Description

Technical Field

[0001] This utility model belongs to the field of rehabilitation medical device technology, and in particular relates to a pillow that promotes the relief and rehabilitation of cervical spondylosis. Background Technology

[0002] Cervical spondylosis is a disease caused by long-term strain on the cervical spine, bone hyperplasia, intervertebral disc herniation, ligament thickening, and other degenerative factors, leading to compression of the cervical spinal cord, nerve roots, vertebral arteries, and other parts of the body. Different types of cervical spondylosis will have different clinical manifestations, but they usually include neck and back pain and stiffness, frequent dizziness, nausea and vomiting, and may even be accompanied by blurred vision, tachycardia, difficulty swallowing, limb numbness, memory loss, and worsening sleep.

[0003] Cervical spondylosis is common among people who spend long hours working at desks or with their heads down, especially office workers and those who use mobile phones and computers. The incidence rate is increasing year by year and is rapidly spreading to younger people.

[0004] Currently, there is much research on the role of pillows in relieving symptoms and aiding rehabilitation for patients with cervical spondylosis. Numerous studies have shown that providing personalized and effective support for the head and neck, maintaining the correct physiological curvature of the cervical spine to ensure a comfortable sleeping posture, and ensuring full relaxation of the posterior neck muscles are among the effective means of relieving and aiding the rehabilitation of cervical spondylosis during sleep.

[0005] Due to significant differences in physiological states, sleep habits, and physical conditions among individuals, cervical spondylosis patients have vastly different requirements regarding pillow height, tilt direction and angle, relative position between the head and neck pillows, softness, fit to the head and neck, and support points. Furthermore, the ideal sleeping posture changes with the duration of sleep. Therefore, for cervical spondylosis patients, a pillow with comprehensive and multi-dimensional adjustable functions is crucial.

[0006] Currently, there are two main technical approaches to adjusting pillow parameters and functions based on motion:

[0007] The first type is achieved through the design of mechanical transmission principles, including power devices, rotating devices, actuators, and even control systems. Examples include patents CN202220725961.9 (pillow), CN201721229706.0 (an adjustable pillow), CN202410552588.5 (an adjustable slope pillow), and CN202410399009.8 (a pillow for correcting cervical curvature). In this type of method, the pillow becomes a mechanical device, characterized by numerous parts, a complex structure, a complex transmission mechanism, mechanical noise, bulkiness, and limited adjustment dimensions, making it difficult to fully meet the multi-dimensional adjustment needs of various cervical spine patients.

[0008] The second type utilizes the expansion and contraction of air bladders to replace mechanical transmission, greatly simplifying the transmission mechanism. The volume and firmness of the air bladder are changed directly by inflating and deflating it, thus altering the pillow's parameters. Examples include CN202410824448.9 (A silent, height-adjustable intelligent pillow and its control method), CN202311840694.5 (An anti-snoring pillow), CN201810211614.2 (An automatically height-adjustable, anti-snoring interchangeable combination pillow), CN202311864387.0 (pillow), CN202311865651.2 (pillow for anti-snoring), CN202311865655.0 (pillow), and CN202311864380.9 (pillow). In this type of method, the airbag filled with pressurized air is both the power unit and often part of the filling core. Its characteristics are: relatively simple structure, more adjustable parameters, more flexibility and gentler operation, and the power part and the execution part can be separated. For example, the air compression mechanism can be separated from the pillow. However, the control system and pipelines are complex, and sometimes there is pneumatic noise.

[0009] Given the increasing proportion of cervical spondylosis patients and the rapid trend of patients becoming younger, it is of great significance to develop a pillow that can be adjusted in multiple parameters and dimensions to better suit the sleeping posture of cervical spondylosis patients, thereby promoting the relief and recovery of cervical spondylosis symptoms.

[0048] Example 1

[0049] Embodiment 1 of this utility model proposes a pillow that promotes the relief and recovery of cervical spondylosis, such as... Figure 1 , Figure 2 As shown, it includes a base box 2, a support plate 4, and a head support plate 6:

[0050] The structure of the bottom box 2 is as follows: Figure 3 As shown, it includes a bottom panel 201, which has a central hole 205 and a surrounding ring plate 203. The bottom panel 201 and the surrounding ring plate 203 form an open-facing cavity. The surrounding ring plate 203 has a pipeline hole 201 and a neck support airbag seat 206. The bottom box 2 also has a pull-down seat 203.

[0051] The central hole 205 is used to facilitate maintenance and allow air to circulate inside the pillow; the pipeline hole 201 is used to allow pressurized air pipes and cables connecting the inside and outside of the pillow to pass through.

