Description

TECHNICAL FIELD

[0001] The present application relates to a cervical traction device, in particular, to a cervical traction device with three independent air bags inside. BACKGROUND

[0002] The upper side of the cervical vertebrae can be connected to the skull, and the lower side of the cervical vertebrae can be connected to the thoracic cavity, which is self-evident in importance. However, modern people are increasingly suffering from cervical spondylosis (or cervical syndrome, cervical joint disease), and the main causes are bad living habits (such as long-time low head operation of mobile phones, game consoles or computers, incorrect standing or sitting posture), or work requirements (such as driving), causing the neck to maintain a fixed posture for a long time, or excessive psychological stress, etc. The aforementioned situations will cause the user's neck muscles to become more and more tense over time, or even cervical joint deformity or intervertebral disc degeneration or protrusion (i.e., excessive compression), which can easily cause nerve impingement, arthritis, joint pain, premature intervertebral disc degeneration or thinning, and finally develop symptoms such as arm pain or numbness, chronic headache, chronic neck and shoulder pain, etc.

[0003] Most of the cervical spondylosis, especially chronic neck and shoulder dysfunction, is caused by tight neck or upper shoulder muscles, excessive compression of cervical joints and intervertebral discs, etc. The aforementioned situations can easily cause nerve irritation and impingement, resulting in patients suffering from neck and shoulder pain almost every day, especially the whole day's work, which can exacerbate the pain, causing patients to still have difficulty relaxing and falling asleep at night. In addition, the general commercially available pillows are almost useless for patients with cervical spondylosis, but can cause more severe neck and shoulder pain, headache, and / or arm pain or numbness after the patient rests on the aforementioned commercially available pillows for a long time. Generally speaking, for patients with chronic neck and shoulder dysfunction, doctors usually recommend cervical traction therapy to help reduce the pressure between multiple intervertebral discs and relax the neck and shoulder muscles, as well as reduce the pressure and irritation of the paraspinal nerves, thereby relieving the pain in the neck and shoulder. Among them, the joint is pulled apart by external force, the muscles connected between them are relaxed, which is called traction. Traction not only affects the joint, but also relaxes tight muscles, tendons and / or ligaments, and can reduce the pressure and irritation of the paraspinal nerves, so it can eliminate pain, numbness and improve joint mobility.

[0004] However, in reality, most patients cannot afford the time or money required for conventional treatment, resulting in the fact that these patients do not actually receive treatment and unnecessarily suffer. In addition, cervical traction includes manual traction and mechanical traction, but both require trained medical personnel, and for patients receiving conventional treatment, many cannot obtain the correct medical personnel to provide them with the appropriate treatment they need, resulting in the pain of these patients not being effectively alleviated. In the case of not receiving treatment or treatment failure, some patients will try to take painkillers, use ointments or tapes, etc., but the effect of the aforementioned drugs is limited, and long-term use of drugs can have serious side effects.

[0005] In addition, the existing cervical traction device also has other problems. Traditionally, the existing cervical traction device usually uses a head / neck safety belt to pull the head away from the neck longitudinally to perform traction on the cervical vertebrae, and a counterweight or electric machine is required in a medical clinic to drive the aforementioned existing cervical traction device to complete the traction operation. In addition, the existing cervical traction device is bulky and uncomfortable to use, and the use is difficult, often requiring the assistance of professional medical personnel. Since the existing cervical traction device cannot be used as a pillow, the user cannot use the existing cervical traction device when lying down or sleeping.

[0006] In summary, many people suffer from chronic headaches, chronic neck and shoulder dysfunction, and other pain caused by tight neck muscles, excessive pressure on cervical joints, intervertebral disc degeneration or protrusion, nerve compression or inflammation, etc., which worsens their health and quality of life without a good improvement method. Therefore, how to effectively solve the aforementioned problems so that people can independently complete cervical traction without spending high time and / or money has become an important issue of the present application. SUMMARY

[0007] In view of the aforementioned shortcomings of the conventional cervical traction device, the inventor has finally developed an inflatable cervical traction device after long-term research and experiments, hoping to provide users with better user experience and effectively solve the existing problems.

[0045] The following embodiments will further illustrate the related technical content of the present application, but the disclosed content is not intended to limit the scope of protection of the present application.

