[0027] An embodiment of the present invention (hereinafter referred to as the present embodiment) will be described below with reference to the drawings. Figure 1 is a schematic diagram showing a vital sign information display system 100 according to this embodiment. Figure 1 As shown, the vital sign information display system 100 includes: a vital sign information sensor 1, which is mounted on a physiological tissue (e.g., a finger, etc.) of a subject (e.g., a patient); and a vital sign information display device 2 (hereinafter referred to as display device 2), which is communicably connected to the vital sign information sensor 1. A pulse oximeter is described as an example of the vital sign information sensor 1 in this embodiment.

[0028] The vital sign information sensor 1 has a probe 12, a cable 13, and a connector 16. The probe 12 is, for example, wound around a finger of a subject, thereby being mounted on the finger of the subject. The cable 13 is configured so that the probe 12 and the connector 16 can be physically and electrically connected to each other through the cable 13. When the connector 16 is inserted into the connector insertion portion 21 of the display device 2, the vital sign information sensor 1 and the display device 2 are physically and communicatively connected to each other. In addition, the electrical signal output from the display device 2 in a state where the vital sign information sensor 1 and the display device 2 are physically and communicatively connected to each other is supplied to the probe 12 through the connector 16 and the cable 13.

[0029] The display device 2 is configured to visually present the vital signs information of the subject. The display device 2 can be a specific device (e.g., a vital signs information monitor) for displaying a trend graph of the vital signs information of the subject, or can be, for example, a personal computer, a workstation, a smart phone, a tablet computer, or a wearable device (e.g., a smart watch, AR glasses, etc.) that can be installed on a medical worker (e.g., an arm, a head, etc.). In addition, the display device 2 is communicatively connected to the WEB server 4 through the communication network 3. The communication network 3 is composed of at least one of the Internet, a LAN (local area network), and a WAN (wide area network). The WEB server 4 is arranged on the communication network 3 and is configured to provide electronic content of HTML files (WEB pages), PDF files, image files (e.g., still image files and motion image files, etc.) according to an access request from a terminal. In particular, the WEB server 4 is configured to send electronic content including information related to the vital signs information sensor 1 (in particular, information about the operation manual of the vital signs information sensor 1) to the display device 2 according to an access request from the display device 2.

[0030] Next, we will refer to Figure 2 The hardware configuration of the vital sign information sensor 1 and the display device 2 is described. Figure 2 1 is a diagram showing an example of the hardware configuration of the vital sign information sensor 1 and the display device 2. Figure 2 As shown, the vital sign information sensor 1 includes a memory 17 , a light transmitter 18 and a light receiver 19 .

[0031] The memory 17 is, for example, a ROM (read-only memory). The URL information representing the URL (Uniform Resource Locator) accessible to the electronic contents provided by the WEB server 4 is stored in the memory 17. The URL is, for example, composed of a communication protocol, a domain name, a directory name, and a file name. Incidentally, the URL may include the IP address of the WEB server 4 instead of the domain name. In addition, in the present embodiment, the URL information is stored in the memory 17 as an example of the URI (Uniform Resource Identifier) ​​information. However, the URN (Uniform Resource Name) information may be stored in the memory 17 instead of the URL information.

[0032] In addition, the memory 17 is, for example, provided on the connector 16 of the vital sign information sensor 1. Specifically, the memory 17 may be mounted on a circuit board provided in the connector 16.

[0033] The light emitter 18 is disposed on the probe 12 of the vital sign information sensor 1 and is configured to emit light toward a physiological tissue such as a finger of a subject. For example, the light emitter 18 has a red light LED configured to emit red light and an infrared light LED configured to emit infrared light. The red light LED and the infrared light LED are driven and controlled to emit red light and infrared light alternately. For example, when the pulse current supplied to the infrared light LED is at a high level, the pulse current supplied to the red light LED is at a low level. On the other hand, when the pulse current supplied to the infrared light LED is at a low level, the pulse current supplied to the red light LED is at a high level.

