Description

  The present invention relates to a biological information measuring device, and more particularly to a technique for performing wireless communication when a plurality of biological information measuring devices exist.

A data transmission method by wireless communication of a plurality of conventional wireless terminal-to-terminal communication devices will be described.
FIG. 8 shows a state of wireless communication of a conventional wireless communication terminal. In FIG. 8, when the wireless communication terminal 100a wants to transmit data 110 to the wireless communication terminal 100b, the wireless communication terminal 100a transmits a transmission prohibit command for prohibiting transmission to the wireless communication terminal 100b and the wireless communication terminal 100c. . Then, the wireless communication terminal 100b and the wireless communication terminal 100c that have received the transmission prohibition command are switched from a state in which transmission / reception is possible to a state in which only reception is possible.

The wireless communication terminal 100a transmits data to the wireless communication terminal 100b, and transmits a transmission prohibition release command (not shown) for canceling the transmission prohibition to the wireless communication terminal 100b and the wireless communication terminal 100c after the transmission is completed. . Then, the wireless communication terminal 100b and the wireless communication terminal 100c that have received the transmission prohibition release command are switched from a state in which only reception is possible to a state in which transmission / reception is possible. Therefore, when one wireless communication terminal starts transmission, the transmission of other wireless communication terminals is prohibited, thereby realizing communication of a plurality of wireless communication terminals avoiding radio wave interference (for example, Patent Documents). 1).
JP-A-5-3477

  However, in the conventional configuration, when one wireless communication terminal (for example, 100a) among the plurality of wireless communication terminals starts data transmission, the other wireless communication terminals (for example, 100b and 100c) Cannot send. Therefore, even when another wireless communication terminal must immediately transmit while one wireless communication terminal 100a is performing data transmission, the other wireless communication terminal is a wireless communication terminal that is performing wireless communication. Therefore, there is a problem that data transmission can be made to wait until a communication prohibition release command is received.

  The present invention solves the above-described conventional problems, and provides a biological information measuring device capable of promptly performing wireless communication of data that requires urgent transmission in wireless communication of a plurality of wireless communication devices.

If it is a value, the communication interruption command is repeatedly transmitted for a time longer than the wireless transmission time when transmitting the measurement value to the medical device.

  Further, in the biological information measuring apparatus, the transmission unit repeatedly transmits the communication interruption command, then issues a command to the reception unit to measure radio waves existing in a surrounding environment, and the reception unit performs wireless communication. When it is determined that there is a living body information measuring device, the transmission unit transmits the communication interruption command and receives radio waves existing in the surrounding environment until the device performing wireless communication interrupts or terminates wireless communication. It is characterized by repeating.

When it is determined that there is no living body information measuring apparatus, the transmitting unit transmits the measured value of the living body information to the medical device.

  Furthermore, in the biological information measuring device, when the transmitting unit determines that there is another biological information measuring device performing wireless communication, if the measured value of the biological information is a normal value, the wireless communication ends. After waiting, the measurement value of the biological information is transmitted to the medical device.

  Further, in the biological information measuring device, when the transmission is interrupted by the communication interruption command, when the wireless communication completion notification for the biological information measuring device currently communicating from the medical device is received, the transmission unit is interrupted. The wireless communication is resumed.

The biometric information calculation unit will be described as a blood glucose level calculation unit with a portable management terminal owned by a doctor or nurse who manages the blood glucose information.

  FIG. 1 shows a block diagram of a biological information measuring apparatus and peripheral devices according to the first embodiment of the present invention. In FIG. 1, the biological information measuring apparatus 2 according to the present invention includes a blood sugar level calculating unit 21 that calculates a blood sugar level from the biosensor 1, a transmitting unit 22 that transmits data to the mobile management terminal 3, and a mobile management terminal 3. It comprises a receiving unit 23 that receives data, a storage unit 24 that stores information necessary for calculating blood glucose levels, and a display unit 25 that displays the calculated blood glucose levels. Further, the transmission unit 22 includes a transmission circuit 221 that transmits data, and a communication control circuit 222 that controls the transmission circuit 221 and the reception unit 23.

