The control unit 18 controls the image displayed on the screen 17 a based on various types of information stored in the storage unit 19. In this embodiment, a case where information on a drug solution to be injected into the infusion bag 21, audit information, information on a patient to which the prepared drug solution is applied, etc. is displayed on the screen 17a of the information presentation unit 17 will be described. The information on the drug solution includes information necessary for preparation of the drug solution, such as the type of drug solution, the dose of the drug solution, and the preparation procedure of the drug solution. Note that only one of the information related to the chemical solution and the audit information may be displayed on the information presentation unit 17.

By providing the information presentation unit 17, the drug solution preparation support system 10 can visually present information to the operator such as the type of drug solution to be injected into the infusion bag 21 and the mixing preparation order of drug solutions. It becomes. Therefore, the operator can easily and accurately confirm the information necessary for the preparation of the drug solution. In addition, the operator can prepare the drug solution efficiently.

Subsequently, the base unit 13 will be described. As shown in FIG. 1, the base unit 13 is integrated with the medicine bottle weight measurement unit 14, the infusion bag weight measurement unit 15, and the cradle unit 16. Further, the base unit 13 includes a work table (mixing preparation area) 13 a disposed adjacent to the medicine bottle weight measurement unit 14 and the infusion bag weight measurement unit 15. On this workbench 13a, workers such as a nurse and a pharmacist can carry out a preparation operation of a drug solution. Further, as described above, the information presentation unit 17 is installed in the base unit 13, and the control unit 18 and the storage unit 19 are built in the housing of the base unit 13. Therefore, with this configuration, the chemical solution preparation supporting device 11 can be made compact. Therefore, the worker can carry the drug solution preparation support device 11 and prepare the drug solution at any place. The medical fluid preparation support system may be configured such that the medicine bottle weight measurement unit 14, the infusion bag weight measurement unit 15, the cradle unit 16, and the information presentation unit 17 are separated from the base unit 13.

Subsequently, the medical information database 12 will be described. In the medical fluid preparation support system 10, medical information such as information on medical fluid, audit information, patient information and the like is transmitted and received between the medical fluid preparation support device 11 and the medical information database 12. With this configuration, various types of information can be fetched from the medical information database 12 and stored (stored) in the storage unit 19 as necessary. Further, audit information stored in the storage unit 19 can be accumulated in the medical information database 12 as medical information. By transmitting and receiving various types of information between the chemical solution preparation supporting device 11 and the medical information database 12 as described above, the capacity of the storage unit 19 incorporated in the base unit 13 can be reduced. Therefore, the chemical solution preparation supporting device 11 can be further miniaturized.

Based on the information on the drug solution stored in the storage unit 19, the control unit 18 displays a full-size photograph image (real-shot image) of each medicine bottle 20 containing the drug solution to be injected into the infusion bag 21 based on the information on the drug solution stored in the storage unit 19. The mixed preparation order is displayed on the screen 17a of FIG. Therefore, the information on the drug solution includes data of a photographed image.

As described above, by arranging and displaying the photographed images in the mixed preparation order, a worker such as a nurse or a pharmacist can arrange and arrange the medicine bottles 20 in the mixed preparation order while comparing with the photographed images. Therefore, the worker can visually check the type of medicine (the type of medicine bottle). Therefore, for example, even when it is necessary to stock medicine bottles containing medicines of similar names, it is possible to prevent mistakes in the selection of medicine bottles and an error in the arrangement order of the medicine bottles. Furthermore, since the medicine bottles can be arranged in the order of mixing and preparation, it is possible to prevent an error in the order of suctioning the medicine (order of mixing medicines).

The medical fluid preparation support system 10 includes a reading unit 24 that reads prescription identification information (prescription ID) in order to fetch information on a medical fluid from the medical information database 12. The prescription ID read by the reading unit 24 is stored in the storage unit 19 by the control unit 18.

The reading unit 24 has a shape of a folder for holding a sheet (hereinafter, referred to as “prescription”) 25 on which a prescription is printed. Therefore, the reading unit 24 reads the prescription ID printed on the prescription 25 inserted in the folder.

By providing the reading unit 24 for reading out the prescription identification information as described above, the medical information can be easily read from the medical information database 12. Further, by providing the folder of the prescription 25 on the back of the information presentation unit 17, it is possible to reduce the risk that the prescription 25 becomes contaminated with the medical solution etc. and the characters can not be read when the medical solution is prepared.

Note that instead of the reading unit 24 that reads the prescription ID, a reading unit that reads information on the drug solution and information on the drug printed on the surface of the prescription 25 is provided, and the information read by the reading unit is stored in the storage unit 19 Alternatively, instead of the reading unit that reads information related to the prescription ID and the medical solution, an input unit that can input information related to the prescription ID and the medical solution is provided, and the information input by the input unit is stored in the storage unit 19 It is good also as composition which makes it memorize.

The chemical solution preparation support system 10 also includes a camera 26. The camera 26 is used to authenticate the worker. That is, the control unit 18 performs authentication by comparing the image of the worker taken by the camera 26 with the image of the worker stored in the storage unit 19. In this way, only persons registered in advance can be permitted to work. Moreover, this camera 26 can also be used for authentication of the medicine bottle 20 containing the chemical | medical solution to be used. That is, the control unit 18 performs authentication by comparing the image of the medicine bottle 20 taken by the camera 26 with the photographed image included in the information on the liquid medicine. In this way, it is possible to prevent an error in the selection of medicine bottles. Further, this camera 26 can also be used to record an image of a chemical solution preparation operation.

