  In the device described in Japanese Patent Application Laid-Open No. 2003-325639 (Patent Document 1), the liquid medicine bottle is held in an upright state so that the opening portion opens upward, and the tube passes through the opening portion and the liquid medicine is dispensed. It is inserted into the bottle and the drug solution is sucked through the tube. When the liquid medicine cannot be sucked automatically from the liquid medicine bottle, it is determined that the liquid medicine in the liquid medicine bottle has run out, and the liquid medicine bottle is replaced.

  Since the chemical solution is sucked using a tube inserted from above into the liquid medicine bottle, the liquid medicine may not be automatically sucked from the liquid medicine bottle even though the medicine remains at the bottom of the liquid medicine bottle. is there. If the liquid medicine bottle with the liquid medicine remaining is exchanged and discarded, the residual liquid medicine is discarded without being used, resulting in waste. In order to avoid this waste, it is necessary to transfer the liquid medicine remaining in the liquid medicine bottle after replacement to the container, measure an appropriate amount of liquid medicine, and inject it into the medication bottle. This operation has to be performed manually by the operator, and therefore has a problem that takes time.

When the detection unit detects the liquid medicine shortage state, the determination unit compares the remaining amount of liquid medicine remaining in the liquid medicine bottle with the unsupplied amount of liquid medicine that has not yet been supplied to the medication bottle. The determination unit further determines that the liquid medicine remaining in the liquid medicine bottle can be injected into the prescription bottle if the liquid medicine remaining amount is less than the unsupplied amount, and the liquid medicine remaining amount is not supplied. If it exceeds, it is judged that the liquid medicine remaining in the liquid medicine bottle cannot be injected into the medication bottle. The display unit displays the result of determination by the determination unit.

  In the liquid medicine supply apparatus, preferably, the tubular member is a supply pipe. The supply pipe forms a path through which the liquid medicine flows from the liquid medicine bottle to the medication bottle. The liquid medicine supply device further includes a transfer unit. The transfer unit transfers the liquid medicine from the liquid medicine bottle to the medication bottle via the supply pipe. The detection unit detects a state in which the liquid medicine is not supplied to the prescription bottle as a liquid medicine shortage state even if the transfer unit attempts to transfer the liquid medicine.

  Preferably, in the liquid medicine supply device, after the detection unit detects the liquid medicine shortage state, an amount of liquid medicine obtained by subtracting the injection amount of the liquid medicine injected into the prescription bottle from the unsupplied amount is supplied to the prescription bottle.

  Preferably, the liquid medicine supply device includes a storage unit that stores a medicine name and a remaining amount of the liquid medicine remaining in the liquid medicine bottle when the determination part determines that the injection into the prescription bottle is impossible. .

The elevating device 50 causes the medication bottle 2 to reciprocate between the outside and the inside of the casing 6 of the liquid medicine supply device 1 so as to reciprocate between the attachment / detachment position and the dispensing position.

  FIG. 6 is a schematic diagram showing the overall configuration of the supply pipe 60. The supply pipe 60 forms a path through which the liquid medicine 5 flows from the liquid medicine bottle 23 toward the medication bottle 2. The liquid medicine supply apparatus 1 includes a plurality of supply pipes 60 so that different liquid medicines 5 can be supplied from each of the plurality of liquid medicine bottles 23 to the medication bottle 2.

  The supply pipe 60 includes the supply nozzle 36 and the tube 34 described above. The tube 34 has a suction end 34a that is one end and a discharge end 34b that is the other end. The suction end 34 a opened by the tube 34 is arranged inside the liquid medicine bottle 23 and is immersed in the liquid medicine 5 in the liquid medicine bottle 23. The suction end 34 a is an end portion on the side where the liquid medicine 5 is sucked into the tube 34 when the liquid medicine 5 is supplied from the liquid medicine bottle 23 to the prescription bottle 2. The discharge end 34 b is an end portion on the side of discharging the liquid medicine 5 from the tube 34 when supplying the liquid medicine 5 from the liquid medicine bottle 23 to the prescription bottle 2. The discharge end 34 b of the tube 34 is attached to the supply nozzle 36.

