Description

  The present invention relates to a wrist sphygmomanometer that is convenient to carry and can measure blood pressure without rolling up an arm simply by winding a cuff band (compression band) around the wrist and operating the switch.

As conventional wrist blood pressure monitors, for example, those described in Patent Document 1 and Patent Document 2 are known.
FIG. 5 is a view showing an example of a conventional wrist blood pressure monitor, and FIG. 6 is a view showing a state in which the blood pressure monitor is worn on the wrist.

  This wrist type sphygmomanometer is obtained by integrally combining a sphygmomanometer main body 10 with a cuff band 20 wound around a wrist. A main mechanism for blood pressure measurement is built in a resin-made outer case 11 constituting the sphygmomanometer body 10, and an air bag (not shown) is built in the cuff band 20.

  When the switch 12 on the sphygmomanometer main body 10 is operated, this sphygmomanometer supplies air to the air bag, inflates the cuff band 20 and compresses the artery passing through the wrist, for example, a subsequent decompression process The necessary data is collected, blood pressure is calculated based on the collected data, and the calculated result is displayed on the display unit 13 on the upper surface of the sphygmomanometer body 10. Therefore, the measurement person can know the measurement result by visually observing the display.

  This wrist sphygmomanometer is measured by wrapping the cuff band 20 around the wrist, gently opening the hand with the palm up, and the wrist at the height of the heart, such as on the desk. In this case, it is important to first attach a blood pressure monitor appropriately to the wrist. In particular, as shown in FIG. 6, the position where the cuff belt 20 is wound around the wrist is important, and generally, with an interval H of about 1 to 2 cm from the base of the wrist (position with thick wrinkles) P, It is necessary to wrap the cuff belt 20.

  Such precautions are generally described in the instruction manual, but when you first started using it, pay attention as described in the instruction manual. In many cases, it is attached to an appropriate position. Also, for those who use without reading the instruction manual carefully, they often use it without noticing the contents of such precautions from the beginning, resulting in inaccurate measurements. It was.

  Therefore, in the sphygmomanometer shown in FIGS. 5 and 6, a seal-like gauge 16 for measuring the distance H is attached to the side surface of the exterior case 11 of the sphygmomanometer body 10, from the base P of the wrist to the mounting position. It is possible to ensure a proper distance.

  However, even though the gauge 16 is just a sticker-like one, there is a possibility of peeling or curling, and although attention is paid only at the beginning of use, attention is gradually stopped. As a result, there was a risk of inadequate wearing habits.

  In view of the above circumstances, an object of the present invention is to provide a wrist sphygmomanometer that can always prompt proper wearing on the wrist.

The wrist type sphygmomanometer according to the first aspect of the present invention includes a cuff band that is used by being wrapped around a wrist with a built-in air bag, and a sphygmomanometer body that is integrally coupled to the cuff band, and is wound around the wrist. Occasionally , a band piece is integrally provided on the side edge of the cuff band located on the fingertip side of the palm in a state of protruding toward the fingertip side, and the cuff band so that the tip edge of the band piece matches the base of the wrist. The cuff belt can be attached to the wrist at an appropriate position by wrapping the strap around the wrist .

  According to a second aspect of the present invention, in the first aspect, the strip is set such that the length along the circumferential direction of the wrist is shorter than the width of the wrist on the palm side and longer than the protruding dimension toward the fingertip side. It is characterized by that.

  The invention of claim 3 is characterized in that, in claim 2, a notation is given on the surface of the strip so as to instruct to wrap the cuff strip so that the strip faces the palm side.

  According to a fourth aspect of the present invention, in the second or third aspect, the center of the length along the circumferential direction of the wrist on the surface of the strip is instructed to align the center of the wrist with that position. It is characterized by.

  According to a fifth aspect of the present invention, in any one of the first to fourth aspects, the strip is formed integrally with a cloth or a resin constituting the cuff strip.

  The wrist type sphygmomanometer according to the invention of claim 1 is correct on the wrist by winding the cuff belt around the wrist in such a position that the strip is directed toward the palm side and the leading edge of the strip is aligned with the wrist root. Can be mounted in position. In this case, since the strip is provided integrally with the cuff strip which is the main part of the sphygmomanometer, it will not be forgotten to be assembled in the manufacturing process or peeled off while the user is using it. Users can always be impressed with the correct position. Moreover, since it is not attached later, there is no trouble of manufacturing and parts management.

  According to the invention of claim 2, since the strip is formed in a horizontally long shape (the length in the circumferential direction of the wrist is longer than the dimension in the protruding direction), it is difficult to sag during use and is separated from the base of the wrist. The dimensions can be measured reliably. Incidentally, if the strip is long and long in the protruding direction, it is likely to bend or bend at an arbitrary position in the protruding direction, and it may be difficult to accurately measure the distance. Moreover, since the dimension along the wrist circumference direction of the strip is set to be shorter than the width of the wrist, there is no hindrance when the wrist is moved.

