It is a figure which shows the structure of embodiment (chest armpit complaint). It is a figure which shows the structure of embodiment (lower heart whip).

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments described herein.

  FIG. 1 is a photograph showing an overall perspective view of an abdominal model for Chinese medicine according to one embodiment of the present invention.

  Thus, the Kampo medicine abdomen model 10 according to the present embodiment has a shape imitating a part of the abdomen and chest of the human body. The back surface, the upper body side end surface, and the lower body side end surface are flat surfaces. The surface and the left and right sides are shaped like a human body. The abdomen model 10 for Kampo medicine is formed with a single substrate 20 made of, for example, foamed vinyl chloride on the back side, and the upper body side end surface and the lower body side end surface are also made of the same material as the back substrate 20. Has been. Although foamed vinyl chloride is used for the substrate 20 and the like from the viewpoint of lightness and strength, other materials may be used.

  And the surface and both left and right side surfaces are covered with a skin member 12 made of silicon resin shaped like a human body. The connecting portions of the skin member 12 with the back surface (substrate 20), the upper body side end surface, and the lower body side end surface are securely fixed by appropriate means such as double-sided tape. Further, the skin member 12 has a skin color similar to that of the human skin at least on the surface and on both the left and right side surfaces. This skin color is preferably performed by mixing a colorant into the silicone resin, but a paint may be applied to the surface.

  By changing the contents of the Kampo medicine abdomen model 10, it is possible to form a diagnostic model for various symptoms even if the appearance is the same.

<Basic configuration>
2A and 2B are schematic cross-sectional and plan views of the Chinese medicine abdominal model 10. Thus, the Chinese medicine abdominal model 10 according to the present embodiment basically includes the substrate 20, the internal organ member 28, and the skin member 12 that covers the surface of the internal organ member 28. Further, as described above, the upper body side end surface and the lower body side end surface are formed of a plate made of the same material as the substrate.

  On the upper body side, a sternum (rib) member 24 is disposed between the skin member 12 and the visceral member 28. The rib / sternum member 24 simulates the rib, and is disposed at a position corresponding to the position of the human rib. In addition, although the rib / sternum member 24 does not appear in the cross section, it is drawn so as to be present from the side to the top in the drawing. Further, a pelvic member 26 extending upward from the substrate 20 is provided on the lower body side. The pelvic member 26 simulates the pelvis and is arranged at a position corresponding to the position of the human pelvis. The rib / sternum member 24 and the pelvis member 26 are made of FRP (fiber reinforced plastic) having a relatively high strength.

  The skin member 12 preferably has a tactile sensation similar to human skin and has a certain degree of elasticity. For example, it is preferable to use two layers of silicon resin. A relatively hard and thin (about 0.5 mm) surface layer is provided on the surface side, and a relatively soft and thick (for example, about 3 mm) lower layer is provided on the lower side. For this reason, silicon resins having different hardnesses can be used, but the hardness can also be adjusted by changing the amount of silicone oil added to the silicon resin material.

  Pour the surface layer silicon resin material into the mold (female mold), disperse it uniformly on the mold surface, proceed the polymerization reaction in this state to create the surface layer, and then pour the lower layer silicon resin into the In this state, the polymerization reaction is advanced to create a lower layer, thereby producing a skin member 12 having a two-layer structure. In order to accelerate the polymerization reaction, it is also preferable to heat to about 50 to 80 ° C. Thus, the surface side is relatively hard and the inner side is soft, so that a tactile sensation close to human skin can be obtained. As these silicon resins, commercially available ones can be used, and as the silicon resin for the surface layer, a relatively hard one used for forming a mold for molding is suitable. Further, as the lower layer silicon resin, it is preferable to use a silicon resin used for creating a face mask or the like.

  The substrate 20 is made of foamed vinyl chloride or the like and has a high hardness. As described above, the upper body side end surface and the lower body side end surface are also formed of plates of the same material, and are erected and fixed to both ends by bonding or the like.

  The internal member 28 is configured by laminating sheet-like urethane foam. In addition, it is also suitable to use synthetic cotton etc. for the lower (inner side) part of the internal organs member 28. Further, the strength (resistance force) can be adjusted by the thickness and number of urethane foams. Further, for urethane foam, the strength can be adjusted by providing holes, and the strength can also be adjusted by adjusting the density (number), size, etc. of the holes.

