When not being treated, the traction table 6 is made into a chair, making it easier for the patient to get on and off the device and moving the traction table 6 backward during treatment. This is an example of a traction device in which a patient is placed in a substantially horizontal supine position (traction position) and lumbar traction therapy is performed.
The apparatus includes a base 1, a traction treatment table 6, a tilting mechanism unit 3, and a lumbar traction mechanism unit 7.
The traction treatment table 6 is rotatably connected to the base 1 via an axis O in the transverse direction of the traction treatment table 6.

Lapping the lumbar vertebra with the interval of the part 5 close (for example, Patent Document 1).

As described above, the traction device includes the cervical traction device and the lumbar traction device, and several drive methods have been disclosed, but the reasons for the device function, installation space and patient pain reduction, labor saving, etc. Therefore, at present, the cervical traction device is often used as the device shown in FIG. 5, and the lumbar traction device is used as the device shown in FIG.
In addition, since the diseases of the cervical vertebra and the lumbar vertebra are almost the same, the two models shown in FIG. 5 and FIG.

However, the introduction of the two models requires a lot of cost and space. In some cases, only one device is used, and the other is not used, and there is a problem in terms of effective use of the device. .
Therefore, a device capable of two traction treatments for the cervical vertebra and the lumbar vertebra with one traction treatment table as shown in FIG. 9 has been put into practical use.

JP2006-87853

In the traction device, before treatment, a traction condition suitable for the patient is set and treatment is started. That is, the treatment conditions of the previous treatment remain before treatment. Therefore, in the traction device that can perform two treatments of cervical traction and lumbar traction with one traction device as shown in Fig. 9, if there is an operation forgotten or incorrect operation, lumbar traction and cervical traction are mistaken, For example, there is a possibility that cervical traction is performed under lumbar traction treatment conditions, or conversely, lumbar traction treatment is performed under cervical traction treatment conditions.
The traction force for lumbar traction is 1/3 to 1/2 of the body weight, and the traction force for cervical traction is around 10 kgf.
Therefore, treatment conditions for lumbar traction When cervical traction is performed, excessive force is applied to the cervical vertebra, which is extremely dangerous. Conversely, if lumbar traction is performed under the cervical traction method, the therapeutic effect cannot be obtained due to insufficient traction.

In addition, since cervical traction is performed with a small traction force of about 10 kgf, an error in the traction force greatly affects the treatment.
The apparatus of FIG. 9 fixes the head and moves the traction treatment table 6 to generate traction force. However, since the weight of the traction treatment table 6 on which the patient is placed is large, the friction force is large. Further, this frictional force varies greatly depending on the patient's physique difference. Moreover, the frictional force varies greatly depending on the angle of the traction treatment table 6, that is, the angle of the cervical traction position. Furthermore, during use, the frictional force fluctuates due to wear of the mechanism.
Due to such factors, the method of moving the traction treatment table 6 is affected by friction, and the traction force applied to the cervical spine is inaccurate, making it difficult to perform effective treatment and also dangerous.
An object of the present invention is to solve such a problem and to provide a traction device capable of performing safe and effective traction treatment.

Since the present invention is provided with independent lumbar traction means and cervical traction means, lumbar traction and cervical traction can be performed with a single device.
Further, unlike the apparatus of FIG. 9, the lumbar traction means and the cervical traction means are independent. For this reason, each treatment condition can be set and each traction treatment can be performed accurately. In addition, unlike the apparatus of FIG. 9, the patient's weight, the angle of the traction treatment table, the change in friction of the traction mechanism part over time, etc. are affected by friction, but the present invention is not affected by fluctuations in traction force due to friction, Accurate treatment can be performed with the traction conditions set at all times.
In addition, when an operation is applied to either the lumbar traction means or the cervical traction means, it is identified which operation has been applied, the traction means selected is operated, and the traction treatment is performed. The means should not be used. For this reason, it is possible to avoid the risk of performing treatment by mistaking lumbar traction and cervical traction.