  The biological information measuring device 2 is used by a user suffering from diabetes to measure his / her blood glucose level. However, since the biological information measuring device 2 needs to be measured several times a day, it is small and lightweight so that it can be measured even when going out. Goods are widely used. An electrochemical and disposable biosensor 1 is connected to the biological information measuring device 2, and blood is spotted on the biosensor 1. The biological information measuring device 2 measures the blood sugar level from the biosensor 1 connected using the blood sugar level calculating unit 21.

  The blood glucose level calculation unit 21 calculates the blood glucose level of the biosensor 1 and outputs the calculated blood glucose level data to the transmission unit 22, the storage unit 24, and the storage unit 24.

  The communication control circuit 222 issues an RSSI acquisition command for acquiring the received power of the carrier wave (hereinafter referred to as RSSI (Received Signal Strength Indicator)) to the receiving unit 23 or receives data transmitted from the mobile management terminal 3 To issue a reception start command. Further, the communication control circuit 222 issues a blood sugar level transmission command for transmitting the blood sugar level to the transmission circuit 221 and issues a transmission stop command for interrupting wireless communication of the biological information measuring device 2 in the vicinity. Or

  The transmission circuit 221 is controlled by the communication control circuit 222 and transmits data to the mobile management terminal 3 and the like. Also, after generating transmission data in a format consisting of blood glucose level, error detection data, and communication continuation information, the transmission data is modulated and transmitted to the mobile management terminal 3 with a preamble pattern and a sync pattern added to the head. To do.

  The receiving unit 23 acquires the RSSI of the carrier wave when receiving the RSSI acquisition command, or receives data transmitted from the mobile management terminal 3 when receiving the reception start command. Details of the receiving unit 23 will be described later.

  The storage unit 24 stores parameter information for calculating a blood glucose level based on the detection value of the biosensor 1 and data of the calculated blood glucose level.

  The display unit 25 displays the blood sugar level data output from the blood sugar level calculating unit 21.

Hereinafter, detailed description of the internal blocks of the biological information measuring apparatus 2 will be given.
FIG. 2 shows a block diagram of the blood sugar level calculating unit 21, and the blood sugar level calculating unit 21 will be described in detail. When a disposable electrochemical biosensor 1 is inserted into the connector 211 and blood is spotted on the reactant 13 composed of an enzyme, a mediator or the like disposed between the working electrode 11 and the counter electrode 12 of the biosensor 1, the reactant 13 is dissolved in the blood and the enzymatic reaction proceeds. Next, when a voltage is applied from the operational amplifier 212 to the working electrode 11 and the counter electrode 12 through the electrode 2111 in contact with the working electrode 11 of the biosensor 1 and the electrode 2112 in contact with the counter electrode 12 of the biosensor 1, the sugar concentration in the blood is obtained. A correlated current flows to the biosensor 1 through the feedback resistor 213.

  Here, the non-inverting input terminal 2122 of the operational amplifier 212 is connected to the reference potential 214, and the operational amplifier 212 controls to keep the non-inverting input terminal 2122 and the inverting input terminal 2121 at the same potential. A voltage obtained by adding the potential of the drop due to the current to the reference potential 214 is generated at the output terminal 2123. By this action, a voltage proportional to the current flowing through the biosensor 1 is generated at the output terminal 2123, and current-voltage conversion can be performed. The voltage generated at the output terminal 2123 is converted into a digital value by the A / D conversion circuit 215, the sugar concentration in the blood is calculated from the current value sent to the arithmetic circuit 216 and flowing to the biosensor 1, and the transmission unit 22 And transferred to the storage unit 24 and the display unit 25.

