Abstract

To reduce the burden on medical professionals involved in the admission and treatment of test subjects. [Solution] In the information processing system, a receiving device that communicates with at least one transmitter receives first identification information for identifying the communication channel used by the transmitter when transmitting information to the receiving device, first identification information for identifying the transmitter, and the subject's biological information associated with the transmitter. Second identification information for identifying a communication channel usable by the receiving device and second identification information for identifying a transmitter that can communicate with the receiving device are stored in advance. When the communication channel identified by the first identification information matches the communication channel identified by the second identification information, the receiving device receives biological information from the transmitter. When the transmitter identified by the first identification information matches the transmitter identified by the second identification information, the receiving device determines that biological information has been transmitted from the transmitter for a predetermined time or longer and has been received by the receiving device, and based on this information, the receiving device executes an admission process to start monitoring the subject's biological information.

[0007] Furthermore, an information processing method relating to one aspect for achieving the above objective is: An information processing method performed by a receiving device capable of communicating with at least one transmitter, The receiving device is capable of receiving from the transmitter at least first identification information for identifying the communication channel used by the transmitter when transmitting information to the receiving device using radio waves, first identification information for identifying the transmitter, and the subject's biometric information associated with the transmitter. The receiving device has in advance stored second identification information for identifying a communication channel usable by the receiving device and second identification information for identifying a transmitter that can communicate with the receiving device. When the communication channel identified by the first identified information and the communication channel identified by the second identified information coincide, the biometric information is received from the transmitter. The procedure includes the step of performing a bed admission process to start monitoring the subject's biological information based on information that determines that the biological information has been transmitted from the transmitter and received by the receiving device for a predetermined period of time or longer, when the transmitter identified by the first identification information matches the transmitter identified by the second identification information.

[0008] Furthermore, a computer program relating to one aspect for achieving the above objective is: A computer program comprising at least one instruction executed by the processor of at least one transmitter and a receiver capable of communicating with at least one transmitter, The receiving device is capable of receiving from the transmitter at least first identification information for identifying the communication channel used by the transmitter when transmitting information to the receiving device using radio waves, first identification information for identifying the transmitter, and the subject's biometric information associated with the transmitter. The receiving device has in advance stored second identification information for identifying a communication channel usable by the receiving device and second identification information for identifying a transmitter that can communicate with the receiving device. When at least one of the instructions is executed by the processor, the receiving device receives: When the communication channel identified by the first specific information and the communication channel identified by the second specific information coincide, the biometric information is received from the transmitter. When the transmitter identified by the first identification information matches the transmitter identified by the second identification information, the system determines that the biological information has been transmitted from the transmitter and received by the receiving device for a predetermined period of time or longer, and then initiates a bed entry process to start monitoring the biological information of the subject.

[0009] Furthermore, a non-temporary computer-readable medium relating to one aspect for achieving the above objective includes: The above computer program is stored.

[0010] According to the receiving device with the above configuration, when the communication channel identified by the first identification information matches the communication channel identified by the second identification information, the receiving device receives biological information from the transmitter. When the transmitter identified by the first identification information matches the transmitter identified by the second identification information, the receiving device determines that biological information has been transmitted from the transmitter and received by the receiving device for a predetermined period of time or longer, and performs admission processing to start monitoring the subject's biological information. For example, even if a medical professional does not make a predetermined input to the receiving device for admission processing, the receiving device will perform admission processing when it determines that biological information has been transmitted from the transmitter and received by the receiving device for a predetermined period of time or longer, when the transmitter identified by the first identification information matches the transmitter identified by the second identification information. In this way, the receiving device with the above configuration can reduce the burden on medical professionals involved in admission processing. Similar effects can also be achieved with the information processing method, computer program, and non-temporary computer-readable medium with the above configuration. [Effects of the Invention]

Embodiments for Carrying Out the Invention

[0013] Hereinafter, an example of an embodiment of the present disclosure will be described with reference to the drawings.

[0014] (First Embodiment) As illustrated in FIG. 1, the information processing system 100 includes a plurality of transmitters 1 and a receiving device 2. However, the information processing system 100 may include one transmitter 1. The information processing system 100 is used in a medical facility such as a hospital.