[0046] The present application is an inflatable cervical traction device. For the convenience of description, unless the context clearly indicates otherwise, the following embodiments take Figure 1 the lower right of Figure 1 the upper left of Figure 1 the upper side of Figure 1 the lower side of Figure 1 the upper right of Figure 1 the lower left of However, the present application is not limited thereto. In an embodiment, the cervical traction device S is divided from front to back into a support portion S1 and a bearing portion S2, wherein the top surfaces of both the support portion S1 and the bearing portion S2 are designed to be ergonomically suitable for the natural curvature of the cervical spine, so that the top surface height of the bearing portion S2 is lower than that of the support portion S1.

[0047] Please refer back to Figure 1 and Figure 2 shown, when the user lies on the cervical traction device S in a supine position, the bearing portion S2 can bear the occipital position of the user's head (such as Figure 2The support portion S1 can be positioned relative to the user's neck and cooperate with the cervical lordosis to provide corresponding support force to help the user restore the cervical vertebrae to the correct alignment and posture. In addition, since the cervical traction device S itself has elasticity, when the user rests his head on the cervical traction device S, the cervical traction device S will deform so that its top surface can conform to the surface profile of the user's head and neck to achieve the desired load bearing and support effect.

[0048] Please refer to Figure 3 and Figure 4 In this embodiment, the cervical traction device S includes a pillow body 1 and a pillow cover 2. The pillow cover 2 is provided with a fitting space 20 that can cover the pillow body 1 so that the pillow body 1 is positioned in the fitting space 20. The configuration of the pillow cover 2 matches the pillow body 1, so that when the pillow body 1 is placed in the pillow cover 2, the structure of the pillow body 1 is still clearly shown. Therefore, in the following description of the components of the pillow body 1, the positions of the components are still indicated. Figure 1

[0049] Please also refer to Figure 3 and Figure 4 In this embodiment, the pillow body 1 can be made of foamed material and / or other elastic body and / or filling material, and is provided with the support portion S1 and the load bearing portion S2. The central position of the support portion S1 is provided with a neck support body 11, and the top surface of the neck support body 11 can support the user's neck (as shown in Figure 2 In order to better achieve the effect of supporting the neck, the front side of the neck support body 11 further extends forward to completely or nearly completely support the user's neck position. When the neck support body 11 abuts and supports the user's neck, the user's head naturally tilts backward, which helps to more stably fix the user's head to the load bearing portion S2.

[0050] Please also refer to Figure 3 and Figure 4 In this embodiment, one of the shoulder abutting bodies 12 is located on the support portion S1 and is positioned closer to the right side of the support portion S1 than to the left side of the support portion S1, and the other shoulder abutting body 12 is located on the support portion S1 and is positioned closer to the left side of the support portion S1 than to the right side of the support portion S1. The two shoulder abutting bodies 12 can respectively extend from the front side of the support portion S1. When the user's head rests on the cervical traction device S, the front sides of the two shoulder abutting bodies 12 can abut the user's shoulders (as shown in​Figure 5 as shown).

[0051] Please refer to Figure 3 and Figure 4 , the bottom surface of the neck support body 11 is concavely provided with a first recess 110, and a first air bag 13 is accommodated in the first recess 110, wherein the first air bag 13 can expand or contract along a first axis (such as the Z-axis in the up-down direction of Figure 3 , when the first air bag 13 expands or contracts along the first axis, it will cause the top surface of the neck support body 11 to displace along the first axis, for example, upwards or downwards. In some embodiments, when the first air bag 13 is inflated to a first maximum expansion state, the maximum length of the first axis direction is 75-85 mm, but the present application is not limited thereto. It is particularly pointed out here that as long as the first air bag 13 is accommodated in the first recess 110, its expansion or contraction is sufficient to cause the top surface of the neck support body 11 to displace, then the position of the aforementioned first recess 110 is the bottom surface of the neck support body 11.