  In calculating the blood sugar concentration, for example, the following processing is performed. That is, at the factory, two constant current sources that generate currents corresponding to the low sugar concentration and the high sugar concentration are connected in advance between the electrode 2111 and the electrode 2112 of the connector 211, and the current is calculated from each A / D conversion value. A primary conversion equation of the value and the digital value is obtained by the arithmetic circuit 216. The slope a and intercept b of the primary conversion equation are information that associates the digital value output from the A / D conversion circuit with the sugar concentration, and this is stored in the storage unit 24. When a diabetic patient measures a blood glucose level, the arithmetic circuit 216 applies the digital value obtained from the A / D conversion circuit 215 to the primary conversion equation stored in the storage unit 24 to thereby determine the blood sugar concentration (hereinafter referred to as blood glucose level). (Referred to as value). The calculated blood glucose level is transferred to the transmission unit 22, the storage unit 24, and the display unit 25.

  FIG. 3 is a block diagram of the receiving unit 23, and FIG. 4 is a control flowchart of the receiving unit 23. The receiving unit 23 will be described in detail.

  When receiving the reception start command from the communication control circuit 222 (described in FIG. 1) inside the transmission unit 22, the reception control circuit 231 issues a reception start command to the reception circuit 232 so as to receive radio waves. The reception circuit 232 performs processing such as carrier wave detection, gain control, and conversion to an intermediate frequency from the received signal, and transfers the processed data to the preamble detection circuit 233, the sync pattern detection circuit 234, and the demodulation circuit 235. To do. At the same time, the reception level of the carrier wave received is transferred to the reception control circuit 231. The reception control circuit 231 calculates RSSI from the reception level of the transferred carrier wave (S101). The reception control circuit 231 calculates RSSI even when receiving an RSSI acquisition command from the communication control circuit 222, and outputs the calculated RSSI to the communication control circuit 222.

  The preamble detection circuit 233 detects the preamble pattern, and outputs a start pulse to the sync pattern detection circuit 234 when the preamble pattern can be detected (S102). The sync pattern detection circuit 234 detects the sync pattern from the reception data output from the reception circuit 232 in response to the start pulse from the preamble detection circuit 233 (S103).

  The demodulation circuit 235 demodulates the received data based on the sync pattern detected by the sync pattern detection circuit 234, and the demodulated received data is stored in the reception register 236. When error detection data in the received data is stored in the reception register 236, the reception register 236 outputs a start pulse to the error detection circuit 237 (S104). When receiving the activation pulse, the error detection circuit 237 checks whether there is an error in the data transmitted from the biological information measuring device 2 stored in the reception register 236 and outputs the result to the reception control circuit 231. .

  The reception control circuit 231 receives the result notification from the error detection circuit 237 and determines whether or not there is an error in the received data (S105). If an error is detected in the received data in S105, a message to that effect is output to the communication control circuit 222 and the receiving operation is terminated. If no error is detected in the received data in S105, a specific area of the transmitted data is confirmed. If a code indicating a wireless communication completion notification is present in the specific area, the wireless communication completion notification is output to the communication control circuit 222, and the reception operation is terminated. Is present, the communication interruption command is received, and RSSI and the communication interruption command are received are output to the communication control circuit 222 (S106), and the receiving operation is terminated.

  FIG. 5 shows a control flowchart of the transmission unit 22, and the transmission unit 22 will be described in detail with reference to FIGS. 1 and 5.

  When blood sugar level data is transferred from the blood sugar level calculating unit 21, the communication control circuit 222 issues an RSSI acquisition command to the receiving unit 23. The receiving unit 23 that has received the RSSI acquisition command outputs the RSSI to the communication control circuit 222. The communication control circuit 222 determines whether the RSSI obtained from the receiving unit 23 is larger than the reference value. If the RSSI obtained from the receiving unit 23 is larger than the reference value, it is determined that the other biological information measuring device 2 in the vicinity is performing wireless communication. It is determined that the measuring device 2 is not performing wireless communication (S501). Here, the reference value is set to a level (for example, −80 dBm or less) at which it can be determined that other biological information measuring devices 2 in the vicinity are not performing wireless communication.