Although not shown, a reflection type photo sensor may be embedded at each position where the medicine bottle of the medicine bottle weight measurement unit 14 is placed, and a signal generated by the reflection type photo sensor may be transmitted to the control unit 18. In this way, even if a plurality of medicine bottles 20 having the same weight are placed on the medicine bottle mounting section 14a, is the medicine bottles 20 picked up from the medicine bottle mounting section 14a according to the mixing preparation order A control unit based on a signal generated by a reflection type photo sensor as to whether or not the medicine bottle 20 picked up from the medicine bottle mounting unit 14a is returned to the original position on the medicine bottle mounting unit 14a. It becomes possible to judge 18. Therefore, it is possible to reliably prevent an error such as a mistake in the medicine bottle.

Although not shown, the liquid medicine preparation supporting device 11 displays an LED (Light Emitting Diode) display corresponding to each position where the medicine bottle weight measurement unit 14 is placed in the vicinity of the medicine bottle weight measurement unit 14. A department is provided. The light emission of the LED display unit is controlled by the control unit 18. That is, the control unit 18 causes the LED display unit corresponding to the medicine bottle 20 to be suctioned to emit light. By the light emission of the LED display unit, it is possible to explicitly instruct the operator about the medicine bottle 20 to be sucked.

Next, the basic operation of the drug solution preparation support system 10 according to this embodiment will be described.

First, a worker such as a nurse or a pharmacist inserts the prescription 25 into the reading unit 24 provided on the back of the information presentation unit 17. On the prescription 25, information on the patient, information on a drug solution applied to the patient, a prescription ID and the like are printed. When the prescription 25 is inserted into the reading unit 24, the reading unit 24 reads the prescription ID printed on the prescription 25. The read prescription ID is stored in the storage unit 19 by the control unit 18. The prescription ID stored in the storage unit 19 is transmitted by the control unit 18 to the medical information database 12. The medical information database 12 transmits information on a patient corresponding to the received prescription ID, information on a drug solution, and the like. The transmitted information on the patient and the drug solution is stored in the storage unit 19 by the control unit 18.

Thereafter, the control unit 18 causes the screen 17 a of the information presentation unit 17 to display an instruction corresponding to each step of the liquid preparation operation based on the patient information stored in the storage unit 19 and the information on the medical solution. Therefore, the worker can perform the preparation operation of the drug solution in accordance with the instruction displayed on the screen 17 a of the information presentation unit 17.

FIG. 3 is a diagram showing an example of an instruction displayed on the screen 17 a of the information presentation unit 17.

Even in this case, it is possible to support an audit as to whether or not there is an error in picking up the medicine bottle (medical solution).

Subsequently, an audit when the medicine bottle 20 is returned to the medicine bottle mounting portion 14a will be described. FIG. 6 is a view showing an example of a change in weight measured by the vial weight measuring unit 14 when each medicine bottle 20 from which the medicines A, B and C are sucked is returned to the medicine bottle placement unit 14a. .

In the initial state where the medicine bottles 20 containing the medicines A, B and C are sorted, the total weight W3 of the medicine bottle A to the medicine bottle C is measured by the medicine bottle weight measurement unit 14 as shown in FIG. There is. First, the operator picks up the medicine bottle A from the medicine bottle mounting portion 14a in order to suction the liquid medicine A. Then, after suctioning the drug solution A, the operator returns the medicine bottle 20 from which the drug solution A is sucked to the original position on the medicine bottle mounting portion 14a. As a result, as shown in FIG. 6, the weight W5 is measured by the medicine bottle weight measurement unit 14.

Then, the control unit 18 recognizes the measured amount of decrease ΔW7 as the suctioned weight of the liquid medicine A and stores it in the storage unit 19. Furthermore, the control unit 18 compares the suctioned weight ΔW7 of the recognized drug solution A with the data (predetermined value) of the suctioned weight of the drug solution A previously stored in the storage unit 19 and stores the comparison result. Remember to Thus, the suctioned weight ΔW7 of the measured drug solution A and the comparison result are stored in the storage unit 19 as audit information.

When the data on the suctioned weight of the drug solution is included in the information on the drug solution, the included data may be used. Alternatively, the control unit 18 may calculate the suction weight of the chemical solution from the data of the dose of the chemical solution contained in the information on the chemical solution, and store the data of the suction weight of the calculated chemical solution in the storage unit 19. The control unit 18 may calculate the suction amount of the chemical solution from the suction weight of the measured chemical solution, and compare the calculated suction amount with the data of the dose of the chemical solution contained in the information on the chemical solution.

Next, the operator picks up the medicine bottle B from the medicine bottle mounting portion 14a in order to suction the liquid medicine B. Then, after suctioning the drug solution B, the operator returns the medicine bottle 20 from which the drug solution B has been sucked back to the original position on the medicine bottle mounting portion 14a. As a result, as shown in FIG. 6, the weight W7 is measured by the medicine bottle weight measurement unit 14. At this time, the control unit 18 measures the amount of decrease ΔW8 (= W5-W7) from the weight W5 measured when the vial A is returned. Then, the control unit 18 recognizes the measured amount of decrease ΔW 8 as the suctioned weight of the chemical solution B, and stores it in the storage unit 19.

As a result, as shown in FIG. 6, the weight W9 is measured by the medicine bottle weight measurement unit 14. At this time, the control unit 18 measures the amount of reduction ΔW9 (= W7−W9) from the weight W7 measured when the vial B is returned. Then, the control unit 18 recognizes the measured amount of decrease ΔW 9 as the suctioned weight of the drug solution C and stores it in the storage unit 19. Further, the control unit 18 compares the suctioned weight ΔW 9 of the recognized drug solution C with the data (predetermined value) of the suctioned weight of the drug solution C previously stored in the storage unit 19 and stores the comparison result. Remember to Thus, the suctioned weight ΔW9 of the measured drug solution C and the comparison result are stored in the storage unit 19 as audit information.