The wire take-up drum 12 is rotatable, provided with a spring, and disconnected from the motor 11 with a clutch. The wire 13 can be pulled out freely, and when released, the wire take-up drum 12 is rotated with the spring, and the wire 13 is wound up. As long as the wire can transmit the traction force, a belt may be used as in the embodiment of FIG.
Further, the operation panel of the apparatus is provided with an input unit for inputting traction conditions such as traction force and traction time, a display unit for displaying the treatment status, and the like. Furthermore, a control unit for controlling the entire apparatus is provided.

FIG. 2 shows a configuration example of the end portion of the wire 13.
As shown in FIG. 2A, a wire member B to which the neck brace Sn can be attached and detached is provided at the end of the wire 13.
When the cervical traction means is not used, the wire 13 is wound up by the wire winding drum 12 as described above.
However, in order to prevent the entire wire 13 from being wound around the wire take-up drum 12, as shown in FIG. I have to.

The light is received by the light receiving part r through the part of the part that has been hollowed out, and it is determined that no operation has been applied to the cervical traction means.
In this state, it is a state waiting for any one of the lumbar traction means and the cervical traction means to be operated.

Prior to treatment, the traction table is placed in a sitting position, the patient is seated there, the neck brace Sn is connected to the wire 13, the wire is pulled out and attached to the patient. At this time, as shown in FIG. 3B, the light emitted from the light emitting portion L is reflected by the wire 13 and cannot be detected by the light receiving portion r, and it is determined that an operation has been applied to the cervical traction means (operation detecting means). . In this embodiment, the operation detection means includes a light emitting unit L and a light receiving unit r.
When it is detected that the operation is detected by the operation detection unit, the control unit checks the output of the light receiving unit, and it is determined from the output of the light receiving unit r of the cervical vertebra pulling unit that the cervical spine pulling unit is operated (operation side determination unit). ).
If it is determined that the cervical traction means has been operated, the cervical traction means is selected by the selection-side traction execution means so that the lumbar traction is not activated.
In this way, cervical traction and lumbar traction are not mixed and used, and safe and effective traction treatment can be performed.

When cervical traction is selected, standard treatment conditions for cervical traction or treatment conditions for the previous cervical traction are selected, displayed, and wait for input from the input unit.
When changing to treatment conditions suitable for the patient, traction conditions such as traction force Fn, treatment time, duration, and rest time are input from the input unit.

When the treatment is started, the tilting mechanism unit 3 is actuated, and the traction treatment table 6 is tilted backward to the cervical vertebral position tilted backward by a predetermined angle.
After that, the clutch is driven to connect the motor 11 and the wire take-up drum 12. Although not shown in the figure, the current traction force is monitored by the traction force detection unit, and the motor 11 is compared with the set traction force. Then, the wire winding drum 12 is operated to wind the wire 13, the head is pulled through the neck orthosis Sn, and a predetermined traction force Fn is applied to the cervical spine.
Therefore, traction can be performed with a traction force that is more accurate than the conventional apparatus of FIG.
The cervical vertebral pulling position can be set at any angle depending on the patient's condition and other requirements, such as the so-called semi-sitting position tilted about 45 degrees while the sitting position (not tilted), and the pulling position tilted about 90 degrees to the nearly horizontal supine position. You can do it.
The traction mechanism is a conventional system using a wire as shown in FIG. 5, but any system such as a system using a linear actuator shown in FIG. 6 may be used.
The cervical traction means is configured by providing the control means for executing the cervical traction therapy as described above.

In this embodiment, an optical sensor is provided at the tip of the bar b to monitor whether the wire has been drawn. That is, in this example, the optical sensor is a traction unit monitor, and the traction unit monitor is provided in the cervical vertebra traction unit.
In this embodiment, an optical sensor having a light emitting part and a light receiving part is provided, and the irradiation light from the light emitting part is emitted toward the wire 3. When the wire 3 is not pulled out, as shown in FIG. 2 (A), the irradiation light is prevented from hitting the wire so that the irradiation light is reflected and is not detected by the light receiving unit. When the wire 3 is pulled out, as shown in FIG. 2 (B), the irradiated light hits the wire and is reflected, and the irradiated light is reflected and detected by the light receiving unit.
However, the present invention is not limited to the optical sensor, and any other sensor such as an ultrasonic wave, radio wave, magnetism, etc. may be used, and any method such as a method of viewing a transmitted wave as well as a reflected wave is used. The force applied to the bar b, the wire, the neck brace, and the like when the wire is pulled out may be monitored. Since the wire take-up drum 2 rotates when the wire is pulled out, this rotation may be monitored.

