  Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. In each embodiment, the same member is assigned the same reference numeral.

(First embodiment)
FIG. 1 is a block diagram showing the configuration of the first embodiment of the present invention. The first biological information measuring means 1, the extracting means 2, the judgment level setting means 3, the judgment level switching means 4, the judgment means 5, and the treatment means. 6. A recording means 10 is provided.

  The first biological information measuring means 1 is means for measuring a plurality of biological information from a patient to be treated. As the biological information measured by the first biological information measuring means 1, at least one of the patient's respiratory rate, respiratory waveform, heart rate, heart rate waveform, and body motion is selected. The biometric information can be selected in accordance with patient conditions such as the patient's age, sex, height, and weight.

  The first biological information measuring means 1 measures a plurality of biological information when a patient is sitting on a treatment chair or sleeping on a bed. As the first biological information measuring means 1, an air bag sensor disclosed in Japanese Patent No. 3242631 can be used. The air bag sensor has a structure in which detection elements such as an omnidirectional microphone and a pressure sensor are set in a flexible air bag filled with air. By detecting the air pressure when the human body is on the air bag sensor, the respiratory rate, respiratory waveform, heart rate, heart rate waveform, and patient's body movement can be measured. Therefore, by attaching the air bag sensor to the seat, backrest or headrest of the treatment chair and seating the patient on it, the respiratory rate change, heart rate change, respiratory waveform, heart rate waveform, body Motion can be measured.

  FIG. 2 shows an example in which the air bag sensor 60 is mounted on the treatment chair 50. The treatment chair 50 includes a seat portion 51 and a backrest portion 52, and the air bag sensor 60 is disposed on the seating surface side of the backrest portion 52. The air bag sensor 60 is fixed to a predetermined position of the backrest portion 52 by an attachment belt 53 that spans the backrest portion 52. A tube 62 covered with a signal line is drawn out from the air bag sensor 60, and the tube 62 is connected to a measuring means such as a computer. With such a structure, when the patient attaches or detaches to / from the treatment chair 50, the air bag sensor 60 can contact the patient's back and detect a plurality of biological information from the patient. The air bag sensor 60 may be disposed on the seat portion 51 of the treatment chair 50, or may be disposed between the seat portion 51 and the backrest portion 52. When the air bag sensor 60 is mounted on a medical bed, a plurality of pieces of biological information can be measured from the patient by fixing the air bag sensor 60 to a portion corresponding to the back portion of the patient.

  FIG. 3 shows an example of patient biological information measured by the first biological information measuring means 1 such as the air bag sensor 60 described above. The biological information measured by the first biological information measuring means 1 is a waveform in which biological information such as the patient's respiratory rate, respiratory waveform, heart rate, heart rate waveform, and body motion is combined.

  The extracting means 2 is means for extracting specific biological information from a plurality of biological information (FIG. 3) measured by the first biological information measuring means 1. As the extracting means 2, a band pass filter that passes only a specific frequency can be used. The band-pass filter is incorporated in the computer, and specific biological information is extracted individually by inputting a plurality of biological information from the first biological information measuring means 1 to the computer. Thereby, the specific biometric information required for the patient's stress determination can be obtained.

  FIG. 4 shows a waveform of specific biological information extracted by the extracting means 2, where T1 is a waveform of a patient's heart rate, T2 is a waveform of respiratory rate, and T3 is a waveform of body movement. The specific biological information extracted so as to be independent is input to the determination level setting means 3.

  The determination level setting unit 3 sets the determination level of the patient's stress with respect to the specific biological information from the extraction unit 2 based on a determination criterion preset by a doctor. This setting is made by generating a predetermined number of peaks greater than or equal to a predetermined value within a predetermined time (for example, 3 seconds) in specific biological information (waveform). For example, the level S1 in FIG. 4 is a stress determination level set for the heart rate waveform T1. The determination level can be input by input means such as a computer keyboard that controls the determination level.

