1 is a block diagram showing a configuration of an embodiment of the present invention, in which a patient seating confirmation means 1, a biological information measuring means 2, a reference value setting means 3, and a biological information change amount measurement are shown. Means 4, determination means 5, treatment means 6, treatment / diagnosis confirmation means 7 are provided, and further correction means 8 and recording means 9 are provided.

The patient seating confirmation means 1 detects that the patient is seated on the treatment chair, and the living body information measuring means 2 starts measuring the change of the living body information for the patient by this detection. The patient seating confirmation means 1 is provided on a treatment chair or a treatment unit in the vicinity thereof, and is an automatic switch for turning on the switch by sensing the body temperature or weight of the patient, or a manual operation for turning on or off by an operator or the like. Switches and other switches can be used. Further, as the patient seating confirmation means 1, it is possible to use an air bag sensor which will be described later and is capable of detecting the seating of the patient by being set in the patient chair.

The biological information measuring means 2 is a means for measuring changes in the biological information of the patient during dental treatment. Here, the dental treatment is a concept including both dental treatment and dental diagnosis. As dental treatment, conservative treatment such as cutting, filling and impression of teeth, oral surgery such as tooth extraction, periodontal treatment such as scaling (scaling), endodontic treatment such as root canal treatment of teeth, and dental treatment. Orthodontic treatment, esthetic treatment such as whitening, and preventive dental treatment such as oral hygiene guidance are included. The dental diagnosis includes inquiry, electric dental pulp diagnosis, cytology, blood test, bacterial test, counseling for treatment plan, and the like. In any of these dental treatments and dental diagnoses,
The biometric information of the patient changes, and the change of the biometric information is measured.

The biometric information measured by the biometric information measuring means 2 is preferably information that greatly changes during dental treatment and dental diagnosis. For example, the following information is measured alone or in combination. The biometric information to be measured is arbitrarily selected according to the patient, and thus is selected according to the age, height, weight, sex, etc. of the patient. (1) Change in pressure For example, a hand grip provided with a strain element is held by the patient's hand, and a change in grip pressure on the hand grip is amplified by a strain amplifier and detected. (2) Change in physical displacement amount For example, the displacement amount in which the patient tilts the handgrip held by the patient left and right or front and back is detected. (3) Change in respiratory rate, change in heart rate These pieces of information can be measured using an air bag sensor. The air bag sensor is, for example, Japanese Patent No. 324263.
As disclosed in No. 1, it has a structure in which detection elements such as an omnidirectional microphone and a pressure sensor are set in a flexible air bag in which air is enclosed. The respiratory rate, respiratory waveform, and heart rate can be measured by detecting the air pressure when the human body is on the air bag sensor. Therefore, by attaching the air bag sensor to the seat, back or headrest of the treatment chair and seating the patient on it, changes in respiratory rate, heart rate, or respiratory waveform during dental treatment or dental diagnosis are performed. Can be measured. (4) Muscle Tonicity A detection clip is attached to the palm or finger of the patient, and a change in current in the muscle of the patient is detected via the palm or finger based on a signal from the detection clip. (5) Change in skin potential An electrode is attached to the palm or finger of the patient to detect a change in potential. (6) Sweat Amount on Palm or Finger The change in sweat amount generated from the body of the patient such as the palm or finger is detected. (7) Blood Pressure Fluctuation The blood pressure of a patient undergoing dental treatment is measured and the fluctuation is detected.

The present inventor has pursued the relationship between the amount of sweat of a patient and stress during dental treatment and dental diagnosis as follows.

The probe of the continuous sweating rate recording apparatus was attached to the left thumb of the patient with a double-sided tape and fixed by winding the tape from above. As a device for continuously recording the amount of local sweating, a trade name "Kenz-Perspiro OSS-1" is used.
00 "(manufactured by Suzuken Co., Ltd.) was used. In addition, the treatment chair was placed in a horizontal position during the cutting of the teeth to make it as relaxed as possible. Under such conditions, sweating due to changes in physical condition and stress during cutting of teeth is mainly observed. Then, when pain was felt during the diagnosis with the electric pulp medical device for judging the life or death of the tooth, the operator was informed that he / she felt pain (stress) by moving the right hand without the probe. As a result of measuring the amount of perspiration at this time by the above-mentioned device, the patient's pain and the amount of perspiration corresponded well. Therefore, the amount of perspiration from the palm in the above item (6) can satisfactorily correspond to changes in the physical condition of the patient and the presence or absence of stress.

