  Inside the insulin pump 2 of FIG. 1, a medicine syringe 14 (FIG. 3) containing insulin is detachably attached to a medicine syringe mounting portion 15 (FIG. 3). As shown in FIG. Insulin in the drug syringe 14 is administered to the patient via a tube 16 and a needle 17 (an example of a drug injection needle) connected to the mounting unit 15.

  Note that the needle 17 is inserted into the patient's abdomen and subcutaneous fat in the stomach, and the insulin pump 2 can continue to administer a minute amount of insulin automatically for 24 hours.

  FIG. 3 shows a block diagram of the insulin pump 2.

  As shown in FIG. 3, a communication unit 18 that communicates with the measuring instrument 1 is connected to the control unit 19. The control unit 19 is connected to a storage unit 20 for storing the dose of insulin received from the measuring device 1 through communication, and further connected to a motor 21 for administering insulin corresponding to the dose of insulin. Has been.

  The motor 21 is connected to a drug syringe mounting part 15 to which the drug syringe 14 is mounted, and the drug syringe mounting part 15 is connected to the drug administration port 2a (FIG. 1). Furthermore, as shown in FIG. 1, a tube 16 is connected to the drug administration port 2a. The drug syringe 14 is constituted by, for example, a cylindrical syringe (not shown) and a movable plunger (not shown). When the motor 21 operates the plunger, the insulin sealed in the syringe is tubed. 16 to send.

  Further, the battery 22, the power switch 23, and the display unit 24 are connected to the control unit 19.

  Returning to FIG. 1 again, the insulin monitor 3 (an example of a drug administration monitor) in the present embodiment will be described.

  As shown in FIG. 1, the insulin monitor 3 is provided in the middle of a tube 16 that connects the insulin pump 2 and the needle 17.

  FIG. 4 is a cross-sectional view of the insulin monitor 3, which has a main body case 25. The main body case 25 has a drug inlet 26 connected to the drug administration port 2a of the insulin pump 2 via the tube 16 on one end side, and a needle 17 (drug injection needle) on the other end side. A drug flow path 28 having a drug outlet 27 connected to the drug injection port 17a (FIG. 1).

  The drug channel 28 is formed of the same material as the tube 16 in a hollow cylindrical shape, and is connected to the tube 16. Insulin flows through the drug flow path 28.

  Further, a flow rate sensor 29 that detects the flow rate of insulin (an example of a drug) flowing through the drug flow path 28 is provided in the main body case 25.

  Further, the flow rate sensor 29 described above is provided on the downstream side of the drug discharge channel 27A of the drug channel 28 (that is, on the drug outlet 27 side).

  The flow sensor 29 is a non-wetted electromagnetic flow sensor, and measures the flow rate by measuring the voltage generated by the conductive fluid flowing in the magnetic field. That is, as shown in FIG. 4, the two flow sensors 29 sandwich the tube 16 from the outside of the tube 16 forming the drug flow path 28, and generate a magnetic field in the sandwiched portion. When insulin flows through the drug flow path 28 of the tube 16 in the magnetic field, a voltage is generated.

  The flow path switch 30 is connected to the control unit 32 via the flow path switching unit 34.

  Note that a communication unit 35 that communicates with the measuring instrument 1 is connected to the control unit 32, and a battery 36 is further connected.

  In the above configuration, the operation of the measuring instrument 1, the insulin pump 2, and the insulin monitor 3 will be described below with reference to the flowcharts of FIG. 1, FIG. 5, FIG. 6, and FIG.

  First, there are two types of insulin administration methods by the insulin pump 2, and they are called bazar (always administration) and bolus (temporary administration), respectively. FIG. 6 is a diagram for explaining these bazars and boluses.

  First, bazar (A in FIG. 6) is a method in which insulin is always administered in small amounts (for example, 24 hours), which is a basic secretion of a healthy person.

  On the other hand, the bolus (B in FIG. 6) is a method in which a predetermined amount of insulin is temporarily administered when the blood glucose level after a meal rises, which corresponds to additional secretion of a healthy person.

  In these bazars and boluses, insulin is administered to the patient in units.

  This unit is a unit indicating the dose of insulin, and the insulin carbo (carbo represents the amount of carbohydrate, for example, 1 carb = 10 grams of carbohydrate) multiplied by the amount of carbohydrate from the meal is administered. Amount. In addition, the value of this insulin carbo ratio changes with people.

  As a specific example, when a person with an insulin / carbo ratio of 1.5 eats a carbohydrate of 200 grams (= 20 carbo), 1.5 (insulin / carbo ratio) × 20 (carbo) = Administration of 30 units of insulin is required.

  First, the description when the administration method of the insulin pump 2 is bazar (always administration) will be described using the flowchart of FIG.

  At the time of the bazar, the insulin pump 2 is instructed in advance by the patient's operation. For example, as shown in FIG. 9, the insulin dose is displayed as (insulin dose 0.25 U) on the display unit 4 of the measuring instrument 1, and the patient instructs the insulin pump 2 about this insulin dose.

