  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  As shown in FIG. 1, the oral care training apparatus 1 according to the present embodiment includes an oral reproduction model 10, a pressure sensor 16 (contact strength detection means) attached to a dentition 11 of the oral reproduction model 10, and a pressure sensor. 16 includes a control unit 20 connected to 16 and a monitor 30 serving as output means connected to the control unit 20.

  As shown in FIG. 2, the oral reproduction model 10 is used for brushing (oral care) training in which a toothbrush (care member) is brushed (care) in the oral cavity using a toothbrush (care member). In this oral cavity reproduction model 10, the shape of the upper and lower teeth 11 constituting the oral cavity of the human body is reproduced. The oral cavity is composed of a lip (lip), tongue, upper jaw (maxilla), lower jaw (mandible), teeth, salivary glands, cheeks, and muscles and temporomandibular joints that move them. In the present embodiment, the shape of the dentition that is a part of the above-described elements constituting the oral cavity is reproduced. The reproduced dentition 11 is an adult model, and is composed of 28 teeth. The dentition 11 according to the present embodiment is classified into four groups: a lower left dentition 11a, a lower right dentition 11b, an upper left dentition 11c, and an upper right dentition 11d. Toothbrushing training using the oral reproduction model 10 includes a plurality of steps of brushing 28 teeth in a predetermined order. Each step consists of brushing each tooth.

  The pressure sensor 16 detects the pressure (contact strength) applied to each tooth by contact with the toothbrush. The pressure sensors 16 are attached in pairs to the front and back surfaces of the side surfaces of the individual teeth constituting the dentition 11 of the oral cavity reproduction model 10, for a total of 56. As the pressure sensor 16, a capacitive pressure sensor (for example, FSR400: manufactured by Interlink) is employed. The pressure sensor 16 has a thin film-like appearance with a thickness of 0.35 mm, and is affixed to both the front and back surfaces without impairing the original shape of the teeth. The pressure sensitive range of the pressure sensor 16 is 0.1N to 20N, that is, about 10 g to about 2 kg. Therefore, it is possible to detect not only the brushing force (50 g to 100 g) that is generally optimum, but also a minimal brushing force or a force that greatly exceeds the optimum value, and can be sufficiently applied to the evaluation of procedures related to brushing.

  Based on the pressure detected by the pressure sensor 16, the controller 20 evaluates the appropriateness of the brushing procedure (the order of the brushed teeth). The control unit 20 includes a storage unit (storage unit) 21 and an evaluation unit (evaluation unit) 22. In addition, the memory | storage part 21 and the evaluation part 22 are mutually connected electrically, and can transmit / receive various data including the data which show the detected value of a pressure mutually.

  The storage unit 21 stores model data serving as a reference for evaluation. The exemplary data includes data indicating an appropriate value of the pressure applied to each tooth by the toothbrush and data indicating an appropriate order of brushing for a plurality of teeth. For example, in the dentition 11a, data indicating the order in which the front side is brushed from the front to the back and then the back side is brushed from the back to the front is included in the model data as appropriate order data. The evaluation unit 22 compares the model data stored in the storage unit 21 with the detected pressure value detected by the pressure sensor 16. And the evaluation part 22 evaluates the procedure of the brushing performed with respect to the oral cavity reproduction model 10 according to the order in which the pressure according to an appropriate value is detected in the several pressure sensor 16. FIG.

  The monitor 30 outputs the evaluation result by the evaluation unit 22. As shown in FIG. 3, the monitor 30 includes a dialog A1 for displaying the user (trainee), a control A2 for displaying the acquired data in real time, a schematic diagram A3 of the dentition, and a control A4 for displaying the evaluation result of the procedure. Each is arranged. Since the acquired data is stored in a file unique to the trainee, the trainee can review the record of the procedure at any time.

  Next, a method for evaluating a brushing procedure using the oral care training apparatus 1 according to the present embodiment will be described.

  First, the trainee brushes the front side from the front to the back in the tooth row 11a of the four tooth rows 11 (see FIG. 4), and then brushes the back side from the back to the front. At this time, a pair of pressure sensors 16 attached to each tooth detects the pressure applied from the toothbrush. In FIG. 4, the pressure sensor 16 is represented by dots for convenience of explanation. The pressure detected by the pair of pressure sensors 16 is represented by a graph shown in FIG. 5, for example. In this graph, the horizontal axis represents time, and the vertical axis represents pressure. The solid line graph L1 indicates the pressure applied to the first molar tooth 12a in the dentition 11a, and the dotted line graph L2 indicates the pressure applied to the side incisor 12b in the dentition 11a.

