Description

[Detailed Description of the Invention] The present invention relates to a chair for trainees used when they practice dental treatment.

Currently, in dental educational institutions, a plurality of training tables are set up side by side on the floor, a human head model is attached to these, and treatment training is carried out using treatment instruments according to the instructions of the professor.

However, there is no special chair for the trainee used in the dental training equipment, and a commonly used rotary chair with casters that is freely movable is used.

In actual dental treatment by a dentist, the dentist's position relative to the patient's oral cavity and the treatment posture are important factors.
If you do not perform medical treatment while maintaining the correct position and posture, treatment errors are likely to occur, the efficiency will be low, and you will feel fatigued even after short treatment sessions.

The present applicant has conducted various studies as a means to correctly regulate the medical treatment position of dentists and dental trainees, and the present invention is particularly designed to maintain the posture of dental trainees with their backs straightened, The purpose is to help students acquire the correct clinical posture during the practical training course.

An embodiment of the present invention will be explained below with reference to the drawings.
Reference numeral 1 designates a dental training device in which two facing training tables are arranged in a straight line, and at both ends of the apparatus in the longitudinal direction there are tables 2, 2 for the teacher, which are higher than the floor bones. The supports of rotating chairs 3, 3 for the professor to sit on are fixed on the stands 2, 2.

Above each of the tables 2, 2 is a mounting table 4 whose peripheral edge is shaped like an arc, in order to place the teacher's notes, teaching tools, etc.
, 4 are installed.

The upper part 5 of the training device 1 is formed in the shape of a roof that is highest at the center and slopes downward toward both sides in the width direction,
At opposite positions on both sides are human head models 6, 6...
are arranged at equal intervals.

At the top of the roof 5, a light support 8 is provided for illuminating the oral cavity parts 7, 7, . . . of the human head models 6, 6, . . .
, 8 . . . are provided, and lights 9 , 9 .

The human head models 6, 6... are placed over a certain area in the center of support stands 11, 11... whose upper surfaces are horizontal and project in an arc shape on both sides from the vertical wall 10 above the training table. The vacuum 12 is supported so that it can be moved vertically and fixedly within the support base, and the vacuum 12 can be freely pulled out and stored on one side of the support base, and the high-speed vacuum cleaner 12 can be freely stored on the other side.
A low speed band piece 13, 14 is provided respectively.

On one side of each of the human head models 6, 6, a storage section 15, 15 for storing instruments, etc. is provided, and a dental tray 16, 16, . A locking tool 17 having recessed fittings on the upper and lower sides is fixed to the side edge of this dental tray.
The high and low speed band pieces 13 and 14 are inserted into the band pieces.

A space S facing inward is formed by cutting a part of the vertical wall 10 on the storage section 15 side of the upper part of the support stand 11,
It constitutes a placement section for the kneading plate 17.

Rotating chairs 18, 18, . . . for trainees are arranged corresponding to each of the human head models 6.

The center of rotation F of this rotary chair 18 is the center of rotation of the human head model 6.
The lower column 21 is pivotally supported by a pin 19 at a substantially vertically downward position, and an adjustment lever 22 is provided on the lower column 21 so that the seat plate 20 can be raised or lowered according to the length of the trainee's legs.

A guide pole 23 is erected at the center of the back of the seat plate 20 of the rotary chairs 1B, 18, . . . for guiding the trainee's back muscles straight and regulating the medical treatment posture.

In this chair 18 for trainees, insertion holes 26 for bolts 25 are provided at regular intervals in the connecting rod 24 so that the seat plate 20 can be moved and fixed in the far and near direction from the pivot point P in front of the lower part of the oral cavity. It can be screwed into a screw hole 2B of a board 27 pivotally attached to a pivot point P.

A supporting leg 29 is connected perpendicularly to the connecting rod 24, and casters 30 inclined in the direction of rotation are attached to both ends.

A stopper 31 is provided on the floor to abut the connecting rod 24 so that the chair 1B can rotate only within a certain range.

As explained above, according to the dental training device of the present invention, the center of rotation of the rotary chair for trainees is located approximately vertically below the oral cavity of the human head model, and We installed a guide pole upward in the center, so if the trainee sits on this chair and stretches his/her back straight, his or her vertebrae will touch the guide pole up to the top and sense their posture. It can be used as a guide for recognizing poor posture and correcting it correctly.

By repeating training using this type of dental training equipment, trainees will naturally acquire the correct posture with their backs straight, and will be able to maintain this posture during actual dental treatment, thereby reducing medical errors. As this decreases, you will feel less tired even during long medical treatment sessions.