  The supply port 36 </ b> A having an open end of the supply nozzle 36 forms one end of the supply pipe 60 on the prescription bottle 2 side. One end of the supply pipe 60 is arranged to face the upper opening 2 </ b> A of the prescription bottle 2. When the liquid medicine 5 in the liquid medicine bottle 23 is supplied to the prescription bottle 2, the supply port 36 </ b> A of the supply nozzle 36 is arranged to face the upper opening 2 </ b> A of the prescription bottle 2. The liquid medication 5 flows out from the supply pipe 60 toward the prescription bottle 2 via one end of the supply pipe 60. The suction end 34a of the tube 34 forms the other end of the supply pipe 60 on the liquid medicine bottle 23 side. The other end of the supply pipe 60 is inserted into the liquid medicine bottle 23 and submerged in the liquid medicine 5 accommodated in the liquid medicine bottle 23.

  The pump 24 is used as a power source for sucking the liquid medicine 5 in the liquid medicine bottle 23 toward the supply nozzle 36. When the pump 24 is a tube pump, an intermediate portion of the tube 34 between the suction end 34 a and the discharge end 34 b is inserted into the pump 24 and is detachably gripped by the pump 24.

  By driving the pump 24, the liquid medicine 5 in the liquid medicine bottle 23 is sucked into the supply pipe 60 from the suction end 34a, flows through the inside of the supply pipe 60, and passes through the supply port 36A of the supply nozzle 36. It flows out from the supply pipe 60. The liquid medicine 5 flowing out from the supply pipe 60 flows into the medication bottle 2 via the upper opening 2 </ b> A of the medication bottle 2. Thus, the liquid medicine 5 is transferred from each of the plurality of liquid medicine bottles 23 to the prescription bottle 2 via the supply pipe 60, and the liquid medicine 5 is supplied to the prescription bottle 2. By selecting a combination of the liquid medicine bottle 23 and the supply pipe 60, different types of liquid medicine 5 or excipients are selectively supplied to the medication bottle 2.

  In addition, as a transfer part which transfers the liquid medicine 5 to the prescription bottle 2 via the supply pipe | tube 60 from the liquid medicine bottle 23, you may use arbitrary pumps 24, such as a syringe pump other than the tube pump mentioned above. . Further, the transfer unit is not limited to the pump 24. For example, the supply port 36A is installed below the liquid surface of the liquid medicine 5 in the liquid medicine bottle 23, and the medicine is dispensed from the liquid medicine bottle 23 using gravity. The liquid medicine 5 may be transferred to the bottle 2.

  The liquid medicine supply device 1 is an apparatus for supplying the liquid medicine 5 from the liquid medicine bottle 23 to the prescription bottle 2 through the tubular member, and the liquid medicine 5 flows from the liquid medicine bottle 23 toward the prescription bottle 5. It should be understood that the supply pipe 60 forming the passage is illustrated as an example of this “tubular member”. As a tubular member of another example, for example, it moves between the inside of the liquid medicine bottle 23 and the upper part of the prescription bottle 2, sucks the liquid medicine 5 in the liquid medicine bottle 23 and sucks it above the prescription bottle 2. It is possible to envisage a pipette tip that discharges the prepared liquid.

  FIG. 7 is a block diagram showing the configuration of the liquid medicine supply device 1. As shown in FIG. 7, the liquid medicine supply device 1 includes a control unit 90 that controls the operation of the liquid medicine supply device 1 as a whole. The touch panel 14 functions as an input unit for inputting various parameters related to the operation of the liquid medicine supply device 1 such as prescription data, and various information such as a patient name and a pharmacist name. The touch panel 14 also functions as a display unit that displays the operation state of the liquid medicine supply device 1. In addition to the touch panel 14, the liquid supply device 1 may include, for example, a lamp that is turned on when a malfunction of the liquid supply device 1 occurs as a display unit.

  The electronic balance 45 detects the weight of the liquid medicine 5 supplied to the prescription bottle 2 and inputs the detected weight value to the control unit 90. The control unit 90 supplies a predetermined amount of the liquid medicine 5 to the prescription bottle 2 while receiving the weight data of the liquid medicine 5 in the prescription bottle 2 from the electronic balance 45.

  The liquid medicine supply device 1 includes bottle position detection means 91 that detects the position of each liquid medicine bottle 23 in the lower space 12 inside the housing 6. The bottle position detection means 91 may be, for example, various sensors, and the sensor may detect a rotation angle of the liquid medicine bottle holder 32 around the drum axis. As the rotary drum 21 rotates, the liquid medicine bottle 23 rotates around the drum axis, so that the current position of the liquid medicine bottle 23 changes frequently. The current position of the liquid medicine bottle 23 is accurately detected using the bottle position detecting means 91, and data relating to the detected current position of the liquid medicine bottle 23 is input to the control unit 90.

