Description

  The present invention relates to a cuff for a sphygmomanometer (hereinafter simply referred to as a cuff) that is used by being worn on an upper arm for measuring a blood pressure value, and a sphygmomanometer including the same.

  Normally, when measuring blood pressure, a cuff containing a fluid bag is wrapped around the body surface of the living body, and the wrapped fluid bag is expanded and contracted to detect arterial pressure pulse waves generated in the artery located inside the living body. The blood pressure value is measured based on this. Here, the cuff means a band-like structure having a lumen and can be wound around a part of a living body, and a fluid bag is inflated by injecting a fluid such as gas or liquid into the lumen.・ It refers to those that are contracted and used to measure blood pressure. In general, the upper arm is often used as the part to be measured of the living body to which the cuff is attached, and the cuff used by being wound around the upper arm is also called an armband or a manchette.

  When measuring the blood pressure value, it is preferable that the upper arm as the measurement site to which the cuff is attached is stably supported. This is because stable movement of the upper arm makes it difficult for body movement to occur in the upper arm, and as a result, an error is less likely to occur in the measured blood pressure value. For this reason, various sphygmomanometers having an upper arm support that can support the upper arm have been devised.

  As a sphygmomanometer equipped with an upper arm support, the cuff and the main body are separated, and the cuff and the main body are integrated with the cuff provided with the upper arm support base, and the cuff is integrated. In some cases, the main body is provided with an upper arm support. In a sphygmomanometer in which the cuff and the main body are separated, the main body is provided with an expansion / contraction mechanism (usually a pressure pump, an exhaust valve, etc.) for expanding and contracting an air bag as a fluid bag contained in the cuff. The air bag contained in the cuff and the expansion / contraction mechanism provided in the main body are connected by a flexible air tube. On the other hand, in a sphygmomanometer in which the cuff and the main body are integrated, a hollow opening for inserting the upper arm is formed in the main body, and the cuff is attached to the main body so as to surround the hollow opening.

  In a sphygmomanometer having a configuration in which the cuff and the main body are separated, the cuff can be made relatively small by separating the cuff from the main body, so that the cuff and the main body can be made excellent in storage properties. It is possible to make it easy to use even under various usage environments.

On the other hand, in a sphygmomanometer in which the cuff and the main body are integrated (see, for example, JP-A-2005-237427 (Patent Document 1)), the cuff is provided with a drive mechanism for winding the cuff. The body can be provided relatively easily, and the cuff can be attached and the blood pressure value can be automatically measured simply by inserting the measurement site into the hollow opening provided in the body. Therefore, it can be said that the sphygmomanometer in which the cuff and the main body are integrated is excellent in that the cuff can be attached and detached very easily.

At that time, the elbow 201 on the right hand is placed on the elbow rest surface 81a of the elbow rest 80 so that the upper arm 200 is stably supported by the upper arm support surface 31a. Next, a portion near the other end of the arm band 40 located outside the upper arm 200 of the right hand as viewed from the subject is grasped with the left hand, and this is pulled out toward the inside of the body and wound around the upper arm 200. A hole 42 provided in the arm band 40 is hooked on a hook 36 (see FIG. 1 and the like) provided in the upper arm support base 30. At that time, the surplus portion of the armband 40 is wound up by the winding mechanism provided inside the upper arm support base 30, so that the armband 40 is tightly wound around the upper arm 200 of the subject's right hand.

  FIG. 9 is a flowchart showing a flow of blood pressure value measurement processing of the sphygmomanometer according to the present embodiment. Next, the flow of blood pressure value measurement processing in the sphygmomanometer according to the present embodiment will be described with reference to FIG. The program according to this flowchart is stored in advance in the memory unit 12 shown in FIG. 2, and the blood pressure value measurement process is performed by the control unit 11 reading and executing the program from the memory unit 12.

  First, as shown in FIG. 9, a subject wearing the cuff 20 on either the upper arm 100 of the left hand or the upper arm 200 of the right hand (see FIG. 7 or 8) operates the operation unit 16 of the sphygmomanometer 1A to turn on the power. Is input from the power supply unit 18 to the control unit 11 as a power source, thereby driving the control unit 11 and initializing the sphygmomanometer 1A (step S101). Next, the control part 11 starts pressurization of the air bag 45 for blood pressure value measurement (step S102). Specifically, the control unit 11 drives the pressurizing pump 61 to increase the cuff pressure, and pressurizes the air bag 45 so as to obtain a predetermined cuff pressure.

