Description

[Detailed description of the invention] [Industrial applications]

 The present invention relates to a finger diameter measuring device for measuring a finger diameter.

[Prior art]

In a finger sphygmomanometer that measures blood pressure with a finger, blood pressure is measured by inserting a finger into a blood pressure measurement unit provided with a cuff band. Due to the small diameter, accurate measurements cannot be made unless the inner diameter of the cuff band is also matched to the finger diameter in mm. For this purpose, the diameter of the finger is measured in advance with a finger diameter measuring instrument, and thereafter, the finger is inserted into the blood pressure measurement unit of the finger blood pressure diameter so that the cuff band has an inner diameter that matches the measured value. Is being done. As a finger diameter measuring instrument for this purpose, JP-A-63-195
There is one disclosed in Japanese Patent Publication No. 812. This is one in which a plurality of measurement holes having different diameters are formed in a plate-shaped member, and the diameter of the finger can be determined by the diameter of the measurement hole having the minimum diameter into which a finger can be inserted.

[Problems to be solved by the invention]

However, in the above-mentioned type, because the diameter of the finger is measured by allowing the finger to pass through the measurement hole, a person with a large finger joint, a person with a large finger joint between the joints, and a finger There is a problem that it is difficult for a person or the like who is getting thicker as it goes to understand which diameter of the measurement hole should be his / her finger diameter. In addition, as shown in Japanese Utility Model Laid-Open No. 1-102801, a tape-shaped member with a scale is wound around a finger, and the scale is read at a position where one end of the tape-shaped member overlaps the other end of the tape-shaped member. Some measure the finger diameter by that, but it is difficult to perform the operation of winding the tape-like member around the finger with one end of the tape-like member pressed against a specific position of the finger, and it is difficult to perform the operation with the wound In addition to the one end and the scale not always being in a position that is easy to see,
Even if it is at a position where it is easy to see, it is hard to say that it is easy to read the finger diameter from the scale of the tape-shaped member wound around the small-diameter finger. The present invention has been made in view of such a point, and an object of the present invention is to provide a finger diameter measuring instrument capable of easily measuring a finger diameter.

[Means for Solving the Problems]

