Description

  The present invention relates to a sphygmomanometer cuff that is wound around a living body during blood pressure measurement.

  In recent years, sphygmomanometers are widely used for early detection of lifestyle-related diseases caused by high blood pressure and blood pressure management. Usually, when measuring a blood pressure value, an artery generated in an artery by wrapping a cuff containing a fluid bag for compressing an artery located inside the living body around the body surface and expanding and contracting the wound fluid bag. The pressure pulse wave is detected, and thereby the blood pressure value is measured.

  Here, the cuff means a band-like structure having a lumen, which can be wound around a measurement site (for example, an upper arm or a wrist) of a living body, and a fluid such as gas or liquid is passed through the lumen. It refers to what is used to measure arterial pressure in the upper and lower limbs by infusion. Therefore, the cuff is a term indicating a concept including a fluid bag and a winding means for winding the fluid bag around a living body, and is sometimes called an armband or a manchette.

  Usually, the cuff is provided with an exterior member, and an air bag as a fluid bag is accommodated in the exterior member, and a locking means for winding and fixing the body member around the living body is provided. References disclosing such a cuff configuration include, for example, Japanese Utility Model Laid-Open No. 7-24304 (Patent Document 1), Japanese Patent Application Laid-Open No. Sho 62-213730 (Patent Document 2), and Japanese Patent Application Laid-Open Publication No. 2004-159968 ( Patent Document 3) and the like.

In the cuff for a sphygmomanometer, the cuff is placed on the living body so that the central portion of the air bag in the winding direction around the living body, that is, the longitudinal direction of the cuff when the cuff is deployed, is located immediately above the artery located under the living body. It is preferable to be positioned with respect to and fixed by winding. When the cuff is correctly positioned and wound around and fixed to the living body in this way, the central portion in the longitudinal direction of the air bag, which is the most inflated portion in the thickness direction, and the artery are arranged close to each other. For this reason, the artery can be efficiently and reliably compressed and blocked with an air bag. Therefore, the blood pressure value can be measured with high accuracy.

  However, it is very difficult to position the cuff around the living body after positioning as described above. In particular, in a cuff intended to be wound around the upper arm, when the subject himself / herself needs to wear the cuff around the upper arm, the wrapping operation with only one hand is required, and the positioning operation becomes difficult.

  In order to solve such a problem, a cuff exterior member whose surface is provided with a positioning mark is known. In the cuff, it is intended that the subject positions and wears the cuff with respect to the upper arm so that the mark is positioned on the extension line of the middle finger of the arm on which the cuff is wound. Here, since the brachial aorta is usually located on the trunk side (that is, the chest side) of the upper arm, the central portion in the longitudinal direction of the air bag is spaced a predetermined distance from the mark provided in advance on the exterior member. Are spaced apart.

  However, in general, some cuffs for blood pressure monitors do not allow the air bag to be immovably fixed to the exterior member. This is to make the air bag wound around the living body expand more evenly around the living body. Therefore, in the case where a displacement occurs between the air bag and the exterior member, even if the subject correctly wears the cuff using the mark provided on the exterior member, the central portion in the longitudinal direction of the air bag And the artery are not arranged close to each other, the pressure on the artery is insufficient, and the blood pressure value may not be measured with high accuracy.

  Therefore, the present invention has been made to solve the above-described problems, and an object thereof is to provide a sphygmomanometer cuff in which a fluid bag contained in an exterior member can be reliably positioned with respect to a living body. .

  A sphygmomanometer cuff according to the present invention includes a fluid bag for compressing a living body and a bag-shaped exterior member that encloses the fluid bag, and is provided when the sphygmomanometer cuff is attached to a living body. A positioning mark is provided on the fluid bag, and the mark is configured to be visible from the outside of the exterior member.

  With this configuration, the fluid bag can be attached to the living body while visually recognizing the mark attached to the fluid bag, so that the fluid bag can be reliably positioned with respect to the living body. Therefore, even when a positional shift occurs between the fluid bag and the exterior member, the fluid bag is positioned and arranged at the correct position, so that the blood pressure value can be measured with high accuracy.

  In the sphygmomanometer cuff according to the present invention, the exterior member includes an inner exterior part positioned on the living body side in a state where the sphygmomanometer cuff is attached to the living body, and the inner exterior part sandwiching the fluid bag. The outer exterior part located in the opposite side may be included. In that case, it is preferable that the mark is configured to be visible from the outside on the outer exterior portion side.

  With this configuration, the mark can be visually recognized even after the cuff is attached to the living body, so that fine adjustment after the attachment can be easily performed. Therefore, the positioning operation can be facilitated.

  In the sphygmomanometer cuff according to the present invention, it is preferable that the outer exterior portion of the portion corresponding to the mark is transparent or translucent.

  In the sphygmomanometer cuff according to the present invention, it is preferable that the outer exterior portion of the portion corresponding to the mark is mesh-shaped.

  In the sphygmomanometer cuff according to the present invention, it is preferable that the outer exterior part has a visual window part in a part corresponding to the mark.

  By adopting any one of the above-described configurations, it is possible to visually recognize the mark from the outside of the exterior member, and it is possible to reliably position the fluid bag with respect to the living body.

  In the cuff for a sphygmomanometer according to the present invention, the fluid bag is seen from the bag part in a state where the fluid bag is inflated / contracted when fluid enters and exits and the sphygmomanometer cuff is attached to a living body. It may be located on the opposite side of the living body and may include an urging portion that urges the bag portion against the living body by being fixed to the bag portion. In that case, the said mark may be provided in the said urging | biasing part.

