Description

  The present invention relates to a traction treatment apparatus having a cervical vertebra and lumbar traction mode.

  Conventionally, as shown in Patent Document 1, the side or neck of the patient's body is suspended by the upper body suspension 2 and the seat 3 is lowered in this state, and the load W received by the seat 3 reaches a predetermined value. There is known a health treatment device for treating the lumbar vertebrae and the cervical vertebra so that the lowering of the seat portion 3 automatically stops when the seat portion 3 descends.

  The health treatment device of Patent Document 1 is configured to increase or decrease the predetermined value of the load W depending on the application (purpose of use). However, it is assumed that the load W for lumbar traction is set by mistake, but an appropriate load value is set for this device according to the traction site, or it is set incorrectly. No detection means is provided for determining and detecting whether or not.

  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), it is not possible to continue cervical traction while setting the lumbar traction force value. There is a high risk of damaging the neck by overloading the neck, and it is extremely dangerous. It is necessary to detect an incorrect setting of the load value (traction value) at an earlier stage. It was hoped for.

Thus, the backrest seat portion 10 is configured to be movable to the backrest seat rail 11.

  At the center of the upper end of the traction frame 22 is provided a cervical vertebra support device 37 that supports a cervical vertebra support device 36 that is attached to the patient's head when performing cervical traction therapy. The cervical vertebra support device 37 includes a cervical vertebra arm 38, a pulley. 40, 40, a cord 42, a winding mechanism 43, a cervical vertebral load cell 55 as a cervical traction force detecting means 51, and the like. The cervical spine load cell 55 detects the value of the traction force applied to the patient's cervical spine via the cervical spine 36 when the cervical spine is pulled.

  The base of the cervical vertebra arm 38 is fixed to the upper end of the center of the traction frame 22 so as to extend from the back of the back seat 10 to the vicinity of the front of the patient's head. In the cervical vertebra arm 38, pulleys 40, 40 for guiding the feeding and winding of the belt-like cord body 42 are disposed at the front and rear ends of the cervical vertebra arm 38, and the cord body is located at the back of the cervical vertebra arm 38. A winding mechanism 43 for winding 42 is fixed to the traction frame 22 via a cervical spine load cell 55. In addition, the length of the cervical spine arm 38 can be adjusted by operating the adjustment knob 20.

  One end of the cable body 42 is fixed to the winding drum 44 of the winding mechanism 43, and the other end is configured to be able to hang the cervical traction hanger 41. As shown in FIG. 1, a cervical spine orthosis 36 attached to the patient's head is hooked on the cervical traction hanger 41.

  As shown in FIG. 3, the take-up mechanism unit 43 has a take-up drum 44 mounted around a take-up drum shaft 48, and is wound in one end of the take-up drum shaft 48 in a direction in which the rope 42 is always taken up. A mainspring spring 45 for urging the drum 44 is provided, and a winding fixing mechanism 46 (specifically, an electromagnetic brake 47) for fixing the rotation of the winding drum 44 during cervical traction treatment is provided at the other end. Yes. During the cervical traction operation, the take-up drum 44 is basically unrotatable by the take-up fixing mechanism 46, but the cord body 42 is used to attach the cervical spine brace 36 to the patient during cervical traction treatment. When the cervical traction force detection means 51 detects this with a force of a certain level or more, the fixing function by the winding fixing mechanism 46 is released, and the cord 42 can be fed and wound.

  As shown in FIGS. 1 and 2, an electric actuator 17 as lumbar traction means 27 and lumbar traction force detection that enables the lower body sheet 4 to reciprocate along the seat rail 7 are located at the back side position of the lower body seat 4. Components such as a lumbar load cell 30 as means 28 are provided.

  One end of a lumbar load cell 30 for detecting the thrust value of the electric actuator 17 is fixed to the traction frame 22, and the bottom of the cylinder portion 17 a of the electric actuator 17 is pivotally attached to the other end of the lumbar load cell 30. The rod portion 17 b of the electric actuator 17 extends in the front-rear direction substantially parallel to the extending direction of the seat rail 7, and the tip portion is pivotally attached to the seat support member 8. Accordingly, when the rod portion 17b is expanded and contracted, the seat roller 9 rolls along the inner periphery of the seat rail 7 and the seat portion 5 smoothly reciprocates.

