Description

Pelvic correction belt of a walking wearer {PELVIC CORRECTION BELT FOR WEARER DURING WALK}

The disclosed technology relates to a belt that corrects the movement of the pelvis while the wearer is walking.

Recently, diseases related to the musculoskeletal system are increasing due to an increase in use of a visual display terminal (VDT) such as a computer or a smart phone. A long sitting posture causes deformation of the turtle neck and shoulders, which extends the head forward than the normal vertebral centerline, and induces a crooked posture of the spine, reducing only the lumbar vertebrae and increasing the pressure and stress of the spine.

On the other hand, the ideal posture in the human body is defined as a balanced state with the least pressure and stress on the spine by forming a smooth curve that crosses only the anterior and posterior of the spinal column. The normal spine curvature forms the cervical spine, the lumbar spine lordosis, the thoracic spine, and the sacral spine form the kyphosis, which plays a role in maintaining the balance of the spine and pelvis against the center of gravity of the human body.

The total curvature of the lumbar region plays the most important role in the erect posture, and the decrease in lumbar lordosis is the main factor causing the sagittal imbalance. The posture in which the kyphosis of the thoracic spine and the lordotic curve of the lumbar spine are reduced is defined as “flat lumbar posture”. When the pelvis is inclined to the rear, the spine becomes straight, increasing the stress stress of gravity applied to the spine, and the ability to move the weight is disturbed in the front and both directions. Walking forward is restricted and walking speed and steps are reduced. As a result, it causes pain in the lumbar region and has an inefficient gait pattern.

The pelvic position plays an important role in good posture by reducing weight on the vertebral body and each joint, reducing external shocks, and preventing soft tissue tension and deformation. Among them, the pelvis supports the abdomen and connects the spine and lower limbs to support weight. It is an important part that makes the upper body move smoothly by keeping the trunk in a stable position and maintaining a stable base. Therefore, the position of the pelvis serves to maintain the correct posture and to adjust the effective walking.

Referring to Korean Patent Publication No. 10-2015-0143271 (invention name: posture corrector), there is disclosed a posture corrector that is mounted on a body and corrects distortion of a lower pelvis or rib cage. However, such a posture corrector has a problem in that posture correction performance is guaranteed when the wearer maintains a stationary posture such as sitting or standing, but performance of posture correction is somewhat deteriorated when the wearer moves such as walking or climbing stairs.

The disclosed technology provides a pelvic correction belt that induces pelvic movement into normal categories while the wearer is walking and periodically monitors the pelvic movement.

The first aspect of the disclosed technology to achieve the above technical problem is a band that controls the movement of the pelvis by applying constant pressure to the pelvis of the wearer, and is connected to the band through a groove formed in the center of the body and is disposed at the lumbar aft of the wearer When the wearer is walking, at least one pair is placed on each of the pair of supports and the pair of supports that push the wearer's lumbar aft forward and induce the movement of the pelvis forward by using the pressure, and the pressure is applied It is to provide a pelvic correction belt of a walking wearer including a sensor module that senses the movement of the pelvis by comparing the intensity.

1 is a rear view of a pelvic correction belt of a walking wearer in accordance with one embodiment of the disclosed technology. And FIG. 2 is a front view of a pelvic correction belt of a walking wearer according to one embodiment of the disclosed technology. 1 and 2, the pelvic correction belt of the walking wearer includes a band 110, a support 120, and a sensor module 130.

The band 110 controls the movement of the pelvis by applying constant pressure to the pelvis of the wearer. In one embodiment, the band 110 may control the movement of the pelvis based on MWM (Mobilization With Movement) technique. That is, it may be to induce normal movement in the restricted joint by using the force generated through the movement of the wearer himself.

