Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a blood pressure measurement cuff band for detecting the pulse sound (pulse waveform) generated in the lower arm by compressing the upper arm.

[Conventional technology]

Conventionally, commonly used blood pressure measurement cuffs were inflated by injecting air into the pressure cuff to compress the upper arm and prevent blood flow. Also, a considerable amount of air had to be injected before a certain amount of pressure could be applied to the upper arm, which took time. In contrast, recently, in order to obtain a constant compression force with a small amount of air supply, the outer periphery of the pressure cuff installation area is covered with a hard plate with curls in a cylindrical shape. Blood pressure measurement cuffs that can control inflation have come into use. In the latter case, the pressure cuff, whose outward expansion is regulated by a hard plate, inflates only in the direction of compressing the upper arm, making it possible to achieve blood ischemia with a smaller amount of air injection than in the former case. However, since the amount of air accommodated is extremely small, the starting and ending points of the pulse sound in the lower arm, which occurs during the process of gradually releasing the air inside the pressure cuff and lowering its internal pressure, are difficult to measure. There was a problem that the interval between the two times became too short, making it impossible to accurately obtain blood pressure values.

[Purpose of invention]

This idea was developed to solve the above problems, and was designed to compress the upper part of the upper arm with a small amount of air supply, and to measure blood pressure so that there was a sufficient interval between the start and end points of the pulse sound (pulse waveform). The purpose is to provide cuff bands for

[Structure of the idea]

This invention provides a blood pressure measurement cuff band in which the outer surface of the installation area of the pressure cuff is covered with a cylindrical curly hard plate to prevent the pressure cuff from expanding outward. The outer end portion corresponding to the lower part of the upper arm is provided with a stepped portion that expands outward, so that the above object can be achieved.

〔Example〕

Next, this invention will be explained based on an embodiment shown in the accompanying drawings.

Reference numeral 1 denotes a cuff band main body, and the cuff main body 1 may be manufactured by any method, but in this example, a fabric having countless loops on the front surface and a synthetic resin film formed on the back surface is used as a fabric for the human body. An outer cloth 2 of a predetermined width cut to a length that can be wrapped around the upper arm a about one and a half times, and an inner cloth 3 of the same width made of the same material as the outer cloth 2 and cut to a length that can be wrapped around the upper arm a about one and a half times. These are stacked with one edge aligned so that the synthetic resin surfaces face each other, and a soft synthetic resin sheet 4 having a length that can circumferentially wrap around the upper arm a more than half way is sandwiched between them, and the periphery of these three The one manufactured by welding is shown. When manufacturing the cuff belt main body 1 using such a method, the space formed between the soft synthetic resin sheet 4 and the inner fabric 3 becomes the pressure cuff 5 as it is, which simplifies manufacturing and reduces costs. can be expected. Of course, two soft synthetic resin sheets 4 may be interposed between the outer cloth 2 and the inner cloth 3, and the pressure cuff 5 may be formed between the soft synthetic resin sheets. A pre-manufactured cloth may be interposed between the outer cloth 2 and the inner cloth 3.

Reference numeral 6 denotes a tube for injecting and discharging air into the pressure cuff 5. When the cuff body 1 is manufactured as described above, the tube 6 has its end 6' cut in advance.
It is inserted into the joint between the soft synthetic resin sheet 4 and the inner cloth 3, and is welded at the same time as these. However, even if the tube insertion portion is left in place during the welding, the tube 6 is inserted into the left portion, and that portion is welded later, the same result will be obtained. Although the drawing shows two tubes 6, one tube may be used depending on the pressure gauge used.

Reference numeral 7 denotes a hard plate inserted into the space between the soft synthetic resin sheet 4 and the outer cloth 2 so as to cover the outer surface of the installation area of the pressure cuff 5 of the cuff band main body 1, and the hard plate 7 has a cylindrical shape. A stepped portion 7' is provided with a curl and expands outward at the outer end corresponding to the lower part of the upper arm.
will be established. Insertion of this hard plate 7 maintains the pressure cuff installation area in a cylindrical shape with a larger diameter on the outer end as shown in FIGS. 1 and 3, making it easier to wrap around the upper arm a, and I'm trying not to put too much pressure on it. When manufacturing the cuff band main body 1 as described above, this hard plate 7 will be inserted into the relevant part during welding.

Reference numeral 8 denotes a fastener attached to the inner surface of the other end of the outer cloth 2, and the fastener 8 is a fabric (so-called velvet fastener) having numerous hooks that can be hooked to loops on the surface of the outer cloth 2. ), the cuff band main body 1 wrapped around the upper arm can be fixed in that wrapped state.

Reference numeral 9 denotes a microphone, which is inserted into the space between the enlarged outer end of the hard plate 7 and the soft synthetic resin sheet 4 in the drawing, but a pocket is made on the outer surface of the inner fabric and inserted into the pocket. Alternatively, if the pressure cuff is made of two soft synthetic resin sheets interposed between the outer fabric and the inner fabric, a pocket is made between the pressure cuff and the inner fabric and the pocket is inserted into the pocket. You can. The microphone 9 is used to transmit the pulse sound to the blood pressure monitor, and the pulse sound is recognized by an oscillometric blood pressure monitor or stethoscope that determines the blood pressure value by directly recognizing changes in the waveform of the pulse wave. It is not necessary when using a standard blood pressure monitor. 10 is a manual pump for supplying and exhausting air into the pressure cuff.
This is not necessary if an electric pump is built into the blood pressure monitor. 11 is a blood pressure monitor.

In the embodiment described above, the installation area A of the pressure cuff 5 of the cuff band main body 1 is wrapped around the upper arm and fixed with the outer garment 8, and then air is supplied into the pressure cuff 5. The inflation force of the pressure cuff 5, which is inflated by this air supply, is regulated by the hard plate 7 on the outer surface of the upper arm side, and is released on the lower arm side. That is, after a certain internal pressure is obtained inside the pressure cuff 5 at a portion corresponding to the upper part of the upper arm, the excess air is transferred to a part corresponding to the enlarged lower part of the upper arm, which can also be expanded outward. It can be stored here. Therefore, in addition to the amount of air necessary to ischemize the upper arm, the pressure cuff contains a certain amount of surplus air, and as the evacuation is performed from that surplus air, it can take a correspondingly longer time. becomes.

[Effect of idea]

As described above, this invention is a cuff band for blood pressure measurement in which the outer surface of the installation area of the pressure cuff is covered with a hard plate with curls in a cylindrical shape to prevent the pressure cuff from expanding outward. Since the hard plate is characterized by having a stepped portion expanding outward at the outer end corresponding to the lower part of the upper arm, a blood ischemic effect can be obtained by supplying a small amount of air, while the lower part of the upper arm that occurs during the exhaust process can be This provides an excellent effect in that the detection interval between the start point and end point of the pulse sound (pulse waveform) is sufficient, and the blood pressure value can be accurately obtained.
