Description

Cervical traction care equipment Technical Field

[0001] The present application relates to the field of cervical vertebra health, and more specifically to cervical vertebra traction care equipment. Background Art

[0002] In recent years, cervical spine health has garnered increasing attention. Currently, a variety of methods and devices are used to maintain the cervical spine. For example, some cervical physiotherapy devices stretch the cervical spine or relax the cervical muscles by pressing, kneading, pinching, pushing, and pulling. However, these cervical physiotherapy devices present some practical challenges.

[0003] Specifically, existing cervical vertebrae therapy equipment mainly achieves the maintenance of the cervical spine by the movement of its local structure relative to the human body. Accordingly, many cervical vertebrae therapy equipment are provided with a movable part, which moves relative to the human body by driving the movable part to rotate, lift, translate, reciprocate, vibrate, etc. For example, existing cervical vertebrae therapy equipment is usually provided with a movable body that can move upward, and during the vertical rise of the movable body, it presses against and pushes the neck. In order to achieve the preset movement mode of the movable part, the structural design of the cervical vertebrae therapy equipment is relatively complex, which not only increases the manufacturing cost and difficulty, but also brings challenges to space utilization and control stability.

[0004] Some cervical physiotherapy devices are designed with multiple motion modes, increasing their structural complexity and manufacturing challenges. For example, to achieve the movement of the active part in different directions, some cervical physiotherapy devices are equipped with multiple drivers, multiple mounting platforms, and multiple movable adjustment components. To ensure the coordinated and stable movement of different active parts in different directions, high requirements are placed on the precision of each component and the structural coordination between them.

[0070] Schematic cervical traction care equipment

[0071] As mentioned above, existing cervical vertebrae therapy equipment mainly achieves the maintenance of the cervical spine by the movement of its local structure relative to the human body. Accordingly, many cervical vertebrae therapy equipment are provided with a movable part, which moves relative to the human body by driving the movable part to rotate, lift, translate, reciprocate, vibrate, etc. For example, existing cervical vertebrae therapy equipment is usually provided with a movable body that can move upward, and during the vertical rise of the movable body, it presses against and pushes the neck. In order to achieve the preset movement mode of the movable part, the structural design of the cervical vertebrae therapy equipment is relatively complex, which not only increases the manufacturing cost and difficulty, but also brings challenges to space utilization and control stability.

[0072] In the embodiments of the present application, it is proposed to achieve its preset motion modes through a relatively simple structural design to reduce its structural complexity and manufacturing difficulty. Specifically, the cervical traction care device of the present application realizes switching between different motion modes and switching between different modes of action on the user by coordinating the telescopic direction of the controllable telescopic body 20 acting on the user and the surface shape of the mounting shell 10, without the need for additional or large-scale addition of drive components and other components.

[0073] As shown in Figures 1 to 7, a cervical traction nursing device according to an embodiment of the present application is illustrated. The cervical traction nursing device includes a mounting housing 10 and at least one controllable telescopic body 20 mounted on the mounting housing 10, wherein the controllable telescopic body 20 is controllably switchable between an extended state and a retracted state. During the process of switching from the retracted state to the extended state, the controllable telescopic body 20 extends toward the side of the mounting housing 10, as shown in Figure 2. During the process of switching from the extended state to the retracted state, the controllable telescopic body 20 retracts from the side of the mounting housing 10 into the mounting housing 10. It is worth noting that in the embodiment of the present application, the controllable telescopic body 20 mainly emphasizes the feature that it can be extended or retracted relative to the mounting housing 10, including the case where the controllable telescopic body 20 itself has a retractable structure, such as a spring, and also includes the case where the controllable telescopic body 20 itself does not have a retractable structure but can be extended or retracted relative to the mounting housing 10 under the drive of a drive mechanism.

