[About the operation of the dispensing unit]
The operation of the dispensing unit 31 will be described with reference to FIGS. First, the filling operation of the liquid medicine 700 into the syringe 800 will be described based on FIG. 7, and then the medicine blending operation will be described based on FIG. Note that the timing of the operation described below is controlled by the control unit 31.

(Liquid drug filling operation)
First, as illustrated in FIG. 7A, the syringe 800 is conveyed to the liquid medicine supply unit 311. At this time, the piston portion 802 of the syringe 800 is press-fitted to the deepest portion (the needle 803 side) of the cylinder portion 801. Syringe 800 is arranged so that needle 803 is located in front of rubber member 3h (liquid medicine storage member 3k).

  The syringe transport mechanism 313 moves the syringe 800 in the direction of the rubber member 3h as it is, inserts the needle 803 into the rubber member 3h and inserts it into the medicine bottle 800, and further, the tip of the needle 803 (with a hole) The syringe 800 is moved until it is disposed in the hollow portion of the drug storage member 3k (see FIG. 7B).

  Next, the piston moving mechanism 314 moves the piston portion 802 in the direction opposite to the needle 803 while holding the cylinder portion 801 and holding the piston rear end portion 802a. That is, the piston portion 802 that is at the deepest portion of the cylinder portion 801 is moved in the direction of the opening of the cylinder portion 801. Accordingly, the liquid medicine 700 in the medicine storage member 3k is sucked into the cylinder portion 801 from the tip of the needle 803. At this time, the liquid medicine 700 is replenished to the medicine storage member 3k through the tube 3g. The piston moving mechanism 314 stops the operation by moving the piston portion 802 by a predetermined distance (see FIG. 7C). Thereby, the liquid medicine 700 is filled in the syringe 800.

  Finally, the syringe transport mechanism 313 moves the syringe 800 in the direction opposite to the liquid medicine supply unit 311 (see FIG. 7D). Even if the needle 803 comes out of the rubber member 3h, the through hole formed by the needle 803 is closed by the elasticity of the rubber member 83h, so that the liquid medicine 700 in the medicine reservoir member 3k does not leak.

(Pharmaceutical preparation operation)
The preparation of the medicine by the dispensing unit 31 is performed using the liquid medicine 700 filled in the syringe 800 by the above liquid medicine filling operation.

  First, the syringe 800 is conveyed to the medicine holding unit 312. FIG. 8A shows the positional relationship between the medicine bottle 900 held by the medicine holding unit 312 and the syringe 800 conveyed. The syringe 800 is disposed so that the needle 803 is positioned above the rubber member 902.

  The syringe transport mechanism 313 moves the syringe 800 in the direction of the rubber member 902 in that state, inserts the needle 803 into the rubber member 902, and the tip of the needle 803 is disposed in a hollow portion in the medicine bottle 900. The syringe 800 is moved to (see FIG. 8B). At this time, it is desirable to position the tip of the needle 803 near the bottom of the medicine bottle 900.

  Next, the piston moving mechanism 314 moves the piston portion 802 in the direction of the needle 803 (downward) while holding the cylinder portion 801 and holding the piston rear end portion 802a. Thereby, the liquid medicine 700 in the cylinder part 801 is injected into the medicine bottle 900 (see FIG. 8C).

  Subsequently, the piston moving mechanism 314 moves the piston portion 802 upward. Thereby, the mixture 700 ′ of the medicine and liquid medicine 700 stored in the medicine bottle 900 is sucked into the cylinder portion 801 (see FIG. 8D).

  The piston moving mechanism 314 repeatedly moves the piston part 802 up and down a predetermined number of times to repeat the suction of the contents in the medicine bottle 900 to the cylinder part 801 and the injection from the cylinder part 801 to the medicine bottle 900 (FIG. 8 (C), (D), (E)). In this process, the powder or solid medicine stored in the medicine bottle 900 is dissolved in the liquid medicine 700 to create a mixed medicine 710.

  After the piston part 802 has been moved up and down a predetermined number of times, the piston moving mechanism 314 moves the piston part 802 upward from the lowest position and sucks the created mixed medicine 710 from the medicine bottle 900 by a predetermined amount ( (See FIG. 8F).

