Unexamined-Japanese-Patent No. 2015-19679

  By the way, in a scene where a plurality of diagnostic devices are connected to the HMD, an alarm indicating that the diagnostic value is an abnormal value may be output from some of the diagnostic devices. In such a case, the priority of the diagnostic information required by the user may differ depending on the status of the diagnostic information of the other diagnostic device and the role of the user in the medical field. However, in the above-described technology, it is difficult to automatically output diagnostic information corresponding to the priority for each user to the HMD in accordance with the situation that changes each time.

  An object of the present invention is to provide an information output device capable of outputting and controlling device information with a priority according to the situation of the site which changes from time to time.

An information output apparatus according to the present invention is an information output apparatus that outputs device information output from each of a plurality of measuring devices to an information output unit, and identification information for acquiring identification information for identifying the information output unit. Acquisition means, device information acquisition means for acquiring the device information, device state acquisition means for acquiring the device state which is the state of each of the plurality of measuring devices based on the device information, and output to the information output unit that the a priority of the device information, the first priority is predefined for each of the plurality of measuring devices, a first priority setting means for setting in accordance with the identification information, the device state obtaining means Second priority setting means for setting the second priority, which is the priority changing according to the device state obtained by the setting, for each of the plurality of measuring devices, and the first priority setting means The third priority which is the priority for each device state according to the identification information is determined based on the first priority and the second priority set by the second priority setting means. A priority determining unit; and an output control unit configured to cause the information output unit corresponding to the identification information to output the device information according to the device state according to the third priority determined by the priority determining unit. Prepare.

  According to the information output apparatus of the present invention, the first priority setting means sets the first priority which is the priority of the device information of each of the plurality of measuring devices according to the identification information. The second priority setting means sets, for each measuring device, a second priority which is a priority according to the device state which is the state of the measuring device. Then, in accordance with the first priority and the second priority, the third priority for each device state according to the identification information indicating each information output unit is determined. Therefore, for example, when an alarm indicating that the measurement value is an abnormal value is output from some of the plurality of measuring devices, the device information for each of the plurality of measuring devices according to the identification information Necessary information is output to the information output unit of the user according to the identification information in consideration of the first priority of the second information and the second priority according to the device state of the measuring device. Therefore, the information output device according to the present invention can control the output of the device information with the priority according to the situation of the site which changes every time.

  The output control means causes the information output unit to output, to the information output unit, a recommended image on which images relating to higher-level device information, which is a plurality of pieces of device information determined to be higher than the third priority, are displayed selectable. When the selection instruction corresponding to the image is received, the device information corresponding to the received selection instruction may be output to the information output unit.

  Depending on the situation of the user, other device information different from the device information according to the third priority may be required. In the information output device, a recommended image related to higher-level device information determined to be higher than the third priority is output to the information output unit, and device information corresponding to a selection instruction corresponding to the recommended image is output to the information output unit. Therefore, the user can select necessary device information, and the convenience of the information output apparatus is improved.

  The output control means may suppress and output an information amount of device information whose third priority is lower than the upper device information to an information amount smaller than the upper device information.

  When many pieces of device information are output from the information output unit, depending on the situation of the user, it may not be possible to process all of the information output to the information output unit. The amount of information that can be output by the information output unit is limited. Since the information output apparatus suppresses and outputs the amount of information of the device information whose third priority is lower than the upper device information to a smaller amount of information than the upper device information, the device information suitable for the user's situation is output to the user Can be provided.

  The information output device sets device information amount setting means for setting an amount of device information indicating the amount of information of the device information for each of the plurality of measuring devices, and the user processes the device information output from the information output unit Processing capability setting unit according to the identification information, the device information amount set by the device information amount setting unit, and the processing capability set by the processing capability setting unit The apparatus may further include a calculation unit that calculates the processing load amount of each of the plurality of measurement devices according to the identification information. The output control means may output the device information to an information output unit corresponding to the identification information according to the third priority and the processing load amount.

  Depending on the information output capability of the information output unit, the information output device may have difficulty outputting the device information according to the third priority to the information output unit as it is. In addition, the processing capability of each user with respect to the device information output to the information output unit may be different. Since the information output device calculates the processing load amount according to the device information amount and the processing capacity of the user, the calculated processing load amount corresponds to the third priority, the information output capability of the information output unit and the user processing It can output device information suitable for the capability.

  The output control means may output each of the pieces of device information having the same third priority according to the device information at different output timings in arbitrary order.

  For example, when a plurality of pieces of device information include a plurality of pieces of voice information, even if a plurality of pieces of device information are output at one time from the information output unit, the user may not be able to grasp information required. Since the output control means can output the device information with the same third priority at different output timings according to the device information, the convenience of the information output apparatus is improved.

  The information output apparatus receives an update request for updating at least one of the first priority and the second priority, and the update request received by the update reception unit has specific characteristics. The update judging means for judging whether the information is information based on the identification information, and the update request in response to the update request when it is judged by the update judgment means that the update request is identification information having the specific characteristic. The first priority and the second priority are updated, and when it is determined that the update request is not identification information having the specific characteristic, the first priority and the second priority according to the update request. And updating means that does not update the

  In this case, the first priority is updated only if the update request is based on identification information having a specific characteristic. As the user of the information output unit corresponding to the identification information having the specific characteristic determines that the first priority and the second priority should be updated, the device information of the third priority according to the update request is information Since it is output to the output unit, other users can easily understand the necessary information.

  The identification information acquisition unit refers to a transition order storage unit that stores a transition order in which the specific characteristic transitions in the plurality of identification information corresponding to the plurality of information output units, and the identification information obtaining unit determines the highest identification information in the transition order. The characteristic of the corresponding information output unit may be set to the specific characteristic.

  For example, a user of an information output unit corresponding to identification information having a specific characteristic may leave the place. Even in such a case, since the specific characteristics are transitioned according to the transition order in the plurality of identification information, device information corresponding to the situation of the site where the information output device is used is output from the information output unit.

  The information output apparatus may include update inhibiting means for inhibiting update of part or all of at least one of the first priority and the second priority by the updating means.

  In this case, the information output device can prevent, for example, the update unit from updating up to the area that should not be updated among the first priority and the second priority.

