Summary of the Invention

Problems to be Solved by the Invention

[0004] In order to conduct a more immersive nursing practice or medical practice, it is preferable to use a doll that is close to a real child. However, since the conventional dolls disclosed in Patent Document 1 are in a stationary state unlike a living infant, it has been difficult to conduct the practice in an immersive state. Such problems were not limited to practices targeting infants, but were the same for practices targeting children older than infants. In addition, a moving doll manufactured by providing a movable mechanism inside the doll had a very high manufacturing cost and was difficult to introduce into the practice site. For this reason, there has been a demand for a technology that can conduct a practice using a doll in an immersive state with a simple mechanism.

Means for Solving the Problems

[0005] The present disclosure can be realized in the following forms.

[0006] (1) According to one embodiment of the present disclosure, a rocking device is provided. This rocking device is for rocking a doll and comprises a mounting part on which the head of the doll is placed in the vertical direction, and a drive unit that causes the mounting part to reciprocate along a horizontal direction substantially perpendicular to the height direction of the doll. With this form of rocking device, the doll can be rocked, so that practical training using a doll can be conducted in a realistic manner with a simple mechanism.

[0007] (2) In the rocking device described in (1) above, the upper part of the mounting portion described above may be formed such that the central part in the horizontal direction is recessed vertically downward compared to the ends in the horizontal direction. With this form of rocking device, since the central part of the upper part of the mounting portion is recessed compared to the ends, the doll can be placed stably, and as a result, the doll can be prevented from shifting away from the mounting portion due to rocking.

[0008] (3) In the rocking device described in (1) or (2) above, the mounting part may reciprocate at a frequency of 1 Hz to 6 Hz. With this form of rocking device, since the mounting part reciprocates at a frequency of 1 Hz to 6 Hz, the movements of living infants can be reproduced more accurately, and as a result, practical exercises using dolls can be conducted in a more realistic state.

[0009] (4) In the rocking device described in any one of the above items (1) to (3), the mounting part described above may reciprocate with a swing amplitude of 0.8 cm to 3.4 cm along the horizontal direction. With this form of rocking device, since the mounting part reciprocates with a swing amplitude of 0.8 cm to 3.4 cm, the movements of a living infant can be reproduced more accurately, and as a result, practical training using dolls can be conducted in a more realistic state.

[0010] (5) The rocking device described in any one of the above paragraphs (1) to (4) may further include an adjustment unit that can adjust the frequency of the reciprocating motion of the mounting part. With this form of rocking device, since it includes an adjustment unit that can adjust the frequency of the reciprocating motion of the mounting part, it is possible to reproduce the movements of living infants and other young children more accurately, and as a result, practical training using dolls can be conducted in a more realistic state.

[0011] (6) The rocking device described in (5) above may further include a remote control unit that can remotely adjust the frequency of the reciprocating motion of the mounting part. With this form of rocking device, since it includes a remote control unit that can remotely adjust the frequency of the reciprocating motion of the mounting part, the degree of rocking of the doll can be easily adjusted, and as a result, practical training using dolls can be conducted in a more realistic state.

[0012] (7) The rocking device described in any one of the above paragraphs (1) to (6) may further include an audio output unit that outputs the sound of an infant crying. With this form of rocking device, since it further includes an audio output unit that outputs the sound of an infant crying, it is possible to reproduce the state of a living infant more accurately, and as a result, practical exercises using dolls can be conducted in a more realistic state.

[0013] (8) In the rocking device described in any one of the above paragraphs (1) to (7), the coefficient of dynamic friction of the upper surface of the mounting portion described above may be greater than that of the bottom surface of the mounting portion described above. With this form of rocking device, since the coefficient of dynamic friction of the upper surface of the mounting portion is large, the displacement of the doll from the mounting portion due to rocking can be further suppressed.