The measurement by the biological information measuring means 2 is
Do this with the patient seated in the treatment chair. In this case, you may go with the backrest of the treatment chair raised,
It is preferable that the patient is relaxed by tilting the backrest so that the patient is substantially horizontal, because this allows sensitive changes in the patient's physical condition to be detected.

The reference value setting means 3 is the biological information measuring means 2
It is a means for setting a reference value based on the biometric information measured by. When the patient sits on the treatment chair, the above-mentioned biometric information changes, but the numerical value of the biometric information in a stable state in which the change is small is used as a reference. In this way, by measuring the sitting state on the treatment chair, it is possible to set a reference value that matches the physical condition of the patient during dental treatment.

The biometric information change amount measuring means 4 is a means for measuring the change amount of the biometric information of the patient during dental treatment. During the dental treatment or the dental diagnosis, the biological information of the patient changes greatly, and only the reference value set by the reference value setting means 3 can accurately determine the physical condition change and / or stress of the patient. It is difficult to measure the change amount of the biometric information by the biometric information change amount measuring means 4 and output the measured value to the determining means 5. As the biometric information change amount measuring means 4, the biometric information measuring means 2 described above can be used as it is. Also, the biometric information change amount measuring means 4
The amount of change in the biological information measured by is obtained by adding, subtracting, multiplying, or dividing a numerical value within a certain period of time, an integral value, or a differential value.

The determination means 5 compares the biometric information measured by the biometric information measurement means 2 with the reference value set by the reference value setting means 3 to determine the physical condition change and / or stress of the patient. The determination is made regarding the presence or absence of physical condition change and / or stress of the patient and the degree (magnitude) of physical condition change or / and stress. Then, the measured biometric information is input to the determination unit 5 via the reference value setting unit 3.

The judging means 5 compares the biological information from the biological information measuring means 2 with the reference value from the reference value setting means 3 and also the physical condition of the patient from the change amount from the biological information change amount measuring means 4. Determine changes or / and stress. As a result, even if the numerical value of the patient's biological information greatly increases or decreases during dental treatment or dental diagnosis, it is possible to make a reliable judgment.

When the judging means 5 judges the change in the physical condition of the patient and / or the stress, the treating means 6 carries out the necessary treatment for medical treatment. As the treatment means 6, any one of a notification means for notifying an operator of a physical condition change and / or stress of the patient, a treatment limiting means for reducing or stopping the output of the therapeutic instrument, and a tension relaxing means for relaxing the degree of tension of the patient. Treat with one or more.

As the notification means, for example, blinking of an instrument handpiece light for illuminating a treatment area,
Flashing the surgical unit's operating light, driving the vibrator on the doctor chair, driving the vibrator on the surgeon,
One or more of buzzer alarms and the like are selected.

FIG. 2 shows a handpiece 21 which is a kind of instrument instrument. A bar 22 for cutting teeth is detachably attached to the tip of the handpiece 21, and a handpiece light 23 is arranged in a position close to the bar 22. The handpiece light 23 is
It is used to light up and illuminate the treatment area during the treatment of teeth. By switching the handpiece light 23 from the lighting state to the blinking state, the operator can know the physical condition change and / or stress of the patient during the treatment. This facilitates appropriate treatment by the operator.

FIG. 3 likewise shows an announcement by the handpiece 21. In the handpiece 21 of FIG. 3, a plurality of light emitting lamps 25 such as LEDs are arranged on a grip 24 held by an operator. By turning on the light emitting lamp 25, it is possible to notify the operator of physical condition changes and / or stress of the patient. In this case, a plurality of light emitting lamps 25
By changing the number of lights, you can respond to changes in physical condition and stress.

The surgical light of the treatment unit is operated and turned on by the operator at the time of dental treatment or dental diagnosis, and notification can be made by switching this illumination to blinking.

Further, a vibrator is arranged on the seat of the doctor chair, or a vibrator is attached to the operator's body,
By driving these vibrators, only the operator can be notified. In addition, a buzzer can be placed in the treatment unit and an announcement can be made by the sound of driving the buzzer.

The treatment control means in the treatment means controls the output to the instrument during dental treatment or dental diagnosis. This output control can be performed according to the change in the physical condition of the patient and / or the magnitude of stress judged by the judging means 5. Specifically, the numerical value of the physical condition change or / and stress of the patient is, for example, 20% of the reference value.
If it is large, the output of the instrument can be reduced to, for example, about 50%, and if it is larger than that, it can be controlled by stopping the output to the instrument.