Image light indicating an image displayed on the image display unit 22 is incident on the lens unit from the right side, and is emitted toward the half mirror 4 from the left side. The half mirror 4 reflects the image light emitted from the lens unit to the rear. In the state where the HMD 10 is worn by the user, the image light enters the eyeball of the user's left eye. In addition, the half mirror 4 transmits light from an external real image toward the user's left eye. The HMD 10 allows the user to visually recognize a scene in a state in which the image displayed on the image display unit 22 is superimposed on a real image (for example, a landscape of the outside world) within the field of view of the user.

  The image display unit 22 may be a liquid crystal display, an organic EL (Organic Electro-luminescence) display, or the like. The image display unit 22 may be a retinal scanning projector that projects light scanned two-dimensionally on the user's retina. The half mirror 4 may be made of glass. Instead of the half mirror 4, an optical path deflection member such as a prism or a diffraction grating that deflects the optical path by the action of refraction, total internal reflection or diffraction may be used. Instead of the half mirror 4, a total reflection mirror may be used.

  The mounting tool 8 is configured to hold the HD 20 on the head of the user. The mounting tool 8 is formed of, for example, a flexible resin, or a metal material such as stainless steel. The mounting tool 8 has a first portion 8A and a pair of second portions 8B. Each of the first portion 8A and the pair of second portions 8B is a curved elongated plate-like member. The mounting tool 8 is mounted on the head of the user with the first portion 8A on the forehead of the user and the pair of second portions 8B on the right and left head of the user.

  The connector 9 is a configuration for connecting the mounting tool 8 and the HD 20. The connector 9 is a slightly curved rod-like member. The upper end portion of the connector 9 is connected to the mounting tool 8. The lower end of the connector 9 is connected to the HD 20. The connector 9 holds the HD 20 at a position separated from the mounting tool 8. The connector 9 can arrange the half mirror 4 of the housing 20A in front of the left eye of the user in a state where the mounting tool 8 is attached to the user. In this case, the user can visually recognize the image displayed on the image display unit 22 through the half mirror 4.

  The CB 30 controls the HD 20. The CB 30 is connected to the HD 20 via the harness 7. Note that the CB 30 and the HD 20 may perform wireless communication via wireless communication without using the harness 7. The CB 30 is attached to a position different from the HD 20 (for example, the user's waist belt, arm, etc.). However, the CB 30 may be configured integrally with the HD 20 or the attachment 8. The CB 30 includes an operation unit 37 including a power switch and operation buttons (not shown). Various settings in the HD 20, various operations at the time of use, power on / off operations, and the like are input to the operation unit 37.

  Next, the electrical configuration of the HMD 10 will be described. First, the electrical configuration of the CB 30 will be described. The CB 30 includes a CPU 31 that controls the entire CB 30. The CPU 31 is electrically connected to the RAM 32, the flash memory 33, the input unit 34, the wireless communication unit 36, the operation unit 37, and the connection controller 35. The RAM 32 temporarily stores various data such as calculation results obtained by calculation processing by the CPU 31.

  In addition, the HMD 10 may download and install various programs and an OS from a server for downloading a program via wireless communication. For example, the various programs and the OS may be transmitted from the server to the HMD 10 as a computer-readable temporary storage medium (for example, a transmission signal). The flash memory 33 is an example of a non-temporary storage medium. The non-temporary storage medium may be any storage medium that can store information regardless of the storage period of the information. Non-transitory storage media may not include temporary storage media (eg, signals to be transmitted). Although the storage device in the present embodiment is the flash memory 33, the storage device is another non-temporary storage medium capable of holding data regardless of the length of time for storing information, for example, ROM, RAM, etc. It may be configured.

  The input unit 34 includes an input terminal of one or more interfaces conforming to a predetermined standard (for example, Universal Serial Bus (USB)), and functions as an input port for connecting the CB 30 to an external device. In the present embodiment, a plurality of measuring devices 50 of the measuring devices 1 to N can be connected to the input unit 34. The measuring device 50 is various devices used at a medical site. The measuring device 50 includes, for example, an electrocardiograph for performing an electrocardiogram examination, an electroencephalograph for performing an electroencephalogram measurement, an ultrasonic diagnostic apparatus, an MRI apparatus, an X-ray CT apparatus, a personal computer (PC), etc. It is an information processor etc. which output. The input unit 34 acquires information input from the connected measuring device 50. The information input from the measuring device 50 is, for example, information corresponding to an image, a sound, or the like indicating the content measured or imaged by the measuring device 50, and hereinafter also referred to as “device information”.

  The wireless communication unit 36 is a controller for connecting to the network 11 by wireless communication and performing wireless communication with another HMD 10 connected to the network 11. The operation unit 37 inputs and outputs an input signal and the like corresponding to the operation by the user. The connection controller 35 is electrically connected to the connection controller 21 of the HD 20 through the harness 7 to perform wired communication.

  Next, the electrical configuration of the HD 20 will be described. The HD 20 includes a connection controller 21, an image display unit 22, a microphone 25, and a speaker 26. The connection controller 21, the image display unit 22, the microphone 25 and the speaker 26 are electrically connected. The connection controller 21 is electrically connected to the connection controller 35 of the CB 30 via the harness 7 to perform wired communication. The microphone 25 converts analog sound input from the outside of the housing 20A (for example, the mouth of the user) into digital sound data, and outputs the sound data. The speaker 26 converts sound data received via the connection controller 21 from digital to analog sound, and outputs the sound to the outside of the housing 20A (for example, the user's ear). The microphone 25 and the speaker 26 are not limited to the usual air conduction type microphone and speaker, and may be of the bone conduction type. As described above, the image display unit 22 displays an image based on the video signal.

  A procedure in the case where the user of the HMD 10 uses the information output system 100 will be described. In the present embodiment, the information output system 100 includes three HMDs 10 of HMDs 10A, 10B, and 10C. It is assumed that the medical site in the present embodiment is a scene of surgery. The role of each user of the HMD 10 in the medical field is, for example, a surgeon, a first assistant and an anesthesiologist. The role indicates the participation mode of each user at the medical site. Among the roles, it is assumed that the surgeon has given specific authority to control the medical site in advance.