[0014] Furthermore, this disclosure can be implemented in various forms, for example, a method for manufacturing a rocking device for rocking a doll, a system for rocking a doll, a nursing practice kit comprising a rocking device and a doll, a medical practice kit comprising a rocking device and a doll, a method for nursing practice using a doll, a method for medical practice using a doll, and so on. [Brief explanation of the drawing]

[Figure 2] This is a schematic front view showing the external configuration of the oscillating device. [Figure 3] This is an explanatory diagram illustrating the internal structure of the rocking device. [Figure 4] This is an explanatory diagram showing an example of how the oscillating device is used. [Modes for carrying out the invention]

[0016] A. Overall configuration Figure 1 is a schematic top view showing the external configuration of the rocking device 100 as one embodiment of the present disclosure. Figure 2 is a schematic front view showing the external configuration of the rocking device 100. Figure 3 is an explanatory diagram for explaining the internal configuration of the rocking device 100. In Figure 3, for convenience of illustration, the outline of the configuration covered by the cover 20 is shown in a schematic diagram, and the outline of the configuration not covered by the cover 20 is shown in a top view. Note that in Figure 3, the cover 20 is shown with a dashed line, and the illustration of the wiring is omitted. The rocking device 100 is used to rock a doll in nursing practice or medical practice, etc. The doll is not particularly limited, but it is preferably a doll modeled after a child, and more preferably a doll modeled after an infant. As shown in Figures 1 to 3, the rocking device 100 in this embodiment comprises a base 10, a cover 20, a mounting section 30, a drive section 40, an adjustment section 50, a remote control section 60, an audio output section 70, and a power supply section 80.

[0017] The base 10 is formed from a plate-shaped member and constitutes the bottom of the rocking device 100. Other components of the rocking device 100 are arranged on the upper surface of the base 10. The cover 20 is attached to the upper surface of the base 10 and houses the crank mechanism unit 42, adjustment unit 50, microcontroller 62 of the remote control unit 60, audio output unit 70, etc., which will be described later. The cover 20 has a through hole 24 that penetrates through the thickness of the plate, and the speaker 76 is exposed through the through hole 24.

[0018] The mounting section 30 is positioned without being covered by the cover 20. The doll's head rests on the upper part 32 in the vertical direction of the mounting section 30. In Figure 1, the mounting section 30 is hatched for ease of understanding. In this embodiment, the mounting section 30 has an external shape that is approximately a rectangular prism extending along the horizontal direction D1. The horizontal direction D1 is approximately perpendicular to the vertical direction and the direction of the doll's height. In this disclosure, "direction of the doll's height" corresponds to the direction extending from the doll's head to its feet and coincides with the direction in which the doll's neck extends. Also, in this disclosure, "approximately perpendicular directions" means directions that intersect within an angle range of 70° to 110°, not limited to directions that intersect at 90°. The detailed configuration of the mounting section 30 will be described later.

[0019] The drive unit 40 shown in Figure 3 includes a crank mechanism unit 42 and a rail 48. The crank mechanism unit 42 includes a motor 44 and a transmission unit 46. The motor 44 is housed inside the cover 20. In this embodiment, the motor 44 is electrically connected to the power supply unit 80 via the PWM control unit 52 of the adjustment unit 50 and the microcontroller 62 of the remote control unit 60. The power supply unit 80 in this embodiment includes an AC adapter, but may also include a battery. The motor 44 rotates using power supplied from the power supply unit 80. The transmission unit 46 is connected to the mounting unit 30. More specifically, the transmission unit 46 is connected to the end of the mounting unit 30 in the horizontal direction D1. The crank mechanism unit 42 converts the rotational motion of the motor 44 into the reciprocating motion of the transmission unit 46. The rail 48 is arranged along the upper surface of the base 10 and is formed to extend along the horizontal direction D1. In this embodiment, the rail 48 includes a plurality of bearings arranged in a horizontal direction D1. The rail 48 has a dimension along the horizontal direction D1 that is greater than that of the mounting portion 30, and the mounting portion 30 is located above it.