[0052] The structure of the support plate 4 is as follows: Figure 4As shown, the device includes an upper panel 401, around which are two opposing arc-shaped side plates 405 and two opposing straight side plates 410. The upper panel 410, arc-shaped side plates 405, and straight side plates 410 form an open-faced cavity. The upper panel 401 has an upper concave spherical surface 407 and a central pull seat 402. The upper side of the upper panel 401 has an airbag limiting seat 403, and the lower side has a limiting ring 408. The outer side of the limiting ring 408 and the inner side of the arc-shaped side plates 405 and straight side plates 410 form an annular airbag limiting groove 409. The upper concave spherical surface 407 has a bearing mounting groove 406. The centers of the two arc-shaped side plates 405 coincide. The arc-shaped side plates 405 and straight side plates 410 have through holes 404.

[0053] The centers of the two arc-shaped side plates 405 coincide, which allows the bearing plate 4 to rotate a certain angle within the base box 2. The airbag limiting seat 403 and the airbag limiting groove 409 are used to prevent the airbag from sliding or tilting during use and causing malfunctions. The through hole 404 is used for cables and pipes to pass through and for ventilation. The concave spherical surface 407 forms part of the ball joint and bears the pressure from the head support plate 6.

[0054] The structure of the head support plate 6 is as follows: Figure 5 As shown, it includes a head-down plate 601, on which an upper pull seat 603 is provided. The upper side of the head-down plate 601 has a downwardly slightly concave area 602, and the lower side has a downwardly convex spherical surface 604. A cavity 605 is left between the concave area 602 and the downwardly convex spherical surface 604.

[0055] The recessed area 602 serves to improve the fit between the user's head and the pillow, thereby enhancing comfort; the cavity 605 serves to reduce the weight of the pillow; and the convex spherical surface 604 serves to form part of the ball joint, transferring the load and weight of the headrest plate 6 to the support plate 4.

[0056] During installation, Figure 1 , Figure 2 Based on this, see in sequence Figures 7 to 11 The support plate 4 is located inside the cavity of the bottom box 2 and below the head support plate 6; the support plate 4 can move parallel in the up-down and back-forward directions and rotate in the horizontal direction relative to the bottom box 2.

[0057] The space inside the base box 2 and outside the support plate 4 is provided with four sets of horizontally movable push airbags 3 and air valve assemblies 5; one end of the push airbag 3 abuts against the inner wall of the ring plate 204, and the other end abuts against the outer wall of the straight side plate 410.

[0058] The first horizontal airbag 301 is located at the front right of the bottom box 2, the second horizontal airbag 302 is located at the front left, the third horizontal airbag 303 is located at the rear left, and the fourth horizontal airbag 304 is located at the rear left. The air valve assembly 5 is located at the front of the bottom box 2. The neck support airbag seat 206 is located at the front side of the bottom box 2. All the horizontal airbags 3 have one end that mates with the inner side of the ring plate 204 and the other end that mates with the outer side of the straight side plate 410. If the first horizontal airbag 301 and the second horizontal airbag 302 inflate simultaneously, and the third horizontal airbag 303 and the fourth horizontal airbag 304 deflate simultaneously, the support plate 4 can be pushed backward. If the first horizontal airbag 301 and the third horizontal airbag 303 inflate simultaneously, and the second horizontal airbag 302 and the fourth horizontal airbag 304 deflate simultaneously, the support plate 4 can be rotated horizontally.

[0059] The lifting airbag 12 and control unit 15 are located inside the space on the inner side of the base box 2 and the lower side of the support plate 4. A signal line connects the control unit to the air valve assembly. The structure of the lifting airbag 12 is as follows: Figure 6 As shown, the whole is ring-shaped and can move up and down. It has at least two parallel planes, the upper plane of which cooperates with the lower side of the upper panel 401 and is located in the airbag limiting groove 409, and the lower plane cooperates with the upper side of the bottom panel 201. If the lifting airbag 12 is inflated, it will lift the support plate 4 upward.

[0060] The bearing plate 4 and the head support plate 6 are connected by an upper concave spherical surface 407 and a lower convex spherical surface 604, allowing the head support plate 6 and the bearing plate 4 to rotate in any direction and within a certain angle range. In order to reduce friction and prevent noise from being generated when sliding relative to each other, a sliding bearing 16 is provided between the upper concave spherical surface 407 and the lower convex spherical surface 604. The sliding bearing 16 is located in the bearing mounting groove 406. The sliding bearing 16 is made of odorless, harmless, and stable graphite or nylon material.