[0052] Please refer to Figure 3 and Figure 4 , the bottom surface of the two shoulder abutting bodies 12 is respectively concavely provided with a second recess 120, and two second air bags 14 are respectively accommodated in the corresponding second recess 120, wherein the two second air bags 14 can expand or contract along a second axis (such as the X-axis in the front-back direction of Figure 3 , and the second axis is substantially perpendicular to the first axis, it is particularly pointed out here that the aforementioned "substantially perpendicular" includes "perpendicular (the intersection angle between the first axis and the second axis is 90 degrees)" and "close to perpendicular". When the two second air bags 14 respectively expand or contract along the second axis, it will cause the front side of the two shoulder abutting bodies 12 to displace along the second axis, for example, forwards or backwards. In some embodiments, when the second air bag is inflated to a second maximum expansion state, the maximum length of the second axis direction is 55-65 mm, but the present application is not limited thereto. It is particularly pointed out here that as long as the two second air bags 14 are respectively accommodated in the corresponding second recess 120, their expansion or contraction is sufficient to cause the front side of the shoulder abutting body 12 to displace, then the position of the aforementioned second recess 120 is the bottom surface of the shoulder abutting body 12.

[0053] Please refer to Figure 3 and Figure 4As shown, an inflating device 15 is connected to the first air bag 13 and the second air bags 14 respectively, and when the inflating device 15 is operated, it can inflate or deflate the first air bag 13 and the second air bags 14 to change the expansion or contraction size of the first air bag 13 and the second air bags 14. In this embodiment, the inflating device 15 includes an inflating part 151, a plurality of pipe bodies 152, a first air valve 153 and a second air valve 154, wherein the inflating part 151 is a hand-pressed inflating pump (but not limited thereto, in other embodiments, an electric inflating pump can also be used), and the pipe bodies 152 can pass through the pillowcase 2 and the pillow body 1 to communicate the first air bag 13 and the second air bags 14 respectively, so that the inflating part 151 can inflate or deflate the first / second air bags 13, 14 through the pipe bodies 152. In addition, the first air valve 153 is assembled to one of the pipe bodies 152, and the pipe body 152 is used to communicate the first air bag 13, and the second air valve 154 is assembled to another pipe body 152, and the pipe body 152 is used to communicate the second air bags 14.

[0054] As shown in Figure 3 and Figure 4 , when the first air valve 153 is opened, the inflating part 151 can inflate or deflate the first air bag 13, and vice versa, when the first air valve 153 is closed, the inflating part 151 cannot inflate or deflate the first air bag 13; similarly, when the second air valve 154 is opened, the inflating part 151 can inflate or deflate the second air bags 14 at the same time, and vice versa, when the second air valve 154 is closed, the inflating part 151 cannot inflate or deflate the second air bags 14. Although in this embodiment, only one second air valve 154 is provided to adjust the expansion or contraction degree of the second air bags 14 at the same time, in other embodiments of the present application, two second air valves 154 can be provided to adjust the expansion or contraction degree of any one of the second air bags 14 individually. In addition, in actual use, the user can open the first air valve 153 and the second air valve 154 at the same time to make the inflating part 151 inflate the first air bag 13 and the second air bags 14 at the same time, but if the inflating efficiency of the first air bag 13 is to be improved, only the first air valve 153 can be opened and the second air valve 154 can be closed. Similarly, if the inflating efficiency of the second air bag 14 is to be improved, only the second air valve 154 can be opened and the first air valve 153 can be closed.

[0055] As shown in Figure 1 , Figure 2 and Figure 6As shown, when the user's head is rested on the cervical traction device S, the first air bag 13 can be inflated by the inflation part 151, and at this time, the first air bag 13 will gradually expand, so that the top surface of the neck support body 11 gradually moves upward, and in turn pushes the user's neck upward, so that the user's cervical vertebrae can restore to the natural lordotic curvature, and present the expected arch shape. When the top surface of the neck support body 11 does not move due to the expansion of the first air bag 13, the top surface of the neck support body 11, or more precisely, the position of the top surface corresponding to the highest point of the first air bag 13 along the Z-axis direction as shown, has a top surface height relative to the bottom surface of the neck support body 11, which can be defined as the first height N1. Figure 3 When the first air bag 13 expands to the first maximum expansion state and the top surface of the neck support body 11 moves to the corresponding position, the top surface of the neck support body 11, or more precisely, the position of the top surface corresponding to the highest point of the first air bag 13 along the Z-axis direction as shown, has a top surface height relative to the bottom surface of the neck support body 11, which can be defined as the second height N2. Figure 3 In some embodiments, the ratio of the first height N1 to the second height N2 is about 1:1.10-1.70, and in some embodiments, the ratio can be about 1:1.26-1.46. In this way, by the design of the first air bag 13, when the user lies on the cervical traction device S, the height and firmness of the cervical traction device S corresponding to the user's neck region can be adjusted, so as to help the user's neck to maintain in the appropriate position and good posture, and the user's cervical vertebrae can be aligned and centered.