[0074] When the user rests his head on the cervical traction nursing device, the user's shoulders are located on the side of the cervical traction nursing device. When the controllable telescopic body 20 extends to the side of the mounting shell 10, the controllable telescopic body 20 presses against the user's shoulders to press the shoulders. When the controllable telescopic body 20 switches back and forth between the extended state and the retracted state, the controllable telescopic body 20 can press the user's shoulders multiple times, which can massage the shoulders and relieve shoulder fatigue.

[0075] Specifically, in an embodiment of the present application, the mounting housing 10 has at least one opening 122 corresponding to the controllable telescopic body 20, such that the controllable telescopic body 20 extends outward through the opening 122 when in the extended state. The mounting housing 10 includes an upper housing 12 and a lower housing 11 opposing each other. In a specific example of the present application, the opening 122 is formed in the upper housing 12. The upper housing 12 and the lower housing 11 may have a one-piece structure or a separate structure.

[0076] The mounting housing 10 further includes at least one side support wall formed between the upper housing 12 and the lower housing 11. The side support wall extends in a height direction Z set for the mounting housing 10. The height direction Z set for the mounting housing 10 is directed from the top surface of the upper housing 12 to the bottom surface of the lower housing 11, or from the bottom surface of the lower housing 11 to the top surface of the upper housing 12, as shown in FIG1 . The side of the mounting housing 10 forms an angle with the height direction set for the mounting housing 10, that is, the angle between the side of the mounting housing 10 and the height direction set for the mounting housing 10 is not equal to 0° or 180°.

[0077] In a specific example of the present application, the side support wall extends upward from the lower shell 11. It should be understood that the side support wall can also extend between the upper shell 12 and the lower shell 11 in other ways. For example, the side support wall extends downward from the upper shell 12. For another example, the side support wall is suspended between the upper shell 12 and the lower shell 11.

[0078] In this specific example, the mounting shell 10 includes two side support walls: a first side support wall 113 and a second side support wall 114 spaced apart in the longitudinal direction X of the mounting shell 10. The controllable telescopic body 20 is mounted on the side of the side support wall. When the controllable telescopic body 20 is in an extended state, the controllable telescopic body 20 extends outward from the side support wall. When a user rests their head on the cervical traction nursing device, the controllable telescopic body 20 provided on the first side support wall 113 and the controllable telescopic body 20 provided on the second side support wall 114 are pressed against the shoulders on both sides of the user's neck when they are in an extended state. It should be understood that in other specific examples of the present application, other numbers of side support walls may be provided.

[0079] In an embodiment of the present application, the controllable telescopic body 20 is implemented as an airbag 210. Accordingly, the controllable telescopic body 20 includes at least one airbag 210, and the airbag 210 expands toward the side of the mounting shell 10 while expanding, and in this way extends toward the side of the mounting shell 10. Specifically, a group of airbag assemblies are installed at each side support wall, and each airbag assembly includes at least one airbag 210. That is, the controllable telescopic body 20 includes at least one airbag assembly. In a specific example of the present application, the controllable telescopic body 20 includes a first airbag assembly 21 installed on the first side support wall 113 and a second airbag assembly 22 installed on the second side support wall 114, and the first airbag assembly 21 and the second airbag assembly 22 are arranged in the length direction of the mounting shell 10. In this specific example, each airbag assembly includes at least two airbags 210, and at least two airbags 210 are stacked along the side of the mounting shell 10 so that the airbags 210 extend along the side of the mounting shell 10 when inflated. The more airbags 210 stacked along the side of the mounting shell 10, the longer the length of the airbags 210 extending along the side of the mounting shell 10 when inflated, and the greater the force exerted on the user. The number, inflation speed, and inflation volume of the airbags 210 can be set according to needs.

[0080] When a set of the airbag assemblies includes at least two airbags 210, the at least two airbags 210 in the same airbag assembly are interconnected. Thus, the at least two airbags 210 in the same airbag assembly can be inflated by a single inflation device, thereby reducing the number of components in the cervical traction nursing device. Of course, the at least two airbags 210 are independently inflated and deflated.