[0061] The device is equipped with four sets of tilt-adjustable airbags 14 that can move up and down. All tilt-adjustable airbags 14 have their upper ends engaged with the lower side of the headrest plate 601 and their lower ends engaged with the upper side of the upper panel 401. Specifically, the first tilt-adjustable airbag 141 is located to the right front of the pillow user, the second tilt-adjustable airbag 142 is located to the left front, the third tilt-adjustable airbag 143 is located to the lower left, and the fourth tilt-adjustable airbag 144 is located to the lower right. If the first tilt-adjustable airbag 141 and the second tilt-adjustable airbag 144 are positioned... The tilt adjustment airbag 142 inflates synchronously, and the third tilt adjustment airbag 143 and the fourth tilt adjustment airbag 144 deflate and contract synchronously, which allows the headrest plate 6 to tilt back and forth around its lower convex spherical surface 604; if the first tilt adjustment airbag 141 and the fourth tilt adjustment airbag 144 inflate synchronously, and the second tilt adjustment airbag 142 and the third tilt adjustment airbag 143 deflate and contract synchronously, the headrest plate 6 can tilt left and right around its lower convex spherical surface 604.

[0062] Multiple first elastic bands 7 are provided between the support plate 4 and the headrest plate 6 to keep them flexibly connected; the upper end of the first elastic band 7 is connected to the upper pull seat 603, and the other end is connected to the middle pull seat 402; after installation, the first elastic band 7 is kept with a certain pre-tight tension, so that the headrest plate 6 and the support plate 4 remain stable, and also so that when the tilt adjustment airbag 14 is inflated, the corresponding part of the head plate 601 rises smoothly and gently, and when it is deflated, the corresponding part of the head plate 601 returns to its original position smoothly, thereby ensuring that the pillow has good shape recovery ability;

[0063] The base box 2 and the headrest 6 are also connected by multiple second elastic bands 8 to maintain a flexible connection between them; the upper end of the second elastic band 8 is connected to the upper pull seat 603, and the other end is connected to the lower pull seat 203; after installation, the second elastic band 8 maintains a certain pre-tension, so that the headrest 6 and the base box 2 remain stable, improve the pillow's ability to prevent damage from being thrown, and also make the inflation and deflation of the lifting airbag 12, the flat pushing airbag 3, and the tilt adjustment airbag 14 more gentle and smooth.

[0064] The neck support airbag seat 206 is provided with a neck support airbag 9, and the neck support airbag 9 is bound to the neck support airbag seat 206 by an elastic strap 18; when the neck support airbag 9 is inflated, it expands radially, that is, the diameter increases, the center line moves up, and the height increases.

[0065] The inflation and deflation deformation directions of the horizontal airbag 3, lifting airbag 12, and tilt adjustment airbag 14 are axial, while the inflation and deflation deformation direction of the neck support airbag 9 is radial. That is, the length of the horizontal airbag 3 changes in the horizontal direction, the height of the lifting airbag 12 and tilt adjustment airbag 14 changes in the vertical direction, and the diameter of the neck support airbag 9 changes. All airbags have two air tubes for inflation and deflation connected to the air valve assembly 5.

[0066] The air valve assembly 5 includes at least one intake manifold and one exhaust manifold. Both the intake manifold and the exhaust manifold are equipped with intake and exhaust manifolds connected to each airbag. A solenoid valve is provided between the intake and exhaust manifolds corresponding to each airbag. The solenoid valve is a three-position four-way valve, which enables each airbag to have three working conditions: inflation, pressure holding, and deflation. When inflating, the intake manifold is connected to the corresponding airbag. When deflation, the exhaust manifold is connected to the corresponding airbag. When holding pressure, neither the intake manifold nor the exhaust manifold is connected to the corresponding airbag.

[0067] The bottom box 2 and all components directly or indirectly installed on it are covered with soft filling material 1, which is then covered with pillow core cover 10 to form a pillow core; the pillow core is then covered with pillow cover 11 to form the pillow.

[0068] The principle of the above structure is as follows: Figures 12-15 As shown:

[0069] By inflating and deflating the lifting airbag 12, the height of the support plate 4 and the headrest plate 6 is raised or lowered to form the headrest lifting action 20, thereby realizing the adjustment of the height parameter of the headrest part of the pillow.

[0070] By combining the inflation and deflation actions between the airbags 3, the support plate 4 and the headrest plate 6 can be rotated to achieve the horizontal phase adjustment action 22 of the headrest part of the pillow, and the support plate 4 and the headrest plate 6 can be moved back and forth to achieve the neck pulling action 18 of the pillow.