  According to the invention of claim 3, since the notation for instructing to become the palm side is provided on the surface of the strip, the person who uses it for the first time can be urged to wear it in the correct direction.

  According to the invention of claim 4, the blood pressure monitor can be correctly worn by matching the notation provided at the center of the strip with the center of the wrist.

  According to the fifth aspect of the present invention, since the band piece is integrally formed on the cloth or resin constituting the cuff band, the formation can be simplified. In addition, the original gauge function can be exhibited without lingering over a long period of time.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 is a view showing a state in which the wrist sphygmomanometer is properly attached to the wrist, FIG. 2 is a perspective view of the sphygmomanometer, FIG. 3 is a sectional view taken along the line III-III in FIG. 2, and FIG. It is a top view of the cuff belt used with a sphygmomanometer.

  This sphygmomanometer is formed by integrally combining a sphygmomanometer main body 1 and a cuff belt 2 containing an air bag 2C (see FIG. 4) and wound around a wrist. The resin-made outer case 3 constituting the sphygmomanometer body 1 incorporates main mechanisms for measuring blood pressure (for example, a pressurizing mechanism, a depressurizing mechanism, and a control unit thereof), and the outer case 3 A liquid crystal display unit 4, a switch 5 and the like are provided on the upper surface. The contents to be displayed include the maximum blood pressure, the minimum blood pressure, and the pulse that are the measurement results.

  The cuff band 2 is to be wound at a position separated from the base P of the wrist by a predetermined distance H when the cuff band 2 is wound around the wrist, and at the side edge portion positioned on the fingertip side of the palm when wound around the wrist, A strip 8 protruding to the fingertip side by the same dimension as the distance H is integrally provided. For example, as shown in FIGS. 3 and 4, the cuff belt 2 has an air bag (inner bag) of a predetermined size on an inner peripheral portion of a resin core material 2 </ b> B (not shown in FIG. 4) called a cuff spring. 2C is fixed and accommodated and fixed in an outer bag 2A made of a cloth having a hard outer peripheral side and a soft cloth on the inner peripheral side. The strip 8 is an outer bag 2A made of cloth or a resin. It is integrally formed at the side edge of the core material 2B made of the above.

  The strip 8 is set such that the length S along the circumferential direction of the wrist is shorter than the width N of the wrist on the palm side and longer than the protruding dimension H toward the fingertip side. In addition, on the surface of the strip 8, a notation 8A (description of “palm side”) is given to instruct to wrap the cuff strip 2 so that the strip 8 faces the palm side. In addition, a notation 8B (scale-like line) is provided at the center of the surface of the strip 2 along the wrist circumference direction instructing to align the center of the wrist with that position.

Next, the operation will be described.
When using this wrist type sphygmomanometer, as shown in FIG. 1, the cuff belt is positioned at a position where the strip 8 faces the palm side and the leading edge of the strip 8 matches the base P of the wrist. Wrap 2 around your wrist. By doing so, a sphygmomanometer can be appropriately attached with a gap H between the wrist P and the base. In this state, the switch 5 on the sphygmomanometer body 1 is operated. Then, a series of blood pressure measurement operations are executed, and the result is displayed on the display unit 4. Therefore, the measurer can know the measurement result by visually checking the display.

  In the case of this sphygmomanometer, the strip 8 that indicates the mounting position is provided integrally with the cuff strip 2 that is a main part of the sphygmomanometer. Therefore, unlike pasting the gauge as a seal after the assembly process, it is not forgotten to be assembled in the manufacturing process or peeled off while the user is using it. Wearing can always impress the user. Moreover, since it is not attached later, there is no trouble of manufacturing and parts management. In particular, since the strip 8 is integrally formed with the cloth (outer bag 2A) or resin (core material 2B) constituting the cuff strip 2, it can be easily formed and does not extend over a long period of time. The original gauge function can be demonstrated. In addition, when the strip 8 is formed on the cloth, the strip 8 can be bent at the base when stored, so that it does not get in the way.

  Further, since the strip 8 is formed in a horizontally long shape (the length S in the circumferential direction of the wrist is longer than the dimension H in the protruding direction), the dimension H that is difficult to sag during use and is separated from the base P of the wrist is set. It can be measured reliably. Incidentally, if the strip 8 is long and long in the protruding direction, it is likely to bend or bend at an arbitrary position in the protruding direction, and it may be difficult to accurately measure the distance. In addition, since the dimension S along the wrist circumferential direction of the strip 8 is set to be shorter than the width N of the wrist, there is no hindrance when the wrist is moved.