[0020] The placement unit 30 slides in the horizontal direction D1 on the upper part of the rail 48 when the reciprocating motion of the transmission unit 46 is transmitted. In this way, the drive unit 40 reciprocates the placement unit 30 along the horizontal direction D1. Since the drive unit 40 of the present embodiment slides the placement unit 30 in the horizontal direction D1 on the rail 48, the placement unit 30 can be reciprocated smoothly.

[0021] The adjustment unit 50 adjusts the frequency of the reciprocating motion of the placement unit 30. The adjustment unit 50 is electrically connected to the motor 44 of the crank mechanism unit 42, and adjusts the frequency of the reciprocating motion of the placement unit 30 by controlling the rotation speed of the motor 44. In the present embodiment, the adjustment unit 50 has a PWM control unit 52 and an operation unit 54. In the present embodiment, the PWM control unit 52 is attached to the inner surface 22 of the cover 20 and is electrically connected to the microcomputer 62 of the remote operation unit 60. In the present embodiment, the operation unit 54 is exposed outside the cover 20 and is configured to be rotatable about an axis orthogonal to the plate thickness of the side surface of the cover 20. The user of the rocking device 100 can adjust the frequency by rotating the operation unit 54 around the axis. In the present embodiment, the operation unit 54 also serves as the power switch of the rocking device 100, but a power switch may be provided separately.

[0022] The remote operation unit 60 adjusts the frequency of the reciprocating motion of the placement unit 30 by remote operation. The remote operation unit 60 has a microcomputer 62 and a remote controller 64. In the present embodiment, the microcomputer 62 is attached to the inner surface 22 of the cover 20 and is electrically connected to the adjustment unit 50. The remote controller 64 is configured to be capable of wireless communication with the microcomputer 62. The remote controller 64 of the present embodiment has buttons, sliders, etc. not shown, and controls the adjustment unit 50 via wireless communication with the microcomputer 62. Note that the remote controller 64 may be constituted by a mobile terminal such as a smartphone or a tablet.

[0023] The audio output unit 70 outputs the sound of an infant crying. In this embodiment, the audio output unit 70 is attached to the inner surface 22 of the cover 20. The audio output unit 70 includes a reading unit 72, a microcontroller 74, and a speaker 76. The reading unit 72 is formed to include an interface such as an SD card slot or a USB port, and reads audio data stored on an SD card, USB, etc. The reading unit 72 may also read audio data via wireless communication or the like. The microcontroller 74 causes the audio data read by the reading unit 72 to be output from the speaker 76. The speaker 76 is positioned in a location corresponding to a through hole 24 formed in the cover 20.

[0024] B. Mounting section configuration As shown in Figure 2, in this embodiment, the upper part 32 of the mounting section 30 is formed such that the central part 34 in the horizontal direction D1 is recessed vertically downward compared to the ends 36 in the horizontal direction D1. More specifically, the upper part 32 of the mounting section 30 is formed with a roughly arc-shaped recess when viewed from the front. This configuration allows the doll's head to be stably placed on the upper part 32 of the mounting section 30, thereby preventing the doll from shifting away from the mounting section 30 due to shaking. The upper part 32 of the mounting section 30 may be formed with a recess of any shape instead of a roughly arc shape when viewed from the front. The dimensions of the mounting section 30 along the horizontal direction D1 should be long enough to stably place the head of a doll modeled after an infant on the upper part 32 and prevent it from slipping off during shaking. Furthermore, the thickness of the mounting section 30 along the vertical direction at the central part 34 should be high enough so that when the head of a doll modeled after an infant is placed on the upper part 32, the doll's head does not touch the base 10.