  The instructed insulin dose is communicated to the insulin pump 2 and the insulin monitor 3 via the communication unit 18 and the control unit 19 of the measuring device 1. This time, for example, insulin is administered to the patient at 0.25 units per hour.

  The insulin pump 2 receives this insulin dose via the communication unit 18 in FIG. 3 and stores it in the storage unit 20.

  At the time of administration, the control unit 19 of the insulin pump 2 calculates a delivery amount (that is, a dose per hour) according to the insulin dose, and controls the motor 21 according to the calculated amount. The motor 21 starts delivery of insulin sealed in the syringe to the tube 16 by operating a plunger (not shown) of the drug syringe 14 mounted on the drug syringe mounting unit 15.

  On the other hand, in the insulin monitor 3, the flow rate monitoring unit 31 receives the insulin dose transmitted by the measuring device 1 via the communication unit 35 and the control unit 32.

  The flow rate monitoring unit 31 receives the insulin dose, determines that the bolus administration has been started by the insulin pump 2, notifies the intermittent drive unit 33 of the start of monitoring, and monitors from S1 in FIG. Start processing.

  When the insulin pump 2 starts to administer insulin in the bazar (normally administered), the insulin monitor 3 starts to monitor the insulin dose. At this time, the insulin monitor 3 determines whether the administration method by the insulin pump 2 is bazar or bolus (temporary administration). As described above, this determination is made based on the dose of insulin transmitted by the measuring instrument 1 (S2 in FIG. 7).

  In this bazar monitoring, the intermittent drive unit 33 in FIG. 5 checks the value of the flow sensor 29 using the flow monitoring unit 31 at every predetermined monitoring interval (for example, once per minute in the bazar monitoring). To do. Then, the flow rates measured at predetermined monitoring intervals are integrated (S3 in FIG. 7).

  Next, the flow rate monitoring unit 31 determines whether or not the flow rate per unit time is within a specified range based on the integrated amount (S4 in FIG. 7).

  If the flow rate per unit time is larger than the specified range, the amount of insulin administered by the insulin pump 2 is excessive, so the control unit 32 of the insulin monitor 3 uses the communication unit 35 to connect to the measuring device 1. Notify overdose of insulin. In the measuring instrument 1, the control unit 9 receives this excess notification via the communication unit 12, and, for example, as shown in FIG. 10 (a), the display unit 4 of the measuring instrument 1 (insulin administration error confirms the state of the insulin pump). )) To inform the patient of excessive insulin administration.

  The patient who sees this display operates the insulin pump 2 to cancel this error state.

  Furthermore, the control unit 32 of the insulin monitor 3 notifies the insulin pump 2 of an excessive dose of insulin using the communication unit 35. In the insulin pump 2, the control unit 19 receives this excess notification via the communication unit 18, and for example, as shown in FIG. 10 (b), the display unit 24 of the insulin pump 2 confirms the insulin administration error state of the insulin pump. Please display).

  That is, the patient can know not only the display of the measuring instrument 1 but also the display of the insulin pump 2 that there is an excessive dose of insulin during the bazar. Thereafter, the patient operates the insulin pump 2 to cancel this error state (S5 in FIG. 7).

  Note that after the process of S5 in FIG. 7 is completed, the process returns to S2 of FIG.

  On the other hand, when the flow rate monitoring unit 31 determines in S4 of FIG. 7 that the flow rate per unit time is within the specified range, the process returns to S2 of FIG. 7 to determine whether the state of the insulin pump 2 is bazar. It will be determined again whether it is a bolus, and monitoring of the dosage of insulin will be continued.

  Next, explanation will be given when the administration method of the insulin pump 2 is bolus (temporary administration).

  First, monitoring by the insulin monitor 3 is started in S1 of FIG. At this time, as described above, the bazar is monitored in the normal state.

  Here, for example, after the patient has eaten, the blood glucose level rises, so that the bolus is administered.

  More specifically, in FIG. 1, as described above, the blood glucose level of the patient is measured by the measurement unit 10 (FIG. 2) of the measuring device 1, and the dose of insulin corresponding to this blood glucose level is calculated as the dose. Calculated by the unit 11 (FIG. 2), for example, (Insulin dosage 30U) is displayed on the display unit 4 as shown in FIG.

  Next, the measurement device 1 communicates the calculated dose of insulin to the insulin pump 2 and the insulin monitor 3 using the communication unit 12 by the operation of the patient.

  The insulin pump 2 receives this insulin dose via the communication unit 18 in FIG. 3 and stores it in the storage unit 20. The control unit 19 calculates a delivery amount (that is, a dose per hour) according to the insulin dose, and controls the motor 21 according to the calculated amount. The motor 21 starts delivery of insulin sealed in the syringe to the tube 16 by operating a plunger (not shown) of the drug syringe 14 mounted on the drug syringe mounting unit 15.

