Is formed. The center hole of each cylindrical portion 34b is closed by a closing plate 40 provided so as to be rotatable about the shaft portion 40a. The closing plate 40 includes a lid portion 40b that covers the center hole and a pressure receiving portion 40c that extends on the opposite side across the shaft portion 40a. The closing plate 40 normally closes the center hole by its own weight (or the urging force of the coil spring provided on the shaft portion 40a) of the lid portion 40b, and intrusion of dust or the like into the medicine bottle 37 with the upper opening portion opened. To prevent. Further, the closing plate 40 is rotated to the open position by being pushed down by the rod 43 of the dispensing unit 4 described later. In addition, 3a is a fan for ventilation.

(1-4. Dispensing part 4)
As shown in FIG. 6, the dispensing unit 4 includes a nozzle 42 and a rod 43 supported by the support unit 41. A pump (not shown) is connected to the nozzle 42 via a tube (not shown) so that cleaning water can be sucked and discharged. Note that the movement of the nozzle 42 and the control of the discharge of the suction water of the cleaning water can be performed by a conventionally known method (for example, see Japanese Patent Application Laid-Open No. 2004-245715).

  As shown in FIGS. 2 and 6, the support portion 41 includes a first rail 44 that extends in the front-rear direction provided on the inner surfaces of both sides of the apparatus main body 1, and a first rail 44 that is movably provided in the front-rear direction along the first rail 44. The internal space can be moved in the X-axis, Y-axis, and Z-axis directions by the two rails 45 and the third rail 46 of the frame body 4a provided so as to be movable in the left-right direction along the second rail 45. Yes. That is, the support portion 41 moves up and down along the third rail 46, the third rail 46 moves left and right along the second rail 45, and the second rail 45 moves back and forth along the first rail 44. Moving.

  On the lower side of the support portion 41, a dripping prevention portion 47 having a concave portion 47a formed on the upper surface is provided. The liquid dripping prevention unit 47 is driven by a motor 47b, and a receiving position located below the nozzle 42 around a support shaft 47e provided on the side of the third rail 46 via a pulley 47c and a belt 47d. Each can turn to a retracted position located on the side. Further, a reader (not shown) for reading information written in the RFID built in the annular body 38 of the medicine bottle 37 is provided below the support portion 41.

  The nozzle 42 is connected to a cylinder (not shown), draws in the chemical solution from the drug bottle 37 by retreating the piston in the cylinder, and temporarily stores it. And the chemical | medical solution attracted | sucked by advancing a piston is discharged | emitted to the container 16 for patients. In the cylinder, it is preferable that a certain amount of air is sealed in advance so that the chemical liquid does not directly touch the piston when the chemical liquid is sucked.

  The rod 43 is disposed in front of the nozzle 42 and is supported so as to be movable up and down with respect to the support portion 41. The lower end position of the rod 43 is located below the lower end position of the nozzle 42. Thereby, first, the pressure receiving part 40c of the closing plate 40 of the chemical solution supply part 3 is pressed by the lower end part of the rod 43, and after the closing plate 40 is opened, the nozzle 42 passes through the center hole of the cylindrical part 34b. The bottle 37 can enter the inside from the upper opening. And if the support part 41 is moved to the downward side, the rod 43 will slide with respect to the support part 41, and the fall of the nozzle 42 is not inhibited. The rod 43 is also used to move the patient container 16 aligned with the container supply unit 2. In other words, the single rod 43 can be configured to perform two functions.

(1-5. Cleaning part)
As shown in FIG. 7, the cleaning unit 5 includes a cleaning container 48 and an air supply cylinder 49 disposed on the upper side. The cleaning container 48 includes an outer container 50 and an inner container 51. The inner container 51 is connected to the cleaning water supply tank 9 through a tube 51a, and cleaning water is appropriately supplied by driving a pump (not shown). The washing water overflowing from the inner container 51 is stored in an outer region between the outer container 50 and is recovered into the recovery tank 10 via a tube 50a connected to the side wall of the outer container 50. In the air supply tube 49, air is blown from the blower 42b to the nozzle 42 passing through the inside through an opening 42a formed in the side wall. Thereby, the water droplets adhering to the ridge and the outer peripheral surface remaining at the tip of the nozzle 42 can be dropped.