[0081] In an embodiment of the present application, the cervical traction nursing device includes a telescopic control component 30 for controlling the telescopic extension of the controllable telescopic body 20. When the controllable telescopic body 20 is implemented as an airbag 210, the telescopic control component 30 can be implemented as an air pump. In a specific example of the present application, the telescopic control component 30 includes a first air pump 31 connected to at least one airbag 210 of the first airbag component 21 and a second air pump 32 connected to at least one airbag 210 of the second airbag component 22. The number, position, and connection method of the air pumps with each airbag 210 are not limited by the present application. For example, the airbag 210 of the first airbag component 21 and the airbag 210 of the second airbag component 22 can be inflated by the same air pump.

[0082] In a specific example of the present application, the first air pump 31 and the second air pump 32 are disposed between the upper housing 12 and the lower housing 11, as shown in FIG3 . In this specific example, the upper housing 12 has two receiving grooves 121. The first air pump 31 and the second air pump 32 are each at least partially embedded in the two receiving grooves 121 of the upper housing 12.

[0083] In this specific example, the first air pump 31 and the first airbag assembly 21 are located on opposite sides of the first side support wall 113, and the second air pump 32 and the second airbag assembly 22 are located on opposite sides of the second side support wall 114. The telescoping control assembly 30 includes a vent tube 33 connected between the first air pump 31 and the airbag 210 of the first airbag assembly 21, and a vent tube 33 connected between the second air pump 32 and the second airbag assembly 22. The first side support wall 113 and the second side support wall each have a through hole 102, which allows the vent tube 33 to pass through the first side support wall 113 and / or the second side support wall 114 and extend between the air pump and the airbag 210.

[0084] It should be understood that the controllable telescopic body 20 and the telescopic control component 30 may be implemented in other embodiments. For example, the telescopic control component 30 is implemented as a motor, and the motor drives the controllable telescopic body 20 to switch between the extended state and the retracted state.

[0085] For example, in a modified embodiment of the present application, as shown in Figure 5, the controllable telescopic body 20 includes a first controllable telescopic body 23 and a second controllable telescopic body 24, and the telescopic control component 30 includes a first screw motor 34 connected to the first controllable telescopic body 23 and a second screw motor 36 connected to the second controllable telescopic body 24.

[0086] In this modified embodiment, the first controllable telescopic body 23 and the second controllable telescopic body 24 are both made of rigid materials to provide sufficient force when they are against the user. Optionally, the surface of the first controllable telescopic body 23 and the surface of the second controllable telescopic body 24 have an outwardly protruding arc structure. When the controllable telescopic body 20 acts on the user, the arc structure faces the user's shoulder. Further optionally, the cervical traction care device also includes a first flexible sleeve cushion mounted on the first controllable telescopic body 23 and a second flexible sleeve cushion mounted on the second controllable telescopic body 24 to improve the user's comfort.

[0087] The first screw motor 34 includes a first motor body 341 and a first screw 342 connected to the first motor body 341. In the working mode of the first screw motor 34, the first motor body 342 drives the first screw 342 to move along a preset first direction or along a preset second direction opposite to the preset first direction. The first controllable telescopic body 23 is drivably connected to the first screw 342, so that when the first screw motor 34 drives the first screw 342 to move along the preset first direction, the first controllable telescopic body 23 is extended toward the outside of the mounting housing 10, or when the first screw motor 34 drives the first screw 342 to move along the preset second direction, the first controllable telescopic body 23 is retracted toward the inside of the mounting housing 10. Optionally, the telescopic control assembly 30 also includes a first transmission member 35 drivably connected between the first screw motor 34 and the first controllable telescopic body 23.

