Description

  The present invention comprises a dental treatment unit, more specifically, a dental treatment chair on which a patient sits and receives treatment, and a spit-on device fixedly disposed on the side of the dental treatment chair. In the dental treatment unit in which the spit bowl is adjusted to a position where it is easy for the patient to gargle, and the spit arm is moved and adjusted to a position where the patient is easy to gargle, then the gargle cup is lifted. Occasionally, the rotational position of the spit-on bowl adjusted in rotation is stored in a memory, and thereafter the spit-on bowl is stored in the rotational position stored in the memory until the patient gets out of the dental treatment chair. It is designed to automatically rotate.

  FIG. 1 is a schematic configuration diagram for explaining an example of a dental treatment unit including a spit device to which the present invention is applied (or to which the present invention is applied). The dental treatment unit is a dental treatment chair 1. , Spitton device 2, Spitton arm 3, work table 4, instrument holder 5 and the like, and various instruments 6 used in dental treatment are stored in the instrument holder 5, as is well known. In addition, in the dental treatment, the patient sits on the treatment chair 1 and receives the treatment with his head fixed to the cradle. During the treatment, the surgeon moves the treatment chair 1 up and down, tilts up, tilts, etc. to treat the patient in a posture that allows easy treatment.

The spit arm 3 includes a gargle water supply pipe 7 for jetting gargle water, a cup holder 3 ₁ for placing a gargle cup 8 when gargle water is supplied, and a gargle bowl for discharging gargle water after the patient gargles. consists gargle Hachino portion 3 _2, etc. to put 9, usually, as shown, rotatably attached to the top of the spittoon device 2, upon gargling, is rotated in the arrow a direction, in other words For example, the gargle bowl 9 is placed in front of the patient so that the patient can easily gargle.

  As described above, in dental treatment, when gargle, the gargle bowl is automatically moved in front of the patient so that the patient can easily gargle, but the rotation position (stop position) of the spit arm 3 is fixed. However, depending on the type of body, such as children and pregnant women, it was too cramped or too far away, making it impossible to respond appropriately.

  The present invention has been made in view of the circumstances as described above. When the automatic rotary arm 3 is used in the spiton device 2, the rotational position of the spiton arm 3 is adjusted in accordance with the patient's body shape, etc. The adjustment position is memorized, and in the subsequent gargle, the spit-arm is automatically rotated to the memorized adjustment position so that the gargle bowl 9 comes to the gargle position suitable for each patient. It was made as a purpose.

  The invention according to claim 1 is a dental treatment chair, a spiton device fixedly disposed on a side of the dental treatment chair, a spiton arm rotatably disposed on the spiton device, and a detachable attachment to the spiton arm In a dental treatment unit comprising a freely gargle bowl, and when the gargle is garnished, the spittone arm is pivoted so that the spittoon bowl is adjusted to a position that is easy for the patient to gargle. A memory for storing a position; and a sensor for detecting that the cup for gargle is lifted, and the spittoon bowl is rotated to a position where it is easy to gargle. The rotation position of the bowl is stored, and thereafter the spitton bowl is automatically stopped at the stored rotation position when gargling. A.

  The invention of claim 2 is characterized in that, in the invention of claim 1, the rotational position stored in the memory is erased when the patient gets off the dental treatment chair.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, the spit arm has a placement portion for the gargle cup and a water supply pipe for supplying gargle water to the cup. The tube is provided with a non-contact sensor for detecting that the cup has been lifted.

  Once the gargle bowl's gargle position has been adjusted and stored according to the patient's body shape (after the last position has been stored), the gargle bowl will have its adjusted and stored gargle position (after the last position is stored) It is automatically moved to the last position), so you don't have to worry about adjusting your posture every time you gargle or adjusting the position of the gargle bowl. I can get it.

In the dental treatment unit shown in FIG. 1, when the patient sits on the dental treatment chair 1, the spit arm 3 usually rotates and the gargle bowl 9 rotates in front of the patient, and the gargle cup 8 is supplied with the water supply pipe. 3 Gargle water is poured from ₁ . The patient picks up the gargle cup 8 and gargles. Conventionally, as described above, the rotational (moving) position of the spit arm 3 is fixed and fixed regardless of the patient's body shape, etc. Depending on the patient's body shape, such as a pregnant woman, the assistant may be cramped or too far away from the optimal position, and the assistant manually adjusts the optimal position. Moreover, the adjustment of the rotational position of the spit arm 3 must be performed every time the patient gargles, which is very inconvenient.

  The present invention has been made in order to eliminate the drawbacks of the prior art as described above. Specifically, in a dental treatment unit using an automatic rotating arm 3 in a spiton device, For example, by attaching a rotary encoder, the rotational position of the spit arm 3 (gargle bowl) is memorized, and thereafter, the spit arm 3 is rotated to the memorized position to provide a gargle position suitable for each patient. Therefore, the rotational position of the spit arm 3 is detected by detecting, for example, the presence or absence of the water supply cup 8 with an ultrasonic sensor attached to the water supply pipe 7, and the position when the cup is lifted is stored as the last position of the gargle pot 9 Thereafter, the spit-on arm 3 is rotated to this storage position.

  The means for detecting and storing the rotation of the spit-on arm 3 is not limited to the rotary encoder, and can be performed using any known desired detection / storage means, and that the cup 8 has been lifted. The detecting means is not limited to the ultrasonic sensor, and any known desired non-contact means can be used.

  When the treatment is finished, the patient descends from the dental treatment chair 1. At this time, since the treatment chair 1 is lowered to the lowest position so that the patient can easily get down, the treatment chair 1 is lowered to the lowest position. Then, the rotational position stored in the storage means is reset (erased) to prepare for the next patient, and thereafter, the rotational position of the spit arm suitable for the next patient is determined in the same manner.

It is a block diagram for demonstrating an example of the dental treatment unit to which this invention was applied or was applied.