Then, the control unit 18 recognizes the measured amount of increase ΔW10 as the weight of the medicine bottle 20 from which the drug solution A is sucked, and stores it in the storage unit 19. Furthermore, the control unit 18 recognizes the weight ΔW10 of the recognized medicine bottle A after suction and the data (predetermined value) of the weight of the medicine bottle in which the medicine solution A has been suctioned by a predetermined dose previously stored in the storage unit 19. And the comparison result is stored in the storage unit 19. Thus, the measured weight ΔW10 of the medicine bottle A after suction and the comparison result are stored in the storage unit 19 as audit information.

If the data on the weight of the medicine bottle in which the drug solution has been aspirated by a predetermined dose is included in the information on the drug solution, the data included in the information may be used. Alternatively, the control unit 18 may analyze the weight of the medicine bottle from which the medicine solution has been sucked by a predetermined dose from the information on the medicine solution, and store the analyzed data in the storage unit 19. The weight of the medicine bottle from which the drug solution has been sucked by a predetermined dose can be obtained, for example, by taking the difference between the initial weight of the drug bottle and the suction weight of the drug solution.

As described above, based on the amount of increase in weight measured by the vial weight measurement unit 14, the weight of the medicine bottle 20 from which the medicine was aspirated is measured, thereby supporting the comparison audit of the type of medicine aspirated. can do.

Further, when the control unit 18 recognizes that the measured weight of the medicine bottle 20 after the suction of the drug solution does not match the data of the weight of the medicine bottle after the drug solution suction, which is previously stored in the storage unit 19. , Generate suction error information. Not agreeing means not agreeing within the error range. The suction error information indicates at least one of the fact that there is an error in the suction amount, that there is an error in the type of the suctioned drug solution, and that the drug solution has been spilled. The suction error information may be displayed on the screen 17 a of the information presentation unit 17. Alternatively, the chemical solution preparation support system 10 may be provided with a device (not shown) that sounds an alarm sound corresponding to the suction error information generated by the control unit 18.

Since the comparison audit of the type of medicine bottle (medical solution) described above is performed in the order of mixing and preparation of the medical solution, it is also possible to support an audit as to whether the mixing and preparation order of the medical solution is correct.

Further, the control unit 18 counts the number of times of change in weight measured by the medicine bottle weight measurement unit 14 when the medicine solution is aspirated from each medicine bottle 20 containing the medicine solutions A, B, C. Based on the counting result, the number of vials 20 returned onto the vial placement unit 14a is measured. The measured data is stored in the storage unit 19 by the control unit 18. Then, the control unit 18 compares the measured number of medicine bottles 20 with the data (predetermined value) of the number of medicine bottles previously stored in the storage unit 19 to obtain all the medicines on the medicine bottle placement unit 14a. It is determined whether the medicine bottle 20 has been returned.

As described above, the drug solution preparation support system 10 can support an audit as to whether or not there is an error in the suction amount of the drug solution or the like.

Subsequently, for various audits based on the change in weight measured by the infusion bag weight measurement unit 15, an example of injecting the aspirated drug solution into the infusion bag 21 every time the drug solution is aspirated from one medicine bottle 20 Explain to.

When a drug solution is injected from the syringe 23a into the infusion bag 21 placed on the infusion bag placement unit 15a, the weight measured by the infusion bag weight measurement unit 15 increases according to the injection amount. The control unit 18 measures the injection weight of the drug solution injected into the infusion bag 21 based on the increase in weight measured by the infusion bag weight measurement unit 15. The measured injection weight of the drug solution is stored in the storage unit 19 by the control unit 18. Then, the control unit 18 compares the measured injection weight of the chemical solution with the data (predetermined value) of the injection weight of the chemical solution previously stored in the storage unit 19 and stores the comparison result in the storage unit 19. . Thus, the measured injection weight of the drug solution and the comparison result are stored in the storage unit 19 as audit information.

When the data of the injection weight of the chemical solution is included in the information on the chemical solution, the data included in the information may be used. Alternatively, the control unit 18 may calculate the injection weight of the chemical solution from the data of the dose of the chemical solution contained in the information on the chemical solution, and store the calculated data of the injection weight of the chemical solution in the storage unit 19 . The control unit 18 may calculate the injection amount of the chemical solution from the measured injection weight of the chemical solution, and compare the calculated injection amount with the data of the dose of the chemical solution contained in the information on the chemical solution. Alternatively, even if the data of the suction amount of the drug solution or the suction weight data of the drug solution measured when suctioning the drug solution from the medicine bottle 20 to the syringe 23a is used as the injection amount data of the drug solution or data of injection weight of the drug solution.

Further, the control unit 18 recognizes that the measured injection weight of the drug solution or the injection amount of the drug solution does not match the injection weight of the drug solution or the dose data (predetermined value) of the drug solution previously stored in the storage unit 19. If it does, it will generate injection error information. Here, "do not match" means that they do not match within the error range. The injection error information indicates at least one of the fact that there is an error in the injection amount, that there is an error in the type of the injected liquid drug, that the liquid drug remains in the syringe 23a, and that the liquid drug has been spilled. The injection error information may be displayed on the screen 17 a of the information presentation unit 17. Alternatively, the chemical solution preparation support system 10 may be provided with a device (not shown) that sounds an alarm sound corresponding to the injection error information generated by the control unit 18.