  The determination unit 5 is configured to determine the specific biological information (for example, heart rate) set by the determination level setting unit 3 and the specific biological body extracted by the extraction unit 2 so as to correspond to the specific biological information. Compare information (heart rate). The number of peaks exceeding the determination level S1 is set in the determination unit 5 during a predetermined time during medical treatment, and the number of peaks within a predetermined period of the specific biological information of the patient input from the extraction unit 2 is set. When the number of peaks is exceeded, it is determined that the stress is large, and when the number is less than the set number of peaks, it is determined that the stress is small. When it is determined that the stress is large, the determination unit 5 outputs an activation signal to the treatment unit 6. Thereby, the treatment means 6 operates. When it is determined that the stress is small, the determination unit 5 does not activate the treatment unit 6.

  The judgment level switching means 4 is means for switching the judgment level set by the judgment level setting means 3 to a stress correspondence judgment level corresponding to the patient's stress. The determination level switching unit 4 receives the determination level (for example, T1) set by the determination level setting unit 3 and specific biological information corresponding to the determination level from the extraction unit 2. When the number of peaks of the waveform from the extraction unit 2 often exceeds the determination level within a predetermined time (when the patient's stress is large), the determination level switching unit 4 determines the determination level set by the determination level setting unit 3 Is switched to the stress response determination level. That is, the stress correspondence determination level is set to a value smaller than the determination level.

  The level S2 in FIG. 4 is this stress correspondence determination level, and the switched stress correspondence determination level S2 is output to the determination means 5. When the stress correspondence determination level S2 is input, the determination unit 5 interrupts the comparison with the determination level S1, and compares the stress correspondence determination level S2 with specific biological information (for example, T1) from the extraction unit 2. Then, when the peak value of the specific biological information exceeding the stress correspondence determination level S2 within a predetermined time exceeds the set peak number, the stress is determined to be large, and when the peak value is less than the set peak number, the stress is small. Is determined. When it is determined that the stress is large, the determination unit 5 outputs an activation signal to the treatment unit 6. Thereby, the treatment means 6 operates. When it is determined that the stress is small, the determination unit 5 does not activate the treatment unit 6.

  On the other hand, when the number of peaks of the waveform from the extraction unit 2 within a predetermined time rarely exceeds the determination level (when the patient's stress is small), the determination level switching unit 4 determines the determination level set by the determination level setting unit 3 Is switched to a stress response judgment level with a smaller value. Also in this case, the determination unit 5 similarly determines the biological information from the extraction unit 2 using the stress correspondence determination level S2 instead of the determination level set by the determination level setting unit 3.

  As the determination level switching means 4, a manual switching switch may be used. When the doctor who is under medical care looks at the patient's condition and determines that stress such as pain is large, the doctor switches the manual switching switch. It may be operated to switch to the stress correspondence determination level S2. Similarly, when it is determined that the stress is small, it is possible to switch to a stress-corresponding determination level having a small value by operating a manual changeover switch.

  In such an embodiment, the determination level of the patient's stress is set based on specific biological information extracted from the plurality of biological information of the patient, and the determination level is set to the stress correspondence determination level according to the patient's stress. Because of the switching, the patient's stress can be easily and quickly detected according to the patient. Further, it is possible to easily switch to the stress correspondence determination level.

  The recording unit 10 records the determination level set by the determination level setting unit 3 and the stress correspondence determination level switched by the determination level switching unit 4. The determination level and the stress correspondence determination level are recorded for each patient, and when the patient performs medical care, the recording unit 10 outputs these levels to the determination unit 5. Thereby, it is not necessary to set a determination level and a stress correspondence determination level for each patient every time medical care is performed, and quick medical care is possible.

  The treatment means 6 is a means for performing treatment necessary for medical treatment when the determination means 5 determines that the patient's stress is large. The treatment means 6 includes one or more of notification means 13 for notifying the doctor of the patient's stress, tension relaxation means 14 for reducing the degree of tension of the patient, and treatment restriction means 15 for reducing or stopping the output of the treatment instrument. Is used.

