Description

Massage device for cervical vertebra {Massage Device Of Posterior Cervical muscle}

The present invention relates to a massage device for the cervical vertebrae, and more particularly, to give a massage effect by stretching through accurate and stable rotational motion in a clockwise or counterclockwise direction by a driving source in a state where the head of a human body is supported. And, in particular, it relates to a massage device for the cervical vertebrae, which guarantees reliability of operation through a simple structure and improves the convenience of economical mass production and maintenance.

As is well known, the human spine is composed of a vertebra that serves as a central body, a bow-shaped vertebral column protruding from here to the rear and upper, and various projections, and is surrounded by the vertebral body and the vertebral column at the center. A large hole is formed in the spine, and spinal diseases occur due to maintaining the wrong posture for a long time, muscle aging, or strong external impact. Most of the spinal diseases are abnormally attached to the spine. The cause can be found in living habits such as the excessive force applied, such as the usual sitting or standing posture or sleeping posture. In the case of children and adolescents in the growing period, if there is an abnormality in the spine, the growth line is compressed, and growth hormone is released accordingly. The secretion of the secretion is not smooth, which may lead to problems in that growth promotion is inhibited.

In particular, recently, as the use of smartphones increases regardless of gender and age, more and more people are suffering from cervical spine diseases, which are parts between the skull and the thoracic vertebrae, among the parts constituting the spine.

That is, the cervical vertebrae are generally referred to as neck bones among the vertebrae of our body, and are composed of seven vertebrae segments. Each transverse process of each cervical vertebrae has a hole through which the cervical artery passes, and veins and brachial plexus are located around it. , It can be said to be an important part of the body that is connected to the torso below and to the head above. The cervical vertebrae, like the thoracic and lumbar vertebrae, are greatly affected by a person's posture and can cause various musculoskeletal disorders. Have. As an example, the same cervical disc herniation as other intervertebral discs may occur, a ligament supporting the cervical spine from the back may be sprained, and cervical muscles may also be stiff due to various causes, compressing the nerves, resulting in headaches. Various diseases of the musculoskeletal system, such as cervical pain and shoulder pain, can occur.

On the other hand, the suboccipital muscle is a part of four muscles located between one side of the cervical vertebrae and the occipital bone, and consists of a total of eight muscles on both sides. ) is widely distributed and is close to the vertebral artery, so it is a muscle closely related to brain and blood pressure diseases. The suboccipital muscle connects the occipital bone and the first and second cervical vertebrae and has a close relationship thereto. If stenosis occurs in the suboccipital triangle, which surrounds the vertebral artery among the suboccipital muscles, compression occurs on the nerve, the blood supply to the brain is disturbed, and the function of the muscle spindle may be reduced. In addition, when the suboccipital muscle is stiff, it may cause a cervical headache in which the range of pain extends forward from the occipital bone to the eye and forehead in one direction. Among the suboccipital muscle group, the small laryngeal rectus muscle is an important muscle structure that plays a role in holding the spinal cord in the center. When expressed, it can create mechanical tension in the denticulate ligament and cause deformation of the dura mater surrounding the spinal nerves.

In general, for the treatment of back pain or shoulder pain, methods of treating or alleviating pathological conditions through methods such as physical therapy to strengthen muscles or smooth blood circulation by stimulating acupuncture points are widely performed. In this case, it is desirable to correct the body shape by relaxing the intervertebral disc that was pressed by widening the gap between the vertebrae.

In other words, acupressure or massage is a kind of manual procedure that corrects the modulation of the body by directly giving mechanical stimulation to the skin in a certain way using the hands to cause a bioreaction to treat diseases and improve health (手技施術), acupressure massage promotes circulation of blood or lymph, boosts metabolism, enhances tissue nutrition, excretes waste, and enhances resistance. This tactile stimulation (觸壓刺戟) stimulates the nerves and acts as an analgesic, so it promotes the recovery of paralyzed nerves and has the effect of correcting the modulation of internal functions.

