Description

  The present invention relates to a traction treatment device capable of traction treatment of a cervical vertebra part and a lumbar vertebra part.

  Conventionally, as shown in Patent Document 1, a fixed support frame 1, an upper body suspension 2 attached to an upwardly extending portion of the fixed support frame 1 to suspend a side part or a neck of the upper body of the body, and the upper body And a seat part 3 provided on the fixed support frame 1 so as to be able to move up and down so that the upper body is lowered in a state in which the upper body is suspended by the hanger 2. The lumbar region and the cervical vertebra are automatically suspended when the seat portion 3 is lowered and the load W received by the seat portion 3 is lowered to a predetermined value. 2. Description of the Related Art Health treatment devices that perform site treatment are known. According to this health treatment device, it is possible to treat both the lumbar region and the cervical region with a single device.

  However, the health treatment device of Patent Document 1 is configured to increase or decrease the predetermined value of the load W in accordance with the towed region. It is assumed that the setting operation is wrong and the load W for lumbar traction is set.

  In particular, in cervical traction therapy in which traction is performed by setting a smaller load (cervical traction force value) than the load value for lumbar traction (lumbar traction force value), traction of the cervical vertebra part is continued with the lumbar traction force value set. This is very dangerous because it can cause excessive burden on the cervical vertebrae part and damage to the cervical vertebrae part. However, conventional health treatment equipment has no safety function to prevent such erroneous traction. However, there is a problem in terms of safety, and the improvement has been eagerly desired.

The operation of the lumbar traction means 27 and the cervical traction means 50, the electric actuator 59 (side arm driving unit 61), and the like are controlled.

  In addition, the control unit 25 prevents the undesirable situation that the cervical traction therapy is started in a state in which the user erroneously switches the traction therapy mode and switches from the cervical traction therapy mode to the lumbar traction therapy mode. In order to enable traction therapy to be performed on the cervical vertebrae, the cervical spine device 36 cannot be mounted from the jaw to the left and right occipital region unless the traction therapy mode switching setting unit 39 is switched to the cervical traction therapy mode. The operation of the appliance 36 is regulated and controlled.

  The traction treatment mode switching setting unit 39 is specifically a traction treatment mode switching switch, and each time this switch is manually pressed, the cervical traction traction treatment mode and the lumbar traction treatment mode are switched to each other. The switched treatment mode name is displayed on the operation panel unit 26. The fixing of the winding drum 44 by the winding fixing mechanism 46 described above is released when the traction treatment mode switching setting unit 39 is switched to the cervical vertebra traction treatment mode, and the cord 42 is extended and wound. Is possible.

  After switching to the cervical vertebra traction treatment mode, when traction treatment of the cervical vertebra part is started with the cervical spine brace 36 attached, the electromagnetic brake 47 of the winding fixing mechanism 46 functions and the rotation of the winding drum 44 is automatically performed. It is fixed and the operation of unwinding and winding the cord-like body 42 becomes impossible. On the other hand, when the lumbar traction treatment mode is switched when setting the treatment conditions or during the lumbar traction treatment mode being performed, the electromagnetic brake 47 is also applied to rotate the winding drum 44. It is controlled to be impossible.

  Hereinafter, the operation of the traction therapy apparatus 1 according to the first embodiment will be described. First, the operation for traction treatment of the patient's cervical spine will be described. It is assumed that the traction treatment mode is the lumbar traction treatment mode and the winding drum 44 is fixed by the winding fixing mechanism 46 (S1 in FIG. 5). A user such as a doctor sets various treatment conditions such as a traction treatment mode, a cervical traction force value, and a treatment time on the operation panel unit 26 (S2). Here, the control unit 25 determines whether or not switching to the cervical traction therapy mode is performed in the traction therapy mode switching setting unit 39 (S3), and determines that switching to the cervical traction therapy mode is performed. In this case, the electromagnetic brake 47 is disabled and the winding drum 44 is released (S4).

  A cervical spine brace 36 is suspended from the tip of the cord-like body 42 via a cervical traction hanger 41. In the state of the lumbar traction treatment mode, the winding fixing mechanism 46 is operating and the winding drum 44 cannot be rotated. However, once the cervical vertebra traction treatment mode is switched, the winding drum by the winding fixing mechanism 46 is turned off. The fixing of 44 is released, and the cord 42 can be fed out. The user grasps the cervical traction hanger 41 and the like to pull out the cord-like body 42, and wears the cervical spine device 36 from the patient's jaw to the left and right occipital region (S5).