  First, the user of the HMD 10 connects the measuring device 50 used at the medical site to the input unit 34 of the CB 30. In the present embodiment, it is assumed that, among the measuring devices 50, the measuring devices 1 to 3 are connected to the input unit 34. In the present embodiment, for example, the measuring device 1 is an ultrasonic diagnostic apparatus, the measuring device 2 is an electroencephalograph, and the measuring device 3 is a heart rate monitor. The measuring devices 1 to 3 may be connected only to a part of the HMDs 10 included in the information output system 100 such as the HMD 10A, or connected to each of all the HMDs 10 included in the information output system 100. It is also good. Thereafter, the user of the HMD 10 establishes wireless communication among the HMDs 10A, 10B, and 10C. Between the HMDs 10A, 10B, and 10C, various types of information transmitted and received by wireless communication are referred to as device information. The device information includes, for example, information (for example, a user ID or device ID described later) for specifying which HMD 10 the HMD 10 of the transmission source is in in its header region. In addition, when this wireless communication is established, the sound such as voice collected by the microphone 25 of the other HD 20 is output from the speaker 26. Thereby, the user can talk with other users through the microphone 25 and the speaker 26.

  The device information table 60 will be described with reference to FIG. The device information table 60 stores information on the pattern of the device information for each of the measuring devices 50. As shown in FIG. 2, in the device information table 60, a measurement device ID, a device pattern, a first threshold, and a second threshold are stored in association with each other. The measuring device ID is an ID assigned by the CPU 31 to identify which of the measuring devices 1 to N the measuring device 50 is. In the present embodiment, each of the measuring devices 1 to 3 corresponds to the measuring device ID.

  The device pattern is information capable of identifying from which measurement device 50 the device information input to the CPU 31 via the input unit 34 is output. In the present embodiment, the device pattern is information indicating a pattern of an image signal indicated by a device image input from each of the plurality of measurement devices 50. The device pattern is information on a template image for determining, by pattern matching, which measurement device 50 corresponds to the device image corresponding to the device information input to the CB 30 through the input unit 34. It is also good. The device pattern may be a pattern of an image signal unique to each of the measurement devices 50 included in the device information. Further, the device pattern may be various information that each of the measuring devices 50 outputs as header information of the device information.

  The first threshold and the second threshold indicate reference values for the CPU 31 to determine the device state which is the state of each of the measuring devices 50. Specifically, according to the measurement value measured by the measuring device 50, the measurement result indicated by the device image of the measuring device 50, and the like, the CPU 31 determines which of three states A, B, and C the device state is. Determine if it is. The state A is the lowest state among three steps in which the user needs to pay attention to the device information, such as the condition of the patient indicated by the device information is relatively good. The state B is a state in which attention should be paid to the device information rather than the state A, such as that the condition of the patient is worse than the state A. The state C is a state where the user needs to pay the most attention to the device information among the three steps, such as the patient's condition is worse than the state B. When the device information indicates information lower than the first threshold, the CPU 31 determines that the device state is the state A. When the device information indicates information of the first threshold or more and less than the second threshold, the CPU 31 determines that the device state is the state B. If the device information indicates information equal to or greater than the second threshold, the CPU 31 determines that the device state is the state C.

  The user information table 70 will be described with reference to FIG. As shown in FIG. 3, in the user information table 70, the user ID, the device ID, the role information, and the characteristic flag are stored in the order of “NO.”. The user ID is identification information for identifying a user who uses the information output system 100. The device ID is identification information for identifying the HMD 10 used by the user identified by the corresponding user ID. The role information indicates one of “operator”, “first assistant”, and “anesthesiologist”, which is the role of each user identified by the corresponding user ID.

  The characteristic flag is a flag in which “1” is stored and turned “ON” and “0” is stored and turned “OFF”, and the characteristic flag corresponding to the role to which the specific authority is given is set to ON. Be done. When the user information table 70 starts executing the information output process, the NO. The characteristic flag corresponding to 1 is set to be "ON". For example, while the information output process is in progress, a part of the user may leave the medical field. In this case, the user corresponding to the user ID "U0001" to which the specific authority is given ends the use of the HMD 10 corresponding to the device ID "HMD 10A" and leaves the wireless communication among the HMDs 10A, 10B, 10C. There is something to do. In such a case, the CPU 31 sets the characteristic flag corresponding to the next largest "NO." To "NO." Corresponding to the user ID for which the specific flag has been previously set "ON". And the characteristic flag previously set to "ON" is set to "OFF". As described above, “NO.” In the user information table 70 indicates the transition order in which the characteristic flag transitions in the user information table 70.

  In the present embodiment, the sound information transmitted to the speaker 26 of the HD 20 of the other HMD 10 via the microphone 25 of the HD 20 of the other HMD 10 has priority in the order of “NO.” In the user information table 70. It is provided. When plural pieces of sound information are received from plural other HMDs 10 at the same time, the CPU 31 sets the sound information transmitted from the HMD 10 corresponding to the device ID having the higher order of "NO." In the order of "NO." The sound information output from the HMD 10 corresponding to the low device ID is output to the speaker 26 earlier. When a plurality of sounds are output from the speaker 26, it may be difficult to distinguish individual sounds. In particular, it is not preferable at a medical site to hear and hear the sound related to the user ID to which the specific authority is given. The CPU 31 changes the output timing of the sound information transmitted from the other HMDs 10 according to the order of “NO.”, Thereby reducing the user's omission of the sound regarding the higher sound information in the order of “NO.” it can.

  The information output process will be described with reference to FIGS. 4 and 5. As described above, the HMD 10 is shipped with the information output program stored in the flash memory 33 in advance. The information output program is a program executed by the CPU 31 in the CB 30 of the HMD 10. The CPU 31 that has executed the information output program determines the priority of each device state according to the user ID, and performs a process of displaying the device image based on the device information on the HMD 10 based on the determined priority. In the following, it is assumed that the CPU 31 of the HMD 10A is executing an information output program.

  A process performed by the CPU 31 with the execution of the information output process will be described. When the user operates the power switch in the operation unit 37 of the CB 30, the CPU 31 performs an operation associated with a predetermined initial setting process (not shown) at the time of activation. The CPU 31 initializes flags and data stored in the RAM 32, and writes initial values of the flags and data stored in the flash memory 33 in the RAM 32.

