Description

Traction device for traction of the subject's spine and method for traction of the subject's spine

[0001] The present invention relates to a traction device for traction of a subject's spine and a method for traction of a subject's spine, and more particularly, to a traction device and a traction method that simultaneously include a function of massaging a subject's spine and a function of traction of a subject's spine.

[0002] In general, back pain, a symptom of spinal pain, is a fateful condition that arises as humans, unlike other animals, evolved to be bipedal. Approximately 80% of the entire population, regardless of gender or age, suffers from back pain. Furthermore, in addition to the aforementioned back pain, the recent proliferation of smartphones has led many people to bend their heads forward for long periods of time, leading to a common cervical pain condition known as "straight neck" (or "turtle neck"). This spinal condition is particularly prevalent among workers who carry heavy loads, office workers who spend most of their time sitting in an awkward posture in front of a chair or computer, and housewives who spend long hours standing at the sink. The causes of these spinal conditions vary, including disc disease, ankylosing spondylitis, spinal stenosis, spondylolisthesis, spondylolysis, internal disc herniation, acute and chronic lumbar sprains, straight neck, and turtle neck. However, most cases are accompanied by stiffness in the muscles that support the spine, and thus, simply relaxing these muscles can provide significant relief.

[0003] Recently, various methods have been studied to effectively improve the aforementioned spinal conditions, one of which is spinal decompression physical therapy using spinal traction. The basic principles of spinal traction have long been practiced by chiropractors, osteopaths, and other properly trained health professionals. Both traction and decompression therapy are applied with the goal of relieving pain and promoting an optimal healing environment for disc bulges, degenerative discs, or herniated discs. Pain is relieved by creating negative pressure within the disc, which promotes shrinkage or repositioning of the herniated or bulging disc material and / or the creation of low pressure within the disc, which promotes the influx of healing nutrients and other substances into the disc. Additionally, spinal decompression is used to relieve pressure on the spinal cord or one or more compressed nerve roots passing through the spine. Decompression of spinal nerve components is a key component in the treatment of spinal disorders such as radiculopathy, myelopathy, and claudication. Spinal decompression therapy involves lengthening the spine using traction or electrical devices, aimed at alleviating low back pain. Devices that apply traction to the torso to facilitate spinal disc decompression and provide relief from low back pain are known in the art. However, current decompression devices are bulky, difficult to operate, and require the user to remain in a single position, such as lying prone on a table. Furthermore, current devices are limited to certain torso types, making them unsuitable for individuals who may be experiencing significant pain.

[0004] Therefore, there is a need for a new concept traction device that can easily allow individuals to receive spinal traction decompression treatment at home by combining the structure of a hospital traction / decompression therapy device that is too large and expensive to use at home and a home massage bed, and accordingly, research on traction methods utilizing traction devices is also necessary.

[0042]

[0043] Hereinafter, with reference to the drawings, a traction device (1) for traction of the spine of a subject according to the present invention will be described.

[0044]

[0045] A traction device (1) for traction of a subject's spine according to one embodiment of the present invention includes a massage module driving unit (100) for driving a massage module (110) capable of massaging the subject along the longitudinal direction of the subject's spine, a bed plate driving unit (200) for adjusting the gap between two bed plates (10) supporting the subject, and a control unit (300) for adjusting the force of the massage module driving unit (100) and the bed plate driving unit (200).

[0046]

[0047] Referring to FIG. 1, a traction device (1) according to one embodiment of the present invention includes a massage module driving unit (100), a bed plate driving unit (200), and a control unit (300).

[0048] A traction device (1) according to one embodiment of the present invention is basically equipped with a structure that tractions the spine of a subject while adjusting the gap between two bed plates (10), and further, a massage module (110) is arranged in the traction device (1) so as to massage the spine muscles of the subject.

[0049] The massage module (110) moves in the longitudinal direction of the subject's spine from the traction device (1) and serves to relax the muscles surrounding the subject's spine. The massage module drive unit (100) serves to move the massage module (110) in the longitudinal direction of the spine.

[0050] The bed plate drive unit (200) plays a role in adjusting the gap between two bed plates (10) that support the subject in the traction device (1).

[0051] The control unit (300) plays a role in controlling the power of the massage module driving unit (100) and the bed plate driving unit (200), and plays a role in adjusting the power for each driving unit through data obtained from sensors to be mentioned below.