[0015] The transmitter 1 is, for example, a portable medical telemeter or the like used by medical staff in a medical facility such as a hospital. In the present embodiment, each of the transmitters 1 is assigned to a specific single subject. Therefore, in a medical facility such as a hospital, for example, a subject can be identified by identifying the transmitter 1. The transmitter 1 can measure and / or display the biological information of the subject. The biological information used in the present embodiment is preferably biological information that is continuously measured over time, such as electrocardiogram waveform data, percutaneous arterial oxygen saturation (SpO2), heart rate, respiratory rate, and the like. The transmitter 1 can communicate wirelessly with the receiving device 2 when second specific information described later is registered in the receiving device 2. Thereby, the transmitter 1 can transmit various information to the receiving device 2. The various information includes, for example, biological information measured by the transmitter 1, first specific information for identifying a communication path used when the transmitter 1 transmits information to the receiving device 2 using radio waves, first identification information for identifying the transmitter 1, and the like.

[0016] The first identifying information is, for example, information indicating the communication path, such as the channel and frequency, used when transmitter 1 transmits information to receiver 2 using radio waves. A channel is a path for transmitting various types of information, such as biological information, and is represented by a number, such as "1001". Therefore, the first identifying information is, for example, the transmission channel number. In medical facilities such as hospitals, each transmitter 1 is assigned a different channel, and it is assumed that the correspondence between channels and transmitters will not be changed. Therefore, in medical facilities such as hospitals, transmitter 1 can be identified by identifying the channel, for example. For this reason, in medical facilities such as hospitals, a subject can be identified by identifying the channel, for example. Also, for example, if a certain transmitter 1 is to be used in a certain ward, it is necessary to register in advance the information indicating the channel that transmitter 1 uses when transmitting information (specifically, the second identifying information described later) in the receiver 2 located in that ward. For this reason, a large number of channels (channels assigned to transmitter 1) are registered in the receiver 2. The channel registration status in the receiver 2 is changed as appropriate for each ward, according to the admission and discharge of subjects. The primary identification information is, for example, the hospital ID pre-set for transmitter 1. The hospital ID is an identifier indicating a medical facility or department, and is used to prevent misdisplay of biometric information transmitted from other hospitals via the same communication channel. The hospital ID is represented by a number, such as "1".

[0017] In this embodiment, biological information is classified into genuine biological information that is transmitted and received normally, and non-genuine biological information that is not transmitted and received normally. Here, "genuine biological information that is transmitted and received normally" refers to biological information that is transmitted from transmitter 1 to receiver 2 via a pre-set communication channel and received by receiver 2. Conversely, "non-genuine biological information that is not transmitted and received normally" refers to biological information that corresponds to noise affected by so-called body movements, or biological information that is transmitted at a frequency used in communication between transmitter 1 and receiver 2, but which should not have been transmitted to receiver 2 in the first place. Therefore, in this embodiment, for example, even if biological information shows a value outside the appropriate range, if it is transmitted from transmitter 1 to receiver 2 via a pre-set communication channel and received by receiver 2, it is considered genuine biological information. In other words, for example, biological information representing arrhythmia can be genuine biological information.

[0018] When transmitter 1 transmits biological information to receiver 2 for a predetermined period of time or longer, it generates information indicating that transmitter 1 has transmitted biological information to receiver 2 for a predetermined period of time or longer, such as flag information. Note that the information indicating that transmitter 1 has transmitted biological information to receiver 2 for a predetermined period of time or longer is not limited to flag information. Transmitter 1 transmits the generated flag information to receiver 2.

[0019] The receiving device 2 is, for example, a central monitor. The receiving device 2 is capable of communicating with the transmitter 1. The receiving device 2 includes an input / output interface 21, a storage device 22, and a control unit 23. These are connected to each other via a bus 24 so that they can communicate with one another.

[0020] The input / output interface 21 functions as an interface between the transmitter 1 and the receiver 2.

