1. Field of the Invention
The present invention relates to a biometric data-measuring instrument and a biometric data-measuring system that measure biometric data such as the tenderness and hardness of a muscle tissue of a living organism, a muscle strength meter, and a muscle strength-measuring system.
Priority is claimed on Japanese Patent Application No. 2009-280666, filed on Dec. 10, 2009, the contents of which are incorporated herein by reference.
2. Background Art
A muscle hardness meter including a detector having a probe which contacts a living organism, and a device main body that performs various computations and displays muscle hardness is known in the related art (e.g. refer to Japanese Patent Application, First Publication No. 2008-272286.
In the related art there is a muscle strength meter including an attachment that includes a contacting part that contacts to the living organism and an attaching shaft part provided on the contacting part, a detector that includes an insertion hole for inserting the attaching shaft part therein and a pressure sensor built into a tip of the insertion hole, and a device main body that performs various types of computations to an input signal from the detector. Using this type of muscle strength meter, in a state where the attaching shaft part is inserted in the insertion hole, the contacting part is made to contact the living organism; when the contacting part is pressed using muscle strength, the sensor is also pressed via the attaching shaft part, and the device main body performs various types of computations to this detection result to display the muscle strength. A muscle strength meter of a different type to this one is disclosed in, for example, Japanese Patent Application, First Publication No. 2004-180982.
However, the biometric data-measuring instrument and the muscle strength meter described above include, in addition to a detector having a probe and an attachment that contacts to the living organism, a device main body for displaying the measurement result. The whole devices of the biometric data-measuring instrument and the muscle strength meter described above are consequently bulky, making them inconvenient for carrying.
The present invention has been realized after consideration of these problems, and aims to provide a biometric data-measuring instrument and a biometric data-measuring system, a muscle strength meter, and a muscle strength-measuring system with excellent portability.
To achieve the above problems and achieve the objects, the present invention employs the following means.
A biometric data-measuring instrument according to the invention measures data relating to a living organism by applying pressure to the living organism. The biometric data-measuring instrument includes: a casing, an auxiliary contacting part that extends from the casing, the auxiliary contacting part being contacted against a vicinity of a point to be measured on the living organism and applying pressure to the vicinity of the point to be measured, a main contacting part that, in a state where the auxiliary contacting part is applying pressure to the vicinity of the point to be measured, is contacted against the point to be measured and applies pressure to the point to be measured in the direction in which the auxiliary contacting part is applying pressure to the vicinity of the point to be measured, a pressure sensor that is provided inside the casing and measures a pressure that the main contacting part receives from the point to be measured, a biometric data display unit that is provided on the casing and displays the measured biometric data. A tip of the auxiliary contacting part extends outward from a base side thereof.
According to this configuration, since the casing includes the biometric data display unit for displaying measured biometric data (e.g. tissue hardness), there is no need to provide a separate device including the biometric data display unit. The configuration of the whole biometric data-measuring instrument can thus be made compact. Therefore, the portability of the biometric data-measuring instrument can be enhanced.
Furthermore, since the tip of the auxiliary contacting cylinder part extends further outward than the base side, the auxiliary contacting part is easily contacted against a point to be measured. Since this makes it possible to considerably adjust the relative angle of the living organism and the biometric data-measuring instrument even if the point to be measured cannot easily be visually confirmed with biometric data display unit, a reduction in visibility from the biometric data display unit can be suppressed.
The biometric data display unit can be facing in the pressure-receiving direction in which the auxiliary contacting part receives pressure from the living organism.
According to this configuration, since the biometric data display unit is facing in the pressure-receiving direction, when the person who is measuring is positioned in the pressure-receiving direction with respect to the point to be measured, he can easily visually confirm the biometric data.
The casing can have a grasp part extending in a direction intersecting the pressure-applying direction, with the biometric data display unit facing in an opposite direction to a direction in which the grasp part extends.