  In addition, the electric actuator 17 attaches the cervical spine brace 36 to the patient's head, causes the take-up fixing mechanism 46 to function and disables the take-up drum 44 from rotating. 4, the lower body sheet portion 4 is also moved in a direction in which the lower back brace 29 and the cervical vertebra 36 are separated from each other, thereby also serving as a cervical traction means 50 for performing cervical traction treatment.

  The load cell 30 for the lumbar spine is mounted when the lower body seat portion 4 is moved away from the backrest seat portion 10 with the waist orthosis 29 attached to the patient's waist and the armpit 32 sandwiched between the armpits. The lumbar traction force acting on the patient's lumbar region via the brace 29 is detected. Further, the lumbar load cell 30 detects the weight value of the patient sitting on the chair 3, and further raises the armpit 32 to a position where it abuts the armpit, and supports the armpit of the patient with the armpit 32. In addition, the amount of change in the weight value is detected as a pressing force applied to the armpit device 32.

  A side brace position control device 60 used for lumbar traction treatment is provided on the back surface of the backrest seat portion 10. The side brace position control device 60 is a pair of left and right side arms 33 and a side that rotates the side arms 33. An electric actuator 59 as the arm drive unit 61 and a guide unit 62 that guides and restricts the rotation of the side arm 33 are configured. A side brace 32 that attaches to the side of the patient and supports the side part is attached to the tip of the side arm 33. The base of the side arm 33 is pivotally attached to the side arm support member 35. Further, a pin 64 projects from the side arm 33 toward the backrest seat portion 10, and the pin 64 is inserted into the elongated hole 16 formed in the side arm support member 35.

  As shown in FIG. 2, the pulling frame 22 is provided with a guide portion 62 extending toward the side arm 33. The urging member 14 is provided in the guide portion 62, and the side brace 32 is moved to an appropriate range in the vicinity of the patient's flank (specifically, the space between the left and right side brace 32 is about 350 mm), so that the patient However, the side arm 33 is elastically supported so that the side brace 32 can be pulled to the side and mounted at an optimal position immediately after the transfer.

  The side arm support member 35 is located on the back surface of the backrest seat portion 10, and a plurality of rolling rollers 18 are rotatably provided on the side surface of the side arm support member 35, and the side arm support member 35 is a side brace. It is movable along the rail 34.

  The tip of the rod portion 59 b of the electric actuator 59 is pivotally attached to the side arm support member 35, and the cylinder portion 59 a is pivotally attached to the traction frame 22. When the rod portion 59b is expanded and contracted, the side arm 33 moves along the side orthosis rail 34 and rotates in the surface direction of the backrest seat portion 10.

  As shown in FIG. 2, the traction therapy apparatus 1 is provided with an operation panel portion 26 that is supported so as to be adjustable in angle with respect to a support arm 31 protruding rightward from an upper position on the right side surface of the traction frame 22. As shown in FIG. 4, the operation panel unit 26 directly receives the traction mode switching setting unit 39 as the mode selection means 57 for selecting either the lumbar traction mode or the cervical traction mode, the cervical traction force value, and the lumbar traction force value. A traction force setting unit 49 for inputting and setting, and a treatment time setting unit 56 for setting a traction treatment time are provided. In general, a value in the range of 3 to 25 kg as the cervical traction force value and a value in the range of 5 to 60 kg as the lumbar traction force value are appropriately set according to the weight and symptoms of the patient. In addition, although illustration and detailed explanation are omitted, various switches such as a duration setting unit for setting a traction duration, a pause time setting unit for setting a traction pause time, and a traction treatment start / stop switch are also provided on the operation panel unit. 26.

The control unit 25 of the traction therapy apparatus 1 includes a cervical traction force storage unit 53 and a lumbar lumbar traction force storage unit 54 that store the cervical traction force value and the lumbar traction force value input and set by the traction force setting unit 49, respectively. The traction force value stored in the unit and the values detected by the lumbar load cell 30 and the cervical load cell 55 are sequentially compared, and the electric actuator 17 (lumbar traction means 27 and cervical traction means 50), electric actuator 59 (side arm) The operation of the drive unit 61) and the like is controlled.
The control unit 25 has a function of detecting whether or not a mode different from the traction mode desired by the user or the like is erroneously selected, and whether or not the traction operation is started in the erroneously selected mode. . Specifically, where the traction treatment should be performed in the cervical traction mode, the user or the like erroneously operates the traction mode switching setting unit 39 to select the lumbar traction mode and start the traction treatment, This is the case where the cervical traction mode is selected and the traction treatment is started where traction treatment should be performed in the lumbar traction mode.

