Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a portable inflatable lumbar support for medical use. Background Technology

[0002] For most people today, prolonged sitting at a desk has become the norm. When poor posture occurs, the lumbar spine becomes kyphotic, increasing the posterior intervertebral space. The nucleus pulposus in the intervertebral disc can protrude posteriorly, compressing the spinal nerves. Over time, this posture can lead to lumbar spine diseases. Lumbar supports, as a commonly used conservative treatment, are widely applied. They are mainly suitable for those with mild symptoms or those with obvious symptoms that can be relieved by rest. In addition, lumbar immobilization is also necessary after lumbar spine surgery. Choosing a suitable lumbar support can help patients recover and consolidate the therapeutic effect.

[0003] However, in existing technologies, when using lumbar supports for lumbar spine protection, an inflatable airbag is often added internally to improve overall comfort. For example, Chinese patent CN112244566A discloses an electric inflatable lumbar pillow, including a pillow body, a belt, an electric inflation device, and a magnetic positioning self-locking device. The electric inflation device has a metal shell, a charging interface, and a power supply interface, and is magnetically connected to the locking seat on the pillow body via a permanent magnet, and is detached and reattached through the magnetic positioning self-locking device. This invention can automatically inflate anytime, anywhere. When the electric inflation device has sufficient power, it can charge mobile phones and other electronic products through its power supply interface, functioning as a power bank. When not in use, the pillow body can be deflated and folded for easy storage. The electric inflation device is detachably connected to the pillow body, making it less likely to be lost. It also enables real-time monitoring and reminders of sitting posture.

[0004] While the above solutions have the advantages mentioned above, their disadvantages are that the length of the external support frame of the lumbar pillow is not adjustable, and the support and protection area cannot be adjusted in a timely manner for patients with lumbar spine diseases of different body types. Summary of the Invention

[0005] The purpose of this invention is to solve the problem in the prior art that the external support frame of the lumbar pillow is not adjustable in length, and the support and protection area cannot be adjusted in a timely manner for patients with lumbar spine diseases of different body types.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a portable medical inflatable lumbar support, comprising: a waistband, wherein multiple support grooves are fixedly connected to one side of the outer surface of the waistband, multiple protective airbags are movably installed on the inner wall of the waistband, multiple Velcro strips are fixedly installed inside the waistband, multiple connecting posts are fixedly installed on one side of the outer surface of one of the protective airbags, a motor is fixedly connected to one end of the outer surface of each of the multiple connecting posts, multiple side air cushions are movably installed on the inner wall of the waistband, and a one-way valve is fixedly embedded inside each of the multiple protective airbags. A side shaft is movably embedded on one side of the outer surface of each of the protective airbags, and a rotating shaft is movably embedded on one side of the outer surface of each of the multiple protective airbags. Adjacent side shafts are fixedly connected to the rotating shafts. The output shaft of the motor is fixedly connected to the adjacent rotating shaft. Multiple connecting seats are fixedly installed on one side of the inner wall of each of the multiple protective airbags. The connecting seats are movably sleeved on the outer surface of the rotating shafts. Centrifugal balls are fixedly sleeved on the outer surface of each of the multiple rotating shafts. V-shaped connecting straps are fixedly connected to both sides of the outer surface of each of the multiple support grooves. Fastening straps are fixedly connected to one side of the outer surface of each of the multiple V-shaped connecting straps.

[0007] In a preferred embodiment, a bottom plate is movably embedded in the inner wall of each of the multiple support grooves, and a top plate is movably embedded in the inner wall of each of the multiple support grooves. The top plate is movably connected to the bottom plate, and a fixing row is fixedly connected to one end of the outer surface of each of the multiple bottom plates.

[0008] The technical effect of adopting the above-mentioned further solution is that the cooperation of the bottom plate and the top plate provides external support for the lumbar spine, compensates for the stress on the lumbar intervertebral discs, relieves the accumulation of joint stress, and stabilizes the joints.

[0009] In a preferred embodiment, the inner walls of the plurality of fixed rows are movably fitted with ratchet teeth, and one end of the outer surface of the plurality of base plates is fixedly connected with a fixing plate.

[0010] The technical effect of adopting the above-mentioned further solution is that the fixing plate provides bottom support for the first springs on both sides, which facilitates the subsequent connection between the bottom plate and the top plate.