  When the above-described initial setting process is completed, the CPU 31 starts an information output process. As shown in FIG. 4, when the information output process is started, the CPU 31 is established among the HMDs 10A, 10B, and 10C. Device information of the other HMD 10 is acquired via wireless communication. The CPU 31 refers to the user information table 70 and acquires the user ID corresponding to the HMD 10 of the transmission source based on the information specifying the HMD 10 of the transmission source included in the header area of the acquired device information (S11). Further, the CPU 31 acquires a user ID corresponding to the HMD 10 of itself based on the information included in the header area of the device information to be transmitted to the other HMD 10 (S11). Note that this process allows the CPU 31 to grasp which HMD 10 is connected to the network 11.

  The CPU 31 refers to the first priority table 80 stored in the flash memory 33 (S12). The first priority table 80 will be described with reference to FIG. The first priority table 80 defines the priority at which the device information is output to the HMD 10 using a predetermined first priority index for each measuring device ID. When the user uses the HMD 10, the device information output from the measuring device 50 connected to the HMD 10 is required to the same extent, and some device information is prioritized over other device information. There are cases where it is necessary. The first priority index is an index indicating the priority of such device information. The first priority index may be derived by quantifying the priority of device information by prior experiments or the like. Here, when a plurality of users use the respective HMDs 10, device information required by the users may differ among the users depending on the role even in the same medical site. The first priority table 80 sets a first priority index for each measuring device ID for each user ID. Therefore, the HMD 10 can set the priority of the device information according to the role of the user. Such a priority for each measuring device ID defined for each user ID is hereinafter referred to as a first priority.

  As shown in FIG. 6, the first priority indexes of the measuring devices 1 to 3 associated with the user ID “U0001” are all “30”. For example, such a first priority is set when the role of the user is the role to which attention should be paid to the same degree in any device information output from the measuring devices 1 to 3. On the other hand, the first priority indexes of the measuring devices 1 to 3 associated with the user IDs "U0002" and "U0003" are assigned different values according to their roles.

  The "update prohibition flag" column provided in the first priority table 80 is provided to set whether to prohibit the update of the first priority in the table update process (see FIG. 17) described later. There is. In FIG. 6, "0" is stored and the update prohibition flag corresponding to user ID "U0001" and "U0002" is made "OFF". The update prohibition flag corresponding to the user ID "U0003" stores "1" and is set to "ON". In the table updating process, it is determined that updating is prohibited for data strings for which the update prohibition flag is "ON", and update is not prohibited for data strings for which the update prohibition flag is "OFF".

  It returns to the explanation of FIG. The CPU 31 acquires information indicating the first priority for each of the measurement device IDs corresponding to each user ID in the first priority table 80 (S13). The CPU 31 acquires device information from each of the measuring devices 50 connected to the HMD 10 (S15). In this process, the CPU 31 first determines, among the plurality of input terminals provided in the input unit 34, whether device information is input to the input terminal with the smallest number. When device information is input, the CPU 31 acquires the input device information. Hereinafter, the CPU 31 controls the input terminal from the input terminal with the largest number next to the smallest number to the input terminal with the largest number among the plurality of input terminals provided in the input unit 34. It is determined whether information is input, and when device information is input, acquisition of device information is repeatedly executed.

  The CPU 31 refers to the device information table 60 stored in the flash memory 33 (S16). The CPU 31 acquires the measuring device ID and the device information for each of the device information acquired in the process of S15 (S18). In this process, the CPU 31 compares the pattern indicated by the acquired device information with the plurality of device patterns stored in the device information table 60, and the pattern indicated by the acquired device information is any of the plurality of device patterns. Determine if it matches. When one of the plurality of device patterns matches the pattern indicated by the acquired device information, the CPU 31 specifies the measurement device ID associated in the device information table 60 with the device pattern determined to match. That is, the measuring device ID of the measuring device 50 which has output the device information to be determined is specified. The CPU 31 determines which one of the states A to C the device state of the device information to be determined is based on the first threshold and the second threshold associated with the measurement device ID specified in the device information table 60. . For example, in the ultrasonic image 221 which is an apparatus image related to the measuring apparatus 1 shown in FIG. 14, the apparatus state is determined using a value indicating the degree of fluctuation of the image as a threshold. In the waveform image 222 which is an apparatus image related to the measurement device 2 shown in FIG. 14, the waveform based on the measurement value of the measurement device 2 exceeds the horizontal axis with the horizontal axis indicated by the lower side of the frame line surrounding the waveform image 222 as a threshold. The device state is determined to such an extent that it is drawn. In the electrocardiogram image which is an apparatus image regarding the measuring apparatus 3 shown in FIG. 14, an apparatus state is determined by using a predetermined numerical value of the heart rate as a threshold. When the device information is audio information, the device state is determined with a predetermined volume, frequency, etc. indicated by the audio information as a threshold. For example, with regard to device information indicated by a numerical value such as a heart rate, a blood pressure value, etc., the value itself may be treated as the value of the numerical value itself or a value obtained by multiplying the numerical value by a predetermined coefficient. By performing these processes on the other device information acquired in S15, the measurement device ID and the device state corresponding to each of the device information acquired in the process of S15 are acquired. The CPU 31 stores the measuring device ID and the device state corresponding to the measuring device ID in the RAM 32.

  The CPU 31 refers to the second priority table 90 stored in the flash memory 33 (S19). The second priority table 90 will be described with reference to FIG. The second priority table 90 defines the priority of the device information according to the device state, using a predetermined second priority index for each measuring device ID. When the user uses the HMD 10, the degree to which the device information is required may differ depending on the device state even with the same measuring device 50. The second priority index is not a single value fixed for each measuring device 50, but is a value that changes according to the device state for each measuring device 50, and is an index indicating the priority of the device information according to the device state It is. The second priority index may be derived by quantifying the priority of the device information by prior experiments or the like. In the present embodiment, regardless of the measurement device ID, the second priority index in state A is “30”, the second priority index in state B is “50”, and the second priority index in state C is “80”. And the second priority table 90. For example, the degree of necessity for each piece of device information may differ among the measuring devices 50 depending on the device state. In this case, different second priority indexes may be defined for each of the device states for each measurement device ID. Such a priority for each device state defined for each measuring device ID is hereinafter referred to as a second priority.