[0025] In this embodiment, the mounting portion 30 is made of a resin material. However, the mounting portion 30 may be made of any material other than resin, such as metal. Also, in this embodiment, the surface of the upper part 32 of the mounting portion 30 has a higher coefficient of dynamic friction with respect to the silicone resin than the bottom surface of the mounting portion 30. More specifically, the surface of the upper part 32 of the mounting portion 30 is formed to increase friction, for example by anti-slip processing, while the bottom surface of the mounting portion 30 is formed to decrease friction, for example by Teflon® coating. The increased friction on the surface of the upper part 32 of the mounting portion 30 allows the doll's neck to be placed on the upper part 32 of the mounting portion 30 more stably, thereby further suppressing the doll from shifting away from the mounting portion 30 due to shaking. Furthermore, the decreased friction on the bottom surface of the mounting portion 30 allows the mounting portion 30 to move back and forth smoothly, resulting in the doll being able to be shaken smoothly.

[0026] C. Operation of the rocking device Figure 4 is an explanatory diagram showing an example of the state in which the rocking device 100 is used. In Figure 4, a doll 90 is shown placed on the mounting part 30 of the rocking device 100. More specifically, the doll 90 is placed on the upper part 32 of the mounting part 30, with the area including its neck resting on it, so that its height direction is approximately perpendicular to the horizontal direction D1. As a result, the doll 90 is in a lying position along the surface of the base 10, i.e., approximately horizontal plane. In the example shown in Figure 4, the doll 90 is placed in a supine position, but the doll 90 may be placed not only in a supine position, but also in a side position or a prone position. In Figure 4, a doll 90 modeled after an infant is shown as an example of a doll 90 used. The doll 90 may be made of any resin material such as silicone resin.

[0027] Users of the rocking device 100 can operate the drive unit 40 to move the mounting unit 30 back and forth by operating the operation unit 54 of the adjustment unit 50 or the remote controller 64 of the remote control unit 60, and can also adjust the frequency of the reciprocating motion. As the mounting unit 30 reciprocates along the horizontal direction D1, the doll 90 rocks along the horizontal direction D1. The higher the frequency of the reciprocating motion of the mounting unit 30, the more violently the doll 90 rocks. From the viewpoint of reproducing the movements of a living infant in a more realistic manner, the frequency of the reciprocating motion of the mounting unit 30 is preferably between 1 Hz and 6 Hz, and more preferably between 2 Hz and 4 Hz. The frequency of this reciprocating motion is not limited to being kept constant, but may be changed randomly or periodically. Such frequency control can be realized, for example, by the microcontroller 62 of the remote control unit 60. Furthermore, the amplitude of the swing during the reciprocating motion of the mounting portion 30 is preferably 0.8 cm to 3.4 cm, and more preferably 1.2 cm to 2.6 cm, from the viewpoint of reproducing the movements of a living infant in a more realistic manner. In this disclosure, "swing amplitude" means the maximum displacement of the mounting portion 30 at a certain point, and corresponds to the displacement of the mounting portion 30 when it is located at the furthest end and furthest end in the horizontal direction D1 during the reciprocating motion.

[0028] In this embodiment, the sound output unit 70 outputs the sound of an infant crying in conjunction with the reciprocating motion of the mounting unit 30. More specifically, when the power to the rocking device 100 is turned ON and the mounting unit 30 moves back and forth, the sound output unit 70 outputs sound data of an infant crying. Furthermore, the sound output unit 70 outputs the sound of an infant crying more loudly as the frequency of the reciprocating motion of the mounting unit 30 increases. With this configuration, the state of a living infant can be reproduced more accurately, and as a result, practical exercises using dolls can be conducted in a more realistic state.

[0029] As described above, the rocking device 100 of this embodiment includes a mounting section 30 on which the head of the mannequin 90 rests in the vertical upper section 32, and a drive unit 40 that reciprocates the mounting section 30 along a horizontal direction D1 that is substantially perpendicular to the vertical direction and the height direction of the mannequin 90. Therefore, the mannequin 90 can be rocked with a simple mechanism. In actual nursing and medical settings, it is expected that patients, especially children including infants, may move or struggle in response to various procedures. However, if nursing practice or medical practice is conducted using a stationary mannequin 90 without using the rocking device 100 of this application, various procedures will be easier than they actually are, and the practice cannot be conducted in a realistic manner. In contrast, with the rocking device 100 of this application, the mannequin 90 can be rocked, so practice using the mannequin 90 can be conducted in a realistic manner with a simple mechanism.

