BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dental treatment device, and more particularly to a dental treatment device provided with a blood pressure measuring device.

[0002]

2. Description of the Related Art
When a dentist performs dental treatment, when performing certain treatments, for example, tooth extraction with bleeding, it is performed to measure blood pressure, pulse, and the like in advance, and then decide to perform the treatment. In the measurement at that time, it is necessary to take out the blood pressure / pulse measurement device each time, set the arm cuff on the upper arm of the patient, and perform the measurement, and it takes time to take out and store the measurement device,
It was complicated. A finger sphygmomanometer is also commercially available,
In the measurement using this, unless the measurement conditions are kept constant,
There was a problem that the measured values varied greatly.

[0003]

According to the present invention, in order to solve the above-mentioned problems, a finger cuff of a finger sphygmomanometer is arranged on an armrest of a dental chair on which a patient is seated, and measured values are measured by a computer of a main body. The blood pressure measurement operation can be easily performed by simply inserting the fingertip placed on the armrest into the finger cuff arranged in front of the armrest.
As a result, the burden on the dentist and the patient can be reduced, and safe and accurate dental treatment can be performed.

That is, a first invention is a dental treatment chair,
In a dental treatment device comprising a gargling stand, a treatment lighting device and a table, the dental treatment device further includes a main body of a finger sphygmomanometer, a display unit, and the like, and an armrest front part of the dental chair. A finger cuff of a finger sphygmomanometer is provided, and the dental treatment device is further provided with a posture control device for a chair, and inserts a patient's finger into a finger cuff in front of the armrest, thereby forming a patient's heart. A dental treatment apparatus provided with a blood pressure measuring device characterized in that the position and the position of the finger are controlled so as to be at the same level, and the blood pressure is measured. The dental treatment device according to the present invention is a dental treatment device provided with a blood pressure measuring device, wherein a finger cuff is stored in a drawer-type storage portion provided in an armrest portion of a dental treatment chair so that the finger cuff can come and go.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
FIG. 1 is a configuration diagram of a dental treatment apparatus according to an embodiment of the present invention, FIG. 2 is a configuration diagram of another embodiment, FIG. 3 is a diagram showing the arrangement of finger cuffs of the embodiment device, and FIG. FIG. 5 is a block diagram of a sphygmomanometer and a pulse meter, and FIG. 6 is a circuit diagram of a blood pressure and a pulse meter. As shown in FIGS. 1 and 2 (which include a computer main body 21, a floppy disk drive 22, a keyboard 28, and the like), the main components of the dental treatment apparatus are a dental treatment chair 25, a gargle stand 26, It consists of a treatment lighting device 27 and a dental bracket table 15. The dental treatment chair 25 has a built-in hydraulic device (not shown) for controlling the posture of the chair. In the present invention, in particular, the dental treatment chair 25 includes a finger cuff 1 of a finger sphygmomanometer (also including a pulse meter detection unit) in the armrest portion 6 thereof. As shown in detail in FIGS. 3 and 4, the drawer 3 is slidably provided in the armrest 6, and the finger cuff 1 is housed in the drawer 3 so as to be able to come and go. That is, upon measurement, when the drawer 3 is gripped by the knob 5 provided at its lower part and pulled forward, the finger cuff portion 1 which has been inverted and stored as shown by the dotted line in FIG. It is rotated 90 degrees by the force and stands up with the finger cuff support 4 to be in the state shown by the solid line. Therefore, the index finger is inserted into the finger cuff 1 as shown in FIG. In addition, 2 is a signal transmission cable (air pipes are bundled in parallel), and 7 is a long groove.

FIG. 5 is a block diagram for measuring a blood pressure and a pulse, and a detecting section (finger cuff) of the blood pressure and the pulse meter.
1, insertion finger detection system 11, pulse wave information system 12, air pressure control system 13, computer main body 21, display device 20, buzzer 1
4. Floppy disk drive 22, magnetic card I
It comprises an input / output device such as a card reader 22 'for handling C cards. The dentist seats the patient on the dental treatment chair 25 shown in FIGS. 1 and 2 and pulls the knob 5 provided at the lower front part of the armrest 6 of the dental treatment chair 25 as shown in FIGS. The drawer 3 is pulled out forward by the user, and the index finger of the patient is inserted into the finger cuff 1 standing up. At this time, the lower part of the finger insertion part of the finger cuff 1 is parallel to the upper surface of the armrest 6. Thereafter, the dentist tilts the backrest (FIGS. 1 and 2) of the chair 25 backward by the posture control device so that the position of the patient's finger is substantially the same as the patient's heart, and sets the chair 25 to the optimum position. Press the blood pressure / pulse measurement start switch b (FIG. 6) to perform automatic measurement. Thereby, an accurate blood pressure value can be obtained. Further, in this embodiment, the pulse wave information detection amplifier n is installed in the stem close to the finger cuff 1 to improve the S / N ratio, further lower the output impedance, and facilitate extension of the signal transmission cable 2. I have to. Finger cuff 1 after measurement
Is returned to the holder 24 and latched.

FIG. 6 shows a known blood pressure / pulse measurement circuit system. When a finger is inserted into the insertion section 9 in the finger cuff 1, the finger detection element a detects the insertion by an optical signal, When the blood pressure measurement start button (start button) b is pressed, the air pressure system c to g (c: air pressure adjustment valve, d: check valve, e:
A fine exhaust valve, f: quick exhaust valve, g: air buffer) is operated to send air to the finger cuff and press the finger from the surroundings with an appropriate pressure while measuring with the pressure sensor h. Inside the finger cuff, a light emitting element i and a light receiving element k for detecting a blood flow pulse wave of the finger based on the amount of reflected light are provided. Once pressurized, C
When the pressure is gradually reduced by the instruction from the PU 21, pulse wave information proportional to the pressure can be obtained from the light receiving element k.
Predetermined information processing is performed inside the CPU together with the level of the pressure change, and the maximum and minimum blood pressure values and the pulse value are determined,
These values are displayed on the display device 20, and the buzzer 14 for giving necessary instructions in the course of the process is activated. The power source m is obtained by rectifying an AC power source and converting it into a direct current. The air pressure source is supplied from an air pump provided in the dental treatment apparatus. When the displayed measurement data is to be stored in an external memory, the measurement data can be input to a floppy disk (FD) 23 by a floppy disk drive (FDD) 22 and input by a card reader 22 'and stored in a magnetic card, an IC card, or the like. .

[0008]

According to the structure of the present invention as described above, when receiving a dental treatment, the patient firstly sits on the treatment chair and places his / her hand on the armrest portion. Since the finger cuff portion is disposed in front of the finger cuff, the finger cuff may be inserted by sliding the finger into the front finger cuff. Then, the dentist presses the posture control button of the existing dental treatment chair so that the position of the finger in the finger cuff is almost the same level as the patient's heart in order to obtain accurate measurement values, and then starts blood pressure measurement. Accurate blood pressure measurements are easily obtained by pressing the switch. Therefore, the burden on the dentist and the patient can be reduced, and safe and accurate dental treatment can be performed.