  The liquid medicine supply device 1 also includes a communication unit 92 for communicating with an external device and receiving data from the external device. Various parameters related to the operation of the liquid medicine supply device 1 may be input to the control unit 90 by the operation of the touch panel 14 described above, or alternatively, the control unit 90 from an external computer via the communication unit 92. May be entered.

  The liquid medicine supply device 1 also includes a memory 93 for the control unit 90 to perform calculations. The memory 93 is data indicating the supply necessary amount of the liquid medicine 5 to be supplied to the prescription bottle 2 according to the prescription, data indicating the supply amount of the liquid medicine 5 already supplied to the prescription bottle 2 at the present time, and the pump Data indicating the remaining amount of liquid medicine 5 remaining in liquid medicine bottle 23 when liquid medicine 5 cannot be dispensed from liquid medicine bottle 23 by driving 24 is stored. The memory 93 may store data on the liquid medicine 5 contained in the liquid medicine bottle 23 mounted on the liquid medicine supply apparatus 1 and data relating to the current position of the liquid medicine bottle 23. The memory 93 has a function as a storage unit that stores various data relating to the operation of the liquid medicine supply device 1.

  The liquid medicine supply device 1 also includes a recording medium access unit 94 for mounting a removable recording medium. The data of the liquid medicine 5 described above may be stored in various recording media attached to the recording medium access unit 94 and appropriately read from the recording medium by the control unit 90.

  The control unit 90 controls the liquid medicine supply device 1 based on information input from the various devices described above. Specifically, control signals are transmitted from the control unit 90 to the drum rotating motor 22, the moving motor 39, the pump driving motor 40, the agitating motor 62 of the liquid medication 5, and the lifting device 50, and each motor is transmitted. Is appropriately operated and stopped, so that the liquid medicine 5 is supplied from the liquid medicine bottle 23 to the prescription bottle 2. After the supply of the liquid medication 5 is completed, a piece of paper on which the extraction result is printed, and a medication bottle 2 on which a patient name, a pharmacy name, a medication time, a medication amount, and the like are printed are attached from the printers 17a and 17b constituting the output unit 17. The label for is output.

  FIG. 8 is an example of a table showing the setting of the supply amount of the liquid medicine 5 to the medication bottle 2. The required supply amount shown in FIG. 8 indicates the amount of liquid 5 that should be supplied to the medication bottle 2 based on the prescription data. The amount of the liquid 5 already supplied to the prescription bottle 2 at a certain point in the middle of the supply of the liquid 5 to the prescription bottle 2 is the current supply amount shown in FIG. The amount of the liquid medicine 5 that has not yet been supplied is the unsupplied amount shown in FIG. A relationship of Q0−Q1 = Q2 is established among the supply required amount Q0, the supply amount Q1 up to now, and the unsupply amount Q2.

  The supply amount Q1 up to now is calculated from the weight and density of the liquid medicine 5 based on the weight data of the liquid medicine 5 in the prescription bottle 2 detected by the weight detection unit 4. As the liquid medication 5 is supplied to the medication bottle 2, the weight of the liquid medication 5 in the medication bottle 2 increases. Each time the controller 90 sequentially receives the weight data of the liquid medicine 5 from the electronic balance 45, the control unit 90 updates the supply amount Q1 and the unsupply amount Q2 up to now based on the weight data and stores them in the memory 93. .

  The remaining amount shown in FIG. 8 is during the supply of the liquid medicine 5 from the liquid medicine bottle 23 to the prescription bottle 2 using the liquid medicine supply apparatus 1, that is, before the supply of the liquid medicine 5 to the prescription bottle 2 is completed. The pump 24 indicates the amount of the liquid medicine 5 remaining in the liquid medicine bottle 23 when the liquid medicine 5 cannot be supplied to the prescription bottle 2 while being operated.

  The value of the remaining amount R may be set in advance. For example, the maximum amount of the liquid medicine 5 that can remain in the liquid medicine bottle 23 may be experimentally obtained in advance, and the obtained value may be input to the liquid medicine supply apparatus 1 to set the remaining amount R. In this case, the remaining amount R may be set to about 5 ml, for example. A different amount of remaining amount R may be set for each liquid medicine bottle 23. Alternatively, a common remaining amount R may be set for all liquid medicine bottles 23. When the common remaining amount R is determined, the maximum value among the remaining amounts of liquid medicines different for each liquid medicine bottle 23 may be set as the remaining amount R, and a value obtained by adding a margin value to the maximum value remains. The amount R may be set.

