Description

  The present invention relates to a remote patient support system.

  The patient can receive medical support such as treatment suitable for symptoms in a medical institution. In contrast, a patient who is spatially or temporally remote from doctors, nurses, etc. takes time to go to a medical institution, and it takes time for doctors etc. to rush from the medical institution. Many proposals have been made for medical support for such remote patients.

  For example, in Patent Document 1, a medical device connected to a network is operated, and a remote patient is examined at the same level as a doctor's office, and the entire process is stored in a database as diagnostic information. It is disclosed to send it to other contracted doctors via a network. The diagnostic information includes a face and other local stereoscopic images, a moving image of an ultrasonic diagnostic apparatus, an electrocardiogram, and the like.

  In Patent Document 2, as a medical assistance system, a patient image obtained by imaging a patient with a camera at the time of inputting reception information is attached, and skin color evaluation information and patient facial expression evaluation information are also attached, and these are stored in a hospital database. Accumulation is disclosed.

Patent Document 3 discloses that objective data for a patient is collected by a bedside monitor or a vital sign monitor, subjective data for the patient is collected by an imager, and these are used as electronic medical records. Objective data includes the patient's pulse, blood pressure, body temperature, blood glucose level, etCO ₂ (end respiratory carbon dioxide concentration), spO ₂ (arterial oxygen saturation), and the subjective data includes the patient's rash. , Information on trauma or bandage, facial pallor or flushing, painful facial expression, and the like.

  In relation to the present invention, as a communication system for ensuring the security of privacy information, Patent Document 4 discloses a mail transmission method using a next generation network system (NGN).

  Continued monitoring of the state of the patient by the imaging device in order to diagnose the condition of the patient in a remote place is a heavy burden on medical staff such as doctors. By collecting patient's biological information with a bedside monitor or vital sign monitor, automatically judging abnormalities and automatically notifying them, the burden on the doctors is reduced, but it is difficult to fully automate the detection of abnormalities It is. Therefore, it is preferable to notify a doctor or the like when there is a possibility of failure even in a fail-safe manner, but even in that case, the burden on the doctor or the like increases. Therefore, it is desired to ensure quick medical support even in remote locations.

  Since information about the patient's condition belongs to personal information, security is ensured so that a third party cannot access even in a medical institution. For example, even when information regarding the condition of a patient at a remote place is transmitted to a medical supporter using a network to provide appropriate support, it is desired to ensure security equivalent to that in a medical institution. Therefore, it is desired to ensure prompt medical support even in remote locations while ensuring appropriate security to protect the personal information of patients in remote locations.

  In the remote patient support system according to the present invention, a patient room terminal provided in a patient room remote from a medical institution and a plurality of support terminal used by each of a plurality of pre-registered medical support persons are determined in advance. A network connected by a communication method that satisfies a predetermined security standard, a patient support control device connected to the network, and a patient status data connected to the patient support control device and transmitted from a patient room terminal in association with time A patient data storage unit, and the patient room terminal is connected to an imaging device that images the patient state in the patient room and a plurality of sensor devices that detect the patient state in the patient room, and The patient support control apparatus includes a transmission unit that transmits captured image data and sensor data from a plurality of sensor apparatuses via a network. Determining whether or not the patient is in an emergency state using a predetermined emergency state determination threshold for at least one of the captured image data and the plurality of sensor data transmitted from the patient room terminal via the workpiece; When it is determined that the patient is in an emergency state, an emergency signal is simultaneously transmitted to all of the plurality of supporter terminals via the network.

  According to the above configuration, the patient room terminal and the plurality of supporter terminals are connected by a communication method that satisfies a predetermined security standard. This ensures appropriate security for protecting the patient's personal information at a remote location. In addition, when it is determined that the patient's state in the patient room is an emergency state, an emergency signal is simultaneously transmitted to all of the plurality of support terminals via the network. Compared to the above, the possibility that the medical supporter is aware of the emergency state of the remote patient is improved. This ensures prompt medical support for a patient in an emergency state even at a remote location.

  In the remote patient support system according to the present invention, a communication method satisfying a predetermined security standard assigns a line identification ID to all patient room terminals and all support terminal connected to the network, Using the line identification ID of the terminal and the line identification ID of the receiving terminal, a communication path is established between the two, and the line identification ID of the transmission source terminal is set in the captured image data and sensor data transmitted from the patient room terminal. It is preferable that the communication system be attached with a line identification ID of a supporter terminal as a transmission destination.

  According to the above configuration, the patient room terminal and the plurality of supporter terminals are connected via the network by a communication method using a line identification ID uniquely assigned to the user terminal. This communication method can use NGN described in Patent Document 4. According to this communication method, since impersonation reception by a third party is impossible, security of personal information of a patient at a remote place is ensured.

  In the remote patient support system according to the present invention, the patient support control device searches the patient data storage unit and transmits the emergency signal when receiving a request for transmitting the patient status data from the supporter terminal that has received the emergency signal. It is preferable to transmit patient data of a predetermined storage time set in advance with reference to the point in time to the supporter terminal of the transmission request source.

  According to the above configuration, the medical supporter can receive the patient data for a predetermined storage time based on the transmission time point of the emergency signal, so that the remote place in the emergency state can be received rather than based on the patient data at one time point. Medical support for patients will be accurate.

  In the remote patient support system according to the present invention, the registered medical support personnel are not only qualified physicians but also qualified nurses at home, qualified caregivers, qualified public health nurses, qualified physical therapists, occupational therapy It is preferable to be a qualified technician and a paramedic.

  According to the above configuration, an emergency signal is transmitted to a plurality of qualified nurses at home who have a higher degree of freedom than doctors in a medical institution. Increases the likelihood that a person will be aware of an emergency situation in a remote patient. Medical supporters at home can respond to emergency signals using each gap time. If there are multiple medical supporters at home, use the gap time of many people in a wide range of times. Correspondence becomes possible. In this way, if home medical supporters are connected via a network, rapid and appropriate medical support is expected beyond spatial remote and temporal remote.

  According to the remote patient support system according to the present invention, it is possible to ensure appropriate security for protecting the personal information of the patient at a remote location, and to ensure prompt medical support even at a remote location.

