Description
~.~'7~
The present invention relates to a dental training con-sole for enabling dental students or apprentices to practice or learn dental treatments or techniques.
Hitherto, a single training chair has been prepared spe-cially for a dental student. The chair is provided at one side thereof with a model of a human head, and on both sides with sy-ringes, a vacuum pump, handpieces, and other necessary instru-ments.
With such an arrangement, a number of dental training stations must be positioned in rows spread over a large area.
This has the disadvantage that, when a large number of dental students are instructed at the same time, the instructor is un-able to supervise-all the students. Fw~hermore, some students far from the instructormay not be able to hear the instructor properly, and therefore may not be able to follow his instructions.
In order to eliminate the foregoing disadvantages, it has been proposed to position the training stations opposite one another in a straight line. However, in this case the instructor cannot sit on a chair in a fixed position, since he would be un-able to check each student's way of holding an instrument, the motion of his hands, and his operating posture. The result is that the instructor fails to communicate his own wishes to the students.
According to the present invention there isprovided a dental training console for dental students, comprising a plura-lity of models of human heads placed at suitably spaced intervals in opposing pairs lengthwise of the console, platforms for dental instructors mounted at both ends of said console, and chairs for said dental instructors on said platforms.
With this arrangement, two instructors sitting on the chairs positioned higher than their students are able to commu-nicate effectively with the latter. Moreover, according to this ~, ~7~,3~rt~
system, the instructors can well observe how .the apprentices are operating their h.ands, how they hold dental instruments, and how they are using the same. Thus, the dental students are also able to learn exactly how to carry out dental treatment in a relative-ly short length of time.
In one embodiment of the invention there is provided a dental training console wherein an opening is formed at the side of the cabinet on a supporting base having a model of a man's head, thereby partially forming a space for placing dentistry articles such as a kneading plate member. The space can be used effectively by dental students when, for example, they knead fil-ling material for rigidly fixing a crown, and when mixing medi-cines for protecting dental pulp. Furthermore, the arrangement may be such that the students arms and hands are prevented from : moving to an extreme, whereby their operating point is limited excessively so as to encourage the students to carry out an exact dental treatment in a stable seated posture.
The dental training console may be constructed so as to have an upper portion which is pitched, for example of generally conical cross-section, so that no object can be placed thereon, encouraging the dental students to develop the habit of always placing instruments in fixed positions. Along the highest line or ridge of the conical section upper portion there may be substan-tially T-shape light-supporting menbers so that the two opposed model heads of each of.a number o~ longitudinally distributed pairs of models are uniformly illuminted ~y a single lightO
With this arrangement, the instructors are able to observe the operating manner of their dental students with their field of vi-sion being intercepted.
The dental tra~ning console may have a special rotary or swiyel chair for each.student, which can rotate within a fixed range, with its rotational centre located in a substantially ver-~` .
tical orientation with respect to an oral cavity of each model head, whereby the dental students are naturally able to develop the habit of moving relative to the oral cavity of each patient.
Each rotary or swivel chair may have a seating posture guide member such ac a pole provided laterally in the middle por-tion of a back seat plate of the chair, so adapted that when a den-tal student seated on the chair straightens the line of his or her backbone, the guide pole comes into contact with the backbone of the student to its uppermost portion. Thus if the students do not feel their backbones touching the posture guide poles, they will realize that their seating posture is not right. By learning their seating posture in this way, the students can de-velop the habit of operating in a correct seated posture for a long period of time.
The present invention will now be described in more de-tail, by way of example only, with reference to the accompanying drawings, in which:-Figure l is a perspective view showing, as a whole, a dental training console embodying the invention;
Figure 2 is a partial and enlarged perspective view of the dental training console of Figure l;
Figure 3 is a partial, en]arged, cutaway plane view of the dental training console of Figure l; and Figure 4 is a perspective view of one of the student's chairs forming part of the dental training console of Figures 2 to 4.
In the accompanying drawings, numeral l generally desig-nates the dental training console l, which includes an elongate main body. The console l further includes opposed pairs of den-tal practice chairs 18, the two chairs of each pair being dispos-edon opposite sides of the main body, and being inter-connected in a straight line generally transverse to the longitudinal direc-'~
3~7 tion of the main body, and the pairs of opposed shairs being spaced apart along the length of the mainbody, as apparent from Figure 3. The main body of the dental console 1 is provided in or at both longitudinal ends thereof with platforms 2, 2a for instructors, which platforms are positioned above the level of the main floor. On the platforms 2, 2a there are rigidly fixed ro-tary or swivel chairs 3, 3a for the instructors. On the upper part 5 of the dental training console above said platforms 2, 2a, there are mounted semi-circular tables 4, 4a.
The longitudinal central portion of the upper part 5 of said dental training console 1 is raised to form a ridge 5a from which said part 5 is inclined downwardly towards its opposite sides or ends as viewed in cross-section, thereby to form an eqi-lateral triangle. Along both sides of said upper part 5 are placed, at equally spaced apart intervals, a plura~ity of oppos-ed models 6 of human heads, for example models of adult male heads.
