[0010] (Embodiment 1) Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0011] FIG. 1 is an explanatory diagram showing a display system. The display system includes a cover unit 1, a sensor 3, an upper limb support 4, and a control device 5. The control device 5 includes a display unit 2, which will be described later. When the sensor 3 detects an affected area of ​​a patient, the display system displays content on the display unit 2. The affected area of ​​the patient is, for example, the patient's arm or leg. In this embodiment, the affected area is described as the arm.

[0012] The control device 5 is, for example, a personal computer (hereinafter referred to as a computer) or a tablet. In this embodiment, the control device 5 will be described as a tablet 5. The display unit 2 is connected to the tablet 5. The patient is, for example, a child or an adult. In this embodiment, the patient will be described as a child.

[0013] The cover 1 is, for example, a housing, and is formed by five rectangular plates: a side portion 11, a side portion 12, a rear portion 13, a floor portion 14, and a top portion 15. The floor portion 14 is located on the lower side in FIG. 1, and the top portion 15 is located on the upper side in FIG. 1. The side portion 11 and the side portion 12 are located opposite each other. The edges of the rear portion 13 are in contact with the side portion 11, the side portion 12, the floor portion 14, and the top portion 15, respectively. A first opening 11a is formed in the side portion 11. The first opening 11a is, for example, circular. The diameter of the first opening 11a is, for example, large enough that a child cannot see their arm inserted into the first opening 11a. A second opening 16a for puncturing is formed in the surface adjacent to the side portion 11 (the surface on the near side in FIG. 1). The upper limb support 4 is, for example, in the shape of a rectangular prism or an elliptical prism. The upper limb support 4 is placed on the floor surface 14 below the first opening 11a. The upper limb support 4 is large enough for the child to place their arm inserted through the first opening 11a. The sensor 3 is, for example, an infrared sensor. The sensor 3 is, for example, placed on the rear surface 13 side of the floor surface 14 near the first opening 11a. The tablet 5 is disposed above the top surface 15. The tablet 5 includes a display unit 2. The display unit 2 is, for example, a display panel such as a liquid crystal panel or an organic EL (Electro-Luminescence) panel. The display surface of the display unit 2 faces, for example, diagonally upward toward the side surface 11.

[0014] The cover 1 may be formed of four rectangular plates, namely, the side portion 11, the side portion 12, the rear portion 13, and the top portion 15, excluding the floor portion 14. In its simplest configuration, the cover 1 may have a configuration that prevents the patient from seeing the arm. A cover may be arranged around the circumference of the first opening 11a to prevent children from seeing inside the cover 1. The second opening 16a may be formed in a part of the surface adjacent to the side portion 11 (the surface on the front side in FIG. 1 ). The second opening 16a may be formed in the rear portion 13. The sensor 3 may be an ultrasonic sensor, an optical position sensor, or a camera. A lighting device (not shown) may be arranged on the inner surface of the top portion 15. A child using the display system can remove the tablet 5 arranged on the upper side of the top portion 15. The child can freely carry the removed tablet 5. The tablet 5 may be embedded, for example, in a recess (not shown) on the upper side of the side portion 11. The tablet 5 may be embedded in any location in the cover 1. The display system may use a projector (not shown) or the like instead of the display 2.

[0015] 2 is a block diagram showing the hardware configuration of the tablet. The tablet 5 includes a control unit 51, a storage unit 52, a communication unit 53, a display unit 2, and a reading unit 54. The above-mentioned units are interconnected via a bus. The sensor 3 is connected to the tablet 5 via short-range wireless communication such as Bluetooth (registered trademark) or Wi-Fi (registered trademark). The control unit 51 is configured using one or more processors such as a CPU (Central Processing Unit), an MPU (Micro-Processing Unit), or a GPU (Graphics Processing Unit). The control unit 51 executes various information processing operations performed by the tablet 5 by appropriately executing a control program 52P (program product) stored in the storage unit 52.