[0088] The second screw motor 36 includes a second motor body 361 and a second screw 362 connected to the second motor body 361. In the working mode of the second screw motor 36, the second motor body 361 drives the second screw 362 to move along a preset first direction or along a preset second direction opposite to the preset first direction. The second controllable telescopic body 24 is drivably connected to the second screw 362, so that when the second screw motor 36 drives the second screw 362 to move along the preset first direction, the second controllable telescopic body 24 is extended toward the outside of the mounting housing 10, or when the second screw motor 36 drives the second screw 362 to move along the preset second direction, the second controllable telescopic body 24 is retracted toward the inside of the mounting housing 10. Optionally, the telescopic control assembly 30 also includes a second transmission member 37 drivably connected between the second screw motor 36 and the second controllable telescopic body 24.

[0089] It's worth noting that in this modified embodiment, when the first screw motor 34 is in operation, the first screw 342 is simultaneously driven to rotate while moving in the predetermined first direction or the predetermined second direction, thereby driving the first controllable telescopic body 23 to rotate. When the second screw motor 36 is in operation, the second screw 362 is simultaneously driven to rotate while moving in the predetermined first direction or the predetermined second direction, thereby driving the second controllable telescopic body 26 to rotate. In this way, the first and second controllable telescopic bodies 23 and 24 provide a pressing and circular massage on the user's shoulders.

[0090] In particular, in the embodiment of the present application, the mounting shell 10 of the cervical vertebra traction nursing device has a special surface shape, so that when the cervical vertebra traction nursing device acts on the user's shoulder through the controllable telescopic body 20 (for example, the airbag 210) extending from the side of the mounting shell 10, the special surface shape of the mounting shell 10 and the reaction force of the user are used to cause the mounting shell 10 to flip in a direction away from the user, so that the user's neck cervical vertebra (i.e., cervical vertebra) is pulled and stretched, as shown in Figure 4. The movement mode of the cervical vertebra traction nursing device is switched from the telescopic extension of the controllable telescopic body 20 to the flipping of the mounting shell 10, and the mode of action of the cervical vertebra traction nursing device on the user is switched from pressing the user's shoulder to traction of the user's cervical vertebra. During the process of switching the controllable telescopic body 20 from the extended state to the retracted state, the mounting shell 10 is reset. During the process of switching the controllable telescopic body 20 from the retracted state to the extended state, the controllable telescopic body 20 presses the user's shoulder again, and the mounting shell 10 flips over again. The cervical vertebra traction nursing device repeatedly switches between different motion modes and different modes of action on the user. During the flipping process of the mounting shell 10 of the cervical vertebra traction nursing device, it performs a circular motion toward the surface of the user's cervical vertebra, so that it can better fit the physiological curve of the human body.

[0091] Specifically, in this embodiment of the present application, the bottom surface 106 of the mounting housing 10 forms a guide surface for the cervical traction nursing device, guiding the cervical traction nursing device to move in a predetermined direction. More specifically, the bottom surface 106 of the mounting housing 10 is non-planar, so that when the controllable telescopic body 20 extends toward a first side of the mounting housing 10, the mounting housing 10 flips toward a second side thereof, where the first side is opposite to the second side. More specifically, in the embodiment of the present application, the lower housing 11 has a central portion 110 and a first side portion 120 and a second side portion 130 located on either side of the central portion 110 in the width direction Y set by the mounting housing 10. The bottom surface of the central portion 110, i.e., the bottom central portion 107, protrudes downward from the bottom surface of the first side portion 120, i.e., the bottom first side portion 108, and the bottom surface of the second side portion 130, i.e., the bottom second side portion 109. The first side portion 120 and the second side portion 130 are respectively tilted upward from the central portion 110, i.e., the bottom first side portion 108 and the bottom second side portion 109 are respectively tilted from the bottom central portion 107. In a specific example of the present application, the bottom surface 10 of the mounting housing 10 is a curved surface.