[0056] As shown in Figure 5 and Figure 7 When the two second air bags 14 are inflated by the inflation part 151, the two second air bags 14 will gradually expand, so that the front side of the two shoulder abutting bodies 12 gradually moves forward, and in turn pushes the user's shoulders forward (i.e., toward the user's feet). Please also refer to Figure 7As shown, the length of the shoulder support body 12 is the distance from its front surface to the rear surface of the pillow body 1. When the front surface of the shoulder support body 12 is not displaced by the expansion of the corresponding second airbag 14, the length from the front surface of the shoulder support body 12 to the rear surface of the pillow body 1 can be defined as a first length M1. When the front surface of the shoulder support body 12 is displaced to a corresponding position due to the expansion of the corresponding second airbag 14 to the second maximum expansion state, the length from the front surface of the shoulder support body 12 to the rear surface of the pillow body 1 can be defined as a second length M2. In some embodiments, the ratio of the first length M1 of the shoulder support body 12 to the second length M2 after displacement is approximately 1:1.01 to 1.15. In some embodiments, the ratio can be approximately 1:1.04 to 1.12.

[0057] See also Figure 8 As shown, when the first airbag 13 is inflated, the top surface of the neck support body 11 is displaced along the first axis (e.g., upward), and when the second airbag 14 is inflated, the front side of each shoulder support body 12 is displaced along the second axis (e.g., forward). When viewed from the side, the position of the user's head and neck resting on the cervical traction device S is at the hypotenuse of the two displacement directions of the cervical traction device S (along the first and second axes, e.g., upward and forward). Figure 3 and Figure 12 As shown, when the top surface of the neck support body 11 is not displaced by the expansion of the first airbag 13, and the front surface of the shoulder abutment body 12 is not displaced by the expansion of the corresponding second airbag 14, the top surface of the neck support body 11 corresponds to the position of the highest point of the first airbag 13 along the Z axis at a position between the first axis and the second axis (for example, Figure 3 The distance between the projection point on the plane defined by the Z-axis and the X-axis shown in the figure and the projection point of the center point of the front surface of the shoulder support body 12 on the plane can be defined as a first distance T1; when the top surface of the neck support body 11 is displaced to the corresponding position due to the expansion of the first airbag 13 to the first maximum expansion state, and the front surface of the shoulder support body 12 is displaced to the corresponding position due to the expansion of the corresponding second airbag 14 to the second maximum expansion state, the distance between the above-mentioned two projection points can be defined as a second distance T2; in addition, in some embodiments, the ratio of the first distance T1 to the second distance T2 is approximately in the range of 1:1.30 to 1.95, and in some embodiments, the ratio can be approximately in the range of 1:1.55 to 1.75.

[0058] As described above, when a user's head and neck rest on the cervical traction device S, the user's head is sunken into the support portion S2 and the neck is supported by the neck support body 11. Therefore, the head and neck can serve as an anchor and be positioned on the cervical traction device S. Subsequently, when the two second airbags 14 are inflated, they push the user's shoulders away from the head, generating a pulling force on the user's neck and shoulder muscles. This, in turn, increases the intervertebral disc space between the multiple vertebrae of the cervical spine, reducing pressure within the intervertebral discs and increasing the diameter of the neural foramina to improve nerve compression symptoms, thereby avoiding or alleviating symptoms such as neck and shoulder pain, arm cramps, or numbness. The aforementioned mechanism is used to stretch the user's neck and upper shoulder muscles and provide traction therapy for the cervical spine, relieving tense muscles and reducing pressure on the intervertebral discs in the cervical spine. This can alleviate or eliminate symptoms such as spinal nerve pressure, upper shoulder pain, arm cramps, or numbness that cause neck pain. In this way, the user can adjust the expansion or contraction size of the first airbag 13 and the second airbag 14 by operating the inflation device 15, thereby changing the force applied by the neck support body 11 and the shoulder support body 12 to the user's neck / shoulder, so as to achieve the effect of cervical traction independently.