  When the mixed medicine 710 is aspirated, the syringe transport mechanism 313 moves the syringe 800 upward and reverses the direction up and down to point the needle 803 upward (see FIG. 8G). At this time, the piston moving mechanism 314 is also moved together with the syringe 800. In this state, the piston moving mechanism 314 moves the piston portion 802 upward, and discharges air present in the cylinder portion 801 from the tip of the needle 803. Finally, the cap 804 is attached to the syringe 800 by the cap attaching / detaching mechanism 35 described later. This completes the medicine blending operation.

  In the above example, when the direction of the syringe 800 is turned upside down, the position of the piston moving mechanism 314 is changed, but another piston is moved to a position below the syringe 800 shown in FIG. A mechanism 314 may be provided.

The flow charts of FIGS. 14, 15, and 16 show an example of the usage pattern when a medicine to be administered (mixed) to a patient is prepared and filled into a syringe. In the stage before the start of dispensing, only the filling amount information 219 is stored in the information storage unit 21 of the control unit 2. The flowchart of FIG. 17 represents an example of the usage pattern after dispensing and filling of the syringe are completed. The flowcharts of FIGS. 18 and 19 show an example of a usage pattern when a drug is administered to a patient. The flowchart of FIG. 20 represents an example of a usage pattern after a drug is administered to a patient.

[Preparation of medicine and filling into syringe: FIGS. 14 to 16]
First, a patient ID is input from the patient information input unit 25 of the control unit 2 (S1). The control unit 20 controls the communication unit 26 to transmit a command for searching the electronic medical record information associated with the input patient ID to the medical information database 1000, and obtain the target electronic medical record information (S2). ). The control unit 20 stores the medication history information 217 and the patient contraindication information 218 included in the electronic medical record information in the information storage unit 21 as patient information 21b (S3).

  Next, the user inserts the medicine bottle 900 into the medicine input unit 3b of the dispensing unit 3 (S4). The charged medicine bottle 900 is placed on the placing table of the medicine bottle holding unit 312 and is held by a plurality of wheels. When the medicine bottle holding unit 312 rotates the medicine bottle 900, the identification information reading unit 37 reads the medicine ID (identification information) recorded in the barcode 903 (S5). The control unit 30 of the dispensing unit 3 controls the communication unit 26 to transmit the read medicine identification ID to the control unit 2.

  The control unit 20 of the control unit 2 controls the communication unit 26 to transmit a command for searching for drug information associated with the drug ID to the medical information database 1000 and acquire target drug information (S6). ). The control unit 20 stores the storable period information 210, the dose allowable range information 211, the concentration allowable range information 212, the drug use information 213, the drug contraindication information 214, the injection rate allowable range information 215, and the injection amount allowable range included in the drug information. Information 216 information is stored in the storage unit 21 as medicine information 21a (S7).

  As described above, all information shown in FIG. 3 is stored in the information storage unit 21. It should be noted that information indicating the above-described medicine preparation method (dissolution method), information indicating a method for confirming the amount of medicine stored in the medicine bottle, and the like may be further stored.

  Among the information stored in the information storage unit 21, the control unit 20 of the control unit 2 includes the dose tolerance information 211, the concentration tolerance information 212, the drug use information 213, the drug contraindication information 214, the medication history information 217, and the patient contraindications. Information 218 and filling amount information 219 are transmitted to dispensing unit 3 (S8). At this time, information indicating a drug dissolution method, information indicating a drug storage amount confirmation method, and the like may be sent simultaneously.

(Check if it is a contraindicated drug)
The dispensing unit 3 receives information from the control unit 2 and stores it in the information storage unit 30A. The control unit 30 determines whether or not the medicine ID recorded in the barcode 903 read in step S5 is included in the patient contraindication information 218 (S9). If included (S9; Y), the control unit 30 displays a warning message (notification information) on the display unit 3e (S31). The determination result may be transmitted from the dispensing unit 3 to the control unit 2 and the notification information may be output using the monitor 221 or the audio output unit 222 (the same applies hereinafter). The user recognizes the occurrence of an abnormality from the notification information and takes measures such as changing to another drug.

  When the medicine ID is not included in the patient contraindication information 218 (S9; N), the control unit 30 determines whether the medicine in the medicine bottle 900 is contraindicated based on the medicine contraindication information 214 and the medication history information 217. (S10). That is, it is determined whether or not the drug ID read in step S5 matches the drug ID of a drug that requires attention in combination with the drug indicated in the drug contraindication information 214. When it is determined that it is contraindicated (S10; Y), the control unit 30 displays a warning message on the display unit 3e (S31).

