Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blood pressure measuring cuff, and more particularly to an ABPM (Ambulatory Blood Presure Moni) which carries a sphygmomanometer and continuously measures blood pressure in the upper arm.
tor, hereinafter referred to as a continuous blood pressure monitor).

[0002]

2. Description of the Related Art In recent years, when treating hypertension,
It is considered that measurement of only blood pressure at any time measured in a medical institution is insufficient. In other words, only the occasional blood pressure measurement alone cannot avoid the effects of so-called white-coat hypertension, which is pseudo-hypertension caused by the subject's tension, fear, anxiety, and the like. It is pointed out that it is insufficient because it is not possible to prevent hypotension, to detect early-morning hypertension or the like that causes organ damage such as stroke and myocardial infarction.

[0003] To cope with this, a continuous blood pressure monitor that carries a blood pressure monitor at all times and measures blood pressure for 24 hours is becoming widespread. Accordingly, the blood pressure measurement cuff used for the continuous blood pressure monitor must be continuously worn, for example, for 24 hours.

On the other hand, according to the conventional blood pressure measurement cuff, since it is assumed that the blood pressure is measured at any time as described above, the cuff is generally made of a material that is substantially impermeable to gas or liquid, such as an air bag. Have been. However, moisture is constantly evaporating from the skin surface of the upper arm due to skin respiration,
In summer, a large amount of sweat is secreted from the sweat glands in order to keep the body temperature constant.

Therefore, if the cuff for measuring blood pressure is always wound around the skin surface of the upper arm for the continuous blood pressure monitor as described above, moisture at the contact surface between the cuff and the skin surface is reduced. It may become saturated and cause skin damage due to stuffiness and the propagation of various bacteria. In order to prevent such a situation from occurring, a cloth cover that can be easily replaced is attached on the skin contact surface of the cuff skin, and if it becomes dirty, it can be replaced as appropriate, or a replaceable cuff outer structure is adopted. If the cuff outer skin becomes dirty, a cuff for blood pressure measurement has been proposed which is devised such as replacing the entire cuff outer skin.

[0006]

However, replacing the replaceable cover or cuff outer cover in the course of 24 hours as described above hinders continuous measurement, and even if it is performed, the replacement method is not effective. It is necessary to provide explanations and training, and it is quite troublesome work, so that it is difficult to implement.

[0007] In order to perform continuous blood pressure monitoring throughout the 24 hours, the main body of the sphygmomanometer and the cuff are attached to the subject,
Start the blood pressure measurement, repeat the measurement automatically at intervals of 15 minutes, 30 minutes or 60 minutes, remove the body and cuff from the subject 24 hours later, and end the continuous 24-hour blood pressure measurement I have. And, in principle, do not remove the cuff halfway after the start of measurement.
Prevents measurement failure.

When the cuff is re-mounted, the position of the microphone, the winding strength of the cuff, the state of the air tube, and the like must be taken into consideration.

Therefore, the cloth cover and the replaceable cuff outer cover to be mounted on the cuff outer cover are replaced only when they are first mounted on the next subject. not going.

[0010] As a result, even if there is a stuffiness after the cuff is worn, even if there is propagation of various bacteria, the cuff needs to be worn for 24 hours continuously after the start of the measurement, and elderly people with weak skin may suffer from skin disorders. Sometimes. Also, even if there is no stuffiness and no propagation of various bacteria, it will be extremely unsanitary when the measurement is near the end, and if you sweat a lot in the summer, you will also have discomfort due to moisture Will be.

Therefore, the present invention has been made in view of the above-mentioned problems, and for example, even when a cuff is continuously worn for a long time as in a continuous blood pressure monitor, it is possible to prevent the occurrence of stuffiness and to be comfortable. An object of the present invention is to provide a blood pressure measurement cuff that can be used and that can be used hygienically by preventing the propagation of various bacteria.

[0012]

Means for Solving the Problems The above-mentioned problems are solved,
In order to achieve the object, according to the present invention, a cuff outer skin having a contact surface directly touching a measurement site, and a pressurized air bag for bringing the cuff outer skin into close contact with the measurement site, A cuff for measuring blood pressure, comprising: a holding portion for holding the cuff outer skin in a wound state with respect to the upper arm portion, wherein water is absorbed between a surface of the cuff outer skin facing the skin contact surface and the air bag for pressurization. It is characterized by disposing a sex member.
