Description

  More particularly, the present invention relates to a seated cervical traction device and an angle sensing method thereof.

Neck and shoulder pain is a problem that often appears in modern people.
Long-term poor posture causes pathological symptoms on the skeleton, muscles or nerves.
Such problems make people's lives inconvenient and reduce the quality of life.
Cervical pain is a common disease and is a very important issue both in the health of individuals and in the overall medical resource.

In recent years, smartphones and tablet computers have been developed, and their usage has been diversified, such as browsing online websites, watching videos, chatting with communication software, and playing games in mobile phones.
All of the above devices are portable and can be taken out and used at any time.
As a result, people can use smartphones or tablet computers no matter how short time they are waiting for a bus or train or in a car.
Moreover, since it is necessary to look down at the screen when using a smartphone or tablet computer, there is a high possibility that neck pain will occur in situations where the smartphone or tablet computer is used downward for a long time.

The above-mentioned causes are that the neck of the human body and the nearby joints such as muscles and ligaments are subjected to pressure action that is out of balance, resulting in poor blood circulation at the human neck and uncomfortable pain. It is a sensation that deforms and causes pain if it is suppressed for a long time.
In order to solve the above-mentioned problems, traditional Oriental medicine therapy uses traditional acupuncture methods for acupuncture, massage, and hot compresses to correct unreasonable pressure and reduce symptoms such as pain.
In the traditional acupuncture treatment process, the strength and balance of the applied force are difficult to control and the therapeutic effect has been greatly discounted.

Thus, the majority now uses mechanical cervical traction as a treatment.
Mechanical traction is routinely used for cervical degenerative arthritis (cervical spine) or disc herniation.
Mechanical cervical traction for patients with concurrent nerve root compression is currently the main conservative treatment for cervical shoulder pain.
Cervical traction can be divided into two types: seated type and saddle type.
The former can save space and the latter is relatively easy for the patient.
However, the weight used for the latter needs to be relatively heavy and the resistance between the body and the bed must be overcome.
However, this resistance is a little less than when lying down and pulling the lumbar spine.
At present, cervical traction is also the mainstream.

1 and 2 are a three-dimensional view and a schematic view of use of a seated cervical traction device according to the present invention.
As shown in the figure, this embodiment is a seated cervical traction device 1.
Cervical traction is mainly used to treat lesions at the cervical joint position.
When the cervical vertebra is subjected to a non-average pressure action, the blood circulation in the cervical vertebra is poor, and unpleasant sensations such as pain are generated.
Furthermore, when the cervical vertebra is subjected to compression for a long period of time, it causes skeletal deformation and the like, causing a more serious pain phenomenon.

For the situation described above, seated cervical traction is one therapeutic means.
The seated cervical traction device 1 according to the present embodiment includes a tension module 10, an overhang member 20, a traction member 33, and a sensing module 40.
The overhang member 20 is installed on one side of the tension module 10.

One end of the traction member 33 is connected to the pull module 10, and the opposite end hangs downward through one end of the overhang member 20.
The sensing module 40 is installed in a part of the pulling member 33 that hangs downward through one end of the overhang member 20, and one end point of the overhang member 20 extends downward and hangs based on an angle perpendicular to the horizontal plane. A portion of the traction member 33 exhibits a bias of a certain traction angle 310, and the traction angle 310 is detected by the sensing module 40.
In the present embodiment, the pulling angle 310 of the pulling member 33 can be sensed in the process of performing the seated cervical spine.
Thus, an operator (such as a doctor or a nurse) can know the situation of the traction angle 310 at any time, and can adjust the angle appropriately, whereby the treatment of cervical traction can achieve the best therapeutic effect.