  Embodiments according to the present invention will be described below in detail with reference to the drawings. In the following, a patient room is a room of a patient's home that is geographically remote from a hospital that is a medical institution, but this is an illustrative example. Even if the patient room is not geographically remote from the medical institution, the doctor may not be resident and may be located in a remote place that requires a certain amount of time to reach the doctor. For example, it may be a patient room where a doctor is not resident, such as a room in a hospital at night or a health room in the workplace. The supporter room is a room of a medical supporter's home registered in advance, but this is an illustrative example. In addition to this, it may be a room of a support base where a medical supporter registered in advance resides. For example, it may be an emergency reception room of a support medical institution registered in advance.

  In the following, a case where there are three patient room terminals and four supporter terminals will be described, but this is an example for explanation, and other numbers may be used. For example, there may be one patient room terminal. Even in that case, the number of supporter terminals is plural. The captured image data, sensor data, and the like described below are examples for explanation, and can be appropriately changed according to the specifications of the remote patient support system.

  FIG. 1 is a configuration diagram of a remote patient support system 10. The remote patient support system 10 includes a network 40 to which a plurality of patient room terminals 12a, 12b, and 12c, a plurality of supporter terminals 14a, 14b, 14c, and 14d and a hospital 16 that is a medical institution are connected. Furthermore, a patient support control device 32 connected to the network 40 and a patient data storage unit 33 connected to the patient support control device 32 are included. The remote patient support system 10 is a system that can perform appropriate medical support by transmitting information on the status of the remote patients 22a, 22b, and 22c to the medical supporters 26a and 26c and the hospital 16 using the network 40.

  The patient room terminals 12a, 12b, and 12c are terminal devices that are provided in the patient rooms 20a, 20b, and 20c, respectively, and have a data transmission / reception function. The patient room terminals 12a, 12b, and 12c transmit data related to the states of the patients 22a, 22b, and 22c in the patient rooms 20a, 20b, and 20c to the outside through the network 40 using the transmission function. Further, for example, response signals from the supporter terminals 14a, 14b, 14c, and 14d are received via the network 40 by the reception function.

  As a configuration example of the three patient rooms 20a, 20b, and 20c, the case of the patient room 20a is shown in FIG. This is an example, and the configurations of the other patient rooms 20b and 20c are appropriately changed according to the medical conditions of the patients 22b and 22c.

The patient room 20a is a room in the patient's home that is remote from the hospital 16 that is a medical institution. A bed 50 is disposed in the patient room 20a. In the example of FIG. 2, the patient 22a is lying on the bed 50 in a resting state. The patient room 20a includes imaging devices 52L, 52R, and 52C, patient motion sensors 54, floor sensors 56L and 56R, a handset 58 including a microphone, a heart rate sensor 60, a thermometer 62, a sphygmomanometer 63, a blood glucose level sensor 64, and spO. _Two sensors 65 and the like are arranged. Further, a telephone 66, a response display lamp 68 indicating the correspondence of the medical supporter, and an ID card reader 70 are arranged. These are connected to the patient room terminal 12a, respectively.

  The imaging devices 52L, 52R, and 52C are cameras that image the state of the patient 22a in the patient room 20a from three directions. The imaging devices 52L and 52R are provided on the ceiling side of the patient room 20a, and image an area including the bed 50 and the floor sensors 56L and 56R from the left side and the right side of the patient 22a. The imaging device 52C is arranged on the head side of the bed 50 so that the facial expression, skin color, etc. of the patient 22a on the bed 50 can be imaged. The captured image data captured by the imaging devices 52L, 52R, and 52C is transmitted to the patient room terminal 12a via an appropriate signal line. The patient room terminal 12 a converts the transmitted captured image data into a data format suitable for data transmission in the network 40. An appropriate color camera is used as the imaging devices 52L, 52R, and 52C. Apart from the imaging device 52C, if necessary, an infrared camera may be arranged on the head side of the bed 50 to detect the temperature of the patient 22a in a non-contact manner.

  The patient motion sensor 54 is a wide plate-shaped sensor that has an area from the shoulder to the waist of the body of the patient 22 a lying on the bed 50 and is disposed on the bed 50. A plurality of pressure sensors are arranged in the patient motion sensor 54 at appropriate intervals within a wide plate-shaped range. Data detected by the patient motion sensor 54 is transmitted to the patient room terminal 12a via an appropriate signal line. The patient room terminal 12 a obtains the weight distribution data on the patient motion sensor 54 for the patient 22 a from the detection data of the patient motion sensor 54, and converts it into a data format suitable for data transmission in the network 40.

  Since the weight distribution state on the patient motion sensor 54 of the patient 22a changes depending on the motion of the patient 22a, the motion of the patient 22a on the bed 50 can be determined based on the detection data of the patient motion sensor 54. For example, it can be determined whether the person is calmly lying on the bed 50, is violently convulsed, is about to fall from the bed 50, is separated from the bed 50, or the like. The means for calculating the weight distribution state of the patient 22a on the patient motion sensor 54 from the detection data of the plurality of pressure sensors is provided in the patient room terminal 12a, but is included in a part of the patient motion sensor 54 instead. Also good.

  The floor sensors 56L and 56R are wide plate sensors laid on the left and right floors of the bed 50, respectively. Similar to the patient motion sensor 54, the floor sensors 56L and 56R are provided with a plurality of pressure sensors at appropriate intervals within a wide plate shape. The detection data of the floor sensors 56L and 56R is transmitted to the patient room terminal 12a via an appropriate signal line. The patient room terminal 12a obtains weight distribution data on the floor sensors 56L and 56R for the patient 22a from the detection data of the floor sensors 56L and 56R, and converts this to a data format suitable for data transmission in the network 40.

  Since the weight distribution state on the floor sensors 56L and 56R of the patient 22a changes depending on the movement of the patient 22a, the movement and the like of the patient 22a on the floor can be determined based on the detection data of the floor sensors 56L and 56R. For example, it is possible to determine whether the patient is normally walking on the floor, has fallen from the bed 50, is in a floor shape, is not moving at all, or is in a state where there is no patient 22a on the floor. A means for calculating the weight distribution state of the patient 22a on the floor sensors 56L and 56R from the detection values of the plurality of pressure sensors is provided in the patient room terminal 12a, but instead is included in a part of the patient motion sensor 54. May be.