According to this configuration, since the casing has a grasp part extending in a direction intersecting the pressure-applying direction, the orientation of the casing can be stabilized by grasping the grasp part such that it is in a vertical plane. This makes it possible to apply pressure stably to the point to be measured, and to more accurately measure the biometric data.
Furthermore, since the biometric data display unit is facing in the opposite direction to the direction in which the grasp part extends, when the biometric data display unit is below the eye level of the person who is measuring, he can easily visually confirm the muscle hardness and tenderness.
The auxiliary contacting part can include a detachable extending part that is detachably provided at a tip of the auxiliary contacting part, and a locking mechanism at a tip of this detachable extending part.
According to this configuration, since the auxiliary contacting part includes the detachable extending part that is detachably provided at the tip, and the locking mechanism, the portability of the biometric data-measuring instrument can be further enhanced.
Furthermore, the biometric data-measuring instrument can include a securing mechanism that secures the auxiliary contacting part such that the tip of the main contacting part is positioned further to the pressure-applying direction side than the tip of the auxiliary contacting part, and a switch that, when switched on, makes the biometric data display unit display the measured biometric data.
According to this configuration, since the instrument includes the securing mechanism that secures the auxiliary contacting part in the pressure-applying direction, and the switch, it can measure, for example, biometric data such as tenderness (pain threshold). This enables the biometric data-measuring instrument to function as a pressure algometer.
A biometric data-measuring system according to the present invention can include one of the biometric data-measuring instruments described above including a radio communication unit, and a printer that performs a radio communication with the radio communication unit to print the measured biometric data.
According to this configuration, since the printer performs a radio communication with the radio communication unit to print the measured biometric data, the measured biometric data can be reliably recorded. Therefore, even when the biometric data display unit is difficult to confirm visually, the measured biometric data can be reliably ascertained.
A muscle strength meter of the present invention includes an attachment that contacts against a living organism, and a muscle strength meter main body that is attached to the attachment, detects pressure from the living organism via the attachment, and measures the muscle strength of the living organism. The attachment includes an contacting seat part with an extending contacting face that contacts against the living organism, and an attaching shaft part for attaching the attachment to the muscle strength meter main body. The muscle strength meter main body also includes an insertion hole that the attaching shaft part is inserted into, a pressure sensor provided at a tip of the insertion hole, and a muscle strength display unit that displays the measured muscle strength. That is, it is possible to adjust the relative angle between the attachment and the muscle strength meter main body when seen from the axis direction of the attaching shaft part.
According to this configuration, since the attachment is attached to the muscle strength meter main body and includes the muscle strength display unit for displaying muscle strength, there is no need to provide a separate device including the muscle strength display unit. The whole configuration of the muscle strength meter can thus be made compact. Therefore, the portability of the muscle strength meter can be enhanced.
Moreover, since it is possible to adjust the relative angle between the attachment and the muscle strength meter main body when viewed from the long direction of the muscle strength display unit, it is easier to make the contacting seat part contact the living organism. Therefore, even when the point to be measured is one that is difficult to confirm visually with the muscle strength display unit, since considerable adjustment can be made to the relative angle between the living organism and the muscle strength meter main body, reduction of visibility can be suppressed.
A hexagonal positioning part can be provided on the attaching shaft part, with the cross-sectional shape of the insertion hole also being hexagonal.
According to this configuration, since the hexagonal positioning part is provided on the attaching shaft part, and the cross-sectional shape of the insertion hole is hexagonal, the attachment can be easily positioned to a rotation position around the axis of the insertion hole. Furthermore, since the attachment can be prevented from moving when it receives pressure from the living organism, the biometric data can be measured more precisely.
A top face of the muscle strength meter main body with its back to a face where the insertion hole is formed can be dome-shaped, and a plurality of protrusions for belt for passing a belt through can be formed on the top face. The tips of the protrusions for belt and a vertex of the rear-face dome-shape are set at the same height.
