[0002] Otolithiasis, also known as benign paroxysmal positional vertigo, refers to brief paroxysmal attacks of vertigo and nystagmus that occur when the head moves rapidly to a specific position. The pathogenesis is mainly that the otoliths from the ampullar ridge of the semicircular canal of the inner ear fall off and enter the semicircular canal, stimulating the lymph fluid and causing vestibular nerve impulses, leading to vertigo symptoms.

[0003] Now there is a very good treatment for otolithiasis. It does not require medication and has miraculous effects, which can be said to be immediate. This treatment method is called "manual repositioning therapy". Specifically, the doctor changes the position of the patient's head to allow the detached otoliths to return to their original place so that they can no longer stimulate the nerve endings, and naturally there will be no dizziness. The doctor can suspend the treatment at any time if there is any discomfort during the manual repositioning process, and adjust the intensity and rhythm of the treatment at any time before the patient has nausea symptoms.

First, the first adjustment component 2 is used to control the angle between the head board 14 and the back board 13, so that the human head rotates 45° to the left. Then, the second adjustment component 3 is used to lower the back board 13 to be on the same plane as the lower body board 12. Then, the first adjustment component 2 is used to make the human head lean back 30° and hold for 30 seconds. Then, the first adjustment component 2 is used to rotate the head 90° to the right and hold for 30 seconds. While keeping the head unchanged relative to the torso, the first adjustment component 2 is rotated 90° to the right through the third adjustment component 5. The third adjustment component 5 drives the mounting cover to rotate 90° in the mounting seat. The patient changes from a prone position to a lateral position. The side support board 17 supports the patient and holds for 30 seconds. The mounting hood body is rotated 90° in the opposite direction to release the fixing effect of the helmet 15 and the straps 16 on the patient, and the patient is lifted up. The present invention sets a first adjustment component 2 to control the angle of the head plate 14 and the back plate 13. Since the patient's head is fixed to the helmet 15, and the helmet 15 rotates synchronously with the head plate 14, the first adjustment component 2 can accurately control the angle of the patient's head rotation, and the second adjustment component 3 is used to control the erection and lowering of the back plate 13 to control the patient to lie flat or sit up. The third adjustment component 5 controls the rotation of the mounting hood cylinder 41, so that the patient can switch between the prone position and the lateral position, avoiding the situation in the prior art that the doctor controls the patient's head to rotate, and the head changes the angle involuntarily due to the patient's dizziness, and the doctor needs to readjust the angle. In addition, when changing the patient from the prone position to the lateral position, no manual assistance from medical staff is required, which reduces the workload of medical staff. ;

[0021] As an improved specific implementation manner, the third adjustment component 5 includes a driving rod 51, a rotating motor 52 and a plurality of resistance blocks 53.

The upper annular wall 541 is provided with a first notch near the guide plate 55 to form an inlet 543 that penetrates the annular groove 540. The lower annular wall 542 is provided with a second notch near the guide plate 55 to form an outlet 544 that penetrates the annular groove 540. When the rotating motor 52 is started, the driving rod 51 and the driving disk 54 rotate. When the guide plate 55 rotates until it contacts the resistance block 53 located in the annular groove 540, the resistance block 53 is driven to disengage from the annular groove 540 from the outlet 542. At the same time, the mounting cover tube 41 rotates, and the next resistance block 53 enters the annular groove 540 from the inlet 541.

[0022] In this embodiment, a switch button for turning on the rotating motor 52 may be provided on the fixed seat 42. Through the above technical solution, when it is necessary to rotate the mounting cover tube 41, the rotating motor 52 is turned on to rotate the driving rod 51 connected to the output end of the rotating motor 52, and the driving disk 54 fixedly mounted on the driving rod 51 also rotates synchronously. When the guide plate 55 rotates to contact the interference block 53 located in the annular groove 540, the driving disk 54 continues to rotate, driving the interference block 53 to separate from the annular groove 540 from the opening. While the interference block 53 moves, the mounting cover tube 41 also rotates, driving the next interference block 53 to enter the annular groove 540 from the entrance 541.

The worm 22 is meshed with the turbine 21, one end of which is rotatably set on the inner wall of the sliding groove 130, and the other end extends to the second guide groove 131. A manual knob 24 is provided on the end of the worm 22 extending out of the second guide groove 131. When the manual knob 24 is rotated, the worm 22 rotates, driving the turbine 21 to rotate, and the head plate 14 rotates closer to or away from the lower body plate 12.

[0024] Through the above technical solution, when it is necessary to control the patient's head to tilt back or lower its head, the doctor can turn the manual knob 24 to rotate the worm 22, and the turbine 21 meshing with the worm 22 rotates, driving the head plate 14 to move closer to or away from the lower body plate 12. Since the worm gear 22 is self-locking, the turbine 21 can only be driven by the worm 22 to rotate, thereby avoiding the need to readjust the position of the head due to the patient's head rotating after the patient's head is positioned. A scale can be set on the side of the back plate 13 close to the worm 22, and the scale is set around the turbine 21. An indicator block is set on the turbine 21 to indicate the rotation angle of the head plate 14.