  Therefore, when the lumbar traction operation is being performed by the comparison determination unit 58 of the control unit 25, the detection value detected by the cervical vertebra load cell 55 is constantly monitored as the cervical traction force value, and this cervical traction force value is set. When the comparison / determination unit 58 recognizes that the threshold value (for example, 3 kg) has been reached, it is determined that the lumbar traction mode has been erroneously selected and the lumbar traction operation has been started, and the lumbar traction operation has been started. Stop. This is because the cervical traction force value is not detected by the cervical spine load cell 55 because the cervical spine brace 36 is not attached to the patient's head when the lumbar traction operation is performed.

In addition, when the cervical traction operation is being performed, the comparison / determination unit 58 constantly monitors the detection value detected by the lumbar vertebra load cell 30 as the lumbar traction force value. When the comparison / determination unit 58 recognizes that the value obtained by subtracting the cervical traction force value detected in step S <b> 30 has reached a set threshold (e.g., 30 kg), the cervical traction mode is selected by mistake in selecting the lumbar traction mode. It is determined that the movement has started, and the cervical spine traction movement is stopped. When cervical spine traction is started with the armpit 32 sandwiched between the armpits, the armpit of the patient is placed by the armpit brace 32 before the cervical traction force value is detected by the cervical spine load cell 55 (before the cervical vertebra is pulled). In this supported state, the rod portion 17b of the electric actuator 17 continues to expand, and an excessive traction force is applied to the lumbar spine, so that a very dangerous situation is assumed. This is to prevent this.
When a traction operation in the above-described incorrect traction mode is detected, a notification sound is generated by a speaker or buzzer (not shown) provided in the traction treatment device 1 before the traction operation is stopped, and the user or the like To inform that the traction mode is not properly selected. In FIG. 1, 63 is a seat cover attached to the seat 5, and 15 is an elbow rest fixed to the traction frame 22.

  Hereinafter, the operation of the traction therapy apparatus 1 will be described. First, the operation for traction treatment of the patient's cervical spine will be described. A user such as a doctor operates the traction mode switching setting unit 39 of the operation panel unit 26 to select the cervical vertebra traction mode, then sets the cervical traction force value in the traction force setting unit 49, and the treatment time in the treatment time setting unit 56. Set the input. In the cervical traction treatment, the armpit 32 is not used because it is not sandwiched between the patient's armpits.

  A waist brace 29 is wound around the patient's waist and the distal ends are overlapped and joined together, and the patient is fixedly held on the lower body sheet portion 4. A cervical spine hanger 41 is hooked on the distal end of the cord body 42, and the cervical spine orthosis 36 is suspended from the cervical spine hanger 41. At this time, the take-up fixing mechanism 46 is acting and the take-up drum 44 cannot be rotated. However, in order to attach the cervical spine brace 36 to the patient, the cord body 42 is pulled with a force of a certain level or more. When the detection means 51 detects this, the fixing of the winding fixing mechanism 46 is released, and the rope body 42 is in a state where it can be extended. The cord 42 is pulled out and the cervical spine brace 36 is attached to the patient's head. The length of the cervical vertebra arm 38 is appropriately adjusted by operating the adjustment knob 20 so that the elevation angle formed by the surface of the backrest seat portion 10 and the extended surface of the cord 42 is approximately 30 °. The take-up drum 44 is maintained in a rotatable state until a reclining operation of the chair portion 3 to be described later is completed.

  After completing the preparation for cervical traction therapy, the user confirms safety and then operates a traction therapy start switch (not shown) to start traction therapy. Prior to the reclining operation of the chair part 3, the electric actuator 17 is first contracted and the lower body seat part 4 is moved from the transfer position to the pulling start position, and then the rod part 2b of the electric actuator 2 is contracted and the entire chair part 3 is moved. Surrender. When the chair part 3 reaches a predetermined lying position, the reclining operation stops.

