Description

  The present invention relates to an abutment base in a dental treatment chair, and more specifically, when a dental treatment chair is placed in a fall (sleeping) state to treat a patient's upper teeth and the like, the lower part of the main part of the ankle base is a cervical spine of the patient In other words, the lower part of the main part of the head is notched upward, and the concave part (the lower part of the main part of the head) is fitted to the patient's cervical spine. It is possible to prevent the patient from feeling uncomfortable, and to make the dental treatment comfortable for the patient with the ponytail so that the hair hangs down through the space notched into the concave shape for the patient with the hairstyle ponytail. The present invention relates to a pedestal for a dental chair that can be received.

  FIG. 3 is a schematic configuration diagram of a main part for explaining an example of a conventional dental treatment chair. In FIG. 3, 10 shows the overall configuration of the dental treatment chair. It consists of a head base (main body) 11, a backrest 12, a contour seat 13, a leg rest 14, a footrest 15, and the like. During the dental treatment, the patient sits on the contour seat 13 and is in an upright state (state shown by a solid line in FIG. 3). Or receive medical care in a fallen (sleeping) state (indicated by a broken line in FIG. 3).

  FIG. 4 is a diagram showing the relationship between the patient's head and the cradle (main body part) 11 when receiving medical care in the fall (sleeping) state. The lower part 11a is raised upward so that the upper teeth of the patient can be seen well by the operator, in other words, the medical treatment is performed with the patient's crown on the lower side.

  Thus, in the conventional Antodai, as shown in FIG. 3, the lower part 11a of the Antodai (main body part) 11 protrudes substantially horizontally or slightly downward. Therefore, as shown in FIG. As described above, when performing medical care in the fall (sleeping) state, especially when treating the patient's upper teeth, etc., the top of the patient's head should be positioned downward so that the operator can see the patient's mouth well. When the head base (main body part) 11 is tilted so that the lower part 11a of the head base (main body part) is directed upward, the lower part 11a of the head head base (main body part) 11 is placed on the patient's cervical spine. There was a problem such as pressure on the cervical spine and discomfort to the patient.

  The present invention has been made to solve the above-described problems. In particular, when a patient is placed in a fallen (sleeping) state to treat maxillary teeth and the like, the lower part of the head (main body) is placed on the patient. The purpose of the present invention is to allow dental treatment without causing discomfort to the patient so as not to compress the cervical spine.

In order to achieve the above object, the present invention provides
A first invention is an ancillary table to be mounted on a tiltable dental treatment chair, and the ancillary table has a concave shape in which a lower part of a main body supporting a patient's occipital region is cut out upward. It is characterized by being.

  According to a second aspect of the present invention, in the first aspect of the present invention, the size of the concave shape notched in the ankle base body portion is such that the lower portion of the ankle base body portion defines the patient's cervical vertebra during a fall (sleeping) medical treatment. It is characterized by its size not to be pressed.

  A third invention is characterized in that, in the first or second invention, the anvil main body can be tilted back and forth.

  According to a fourth invention, in any one of the first to third inventions, a cushioning material is housed in a lower portion of the head base main body.

  According to a fifth invention, in the fourth invention, the cushion material is a gel-like substance.

  When treating the patient's maxillary teeth etc. with the dental treatment chair in the fall (sleeping) state, the lower part of the main body of the head does not press the patient's cervical spine. The lower part of the head is made into a concave shape with the upper part cut out, and the concave part (the lower part of the head base) fits the patient's cervical spine. Furthermore, since the hair can be hung down through the space notched in the concave shape for a patient with a ponytail hairstyle, the patient with a ponytail can receive dental treatment comfortably.

  FIG. 1 is an overall schematic configuration diagram for explaining an example of a dental treatment chair provided with an annulus according to the present invention. The mechanism, function, etc. of the treatment chair body are the same as those of the conventional dental treatment chair shown in FIG. Therefore, parts having the same mechanism and function are denoted by the same reference numerals as those in FIG. 3, and the description thereof is omitted.

  Thus, in the present invention, the lower part 11a of the anvil base (main body part) 11 is formed into a concave shape part 11 ′ cut out upward, so that the patient's cervical spine fits into the concave shape part 11 ′. As a result, when the treatment chair is turned down (sleeping) and the patient's upper teeth are examined, the lower part 11a of the head table (main body part) 11 does not press the patient's cervical spine. ing.

  FIG. 2 is a configuration diagram of a main part when a dental treatment is performed using a dental treatment chair equipped with an anvil according to the present invention, and FIG. 2 (A) is treating a patient's upper teeth. FIG. 2A is a diagram illustrating a state when a patient whose hairstyle is a ponytail is being examined.

When treating the patient's maxillary teeth, etc., as shown in FIG. 2 (A), in order to make it easy for the operator to see the maxillary teeth etc. in the oral cavity, the bald base body 11 is mounted on the bald base support base. 11 ₀ is tilted with respect to lift the bottom 11a of該安Atamadai body 11 upwards, but so that the top portion of the patient is lower, where, in the conventional Ahn head rest body portion, The lower part 11a of the head table main body 11 hits the patient's cervical vertebra and compresses the patient's cervical vertebra to cause discomfort to the patient. In the present invention, as shown in FIG. Therefore, the patient's cervical vertebra fits (enters) into the cut-out recess and does not press on the patient's cervical vertebra.

  If the patient has a ponytail (long hair), as shown in Fig. 2 (B), the ponytail is placed under the head base when the patient is in a lying (sleeping) state (regardless of the treatment of the upper teeth). Since it can hang down through the space of the cut-out recess provided, the patient can receive dental treatment without worrying about hair disturbance.

  As mentioned above, although the embodiment of the Antodai in the dental treatment chair according to the present invention has been described, in addition, when the Antodai main body is tiltably attached to the Antodai support base The tilting of the main unit is large and more effective. In addition, the size of the notch recess in the lower part of the main body of the Antodai is such a size that the patient's cervical spine can enter (fit), and if it is too small, the intended purpose cannot be achieved.

  Furthermore, when a flexible cushion member is stored in the lower part of the main body of the head, even if the lower part of the main body of the head is in contact with the patient's cervical spine, it does not give the patient so much discomfort. Dental treatment can be performed. In particular, when a gel-like substance is stored as a cushioning material in the Antodai main body, if it is stored only in the lower part of the Antodai main body, the amount of gel-like substance used is reduced. Can be cheaper.