  On the other hand, in the insulin monitor 3, the flow rate monitoring unit 31 receives the insulin dose transmitted from the measuring device 1 via the communication unit 35.

  Then, the flow rate monitoring unit 31 receives the insulin dose, determines that the bolus administration has been started by the insulin pump 2, and notifies the intermittent drive unit 33 of the monitoring start (S2 in FIG. 7). The monitoring process starts from S1 in FIG.

  FIG. 8 is a flowchart showing the bolus monitoring process.

  In S1 of FIG. 8, the insulin monitor 3 waits for the bolus to start.

  Specifically, the intermittent drive unit 33 issues a monitoring instruction to the flow rate monitoring unit 31 at regular intervals, and in accordance with this monitoring instruction, the flow rate monitoring unit 31 determines the amount of insulin that the insulin pump 2 sends to the tube 16. The flow rate sensor 29 is used for monitoring.

  In this bolus monitoring, the intermittent drive unit 33 in FIG. 5 makes the bolus monitoring interval of the flow rate monitoring unit 31 shorter than the bazar monitoring interval (for example, once per minute), for example, in 1 second. Once.

  Then, at every predetermined monitoring interval (for example, once per second), the intermittent drive unit 33 uses the flow rate monitoring unit 31 to check the value of the flow rate sensor 29. At this time, when the measured value suddenly increases compared to the previous value, the flow rate monitoring unit 31 determines that the bolus has started.

  Further, the intermittent drive unit 33 confirms the value of the flow rate sensor 29 using the flow rate monitoring unit 31 at every predetermined monitoring interval (for example, once per second) and integrates the flow rate (FIG. 8). S2).

  The flow rate monitoring unit 31 determines an excessive dose using the integrated amount of the flow rate (S3 in FIG. 8). Specifically, when the integrated amount per predetermined time exceeds a predetermined value, it is determined that the dose is excessive, and the control unit 32 is notified of the excessive dose. Upon receiving this excessive notification, the control unit 32 operates the flow channel switch 30 using the flow channel switching unit 34, and changes the drug flow channel 28 of FIG. 4 from the drug outlet 27 side to the drug discharge flow channel. Switch to 27A (S4 in FIG. 8).

  For this reason, insulin is discharged out of the insulin monitor 3, and excessive insulin is not administered into the patient's body. Accordingly, appropriate administration of the drug can be performed, and as a result, appropriate utility of the drug can be exhibited.

  Next, the control unit 32 of the insulin monitor 3 notifies the measuring device 1 of the excessive dose of insulin using the communication unit 35. In the measuring instrument 1, the control unit 9 receives this excess notification via the communication unit 12, and, for example, as shown in FIG. 10 (a), the display unit 4 of the measuring instrument 1 (insulin administration error confirms the state of the insulin pump). Please) and inform the patient of excessive insulin administration (S5 in FIG. 8).

  The patient who sees this display operates the insulin pump 2 to cancel this error state (S6 in FIG. 8).

  When the dose is not excessive in S3 of FIG. 8, the flow rate monitoring unit 31 determines whether or not the bolus has ended. This determination is made by comparing the current measured value of the flow sensor 29 with the measured value of the previous flow sensor 29, and when the difference is within a predetermined value, it is determined that the bolus is continuing, as shown in FIG. Returning to S2, the monitoring is continued (S7 in FIG. 8).

  On the other hand, when the difference between the measured values is equal to or greater than the predetermined value (that is, when the current measured value is rapidly smaller than the immediately preceding measured value), the flow rate monitoring unit 31 determines that the bolus has ended.

  Thereafter, the flow rate monitoring unit 31 determines whether or not the bolus has been appropriately implemented. That is, it is determined whether or not the dose of insulin was too small.

  If the integrated amount of the flow rate is equal to or less than the specified value, the flow rate monitoring unit 31 determines that the bolus is inappropriate and the dose of insulin is too small (S8 in FIG. 8).

  Then, the control unit 32 of the insulin monitoring device 3 notifies the measuring device 1 of an insufficient amount of insulin using the communication unit 35. In the measuring instrument 1, the control unit 9 receives this under notification via the communication unit 12, and confirms the state of the insulin administration error insulin pump on the display unit 4 of the measuring instrument 1, for example, as shown in FIG. Please)) and inform the patient of insufficient insulin administration (S9 in FIG. 8).

  The patient who sees this display operates the insulin pump 2 to cancel this error state (S10 in FIG. 8).

  When the dose is not too low at S8 in FIG. 8, the process returns to S2 in FIG. 7, and it is determined again whether the state of the insulin pump 2 is bazar or bolus, and the insulin dose is monitored. Will be continued.

  As described above, in this embodiment, since the dose of the insulin pump 2 is detected not only by the insulin pump 2 but also by the insulin monitor 3, appropriate administration of insulin can be performed, and as a result, The appropriate utility of the drug can be exerted.

  Further, in the present embodiment, the medicine flow path 27A is connected to the drug flow path 28, and the flow path switch 30 is provided in the drug discharge flow path 27A.