  It returns to the explanation of FIG. The CPU 31 acquires a second priority for each measuring device ID according to the device state, based on the measuring device ID acquired in the process of S18 and the device state corresponding to the measuring device ID (S21). In the present embodiment, in the process of S18, the “state B” is for the measuring instrument ID “measuring instrument 1”, the “state C” is for the measuring instrument ID “measuring instrument 2”, and the “state C” is for the measuring instrument ID “measuring instrument 3”. It is assumed that the state C "is acquired correspondingly. In this case, "50" shown in box 91, assuming that the device state of "measuring device 1" is "state B", and "80" shown in box 92, that the device state of "measuring device 2" is "state C" It is assumed that “30” shown in the box 93 is assumed to be acquired as the second priority, as the device state of “measuring device 3” is “state A”.

  The CPU 31 is a third priority corresponding to each of the user ID, the measuring device ID, and the device state based on the first priority acquired in the processing of S13 and the second priority acquired in the processing of S21. The priority is calculated (S22). In this process, the CPU 31 generates, for example, a third priority table 110 as shown in FIG. 8 in the flash memory 33, and calculates a third priority. The third priority table 110 associates each user ID with each measuring device ID. First, the CPU 31 registers in the third priority table 110 the first priority (enclosure 801 in FIG. 8) for each of the measurement device IDs corresponding to each user ID acquired in the process of S13. Next, the CPU 31 adds, to the first priority, the second priority (enclosure 901 in FIG. 8) for each of the measurement device IDs according to the device state acquired in the process of S21. At this time, since the device state of “measurement device 1” is “state B” in the second priority table 90, the second priority “50” with respect to “measurement device 1” of the third priority table 110 Is added. Similarly, since the device state of “measurement device 2” is “state C” in the second priority table 90, the second priority “80” for “measurement device 2” of the third priority table 110 Is added. Since the device state of “measuring device 3” is “state A” in the second priority table 90, the second priority “30” is added to “measuring device 1” of the third priority table 110 Ru. Thus, the third priority is calculated according to each of the user ID, the measuring device ID, and the device state. Thus, the CPU 31 does not calculate the priority of the device information based on only the first priority or only the second priority, but the status of each user ID and the status of the device status of each measurement device ID The third priority can be calculated as the priority of the device information according to each of the above.

  The values shown in angle brackets (“”) in FIG. 8 indicate the order of the third highest priority for each user ID. For example, in the user ID "U0001", the value of the third priority is "80" in the "measuring device 1", "110" in the "measuring device 2", and "60" in the "measuring device 3". Therefore, in the order of the third priority in “U0001”, “measurement device 2” is “1”, “measurement device 1” is “2”, and “measurement device 3” is “3”.

  Next, as shown in FIG. 5, the CPU 31 refers to the device information amount table 120 stored in the flash memory 33 (S31). The device information amount table 120 will be described with reference to FIG. The device information amount table 120 defines the device information amount which is the information amount of each of the device information output from the measuring device 50 using a predetermined device information amount index for each measuring device ID. The device information amount is, for example, an amount of information included in a device image corresponding to the device information. The device information amount is, for example, an amount of information included in sound information corresponding to the device information. The device information amount index may be derived by quantifying the device information amount of the device information by a preliminary experiment or the like. In the present embodiment, the measuring device 1 corresponds to an ultrasonic diagnostic apparatus, the measuring device 2 corresponds to an electroencephalograph, and the measuring device 3 corresponds to a heart rate meter, but in the device information amount table 120, the device information amount corresponding to each measuring device 50 Different values are defined as exponents.

  It returns to the explanation of FIG. The CPU 31 acquires the device information amount for each measuring device ID from the referred device information amount table 120 (S32). The CPU 31 refers to the user processing capacity table 130 stored in the flash memory 33 (S33).

  The user processing capacity table 130 will be described with reference to FIG. The user processing capacity table 130 measures, for example, the ability of the user of the HMD 10 to visually recognize the device image based on the device information and make a judgment according to the medical site, that is, the ability to process the device information. Each is defined using a predetermined processing capacity index. In the present embodiment, the processing capability index indicates the ability of the user to process a predetermined amount of device information per predetermined time. The processing capability of the device information may differ depending on the user depending on the proficiency of processing the device information, the experience of the user, and the like. Further, the processing capability may differ depending on which measurement device 50 the device information of the same user is. In addition, the processing of the user on the device information of the same measuring device 50 may differ depending on the role of the user. For example, since it is conceivable that the operator and the anesthesiologist determine the device image from different viewpoints for the same device image of the electroencephalograph, the processing capability for the same device information is different for each role. It may be different. Therefore, the user processing capacity table 130 sets the processing capacity index for each measurement device ID for each user ID. Taking these various factors into consideration, the throughput index may be derived by quantifying the processing power of the device information by prior experiments and the like. Such processing capacity for each measuring device ID defined for each user ID is hereinafter referred to as user processing capacity.

  It returns to the explanation of FIG. The CPU 31 acquires the user processing capacity for each measuring device ID defined for each user ID from the referenced user processing capacity table 130 (S35). The CPU 31 calculates the processing load amount according to the user ID and the measurement device ID based on the device information amount acquired in the process of S32 and the user processing capacity acquired in the process of S35 (S36). The processing load amount is obtained by quantifying the load required when processing each piece of device information with the user processing capacity of each user.

  In this process, the CPU 31 generates, for example, a processing load amount table 140 as shown in FIG. 11 in the flash memory 33, and calculates the processing load amount. The processing load amount table 140 associates each user ID with each measurement device ID. In the present embodiment, the processing load amount is calculated as a result of dividing the amount of device information included in each piece of device information by the respective user processing capabilities. First, the CPU 31 registers in the processing load amount table 140 the amount of information (enclosure 1201 in FIG. 11) for each measurement device ID acquired in the process of S32. Next, the CPU 31 divides each amount of information registered in the processing load amount table 140 by the user processing capacity (box 1301 in FIG. 11) for each measurement device ID corresponding to each user ID acquired in the process of S35. As a result, the processing load amount for each measuring device ID corresponding to each user ID is calculated.

  Next, as shown in FIG. 5, the CPU 31 refers to the simultaneous processing amount table 150 stored in the flash memory 33 (S39). The simultaneous processing amount table 150 will be described with reference to FIG. Some users are good at viewing and processing a plurality of device images simultaneously based on a plurality of device information, for example, but it is not good to view a plurality of device images at the same time. Some people are good at processing each one at a time. The simultaneous processing amount table 150 defines the amount of information that each user can process per predetermined time using a predetermined simultaneous processing amount index according to the characteristics of the processing of the device information of the user. For users who are good at processing multiple device images simultaneously, the simultaneous processing index of the simultaneous processing amount table 150 is defined to be large. In this embodiment, as shown in FIG. 12, the simultaneous processing index is “6” for the user ID “U0001”, “7” for the user ID “U0002”, and “5” for the user ID “U0003”. Are defined in the simultaneous processing amount table 150.