  As described above, even when the fluid bag includes an urging portion made of a curved elastic plate (curler) or the like, by providing a mark on the urging portion, it is possible to visually recognize the mark from the outside of the exterior member. Thus, the fluid bag can be reliably positioned with respect to the living body.

  The sphygmomanometer cuff according to the present invention may be intended to be attached to the upper arm, and in that case, if configured as described above, the positioning relative to the upper arm of the fluid bag can be reliably performed. Become.

  ADVANTAGE OF THE INVENTION According to this invention, it can be set as the cuff for blood pressure monitors which can position the fluid bag enclosed by the exterior member reliably with respect to the biological body.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the embodiment described below, a sphygmomanometer cuff mounted on an oscillometric upper arm sphygmomanometer that is intended to employ the upper arm of the left arm as a measurement site will be described as an example.

The cuff 150A has an air bag 151 as a fluid bag for compressing the upper arm, and a bag-like cover body 161 as an exterior member for winding and fixing the air bag 151 around the upper arm. The air bag 151 is accommodated in a space provided inside the bag-shaped cover body 161. The detailed structure of the cuff 150A will be described later.

  The cuff 150A and the apparatus main body 110 are connected by an air pipe 140 as a connection pipe. The air tube 140 is made of a flexible tube, one end is connected to a blood pressure measurement air system component 131 (see FIG. 2) provided in the apparatus main body 110 described later, and the other end is the air bag 151 of the cuff 150A described above. It is connected to the.

  FIG. 2 is a functional block diagram showing the configuration of the sphygmomanometer in the present embodiment. Next, with reference to this FIG. 2, the structure of the main functional blocks of the sphygmomanometer in the present embodiment will be described.

  As shown in FIG. 2, a blood pressure measurement air system component 131 for supplying or discharging air to / from an air bag 151 contained in a cuff 150A via an air pipe 140 is provided inside the apparatus main body 110 of the sphygmomanometer 100A. Is provided. The blood pressure measurement air system component 131 includes a pressure sensor 132 that is a pressure detection means for detecting the pressure in the air bag 151, and a pump 134 and a valve 135 that are expansion and contraction means 133 for inflating and contracting the air bag 151. included. In addition, an oscillation circuit 125, a pump drive circuit 126, and a valve drive circuit 127 are provided inside the apparatus main body 110 in association with the blood pressure measurement air system component 131.

  Further, the apparatus main body 110 stores a CPU (Central Processing Unit) 122 for centrally controlling and monitoring each part, a program for causing the CPU 122 to perform a predetermined operation, and various information such as a measured blood pressure value. The memory unit 123, the display unit 114 for displaying various information including blood pressure measurement results, the operation unit 115 operated to input various instructions for measurement, the CPU 122, and power to each functional block. A power supply unit 124 for supply is installed. The CPU 122 also functions as blood pressure value calculation means for calculating blood pressure values.

  The pressure sensor 132 detects the pressure in the air bladder 151 (hereinafter referred to as “cuff pressure”), and outputs a signal corresponding to the detected pressure to the oscillation circuit 125. The pump 134 supplies air to the air bladder 151. The valve 135 opens and closes when maintaining the pressure in the air bag 151 or exhausting the air in the air bag 151. The oscillation circuit 125 outputs a signal having an oscillation frequency corresponding to the output value of the pressure sensor 132 to the CPU 122. The pump drive circuit 126 controls the drive of the pump 134 based on a control signal given from the CPU 122. The valve drive circuit 127 performs opening / closing control of the valve 135 based on a control signal given from the CPU 122.

  FIG. 3 is a flowchart showing a flow of blood pressure measurement processing of the sphygmomanometer according to the present embodiment. Next, the flow of blood pressure measurement processing in the sphygmomanometer according to the present embodiment will be described with reference to FIG. A program according to this flowchart is stored in advance in the memory unit 123 shown in FIG. 2, and the CPU 122 reads out this program from the memory unit 123 and executes it, thereby executing blood pressure measurement processing.

  As shown in FIG. 3, when the subject operates the operation button of the operation unit 115 of the sphygmomanometer 100A to turn on the power, the sphygmomanometer 100A is initialized (step S1). Next, when measurement is possible, the CPU 122 starts driving the pump 134 and gradually increases the cuff pressure of the air bladder 151 (step S2). In the process of gradually increasing the cuff pressure, when the cuff pressure reaches a predetermined level necessary for blood pressure measurement, the CPU 122 stops the pump 134, and then gradually opens the closed valve 135 to open the air bag 151. The cuff pressure is gradually exhausted and the cuff pressure is gradually reduced (step S3), and the cuff pressure is detected in the slow depressurization process of the cuff pressure.

  Next, the CPU 122 calculates blood pressure values (maximum blood pressure value, minimum blood pressure value) by a known procedure (step S4). Specifically, in the process of gradually reducing the cuff pressure, the CPU 122 extracts pulse wave information based on the oscillation frequency obtained from the oscillation circuit 125. Then, a blood pressure value is calculated from the extracted pulse wave information. When the blood pressure value is calculated in step S4, the calculated blood pressure value is displayed on the display unit 114 (step S5). The measurement method described above is based on a so-called decompression measurement method that calculates a blood pressure value by detecting a pulse wave when the air bag is depressurized. It is naturally possible to adopt a so-called pressurization measurement method for calculating the blood pressure value.
