Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a blood pressure monitor whose operation is automated by an electronic circuit.

[Background Art] As shown in FIG. 5 (Japanese Unexamined Patent Publication No. 60-241421), this type of blood pressure monitor A' has a pressure cuff 1 and a display W#5 integrated together, and a pressurizer for pressurizing the cuff. One example is a configuration in which the pressure pump 2' is integrally provided with the main body casing 6 and the compression band 1, but in this conventional example, the pressure pump 2' presses the compression band 1 from above the compression band 1. This puts pressure on the upper arm, causing pain and having a negative impact on measurement accuracy.

Further, since the pressurizing pump 2' is a manual type and is integrated with the main body casing 6, the pressurizing pump 2' is pushed by the movable plate 31 with the arm opposite to the arm pressurized by the compression band 1. ′ had to be moved, making it difficult to apply force and not being able to pressurize quickly, leading to blood stasis, which also had a negative impact on measurement accuracy. Furthermore, compression band 1
Since the electronic circuit board 4 is placed on the top without intervening other members, the electronic circuit board 4 will not be twisted or twisted by the force that the main body casing 6 receives due to the operation of the pressurizing pump 2' and the expansion of the compression band 1. It was easily deformed due to bending, and the mounted pressure measurement sensor 17 was distorted, which adversely affected pressure accuracy.

[Objective of the Invention] The present invention has been made in view of the above-mentioned circumstances, and its purpose is to improve ease of use (to prevent strain caused by the expansion of the compression band from being transmitted to the electronic circuit board, and to prevent To provide a sphygmomanometer which can reduce measurement errors by absorbing vibrations of a pressure pump into a compression cuff and hardly being transmitted to the outside, and which has good weight balance even though it is an all-in-one type.

[Disclosure of the Invention] The blood pressure monitor of the present invention includes a compression band 1 for pressurizing the upper arm;
An electric pressurization pump 2 for supplying air to the compression cuff 1 to pressurize it, an electronic circuit board 4 provided with an electronic circuit 3 for measuring the pressure inside the compression cuff 1 and determining a blood pressure value, and a blood pressure value. In a blood pressure monitor equipped with a display 5 that displays
, a main body casing 6 housing an electronic circuit board 4 and a display 5 is integrally disposed on the compression band 1, and a pressure pump 2, an electronic circuit board 4, and a display 5 are sequentially arranged on the upper part of the compression band 1. With this configuration, the above objective could be achieved. ! (I) Since it uses the electric front B5 pump 2, it is necessary to operate the pressurizing pump by climbing onto the arm opposite to the arm pressurized by the compression cuff 1, as with conventional manual pumps. In addition, since the electric pressure pump 2, electronic circuit board 4, and display 5 are sequentially arranged above the compression band 1, the electronic circuit board 4 The strain caused by the expansion of the compression cuff 1 is difficult to be transmitted to the compression cuff 1, and the vibration of the electric pressure pump 2 is absorbed by the compression cuff 1, making it difficult to be transmitted to the outside. Since the pressure pump 2 and the electronic circuit board 4 are arranged in this order, the weight balance is good even though it is completely integrated.

The present invention will be described below based on embodiments shown in the accompanying drawings. The compression band 1 consists of a pressure bag 7 and a binding band part 30, and the pressure bag 7 is formed of an inner cloth 8 and an outer cloth 9, and the inner cloth 8 and the outer cloth 9 are elastically opened at the upper part. A curved plate 10 is interposed.

A main body casing 6 consisting of a lower body 6a and an upper half body 6b is attached to the outer periphery of the pressure bag 7 of the compression band 1.
An electric pressurizing pump 2 is engaged with a retaining pawl 12 on one side of the lower half 6a of the main body casing 6, which is integrally attached with a retaining pawl 11 formed on the elastic curved plate 10 at a. It is stopped and placed. The electric pressurization pump 2 is configured to include a diamond-7 ram 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 diamond-7 ram bomb 14. Air is supplied into the pressurized bag 7 by the electric pressurized pump 2 through an air nozzle 16 provided on the outer periphery of the pressurized bag 7. At the lower part of the upper half body 6b, an electronic circuit board 4 is provided with an electronic circuit 3 for determining a blood pressure value from systolic blood pressure value information and diastolic blood pressure value information separately obtained by measuring the pressure within the compression cuff 1. is installed. The pressure measurement sensor 17 mounted on the electronic circuit board 4 is connected to the other end of an air pipe 19 whose one end is connected to a nozzle 18 provided on the outer periphery of the pressure bag 7.

A display IS is attached on one side of the electronic circuit board 4, and this display 5 is attached to the upper half 6 on which the display board 20 is attached.
It is exposed in the display window 21 on the top surface of the panel b. A power switch 26 is provided in the center of the upper half body 6b, and a push button 27 of the power switch 26 projects from the upper surface of the upper cow body 6b. Further, a mounting table 28b is provided on the other side of the upper half body 6b, and together with the mounting table 28a on the other side of the lower half body 6a, a battery storage section 28 is formed, and a battery 29 is placed in this battery storage section 28. The battery contact plate 13 is attached to both ends of the battery via fixing hooks 22. A lid 24 is removably attached to the battery outlet 23 formed in the upper half body 6b with a stopper 25.

To measure blood pressure with this sphygmomanometer A, wrap the compression band 1 around your arm, turn on the power switch 26 by pressing the button 27, and start compressing while watching the pressure display on the display 21. ? i? Increase the pressure inside 1.

After this, the pressure is reduced by a constant speed exhaust mechanism (not shown) housed in the main body casing 6, and at the same time, the blood pressure is measured by the Korotov 7 sound detection sensor (not shown), the pressure measurement sensor 17, etc., and the systolic blood pressure is value, diastolic blood pressure value and pulse rate are automatically displayed on the display 5, and then the air in the compression cuff 1 is evacuated.

[Effects of the Invention] Since the present invention uses an electric pressurization pump, the pressurization pump can be operated by the arm opposite to the arm pressurized by the compression band, unlike the conventional manual type. It is possible to pressurize quickly, so it does not cause congestion and adversely affect measurement accuracy. Since the pump, electronic circuit board and display are installed,
The strain caused by the expansion of the compression cuff is less likely to be transmitted to the electronic circuit board, and the vibrations of the electric pressurization pump are absorbed by the compression cuff and transmitted to the outside. Because the compression band, electric pressure pump, and electronic circuit board are arranged in this order, the weight balance is good even though it is an all-in-one device.