On the ridge 5a of said upper part 5 are provided a num-ber of light-supporting members 8 corresponding to the number of pairs of said model heads 6. The uppermost portion of each light-supporting member 8 is divided into two light-supporting elements 8a extending in opposite directions transversely of the main body, with a light 9 mounted at the outer end of each element 8a.
Inasmuch as said light-supporting members 8 are provid-ed along the highest line or ridge of the upper part 5 of the dental training console 1 as mentioned above, instructors are able to observe their students in the field of their vision.
Moreover, with this arrangement, the two opposed model heads 6 of each pair can be uniforml~ illuminated by means of a single light-supporting member 8.
Each model head 6 is supported in vertically movable andfixabie relation ~ithin a fixed range of movement on the middle ~,j",,.~ .
~ '7~7 Portion of a support 11 by means of a pole, bar or the like,which support 11 has a horizontal upper surface projecting arcua--tely from both sides of an upper vertical wall 10 of said den-ta] training console 1. At the left hand side of said support 11 there is received a vacu-um pump 12 which can be withdrawn from the support, while at the right hand side~are mounted handpieces 13, 14 as shown in Figure 2. The handpieces may, for example, serve to receive drilling, grinding and/or buffing elements, and one of the handpieces may be adapted for high speed operation and the other for lower speed operation.
~ t the right hand side of each model head 6 is pro-vided a container 15 having a door, and an upper shelf 15a which is adapted for placing,-or-intended to receive, a dental t ay 16.
The tray has an edge to which there is fixed a handpiece-retaining means 17 formed with a notch on the upper portion and the under portion thereof. Said handpiece-retaining means 17 is adapted to permit said handpieces 13, 14 to be releasably supported there-by, for example to be insertable therein.
At the side of said container 15 above said support 11, an inwardly extending space S is formed by cutting said vertical wall 10, so as to provide a place for receiving a kneading plate 17 whereon a filling material or medicines for protecting the dental pulp can be kneaded. In each position corresponding to said model heads 6 there is suitably positioned a chair 18 for a student. The rotational center P of each chair 18 is pivotally supported in a position which is-vertically below the associated model head 6. The chair 18 has a seat plate 19, the lower sup-porting pole 21 of which is provided with an adjusting lever 22 which is vertically movable so as to adjust the seat plate 19 to the length of legs of the student seated thereon.
From the middle of the bac~ of the seat portion of the seat plate 19 there is erected a guide member or pole 23 adapted 3~
to guide a seated student so as to keep him in a correct seated posture. Further, the student's chair 18 has a generally T
shape base including a connecting leg member in the form of a bar or pole 24 whi'ch is bored with a plurality of holes 26 at suitably spaced intervals. ~ selected one of the holes'26 receives a ~olt 25 so as to permit a seated student to adjustably fix the spacing of the chair with respect to the pivot point P below the oral cavity of the model head in a position ~hi~h suits his legs.
In this position, the bolt 25, after being inserted into the ap-propriate hole 26, is fixed by screwing it in a screw-threaded hole 28 formed in a boss on a base 27, pivotally mounted on the pivot point defined by the opening, boss or the equivalent 20, as shown in Figure 4.
The base of the chair includes a lateral leg member 29 connected across the connecting leg member 24, and in the opposite ends of the member 29 are molmted casters 30 having mutually in-clined rotational axes. Thus every dental student is able to learn how to move in a limited plane or area with the model's oral cavity as its centre, as if the student were treating a real den-tal patient.
When practicing dental treatment, each dental studentsits on a rotary chair 18 mounted in association with one of the model heads, and adjustably fixes the height of the seat plate 19 and the spacing of the latter from the pivot point, to the most suitable position for his legs. Then two dental instructors sit on the chairs 3, 3a, respectively on the platforms 2, 2a. The instructor seated on the left-hand chair 2 as viewed in Figure 1 observes a group of students at his side from the platform 2, i.e.
from a position higher than the students, while the other instruc-tor seated on the right-hand chair 3a observes another group of students at his side from the platform 2a, likewise from a vantage point higher than the'latter group. Thus both instructors are able to carefully observe how the two groups are operating their hands and using dental instruments.
The instructors may place on the tables 4 all necessary -books and dental instrumen-ts, giving instructions to the groups, or may be able to Sive -then a practical demonstration if neces-sary~
As will be clearly understood from the foregoing des-cription, the dental instructors are positioned higher than the dental students so that they can precisely not only give their verbaI instructions to the dental students in an audible manner but also confirm the smallest motion of the student's hands and the manner in which they use the dental instruments.
When use is made of the dental training console l, to train both dental students and dental assistants, a chair 18 may be moved from the full line to the broken line position shown in Figure 3, in which it is moved to the model head 6 which is posi-tioned adjacent thatnormally served by the moved chair, so as to enable the assistant to use the adjacent model head 6, thus mak-ing it possible for both the students and the assistants to make use of the same model head 6.