  Subsequently, the lumbar orthosis 29 is wound around the patient's lumbar region, the tip portions are overlapped and joined, and the patient is fixedly held on the seat 4 (S6). The length of the cervical spine arm 38 is appropriately adjusted by operating the adjustment knob 20 so that the elevation angle formed by the surface of the backrest 10 and the extending surface of the cord-like body 42 is approximately 30 °. The winding drum 44 is maintained in a rotatable state until the reclining operation of the chair-shaped portion 3 described later in the lying down direction is completed. During traction treatment of the cervical vertebra site, the side brace 32 is not used because it is not pinched under the patient's armpit.

  When preparation for traction treatment of the cervical vertebra site is completed, the user confirms safety and then operates traction treatment start switch (not shown) to start traction treatment (S7). Prior to the reclining operation of the chair-shaped portion 3, the electric actuator 17 is first contracted and the seat portion 4 is moved from the transfer position to the pulling start position, and then the rod portion 2 b of the electric actuator 2 is contracted and the chair-shaped portion 3. The whole surrenders. When the chair-shaped part 3 reaches a predetermined lying position, the reclining operation stops.

  When the reclining operation is stopped at the predetermined lying position, the electromagnetic brake 47 functions and the rotation of the winding drum 44 is automatically fixed, and the feeding and winding operation of the cord-like body 42 becomes impossible. Subsequently, the control unit 25 extends the rod portion 17b of the electric actuator 17 and moves the seat portion 4 along the seat rail 7 in a direction away from the backrest portion 10 through the cervical spine device 36. Traction is applied to the patient's neck.

  At this time, the cervical traction force value detected by the cervical spine load cell 55 is input to the control unit 25. The control unit 25 sequentially compares the cervical traction force value detected by the cervical load cell 55 and the cervical traction force value input and set by the traction force value setting unit 49, and the cervical traction force value detected by the cervical load cell 55 is set as the cervical spine. Control related to the extension operation of the rod portion 17b of the electric actuator 17 is performed so as to match the traction force value. When the cervical vertebra traction force value matches the set cervical traction force value, the extension operation of the rod portion 17b is stopped.

  When the duration set by the duration setting unit (not shown) ends, the rod portion 17b is contracted by a movement amount that is approximately ½ of the movement amount of the seat portion 4 from the traction start position to the traction position. Then, the seat portion 4 is returned and moved, and at this position, the traction pause operation (= relaxation operation) is performed. In the cervical traction treatment, the traction operation and the pause operation are repeated until the treatment time set by the treatment time setting unit 56 elapses. At the time of the first relaxation operation, the seat portion 4 is moved back to the pulling start position, the function of the electromagnetic brake 47 is released, and the cord body 42 is wound around the winding drum 44 by the mainspring spring 45. It is designed to remove 42 itch.

  When the control unit 25 recognizes that the treatment time has elapsed and the treatment end time has arrived, the contraction operation of the rod portion 17b is controlled to move the seat portion 4 back to the traction start position, and the function of the electromagnetic brake 47 Is released and the rotation of the winding drum 44 is allowed, and then the chair-like portion 3 is reclined in the standing direction to complete the cervical traction operation.

  Next, the operation | movement at the time of traction treatment of a patient's lumbar part will be described. It is assumed that the traction treatment mode is the cervical traction treatment mode. The user operates the traction treatment mode switching setting unit 39 of the operation panel unit 26 to switch to the lumbar traction treatment mode, and then sets the lumbar traction force value in the traction force value setting unit 49 and the treatment time in the treatment time setting unit 56. Set the input.

After the setting is completed, the patient is transferred to the chair-shaped part 3. At this time, the side arm 33 is elastically supported by the biasing member 14 provided in the guide portion 62, and the side brace 32 is in a state in which it can freely move within a predetermined range at the transfer standby position. After sitting, the side brace 32 can be positioned near the flank (= between the trunk and both arms) if necessary.