  The handset 58 is a device that is provided on the head side of the bed 50 and includes a microphone and a speaker. The handset 58 detects the breathing sound and voice of the patient 22a using the microphone. The respiratory sound data detected by the microphone is transmitted to the patient room terminal 12a via an appropriate signal line. The patient room terminal 12a obtains the number of breaths per unit time of the patient 22a from the breathing sound data of the microphone, and converts this to a data format suitable for data transmission in the network 40.

  Further, when the handset 58 is connected to the supporter terminal 14a and the like via the patient room terminal 12a and the network 40, a dialogue can be made between the patient 22a and the medical supporter 26a and the like using a microphone and a speaker. it can. Although the same conversation can be made with the telephone 66, the handset 58 is provided on the head side of the bed 50, so there is no need to hold the handset with the hand like the telephone 66, and the conversation can be performed in a hands-free state. it can.

  The heart rate sensor 60 is a sensor that is attached to the chest of the patient 22a and detects a heart rate that is a pulsation of the heart of the patient 22a. The detection data of the heart rate sensor 60 is transmitted to the patient room terminal 12a via an appropriate signal line. The patient room terminal 12a obtains the heart rate per unit time of the patient 22a from the detection data of the heart rate sensor 60, and converts this to a data format suitable for data transmission in the network 40.

The thermometer 62, the sphygmomanometer 63, the blood glucose level sensor 64, and the spO ₂ sensor 65 are examples of various biological state sensors. Unlike the heart rate sensor 60 which is always attached to the patient 22a, these are sensor devices which are measured by the patient 22a itself or by a medical support person from the hospital 16 who visits the patient at an appropriately set measurement time. is there. Examples of biological state sensors other than these include, for example, etCO ₂ sensors, spO ₂ sensors, near infrared spectroscopy (NIRS) brain function measuring devices, and the like. In addition to the handset 58 that can detect breathing sounds, it may include a breathing sensor that is attached around the patient's nose and mouth. Detection data of various biological state sensors such as the thermometer 62, the blood pressure meter 63, the blood glucose level sensor 64, and the spO ₂ sensor 65 are transmitted to the patient room terminal 12a via an appropriate signal line. The patient room terminal 12 a converts these detection values into a data format suitable for data transmission in the network 40.

The various patient state sensors including the patient motion sensor 54, the floor sensors 56L and 56R, the handset 58 including the microphone, and the heart rate sensor 60 correspond to the body state sensor in a broad sense. Among these, the patient motion sensor 54, the floor sensors 56L and 56R, the handset 58 including the microphone, and the heart rate sensor 60 are emergency signal related devices together with the imaging devices 52L, 52R, and 52C, and in principle 24 hours a day. The patient condition is detected. The emergency signal-related device is a device that is used to determine whether or not the state of the patient 22a outputs an emergency signal that makes an emergency state that requires medical assistance urgently. Other biological state sensors such as the thermometer 62, the sphygmomanometer 63, the blood glucose level sensor 64, and the spO ₂ sensor 65 detect the patient state at a predetermined measurement time several times a day, for example. It is a periodic measurement device.

  The response display lamp 68 is a display lamp provided on the head side of the bed 50. For example, if an emergency signal is output for the patient 22a, a response signal indicating that one of the supporter terminals 14a, 14b, 14c, and 14d that has received the emergency signal responds. Is output, the response display lamp 68 is turned on. This gives a sense of security to the patient 22a in an emergency state.

  The ID card reader 70 is a card reader into which an IC card in which a line identification ID uniquely given to the patient room terminal 12a is written is inserted. When using an external memory such as a USB memory in which a line identification ID is written instead of the ID card, a memory interface is provided in the patient room terminal 12a, and the line identification ID in which the patient room terminal 12a is written in the external memory. Read. The line identification ID will be described later in connection with the network 40.

  The patient room terminal 12a is a patient room control device that receives captured image data detected by the imaging devices 52L, 52R, and 52C and sensor data detected by a biological sensor in a broad sense and performs appropriate signal processing. The patient room terminal 12 a includes a transmission / reception unit 72 that transmits and receives data to and from the network 40 under the control of the patient support control device 32. The transmission / reception unit 72 is provided with a network connector 73 such as a LAN connector. An example of signal processing performed by the patient room terminal 12a is detection time giving processing for adding the time detected by the data to the captured image data and sensor data. The patient room terminal 12a also performs data conversion processing for converting captured image data and sensor data into a data format suitable for data communication via the network 40.

  The above is the configuration of the patient room 20a. Returning again to FIG. 1, a plurality of supporter terminals 14 a, 14 b, 14 c, and 14 d are provided in the supporter rooms 24 a, 24 b, 24 c, and 24 d, and the network 40 is controlled under the control of the patient support control device 32. It is a terminal device having a data transmission / reception function via the network. The supporter terminals 14a, 14b, 14c, and 14d receive, via the network 40, data related to the states of the patients 22a, 22b, and 22c in the patient rooms 20a, 20b, and 20c by the reception function. In addition, for example, a response signal to an emergency signal, which will be described later, is transmitted to the patient room terminals 12a, 12b, and 12c via the network 40 using the transmission function.

  As the supporter terminals 14a, 14b, 14c, and 14d, computers suitable for data communication via a network are used. Preferably, a thin client type terminal without an internal storage device is better than a rich client type terminal with an internal storage device in order to ensure the security of data related to the patient condition. . More preferably, the data can be printed out. However, it is preferable that the printout is limited to a printout in which CONFIDENTIAL underprinting is performed on the entire surface of the data sheet. More preferably, data transfer restriction for prohibiting data transfer and copying may be performed.