[0021] The storage device 22 is configured to store various types of data, for example. The storage device 22 is, for example, a storage device such as an HDD (Hard Disk Drive), SSD (Solid State Drive), or flash memory. The storage device 22 pre-stores, for example, second identification information for identifying a communication channel usable by the receiving device 2 and second identification information for identifying a transmitter 1 that can communicate with the receiving device 2. The second identification information is, for example, information indicating the channels and frequencies that the receiving device 2 can use when receiving information from the transmitter 1 using radio waves. The second identification information is, for example, a hospital ID pre-set for the receiving device 2. The receiving device 2 can receive various types of information from the transmitter 1 when the communication channel identified by the first identification information matches the communication channel identified by the second identification information.

[0022] The control unit 23 includes a memory 231 and a processor 232 as its hardware configuration. The memory 231 consists of, for example, a ROM (Read Only Memory) in which various computer programs are stored, and a RAM (Random Access Memory) having multiple work areas in which various computer programs executed by the processor 232 are stored. The processor 232 is, for example, a CPU (Central Processing Unit) which is configured to load a specified computer program from the various computer programs embedded in the ROM onto the RAM and execute various processes in cooperation with the RAM.

[0023] In this embodiment, computer-readable media may be used. Computer-readable media refers to any type of physical memory (RAM, ROM, etc.) that can store information and data that a processor can read. Computer-readable media can store instructions related to processing performed by one or more processors. The term "computer-readable media" includes tangible items but excludes carrier waves and temporary signals (i.e., it refers to non-temporary items). Examples of non-temporary computer-readable media include magnetic recording media (e.g., flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (e.g., magneto-optical disks), CD-ROMs (Read Only Memory), CD-Rs, CD-R / Ws, and semiconductor memory (e.g., mask ROMs, PROMs (Programmable ROMs), EPROMs (Erasable PROMs), flash ROMs).

[0024] The control unit 23 determines whether it has received the first identification information from transmitter 1 when the communication channel identified by the first identification information and the communication channel identified by the second identification information coincide. The control unit 23 also determines whether the transmitter 1 identified by the first identification information and the transmitter 1 identified by the second identification information coincide when the communication channel identified by the first identification information and the communication channel identified by the second identification information coincide. If the control unit 23 determines that it has not received the first identification information from transmitter 1, or that the transmitter 1 identified by the first identification information and the transmitter 1 identified by the second identification information do not coincide, it determines that interference is occurring. Based on this determination, the control unit 23 generates interference information indicating that interference is occurring. The control unit 23 transmits the interference information to the storage device 22.

[0025] The control unit 23 determines whether biological information has been transmitted from transmitter 1 and received by receiver 2 for a predetermined time or longer when the transmitter 1 identified by the first identification information matches the transmitter 1 identified by the second identification information. If the control unit 23 determines that biological information has been transmitted from transmitter 1 and received by receiver 2 for a predetermined time or longer, it generates transmission and reception confirmation information indicating that biological information has been transmitted from transmitter 1 and received by receiver 2 for a predetermined time or longer. Based on the transmission and reception confirmation information, the control unit 23 executes admission processing to start monitoring the subject's biological information. Thus, the transmission and reception confirmation information can be information that triggers the control unit 23 to start admission processing. In other words, in this embodiment, the control unit 23 executes admission processing as a trigger when it generates the transmission and reception confirmation information. Therefore, in this embodiment, it can be said that the control unit 23 executes admission processing when it determines that biological information has been transmitted from transmitter 1 and received by receiver 2 for a predetermined time or longer. The admission process refers to initiating monitoring of the subject's vital signs. Once admission is performed, information such as the subject's bio-waveforms and measurements from medical devices (an example of the subject's vital signs) will be displayed on the central monitor (an example of receiving device 2). Furthermore, once admission is performed, the central monitor will be in a state where medical personnel can input information such as the subject's height and weight on the admission screen displayed on the central monitor.

[0026] The control unit 23 may be configured to transition the state of the receiving device 2 from the first state to the second state if the transmitter 1 identified by the first identification information matches the transmitter 1 identified by the second identification information. The first state is a state in which it is impossible to receive flag information from the transmitter 1, and the second state is a state in which it is possible to receive flag information from the transmitter 1. In this case, when the state of the receiving device 2 is the second state, the control unit 23 may determine whether the receiving device 2 has received flag information from the transmitter 1. In this case, the control unit 23 executes the bed admission process to start monitoring the subject's biological information based on the flag information received from the transmitter 1. In other words, in this case, when the state of the receiving device 2 is the second state, the control unit 23 determines that the receiving device 2 has received flag information from the transmitter 1 and executes the bed admission process.