[0016] The storage unit 52 includes a RAM (Random Access Memory) or a ROM (Read Only Memory). The storage unit 52 stores in advance a control program 52P executed by the control unit 51 and various data required for executing the control program 52P. The storage unit 52 also stores content to be displayed on the display unit 2. The content includes, for example, video, images, audio data, and AR (Augmented Reality). The storage unit 52 also temporarily stores data generated when the control unit 51 executes the control program 52P. The communication unit 53 transmits and receives information to and from an external computer (not shown). The control unit 51 uses the communication unit 53 to obtain the latest content from the external computer.

[0017] The display unit 2 displays content for children based on instructions from the control unit 51 that has received notification from the sensor 3. The sensor 3 detects infrared rays emitted from the child's arm when the child inserts the arm into the first opening 11a. The sensor 3 includes a sensor element for measuring the detected infrared rays. The sensor 3 notifies the control unit 51 whether or not infrared rays have been detected.

[0018] The reading unit 54 reads information stored in a portable storage medium 2a, such as a CD (Compact Disc)-ROM, a DVD (Digital Versatile Disc)-ROM, a USB (Universal Serial Bus) memory, or an SD (Secure Digital) card. The control program 52P and various data stored in the storage unit 52 may be stored in the storage unit 52 by the control unit 51 reading them from the portable storage medium 2a via the reading unit 54. Alternatively, the control program 52P and various data stored in the storage unit 52 may be stored in the storage unit 52 by the control unit 51 downloading them from an external device (not shown) via the communication unit 53.

[0019] In the first embodiment, a method for displaying content on the display unit when the display system detects infrared rays emitted from a child's arm using a sensor will be described. The control unit 51 periodically acquires the latest content from an external computer or the like via the communication device 3. The control unit 51 stores the acquired latest content in the storage unit 52.

[0020] A child using the display system inserts their arm into the first opening 11a. The sensor 3 detects infrared rays emitted by the child's arm. When the sensor 3 detects the infrared rays, the control unit 51 reads out content to be displayed on the display unit 2 from the memory unit 52. The control unit 51 displays the read content on the display unit 2. A medical professional using the display system can perform the puncture procedure at the second opening 16a while the child is viewing the content displayed on the display unit 2.

[0021] In the first embodiment, the tablet 5 is placed on the top surface 15, but this is not limiting. A medical professional or a child can freely carry the tablet 5. The child can view the content displayed on the display unit 2 from any position.

[0022] In the first embodiment, an example in which content is displayed on the display unit 2 has been described, but the present invention is not limited to this. The display system can display content at any location (for example, the side surface unit 11) via a projector (not shown). In this case, the tablet 5 transmits data for displaying the content to the projector using short-range wireless communication such as Bluetooth (registered trademark) or Wi-Fi (registered trademark). The projector displays the content at any location using the data received from the tablet 5. Children can view the content without using the display unit 2.

[0023] 3 is a flowchart showing an example of a processing procedure of the display system according to the first embodiment. The control unit 51 periodically acquires the latest content from an external computer or the like via the communication unit 53 (step S101). The control unit 51 stores the acquired latest content in the storage unit 52 (step S102). The sensor 3 detects infrared rays emitted from the child's arm inserted into the first opening 11a (step S103). When the sensor 3 detects infrared rays, the control unit 51 reads out content to be displayed on the display unit 2 from the storage unit 52 (step S104). The control unit 51 displays the read out content on the display unit 2 (step S105).

[0024] According to this embodiment, the display system can display content on the display unit 2 when the sensor 3 detects infrared rays emitted by the child's arm.

[0025] According to this embodiment, a medical professional using the display system can perform the puncture procedure while the child is watching the content.

[0026] (Embodiment 2) In the second embodiment, a method is described in which the display system switches the content displayed on the display unit depending on whether or not a child is present.

[0027] 4 is an explanatory diagram showing a display system according to a second embodiment. The tablet 5 includes a camera 6. The camera 6 captures an image of an area on the side surface 11 of the display system (hereinafter referred to as an imaging area). The tablet 5 and the camera 6 may be separate. In this case, the camera 6 is disposed adjacent to the tablet 5 above the top surface 15.