  Next, as shown in FIG. 5, the CPU 31 acquires the simultaneous processing amount for each user ID from the referenced simultaneous processing amount table 150 (S39). The CPU 31 specifies the information amount of the device information in a range not exceeding the simultaneous processing amount acquired in the process of S39, according to the third priority calculated in the process of S22 and the processing load amount calculated in the process of S36. (S41).

  This process will be specifically described. The values stored in the processing load amount table 140 shown in the upper part of FIG. 13 indicate the processing load amounts according to the user ID and the measuring device ID, which are the calculation results calculated in the process of S36. Further, in the processing load amount table 140 shown in the upper part of FIG. 13, the value shown in the angle brackets (“”) is the third priority calculated in the process of S22. The CPU 31 adds, for each user ID, the processing load amount for each measurement device ID in the descending order of the third priority within a range not exceeding the value indicated by the simultaneous processing amount acquired in the process of S39. Then, the CPU 31 specifies the measuring device ID to which the processing load index can be added within the range not exceeding the value indicated by the simultaneous processing amount.

  In the upper part of FIG. 13, for the user ID “U0001”, the processing load amount “2” of the measuring device 2 whose third priority is “1” and the processing load of the measuring device 1 whose third priority is “2” The processing load amount “1” of the measuring device 3 having the amount “1.5” and the third priority “3” is shown in the processing load amount table 140. The result of adding these processing load amounts in the order of the third priority is “2 + 1.5 + 1 = 4.5”. This result does not exceed "6" which is the simultaneous processing amount of the user ID "U0001" acquired in the process of S39. Therefore, the CPU 31 sets all of the measuring devices 1 to 3 as a specific target in the process of S41.

  For the user ID “U0002”, the processing load amount “1” of the measuring device 3 whose third priority is “1” and the processing load amount “4” of the measuring device 2 whose third priority is “2” When is added, the addition result does not exceed "7" which is the simultaneous processing amount of the user ID "U0002". However, the processing load amount "1" of the measuring device 3 whose third priority is "1", the processing load amount "4" of the measuring device 2 whose third priority is "2", and the third priority “8” which is the addition result obtained by adding the processing load amount “3” of the measurement device 1 where “3” is “3” exceeds “7” which is the simultaneous processing amount of the user ID “U0002”. Therefore, the CPU 31 sets the measuring device 3 and the measuring device 2 corresponding to the processing load amount in the range not exceeding the simultaneous processing amount of the user ID “U0002” as a specific target in the process of S41. Similarly, for the user ID “U0003”, the processing load amount of the measuring device 2 having the third priority “1” is “5”. Therefore, the CPU 31 sets only the measuring device 2 corresponding to the processing load amount in the range not exceeding “5” which is the simultaneous processing amount of the user ID “U0003” as the specific target in the processing of S41.

  Next, as shown in FIG. 5, the CPU 31 outputs an instruction to output device information to the HD 20 via the connection controller 35 in accordance with the contents specified in the process of S41 (S42). In this process, in the present embodiment, the CPU 31 determines that the device information corresponding to the measuring device ID specified in the process of S41 is output to the HD 20. That is, as shown in the processing load amount table 140 in the lower part of FIG. 13, the CPU 31 determines to output all the device information of the measuring devices 1 to 3 to the HD 20 for the user ID “U0001”. The CPU 31 determines to output the device information of the measuring device 3 and the measuring device 2 to the HD 20 for the user ID “U0002”. The CPU 31 determines that only the device information of the measuring device 2 is output to the HD 20 for the user ID “U0003”.

  In the present embodiment, when the device image based on the plurality of device information is output to the image display unit 22 in the process of S42, the CPU 31 controls the device image with the third priority to a device with the third priority. Display using an area larger than the image. When the output of the device image based on the device information corresponding to the measuring devices 1 to 3 is determined as shown in the processing load amount table 140 in the lower part of FIG. 13, the CPU 31 sets the user ID “ Each device image is displayed on the image display unit 22 of the HMD 10 of “U0001”. Here, the CPU 31 causes the image display unit 22 to display the waveform image 222 which is an apparatus image related to the measurement apparatus 2 having the highest third priority, using a region larger than other apparatus images. The CPU 31 causes the image display unit 22 to display an ultrasound image 221, which is a device image related to the measurement device 1 having the second highest priority, using an area smaller than the waveform image 222. The CPU 31 causes the image display unit 22 to display a heart rate image 223 that is an apparatus image related to the measurement apparatus 3 with the lowest third priority, using an area smaller than the ultrasound image 221. By doing this, the CPU 31 can show the device image regarding the device information having the higher third priority more easily to the user.

  Here, the CPU 31 may send an instruction to display the selected image 225 (see the upper part of FIG. 15) to the image display unit 22 in the process of S42. In this case, the CPU 31 may cause the image display unit 22 to display a device image corresponding to the input of a predetermined instruction accompanying the display of the selected image 225 on the image display unit 22.

  As shown in FIG. 15, the selection image 225 is an image for causing the user to select desired device information. Here, an example in which the selected image 225 is displayed on the image display unit 22 of the HMD 10 corresponding to the user ID “U0001” in which the third priority is the order of the measuring device 2, the measuring device 1, and the measuring device 3 Explain to. The selected image 225 includes a first image 225A, a second image 225B and a third image 225C. The first image 225A is an image for selecting the waveform image 222 of the measurement device 2 having the highest third priority. The second image 225 </ b> B is an image for selecting an ultrasound image 221 of the measurement device 1 having the third highest priority. The third image 225C is an image for selecting the heart rate image 223 of the measuring device 3 with the lowest third priority. The first image 225A, the second image 225B, and the third image 225C are arranged from the front side to the rear side of the image display unit 22 in descending order of the third priority, and thus the user can visually recognize the third priority Can be shown.