[0034] The light receiver 19 is provided on the probe 12 of the vital sign information sensor 1. The light receiver 19 is configured to receive light radiated from the light transmitter 18 and propagated or reflected by physiological tissues such as the finger of the subject, so that the light receiver 19 can generate a pulse wave signal (electric signal) representing the pulse wave. For example, the light receiver 19 is a photoelectric conversion element such as a PD (photodiode). The number of light receivers 19 is not particularly limited. For example, when the light transmitter 18 has a red light LED and an infrared light LED, the light receiver 19 has photosensitivity to the red light radiated from the red light LED and the infrared light radiated from the infrared light LED. The light transmitter 18 and the light receiver 19 serve as sensor elements configured to acquire pulse wave information (an example of vital sign information) related to the pulse wave of the subject. In addition, the sensor element is not limited to the light transmitter 18 and the light receiver 19. The type of the sensor element is not particularly limited as long as the sensor element is configured to acquire vital sign information from the subject.

[0035] Red light is not absorbed in large quantities by oxygenated hemoglobin (HbO2) contained in the blood circulating in the blood vessels of the finger. On the other hand, red light is absorbed in large quantities by hemoglobin (Hb) contained in the blood. That is, when the blood contains a large amount of oxygenated hemoglobin, a large amount of red light is transmitted through the finger and is received by the light receiver 19. On the contrary, when the blood does not contain a large amount of oxygenated hemoglobin, the intensity of the red light received by the light receiver 19 is small. Thus, the ratio of the intensity of the red light received by the light receiver 19 to the oxygenated hemoglobin in the blood changes accordingly. On the other hand, infrared light is not absorbed in large quantities by oxygenated hemoglobin and hemoglobin. More specifically, the difference between the absorption coefficient of oxygenated hemoglobin for infrared light and the absorption coefficient of hemoglobin for infrared light is not large. Therefore, the SpO2 value of the subject can be calculated by using the ratio between the intensity of the red light received by the light receiver 19 and the intensity of the infrared light received by the light receiver 19.

[0036] In addition, the display device 2 includes a sensor interface 23, a controller 24, a storage device 25, a network interface 26, an input operation section 27, a display section 28, a GPS (Global Positioning System) 29, and a power supply section 30. These components except the power supply section 30 are communicably connected to each other through a bus 38.

[0037] The sensor interface 23 is communicably connected to the vital sign information sensor 1. The sensor interface 23 includes a reader 32, a drive circuit 33, an analog processor 36, and an AD converter 37. The reader 32 is configured to acquire URL information stored in the memory 17 when the vital sign information sensor 1 is communicably connected to the display device 2. In other words, the URL information is transmitted from the memory 17 to the reader 32. The drive circuit 33 is configured to control the drive current (pulse current) supplied to the light emitter 18 based on the control signal output from the controller 24. For example, the drive circuit 33 is configured to control the time when the pulse current is supplied to the red light LED and the time when the pulse current is supplied to the infrared light LED.

[0038] The analog processor 36 is configured to amplify the pulse wave signal (electrical signal after photoelectric conversion) output from the optical receiver 19 and filter out noise components (e.g., high-frequency components) of the amplified pulse wave signal. The AD converter 37 is configured to convert the pulse wave signal (analog signal) output from the analog processor 36 into a digital signal based on a control signal output from the controller 24.

[0039] The controller 24 has a processor and a memory. The processor includes at least one of a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), and an MPU (Micro Processing Unit). The memory includes a RAM (Random Access Memory) and a ROM. The processor may be configured to develop a program specified from various programs embedded in the storage device 25 or the ROM on the RAM, and to perform various processes in cooperation with the RAM.

[0040] The controller 24 is configured to control various operations of the display device 2. In addition, the controller 24 is capable of receiving a digital signal (hereinafter referred to as a digital signal) of a pulse wave signal from the AD converter 37, and acquiring pulse wave data in which the digital signal and time information are associated with each other by using a timer function of the processor. The pulse wave data has information about the intensity of light received by the light receiver 19 and time information. The pulse wave data may include pulse wave data associated with red light and pulse wave data associated with infrared light. The pulse wave data may be stored in the RAM or the storage device 25.

[0041] In addition, the controller 24 can generate SpO2 value data indicating time changes in the SpO2 value and / or pulse rate data indicating time changes in the pulse rate based on the generated pulse wave data. The controller 24 can generate SpO2 value data based on the pulse wave data associated with the red light and the pulse wave data associated with the infrared light. Thus, the controller 24 can acquire the pulse wave data, the SpO2 value data, and / or the pulse rate data based on the digital signal output from the AD converter 37.