Since the measurement audit of the drug solution injected into the infusion bag described above is performed in the order of mixing and preparation of drug solutions, it is possible to support the audit as to whether or not the mixing and preparation order of drug solutions is correct.

Further, the control unit 18 counts the number of changes in weight measured by the infusion bag weight measurement unit 15, and measures the number of times the drug solution is injected into the infusion bag 21 based on the counting result. The measured data is stored in the storage unit 19 by the control unit 18. Then, the control unit 18 compares the measured number of injections of the drug solution with the data (predetermined value) of the number of medicine bottles previously stored in the storage unit 19 and stores the comparison result in the storage unit 19. . As described above, the measured number of times of injection of the drug solution and the comparison result are stored in the storage unit 19 as audit information.

The data on the number of medicine bottles may use the data on the number of medicines contained in the information on medicines, or the control unit 18 may use the data on the number of medicines analyzed from the information on medicines Alternatively, data on the number of medicines measured when the medicine bottles 20 are placed on the medicine bottle placement unit 14a may be used, or the medicine solution is sucked from the medicine bottles 20 prepared on the medicine bottle placement unit 14a. Data on the number of chemical solutions measured at that time may be used.

As described above, by counting the number of changes in weight measured by the infusion bag weight measurement unit 15, it is possible to support an audit of the number of injections of the drug solution (counting audit of drug solution).

In addition, when the control unit 18 recognizes that the measured number of times of injection of the chemical solution does not match the data of the number of medicine bottles previously stored in the storage unit 19, the number of times of injection of the chemical solution is insufficient. Generate counting error information indicating that. The counting error information may be displayed on the screen 17 a of the information presenting unit 17. Alternatively, the chemical solution preparation support system 10 may be provided with a device (not shown) that sounds an alarm sound corresponding to the counting error information generated by the control unit 18.

As described above, the chemical solution preparation support system 10 can support an audit as to whether or not there is an error in the injection amount of the chemical solution or the like.

In addition, although the case where the chemical | medical solution which was attracted | sucked was inject | poured into the infusion bag 21 whenever it aspirated the chemical | medical solution from one medicine bottle 20 was demonstrated here, after suctioning a chemical | medical solution from several medicine bottles into the syringe 23a Also in the case of injecting a plurality of times aspirated drug solution into the infusion bag 21 at a time from the syringe 23a, similarly, the measurement audit of the injected drug solution, the comparison audit of the type of the injected drug solution, the mixing preparation order of the drug solution Support the audit of In these audit processes, the total dose or total weight of all the drug solutions aspirated into the syringe 23a multiple times is used. Further, in this case, since the number of injections of the drug solution and the number of medicine bottles do not match, data of the number of injections of the drug solution needs to be stored in the storage unit 19 to support audit of the injection number of drug solutions . When the data on the number of times of injection of the chemical solution is included in the information on the chemical solution, the included data may be used. Alternatively, the control unit 18 may analyze the number of times of injection of the chemical solution from the information on the chemical solution, and store the data of the number of times of injection of the analyzed chemical solution in the storage unit 19. For example, the control unit 18 can analyze the number of times of injection of the chemical solution from the data of the mixing and preparation procedure of the chemical solution included in the information on the chemical solution.

Subsequently, various audits based on the weight measured by the cradle unit 16 will be described by taking, as an example, a case where the suctioned drug solution is injected into the infusion bag 21 every time the drug solution is sucked from one medicine bottle 20.

The syringe drive device 23 is held by the operator's hand when suctioning a drug solution from the medicine bottle 20 or when injecting a drug solution into the infusion bag 21, and is not held by the cradle unit 16.

When the operator sucks the drug solution into the syringe 23a and then causes the cradle unit 16 to hold the syringe drive device 23 before injecting the drug solution into the infusion solution bag 21, according to the amount of drug solution sucked into the syringe 23a. , The weight of the syringe drive 23 increases from the initial weight. The initial weight of the syringe drive device 23 is the weight when the inside of the syringe 23a is empty. The control unit 18 measures the suctioned weight of the drug solution sucked into the syringe 23a based on the weight measured by the cradle unit 16. The measured suction weight is stored in the storage unit 19 by the control unit 18. Then, the control unit 18 compares the measured suctioned weight of the drug solution with the data of the suctioned weight of the drug solution previously stored in the storage unit 19, and stores the comparison result in the storage unit 19. Thus, the suctioned weight of the measured drug solution and the comparison result are stored in the storage unit 19 as audit information.

When the data on the suctioned weight of the drug solution is included in the information on the drug solution, the included data may be used. Alternatively, the control unit 18 may calculate the suction weight of the chemical solution from the data of the dose of the chemical solution contained in the information on the chemical solution, and store the calculated data of the suction weight of the chemical solution in the storage unit 19 . The control unit 18 may calculate the suction amount of the chemical solution from the suction weight of the measured chemical solution, and compare the calculated suction amount with the data of the dose of the chemical solution contained in the information on the chemical solution. Alternatively, as the data of the suction amount of the drug solution or the data of the suction weight of the drug solution, the data of the suction amount of the drug solution or the data of the suction weight of the drug solution measured based on the change in weight measured by the medicine bottle weight measurement unit 14 You may use.

As described above, by measuring the suction weight of the drug solution or the suction amount of the drug solution based on the weight measured by the cradle unit 16, the measurement audit of the drug solution sucked in the syringe 23a, or suction in the syringe 23a It is possible to support the verification audit of the type of chemical solution.