According to this configuration, by passing a belt through the protrusions for belt, the muscle strength meter main body is made easier to grasp. Furthermore, since the tips of the protrusions for belt and the vertex part of the top face of the muscle strength meter main body are set at the same height, when the top-face side is placed on a flat surface, the protrusions for belt and the vertex part can stably support the pressure from the living organism.
A muscle strength measuring system according to the present invention includes: one of the muscle strength meters described above including a radio communication unit, and a printer that performs a radio communication with the radio communication unit to print a measured muscle strength of the living organism.
According to this configuration, since the printer performs a radio communication to print the measured muscle strength, the measured muscle strength can be reliably recorded. Even if the muscle strength display unit is difficult to confirm visually, the muscle strength can be reliably ascertained.
According to the present invention, the portability of the biometric data-measuring instrument can be enhanced.
Embodiments of the invention will be explained with reference to the drawings. The embodiments are intended to be illustrative in order to further understanding of the main points of the invention, and unless stated otherwise are not intended to restrict the invention only to these embodiments.

The first flange part 33 and the second flange part 32 have the same diameter, and both are larger than the inner diameter of the tip flange 27. That is, when the second flange part 32 is contacting against the tip flange 27, the auxiliary cylinder part 26 can be prevented from being dislocated from the supporting cylinder part 16.

The manipulation part 8 includes manipulation buttons and the like for performing various types of manipulations, and, as shown in
The control part 9 performs the following processes in accordance with muscle hardness measurement mode and muscle measurement mode. When muscle hardness measurement mode is set, the control part 9 reads measurement signals outputted from the second pressure sensor 53 and the first pressure sensor 54, and successively displays their respective measurement value information in the biometric data display unit 6. The control part 9 then reads threshold information stored in a memory 9a, and compares the threshold information with the measurement value information of the first pressure sensor 54. If the control part 9 judges that the measurement value information of the first pressure sensor 54 has exceeded the threshold information, it stores the measurement value information of the second pressure sensor 53 at that time in the memory 9a. The memory 9a also reads the measurement signal outputted in accordance with the pressing force against the second pressure sensor 53, and successively displays its measurement value information in the biometric data display unit 6. The control part 9 then reads a response signal outputted from a switch 10, and stores measurement value information at the time of reading the response signal in the memory 9a. In each of the measurement modes, the control part 9 makes the radio communication unit 85 output a radio signal indicating the measurement value information stored in the memory 9a.
The switch 10 can switch on and off, and is connected to the control part 9 via a cable (not shown). When in a released natural state, the switch 10 is off and does not output a response signal. When the person who is measuring presses the switch 10, it switches on and outputs a response signal.
The radio communication unit 85 complies with, for example, the Bluetooth specification. Based on a signal inputted from the control part 9, the radio communication unit 85 outputs a radio signal indicating the same measurement value information as that stored in the memory 9a.
As shown in
Subsequently, a method of using the biometric data-measuring instrument M and the biometric data-measuring system 51 described above will be explained.
Firstly, when using the biometric data-measuring instrument M as a muscle hardness meter, as shown in
The pressing force against the tip chip 40 is applied directly to the main needle part 37. That is, the pressing force against the tip chip 40 is applied to the core 46. The core 46 consequently moved rearward with respect to the outer shell 45, and a pressing force is applied to the second pressure sensor 53. At this time, the second pressure sensor 53 outputs a measurement signal in accordance with the pressing force. The pressing force against the second pressure sensor 53 is also applied to the outer shell 45.
In addition, the pressing force against the auxiliary cylinder part 26 is indirectly applied via the coil spring 43 to the main needle part 37. Consequently, the main needle part 37 moves rearward with respect to the supporting tube part 16, and a pressing force is applied to the first pressure sensor 54. The first pressure sensor 54 outputs a measurement signal in accordance with the pressing force at that time.