  The supporter rooms 24a, 24b, 24c, and 24d are one room of a medical supporter's home registered in advance. In FIG. 1, the medical supporter 26a is present in the supporter room 24a, the medical supporter 26c is present in the supporter room 24c, and the medical supporter in the room happens to be in the other supporter rooms 24b and 24d. An example is shown. Examples of registered medical supporters include medical qualifications such as nurse qualification, caregiver qualification, public health nurse qualification, physical therapist qualification, occupational therapist qualification, paramedic qualification, etc. A qualified medical supporter who is a potential medical supporter who does not work full-time at a medical institution. It may be a potential medical supporter having a doctor qualification. A potential medical supporter is considered to have a higher degree of freedom in dealing with an emergency signal or the like than a medical supporter who is working full time at a medical institution such as a hospital. Therefore, for example, if an emergency signal is transmitted simultaneously to a plurality of pre-registered medical support personnel, it is expected that the supportability of medical support is improved as compared with the case where the emergency signal is transmitted to a specific person. .

  The hospital 16 is a medical institution that is convenient for rushing to the patient rooms 20a, 20b, and 20c. For example, the hospital 16 is a medical institution in which the respective doctors of the patients 22a, 22b, and 22c work. Since all patients 22a, 22b, and 22c are rarely the same attending physician, FIG. 1 shows one hospital 16 on behalf of a plurality of medical institutions. When the patients 22a, 22b, and 22c are to receive telemedicine support via the network 40, the hospital 16 in which the attending physicians of the patients 22a, 22b, and 22c work may be registered in advance and connected to the network 40. preferable. Depending on the circumstances, the attending physicians of the patients 22a, 22b, and 22c who are to receive telemedicine support may be physicians independent of the network 40. In the following, unless otherwise specified, the hospital 16 is a medical institution where the attending physicians of the patients 22a, 22b, and 22c work, and is registered in advance and connected to the network 40.

  The support center 30 performs remote control of data communication between the plurality of patient room terminals 12a, 12b, and 12c, the plurality of supporter terminals 14a, 14b, 14c, and 14d, and the hospital 16 that is a medical institution. This is a core office that provides medical support for local patients 22a, 22b, and 22c. In the support center 30, a patient support control device 32 connected to the network 40 and a patient data storage unit 33 are arranged. The support center 30 may perform schedule management for a plurality of medical supporters 26 a and 26 c and the like via the network 40. The support center 30 is installed under the management of a remote patient support group. Examples of remote patient support organizations include university hospitals and hospitals such as emergency designated hospitals that are regional core medical institutions.

  The network 40 is a data communication in which a plurality of patient room terminals 12a, 12b, and 12c, a plurality of supporter terminals 14a, 14b, 14c, and 14d, a hospital 16 that is a medical institution, and a patient support control device 32 are connected. It is a network. The network 40 uses a communication method that satisfies a predetermined security standard in order to transmit and receive data relating to a patient's state, which is personal information. As the predetermined security standard, a security standard that is compatible with security standards for transmission / reception of electronic medical records and the like in medical institutions such as hospitals is used among a plurality of security standards used internationally.

  As a network satisfying such a predetermined security standard, there are known an intranet connected by a dedicated line and a virtual private network (VPN) which is a technology for extending the intranet over a public network of the Internet. Then, the communication system by the next generation network system (Next Generation Network: NGN) currently disclosed by patent document 4 is used.

  In the network 40 using NGN, communication path control is performed by the patient support control device 32 as follows. That is, a line identification ID is assigned to all terminals connected to the network 40. In the example of FIG. 1, all terminals are patient room terminals 12a, 12b, and 12c, a plurality of supporter terminals 14a, 14b, 14c, and 14d, and terminals of doctors in a hospital 16 that is a medical institution. Then, using the line identification ID of the transmission side terminal and the line identification ID of the reception side terminal, a communication path between the two is established.

  Transmission of data from each of the patient room terminals 12a, 12b, and 12c is performed by attaching the line identification ID of the source patient room terminals 12a, 12b, and 12c to the captured image data and sensor data to be transmitted, and a supporter terminal as a transmission destination. 14a, 14b, 14c, 14d, and the line identification ID of the terminal of the attending physician in the hospital 16 are attached.

  Data from the patient room terminals 12a, 12b, and 12c is always subjected to line control via the patient support control device 32. The patient support control device 32 temporarily stores data from the patient room terminals 12a, 12b, and 12c in the patient data storage unit 33, and performs necessary data processing and the like. For example, when the state of the patient 22c in the patient room 20c is determined to be an emergency state (see FIG. 3 described later and FIG. 1 related thereto), the supporter terminals 14a, 14b, 14c to which the emergency signal is transmitted. , 14d and simultaneously transmitted to the doctor's terminal in the hospital 16. The emergency signal is assigned the line identification ID of the corresponding patient room terminal 12c as the transmission source, and all the support terminal 14a, 14b, 14c, 14d as the transmission destination and the line of the terminal of the attending physician in the hospital 16 An identification ID is attached.

  Further, in the above example, the communication between the patient room terminal 12c that is the source of the emergency signal and one supporter terminal 14c (see FIG. 3 described later and FIG. 1 related thereto) is transmitted to the data to be transmitted. This is performed by attaching the original line identification ID and the destination line identification ID. For example, the request signal of the data related to the patient state from the supporter terminal 14c attaches the line identification ID of the supporter terminal 14c as the transmission source to the request signal, and sets the line identification ID of the patient room terminal 12c as the transmission destination. Attached. Data from the supporter terminal 14 c is always subjected to line control via the patient support control device 32. The patient support control device 32 reads data related to the patient state corresponding to the request signal from the supporter terminal 14 c from the patient data storage unit 33. The data related to the read patient state is given the line identification ID of the patient room terminal 12c as the transmission source, the line identification ID of the supporter terminal 14c as the transmission destination, and then the supporter terminal 14c. Sent.

  As described above, in the NGN, under the communication path control of the patient support control device 32, the IP address that is the line identification ID is used. Since the IP address is uniquely assigned to each terminal, it is impossible for a third party to receive spoofing, thereby ensuring the security of transmission of patient status data as personal information. In a communication method using an intranet or VPN other than the NGN communication method, communication path control of the network 40 is performed using a registered mail address or the like under the patient support control device 32 instead of the line identification ID.

