Description
[technical field]
The utility model relates to the landing seats more particularly to a kind of seat rotational locking device of patient or disabled person.
[background technique]
Dental patient seat is to play the role of integrated support to the entire body of patient in dental procedure, existing
Dental patient seat generally use three-bend dental patient seat, it is main include control seat cushion elevating movement lifting device,
Control the backrest of pitching movement and the shank elevating mechanism of control leg support lifting.In use, when patient chair drops to most
Low chair position, patient's chair back are raised to highest, and patient chair leg support is preferably minimized, and patient chair footrest is retracted to most in short-term, patient
Chair entirety kenel is that working state facilitates doctor to exchange with patient in this case, completes interrogation process.When patient chair is raised to
Chair position is treated, patient's chair back reduces to minimum, and patient chair leg support is raised to highest, when patient chair footrest reaches longest, disease
People's chair entirety kenel is therapeutic state, in this case, facilitates diagnosis and treatment of the doctor to patient, completes diagnosis and treatment process.
But existing three-bend dental patient seat, it is each in lifting device, backrest and shank elevating mechanism
Partial movement can only realize pitching and the elevating control of seat, can not rotate mostly, and the three-bend dental patient seat having is i.e.
Make to rotate, but have the defects that in terms of rotation angle and locking it is certain, fundamentally limit doctor and patient it
Between the limitation that operates.Such as in dental patient therapeutic process, patient compliance is generally required by head and shows different gestures, sometimes
It also needs patient or medical staff by body inclination, so that medical staff treats or checks, can just see oral cavity in this way
Or medical instrument can properly enter the inside in oral cavity and go, to find out the cause of disease or to be treated；At this moment medical care people is just needed
Member carries out the rotation offset of different angle to seat and quick locking positions, and after seat effective position, could be convenient for medical staff
Dental patient is checked or treated from suitable angles and positions；But existing dental patient functions of seat is insufficient or control
Inconvenience is not easy to medical staff's control, causes to check or therapeutic process is difficult, influence using comfort.
[utility model content]
The utility model provides not to be needed patient and excessively moves in a kind of inspection or therapeutic process, easy to operate, convenient for doctor
