DETAILED DESCRIPTION OF THE INVENTION

[0024] The present invention will be described below through embodiments of the invention, but the following embodiments do not limit the scope of the invention according to the claims. Furthermore, not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention.

[0025] 1A shows an example of the configuration of a cardiac massage trainer 200. The cardiac massage trainer 200 of this example includes an evaluation device 100 and a container 110.

[0026] The container 110 is flexible and is repeatedly compressed and decompressed during cardiac massage training. For example, the container 110 is a plastic bottle. The container 110 may be a commercially available plastic bottle for beverages, rather than a dedicated product. The container 110 may be another container made of a resin such as olefin. The container 110 has an opening to which the evaluation device 100 is attached. The opening of the container 110 may be sealed by the evaluation device 100. The inside of the container 110 may be filled with a gas such as air, or may be partially filled with a liquid.

[0027] The evaluation device 100 measures the internal pressure value Pc of the container 110 during cardiac massage training and evaluates the quality of the cardiac massage operation. The evaluation device 100 of this example includes a lid body 10 attached to the opening of the container 110. The specific configuration of the evaluation device 100 will be described later.

[0028] The lid body 10 is attached to the opening of the container 110. The material of the lid body 10 is resin in one example, but is not particularly limited to this. The lid body 10 in this example has a shape like a cap that is attached to the container 110. The lid body 10 is detachably attached to the container 110. For example, the lid body 10 is attached to the container 110 by screw fastening.

[0029] FIG. 1B shows an example of a training method using the cardiac massage training device 200 by a user 300. The user 300 practices cardiac massage by imagining the sides of the container 110 as the chest of a human body. The user 300 presses the sides of the container 110 at predetermined intervals. The user 300 practices applying appropriate pressure to the chest, releasing pressure after applying pressure, and continuously repeating these movements at correct intervals. The evaluation device 100 evaluates the quality of the cardiac massage movements and provides feedback to the user 300, guiding the user 300 to keep their cardiac massage movements within an appropriate range. The cardiac massage training device 200 of this example can be made smaller than a cardiac massage training doll, making it easier to carry and store.

[0030] 2 is an example of a block diagram showing the configuration of the evaluation device 100. The evaluation device 100 includes an acquisition unit 20, a sensor unit 30, a conversion unit 40, an evaluation unit 50, and an output unit 60.

[0031] The acquisition unit 20 acquires container-related information Ic related to the container 110. For example, the container-related information Ic includes information related to the type of the container 110. The information related to the type of the container 110 may include information related to the material of the container 110, and may include information related to the shape, thickness, or size of the container 110. The container-related information Ic may include information related to the container rigidity of the container 110. The container-related information Ic may include information related to the container rigidity depending on the number of times the container 110 has been pressed. The container rigidity of the container 110 will be described later.

[0032] The sensor unit 30 has a sensor for detecting information relating to the state of the cardiac massage training device 200. The sensor unit 30 of this example has a pressure sensor 32 for detecting the internal pressure value Pc of the container 110. The sensor unit 30 of this example is provided in the lid main body 10. However, the sensor unit 30 may also be provided outside the lid main body 10 to obtain information outside the lid main body 10.

[0033] The pressure sensor 32 may be any type capable of detecting the internal pressure value Pc of the container 110, and the method of detecting the pressure is not particularly limited. The internal pressure value Pc of the container 110 increases when the container 110 is pressed, and decreases when the container 110 is depressurized. The pressure sensor 32 may be of any type, such as a piezo-resistance type, a capacitance type, a strain gauge type, a metal gauge type, a semiconductor gauge type, or a semiconductor diaphragm type.

