Abstract
Description
[Technical field]
[0001] The present disclosure relates to a medical load system and a central terminal used in the medical load system. [Background technology]
[0002] One type of medical stress system is cardiac rehabilitation (hereinafter "rehabilitation" may be abbreviated as "rehab"). Cardiac rehabilitation is performed, for example, through exercise therapy for patients with angina pectoris, patients after PCI (Percutaneous Coronary Intervention), and patients with heart failure, with the aim of extending life expectancy and improving exercise tolerance.
[0003] Cardiac rehabilitation is mainly performed in rehabilitation rooms set up exclusively for rehabilitation in hospitals and other facilities. Exercise stress devices such as medical treadmills and ergometers are installed in the rehabilitation rooms. Patients undergoing cardiac rehabilitation are fitted with electrocardiograms and blood pressure monitors. Medical professionals such as doctors, physical therapists, and nurses manage the operation of cardiac rehabilitation and evaluate the performance of cardiac rehabilitation based on the patient's biological information acquired by the electrocardiogram and blood pressure monitor.
[0004] Devices for managing rehabilitation exercise results are disclosed in, for example, Patent Documents 1 and 2.
[0005] Patent Document 1 proposes a rehabilitation management device that analyzes exercise information from rehabilitation exercises performed by patients and manages the overall history of the motor functions of multiple patients. Patent Document 2 proposes a rehabilitation support device that makes it easy to understand whether the evaluation values of many rehabilitation evaluation items are improving overall, are unchanged, or are getting worse by going back to a desired point in time.

[0006] [Patent Document 1] JP 2005-352686 A [Patent Document 2] JP 2010-108430 A Summary of the Invention [Problem to be solved by the invention]
[0007] When conducting cardiac rehabilitation, for example, a group is made up of eight patients, each of whom is assigned an exercise stress machine such as a treadmill or ergometer, and all eight patients undergo rehabilitation at the same time.
[0008] In recent years, cardiac rehabilitation support systems have also been moving towards wireless communication. This increases the flexibility of the system and makes it easier for medical professionals to manage cardiac rehabilitation.
[0009] However, when making a cardiac rehabilitation support system wireless, sufficient consideration has not been given to what kind of wireless system should be constructed.
[0010] In particular, in cardiac rehabilitation, as mentioned above, a large number of patients undergo rehabilitation at the same time, and it is expected that a large number of wireless terminals will be used, and sufficient consideration has not been given to how these should be wirelessly connected to enable medical professionals, who are the users, to carry out their work efficiently.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0016] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings.
[0017] <1. System configuration> 1 is a schematic diagram showing the overall configuration of a cardiac rehabilitation support system 10 according to an embodiment of the present disclosure. Cardiac rehabilitation differs from musculoskeletal rehabilitation in which rehabilitation is performed for each patient in turn (performed one-on-one between a medical professional and a patient), in that a medical professional can perform rehabilitation for multiple patients simultaneously while monitoring the biological information (e.g., ECG) and exercise records of multiple patients.
[0018] The cardiac rehabilitation support system 10 includes a tablet terminal 100. A plurality of individual units 20-1, 20-2 are connected to the tablet terminal 100. In the example of Fig. 1, two individual units 20-1, 20-2 are connected to the tablet terminal 100, but this is not limited thereto. For example, the number of individual units connected to the tablet terminal 100 may be one, or three or more.
[0019] In the example of Fig. 1, only one tablet terminal 100 is shown for the sake of simplicity, but the cardiac rehabilitation support system 10 may have a plurality (n) of tablet terminals 100. In the following description, a group consisting of one tablet terminal 100 and its subordinate individual units 20-1 and 20-2 will be referred to as a unit 101. Thus, the cardiac rehabilitation support system 10 generally has n unit units 101-1 to 101-n.
[0020] The cardiac rehabilitation support system 10 of this embodiment is assumed to have n=4, that is, four basic units 101. Therefore, the cardiac rehabilitation support system 10 has 2×4=8 individual units and can simultaneously perform cardiac rehabilitation for eight patients.