  In another example, the remaining amount R may be set according to the outer diameter of the liquid medicine bottle 23. Depending on the type of liquid 5 or excipient, the shape of liquid bottle 23 is different. The cross-sectional area of the liquid medicine bottle 23 is proportional to the square of the outer diameter of the liquid medicine bottle 23, and it is considered that the remaining amount R increases as the outer diameter of the liquid medicine bottle 23 increases. Therefore, regarding the remaining amount R and the outer diameter of the liquid medicine bottle 23, for example, a relational expression is set assuming that the remaining amount R is proportional to the square of the outer diameter of the liquid medicine bottle 23, and the outer diameter of the liquid medicine bottle 23 is set as the touch panel 14. The remaining amount R may be calculated in the control unit 90 based on the outer diameter and the relational expression, for example, by inputting the value via the key or by storing it in the memory 93 in advance.

  In another example, the remaining amount R may be set according to a detection value obtained by detecting the weight of the liquid medicine bottle 23. In this case, for example, a sensor that functions as a weight detection unit that sequentially detects the current weight of each liquid medicine bottle 23 is attached to the liquid medicine bottle holder 32 that holds the liquid medicine bottle 23, and the weight detection by the sensor is performed. The weight of the liquid medicine 5 in the liquid medicine bottle 23 may be calculated by subtracting the weight of the liquid medicine bottle 23 itself from the value. Alternatively, since the remaining amount R is required when replacing the liquid medicine bottle 23, the electronic balance 45 is used as a weight detection unit for detecting the weight of the liquid medicine bottle 23, and the electronic balance 45 is used for the remaining amount. The amount R may be detected. For example, the liquid medicine bottle 23 that has been removed from the liquid medicine supply apparatus 1 for replacement is placed on the electronic balance 45, the weight is detected, and the weight of the liquid medicine bottle 23 itself is subtracted, thereby remaining. The amount R may be calculated.

  In still another example, the value of the remaining amount R may be set by manually measuring the amount of the liquid 5 actually remaining in the liquid bottle 23. For example, the remaining liquid medicine 5 is poured out from the liquid medicine bottle 23 removed from the liquid medicine supply apparatus 1 for replacement of the liquid medicine bottle 23 to a measuring container, and the amount of the liquid medicine 5 in the container is measured. By doing so, the remaining amount R may be set. In this case, the amount of the liquid 5 in the container may be calculated by measuring the container after dispensing the liquid 5 with the weight detection unit 4 and obtaining data on the weight of the liquid 5.

  Using the liquid medicine supply device 1 described above, the liquid medicine 5 from the liquid medicine bottle 23 to the prescription bottle 2 based on the prescription data including the chemical name of the liquid medicine 5 and the supply amount Q0 of the liquid medicine 5 is used. Control in the case of dispensing by supplying FIG. 9 is a flowchart showing liquid medication supply processing to the medication bottle 2.

  First, when the touch panel 14 is operated to issue a command for starting the supply of the liquid medication 5 to the prescription bottle 2, prescription data including the medicine name and the necessary supply amount Q0 is called. After setting the prescription bottle 2 on the mounting table 48 in the initial position for setting the prescription bottle 2 on the mounting table 48, a control signal is transmitted to the lifting device 50 as shown in step (S11). When the lifting device 50 moves the weight detection unit 4 upward, the medication bottle 2 is raised. The weight detection unit 4 moves upward until it reaches a supply position where the liquid medication 5 is supplied to the prescription bottle 2.

  Next, in step (S12), the drum rotating motor 22 is controlled, and the rotating drum 21 rotates. In an initial state before dispensing by the liquid medicine supply device 1, the supply port 36 </ b> A formed at the lower end of the supply nozzle 36 is not located at the position facing the upper opening 2 </ b> A formed at the upper end of the prescription bottle 2, The prescription bottle 2 is located between the supply nozzles 36 adjacent to each other in the direction. When the drum rotation motor 22 is driven, the rotary drum 21 rotates so that the supply nozzle 36 moves in a horizontal direction to a position where the supply port 36A of the supply nozzle 36 faces the upper opening 2A of the prescription bottle 2.

  At this time, the liquid medicine bottle 23 placed on the liquid medicine bottle holding body 32 attached to the rotating drum 21 also moves in the horizontal direction. Then, the liquid medicine bottle 23 that contains the liquid medicine 5 contained in the prescription data and for which the liquid medicine 5 accommodated is to be dispensed is disposed on the forefront side of the liquid medicine supply device 1. By moving the liquid medicine bottle 23 in this way, the type of liquid medicine 5 to be dispensed can be visually confirmed from the front of the liquid medicine supply apparatus 1.