As the tension relieving means, the treatment chair is gently vibrated to relieve the tension of the patient who is seated, an image of entertainment or the like is displayed on a display arranged near the treatment chair, or a speaker is used. Can be done by supplying music from.

The treatment / diagnosis confirming means 7 in FIG. 1 confirms whether or not the dental treatment / diagnosis has been completed. If the end is not confirmed, the treatment by the treatment means 6 is continued.

The correction means 8 in FIG. 1 is a biological information measuring means 2, a reference value setting means 3, and a biological information change amount measuring means 4.
It is also connected to the recording means 9. This correction means 8
After starting the dental treatment in the dental treatment, the biometric information is input from the biometric information measuring means 2. As a result, the correction unit 8 corrects the reference value based on the amount of change in the biological information during dental treatment, and outputs it to the reference value setting unit 3. The reference value setting means 3 determines a change in the physical condition of the patient and / or stress based on the new reference value input from the correction means 8.

In dental treatment, since a treatment instrument such as a turbine of a treatment unit, a micromotor, an electric engine, an ultrasonic scaler, an air scaler, or a laser light cutting machine is driven, the anxiety of the patient increases and the physical condition of the patient increases. Changes and / or stress changes significantly. this is,
It is mainly different from the dental diagnosis that does not use treatment tools, mainly in interviews. Therefore, when compared with the reference value set before the treatment, there is a large difference from the current state.
The correction means 8 corrects the reference value based on the amount of change in the biological information of the patient in such dental treatment. As a result, the determination unit 5 can more accurately determine the physical condition change and / or stress of the patient. In this case, it is possible to set a more accurate reference value by performing the correction in consideration of the type of treatment instrument used for dental treatment. The actuation of the correction means 8 can be started at the same time when the switch of the treatment instrument is turned on by interlocking with the switch of the treatment instrument. Alternatively, the operator may judge and manually turn on the start switch. The correction means 8 can be omitted if it is unnecessary.

In this embodiment, the biological information measuring means 2
The recording means 9 is connected to. The recording unit 9 records, for each patient, the reference value of the biological information in the normal state among the biological information input from the biological information measuring unit 2, and when performing dental treatment or dental diagnosis on the patient, Reference value determining means 5
Output to.

To record the reference value for each patient, the reference value of the biometric information in the normal state of the patient detected at the time of the first medical examination is set as a set with the data relating to the patient from the biometric information measuring means 2 to the recording means 9. It can be done by sending. Then, at the time of the next treatment or diagnosis of the patient, the operator inputs the patient data to the recording means 9, and the recording means 9 outputs the reference value of the biological information related to the patient to the judging means 5. As a result, it is possible to determine changes in physical condition and stress for each patient.

By providing the recording means 9 as described above, the reference values of the physical condition change and stress for each patient are automatically set in the judging means 5, so that the judgment for each patient can be made accurately. It can be done and the response to individual patients can be done quickly. The recording means 9
The reference value recorded in (1) can be updated as appropriate, and thus the reference value according to the progress of the treatment and the type of treatment can be supplied to the determination means 5.

Next, FIG. 4 shows the biological information actually measured by the biological information measuring means 2. In the figure, A is a waveform of an electrocardiogram, B to G are data measured by the air bag sensor described above, B is a raw waveform on the shoulder of the patient, and C is breathing on the shoulder of the patient analyzed from the raw waveform B. Number, D is raw waveform B
Heart rate in the shoulder of the patient analyzed from E, E is the raw waveform in the waist of the patient, F is the respiration rate in the waist of the patient analyzed from the raw waveform E,
G is the respiratory rate at the waist of the patient analyzed from the raw waveform E.
H is the amount of perspiration on the palm, and I and J are the skin potentials.
The unit of the vertical axis is mV.

When the patient takes a deep breath, all of the waveforms are disturbed, but after a certain time (about 10 minutes in FIG. 4) has passed from the deep breath, the waveform becomes steady and stable. The reference value setting means 3 sets the value of each biometric information at the time when the waveform becomes stable as the reference value.

FIG. 5 is a result of measuring the biometric information of the patient when scaling is performed in the same manner as in FIG. 4, and A to J are biometric information corresponding to FIG. Disturbances are generated in the waveforms A to H due to toothache stimulation based on the removal of tartar. By comparing the values of these biometric information with the reference values set in FIG. 4, changes in the physical condition of the patient and / or stress The presence or absence can be determined.

FIG. 6 shows a flowchart for setting the reference value. When the patient sits on the treatment chair (step S1),
The patient seating confirmation means 1 confirms seating, and turns on the seating signal (step S2). Then, the biological information measuring means 2 measures the biological information of the patient (step S3), and the reference value setting means 3 sets the reference value. In the next step S4, it is determined whether or not the reference value is set, and if the reference value is set, the procedure shifts to the dental treatment of FIG.

