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

"Configuration of pulse diagnosis simulator"
1 and 2 show the overall configuration of the pulse diagnosis simulator 10, which includes a base 12 placed on a table or the like. The base 12 includes a pair of legs 14 whose lower ends are placed on a table, and a holder 16 positioned at the upper ends of the pair of legs 14.

  In this example, the legs 14 have a pair of plate-like shapes, but may have four legs or other structures as long as the holder 16 can be maintained at a predetermined position. As will be described later, the holder 16 is a relatively thick plate as a whole, and has a long and narrow groove 18 opened upward at the center of the upper surface. In this example, the cross section is rectangular, but other shapes such as a semicircle may be used. Both ends of the groove 18 have a bottom, but the central portion has no bottom, and is a slit 20 that extends to the lower surface of the holder 16.

  A cylindrical elongated blood vessel member 22 is placed in the groove 18. Both ends are supported at the bottom of the groove 18. Further, a sheet-like skin member 24 is disposed so as to cover the upper surfaces of the blood vessel member 22 and the holder 16. Then, both ends of the blood vessel member 22 are pressed against the bottom of the groove 18 by the pressing member 26 through the skin member 24. The pressing member 26 has a shape of an arm and a hand as a whole, and has an opening 28 at a wrist portion, and the holder 16 is accommodated in the opening 28. And the protrusion 30 which protrudes inside is formed in the upper end of the opening 28 of the pressing member 26, and this protrusion 30 presses the both ends of the skin member 24. FIG. By setting the size of the opening 28 to match the size of the holder 16, the pressing member 26 can be moved downward from above and fixed to the periphery of the holder 16 by friction. The pressing member 26 may be fixed to the holder 16 with a band or the like, or the pressing member 26 may be fixed with another member.

  In FIG. 2, similarly to the legs 14, the upper part of the fixing member 50 whose lower end is placed on a table or the like is fixed to the pressing member 26 by bolting, and the pressing member 26 is fixed.

  The lower portion of the opening 28 is sized according to the size of the holder 16, but the opening 28 may be increased downward. Further, although the protrusion 30 is formed so as to press at least both ends of the groove 18, it is also preferable to press the periphery of the skin member 24. In this example, on the left side in FIG. 2, the upper end of the pressing member 26 is a horizontal surface that is almost the same height as the surface of the holder 16, and on the right side, the end surface of the pressing member 26 rises vertically from the surface of the holder 16. It is a surface. The user places a hand on the skin member 24 from the left side and performs pulse diagnosis.

  Moreover, it is preferable that the protrusion 30 is inclined gently toward the opening 28 and has a shape close to the wrist.

  The upper portion of the cam member 40 is inserted into the slit 20. In the example of FIG. 1, the disc is eccentric and attached to the rotating shaft 44 of the motor 42. Accordingly, the cam member 40 is rotated by the rotation of the motor 42, and the upper end position thereof goes up and down with one rotation as a cycle. That is, the position of the disc cam member 40 indicated by the solid line is the uppermost position, and the upper end is the lowest position at the position indicated by the broken line.

  In response to such movement of the cam member 40, the blood vessel member 22 moves up and down, and the skin member 24 is pushed up accordingly. In an actual blood vessel, the blood vessel expands according to the blood flow, but in the present embodiment, this is simulated as a vertical movement of the blood vessel member 22. This makes it possible to simulate pulse diagnosis similar to actual pulsation with a simple structure.

  The rotation of the motor 42 is controlled by the controller 46. For example, if the rotation of the rotating shaft 44 is 60 rpm, the pulse rate is 60 per second. The motor 42 preferably has a predetermined speed reducer and mechanically adjusts the rotational speed of the rotary shaft 44 to an appropriate value. The controller 46 may be a slidac that changes the output voltage to control the rotation speed of the motor 42, but may be a digital control.

"Composition of cam member"
Here, in FIGS. 1 and 2, the cam member 40 is circular, but it is also preferable that an oval shape or a protrusion is provided at a predetermined portion of the circumferential portion.

  FIG. 3 shows a configuration of an example, and has three protruding portions 40a. In this case, one rotation corresponds to three pulse rates. Further, in this example, the cam member 40 rotates counterclockwise, and the protrusion 40a gradually increases in radial direction with rotation and decreases relatively quickly after the apex. And when returning to a circular peripheral surface, the inclination changes suddenly. Therefore, there is a slight shock at this time. By adopting such a shape, it is possible to obtain an interval close to the actual pulse. Further, if the radial distance of the protruding portion 40a is large, the pulsation is increased accordingly. In this way, the pulsation can be more appropriately simulated by making the shape asymmetric with respect to the protrusion 40a and the top in the rotation direction.

  Moreover, FIG. 4 is another example, and there exists a dent in the surrounding surface of the protrusion part 40a. By adopting such a shape, other types of pulsations can be obtained. In this example, one rotation corresponds to two pulses.

