Description

Novel inspection chair

Technical Field

The invention relates to a novel inspection chair, and belongs to the technical field of vertigo diagnosis and treatment equipment.

Background

The vestibule is a main organ for balancing human body, the important structure for sensing the posture transformation of the human body in the vestibule is a semicircular canal, the semicircular canal is divided into a horizontal semicircular canal, an upper semicircular canal and a rear semicircular canal, and the planes of the three are mutually perpendicular to each other to sense the changing postures of the human body in different planes. When the posture of the human body changes, the stimulation intensity of different semicircular canals is different, and when the bilateral stimulation is unbalanced, the eye shake occurs, and the direction of the eye shake faces to the side of the strong stimulation. Therefore, the corresponding semicircular canals can be stimulated by accelerating or decelerating rotation of different semicircular canal planes, so that the balance condition of bilateral vestibular functions and the corresponding semicircular canal function condition can be known by checking eye shake when accelerating or decelerating rotation of different directions and different planes is carried out. In addition, through clinical medical research, it has been found that the position dizziness is directly related to the vestibular otolith shedding, the position dizziness can be induced by placing a human body at a specific position, most of the patient's position dizziness symptoms can be clinically cured after the shedding otolith is reset by adopting the specific position posture, and the used equipment is basically used for diagnosing and treating the position dizziness symptoms through the position rotation of the patient in three dimensions, such as a position rotating device and system disclosed in Chinese patent document CN101779948B, a gear type vertigo diagnosing and treating system disclosed in Chinese patent document CN105193389a, or an inspection chair disclosed in Chinese patent document CN 1901869B. In many posture rotating apparatuses such as these, basically, a safety chair for fixing a patient is mounted on a first frame rotatable along a first axis, and the first frame is mounted on a second frame rotatable along a second axis perpendicular to the first axis, and the two frames are rotated by two motors, respectively. The doctor rotates the patient slowly in three dimensions while making the diagnosis, and if positional vertigo is diagnosed, the doctor rotates the patient rapidly in a given plane and decelerates suddenly, thereby disengaging the otoliths causing the vertigo from the sensitive area. At present, the body position of a patient is changed by a multi-dimensional rotation mode, because no good equipment can directly realize the swing of the body of the patient, and therefore, a novel examination chair needs to be designed for the situation.

The transmission mechanism comprises a crank-link mechanism.

The transmission mechanism comprises a gearbox connected to the power output end of the driving motor, a swing rod connected to the gearbox and a connecting rod hinged to the swing rod, and the connecting rod is hinged to the lower arm.

By adopting the technical scheme, the novel inspection chair is driven by the two driving motors, so that the two lower arms connected with the driving motors through the transmission mechanism swing to different angles, and the four swing arms are driven to change different forms so as to swing the chair to different angles. The novel examination chair not only is provided with the main bow and the auxiliary bow for driving the chair to rotate, but also is provided with the swinging device for driving the chair to swing, so that examination or treatment of patients is more convenient.