(Confirmation of drug amount)
On the other hand, when it is determined that it is not contraindicated (S10; N), the control unit 30 controls the medicine bottle storage amount measuring unit 36 to measure the weight of the medicine bottle 900, and the measured value and the amount allowable range information 211 Based on the above, it is determined whether or not an appropriate amount of medicine is stored in the medicine bottle 900 (S11). At this time, for example, the control unit 30 subtracts the weight of the medicine bottle 900 itself from the measured weight value to calculate the stored amount of the medicine, and the calculation result is the amount allowable range information 211 (information indicating the weight of the medicine itself). ). When the total weight including the weight of the medicine bottle 900 itself is used as the quantity allowable range information 211, the control unit 30 determines whether the measured value of the weight is included in the allowable range indicated in the quantity allowable range information 211. .

  When it is determined that an appropriate amount of medicine is not stored in the medicine bottle 900 (S11; N), the control unit 30 displays a warning message on the display unit 3e (S31). Upon receiving this warning message, the user takes out the medicine bottle 900 and inserts a new medicine bottle 900.

(Confirmation of specified drug concentration)
On the other hand, when it is determined that an appropriate amount of medicine is stored in the medicine bottle 900 (S11; Y), the user operates the operation unit 3d to designate the concentration of this medicine (S12). The control unit 30 determines whether or not the designated drug concentration is included in the allowable range indicated in the concentration allowable range information 212 (S13).

  When it is determined that the designated drug concentration is not included in the allowable range (S13; N), the control unit 30 displays a warning message on the display unit 3e (S31).

  When it is determined that the specified drug concentration is within the allowable range (S13; Y), the user sets the drug storage member 3f storing the liquid drug 700 (saline) on the above-mentioned stand, One end of the tube 3g is attached, and the other end is attached to a predetermined attachment position of the housing 3a of the dispensing unit 3 (S14).

(Confirmation of remaining liquid medicine)
The control unit 30 controls the liquid medicine remaining amount detection unit 38 to detect the remaining amount of the liquid medicine 700 stored in the medicine storage member 3f, and compares the detection result with a predetermined value (S15). When the detected remaining amount is equal to or less than the predetermined value (S15; N), a warning message is displayed on the display unit 3e (S31).

(Dispensing)
When the detected remaining amount exceeds a predetermined value (S15; Y), the user loads the syringe 800 on the syringe loading unit 33 (S16). The cap attaching / detaching mechanism 35 detaches the cap 804 of the syringe 800 (S17). The syringe 800 is transported to the liquid medicine supply unit 311 by the syringe transport mechanism 313. The syringe transport mechanism 313 and the piston moving mechanism 314 fill the syringe 800 with the liquid medicine 700 in the manner shown in FIG. 7 (S18).

  The syringe 800 filled with the liquid medicine 700 is transported to the medicine bottle holder 312 by the syringe transport mechanism 313. The syringe transport mechanism 313 and the piston moving mechanism 314 dissolve the medicine in the medicine bottle 900 in the liquid medicine 700 as shown in FIGS. 8A to 8E (S19). Then, the piston moving mechanism 314 fills the syringe 800 with the mixed medicine 710 in the manner shown in FIG. 8F (S20). At this time, the syringe 800 is filled with the mixed medicine 710 by the amount indicated by the filling amount information 219. Here, the dispensing unit 3 sends a signal to the control unit 2, acquires the time counted by the time counting unit 23, and stores it in the information storage unit 30A as the time (dispensing time) when dispensing was performed (S21).

Next, as shown in FIG. 8G, the syringe transport mechanism 313 vertically inverts the syringe 800, and the piston moving mechanism 314 press-fits the piston portion 802 to discharge the air in the cylinder portion 801. (S22). Then, as shown in FIG. 8H, the cap attaching / detaching mechanism 35 attaches the cap 804 to the syringe 800 (S23). The syringe 800 with the cap 804 attached is conveyed to the drug concentration meter side unit 34 by the syringe conveyance mechanism 313.

(Confirmation of concentration of medicine filled in syringe)
The control unit 30 controls the drug concentration meter side unit 34 to measure the drug concentration of the mixed drug 710 filled in the syringe 800 (S24), and the measured value is included in the service range indicated in the concentration tolerance range information 212. It is judged whether or not (S25). When it is determined that it is not included (S25; N), the control unit 30 displays a warning message on the display unit 3e (S31).