[0011] In a preferred embodiment, a first spring is fixedly connected to one side of the outer surface of each of the plurality of ratchet teeth, and the first spring is fixedly connected to the fixing plate.

[0012] The technical effect of adopting the above-mentioned further solution is that the cooperation between the fixing plate and the first spring makes it easier for the bottom plate to be inserted into the top plate and locked together. At the same time, the ratchet teeth will not fall off after locking, thus improving the connection stability.

[0013] In a preferred embodiment, the inner walls of the multiple top plates are provided with multiple ratchet teeth, and the interior of the multiple top plates is movably fitted with multiple abutments.

[0014] The technical effect of adopting the above-mentioned further solution is that when it is necessary to adjust the position of the base plate inside the top plate, press the abutment, the abutment abuts against the side frame of the ratchet, and then push the entire ratchet to slide on the inner wall of the fixed row, so that the ratchet and the ratchet teeth are disengaged, so that the base plate can be pulled and adjusted.

[0015] In a preferred embodiment, one end of the outer surface of each of the plurality of one-way valves is movably connected to an air hole, one end of the outer surface of each of the plurality of air holes is fixedly connected to an air supply pipe, one end of the outer surface of the air supply pipe is fixedly connected to a pipe plug, and the pipe plug is fixedly installed on the outer surface of the waistband.

[0016] The technical effect of adopting the above-mentioned further solution is that multiple air holes, through connection with one-way valves, can simultaneously inflate each protective airbag when an external air pump pressurizes air through the connecting pipe plug.

[0017] In a preferred embodiment, one end of each of the outer surfaces of the plurality of side shafts is fixedly connected to a plurality of first pivot plates, and one end of each of the outer surfaces of the plurality of first pivot plates is movably connected to a ball shaft.

[0018] The technical effect of adopting the above-mentioned further solution is that the cooperation between the first pivot plate and the ball shaft can drive the rotation of the ball shaft under the rotation of the side shaft.

[0019] In a preferred embodiment, the outer surfaces of the plurality of rotating shafts are threaded with threaded sleeves, one end of the outer surface of the plurality of threaded sleeves is fixedly installed with a slip ring, and the outer surfaces of the plurality of threaded sleeves are movably fitted with shaft sleeves.

[0020] The technical effect of adopting the above-mentioned further solution is that the cooperation between the threaded sleeve and the bushing ensures that the side motor can drive multiple rotating shafts to rotate, while facilitating the connection of the rotating shafts. The side rotating shafts can be connected after the protective airbag is fitted and fixed.

[0021] In a preferred embodiment, the inner walls of the plurality of bushings are provided with annular grooves, the slip ring is slidably embedded in the inner wall of the annular groove, and a second spring is fixedly connected to one side of the inner wall of the plurality of bushings, the second spring being fixedly connected to the slip ring.

[0022] The technical effect of adopting the above-mentioned further solution is that the cooperation between the slip ring and the second spring prevents the threaded sleeve from continuously oscillating inside the bushing, thus providing stability at the connection.

[0023] In a preferred embodiment, a plurality of second pivot plates are fixedly installed at one end of the outer surface of the plurality of bushings, and the second pivot plates are movably connected to the ball shaft.

[0024] The technical effect of adopting the above-mentioned further solution is that the movable second pivot plate cooperates with the ball shaft and the first pivot plate, and can continuously transmit rotation while changing the angle of the connection between the adjacent side shaft and the rotating shaft, which facilitates the rotation of multiple centrifugal balls in the future.

[0025] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0026] 1. In this invention, multiple protective airbags form multiple air chambers to form a waist cushion, which provides cushioning while being easy to disassemble. At the same time, if one protective airbag leaks air, it will not affect the other protective airbags.

[0027] 2. This invention, by using the abutment column to push away the interlocking ratchet teeth and fangs, allows for adjustment of the connection length between the bottom plate and the top plate, thereby increasing the external support area of ​​the lumbar support. The support area of ​​the support groove can be adjusted according to the patient's body shape, preventing situations where a long support groove injures the upper lumbar spine or a short support groove is insufficient to provide adequate support. This solves the problem in existing lumbar pillows where the external support frame is not adjustable, making it impossible to adjust the support and protection area in a timely manner for patients with lumbar spine diseases of different body types.