[0059] See also Figure 9 to Figure 11 As shown, in some embodiments, the inflation device 15 includes a plurality of inflation sections 151. The plurality of inflation sections 151 can be in the form of a hand-operated inflation pump. One of the inflation sections 151 can be connected to at least one tube 152, and the first airbag 13 can be connected through the at least one tube 152 corresponding to the inflation section 151. The first air valve 153 can be assembled to the at least one tube 152 corresponding to the inflation section 151 corresponding to and connected to the first airbag 13. Another inflation section 151 can be connected to at least another tube 152, and the two second airbags 14 can be connected through the at least another tube 152 corresponding to the another inflation section 151. The second air valve 154 can be assembled to the at least one tube 152 corresponding to the inflation section 151 corresponding to and connected to the second airbag 14.

[0060] It is particularly mentioned here that this application is not limited to Figure 1 The style, in Figure 1 In the embodiment, when the second airbag 14 is not inflated, its shoulder portion extends forward against the front surface of the body 12 to form a convex shape. Figure 12 to Figure 14 As shown, in other embodiments of the present application, the two shoulder abutment bodies 12 of the cervical traction device S are disposed on the left and right sides of the neck support body 11, and they will not be as Figure 1Generally, when the second airbag 14 is not inflated, it extends from the front surface of the support portion S1 to form a protrusion. When the second airbag 14 in the cervical traction device S is inflated and begins to expand, the two shoulders will be pressed against the body 12 as if Figure 1 Generally, the support portion S1 gradually protrudes outwards, thereby abutting against and pushing the user's shoulders.

[0061] Furthermore, please refer to Figure 13 As shown, in other embodiments of the present application, an electric inflation device 18 is provided on one side of the cervical traction device S, wherein the electric inflation device 18 adopts an electric inflation pump, and its tube body, first air valve and second air valve are all hidden in the cervical traction device S and will not be exposed to the outside to maintain the beauty of the product. In this way, the user can easily inflate or deflate the first airbag 13 and the second airbag 14 by directly operating the control panel of the inflation device 18.

[0062] When using the cervical traction device S, the user can not only utilize the inflation effect of the first airbag 13 and the second airbag 14 to stretch the neck and shoulder muscles to achieve the effect of cervical traction therapy, but also can use physical therapy methods such as electrotherapy and / or heat therapy to relax the tense muscles of the neck and shoulders, improve local blood circulation, and relieve pain in the head, neck and shoulders, as well as improve symptoms such as arm cramps or numbness. Figure 1 to Figure 5 As shown, the cervical traction device S is further provided with a plurality of physical therapy parts 21, and the physical therapy parts 21 are substantially located at positions corresponding to the neck support body 11. When the user's head rests on the cervical traction device S, the physical therapy parts 21 can be attached to the user's neck, and the physical therapy parts 21 can be combined with a physical therapy device 17 (such as Figure 14As shown) are electrically connected to receive electricity from the physical therapy device 17 (such as a low-frequency therapy device (also known as a transcutaneous electrical nerve stimulator, Transcutaneous electrical nerve stimulator, abbreviated as TENS), an electronic muscle stimulation (EMS) device), so that the physical therapy parts 21 can exert electrotherapy and / or thermal therapy effects. The physical therapy device 17 can be provided with at least one button for the user to operate the button to turn on, turn off or output electric pulses of different sizes and / or frequencies. Alternatively, the physical therapy device 17 can also receive wireless signals (such as Bluetooth, WiFi, etc.) so that the user can operate a wireless controller to turn on, turn off or output different amounts of electricity. In this embodiment, at least one of the physical therapy parts 21 and the physical therapy device 17 is arranged on the pillowcase 2 and can be removed from the pillowcase 2 so that the user can wash the pillowcase 2 without causing damage to the physical therapy parts 21 and the physical therapy device 17. However, in other embodiments of the present application, at least one of the physical therapy parts 21 and the physical therapy device 17 can also be arranged on the pillow body 1, and the pillowcase 2 can be perforated so that the physical therapy device 17 is exposed. However, the present application is not limited to this.