However, since most of these acupressure massages cannot be performed by the person receiving treatment alone, there is a problem in that the effect is not constant because it is performed by relying on the power of a person as well as the inconvenience of having to receive type help. In order to improve these problems, various types of acupressure massagers that can receive acupressure massage by themselves have been developed and used. However, in the case of a vibrating massager, it is a method of repeatedly hitting (tapping) a part of the body, so the acupressure effect is low, and it has the disadvantage of causing secondary pain due to the hitting. Since the sphere must be pressed with a certain force to the body part, not only the inconvenience in use is great, but also the difficulty in continuous use due to the force.

In addition, in the case of an air pressure massager, pressure is repeatedly applied to a part of the body by injecting and discharging air into a cuff designed to cover a body part such as an arm, leg or waist of the body, and simply a part of the body Since it is only a massage, it is difficult to expect acupressure effects such as stimulating acupuncture points, and it is cumbersome to use because it must be worn on the arms, legs, or waist of the body. Although there is a treatment device equipped with a belt-type cuff that is inflated to provide traction force, it is also inconvenient to use because it must be worn on the neck or waist. As a result, the treatment effect was low.

In particular, as a prior art for improving the flow of cerebrospinal fluid by compressing the suboccipital muscle or its surroundings while relaxing the cervical spine, a functional cervical pillow has been proposed through Patent Registration No. 10-1665115 (October 12, 2016). Specifically, when lying down, the cervical vertebrae are maintained in a C-shape, and cervical vertebrae No. 1 are acupressure to relieve tension and pain in the neck muscles. A technology related to a functional cervical pillow capable of doing is described, which has some similarities with the present invention in that it is configured to acupressure the suboccipital muscle by acupressure on the first cervical vertebrae while maintaining the curvature of the cervical vertebrae, but the curvature of the cervical vertebrae It only maintains the cervical vertebrae, but does not include the function of relaxing the cervical vertebrae and exercising the cervical muscles, and it does not include a configuration for compressing the 4th ventricle along with the suboccipital muscles, so there is no function to relax the cervical vertebrae and facilitate the flow of cerebrospinal fluid. there is

Another prior art, Patent Registration No. 10-1077885 (2011.10.31.) relates to a myofascial relaxer for physical therapy, see. Specifically, the main body placed horizontally on the floor; Occipital bone acupressure unit protruding from one side of the main body to support and acupressure the occipital bone; a lower occipital supporting part protruding higher than the occipital bone acupressure part at a position in front of the occipital bone acupressure part of the main body to support and acupressure the lower larynx; And an upper thoracic vertebrae acupressure unit protruding from a position toward the front of the lower occipital support portion of the body to prevent the body from being pushed while supporting the back neck and to acupressure the upper thoracic vertebrae. Although the technique is described, this also has a problem in that a therapeutic effect cannot be expected because it is only a structure that uses a plurality of protrusions to simply compress the laryngeal fascia and its surroundings.

As another prior art, a 'massage device having a physical therapy function' has been proposed through Korean Patent Registration No. 10-1561005, and in claim 1, 'a base plate placed on the floor and one end of the base plate' Rotating plates that are hingedly coupled to each other and are stacked upward; a laryngeal seating portion that is slidably provided on one side of an upper surface of the rotating plate, the upper surface of which is formed with a seating groove curved to support the back of the human body, and the lower surface is open; a cervical vertebra support portion positioned on one side of the laryngeal seating portion and fixed to the pivot plate, the upper surface of which is provided to support the nape portion of the human body; It is provided with a plurality of acupressure pieces provided in the larynx seating portion and lifted by air pressure supply and exhaust, a cylinder having a plurality of accommodation spaces formed therein and a slit formed on the upper side, and one end provided inside the cylinder It is provided to be able to move up and down without being separated, and the upper end is provided in the inside of the acupressure piece and the cylinder provided to selectively pass through the acupressure piece hole formed in the laryngeal seating portion and is provided in the lifting airbag that is supplied with air pressure from the outside and selectively expands in volume. composed of acupressure elements; A rail member provided on the lower surface of the laryngeal seating portion and the upper surface of the pivot plate to support sliding forward and backward in a direction away from the cervical spine support portion, and traction for pushing or returning the laryngeal seating portion away from the cervical spine support portion a traction element having a driving unit; A drive motor provided on the other side of the base plate to generate rotational driving force by supplying power, a window formed by removing a part of the rotation plate corresponding to the drive motor, and a window provided on the upper surface of the rotation plate to engage gear with the drive motor A massage device with a physical therapy function characterized in that it is configured to include; a stretching element having a gear rail that receives driving force and guides rotation around a hinge integrally with a rotating plate.' is disclosed.