The seated cervical traction device 1 includes a tension module 10, an overhang member 20, a traction member 33, and a sensing module 40.
The overhang member 20 further includes a rod member 21 and a wheel shaft 23.
The wheel shaft 23 is pivotally provided at one end of the rod member 21.
The opposite end of the bar member 21 is placed on one side of the tension module 10, which is perpendicular to the tension module 10.
One end of the pulling member 33 is connected to the inside of the pulling module 10.
The pulling member 33 is installed along the rod member 21 of the overhang member 20, and the opposite end hangs down to the ground through the wheel shaft 23 of the overhang member 20.
The traction member 33 includes a traction rope 30 and a traction headgear 31.
One end of the traction rope 30 is connected to the pulling module 10, and the opposite end is connected to the traction headgear 31.
The traction headgear 31 includes a fixing member 311 and at least one annular belt 312.
The fixing member 311 is fixed to the opposite end of the traction rope 30, and at least one annular belt 312 is fixed on the fixing member 311.
The sensing module 40 is installed on a part of the traction member 33 that hangs downward through one end of the overhang member 20, and the sensing module 40 is a three-axis accelerometer or a gyroscope.
The tension module 10 of this embodiment is installed above the backrest 101 of the seat 100, and a user (patient or the like) can perform traction treatment of the cervical spine while seated.

In the present embodiment, the three-axis accelerometer includes voltage values in the X-axis, Y-axis, and Z-axis directions.
When the three-axis accelerometer is placed horizontally, the X-axis and Y-axis are horizontal planes, and the Z-axis is a horizontal plane perpendicular to the X-axis and Y-axis.
When the sensor is tilted, the X-axis, Y-axis, and / or Z-axis is affected by gravity, and the voltage value changes.
Furthermore, these numerical values can be used to calculate three-axis angle change values through official calculations.
Since this part is a conventional technique, it will not be described here.
On the other hand, the gyroscope senses an angular velocity that cannot be sensed by the accelerometer, and puts the gyro that continues to rotate into a constant voltage state.
When the sensor vibrates, the gyro level changes and the surrounding voltage also changes, and the numerical integral can be calculated to derive the angle of object rotation.

3 to 6 are a usage schematic diagram of the XYZ space, a usage schematic diagram of the YZ plane, a usage schematic diagram of the XZ plane, and a usage schematic diagram of horizontal rotation of the first embodiment of the seated cervical traction device according to the present invention.
As shown in the figure, in the present embodiment, when performing seated cervical traction, the user is seated on the seat 100.
In addition, the user's back rests on the backrest 101 to fix the user's seating posture.
The user's head 2 is hung on the traction headgear 31.
When at least one annular belt 312 of the traction headgear 31 is two annular belts 312, the two annular belts 312 are a first annular belt 313 and a second annular belt 314, respectively.
The first annular belt 313 surrounds the head 2, and the inside of the first annular belt 313 contacts the chin and both cheek positions of the head 2.
The second annular belt 314 similarly surrounds the head 2, and its inner side contacts the back of the head 2.

In the present embodiment, when the treatment is performed by the seated cervical traction device 1, the pulling module 10 pulls the traction member 33 and retracts it.
The portion where the pulling member 33 hangs is retracted and stored along the direction of the wheel shaft 23 and the rod member 21.
In other words, the opposite end of the traction rope 30 pulls the traction headgear 31 in the same direction, and at the same time, the user's head 2 receives the pulling action of the traction rope 30.
In a situation where the head 2 is pulled by an external force, it moves the body in the same direction, so that the cervical spine becomes straight.
The pull module 10 can be set to a pull method such as continuous pull and hold, intermittent pull and hold, or gradual pull and hold.
In the present embodiment, the above-described pulling method can be adjusted as required by the user.
Under the above-mentioned situation, the pulling member 33 pulls and holds the head 2 for a long time, and the cervical spine is maintained at an angle under the action of external force.
By such a method, the treatment means for adjusting the cervical spine deformity is renewed.

As shown in FIG. 3, one end of the partial overhang member 20 on which the pulling member 33 hangs is shifted as a fulcrum, and one end of the overhang member 20 is set as the zero point of the coordinate axis in the three-dimensional space.
The sensing module 40 is installed on a portion where the pulling member 33 hangs down.