  The patient support control device 32 is a control device that performs communication path control of the network 40, and here, in particular, controls overall data communication for medical support of a remote patient. As the patient support control device 32, a computer suitable for data transmission / reception control via the network 40 is used.

  The patient support control device 32 has an input unit 31 and can input a line identification ID, a determination period related to a patient data sheet (see FIG. 4) described later, measurement time, setting and changing various threshold values, and the like. The patient support control device 32 includes a communication path control unit 34 that performs communication path control regarding the network 40. Furthermore, it has the emergency signal transmission part 36 which transmits an emergency signal based on the data regarding the patient state transmitted from patient room terminal 12a, 12b, 12c. In addition, it has a patient status data transmitting unit 38 that transmits data related to patient status data in response to a transmission request from the support doctor terminals 14a, 14b, 14c, 14d and the terminal of the attending physician in the hospital 16. These functions are realized by the patient support control device 32 executing software. Specifically, this is realized by the patient support control device 32 executing a remote patient support program. A part of the function may be realized by hardware.

  The patient data storage unit 33 connected to the patient support control device 32 is a storage device that stores data relating to the patient state in association with time.

  The operation and the like of the above configuration will be described in more detail with reference to FIG. FIG. 3 is a flowchart showing a remote patient support procedure in the remote patient support system 10. Each procedure corresponds to each processing procedure of the remote patient support program executed by the patient support control device 32.

  The patient support control device 32 gives a line identification ID to each terminal connected to the network 40. This processing procedure is executed by the function of the communication path control unit 34 of the patient support control device 32. The patient support control device 32 collects data related to the patient condition (S10). Specifically, since the captured image data and the sensor data are transmitted from each of the patient room terminals 12a, 12b, and 12c via the network 40, the patient support control device 32 receives them and temporarily Store in the patient data storage unit 33. As for the data transmission, the line identification ID of the transmission source patient room terminals 12a, 12b, and 12c is attached to the transmitted data, and all the supporter terminals 14a, 14b, 14c, 14d, and This is performed by attaching the line identification ID of the terminal of the attending physician at the hospital 16.

  The patient support control device 32 creates a patient data sheet 80 at a predetermined creation cycle for the transmitted data regarding the patient state, and based on the created patient data sheet 80, the state of each patient 22a, 22b, 22c It is judged whether it is an emergency state about (S12).

  FIG. 4 shows an example of the patient data sheet 80. The patient data sheet 80 for the patient 22c in the patient room 20c will be described below. In the patient data sheet 80, a bibliographic item column 82 describes a title, a creation date and a creation time, and a patient ID for the patient 22c. Clicking on the “patient detailed information” button field, when this is clicked, the name, gender, age, main medical history, address of the patient room 20c, telephone number, telephone number for emergency contact, hospital 16 where the doctor is located The name and phone number, the name of the attending physician, etc. are displayed. When the medical institution where the attending physician of the patient 22c is not connected to the network 40, the name and telephone number of the attending physician and the name of the attending physician are displayed.

  The emergency signal data column 84 is a column in which data used to determine whether or not the patient 22c is in an emergency state is described. The periodic measurement data column 86 is a column in which data of various sensors periodically measured for the patient 22c is described.

  The emergency signal mark 88 in the emergency signal data column 84 is a mark column that blinks when it is determined that the patient 22c is in an emergency state. The time column 90 is a column of elapsed time indicated in units of determination cycles for determining whether or not an emergency state exists. Here, the determination cycle is 1 minute, the time of the determination cycle in which the patient data sheet 80 is created is “present”, and the time traced back from “current” is shown every minute. The “left camera” column is a column indicating the state of the patient 22c by the imaging device 52L, the “right camera” column is a column indicating the state of the patient 22c by the imaging device 52R, and the “face camera” column is imaging. It is a column showing the face state of the patient 22c by the device 52C. The “moving / moving” column is a column indicating the moving state of the patient 22 c by the patient moving sensor 54. The “microphone” column is a column indicating the state of breathing sound and the like of the patient 22c by the handset 58. The “Heartbeat” column is a column indicating the state of the heartbeat of the patient 22c by the heartbeat sensor 60. The imaging devices 52L, 52R, and 52C, the patient motion sensor 54, the handset 58, and the heart rate sensor 60 are emergency signal related devices.

    The frames displayed as “Left camera”, “Right camera”, and “Face camera” are buttons, and when clicked, the captured image data goes back from “Current” and sequentially in moving image data. Is displayed.

  The six data columns relating to the state of the patient 22c in the emergency signal data column 84 indicate whether or not the state of each patient 22c is abnormal based on a predetermined threshold. In FIG. 4, each normal threshold range is indicated by Dth1 to Dth6. If the state of the patient 22c is within this normal threshold range, it is determined that there is no abnormality, and if it exceeds this normal threshold range, it is determined that there is an abnormality.

  The normal threshold ranges Dth1, Dth2, and Dth3 for the “left camera”, “right camera”, and “face camera” are image difference threshold values determined in advance for image differences between the captured image and the predetermined reference image. Determined based on range. As the predetermined reference image, a captured image in a state where the patient 22c is resting on the bed 50 is used. In order to identify the patient 22c for the captured image, the identification of the face portion is used. The identification of the face portion is performed by comparing the area of the skin-colored portion and the characteristic items such as eyes, mouth, nose, and ear with the face portion of the patient 22c in the reference image. As a result of comparison, when the face of the patient 22c cannot be specified on the bed 50 in the respective captured images of the “left camera”, “right camera”, and “face camera”, the position state of the patient 22c on the bed 50 is normal. It is assumed that the image difference threshold is exceeded in an abnormal state. At this time, it is determined that the normal threshold ranges Dth1, Dth2, and Dth3 are exceeded. When the skin color of the patient 22c specified by the captured image of the “face camera” is flushed or whiter than a predetermined color tone, it is determined that the face color is abnormal and exceeds the image difference threshold and exceeds the normal threshold range Dth3 .