[0028] FIG. 5 is a block diagram showing the hardware configuration of a tablet according to the second embodiment. The storage unit 52 stores first and second contents. The first contents are, for example, explanatory images for children who use the display system. The second contents are, for example, images that distract children from the puncture procedure. The tablet 5 also includes a camera 6. The camera 6 is an imaging device such as a CCD (Charge Coupled Device) camera or a CMOS (Complementary Metal Oxide Semiconductor) camera. The camera 6 captures images of the imaging range (hereinafter referred to as captured images) at regular time intervals (e.g., 10 seconds).

[0029] The control unit 51 reads out the first content from the storage unit 52. The control unit 51 displays the read-out first content on the display unit 2. FIG. 6 is an explanatory diagram showing an example of the first content. The first content includes a message and an image for explaining how to use the display system. In the example of FIG. 6, a message saying "Sit in front and insert your arms into the holes" and an image of a child inserting their arms into the first opening 11a are displayed. The control unit 51 acquires captured images at regular time intervals using the camera 6. The control unit 51 determines whether a person is captured in the acquired captured images. To determine whether a person is captured in the captured images, for example, a known machine learning model or pattern matching may be used. If the control unit 51 determines that a person is not captured in the captured images, it continues to display the first content on the display unit 2. If the control unit 51 determines that a person is captured in the captured images, it reads out the second content from the storage unit 52. The control unit 51 displays the read-out second content on the display unit 2.

[0030] FIG. 7 is an explanatory diagram showing an example of the second content. The second content includes a message and an image to distract the child. In the example of FIG. 7, a message "Find the Difference (3 places)" and two images used for finding the difference are displayed. The control unit 51 may switch the displayed second content to another second content after a predetermined time has elapsed (for example, 60 seconds).

[0031] The control unit 51 uses the camera 6 to acquire a captured image again. The control unit 51 determines whether or not a person is captured in the acquired captured image. If the control unit 51 determines that a person is captured in the captured image, it continues to display the second content on the display unit 2. Furthermore, if the control unit 51 determines that a person is captured in the captured image, it may display another second content on the display unit 2 after a certain period of time (for example, 10 seconds) has elapsed. If the control unit 51 determines that a person is not captured in the captured image, it reads out the first content from the storage unit 52. The control unit 51 displays the read out first content on the display unit 2.

[0032] (Variation) The display system of the second embodiment may include a sensor 3, as in the first embodiment. In this case, the sensor 3 detects infrared rays emitted by the child's arm. The control unit 51 continues to display the second content on the display unit 2 when the sensor 3 does not detect infrared rays. The control unit 51 reads out the third content from the storage unit 52 when the sensor 3 detects infrared rays. The third content is content intended to distract the child from the puncture procedure, similar to the second content. The control unit 51 displays the read out third content on the display unit 2.

[0033] FIG. 8 is a flowchart showing an example of a processing procedure of the display system according to the second embodiment. In the flowchart shown in FIG. 8, steps S103 to S105 in the processing shown in FIG. 3 are replaced with steps S301 to S310. Descriptions of steps similar to those in FIG. 3 will be omitted. The control unit 51 reads out the first content from the storage unit 52 (step S301). The control unit 51 displays the read out first content on the display unit 2 (step S302). The control unit 51 acquires captured images at regular time intervals using the camera 6 (step S303). The control unit 51 determines whether or not a person is captured in the acquired captured images (step S304). If the control unit 51 determines that a person is not captured in the captured images (step S304: NO), the control unit 51 returns the process to step S302. If the control unit 51 determines that a person is captured in the captured images (step S304: YES), the control unit 51 reads out the second content from the storage unit 52 (step S305). The control unit 51 reads out the second content. on the display unit 2 (step S306). The control unit 51 reacquires the captured image using the camera 6 (step S307). The control unit 51 determines whether or not a person is captured in the captured image (step S308). If the control unit 51 determines that a person is captured in the captured image (step S308: YES), the control unit 51 returns the process to step S306. If the control unit 51 determines that a person is not captured in the captured image (step S308: NO), the control unit 51 reads out the first content from the storage unit 52 (step S309). The control unit 51 displays the read out first content on the display unit 2 (step S310).

[0034] According to this embodiment, the display system can switch the content displayed on the display unit 2 depending on whether or not a child is using the display system.

[0035] According to this embodiment, the display system can explain to children how to use the display system by displaying the first content.