(2. Operation)
Next, the operation of the dispensing apparatus having the above configuration will be described.

  Prior to the start of dispensing, the container supply unit 2 aligns the patient containers 16 with the guide members 17 in each row according to size in the minor axis direction. And the press piece 19 is arrange | positioned at the back side. Thereby, the alignment state of the container 16 for patients in each row | line is maintained. Further, in the chemical solution supply unit 3, the medicine bottle 37 is set according to the set position information of the medicine bottle 37 displayed on the display panel 7 by reading the barcode of the medicine bottle 37 with a barcode reader. Therefore, the user opens the lid 34 with the handle 39 and places the medicine bottle 37 at a position displayed on the display panel 7 (an opening 35 a formed in the top plate 35 of the chemical solution supply unit 3). That's fine. Note that the dispensing unit 4 is moved to the origin position (the position at the far left corner of the apparatus body 1) only once when the power supply of the dispensing apparatus is turned on, and the origin taking is performed with the position as the reference position.

  When prescription data is input from a server or the like (not shown), the support unit 41 is moved, and the rod 43 is positioned in a row where the patient containers 16 to be dispensed are arranged. And the container 16 for patients located in the back side of an applicable row | line | column with the rod 43 is pressed ahead. The rod 43 is advanced until the front patient container 16 reaches the dispensing position and is detected by the first detection sensor 25. The patient container 16 pushed out to the dispensing position is held and positioned by the elastic guide 27. In this state, the weighing unit 29 is raised, the patient container 16 and the support plate 21 are weighed, and the value obtained by subtracting the weight of the patient container 16 is stored.

  Then, the support part 41 is moved to the upper position of the medicine bottle 37 in which the corresponding chemical solution is accommodated according to the prescription data. At this time, the information written in the RFID is read by the reader, and the chemical solution stored in the medicine bottle 37 is collated. Thereby, it can be confirmed whether the chemical | medical solution corresponds with the chemical | medical solution contained in prescription data. If the medicine bottle 37 is arranged according to the position displayed on the display panel 7, there should be no problem, but this check is performed to prevent human error.

  And if it is the chemical | medical bottle 37 in which the corresponding chemical | medical solution was accommodated, after turning the liquid dripping prevention part 47, the support part 41 will be dropped. As the support portion 41 is lowered, first, the rod 43 comes into contact with the pressure receiving portion 40c of the closing plate 40 as shown in FIG. The closing plate 40 is rotated by its own weight of the rod 43 to open the central hole of the cylindrical portion 34b. When the closing plate 40 is opened and the tip of the pressure receiving portion 40c abuts against the lid body 34, further rotation is prevented. At this time, as shown in FIG. 8B, the rod 43 slides with respect to the support portion 41 and only the nozzle 42 is lowered. Subsequently, as shown in FIG. 8C, the nozzle 42 passes through the center hole and reaches the inside of the medicine bottle 37. When the nozzle 42 reaches the liquid level of the chemical solution, as described above, the nozzle 42 is gradually lowered according to the decrease in the liquid level while sucking the chemical solution by a conventionally known method. Thereby, the chemical liquid can be sucked into the cylinder and temporarily stored without the outer peripheral surface of the nozzle 42 being immersed in the chemical liquid.

  When a predetermined amount of chemical liquid based on the prescription data is sucked into the cylinder through the nozzle 42 in this way, the support portion 41 (nozzle 42 and rod 43) is raised. At this time, the rod 43 moves to the original position by its own weight. As a result, the closing plate 40 is released from the pressed state by the rod 43 and closes the central hole of the cylindrical portion 34b of the lid 34. If the support part 41 raises to a predetermined position, it will move to the container 16 for patients applicable to a dispensing position.