  Next, the control part 11 starts the slow depressurization of the air bag 45 for blood pressure value measurement (step S103). Specifically, the control unit 11 stops driving the pressurizing pump 61 and then gradually opens the exhaust valve 62 while controlling the opening amount of the exhaust valve 62. At that time, the control unit 11 acquires the fluctuation of the cuff pressure detected by the pressure sensor 63.

  Next, the control unit 11 calculates a blood pressure value based on the variation of the cuff pressure obtained in the slow depressurization process (step S104). Subsequently, the control unit 11 opens the air bag 45 (step S105). Specifically, the control unit 11 completely opens the exhaust valve 62 and exhausts the air in the air bag 45 to the outside.

  Next, the control unit 11 outputs the blood pressure value obtained in step S104 to the memory unit 12 and the display unit 14, and the blood pressure value is stored as a measurement result in the memory unit 12 (step S106). The blood pressure value as the measurement result is displayed (step S107). Here, the display unit 14 displays the systolic blood pressure value and the diastolic blood pressure value as numerical values, for example. After recording and displaying these blood pressure values, the sphygmomanometer 1 </ b> A takes a standby state and waits for an input of a power-off command from the operation unit 16 of the subject, and stops supplying power as a power source.

  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.

  In the cuff 20 according to the present embodiment described above, the mounting position of the cuff 20 suitable for the upper arm 100 of the left hand and the right hand are changed by changing the mounting position of the elbow rest 80 with respect to the upper arm support 30.

If the arm band 40 is pulled out from the inside to the outside of the body, the hole 42 provided in the arm band 40 is provided on the other side of the upper arm support 30. It is very difficult to perform the operation when the hook 36 is locked. This is because the above-described locking operation is required on the outer side of the arm on which the cuff 20 is attached with the hand on which the cuff 20 is not attached, and the body needs to be largely twisted. However, the cuff 20 according to the present embodiment is provided with the armband outlet 31d in both cases where the cuff 20 is attached to the upper arm 100 of the left hand and when the cuff 20 is attached to the upper arm 200 of the right hand. In addition, since the upper surface side end portion of the upper arm support base 30 is arranged outside the body, the pulling direction of the arm band 40 when the cuff 20 is worn is the direction from the outside of the body toward the inside, It is very easy to use.

  Further, in the cuff 20 in the present embodiment, attachment to the upper arm support base 30 of the elbow rest base 80 is realized by the connection pins 81b1 and the connection holes 31b1 and 31c1 provided thereon. If comprised in this way, it is possible to change the attachment position with respect to the upper arm support base 30 of the elbow rest 80 very easily, and it can be set as the cuff which is very convenient. However, in addition to the attachment structure using the connection pin 81b1 and the connection holes 31b1 and 31c1, various attachment structures such as an attachment structure using a hook-and-loop fastener and a magnet can be used. Needless to say.

  Therefore, by using the cuff 20 as described above and the sphygmomanometer 1A equipped with the cuff 20, the convenience of the sphygmomanometer cuff which does not impair the convenience when the cuff is attached to either the left or right upper arm and A sphygmomanometer equipped with the sphygmomanometer, and by measuring the blood pressure value using the sphygmomanometer cuff and the sphygmomanometer equipped with the cuff, the upper arm is stably supported during the measurement. It becomes possible to measure a blood pressure value with high accuracy.

  Here, referring to FIG. 6, angles θ1 and θ2 formed by a mounting surface 300 such as a table and the upper arm support surface 31a are cuffed when the cuff 20 is attached to the upper arm 100 of the left hand and the upper arm 200 of the right hand. In any case where 20 is mounted, it is preferably 30 ° or more and 60 ° or less. Therefore, in the cuff 20 in the present embodiment, the internal angle θ3 between the first placement surface 33a and the second placement surface 34a is preferably 60 ° or more and 120 ° or less. With this configuration, the angles θ1 and θ2 formed by the mounting surface 300 such as the table and the upper arm support surface 31a are always within a range of 30 ° to 60 °, and the cuff 20 is attached to the upper arm 100 of the left hand. The correct measurement posture can be realized both when worn and when the cuff 20 is worn on the upper arm 200 of the right hand.