The control part 9 reads the measurement signals outputted from the second pressure sensor 53 and the first pressure sensor 54, and successively displays their respective measurement value information on the biometric data display unit 6. At this time, since the biometric data display unit 6 faces in an opposite direction to the pressure-receiving direction and the direction in which the grasp part 3 extends, it is easy for the person who is measuring to visually confirm the hardness of the muscle displayed on the biometric data display unit 6.
The control part 9 then reads the threshold information stored in the memory 9a, and compares it with the measurement value information of the first pressure sensor 54. When the control part 9 judges that the measurement value information of the first pressure sensor 54 has exceeded the threshold information, it stores the measurement value information of the second pressure sensor 53 at that time in the memory 9a. Thus the muscle hardness is measured and stored.
The control part 9 makes the radio communication unit 85 output a radio signal indicating the measurement value information when it judged that the measurement value information had exceeded the threshold information. The printer P that receives this radio signal prints the muscle hardness indicated by the radio signal on heat-sensitive paper.
On the other hand, when using the biometric data-measuring instrument M as a tenderness meter, as shown in
The pressing force against the tip chip 40 is applied directly to the core 46. Consequently, the core 46 moves rearward with respect to the outer shell 45, and a pressing force is applied to the second pressure sensor 53. At this time, the second pressure sensor 53 outputs a measurement signal in accordance with this pressing force. The control part 9 reads the measurement signal, and successively displays the measurement value information on the biometric data display unit 6. At the moment when the person being measured feels pain, he presses the switch 10, making the switch 10 output a response signal. The control part 9 reads this response signal, and displays response information on the biometric data display unit 6. The response information is displayed in a textual or diagrammatic format. In addition, the control part 9 stores the measurement value information at the time of reading the response signal in the memory 9a. Thus the tenderness is measured and stored.
The control part 9 makes the radio communication unit 85 output a radio signal indicating the measurement value information at the time of reading the response signal. The printer P receives this radio signal, and prints the tenderness indicated by the radio signal on heat-sensitive paper.
To cancel the lock of the auxiliary cylinder part 26, the auxiliary cylinder part 26 is pushed to the rear side, the protrusions 22 are moved from the recesses for engagement 36, and the auxiliary cylinder part 26 is rotated around the axis L. When the protrusions 22 match the second recesses 32a, the auxiliary cylinder part 26 is released. The urging force of the coil spring 43 then pushes the auxiliary cylinder part 26 forward, and the protrusions 22 pass the second recesses 32a, holding the auxiliary cylinder part 26 in the normal position E1.
In using the biometric data-measuring instrument M as a muscle hardness meter, if the biometric data display unit 6 is placed at a point which is not easily visible to the person who is measuring, visibility can be adjusted in the following manner.
Firstly, the detachable extending part 80 is attached to the auxiliary cylinder part 26. The detachable extending part 80 is thereby arranged concentrically with the auxiliary cylinder part 26, and the surface of the detachable extending part 80 is arranged in a common plane with the tip face 26a of the auxiliary cylinder part 26. In this state, if the detachable extending part 80 is contacted against the living organism and then pushed, the increase in the contact area with the living organism makes it easier to contact against the point to be measured. That is, as shown in
When the auxiliary cylinder part 26 is attached to the detachable extending part 80, the contact area with the living organism increases, thereby dispersing the load on the living organism. Consequently, even if the point to be measured is comparatively soft, the soft part of the living organism can be detected precisely, without intrusion of the auxiliary cylinder part 26. On the other hand, if the point to be measure is hard, it can be measured precisely by removing the detachable extending part 80 and contacting the auxiliary cylinder part 26 against it.