  By performing various detections on the pulse, obtaining data on the pulsation, and determining the outer peripheral shape of the cam member 40 based on this, it is possible to obtain an operation close to the actual pulsation. In particular, in the shape of the peripheral surface of the cam member 40, by providing a non-smooth discontinuous portion (for example, a connection portion between the terminal portion of the protrusion 40a and the circumferential surface in FIG. 3) with a large change in inclination, the pulsation is reduced. Appropriate simulation becomes possible.

  Thus, by changing the shape of the cam member 40, the waveform, amplitude, and the like of the pulsation can be changed, and an arbitrary pulsation can be simulated. Therefore, various pulsations can be simulated by preparing a plurality of cam members 40 and replacing them appropriately. Further, by forming the cam member 40 based on detection results (waveforms) of various pulsations, a more appropriate cam member 40 can be formed.

"Skin material"
FIG. 5 shows an epidermis member 24 corresponding to skin / subcutaneous tissue. Thus, the skin member 24 is formed of, for example, a rectangular sheet material. A plastic sheet material having a thickness of about 0.1 to 0.5 mm is suitable. For example, a soft urethane material or the like is used. By changing the material and the thickness, the movement state accompanying the movement of the blood vessel member 22 changes. Therefore, it is preferable to prepare a plurality of types of the skin member 24 and replace them appropriately. Various pulsations can be simulated by preparing a plurality of skin members 24 and replacing them appropriately.

`` Vessel member ''
For the blood vessel member 22, for example, a foam rubber tube, a silicon tube, a soft urethane tube, or the like is used. The soft urethane tube is the softest in the order of foamed rubber tube, silicone tube, and soft urethane tube. By preparing a plurality of types of tube diameters, it is possible to cope with thin and thick blood vessels. In the example of FIG. 6, the blood vessel member 22 is a solid cylindrical material. In the present embodiment, it is not necessary to distribute the liquid to the vascular member 22, and a solid cylindrical material can be used. Various pulsations can be simulated by preparing a plurality of blood vessel members 22 such as various materials, pipes, solids, and the like and replacing them appropriately.

  The blood vessel member 22 and the skin member 24 are separate members, and the user can sense the movement of the blood vessel member 22 through the skin member 24, and can obtain a feeling close to an actual pulse diagnosis. They can be replaced independently.

"Holding tool"
FIG. 7 shows a schematic configuration of the holder 16. As a whole, it is a rectangular parallelepiped, and a shallow groove 18 is formed on the surface, and a slit 20 is provided below the central portion. The upper part of the cam member 40 is inserted from below the slit 20. The holder 16 may be made of any material, but for example, an acrylic resin is used.

"appearance"
FIG. 8 shows the overall appearance of the pulse diagnosis simulator. As described above, the holding member 16 has the shape of an arm and a hand, and the holder 16 in which the blood vessel member 22 and the skin member 24 are set is arranged on the wrist portion. The motor 42 is housed in a motor case 48 and connected to a controller 46 formed as a separate body by a cord. The controller 46 is connected to a power cord having a plug for connecting to a commercial power source. By adjusting the knob of the controller 46, the power supply from the controller 46 to the motor 42 is controlled, and the rotation speed of the motor 42 is controlled.

"Use of pulse diagnosis simulator"
When using this pulse diagnosis simulator, a desired cam member 40 is first attached to the rotating shaft 44. About this attachment, various means can be selected suitably. For example, it is preferable to provide a key on the rotation shaft 44 and fix the cam member 40 in the rotation direction. Further, if the upper portion of the cam member 40 is inserted into the slit 20 and then tightened with a bolt or the like from the front side of the cam member 40, the positional relationship between the base 12 and the rotating shaft 44 is changed by replacing the cam member 40. Since it does not change, subsequent positioning becomes easy. The base 12 may be installed after the cam member 40.

  Next, the selected blood vessel member 22 is placed in the groove 18 of the holder 16, and the selected skin member 24 is placed thereon. Finally, the pressing member 26 is covered from above and fixed by bolting or the like.

  Then, the controller 46 controls power feeding to the motor 42 to rotate the cam member 40 at a desired number of rotations. As a result, the vascular member 22 is periodically pushed up by the cam member 40.

  In this state, the user places a finger on the skin member 24 and presses the finger to search for a pulse. As a result, if the position is appropriate, the movement of the blood vessel member 22 is sensed, and the pulse diagnosis is simulated.

  Thus, according to the present pulse diagnosis simulator, the cam member 40 and the vascular member 22 that express pulsation based on one typical finding such as the depth of the pulse, the strength of the pulse, the hardness of the blood vessel, and the size of the pulse. It can be expressed by replacing the skin member 24 and the like.

  In this way, it is possible to reproduce a plurality of findings with one apparatus. In acupuncture, pulse diagnosis is an important diagnostic finding. For this reason, pulse examinations are going to be performed all over the world. Therefore, standardization in pulse diagnosis is important. According to this pulse diagnosis simulator, standard pulse diagnosis training is possible, and this can be used as an international standard for pulse diagnosis. In modern medicine, medical examinations are performed to puncture the radial artery, and there are simulators for this purpose. However, it can be applied to simulators for carotid artery pulsation treatment in modern medicine by reproducing delicate tactile sensations like this instrument.