[0034] The conversion unit 40 converts the internal pressure value Pc measured by the pressure sensor 32 into a pressing force value Pp. The pressing force value Pp is the force applied to the container 110 by cardiac massage. In this example, the conversion unit 40 calculates a corrected pressing force value Pp in accordance with the container-related information Ic. For example, the conversion unit 40 converts the internal pressure value Pc acquired by the pressure sensor 32 into a pressing force value Pp based on a conversion table, which is created in advance for each type of container 110 and shows the relationship between the internal pressure value Pc and the pressing force value Pp. The conversion table may be created based on experiments conducted in a constant temperature environment. Alternatively, the conversion table may be created by linearly interpolating experimental data. The conversion table may be acquired by the acquisition unit 20 as the container-related information Ic, or may be generated by the conversion unit 40. Alternatively, the conversion table may be stored in advance in the conversion unit 40. The conversion table may be corrected in accordance with the container-related information Ic. The conversion unit 40 may store the conversion table in advance and select necessary data in accordance with the container-related information Ic. The conversion table may be stored in a memory external to the conversion unit 40.

[0035] The evaluation unit 50 generates an evaluation result Re that evaluates the quality of the cardiac massage based on the pressure value Pp. For example, the evaluation unit 50 evaluates at least one of the timing and strength of the cardiac massage. The evaluation unit 50 may calculate the strength of the cardiac massage based on the pressure value Pp and the container-related information Ic. In this example, the evaluation unit 50 evaluates the quality of the cardiac massage by evaluating the pressure value Pp converted by the conversion unit 40. Note that the evaluation unit 50 may also evaluate the quality of the cardiac massage based on the container-related information Ic and the internal pressure value Pc without using the conversion unit 40. In this case, the evaluation unit 50 may include a table that evaluates the quality of the cardiac massage according to the internal pressure value Pc for each type of container 110.

[0036] The output unit 60 outputs an output signal according to the evaluation result Re by the evaluation unit 50. The output unit 60 outputs the output signal according to the evaluation result Re to the user 300, thereby providing feedback to the user 300 on the quality of the cardiac massage. The output signal may be any of an optical signal, an audio signal, an image signal, or the like. The output unit 60 may also output information to the user 300 for improving the cardiac massage. For example, the output unit 60 outputs a signal indicating the timing of compression or decompression of the cardiac massage. The output unit 60 may notify the user 300 of the timing of compression by emitting light. The output unit 60 may also provide feedback to the user 300 on the strength of the pressure value Pp so as to improve the cardiac massage.

[0037] The cardiac massage training device 200 of this example converts the internal pressure value Pc into a pressure force value Pp based on the container-related information Ic to evaluate the quality of cardiac massage. This allows for a more accurate evaluation of cardiac massage depending on the container 110 used.

[0038] 3A shows an example of a specific configuration of the evaluation device 100. In this example, a cross section of the evaluation device 100 is shown. The evaluation device 100 in this example is removed from the container 110. The main body 12, the lid 14, and the hinge 16 form the lid main body 10. The acquisition unit 20 in this example has an input unit 22.

[0039] The main body 12 is connected to a lid 14 that is provided so as to be able to open and close by a hinge 16. A screw portion 70 is provided inside the main body 12 for connecting to a container 110. The main body 12 houses a sensor unit 30, a circuit board 80, a power supply unit 90, etc.

[0040] The screw portion 70 is attached to the opening of the container 110. The screw portion 70 may be a female screw of a size that can be attached to the opening of a plastic beverage bottle. In this example, the screw portion 70 is a female screw, but it may also be a male screw. Note that the lid main body 10 may be attached to the container 110 by a method other than screw fastening.

[0041] The sensor unit 30 is connected to the inside of the container 110 via a measurement pressure introducing hole 72. This allows the pressure sensor 32 of the sensor unit 30 to measure the internal pressure value Pc of the container 110. The sensor unit 30 may include sensors other than the pressure sensor 32. A sealing unit 76 such as a seal may be provided between the measurement pressure introducing hole 72 and the main body unit 12 to hermetically seal the inside of the container 110. In this example, an atmosphere introducing hole 74 is provided in the lid unit 14, and the sensor unit 30 measures the internal pressure value Pc as a gauge pressure based on atmospheric pressure.