[0063] Furthermore, see Figure 15 to Figure 24 As shown, the physical therapy device 17 can be positioned on the cervical traction device S through a positioning member H. The positioning member H has a release / locking mechanism L. The release / locking mechanism L can fix the physical therapy device 17 on the positioning member H and can also release the physical therapy device 17 from the positioning member H (that is, the physical therapy device 17 can be detached from the positioning member H). In this way, when the user needs to wash the cervical traction device S (such as washing the pillowcase 2), the physical therapy device 17 can be removed from the positioning member H to avoid damage to the physical therapy device 17. In some embodiments, the release / locking mechanism L can be a harness with a lock. In addition, the positioning member H can be provided with a conductive portion to transfer the electricity generated by the physical therapy device 17 and / or the portable battery unit thereon to each of the physical therapy parts 21, so that each of the physical therapy parts 21 can provide electrotherapy and / or thermal therapy.

[0064] The various forms of the positioning member H are described below. Figure 15 to Figure 18As shown, in the first embodiment, the positioning member H includes a base plate H11, a positioning body H12, an inner plate H13, a plurality of conductive portions H14, and a plurality of wire connecting portions H15. The rear side of the base plate H11 is provided with a magic tape to be attached to the cervical traction device S (e.g., the pillow cover 2 or the pillow body 1). The positioning body H12 is made of at least an elastic material, and the rear side thereof is fixed to the base plate H11. The front side of the positioning body H12 is provided with a receiving groove H120. The inner plate H13 is located at the bottom of the receiving groove H120. The inner diameter of the receiving groove H120 is slightly smaller than the outer diameter of the physical therapy device 17 (e.g., the inner diameter is about 0.1% to 5% smaller than the outer diameter of the physical therapy device 17). The groove wall of the receiving groove H120 forms the release / locking mechanism L. When the physical therapy device 17 is placed into the receiving groove H120, the groove wall (release / locking mechanism L) of the receiving groove H120 slightly expands due to its elasticity, and tightly covers the outer periphery of the physical therapy device 17, so that the physical therapy device 17 is positioned on the positioning body H12. When the physical therapy device 17 is pulled outward, as long as the pulling force is greater than the fixing force (i.e., friction or clamping force) of the groove wall (release / locking mechanism L) of the receiving groove H120 on the physical therapy device 17, the physical therapy device 17 can be separated from the release / locking mechanism L.

[0065] As mentioned above, please refer to Figure 15 to Figure 18 As shown, the conductive portions H14 extend into the receiving groove H120, and sequentially pass through the inner plate H13, the bottom of the receiving groove H120, and the base plate H11. The wire connecting portions H15 are located between the positioning body H12 and the base plate H11, and are electrically connected to the corresponding conductive portions H14. Each wire connecting portion H15 can be electrically connected to an external wire. The rear side of the physical therapy device 17 is provided with a plurality of power transmission portions 171. When the physical therapy device 17 is placed into the receiving groove H120, each power transmission portion 171 is electrically connected to the corresponding conductive portion H14, so that the current (current pulse signal) output by the physical therapy device 17 is sequentially transmitted to the wire connecting portion H15 through the power transmission portion 171 and the conductive portion H14. However, in other embodiments of the present application, the conductive portion H14 and the wire connecting portion H15 can be integrated into a single component (equivalent to omitting the wire connecting portion H15), so that each conductive portion H14 can be electrically connected to an external wire.