[0092] The controllable telescopic body 20 is arranged on the first side portion 120. When the controllable telescopic body 20 extends from the first side portion 120 to the first side, the user applies a reaction force to the cervical traction care device from the first side portion 120 to the second side portion 130, that is, a reaction force from the first side to the second side. Since the bottom surface of the second side portion 130 is upwardly tilted relative to the middle portion 110, the bottom surface of the second side portion 130 is hollow, and the mounting shell 10 of the cervical traction care device is flipped toward the second side portion 130, that is, the second side, and the mounting shell 10 contacts the user's neck, thereby exerting a traction and stretching effect on the user's cervical vertebra.

[0093] That is, as the controllable telescopic body 20 expands and contracts, the cervical traction nursing device will present different movement modes and action modes at different stages. When the user rests his head on the cervical traction nursing device, the user's shoulder is located on the side of the cervical traction nursing device. In the first stage, the controllable telescopic body 20 extends to the first side of the mounting shell 10, and the controllable telescopic body 20 presses against the user's shoulder, playing the role of pressing the shoulder. While the controllable telescopic body 20 acts on the user's shoulder, the user's shoulder will generate a reaction force on the cervical traction nursing device, pushing the cervical traction nursing device to the second side opposite to the first side. When the reaction force of the user's shoulder on the cervical traction nursing device exceeds a certain value, for example, when it exceeds the friction between the cervical traction nursing device and the support supporting the cervical traction nursing device, the cervical traction nursing device is pushed and enters the second stage. In the second stage, since the bottom surface of the second side portion 130 of the cervical vertebra traction care device is hollow, the cervical vertebra traction care device flips toward the second side under the reaction force of the user. At the same time, the top surface of the cervical vertebra traction care device acts on the user's cervical vertebra, driving the user's cervical vertebra to move away from his shoulders, thereby traction and stretching the user's cervical vertebra.

[0094] It is worth mentioning that, due to the coordination of the telescopic direction of the controllable telescopic body 20 of the cervical traction nursing device and the surface shape of the mounting housing 10, the movement stroke of the controllable telescopic body 20 is relatively small, and the user's force is utilized during the flipping process of the controllable telescopic body 20. Therefore, the driving force requirements of the drive mechanism driving the controllable telescopic body 20, such as an air pump or a screw motor, are relatively low, and the driving mechanism also has relatively low requirements for a power source, such as a power supply. In this way, the number of drive mechanisms to choose from is increased, and a smaller drive mechanism can be selected.

[0095] In an embodiment of the present application, the cervical traction care device further includes a circuit board 40. The installation position of the circuit board 40 is not limited by the present application. In a specific example of the present application, the lower shell 11 includes a mounting base shell 111 and a receiving bottom shell 112 that interlock with each other. The receiving bottom shell 112 is formed below the mounting base shell 111. The lower shell 11 has a receiving cavity 101 formed between the mounting base shell 111 and the receiving bottom shell 112, and the circuit board 40 is received in the receiving cavity 101. The first air pump 31 and the second charging pump 32 are electrically connected to the circuit board 40. The circuit board 40 is arranged below the mounting base shell 111, and the first air pump 31 and the second charging pump 32 are arranged above the mounting base shell 111. The mounting base shell 111 has a wiring hole 103 for allowing electrical connection wires to pass through the mounting base shell 111 and connect between the circuit board 40 and the first air pump 31 and the second charging pump 32.

[0096] Optionally, the cervical traction nursing device further includes at least one electrical connection port 104 electrically connected to the circuit board 40, suitable for connecting a power connection line, a control connection line, or other types of electrical connection lines. The power connection line is an electrical connection line with a charging head, or an electrical connection line suitable for connecting to a power source, and the control connection line is an electrical connection line with a controller, or an electrical connection line suitable for connecting to a controller.

[0097] In one embodiment of the present application, the cervical traction nursing device further includes a flexible, deformable covering layer 50 covering the outside of the mounting housing 10, as shown in FIG6 , to provide greater comfort for the user. The material of the covering layer 50 is not limited by the present application; for example, the covering layer 50 can be made of flexible cloth.