Thus, the present invention comprises a non-stretchable band that is wrapped around a finger with flexibility, and a flat base body having one end connected to one end of the band, and one end abutting the finger. On the surface of the base on which the other end of the band is wound and wound around the finger to form a loop, and on the other end of the band, a finger diameter display portion including an index and a scale is provided. The finger diameter display section for displaying the finger diameter based on the dimension from the one end of the base member to the portion in contact with the one end of the base member is provided a predetermined amount from the one end of the base member toward the other end, and the scale is set at this point. It is characterized by being provided offset by a fixed amount. [Operation] According to the present invention, the finger diameter is measured by wrapping the band around the finger and overlapping the other end of the band, and the inner diameter of the band wrapped around the finger is not fixed. The finger diameter can be accurately measured even with a finger having a large joint. Moreover, the band has one end connected to a flat base, and the other end of the band wound around a finger is superimposed on the surface of the base, and a finger diameter display is provided on the surface of the base and the other end of the band. The finger diameter is read from the part, the band can be easily wound around the finger by holding the base, and the finger diameter display part is provided offset from one end of the flat base body surface. In some cases, it is easy to read the finger diameter from the finger diameter display unit. [Embodiment] The present invention will be described below with reference to the illustrated embodiment. As shown in FIGS.
And a base 2 to which one end of the band 1 is connected. The band 1 here is made of a flexible non-stretchable material, one end of which is connected to the back side of one end of the base 2 by a fixing pin 13, and the other end has an index 14 and a knob 11. It has. The base 2 has a scale 20 indicating the finger diameter on the surface thereof. If the other end of the band 1 wrapped around the finger to be measured is superimposed on the surface of the base 2, the index 14 provided on the band 1
The finger diameter can be read by a finger diameter display unit including the scale 20 provided on the base 2. Here, one end of the band 1 wound around the finger is connected to one end of the flat base 2, and therefore, it is possible to hold the base 2 with one end of the band 1 around the finger. Therefore, the band 1 can be easily wound around the finger, and the scale 20 formed on the surface of the base 2 and the index 14 of the band 1 can be easily obtained.
Since the band 1 is located at a position offset from one end of the base 2 to which the band 1 is connected, the finger diameter indicated by the index 14 and the graduation 20 of the band 1 is set to be a flat base regardless of the finger diameter. 2 can be read on the surface, and it is very easy to read. 3 to 5 show another embodiment. Here, the base 2
Is formed by a substrate 21 and a display plate 22 superposed on the substrate 21, and the other end of the band 1, one end of which is connected to one end of the base 2 by a female fixing pin 13, is connected to the substrate 21. It is slidably disposed in the gap between the display plate 22 and the knob 11 having the index 14 facing the opening provided in the display plate 22, and has a loop shape of the band 1. A finger is inserted in a state where the inside diameter of the band is increased, and then the other end of the band 1 is slid along the surface of the base 2 by grasping the knob 11, thereby reducing the inside diameter of the loop portion of the band 1. When the band 1 is wound around the finger, the accurate diameter of the finger can be measured from the index 14 and the scale 20.
In this case, since the band 1 is in a loop shape in advance,
The measurement operation is easier than that of the embodiment.
The width of the opening of the display plate 22 is smaller than the width of the band 1. In addition, since the thickness of the knob 11 is increased, the band 1
Does not fall out of the base 2. In addition, as shown in FIG. 4 (b), a tongue piece 16 is provided at one end of the band 1 so as to protrude inside the loop-shaped portion. By adopting a material having elasticity and elasticity, the loop-shaped portion is always circular. The tongue 16 also prevents the skin of the finger from being pinched between the band 1 and the base 2. A spring member is arranged between the knob portion 11 and the base 2 so that the knob portion 11 is urged leftward in FIG. 4, that is, the loop portion of the band 1 keeps the maximum diameter. You may keep it. FIG. 6 shows the finger sphygmomanometer 3. The main body 31 of the finger sphygmomanometer has a penetrating circular opening 30 for measurement having a circular cross section through which a finger can be inserted, and a cuff band 32 is provided in the measurement opening 30. It is formed as something. An operator 33 is slidably disposed on one end surface of the main body 31, and the inner diameter of the cuff band 32 is changed by sliding the operator 33 to which one end of the cuff band 32 is connected. You can do it. Further, the main body 31 provided with the blood pressure value display section 38 and the switch section 39 on one side is slidable in the longitudinal direction covering the three faces of the main body 31 and is slidable in one direction. A slide cover 36 that closes both ends is attached. An operation element 33 disposed on one end surface of the main body 31 to which the gauge 37 is attached is disposed in the measurement opening 30 of the main body 31 and has a loop-like shape in which one end side is connected to the main body 31. The other end of the cuff band 32 is connected to the opening 30 for measurement.
If you slide the operator 33 with your finger
The cuff band 32 changes the inner diameter of the ring-shaped portion, and therefore, by simply sliding the operation element 33, the cuff band 32 is securely inserted into the finger inserted into the measurement opening 30. Can be wound. Note that the sliding operation of the operation element 33 in the direction of increasing the inner diameter of the cuff band 32 is locked so that the cuff band 32 is not accidentally loosened. And lock handle
The cuff band 32 can be loosened by operating the button 34 to release the lock and then sliding the operation element 33. The finger diameter is measured by the finger diameter measuring instrument described above, and then, when the cuff band 32 is tightened by operating the manipulator 33 through the finger through the measurement opening 30 of the finger sphygmomanometer, the manipulator 33 indicated by the gauge 37 is If the position is the same as the measured value,