  As the notification means 13, display of the judgment level on the display, display of the judgment level on the instrument, blinking of the handpiece light of the instrument that illuminates the treatment site, blinking of the surgical unit's operating light, doctor One or more of driving of a vibrator mounted on a chair, driving of a vibrator worn by a doctor, and a buzzer alarm are selected.

  Examples of the display of the judgment level on the display in the notification means 13 include display on a level meter, LED lighting, numerical display, illumination change and color change display, and character and figure display. it can.

  FIG. 5 shows a handpiece 71 which is a kind of instrument for use in dental care when dental care is selected as medical care. A bar 72 for cutting teeth is detachably attached to the tip of the handpiece 71, and a handpiece light 73 is disposed at a position close to the bar 72. The handpiece light 73 is used to turn on and illuminate a treatment site during tooth treatment. By switching the handpiece light 73 from the lighting state to the blinking state, the doctor can know the stress of the patient during the treatment. Thereby, an appropriate treatment by a doctor is promoted.

  FIG. 6 shows the notification by the handpiece 71 when the medical treatment is similarly a dental medical treatment. In the handpiece 71 of FIG. 6, a plurality of light emitting lamps 75 such as LEDs are arranged on a grip 74 held by a doctor. By turning on the light emitting lamp 75, the stress of the patient can be notified to the doctor. In this case, by changing the number of lighting of the plurality of light-emitting lamps 75, it is possible to cope with changes in physical condition and magnitude of stress.

  The surgical light of the treatment unit is operated and turned on by a doctor at the time of medical treatment, but notification can be made by switching this illumination to blinking.

  In addition, it is possible to notify only the doctor by arranging a vibrator on the seat of the doctor chair or by attaching a vibrator to the operator's body and driving these vibrators. Furthermore, a buzzer can be arranged in the treatment unit, and notification can be given by the sound of driving the buzzer.

  As the tension relieving means 14, the treatment chair is gently vibrated to relieve the tension of the sitting patient, an image such as entertainment is displayed on a display arranged in the vicinity of the treatment chair, or music from a speaker. This can be done by supplying

  The treatment control means 15 limits the output of the treatment instrument during medical treatment. For example, in the case of dental practice, the output to the instrument is controlled. This output control can be performed according to the magnitude of the stress of the patient determined by the determination means 5. Specifically, if the patient's stress value is, for example, about 20% larger than the reference value, the output of the instrument is reduced to, for example, about 50%. The output can be controlled by stopping the output.

  FIG. 7 shows an example in which the medical device of this embodiment is incorporated in a dental treatment device. A display 82, a spitton 88, a surgical light 86, and an instrument hanger 84 are disposed around a treatment chair 81 including a seat 81a, a backrest 81b, and a headrest 81c. The instrument 83 is hung. The instrument 83 is started and stopped by a foot switch 85. 87 is a doctor chair of an operator (doctor).

  In the dental treatment apparatus shown in FIG. 7, a treatment chair 81, a display 82, an instrument 83, a foot switch 85, a surgical light 86, and a doctor chair 87 are connected to a control computer 89 by wire or wirelessly. An air bag sensor (not shown) is attached to the treatment chair 81, detects the sitting of the patient, measures the respiratory rate and heart rate of the seated patient, and outputs the data to the control computer 89. . Thereby, the control computer 89 determines the magnitude of the patient's stress.

  When determining the stress of the patient, the control computer 89 controls any of the display 82, the instrument 83, the foot switch 85, the surgical light 86, and the doctor chair 87. For example, the display 82 is controlled to display an image, and the patient's tension is alleviated. For the instrument 83 and the foot switch 85, output reduction and stop control are performed.

  Further, the control computer 89 controls the handpiece light 73 (see FIG. 5) and the surgical light 86 of the instrument 83 to blink. Lighting control of the light emitting lamp of the instrument 83 is performed. For the doctor chair 87, the attached vibrator is driven. By these operations, the stress of the patient can be notified to the doctor.