[0071] By adjusting the angle of the airbags 14 in combination with inflation and deflation, the headrest 6 can be rotated and tilted left and right at a certain angle to achieve the left and right tilting action 21 of the pillow headrest, and the headrest 6 can also be rotated and tilted forward and backward at a certain angle to achieve the forward and backward tilting action 17 of the pillow headrest.

[0072] This allows the pillow to be adjusted in multiple parameters and dimensions to accommodate and adapt to the sleeping posture of patients with cervical spondylosis, maintain the appropriate physiological curvature of the cervical spine, and better relax the neck and shoulder muscles, thereby promoting the relief and recovery of cervical spondylosis symptoms.

[0073] The specific work process is as follows:

[0074] When adjusting the height of the headrest of the pillow: inflating the lifting airbag 12 increases its height, lifting the support plate 44 and headrest plate 6, thereby increasing the height of the headrest; conversely, deflating the lifting airbag 12 decreases its height, and the support plate 44 and headrest plate 6 descend, thereby reducing the height of the headrest.

[0075] When it is necessary to adjust the front-to-back tilt angle of the pillow headrest: inflating the two sets of tilt adjustment airbags 14 away from the shoulders (corresponding to the top of the head of the supine person) and deflating the two sets of tilt adjustment airbags 14 near the shoulders allows the headrest plate 6 to rotate along its lower convex spherical surface 604, raising the side away from the shoulders and lowering the side near the shoulders; conversely, deflating the two sets of tilt adjustment airbags 14 away from the shoulders and inflating the two sets of tilt adjustment airbags 14 near the shoulders allows the headrest plate 6 to lower the side away from the shoulders and raise the side near the shoulders; thus achieving the adjustment of the front-to-back tilt angle of the headrest.

[0076] When it is necessary to adjust the left and right tilt angle of the pillow headrest: inflating the two sets of tilt adjustment airbags 14 on the left (relative to the supine person) and deflating the two sets of tilt adjustment airbags 14 on the right, the headrest 6 can be rotated along its lower convex spherical surface 604, causing the left side of the headrest 6 to rise and the right side to fall; conversely, deflating the two sets of tilt adjustment airbags 14 on the left and inflating the two sets of tilt adjustment airbags 14 on the right, the left side of the headrest 6 can be lowered and the right side to rise; thus, the left and right tilt angle of the pillow can be adjusted.

[0077] When it is necessary to adjust the vertical (horizontal) phase (rotation angle) of the pillow headrest: inflating the two sets of horizontal airbags 3 (located diagonally opposite each other) that are far from the shoulder and on the left, and the two sets of horizontal airbags 3 that are close to the shoulder and on the right, while deflating the two sets of horizontal airbags 3 located at the other diagonal, allows the headrest plate 6 to rotate clockwise by one angle based on the top view under the action of the support plate 4; conversely, deflating the two sets of horizontal airbags 3 that are far from the shoulder and on the left, and the two sets of horizontal airbags 3 that are close to the shoulder and on the right, while inflating the two sets of horizontal airbags 3 located at the other diagonal, allows the headrest plate 6 to rotate counterclockwise by one angle based on the top view under the action of the support plate 4; thus achieving the vertical phase adjustment of the pillow headrest.

[0078] When adjusting the distance between the headrest and neck support of the pillow (neck traction): inflating the two sets of horizontal airbags 3 away from the shoulders and deflating the two sets of horizontal airbags 3 near the shoulders will cause the headrest 6 to move towards the neck support airbags 9, thereby shortening the distance between the headrest 6 and the neck support airbags 9; conversely, deflating the two sets of horizontal airbags 3 near and away from the shoulders and inflating the two sets of horizontal airbags 3 near the shoulders will cause the headrest 6 to move away from the neck support airbags 9, thereby increasing the distance between the headrest 6 and the neck support airbags 9; thus, the distance between the headrest 6 and the neck support airbags 9 can be adjusted.

[0079] When the height of the pillow's neck support needs to be adjusted: inflating the neck support bladder 9 causes it to expand and increase in diameter, thus increasing the height of the pillow's neck support under the constraint of the bladder seat; conversely, when the neck support bladder 9 deflates, it contracts and decreases in diameter, causing the height of the pillow's neck support to decrease, thereby achieving height adjustment of the neck support.