[0028] 3. This invention massages the patient's waist by rotating the shaft. While the protective airbag provides support and protection, the centrifugal ball taps and massages the patient's waist, providing the functionality of a lumbar support. The waistband is connected to the outside of the waistband by fastening straps, which can be connected by Velcro to adjust the tightness of the waistband and improve the wearer's comfort.

[0029] 4. In this invention, the rotation of the rotating shaft on the adjacent protective airbag is driven by the cooperation of the first pivot plate on the side of the side shaft with the ball shaft and bushing. This allows the centrifugal balls inside multiple protective airbags to rotate by adding a motor on only one side, saving production costs. At the same time, it allows for synchronous angular rotation at the connection between the upper and lower side shafts and the rotating shaft, which facilitates the wearer's bending and wrapping, improving the wearer's comfort.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figure 1-7This invention provides a technical solution: a portable medical inflatable lumbar support, comprising: a waistband 1, with multiple support grooves 2 fixedly connected to one side of the outer surface of the waistband 1; multiple protective airbags 3 movably installed on the inner wall of the waistband 1; multiple Velcro strips 301 fixedly installed inside the waistband 1; multiple connecting posts 401 fixedly installed on one side of the outer surface of one protective airbag 3; a motor 4 fixedly connected to one end of the outer surface of each of the multiple connecting posts 401; multiple side air cushions 5 movably installed on the inner wall of the waistband 1; a one-way valve 6 fixedly embedded inside each of the multiple protective airbags 3; a side shaft 7 movably embedded on one side of the outer surface of each of the multiple protective airbags 3; and a rotating shaft 8 movably embedded on one side of the outer surface of each of the multiple protective airbags 3. The side shaft 7 and the rotating shaft 8 of the same protective airbag 3 are fixed. The motor 4's output shaft is fixedly connected to the adjacent rotating shaft 8. Multiple connecting seats 10 are fixedly installed on one side of the inner wall of multiple protective airbags 3. The connecting seats 10 are movably sleeved on the outer surface of the rotating shaft 8. Centrifugal balls 11 are fixedly sleeved on the outer surface of multiple rotating shafts 8. V-shaped connecting straps 101 are fixedly connected to both sides of the outer surface of multiple support grooves 2. Fastening straps 102 are fixedly connected to one side of the outer surface of multiple V-shaped connecting straps 101. The waist support includes a waistband 1 and support grooves 2. The waistband 1 is divided into two pieces connected by Velcro strips 301. These two pieces are collectively referred to as waistband 1 for ease of subsequent description. The waistband 1 is filled with side air cushions 5. The protective airbags 3 and side air cushions 5 can also be connected by Velcro for easy connection of the protective airbags 3. The system is designed for independent disassembly. During disassembly, the rotating shaft 8 rotates inside the protective airbag 3, gradually disengaging from the threaded sleeve 801. The threaded sleeve 801 is slidably connected inside the bushing 9. Since the protective airbag 3 is fixedly positioned inside the waistband 1, the engagement between the threaded sleeve 801 and the bushing 9 ensures that the side motor 4 can drive multiple rotating shafts 8 to rotate while facilitating the connection of the rotating shafts 8. The side rotating shafts 8 can be connected after the protective airbag 3 is fixed in place. Multiple protective airbags 3 form multiple air chambers to create a waist pad, providing cushioning and facilitating disassembly. Furthermore, a leak in one protective airbag 3 will not affect the other protective airbags 3. A connectable base plate 201 and top plate 202 are inserted inside the support groove 2. The base plate 201 and top plate 202... 02 can be made of semi-rigid aluminum alloy strips or medical fiber plastic strips to support and protect the lumbar spine, while also restricting its range of motion. Compared to the above technical solutions, by using the abutment column 208 to push away the interlocking ratchet teeth 207 and 204, the connection length between the base plate 201 and the top plate 202 can be adjusted, thereby increasing the external support area of ​​the lumbar support 1. The support area of ​​the support groove 2 can be adjusted according to the patient's body shape, preventing situations where the support groove 2 is too long and injures the upper lumbar spine, or too short and does not provide sufficient support. The protective airbag 3 contains multiple centrifugal balls 11, which are placed on the back, not all around the circumference. The rotation of the pivot 8 massages the patient's waist.While providing support and protection, the protective airbag 3 also provides a lumbar support function by tapping and massaging the patient's lower back through the centrifugal ball 11. The lumbar support 1 is connected to the outside of the waistband 1 via fastening straps 102, which can be secured with Velcro to adjust the tightness of the waistband and prevent excessive contact and friction with the pelvis, thus increasing intra-abdominal pressure and improving wearer comfort. Furthermore, the fixing points of the protective airbag 3 to the rotating shaft 8, side shaft 7, and motor 4 are all made of rigid materials to prevent loosening at the connections and improve the overall stability of the device. The output shaft of motor 4 rotates, driving the adjacent rotating shaft 8 to rotate, which in turn drives the adjacent side shaft 7 to rotate. Through the cooperation of the first pivot plate 701 on the side of side shaft 7 with ball shaft 702 and bushing 9, the rotating shaft 8 on the adjacent protective airbag 3 is driven to rotate. This allows for the rotation of the centrifugal balls 11 inside multiple protective airbags 3 with only one side of motor 4, saving production costs while enabling synchronous angular rotation at the connection points of the upper and lower side shafts 7 and rotating shaft 8. This facilitates bending and wrapping around the wearer, improving comfort.