In addition, the control unit 18 does not match the measured suctioned weight of the chemical solution or the suctioned amount of the chemical solution with the data of the suctioned weight of the chemical solution or the dose data (predetermined value) of the chemical solution previously stored in the storage unit 19. Generates suction error information when it recognizes Here, "does not match" means that they do not match within the tolerance. The suction error information indicates at least one of the fact that there is an error in the suction amount, that there is an error in the type of the suctioned drug solution, and that the drug solution has been spilled. The suction error information may be displayed on the screen 17 a of the information presentation unit 17. Alternatively, the chemical solution preparation support system 10 may be provided with a device (not shown) that sounds an alarm sound corresponding to the suction error information generated by the control unit 18.

Since the measurement audit of the drug solution sucked into the syringe 23a described above is performed in the order of mixing and preparation of the drug solution, it is also possible to support the audit as to whether the suction order of the drug solution is correct.

Further, the control unit 18 counts the number of times of measurement of the weight by the cradle unit 16, and measures the number of times of injecting the medical fluid from the syringe 23a into the infusion bag based on the counting result. The measured data is stored in the storage unit 19 by the control unit 18. Then, the control unit 18 compares the measured number of injections of the drug solution with the data (predetermined value) of the number of medicine bottles previously stored in the storage unit 19 and stores the comparison result in the storage unit 19. . As described above, the measured number of times of injection of the drug solution and the comparison result are stored in the storage unit 19 as audit information.

As described above, by counting the number of times of measurement of the weight by the cradle unit 16, it is possible to support the number of times of injection of the drug solution (counting audit of the drug solution).

In addition, although the case where the chemical | medical solution which was attracted | sucked was inject | poured into the infusion bag 21 whenever it aspirated the chemical | medical solution from one medicine bottle 20 was demonstrated here, after suctioning a chemical | medical solution from several medicine bottles into the syringe 23a Similarly, in the case of measuring the weight of the syringe drive device 23, it is possible to support the measurement audit of the suctioned drug solution, the check audit of the type of the drug solution sucked, and the audit of the mixing preparation order of the drug solution. In these audit processes, the total dose or total weight of all the drug solutions aspirated into the syringe 23a multiple times is used. In addition, when the number of times of chemical solution injection is audited, data of the number of times of chemical solution injection stored in the storage unit is used.

Subsequently, an inspection will be described as to whether or not the drug solution remains in the syringe 23a after the drug solution is injected into the infusion bag 21. When the operator causes the cradle unit 16 to hold the syringe drive unit 23 after injecting the drug solution into the infusion bag 21, the control unit 18 controls the weight measured by the cradle unit 16 to be the initial weight of the syringe drive unit 23. It is determined whether or not they match. Then, the control unit 18 generates the determination result as audit information.

As described above, based on the weight measured by the cradle unit 16, it is possible to support an audit as to whether or not all the drug solution sucked into the syringe 23a has been injected into the infusion solution bag 21.

The control unit 18 also generates remaining error information when recognizing that the drug solution remains in the syringe 23a. The remaining error information may be displayed on the screen 17 a of the information presentation unit 17. Alternatively, the chemical solution preparation support system 10 may be provided with a device (not shown) that sounds an alarm sound corresponding to the remaining error information generated by the control unit 18.

As described above, according to the drug solution preparation support system 10 according to the present embodiment, it is possible to reliably prevent an error in taking a medicine bottle, an error in suction amount of drug solution, and the like. Therefore, according to the drug solution preparation support system 10, it is possible to effectively prevent operation errors (dispensing errors) such as mixing procedure order of drug solution and measurement error of drug solution, and to realize safe and accurate preparation of drug solution.

Further, the chemical solution preparation support system 10 automatically and reliably generates audit information. Therefore, according to the drug solution preparation support system 10, the drug solution preparation work can be made more efficient.

Further, according to the drug solution preparation support system 10, it is possible to immediately notify the operator when an operation error such as an error in taking a medicine bottle or a measurement error of a drug solution occurs. Therefore, according to the drug solution preparation support system 10, it is not necessary to waste the drug solution (medicine bottle) and the infusion bag, and the cost for preparing the drug solution can be reduced. For example, if a measurement error of the drug solution first sucked into the syringe is detected before injecting the drug solution into the infusion bag, the medicine bottle intended for suction of the drug solution thereafter and the infusion bag are not discarded. It is

In addition, since the drug solution preparation support system 10 performs not only the weight measured by the vial weight measuring unit 14 but also the weight measured by the infusion bag weight measuring unit 15 and the cradle unit 16, the medicine is inspected. It is possible to prevent double or triple operation errors such as mistaking of a bottle or an error in the amount of chemical solution. Therefore, according to the chemical solution preparation support system 10, it is possible to prepare a safer and more accurate chemical solution.

Further, in addition to the reduction in weight when the medicine bottle 20 is taken out of the medicine bottle mounting unit 14a, the medicine solution preparation support system 10 returns the medicine bottle 20 from which the medicine is sucked to the medicine bottle mounting unit 14a. Since the amount of increase in weight at the time of being taken is also measured, it is possible to grasp quantitatively from which medicine bottle a drug solution is currently being suctioned. That is, the chemical solution preparation support system 10 can automatically determine which step of the preparation process of the chemical solution is currently. Therefore, the control unit 18 can display the information of the current step on the screen 17 a of the information presentation unit 17. Therefore, even when the work interruption occurs, the worker can easily resume the preparation operation of the drug solution by confirming the screen 17a. That is, dispensing errors due to work interruption can be effectively prevented.

Subsequently, a drug solution preparation support method using the drug solution preparation support system 10 described above will be described. FIG. 7 shows a flowchart of a drug solution preparation support method according to this embodiment.