[0021] Each of the individual units 20-1 and 20-2 has a load device 21, a load controller 22, an input box 23, and a blood pressure monitor 24 as components.
[0022] As shown in the figure, the load device 21 is, for example, an ergometer. Alternatively, the load device 21 may be another device, such as a treadmill. The load device 21 operates based on a control signal from a load controller 22. Furthermore, information on the operating state of the load device 21, for example information on the number of revolutions of the pedals of the ergometer, is sent from the load device 21 to the load controller 22.
[0023] The input box 23 is a device that inputs biological information of a patient undergoing cardiac rehabilitation and transmits the biological information wirelessly. The input box 23 is housed, for example, in a dedicated bag accompanying the patient. The input box 23 inputs the ECG and SpO2 of the patient during or after rehabilitation.
[0024] Specifically, the input box 23 is connected to a lead wire connected to an electrode for ECG measurement worn by the patient. The input box 23 is also connected to a lead wire connected to a probe for SpO2 measurement worn by the patient. In this way, the input box 23 inputs an ECG signal and an SpO2 signal via a wire. The input box 23 converts the ECG signal and the SpO2 signal input via a wire into a digital signal and transmits it wirelessly to the tablet terminal 100. The tablet terminal 100 has a function of analyzing an ECG, and for example performs an arrhythmia analysis and displays the analysis result.
[0025] In this embodiment, the tablet terminal 100 and the input box 23 wirelessly communicate with each other using a communication method that complies with the BLE (Bluetooth Low Energy) standard. The tablet terminal 100 and the input box 23 are in a relationship in which the tablet terminal 100 is a central (parent device) and the input box 23 is a peripheral (child device).
[0026] It should be noted that the input box 23 differs from a medical telemeter in terms of the frequency band and communication method used. In this embodiment, by using the input box 23 that uses the Bluetooth (registered trademark) communication method, it is possible to easily connect to the tablet terminal 100 without the user having to perform a connection setting operation as in the case of a medical telemeter. In this embodiment, biological information such as ECG data, which has conventionally been sent to a management terminal by wire, is wirelessly transmitted to the tablet terminal 100 using the input box 23 that uses Bluetooth communication.
[0027] The sphygmomanometer 24 is a so-called automatic sphygmomanometer, and measures the blood pressure of a patient during or after cardiac rehabilitation. The sphygmomanometer 24 operates based on a control signal from the load controller 22. In addition, the blood pressure measurement result is sent from the sphygmomanometer 24 to the load controller 22. The sphygmomanometer 24 is placed on, for example, a cart.
[0028] In this embodiment, the blood pressure monitor 24 is a so-called R-wave synchronous automatic blood pressure monitor. A more detailed description will be given. The blood pressure monitor 24 measures blood pressure by the Liberaloch-Korotkoff method. The blood pressure monitor 24 inflates a cuff wrapped around the upper arm of the patient to a target pressure, and then depressurizes the cuff at a constant speed. The Korotkoff sounds generated during the depressurization process are detected by a microphone attached to the cuff. The cuff pressure when the Korotkoff sounds begin to be heard is detected as the systolic blood pressure, and the cuff pressure when the Korotkoff sounds disappear is detected as the diastolic blood pressure.
[0029] In cardiac rehabilitation, the patient exercises, which may result in noise being superimposed on the Korotkoff sounds, making it difficult to measure blood pressure. Therefore, the blood pressure monitor 24 sets an effective range for the Korotkoff sounds based on the position of the R wave, and removes the Korotkoff sounds that occur outside the effective range as noise.
[0030] Timing information of the R waves detected by the input box 23 or the tablet terminal 100 is input to the sphygmomanometer 24 via the access point (AP) 30 and the load controller 22, and the sphygmomanometer 24 uses this timing information of the R waves to remove Korotkoff sound noise and measure blood pressure.
