Description

  The present invention relates to a so-called upper-arm blood pressure measuring device (hereinafter also simply referred to as a sphygmomanometer) in which the upper arm is used as a part to be measured, and in particular, an upper arm configured by separating a main body portion and a cuff portion. The present invention relates to a blood pressure measuring apparatus of the type.

  In recent years, blood pressure monitors have been widely used for early detection of lifestyle-related diseases caused by high blood pressure and blood pressure management. Usually, when measuring blood pressure, a cuff containing a fluid bag for compressing an artery is wound around the body surface of the living body, and the wrapped fluid bag is inflated and contracted to compress the artery, resulting in this. A change in arterial pressure pulse wave is detected to measure a blood pressure value.

  Here, the cuff means a band-like structure having a lumen, which can be wound around a measurement site of a living body, and by injecting a fluid such as gas or liquid into the lumen, It is used for measuring arterial pressure. 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, in a so-called upper arm type sphygmomanometer in which the upper arm is intended to be used as a site to be measured, the main body and the cuff are often separated from each other. Here, the cuff part is generally constituted by an air bag as a fluid bag for compressing the upper arm and a cover body as a bag-like exterior member containing the air bag.

  The upper arm type sphygmomanometer configured as described above has a problem that the storage property is not good when not in use, that is, the device becomes bulky when not in use. As literature which paid attention to such a problem, there is, for example, Japanese Utility Model Laid-Open No. 4-11005 (Patent Literature 1).

  The upper arm type sphygmomanometer disclosed in Patent Document 1 is configured such that a housing space in which the cuff portion is accommodated is provided in the main body portion, and the cuff portion is accommodated in the accommodation space when not in use. Here, in the upper arm type sphygmomanometer disclosed in Patent Document 1 described above, the waste space of the accommodation space provided in the main body is minimized by making the accommodation space into a substantially V-shaped longitudinal section. The sphygmomanometer is improved in storage when not in use.

  However, when the above configuration is adopted, it is necessary to provide a storage space that is large enough to store the cuff part in the main body, and it is possible to eliminate the useless space and make the storage space large. Even if it is made as small as possible, it cannot be said that downsizing of the sphygmomanometer has been sufficiently achieved. Particularly, in recent sphygmomanometers, in order to facilitate the attachment of the cuff portion to the upper arm by the subject's own hand, a curved elastic plate having a shape that fits the upper arm is accommodated in the cover body. In the sphygmomanometer configured in this way, it is difficult to accommodate the cuff portion by folding it small, so that the accommodation space is inevitably enlarged.

  Also, unlike the above configuration, an upper arm type sphygmomanometer is known in which an automatic winding mechanism for the upper arm is provided in a cuff configured separately from the main body. References disclosing such an upper arm type sphygmomanometer having an automatic winding mechanism include, for example, Japanese Patent Application Laid-Open No. 2005-230175 (Patent Document 2) and Japanese Patent Application Laid-Open No. 2005-237802 (Patent Document 3). Japanese Unexamined Patent Application Publication No. 2005-334125 (Patent Document 4) and the like. In the upper arm type sphygmomanometer equipped with an automatic winding mechanism, the cuff part is constituted by a machine frame formed in a substantially cylindrical shape and an air bag arranged on the inner peripheral surface of the machine frame, and the upper arm is formed by the cuff part. It will be inserted from the axial direction.

  Even the upper arm type blood pressure monitor configured as described above has a problem that the apparatus is large. This is because the cuff part needs to be formed in a size sufficient to enclose the upper arm in advance so that the upper arm can be inserted into the cuff part from the axial direction. This is because the outer shape of the entire apparatus is increased in size.

In Patent Document 4, the elbow rest for placing the arm elbow inserted into the cuff part at the time of measurement is in the hollow part for inserting the arm provided inside the cuff part when not in use. The structure which attached the elbow rest to the cuff part so that rotation was possible was disclosed.
Japanese Utility Model Publication No. 4-11005 JP 2005-230175 A JP 2005-237802 A JP 2005-334125 A

  Thus, in the upper arm type sphygmomanometer, there is a demand to make the device as small as possible from the viewpoint of improving the storage property when not in use, that is, saving space. However, as described above, in the conventional upper arm type sphygmomanometer, although various contrivances have been made, there has not yet been a sufficiently improved storage property.