In the state switched to the lumbar traction treatment mode, the electromagnetic brake 47 of the winding fixing mechanism 46 is actuated so that the winding drum 44 cannot be rotated and the cord 42 cannot be fed out. The brace 36 cannot be worn from the jaw to the left and right occipital region.
Therefore, it is possible to prevent an operation error in which the cervical traction therapy is started in the state where the lumbar traction therapy mode is erroneously switched, and as a result of applying the traction force set in the lumbar traction therapy mode to the patient's cervical vertebra part, There is no risk of overloading the site or damaging or harming the neck, and the patient and the practitioner can use the device with peace of mind. In addition, it is possible to reliably prevent an operation error related to switching of the artificial traction therapy mode.

  After the lumbar orthosis 29 is wrapped around the patient's lumbar region and fixed to the seat 4, the rod portion 2b of the electric actuator 2 is contracted to recline the chair-like portion 3 in the lying down direction in the same manner as the cervical traction treatment. Let The control unit 25 controls the contraction of the rod portion 59b (side arm driving unit 61) of the electric actuator 59 immediately before the start of the lumbar traction treatment, so that the armpit device 32 comes into light contact with the armpit of the patient. 32 is moved up. For example, when the detection value of the lumbar load cell 30 decreases by a predetermined value (about 2 kg), the contraction operation of the rod portion 59b is stopped, and the setting of the side brace 32 is completed.

  The rod part 17b of the electric actuator 17 is extended, and the seat part 4 is moved along the seat part rail 7 in a direction away from the backrest part 10, whereby a traction force is applied to the patient's lumbar part via the lumbar appliance 29. . The lumbar traction force value detected by the lumbar load cell 30 is input to the control unit 25.

  The control unit 25 sequentially compares the lumbar traction force value detected by the lumbar load cell 30 with the lumbar traction force value input and set by the traction force value setting unit 49, and the lumbar traction force value detected by the lumbar load cell 30 is set as the lumbar traction force. When the control relating to the extension operation of the rod portion 17b of the electric actuator 17 is performed so as to match the value and the lumbar traction force value matches the set lumbar traction force value, the extension operation of the rod portion 17b is stopped. Until the treatment time set by the treatment time setting unit 56 elapses, the lumbar traction operation and the pause operation are repeated, and when the control unit 25 recognizes that the treatment end time has arrived, the contraction operation of the rod portion 17b is controlled. Then, the seat portion 4 is returned to the pulling start position, and then the rod portion 59b of the electric actuator 59 is extended to move the side arm 33 downward to return the side brace 32 to the initial position. Thereafter, the chair-like portion 3 is reclined in the standing direction to complete the lumbar traction operation.

  Next, a second embodiment will be described with reference to FIG. In FIG. 6, the same or equivalent components as those in FIG. 4 are denoted by the same reference numerals, and the description of the components is omitted unless particularly required. In the first embodiment, a configuration has been described in which the cervical traction therapy mode and the lumbar traction therapy mode are switched to each other each time one traction therapy mode switching switch (traction therapy mode switching setting unit 39) is pressed. As shown, a cervical traction treatment mode designation switch 66a and a lumbar traction treatment mode designation switch 66b are provided as treatment mode designation means 66, respectively, and a desired traction treatment mode can be designated manually by pressing each switch. Is also possible.

In the first embodiment described above, when switching to the cervical traction therapy mode is performed by the therapy mode switching means 57, the traction force value is set to a value greater than or equal to a predetermined threshold (for example, 25 kg) or greater than the predetermined threshold. The control unit 25 may perform control related to setting of the upper limit value of the traction force value so that the value setting unit 49 cannot set the value. In the second embodiment, when the cervical traction treatment mode designation switch 66a is used to designate the cervical traction treatment mode, it is possible to perform the control related to the same setting of the upper limit value of the traction force value.
By configuring in this way, the safety of the device can be further improved without starting the cervical traction treatment while erroneously setting a traction force value larger than the traction force value normally set during cervical traction treatment.