[0052]

[0053] In a traction device (1) for traction of a subject's spine according to one embodiment of the present invention, the bed plate driving unit (200) may include a rod member (210) that is coupled to the lower surface of one of the two bed plates (10) and extends downward diagonally, and a driving means (220) that is coupled to the rod member (210) and provides force.

[0054]

[0055] Looking at FIGS. 2 and 3, one can see the bed plate drive unit (200) of the traction device (1) according to one embodiment of the present invention.

[0056] A bed plate driving unit (200) according to one embodiment of the present invention includes a rod member (210) and a driving means (220).

[0057] The rod member (210) is connected to the lower surface of the bed plate (10) and extends downward diagonally. The rod member (210) can be manufactured so that its length can be changed, as in a typical actuator configuration. The driving means (220) is connected to the rod member (210) to provide force, so that the rod member (210) can push or pull the bed plate (10). The driving means (220) can be configured as a cylindrical actuator, but is not limited thereto.

[0058]

[0059] A traction device (1) for traction of a subject's spine according to one embodiment of the present invention may include a force sensor unit (400) that measures a force measurement value (F), which is a reaction force of the force applied by the bar member (210) to the lower surface of the bed plate (10).

[0060]

[0061] Referring to FIGS. 1 and 3, the traction device (1) according to one embodiment of the present invention may further include a force sensor unit (400).

[0062] The force sensor unit (400) can be placed on the bed plate drive unit (200). The force sensor unit (400) measures a force measurement value (F), which is a reaction force of the force that presses the lower surface of the bed plate (10) of the rod member (210). Therefore, the control unit (300) can control the bed plate drive unit (200) through the force measurement value (F) measured by the force sensor unit (400).

[0063]

[0064] A traction device (1) for traction of a subject's spine according to one embodiment of the present invention may further include a position sensor unit (500) that is positioned on a lumbar belt (610) that fixes the subject's lumbar spine and measures that the subject's lumbar spine is fixed to the lumbar belt (610).

[0065]

[0066] Referring to Fig. 6, a traction device (1) for traction of a subject's spine according to one embodiment of the present invention may further include a position sensor unit (500). The position sensor unit (500) is placed on a lumbar belt (610) that fixes the lumbar vertebrae, and detects when the subject's lumbar vertebrae is fixed to the lumbar belt (610).

[0067]

[0068] In a traction device (1) for traction of a subject's spine according to one embodiment of the present invention, the control unit (300) can control the driving means so that the amplitude of the force measurement value (F) is formed within a certain range or less with respect to a set value, which is a value of the force of the driving means set by the control unit (300).

[0069]

[0070] The control unit (300) of the traction device (1) according to one embodiment of the present invention can control the driving means (220) through the force measurement value (F).

[0071] Referring to Fig. 7, one can see the drawing (a) in which the rod member (210) of the bed plate drive unit (200) is arranged in the most contracted state, and the drawing (b) in which the rod member (220) is arranged in the most elongated state. As in Fig. 7 (a), when the bed plates (10) are arranged closest to each other, the angle θA between the rod member (210) and the bed plate (10) is formed to be the largest, and this time is indicated as point A in Fig. 8. Therefore, when the bed plate (10) is moved constantly with the same plane direction force, the force of the driving means (220) required at point A is formed to be the largest. This is because the degree to which the force of the driving means (220) is wasted in the vertical direction is the largest at point A. In contrast, when the bed plates (10) are spaced the farthest apart from each other as in (b) of FIG. 7, the angle θB between the bar member (210) and the bed plate (10) is formed to be the smallest, and this time is indicated as point B in FIG. 8. Therefore, when the bed plate (10) is moved constantly with the same plane direction force, the force of the driving means (220) required is formed to be the smallest at point B. This is because the degree to which the force of the driving means (220) is wasted in the vertical direction is the smallest at point B.