In the massage device having a physical therapy function according to the prior art, the rotating plate provided on the upper part of the base plate is rotated at a predetermined angle in the forward and reverse directions by the driving motor to give a massage effect by stretching. there is.

However, in the massage device having a physical therapy function according to the prior art, there are various problems to be solved to control the rotation plate at a predetermined angle and an accurate position in the left and right directions.

That is, the angle at which the user can incline left and right in the lying position of the rotating plate is around 0 to 45 degrees, and the effective angle for safe stretching while giving a massage effect is around 18 to 24 degrees, but in the prior art In order to set an accurate angular position, it is necessary to install a sensor for each angle, and a sensor position detection controller to obtain the position information of these sensors, and to use a servo motor for precise angle control. However, since the internal space of the massage device is narrow, there is a big problem in production and maintenance.

In addition, since the structure supports the user's head, the weight of the head directly acts on the rotating plate, so there is a frequent difference between the angle by the drive rotation value of the servomotor and the rotation angle of the actual rotating plate, so there is a problem of frequent correction. there was.

In addition, when the power of the massage device is cut off during use, the rotating plate must be returned to the initial position, but there is no suitable alternative for this. A method of returning the position by measuring the amount of load acting on the motor is sometimes used, but this method requires measuring the load on the driving motor, so it not only requires an expensive sensing circuit, but also shortens the lifespan due to overloading of the driving motor and gears for rotating the rotating plate. There was an evil that caused their damage.

Patent Publication No. 10-2010-0113330, (2010.10.21.) Patent Publication No. 10-2011-0104347, (2011.09.22.) Registered Patent No. 10-1257732, (2013.04.18.) Registered Patent No. 10-1468845, (2014.11.27.) Registered Patent No. 10-1561005, (2015.10.08.)

It is a configuration disposed on the open space to detect the sensing pins provided on the support plate 15 .

The rotation control module 30 is installed on one side of the lower cover 13 and has an outer sensor 31 and an inner sensor 32 having different rotational trajectories around the shaft groove 13a, and the outer sensor 31 And the inner sensor 32 is a sensing pin element for sensing, and is composed of a plurality of sensing pins disposed on the rotational trajectory of the outer sensor 31 and the inner sensor 32 on one side of the upper surface of the support plate 15 .

The outer sensor 31 and the inner sensor 32 are sensing elements for sensing the sensing pins, and an optical sensor, a contact sensor, or a magnet sensor may be used, and generate a sensing signal when passing through the sensing pins. And it is configured to apply it to the driving motor 21 or the motor drive. Here, the drive motor 21 may be controlled to start a return drive after a predetermined time delay when a sensing signal is applied from the sensing pins, or may be controlled to be rotationally displaced at a different angle. Since this control configuration may be implemented by a known technique, a detailed description thereof will be omitted.

The sensing pins are the base plate 15 in which the outer sensor 31 and the inner sensor 32 can simultaneously generate a sensing signal in a state in which the main body 10 is not rotated, that is, in a state shown in FIG. 1 or 6 ) It is a configuration in which an outer center pin 31c and an inner center pin 32c are provided on one side of the upper part, and the outer center pin 31c and the inner center pin 32c at this time are perpendicular to the hinge axis 15a It is a configuration that is arranged left and right based on the line.

That is, when the outer center pin 31c and the inner center pin 32c are sensed at the same time, the main body 10 returns to its initial position without being rotated to the left or right.

In addition, an outer left pin 31l and an outer right pin 31r having an angle range are provided to generate a detection signal within a range of 1 to 20 degrees to the left and right of the outer center pin 31c, respectively, and the inner An inner left pin 32l and an inner right pin 32r are provided so that the inner sensor 32 generates a detection signal within a range of 21 to 30 degrees to the left and right of the center pin 32c, respectively.