(Label processing)
When it is determined that the measured value of the drug concentration falls within the allowable range (S25; Y), the syringe 800 is transported to the label processing unit 32 by the syringe transport mechanism 313. The identification information recording unit 321 refers to the drug use information 213, and indicates the drug ID, drug name, drug concentration read in step S5, the barcode indicating the dispensing time obtained in step S21, and the like. The character string is recorded on the label L (S26).

  At this time, when the use of the medicine shown in the medicine use information 213 is for mixed injection, as shown in FIG. 9B, a label or the like is attached to the label L having the information recording portion Lc and the reattachment portion Ld. Record. The information recording part Lc and the reattachment part Ld are connected in a detachable state. The identification information recording unit 321 records a barcode in the barcode recording unit La of the information recording unit Lc, and records character string information in the information display unit Lb. On the other hand, when the medicine is not used for mixed injection, as shown in FIG. 9A, the barcode is recorded in the barcode recording part La of the label L, and the character string information is recorded in the information display part Lb.

  Next, the label affixing unit 322 affixes the label L on which information is recorded to the syringe 800 (S27). When the normal label L shown in FIG. 9A is used, the entire label L is attached to the syringe 800 as shown in FIG. On the other hand, when the co-injection label L shown in FIG. 9B is used, as shown in FIG. 10B, only the covering member on the back surface of the information recording unit Lc is peeled off and attached to the syringe 800. . In addition, the adhesive agent is apply | coated to the back surface of the resticking part Ld, and the coating | coated member is affixed as it is. At the time of mixed injection, the user peels off the label L from the syringe 800, peels off the covering member of the reattachment portion Ld, and sticks the label L to the drip bag.

  The syringe 800 to which the label L is attached is placed in the syringe takeout part 3c and taken out by the user (S28).

  The control unit 30 sends information such as the drug ID read in step S5, the drug concentration specified in step S12, the dispensing time obtained in step S21, the drug concentration measured in step S24, and the like via the communication unit 39. To the control unit 2 (S29).

  The control unit 20 of the control unit 20 causes the information storage unit 21 to store dispensing information such as a specified value and a measured value of the drug concentration, a dispensing time, a drug name, and a filling amount in association with the drug ID (S30). This completes the preparation of the medicine and the filling of the medicine into the syringe.

[After filling the dispensing and syringe: Fig. 17]
Next, referring to FIG. 17, the usage pattern after the above-described preparation of the medicine and filling into the syringe will be described. Here, the case where the medicine is not administered to the patient within the storage period is described.

  When dispensing and filling of the syringe are completed, the control unit 20 of the control unit 2 displays the dispensing information stored in step S30 of FIG. 16 on the monitor 221 (S41). Dispensing information is transmitted to the control unit 2 every time dispensing and filling into the syringe are performed by the dispensing unit 3, and a list of these dispensing information is displayed on the monitor 221. In this list, the medicine ID, the medicine name, the medicine concentration, the dispensing time, the storable period shown in the storable period information 210, and the like are displayed. By referring to this list, doctors and nurses can grasp the presence of dispensed drugs and the storage period of drugs.

  Based on the time measured by the time measuring unit 23 and the storable period information 210, the control unit 20 detects that, for example, 15 minutes before the storable period shown in the storable period information 210 (S42) The display color of the display content related to the medicine in the list displayed in 221 is switched to a different color (S43). At this time, a warning message may be displayed on the monitor 221 or a warning voice may be output from the voice output unit 222. Doctors and nurses can know that the expiration date of the medicine is approaching from such notification information.

  When the control unit 20 detects that the storable time limit has arrived based on the time measured by the time measuring unit and the storable period information 210 (S44), the control unit 20 displays a warning message on the monitor 221 to determine the expiration date of the medicine. The fact that it has passed is notified (S45). This warning message is displayed until the syringe 800 filled with the medicine is discarded in the disposer unit 5 (S46; N).

  When the doctor or nurse recognizes that the expiration date has passed by the notification information and discards the syringe 800 in the storage unit 51 of the disposer unit 5 (S46; Y), the identification information recording unit 51 is attached to the syringe 800. The barcode of the labeled label L is read (S47). The read information is transmitted to the control unit 2 by the communication unit 52.

  The control unit 20 of the control unit 2 deletes the display content related to the medicine having the same medicine ID as the medicine ID included in the information from the disposer unit 5 from the monitor 221 (S48). Information indicating that the medicine has been discarded (for example, character string information such as “discarded”) may be displayed on the monitor 221.