In attaching the detachable extending part 80 to the auxiliary cylinder part 26, the rotation position of the detachable extending part 80 with respect to the tip cap 70 is adjusted such that the securing protrusions 82 of the detachable extending part 80 match the peripheral wall recesses 74a of the tip cap 70. In that state, the tip cap 70 is arranged in the through hole 80a of the detachable extending part 80. As shown in
In a state where the securing protrusions 71 of the tip cap 70 are contacting against the bottoms 84a of the notches 84, as shown in
At this time, the axis L direction end of the tip cap 70 contacts against the axis L direction front side of the securing protrusion 82. The detachable extending part 80 is thereby restricted from moving forward in the axis L direction. As shown in
As described above, according to the biometric data-measuring instrument M, since the casing 1 includes the biometric data display unit 6 that displays measured muscle hardness and tenderness, there is no need to provide a separate device including the biometric data display unit 6. The configuration of the whole biometric data-measuring instrument M can thus be made compact. Therefore, the portability of the biometric data-measuring instrument M can be enhanced. Moreover, since the tip of the auxiliary cylinder part 26 extends further outward than the base side, the auxiliary cylinder part 26 is easily contacted against a point to be measured. Since this makes it possible to considerably adjust the relative angle of the living organism and the biometric data-measuring instrument M even if the point to be measured cannot easily be visually confirmed with biometric data display unit 6, a reduction in visibility from the biometric data display unit 6 can be suppressed.
Furthermore, since the biometric data display unit 6 is facing the pressure-receiving direction, when the person who is measuring is positioned in the pressure-receiving direction with respect to the point to be measured, he can easily visually confirm the muscle hardness and tenderness. Moreover, since the biometric data display unit 6 is facing in the opposite direction to the direction in which the grasp part 3 extends, when the biometric data display unit 6 is below the eye level of the person who is measuring, he can easily visually confirm the muscle hardness and tenderness.
Furthermore, since the casing 1 includes the grasp part 3 extending in a direction that intersects the pressure-applying direction, the orientation of the casing 1 can be stabilized by grasping the grasp part 3 such that it is in a vertical plane. This makes it possible to apply pressure stably to the point to be measured, and to more accurately measure the muscle hardness and tenderness.
Furthermore, since the detachable extending part 80 is detachably provided to the tip cap 70, the portability of the biometric data-measuring instrument M can be further enhanced. Also, the biometric data-measuring instrument M is easier to handle, enables biometric data to be measured speedily and precisely.
By rotating the detachable extending part 80 and the tip cap 70 relative to each other to make the protrusion 83 engage with the long groove 73, the securing protrusions 71 and the bottoms 84a of the notches 84 are contacted against each other; the securing protrusion 82 and the axis L direction end of the tip cap 70 are also contacted against each other. Consequently, the detachable extending part 80 and the tip cap 70 can be locked and unlocked speedily and reliably. Also, due to the notches 84, the securing protrusions 71 can be reliably contacted, and it is possible to speedily and easily lock the detachable extending part 80 and the tip cap 70. Since the bottoms 84a of the notches 84 are inclining, the securing protrusions 71 can be guided, and the detachable extending part 80 and the tip cap 70 can be reliably locked such that they do not rattle. Due to the provision of the peripheral wall recess 74a and the securing protrusion 82, the detachable extending part 80 and the tip cap 70 can easily be arranged in their appropriate rotation positions.
Due to the provision of the first flange part 33, the second flange part 32, and the protrusions 22, the auxiliary cylinder part 26 can be reliably locked with a simple configuration. Also, due to the provision of the recesses for engagement 36, the locked state can be reliably maintained.
Furthermore, since the detachable extending part 80 is mode of transparent resin, the point to be measured can be viewed through it. This enables the tip chip 40 to be contacted easily and reliably against the point to be measured.
Furthermore, since the biometric data-measuring instrument M includes a securing mechanism that secures the auxiliary cylinder part 26 on the press-applying direction side, and the switch 10, it can be made to function both as a pressure algometer and a muscle hardness meter. That is, since the auxiliary cylinder part 26 can be locked in the rearward position E2, muscle hardness and tenderness can be easily measured precisely using a single device. Further, since it can function both as a muscle hardness meter and a pressure algometer, the management load can be reduced.
