Description
Technical Field
The invention relates to a vertigo diagnosis and treatment device, and belongs to the technical field of vertigo diagnosis and treatment equipment.
Background
The vestibule is a main organ for human body balance, and the important structure in the vestibule, which is sensitive to human body posture change, is the semicircular canal which is divided into a horizontal semicircular canal, an upper semicircular canal and a rear semicircular canal, and the planes of the three are mutually vertical to sense the human body posture change in different planes. When the posture of a human body changes, the stimulation intensity of different semicircular canals is different, and when the stimulation on two sides is unbalanced, the eye shake occurs, and the direction of the eye shake faces to one side of the strong stimulation. Therefore, corresponding semicircular canals can be stimulated through the acceleration or deceleration rotation of different semicircular canal planes, so that the balance condition of the function of the vestibules at both sides and the corresponding function condition of the semicircular canals can be known through the examination of the eye shock when the acceleration or deceleration rotation of different directions and different planes is carried out. In addition, through medical clinical research, it has been found that positional vertigo is directly related to vestibular otolith shedding, positional vertigo can be induced by placing a human body in a certain specific posture, and after the shedding otolith is restored by adopting a specific posture, the positional vertigo symptoms of most patients can be clinically cured, and the used devices are basically used for diagnosis and treatment through posture rotation of the patients in three dimensions, such as a posture rotating device and system disclosed in chinese patent document CN101779948B, and a gear type vertigo diagnosis and treatment system disclosed in chinese patent document CN105193389A, or an examination chair disclosed in chinese patent document CN 1901869B. In many body position rotating apparatuses such as this, a safety chair for fixing a patient is basically mounted on a first frame capable of rotating along a first axis, and the first frame is mounted on a second frame capable of rotating along a second axis perpendicular to the first axis, and the two frames are driven to rotate by two motors, respectively. While performing the diagnosis, the doctor rotates the patient slowly in three dimensions, and if positional vertigo is diagnosed, the doctor rotates the patient rapidly in a given plane and suddenly decelerates, thereby detaching the otolith causing the vertigo from the sensitive area. In order to ensure that a patient does not fall off in the rotation process, a seat in the existing diagnosis and treatment device can fix the patient by using a safety belt, and the mode is not particularly convenient and has an unsatisfactory safety effect. In addition, the patient is changed by multi-dimensional rotation at present, because there is no good device for directly realizing the swinging of the body of the patient, so that a novel vertigo diagnosis and treatment device needs to be designed for the situation.