  When the rotation of the rotary drum 21 is completed, the pump driving motor 40 is moved forward in the next step (S13), and the connecting member 42 of the pump driving motor 40 is connected to the connected member 44 of the pump 24. Thus, the rotation of the pump driving motor 40 can be transmitted to the pump 24, that is, the pump 24 can be driven. Subsequently, driving of the pump driving motor 40 is started, and the pump 24 is started. By starting the pump 24, the liquid medicine 5 in the liquid medicine bottle 23 is sucked through the supply pipe 60 and supply of the liquid medicine 5 in the liquid medicine bottle 23 to the medication bottle 2 is started.

  Next, in step (S14), it is determined whether or not there is a change in the weight value of the medication bottle 2 detected by the weight detection unit 4. The weight of the medication bottle 2 is sequentially detected by the weight detection unit 4. As the liquid medication 5 continues to be discharged into the medication bottle 2 and the amount of the medication 5 in the medication bottle 2 increases, the weight of the medication bottle 2 increases. The change in the weight value of the medication bottle 2 indicates that the supply of the liquid 5 to the medication bottle 2 is continued and the amount of the liquid 5 in the medication bottle 2 is increasing. If the weight value of the prescription bottle 2 increases sequentially, it can be seen that the liquid medication 5 is normally supplied. On the other hand, the fact that there is no change in the weight value of the prescription bottle 2 indicates that the amount of the liquid 5 in the prescription bottle 2 has not changed and the liquid 5 has not been supplied to the prescription bottle 2.

  Although the pump drive motor 40 is rotating and the pump 24 continues to operate, the pump 24 attempts to transfer the liquid medicine 5 to the medication bottle 2, but the weight value of the medication bottle 2 is reached. If there is no change, it can be determined that the pump 24 is idle and the liquid medication 5 is not supplied to the medication bottle 2. In this case, the liquid medicine bottle 23 is almost empty, the liquid medicine 5 in the liquid medicine bottle 23 is not remaining, and the amount of the liquid medicine 5 in the liquid medicine bottle 23 is insufficient. 23, it can be determined that the liquid medicine 5 cannot be sucked.

  In this specification, as a result of the amount of the liquid medicine 5 in the liquid medicine bottle 23 being decreased, the amount of the liquid medicine 5 in the liquid medicine bottle 23 is insufficient to suck the liquid medicine 5 from the liquid medicine bottle 23. The state is referred to as a liquid agent shortage state. By monitoring the weight value of the prescription bottle 2 in step (S14) and detecting that the weight value that has been increased does not change, it can be determined that the liquid medicine has become insufficient. The weight detection unit 4 functions as a detection unit that detects the liquid medicine shortage state.

  The liquid medicine 5 remaining in the liquid medicine bottle 23 when the liquid medicine is insufficient is referred to as a remaining medicine in this specification. The liquid medicine 5 in the liquid medicine bottle 23 is sucked upward by the tube 34 and flows out of the liquid medicine bottle 23. Therefore, depending on the arrangement of the suction end 34a of the tube 34 in the liquid medicine bottle 23, the liquid medicine 5 remaining at the bottom of the liquid medicine bottle 23 cannot be sucked, and as a result, a residual medicine is generated. The amount of the remaining medicine remaining in the liquid medicine bottle 23 is the remaining amount R shown in FIG. In addition, it is possible to improve the uniformity of the value of the remaining amount R for each liquid medicine bottle 23 by appropriately positioning the tube 34 inserted through the liquid medicine bottle 23 with respect to each liquid medicine bottle 23. It is.

  If it is determined in step (S14) that there is no change in the weight value of the prescription bottle 2 and it is determined that the liquid medicine is in a deficient state, the process proceeds to step (S21) and the supply of the liquid medicine 5 is stopped. In step (S21), the rotation of the pump driving motor 40 is stopped and the pump 24 is stopped, whereby the supply of the liquid medication 5 to the medication bottle 2 is stopped. At this time, the liquid medicine 5 in the liquid medicine bottle 23 is almost disappeared by an arbitrary method such as displaying “Drug out of drug error” in a pop-up on the display screen of the touch panel 14 constituting the display unit. Notify workers that replacement is required.