[0066] In addition to the above-mentioned release / locking mechanism L, please refer to Figure 19 to Figure 21As shown, in the second embodiment, the positioning member H includes a substrate H21, a positioning body H22, and a plurality of conductive portions H24. The substrate H21 and the positioning body H22 can be assembled into one body. The conductive portions H24 are fixed to the positioning body H22. The front side of the positioning body H22 protrudes at least one protruding rail H211, which is the release / locking mechanism L of the second embodiment. The rear side of the physical therapy device 17 is provided with at least one recess 173. The width and / or length of each recess 173 is slightly smaller than the corresponding width and / or length of each protruding rail H211 (for example, 0.1% to 5% smaller than the width of each protruding rail H211). When the physical therapy device 17 is assembled to the positioning member H, each protruding rail H211 can be embedded in the corresponding recess 173. At the same time, the power transmission portion 171 on the rear side of the physical therapy device 17 is electrically connected to the corresponding conductive portion H24. When the physical therapy device 17 is pulled outward, as long as the pulling force is greater than the clamping force between the recess 173 and the protruding rail H211, the physical therapy device 17 can be separated from the release / locking mechanism L.

[0067] As shown in FIG. 1, the cervical traction device S includes a main body S1, a plurality of physical therapy devices 17, and a plurality of physical therapy portions 21. The main body S1 is provided with a plurality of physical therapy devices 17. The physical therapy devices 17 are electrically connected to the physical therapy portions 21. The physical therapy portions 21 are arranged on the neck and shoulders of the user. The cervical traction device S can provide physical therapy services to the user. Figure 22 to Figure 24 As shown, in the third embodiment, the positioning member H includes at least one substrate H31, a positioning body H32, and a plurality of conductive portions H34. The front side of each substrate H31 can be attached to the rear side of the positioning body H32. The rear side of each substrate H31 can be attached to a connecting plate H30 (for example, at least one magic tape). The positioning body H32, the substrate H31, and the connecting plate H30 can be assembled into one body through a plurality of fasteners H36. The front side of the positioning body H32 is provided with a receiving groove H320. The physical therapy device 17 can be placed in the receiving groove H320. The groove wall of the receiving groove H320 forms the release / locking mechanism L. When the positioning body H32 and the substrate H31 are assembled into one body, the unshielded part of the substrate H31 by the positioning body H32 is provided with at least one fixing component H37 (for example, a button). The fixing component H37 can be buckled with another fixing component on the cervical traction device S, so that the positioning member H can be more stably positioned on the cervical traction device S.

[0068] In other words, as shown in FIG. 1, the cervical traction device S includes a main body S1, a plurality of physical therapy devices 17, and a plurality of physical therapy portions 21. The main body S1 is provided with a plurality of physical therapy devices 17. The physical therapy devices 17 are electrically connected to the physical therapy portions 21. The physical therapy portions 21 are arranged on the neck and shoulders of the user. The cervical traction device S can provide physical therapy services to the user. Figure 15 to Figure 24 As shown, the positioning member H can be provided with various conductive and connecting members described above, so that the physical therapy device 17 and each physical therapy portion 21 and / or the electrode on the neck and shoulders can be electrically connected. In this way, by using the design of the cervical traction device S for fixing the physical therapy device 17 and providing physical therapy services, the cervical traction device S can use TENS, EMS, or other electrotherapy / thermotherapy equipment to treat the neck and shoulders of the user, so as to relieve the user's headache, neck pain, shoulder pain, and arm numbness pain, etc.

[0069] As mentioned above, when the user needs to clean the cervical traction device S, the release / lock mechanism L can be unlocked first to detach the therapeutic device 17 from the positioning member H before the cervical traction device S is washed by water, so as to prevent the water sensitive electronics inside the therapeutic device 17 from being damaged by water. Furthermore, the therapeutic device 17 can be directly arranged on the cervical traction device S (i.e. not indirectly arranged on the cervical traction device S via the positioning member H), and electrically connected to the therapeutic portions 21 so as to transmit electric current to the therapeutic portions 21. Please refer to Figure 25A As shown in some embodiments, the therapeutic portion 21 can be provided with an electrotherapy unit EU. The electrotherapy unit EU can be provided with a conductive layer 211, and optionally a film layer 212 and a connecting layer 213, wherein the conductive layer 211 can be made of conductive fiber, conductive film, conductive cloth, aluminum foil or mixture thereof, or other conductive material, and one side of the conductive layer 211 is provided with the optional film layer 212 (e.g. conductive gel), and the other side of the conductive layer 211 is provided with the connecting layer 213. The conductive layer 211 can be electrically connected to a metal member 22, and the metal member 22 can be electrically connected to an electric wire 215, which in this embodiment is wound around the metal member 22 via an insulating tape 217. In addition, the connecting layer 213 (e.g. adhesive) can be fixed to the pillowcase 2, and in other embodiments, the connecting layer 213 can be fixed to the pillow body 1. In this way, when the user uses the therapeutic portion 21, the conductive layer 211 or the film layer 212 (if the therapeutic portion 21 is provided with the film layer 212) can be in contact with the skin surface of the human body, and after the electric wire 215 is electrically connected to the therapeutic device 17 (e.g. a TENS or EMS device), the therapeutic portion 21 can receive electric power from the therapeutic device 17, so as to output electric stimulation to the neck of the user, so as to achieve electrotherapy effect. However, the therapeutic portion 21 is not limited to the above structure, and in other embodiments of the present application, the film layer 212 can be omitted, so that the conductive layer 211 directly contacts the skin; the connecting layer 213 can be cloth (e.g. non-woven fabric, cotton cloth), and can be connected to conductive sheet (e.g. aluminum foil), so as to be better combined to the pillow body 1 or the pillowcase 2.

