Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field 1 The present invention relates to a blood pressure monitor, in particular, a blood pressure monitor, in which a main body equipped with a blood pressure value display panel, blood pressure measuring means, etc. is attached to a cuff band that is wrapped around the arm, so that the cuff band and the main body are integrated. This relates to an electronic blood pressure monitor that is said to be

[Background Art 1] What must be kept in mind when measuring blood pressure using an electronic sphygmomanometer is that the Korotkoff sound detection member placed inside the cuff band should be aligned over the artery. Incidentally, a blood pressure monitor in which the main body and the cuff band are integrated has the following problems related to the above-mentioned points. In other words, when measuring blood pressure, place the cuff band 1 on the arm around which the cuff band is wrapped, with the palm facing upward.
At this time, the artery J will be located at approximately 45 degrees on the inside of the arm. On the other hand, the Korotkoff sound detection member disposed within the force 7 band also has a blood pressure value display section and is positioned at approximately 45 degrees with respect to the main body attached to the cuff band. The reason for this is that it becomes impossible to read the blood pressure value displayed by the cuff belt, which is equipped with the display section 10 and the main body 1 to which the pump 5 is connected, as shown in FIGS. 6 and 7. If the positional relationship between the main body 1 and the microphone 20 is determined so that the microphone 20, which is a Korotkoff sound detection member, is located above the artery 9 when the cuff band 2 is wrapped around the right arm, the cuff band 2
When the microphone 20 was placed around the left arm so that the microphone 20 was positioned above the artery 9, the main body 1 turned sideways as shown in FIG. 8, making it impossible to read the display on the display section 10.

[Object of the Invention] The present invention has been made in view of the above points, and its object is to provide a main body having a blood pressure value display section attached to a cuff or a belt, and a cuff belt. To provide a blood pressure monitor which is equipped with a Korotkoff sound detection member and is capable of measuring blood pressure on either the left or right arm with the display direction of the display section facing the measuring person.

DISCLOSURE OF THE INVENTION] The present invention provides a blood pressure monitor in which a main body equipped with a blood pressure value display panel, a blood pressure measuring means, etc. is attached to a cuff band that is wrapped around the arm, and the present invention provides a seven-sound detection system provided in the cuff band. It is characterized by the fact that the members are arranged almost symmetrically around the blood pressure value display section on the main body, and the cuff band is placed on the arm so that the blood pressure display section on the main body faces the person being measured. If the arm is wrapped around the chin, the symmetrical Korotkoff sound detection member will be positioned over the artery, regardless of whether the arm is on the left or right side.

The present invention will be described in detail below based on the illustrated embodiments.
The figure shows one embodiment of the present invention, in which 1 is a main body and 2 is a cuff band. Main body 1 to which pump 5 is connected
A digital display section 10 is provided on the top surface of the device to show the blood pressure value, and blood pressure measuring means as shown in FIG. 2 is provided inside. The cuff band 2 to which the main body 1 is attached has a built-in compression bag 22 connected to the pump 5 through the main body 1, and a pair of microphones 20 as Korotkoff sound detection members.
It has 20. Here, both microphones 20, 2
Microphones 0 are placed in symmetrical positions with the main body 1 at the center; when the cuff band 2 is worn on the right arm, one microphone 2o is placed on the artery 9'', and when the cuff band 2 is placed on the left arm, the other microphone 2o is placed on the artery 9''. A microphone 20 is positioned above the artery 9'.

Since the output of these two microphones 20 and 20 is naturally higher for the one closer to the artery, the one with the higher output is discriminated by the comparison circuit A and only the higher output is detected as shown in Fig. 2. That's what I do. In FIG. 2, B is an amplifier circuit, C is a Korotkoff filter, D is a level detection circuit, E is an operation control circuit, F is an A/D conversion circuit, G is a memory circuit, and H is a circuit for the pump 5 and compression bag 22. The pressure detection sensor connected is a rapid exhaust valve, and J is a constant speed exhaust valve.

A changeover switch for both microphones 20.20 may be provided in place of the comparison circuit A, and the microphone 20.20 connected to the amplifier circuit B may be switched depending on the arm on which the microphone is worn.

FIG. 3 shows another embodiment. Here, microphone 2
Although there is only one 0, a sound collecting cuff 21 is provided in the cuff band 2, and this sound collecting cuff 21 and the microphone 20 are used to
It constitutes a detection member for the F7 sound. As shown in FIG. 4, the sound collection cuff 21 in this detection member is of a bilaterally symmetrical type, with a thick structure on the outer circumference and a thin film sound collecting section on the inner circumference, and is a condenser type microphone. 20 is provided at the center of the outer circumferential side of the sound collecting cuff 21 and is in contact with the internal space of the sound collecting cuff 21, and within the cuff band 2, the sound collecting cuff 21 is located directly below the main body 1, that is, the sound collecting cuff 21 is main body 1
They are arranged symmetrically around the center. Regardless of whether the cuff band 2 is attached to the left or right arm, the artery 9
. FIG. 5 shows another example of the Korotkoff sound detection member, which is composed of a thin film 21 and a piezoelectric microphone 20 glued to the center of the thin film 21, and is similar to the embodiment shown in FIG. 3 above. It is disposed within the cuff band 2 similarly to the Korotkoff sound detection member in .

[Effect of the invention 1 As described above, in the present invention, since the Korotkoff sound detection members are provided almost symmetrically with respect to the main body attached to the cuff band, it is difficult to wrap the cuff band around either the left or right arm. In this way, the Korotkoff sound can be recorded and at the same time the blood pressure value display section on the main body can be directed towards the person being measured.