[0042] The storage device 25 is, for example, a storage device such as an HDD (hard disk drive), an SSD (solid state drive), a flash memory, etc. The storage device 25 is configured to store programs or various data. For example, pulse wave data, SpO2 value data, and / or pulse rate data may be stored in the storage device 25.

[0043] The network interface 26 is configured to connect the display device 2 to the communication network 3. Specifically, the network interface 26 may include various wired connection terminals for communicating with the WEB server 4 through the communication network 3. In addition, the network interface 26 may include various processing circuits and antennas for wirelessly connecting to an access point. The wireless communication standard between the display device 2 and the access point may be, for example, Wi-Fi (registered trademark), Bluetooth (registered trademark), ZigBee (registered trademark), or LPWA.

[0044] The display unit 28 may be a display device such as a liquid crystal display or an organic EL display, or may be a display device such as a transmissive or non-transmissive head-mounted display mounted on the operator's head. In addition, the display unit 28 may be a projection device that projects a video on a screen. The input operation unit 27 is configured to accept an input operation of a medical worker operating the display device 2, and generate a command signal corresponding to the input operation. The input operation unit 27 is, for example, a touch panel superimposed on the display unit 28, an operation button attached to a housing, a mouse and / or a keyboard, etc. After the command signal generated by the input operation unit 27 is transmitted to the controller 24 via the bus 38, the controller 24 performs a predetermined operation according to the transmitted command signal. The GPS 29 is configured to obtain position information (longitude, latitude) representing the current position of the display device 2. The power supply unit 30 is configured to supply power to each element of the display device 2.

[0045] Next, refer to Figure 3 An example of a method of visually presenting information related to the operation manual of the vital sign information sensor 1 (an example of information related to the vital sign information sensor 1 ) to a medical worker is described. Figure 3 1 is a flowchart for explaining an example of a method of visually presenting information related to the operation manual of the vital sign information sensor 1 to a medical worker.

[0046] exist Figure 3 In step S1 shown, the controller 24 determines whether the vital sign information sensor 1 has been physically connected to the display device 2. In particular, the controller 24 determines whether the connector 16 of the vital sign information sensor 1 has been inserted into the connector insertion portion 21 of the display device 2. When the determination result of step S1 is no, the controller 24 performs the determination process of step S1 again.

[0047] On the other hand, when the determination result of step S1 is yes, the controller 24 establishes communication with the vital sign information sensor 1 (step S2). For example, in order to establish communication with the vital sign information sensor 1, the controller 24 determines whether the connector 16 of the vital sign information sensor 1 physically connected to the display device 2 is a connector of another medical device for acquiring vital sign information. Specifically, after the controller 24 in the display device 2 has acquired information representing the vital sign information sensor 1 from the memory 17, the controller 24 may refer to the acquired information to determine whether the information represents the vital sign information sensor 1 or another medical device. When it is determined that the vital sign information sensor 1 is a pulse oximeter, the controller 24 may establish communication with the vital sign information sensor 1. On the other hand, when it is determined that the vital sign information sensor 1 is not a pulse oximeter, the controller 24 may refuse communication with the vital sign information sensor 1.

[0048] Next, the controller 24 obtains URL information from the memory 17 through the reader 32, and the URL information can obtain access to the electronic content provided by the WEB server 4 (step S3). In addition, in the processing in and after step S3, the controller 24 generates pulse wave data, SpO2 value data and / or pulse rate data based on the pulse wave signal after having obtained the pulse wave signal from the vital sign information sensor 1 (especially the light receiver 19) in real time through the sensor interface 23. The controller 24 displays a trend graph of the pulse wave data, etc. on the display unit 28. The trend graph displayed on the display unit 28 can be updated in real time.

[0049] Next, in step S4, the controller 24 refers to the URL information obtained from the memory 17, thereby obtaining electronic content including information related to the operation manual of the vital sign information sensor 1 from the web server 4 provided on the communication network 3 through the network interface 26. To this end, the controller 24 first obtains the IP address of the web server 4 corresponding to the domain name of the URL information from the DNS server. Next, the controller 24 refers to the obtained IP address of the web server 4, thereby sending an access request for the electronic content to the web server 4. Next, the web server 4 sends the electronic content to the display device 2 according to the access request for the electronic content published from the display device 2.