[0031] Here, the load device 21 and the sphygmomanometer 24 are wired to the load controller 22 using an input / output interface conforming to the RS232C standard. The load device 21 and the sphygmomanometer 24 may be connected to the load controller 22 using an input / output interface conforming to another standard.
[0032] The cardiac rehabilitation support system 10 has an AP 30 of a wireless LAN (Local Area Network). The load controllers 22 of the individual units 20-1 and 20-2 and the tablet terminal 100 are wirelessly connected to the AP 30. In the embodiment, four individual units 101, that is, four tablet terminals 100 and eight load controllers 22 are wirelessly connected to the AP 30. Note that the wireless LAN in this specification may be read as Wi-Fi (registered trademark). Here, Wi-Fi is a communication technology conforming to the IEEE 802.11 standard, as is well known.
[0033] The AP 30 is also connected by wire to a monitoring terminal 200 and a management database terminal 300 via a hub 40 .
[0034] The tablet terminal 100 is used during cardiac rehabilitation by medical professionals such as doctors, physical therapists, and nurses who manage cardiac rehabilitation. The tablet terminal 100 has a display unit, an operation input unit, a calculation unit, and a wireless communication unit. The tablet terminal 100 is wirelessly connected to the input box 23 using Bluetooth wireless technology, and biological information from the input box 23 is sent to the tablet terminal 100 wirelessly using Bluetooth.
[0035] The monitoring terminal 200 is realized, for example, by installing dedicated software on a personal computer, and collectively displays information acquired by multiple (e.g., n=4) tablet terminals 100. This allows the monitoring terminal 200 to collectively display biological information of multiple (e.g., 8) patients undergoing cardiac rehabilitation. The monitoring terminal 200 can also send commands to the load device 21 and blood pressure monitor 24, etc., and can also send these commands to the tablet terminal 100.
[0036] The management database terminal 300 is realized, for example, by installing dedicated software on a personal computer, and stores and analyzes the biometric information from the tablet terminal 100. The management database terminal 300 also has a function for editing the biometric data, and can also provide comprehensive information.
[0037] For example, rehabilitation data for today can be compared with rehabilitation data from one month ago on the management database terminal 300. In addition, a printer (not shown) is connected to the management database terminal 300, making it possible to print reports using the printer.
[0038] Here, an outline of the operation of the cardiac rehabilitation support system 10 will be described.
[0039] When the medical staff operates the tablet terminal 100, a control signal corresponding to the operation is sent to the load controller 22, and the load of the load device 21 and the operation of the sphygmomanometer 24 are controlled.
[0040] The load controller 22 functions as a relay that converts data so that the format of data exchanged between the tablet terminal 100 and the load device 21 and the sphygmomanometer 24 is suitable for each interface. For example, the load controller 22 converts a control signal from the tablet terminal 100 into control data suitable for the interface (i.e., RS232C) of each of the load device 21 and the sphygmomanometer 24, and transmits it to each of the load device 21 and the sphygmomanometer 23. The load controller 22 also converts data input from the load device 21 and the sphygmomanometer 24 into data suitable for wireless LAN, and outputs the data to the AP 30.
[0041] Biometric information of the patient input into the input box 23 during or after the operation of the load device 21 is transmitted to the tablet terminal 100 and displayed on the tablet terminal 100. In addition, the measurement results of the sphygmomanometer 24 are also transmitted to the tablet terminal 100 via the load controller 22 and the AP 30 and displayed on the tablet terminal 100.
[0042] As a result, the biological information obtained by the subordinate individual units 20-1 and 20-2 is displayed on the tablet terminal 100. The medical staff can change the load of the load device 21 or stop the operation of the load device 21 by operating the tablet terminal 100 while looking at the displayed biological information.
[0043] Moreover, the biological information obtained by the plurality of unit units 101-1 to 101-n is collected and displayed on the monitoring terminal 200. This allows the user of the monitoring terminal 200 to view the biological information obtained by the plurality of unit units 101-1 to 101-n all at once. Moreover, the management database terminal 300 stores the biological information obtained by the plurality of unit units 101-1 to 101-n.