  Next, a third embodiment will be described with reference to FIGS. In FIG. 7, the same or equivalent components as those in FIGS. 1 to 3 are denoted by the same reference numerals, and the description of the components is omitted unless particularly required. In the embodiment, the traction treatment device 1 includes a traction body unit 68, a wire-like cord body 42 on which a cervical vertebra equipment 36 or a lumbar vertebra equipment 29 is alternatively selected and locked, and a traction A winding mechanism portion 43 (winding drum 44) that is built in the main body unit 68 and allows the other side of the cord-like body 42 to be wound and fed out is provided. The cervical spine device 36, the cord-like body 42, the winding mechanism portion 43 (winding drum 44), etc. constitute the cervical vertebra pulling means 50, and the lumbar spine device 29, the cord-like body 42, the winding mechanism portion 43, etc. are the lumbar spine. The traction means 27 is configured.

  A vertical column 70 is erected in the vertical direction on the upper surface of the pulling main unit 68 formed of a substantially rectangular parallelepiped casing, and a horizontal column 71 is horizontally disposed on the upper end of the vertical column 70 with respect to the vertical column 70. Is provided. A pulley 40 is provided on each of the upper surface of the traction main unit 68 near the base end of the vertical column 70, at the upper part of the vertical column 70, and at the tip of the horizontal column 71, and vertically along the vertical column 70. A movable movable pulley 75 is provided.

  An operation panel unit 26 serving as a treatment condition setting unit 67 is provided on the upper surface of the traction body unit 68. Although not illustrated, the operation panel unit 26 includes a traction force value setting unit and a check treatment time as in the first embodiment. Various setting units such as a setting unit are provided to set treatment conditions.

When performing traction treatment of the cervical vertebra site, as shown by the solid line in FIG. 7, after the cord 42 is introduced along the three pulleys 40 and above the head of the patient, the cervical spine brace 36 is inserted into the patient's head. It is attached to a part from the jaw part to the left and right occipital region, and the cord-like body 42 is wound by the winding mechanism part 43.
On the other hand, when performing traction treatment of the lumbar region, as shown by a two-dot chain line in FIG. 7, a known pulling device is provided along the cable body 42 along the pulley 40 and the movable pulley 75 near the base end of the vertical column 70. After the cord-like body 42 is introduced to the vicinity of the lumbar portion of the patient who is supine on the bed 74, the cord-like body 42 is locked to the lumbar vertebra equipment 29 via the lumbar traction hanger 73, and the cord is rotated by the winding mechanism 43. The state body 42 is wound.

  The winding drum 44 is normally urged in a direction in which the cord-like body 42 is wound by an urging member (not shown), but when the cord-like body 42 is gripped and tension is applied, the winding drum 44 is It is in a so-called free state in which the state body 42 rotates in the feeding direction. Further, the winding drum 44 detects a feeding amount of the cord 42 by detecting a rotation amount in a direction in which the cord 42 is fed from the initial position of the winding drum 44. When the detection unit 72 (for example, an encoder) is interposed and the control unit 25 determines that the traction force value set by the traction force value setting unit 49 is not suitable for traction treatment of a cervical vertebra part where the setting threshold value (for example, 25 kg) is greater than or equal to Controls the operation of the winding drum 44 based on the detection signal of the cord-like body feeding amount detecting means 72 so that the feeding amount of the cord-like body 42 does not exceed a predetermined amount. Do not attach to the part on the left and right occipital region. That is, the control unit 25 fixes the rotation of the winding drum 44 by operating the winding fixing mechanism 46 (electromagnetic brake 47) so that the feeding amount of the cord-like body 42 does not exceed a predetermined amount.

  In general, the feeding amount of the cord-like body 42 when performing traction treatment of the cervical vertebra site is larger than the feeding amount when performing traction treatment of the lumbar region, so that the traction force value equal to or greater than the set threshold value is obtained. When the setting is input, locking of the cord 42 to the lumbar traction hanger 73 (towing the lumbar portion) is possible, but locking of the cord 42 to the cervical traction hanger 41 (cervical portion) It is possible to set the above-mentioned predetermined amount (the feeding amount of the cord-like body 42) such that the pulling of the cord 42 is impossible.

  In addition, once the cervical spine orthosis 36 is attached to the site from the jaw part to the left and right occipital regions, the traction force value that has already been set and input before the attachment may be erroneously changed to a traction force value that is greater than or equal to the set threshold value. The control unit 25 controls the setting input in the tractive force value setting unit 49 so that the control unit 25 does not.