[0072] At this time, looking at Fig. 8, it can be seen that the force measurement value (F) is formed to be the largest at point A and the smallest at point B. Since the force measurement value (F) is the reaction force of the force generated from the driving means (220), the graph of Fig. 8 can be considered a natural graph. What is noteworthy here is that the force measurement value (F) has an amplitude. The amplitude of the force measurement value (F) is a vibration generated when the bar member (210) pushes or pulls the bed plate (10). If the amplitude value is formed too large, problems such as vibration noise being generated in the bed plate (10) or the spine of the subject being startled by suddenly moving the spine may occur. Therefore, the control unit (300) sets the amplitude of the force measurement value (F) to be less than a certain range (α) with respect to the set value, which is the force value of the driving means (220).

[0073] Referring to Fig. 8, as mentioned above, the setting value of the driving means (220) at point A is formed to be the largest, and the setting value of the driving means (220) at point B is formed to be the smallest. Accordingly, the amplitude of the force measurement value (FA) at point A is formed to be the largest, and the amplitude of the force measurement value (FB) at point B is formed to be the smallest. At point A, where the spinal traction is the smallest, there is little risk of the subject's muscles being startled by the amplitude. On the other hand, at point B, since the subject's spine is already in a state where the traction is maximum, even a small shock applied to the spine can cause spinal injury. Therefore, as the distance of spinal traction to the subject from point A to point B increases, the amplitude of the force measurement value (F) can be designed to decrease.

[0074] The control unit (300) can set the force of the vibration means (220) to 2 to 3% of the set value for a certain range (α). If the certain range (α) exceeds 3%, there is a high possibility that a large vibration will occur at point A, which may cause a noise problem, and an impact may be applied to the subject's spine at point B. If the certain range (α) is less than 2%, a large force is required to move the bed plate (10) at point A, but if the vibration is formed too small in reality, the force to move the bed plate (10) may be excessively small, resulting in a small traction force.

[0075]

[0076] Figures 4 and 5 are flowcharts of a method for traction of a subject's spine according to one embodiment of the present invention.

[0077]

[0078] A method for traction of a subject's spine according to one embodiment of the present invention includes an alignment step (S401) of aligning the position of the subject based on the lumbar vertebrae of the subject, a massage step (S402) of massaging the subject's spine line while the massage module (110) of the traction device (1) reciprocates, and a traction step (S403) of traction of the subject's spine while two bed plates (10) of the traction device (1) are spaced apart from each other after the massage step.

[0079]

[0080] Referring to FIG. 4, a method for traction of a subject's spine according to one embodiment of the present invention includes an alignment step (S401), a massage step (S402), and a traction step (S403).

[0081] The alignment step (S401) is a step for aligning the position of the subject based on the lumbar vertebrae. The lumbar vertebrae of the subject is placed on the lumbar belt (610) mentioned above, and the position sensor unit (500) can measure that the subject has completed the alignment step. The length of the subject's spine and body size vary from person to person, but if the lumbar vertebrae are fixed to a single point of the traction device (1), the error between people is reduced. Therefore, the position of the subject is aligned based on the lumbar vertebrae.

[0082] The massage step (S402) is a step in which the massage module (110) reciprocates and massages the subject's spinal line. If traction on the spine is initiated when the subject's spinal muscles are not relaxed, injury may occur due to sudden shortening of the spinal muscles. Therefore, the massage step (S402) is a step in which the muscles surrounding the spine are relaxed before traction of the subject's spine, thereby preventing the subject's spine from being surprised by sudden stretching during traction.

[0083] The traction step (S403) is a step in which two bed plates (10) supporting the subject are separated from each other in order to traction the subject's spine. Each bed plate (10) is provided with a lumbar belt (610) and a thoracic belt (620), so that in the traction step (S403), the subject's spine can be tractioned while the lumbar and thoracic vertebrae are fixed.

[0084]

[0085] In a method for traction of a subject's spine according to one embodiment of the present invention, the traction step may include a first traction step (S501) in which the spine is traction toward the subject's legs by the traction force of the bed plate (10), and a second traction step (S502) in which the massage module (110) applies pressure to the spine near the lumbar region toward the subject's head.

[0086]

[0087] Referring to FIG. 5, a traction step according to an embodiment of the present invention includes a first traction step (S501) and a second traction step (S502). The first traction step (S501) is a step in which the spine is traction toward the legs of the subject, and the second traction step (S502) is a step in which the massage module (110) presses the spine near the lumbar vertebrae toward the head of the subject. The first traction step (S501) and the second traction step (S502) may be operated simultaneously or separately. When the first traction step (S501) and the second traction step (S502) are operated simultaneously, the force of the massage module (110) and the traction force of the bed plate (10) act in opposite directions, so that a force for traction of the spine of the subject can be effectively generated.