Moreover, the switch 10 enables the person being measured to notify the person who is measuring the moment he feels pain. This makes it possible to precisely measure the tenderness of the person being measured. Since the measurement value information is stored according to the response signal of the switch 10, measuring can be performed precisely and easily. If the person being measured indicates the moment that he feels pain by verbal communication, a time gap arises between the moment he feels pain and the moment that he speaks, making it difficult to measure precisely. If he indicates the moment that he feels pain by movement, a time gap arises between the moment the person who is measuring sees that movement and the moment that he looks at the display on the biometric data display unit 6, making it difficult to measure precisely. That is, according to the biometric data-measuring instrument M of this embodiment, the person being measured need only press the switch 10 to easily notify the timing, whereby measuring can be performed precisely.
Furthermore, since the printer P performs a radio communication to print the measured muscle hardness and tenderness, the measured muscle hardness and tenderness can be reliably recorded. Even when the biometric data display unit 6 is difficult to confirm visually, the muscle hardness and tenderness can be reliably ascertained.
Moreover, since the tip of the auxiliary cylinder part 26 extends outwards from the base side, when measuring a hard point on the living organism, the hardness of the muscle of the living organism can be measured by contacting the auxiliary cylinder part 26 against that point. When the detachable extending part 80 is attached, the hardness of a soft point on the living organism can be measured accurately. Therefore, irrespective of the hardness of the point to be measured, the biometric data-measuring instrument of the above-described embodiment can measure the hardness of that point easily and precisely.
While in the above-described embodiment, one type of detachable extending part 80 is used, this is not limited. For example, a number of differently-sized types of detachable extending parts can be prepared beforehand, and tip caps of those sizes can be exchanged selectively. ‘Size’ includes not only dimensions but also shapes. As for example shown in
While the above-described embodiment includes the switch 10, this need not be included. It is preferable to include the switch 10, however, as this can achieve a precise measurement.
While in the above-described embodiment, the response from the switch 10 is notified using the biometric data display unit 6, this configuration is not limited and can be modified where necessary. For example, the response can be notified using sound, vibrations, etc.
While in the above-described embodiment, the printer P uses heat-sensitive paper as the printing medium for printing the measured biometric data, ordinary paper or another film-like printing medium can be used.
While in the above-described embodiment, the radio communication units 85 and 90 employ the Bluetooth specification as a radio method, they can employ another specification or an independent communication method.
As shown in
The contacting seat part 125 is made of resin, a lower bottom part and an upper bottom part of the trapezoidal shape being substantially elliptical in plan view (see
The elliptical plate 127 is a metal plate formed in a substantially elliptical shape in plan view, and extends in the same direction as the upper bottom part. An attaching shaft part 126 is welded to a rear face of the elliptical plate 127, and extends in a direction that intersects the direction in which the elliptical plate 127 extends. A projection-side tapered part 126a having a diameter that gradually decreases as it approaches the tip is formed at a tip part of the attaching shaft part 126. That is, the tip part of the attaching shaft part 126 is tapered.
As shown in
Moreover, the elliptical plate 127 is provided inside the contacting seat part 125. A connection part welded to the rear face of the elliptical plate 127 is also arranged inside the contacting seat part 125.
Returning to
As shown in
An insertion hole 111 is formed in the column part 133, and extends in the axis T direction. The insertion hole 111 is open from the tip face of the column part 133. Also, the insertion hole 111 is concentric to the column part 133. Moreover, the cross-sectional face of the insertion hole 111 is formed in a hexagonal shape. Therefore, when the attaching shaft part 126 is inserted into the insertion hole 111, the positioning part 128 fits into the insertion hole 111, thereby positioning the attachment 102 and the muscle strength meter main body 103 in their relative rotation positions, and restricting their relative rotation. The hexagonal shape of the outer periphery of the column part 133 and the cross-sectional hexagonal shape of the insertion hole 111 are oriented in the same rotation position around the axis T of the insertion hole 111, and the external appearance of the column part 133 makes it easy to see the orientation of the insertion hole 111.