When the reference value is not set, it is determined whether or not the measured value of the biological information has increased (decreased) (step S5). When the measured value has not increased or decreased, the above-mentioned reference value is set (step S6), and the process returns to step S3 to measure the biometric information. If the measured value has increased or decreased, relaxation is given (step S
7). The relaxation is given by, for example, supplying music, gently vibrating the treatment chair, or displaying an image on the display, and the process returns to the biological information measurement in step S3.

FIG. 7 shows a flow chart of dental treatment. In step S11, dental treatment is started, and then step S1.
At 2, the dental examination is started. In the dental treatment, information such as the type of treatment instrument used for the treatment is input to the correction means 8 (step S18), and the correction means 8 uses the reference value / value based on this information.
The increase / decrease value is corrected (step S13). Then, in step S14, it is determined whether or not the treatment means 6 is driven. If it is necessary to drive the treatment means 6, the treatment means 6 is driven (step S15), and the process proceeds to step M. If it is not necessary to drive, the process directly proceeds to step M.

In the dental diagnosis in step S12, it is determined whether or not the treatment means 6 is driven. If it is necessary to drive the treatment means 6, the treatment means 6 is driven (step S16),
If it is not necessary to drive in step M, the process directly proceeds to step M.

FIG. 8 shows a concrete example of a dental treatment apparatus to which this embodiment is applied. A treatment chair 1 including a seat portion 11a, a backrest portion 11b, and a headrest 11c.
1, a display 12, a spittoon 18, an operating light 16, and an instrument hanger 14 are arranged around 1, and an instrument 13 is hung on the instrument hanger 14. Driving of the instrument 13 is started and stopped by a foot switch 15.
Reference numeral 17 is the surgeon's doctor chair.

In this dental treatment apparatus, the treatment chair 11,
The display 12, the instrument 13, the foot switch 15, the operating light 16, and the doctor chair 17 are connected to the control computer 20 by wire or wirelessly. An air bag sensor (not shown) is attached to the treatment chair 11 to detect the sitting of the patient, measure the breathing rate and the heart rate of the sitting patient, and output the data to the control computer 20. . Thereby, the control computer 20 determines the physical condition change and stress of the patient.

When the physical condition change or stress of the patient is judged, the control computer 20 controls any one of the display 12, the instrument 13, the foot switch 15, the shadowless lamp 16 and the doctor chair 17. For example, the display 12 is controlled so as to display an image to promote the relaxation of the patient's tension. Instrument 13,
The foot switch 15 is controlled to reduce output or stop.

Further, the control computer 20 controls the handpiece light 23 (see FIG. 2) of the instrument 13 and the shadowless lamp 16 so as to blink them. The lighting control of the light emitting lamp 25 (see FIG. 3) of the instrument 13 is performed. For the doctor chair 17, the vibrator attached is driven. By these operations, it is possible to notify the operator of physical condition changes and tresses of the patient.

In the above embodiment, the biological information measuring means 2 measures the physical condition change and stress of the patient who is undergoing dental treatment or dental diagnosis, and the judging means 5 makes a judgment by comparing with a reference value to determine whether the physical condition is excessive. When it is determined that there is a change or excessive stress, the treatment means 6 performs a predetermined treatment. Therefore, the pain of the patient can be alleviated or eliminated. In addition, since it is possible to objectively judge changes in physical condition and stress of the patient without depending on the subjectivity of the operator, delays in judgment and misjudgment are reduced, and changes in physical condition and stress of the patient on the operator side are reduced. Is no longer necessary, and the operator can concentrate on the treatment.

The present invention is not limited to the above embodiment and can be variously modified. For example, it is possible to measure a change in the biometric information of the patient by the biometric information measuring means and determine the physical condition change or / and the stress of the patient based on the biometric information. In this case, it is not necessary to set the reference value. Further, the physical condition change and / or the stress of the patient may be determined based on the biological information of the patient measured by the biological information measuring means, and the treatment necessary for medical treatment may be performed based on the determination result.

[0068]

As described above, according to the present invention,
Since the patient's excessive physical condition change and stress are objectively judged, accurate judgment is possible, and since the operator's subjectivity is not relied upon, judgment delays and judgment errors are eliminated. Moreover, since it is unnecessary for the operator to sense the physical condition change and stress of the patient, it is possible to concentrate on the treatment and perform safe dental treatment.