[0070] Please refer to Figure 25BAs shown, in some embodiments, the physical therapy portion 21 can be provided with a thermal therapy unit HU. The thermal therapy unit HU can be composed of two insulating layers 218 (e.g., non-woven fabric) and a heating layer 219. The heating layer 219 can be made of a metal material (e.g., iron-chromium-aluminum alloy wire, nickel-chromium alloy wire), graphene, carbon fiber, or other electrothermal materials to generate heat when an electric current passes through it. The heating layer 219 is located between the two insulating layers 218, and the outer surface of one insulating layer 218 can be fixed to the corresponding pillowcase 2. Alternatively, in other embodiments, the insulating layer 218 can be fixed to the pillow body 1. The heating layer 219 can be electrically connected to the metal part 22 to receive electricity from the physical therapy device 17 through an electric wire 215, thereby causing the physical therapy part 21 to generate heat and dissipate it through each of the insulating layers 218 to heat the user's neck, thereby relaxing the blood vessels and promoting local blood circulation to increase the metabolic rate, thereby accelerating the discharge of inflammatory substances from the human body to improve the self-repair ability of muscle tissue. At the same time, hot compress (thermal therapy) can also increase the elasticity of the human body's soft tissue to reduce muscle spasms, thereby alleviating the pain suffered by the human body and relaxing the mood. However, in other embodiments of the present application, the physical therapy part 21 can also omit the insulating layer 218, and the heating layer 219 can directly contact the skin. Please refer to Figure 25C As shown, in some embodiments, the physical therapy part 21 can be an electrotherapy / thermal therapy hybrid unit, which can be formed by superimposing the aforementioned electrotherapy unit EU and thermal therapy unit HU. For example, a heating layer 219 is arranged between two insulating layers 218, and the outer surface of one of the insulating layers 218 can be covered with a conductive layer 211 (such as conductive fiber). The heating layer 219 and the conductive layer 211 can receive electricity from the physical therapy device 17 through the same or different metal parts 22, wherein the conductive layer 211 can output electrical stimulation to the user's neck, and the heating layer 219 can generate heat, and the heat is transmitted through the insulating layer 218 and the conductive layer 211 to heat the user's neck.

[0071] However, the present application is not limited thereto. As long as the structure of the physical therapy part can achieve the results and effects of physical therapy, the aforementioned structures fall within the scope of the physical therapy part 21 defined in the present application.

[0072] Finally, please refer to Figure 4As shown, a bottom plate 16 is assembled to the bottom surface of the pillow body 1 to cover the first recess 110 and the second recess 120, and to prevent the first air bag 13, the second air bag 14 and the pipe bodies 152 from being separated from the pillow body 1. However, in other embodiments of the present application, the bottom plate 16 can be omitted, and the first air bag 13, the second air bag 14 and the pipe bodies 152 can be clamped by the elasticity of the pillow body 1, or clamped by other clamping structures.

[0073] The above description is only the preferred and feasible embodiments of the present application, and does not limit the protection scope of the claims of the present application. Any equivalent changes made by those skilled in the art based on the disclosed technical contents of the present application without creative labor should be included in the protection scope of the claims of the present application.