As shown in FIG. 7, in the drug solution preparation support method according to this embodiment, the step S1 for reading a prescription ID, the first display step S2, the step S3 for collecting medicine bottles, and the step S4 for sucking a drug solution , And step S5 of injecting a drug solution and second display step S6.

In step S1, the reading unit 24 reads the prescription ID printed on the prescription 25, the control unit 18 transmits the prescription ID to the medical information database 12, and the medical information database 12 receives the patient information according to the received prescription ID. The control unit 18 causes the storage unit 19 to store the received information on the patient, the information on the medical solution, and the like.

In step S2, the control unit 18 reads out data such as the type of the drug solution, the dose of the drug solution, and the photographed image of the medicine bottle included in the information on the drug solution from the storage unit 19 and displays it on the screen 17a of the information presentation unit 17. .

In step S3, a worker such as a nurse or a pharmacist stocks the medicine bottle 20 containing the drug solution to be injected into the infusion bag 21 on the medicine bottle placement unit 14a. At this time, the vial weight measurement unit 14 measures the total weight of all the vials placed on the vial placement unit 14a (a vial weight measurement step). Then, the control unit 18 generates audit information representing the inspection result of the medicine bottle sorting operation based on the change in weight measured by the medicine bottle weight measurement unit 14, and stores the generated audit information in the storage unit 19. Store (first audit information generation step).

In step S4, the worker picks up the medicine bottle 20 from the medicine bottle placement unit 14a. Then, the operator operates the syringe drive device 23 to suck the drug solution from the taken drug bottle 20 into the syringe 23a mounted on the syringe drive device 23, and the drug bottle 20 after the drug solution suction is drug bottle It returns on the mounting part 14a. At this time, the vial weight measurement unit 14 measures the total weight of all the vials placed on the vial placement unit 14a (a vial weight measurement step). Then, the control unit 18 generates, based on the change in weight measured by the medicine bottle weight measurement unit 14, audit information representing an inspection result of the picking operation of the medicine bottle and the suction operation of the drug solution, and the generated audit information Are stored in the storage unit 19 (first audit information generation step).

Specifically, in step S4, the medicine bottles are taken in a predetermined mixing and preparation order based on the change in weight measured by the medicine bottle weight measurement unit 14 due to the medicine bottle 20 being picked up from the drug solution placement unit 14a. It will be audited whether it is taken up without a doubt. In addition, a predetermined dose from the medicine bottle 20 picked up based on a change in weight measured by the medicine bottle weight measurement unit 14 due to the medicine bottle 20 after the liquid medicine suctioning being returned to the medicine bottle placement unit 14a. It is audited whether or not the drug solution is definitely aspirated.

In step S5, the operator operates the syringe drive device 23 to inject a drug solution from the syringe 23a into the infusion bag 21. At this time, the infusion bag weight measurement unit 15 measures the weight of the infusion bag 21 placed on the infusion bag placement unit 15a (infusion bag weight measurement step). Then, based on the change in weight measured by the infusion bag weight measurement unit 15, the control unit 18 generates audit information representing the audit result of the liquid injection operation, and stores the generated audit information in the storage unit 19. (2nd audit information generation step).

In step S6, the control unit 18 reads out the audit information from the storage unit 19 and causes the screen 17a of the information presentation unit 17 to display it.

The medical fluid preparation support device 11 may be provided with an input unit that can input a prescription ID instead of the reading unit 24 so that the input prescription ID may be transmitted to the medical information database 12 in step S1.

Based on the changes in weight measured by the vial weight measurement unit 14 and the infusion bag weight measurement unit 15 according to the method described above, counting audits of the vials and comparison audits of types of medicine bottles (types of chemical solutions) Can audit the mixing and preparation order of the drug solution, measure audit of the drug solution, etc., and by these audits, errors in the selection of the drug vials, mistaking of the drug vial when preparing the drug solution, and the amount of drug solution Errors and the like can be prevented. Therefore, safe and accurate preparation of the drug solution can be achieved.

Then, the specific example of the chemical | medical solution preparation assistance method which concerns on this embodiment is demonstrated. FIG. 8 shows the first half of a flowchart of a specific example of the chemical solution preparation support method according to this embodiment, and FIG. 9 shows the second half of the flowchart. FIGS. 10 to 22 show an example of an image displayed on the screen 17 a of the information presentation unit 17 along the flowcharts shown in FIGS. 8 and 9. As described above, the image displayed on the screen 17 a of the information presentation unit 17 is controlled by the control unit 18. In the example shown in FIG. 8 and FIG. 9, the case where all the medical fluid to be injected into the infusion bag 21 is injected into the infusion bag 21 at one time will be described. Also in the examples shown in FIG. 8 and FIG. 9, the cases where the medicines A, B and C need to be injected into the infusion bag 21 and the medicines A, B and C are mixed and prepared in this order will be described. .

First, in step S10, as shown in FIG. 10, an image instructing the worker to insert the prescription 25 into the reading unit 24 is displayed on the screen 17a of the information presenting unit 17.

When a worker such as a nurse or a pharmacist inserts the prescription 25 into the reading unit 24 according to the instruction displayed on the screen 17a, the reading unit 24 reads the prescription ID printed on the prescription 25 (step S11). Move to step S12.

In step S12, the control unit 18 transmits the prescription ID read by the reading unit 24 to the medical information database 12. The medical information database 12 transmits information on a drug solution according to the received prescription ID, patient information, and the like. The control unit 18 causes the storage unit 19 to store the information transmitted from the medical information database 12. During this time, as shown in FIG. 11, an image is displayed on the screen 17a of the information presentation unit 17 indicating that information on a drug solution, information on a patient, and the like are currently being acquired from the medical information database 12. When the information on the drug solution, the information on the patient, and the like are stored in the storage unit 19, the process moves to step S13.

