Description

The present invention relates to a massage technique evaluation device that can evaluate a massage technique of a practitioner.

When selling skin care products such as massage creams at stores, sales staff sometimes conduct demonstrations in order to make customers aware of the effects of the products. Salespeople understand demonstration procedures, hand movements, how to use skin care products, etc. by reading manuals and watching videos. On the other hand, sales staff learn how to apply force when applying skin care products by experiencing treatments performed by experts. Since the amount of force applied by an expert is intuitive and vague, it is difficult to accurately convey the technique to a salesperson in an easy-to-understand manner. Similarly, in the field of treatments such as beauty salons, it is not easy for practitioners to master the techniques of experts.

For this reason, a massage technique evaluation device has been proposed that evaluates a practitioner's technique by installing a pressure sensor inside a massaged member that simulates a predetermined part of the human body and measuring the pressure applied to the massaged member. (Patent Document 1).

Japanese Patent Application Publication No. 2008-83624

By the way, when massaging various parts of the human body, the amount of force applied differs depending on the part, so it is necessary to prepare massaged members that simulate various parts of the human body. Regarding this point, in the massage technique evaluation device described in Patent Document 1, the sensor is built into the massaged member that simulates a predetermined part of the human body, so various parts with built-in sensors must be prepared. However, since sensors are relatively expensive, there is a problem in that preparing sensors for various parts of the human body increases costs. Further, since the sensor is provided on the member to be massaged, when replacing the member to be massaged in another region, it is time consuming and inefficient to reconnect the sensor of the member to be massaged to the device. Furthermore, sensor maintenance and the like must be performed for each member to be massaged, resulting in a heavy management burden.

The present invention relates to a massage technique evaluation device in which a member to be massaged can be easily replaced and the cost of replacing the member to be massaged can be suppressed.

The present invention provides a massage technique evaluation device comprising a massaged member simulating a predetermined part of a human body and a sensor member having a sensor capable of measuring a load applied to the surface of the massaged member. The massage member provides a massage technique evaluation device that is detachably attached to the sensor member.

As described above, according to the massage technique evaluation device according to the present invention, it is possible to provide a massage technique evaluation device in which the massaged member can be easily replaced and the cost of replacing the massaged member can be suppressed.

Next, a massage technique evaluation device 1 according to an embodiment of the present invention will be described based on the drawings. As shown in FIGS. 1 to 3, the massage technique evaluation device 1 according to the present embodiment includes a massaged member 10 that simulates a predetermined part of the human body, and a sensor that can measure the load applied to the surface of the massaged member 10. The sensor member 20 has a sensor member 20, a data processing unit 30 that processes load data from the sensor member 20, an alarm generating unit 40 that generates an alarm, and a display unit 50 that displays an image of a graph showing temporal changes in the load data. . In this embodiment, the data processing section 30, the alarm generating section 40, and the display section 50 are installed in a personal computer 60, and the sensor member 20 is connected to this personal computer 60.

As shown in FIG. 1, the massaged member 10 includes a massaged member main body 12 that simulates a part of a human head, and a fixing plate 14 provided on the bottom surface of the massaged member main body 12.

The massaged member main body 12 imitates only about half of the facial side 12a of the head of a human body, and includes a bioskin 12a that constitutes the surface of the face and a bioskin 12a that is provided on the back of the head and supports the bioskin 12a. It includes a support plate 12b and a filling member 12c filled between the bioskin 12a and the support plate 12b. The bioskin 12a is made of synthetic resin such as urethane elastomer so that it feels similar to real skin. A plurality of screw holes 12d are formed in the support plate 12b for attachment to the fixing plate 14, and the filling member 12c is made of urethane foam or the like so as to obtain elasticity similar to that of the human face. .

The fixing plate 14 is made of a hard material such as hard resin or metal, and has a square shape. The fixing plate 14 has a surface side 14a having a sufficient area so that the entire area of the support plate 12b of the massaged member main body 12 comes into surface contact. A plurality of screw holes 14c are formed in the fixing plate 14 so as to align with the plurality of screw holes 12d formed in the support plate 12b of the massaged member main body 12, and the screws 15 are inserted through these screw holes. By screwing together, the massaged member main body 12 can be attached to the fixing plate 14. Further, a frame-shaped flange member (movement prevention member) 16 is installed on the bottom surface 14b side of the fixed plate 14 via screws 18 along the edge of the fixed plate 14 or near the inner side thereof. The inner edge 16a of the flange member 16 has approximately the same shape as the outer edge 26a of the sensor plate 26 so that the flange member 16 covers the sensor plate 26 of the sensor member 20, which will be described later. It is also slightly larger. In this embodiment, the flange member 16 is provided on the massaged member 10, but it may also be provided on the sensor member 20. In that case, the outer edge of the fixed plate 14 is formed to have approximately the same size as the inner edge of the flange. . With such a configuration, the member 10 to be massaged can be easily attached to and removed from the sensor member 20, and the member 10 to be massaged can be easily replaced with another part of the human body.