  When the nozzle 42 reaches the dispensing position, the nozzle 42 is lowered and the tip portion is positioned in the patient container 16. Then, the chemical liquid sucked into the cylinder by advancing the piston is supplied into the patient container 16. When the supply of the chemical solution in the cylinder is completed, the nozzle 42 is raised again, and this nozzle 42 is moved to the cleaning unit 5 this time. At this time, the weighing unit 29 is raised, the patient container 16 and the support plate 21 to which the medicinal solution is supplied are weighed, and the result is stored. Then, the weight of the dispensed drug solution is calculated by subtracting the weight of the patient container 16 from the weighing result.

  When the nozzle 42 reaches the cleaning unit 5, the nozzle 42 is lowered to enter the inner container 51 of the cleaning container 48 (here, about 1 cm is submerged from the tip of the nozzle 42). Then, the piston is moved backward to suck the cleaning water into the cylinder. When the cleaning water is sucked, the nozzle 42 is once lifted and moved to the outer region formed between the inner container 49 and the outer container 50, and the cleaning process is performed by discharging the sucked cleaning water. The discharged washing water is collected into the waste water collection tank 10. This cleaning process may be performed a plurality of times, or once if it can be cleaned. When the cleaning process is completed, the nozzle 42 is raised. At this time, air is blown toward the nozzle 42 by the air supply tube 49 to remove the cleaning water and the chemical solution adhering to the nozzle 42.

  Hereinafter, similarly, the suction of the chemical solution from the drug bottle 37 by the nozzle 42, the dispensing of the sucked chemical solution into the patient container 16 and the cleaning of the nozzle 42 are repeated, and it corresponds to the patient container 16 based on the prescription data. Dispense a predetermined amount of each chemical solution. And every time it dispenses, the container 16 for patients and the support plate 21 are weighed in the weighing | measuring part 29, and the amount of dispensed chemical | medical solutions is calculated. However, the weighing may be performed only once after all the chemicals are dispensed.

  When the dispensing of the chemical solution to a certain patient container 16 is completed, the support portion 41 is moved, and the pressing pieces 19 in the row in which the patient containers 16 where the dispensing is completed are pushed forward by the rod 43. As a result, the patient container 16 at the top of the front where the dispensing of the drug solution has been completed is pushed out to the take-out portion 30 while being held by the elastic guide 27.

  The patient container 16 pushed out to the take-out portion 30 protrudes upward obliquely forward due to the inclination of the front inner surface. And this state is detected by the 2nd detection sensor 31, and LED32 lights. As a result, the user can see that the patient container 16 that has been dispensed has been dispensed.

  The user pulls out the shelf 14, places the discharged patient container 16 on the shelf 14, and attaches a cap. At this time, it is detected by the second detection sensor 31 that the patient container 16 has been taken out from the take-out unit 30, the journal printer 11 is activated, and the chemical information is printed. The printed chemical information is used for auditing. Further, the label printer 12 is activated, and the label on which the patient name and the barcode are printed is discharged. This label is attached to the patient container 16 for use. At this time, the patient container 16 is associated with information on the dispensed liquid medicine (name of the liquid medicine, dosage, etc.).

(3. Second embodiment)

(3-2. Container supply unit 102)
As shown in FIG. 10, in the container supply unit 102, the position of the extraction unit 130 is adjusted for each row in which the patient containers 120 are accommodated by size. Specifically, in the extraction part 130 corresponding to the container supply part 102 in which the small patient container 120 is accommodated, the side walls constituting the extraction part 130 are formed low. Thereby, it becomes easy for a user to hold | grip the container 120 for patients, and it becomes possible to perform an extraction operation | work easily. Moreover, the extraction part 130 is adjusted in the front-rear and top-bottom positions according to the size of the patient container 120. As the patient container 120 becomes larger, the position of the extraction portion 130 is adjusted forward and downward (in FIG. 10B, the position is adjusted as the extraction portion 130 is positioned on the right side. Yes.) Thereby, it is possible to make the gripping positions of all the patient containers 120 discharged to the extraction portion 130 substantially the same position so as to facilitate extraction. In addition, if the patient container 120 is discharged to any of the extraction units 130 of each container supply unit 102, it can be detected by a sensor (not shown) through the sensor hole 130a formed in the extraction unit 130. Therefore, it is not necessary to provide a plurality of sensors.