  On the other hand, in an upper arm type sphygmomanometer intended to be used at home, the sphygmomanometer itself should be carried and placed on a mounting table such as a desk for blood pressure measurement. Therefore, the sphygmomanometer may be damaged when the user drops the sphygmomanometer when carrying it, or hits the sphygmomanometer against other articles. In particular, since the display unit and the operation unit are more fragile than other parts, there is a problem that when a strong impact is directly applied to the display unit and the operation unit, they are easily damaged. When the display unit or the operation unit is damaged, the sphygmomanometer itself cannot be used. Therefore, it is preferable to take some measures for preventing the display unit and the operation unit from being damaged.

  In sphygmomanometer 100A in the present embodiment, when cuff portion 150A is removed from main body portion 110A in a state where cuff portion 150A is attached to main body portion 110A, this is detected by micro switch 118 described above, and FIG. As shown, power is turned on to sphygmomanometer 100A (step S1). When the sphygmomanometer 100A is powered on and turned on, the sphygmomanometer 100A is initialized (step S2). Next, timing by the timer circuit 128 is started (step S3). Next, in step S4, it is determined whether or not a predetermined time has passed without operating the operation unit 121. If the operation is performed within the predetermined time (NO in step S4), the process proceeds to step S5. If the operation has not been performed within the predetermined time (YES in step S4), the process moves to step S12 to turn off the power.

  In step S5, it is determined whether or not cuff 150A is attached to main body 110A. If cuff 150A is not attached to main body 110A (NO in step S5), the process proceeds to step S6. If the cuff portion 150A is attached to the main body portion 110A (YES in step S5), the process moves to step S12 to turn off the power. The above-described micro switch 118 is used to determine whether the cuff portion 150A is attached to the main body portion 110A.

  In step S6, it is determined whether or not the measurement start button is turned on. If the measurement start button is turned on (YES in step S6), the process proceeds to step S7, and the measurement start button is turned on. If not (NO in step S6), the process returns to step S4.

  When measurement is possible, the CPU 122 starts driving the pump 133 and gradually increases the cuff pressure of the air bladder 170 (step S7). 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 133, and then gradually opens the closed valve 134 to open the air bag 170. The cuff pressure is gradually exhausted and the cuff pressure is gradually reduced (step S8), and the cuff pressure is detected in the process of depressurizing the cuff pressure at a low speed.

  Next, the CPU 122 calculates blood pressure values (maximum blood pressure value, minimum blood pressure value) by a known procedure (step S9). 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 S9, the calculated blood pressure value is displayed on the display unit 120 (step S10). Thereafter, the time count by the timer circuit 128 is reset (step S11), and the process returns to step S3.

  The measurement method described above is based on a so-called decompression measurement method that detects a pulse wave when the air bag is decompressed, but a so-called pressurization measurement method that detects a pulse wave when the air bag is pressurized is adopted. Of course it is also possible to do.

  In the sphygmomanometer 100A in the present embodiment described above, the accommodated portion 112 of the main body portion 110A is accommodated in the hollow portion 151 of the cuff portion 150A when the cuff portion 150A is attached to the main body portion 110A. Will be. Therefore, since the space that has been a dead space in the conventional sphygmomanometer can be used effectively, the sphygmomanometer can be significantly downsized in a non-use state. Therefore, it can be set as the upper arm type blood pressure meter excellent in storage property. Moreover, since the display part 120 and the operation part 121 which are weak parts are covered with the cuff part 150A in the non-use state, there is no fear that a large external force is applied to the display part 120 and the operation part 121, and the non-use state. It is possible to reliably prevent these parts from being damaged.

  Further, as described above, the cuff part 150A is attached to the main body part 110A by extrapolating the cuff part 150A to the accommodated part 112 of the main body part 110A from one direction. It can be a sphygmomanometer. Further, by providing a mechanism for fixing the cuff 150A to the main body 110A in a non-use state where the cuff 150A is attached to the main body 110A, the convenience in carrying the sphygmomanometer is improved.