[0036] According to this embodiment, the display system can distract the child from the puncture procedure by displaying the second content.

[0037] (Embodiment 3) In the third embodiment, a method for starting the blood vessel retrieval device when the display system detects a child's arm using a sensor will be described.

[0038] 9 is an explanatory diagram showing a display system according to embodiment 3. The display system includes a blood vessel searching device 7. The blood vessel searching device 7 is disposed on the inner surface of the top surface 15 at a position facing the upper limb support 4. The blood vessel searching device 7 detects infrared rays irradiated onto the child's arm using an infrared reflection method, and projects a blood vessel image onto the child's arm based on the detected infrared rays.

[0039] FIG. 10 is a block diagram showing the hardware configuration of the blood vessel searching device. The blood vessel searching device 7 includes a control unit 71, a storage unit 72, a communication unit 73, a light-emitting unit 74, a light-receiving unit 75, a processing unit 76, and a projection unit 77. The above-mentioned units are interconnected via a bus. The control unit 71 is configured using one or more processors such as a CPU, an MPU, or a GPU. The control unit 71 executes various information processing performed by the blood vessel searching device 7 by appropriately executing a control program 72P (program product) stored in the storage unit 72. The storage unit 72 includes a RAM or a ROM. The storage unit 72 pre-stores the control program 72P executed by the control unit 71 and various data required for executing the control program 72P. The storage unit 72 also temporarily stores data generated when the control unit 71 executes the control program 72P. The communication unit 73 transmits and receives information to and from the tablet 5.

[0040] The light-emitting unit 74 is, for example, a light-emitting diode. The light-emitting unit 74 irradiates the child's arm with infrared light of 700 nm to 2500 nm. The light-receiving unit 75 has a light-receiving element and receives the infrared light reflected from the child's arm. The processing unit 76 generates an image of the blood vessels in the child's arm from the received infrared light, based on the fact that infrared light is easily absorbed by blood. The projection unit 77 projects the generated image of the blood vessels onto the child's arm.

[0041] The sensor 3 detects infrared rays emitted by the child's arm in the same procedure as in embodiment 1. When the sensor 3 detects infrared rays, the control unit 51 transmits a notification to the blood vessel searching device 7 to start the blood vessel searching device 7 (hereinafter referred to as start notification).

[0042] The control unit 71 receives the activation notification sent from the tablet 5. The control unit 71 uses the light emitting unit 74 to irradiate the child's arm with infrared rays. The control unit 71 uses the light receiving unit 75 to receive the infrared rays reflected from the child's arm. The control unit 71 uses the processing unit 76 to The control unit 71 uses the projection unit 77 to project the generated blood vessel image onto the child's arm.

[0043] Fig. 11 is a flowchart showing an example of a processing procedure of the display system according to embodiment 3. In the flowchart shown in Fig. 11, steps S104 to S105 in the processing shown in Fig. 3 are replaced with steps S401 to S406. Explanation of the same steps as in Fig. 3 will be omitted. When the sensor 3 detects infrared rays, the control unit 51 transmits a notification to the blood vessel searching device 7 to start the blood vessel searching device 7 (hereinafter referred to as start notification) (step S401).

[0044] The control unit 71 receives the startup notification sent from the tablet 5 (step S402). The control unit 71 uses the light-emitting unit 74 to irradiate the child's arm with infrared rays (step S403). The control unit 71 uses the light-receiving unit 75 to receive the infrared rays reflected from the child's arm (step S404). The control unit 71 uses the processing unit 76 to generate a blood vessel image of the child's arm from the received infrared rays (step S405). The control unit 71 uses the projection unit 77 to project the generated blood vessel image onto the child's arm (step S406).

[0045] According to this embodiment, the display system can start the blood vessel retrieval device when the sensor detects a child's arm.

[0046] According to this embodiment, the display system can support medical personnel in performing puncture by projecting the generated blood vessel image onto a child's arm.

[0047] According to this embodiment, the display system can improve the success rate of puncture by medical staff by projecting the generated blood vessel image onto the child's arm.

[0048] (Embodiment 4) In the fourth embodiment, an example will be described in which a display system includes a movement mechanism for moving the position of the display unit.