(3-3. Chemical solution supply unit 103)
As shown in FIGS. 11A and 11B, the chemical solution supply unit 103 does not include the lid 34 as in the first embodiment. In addition, the supply unit main body 133 is provided with a medicine bottle holding unit 135 including a pair of holding guides 134 so as to be substantially U-shaped instead of the opening 35a. The bottom surface 135a of the medicine bottle holding part 135 is inclined so as to be gradually lowered toward the front, and the medicine bottle 137 to be placed is inclined, that is, the outer peripheral surface of the medicine bottle 137 contacts the holding guide 134. Support in a state of being held in contact. The inclination angle of the medicine bottle 137 at this time is such that when the nozzle 142 is inserted vertically downward from the upper end opening of the medicine bottle 137, the tip portion of the nozzle 142 can reach the deepest position of the inclined medicine bottle 137. It is set to become. Thereby, when extracting a chemical | medical solution from the chemical | medical bottle 137 so that it may mention later, it can attract | suck to a state with almost no remaining amount, and it becomes possible to suppress the quantity discarded without being completely aspirated. . A closing plate 140 is attached to the upper end opening of each medicine bottle 137. The closing plate 140 includes a closing portion 140a that closes the upper end opening of the medicine bottle 137, and a pressure receiving portion 140b that extends obliquely from the closing portion 140a. As shown in FIG. 11C, the closing plate 140 is provided so as to be rotatable about the support shaft 141 and is supported in an inclined state by a spring 141a provided on the support shaft 141. It is biased in the closing direction. Thereby, the closed state by the closing plate 140 can be ensured. Similar to the first embodiment, the closing plate 140 is rotated to the open position against the urging force of the spring 141a by pressing the pressing receiving portion 140b with a rod (not shown) that moves up and down together with the nozzle 142. Move. As will be described later, the rod is supported by the support portion 145 so as to be lifted and lowered, and the pressure receiving portion 140b is pushed down by its own weight to rotate the closing plate 140 to the open position. Then, after opening the closing plate 140, the support portion 145 is slid, and only the nozzle 142 continues to descend. As a result, it is possible to allow the nozzle 142 to enter from the upper end opening of the medicine bottle 137 while keeping the closing plate 140 open.

  Here, the leftmost one medicine bottle 137 arranged in the front row of the medicine supply unit 103 contains dilution water for diluting the chemical solution. Here, tap water or purified water is used as dilution water. Instead of storing the dilution water in the medicine bottle 137, the cleaning water supplied from the cleaning water supply tank 110 can be used as the dilution water as it is.

  Further, it is preferable that the chemical solution stored in the medicine bottle 137 is periodically stirred using the nozzle 142. That is, the nozzle 142 is inserted into the medicine bottle 137, and the suction and discharge of the medicine liquid are repeated. Thereby, stirring of the chemical | medical solution in the medicine bottle 137 is attained. The used nozzle 142 may be washed.

(3-4. Dispensing part 104)
In the dispensing unit 104, as shown in FIG. 13, a nozzle 142 is detachable. That is, when the main body power supply is turned off, the dispensing unit 104 is lowered, and the screwing state of the nozzle holding unit 143 from the support unit 145 is released. And the nozzle 142 hold | maintained at this nozzle holding | maintenance part 143 is removed. Since the dispensing unit 104 is once lowered, a sufficient space for removing the nozzle 142 can be secured. Therefore, the attaching / detaching operation of the nozzle 142 can be performed smoothly. In addition, since the nozzle 142 can be easily attached and detached in this way, if it is periodically replaced with a new one, problems such as contamination are not likely to occur, and the nozzle 142 is clean. In addition, the rod which is not shown in figure is attached to the dispensing part 104 so that raising / lowering is possible similarly to the said 1st Embodiment.