[0042] The circuit board 80 is equipped with a processing unit 82 and a memory unit 84. The circuit board 80 of this example is equipped with the sensor unit 30 on the surface opposite to the surface on which the processing unit 82 and memory unit 84 are equipped. The processing unit 82 may function as an arithmetic processing device such as a CPU. The memory unit 84 may function as an information storage device such as a memory. The evaluation unit 50 may be implemented in the processing unit 82 and memory unit 84. Similarly, other functions such as the conversion unit 40 may also be implemented in the processing unit 82 and memory unit 84. The processing unit 82 may be configured with a digital circuit or an analog circuit. The circuit board 80 of this example is electrically connected to the output unit 60 and the power supply unit 90 by wiring cables.

[0043] The output unit 60 has a light source 62 and a speaker 64. The light source 62 emits light according to the evaluation result Re. The light source 62 may emit light of a color according to the evaluation result Re. In one example, the light source 62 emits light of a predetermined color when cardiac massage is appropriate. The light source 62 may emit light according to the timing of cardiac massage so that compression or decompression is performed at the appropriate timing.

[0044] The speaker 64 emits sound corresponding to the evaluation result Re through the speaker hole 66. The speaker 64 may emit sound corresponding to the evaluation result Re. In one example, the speaker 64 emits a predetermined sound when cardiac massage is appropriate. The speaker 64 may emit sound according to the timing of cardiac massage so that compression or release is performed at the appropriate timing. The light source 62 and the speaker 64 are examples of the output unit 60, and are not limited to these. The output unit 60 may convey information to the user 300 by display or vibration. The output unit 60 may be provided outside the lid main body 10.

[0045] The input unit 22 is operated by the user 300 or the like to input predetermined information. For example, the input unit 22 is a touch panel for inputting the container-related information Ic. The input unit 22 is not limited to any device as long as it can input information. The input unit 22 may have a button for inputting information near the display. The input unit 22 may be a touch panel for displaying information for setting the type of container 110 or the cardiac massage training mode, etc. In one example, the input unit 22 displays a screen for selecting and inputting an adult or child as the target of cardiac massage in order to set the cardiac massage training mode. The input unit 22 may also function as a display unit for visually displaying information corresponding to the evaluation result Re.

[0046] FIG. 3B shows an example of the appearance of the evaluation device 100. The evaluation device 100 has an input unit 22 on the side of the main body 12. The input unit 22 in this example is a touch panel for displaying information for acquiring the container-related information Ic. The input unit 22 may be arranged so as to face the user 300 while the cardiac massage training device 200 is in use. The input unit 22 may display whether the cardiac massage action is good or bad. The input unit 22 may also display whether the pressing force value Pp is good or bad and whether the timing of the cardiac massage is good or bad. The display method of the input unit 22 will be described in detail later.

[0047] 3C shows an example of the appearance of the evaluation device 100. The evaluation device 100 has a light source 62 and a speaker hole 66 on the side of the main body 12. The light source 62 is arranged in a position where the user 300 can recognize the light while using the cardiac massage training device 200. The number and arrangement of the light sources 62 and speaker holes 66 are not limited to this.

[0048] 4A is a cross-sectional view illustrating an absolute pressure type pressure sensor 32. The pressure sensor 32 of this example has a diaphragm 36 connected to the inside of the container 110 via a measurement pressure introducing hole 72. The pressure sensor 32 acquires an internal pressure value Pc of the container 110 using the diaphragm 36. The conversion unit 40 may calculate the pressing force value Pp based on a conversion table for converting the internal pressure value Pc of absolute pressure into a pressing force value Pp.

