Abstract

<P>PROBLEM TO BE SOLVED: To allow an operator to get close to the oral cavity of a patient as possible in order to perform a more accurate dental treatment by narrowing the width of a shoulder section of a backrest of a dental treatment chair. <P>SOLUTION: The dental treatment chair has the backrest 12 and a contour seat 13. The backrest 12 can be erected and flattened with respect to the contour seat 13. The backrest 12 has backrest supports B<SB>R</SB>and B<SB>L</SB>extending to both sides for supporting the upper arms of a patient. When performing a dental treatment on a lying patient by flattening the backrest 12, the arms of the patient are supported by the backrests B<SB>R</SB>and B<SB>L</SB>. Because the width W of the shoulder section of the backrest 12 can be narrowed in such a configuration, the operator can get more close to the oral cavity of the patient. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a dental treatment chair, and more particularly, in a dental treatment chair having a backrest and a contour seat, and the backrest can be tilted with respect to the contour seat. The dental treatment chair and the treatment chair are designed so that the operator can get closer to the patient and perform more reliable treatment during the dental treatment. The present invention relates to a dental treatment chair that prevents an elbow rest from getting in the way when getting on and off.

  FIG. 3 is a schematic perspective view of an essential part for explaining an example of a conventional dental treatment chair, and the dental treatment chair 10 includes, as is well known, an anvil base 11, a backrest 12, a contour seat 13, The legrest 14, the footrest 15, the elbow rest 16 integrated with the backrest 12, etc., and the backrest 12 can be raised and lowered with respect to the contour seat 13 in the direction of arrow A and provided in the base 20. The mechanism can move up and down and tilt.

In the dental treatment, the patient sits on the treatment chair 10 and receives the treatment with the head fixed to the cradle 11. During the treatment, the surgeon moves the treatment chair 10 up and down, tilts, tilts, etc. to make the patient easy to treat, and the surgeon can do so if he can approach the patient's oral cavity. The easier it is to treat. However, in the conventional dental treatment chair, both sides of the backrest 12 are formed wide to obtain a space for placing the patient's arm during dental treatment (when the backrest is collapsed). There was an inconvenience that the surgeon could not get close to the patient's mouth.
Further, in the conventional dental treatment chair, when getting on and off the treatment chair, the elbow support becomes an obstacle, and it is particularly difficult to get on and off from the side.

  The present invention has been made in view of the above circumstances, and in particular, the shoulder width of the backrest of the dental treatment chair is narrowed so that the operator can be as close as possible to the oral cavity of the patient. The purpose is to enable accurate dental treatment.

  In addition, the elbow rest can be tilted outward, and the elbow rest can be used as a seat by making the elbow rest horizontal. Thus, it was made for the purpose of facilitating getting on and off the dental treatment chair.

  The invention according to claim 1 includes a dental treatment chair having a backrest and a contour seat, and the backrest extends up and down on both sides to support the patient's two arms. It has a backrest support.

  The invention of claim 2 includes a dental treatment chair having a backrest and a contour seat, and the backrest can be tilted with respect to the contour seat, wherein the contour seat has a side support for receiving the patient's elbow on both sides. And the side support can be tilted to the side, and can be locked on substantially the same surface as the contour sheet when the side support is tilted.

  A third aspect of the present invention is a dental treatment chair having a backrest and a contour seat, wherein the backrest can be tilted with respect to the contour seat, and the contour seat has a side support for receiving the patient's elbow on both sides. The side support is capable of being raised and lowered to the side, and is perpendicular to the side surface of the contour sheet when being lowered.

  According to a fourth aspect of the present invention, in the dental treatment chair according to the second or third aspect, the backrest has a backrest support that extends to both sides and supports the patient's two arms.

  Since the shoulder width of the backrest of the dental treatment chair is narrowed so that the surgeon is as close as possible to the patient's oral cavity, more accurate dental treatment can be performed.

  Furthermore, since the elbow rest can be raised and lowered, and the elbow rest can be used horizontally as a seat portion, it is easy to get on and off the dental treatment chair, or the elbow rest can be tilted and the elbow rested. It was made easier for people to get on and off the dental treatment chair because the reception was not disturbed.

FIG. 1 is a schematic configuration diagram of a main part for explaining an embodiment of a dental treatment chair according to the present invention. Parts that perform the same function throughout the drawings are denoted by the same reference numerals, and each time the explanation is given. Is omitted. In FIG. 1, B _R and B _L are backrest supports provided in the lateral direction below both sides of the backrest 12 (below the shoulders). upper arms of is adapted to ride on the said backrest support B _R, B _L. This gives the patient a sense of support, allows the patient to relax and receive treatment, and does not get tired even when receiving treatment for a long time. Moreover, by doing in this way, the width W of the shoulder part of the backrest 12 can be narrowed with respect to the conventional dental treatment chair shown in FIG. The treatment can be performed close to the point, and more accurate treatment can be performed. In addition, since the patient can receive treatment without taking an unreasonable posture, the burden on the operator can be reduced.

In FIG. 1, S _R and S _L are side supports provided on both sides of the contour sheet 13, and these side supports S _R and S _L are in a standing state during dental treatment as shown by a solid line in FIG. It is locked so that the patient can use it instead of a gripping place or an elbow rest. As shown by broken lines S _R1 and S _L1 in FIG. 1, the side supports S _R and S _L can be locked by being tilted so as to be horizontal. In this case, it is particularly easy to get on and off from the lateral direction. For example, the user can sit down on the side support locked in the horizontal state and then move onto the contour seat 13. When sitting down, it becomes a wide seating surface, so it is easy to sit down on a chair, and further, it is possible to get off after shifting to the side, so for example, the footrest 15 does not get in the way and more easily You can get off.

2, the side support _S R, a diagram for explaining a further usage of the _{S L,} these side support _S R, _{S L,} in FIG. 2, as shown by the dotted line _{S R2, S L2,} contour The seat 13 can be tilted substantially parallel to both sides, and by doing so, it is also possible to facilitate boarding and exiting from the lateral direction.
