of the three-way connector 436 is used to connect to the posture adjustment pipeline 250, and the other port of the three-way connector 436 is used to connect to a vent pipe 437. The vent pipe 437 is connected to a solenoid valve 438, and the outlet of the solenoid valve 438 is open to the outside air. The solenoid valve 438 has a closed state and an open state. When the solenoid valve 438 is in the closed state, the vent pipe 437 is blocked, thereby realizing inflation. When the solenoid valve 438 is in the open state, the vent pipe 437 is opened, thereby realizing deflation. The one-way valve 434 can be controlled by a switch, which is located on the outer wall of the control box for easy access by medical staff.

[0052] Similarly, the pluggable tubing of the turning airbag 300 can also be controlled in the same way. The pluggable tubing can be the first turning tubing 311 and / or the second turning tubing 331. However, the first turning tubing 311 and / or the second turning tubing 331 on the turning airbag 300 can be plugged into the tee connector 436.

[0053] like Figure 1 , Figure 3 As shown, the air pump assembly 400 in this embodiment further includes a hook 440, through which the air pump assembly 400 is connected to the bedside. This facilitates the installation of the air pump assembly 400 and allows it to be easily used by placing it beside the bed.

[0054] Compared with existing clinical solutions that commonly address postural issues and turning over:

[0055] Existing methods use multiple pillows of various sizes and shapes to achieve proper posture for different parts of the body, such as the shoulders, hips, and legs. This is difficult to implement in clinical practice, requiring a large number of procedures daily, with patients needing to be turned approximately every two hours, necessitating pillow placement and relying entirely on manual labor for turning. The proposed solution, however, uses a flexible mattress with an air pump component to easily meet these needs. It can be folded down into a small volume, making it easy to carry and promote. This mattress significantly helps hemiplegic patients achieve proper posture and effortless turning, truly fulfilling the service patients need.

[0056] It should be understood that the application of this application is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