[0049] 4B is a cross-sectional view illustrating the differential pressure type pressure sensor 32. The pressure sensor 32 of this example has an atmosphere inlet hole 74 connected to the outside of the evaluation device 100. One surface of the diaphragm 36 is exposed to the measurement pressure inlet hole 72, and the other surface is exposed to the atmosphere inlet hole 74. This allows the pressure sensor 32 to obtain an internal pressure value Pc as a gauge pressure based on atmospheric pressure. The conversion unit 40 may calculate the pressing force value Pp based on a conversion table for converting the internal pressure value Pc of the gauge pressure into a pressing force value Pp.

[0050] 5A is a diagram illustrating the relationship between the pressure value Pp and the internal pressure value Pc. When the container 110 is pressed from the outside with the pressure value Pp, the internal pressure value Pc changes in accordance with the change in the volume of the container 110. A cardiac massage requires a pressure of, for example, about 50 kgf to 60 kgf, and a pressure value Pp that satisfies this is necessary. In other words, since the appropriateness of cardiac massage is evaluated based on the pressure value Pp, it is necessary to convert the measured internal pressure value Pc into the pressure value Pp, or convert the required pressure value Pp into the internal pressure value Pc.

[0051] Here, the sealed container 110 can be thought of as being replaced with a piston as shown in this figure. In this case, the magnitude of the pressure applied to the piston corresponds to the pressure value Pp, and the pressure inside the piston corresponds to the internal pressure value Pc.

[0052] 5B is a diagram illustrating the relationship between the pressing force value Pp and the internal pressure value Pc. If the sealed container 110 is considered as a piston, the pressing force value Pp and the internal pressure value Pc are proportional to each other. Therefore, whether the user 300 is pressing the container 110 with an appropriate pressing force value Pp can be evaluated by converting the internal pressure value Pc acquired by the pressure sensor 32 into the pressing force value Pp. For example, when the pressing force value Pp is F, the internal pressure value Pc is P, and when the pressing force value Pp is 2F, the internal pressure value Pc is 2P.

[0053] The evaluation device 100 may store in advance experimental values ​​of the relationship between the pressing force value Pp and the internal pressure value Pc for each type of container 110. That is, the evaluation device 100 may store experimental data showing the relationship between the pressing force value Pp and the internal pressure value Pc. The conversion unit 40 may convert the internal pressure value Pc detected by the pressure sensor 32 into the pressing force value Pp based on the container-related information Ic.

[0054] 6 is a graph illustrating a method for evaluating the quality of cardiac massage. The graph shows the waveform of the pressure value Pp applied to the container 110. TP1 to TP4 indicate the timings at which pressure should be applied to the container 110. TD1 to TD4 indicate the timings at which pressure should be released from the container 110. In an appropriate cardiac massage, the pressurization timing TP and the depressurization timing TD are repeated at predetermined time intervals Ti.

[0055] The time interval Ti may be set to, for example, a range of 100 to 120 times per minute to match the appropriate timing of cardiac massage. The width of the pressure application timing TP may be large enough to allow the user 300 to time the peak of the pressure value Pp, for example, about 0.1 seconds. If the width of the pressure application timing TP is made too narrow, it will be difficult for the user 300 to time the peak of the pressure value Pp with the pressure application timing TP.

[0056] The evaluation unit 50 evaluates the quality of the cardiac massage operation by determining whether the maximum value of the pressure value Pp during the time interval Ti reaches a predetermined threshold value. For example, the evaluation unit 50 evaluates that the pressure is appropriate when the pressure value Pp during pressure application is equal to or greater than a predetermined first threshold value P1, and evaluates that the pressure is insufficient when the pressure value Pp during pressure application is less than the first threshold value P1. The evaluation unit 50 may also evaluate that the decompression is appropriate when the pressure value Pp during decompression is less than a second threshold value P2, and evaluate that the decompression is insufficient when the pressure value Pp during decompression is equal to or greater than the second threshold value P2.