On the other hand, in order to improve the alignment of the flat lumbar vertebrae, the band 110 controls the forward tilt, especially among the movements of the pelvis. That is, in order to prevent the lumbar lordosis angle from being reduced, instead of directly applying pressure to the lumbar vertebra, the angle of the pelvis connecting the upper and lower bodies is inclined forward, so that the lumbar angular angle is not reduced and the pelvis tilts backward prevent. The band 110 is formed of a material having a certain elasticity or more, and when the wearer wears it on the waist like a normal belt, the pelvis is tightened with a certain force according to the elasticity. Accordingly, the wearer can walk while maintaining a stable body balance.

The support 120 is disposed on the rear portion of the band 110. As shown through FIGS. 1 and 2, the support 120 may be formed with a groove through which the band 110 passes in the center of the body so as to be integrally provided with the band 110. Then, it is inserted into the center of the body of the band 110, and when the wearer puts the band 110 around the waist, it is positioned at the aft of the lumbar spine.

Meanwhile, the supporter 120 induces the movement of the pelvis forward by pushing the wearer's lumbar cove forward using pressure generated through the band 110 when the wearer is walking. In this process, since the wearer may feel pain due to excessive pressure, a separate cushioning member may be further provided on a surface in close contact with the waist. For example, a rubber-like member such as latex may be padded on the inner surface in close contact with the waist.

On the other hand, the support 120 according to an embodiment of the disclosed technology is provided with a pair in one band (110). For example, one can be disposed on the left and right of the lumbar spine, respectively, to support the left and right sides of the lumbar tail.

At least one sensor module 130 is disposed on each of the pair of supports 120. That is, as few as one, as many as one of the supports may be arranged, and the other supports may also be provided in the same manner. The sensor module 130 detects the movement of the pelvis by comparing the intensity of the pressure. As described above, the angle of the pelvis is guided forward due to the force of pushing the lumbar aft forward, and the sensor module 130 can detect whether the angle of the pelvis maintains a normal category.

3 is a view showing a state in which the pelvic correction belt according to an embodiment of the disclosed technology is mounted. Referring to FIG. 3, while walking while wearing a belt, the belt serves to provide forward pelvic acceleration and stability to the pelvis by applying a mechanical pelvic anterior tilting. Therefore, when subjects with flat lumbar vertebrae wear a belt and walk, they push the alignment of the pelvic posterior tilted forward to form a normal lordotic curve of the lumbar spine along with pelvic anterior tilt. It is possible to assist in keeping the spine aligned correctly. In addition, the normal angular angle properly distributes the gravitational stress applied to the lumbar spine, and self-mobilization of the joint is made to induce efficient walking when walking.

Meanwhile, as shown in FIG. 3, it was confirmed that the anterior-posterior movement of the trunk and pelvis promoted as a result of the test in which the belt was actually worn to maintain gait for a certain period of time. For the promotion of pelvic anterior tilt created by the belt, the trunk is expected to exhibit a reflexive motion that pulls the upper body back. Such interbody extension movement is an exercise that helps to induce the normal lordosis angle of the lumbar spine by strengthening the extensor muscles of the lumbar region, and this movement can be promoted by using a belt according to the disclosed technique.

4 is a view showing a support according to an embodiment of the disclosed technology. Referring to Figure 4, the support 120 is formed of a plurality of layers. In one embodiment, as shown in Figure 4, the inner surface of the support 120 may be formed of a latex layer 401 and the outer surface of a plastic layer 402. Here, the inner surface means a portion that comes into contact with the wearer's waist, and the outer surface means a portion that is connected to the outer surface of the band 110. That is, the latex layer 401 serves to prevent pain caused by strong pressure, thereby inducing a natural movement of the wearer.

On the other hand, as shown in Figure 4, the sensor module 130 is provided on the inner surface of the support 120. The sensor module 130 includes a pressure sensor and detects the pressure transmitted to the inner surface of the support 120 by using the pressure sensor, so that when the wearer is walking, it can sense the left and right symmetrical state or detect the front tilt angle of the pelvis. have.