[Drug administration: FIGS. 18 and 19]
Next, with reference to FIG. 18 and FIG. 19, a usage pattern when administering the mixed medicine 710 filled in the syringe 800 to the patient will be described.

  When a nurse or the like attaches the syringe 800 to the syringe placement portion 4a of the injector unit 4 (S51), the syringe 800 is rotated by the syringe rotation mechanism 46. The identification information reading unit 45 reads the barcode of the label L attached to the syringe 800 (S52). The control unit 40 transmits the medicine ID recorded in the read barcode to the control unit 2 (S53).

(Check storage period)
The control unit 20 of the control unit 2 reads out the storable period information 210 of the medicine information 21a associated with the medicine ID received from the injector unit 4 and the dispensing time (see step S30 in FIG. 16) from the information storage unit 21. (S54). Moreover, the control part 20 acquires the time (medication time) which the time measuring part 23 has timed when medicine ID is received from the injector unit 4 (S55).

  The storage period calculation unit 201 calculates a time interval between the dispensing time and the medication time (S56). The determination unit 202 determines whether or not the calculated time interval exceeds the storable period indicated in the storable period information 210 (S57). When it is determined that the number has exceeded (S57; Y), the control unit 20 controls the notification unit 22 to output notification information, and transmits a signal to the injector unit 4 to turn on (blink) the LED 44. Then, the notification information is output (S73). Further, the control unit 40 of the injector unit 4 does not accept the input signal from the injection start / stop button 43 based on the signal from the control unit 2 (S74). Thereby, administration of the mixed medicine 710 is prohibited.

  When it is determined that the calculated time interval is within the storable period (S57; N), the control unit 20 stores the drug information 21a and patient information 217 associated with the drug ID received from the injector unit 4 in the injector unit 4. Transmit (S58). The information transmitted here includes at least drug contraindication information 214, injection rate allowable range information 215, injection amount allowable range information 216, medication history information 217, and patient contraindication information 218. The control unit 40 of the injector unit 4 stores information from the control unit 2 in the information storage unit 47.

(Confirmation of injection conditions)
The doctor or nurse operates the injection condition setting unit 42 to set the injection speed and the injection amount of the mixed medicine 710 (S59). The control unit 40 determines whether the set injection rate is included in the allowable range shown in the injection rate allowable range information 215 (S60). If not included (S60; N), the control unit 40 performs notification by turning on (flashing) the LED 44 (S75). The determination result may be transmitted from the injector unit 4 to the control unit 2 and the notification information may be output using the monitor 221 or the audio output unit 222 (the same applies hereinafter). The user recognizes the occurrence of an abnormality from this notification information and takes measures such as changing the injection rate.

  When the setting value of the injection rate is included in the allowable range (S60; Y), the control unit 40 determines whether the set injection amount is included in the allowable range indicated in the injection amount allowable range information 216 (S61). ). If it is not included (S61; N), the LED 44 is turned on (flashing) to notify (S75). The user takes measures such as changing the injection rate.

(Check if it is a contraindicated drug)
When it is determined that the set value of the injection amount is included in the allowable range (S61; Y), the control unit 40 displays the medicine ID recorded in the barcode read in step S52 in the patient contraindication information 218. It is determined whether it is included (S62). If it is included (S62; Y), the LED 44 is turned on (flashing) to notify (S75). The user takes measures such as changing to another medicine based on the notification information.

  When the drug ID is not included in the patient contraindication information 218 (S62; N), the control unit 30 contradicts the mixed drug 710 filled in the syringe 800 based on the drug contraindication information 214 and the medication history information 217 (concomitant use). (S63). When it is determined that it is contraindicated (S63; Y), the control unit 40 displays a warning message on the display unit 3e (S75).

  On the other hand, when it is determined that it is not contraindicated (S63; N), when the user operates the injection start / stop button 43 (S64), the control unit 40 controls the pressing mechanism unit 4B to start injection of the mixed medicine 710. (S65). Corresponding to the start of injection of the mixed medicine 710, information such as the injection speed and the injection amount is transmitted from the injector unit 4 to the control unit 2 together with the medicine ID (S66).

  The control unit 20 of the control unit 2 receives information from the injector unit 4 and acquires information such as the drug concentration from the dispensing information (see step S30 in FIG. 16) associated with the drug ID, and the time measuring unit 23. The information storage unit 21 stores information (injection start information) such as an injection rate, an injection amount, a drug concentration, an injection start time, and a drug name in association with the drug ID (S67).