The drainage port 151 is opened and is disposed on the side of the container supply unit 102 as shown in FIG. The upper end opening of the water supply pipe 150 is closed by a rotatable closing plate 152. Specifically, as shown in FIG. 14 (b), the closing plate 152 includes a closing portion 152 a that closes the upper end opening of the water supply pipe 150 and a pressure receiving portion 152 b that extends obliquely therefrom. In the normal state, the closing plate 152 rotates so as to close the upper end opening of the water supply pipe 150 by the closing portion 152a by the biasing force of the spring 152c. The closing plate 152 rotates when the pressure receiving portion 152b is pressed by the rod 143 provided in the dispensing unit 104 moved into the cleaning unit 105, and opens the upper end opening. In this state, by further lowering the dispensing unit 104, the cleaning water in the water supply pipe 150 can be sucked by the nozzle 142. Further, the cleaning container 148 itself can be removed with a single touch by rotating the lever 153. Thereby, the cleaning container 148 can be easily cleaned.

  In the cleaning unit 105 configured as described above, when the nozzle 142 is cleaned, the nozzle 142 and the rod 143 are moved into the cleaning container 148. Then, the rod 143 presses the pressing receiving portion 152b of the closing plate 152, and the closing plate 152 is rotated to open the upper end opening of the water supply pipe 150. Then, the nozzle 142 is moved down to suck the cleaning water and then lifted. Thereby, the closing plate 152 is rotated by its own weight, and the upper end opening of the water supply pipe 150 is closed. Here, the washing water sucked from the nozzle 142 is discharged. The discharged cleaning water flows down from the closing plate 152 to the lower side of the cleaning container 148 and is recovered to the recovery tank 111 through the drain port 151. The nozzle 142 is dried by air blown from the blower 144. As described above, when cleaning the nozzle 142, it is only necessary to move it up and down, and it is not necessary to move it in the horizontal direction as in the first embodiment. . The water supply pipe 150 that communicates with the cleaning water supply tank 109 may be directly connected to a general water supply (not shown), and the drainage port 151 that communicates with the recovery tank 110 may communicate with a general water supply drainage (not shown). By doing so, it is not necessary to carry and install heavy washing water supply tank 109 and recovery tank 110.

(3-6. Sterilization unit 160)
As shown in FIG. 15 (b), the sterilizing unit 160 is configured by arranging a pair of sterilizing lamps 162 inside a casing 161 made of a metal material. An insertion hole 161a that can be inserted is formed. The sterilizing unit 160 is disposed in front of the cleaning unit 105 and sterilizes the nozzle 142 inserted from the insertion hole 161a.

(4. Operation)
Next, the operation of the dispensing apparatus according to the second embodiment will be described.

  Various settings can be made before the dispensing process. That is, setting whether to perform automatic dilution (setting 1), setting whether to use or dilute the stock solution (setting 2), setting whether to dilute based on a single dose (setting 3), number of days The setting of dilution (setting 4), the setting of the diluted drug depending on the age of the patient (setting 5), and the setting of the scale display on the patient container 120 (setting 6) can be performed.

In setting 4, the number of days for dilution (specified number of days) is set. In setting 5, an appropriate diluent is set according to the age of the patient. In setting 6, a method of providing a scale to be printed on a label attached to the patient container 120 is set.

  When the program is started by turning on the power, a login dialog screen shown in FIG. 16 is displayed on the display panel 7. On the login dialog screen, input fields for a user ID and a password are displayed. When both are input and the login button is operated, the collation is performed, and if it is registered data, the liquid medicine dispensing monitor screen shown in FIG. 17 or the liquid medicine dispensing detail monitor shown in FIG. Display one of the screens. All screens have the same display contents, but display forms are different. That is, the former highlights the column displaying patient names, while the latter highlights the column displaying drug names. In the initial setting, any screen can be selected, and the screen can be displayed based on the screen information at the end of the previous time.