[0041] Please see Figure 1-7 The inner walls of multiple support grooves 2 are movably fitted with bottom plates 201 and top plates 202. The top plates 202 are movably connected to the bottom plates 201. One end of the outer surface of the multiple bottom plates 201 is fixedly connected with a fixing row 203. The cooperation of the bottom plates 201 and the top plates 202 provides external support for the lumbar spine, compensates for the stress on the lumbar intervertebral discs, relieves the accumulation of joint stress, and stabilizes the joints.

[0042] Please see Figure 1-7 The inner walls of multiple fixed rows 203 are movably fitted with ratchet teeth 204, and one end of the outer surface of multiple base plates 201 is fixedly connected with a fixing plate 205. The fixing plate 205 provides bottom support for the first springs 206 on both sides, which facilitates the subsequent connection between the base plate 201 and the top plate 202.

[0043] Please see Figure 1-7 Each of the multiple ratchet teeth 204 has a first spring 206 fixedly connected to one side of its outer surface. The first spring 206 is fixedly connected to the fixing plate 205. The cooperation between the fixing plate 205 and the first spring 206 makes it easier for the bottom plate 201 to be inserted into the top plate 202 for engagement. At the same time, the ratchet teeth 207 and ratchet teeth 204 will not fall off after engagement, thus improving the connection stability.

[0044] Please see Figure 1-7Multiple top plates 202 have multiple ratchet teeth 207 on their inner walls, and multiple abutment posts 208 are movably embedded inside the multiple top plates 202. When it is necessary to adjust the position of the bottom plate 201 inside the top plate 202, press the abutment post 208. The abutment post 208 abuts against the side frame of the ratchet tooth 204 and then pushes the entire ratchet tooth 204 to slide on the inner wall of the fixed row 203, so that the engagement between the ratchet tooth 204 and the ratchet tooth 207 is canceled, so that the bottom plate 201 can be pulled out for adjustment.

[0045] Please see Figure 1-7 One end of the outer surface of multiple one-way valves 6 is movably connected to an air hole 601, and one end of the outer surface of multiple air holes 601 is fixedly connected to an air supply pipe 602. One end of the outer surface of the air supply pipe 602 is fixedly connected to a pipe plug 603. The pipe plug 603 is fixedly installed on the outer surface of the waistband 1. Through the connection of multiple air holes 601 with one-way valves 6, each protective airbag 3 can be inflated synchronously when an external air pump presses air through the connecting pipe plug 603.

[0046] Please see Figure 1-7 Multiple first pivot plates 701 are fixedly connected to one end of the outer surface of multiple side shafts 7, and ball shafts 702 are movably connected to one end of the outer surface of multiple first pivot plates 701. The cooperation between the first pivot plates 701 and the ball shafts 702 can drive the ball shafts 702 to rotate under the rotation of the side shafts 7.

[0047] Please see Figure 1-7 The outer surfaces of multiple rotating shafts 8 are threaded with threaded sleeves 801, and one end of the outer surface of each threaded sleeve 801 is fixedly installed with a slip ring 802. The outer surfaces of multiple threaded sleeves 801 are movably fitted with bushings 9. The cooperation between the threaded sleeves 801 and the bushings 9 ensures that the side motor 4 can drive the multiple rotating shafts 8 to rotate, while facilitating the connection of the rotating shafts 8. The side rotating shafts 8 can be connected after the protective airbag 3 is fitted and fixed.