  When the reclining operation stops at the predetermined lying position, the electromagnetic brake 47 functions to automatically fix the rotation of the winding drum 44, and the cable body 42 cannot be paid out and wound. Subsequently, the control unit 25 extends the rod portion 17b of the electric actuator 17 and moves the lower body seat portion 4 along the seat rail 7 in a direction away from the backrest seat portion 10 to thereby interlace the cervical spine 36. The traction force is applied to the patient's neck.

  At this time, the cervical traction force value detected by the cervical vertebra load cell 55 and the lumbar traction force value detected by the lumbar load cell 30 are input to the control unit 25 (S1 in FIG. 5). Whether the value obtained by subtracting the cervical traction force value from the value exceeds the set threshold (30 kg) is monitored (S2). When the cervical vertebra orthosis 36 is attached to the patient's head and cervical vertebra traction treatment is performed in the cervical traction mode, the value obtained by subtracting the cervical traction force value from the lumbar traction force value does not exceed the set threshold value. The comparison determination unit 58 determines that the cervical traction mode is properly selected and the cervical traction operation is properly performed (S3), and continues the cervical traction operation (S4).

  The controller 25 sequentially compares the cervical traction force value detected by the cervical spine load cell 55 and the set cervical traction force value input and set by the traction force setting unit 49, and the cervical traction force value detected by the cervical spine load cell 55 is set as the set cervical traction force. When the cervical 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 lower body seat portion 4 from the traction start position to the traction position. Then, the lower body sheet 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. During the first relaxing operation, the lower body seat portion 4 is moved back to the pulling start position, the function of the electromagnetic brake 47 is released, and the mainspring spring 45 is wound around the winding drum so that the rope 42 It is designed to get rid of.

  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, the lower body seat portion 4 is returned to the pulling start position, and the electronic brake 47 is moved. After the function is released and the winding drum 44 is allowed to rotate, the chair portion 3 is reclined in the standing direction to complete the cervical traction operation.

  When the cervical traction force value exceeds the set threshold value, the lumbar traction mode is erroneously selected in the cervical traction mode and the lumbar traction mode is selected, that is, the lumbar traction is performed with the cervical spine brace 36 attached. After the mode is selected and the comparison / determination unit 58 determines that the lumbar traction is started (S11 in FIG. 6), the control unit 25 announces to the user or the patient by voice that the lumbar traction mode is erroneously selected. Then, the operation of the electric actuator 17 is stopped to stop the lumbar traction operation (S12). After stopping the lumbar traction operation, the chair portion 3 is reclined in the upright direction as described above to finish the lumbar traction.

  Next, the operation | movement at the time of traction treatment of a patient's lumbar vertebra is demonstrated. The user operates the traction mode switching setting unit 39 of the operation panel unit 26 to select the lumbar traction mode, and then inputs and sets the lumbar traction force value in the traction force setting unit 49 and the treatment time in the treatment time setting unit 56. . After the setting is completed, the patient is transferred to the chair portion 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.

  After the waist brace 29 is wrapped around the patient's waist and fixed to the lower body seat portion 4, the rod portion 2b of the electric actuator 2 is contracted to recline the chair portion 3 in the lying down direction in the same manner as the operation of cervical traction therapy. . 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 portion 17b of the electric actuator 17 is extended, and the lower body seat portion 4 is moved along the seat rail 7 in a direction away from the backrest seat portion 10 to exert a traction force on the waist of the patient via the waist brace 29. Let
At this time, the cervical traction force value detected by the cervical vertebra load cell 55 and the lumbar traction force value detected by the lumbar load cell 30 are input to the control unit 25 (S7 in FIG. 6). It is monitored whether the value exceeds the set threshold (3 kg) (S8). When the lumbar traction mode is properly selected and the lumbar traction treatment is performed, the cervical vertebral traction force value is not detected in the cervical spine load cell 55 because the cervical spine brace 36 is not attached to the patient's head. Does not exceed the set threshold. At this time, the comparison determination unit 58 determines that the lumbar traction mode is properly selected and the lumbar traction operation is properly performed (S9), and continues the lumbar traction operation (S10).

  The control unit 25 sequentially compares the lumbar traction force value detected by the lumbar load cell 30 and the lumbar traction force value input and set by the traction force setting unit 49, and the lumbar traction force value detected by the lumbar load cell 30 is set as the set lumbar traction force value. When 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 lower body seat portion 4 is moved back 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 portion 3 is reclined in the standing direction to complete the lumbar traction operation.