  When the detail button 170 is operated on the liquid medicine dispensing monitor screen shown in FIG. 17, the liquid medicine dispensing detailed monitor screen shown in FIG. 18 is switched, and the dispensing monitor button 171 is pressed on the liquid medicine dispensing detailed monitor screen shown in FIG. When operated, the liquid medicine dispensing monitor screen shown in FIG. 17 is switched.

  In addition, the liquid medicine dispensing detail monitor screen includes a patient button 172, a division field 173, a days field 174, an application container field 175, a usage field 176, a medicine name 177, a sequential reading mode button 178, an automatic dispensing mode button 179, A device connection field 180, a stop button 181, a hold button 182, an unprocessed list button 183, and a reissue button 184 are included.

  When the patient button 172 is touch-operated, a patient details dialog screen is popped up as shown in FIG. 19 so that the patient's name, height, ID, etc. can be confirmed. When the division field 173 is touched, a division dialog screen is popped up as shown in FIG. 20, and the capacity of the applied container relative to the total dispensed volume, the dispensed volume after the division, the capacity of the applied container, etc. can be confirmed. ing. When the number of days column 174 is touched, a days dialog screen including a date for selecting the number of prescription days is popped up as shown in FIG. When the application container column 175 is touch-operated, as shown in FIG. 22, a dosing container selection dialog screen, which is a list of applicable patient containers 120 and their capacities, is popped up. When the usage column 176 is touch-operated, a usage selection dialog screen including the timing of taking is displayed as shown in FIG. When the medicine name 177 is touched, a medicine selection dialog screen is popped up as shown in FIG. In this medicine selection dialog screen, any one or all of medicines (chemical solutions), additives, and diluted water can be selected and displayed. When the sequential reading mode button 178 is touch-operated, a reception mode change screen is popped up as shown in FIG. 25 so that a prescription data reception mode can be set. When the dispensing mode selection button 179 is touch-operated, a dispensing mode selection screen for selecting either automatic dispensing or manual dispensing is popped up as shown in FIG. The button display is automatic dispensing when manual dispensing is selected, and manual dispensing when automatic dispensing is selected. When the device connection field 180 is touched, a communication information screen including a list of devices connected to the dispensing device such as a barcode reader and a printer is popped up as shown in FIG. When the stop button 181 is touch-operated, as shown in FIG. 28, the dispensing apparatus is stopped. At this time, a medicine collection confirmation dialog screen that is a warning display for stopping the dispensing process is displayed in a pop-up manner. When the hold button 182 is touch-operated, as shown in FIG. 29, a hold list screen that is a list of patients whose dispensing process is held is popped up. When the unprocessed list button 183 is touched, an unprocessed list screen is popped up as shown in FIG. The unprocessed list screen displays a list of patients that have not been subjected to the dispensing process, and by selecting each patient, prescription data is displayed for that patient. When the reissue button 184 is touched, a reissue screen pops up as shown in FIG. 31 so that the prescription data can be reissued while confirming its contents.

  In the dispensing process, as shown in the flowcharts of FIGS. 32 and 33, it is first determined whether or not dispensing can be performed based on prescription data input from a server that is a host system (step S1). For example, when a certain drug solution A is to be taken in multiple doses, the prescription amount is only given for the whole, and if the dose for each dose is not included, it cannot be dispensed to decide.

  If it is determined that dispensing cannot be performed, the prescription data is returned to the server, and vertical division processing is performed (step S2). In the vertical division process, the entire prescription amount (dispensed total amount) is decomposed into a plurality of prescription data obtained by decomposing each dose. For example, for a patient, when prescribing medicinal solution A 2 ml in the morning, 1 ml in the daytime, and 3 ml in the evening, prescription 1 is medicinal solution A, 2 ml in the morning, prescription 2 is medicinal solution A, 1 ml in the daytime, prescription 3 is medicinal solution A, 3 ml in the evening And Thereby, it becomes prescription data which can be handled by dispensing processing.