  The evaluation unit 22 compares the model data stored in the storage unit 21 with the detected pressure value detected by the pressure sensor 16, and determines that the tooth is brushed if the detected value is equal to or greater than the appropriate value of the model data. To do. The model data includes data indicating an appropriate range consisting of an appropriate upper limit value and an appropriate lower limit value instead of an appropriate value, and the pressure detection value is within the appropriate range based on a comparison between this data and the detected value. It may be determined that the tooth has been brushed. Then, by comparing the order in which it is determined that the plurality of teeth are brushed with the order of brushing indicated by the model data, the front side is brushed from the front to the back in the dentition 11a, and the back side is then moved from the back to the front. Evaluate if brushing towards.

  Next, the trainee brushes the front side from the front to the back in the tooth row 11b of the four tooth rows 11, and then brushes the back side from the back to the front. At this time, as described above, the pair of pressure sensors 16 detects the pressure applied from the toothbrush, and in the tooth row 11b, the evaluation unit 22 is brushed from the front side to the back side, and then the back side is from the back side to the front side. Evaluate if brushing towards. The same evaluation is performed in the order of the tooth row 11c and the tooth row 11d.

  By making these determinations, it is possible to evaluate whether or not the teeth are brushed with an appropriate force equal to or greater than an appropriate value. Further, whether or not the tooth row 11 is brushed in an appropriate order by comparing the order of brushing of the model data as an example stored in the storage unit 21 and the order of the teeth determined to be brushed. To evaluate. In these evaluations, for example, with respect to the order according to the model data, after the deviation of the order performed in the procedure is scored or ranked, the score and ranking results are displayed on the monitor 30. Is displayed. The trainee can recognize the appropriateness of his / her own brushing by referring to the evaluation displayed on the monitor 30.

  As described above, in the oral care training apparatus 1 according to the present embodiment, the evaluation unit 22 uses a plurality of pressure sensors based on the comparison between the model data stored in the storage unit 21 and the pressure value detected by the pressure sensor 16. According to the order in which pressure is detected by 16, the time series steps in oral care performed on the oral reproduction model 10 are evaluated. Thereby, in the oral care performed over several steps, such as tooth brushing, the order of the brushed teeth can be evaluated in time series. In this way, a device suitable for training the flow of the entire oral care is realized.

<Modification 1>
In the said embodiment, the evaluation part 22 compared the model data memorize | stored in the memory | storage part 21, and the detected value detected by the pressure sensor 16, and evaluated the procedure in several steps of toothpaste. In addition to this, in the oral care training apparatus according to the first modification, the evaluation unit 22 evaluates a temporary point in one step of tooth brushing based on the pressure distribution (contact strength distribution) applied to the dentition 11.

  In the first modification, the control unit 20 includes a creation unit (not shown) that creates a pressure distribution in addition to the storage unit 21 and the evaluation unit 22. The memory | storage part 21, the evaluation part 22, and the preparation part are electrically connected, and mutually transmit / receive various data. In the above embodiment, a pair of pressure sensors 16 are attached to the front and back of one tooth, but in Modification 1, a plurality of pressure sensors 16 are attached to one surface of one tooth. Specifically, as shown in FIG. 6, three pressure sensors 16 are attached to the occlusal surface of one tooth 12a on a straight line in plan view. In Modification 1, three pressure sensors 16 are attached to all teeth. In FIG. 6, only the first molar 12 a to which the three pressure sensors 16 are attached is shown as a representative.

  The creating unit creates a pressure distribution (see FIG. 7) at a point in time during one step of tooth brushing based on the detected pressure value at each position on the surface of the dentition. In the storage unit 21, distribution data indicating an appropriate value of the pressure distribution is stored in association with the position and the angle. The appropriate value of the pressure distribution indicates an appropriate range including an appropriate upper limit value and an appropriate lower limit value of the detected value in each of the plurality of pressure sensors 16. When each detected value in the pressure distribution in the plurality of pressure sensors 16 falls within each appropriate range indicated by the distribution data associated with a predetermined position and a predetermined angle, the toothbrush is set at a predetermined position of the tooth. It can be determined that it is applied at an angle. Further, the model data includes position / angle data indicating an appropriate value of the position and angle at which the toothbrush contacts the tooth row 11.