As shown in FIG. 4, in the two-dimensional space, the traction member 33 is at a traction angle 310 in the YZ plane.
In general, the means for seated cervical traction therapy utilizes pulling and holding the head 2.
This pull acts on the front (Y-axis direction) and directly above (Z-axis direction) of the user.
As shown in the figure, when the traction member 33 shifts by the first angle θ1 from one end of the overhang member 20, the sensing module 40 has a traction angle 310 of the traction member 33 at the first position where the traction member 33 hangs down. It is detected that the angle is θ2.
Based on the principle of similar triangles, it can be seen that the second angle θ2 is equal to the first angle θ1, so that the sensing module 40 can sense the traction angle 310 in the traction process of the seated cervical traction device.

As shown in FIG. 5, in the two-dimensional space, it can be seen that the traction member 33 has a traction angle 310 in the YZ plane.
Under normal circumstances, a seated cervical traction therapy scheme should not shift to the left or to the right.
In the process of the seated traction treatment, the traction angle 310 may change in a situation where the user's head 2 is asleep or not aware of himself / herself.
As shown in the figure, when the pulling member 33 shows a shift of the third angle θ3 from one end of the overhang member 20, the pulling angle of the pulling member 33 is detected by the sensing module 40 installed at the portion where the pulling member 33 hangs down. 310 can be detected, and the third angle θ3 can be known based on the principle of a similar triangle.

FIG. 6 shows the change in the traction angle 310.
As shown in the figure, FIG. 6 shows that the pulling angle 310 on the XY plane, that is, the first angle θ1 is similar to the pulling angle 310 of FIG. 4, but in FIG. 6, a rotation angle is further added.
When the user's head 2 rotates at a certain angle, the pulling angle 310 is similarly the first angle θ1, but does not change due to the rotation of the user's head 2.
However, the rotation of the head 2 brings about the rotation of the traction rope 30 of the traction member 33. In addition, in this situation, the cervical traction therapy is seriously affected and not effective. Can even cause serious injury.
Therefore, when the sensing module 40 senses the rotation of the traction rope 30, the traction rope 30 rotates at an angle θ4.
In this way, the angle of cervical traction can be accurately controlled, and the therapeutic effect can be enhanced.

This embodiment adds improvements to the drawbacks of the prior art.
Conventional seated cervical traction devices can be used for therapeutic means such as cervical traction.
However, in the process of performing cervical traction therapy, the head is shifted or rotated left and right in a situation where the user (patient or the like) is asleep or undetectable by himself, so that the traction angle of cervical traction is determined by the operator ( It may be different from the treatment angle of cervical spine correction originally set by a doctor or a nurse.
Under such circumstances, there is a risk that the therapeutic effect becomes poor or a situation such as cervical spine injury occurs.

Thus, this embodiment provides a seated cervical traction device and utilizes a sensing module 40 installed in the rope section of the traction member 33 where one end of the overhang member 20 hangs down.
When the pulling member 33 is pulled and the user's head is pulled and held, one end point of the overhang member 20 extends downward and is based on an angle perpendicular to the horizontal plane.
If the traction member 33 shifts the traction angle 310 with respect to this reference based on a reference of an angle perpendicular to the horizontal plane, the sensing module 40 can detect the traction angle 310.
Thus, the operator can immediately and clearly know the traction angle 310 for the user of the seated cervical traction device 1 and can make corresponding adjustments in a timely manner, thus providing the best treatment means and effects. be able to.

FIG. 7 is a schematic view of a second embodiment of the seated cervical traction device according to the present invention.
As shown in the figure, the difference between the present embodiment and the first embodiment is as follows.
The present embodiment further includes a pressure sensing module 50.
The pressure sensing module 50 is installed inside at least one annular belt 312 of the traction headgear 31.
The user wears the traction headgear 31, the first annular belt 313 of the at least one annular belt 312 surrounds the head 2, and the pressure sensing module 50 contacts the jaw position of the head 2.

