Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sphygmomanometer that is compact and optimal for home use.
[0002]
[Prior art]
Conventionally, when measuring blood pressure values in living bodies (arms / wrists) using the oscillometric method, cuffs have been used in order to stably measure the accuracy of thin and thick people. In order to make the band air bag volume constant, it is necessary to wrap the cuff band around the measurement site of the subject with a certain strength in advance.
[0003]
However, most of inexpensive sphygmomanometers for home use have a cuff band separation type in which the subject himself / herself needs to wrap the cuff band around the measurement site (see, for example, Patent Document 1). Therefore, measurement accuracy is likely to be affected depending on how the subject's cuff is wound.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0032]
FIG. 1 is a perspective view of the living body insertion block 2 of the sphygmomanometer 1A of the first embodiment.
[0033]
The sphygmomanometer 1A includes a living body insertion block 2 and a sphygmomanometer body 3 (see FIG. 7).
[0034]
The living body insertion block 2 is formed of a cylindrical rigid body into which the subject's (living body) arm, wrist, etc. 4 can be inserted as shown in a cross section in FIG. A mouth 2a is formed.
[0035]
The cuff strip 5 is held on the inner surface of the living body insertion block 2 so as to maintain a cylindrical shape, and both end portions 5a and 5b of the cuff strip 5 are connected to the outside in the same direction [see FIG. 5 (a), right side].
[0036]
The cuff belt 5 stores compression and measurement air bags, which are connected to pressurization means and exhaust means built in the sphygmomanometer body 3 to supply and discharge compressed air. Become so. The sphygmomanometer body 3 has a built-in control arithmetic circuit, which controls the supply / exhaust timing of the compressed air between the pressurizing means and the exhaust means, and is captured by a measurement air bag. The obtained pulse wave signal is converted into an electric signal by a pressure sensor, and this electric signal is processed into a blood pressure value or the like.
[0037]
The calculated blood pressure value and the like are displayed on the display means (see FIG. 15) 15 and stored in the storage means.
[0038]
Both end portions 5a and 5b of the cuff belt 5 drawn out of the living body insertion block 2 from the drawing port 2a are connected to the automatic winding mechanism 6. This automatic winding mechanism 6 is not limited to the one that rotates the winding cylindrical portion 7 with a motor as shown in FIG. 2 and simultaneously winds the cuff band 5 in the same direction. A mechanism that simultaneously pulls the parts in the same direction is also included.
[0039]
In the case of the sphygmomanometer 1A of the first embodiment, when the subject inserts the arm or the like 4 into the living body insertion block 2 and presses the power button 3c (see FIG. 11) of the sphygmomanometer body 3, automatic winding is first performed. Since the mechanism 6 is actuated so that both ends 5a and 5b of the cuff strip 5 are wound up at the same time (if the cylinder is pulled), the cuff strip is compared with the case where only one end 5a (or 5b) is wound up. 5 can be shortened and the winding diameter (stroke if a cylinder) can be reduced, so that the sphygmomanometer 1A can be made compact for home use.
[0040]
In this way, the cuff band 5 can be automatically wound around the measurement site with appropriate strength even for subjects having a thickness of 4 such as arms.
[0041]
Thereafter, the compressed air is supplied to and discharged from the air bag of the cuff belt 5 to perform the signal processing as described above, and the measured blood pressure value and the like are displayed.
[0042]
5 (a) shows a case where both ends 5a, 5b of the cuff belt 5 are simultaneously wound in the same direction, but both ends 5a, 5b of the cuff belt 5 are opposite as shown in FIG. 5 (b). It is also possible to draw out in the direction (left and right in FIG. 5B) and connect both ends 5a and 5b to the automatic winding mechanism 6 respectively and wind in the opposite direction at the same time. It is not always necessary to wind up at the same time, and it is possible to wind up with a time difference.
[0043]
FIG. 2 is a perspective view of the living body insertion block 2 of the sphygmomanometer 1B of the second embodiment.

[0045]
In the case of the sphygmomanometer 1B according to the second embodiment, both ends 5a and 5b of the cuff belt 5 are evenly wound by the rotation of the winding cylindrical part 7, and therefore only one end 5a (or 5b) is wound. Compared to the above, since the winding time of the cuff belt 5 can be halved and the winding diameter can be halved, the sphygmomanometer 1B can be made more compact for home use.
[0046]
FIG. 3 is a perspective view of the biological insertion block 2 of the sphygmomanometer 1C according to the third embodiment.
[0047]
A table 8 for the subject's arms 4 and the like is provided in the lower part of the living body insertion block 2 (see FIG. 5).

[0051]
Further, a locked portion 7 a that is locked to the lock portion 2 c at the initial winding position and the upper winding upper limit position is integrally formed on the outer surface of the winding cylindrical portion 7. Here, the winding initial position means that the winding cylindrical portion 7 rotates R to the right, and the locked portion 7a of the winding cylindrical portion 7 is locked against the right surface of the locking portion 2c. It is the state of FIG. Furthermore, the winding upper limit position is a state in which the winding cylindrical portion 7 is rotated to the left L, and the locked portion 7a of the winding cylindrical portion 7 is locked against the left surface of the lock portion 2c and locked (stopped). It is.
[0052]
In the sphygmomanometer 1D according to the third embodiment, the locked portion 7a is locked by the lock portion 2c at the winding upper limit position so that the upper limit position can be recognized and the position of the lock portion 2c is appropriately set. If it is set, it is possible to prevent the cuff belt 5 from being wound up at the minimum circumference that can be measured and to keep winding up more than necessary.
[0053]
Further, the locked portion 7a is locked by the lock portion 2c at the initial winding position, whereby the initial position can be recognized. Further, since the locking portion 2c and the locked portion 7a can be mechanically stopped, there is no need to provide a position sensor or the like.