[0057] The first threshold P1 is, for example, approximately 50 kgf to 60 kgf. The first threshold P1 may be changed depending on whether the subject of cardiac massage is an adult or a child, etc. The second threshold P2 may be 0 kgf or greater. In one example, the second threshold P2 may be 1 kgf. Setting the second threshold P2 to 0 kgf or greater prevents erroneous determination of whether decompression has been achieved due to errors in the reading of the pressure sensor 32 or errors caused by changes in atmospheric pressure in the usage environment. The second threshold P2 may also be changed based on the container-related information Ic. By changing the second threshold P2 based on the container-related information Ic, it is possible to determine whether decompression has been achieved, as described below.

[0058] At the pressurization timing TP1, the peak of the pressing force value Pp is equal to or greater than the first threshold value P1, so the pressing force is appropriate. Also, since the peak position of the pressing force value Pp is within the range of the pressurization timing TP1, the pressing is appropriate. At the depressurization timing TD1, the pressing force value Pp is less than the second threshold value P2, so the depressurization is appropriate.

[0059] This example also shows cases where cardiac massage is inappropriate. For example, at pressurization timing TP2, the peak position of the pressure value Pp is outside the range of pressurization timing TP2, so pressurization is inappropriate. At pressurization timing TP3, although the peak position of the pressure value Pp is within the range of pressurization timing TP3, the peak of the pressure value Pp is less than the first threshold value P1, so pressurization is inappropriate. At decompression timing TD4, the pressure value Pp is equal to or greater than the second threshold value P2, so decompression is inappropriate.

[0060] In this way, the evaluation unit 50 may evaluate the timing and intensity of compression and decompression using the first threshold value P1 and the second threshold value P2. The output unit 60 may notify the user 300 of the timing of compression and decompression. For example, the output unit 60 notifies the user 300 of the timing of compression and decompression by emitting light from the light source 62, providing audio guidance from the speaker 64, or displaying guidance on the touch panel of the input unit 22. The output unit 60 may notify the user 300 by light, audio, or the like when cardiac massage is appropriate.

[0061] 7A shows the state of the container 110 before use and the corresponding pseudo piston. Repeated pressure on the container 110 can be thought of as replacing the container 110 with a piston incorporating a spring. That is, the elastic deformation of the container 110 corresponds to the deformation of the spring, and changes in the internal pressure value Pc of the container 110 correspond to pressure changes on the piston. The pressing force value Pp corresponds to the resultant force of the deformation of the spring and the pressure changes on the piston. Furthermore, the container rigidity of the container 110 is thought to correspond to the strength of the spring.

[0062] L0 indicates the natural length of the spring corresponding to the state of the container 110 before use. k0 is the spring constant of the spring corresponding to the state of the container 110 before use. The natural length L0 and spring constant k0 of the spring may be determined depending on the material, shape, etc. of the container 110. The conversion unit 40 may acquire information on the natural length L0, spring constant k0, and piston cross-sectional area A of the spring for each type of container 110 in advance. In this case, the stroke value of the piston converted from the change in the internal pressure value Pc may be used as the displacement amount of the spring. For example, when the internal pressure value Pc doubles from the initial state, the stroke amount can be calculated as 0.5 × L0.

[0063] FIG. 7B shows the state of the container 110 after deformation and the corresponding pseudo-piston. Ideally, the state of the piston would not change even when the container 110 is used. However, in reality, the state of the piston may change when the container 110 is used due to plastic deformation of the container 110. For example, if the container 110 is pressurized and deformed and does not return to its original shape, this may correspond to a state in which the piston is fixed and does not return to its initial position. In this example, the piston is fixed at the position of spring length L1 and does not return to its initial position. In this case, the internal pressure value Pc when pressurized remains unchanged from before deformation, but the internal pressure value Pc when depressurized becomes greater than atmospheric pressure.

[0064] The evaluation unit 50 may change the value of the second threshold P2 depending on the container-related information Ic. The evaluation unit 50 may change the second threshold P2 depending on the type of the container 110. Furthermore, the evaluation unit 50 may change the second threshold P2 depending on the shape or container rigidity of the container 110.