In step S13, the medicine bottle 20 is placed on the medicine bottle placement unit 14a on the screen 17a of the information presentation unit 17 as shown in FIG. 12 based on the information on the drug solution and the patient information stored in the storage unit 19. An image is displayed that instructs the operator to place the infusion bag 21 on the infusion bag placement unit 15a.

In this embodiment, the case where a chemical solution A is mixed with 1 V (1 vial), a chemical solution B with 1 A (1 ampule), and a chemical solution C with 1 V (1 vial) will be described. In the drug solution information display 17f, the names and doses of the drug solutions A, B, and C are displayed side by side from the left in the mixing preparation order together with the photographed images 20c of the respective medicine bottles containing the drug solutions A, B, and C.

The operator places the medicine bottle 20 on the medicine bottle placement unit 14a and places the infusion bag 21 on the infusion bag placement unit 15a according to the instruction displayed on the screen 17a.

At this time, as described above, whether or not there is an error in the type of medicine bottles (medicinal solution) or the arrangement order of medicine bottles based on the change in weight measured by the medicine bottle weight measurement unit 14 It is determined. Note that, as described above, when an error state is recognized from a comparison audit of the type of medicine bottle (chemical solution), an image indicating the occurrence of an error state may be displayed on the screen 17a (error information generation step) ). Alternatively, a buzzer sound (alarm sound) or the like may be sounded to notify occurrence of an error state.

At this time, as described above, the control unit 18 counts the number of changes in weight measured by the medicine bottle weight measurement unit 14, and based on the counting result, the number of collected medicine bottles 20 is calculated. It may be measured.

Furthermore, the control unit 18 recognizes the weight measured by the infusion bag weight measurement unit 15 when the infusion bag 21 is placed on the infusion bag placement unit 15a as the initial weight of the infusion bag 21, and stores the storage unit. Remember to 19.

The operator arranges the entire medicine bottle 20 on the medicine bottle placement unit 14a, places the infusion solution bag 21 on the infusion solution bag placement unit 15a, and then operates the completion button 17d on the screen 17a (step S14). Thereby, it moves to step S15.

In addition, the control unit 18 automatically recognizes that the entire medicine bottle 20 is placed on the medicine bottle placement unit 14a and the infusion bag 21 is placed on the infusion bag placement unit 15a. You may move to S15. The completion of the assortment of medicine bottles 20 can be determined, for example, from the result of the matching audit of the kind of medicine bottles 20 (kind of liquid medicine) prepared. Also, for example, does the completion of the assortment of vials 20 coincide with the data of the total value of the initial weights of all the vials previously stored in the storage unit 19 as measured by the vial weight measuring unit 14? It can be determined by whether or not. Here, to match means to match within an error range. When the data of the total value of the initial weight of all vials is included in the information on the liquid medicine, the included data may be used. Alternatively, the control unit 18 calculates the total value of the initial weights of all vials using the data of the initial weights of all vials included in the information on the drug solution, and stores the calculation result in the storage unit 19 It is also good.

In addition, before moving to step S15, the control unit 18 may perform count inspection of the prepared medicine bottles, as described above. Further, as described above, when the error state is recognized from the counting audit of the medicine bottle (medical solution), an image indicating the occurrence of the error state may be displayed on the screen 17a (error information generation step). Alternatively, a buzzer sound (alarm sound) or the like may be sounded to notify occurrence of an error state.

In step S15, as shown in FIG. 13, the syringe drive unit 23 is taken out from the cradle unit 16 on the screen 17a of the information presentation unit 17, and the syringe drive unit 23 taken out is attached to the syringe drive unit 23. An image is displayed that instructs the operator to attach the injection needle 23b to the syringe 23a attached to the.

The operator takes out the syringe drive device 23 from the cradle unit 16 according to the instruction displayed on the screen 17 a, mounts the syringe 23 a on the taken-out syringe drive device 23, and on the syringe 23 a attached to the syringe drive device 23. After the injection needle 23 b is attached, the syringe drive device 23 is returned to the cradle unit 16.

At this time, the control unit 18 recognizes the weight measured by the cradle unit 16 when the syringe drive unit 23 is returned to the cradle unit 16 as the initial weight of the syringe drive unit 23 and stores the weight in the storage unit 19. .

After returning the syringe drive device 23 to the cradle unit 16, the operator operates the completion button 17d on the screen 17a. Thereby, it moves to step S16. The control unit 18 may move to step S16 by automatically recognizing that the syringe drive device 23 has been returned to the cradle unit 16. Whether or not the syringe drive device 23 is returned can be determined, for example, based on whether or not the weight measured by the cradle unit 16 has changed from zero.

In step S16, as shown in FIG. 14, on the screen 17a of the information presentation unit 17, based on the information on the chemical solution stored in the storage unit 19, an image for instructing the operator of the medicine bottle to be aspirated is displayed. FIG. 14 illustrates the case where the medicine bottle to be sucked is the medicine bottle A. In this embodiment, in the drug solution information display 17f on which the shot image 20c of the drug bottle is displayed, the shot image 20c of the drug bottle to be sucked and the name and the dose of the drug solution contained in the drug bottle to be sucked are Zoom in. By doing this, the operator can visually confirm the medicine bottle to be picked up, and it is possible to prevent the occurrence of a mistake in the medicine bottle.

