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 was no special chair for the trainees used in the dental training equipment, and a general rotating chair with casters that could be moved freely was used.

However, in actual dental treatment by a dentist, if the center line of the patient's body lying on the examination table is taken as the 12 o'clock line and the 6 o'clock line, and the patient's oral cavity is taken as the center point, then everything will be done at 9 o'clock and 12:30 o'clock. It has been proven that performing the procedure within this range is easiest for dentists to treat, and allows for comfortable posture.

Therefore, attempts have been made to make the dentist's chair rotatable only within the above-mentioned range, using the position vertically below the patient's oral cavity as a pivot point.

Therefore, the present invention allows dentists to use a chair that can only rotate within the above-mentioned range during training during the training stage, so that even if the chair does not have any rotation control means, the dentist will naturally be able to rotate within the above-mentioned range. The aim is to enable medical treatment within the scope.

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

Mounting tables 4, 4 each having an arcuate peripheral edge are attached to the upper part of each of the tables 2, 2 in order to place the teacher's notes, teaching tools, etc.

The roof portion 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, and human head models 6, 6 are placed at opposing positions on both sides.・・・
・ 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 .

In addition, the human head models 6, 6, etc. are fixed at the center of support stands 11, 11, whose upper surfaces are horizontal, and which project in an arc shape on both sides from the vertical wall 10 above the training table. It is supported so that it can be moved vertically and fixedly within a range, and a vacuum 12 is provided on one side of the support base so that it can be freely drawn out and stored, and high-speed and low-speed band pieces 13 and 14 are provided on the other side, 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 portion of the vertical wall 10 on the storage section 15 side of the upper part of the support stand 11,
It constitutes a mounting section for the crosstalk board S.

Rotating chairs 18, 18, . . . on each side of the training are arranged corresponding to each of the human head models 6.

The rotation center P of this rotary chair 18 is determined by the human head model 6.
An adjustment lever 22 is provided on the lower column 21 so that the seat plate 19 can be raised or lowered according to the length of the trainee's legs.
A guide ball 23 is erected in the center of the back of the trainee to guide the trainee's back straight and regulate his or her posture.

In particular, 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 19 can be moved and fixed in the distance direction from the pivot point P below the oral cavity. Screw hole 2B of the board 27 pivotally attached to the pivot point P
It is designed so that it can be screwed together.

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.

And this chair 18 is open from 9:00 to 12:30 as mentioned above.
A stopper 31 is provided on the floor to abut the connecting rod 24 so that the caster 30 can be rotated only within a range of 100 mm, and rotation in the other direction is restricted by the abutment between the caster 30 and the storage section 15.

In this way, according to the dental training device of the present invention, not only can the upper and lower settings be adjusted according to the length of the trainee's legs, but also the distance from the oral cavity can be freely set. It is possible to maintain the optimal clinical posture.

Furthermore, since this chair for trainees only rotates within a certain range as in normal medical treatment, the correct treatment position can be naturally mastered during training.