  If it is determined in S501 that wireless communication is not being performed, a data transmission / reception step is executed for the mobile management terminal 3 (S502). The data transmission / reception step will be described later.

  If it is determined in S501 that wireless communication is being performed, the communication control circuit 222 determines whether or not the measured blood glucose level is greater than the reference value (S503). The reference value here is a value (eg, 400 mg / dl or more) that may cause coma or death due to an abnormal blood glucose level.

  If the blood glucose level measured in S503 is greater than the reference value, the communication control circuit 222 issues a transmission stop command to the transmission circuit 221 as urgent. The transmission circuit 221 that has received the transmission stop command repeatedly transmits a communication interruption command to other biological information measuring devices 2 in the vicinity for a predetermined transmission time (for example, 2 seconds) (S504). Then, after the transmission circuit 221 finishes repeatedly transmitting the communication interruption command for 2 seconds, the communication control circuit 222 receives the same as in S501 in order to confirm that another biological information measuring apparatus 2 in the vicinity has been urgently interrupted. The RSSI acquisition command is issued to the unit 23, and it is determined whether or not the RSSI obtained from the receiving unit 23 is larger than the reference value (S505).

  If it is determined in S505 that wireless communication is being performed, the communication is interrupted for a predetermined transmission time (for example, 2 seconds) in order to urgently interrupt the wireless communication of another biological information measuring device 2 in the vicinity again. The command is repeatedly transmitted (S504). If it is determined in S505 that wireless communication is not being performed, a data transmission / reception step is executed for the mobile management terminal 3 (S502).

  If the blood glucose level measured in S503 is equal to or lower than the reference value, the process waits until the wireless communication of the other biological information measuring device 2 in the vicinity ends (S506), and then executes a data transmission / reception step (S502).

  Next, the data transmission / reception step (S502) will be described. FIG. 6 shows a flowchart of the data transmission / reception step.

  In S601, the communication control circuit 222 issues a blood sugar level transmission command to the transmission circuit 221. The transmission circuit 221 that has received the blood sugar level transmission command repeatedly transmits the blood sugar level data transferred from the blood sugar level calculating unit 21 to the portable management terminal 3 for a predetermined transmission time (one second).

  In step S <b> 602, after the transmission circuit 221 has repeatedly transmitted for one second, the communication control circuit 222 issues a reception start command to the reception unit 23. The reception unit 23 that has received the reception start command continues to perform reception processing for a predetermined reception time (for example, 1.5 seconds). In step S603, it is determined whether the data received by the receiving unit 23 during the 1.5 second reception process in step S602 is a communication interruption command. If the received data is a communication interruption command, the process proceeds to S606 in order to receive a wireless communication completion notification for temporarily suspending and restarting the wireless communication. If the received data is not a communication interruption command, in S604, it is determined whether or not the data received by the receiving unit 23 during the 1.5 second reception process in S602 is a wireless communication completion notification. If the received data is a wireless communication completion notification, the data transmission / reception step ends. If the received data is not a wireless communication completion notification, the process proceeds to S605 to determine whether to retransmit the blood glucose level.

  In S605, it is determined whether or not the blood sugar level transmission processing in S601 and the data reception processing in S602 have been repeated a predetermined number of times (for example, five times). If the transmission process of S601 and the reception process of S602 are repeated five times, the data transmission / reception step ends. If the transmission process of S601 and the reception process of S602 are not repeated five times, the process proceeds to S601 in order to retransmit the blood glucose level.

  In S606, the communication control circuit 222 issues a reception start command to the reception unit 23. Then, the receiving unit 23 that has received the reception start command continues to perform reception processing for 1.5 seconds.