[0030] Furthermore, with the rocking device 100 of this embodiment, since the head of the doll 90 is placed on the upper part 32 of the mounting section 30, it is possible to suppress the doll 90 from shifting relative to the mounting section 30. Also, with the rocking device 100 of this embodiment, since it is possible to rock a doll 90 that does not have a movable mechanism inside, it is possible to suppress the complexity of the doll 90's structure, and as a result, it is possible to suppress an increase in the cost required to manufacture the doll 90, and thus suppress an increase in the cost of the doll 90 used in practical training. In addition, with the rocking device 100 of this embodiment, since it is possible to rock a doll 90 that does not have a movable mechanism inside, it is possible to conduct realistic practical training using existing dolls 90.

[0031] Furthermore, the rocking device 100 of this embodiment includes an adjustment unit 50 that can adjust the frequency of the reciprocating motion of the mounting unit 30. For example, the degree of rocking of the doll 90 can be adjusted by changing the frequency according to the content of the practical exercise. As a result, the movements of a living infant can be reproduced more accurately, allowing practical exercises using the doll 90 to be conducted in a more realistic state. In addition, the rocking device 100 of this embodiment includes a remote control unit 60 that can remotely adjust the frequency of the reciprocating motion of the mounting unit 30. As a result, the degree of rocking of the doll 90 can be easily adjusted, allowing practical exercises using the doll 90 to be conducted in a more realistic state and improving convenience.

[0032] D. Variations The configuration of the rocking device 100 in the above embodiment is merely an example and can be modified in various ways. For example, in the above embodiment, the mounting portion 30 had a roughly rectangular prism shape extending along the horizontal direction D1, but it is not limited to a roughly rectangular prism and may have any shape. Also, for example, in the above embodiment, the upper part 32 of the mounting portion 30 was formed with the central part 34 in the horizontal direction D1 recessed vertically downward than both ends 36, but instead of the recess, a material such as low-rebound urethane foam that deforms according to the shape of the doll 90 may be attached, and the recess may be omitted. Also, for example, the drive unit 40 is not limited to the configuration of the above embodiment and may have any configuration that can reciprocate the mounting portion 30 along the horizontal direction D1. Also, for example, the rocking device 100 may omit the base 10, and the cover 20 may be omitted. Also, for example, the rocking device 100 may omit the adjustment unit 50. Also, for example, the rocking device 100 may omit the remote control unit 60. Furthermore, for example, the rocking device 100 may omit the audio output unit 70. Also, for example, the mounting unit 30 may be configured as a replaceable attachment. More specifically, for example, the rocking device 100 may be equipped with a plurality of mounting units 30 having different sizes and shapes, and the user of the rocking device 100 may be able to change the mounting units 30 according to the size of the doll 90, the direction in which it is laid down, etc. With such a configuration, since the mounting unit 30 can be selected according to the size of the doll 90, etc., the doll 90 can be prevented from shifting away from the mounting unit 30 due to rocking. In other words, by selecting the shape and size of the mounting unit 30, the doll 90 can be rocked appropriately even if the size or type of the doll 90 changes, thus realizing a highly versatile rocking device 100.

[0033] This disclosure is not limited to the embodiments described above, and can be implemented in various configurations without departing from its spirit. For example, the technical features in each embodiment corresponding to the technical features in each form described in the summary of the invention can be replaced or combined as appropriate in order to solve some or all of the above-described problems, or to achieve some or all of the above-described effects. Furthermore, if a technical feature is not described as essential in this specification, it can be deleted as appropriate. [Explanation of symbols]