[0048] Please see Figure 1-7 The inner walls of multiple bushings 9 are provided with annular grooves 901. Slip rings 802 are slidably embedded in the inner walls of the annular grooves 901. A second spring 803 is fixedly connected to one side of the inner wall of multiple bushings 9. The second spring 803 is fixedly connected to the slip ring 802. The cooperation between the slip ring 802 and the second spring 803 prevents the threaded sleeve 801 from continuously swinging in the bushing 9 and provides stability at the connection.

[0049] Please see Figure 1-7 Multiple second pivot plates 902 are fixedly installed on one end of the outer surface of multiple bushings 9. The second pivot plates 902 are movably connected to the ball shaft 702. The movably connected second pivot plates 902 and ball shaft 702 cooperate with the first pivot plate 701. While changing the angle at the connection between the adjacent side shaft 7 and the rotating shaft 8, rotation transmission can be continuously carried out, which facilitates the rotation of multiple centrifugal balls 11 in the future.

[0050] Working principle

[0051] The lumbar support includes a waistband 1 and a support groove 2. The waistband 1 is divided into two pieces connected by Velcro strips 301. These two pieces are collectively referred to as waistband 1 for ease of subsequent description. The waistband 1 is filled with side air cushions 5. The protective airbags 3 and side air cushions 5 are also connected by Velcro, facilitating the individual removal of the protective airbags 3. During removal, the rotating shaft 8 is turned inside the protective airbag 3, gradually disengaging from the threaded sleeve 801. The threaded sleeve 801 is slidably connected inside the bushing 9. Since the protective airbag 3 is fixedly attached to the inside of the waistband 1, the engagement of the threaded sleeve 801 and the bushing 9 ensures that the side motor 4 can drive multiple rotating shafts 8 to rotate while facilitating the connection of the rotating shafts 8, thus protecting the airbags. After the protective airbags 3 are fitted and fixed, the side pivot 8 is connected. Multiple protective airbags 3 form multiple air chambers to form a lumbar cushion, providing cushioning while facilitating disassembly. Furthermore, a leak in one protective airbag 3 will not affect the others. A connectable base plate 201 and top plate 202 are inserted into the support groove 2. The base plate 201 and top plate 202 can be made of semi-hard aluminum alloy strips or medical fiber plastic strips, providing support and protection for the lumbar spine while also restricting lumbar spine mobility. Compared to the above technical solution, by using the abutment column 208 to push away the interlocking ratchet teeth 207 and 204, the connection length between the base plate 201 and top plate 202 can be adjusted, thereby increasing the external support area of ​​the lumbar support 1. The support area of ​​the support groove 2 is adjusted according to the patient's body shape to avoid situations where the support groove 2 is too long and injures the upper lumbar spine, or too short and does not provide sufficient support. The protective airbag 3 contains multiple centrifugal balls 11, positioned on the back, not all around the entire circumference. The rotation of the pivot 8 massages the patient's lower back. While the protective airbag 3 provides support and protection, the centrifugal balls 11 provide a tapping and massaging effect on the patient's lower back, offering lumbar support functionality. The waistband 1 is connected externally by fastening straps 102, which can use Velcro to adjust the tightness of the waistband, preventing excessive contact and friction with the pelvis, thus avoiding increased intra-abdominal pressure and discomfort for the wearer. For comfort, the fixed positions of the airbag 3 connecting shaft 8, side shaft 7, and motor 4 are all made of rigid materials to prevent loosening at the connection points and improve the stability of the overall device. The rotation of the output shaft of the side motor 4 drives the rotation of the adjacent shaft 8, which in turn drives the rotation of the adjacent side shaft 7. Through the cooperation of the first pivot plate 701 on the side of the side shaft 7 with the ball shaft 702 and bushing 9, the rotation of the shaft 8 on the adjacent protective airbag 3 is driven. Thus, the centrifugal ball 11 inside multiple protective airbags 3 can be rotated by adding a motor 4 on only one side, which saves production costs and allows for synchronous angular rotation at the connection points of the upper and lower side shafts 7 and shaft 8, making it convenient for the wearer to bend and wrap around, thus improving the wearer's comfort.

[0052] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