  When the value obtained by subtracting the cervical traction force value from the lumbar traction force value exceeds the set threshold, the cervical traction mode is mistakenly selected to perform the traction operation in the lumbar traction mode, that is, the traction operation is started. The comparison determination unit 58 determines that the cervical vertebra traction mode is selected and the cervical vertebra traction is started with the pin 32 sandwiched between the armpits (S5 in FIG. 5), and the control unit 25 indicates that the cervical vertebra traction mode is erroneously selected. After the voice is announced to the user and patient, the operation of the electric actuator 17 is stopped and the cervical traction operation is stopped (S6). After stopping the cervical traction operation, the chair portion 3 is reclined in the upright direction as described above to complete the cervical traction operation.

  Next, a second embodiment will be described with reference to FIGS. 4, 7 and 8. In the first embodiment, when the traction mode is selected by mistake, the lumbar traction operation is stopped after the user or patient is notified by voice that the traction mode is selected by mistake (FIG. 6). S12) or the cervical traction operation is stopped (S6 in FIG. 5). However, the second embodiment does not employ this configuration, and the traction mode is erroneously selected. After announcing to the user or patient that the change is to be made, the traction mode that has been selected incorrectly is automatically changed to an appropriate traction mode desired by the patient, and the traction operation is resumed.

In S13 to S14 of FIG. 7, as a result of erroneously selecting the lumbar traction mode and starting the lumbar traction operation by selecting the cervical traction mode, the comparison determination unit 58 determines that the traction mode is erroneously selected. If it is made (S15), since the lumbar traction mode has been selected by mistake, the user or patient is notified by voice that the lumbar traction mode will be changed. Subsequently, the control unit 25 stops the lumbar traction operation and moves the lower body seat unit 4 back to the traction start position. Thereafter, the control unit 25 automatically changes the setting of the traction mode switching setting unit 39 from the lumbar traction mode to the cervical traction mode (S16). When the lumbar traction mode is automatically changed to the cervical traction mode, the cervical traction force value stored in the cervical traction force storage unit 53 is automatically set as the traction force value, and the cervical traction operation is resumed (S17).
In addition, after the automatic change to the cervical traction mode, the user may manually input and set the cervical traction force value directly to the traction force setting unit 49 and then restart the cervical traction operation.

Further, in S20 to S21 of FIG. 8, as a result of erroneously selecting the lumbar traction mode and selecting the cervical traction mode and starting the cervical traction operation, the comparison / determination unit 58 selects the traction mode incorrectly. When the determination is made (S22), since the cervical traction mode is erroneously selected, the user and the patient are notified by voice that the mode is changed to the lumbar traction mode. Subsequently, the control unit 25 stops the cervical vertebra pulling operation and moves the lower body sheet unit 4 back to the pulling start position. Thereafter, the control unit 25 automatically changes the setting of the traction mode switching setting unit 39 from the cervical traction mode to the lumbar traction mode (S23). When the cervical traction mode is automatically changed to the lumbar traction mode, the lumbar traction force value stored in the lumbar traction force storage unit 53 is automatically set as the traction force value, and the lumbar traction operation is resumed (S24).
Similarly to the above, after automatically changing to the lumbar traction mode, the user may manually input the lumbar traction force value directly to the traction force setting unit 49 and then resume the lumbar traction operation.

  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. For example, in S2 of FIG. 5 and S21 of FIG. 8, the cervical traction force value is subtracted from the lumbar traction force value, and the comparison determination unit 58 determines that the traction mode is erroneously selected when this value exceeds the set threshold value. Although the control example has been described, conversely, the lumbar traction force value may be subtracted from the cervical traction force value, and it may be determined that the traction mode is erroneously selected when the absolute value of this value exceeds the set threshold value. In the above-described embodiment, the cervical traction means 50 is configured to fix the patient's head with the cervical vertebra brace 36 and move the lower body seat portion 4 using the lumbar vertebra traction means 27. However, the configuration is not limited thereto. The object of the present invention can also be achieved by performing cervical traction by directly winding the cord body 42 from which the cervical spine orthosis 36 is suspended by the winding mechanism 43.

  The present invention can be applied to a traction treatment apparatus having a cervical vertebra and a lumbar traction mode, and has high industrial applicability.