[0050] Here, the electronic content is a concept including electronic files such as HTML files, PDF files, moving image files, etc. In addition, the information related to the operation manual of the vital sign information sensor 1 may be information indicating the operation manual of the vital sign information sensor 1, or may be information indicating a link to other electronic content indicating the operation manual (e.g., PDF file, etc.). In this regard, when the acquired electronic content includes information indicating a link to other electronic content indicating the operation manual, the medical worker specifies the link through the input operation unit 27, so that the display device 2 can acquire other electronic content indicating the operation manual from the WEB server 4.

[0051] Next, the controller 24 displays the electronic contents acquired from the WEB server 4 on the display section 28 by using the WEB browser (step S5 ). Thus, the information related to the operation manual of the vital sign information sensor 1 is visually provided to the medical worker through the display section 28 .

[0052] According to the present embodiment, when the vital sign information sensor 1 is communicably connected to the display device 2, the URL information is transmitted from the memory 17 to the display device 2. Then, the display device 2 can refer to the URL information to obtain electronic content including information indicating information related to the operation manual of the vital sign information sensor 1 from the WEB server 4 provided on the communication network 3. According to this, even a medical worker who has little experience in using the vital sign information sensor 1 can view the information related to the operation manual of the vital sign information sensor 1 through the display section 28 (particularly, a WEB browser) of the display device 2 without having to prepare a printed copy of the operation manual of the vital sign information sensor 1 in advance. Thus, it is possible to provide the vital sign information sensor 1, the display device 2, and the vital sign information display system 100 with improved ease of use.

[0053] In addition, the electronic contents acquired from the WEB server 4 may include information indicating the operation manual of the vital sign information sensor 1 written in multiple languages. For example, it is assumed here that the electronic contents include the operation manual of the vital sign information sensor 1 written in Japanese and the operation manual of the vital sign information sensor 1 written in Chinese. In this case, a Japanese medical worker can browse the operation manual of the vital sign information sensor 1 written in Japanese, and a Chinese medical worker can browse the operation manual of the vital sign information sensor 1 written in Chinese. Thus, any medical worker can browse the information related to the vital sign information sensor 1 in multiple languages ​​through the display device 2. According to this, the vital sign information sensor 1, the display device 2, and the vital sign information display system 100 with improved ease of use can be provided.

[0054] Next, refer to Figure 4Another example of a method of visually presenting information related to the operation manual of the vital sign information sensor 1 to a medical worker is described. Figure 4 1 is a flowchart for explaining another example of a method for visually presenting information related to the operation manual of the vital sign information sensor 1 to a medical worker. Figure 3 The method shown is different in that the URL information to be referred to is determined based on the position information of the display device 2 .

[0055] exist Figure 4 In step S10 shown, the controller 24 determines whether the vital sign information sensor 1 has been physically connected to the display device 2. When the determination result of step S10 is yes, the controller 24 establishes communication with the vital sign information sensor 1 (step S11). Next, the controller 24 obtains multiple URL information from the memory 17 through the reader 32 (step S12). Here, each URL information can obtain access to a corresponding electronic content. In addition, each electronic content includes information related to the operation manual of the vital sign information sensor 1 written in a corresponding language. For example, it is assumed here that the WEB server 4 has stored electronic contents A to C. In this case, here, the electronic content A includes the operation manual of the vital sign information sensor 1 written in Japanese. Electronic content B includes the operation manual of the vital sign information sensor 1 written in English. Electronic content C includes the operation manual of the vital sign information sensor 1 written in Chinese. In this case, URL information capable of obtaining access to electronic content A, URL information capable of obtaining access to electronic content B, and URL information capable of obtaining access to electronic content C may also be stored in the memory 17. In addition, each piece of URL information is associated with a corresponding official language. That is, each piece of URL information has metadata indicating the corresponding official language. For example, URL information capable of obtaining access to electronic content B has metadata indicating that English is the official language.

[0056] Next, the controller 24 obtains the location information of the display device 2 by using the GPS 29 (step S13). Then, the controller 24 selects a piece of URL information obtained from the memory 17 based on the obtained location information of the display device 2 (step S14). In this regard, the controller 24 specifies the official language used in the area (such as a country, etc.) where the display device 2 is currently located based on the location information of the display device 2. Next, the controller 24 refers to each piece of metadata for a plurality of URL information to select a piece of URL information associated with the specified official language from the plurality of URL information. For example, it is assumed that the display device 2 is currently located in the United States. In this case, the controller 24 specifies that the official language is English based on the location information of the display device 2. Next, the controller 24 refers to each piece of metadata for a plurality of URL information to select a piece of URL information associated with English from the plurality of URL information.