[0044] In this embodiment, a tablet terminal 100 with a small screen size is capable of displaying biometric information of a small number of people and controlling the load devices 21 of a small number of people, while a stationary monitoring terminal 200 with a large screen size is capable of displaying aggregated biometric information of a large number of people and controlling the load devices 21 of a large number of people.
[0045] In addition, in this embodiment, the tablet terminal 100 and the input box 23 are wirelessly connected, so medical staff can move around and manage cardiac rehabilitation while monitoring the condition of multiple patients without having to worry about wires. In addition, because Bluetooth communication is used for the wireless connection, the wireless connection is easy to operate, and the number of patients to be managed can also be easily changed.
[0046] <2. Pairing the tablet device 100 and the input box 23> As described above, in this embodiment, the tablet terminal 100 and the input box 23 perform wireless communication using a communication method that complies with the BLE standard.
[0047] FIG. 2 is a diagram showing the tablet terminal 100 and the input box 23 used in the cardiac rehabilitation support system 10. As described with reference to FIG. 1, in the embodiment, four tablet terminals 100-1 to 100-4 and eight input boxes 23-1 to 23-8 are used. Furthermore, a maximum of two input boxes 23 are wirelessly connected (paired) to each of the tablet terminals 100-1 to 100-4. Note that the number of input boxes 23 connected to each of the tablet terminals 100-1 to 100-4 may be one, or three or more, as described above.
[0048] Which tablet terminals 100-1 to 100-4 are paired with which input boxes 23-1 to 23-8 is selected by the tablet terminals 100-1 to 100-4.
[0049] 3 is a block diagram showing the configuration of tablet terminals 100 (100-1 to 100-4) according to the present embodiment. Note that the configuration in the figure mainly shows the parts related to Bluetooth pairing, which is a feature of the present embodiment, and other parts are simplified or omitted.
[0050] The tablet terminal 100 includes a Bluetooth communication unit 1001, an analysis unit 1002, a display / operation unit 1003, a wireless LAN communication unit 1004, a pairing processing unit 1010, and the like.
[0051] The Bluetooth communication unit 1001 performs wireless processing for performing wireless communication conforming to the Bluetooth communication standard with the input box 23. Biometric information such as ECG data sent from the input box 23 is subjected to wireless processing by the Bluetooth communication unit 1001, and then output to the analysis unit 1002, the display / operation unit 1003, and the wireless LAN communication unit 1004.
[0052] The analysis unit 1002 performs arrhythmia analysis based on, for example, ECG data, and outputs the analysis results to the display / operation unit 1003. The display / operation unit 1003 includes a so-called touch panel, and displays the ECG waveform and the analysis results. The display / operation unit 1003 also accepts touch operations by the user, and outputs an operation signal based on the touch operation to the pairing processing unit 1010. The wireless LAN communication unit 1004 transmits the biological information output from the Bluetooth communication unit 1001 and the analysis results output from the analysis unit 1002 to the load controller 22, the monitoring terminal 200, and the management database terminal 300 in a manner conforming to the wireless LAN communication standard.
[0053] The pairing processing unit 1010 includes a pairing control unit 1011, a bonding information storage unit 1012, and a pairing history storage unit 1013. The pairing processing unit 1010 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like, and each function of the pairing processing unit 1010 can be realized by the CPU reading out a program corresponding to the processing content from the ROM, expanding the program in the RAM, and executing the expanded program.
[0054] The bonding information storage unit 1012 stores bonding information such as the device address of the input box 23 required for pairing. The pairing history storage unit 1013 stores the history of paired input boxes 23. The pairing history is information such as, for example, that the previous communication was paired with the input boxes 23-1 and 23-2, and the communication before that was paired with the input boxes 23-1 and 23-5.