  When the CPU 31 causes the image display unit 22 to display the selected image 225, the CPU 31 operates the operation button of the operation unit 37 to select one of the first image 225A, the second image 225B, and the third image 225C. Wait for an instruction to select to be input. In the upper part of FIG. 15, the first image 225A is indicated by a double frame, and indicates that an instruction to select the first image 225A is input. Thereafter, the CPU 31 displays the waveform image 222 corresponding to the first image 225A in response to the input of the instruction to select the first image 225A (see the lower part of FIG. 15). The CPU 31 can cause the image display unit 22 to display an apparatus image according to the third priority by causing the image display unit 22 to display the selected image 225. Also, depending on the current situation of the medical site, the user may want to view equipment information different from the equipment information determined to be higher than the third priority. The CPU 31 can use the selection image 225 to visually indicate to the user, along with the third priority, which device information is determined to be higher than the third priority. Therefore, since the user can arbitrarily select the device information to be viewed while grasping the third priority by the selection image 225, the device image according to the third priority is uniformly displayed on the image display unit 22. Rather than being displayed, the convenience of the HMD 10 is improved.

  As shown in the upper part of FIG. 15, in the selected image 225, the third image 225C corresponding to the heart rate image 223 with the lowest third priority is shown at higher luminance than the first image 225A and the second image 225B. Be Therefore, the third image 225C is displayed in a mode in which the third image 225C is less visible than the first image 225A and the second image 225B. That is, the image display unit 22 is configured such that the third image 225C relating to the device information of the measuring device 3 has a smaller amount of information than the first image 225A and the second image 225B relating to the device information of the measuring device 1 and the measuring device 2 Is displayed on. The CPU 31 displays the third image 225C in such a display mode in which the amount of information for the user is suppressed, so that among the three types of device images shown in the selection image 225, the device image corresponding to the third image 225C. The user can be visually shown that the third priority is the lowest.

  In the case where the device image is displayed by the process of S42 on the image display unit 22 of the HMD 10 corresponding to the user ID “U0002” in which the third priority is the order of the measuring device 3, the measuring device 2, and the measuring device 1. Will be described with reference to FIG. In this case, as shown in the lower part of FIG. 13, the CPU 31 determines to output the device information of the measuring device 3 and the measuring device 2 to the HD 20 by the process of S41. In such a case, the CPU 31 causes the image display unit 22 to display the heart rate image 223 related to the measuring device 3 determined to output in the process of S41 and the waveform image 222 related to the measuring device 2 (see upper stage in FIG. 16). . Then, the ultrasound image 221 related to the measuring device 1 is not displayed together with the heart rate image 223 and the waveform image 222. As described above, with regard to the device information output from the measuring device 1 having the third lowest priority, the CPU 31 suppresses the output with respect to the device information having the third highest priority, thereby processing the user simultaneously. A device image based on device information of an amount of information corresponding to the amount can be provided to the user.

  In this case, the CPU 31 may output the device information output from the measuring device 1 having the third lowest priority, at a different timing with respect to the device information of the higher third priority. For example, as shown in the upper part of FIG. 16, the CPU 31 first causes the image display unit 22 to display the heart rate image 223 regarding the measuring device 3 with the third highest priority and the waveform image 222 regarding the measuring device 2. Thereafter, after a predetermined time has elapsed, the CPU 31 switches the device image displayed on the image display unit 22 to the ultrasonic image 221 related to the measuring device 1 (see the lower part of FIG. 16). Thus, by shifting the output timing of the plurality of pieces of device information according to the third priority, the CPU 31 first outputs the device information within the range of the simultaneous processing amount of the user, and thereafter the range of the simultaneous processing amount External device information can be output. As described above, since the CPU 31 can control the output of the device information at different timings according to the third priority, the user can easily grasp more device images and device sounds.

  When the device information of the plurality of measurement devices 50 indicates the same third priority, the CPU 31 sets output timings of the plurality of device information at predetermined intervals in an arbitrary order according to the device information. You may shift it. For example, the HMD 10 defines in advance a measurement device ID to which device information is prioritized when the third priority is equal. When a plurality of pieces of device information indicate the same third priority, the CPU 31 outputs the pieces of device information while shifting the timing in order from the device information corresponding to the predetermined measurement device ID. As a result, the HMD 10 can make it easier for the user to grasp the device information than outputting a plurality of pieces of device information at one time. In particular, when the device information is audio information, it may be difficult for the user to distinguish individual audio information if a plurality of audio information are output from the speaker 26 at one time. In this embodiment, since each audio | voice information is output from the speaker 26 at predetermined intervals, it becomes easy for a user to discriminate | determine each audio | voice information easily.

  It returns to the explanation of FIG. The CPU 31 determines whether an instruction for ending the information output process has been input through the operation unit 37 (S43). If the instruction to end the information output process is not input (S43: NO), the CPU 31 returns the process to S11 (see FIG. 4) and repeatedly executes a series of information output processes. When the instruction to end the information output process is input (S43: YES), the CPU 31 ends the information output process.

  The table update process will be described with reference to FIG. The table update process is executed by the main program in parallel with the above-described information output process. The table update process is a process for updating the first priority and the second priority defined in the first priority table 80 and the second priority table 90 under predetermined conditions. When the table update process is started, the CPU 31 determines whether or not update information for updating at least one of the first priority table 80 and the second priority table 90 has been acquired via the operation unit 37. (S51). The update information may be acquired via the operation unit 37 of the HMD 10 of its own and may be acquired from the other HMD 10 via the operation unit 37 of the other HMD 10. If the update information has not been acquired (S51: NO), the CPU 31 repeats the process of S51.

  When the update information is acquired (S51: YES), the CPU 31 has the authority to specify the update information based on the device ID or the like of the HMD 10 that is the transmission source of the update information, or based on the device ID or the like of itself. It is determined whether it is based on role information (S52). In this process, the CPU 31 refers to the user information table 70 and determines that the update information is based on the role information having the specific authority when the specific flag is set to "ON" for the device ID related to the update information. . When the update information is not based on the role information having the specific authority (S52: NO), the CPU 31 returns the process to the determination of S51.

  When the update information is based on the role information having the specific authority (S52: YES), the update information is a numerical value related to the area of the first priority table 80 and the second priority table 90 for which the update prohibition setting is made. It is determined whether the information is information to be updated (S53). In this process, the CPU 31 is information for updating the numerical value related to the data string of which the update prohibition flag is “ON” among the first priority table 80 and the second priority table 90. In this case, it is determined that transmission prohibition is set. When the update information is information for updating the numerical value related to the area for which the update prohibition setting is made (S53: YES), the CPU 31 returns the process to the determination of S51.