  In the patient data sheet 80, the captured image data of the “left camera”, “right camera”, and “face camera” determined using the normal threshold ranges Dth1, Dth2, and Dth3 are not video communication data, but simply from moment to moment. It is used as sensor data for determining the patient condition of the patient. On the other hand, the moving image data that is displayed in sequence when clicking the frames labeled “Left Camera”, “Right Camera”, and “Face Camera” is not sensor data for determining patient status, but patient data. This is video communication data for displaying the motion of the body 22c as a video. As described above, the captured image data of the “left camera”, “right camera”, and “face camera” has two sides of sensor data and video communication data, and the patient data sheet 80 uses these two sides separately. Can be used.

  The normal threshold range Dth4 for “moving and moving” is within a predetermined abnormal threshold range for a difference between the weight distribution state on the patient moving and sensing sensor 54 based on the detection data of the patient moving and rest sensor 54 and a predetermined reference weight distribution state. Determined based on. As the predetermined reference weight distribution state, a weight distribution state in a state in which the patient 22c is lying on the bed 50 is used. When the difference between the weight distribution state transmitted from the patient room terminal 12c and the reference weight distribution state exceeds a predetermined abnormality threshold, it is assumed that the movement of the patient 22c on the bed 50 is abnormal and exceeds the movement abnormality threshold. Moreover, when the weight distribution state transmitted from the patient room terminal 12c fluctuates at a cycle shorter than a predetermined fluctuation cycle, “convulsions” may occur, and in this case also, the movement abnormality threshold is exceeded. And The predetermined fluctuation cycle is determined with respect to the number of changes in the weight distribution state for one minute from the previous determination cycle to the current determination cycle. For example, when there is a weight distribution variation of 10 times or more per minute, it is assumed that the abnormal movement threshold is exceeded. At these times, it is determined that the normal threshold range Dth4 is exceeded.

  The normal threshold range Dth5 for the “microphone” is within a predetermined abnormal threshold range with respect to the difference between the respiratory rate per unit time of the patient 22c based on the detection data of the microphone of the handset 58 and the predetermined reference respiratory rate. Determined based on. As the predetermined reference respiration frequency, a respiration frequency of 1 minute in a state where the patient 22c is lying on the bed 50 is used. Therefore, the respiratory rate of the patient 22c for one minute from the previous determination cycle to the current determination cycle is compared with the reference respiratory rate, and when exceeding the predetermined abnormal threshold range, the respiratory abnormal threshold is exceeded. In addition, when the breathing sound or voice of the patient 22c detected by the microphone exceeds the predetermined abnormal threshold range, the voice abnormal threshold is exceeded as an abnormally loud breathing sound or voice. When the respiratory abnormal threshold or the speech abnormal threshold is exceeded, it is determined that the normal threshold range Dth5 is exceeded.

  The normal threshold range Dth6 for “heart rate” is based on a range of abnormal threshold values that are predetermined for differences between a heart rate per unit time of the patient 22c based on detection data of the heart rate sensor 60 and a predetermined reference heart rate. Determined. As the predetermined reference heart rate, a one-minute heart rate in a state where the patient 22c is resting on the bed 50 is used. Therefore, the heart rate of the patient 22c for one minute from the previous determination cycle to the current determination cycle is compared with the reference heart rate, and when exceeding the predetermined abnormal threshold range, the heart rate sensor abnormal threshold is exceeded. At this time, it is determined that the normal threshold range Dth6 is exceeded.

  In the above description, whether or not the state of the patient 22c is abnormal uses the threshold determination of whether or not the normal threshold range Dth1 to Dth6 is exceeded. Instead, data feature amounts are extracted from captured image data and sensor detection data using known appropriate methods, threshold determination for the extracted feature amounts, identification function generation in the feature space, feature amount A determination criterion or the like may be set, and abnormality determination may be performed based on the determination reference.

The abnormal signal mark 92 in the periodic measurement data column 86 is a mark column that blinks when it is determined that the periodic measurement data of the patient 22c is in an abnormal state. The time column 94 is a column in which the time when the regular measurement is performed is described. An example of the time when the regular measurement is performed is 7 am or 7 pm, assuming that the regular measurement is performed twice a day. This is an exemplification, and is appropriately changed depending on the circumstances of the patient 22c and the like. The “body temperature” column is a column in which the body temperature detection value of the patient 22c by the thermometer 62 is described, and the “blood pressure” column is the maximum blood pressure value, minimum blood pressure value, and pulse rate of the patient 22c by the sphygmomanometer 63. It is a column. The “BGL” column is a column in which the blood glucose level detection value related to the blood glucose level of the patient 22 c by the blood glucose level sensor 64 is described, and the “spO ₂ ” column is the arterial blood oxygen of the patient 22 c by the spO ₂ sensor 65. It is a column in which the saturation detection value is described. When the abnormality signal mark 92 blinks, it is not an emergency state, but an abnormality has occurred in the biological state data of the patient 22c, so an abnormality signal different from the emergency signal is transmitted. The procedure may be performed according to the emergency signal.

  5 and 6 show two examples in which the patient 22c in the patient room 20c is determined to be in an emergency state. In each figure, (a) shows the contents of the patient data sheet 80 in the determination cycle in which the emergency signal mark 88 blinks, and (b) is a schematic diagram of the state of the patient 22c in the patient room 20c at that time.

  FIG. 5 shows a state where the patient 22c falls from the bed 50 and cannot move, but is held by the bed 50. FIG. Looking at the patient data sheet 80 at this time, the detection status of “face camera”, “right camera”, “moving and moving”, “microphone” exceeds the normal threshold range, and “left camera”, “heart rate” The detection state is within the normal threshold range. From this, it can be seen that the patient 22c is in the state of FIG. 5B in which the weight is partly on the bed 50 but not on the bed 50 but on the left side of the bed 50. In this state, it is determined that the patient 22c is in an emergency state, and the emergency signal mark 88 flashes.

  FIG. 6 shows a state in which the patient 22c is lying on the bed 50 but is convulsed. Looking at the patient data sheet 80 at this time, the detection states of “heart rate”, “face camera”, “moving and moving”, and “microphone” exceed the normal threshold range, and “left camera” and “right camera” The detection state is within the normal threshold range. From this, it can be seen that the patient 22c is lying on the bed 50, but the heartbeat and breathing are abnormal, and "convulsions" occur throughout the body, as shown in FIG. In this state, it is determined that the patient 22c is in an emergency state, and the emergency signal mark 88 flashes.