[0055] The pairing processing unit 1010 performs pairing processing such as switching the input box 23 to be paired based on an operation signal from the display / operation unit 1003. In addition, the pairing processing unit 1010 outputs pairing information to the display / operation unit 1003. This allows the display / operation unit 1003 to display the current pairing state, past pairing states, and the like.
[0056] Next, the pairing process according to the present embodiment will be described.
[0057] 4 is a flowchart showing the procedure of the initial pairing process. The initial pairing refers to the initial pairing process when the tablet terminal 100 is introduced into a cardiac rehabilitation facility, for example.
[0058] In step S12, the pairing control unit 1011 of the tablet terminal 100 waits for a pairing operation based on an operation signal from the display / operation unit 1003, and when the pairing operation is performed, that is, when the pairing start button is operated by the user, the process proceeds to step S13.
[0059] In step S13, the pairing control unit 1011 scans for advertising packets while switching advertising channels in a specific frequency band (for example, 2.4 GHz band), and if a positive result is obtained in the subsequent step S14, the process proceeds to step S15.
[0060] In step S15, the pairing control unit 1011 displays the name of the input box 23 that received the advertising packet on the display and operation unit 1003. In step S16, the pairing control unit 1011 makes a connection request to the input box 23 selected by the user from the input boxes 23 displayed on the display and operation unit 1003. The connection request includes various parameters such as the device address of the tablet terminal 100, the access address, the hopping and the connection interval, etc.
[0061] 5 is a diagram showing an example of an image displayed on the display / operation unit 1003 in step S15. In the diagram, "IB-00002," "IB-00003," "IB-00006," and "IB-00008" are the names of the input boxes 23 that received the advertising packet, and the user selects from these the input box 23 to be paired. Incidentally, "IB-00006," which is displayed in gray, is an input box 23 that is already connected to another tablet terminal 100, and this input box 23 cannot be selected.
[0062] In this embodiment, the tablet terminal 100 displays a plurality of input boxes 23 that have received advertising packets, and allows a plurality of input boxes 23 to be selected from the plurality of input boxes 23, and allows a user to select a plurality of input boxes 23 to be paired at once by a selection operation of the display / operation unit 1003. In this embodiment, two input boxes 23 can be selected.
[0063] In step S17, the pairing control unit 1011 connects to the input box 23 that has requested the connection.
[0064] In the next step S18, the pairing control unit 1011 stores parameters such as the device address of the input box 23 sent from the input box 23 that requested the connection as a response from the input box 23 to the connection request in the bonding information storage unit 1012 as bonding information.
[0065] In this way, the tablet terminal 100 and the input box 23 are in a paired state, and Bluetooth communication is possible.
[0066] FIG. 6 is a flowchart showing the procedure of the pairing process from the second time onward.
[0067] When the tablet terminal 100 starts the pairing process, in step S21, the pairing control unit 1011 reads out the pairing history from the pairing history storage unit 1013. In the following step S22, the pairing control unit 1011 scans an advertising packet, and if a positive result is obtained in the following step S23, the process proceeds to step S24. In step S24, the tablet terminal 100 determines whether there is an input box 23 with which the pairing control unit 1011 has been paired for a number of consecutive days equal to or greater than the threshold. For example, if the threshold is three days, it determines whether there is an input box 23 with which the pairing control unit 1011 has been paired on all of the days three days ago, two days ago, and one day ago.
[0068] If there is an input box 23 that has been paired for a number of consecutive days equal to or greater than a threshold (e.g., three days), the pairing control unit 1011 proceeds to step S25 (step S24; YES) and selects that input box 23 as the input box 23 to be paired. In the following step S26, the pairing control unit 1011 reads out bonding information of the selected input box 23 from the bonding information storage unit 1012. Then, the pairing control unit 1011 connects (pairs) with the input box 23 using the read bonding information.
[0069] On the other hand, if there is no input box 23 that has been paired for a number of consecutive days equal to or greater than the threshold (e.g., 3 days), the pairing control unit 1011 proceeds to step S28 (step S24; NO). In steps S28-S29-S30-S31, connection (pairing) with the input box 23 is performed by performing the same processes as steps S15-S16-S17-S18 of the initial pairing process described in FIG.