[0027] (First embodiment of the first embodiment) Next, with reference to Figure 2, the information processing method implemented in the first embodiment of the first embodiment will be described. Figure 2 is a flowchart illustrating the information processing method implemented in the first embodiment of the first embodiment.

[0028] In this embodiment, the control unit 23 determines whether the receiving device 2 has received genuine biological information from transmitter 1 for a predetermined time or longer when the transmitter 1 identified by the first identification information matches the transmitter 1 identified by the second identification information. In this embodiment, the first and second identification information are hospital IDs, the hospital ID corresponding to the first identification information is referred to as the first hospital ID, and the hospital ID corresponding to the second identification information is referred to as the second hospital ID. In this embodiment, the predetermined time is 10 seconds. However, the predetermined time is not limited to this example. When the control unit 23 determines that the receiving device 2 has received genuine biological information from transmitter 1 for a predetermined time or longer, it generates transmission and reception confirmation information. Therefore, the transmission and reception confirmation information generated by the control unit 23 in this embodiment is information indicating that genuine biological information has been transmitted from transmitter 1 and received by the receiving device 2 for a predetermined time or longer.

[0029] As illustrated in Figure 2, transmitter 1 transmits various information to receiver 2 (STEP 01). The various information that transmitter 1 transmits to receiver 2 in STEP 01 includes, for example, biological information, first identification information and first hospital ID, or biological information and first identification information. The biological information that transmitter 1 transmits to receiver 2 in STEP 01 includes genuine biological information.

[0030] If the channel specified by the first identification information (an example of a communication channel) matches the channel specified by the second identification information (YES in STEP 02), the receiving device 2 receives the various information transmitted from the transmitter 1 (STEP 03). On the other hand, if the channel specified by the first identification information does not match the channel specified by the second identification information (NO in STEP 02), the receiving device 2 does not receive the various information transmitted from the transmitter 1 (STEP 04). In this case, no further information processing is performed.

[0031] After STEP 03, the control unit 23 of the receiving device 2 determines whether the receiving device 2 has received the First Hospital ID from the transmitter 1 (STEP 05). In other words, the control unit 23 determines whether the First Hospital ID is included in the various information received from the transmitter 1. If the receiving device 2 has received the First Hospital ID from the transmitter 1 (YES in STEP 05), the control unit 23 executes STEP 06. On the other hand, if the receiving device 2 has not received the First Hospital ID from the transmitter 1 (NO in STEP 05), the control unit 23 determines that interference is occurring and generates interference information based on that determination (STEP 07).

[0032] In STEP 06, the control unit 23 determines whether the transmitter 1 identified by the first hospital ID matches the transmitter 1 identified by the second hospital ID. If the transmitter 1 identified by the first hospital ID matches the transmitter 1 identified by the second hospital ID (YES in STEP 06), the control unit 23 executes STEP 08. On the other hand, if the transmitter 1 identified by the first hospital ID does not match the transmitter 1 identified by the second hospital ID (NO in STEP 06), the control unit 23 generates interference information (STEP 07).

[0033] In STEP 08, the control unit 23 determines whether the receiving device 2 has received genuine biological information from the transmitter 1 for a predetermined time (10 seconds in this embodiment) or longer. If the control unit 23 determines that the receiving device 2 has received genuine biological information from the transmitter 1 for a predetermined time or longer (YES in STEP 08), it generates transmission and reception confirmation information (STEP 09). Then, after generating the transmission and reception confirmation information, the control unit 23 executes the bed admission process based on the generated transmission and reception confirmation information (STEP 10). In other words, the control unit 23 executes the bed admission process triggered by the generation of the transmission and reception confirmation information. On the other hand, if the control unit 23 determines that the receiving device 2 has not received genuine biological information from the transmitter 1 for a predetermined time or longer (NO in STEP 08), it executes STEP 08 again.