[0098] In one embodiment of the present application, the cervical traction care device also includes a base pad 60 placed under the mounting shell 10. As shown in Figure 7, the bottom surface area of ​​the base pad 60 is relatively large, so that a relatively flat support surface can be provided, the support area of ​​the cervical traction care device can be expanded, and the height of the cervical traction care device can be adjusted.

[0099] Optionally, the base pad 60 is made of a flexible material to increase the user's comfort. For example, the base pad 60 can be made of felt, which is not only soft but also can generate greater friction with the support of the cervical vertebra traction nursing device.

[0100] Optionally, the cervical traction care device includes at least one support body 70 protruding from the surface of the base pad 60. The support body 70 extends between the base pad 60 and the mounting housing 10 to prevent the mounting housing 10 from significantly shifting during exercise. The support body 70 extends from the base pad 60 into the mounting housing 10, or from the mounting housing 10 into the base pad 60. The support body 70 is made of a flexible material and deforms with the mounting housing 10 when the mounting housing 10 is flipped.

[0101] In one embodiment of the present application, the base pad 60 of the cervical traction nursing device has at least one bendable portion 61 adjacent to the mounting housing 10, and the extending direction of the bendable portion 61 is consistent with the length direction of the mounting housing 10. In this way, when the mounting housing 10 is turned over, even if a human body presses on a portion of the base pad 60, the area of ​​the base pad 60 where the mounting housing 10 is mounted can bend relative to the area pressed by the human body, thereby preventing the area of ​​the base pad 60 pressed by the human body from affecting the turning of the mounting housing 10.

[0102] The bendable portion 61 is implemented as a fold. The base pad 60 has at least one area that is recessed inward from its surface. The fold is formed at the junction of the recessed area and the adjacent non-recessed area. It should be understood that the bendable portion 61 can also be implemented in other ways, such as a hinge or other mechanical structure.

[0103] In one embodiment of the present application, the cervical traction care device further includes a heat-conducting wire 62 disposed within the base pad 60, as shown in FIG7 . Optionally, multiple electrical connections between various components of the cervical traction care device are disposed within the base pad 60, forming the heat-conducting wire 62, thereby enabling the base pad 60 to be heated. Alternatively, a heat-conducting wire 62 specifically for heat conduction may be disposed within the base pad 60.

[0104] In the embodiment of the present application, optionally, the cervical traction care device further includes a handle 80 provided on the mounting shell 10 for easy carrying by the user.

[0105] Figures 8 to 16 are schematic diagrams of another preferred embodiment of the cervical vertebra traction care device of the present invention. The cervical vertebra traction care device of the present invention further includes a base 10A and a traction part 20A. The traction part 20A is arranged on the base 10A. Preferably, the traction part 20A is arranged in the middle of the base 10A. The traction part 20A has a limit part 21A. The limit part 21A is arranged in the middle of the traction part 20A. Preferably, the two ends of the traction part 20A are respectively recessed toward the middle to form the limit part. It is worth mentioning that when a user uses the cervical vertebra traction care device of the present invention, the user's neck contacts the traction part 20A. The traction part 20A tractions the user's neck in a rotational manner, thereby caring for the user's neck. Specifically, after the user's neck contacts the traction part 20A, the traction part 20A turns away from the user's shoulders to guide the user's cervical spine to stretch and thus provide traction. In a preferred embodiment of the present invention, the traction portion 20A further includes a heating device 22A and a far-infrared device 23A. The heating device 22A and the far-infrared device 23A are respectively disposed on the surface of the traction portion 22A to provide thermal care and far-infrared body care to the user. The traction portion 20A further includes a covering layer 24A. The covering layer 24A has a mounting opening 241A for nesting the far-infrared device 23A. The covering layer 24A is disposed on the surface of the traction portion 20A. Preferably, the mounting opening 241A is located in the middle of the covering layer 24A. Preferably, the covering layer 24A is made of a flexible material. In a preferred embodiment of the present invention, the covering layer 24A is made of silicone.