  In addition, the control unit 20 transmits information such as a medicine ID and a patient ID of the patient to the medical accounting computer 2000 (S68). Based on the received information, the medical accounting computer 2000 calculates a price for the administration of the mixed drug 710 and stores it as medical information of the patient in the medical accounting database 3000 (S69).

  When the injection of the mixed medicine 710 is completed (S70), information such as a medicine ID, an injection speed, and an injection amount is transmitted from the injector unit 4 to the control unit 2 (S71). The control unit 20 of the control unit 2 receives information from the injector unit 4 and associates information (injection end information) such as an injection speed, an injection amount, a drug concentration, an injection end time, and a drug name with the drug ID. The information is stored in the information storage unit 21 (S72). The process at the time of drug administration is thus completed.

[After drug administration: FIG. 20]
With reference to FIG. 20, a usage pattern after the medicine is administered by the injector unit 4 will be described.

  When the medication is completed, the nurse or the like removes the syringe 800 from the injector unit 4 and discards it in the storage unit 50 of the disposer unit 5 (S81). The identification information recording unit 51 reads the barcode of the label L attached to the syringe 800 (S82). The read information is transmitted to the control unit 2 by the communication unit 52.

  A list of dispensing information of each medicine is displayed on the monitor 221 of the control unit 2 (see step S41 in FIG. 17). The control unit 20 searches for the medicine having the same medicine ID as the medicine ID included in the information from the disposer unit 5, and deletes the dispensing information of the medicine from the monitor 221 (S83). In addition, the control unit 20 stores information indicating that the medicine has been discarded (discarded information) in the information storage unit 21 in association with the medicine ID (S84).

  For the deleted medicine, the monitoring of the storage period of the medicine is stopped and no notification is given even if the storage period expires.

  Thereby, dispensing information, injection start information, injection end information, and discarded information are stored in the information storage unit 21 in association with the drug ID. The control unit 2 transmits these pieces of information together with the patient ID to the medical information database 1000 and adds the information to the medical chart information 1001 of the patient (S85). The injection start information and the injection end information are examples of “administration information” in the present invention.

[Action / Effect]
According to the medicine administration system 1 according to the present embodiment as described above, the following actions and effects are exhibited.

  This medicine administration system 1 reads a barcode 903 attached to a medicine bottle 900 when the medicine is prepared by the dispensing unit 3. The dispensing unit 3 records the created medicine ID of the mixed medicine 710 on the label L based on the read medicine ID, and affixes the label L to the syringe 800.

  The control unit 2 acquires necessary information (drug information) from the medical information database 1000 based on the read medicine ID or a separately input patient ID, and stores the information in the information storage unit 21 in association with the medicine ID.

  The injector unit 4 reads the barcode (drug ID) recorded on the label L attached to the syringe 800 when administering the mixed medicine 710 filled in the syringe 800 to the patient.

  The control unit 2 reads out the medicine information associated with the medicine ID read from the label L of the syringe 800, and outputs notification information based on the medicine information. In addition, the dispensing unit 3 and the injector unit 4 cause the control unit 20 of the control unit 2 to read out the drug information associated with the drug ID, and outputs notification information based on the drug information.

  At the time of dispensing, whether the drug to be formulated is not contraindicated for the patient (step S9), whether combined use with drugs previously administered to the patient is not contraindicated (step S10), in the drug bottle 900 Is an appropriate amount of medicine stored (for example, is it empty) (step S11), is the drug concentration designated by the user appropriate (step S13), or is the remaining amount of the liquid medicine 700 sufficient (step S15)? ), Whether or not the concentration of the dispensed mixed medicine 710 is appropriate is determined. When the determination result indicates inappropriateness, notification information indicating that fact is output, and the preparation of the mixed drug is prohibited and the process is terminated.

  After dispensing, the storage period of the prepared mixed medicine 710 is monitored, a notification is given when the storage period is approaching, and a warning is given to doctors and the like (steps S42 and S43), and the storage period has elapsed. In some cases, a warning message to the effect that the mixed medicine 710 should be discarded is output (steps S44 and S45).

  At the time of administration of the mixed drug 710, whether the storage period of the mixed drug 710 has not elapsed (step S57), the setting value of the injection rate is appropriate (step S60), or the setting value of the injection amount is appropriate (step S60) Step S61), whether this mixed drug 710 is not contraindicated for the patient (Step S62), or is not contraindicated in combination with drugs previously administered to the patient (Step S63). The And when a judgment result shows improperness, the alerting | reporting information which shows that is output.