[0065] Here, if the pressure value Pp converted from the internal pressure value Pc during decompression exceeds zero, it will exceed the second threshold value P2, even if the user 300 has accurately decompressed the container 110, making it more likely to result in an erroneous determination. Furthermore, plastic deformation of the container 110 is more likely to occur depending on the shape and rigidity of the container 110. When a container 110 prone to plastic deformation is used, the evaluation unit 50 can prevent erroneous determination by setting the second threshold value P2 to a higher value. For example, if the container 110 is rectangular, creases are more likely to occur and the container 110 is more likely to deform, so the second threshold value P2 may be set higher than when the container 110 is round.

[0066] 7C shows the state of container 110 after repeated deformation and the corresponding pseudo-piston. Due to repeated deformation, container 110 has become softer than before use. That is, the spring constant of the pseudo-spring in container 110 is lower, with spring constant k2 being smaller than spring constant k0. Therefore, after repeated deformation, container 110 is more easily deformed than before use.

[0067] In this way, the evaluation device 100 can read changes in the internal pressure value Pc using the pressure sensor 32, and can therefore flexibly respond to changes in the state of the container 110. The evaluation device 100 may also correct the pressing force value Pp according to the number of times pressing is performed. The evaluation device 100 may count up the number of times pressing is performed each time pressing of the container 110 is detected. The conversion unit 40 may pre-store, as the container-related information Ic, information indicating changes in the state of the container 110 according to the number of times pressing is performed, and correct the pressing force value Pp based on the measured number of times pressing is performed. This makes it possible to correct changes in the state of the container 110 due to repeated use.

[0068] Fig. 8A shows a modified example of the evaluation device 100. This example differs from the embodiment in Fig. 2 in that the sensor unit 30 has a temperature sensor 34. This example will be described in particular in terms of the differences from the embodiment in Fig. 2.

[0069] The temperature sensor 34 detects the internal temperature Tc of the container 110. The conversion unit 40 calculates the pressing force value Pp corrected according to the internal temperature Tc. In this example, the conversion unit 40 calculates the pressing force value Pp corrected according to the container-related information Ic and the internal temperature Tc. The type of the temperature sensor 34 may be a semiconductor temperature sensor, a resistance temperature detector, a linear resistor, a thermistor, a thermocouple, or an infrared intensity sensor.

[0070] When the internal temperature Tc becomes higher than a predetermined reference temperature (e.g., room temperature), the conversion unit 40 may correct the pressing force value Pp so as to suppress the influence of the internal temperature Tc on the internal pressure value Pc. The conversion unit 40 may store the internal temperature Tc measured by the temperature sensor 34 when the pressure sensor 32 acquires the maximum pressure.

[0071] FIG. 8B is a diagram illustrating the effect of a temperature rise in the container 110. Repeated pressure on the container 110 can cause the temperature of the container 110 to rise. For example, the temperature of the container 110 can rise due to the effects of heat from the user's 300 hand, heat from deformation of the container 110, and adiabatic compression of the air. In this way, the internal pressure value Pc can also rise due to a temperature rise in the container 110 that is unrelated to the pressure value Pp. The cardiac massage training device 200a shows the state before use. The cardiac massage training device 200b shows the state after the temperature has risen.

[0072] Here, consider the case where the pressure and temperature of the container 110 before use are P0 and T0, and the pressure and temperature of the container 110 after the temperature rise are P1 and T1. If the volume V of the container 110 is the same before use and after the temperature rise, then according to Boyle's law, P0V / T0=P1V / T1 is satisfied, and the following equation is derived: P0=(T0 / T1)P1 As a result, the conversion unit 40 can convert the pressure P1 measured by the pressure sensor 32 into a pressing force value Pp corresponding to the pressure P0, using the temperature T1 measured by the temperature sensor .

[0073] The cardiac massage training instrument 200 of this example can correct the pressing force value Pp according to the internal temperature Tc in addition to the internal pressure value Pc of the container 110. This allows the cardiac massage training instrument 200 to evaluate the cardiac massage action with even higher accuracy.

