Description

  The present invention relates to a dental treatment chair, and more particularly to a dental treatment chair that holds a patient's cervical vertebrae and can reduce fatigue of the cervical vertebrae.

  FIG. 2 is a schematic configuration diagram of an essential part for explaining an example of a dental treatment chair to which the present invention is applied. In the figure, 10 is a dental treatment chair, 11 is a headrest, and 12 is a back. Rest, 13 is a contour seat, 14 is a leg rest, 15 is a footrest (foot step), 16 is a base, and the dental treatment chair 10 is normally in an up state, as is well known, The patient gets on the foot step 15 and then sits on the contour seat 13. Thereafter, the surgeon (doctor) wakes up the chair 10 by performing the treatment with the chair in a fallen state (sleeping state), or raising the chair so that the patient can easily gargle by raising the chair. Alternatively, the dental treatment is performed in the fall state.

  In the dental treatment chair as described above, for example, when a patient is treated for a long time, fatigue such as stiff shoulders may be complained.

  The present invention solves this problem and provides a cervical vertebra holding means for holding the patient's cervical vertebra, and the cervical vertebra holding means holds the patient's cervical vertebra during dental treatment, thereby reducing fatigue such as stiff shoulders of the patient. It is intended to reduce.

  The invention of claim 1 has a holding means for holding the patient's cervical vertebra between the headrest and the contour sheet, and the headrest has a supporting means for supporting the holding means.

  According to a second aspect of the present invention, in the first aspect of the invention, the holding means includes a heater.

  According to a third aspect of the present invention, in the first aspect of the invention, the holding means is made of a gel-like material, and the holding means includes a heater for heating the gel-like material.

  According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects, the supporting means includes a spring member, and the holding means is pressed against the cervical vertebra of the patient by the spring force of the spring member. It is characterized by that.

  According to the present invention, since the holding means for holding the patient's neck is provided and the patient's neck is supported by the holding means during the dental treatment, the neck may be tired even during long-term dental treatment. There is nothing, and fatigue such as stiff shoulders can be reduced.

Furthermore, since the holding means is made of a gel-like material to support the neck evenly, it is possible to prevent a local burden on the patient's neck,
Furthermore, because the holding means is provided with a heater so that the holding means can be heated, the cause of stiff shoulders can be reduced by relaxing the tension of the patient's neck,
Furthermore, since a spring member is provided in the holding means so that the patient's neck can be reliably supported by the holding means, a sense of security can be given to the patient.

  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, and FIG. 1A is a headrest portion of the dental treatment chair according to the present invention as viewed obliquely from the front. FIG. 1B is a side view of the headrest portion, in which the same reference numerals are given to the portions that operate in the same manner as the conventional dental treatment chair shown in FIG. It is.

  In FIG. 1, reference numeral 20 denotes a holding means added according to the present invention. The holding means 20 is attached to the lower part of the headrest 11 (between the headrest 11 and the backrest 12), and the patient sits on the dental treatment chair 10. Configured to hold the patient's back of the neck. Specifically, when the patient sits on the dental treatment chair 10, for example, it is formed in an arc shape so as to cover the rear side of the patient's neck, or as shown, it is formed of a gel-like material, When it is pushed by the neck, it is deformed to fit the shape of the neck. Reference numeral 21 denotes a support means for supporting the hold means 20, and the support means 21 is integrally attached to the headrest 11. For example, the position of the hold means 20 is supported by a link mechanism or the like so as to be adjustable. . An elastic member (not shown) such as a spring is provided between the support shaft 21a of the support means 21 and the fixed arm 11c of the headrest 11 that rotatably supports the support shaft 21a. This elastic member pushes the holding means 20 weakly forward (in the direction of arrow A), and when the patient sits on the chair 10, the holding means 20 is pushed back on the back side of the patient's neck against the elastic force of the elastic member. Thus, the holding means 20 is adapted to fit the patient's neck.

  11a and 11b are well-known mechanisms in the dental treatment chair, 11a is a link mechanism unit including a motor and a link mechanism that can move and tilt the headrest 11 in the front-rear direction, and 11b is the link mechanism unit. It is a headrest attachment support | pillar which supports the headrest part 11 containing 11a so that a vertical movement is possible. The link mechanism 11 a and the column 11 b can be adjusted so that the neck of the patient fits the headrest 11 by adjusting the position and inclination of the headrest 11 in the vertical and longitudinal directions.

  Preferably, as described above, the holding means 20 is formed so as to be deformable with a gel-like substance, and when the patient's neck is pressed, the holder 20 is deformed so as to fit the shape of the neck. In addition, the force is applied almost evenly to the neck, so that the patient does not feel uncomfortable.

  Further, the holding means 20 is provided with a heater (not shown) for warming the gel-like substance, and if necessary, the gel-like substance is warmed to warm the patient's neck and perform a warming massage or the like. If done, the patient's fatigue can be reduced more effectively.

It is a principal part schematic block diagram for demonstrating one Example of the chair for dental treatment by this invention. It is a principal part schematic block diagram for demonstrating an example of the conventional dental treatment chair with which this invention is applied.