In the course of cervical traction treatment, the external force pulls the traction rope 30, which causes the traction rope 30 to move the traction headgear 31.
At this time, the user's head 2 receives an external pulling action, and the head 2 receives the pull and hold of the first annular belt 313.
The main force receiving position at this time is the chin position of the head 2.
Thus, the pressure sensing module 50 can sense the traction pressure P by receiving the pull of the first annular belt 313 and the resistance pull of the jaw of the head 2.

The pressure sensing module 50 is a thin-film strain gauge that directly processes a semiconductor single chip, and can measure the pressure of gas or liquid.
The pressure sensing module 50 is a thin film capable of receiving pressure produced by a silicon crystal plate, the periphery of the pressure diaphragm is fixed, and the center of the pressure diaphragm receives the pressure of the average distribution.
The pressure is received and measured from the center of the pressure diaphragm.
Two semiconductor strain gauges are attached to the center and the periphery of the pressure diaphragm to form a Wheatstone bridge.
The pressure sensing module 50 is a bridge type pressure sensing structure, which can obtain a linear voltage output within a certain pressure range and is a measured value.
In this way, the traction pressure for the operator or the user of the seated cervical traction device 1 can be known immediately and clearly, and the corresponding adjustment can be made in a timely manner. An effect can be provided.

FIG. 8 is an electrical connection schematic diagram of one embodiment of a seated cervical traction device according to the present invention.
As shown in the figure, this embodiment further includes a storage unit 41, a display unit 43, and an alarm unit 45.
The storage unit 41, the display unit 43, and the alarm unit 45 are electrically connected to the sensing module 40 and the pressure sensing module 50, respectively.
When the sensing module 40 senses the traction angle 310, it simultaneously produces a sensing signal 400.
The storage unit 41 receives the sensing signal 400.
When the pressure sensing module 50 senses the traction pressure P, it simultaneously issues a pressure sensing signal 500.
The storage unit 41 receives the pressure sensing signal 500.
Thus, the data of the plurality of sensing signals 400 and the plurality of pressure sensing signals 500 stored can clarify the treatment process, and can be used as a basis for determining the effectiveness of treatment and subsequent processing.

Furthermore, as before, the sensing module 40 emits a sensing signal 400 and the pressure sensing module 50 emits a pressure sensing signal 500.
The display unit 43 receives the sensing signal 400 and the pressure sensing signal 500 and displays information on the sensing signal 400 and the pressure sensing signal 500.
Thus, it can be displayed immediately on the display unit 43, and the operator or user can conveniently know the current values of the traction angle 310 and the traction pressure P, and can make appropriate adjustments immediately.

Furthermore, as before, the sensing module 40 emits a sensing signal 400 and the pressure sensing module 50 emits a pressure sensing signal 500.
The alarm unit 45 receives the sensing signal 400 and the pressure sensing signal 500, and the alarm unit 45 includes a preset angle range and a preset pressure range.
If the traction angle 310 is larger or smaller than the preset angle range, the alarm unit 45 emits an alarm sound to inform the operator or user that the traction angle 310 is too large or too small.
When the traction pressure P is larger or smaller than the preset pressure range, the alarm unit 45 similarly generates an alarm sound.
In order to deal with the above-described two situations, two types of alarm sounds can be set, thereby making it convenient to notify the operator or user.

Mechanical traction is routinely used for cervical degenerative arthritis (cervical spine) or disc herniation.
Mechanical cervical traction for patients with concurrent nerve root compression is currently the main conservative treatment for cervical shoulder pain.
Cervical traction can be divided into two types: seated type and saddle type.
The former can save space and the latter is relatively easy for the patient.
However, the required pulling force to be used in the latter relatively large, has to overcome the resistance between the body and the bed.
Mainly sit-down cervical traction is the mainstream in the current.
Among them, the seated traction tends to cause a situation such as an angle shift or inappropriate control of the traction pressure in the traction process.
The deviation of the pulling angle or the inappropriate pulling pressure adversely affects the therapeutic effect and reduces the therapeutic effect.
Therefore, how to suppress these factors is very important.