[0074] FIG. 9 shows an example of a method for inputting container-related information Ic using the input unit 22. The input unit 22 in this example displays the type of container 110 and allows the user 300 to select it. The input unit 22 may display the product name, product category, shape, size, or appearance of the container 110 on a touch panel. The input unit 22 may display information such as tea, carbonated water, or water as the product. The input unit 22 may display information such as square, round, or beaded as the shape of the container 110. The input unit 22 may display information such as 500 ml or 1000 ml as the size of the container 110.

[0075] The user 300 inputs the container-related information Ic of the container 110 to be used in accordance with the display of the input unit 22. The user 300 selects the container-related information Ic corresponding to the container 110 to be used by operating the touch panel displayed on the input unit 22. The evaluation device 100 can estimate the container rigidity or a change in the container rigidity by clarifying the type of the container 110, etc. This improves the accuracy of the conversion by the conversion unit 40.

[0076] 10A shows an example of a method for inputting container-related information Ic using the input unit 22. The input unit 22 in this example displays pre-defined types of containers 110. For example, the input unit 22 displays information identifying a dedicated container, such as container A or container B. By designating the container 110 as a dedicated container, it is possible to reliably identify information such as rigidity information of the container 110.

[0077] 10B shows an example of a method for inputting container-related information Ic using the input unit 22. The input unit 22 in this example displays the container rigidity of the container 110 and allows the user 300 to select it. For example, the input unit 22 displays information such as hard, normal, soft, etc. as the rigidity type of the container 110. The input unit 22 may also display information such that other container-related information Ic can also be set by simple touch panel operations.

[0078] 10C shows an example of a method for inputting container-related information Ic using the input unit 22. The input unit 22 in this example displays, as the type of change in rigidity of the container 110, the container rigidity according to the number of times the container 110 is pressed. For example, the input unit 22 displays information such as "hard to crush," "normal," and "easy to crush" as the type of change in rigidity of the container 110.

[0079] 11A shows a modified example of the configuration of the evaluation device 100. The acquisition unit 20 of this example has an information transfer unit 24. In this example, the conversion unit 40 and the storage unit 84 are provided outside the evaluation device 100. The acquisition unit 20 of this example is provided so as to be able to communicate with the conversion unit 40 outside the evaluation device 100. Note that the conversion unit 40 and the storage unit 84 may be provided inside the evaluation device 100.

[0080] The information transfer unit 24 transfers the container-related information Ic input via the input unit 22 to the conversion unit 40. That is, the acquisition unit 20 of this example inputs and transfers the container-related information Ic, but does not need to perform other processing of the container-related information Ic.

[0081] The conversion unit 40 selects a conversion table stored in the storage unit 84 based on the container-related information Ic. The conversion unit 40 may select a correction calculation method stored in the storage unit 84 based on the container-related information Ic. The conversion unit 40 may calculate a corrected pressing force value Pp according to the conversion table and correction calculation method acquired from the storage unit 84.

[0082] 11B shows a modified example of the configuration of the evaluation device 100. The acquisition unit 20 of this example has an information transfer unit 24. The storage unit 84 may be provided in the evaluation device 100 and may store the conversion table and correction information. The conversion unit 40 may be provided outside the evaluation device 100.

[0083] The information transfer unit 24 acquires the conversion table selected according to the container-related information Ic from the storage unit 84. The information transfer unit 24 also acquires the correction calculation method selected according to the container-related information Ic from the storage unit 84. The information transfer unit 24 transfers the data acquired from the storage unit 84 to a conversion unit 40 external to the evaluation device 100. The conversion unit 40 calculates a corrected pressing force value Pp according to the conversion table and correction calculation method acquired from the information transfer unit 24. The conversion unit 40 may transmit the calculated pressing force value Pp to the evaluation device 100.

It will be apparent to those skilled in the art that various modifications and improvements can be made to the above embodiments.