In one embodiment, the sensor modules 130 provided on both sides of the pair of support 120 may compare the pressure transmitted to the left and right of the pelvis when the wearer is walking, thereby detecting the symmetry state of the pelvis. At this time, the sensor module 130 is provided on the left support and the one provided on the right support assumes that pressure sensors having the same sensitivity are disposed at the same height. If the pressures detected by the pressure sensors on both sides are similar, it can be judged that the symmetry of the left and right pelvis is good. At this time, the sensor module 130 may determine whether the symmetry is performed by comparing the reference value and the two pressures using a predetermined reference value, respectively.

Meanwhile, a groove 403 in which the band 110 is inserted is provided in the center of the body of the support 120. The size of the groove 403 matches the width of the band 110 and can be connected in such a way that it is tightened or fixed after moving to the center by inserting one end of the band 110.

Meanwhile, the sensor module 130 is connected to the wearer's smart terminal. Although not illustrated through the drawings, the sensor module 130 includes a module capable of performing short-range wireless communication with a smart terminal. For example, data can be exchanged by Bluetooth or RFID. The sensor module 130 transmits a signal for an alarm to the smart terminal when the movement of the pelvis exceeds the reference value. The smart terminal may provide an alarm to the wearer through at least one of voice, message, and image according to the transmitted signal.

On the other hand, the smart terminal connected to the sensor module 130 can calculate the angle at which the pelvis is inclined forward based on the value of detecting the movement of the pelvis. In one embodiment, the smart terminal may store an application indicating how much an angle the pelvis is inclined forward based on the value detected by the sensor module 130. The smart terminal may calculate how much the wearer's pelvis is tilted forward based on the detection result transmitted from the sensor module 130.

The smart terminal can display the stress index applied to the wearer's pelvis on the screen according to the angle at which the pelvis is inclined forward, and various outputs can be displayed on the screen for easy visual identification. For example, a stress index applied to the pelvis may be displayed on the screen using colors, graphs, or text.

5 is a view showing the movement of the pelvis during walking. And Figure 6 is a view showing the movement of the pelvis is symmetrical. Referring to FIGS. 5 and 6, it can be seen that the pelvis is inclined to a position opposite to the stepping feet in the process of walking while alternately crossing the left and right legs. For example, as shown in FIG. 5, when the left foot is forward, the left pelvis is tilted backward. And, as shown in FIG. 6, when the right foot is stepped forward, the right pelvis is inclined backward.

Naturally, in the case of a person with a normal body balance, the pelvic movement occurs symmetrically left and right because there is no large deviation between the steps of the left and right steps or the step of the foot. However, when the balance of the body collapses, the movement shifted to one of the pelvis appears. Therefore, the sensor module 130 is disposed on a pair of supports to detect whether the pelvis is symmetrical, and compares the difference in pressure generated by the movement of both pelvis to determine whether it is symmetrical.

7 is a view showing monitoring information displayed on a smart terminal screen. Referring to FIG. 7, information on the user's smart terminal 701 is displayed on the screen of the user's smart terminal 701 to monitor the left and right balance of the pelvis and the angle at which the pelvis is tilted forward according to the pressure generated while walking. When the wearer walks in a state of holding the smart terminal 701 that communicates wirelessly with the sensor module 130, the wearer may calculate a result displayed on the screen based on the sensed value of the pressure transmitted from the sensor module 130. For example, an AP mounted on a smartphone performs an operation on a sensed value and reference values for comparing states can be stored in the memory. And the information can be visually displayed through the pre-installed application.

The pelvic correction belt of a walking wearer according to an embodiment of the disclosed technology has been described with reference to the embodiment shown in the drawings for ease of understanding, but this is only exemplary, and those skilled in the art can It will be understood that various modifications and other equivalent embodiments are possible. Therefore, the true technical protection scope of the disclosed technology should be defined by the appended claims.