  Next, in step (S22), the operator determines whether or not the liquid agent shortage state, that is, the replacement of the liquid medicine bottle 23 that has run out of medicine is performed. When it is determined that the replacement work is to be performed, the process proceeds to step (S23), and in order to remove the medicine bottle 23 that has run out of medicine located on the forefront side of the liquid medicine supply device 1, the medication bottle 2 is removed. Is lowered from the supply position to the initial position. Thereby, an operator can access the lower space 12 of the liquid medicine supply device 1 through the lower opening 15, and the liquid medicine bottle 23 can be exchanged. At this time, the front cover 18 is opened as necessary.

  Next, in step (S24), it is determined whether or not the liquid medicine bottle 23 has been replaced. Replacing the liquid medicine bottle 23 is performed by removing the liquid medicine bottle 23 out of the medicine located on the forefront side of the apparatus from the apparatus and installing a new liquid medicine bottle 23 in the apparatus. The determination in step (S24) is repeated until the replacement of the liquid medicine bottle 23 is completed.

  When the replacement operation is completed, the process proceeds to step (S31), and the liquid medicine 5 (that is, the remaining medicine) that remains slightly in the medicine bottle 23 that has been removed from the liquid medicine supply device 1 is replaced with the liquid medicine 5 to the medication bottle 2. Judge whether to use for supply. As described above, since the liquid medicine supply device 1 cannot automatically supply the remaining medicine to the medication bottle 2, when using the remaining medicine, an operator needs to manually inject the remaining medicine into the medication bottle 2. . That is, in step (S31), it is determined whether the operator manually injects the remaining medicine from the liquid medicine bottle 23 into the medication bottle 2.

  If it is determined in step (S31) that the remaining medicine is to be injected into the medication bottle 2, the process proceeds to step (S32), and the medicine bottle 23 containing the remaining medicine to be injected, that is, the medicine that has been removed from the liquid medicine supply device 1 The barcode attached to the liquid medicine bottle 23 is read, and the chemical name of the liquid medicine 5 is acquired. Subsequently, in step (S33), by matching the acquired medicine name with the medicine name of the liquid medicine 5 that has run out of medicine, it is manually injected into the prescription bottle 2 with the liquid medicine 5 currently prescribed. Check if the remaining medicine is the same medicine. If it is determined that the medicine names do not match, the process proceeds to step (S38), a warning is displayed on the display screen of the touch panel 14, and then the process returns to the determination in step (S31).

  If it is determined in step (S33) that the medicine names match, the process proceeds to step (S34), and the remaining amount R of the liquid medicine 5 remaining in the liquid medicine bottle 23 and the unfilled bottle 2 are not yet supplied. Comparison with the supply amount Q2 is performed. The control unit 90 serving as a determination unit refers to the table shown in FIG. 8 stored in the memory 93, reads the data of the unsupplied amount Q2 and the data of the remaining amount R, and the value of the remaining amount R is the unsupplied amount. It is determined whether the value is equal to or less than the value of Q2. This determination is made so that when all of the liquid medicine 5 remaining in the liquid medicine bottle 23 is supplied to the prescription bottle 2, the amount of the liquid medicine 5 supplied to the prescription bottle 2 does not exceed the supply required amount Q0. This is performed because the remaining medicine in the medicine bottle 23 needs to be injected into the medication bottle 2.

  As a result of the determination, if the remaining amount R is equal to or less than the unsupplied amount Q2, the control unit 90 determines that the remaining medicine can be injected into the medication bottle 2, and proceeds to step (S35) where the remaining medicine is charged. The fact that it is OK is displayed on the display screen of the touch panel 14. The touch panel 14 displays the result of the determination as to whether or not the remaining medicine can be introduced by the control unit 90. Upon receiving this display, the operator grasps that it is determined that the remaining medicine can be injected, removes the medication bottle 2 from the medication bottle holder 47, and injects all the remaining medicine into the medication bottle 2. Subsequently, in step (S37), it is determined whether or not the remaining medicine has been injected into the medication bottle 2. Until the injection of the remaining medicine is completed, the determination in step (S37) is repeated.

  Thus, since the liquid medicine bottle 23 can be completely emptied by injecting the remaining medicine into the medication bottle 2, waste due to the occurrence of the remaining medicine can be prevented. Since the remaining amount R of the remaining medicine is equal to or less than the unsupplied amount Q2, even if all of the remaining medicine is injected into the medication bottle 2, the amount of the liquid medicine 5 in the medication bottle 2 after the injection is equal to the supply required amount Q0. It will not be exceeded. For this reason, all the remaining medicine can be injected into the medication bottle 2 without the need to accurately measure the amount of the remaining medicine, so that it is possible to reduce the trouble of manually measuring the amount of the remaining medicine.