  Further, the dispensing information is displayed on the monitor 221 until the prepared mixed medicine 710 is administered to the patient and discarded.

  Therefore, according to the drug administration system 1 according to the present embodiment, the syringe is filled with only physiological saline in the case where the drug is forgotten to be recorded despite the dissolution date and time, or when the dissolution operation is temporarily interrupted. Such as mistakes that cause mistakes and misuse of syringes when using multiple drugs are effectively prevented.

  Further, according to the drug administration system 1, it is possible to effectively avoid the occurrence of human errors such as misreading, error, and misunderstanding of drug names, concentrations, dosages, and the like in dissolution work, filling work, and administration work. Thereby, it is possible to greatly reduce the risk of occurrence of mistakes such as administration of a drug different from the intended purpose, administration of contraindicated drugs, or wrong dosages due to wrong dissolution concentrations.

  As described above, according to the drug administration system 1 of the present embodiment, it is possible to prevent an administration error of a drug used by dispensing in a medical field. It aims to provide possible technology.

  Furthermore, this medicine administration system 1 is used to inject information such as designated values and measured values of medicine concentration, dispensing time, medicine name, filling amount, and injection speed, injection volume, drug concentration, injection start time, drug name, etc. The start information and the injection end information are stored in the information storage unit 21 (steps S30, S67, S72). Further, these pieces of information are added to the medical record information 1001 of the medical information database 1000 after the medicine is discarded. Therefore, it is possible to prevent an error in recording information at the time of dispensing or drug administration, which is effective in reducing the risk of occurrence of the aforementioned human error.

  In addition, when the mixed drug 710 to be administered exceeds the storable period, the drug administration system 1 acts to prohibit the administration of the mixed drug 710 (step S74). Therefore, even if the user has overlooked the notification information, the expired mixed medicine 710 is not erroneously administered even if the user instructs the start of injection.

  In addition, since the dispensing unit 2 records the dispensing time of the mixed medicine 710 on the label L, the doctor or nurse looks at the dispensing time on the label L, and mixes the syringe 800 filled. It can be recognized when the medicine 710 was created. Note that the time when the mixed medicine 710 can be stored may be recorded on the label L.

  When the used syringe 800 is discarded in the disposer unit 5, the barcode of the label L attached to the syringe 800 is read. When the control unit 2 receives the information from the disposer unit 5, the control unit 2 stops monitoring the storage period of the mixed medicine 710 and does not perform any subsequent notification, so that unnecessary notification information is output. There is nothing to do.

  The control unit 2 receives information from the disposer unit 5 and deletes the dispensing information of the mixed medicine 710 displayed on the monitor 221 from the list. Therefore, the list on the monitor 221 displays the dispensing information of the drug waiting for administration, the drug being administered, and the drug not discarded after administration. By referring to this list, the user can easily grasp which medicine is currently being handled, so that the possibility of occurrence of an administration error or the like is greatly reduced.

[Modification]
The configuration detailed above is only a specific example for suitably carrying out the present invention. Therefore, arbitrary modifications within the scope of the present invention can be appropriately made.

  The drug administration system 1 of the above embodiment is configured by the individual control unit 2, the dispensing unit 3, the injector unit 4 and the disposer unit 5, but two or more of these units 2 to 5 are integrated. It may be configured. Further, it is not necessary to provide the disposer unit 5.

  Further, the injector unit 4 does not need to be provided when the medicine injection is performed manually. However, even in that case, a reading device (second reading means) for reading the identification information (bar code; drug ID) attached to the syringe used for drug injection is necessary. The doctor or the like starts the drug injection after reading the identification information attached to the syringe with the reading device. When the injection is completed, the identification information is read again.

  It is also possible to apply a dispensing unit that performs only drug preparation. In that case, a medicine bottle storing the prepared mixed medicine is carried out from the dispensing unit. The user manually fills the syringe with the mixed medicine by, for example, inserting a syringe needle into the medicine bottle.

  In addition, the operation of checking the contents of the medicine bottle is not limited to that by measuring the medicine amount (step S11) in the above embodiment. For example, when a member made of metal or the like indicating that the medicine bottle is not opened is provided on the cap, it is determined whether or not the contents of the medicine bottle are still used by detecting the presence or absence of the member. be able to. When this configuration is adopted, it is desirable to add a mechanism for removing the member. Further, it may be determined whether or not the rubber member on the cap has been used in the past by detecting whether or not there is a hole in the rubber member.