[0080] Compared to current technologies that only allow adjustment of a few parameters such as height and the tilt angle of the headrest and are structurally complex, the technology provided by this utility model allows for the adjustment of more parameters, including at least: making the pillow highly adaptable and accommodating to the sleeping posture of patients with cervical spondylosis, thereby improving comfort, promoting the maintenance of the proper physiological curvature of the cervical spine, and thus better promoting the relief and recovery of cervical spondylosis symptoms, etc., with significant advantages. Specifically:

[0081] (1) All movements are achieved by pneumatics, which is relatively smooth and gentle. In particular, for movements such as adjusting the tilt angle of the headrest and adjusting the pillow height, which are more sensitive to users, the elastic band has a certain pre-tightening. During the movement, the airbag needs to gradually overcome the tension of the elastic band, making the pillow adjustment movement smoother and gentler, and effectively overcoming the discomfort caused by the impact of the actuator movement.

[0082] (2) In addition to adjusting the height and the front-to-back tilt angle of the headrest, this utility model also adds functions such as adjusting the left-to-right tilt angle of the headrest, adjusting the phase on the horizontal plane, and neck traction, wherein:

[0083] The left and right tilt angle adjustment function is highly adaptable to the semi-lateral sleeping position, which can make it easier and more comfortable for some cervical spine patients who cannot lie completely on their back or side. It also helps to suppress snoring in supine people and prevent stiff neck from falling out of bed.

[0084] The phase adjustment function on the horizontal plane allows cervical spine patients to adjust the correct physiological curvature of the cervical spine while keeping their head flat when lying on their side. It also helps to solve problems such as snoring and sleep apnea syndrome in cervical spine patients.

[0085] Neck traction is very helpful in promoting neck muscle relaxation and improving the comfort of patients with cervical spondylosis.

[0086] (3) The “soft on the outside and firm on the inside” design includes three important components: the bottom box 2, the support plate 4, and the head support plate 6. The bottom box 2 and the head support plate 6, as well as the support plate 4 and the head support plate 6, are connected by elastic bands and are pre-tightened. The bottom box 2 and the support plate 4 are provided with a lifting airbag 12 and a flat airbag 3, and the support plate 4 and the head support plate 6 are provided with an angle adjustment airbag 14, which has excellent cushioning ability. The neck support airbag 9 is locked to the bottom box 2 by a soft strap. This structural design makes the pillow provided by this utility model compact and stable, with strong load-bearing capacity, and not easily damaged by moving, lying down, throwing or throwing, while meeting the requirements of comfort and functionality.

[0087] (4) Each action can be implemented by switching the solenoid valve. The air pump that provides pressurized air can be integrated inside the pillow or placed outside the pillow. The internal control unit 15 can communicate with the outside via wired or wireless means. The technical solution provided by this utility model provides an excellent foundation platform for the future development of special function pillows.

[0088] Example 2

[0089] The difference between this embodiment and Embodiment 1 is that:

[0090] ① Structurally, the bottom box 2 and the support plate 4 described in Embodiment 1 are integrated into one unit to form the support base 23. Figure 1 Based on the above, see Figure 16 Four sets of tilt-adjustable airbags 14 and a first elastic band 7 are also provided between the support base 23 and the head support plate 6; the structure of the support base 23 is as follows Figure 17 As shown, it includes a support panel 231, and a side panel 232 is provided around the support panel. The side panel 232 is provided with a neck support airbag seat 206. The support panel 231 is provided with a structure similar to the center pull seat 402, airbag limiting seat 403, and upper concave spherical surface 407 on the upper panel 401.

[0091] ② In principle, in addition to adjusting the front-to-back and left-to-right tilt angles of the headrest 6 through the combined inflation and deflation of the four sets of tilt-adjusting airbags 14, the height of the headrest 4 is adjusted by the synchronous inflation and deflation of the four sets of tilt-adjusting airbags 14, thereby achieving the purpose of adjusting the pillow height parameters. Since the lower convex spherical surface 604 and the upper concave spherical surface 407 separate when the four sets of tilt-adjusting airbags 14 are simultaneously inflated and raised, the height adjustment range of the headrest 6 is limited.

[0092] Compared to Embodiment 1, although this embodiment cannot achieve the horizontal phase adjustment action 22 and the neck pulling action 18 of the headrest, it has the advantages of simple structure and lower cost.

[0093] The above description is the preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model. For example, the installation positions of the air valve assembly 5 and the control unit 15 can be adjusted, the number of lifting airbags 12 can be changed to multiple parallel or stacked, the upper concave spherical surface 407 and the lower convex spherical surface 604 can be adjusted to the upper convex spherical surface on the support plate 4 and the lower concave spherical surface on the headrest plate 6, etc., and if modifications are made, for example, a music playback device to promote sleep can be set inside the pillow, sensors with certain functions can be arranged, a heating device can be added to the neck support airbag (9), etc., these improvements and modifications should also be considered within the scope of protection of the present utility model.