  Next, based on prescription data, the prescription form of a chemical | medical solution is confirmed (step S3). That is, it is determined whether the chemical solution is supplied as an undiluted solution or diluted. In addition, about a certain chemical | medical solution, when both a stock solution and dilution are mixed, it treats as a stock solution.

  When it is determined that the prescription form is an undiluted solution, it is determined which of the dispensing methods is selected based on the setting 2 (step S4).

  If the dispensing method is set to (2-1) all undiluted solutions, on the basis of the setting 3, (3-1) is the case where the single dose contains a decimal, and dilution is performed? Alternatively, (3-2) it is determined whether the single dose includes a decimal number and no dilution is performed (step S5).

  In the case of (3-1), the dilution amount is determined so that the single dose is an integer larger than the value and closest (step S6). For example, when the single dose of the chemical solution A is 4.5 ml, the dilution amount is 0.5 ml, and the single dose is an integer of 5 ml. However, even if the single dose includes a decimal, the daily dose may be calculated, and if the obtained value does not include a decimal, it may not be diluted. Further, when the daily amount includes decimal numbers, the dilution amount may be determined so as to be an integer larger than that value and closest.

  In the case of (3-2), that is, even if a fraction is included in a single dose, the patient containers 120 and the number are calculated according to the prescription data when not diluted (step S7).

  When the dispensing method is set to (2-2) medicine bottle delivery, and the fraction is set to the stock solution dispensing bottle delivery, the delivery method is determined for each medicine contained in the prescription data (step S8).

  For example, when the prescription amount of the liquid medicine A is 60 ml × 3 times × 14 days = 2520 ml and the prescription amount of the liquid medicine B is 45 ml × 3 times × 14 days = 1890 ml, Since the volume is 500 ml, the number of bottles that can be dispensed in the medicine bottle is 2520 ml / 500 ml = 5.04, and is determined to be 5. The fraction of 20 ml is dispensed into the patient container 120 and dispensed. On the other hand, since the capacity of the medicine bottle containing the medicine B is 300 ml, the number of medicine bottles that can be dispensed in the medicine bottle is 1890 ml ÷ 300 ml = 6.3, which is determined to be six. The fraction of 90 ml is dispensed into the patient container 120 and dispensed.

  When the dispensing method is set to (2-3) dilution dispensing within the specified number of days, and the stock solution dispensing after the specified number of days, the specified number of days set is the same as when the prescription form described below is dilution. A dilution amount is calculated, and a value obtained by adding the dilution amounts is set as a dispensing amount (step S9). For the portion exceeding the designated number of days, the size and number of patient containers 120 are determined in the same manner as described above (step S10).

  When it is determined that the prescription form is dilution (Step S3: Dilution), based on the setting 4, (4-1) the number of days is equally divided, or (4-2) dilution dispensing in the specified number of days, After the designated number of days, it is determined whether the preparation is a stock solution (step S11).

  In the case of (4-1), the dilution amount is calculated as follows and dilution dispensing is performed (step S12).

(1) The total amount of prescriptions for all chemicals included in the prescription data is calculated.
(2) Based on the obtained calculated value, the patient container 120 having the same capacity as this calculated value, or if there is no such patient container 120, a patient container 120 having a size larger and closest thereto Select.
(3) The single dose of each chemical solution is calculated, and the total value of the single dose of all the chemical solutions is obtained.
(4) Referring to the master file of the patient container 120, the dose per division of each patient container 120 is calculated.
(5) Compare the total dose value of all the chemicals obtained in (3) with the dose value per scale calculated in (4). Determine the largest and closest dose value.
(6) The total value calculated in (3) is subtracted from the dose value calculated in (4), and the obtained value is multiplied by the number of fractions (number of doses per day) and the number of days. Calculate the dilution amount per bottle.