  Further, similarly to the case where the medication is prohibited when the time limit of the mixed medicine has passed (step S74), the infusion conditions are inappropriate (S60; N, S61; N), or the contraindicated medicine (S62). Y, S63; Y) may also be prohibited. However, especially during surgery, if the drug is not urgently administered, it may endanger the patient's life, and it is considered desirable not to prohibit medication in these cases.

  As shown in FIG. 7, the dispensing unit 2 of the above embodiment is configured to dissolve the drug by taking the liquid drug 700 filled in the syringe 800 into and out of the drug bottle 900. As another configuration for dissolving the drug in the same manner, first, the syringe 800 is moved by moving the piston 802 relative to the cylinder 801 while the cylinder 801 of the syringe 800 is fixed by the piston moving mechanism 314. While the liquid medicine 700 filled in the medicine bottle 900 is poured into the medicine bottle 900 and the medicine bottle 900 is swung or rotated, a stirring mechanism (stirring means) for stirring the contents can be provided. . The stirring mechanism includes an actuator for swinging the medicine bottle 900, a motor for rotating, and the like.

  In addition, information indicating the state of each medicine can be displayed in a list display of medicine dispensing information. For example, information indicating a waiting state for administration is displayed for a medicine that has not yet been input with information from the injector unit 4, and information is input from the injector unit 4, but information is not yet input from the disposer unit 5. Information indicating the state of waiting for disposal can be displayed on medicines that have not been received.

  Further, by providing a weight measuring device at the bottom of the storage unit 50 of the disposer unit 5, it is possible to determine whether the syringe is used and discarded, or is a syringe discarded without being used. . For example, when a syringe is newly discarded, the weight of this syringe is calculated by comparing the weights before and after the disposal. And based on the filling amount (obtained from the filling amount information 219 specified by the medicine ID) initially filled in this syringe and the calculated weight, whether this syringe was used or not used Can be judged. This process is performed by the control unit 20 of the control unit 2, for example.

  In the above embodiment, since the mixed drug is prepared by dissolving the powdered drug or the like in the drug bottle 900 with physiological saline (liquid drug 700), the mixed drug is essentially the same as the original drug. Therefore, the drug ID of the original drug was used as it is for the drug ID of the mixed drug. However, when the original drug and the mixed drug are essentially different, it is desirable to give a drug ID different from the original drug. In that case, a character string formed by connecting the respective drug IDs of the drug 1 and the drug 2 to be prepared may be used as the drug ID of the mixed drug.

  Moreover, since there are a finite number of types of drugs used for preparation, the types of mixed drugs formed by arbitrarily combining them are also limited. Therefore, drug IDs can be set in advance for these finite number of mixed drugs. For example, if the drug IDs of the drugs 1 to 9 to be prepared are “1111”, “2222”,..., “9999”, the drug ID of the mixed drug consisting of the drugs 1 and 2 is “ In “Aaaa”, the drug ID of the mixed drug consisting of drugs 1 and 3 is set to “bbbb”, the drug ID of the mixed drug consisting of drugs 1 and 4 is set to “cccc”, and so on. A medicine ID of a mixed medicine created by arbitrarily blending two or more of them can be set in advance.

  Further, the user may manually attach the label on which the medicine ID or the like is recorded to the syringe. In that case, the syringe filled with the mixed medicine and the label are carried out from the dispensing unit.

  In addition, when filling the syringe with the mixed medicine created by the dispensing unit 3 manually or automatically, when starting the filling operation, the time interval (elapsed time) from the dispensing time is calculated, and the calculation is performed. It is also possible to determine whether the result exceeds the storable period indicated in the storable period information 210 and to notify when it is determined that the result has exceeded.

  More specifically, the medicine ID is recorded in the means for storing the mixed medicine created by the dispensing unit 3, and when the mixed medicine is filled in the syringe, the recorded medicine ID is read and stored in the storage period information 210. Can be configured to obtain

  In addition, when using the container (for example, medicine bottle 900) already attached with medicine ID (barcode 903) as means for storing the mixed medicine, it is not necessary to record the medicine ID again. In addition, when reading the medicine ID at the time of filling, for example, the identification information reading unit 37 of the dispensing unit 3 can be used when it is automatically performed. Reading means such as a reader can be used.
