Description

  The present invention provides a dental treatment unit, more specifically, a treatment chair for a patient, with a function capable of measuring a patient's physiological state (for example, sweat volume, blood pressure, pulse, etc.) and monitors the physiological state. In addition to displaying, when the physiological state exceeds a predetermined value set in advance, the dental treatment instrument used at that time is stopped.

  FIG. 4 is an overall configuration diagram showing an example of a dental treatment unit to which the present invention is applied. In the figure, reference numeral 10 denotes a dental treatment unit, which includes a treatment chair 1, a work table 2, a spiton 3, It consists of a shadow lamp 4, an instrument holder 5, a foot switch 6, an instrument holder 7 for assistants, etc. The instrument holder 5 houses various instruments 8 used in dental treatment, As is well known, in the case of dental treatment, the patient sits on the chair 1 and receives the treatment with his head fixed to the cradle 9. During treatment, the surgeon moves the treatment chair 1 up and down, tilts, tilts, etc., and treats the patient in an easy-to-treat posture.

  During dental treatment, some patients are very tense, sweating, and have physiological abnormalities such as blood pressure and pulse rise, and it is dangerous to continue treatment. However, the conventional dental treatment unit does not have a function of monitoring the physiological state of the patient, and the tension state of the patient has to rely on the operator's senses. However, even the surgeon does not know the normal physiological state of all patients and does not remember how much the tension was at the start of treatment. Furthermore, the amount of sweating, blood pressure, and pulse of the patient at the start of treatment may be slightly higher than the amount of sweating and blood pressure in normal times depending on the degree of tension of the patient.

  In order to know the normal (or before treatment) physiological state of a patient, the blood pressure and pulse rate of the patient have been measured. Is not considered at all, and it may be dangerous to continue treatment.

  The present invention has been made in view of the above circumstances, and in response to a change in an abnormal physiological state of a patient during dental treatment, the instrument being treated is automatically stopped so that the patient's It is designed to keep it safe.

  The patient's dental treatment chair is provided with measuring means for measuring the physiological state of the patient (for example, sweat volume, blood pressure, pulse, etc.), and during the dental treatment, these physiological states are measured and monitored, and these physiological states are determined in advance. The dental treatment tool (instrument) in use is automatically stopped when the value exceeds a predetermined value or when the value changes by a predetermined value or more.

  According to the first aspect of the present invention, there is provided a measuring instrument for measuring a physiological condition of a patient provided in a dental treatment chair, and a measurement value and a measurement condition measured by the measuring instrument prior to the start of dental treatment. An arithmetic device that calculates the maximum physiological state value, and a comparison device that compares the maximum physiological state value of the patient output by the arithmetic device and the physiological state value measured by the measuring device during dental treatment of the patient And a means for stopping the dental treatment tool being used for the treatment when the physiological state value during the dental treatment of the patient reaches the maximum physiological state value of the patient. .

  The invention of claim 2 is the invention of claim 1, wherein the physiological state value of the patient before dental treatment, the maximum physiological state value of the patient by the calculation, and the physiological state value of the patient during dental treatment It is characterized by having a monitor which displays simultaneously.

  The invention of claim 3 is characterized in that, in the invention of claim 1 or 2, the measurement condition is the sex and age of the patient.

  According to a fourth aspect of the present invention, in any one of the first to third aspects of the invention, an alarm sound is generated when a physiological state value during dental treatment of the patient approaches the maximum physiological state value of the patient. It is characterized by that.

  According to the dental treatment unit of the present invention, when a patient's physiological condition becomes abnormally large or changes abnormally during dental treatment, the instrument under treatment is automatically stopped. Accidents due to physiological abnormalities can be prevented, and at the same time, the patient can be reassured. In addition, it helps to avoid misjudgment by the surgeon and reduces the mental burden on the surgeon. it can.

  FIG. 1 is a block diagram of a main part for explaining an embodiment of a dental treatment unit according to the present invention. In the drawing, a part having the same function as the conventional dental treatment unit shown in FIG. The same reference numerals as in the case are attached, and the detailed operation description is omitted. Thus, in FIG. 1, 11 and 12 are elbow supports provided in the dental treatment chair 1. Preferably, the sweating amount measuring device 21 and the blood pressure and pulse measuring devices are provided at the tips of the elbow supports 11 and 12. 22 etc. are provided, and these measured values are displayed on the monitor 23.

FIG. 2 is a block diagram for explaining the operation of the present invention, and FIG. 3 is a diagram showing a display display example on the monitor 23.
In the dental treatment, the patient sits on the dental treatment chair 1, puts his elbow on the elbow receivers 11, 12, for example, grasps the sweat amount measuring device 21 provided at the tip of the left elbow receiver 11 with the left hand, and receives the right elbow receiver 12. When the middle finger is inserted into, for example, a finger insertion hole of the blood pressure / pulse measuring device 22 provided at the distal end of the head, the amount of sweating, blood pressure, and pulse at that time are measured and stored, and are digitally displayed on the display 23c of the monitor 23, for example. (The initial value in FIG. 3 is displayed). In that state, when the patient's sex, age, etc. are input from the operation key 23a provided on the monitor 23 or other arbitrary location, for example, a CPU (maximum physiological state value calculation unit) provided in the monitor 23 23b, the maximum value that the patient can tolerate (value in which the physiological state is recognized to be abnormal) is calculated and stored, and the value is digitally displayed next to the initial value, for example (see FIG. 3). Displays the maximum value).

  Thereafter, during dental treatment, measurement of the amount of sweating of the patient and measurement of blood pressure and pulse are continued, and each time the current measurement value is displayed, for example, digitally (the display of the current value in FIG. 3) next to the maximum value display. The During the dental treatment, the current value changes sequentially, but the value is compared with the maximum value by the comparator 23d. When the value approaches a predetermined maximum value, the measured value approaches the maximum value. When the alarm 24 is sounded or the current value display on the display 23c is flushed to warn that the patient's physiological condition is approaching the critical value, and the current value reaches the maximum value, the instrument stop device 25 Is activated to disable the use of the instrument, such as by disconnecting the power source of the dental treatment instrument (instrument) currently in use.

  After the instrument that is in use becomes unusable, the patient can be relaxed by returning the treatment chair to the upright position, playing music, etc., and the instrument becomes unusable. Or, after a predetermined time has passed, the alarm disappears, and when the current measured value falls below the maximum value, or the current measured value falls close to the initial value, the disabled instrument is Make it available again.

  As is clear from the above description, during the dental treatment according to the present invention, when the physiological state of the patient becomes abnormal, the alarm display is flushed or an alarm sound is generated. (Strument) is automatically stopped, so accidents caused by the patient's physiological abnormalities can be prevented, giving the patient a sense of security, In contrast, it can provide a sense of mental security, reduce the mental burden on the surgeon, and reduce the surgeon's fatigue.