  Thereafter, if the supply of the liquid 5 to the prescription bottle 2 using the liquid supply device 1 is automatically resumed, the liquid 5 in the supply required amount Q0 can be accurately supplied to the prescription bottle 2. When the prescription bottle 2 is held again by the prescription bottle holder 47 for automatic resumption of supply, the weight of the prescription bottle 2 is measured by the weight detection unit 4. By comparing the weight of the prescription bottle 2 before and after the manual injection, the amount of the remaining medicine actually injected into the prescription bottle 2 by the manual operation can be grasped. According to the weight data of the prescription bottle 2 after the injection, the supply amount Q1 up to now shown in FIG. 8 is updated, and the unsupply amount Q2 is also updated. That is, the amount obtained by subtracting the amount of the remaining medicine manually injected into the prescription bottle 2 from the unsupplied amount Q2 before injecting the remaining medicine manually is set as a new unsupplied amount Q2, and the liquid medicine supply device 1 is determined as a set value of the amount of liquid 5 to be supplied to the prescription bottle 2 after resumption of supply.

  On the other hand, as a result of the determination in step (S34), if the remaining amount R exceeds the unsupplied amount Q2, the control unit 90 determines that the remaining medicine cannot be injected into the medication bottle 2, and step (S36). ) To display on the display screen of the touch panel 14 that the remaining medicine is NG. The touch panel 14 displays the result of the determination as to whether or not the remaining medicine can be introduced by the control unit 90.

  When the remaining medicine injection becomes NG, the operator manually measures the unsupplied amount Q2 of the solution 5 from the medicine bottle 23, and then manually supplies the unsupplied amount Q2 of the solution. 5 may be injected into the medication bottle 2.

  When the remaining medicine injection becomes NG, the control unit 90 removes the medicine bottle 23 that has run out of medicine from the liquid medicine supply device 1 and the amount of the remaining medicine in the liquid medicine bottle 23. The date and time can be stored in the memory 93. The remaining amount R shown in FIG. 8 may be stored as the amount of remaining medicine, or the amount of the remaining medicine may be stored after measuring the weight of the liquid medicine bottle 23 and detecting a more accurate amount. Good. At this time, the printers 17a and 17b indicate that the liquid medicine 5 remains as a residual medicine, the name of the liquid medicine 5 left as the residual medicine, the amount of the residual medicine in the liquid medicine bottle 23, A label indicating the date and time when the medicine bottle 23 out of the medicine is removed from the medicine supply device 1 is printed, and the label is attached to the medicine bottle 23 to manage the medicine bottle 23 containing the remaining medicine. May be. Alternatively, the remaining medicine stored in the liquid medicine bottle 23 may be transferred to another container, and a printed label may be attached to the other container containing the remaining medicine.

  Further, when the liquid medicine bottle 23 is mounted on the liquid medicine supply device 1, the date and time when the liquid medicine bottle 23 is mounted (in other words, the date and time when the liquid medicine bottle 23 is opened) is stored in the memory 93. When the injection is NG, the date and time of loading may be displayed on the printed label. Thereby, even if the medicine bottle 23 which has run out of medicine is removed from the medicine supply device 1, the elapsed time since the liquid medicine bottle 23 is opened can be grasped, so that the use of medicine exceeding the expiration date is used. Can be prevented. By displaying the date and time when the liquid medicine bottle 23 is mounted on the liquid medicine supply apparatus 1 and the date and time when the liquid medicine bottle 23 is removed from the liquid medicine supply apparatus 1 on the printed label, the liquid medicine bottle 23 is opened until the medicine runs out. It becomes possible to grasp the period and the loading / unloading date / time of the liquid medicine supply device 1, and this can be used for chemical management.

  If the same drug is included in the subsequent formulation, this remaining drug can be injected into the medication bottle 2. The remaining medicine may be injected into the prescription bottle 2 before the start of the injection of the liquid medicine 5 into the prescription bottle 2 using the liquid medicine supply device 1 or when the medicine runs out in the subsequent prescription. Similarly to (S34), it may be determined whether the remaining medicine can be injected into the medication bottle 2.