(Second Embodiment)
FIG. 8 shows a block diagram of the medical device according to the second embodiment of the present invention. The first biological information measuring means 1, the extracting means 2, the judgment level setting means 3, the judgment level switching means 4, the judgment means 5 and the treatment means. 6, the treatment means 6 includes a notification means 13, a tension alleviation means 14, and a treatment restriction means 15. These configurations are the same as those of the first embodiment described above.

  In this embodiment, evaluation function setting means 21 is provided. The evaluation function setting means 21 is inserted between the extraction means 2 and the determination level setting means 3, and the specific biological information of the patient extracted by the extraction means 2 is input.

  The evaluation function setting means 21 is a means for setting an evaluation value for evaluating a patient's stress based on specific biological information from the extraction means 2. The evaluation value of stress by the evaluation function setting unit 21 is performed by weighting and averaging specific biological information from the extraction unit 2. Next, the setting of the stress evaluation value by the evaluation function setting means 21 will be described.

  In the extraction means 2, a plurality of pieces of biological information from the first biological information measuring means 1 are separated into specific biological information by a band pass filter. For example, as shown in FIG. 4, the extraction unit 2 separates the waveform into a heart rate T1, a respiration rate T2, and a body motion T3. The waveform information is input to the evaluation function setting unit 21.

  The evaluation function setting means 21 multiplies the extracted waveforms of heart rate T1, respiration rate T2, and body movement T3 by weighting factors α, β, γ, and adds these values to extract the extracted waveform. The evaluation value Y is obtained by dividing by the number of. That is, when the values of the heart rate T1, the respiration rate T2, and the body movement T3 at each time are a, b, and c, the evaluation value Y is obtained by calculating Equation (1). The values of the above coefficients α, β, and γ can be set large for important biological information, and can be set small otherwise. The values of the coefficients α, β, and γ are arbitrarily set so that the evaluation value Y is a numerical value in a range that can correspond to the determination level.

  Y = ((a × α) + (b × β) + (c × γ)) / 3 Formula (1)

  By using the evaluation value Y obtained by weighting and averaging a plurality of pieces of biological information in this way, a highly reliable determination can be made.

  The obtained evaluation value Y is output to the determination level setting unit 3, and the determination level setting unit 3 sets a determination level for the evaluation value Y based on a determination criterion preset by a doctor. The set determination level is output to the determination unit 5, and the determination unit 5 determines the magnitude of the patient's stress by comparing with the specific biological information from the extraction unit 2.

  FIG. 9 is a graph showing the relationship between the evaluation value and the determination level in the determination level setting means 3. In FIG. 9, when the determination level exceeds “5” at the boundary of “5”, the determination means 5 determines that the stress of the patient is large, and when the determination level does not exceed “5”, the stress is small. to decide. That is, the magnitude of the stress is determined using the evaluation value “200” as a boundary. FIG. 10 shows the waveform of the evaluation value set by the evaluation function setting means 21. When the peak of the waveform exceeds the determination level of “5”, the determination means 5 determines that the patient's stress is large, and the treatment means 6 outputs a drive signal. Thereby, the notification means 13, the tension relaxation means 14, and the treatment restriction means 15 operate | move similarly to 1st Embodiment.

  The determination level switching means 4 of this embodiment switches the determination level based on the evaluation value set by the evaluation function setting means 21 to obtain a stress correspondence determination level according to the patient's stress. For example, in the evaluation value waveform in FIG. 10, when the waveform peak exceeding the determination level of “5” exceeds a predetermined number (for example, 3 times) for a predetermined time (for example, 1 minute) or significantly exceeds the determination level of “5”. In this case, the determination level switching means 4 switches to the stress correspondence determination level graph shown in FIG. As a result, the evaluation value corresponding to the determination level of “5” is “100”, and the magnitude of the stress is determined using the evaluation value of “100” as a boundary. FIG. 12 shows the evaluation value set by the evaluation function setting means 21, and “100” is a criterion for determining the level of stress of the patient. In this way, the judgment level is lowered by the judgment level switching means 4 switching to the stress correspondence judgment level shown in FIG. For this reason, it is possible to quickly perform treatment for a patient having a constitution sensitive to stress.