[0034] According to the receiving device 2 in the above configuration, for example, even if a medical professional does not perform a predetermined input to the receiving device 2 for bed admission processing, the receiving device 2 will execute bed admission processing when it determines that biological information has been transmitted from transmitter 1 for a predetermined time or longer and received by the receiving device 2, based on the matching of transmitter 1 identified by the first hospital ID (first identification information) and transmitter 1 identified by the second hospital ID (second identification information). In this way, the receiving device 2 can reduce the burden on medical professionals involved in bed admission processing. Furthermore, similar effects can be achieved with the information processing method, computer program, and non-temporary computer-readable medium in the above configuration.

[0035] Furthermore, with the receiving device 2 according to the above configuration, the bed admission process is executed when it is determined that genuine biological information has been transmitted from the transmitter 1 for a predetermined period of time or longer and has been received by the receiving device 2, thus enabling more accurate bed admission processing.

[0036] Furthermore, according to the receiving device 2 with the above configuration, if it determines that it has received biological information from the transmitter 1 for a predetermined period of time or longer, it will perform the bed admission process. Therefore, even if the configuration of the transmitter 1 is simple, for example, the receiving device 2 can automatically perform the bed admission process.

[0037] (Second embodiment of the first embodiment) Next, with reference to Figure 3, the information processing method implemented in the second embodiment of the first embodiment will be described. Figure 3 is a flowchart illustrating the information processing method implemented in the second embodiment of the first embodiment.

[0038] In this embodiment, when transmitter 1 transmits genuine biological information to receiver 2 for a predetermined time (10 seconds in this embodiment) or longer, it generates flag information as information indicating that transmitter 1 has transmitted genuine biological information to receiver 2 for a predetermined time (10 seconds in this embodiment) or longer. Also in this embodiment, if transmitter 1 identified by the first hospital ID (first identification information) matches transmitter 1 identified by the second hospital ID (second identification information), control unit 23 transitions the state of receiver 2 from the first state to the second state. Furthermore, in this embodiment, when the state of receiver 2 is the second state, control unit 23 determines whether receiver 2 has received flag information from transmitter 1. If control unit 23 determines that receiver 2 has received flag information from transmitter 1, it executes admission processing based on the flag information received from transmitter 1. In other words, this embodiment differs from the first embodiment of the first embodiment in that the control unit 23 of receiver 2 executes admission processing based on flag information rather than transmission / reception confirmation information.

[0039] As illustrated in Figure 3, steps 21 to 27 are the same as steps 01 to 07 in the first embodiment of the first embodiment. In this embodiment, when the transmitter 1 identified by the first hospital ID matches the transmitter 1 identified by the second hospital ID (YES in step 26), the state of the receiving device 2 transitions from the first state to the second state (step 28).

[0040] The control unit 23 of the receiving device 2 determines whether the receiving device 2 has received flag information from the transmitter 1 (STEP 29). If the control unit 23 determines that the receiving device 2 has received flag information from the transmitter 1 (YES in STEP 29), it executes the bed entry process (STEP 30). On the other hand, if the control unit 23 determines that the receiving device 2 has not received flag information from the transmitter 1 (NO in STEP 29), it executes STEP 29 again.

[0041] In this embodiment as well, the receiving device 2 provides the same effects as in the first embodiment of the first embodiment.

[0042] Furthermore, according to the above configuration of the receiving device 2, when the receiving device 2 receives information (flag information) from the transmitter 1 indicating that the transmitter 1 has transmitted biological information to the receiving device 2 for a predetermined time (10 seconds in this embodiment) or longer, it executes the bed admission process. In other words, the receiving device 2 does not need to generate transmission and reception confirmation information when performing the bed admission process, and can execute the bed admission process simply by determining whether or not it has received flag information from the transmitter 1. For this reason, the receiving device 2 according to the above configuration can reduce the burden of information processing performed by the receiving device 2.

[0043] (Third embodiment of the first embodiment) Next, with reference to Figure 4, the information processing method implemented in the third embodiment of the first embodiment will be described. Figure 4 is a flowchart illustrating the information processing method implemented in the third embodiment of the first embodiment.