[0070] That is, in step S28, the pairing control unit 1011 displays the name of the input box 23 that received the advertising packet on the display and operation unit 1003. In step S29, the pairing control unit 1011 makes a connection request to the input box 23 selected by the user from the input boxes 23 displayed on the display and operation unit 1003. In step S30, the pairing control unit 1011 connects to the input box 23 that requested the connection.
[0071] In the next step S31, the pairing control unit 1011 stores parameters such as the device address of the input box 23 sent from the input box 23 that requested the connection as a response from the input box 23 to the connection request in the bonding information storage unit 1012 as bonding information.
[0072] In this way, when there is an input box 23 with which the tablet terminal 100 of the present embodiment has been paired for a number of consecutive days equal to or greater than the threshold, the tablet terminal 100 performs pairing with the input box 23 without scanning advertising packets or performing user confirmation for that input box 23. On the other hand, when there is no input box 23 with which the tablet terminal 100 has been paired for a number of consecutive days equal to or greater than the threshold, the tablet terminal 100 performs pairing by scanning advertising packets and performing user confirmation (in other words, accepting a selection operation by the user).
[0073] By doing this, for example, in a cardiac rehabilitation facility where there are a small number of tablet terminals 100 and input boxes 23, or where it is desired to have a fixed input box 23 paired with a tablet terminal 100, there will be an input box 23 that has been paired for a number of consecutive days exceeding a threshold, and pairing can be performed without unnecessary scanning of advertising packets or user confirmation.
[0074] On the other hand, in a cardiac rehabilitation facility where there are a large number of tablet terminals 100 and input boxes 23, or where there is a need to frequently change the input box 23 to be paired with the tablet terminal 100, there will be no input box 23 that has been paired for a number of consecutive days exceeding the threshold, and pairing can be performed after scanning the advertising packet and user confirmation without automatically connecting to the input box 23 with which it was previously paired.
[0075] As a result, pairing that is adapted to the usage pattern of the cardiac rehabilitation facility can be performed, thereby realizing a cardiac rehabilitation support system 10 that reduces the burden on medical staff and allows them to perform their work efficiently.
[0076] Considering that wireless devices used in daily life, such as wireless earphones, are often paired with the same smartphone, the wireless earphones are set to automatically pair with the smartphone they were previously paired with when they are turned on. However, in a cardiac rehabilitation support system in which there are multiple tablet terminals 100 and multiple input boxes 23, it may be inconvenient to fix the pairing.
[0077] Also, while there is an advantage in that the input box 23 can be freely selected once the bonding information is released, some cardiac rehabilitation facilities may wish to fix the pairing relationship between the tablet terminal 100 and the input box 23 (for example, connecting the input boxes 23-1 and 23-2 to the tablet terminal 100-1). In such facilities, releasing the bonding would be inconvenient.
[0078] The cardiac rehabilitation support system 10 of this embodiment can effectively solve these dilemmas.
[0079] As shown in FIG. 7, in which parts corresponding to those in FIG. 6 are given the same reference numerals, before connecting to an input box 23 that has been paired for a predetermined number of consecutive days or more, a query may be made to the user as to whether or not it is OK to connect to that input box 23 (step S40). Specifically, in step S40, the tablet terminal 100 displays a query image on the display / operation unit 1003 and accepts a user operation in response to the query image. If a negative result is obtained in step S40, the process proceeds to step S28, where input boxes 23 that are pairing candidates are displayed and awaits a user operation for selecting an input box 23.
[0080] <3. Summary> The above-described embodiment is merely an example of the embodiment of the present invention, and the technical scope of the present invention should not be interpreted as being limited by the embodiment. In other words, the present invention can be embodied in various forms without departing from the gist or main characteristics of the present invention.