  In step S607, the data received during the 1.5 second reception process in step S606 determines a wireless communication completion notification. If the received data is a wireless communication completion notification, the process proceeds to S601 in order to resume transmission of blood glucose level data. If the received data is not a wireless communication completion notification, the process proceeds to S608 in order to determine whether or not to perform wireless communication completion notification reception processing again.

  In S608, it is determined whether or not the data reception process in S606 has been repeated a predetermined number of times (for example, 10 times). If the data reception process has been repeated 10 times, the process proceeds to S601 in order to retransmit the blood glucose level data. If the data reception process has not been repeated 10 times, the process proceeds to S606 in order to receive a wireless communication completion notification.

  FIG. 7 shows an example of the case where there are a plurality of biological information measuring devices and a plurality of portable management terminals in the first embodiment of the present invention, and two sets of biological information measuring devices (30a, 30b). ) And portable management terminals (40a, 40b). Such a situation assumes a case where a plurality of doctors and nurses who share and manage a large number of patients in a hospital or the like each own a portable management terminal.

  Normally, if two biological information measuring devices (30a, 30b) simultaneously perform wireless communication with the respective mobile management terminals (40a, 40b), the emitted radio waves interfere with each other. , 40b) cannot correctly receive the data transmitted from the biological information measuring devices (30a, 30b). Therefore, when one biological information measuring device 30a starts wireless communication with the portable management terminal 40a, the other biological information measuring device 30b does not start wireless communication with the portable management terminal 40b in order to avoid radio wave interference. I have to wait.

  However, the biological information measuring device 30b measures the blood glucose level of the user, and if the measured blood glucose level is an abnormal value (for example, 400 mg / dl or more), the blood glucose level is promptly transmitted to the portable management terminal 40b. Information must be transmitted and notified to a doctor or nurse who manages the user through the portable management terminal 40b. Therefore, the wireless communication of the biological information measuring device 30a already performing wireless communication is interrupted, and an abnormal blood glucose level is preferentially transmitted.

  In FIG. 7, while the biological information measuring device 30a wirelessly communicates the blood glucose level (for example, 98.2 mg / dl) to the portable management terminal 40a, the biological information measuring device 30b performs the blood glucose level (for example, 458 mg / dl). ) Is wirelessly communicated to the portable management terminal 40b.

First, operations of the biological information measuring device 30a and the portable management terminal 40a will be described.
The biological information measuring device 30a performs the blood glucose level measurement process 50a of the user A. Next, it is determined whether another device is performing wireless communication by performing reception processing 51a for a predetermined reception time (for example, 1.5 seconds).

  Further, at the stage of the reception process 51a in FIG. 9, since the other device is not performing wireless communication and a high level carrier wave is not detected, the biological information measuring device 30a determines that the other device is not performing wireless communication. If it is determined that the other device is not performing wireless communication, the biological information measuring device 30a transmits the measured blood glucose level information (normal value: 98.2 mg) to the portable management terminal 40a for a predetermined transmission time (for example, 1 second). / Dl) is transmitted wirelessly (transmission process 52a).

  In the mobile management terminal 40a, the mobile terminal periodically performs the reception process 60a (for example, 0.8 seconds) in order to reduce power consumption during wireless communication. (The same applies to the reception processes 61a to 67a). In the reception process 61a, blood glucose level information (normal value) is to be received from the biological information measuring device 30a, but at the same time, a communication interruption command from the biological information measuring device 30b is also received. End up. The transmission of the communication interruption command from the biological information measuring device 30b will be described later. When the one-second transmission process 52 ends, the biological information measuring device 30a performs a 1.5-second reception process 53a in order to receive a wireless communication completion notification from the portable management terminal 40a. Since the mobile management terminal 40a has failed to receive the blood glucose level in the reception process 61a, the mobile management terminal 40a does not transmit a wireless communication completion notification.

  As a result, since only the biological information measuring device 30b is transmitting while the biological information measuring device 30a is performing the receiving process 53a, the biological information measuring device 30a receives the biological information measuring device 30b in the receiving process 62a. The communication interruption command from will be received without interference.