[0044] In this embodiment, the receiving device 2 receives multiple different types of biological information (in this embodiment, electrocardiogram waveform data and transcutaneous arterial oxygen saturation) from the transmitter 1. In this embodiment, the control unit 23 of the receiving device 2 generates transmission and reception confirmation information when all types of biological information received from the transmitter 1 are genuine biological information and genuine biological information has been received from the transmitter 1 for a predetermined period of time or longer, and executes admission processing based on said transmission and reception confirmation information. In other words, this embodiment differs from the first embodiment of the first embodiment in that the control unit 23 executes admission processing when all types of biological information are genuine biological information. For this reason, in this embodiment, the control unit 23 determines whether all types of biological information received from the transmitter 1 are genuine biological information.

[0045] As illustrated in Figure 4, the transmitter 1 transmits various types of information, including multiple different types of biological information, to the receiver 2 (STEP 41). In this embodiment, the transmitter 1 transmits two different types of biological information (electrocardiogram waveform data and transcutaneous arterial oxygen saturation) to the receiver 2.

[0046] Steps 42 to 47 are the same as steps 01 to 07 in the first embodiment of the first model. In this model, in step 43, the receiving device 2 receives various types of information, including multiple different types of biological information.

[0047] In STEP 48, the control unit 23 of the receiving device 2 determines whether all types of biological information received from the transmitter 1 are genuine biological information. If the control unit 23 determines that all types of biological information received from the transmitter 1 are genuine biological information (YES in STEP 48), it executes STEP 49. On the other hand, if the control unit 23 determines that at least one type of biological information received from the transmitter 1 is not genuine biological information (NO in STEP 48), it terminates this information processing.

[0048] Steps 49 to 51 are the same as steps 8 to 10 in the first embodiment of the first model.

[0049] In this embodiment as well, the receiving device 2 provides the same effects as in the first embodiment of the first embodiment.

[0050] Furthermore, with the receiving device 2 according to the above configuration, the bed admission process is executed only when all types of biological information received from the transmitter 1 are genuine biological information, thus enabling more accurate bed admission processing.

[0051] (Second embodiment) Next, the information processing system 100A according to the second embodiment will be described with reference to Figures 5 and 6. In this embodiment, parts similar to those in the first embodiment will be described using the same reference numerals as in the first embodiment, and descriptions of overlapping parts will be omitted as appropriate. Figure 5 is a system configuration diagram of the information processing system 100A according to the second embodiment. Figure 6 is a flowchart illustrating an information processing method executed in the second embodiment. As illustrated in Figure 5, the information processing system 100A includes a transmitter 1, a receiving device 2, and a monitoring device 3. In other words, the information processing system 100A according to this embodiment differs from the information processing system 100 according to the first embodiment in that it includes a monitoring device 3. In this embodiment, the input / output interface 21 of the receiving device 2 functions not only as an interface between the transmitter 1 and the receiving device 2, but also as an interface between the receiving device 2 and the monitoring device 3.

[0052] As illustrated in Figure 5, the monitoring device 3 is communicatively connected to the receiving device 2. In this embodiment, the receiving device 2 transmits, for example, the biological information received from the transmitter 1 to the monitoring device 3. Therefore, in this embodiment, the monitoring device 3 receives biological information from the receiving device 2. In this embodiment, the biological information transmitted by the receiving device 2 to the monitoring device 3 may include genuine biological information. The monitoring device 3 includes an input / output interface 31 and a control unit 32. These are communicatively connected to each other via a bus 33.

[0053] The input / output interface 31 functions as an interface between the receiving device 2 and the monitoring device 3.

[0054] The control unit 32 includes a memory 321 and a processor 322 as its hardware configuration. The memory 321 consists of, for example, a ROM (Read Only Memory) in which various computer programs are stored, and a RAM (Random Access Memory) having multiple work areas in which various computer programs executed by the processor 322 are stored. The processor 322 is, for example, a CPU (Central Processing Unit) which is configured to load a specified computer program from the various computer programs embedded in the ROM onto the RAM and execute various processes in cooperation with the RAM.