  Furthermore, by detecting the attachment / detachment of the cuff 150A to the main body and controlling the power supply on / off based on this detection, it is not necessary to provide a separate power button, and the apparatus configuration is simplified and the power supply is simplified. Forgetting to turn off can be prevented.

  In blood pressure monitor 100A in the above-described embodiment, the case where a mechanism for fixing cuff portion 150A to main body portion 110A is provided in a non-use state in which cuff portion 150A is attached to main body portion 110A will be described as an example. However, it is also possible to adopt a configuration in which such a fixing mechanism is not provided. An example of such a configuration will be described as a first modification based on the present embodiment.

  FIG. 11 is a perspective view showing a state in which the cuff portion is removed from the main body portion in the first modification of the sphygmomanometer according to Embodiment 1 of the present invention. As shown in FIG. 11, in the sphygmomanometer 100B according to the first modification, the main body 110B and the cuff 150B are not provided with a locking mechanism for locking them. If comprised in this way, even if it grasps and lifts the handle provided in the cuff part when carrying a sphygmomanometer, the main-body part does not follow the cuff part, and it loses the convenience at the time of carrying. Therefore, in sphygmomanometer 100B according to the present embodiment, handle 119 is provided on the top surface portion, which is a portion to be exposed when main body portion 110B is not used. If comprised in this way, if the handle 119 is grasped and the main-body part 110B is lifted when carrying the sphygmomanometer 100B, the cuff part 150B will follow the main-body part 110B, and it is convenient for carrying around. Will contribute.

  Further, as described above, when the main body 110B and the cuff portion 150B are not provided with a locking mechanism for locking them, the cuff portion 150B is attached to the main body portion 110B when the cuff portion 150B is attached to the main body portion 110B. There is a risk of rotating with respect to the main body 110B around the axial direction. If excessive rotation occurs, the air tube 140 may be pulled and damaged. Therefore, in sphygmomanometer 100B according to the present embodiment, projection 167 is provided on the end surface in the axial direction of cuff 150B, and recess 117 that engages with projection 167 is provided on upper surface 111a of base 111 of main body 110B. ing. If comprised in this way, in the non-use state which attached the cuff part 150B to the main-body part 110B, it can prevent effectively that the cuff part 150B rotates with respect to the main-body part 110B centering on the axial direction.

  In blood pressure monitor 100A in the present embodiment described above, blood pressure measurement air system component 130 is provided in main body 110A, and air bag 170 and blood pressure measurement air system component 130 provided in cuff 150A are connected to an air tube. Although the case where it was set as the structure connected by 140 was illustrated, it is also possible to provide the air-system component for blood-pressure measurement in a cuff part. An example of such a configuration will be described as a second modification based on the present embodiment.

  FIG. 12 is a perspective view showing a state in which the cuff portion is removed from the main body portion in the second modification of the sphygmomanometer according to Embodiment 1 of the present invention, and FIG. 13 is a functional block diagram. As shown in FIGS. 12 and 13, in the sphygmomanometer 100 </ b> C in the second modified example, the main body part 110 </ b> C and the cuff part 150 </ b> C are not connected by the air tube 140. Instead, as shown in FIG. 13, the blood pressure measurement air system component 130, the CPU 122b, and the power supply unit 124b are provided in the cuff unit 150C. The main body 110C is also provided with a CPU 122a and a power supply 124a.

  The CPU 122a generates a measurement start command signal as a radio signal based on the user command received in the operation unit 121. The CPU 122b receives the radio signal generated by the CPU 122a, generates various control signals, and controls the expansion / contraction means 132 including the pump 133 and the valve 134. The pressure sensor 131 detects the pressure in the air bladder 170 and outputs a signal corresponding to the detected pressure to the oscillation circuit 125. The oscillation circuit 125 outputs a signal having an oscillation frequency corresponding to the output value of the pressure sensor 131 to the CPU 122b, and the CPU 122b converts this into a radio signal and transmits it to the CPU 122a.

  By configuring in this manner, the main body 110A and the cuff 150A can be completely separated, and it is not necessary to connect the main body 110A and the cuff 150A with an air tube. Therefore, the blood pressure monitor can be very easy to use.