  Next, the operation of the traction treatment device 1 according to the third embodiment will be described by taking as an example a case where traction treatment of the cervical vertebra site is performed. A traction chair 69 is arranged adjacent to the side of the traction main body unit 68 on the extending direction side of the horizontal column 71 and a patient is seated on the traction chair 69. The user sets treatment conditions on the operation panel unit 26 (S8 in FIG. 8). When the tractive force value is set and inputted (S9), the control unit 25 compares this tractive force value with a preset threshold value (for example, 25 kg), and determines whether or not the tractive force value is smaller than the set threshold value ( S10).

When the control unit 25 determines that the tractive force value is smaller than the set threshold value, the cord-like body 42 can be extended to a position where the cervical spine device 36 can be attached to the region from the jaw to the left and right occipital regions. The person holds the cervical traction hanger 41 and the like, feeds the cord-like body 42 and wears the cervical vertebra equipment 36 (S11), and starts traction treatment of the cervical vertebra site (S12).
Although the traction force value may be changed after the cervical spine device 36 is mounted, in this case, the control unit 25 cannot change the traction force value to a setting threshold value or more. There is no possibility that the setting is changed to an excessive traction force value that is not suitable for traction treatment.

In S10, when the control unit 25 determines that the traction force value is equal to or greater than the set threshold value, an attempt is made to perform traction treatment on the cervical spine region, but an incorrect traction force value is set and input by mistake. It is conceivable that the patient is trying to perform traction treatment of the lumbar region.
In the former case, the control unit 25 reads the detection signal from the cord-like body feeding amount detection means 72 (S13), and restricts the rotation of the winding drum 44 so that the feeding amount of the cord-like body 42 does not exceed a predetermined amount. Control (S14). Accordingly, when an excessive traction force value that is not suitable for traction of the cervical vertebra site is erroneously set, even if the user pulls the cord 42, the cord 42 cannot be extended beyond a predetermined amount. The cervical spine brace 36 cannot be attached to the left and right occipital regions from the jaw. The user who recognizes that the cervical spine brace 36 cannot be worn may be set and input again by the traction force value setting unit 49 again.

  On the other hand, when it is going to perform the traction treatment of the latter lumbar part, the lumbar appliance 29 is mounted on the lumbar region (S15) and the traction treatment is started (S12). Further, in S10, the same control (S13 to S15) can be performed even when the control unit 25 determines that the tractive force value is not equal to or greater than the set threshold value and is larger than the set threshold value. After mounting, the control unit 25 can control the traction force value so that the traction force value cannot be changed to a traction force value larger than the set threshold value.

  Moreover, it goes without saying that the present invention is not limited to the above-described embodiments, and can be appropriately changed without departing from the spirit of the present invention. In the first and second embodiments, the configuration example of performing the cervical traction therapy and the lumbar traction therapy by moving the seat part 4 in the direction away from the backrest part 10 as a basic configuration of the traction therapy apparatus 1 has been described. On the contrary, it is possible to adopt a configuration in which the backrest portion 10 is moved in a direction away from the seat portion 4 to perform both traction treatments of the cervical vertebra part and the lumbar part.

  In the third embodiment, the cervical spine and the lumbar spine are selectively selected and locked to one cord-like body, and the cord-like body is wound by the winding mechanism portion to thereby cervical vertebra site. Alternatively, the configuration example of the traction treatment device for traction treatment of the lumbar region has been described. However, another traction means (winding mechanism, cord, etc.) is provided in the traction body unit, and the cervical vertebra region of one patient is already installed. Of course, the present invention can also be applied to a traction treatment apparatus that can simultaneously perform traction treatment on a lumbar region of one patient. In this case, it is not certain which of the two traction means will be used for cervical traction, depending on the patient's usage and usage conditions, and in some cases there is a risk of starting cervical traction therapy with incorrect settings. However, this danger can be avoided by applying the present invention, which is preferable.

  Further, the cervical spine device 36 is not limited to the configuration shown in the drawings, and may be any configuration as long as traction treatment of the cervical vertebra site can be performed. Any detection means may be used as long as the amount of rotation of the winding drum can be detected by parameters such as the number of rotations and angular velocity and the amount of feeding of the cord-like body can be controlled.

  The present invention can be applied to a traction treatment device capable of traction treatment of a cervical vertebra part and a lumbar vertebra part, and has high industrial applicability.