The sensor member 20 includes a so-called force plate 22 and a support base 24 that supports the force plate 22, as shown in FIGS. 1, 2, and 4. The force plate 22 includes a square sensor plate 26 and first to fourth sensors 28a to 28d provided near each of the four corners of the sensor plate 26. Each of the first to fourth sensors 28a to 28d is configured to be able to measure the load applied to the surface of the member to be massaged 10. In this example, four sensors were provided, but if only the load in the Z-axis direction (height direction) is to be measured, one sensor may be used. If the load in the plane direction is also measured, it is sufficient to provide at least three at different positions in the plane direction. As the sensors 28a to 28d, strain gauge type load cells, magnetostrictive type load cells, capacitance type load cells, etc. can be used.

In this embodiment, the member to be massaged 10 can be attached to the sensor member 20 by fitting the force plate 22 into the flange member 16 and placing it on the sensor member 20. At this time, since the inner edge 16a of the flange member 16 and the outer edge 26a of the sensor plate 26 of the force plate 22 are formed in almost the same shape, even if the practitioner presses the massaged member 10 and applies force in the plane direction, The massaged member 10 does not move relative to the sensor member 20, and the load in the plane direction can be accurately measured.

In the present embodiment, the massaged member 10 is modeled after a human face, but is not limited to this, and may be modeled after a human calf, décolletage, or the like. In this embodiment, since the member to be massaged 10 is configured separately from the sensor unit 20, the member to be massaged 10 can be obtained at low cost, and the cost of replacing it to various parts can be suppressed. Furthermore, by making the sensor section 20 separate in this way, even if the massaged member 10 is replaced with one for another part, there is no need to reconnect the sensor and its processing device. Easy to replace in various parts. .

When the personal computer 60 receives the load data from the first to fourth sensors 28a to 28d, the data processing unit 30 stores the load data in association with time, and also stores the load data in association with time, as well as horizontally translating time as shown in FIG. A graph with the load as the vertical axis is created, and the graph is displayed on the display unit 50.

The graph created by the data processing unit 30 can be based on changes in load applied in each of the X-axis direction, Y-axis direction, and Z-axis direction. Load changes in the X-axis direction and Y-axis direction can be determined from the positions and differences of the four sensors 28a to 28d, and load changes in the Z-axis direction can be determined, for example, from the average value of the four pressure sensors 28a to 28d. You can ask for it.

Specifically, as shown in FIG. 6(a), when a vertical downward force is applied to the load center point 29 indicating the center position of the load, the force in the Z-axis direction as shown in FIG. 6(b) A waveform graph is obtained. Here, the waveform graph has time on the horizontal axis and load on the vertical axis. Furthermore, as shown in FIG. 7(a), when force is applied downward and to the right from the load center point 29, waveform graphs in the Z-axis direction and the X-axis direction as shown in FIG. 7(b) are obtained. . Furthermore, as shown in FIG. 8(a), when force is applied downward and inward from the load center point 29, waveform graphs in the Z-axis direction and Y-axis direction as shown in FIG. 8(b) are obtained. . Furthermore, as shown in FIG. 9(a), when force is applied downward and diagonally to the right from the load center point 29, the Z-axis direction, the X-axis direction, and the Y-axis direction as shown in FIG. 9(b). A waveform graph of the direction is obtained.

When using the massage technique evaluation device 1 according to the present embodiment, first, it is necessary for an expert to perform a complete treatment and to store the expert's data. Next, when the practitioner receiving the procedure evaluation starts the treatment, the memorized data of the expert is displayed on the display section 50 for the entire displayable time as a dotted line, and the data of the practitioner is displayed in real time as a solid line. It is displayed on the display unit 50. In this way, since pre-recorded data and real-time data can be displayed simultaneously, the practitioner can recognize the difference in the amount of force applied by an expert from the display unit 50.

Furthermore, the massage technique evaluation device 1 according to the present embodiment is configured so that the alarm generation unit 40 issues an alarm when the peak value of the load change when graphed exceeds a threshold value. That is, as shown in FIG. 10, an upper limit 72a and a lower limit 72b of the load change are displayed on the display unit 50, and an alarm is issued when the peak of the load change exceeds the upper limit 72a or the lower limit 72b. As an alarm, for example, a speaker may be provided to emit an alarm sound, or an LED light may be provided to emit an alarm light. When the alarm is an alarm sound, the practitioner can recognize whether he or she is applying too much force without looking at the display unit 50.

Furthermore, the massage technique evaluation device 1 according to the present embodiment can be useful for drug development by, for example, evaluating the cases in which a preparation such as a massage cream is used and the case in which it is not used, and comparing the differences in degree of adjustment. Can be done.