  In this embodiment, urethane foam is impregnated with silicone resin to form a partially hardened region 42 to simulate lumping. That is, by immersing the urethane foam in a liquid silicon material for a predetermined time, the urethane foam is permeated into the pores of the urethane foam and impregnated. When a predetermined portion is sufficiently impregnated with a silicon material, it is pulled up to advance a polymerization reaction to form a urethane foam impregnated with a silicon resin. The urethane foam may be impregnated by applying the silicon material with a brush or the like many times.

  By such strength adjustment and partial hardness adjustment of the internal organ member 28, various types of case-specific Kampo medical abdominal models 10 are configured. Various materials such as natural cotton can be used for the synthetic cotton, and other materials may be used for the urethane foam. However, natural cotton has a low restoring force, and considering durability, a synthetic cotton having a high restoring force is preferable.

  Moreover, it is good to arrange | position the lubricant which pinched | interposed the fine powder with the film sheet between the skin member 12, the internal organs member 28, and the rib / sternum member 24. For example, hollow particles called microballoons are suitable. For example, a glass microballoon having a particle size of several μm to several hundred μm can be adopted, but a particle size of about 50 to 60 μm is preferable. This causes slippage between the skin member 12 and the surfaces of the visceral member 28 and the rib / sternum member 24, and the skin member 12 can be moved along the surface. As a result, the sensation when the skin member 12 is pushed by hand or pushed obliquely can be made closer to the human body.

  A large number of openings 22 are formed in the substrate 20 in a matrix at equal intervals. As a result, when the skin member 12 is pressed and the internal organs member 28 is deformed, the air in the internal member 28 is discharged from the opening 22, so that an excessive repulsive force is not generated.

  Furthermore, by placing the legs 44 on the lower surface of the substrate 20, when the Chinese medicine abdominal model 10 is placed on a desk or the like, a space can be provided between the substrate 20 and the surface of the desk, Exhaust from the internal member 28 can be promoted.

  In addition, illustration of the hardening area | region 42 is abbreviate | omitted in FIG.2 (B).

<Sensor>
In the present embodiment, a large number of sensor members 50 are two-dimensionally arranged on the substrate 20 below the internal member 28. It is arranged in the entire area to be pushed by the examiner's hand. The sensor member 50 detects the pressure generated when the skin member 12 is pressed and recessed through the internal member 28. Specifically, the displacement of the upper surface of the sensor member 50 is detected as, for example, the amount of change in capacitance. The detection signals in these sensor members 50 are sent to the control unit 52 and processed there. That is, the control unit 52 displays the distribution of the pressing force for the entire abdomen on a display or the like based on the detection signal in each sensor member 50.

  For example, as shown in FIG. 3, in the display of the entire target area, the portion where the pressing force is 0 is white, and the lightness is reduced (turns black) according to the magnitude of the pressing force, or expressed by color (color Display). Moreover, the magnitude | size of a pressure can also be shown with a contour line. Furthermore, by designating a predetermined cross section, as shown in FIG. 4, it is also preferable to show the strength (magnitude) of the pressing force in the cross section as a graph (X-axis position, Y-axis pressing force strength). .

  Thus, this embodiment is an abdominal model for Chinese medicine used when simulating abdominal examination in Kampo medicine, which is formed of a flexible resin, and an epidermis member that simulates the epidermis of the abdomen, The skin member is covered at least on the surface side and is deformable by including urethane foam, and includes a visceral member that simulates the abdominal viscera, and a plate-like substrate is provided, and the visceral member is disposed on the surface of the substrate. It arrange | positions and the said skin member is arrange | positioned covering the surface and side surface of the said internal organ member.

  A predetermined symptom can be simulated by forming a region having high hardness by impregnating a selected region of the urethane foam with a silicon resin. Further, the pressing force can be detected based on the detection result of the sensor member 50. Therefore, if the pressure distribution of the skilled person is detected and stored at the time of abdominal examination, it can be easily determined whether or not the pressure of the training subject is appropriate.