[0057] Next, the controller 24 refers to the selected URL information, thereby acquiring electronic content corresponding to the selected URL information from the WEB server 4 provided on the communication network 3 through the network interface 26 (step S15). In other words, the controller 24 acquires electronic content including information associated with the operation manual of the vital sign information sensor 1 written in the official language corresponding to the position information of the display device 2 from the WEB server 4. For example, the controller 24 refers to the URL information associated with English, thereby acquiring electronic content including information related to the operation manual written in English.

[0058] Then, the controller 24 displays the electronic contents acquired from the WEB server 4 on the display unit 28 by using the WEB browser (step S16). Thus, the relevant information of the operation manual of the vital sign information sensor 1 written in the official language corresponding to the position information of the display device 2 is visually presented to the medical worker through the display unit 28.

[0059] According to the present embodiment, after a piece of URL information has been selected based on the position information of the display device 2, the electronic content corresponding to the selected piece of URL information is acquired. Thus, the medical worker can view the relevant information of the operation manual of the vital sign information sensor 1 in the language related to the position information of the display device 2 through the display device 2. For example, it is assumed that the medical worker who operates the display device 2 is in the United States. In this case, the medical worker can view the operation manual written in English, the official language of the United States. Accordingly, the vital sign information sensor 1, the display device 2, and the vital sign information display system 100 with improved ease of use can be provided.

[0060] Incidentally, in this example, the controller 24 acquires the location information of the display device 2 by using the GPS 29. However, the controller 24 may acquire the location information of the display device 2 based on the IP address of the display device 2 instead of the GPS 29. In this case, the controller 24 can at least specify the region (e.g., country, etc.) where the display device is currently located based on the IP address of the display device 2. Accordingly, the controller 24 can specify the official language used in the region where the display device 2 is currently located.

[0061] In addition, in the present embodiment, as an example of information related to the vital sign information sensor 1, an example of a method for visually presenting information related to the operation manual of the vital sign information sensor 1 to a medical worker has been described. However, the present embodiment is not limited thereto. For example, the information related to the vital sign information sensor 1 may include at least one of the following information: i) information related to the operation manual of the vital sign information sensor 1; ii) information related to the specifications of the vital sign information sensor 1; iii) information related to the brochure of the vital sign information sensor 1; and iv) information related to the subject to which the vital sign information sensor 1 is attached. In this case, the electronic content acquired from the WEB server 4 may include at least one of the aforementioned information i) to iv).

[0062] In addition, in the description of the present embodiment, the display device 2 acquires the URL information from the memory 17 of the vital sign information sensor 1 after establishing communication with the vital sign information sensor 1. However, the present embodiment is not limited thereto. For example, the URL information may be stored in the memory of the controller 24 or in the storage device 25. In this case, after establishing communication with the vital sign information sensor 1, the controller 24 may refer to the URL information stored in the memory of the controller 24 or in the storage device 25, so that the controller 24 can acquire electronic content from the WEB server 4. In addition, the controller 24 may select a piece of URL information stored in the memory of the controller 24 or in the storage device 25 based on the position information of the display device 2 after acquiring the position information of the display device 2.

[0063] In addition, the vital sign information sensor 1 has been described as an example of the vital sign information sensor in the present embodiment. However, the type of the vital sign information sensor is not limited to the pulse oximeter. For example, instead of the pulse oximeter, an electrocardiogram (ECG) sensor that acquires electrocardiogram information of the subject, a CO2 sensor, a blood pressure measurement cuff, an electroencephalogram electrode, a body temperature measurement probe, etc. may be used as the vital sign information sensor. In addition, each such vital sign information sensor may be a non-contact sensor that does not need to be installed on the subject.

[0064] Although the present invention has been described above, the technical scope of the present invention should not be interpreted restrictively by the description of the present embodiment. It should be understood by those skilled in the art that the present embodiment is only exemplary, and various changes can be made to the embodiment within the scope of the claimed invention. The technical scope of the present invention should be determined based on the scope of the claimed invention and the scope of its equivalents.
