Description

TECHNICAL FIELD The present invention relates to a sphygmomanometer whose operation is automated by an electronic circuit.

[Background Art] As a blood pressure monitor A'of this type, as shown in FIG. 5 (Japanese Patent Laid-Open No. 60-241421), the compression band 1 and the indicator 5 are integrated and a pressure for pressing the compression band is provided. A configuration in which the pump 2 ′ is integrally provided on the main body casing 6 and the compression band 1 can be mentioned.
In this conventional example, since the pressure pump 2'presses the compression band 1 from above the compression band 1, pressure is applied to the upper arm,
The upper arm was hurt and the measurement accuracy was adversely affected.
Further, since the pressurizing pump 2'is of a manual type and is integrated with the main body casing 6, the movable plate 31 is pushed by the arm opposite to the arm to be pressed by the compression band 1 to press the pressurizing pump 2 '. Since it had to be operated, it was difficult to apply force, and quick pressurization was not possible, leading to congestion, which also adversely affected the measurement accuracy. Furthermore, compression band 1
Since the electronic circuit board 4 is arranged on the upper side without interposing other members, the electronic circuit board 4 is twisted or twisted by the force received by the main body casing 6 due to the operation of the pressurizing pump 2 ′ and the expansion of the compression band 1. It was easily deformed by bending, and the mounted pressure measuring sensor 17 was distorted and adversely affected the accuracy of pressure.

[Object of the Invention] The present invention has been made in view of the above circumstances, and an object of the present invention is that it is easy to use, strain due to expansion of a compression band is not easily transmitted to an electronic circuit board, and pressure is applied. The vibration of the pump is absorbed by the compression band and is difficult to be transmitted to the outside.
An object of the present invention is to provide a sphygmomanometer that can reduce measurement error and that is well-balanced while being an all-in-one type.

The above object was achieved. That is, since the electric pressurizing pump 2 is adopted, it is not necessary to operate the pressurizing pump by the arm opposite to the arm pressurized by the compression band 1 as in the conventional manual type. It enables rapid pressurization, and the compression band 1
Since the electric pressurizing pump 2, the electronic circuit board 4 and the indicator 5 are sequentially arranged on the upper part of the
The strain due to the expansion of the electric pressure pump 2 is difficult to be transmitted, and the vibration of the electric pressure pump 2 is absorbed by the compression band 1 and is difficult to be transmitted to the outside. Since the electronic circuit boards 4 are arranged in order, the weight balance is good even though they are all integrated.

The present invention will be described below based on embodiments shown in the accompanying drawings. The compression band 1 is composed of a pressure bag 7 and a binding band portion 30, and the pressure bag 7 is formed of an inner cloth 8 and an outer cloth 9, and an inner cloth 8 is formed on the upper portion.
An elastic bending plate 10 is interposed between the outer cloth 9 and the outer cloth 9. A main body casing 6 composed of a lower half body 6a and an upper half body 6b is attached to the outer peripheral portion of the pressure bag 7 of the compression band 1 by a locking hook 11 formed on the elastic bending plate 10 in the lower half body 6a. It is attached integrally. On one side of the lower half 6a of the main body casing 6, the electric pressure pump 2 is arranged so as to be locked by a locking claw 12. The electric pressure pump 2 is composed of a diaphragm pump 14 for supplying air to the pressure bag 7 of the compression band 1 to pressurize it and a motor 15 for driving the diaphragm pump 14. Air is sent into the pressure bag 7 by the electric pressure pump 2 through an air nozzle 16 provided on the outer periphery of the pressure bag 7. In the lower part of the upper half 6b, an electronic circuit board 4 provided with an electronic circuit 3 for determining the blood pressure value from the systolic blood pressure value information and the diastolic blood pressure value information separately obtained by measuring the pressure in the compression band 1 Is installed. This electronic circuit board 4
The other end of an air pipe 19 having one end connected to a nozzle 18 provided on the outer peripheral portion of the pressure bag 7 is connected to the pressure measurement sensor 17 mounted on the. A display 5 is mounted on one side of the electronic circuit board 4, and the display 5 is mounted on the display board 20.
It is exposed in the display window 21 on the upper surface of the upper half 6b to which the mounting is performed. A power switch 26 is provided at the center of the upper half 6b, and a push button 27 thereof is projected on the upper surface of the upper half 6b. Further, a mounting table 28b is provided on the other side of the upper half body 6b, and the battery storage section 28 is formed by the mounting table 28a on the other side of the lower half body 6a.
Is formed, and the battery 29 is stored in the battery storing portion 28,
Battery contact plates 13 are attached to both side ends thereof via fixing hooks 22. A lid 24 is detachably attached by a stopper 25 to the battery outlet 23 formed in the upper half 6b.

In order to measure the blood pressure with the blood pressure monitor A, after the compression band 1 is wrapped around the arm, the push button 27 is turned on to turn on the power switch 26, and the compression band is observed while observing the pressure display on the display 21. Increase the pressure in 1. After this, the constant velocity exhaust mechanism (not shown) housed in the main body casing 6 reduces the pressure, and at the same time, the blood pressure is measured by the Korotkoff sound detection sensor (not shown), the pressure measurement sensor 17, etc. to determine the maximum blood pressure value. , The minimum blood pressure value and the pulse rate are automatically displayed on the display 5, and then the air in the compression zone 1 is exhausted.

[Effects of the Invention] In the present invention, since the electric pressurizing pump is adopted, the pressurizing pump is operated by the arm opposite to the arm pressurized by the compression band, as in the conventional manual type. It does not require an operation such as to make it possible to pressurize quickly, so it does not cause congestion and adversely affect the measurement accuracy, and the main body casing has a lower half body and an upper half body. And an indicator and an electronic circuit board are attached to the upper half, and an electric pressure pump and a compression band are attached to the lower half, and an electric pressure pump, an electronic circuit board, and an electronic circuit board are sequentially attached to the upper part of the compression band. Since the display is installed, strain due to expansion of the compression band is difficult to be transmitted to the electronic circuit board,
Moreover, the vibration of the electric pressurizing pump is absorbed by the compression band and is less likely to be transmitted to the outside, improving the measurement accuracy. Furthermore, the main body casing is composed of a lower half body and an upper half body. In addition to mounting the indicator and electronic circuit board on the lower part and attaching the electric pressure pump and compression band to the lower half, the parts are arranged in the order of compression band, electric pressure pump, electronic circuit board. Therefore, it is an all-in-one type and has a good weight balance.