  As shown in the examples of FIGS. 5 and 6, the emergency state determination threshold for the state of the patient 22c is Dth1, Dth2, and Dth3, which are image difference thresholds for image differences between the captured image data and the reference image data. These are set based on sensor abnormality threshold values Dth4, Dth5, and Dth6 for sensor data of the biological state sensors related to a plurality of patient states. Regarding the determination as to whether or not it is an emergency state, the captured image data is used for detecting the state of the patient 22c in the same manner as the sensor data. Therefore, in the example of FIG. 5, two image difference threshold values and two sensors are used as the emergency state determination threshold values. A total of four abnormal thresholds are used. In the example of FIG. 6, a total of four emergency image determination threshold values, that is, one image difference threshold value and three sensor abnormality threshold values are used. In consideration of detecting the emergency state of the patient 22c as quickly as possible, it is preferable to use a predetermined emergency state determination threshold for at least one of the captured image data and the plurality of sensor data. That is, one of Dth1 to Dth6 is used as the emergency state determination threshold.

  When it is considered that there is a risk of erroneous determination if it is determined whether or not the patient 22c is in an emergency state based on only one data, it is possible to use two or more of Dth1 to Dth6 as the emergency state determination threshold. Good. In this case, at least one of Dth1 to Dth3 for the three captured image data and at least one of Dth4 to Dth6 for the plurality of sensor data may be used. Note that at least one of Dth4 to Dth6 for the plurality of sensor data includes at least Dth5 related to the handset 58 or the respiratory sound sensor for detecting the respiratory sound of the patient, and Dth6 related to the heart rate sensor 60 for detecting the heartbeat of the patient. One may be included. This is because when an abnormality occurs in the patient 22c, an abnormality usually occurs in the breathing sound or heartbeat.

  Returning to FIG. 3 again, in S12, it is determined whether or not the state of the patient 22c is an emergency state using the emergency state determination threshold. If the determination in S12 is negative, the process returns to S10 and collection of patient state data is repeated. If the determination in S12 is affirmative, simultaneous transmission of emergency signals is performed (S14). This processing procedure is executed by the function of the emergency signal transmission unit 36 of the patient support control device 32. In the examples of FIGS. 5 and 6, the state of the patient 22c is determined to be an emergency state based on the captured image data and sensor data transmitted from the patient room terminal 12c. The patient support control device 32 attaches the line identification ID of the patient room terminal 12c as a transmission source to the emergency signal image data 96 shown in FIG. 7, and all the supporter terminals 14a, 14b, 14c, 14d, And the line identification ID of the terminal of the attending doctor of the hospital 16 are simultaneously transmitted through the network 40 simultaneously.

  The emergency signal image data 96 includes two texts 98 and 99 relating to a response, a transmission button 100, a text indicating that “! Emergency signal! Has been sent”, a matter relating to the patient 22 c and a matter relating to the transmission source. including. The items related to the transmission source are items related to the transmission destination described in the emergency signal image data 96 in advance. When a reply is made by pressing the transmission button 100, the matters relating to the transmission destination described in advance are the matters relating to the transmission source pressing the transmission button 100 as they are.

  In FIG. 1, all the supporter terminals 14 a, 14 b, 14 c, and 14 d have received emergency signal image data 96 by a mark “!!!!”. Among the plurality of supporter rooms 24a, 24b, 24c, and 24d, the supporter rooms 24a and 24c have medical supporters 26a and 26c, and other than that, it happens that the medical supporter in the room is outside the room. I'm in. The emergency signal image data 96 is also transmitted to the hospital 16. However, since the attending doctor of the hospital 16 is often pursued in the hospital, the attending doctor of the hospital 16 will use the emergency signal image data 96 below. Suppose you haven't seen it yet.

  The medical supporters 26a and 26c are viewing the emergency signal image data 96 of the respective supporter terminals 14a and 14c. When neither of the two buttons 98 and 99 in the emergency signal image data 96 is clicked but the transmission button 100 is clicked, the medical support cannot be expected simply by looking at the emergency signal image data 96. Is not processed. Hereinafter, a case where the medical support person 26c clicks one of the two buttons 98 and 99 related to the response of the emergency signal image data 96 and clicks the transmission button 100 will be described. By clicking the send button 100, the clicked emergency signal image data becomes reply data, the line identification ID of the supporter terminal 14c as the transmission source is added to the reply data, and the patient room terminal 12c as the transmission destination. And transmitted via the network 40. Since the emergency signal image data 96 received by the supporter terminal 14c becomes reply data, the supporter terminal 14c that has received the emergency signal image data 96 is already described in the reply data as the transmission source information. .

  Upon receiving this reply data, the patient support control device 32 determines whether there is a request for sending patient status data (S16). Specifically, it is determined whether or not only the “Please send patient status data” button 98 is clicked. When the button 98 is not clicked and only the “corresponding” button 99 is clicked, S16 is denied. When S16 is denied, the communication path control is performed, and a signal “corresponding” is transmitted to the patient room terminal 12c which is the transmission destination. Upon receiving this, the patient room terminal 12c turns on the response display lamp 68 of the patient room 20c. This is expected to give a sense of security to the patient 22c in an emergency state.

  When the button 99 is clicked, the determination in S16 is affirmed, so that patient status data is transmitted (S18). This processing procedure is executed by the function of the patient state data transmission unit 38 of the patient support control device 32. Specifically, the patient data sheet 80 at the time of the determination cycle in which it is determined that the state of the patient 22c is an emergency state is transmitted. When the patient data sheet 80 is the patient data sheet 80 of FIG. 5, the line identification ID of the patient room terminal 12c as the transmission source is attached to the data of the patient data sheet 80, and the data of the supporter terminal 14c as the transmission destination. It is transmitted via the network 40 with a line identification ID.

  FIG. 8 shows the cover page image data 110 of the patient data sheet 80. The cover sheet image data 110 includes two buttons 112 and 113 relating to a response and a transmission button 114 together with a text “A patient data sheet will be attached”.

