Lumbar and cervical traction weighing device {Lumbar and cervical traction weighing device}

The present invention relates to a lumbar and cervical vertebrae traction weight measurement device, and more particularly, to a device capable of horizontally towing and measuring the weight of the lumbar and cervical vertebrae with a single traction motor and a single load cell.

The spine is one of the most important bones that make up the human body and is an organ that forms the center of the body and serves as a pillar. The spine supports the head above and connects to the pelvis below to support the body, help move the body, and protect the spinal cord and spinal nerves.

In modern people's lives, as the use of smartphones, PCs and smart devices has become commonplace, spinal diseases such as turtle neck and disc are increasing. , there are various diseases of tumors.

On the other hand, 80% to 90% of spinal diseases are treated with non-surgical treatment methods, non-surgical treatment methods are the basic treatment methods, and even if surgery is performed, non-surgical treatment methods are used for rehabilitation and recurrence prevention treatment.

Therefore, posture correction is an essential treatment process in the correction or rehabilitation treatment of spinal disorders.

For example, patients with spinal diseases must be corrected in the correct posture because the spine is bent or bent. If the patient is treated without correction, zero-gravity decompression therapy will not be effective, and accidents such as spinal joint damage or serious paraplegia will occur. can

In addition, since it is difficult to control the appropriate exercise intensity when the patient arbitrarily performs without expert training or assistance, there is a high risk of recurrence of muscle and ligament damage including the spine.

In order to solve this problem, Korean Patent Registration No. 10-2188342 “Spine and pelvis traction and correction device and its control method” is a control method that tractions the spine and pelvis at the same time and adjusts the gap between beds through hinge coupling However, if the angle of the bed is distorted, there is a risk that the spine may be strained if the spine is towed in an uncorrected state due to the nature of the spine patient.

The lower bed 140 including the lower bed 141 formed at a certain distance from the central bed part 130 and fixed to the support 110 on which the lower body of the hip, thigh, and leg of a patient with a spinal disease is seated. ).

The sensor unit for measuring the cervical and lumbar position of the patient includes the cervical detection sensor 161 formed at the lower part of the seat surface of the middle bed 131 and the lower part of the seat surface of the middle bed 131 formed at the starting positions of the patient's cervical vertebrae (C7, C6). It includes a lumbar detection sensor 163 formed at the patient's lumbar starting position (L1, L2).

Figure 3 is a plan view and a front view of the lumbar and cervical spine traction weight measuring device according to the present invention.

As shown, the bed formed so that the patient can lie down is divided into an upper bed portion 120, a middle bed portion 130, and a lower bed portion 140, and the bed is a guide installed on the upper surface of the support 110 placed on rails

In the apparatus for measuring the weight of the lumbar and cervical vertebrae by towing the upper bed, the body is fixed to one side of the support 110 and the piston rod of the other side is connected to the lower surface of the central bed 130, but the end of the piston rod is attached to a guide rail. A lumbar spine fixing cylinder 153 having a rail member capable of being seated and controlling the length of the piston rod with an electrical signal;

The body is fixed to the lower surface of the middle bed part 130, and the piston rod of the other side is connected to the lower surface of the upper bed part 120. A cervical spine fixing cylinder 154 controllable with this electrical signal;

At this time, the control unit compares the patient's cervical partial weight and the weight value measured by the load cell, and stops the traction drive motor 151 and periodically changes the moving distance when the weight value measured by the load cell comes within a predetermined error with the cervical partial weight of the patient. Controls the traction drive motor to slide forward and backward.

As shown in Figure 5, when the device of the present invention tows the patient's lumbar spine, the control unit receives the weight value of the pressure sensor in the lumbar direction and moves the upper bed portion 120 forward to pull the patient's lumbar spine. The drive motor 151 is driven.

At this time, the control unit controls the length of the piston rod of the cervical spine fixing cylinder 153 to be contracted and fixed so that the upper bed portion 120 is in close contact with the middle bed portion 130 and fixed, and the length of the piston rod of the lumbar spine fixing cylinder 153 is fixed. The lumbar spine of the patient is towed by controlling the gap between the upper bed portion 120 and the middle bed portion 130 by controlling the flexible movement without fixation.

That is, when the upper bed part 120 moves forward, the control unit fixes the middle bed part 130 in close contact with the upper bed part 120, and the upper bed part 120 and the middle bed part 130 move forward together. and tow the patient's cervical spine.

At this time, the control unit compares the patient's lumbar partial weight with the weight value measured by the load cell, stops the traction drive motor 151, and periodically adjusts the moving distance when the weight value measured by the load cell comes within a predetermined error with the lumbar partial weight of the patient. Controls the traction drive motor to slide forward and backward.

Although the embodiments of the present invention have been described with reference to the above and accompanying drawings, those skilled in the art to which the present invention pertains can implement the present invention in other specific forms without changing the technical spirit or essential features. You will understand that there is Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive.