[0055] The control unit 32 determines whether the receiving device 2 has received genuine biological information from the transmitter 1 for a predetermined time (for example, 10 seconds) or longer. For example, the control unit 32 determines that the receiving device 2 has received genuine biological information from the transmitter 1 for a predetermined time or longer when the monitoring device 3 receives genuine biological information from the receiving device 2 for a predetermined time or longer.

[0056] When the control unit 32 determines that the receiving device 2 has received genuine biological information from the transmitter 1 for a predetermined period of time or longer, it generates transmission and reception confirmation information. The control unit 32 transmits the generated transmission and reception confirmation information to the receiving device 2. Therefore, in this embodiment, the receiving device 2 receives the transmission and reception confirmation information from the monitoring device 3. Furthermore, in this embodiment, the receiving device 2 executes the bed admission process based on the transmission and reception confirmation information received from the monitoring device 3. In other words, in this embodiment, when the control unit 23 determines that it has received the transmission and reception confirmation information from the monitoring device 3, it executes the bed admission process.

[0057] In this embodiment, the information processing method illustrated in Figure 6 is executed. Steps 61 to 67 are the same as steps 01 to 07 in the first embodiment of the first embodiment.

[0058] The receiving device 2 transmits the biological information received from the transmitter 1 to the monitoring device 3 (STEP 68).

[0059] The control unit 32 of the monitoring device 3 determines whether the receiving device 2 has received genuine biological information from the transmitter 1 for a predetermined period of time or longer (STEP 69). If the control unit 32 determines that the receiving device 2 has received genuine biological information from the transmitter 1 for a predetermined period of time or longer (YES in STEP 69), it generates transmission and reception confirmation information (STEP 70). On the other hand, if the control unit 32 determines that the receiving device 2 has not received genuine biological information from the transmitter 1 for a predetermined period of time or longer (NO in STEP 69), it executes STEP 69 again.

[0060] The monitoring device 3 transmits the generated transmission and reception confirmation information to the receiving device 2 (STEP 71).

[0061] STEP 72 is the same as STEP 10 in the first embodiment of the first embodiment. In this embodiment, the control unit 23 performs bed entry processing based on the transmission and reception confirmation information received from the monitoring device 3.

[0062] In this embodiment as well, the receiving device 2 provides the same effects as in the first embodiment.

[0063] Furthermore, according to the receiving device 2 in the above configuration, the bed entry process is executed upon receiving transmission / reception confirmation information from the monitoring device 3. In other words, according to the receiving device 2 in the above configuration, the receiving device 2 does not need to generate transmission / reception confirmation information when performing the bed entry process, and executes the bed entry process upon receiving transmission / reception confirmation information from the monitoring device 3, thus reducing the information processing burden on the receiving device 2.

[0064] The embodiments described above are provided to facilitate understanding of this disclosure and do not limit it. This disclosure may be modified or improved without departing from its intent.

[0065] In the first embodiment of the first embodiment, the control unit 23 of the receiving device 2 generates transmission and reception confirmation information when it determines that the receiving device 2 has received genuine biological information from the transmitter 1 for a predetermined time or longer. However, the disclosure is not limited to this example. For example, the control unit 23 may generate transmission and reception confirmation information when it determines that the receiving device 2 has received biological information from the transmitter 1 for a predetermined time or longer. In other words, in this case, the control unit 23 generates transmission and reception confirmation information even if it determines that the receiving device 2 has received non-genuine biological information from the transmitter 1 for a predetermined time or longer. Similarly, in the second embodiment, the control unit 32 of the monitoring device 3 may generate transmission and reception confirmation information when it determines that the receiving device 2 has received biological information from the transmitter 1 for a predetermined time or longer.

[0066] In the second embodiment of the first embodiment, the transmitter 1 generates flag information when it transmits genuine biological information to the receiving device 2 for a predetermined period of time or longer, but the disclosure is not limited to this example. For example, the transmitter 1 may generate flag information when it transmits biological information to the receiving device 2 for a predetermined period of time or longer. In other words, in this case, the transmitter 1 generates flag information even if it transmits non-genuine biological information to the receiving device 2 for a predetermined period of time or longer.

[0067] In the third embodiment of the first embodiment, two different types of biological information (electrocardiogram waveform data and transcutaneous arterial oxygen saturation) are used, but three or more different types of biological information may be used.