Furthermore, when information on precautions when suctioning a chemical solution, such as the driving speed of the syringe drive device 23, is included in the information on the chemical solution, in step S16, the caution item 17g included in the information on the chemical solution is displayed on the screen 17a. Be done. By presenting a warning to the operator in this manner, safer and more accurate preparation of the drug solution can be achieved. FIG. 14 shows, as an example, a caution item 17 g indicating that the syringe drive device 23 needs to be operated in the low speed mode because the chemical solution A easily foams. When the operator operates the syringe drive device 23 according to this caution item 17 g, it is possible to prevent the foaming and efficiently suction the chemical solution.

Moreover, in this embodiment, in step S16, the light emission of the LED display unit corresponding to the medicine bottle 20 to be sucked is started. In the work instruction display 17c, an instruction to suction the chemical solution from the medicine bottle 20 corresponding to the position where the LED display unit emits light (the LED display position) is displayed. The light emission of the LED display unit continues until the taken medicine bottle 20 is returned onto the medicine bottle mounting portion 14a.

The operator picks up the medicine bottle 20 in accordance with the instructions displayed on the screen 17a. At this time, as described above, the control unit 18 measures the weight of the picked-up vial 20 based on the change in weight measured by the vial weight measuring unit 14. As a result, a comparison audit of the type of medicine bottle 20 (type of liquid medicine) taken up and an audit of the order of picking up the medicine bottle 20 are performed (step S16A). Further, at this time, as described above, the control unit 18 counts the number of changes in weight measured by the vial weight measuring unit 14, and based on the counting result, the medicine bottle loading unit 14 a The number of times 20 is picked up (the number of medicine bottles 20 picked up) may be measured.

After picking up the medicine bottle 20, the operator operates the completion button 17d on the screen 17a when not receiving a warning about occurrence of an error state from the liquid medicine preparation support system 10. Thereby, it moves to step S17. If the correct state is recognized from the result of the audit in step S16A, the process may automatically move to step S17. Alternatively, the control unit 18 may move to step S17 by automatically recognizing that the medicine bottle 20 has been picked up from the medicine bottle placement unit 14a. Whether or not the medicine bottle 20 has been picked up can be determined, for example, by whether or not the weight measured by the medicine bottle weight measurement unit 14 has decreased.

When the worker picks up the wrong medicine bottle 20, as described above, an image indicating the occurrence of an error state is displayed on the screen 17a (error information generation step). Alternatively, a buzzer sound (alarm sound) or the like notifying the occurrence of an error state is sounded.

When returning from the error state, that is, when the operator returns the misplaced medicine bottle 20 onto the medicine bottle mounting portion 14a, the process returns to step S16. Whether or not the error state is recovered can be automatically determined, for example, by whether or not the weight measured by the vial weight measurement unit 14 has increased.

In step S17, it is determined whether the picked up vial 20 is a vial container. This determination is made by the control unit 18 based on the information on the chemical solution stored in the storage unit 19. If the medicine bottle 20 is a vial container, the process moves to step S18. On the other hand, if the medicine bottle 20 is not a vial container, the process moves to step S19.

In step S18, an image is displayed on the screen 17a of the information presentation unit 17 based on the information on the chemical solution stored in the storage unit 19 to instruct the operator to use the empty amount of the syringe and the pumping suction of the chemical solution. FIG. 15 exemplifies a work instruction display 17c for displaying an instruction to pump and aspirate a medical solution after suctioning 10 ml of air to the syringe 23a. The information on the operation procedure of the syringe drive device 23 is included in the information on the drug solution.

When the medicine bottle 20 is a vial container, in order to keep the internal pressure of the vial container as constant as possible at the time of suction of the drug solution, the replacement air of an amount corresponding to the amount of drug solution to be sucked (dose of the drug solution) There is a need. Also, it is necessary to perform pumping suction. Therefore, when the medicine bottle 20 is a vial container, the operator operates the syringe drive device 23 according to the instruction displayed on the screen 17a by presenting the operation procedure of the syringe drive device 23 to the worker. The drug solution can be suctioned efficiently.

As described above, by presenting the information on the operation procedure of the syringe drive device 23 to the worker, it is possible to more efficiently suction the drug solution. Needless to say, the information on the operation procedure of the syringe drive device 23 is not limited to the instruction displayed on the work instruction display 17 c in FIG.

The operator sucks the drug solution from the taken medicine bottle 20, and then operates the completion button 17d on the screen 17a. Thereby, it moves to step S19.

The empty amount of the syringe is set to a slightly smaller amount than the dose of the drug solution. As a result, when the liquid medicine in the vial container is aspirated by a predetermined amount, the inside of the vial container can be always under negative pressure. Therefore, it is possible to prevent so-called aerosol phenomenon that residual liquid etc. are ejected from the inside of the vial container when the injection needle 23b is extracted from the vial container.

In step S19, as shown in FIG. 16, based on the information on the drug solution stored in the storage unit 19, an image for instructing the operator to return the medicine bottle is displayed on the screen 17a of the information presentation unit 17. FIG. 16 illustrates the case where the medicine bottle to be returned is the medicine bottle A. In this embodiment, the photographed image 20c or the like of the medicine bottle to be returned is enlarged and displayed. Moreover, in this embodiment, the LED display unit corresponding to the medicine bottle to be returned emits light, and the work instruction display 17c shows the medicine bottle at the position where the LED display unit emits light (the LED display position). An instruction to return is displayed. By so doing, the worker can more reliably return the medicine bottle 20 to the original position.

After aspirating the drug solution from the taken medicine bottle 20, the worker returns the medicine bottle 20 according to the instruction displayed on the screen 17a. At this time, as described above, the control unit 18 measures the weight of the aspirated drug solution or the amount of the aspirated drug solution based on the change in the weight measured by the vial weight measurement unit 14.