  On the other hand, in the evaluation value waveform in FIG. 10, the waveform peak exceeding the determination level of “5” has a predetermined time (for example, 1 minute) less than a predetermined number (for example, 3 times) or exceeds the determination level of “5”. In the case of no waveform, the judgment level switching means 4 switches to the stress correspondence judgment level graph shown in FIG. As a result, the evaluation value corresponding to the determination level of “5” is “256”, and the magnitude of the stress is determined using the evaluation value of “256” as a boundary. FIG. 14 shows the evaluation value set by the evaluation function setting means 21, and “256” is a criterion for determining the magnitude of the patient's stress. In this way, the determination level is increased by the determination level switching means 4 switching to the stress correspondence determination level shown in FIG. For this reason, it can respond to the patient of the constitution strong against stress.

  The above judgment level switching means 4 can be operated also by a doctor's judgment. When it is determined that the patient under medical care has a constitution sensitive to stress (pain), the doctor operates the manual changeover switch to switch to the stress correspondence determination level shown in FIG. Thereby, since the determination level is lowered, as shown in FIG. 12, the determination means 5 determines the magnitude of the stress with the evaluation function of “100” as a boundary. If the doctor determines that the patient is resistant to stress, the doctor operates the manual changeover switch to switch to the stress correspondence determination level shown in FIG. Thereby, since the determination level becomes high, the determination unit 5 determines the magnitude of the stress with the evaluation value “256” as a boundary.

  According to such an embodiment, the evaluation value for evaluating the patient's stress is set based on the specific biological information extracted from the plurality of pieces of biological information of the patient, and the determination level of the patient's stress is set based on the evaluation value. Since this determination level is switched to a stress correspondence determination level corresponding to the patient's stress, the patient's stress can be easily and quickly detected according to the patient. Also, the patient's stress determination level can be determined as a stress correspondence determination. You can easily switch to the level.

The amount of perspiration can be obtained by measuring the change in the amount of sweat generated from the finger of the patient. The degree of muscle tension can be obtained by attaching a detection clip to the patient's palm and fingers and detecting a current change in the patient's muscle. The blood pressure fluctuation can be obtained by attaching SPO2 to the patient's finger. The degree of pain of the patient can be obtained by having the patient have a pain switch and turning on the pain when the patient feels pain.

  The biological information measured by the second biological information measuring unit 23 is input to the evaluation function setting unit 21. Thereby, the evaluation function setting means 21 sets an evaluation function based on the specific biological information from the extraction means 2 and the biological information from the second biological information measuring means 23. FIG. 16A shows patient biometric information data detected by the air bag sensor 60, A and B are SPO2 waveforms, C is a heart rate at the seat in the treatment chair, and D is a seat. , E is the heart rate at the back portion of the treatment chair, and F is the respiration rate at the back portion. G is a pain level, H is input data from a pain switch, and I is a sweating amount. FIG. 16B is a graph of the evaluation value Y by the evaluation function setting unit 21.

The pain switch data is input to the evaluation function setting means 21, and the evaluation function setting means 21 creates a graph of the evaluation value Y shown in FIG. At this time, by setting the evaluation value Y with the weighting coefficient at the time when the pain switch is turned on as a large numerical value, the evaluation value Y can be set to the patient's pain.

  According to such an embodiment, the second biological information measuring means 23 measures biological information different from the biological information of the first biological information measuring means 1, and sets the evaluation value of the stress of the patient based on this. The determination level can be accurately set according to the stress of the patient. In addition, since the judgment level is switched to the stress correspondence judgment level according to the patient's stress, the patient's stress can be easily and quickly detected according to the patient, and the patient's stress judgment level can be determined as the stress correspondence judgment. You can easily switch to the level.