  After it is determined in step (S37) that the injection of the remaining medicine has been completed, or after displaying on the display screen that the remaining medicine cannot be charged in step (S36), the process proceeds to step (S25), and the medication bottle 2 is It rises again from the initial position to the supply position. If it is determined in step (S31) that no remaining medicine is to be injected into the prescription bottle 2, the process immediately proceeds to step (S25), and the prescription bottle 2 is raised. Thereafter, in step (S <b> 26), the process of supplying the liquid medicine 5 to the prescription bottle 2 is resumed using the liquid medicine 5 in the new liquid medicine bottle 23. The amount of the liquid medication 5 that is automatically injected into the medication bottle 2 after the restart is the unsupplied amount Q2 shown in FIG.

  After the supply restarts, the process proceeds to step (S15), and it is determined whether or not the supply amount of the liquid medicine 5 to the prescription bottle 2 has reached the supply required amount Q0. That is, it is determined whether the supply amount Q1 up to now is equal to the supply requirement amount Q0. If it is determined in step (S14) that the weight value of the prescription bottle 2 continues to change and the supply of the liquid medicine 5 to the prescription bottle 2 is proceeding, the process proceeds to step (S15). Then, a determination is made to compare the supply amount Q1 up to now with the required supply amount Q0.

  If it is determined that the supply amount Q1 up to the present time is less than the required supply amount Q0, the process returns to the determination in step (S14). The pump drive motor 40 rotates and the supply of the liquid medication 5 is continued until the liquid supply 5 of the supply required amount Q0 specified in the prescription is supplied to the prescription bottle 2. If it is determined that the supply amount of the liquid medicine 5 to the prescription bottle 2 has reached the required supply amount Q0, the process proceeds to step (S16), the pump 24 is stopped, and the supply of the liquid medicine 5 to the prescription bottle 2 is stopped. Is done.

  Next, in step (S17), it is determined whether or not all of the liquid medication 5 (and excipient if necessary) included in the prescription is completely supplied to the medication bottle 2 and dispensing is complete. Is done. When the supply of the liquid medicine 5 is not completed, the process returns to the step (S12), and the rotary drum 21 is arranged so that the liquid medicine bottle 23 containing the liquid medicine 5 to be supplied next is arranged on the front side of the apparatus. It is rotated.

  When the supply of the liquid medication 5 is completed, the process proceeds to step (S18), and the lifting device 50 moves the mounting table 48 downward, so that the medication bottle 2 is lowered. The mounting table 48 moves downward until it returns from the supply position to the initial position. If it is determined in step (S22) that the medicine bottle 23 that has run out of medicine is not replaced, the supply of the liquid 5 to the prescription bottle 2 is stopped, and the process immediately proceeds to step (S18). Move 2 down. In this way, the dispensing using the liquid medicine supply device 1 of the present embodiment is completed.

  In the description so far, it has been determined that the liquid medicine has become deficient by detecting that the change in the weight of the medication bottle 2 has been eliminated, but the present invention is not limited to this configuration. As long as the liquid medicine shortage state where the liquid medicine 5 in the liquid medicine bottle 23 is insufficient can be detected, a detection unit having an arbitrary configuration may be used.

  For example, a sensor for monitoring the supply port 36A of the supply nozzle 36 is provided, and even when the pump 24 is in operation, the sensor detects that the liquid agent 5 is not discharged from the supply port 36A. It can be judged that it became. This sensor may be a non-contact type sensor having a transmitter that transmits a signal and a receiver that receives the signal.

  Further, for example, the weight of each liquid medicine bottle 23 may be sequentially detected by a sensor that detects the weight of each liquid medicine bottle 23 described above to detect the amount of liquid medicine 5 in the liquid medicine bottle 23. Alternatively, for each liquid medicine bottle 23, the cumulative value of the amount of liquid medicine 5 used in the past prescription is stored in the memory 93, and the cumulative use amount is subtracted from the accommodation amount of the liquid medicine bottle 23, whereby the liquid medicine bottle The amount of liquid medicine 5 in 23 may be detected. Alternatively, each liquid medicine bottle 23 is provided with a sensor that detects the liquid level of the liquid medicine 5 in the liquid medicine bottle 23, and the liquid level in the liquid medicine bottle 23 is sequentially detected by the sensor. An amount of 5 may be detected. Comparison between the remaining amount of the liquid medicine 5 in the liquid medicine bottle 23 detected by any of these methods and the remaining amount R which is a threshold value set in advance or according to the outer diameter of the liquid medicine bottle 23 Thus, it may be determined that the liquid medicine is in a shortage state.

  Although the embodiment of the present invention has been described as above, the embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