As described above, when the wire of the cervical traction unit is pulled out, it is determined that an operation has been applied to the cervical traction unit, cervical traction treatment is selected, and the cervical traction treatment program is executed. When the cervical traction program is executed, lumbar traction operation is not accepted, so that lumbar traction treatment is prohibited and safe cervical traction can be performed.
In cervical traction, the traction force is about several to tens of kgf, the treatment time is 10 to 15 minutes, the duration is 10 to 20 seconds, and the rest time is about 5 to 10 seconds. For example, the traction force is 10 kgf, the treatment time is 10 minutes, the duration is 15 seconds, the rest time is about 5 seconds, and most patients are treated under the same treatment conditions.

In lumbar traction, a lumbar orthosis is attached, so the operation detection means can be obtained by monitoring the attachment state of the lumbar orthosis.
If it is determined that the lumbar traction means is operated by the operation detection means, it is determined that the lumbar traction means is selected by the operation side determination means, and the lumbar traction is executed by the selection side traction execution means, as in the above cervical traction To do.
In lumbar traction, the traction force is about 1/3 to 1/2 of the body weight, the treatment time is 10 to 15 minutes, the duration is 10 to 20 seconds, and the rest time is about 5 to 10 seconds. . However, in general, standard treatment conditions such as a traction force of 25 kgf, a treatment time of 10 minutes, a duration of 15 seconds, and a rest time of about 5 seconds are determined, and most patients are treated under the same treatment conditions. There are many things.

The operation panel, input unit, display unit, and control unit may be shared by the lumbar traction means and the cervical traction means. In this case, an operation panel having an input unit and a display unit is provided with a switch for switching between the lumbar traction means and the cervical traction means so that either one can be selected and used.
When either the lumbar traction means or the cervical traction means is selected with the changeover switch, the treatment condition stored in the treatment condition storage unit of the selected traction means is displayed on the display. If it is desired to change the treatment condition, it may be input again from the input unit. The treatment condition storage unit may store standard treatment conditions so that the treatment conditions can be changed. If standard traction force is used, unexpected traction force does not act, and safe and effective traction can be achieved. Further, if the range in which the traction force can be input is determined, an excessive or excessive traction force is not input. Therefore, for example, in cervical traction, treatment conditions for lumbar traction cannot be set, and thus the risk can be reduced.
If such a technique is additionally used for the operation detection means of the present invention, the safety can be doubled.

Before treatment, it is in a state of waiting for any one of the operation detection means to be operated.
When the patient is placed on the device, the cervical traction wire 13 is pulled out and the cervical spine is attached, it is determined that cervical traction is to be performed, the treatment conditions are prepared, and cervical traction treatment can be executed.
When the patient rests on the device and wears the lumbar orthosis b, it is determined that lumbar traction is to be performed, the treatment conditions are prepared, and lumbar traction treatment can be executed.
Thus, the traction treatment on the operated side can be performed under the treatment conditions.
For this reason, it is possible to prevent medical errors without losing lumbar traction and cervical traction.
In addition, since the treatment conditions prepared at this time are the standard traction treatment conditions or the traction treatment conditions used in the previous treatment on the same side, since the traction force is not extremely large or small, the risk is low, High therapeutic effect is also obtained.
Furthermore, since the cervical vertebra is also pulled by a dedicated pulling means, unlike the conventional apparatus shown in FIG. 9, the frictional force does not become a problem and an appropriate pulling force can be applied. For this reason, a high therapeutic effect can be obtained reliably.
For this reason, medical efficiency can also be improved.
As described above, two traction treatments for the cervical vertebra and the lumbar vertebra can be effectively, safely and efficiently performed with one device, and the cost and space saving effects can be obtained. .