  Using such abdominal model 10 for Kampo medicine, training and education for abdominal examinations by doctors, medical students, etc., abdomen for various symptoms can be obtained with a feeling close to that of contact with the human body. The abdominal examination can be experienced, and abdominal examination training and education for doctors and medical students can be effectively performed.

  Furthermore, a large number of almost identical abdominal models 10 for Chinese medicine can be manufactured. Therefore, it is possible to set a certain standard for various symptoms and basic strength of abdominal strength. There are individual differences in the diagnosis of the human body, and it is necessary to make judgments based on different criteria. However, it is also important that a standard is set for the standard judgment, and individual differences should be judged based on the standard. Thus, the Chinese medicine abdominal model 10 according to the present embodiment can contribute to the creation of a standard for such diagnosis.

  It should be noted that by impregnating the urethane foam with a silicone resin, the sensor member 50 can be disposed even in the case where the hardened region 42 is partially formed and the lump is not simulated.

The Chinese medicine abdominal model is

  In this case, the sensor unit is preferably configured by two-dimensionally arranging a plurality of strain sensors.

"Brief model (chest armpit)"
FIG. 5 shows the identification model (chest armpit complaint). In the figure, illustration of the sensor member 50 is omitted.

  Chest armpit distress is the patient's perception that there is a feeling of pressure on the right or left side of the buttocks (bottom of the ribs). This corresponds to the finding that when a finger is inserted, the patient feels pain and pressure. This site is accompanied by dull pain and a feeling of pressure, causing resistance tenderness.

  The appearance of chest dissatisfaction is composed of various tissues in the person's abdomen. It is necessary to press with a force that makes you feel.

  In this model, the upper region of the upper reinforcing adjustment member 34a made of urethane foam is impregnated with silicon resin to provide a hardened region 42 with increased strength. That is, an inverted V-shaped hardened region 42 having a width of about 60 mm is provided on the lower body side of the rib / sternum member 24. For impregnation of the urethane foam with the silicone resin, it is preferable to immerse the urethane foam in a liquid agent of the silicone resin, but the silicone resin may be applied to the urethane foam.

  Thereby, when an examiner pushes the area | region with the hardening area | region 42 of the abdominal model 10 for Chinese medicine, resistance is felt. This simulates chest-side distress.

  It is also preferable to place a pressure sensor in the hardened region 42 and complain of tenderness (notify by voice or the like) when the examiner pushes with a fingertip with a pressure higher than a predetermined pressure or puts a finger under the radial arch. is there.

"Verification Model (Tsubaki Shimochi)"
FIG. 6 shows the identification model (submandibular whip). When the patient feels the presence of a feeling of grip on the epigastric area, the doctor touches resistance at this site, and when this part is compressed, the patient is tender It is a finding that may sue.

  In the sub-whisker model, a hardened region 42 in which silicon resin is impregnated is formed on the visceral member 28 made of urethane foam having a triangular portion corresponding to the groove and on the skin member 12 side. That is, a fan-shaped hardened region 42 having a radius of 120 mm on the lower body side of the rib / sternum member 24 and a central angle of about 80 degrees is provided.

  Thereby, when an examiner pushes the hardening area | region 42 of the abdominal model 10 for Chinese medicine, resistance is felt. This simulates the sub-whisker.

<Effect of embodiment>
In the abdominal model 10 for Chinese medicine according to the present embodiment, a skin member is formed of a sheet material of silicon resin, a sheet-like urethane material is disposed inside, and a visceral member such as synthetic cotton is packed therein. And about a urethane material, hardness is partially changed by impregnating a silicon resin partially. This makes it possible to simulate induration (a lump) or a portion with enhanced resistance, and this palpation training is possible. It should be noted that not only the region where the resistance feeling is enhanced but also the region where the resistance is reduced can be simulated by entirely impregnating the silicon resin and providing a part not impregnated or changing the amount of impregnation.

  Moreover, it has the displacement sensor arrange | positioned on many planes, and detects distributions, such as a press intensity | strength, by the output of these sensors. As a result, it is possible to quantify how much force should be pressed at the time of palpation and the like, and the efficiency of palpation training can be improved.

  Quantification such as lumps can also be performed by combining with the one that changes the partial hardness of urethane.