As shown in
Moreover, as shown in
The pressure sensor 110 is built into the tip of the insertion hole 111. When the attaching shaft part 126 is inserted in the insertion hole 111, the pressure sensor 110 receives the pressure from the attachment 102, detects this pressure, and outputs the detection result to the control part 121 (see
As shown in
As shown in
As shown in
The radio communication unit 150 complies with, for example, the Bluetooth specification, and, as shown in
Subsequently, a method of using the muscle strength meter N and the muscle strength-measuring system S2 in the embodiment described above will be explained.
Firstly, the attaching shaft part 126 is inserted in the insertion hole 111, and the attachment 102 is attached to the muscle strength meter main body 103 (see
The attachment 102 is then released from the muscle strength meter main body 103, rotated, and reattached, while adjusting the relative angle between the attachment 102 and the muscle strength meter main body 103. Thus, even when the muscle strength display unit 106 of the muscle strength meter N is at a position that is difficult to confirm visually, the muscle strength display unit 106 can be moved to a position where it can easily be seen (see
In attaching the attachment 102 to the muscle strength meter main body 103, when the attaching shaft part 126 is inserted in the insertion hole 111 as far as a predetermined position, the attachment 102 is then secured to the attachment 102 in the following manner. As shown in
When the attaching shaft part 126 is inserted in the insertion hole 111, due to the ring part 142 provided on the inner peripheral face of the insertion hole 111, the attaching shaft part 126 enters without contact between its metal and the metal of the inner peripheral face of the insertion hole 111, the only contact being the metal-against-resin contact between the attaching shaft part 126 and the ring part 142. Moreover, since a plurality of ring parts 142 are provided, the attaching shaft part 126 is supported at a plurality of points, and can therefore be inserted stably.
As described above, according to the muscle strength meter N, since the attachment 102 is attached to the muscle strength meter main body 103, which includes the muscle strength display unit 106 for displaying the muscle strength, there is no need to provide a separate device including the muscle strength display unit 106. The whole configuration of the muscle strength meter N can thus be made compact. Therefore, the portability of the muscle strength meter N can be enhanced. Moreover, since it is possible to adjust the relative angle between the attachment 102 and the muscle strength meter main body 103 when viewed from the long direction of the muscle strength display unit 106, it is easier to make the contacting seat part 125 contact the living organism. Therefore, even when the point to be measured is one that is difficult to confirm visually with the muscle strength display unit 106, since considerable adjustment can be made to the relative angle between the living organism and the muscle strength meter main body 103, reduction of visibility can be suppressed.
Furthermore, since the attaching shaft part 126 includes the polygonal positioning part 128, and the cross-sectional shape of the insertion hole 111 is hexagonal, the attachment 102 can easily be positioned at a rotation position around the axis of the insertion hole 111. Moreover, the attachment 102 can be prevented from moving when it receives pressure from the living organism, thereby enabling the biometric data to be measured more precisely.
By passing a belt through the leg part 115, the muscle strength meter main body 103 is made easier to grasp. Furthermore, since the tips of the leg parts 15 and the vertex part 113a are the same height, when the top-face side is placed on a flat surface, the legs 115 and the vertex part 113a can stably support the pressure from the living organism.
Furthermore, since the printer P performs a radio communication to print the measured muscle strength, the measured muscle strength can be reliably recorded. Even when the muscle strength display unit 106 is difficult to confirm visually, the muscle strength can be reliably ascertained.
Furthermore, since the column part 133 is formed in a hexagonal shape, and the orientation of insertion hole 111 is the same as that of the column part 133, when the supporting part 131 is secured in the muscle strength meter main body 103, it is easy to visually confirm the orientation of the insertion hole 111 while looking at the external appearance of the column part 133. As a result, the burden of assembling work can be reduced.
Furthermore, since the ring parts 142 are provided on the inner peripheral face of the insertion hole 111, the attaching shaft part 126 contacts the ring parts 142 when it is inserted into the insertion hole 111, making insertion easier.