[0081] In the above embodiment, the case where the centralized control and monitoring device 200 is provided has been described. However, for example, when a small-scale system is constructed, the centralized control and monitoring device 200 may be omitted.
[0082] In the above embodiment, the pairing control unit 1011 refers to the pairing history storage unit 1013 and controls whether or not to use the bonding information stored in the bonding information storage unit 1012 for the next pairing based on the number of days of continuous pairing, but this is not limiting. For example, the pairing control unit 1011 may refer to the pairing history storage unit 1013 and control whether or not to use the bonding information stored in the bonding information storage unit 1012 for the next pairing based on the number of consecutive pairings.
[0083] However, since it is common for cardiac rehabilitation to be performed multiple times a day in cardiac rehabilitation facilities, if pairing is fixed based on the number of consecutive sessions, the pairing may be fixed after only one day of use, which may result in unnecessary pairing. If unnecessary pairing is performed, the user must cancel the pairing and then perform a new pairing procedure, which increases the user's workload. In contrast, in the embodiment, the pairing is fixed only after a certain number of consecutive days of pairing, thereby avoiding unnecessary pairing.
[0084] In the above embodiment, the input box 23 and the tablet terminal 100 perform wireless communication conforming to the BLE communication standard, but the present disclosure is applicable to wireless communication conforming to the Bluetooth communication standard, not limited to the BLE communication standard. The present disclosure can obtain the same effect as the above embodiment when pairing is performed according to the Bluetooth communication standard. Furthermore, the present disclosure can be widely applied to wireless communication using key information exchanged by executing a key exchange protocol with each other, even when using a communication standard other than the Bluetooth communication standard.
[0085] In the above embodiment, the central terminal is the tablet terminal 100 and the peripheral terminal is the input box 23, but the present disclosure is not limited to this. The present disclosure is effective in a case where multiple central terminals and multiple peripheral terminals execute a key exchange protocol with each other, such as the Bluetooth communication standard, and perform wireless communication by pairing using exchanged key information.
[0086] The tablet terminal 100 of the present disclosure means a portable information terminal capable of wireless communication that has a display unit, an operation unit, and a signal processing unit. For example, a smartphone having a screen large enough to display biological information such as ECG of multiple patients is included in the portable information terminal capable of wireless communication of the present disclosure.
[0087] 1 is merely an example, and may be modified as appropriate. For example, in the example of FIG. 1, the load controller 22 is connected to the AP 30 via wireless LAN, but the load controller 22 may be connected to the hub 40 via a wired connection.
[0088] Furthermore, the medical stress system of the present disclosure is not limited to a cardiac rehabilitation support system, but can also be applied to, for example, a cardiac stress testing system.
[0089] As described above, the medical loading system (cardiac rehabilitation support system 10) of this embodiment has a plurality of central terminals (tablet terminal 100) and a plurality of peripheral terminals (input box 23) which execute a key exchange protocol with each other and perform wireless communication using exchanged key information, and transmits biological information of a patient to which a load is applied by a load device 21 from the peripheral terminal (input box 23) to the central terminal (tablet terminal 100) via the wireless communication, and displays the biological information on the central terminal (tablet terminal 100). The peripheral terminal (tablet terminal 100) is equipped with a pairing control unit 1011 that controls pairing with multiple peripheral terminals (input boxes 23), a bonding information storage unit 1012 that stores bonding information for pairing with the peripheral terminals (input boxes 23), and a pairing history storage unit 1013 that stores a history of paired peripheral terminals (input boxes 23), and the pairing control unit 1011 controls whether or not to use the bonding information stored in the bonding information storage unit 1012 for the next pairing based on the history stored in the pairing history storage unit 1013.
[0090] This makes it possible to realize a cardiac rehabilitation support system 10 that reduces the burden on medical professionals and enables them to perform their work more efficiently. [Industrial Applicability]
[0091] The present disclosure is widely applicable to medical load systems having a central terminal and a peripheral terminal that execute a key exchange protocol with each other and perform wireless communication using exchanged key information. [Explanation of symbols]