[0106] The base 10A further includes at least one shoulder massage device 11A, which is arranged on one side of the base 10A. Specifically, the shoulder massage device 11A is arranged on the side of the base facing the shoulder of the user. In a preferred embodiment of the present invention, the base 10A has two shoulder massage devices 11A. The two shoulder massage devices 11A are arranged on both sides of the traction part 20A, facing the shoulders of the user. When using the cervical vertebra traction care device of the present invention, the user adopts a lying position, and the user's neck contacts the limiting part 21 of the traction part 20A. The two shoulder massage devices 11A respectively face the shoulders of the user. The two shoulder massage devices 11A respectively extend toward the shoulders of the user. The two shoulder massage devices 11A respectively contact the two shoulders of the user. The two shoulder massage devices 11A continue to extend toward the two shoulders of the user to apply force to the two shoulders of the user. In this way, the cervical vertebra of the user is extended to provide traction care for the user. Furthermore, the neck of the user is in contact with the traction portion 20A. Preferably, the back of the user's head is in contact with the side of the traction portion 20A away from the user's shoulder. In this way, the user's neck is in a naturally extended state, which is conducive to maintaining the natural arch of the user's cervical vertebra. The traction portion 20A rotates in a direction away from the user's shoulder to traction the user's cervical vertebra in a rotational manner. The rotational traction not only utilizes the weight of the user's head itself, but also takes into account the natural arch of the cervical vertebra itself, thereby improving the care effect on the user's neck.

[0107] It is worth mentioning that the process of the two shoulder massage devices 11A applying force to the two shoulders can be used to adjust the position of the cervical vertebra traction nursing device of the present invention. Specifically, if the user is using the cervical vertebra traction nursing device of the present invention, the cervical vertebra traction nursing device of the present invention is set at an angle. The said inclined setting means that the distances between the two shoulder massage devices 11A and the two shoulders of the user are inconsistent. The distance between one of the shoulder massage devices 11A and one of the shoulders of the user is less than the distance between the other shoulder massage device 11A and the other shoulder of the user. When the two shoulder massage devices 11A apply pressure to the two shoulders of the user, the force applied by one of the shoulder massage devices 11A to one of the shoulder massage devices 11A is greater than the force applied by the other shoulder massage device 11A to the other shoulder of the user, then the reaction force applied to one of the shoulder massage devices 11A is greater, thereby pushing one of the shoulder massage devices 11A to move away from the shoulder of use. At the same time, the other shoulder massage device 11A moves closer to the shoulder of the user. In this way, the distances between the two shoulder massage devices 11A and both sides of the user's shoulders are adjusted respectively, so that the distances between the two shoulder massage devices 11A and both sides of the user's shoulders are consistent.

[0108] In a preferred embodiment of the present invention, the traction mode of the cervical vertebra traction nursing device of the present invention is horizontal traction in which the two shoulder massage devices 11A respectively apply forces to the two shoulders of the user to form a pushing mode, and rotational traction provided by the traction part 20A in a rotational manner. In a preferred embodiment of the present invention, the cervical vertebra traction nursing device of the present invention can adjust the position of the cervical vertebra traction nursing device of the present invention when performing horizontal traction by the two shoulder massage devices 11A respectively applying forces to the two shoulders of the user, so that the distances between the two shoulders of the user and the two shoulder massage devices 11A are equal, so that the neck of the user is at a preset position of the traction part 20A. When the neck of the user is at the preset position of the traction part 20A, the traction part 20A provides traction in a rotational manner, so that the cervical vertebra of the user obtains a better traction effect.