At this time, since the outer left pin 31l and the outer right pin 31r and the inner left pin 32l and the inner right pin 32r are disposed on different rotational trajectories, the outer sensor 31 and the inner sensor 32 simultaneously detect It is placed undetected.

Therefore, when the user wants to be stretched at the rotation angle detected by the outer sensor 31, when the support plate 15 rotates to the left, the drive motor until the outer sensor 31 detects the outer right pin 31r. is operated, and when it rotates to the right, the driving motor is operated until the outer sensor 31 detects the outer left pin 31l.

Similarly, when the user wants to be stretched at the rotation angle detected by the inner sensor 32, when the support plate 15 rotates to the left, the drive motor until the inner sensor 32 detects the inner right pin 32r. is operated, and when it rotates to the right, the driving motor is operated until the inside sensor 32 detects the inside left pin 32l.

If you want to receive stretching by using the outer sensor 31 and the inner sensor 32 together, it is not shown, but it can be implemented through a known circuit configuration such as a microcomputer, and since this corresponds to a known technology, detailed description is omitted. do.

On the other hand, in the present invention, the outer sensor 31 proposes the position of the sensing pins to sense within the range of 1 to 20 degrees, and as a preferred embodiment, the outer left pin 31l and the outer right pin have an angular range of 18 degrees in the drawing. The configuration in which (31r) is arranged is shown.

In addition, the position of the sensing pins is proposed so that the inner sensor 32 is also sensed within the range of 21 to 30 degrees, but preferably the inner left pin 32l and the inner right pin 32r are arranged to have an angular range of 22 degrees. is illustrated in the drawing. Of course, it can be sufficiently considered in the design that the outer left pin 31l and the outer right pin 31r and the inner left pin 32l and the inner right pin 32r can be disposed in other angular ranges.

Finally, the present invention detects the inner right pin 32r and the inner left pin 32l so that they can return to the initial position as shown in FIG. 6 when the drive motor 21 suddenly stops due to a power failure or a device failure. A configuration in which an inner left end pin 32le and an inner right end pin 32re, which are pin elements for use, are additionally installed is proposed.

That is, the inner left end pin 32le and the inner right end pin 32re set the rotation end position to the inner sensor 32 in order to return to the initial position when the driving motor 21 is restarted after being forcibly stopped due to power failure or equipment error. ), in the present invention, the configuration of arranging the inner left end pin 32le and the inner right end pin 32re to the outer side of the inner right pin 32r and the inner left pin 32l is exemplified. did

Describing the operation of the inner left end pin 32le and the inner right end pin 32re, the power of electric components including the drive motor 21 is turned on at an arbitrary position while the base plate 15 rotates to the left or right. If it is restarted after being cut off, it is impossible to determine how much the main body 10 has rotated with respect to the support plate 15.

In this state, when power is applied to the drive motor 21, the drive motor 21 generates a rotational force at a predetermined angle in the forward or reverse direction, and the drive gear 23 moves left or right along the curve gear 25. will start rotating. At this time, if the outer sensor 31 and the inner sensor 32 read the detection information at the same time, it is detected that the main body 10 has been restored to the initial position, and if not, the driving motor 21 does not stop and continues driving force. is generated to drive the inner sensor 32 until it reaches the inner left pin 32l and the inner right pin 32r. If the inner sensor 32 detects the inner left pin 32l or the inner right pin 32r, the sensing information is applied to the drive motor 21 so that the return operation can proceed.

On the other hand, if the inside sensor 32 is forcibly terminated after reaching the left inside pin 32l and the right inside pin 32r, or the user applies excessive force, the left inside pin 32l and the right inside pin 32r are slightly moved outward. If the device is in a forced stop state at a position out of position, it detects the inner left end pin 32le and the inner right end pin 32re disposed on the outside of the inner left pin 32l and the inner right pin 32r, respectively, to detect this. The position is recognized as the rotation end point and a return operation is performed.

On the other hand, the present invention is not limited to the described embodiments, it is possible to change and use the application site, and various modifications and variations can be made without departing from the spirit and scope of the present invention. It is self-evident to those who have knowledge. Therefore, such variations or modifications should fall within the scope of the claims of the present invention.