  With the above configuration, the evaluation unit 22 is based on the comparison between the pressure distribution created by the creation unit and the distribution data in the storage unit 21, and the positions P1 to P8 where the toothbrush 13 contacts the tooth row 11 as shown in FIG. And the angle θ is determined. Then, the evaluation unit 22 compares the determined positions P1 to P8 and the angle θ with the position / angle data included in the model data, and evaluates the suitability of the position and angle of the toothbrush at a certain temporary point.

  As described above, in the oral care training apparatus according to the first modification, the evaluation unit 22 performs an evaluation based on the pressure distribution at one point in one step of tooth brushing. Thereby, in addition to the evaluation of the procedure of brushing performed over a plurality of steps, the brushing at a specific point in time can be evaluated.

  In the oral care training apparatus according to the first modification, the evaluation unit 22 determines the positions P1 to P8 and the angle θ of the dentition that the toothbrush 13 contacts. Thus, in addition to evaluating the order of the brushed teeth, the positions P1 to P8 and the angle θ of the toothbrush 13 in contact with the tooth row are determined, so that tooth brushing can be evaluated from various angles.

  In the first modification, after the position and angle at which the toothbrush contacts the tooth or the tooth row are once determined based on the pressure distribution, the determined position and angle are compared with the model data. On the other hand, the position and angle at which the toothbrush contacts may not be determined, and the evaluation may be performed based on a direct comparison between the pressure distribution detected by the pressure sensor 16 and the pressure distribution indicated by the model data.

<Modification 2>
In the oral care training apparatus according to the first modification, the detected pressure value at one point of time in a plurality of steps was evaluated. In addition, in the oral care training apparatus according to the modified example 2, the pressure detection values in the time zones corresponding to some steps are evaluated among the pressure data detected in a plurality of steps in tooth brushing. The detected pressure value in the time zone corresponding to some steps is, for example, when the pressure sensor 16 brushes the lower left dentition 11a, particularly during the time zone when the toothbrush is brushing the first molar 12a. The detected pressure value.

  Thereby, in the training apparatus for oral care of the modification 2, while evaluating the procedure of the whole toothbrushing, how to apply the toothbrush with respect to a specific tooth, for example, the time change of the position and angle of a toothbrush with respect to a specific tooth can be evaluated.

<Modification 3>
In the above-described embodiment, the oral care training device is applied to brushing the teeth using a toothbrush. On the other hand, in the third modification, the oral care training device can be successfully used by placing a spoon on an appropriate part of the oral cavity for a person with weak food intake ability and sliding the spoon out of the mouth. Applies to the spoon technique for swallowing.

  In the oral cavity reproduction model of Modification 3, the upper and lower lips and the tongue are reproduced. And the pressure sensor 16 is attached to the appropriate place of the upper and lower lips and tongue. The memory | storage part 21 memorize | stores the model data used as the reference | standard of evaluation of spoon technique. The model data includes data indicating an appropriate value of the pressure applied to the tongue when the lip is applied by the spoon, and data indicating the order in which the lip and the pressure are applied to the tongue (for example, the order of the tongue → the lip). . The evaluation unit 22 compares the model data stored in the storage unit 21 with the detected pressure value detected by the pressure sensor 16. And the evaluation part 22 evaluates the procedure of the spoon technique performed with respect to the oral cavity reproduction model 10 according to the order in which the pressure according to an appropriate value is detected in the plurality of pressure sensors 16.

  In the spoon technique, the trainee first inserts a spoon into the oral cavity of the oral reproduction model 10. Next, place the spoon on the tongue and slide it out of the oral cavity in contact with the upper lip. At this time, after the pressure sensor 16 attached to the tongue detects the pressure applied by the spoon, the pressure sensor 16 attached to the upper lip detects the pressure applied by the spoon. The evaluation unit 22 compares the model data stored in the storage unit 21 with the detected pressure value detected by the pressure sensor 16, and if the detected data is equal to or greater than the appropriate value of the model data, a spoon is placed on the tongue. It is determined that the spoon has touched or the upper lip has touched. And it is evaluated whether the spoon technique is appropriately implemented by comparing the order in which it was determined that the spoon contacted with the order indicated by the model data (tongue → lip).

  Thus, in the oral care training apparatus of the third modification, the spoon technique can be evaluated in time series. In addition to the above configuration, a plurality of pressure sensors 16 may be attached to each of the lips and the tongue, and the pressure distribution on each of the lips and the tongue may be evaluated in more detail.