[0109] The shoulder massage device 11A further includes a pushing device 111A and a fixing device 112A. The pushing device 111A is fixed to the fixing device 112A. One end of the pushing device 111A is fixed to the fixing device 112A. The other end of the pushing device 111A moves in a direction away from the fixing device 112A. The other end of the pushing device 111A touches the shoulder of the user to apply force to the shoulder of the user. The shoulder massage device 11A further includes a protective shell 113A, which is arranged at the other end of the pushing device 111A. Specifically, the protective shell 113A has an extension surface 1131A. The extension surface 1131A extends as the pushing device 111A extends. Preferably, the extension surface 1131A is made of a flexible material. In a preferred embodiment of the present invention, the flexible material is silicone. It's worth noting that the extension surface 1131A further includes multiple folds 1132A. The shapes of these folds 1132A match the contours of the extension surface 1131A. As the extension surface 1131A extends away from the fixture 112A, the innermost folds 1132A extend the surrounding extension surface 1131A, driving the innermost folds 1132A to extend. By providing these folds, the extension length of the extension surface 1131A is increased.

[0110] In a preferred embodiment of the present invention, the extending device 111A is configured as at least one airbag 1111A. The fixing device 112A further has a accommodating chamber 1121A. The accommodating chamber 1121A accommodates the airbag 1111A. The fixing device 112A further has a communication port 1122A. The communication port 1122A is provided at the bottom of the fixing device 112A. The communication port 1122A is in communication with the accommodating chamber 1121A. Preferably, gas enters / exits the airbag 1111A through the communication port 1122A. When the gas enters the airbag 1111A, the airbag 1111A expands to push the extension surface 1131A to extend, thereby applying force to the user's shoulder. When the airbag 1111A is deflated, the airbag 1111A contracts, and the extension surface 1131A returns to its initial state. By controlling the speed of supplying and deflating air to the airbag 1111A, a massage rhythm is formed. The protective shell 113A further includes a guide wall 1133A. The guide wall 1132A is perpendicular to the extension surface 1131A. The protective shell 113A can be embedded in the accommodating cavity 1121A. When the airbag 1111A expands, it expands along the guide wall toward the extension surface 1131A. In this way, the expansion direction of the airbag 1111A is limited, thereby improving the extension efficiency of the extension surface 1131A. It will be appreciated by those skilled in the art that the pushing device 111A can be implemented as a mechanical structure, such as a telescopic rod.

[0111] The shoulder massage device 11A further includes a massage device 114A. The massage device 114A is disposed between the extension surface 1131A and the pushing device 111A. Preferably, the massage device 114A is fixed to the pushing device 111A. The massage device 114A extends as the pushing device 111A extends, and contracts as the pushing device 111A contracts. In a preferred embodiment of the present invention, the massage device 114A is implemented as a vibration motor 1141A. The vibration motor 1141A is disposed between the extension surface 1131A and the airbag 1111A. When the airbag 1141A expands, the vibration motor 1141A is pushed toward the user's shoulders to provide massage to the user's shoulders.

[0112] The base 10A is further provided with two massage device accommodating chambers 12A. The two massage device accommodating chambers 12A are respectively arranged on both sides of the traction portion 20A.

The traction portion 20A is rotatably arranged in the traction portion accommodating chamber 13A. The traction portion 20A rotates in the traction portion accommodating chamber 13A toward the side away from the shoulder massage device 11A. The traction portion accommodating chamber 13A is arranged between the two massage device accommodating chambers 12A. A curved surface is provided on the side of the base 10A where the two shoulder massage devices 11A are installed to adapt to the shoulders of the user. The base 10A further includes a bottom cover 14A and a mounting frame 15A. The bottom cover 14A is mounted to the bottom of the mounting frame 15A to form a mounting cavity 1551A within the mounting frame 15A.

The control circuit 161A includes multiple solenoid valves 162A for controlling the gas supply to the airbag 1111A and the driving airbag 252A. The first mounting bracket 16A further includes a first gas supply port 163A. The first gas supply port 163A corresponds to one of the communication ports 1122A to supply gas thereto. The first mounting bracket 16A further includes a first fixing bracket 164A. The first fixing bracket 164A is used to fix one of the shoulder massage devices 11A. The second mounting bracket 17A further has a second gas supply port 174A.