  If the update information is not information for updating the numerical value related to the area for which update prohibition is set (S53: NO), the CPU 31 determines the first priority table 80 and the second priority according to the content indicated by the update information. The first priority and the second priority of the degree table 90 are updated (S54). The CPU 31 returns the process to S51.

  The CPU 31 executes the table update process, for example, according to update information based on role information having a specific authority, to update to the first priority and the second priority suitable for each situation of the medical site it can. Therefore, the CPU 31 can calculate the third priority calculated according to the first priority and the second priority as one corresponding to the situation of the medical site at that time. In addition, since the first priority and the second priority are set through predetermined experiments, etc., the first priority and the second priority are updated by the person who does not have the specific authority without consideration. Is not desirable. Therefore, useless updating of the first priority and the second priority can be prevented by limiting users who can update the first priority and the second priority to users related to role information having a specific authority. In addition, the CPU 31 may perform output control of the device information in accordance with the third priority calculated based on the first priority and the second priority updated by the user regarding the role information having the specific authority. it can. In addition, since it is also possible to set update prohibition to the first priority and the second priority, the HMD 10 erroneously sets the table updating means to the range not to be updated among the first priority and the second priority. It can be prevented from being updated.

  As described above, the CPU 31 refers to the user information table 70 and acquires the user ID corresponding to the HMD 10 based on the acquired device information (S11). The CPU 31 acquires device information from each of the measuring devices 50 connected to the HMD 10 (S15). The CPU 31 acquires the measuring device ID and the device information for each of the device information acquired in the process of S15 (S18). The CPU 31 is a third priority that is a priority according to each of the user ID, the measuring device ID, and the device state, based on the first priority obtained in the process of S13 and the second priority obtained in the process of S21. Is calculated (S22). Therefore, for example, in the case where the measurement values of some of the plurality of measurement devices 50 are abnormal values or the like among the plurality of measurement devices 50, the first priority of the device information of each of the plurality of measurement devices according The device information is output with a third priority based on the second priority according to the device state of the measuring device 50. Therefore, the HMD 10 does not output the device information based on only the predetermined priority by calculating the third priority, but according to the third priority, the device according to the situation of the medical field. It can output information.

  Depending on the current situation at the medical site, the user may want to view equipment information different from the equipment information determined to be higher than the third priority. In the process of S42, the CPU 31 transmits an instruction to display the selected image 225 to the image display unit 22, and the device image corresponding to the input of the predetermined instruction accompanying the display of the selected image 225 on the image display unit 22 is performed. , And display on the image display unit 22. Therefore, the user can arbitrarily select the device information to be viewed while grasping the third priority by the selection image 225. Therefore, the convenience of the HMD 10 is improved.

  When a device image based on a large amount of device information is displayed on the image display unit 22 at one time, it may be difficult to grasp the device image at one time depending on the situation of the user. Similarly, with regard to device voice based on device information, even if a plurality of device voices are simultaneously output from the speaker 26, it may be difficult for the user to grasp each device voice. Since the CPU 31 suppresses the output of the device information of the third priority lower than the device information of the third higher priority (S41), the device information of the information amount suitable for the user's situation is Can be provided.

  Since the HD 20 is worn on the head of the user, the display area of the image display unit 22 has an upper limit, so it may be difficult to display a plurality of device images on the image display unit 22 at one time. In addition, the user processing capability for the device image displayed on the image display unit 22 may be different for each user. The CPU 31 acquires the device information amount for each measurement device ID (S32). The CPU 31 acquires the user processing capacity for each measuring device ID defined for each user ID (S35). Then, the CPU 31 calculates the processing load amount according to the user ID and the measurement device ID based on the device information amount and the user processing capacity (S36). Furthermore, the CPU 31 specifies, for each user ID, a measurement device ID to which the processing load amount can be added within a range not exceeding the simultaneous processing amount acquired in the process of S39 according to the third priority and the processing load amount. S41). Then, the CPU 31 performs output control of device information related to the identified measuring device ID (S42). Therefore, the HMD 10 can output device information of an amount of information corresponding to each of the output capabilities of the image display unit 22 and the speaker 26 and the user processing capabilities.

  Even when a plurality of device images are displayed on the image display unit 22 at one time, it may be difficult for the user to properly process the device images. The CPU 31 can control output of device information having the same third priority at different timings according to the device information. Therefore, the convenience of the HMD 10 is improved.

  The CPU 31 determines whether update information for updating at least one of the first priority table 80 and the second priority table 90 has been acquired (S51). When the update information is acquired (S51: YES), the CPU 31 has the authority to specify the update information based on the device ID or the like of the HMD 10 that is the transmission source of the update information, or based on the device ID or the like of itself. It is determined whether it is based on role information (S52). When the update information is based on role information having a specific authority (S52: YES), the CPU 31 determines the first priority of the first priority table 80 and the second priority table 90 according to the content indicated by the update information. The second priority is updated (S54). On the other hand, when the update information is not based on the role information having the specific authority (S52: NO), the CPU 31 does not update the first priority and the second priority based on the update information. Therefore, in response to the determination that the user having the specific right should update, the output of the device information is controlled in accordance with the third priority based on the update information. Therefore, the HMD 10 can provide the user with device information more appropriate to the situation at the medical site.

  The user corresponding to the user ID to which the specific authority is given may end the use of the HMD 10 and may leave the wireless communication among the HMDs 10A, 10B, 10C. In such a case, in the user information table 70, the characteristic flag corresponding to the next largest "NO." Is "NO" corresponding to the user ID for which the specific flag has been previously set "ON". It is considered as "ON". Therefore, each time a user ID is acquired, a specific characteristic according to the situation at that time is given to the user ID.

  The CPU 31 determines whether the update information is information for updating a numerical value related to an area for which update prohibition is set among the first priority table 80 and the second priority table 90 (S53). When the update information is information for updating the numerical value related to the area for which the update prohibition setting is made (S53: YES), the CPU 31 does not update the first priority and the second priority. Therefore, the HMD 10 can prevent the table updating unit from erroneously updating the first priority and the second priority to the extent not to be updated.