[0088]

[0089] In a method for traction of a subject's spine according to one embodiment of the present invention, in the massage step (S402), the massage module (110) may be characterized by reciprocating along the entire spine line of the subject, and in the traction step (S403), the massage module (110) may be characterized by reciprocating around the lumbar region of the subject.

[0090]

[0091] The area where the massage module (110) massages the spine of the subject can be formed differently in the massage step (S402) and the second traction step (S502). The massage step (S402) is characterized by moving back and forth along the entire spine line of the subject, thereby allowing the muscles of the entire spine to be relaxed. In contrast, the traction step (S403) is characterized by moving back and forth around the lumbar region of the subject. This is, firstly, to massage the lumbar region, which is the main target area of ​​spinal traction, and secondly, to position the massage module (110) so as to correspond to the force of the bed plate (10) stretching in the leg direction in the traction step (S403).

[0092]

[0093] In a method for traction of a subject's spine according to one embodiment of the present invention, the traction step (S403) may include a third traction step (S503) in which the traction force of the bed plate (10) does not increase when the massage module (110) moves in the leg direction.

[0094]

[0095] The traction step (S403) of the method for traction of the spine of a subject according to one embodiment of the present invention may further include a third traction step (S503).

[0096] The third traction step (S503) is a step in which the traction force of the bed plate (10) does not increase when the massage module (10) moves in the leg direction. If, when the massage module (10) moves in the leg direction and the bed plate (10) moves and generates a traction force in the leg direction, there is a risk that the subject may slip on the bed plate (10) because there is no opposing force from the massage module (10). Therefore, in the third traction step (S503), the traction force of the bed plate (10) is prevented from increasing when the massage module (110) moves in the leg direction.

[0097]

[0098] In a method for traction of a subject's spine according to one embodiment of the present invention, as the magnitude of the traction force of the bed plate (10) in the first traction step (S501) increases, the head-direction traction force of the massage module (10) in the second traction step (S502) may increase.

[0099]

[0100] The first traction step (S501) and the second traction step (502) generate forces reciprocally, and play a role in controlling the traction force on the spine of the subject. For example, as the magnitude of the traction force of the bed plate (10) in the first traction step (S501) increases, the traction force of the massage module (10) toward the head in the second traction step (S502) becomes larger. In other words, by making the moving force of the bed plate (10) and the moving force of the massage module (10) correspond to each other, the opposing force applied to the subject can be balanced, thereby reducing the possibility of the subject slipping off the bed plate (10).

[0101]

[0102] In a method for traction of a subject's spine according to an embodiment of the present invention, in the first traction step (S501), the control unit (300) of the traction device (1) can cause the amplitude of a force measurement value (F), which is a reaction force of a force applied to the lower surface of the bed plate (10) by a rod member (210) of a bed plate drive unit (200) coupled to the bed plate (10) to traction the bed plate (10), to be formed to be less than a certain range (α) with respect to a set value, which is a value of a force in a drive means (220) of the bed plate drive unit (200) set by the control unit (300). Referring to FIG. 5, it can be seen that in the first traction step (S501), if the force measurement value (F) amplitude is smaller than the set value * certain range (α), the process proceeds to the second traction step (S502), and if the force measurement value (F) amplitude is greater than the set value * certain range (α), the control unit (300) adjusts the bed plate drive unit (200) again through the control unit (300) adjustment.

[0103]

[0104] In a method for traction of a subject's spine according to one embodiment of the present invention, in the first traction step (S501), the control unit (300) sets the amplitude range of the force measurement value to an error range, and in the second traction step (S502), the control unit (300) can form the amplitude range of the traction force of the massage module (110) within the error range.

[0106] Referring to FIG. 5, the control unit (300) sets the amplitude range of the needle measurement value (F) to an error range in the first traction step (S501). At this time, by ensuring that the amplitude range of the traction force of the massage module (110) is formed within the error range, vibration noise or impact to the subject is not generated due to the movement of the massage module (110) in the second traction step (S502). The amplitude of the traction force of the massage module (110) can be measured by a massage module force sensor unit (not shown) formed in the massage module drive unit (100).
