本発明は、健康状態の診断用として病院或いは−ｉ家庭
において使用される血圧計の測定子に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a measuring head of a blood pressure monitor used in a hospital or home for diagnosing health conditions.
血圧測定は、身体のコンデジョンに応じて、また、定期
的に実施して血圧の変化等をヂエツクし健康状態を見る
ために必要なものであるが、これらのチェックを一々病
院へ出向いて行って実施するとなると、傷病者のみなら

なるものである。一方、血圧測定は素人でも比較的簡単
に実施できることから、最近では、一般家庭においても
簡単に扱える血圧測定器が開発され市販されている。Blood pressure measurements are necessary depending on your physical condition and periodically to check for changes in blood pressure and monitor your health condition. If this were to be carried out, it would be extremely burdensome both in terms of time and money, not only for the sick and injured, but also for healthy people. On the other hand, since blood pressure measurement can be carried out relatively easily even by amateurs, recently, blood pressure measuring devices that can be easily used at home have been developed and are commercially available.
しかしながら、現在開示され”ζいるこの種の一般家庭
用血圧測定器は、従来病院等で使用されている血圧測定

圧を確認するようになっている。However, this type of general home blood pressure measuring device currently disclosed is the same as the conventional blood pressure measuring device used in hospitals (a rubber air bag called a cuff is wrapped around the upper arm, and the brachial artery Blood pressure is measured with a blood flow sound detector placed above the air bag.In other words, the brachial artery is temporarily occluded by feeding air into the air bag using a feeding device, and then the air bag is temporarily closed. This method lowers the internal pressure and detects the sound of blood flow. While the sound of blood flow is being detected, this is compared with the display sound or light and the pressure meter reading to determine the systolic and diastolic blood pressure. It is supposed to be confirmed.
従来の血圧測定器では、用具が大きくて携帯に不便であ

正確な血圧測定が難しかった。また、マンシェツトを二
の腕に巻きつけるため、長袖の衣服を着ている場合に、
捲くり上げた衣服の袖によって欠陥が圧迫を受けること
があり、この点によっても、正確な血圧測定ができない
場合がある等の問題点があった。With conventional blood pressure measuring devices, the device is large and inconvenient to carry, and it is extremely troublesome to wrap the sleeve around the upper arm. Because it is difficult to
Accurate blood pressure measurement was difficult. Also, since the manchette is wrapped around the upper arm, if you are wearing long-sleeved clothing,
The defect may be compressed by the rolled-up sleeves of clothing, and this also poses problems such as the inability to accurately measure blood pressure.
本発明はこのような問題点の解消するところの血圧測定
用測定子を提供することを目的としている。It is an object of the present invention to provide a blood pressure measurement probe that solves these problems.
本発明は上記目的を達成するために、柔軟性を有する弾

いる。In order to achieve the above object, the present invention provides a ventilation opening that is made of a flexible elastic material and that is airtightly connected at normal pressure to a pressure receiving part of a pressure meter that displays the pressure of introduced gas by displaying a mercury column or a pointer. The gist of the present invention is a blood pressure measuring probe characterized by having a hollow shape corresponding to the size of a blood vessel to be measured.

て使用者に最高血圧と最低血圧を知らせるのである。As shown in the drawing, the blood pressure measurement probe of the present invention configured as described above can measure the pressure caused by the introduced gas by displaying the mercury column or by using a pointer (
It is used by being installed in the pressure receiving part or pressure sensor part of a pressure meter that displays an analog (analog) or digital display, and is made of an elastic material that is flexible enough to restore its original shape and has a size corresponding to the blood vessel to be measured. Since it has a hollow shape of a certain size and is connected at normal pressure, changes in the compression pressure inside the probe are accurately and quickly transmitted to the pressure gauge, and the probe for blood pressure measurement can be easily transferred to the pressure gauge. It is now possible to accurately press and compress the outside of the blood vessel,
This compresses and occludes the radial artery and other blood vessels to be measured, and then, while gradually relaxing the compression force on the blood pressure measurement probe, the blood flow sound detector detects the blood flow sound. The detected blood flow sound is changed into a display means such as a buzzer to notify the user of the systolic blood pressure and diastolic blood pressure.
以下、本発明を図示した実施例により説明する。 The present invention will be explained below with reference to illustrated embodiments.

The deformation of the measuring head 2 and the change of the pointer 3 are shown.

It is capable of measuring blood pressure, does not require a conventional cuff (a rubber band wrapped around the upper arm), and therefore can measure blood pressure in blood vessels throughout the body with a small device. There is no difficulty in applying it accurately to the blood vessel. Therefore, anyone can easily measure blood pressure. In addition, blood vessel compression and blood flow sound measurement can be performed in a narrow range, and blood pressure can also be measured near the wrist, compared to conventional methods where blood pressure can only be measured near the upper arm. There is no longer any pressure on the blood vessels due to the sleeves of the costume being pulled up, which eliminates cases where blood pressure cannot be measured accurately.