  When the communication interruption command is received, the biological information measuring apparatus 30a waits for a wireless communication completion notification from the portable management terminal 40b, and performs a wireless communication interruption release waiting process 54a. When the wireless communication completion notification is received from the portable management terminal 40b, the biological information measuring device 30a performs the reception process 55a for 1.5 seconds, and confirms that no other device is performing wireless communication. The information measuring device 30a resumes the transmission of the blood glucose level information (normal value), which was interrupted earlier (transmission process 56a). After the one-second transmission process 56a, a 1.5-second reception process 57a is started to receive a wireless communication completion notification from the portable management terminal 40a. When the portable management terminal 40a receives the blood glucose level information (normal value) from the biological information measuring device 30a at the timing 66a, the biological information measuring device after a predetermined transmission start time 68a (for example, 1.2 seconds) has elapsed. Wireless communication completion notification 67a is repeatedly transmitted to 30a for a predetermined transmission time (for example, 0.3 seconds).

  When the biological information measuring device 30a receives the wireless communication completion notification, the series of blood glucose level information transmission processing ends.

  Next, operations of the biological information measuring device 30b and the portable management terminal 40b will be described. The biological information measuring device 30b performs the blood glucose level measurement process 50b of the user B. Next, it is confirmed whether another device is performing wireless communication by performing a reception process 51b for 1.5 seconds.

  In the case of FIG. 7, the biological information measuring device 30b determines that another device is performing wireless communication from the radio wave from which the biological information measuring device 30a transmits blood glucose level information (normal value: 98.2 mg / dl). To do. Further, since the biological information measuring device 30b calculates the blood glucose level of the abnormal value (458 mg / dl), the time required for the transmission process when transmitting the blood glucose level to interrupt the wireless communication of other devices is 1 second. The communication interruption command transmission processing 52b for a longer time (for example, 2 seconds) is performed, and the communication interruption command is repeatedly transmitted.

  After the communication interruption command transmission process 52b, the biological information measuring apparatus 30b enters the reception process 53b for 1.5 seconds and does not receive radio waves from other devices. Check. When the interruption of the wireless communication is confirmed, the biological information measuring device 30b enters the transmission process 54b for 1 second and repeatedly transmits the blood glucose level information (abnormal value: 458 mg / dl).

  Since the portable management terminal 40b receives the blood glucose level information (abnormal value: 458 mg / dl) in the reception process 64b, after the predetermined transmission start time 68b (for example, 1.2 seconds) elapses, the portable management terminal 40b receives 0. The wireless communication completion notification 65b is repeatedly transmitted for 3 seconds. After the transmission is completed, the blood glucose meter 30b enters the reception process 55b for 1.5 seconds, and when a wireless communication completion notification is received from the portable management terminal 40b, a series of blood glucose level information transmission processes ends.

  As described above, in the first embodiment of the present invention, when the measured blood glucose level is an abnormal value, the wireless communication status of the surrounding biological information measuring device is checked, and the wireless communication status is determined according to the wireless communication status. Thus, by transmitting a communication interruption command for interrupting wireless communication, it is possible to quickly transmit blood glucose level information that requires urgent.

  In the first embodiment, when a wireless communication interruption release waiting state is received by a communication interruption command from another biological information measuring device during transmission, a wireless communication completion notification is received from the corresponding mobile management terminal. However, the biometric information measuring apparatus that has performed wireless communication may restart the transmission by issuing a communication restart command. By doing so, it is possible to cancel the communication interruption even when the completion notification cannot be received due to an abnormality of the mobile management terminal.

  The biological information measuring device according to the present invention has a function of transmitting measured values to a medical device in an emergency by interrupting wireless communication of other biological information measuring devices in an environment where a plurality of biological information measuring devices exist. It is useful as a measuring instrument with a wireless function.