The medical supporter 26c confirms the abnormal value of the emergency signal related device based on the patient data sheet 80. By clicking the “left camera”, “right camera”, and “face camera” frames in the patient data sheet 80, the captured image data can be displayed retroactively from the “current” time, so that the change in the state of the patient 22c Can be confirmed. In the above example, the captured image data of the “left camera” is displayed retroactively from the “current” time, so that it can be seen how the patient 22c has moved from the bed 50 to the floor. Further, the captured image data of the “face camera” can be traced back to the time when the patient is on the bed 50 to know the facial expression and the like when the patient 22c is lying on the bed 50. Further, by looking at the time column 94 and the periodic measurement values of the thermometer 62, the sphygmomanometer 63, the blood glucose level sensor 64, and the spO ₂ sensor 65, the patient 22c at the time when the most recent periodic measurement was performed with respect to “current”. Can be judged.

  The medical supporter 26c grasps the state of the patient 22c based on the patient data sheet 80 and makes a determination on the emergency signal. As a result, when it is determined that there is an accidental abnormality detection and no special emergency support is required, click the button 112 “I want to talk to the patient” in the cover page image data 110, Click the send button 114. By clicking the send button 114, the clicked cover page image data 110 becomes reply data, and the reply data is attached with the line identification ID of the supporter terminal 14c as the transmission source, and the patient room terminal as the transmission destination. The line identification ID of 12c is attached and transmitted via the network 40. In this communication path control, the patient support control device 32 connects the supporter terminal 14 c and the handset 58 in the patient room 20 c via the network 40. Thereby, the medical supporter 26c can directly interact with the patient 22c via the handset 58. Therefore, the medical supporter 26c can ask the patient 22c, such as “How has an abnormality been detected? If you are confident that you are not in a particularly worrying situation through dialogue with the patient 22c, you will be told that you are safe. In this way, appropriate medical support can be provided to the patient 22c at a remote location.

  When the medical supporter 26c determines that emergency support is required based on the patient data sheet 80, the medical supporter 26c clicks the button 113 “I want to email the patient's attending physician” in the cover sheet image data 110 and sends it. Click the button 114. The emergency signal image data 96 is also transmitted to the attending physician of the hospital 16 where the patient's attending physician works. However, if the attending physician of the hospital 16 is busy with in-hospital correspondence, the emergency signal image data 96 may not be seen yet. There is sex. The medical supporter 26c clicks the button 113 in the cover sheet image data 110 saying “I want to email the patient's primary doctor”. The medical supporter 26c determines the condition of the patient 22c on behalf of the busy doctor in the hospital 16 and determines the result. This is to immediately inform the attending physician of the hospital 16. As a result, the burden on the busy doctor can be reduced.

  By clicking the transmission button 114, the clicked cover page image data 110 becomes reply data, and the reply data is given the line identification ID of the supporter terminal 14c as the transmission source, and the hospital 16 as the transmission destination. A line identification ID is attached and transmitted via the network 40. In this communication path control, the patient support control device 32 sets a mail transmission screen addressed to the mail address of the attending physician in the hospital 16 on the supporter terminal 14c. As a result, the medical supporter 26c sends an email requesting an emergency arrangement to the attending physician of the hospital 16, explaining the address of the patient room 20c, data summarizing the emergency state of the patient 22c, noticeable signs, etc. it can. In this mail transmission screen, a “reply” mode is set, and a reply from the attending physician to the medical supporter 26c can be made.

  Further, the “patient detailed information” button in the patient data sheet 80 is clicked to read the telephone number of the hospital 16 where the attending physician is located, and contact the hospital 16 using a public telephone line. The hospital 16 is informed that the detailed email has been sent to the attending physician, further explains the address of the patient room 20c, the emergency state of the patient 22c, etc., and requests emergency arrangements. Thus, the attending physician of the hospital 16 can recognize that the patient 22c is in an emergency state, and confirms the detailed patient data sheet 80 and the like based on the emergency signal image data 96 sent to him / her as necessary. Can make any necessary emergency arrangements.

  In addition to this, the medical supporter 26c clicks the button 112 in the cover sheet image data 110 indicating “send / receive speech by voice with the patient”, whereby the medical supporter 26c receives the patient 22c via the handset 58. Can interact directly. Therefore, the medical supporter 26c tells the patient 22c that he / she is relieved because “the abnormality was detected, so the doctor in charge was contacted and an immediate response was requested”. In this way, appropriate medical support can be provided to the patient 22c at a remote location.

  When the medical institution where the attending physician of the patient 22c is not connected to the network, even if the button 113 “I want to mail to the attending physician” of the cover sheet image data 110 is clicked, the “patient's attending physician” Is not connected to the network. " In this case, the “patient detailed information” button in the patient data sheet 80 is clicked, the telephone number of the medical institution where the attending physician is located is read, the public institution is used to contact the medical institution, and the patient room Explain the address of 20c, the emergency state of the patient 22c, etc., and request emergency arrangements. Thus, the attending physician of the patient 22c can recognize that the patient 22c is in an emergency state and can make necessary emergency arrangements.

  The attending physician at the hospital 16 reviews the emergency arrangement for the patient 22c in response to the communication from the medical supporter 26c, and when it is determined that it is necessary, arranges for an ambulance or processes such as rushing under the patient 22c. Do. After the emergency treatment is performed, “Thank you for contacting us using the“ Reply ”mode on the email sending screen set up between the medical supporter 26c and the attending physician. "I will report this because I have completed". Thereby, the medical support person 26c knows that the medical support for the patient 22c by the attending physician has been performed. In addition, an email requesting emergency arrangement for the patient 22c may be transmitted from the person other than the medical supporter 26c to the attending doctor of the hospital 16 via the network 40. Even in that case, the same reply can be made by using the “reply” mode on the mail transmission screen set between the medical supporter 26c and the attending physician.

  In addition, when neither of the two buttons 112 and 113 in the cover sheet image data 110 is clicked but the send button 114 is clicked, the medical support cannot be expected immediately simply because the patient data sheet 80 is received. Therefore, the subsequent processing is not performed.