  Specifically, the case where the dilution amount is calculated from the master file of the patient container 120 shown in Table 2 for the prescription data shown in Table 1 will be described. FIG. 12 shows the patient container 120 with the 100 ml scale shown in the table.

  (1) The total prescription amount is (dose 10 ml x 3 times x 7 days for drug A) + (12 ml x 3 times x 7 days for drug B) = 462 ml.

  (2) As the size of the patient container 120, the total prescription amount is 462 ml, so 500 ml is selected.

  (3) The total value of the single dose of all the chemical solutions is 10 ml of the single dose of the chemical solution A + 12 ml = 12 ml of the single dose of the chemical solution B.

  (4) The dose per scale of each patient container 120 is as shown in Table 3.

  (5) The 22 ml value calculated in (3) is compared with each dose value calculated in (4), and the dose value is determined to be 23.8 ml, which is the closest value larger than 22 ml.

  (6) The dilution amount per one container 120 for patients is obtained by subtracting 22 ml calculated in (3) from 23.8 ml obtained in (5), and adding 3 fractions and 7 days to 1.8 ml obtained. To obtain 37.8 ml.

  Thus, when the medicinal solutions A and B and the diluting solution are stored in the selected patient container 120, the volume can be exactly 500 ml, and one scale corresponds to one dose.

  In the case of prescription data shown in Table 4, when dispensing into patient containers 120 of the size shown in Table 5, the dilution amount is calculated as follows.

  That is, the total amount of medicinal solution A is 4.5 ml × 3 doses × 14 days = 189 ml, and the total amount of medicinal solution B is 3.0 ml × 3 doses × 14 days = 126 ml, so the total amount is 189 ml + 126 ml = 315 ml. As shown in Table 5, the maximum size of the patient container 120 that can be used is 300 ml. Therefore, two dispensing objects are used, and 315 ml ÷ 2 = 157.5 ml is obtained as a dispensing amount per bottle.

  When automatic dilution is on (1-1), a 200 ml patient container 120 having a size closest to 157.5 ml calculated as a dispensing amount per bottle is selected. Table 6 is obtained from Table 5 as the dose per division.

  Since the total of the single doses of the chemicals A and B is 7.5 ml, the closest value of 9.5 ml is selected, and from the difference of 9.5 ml-7.5 ml = 2.0 ml, Multiply 3 doses and 7 days (2.0 ml × 3 × 7) to obtain 42.0 ml, which is the dilution per patient container 120.

  In the case of (4-2), in the example of Table 4 above, if the designated number of days is 7 days, dilution dispensing (step S13) and stock solution dispensing (step S14) are performed as follows.

  In diluted dispensing, the total amount for 7 days of the chemicals A and B is calculated in the same manner as described above. That is, the total amount of medicinal solution A for 7 days is 4.5 ml × 3 doses × 7 days = 94.5 ml, and the total amount of medicinal solution B for 7 days is 3.0 ml × 3 doses × 7 days = 63.0 ml, so the total amount for 7 days is 94.5 ml + 63.0 ml = 157.5 ml. Therefore, a 200 ml container 120 for patients is selected, and 42.0 ml is obtained as a dilution amount for 7 days. As a result, if 157.5 ml of the stock solution and 42.0 ml of the diluted solution are accommodated in the selected 200-ml patient container 120, the volume is almost 199.5 ml.

  In the stock solution dispensing, 157.5 ml, which is a value obtained by subtracting the total amount for 7 days from the total amount for 14 days of the chemical solutions A and B, is stored in a 200 ml patient container 120. And when a patient actually uses, it dilutes with a diluent (generally tap water), and uses it as 200 ml. Thereby, until it is actually used, it is possible to prevent invasion of germs and the like, and it is clean.

  As described above, when each series of processing is completed, the diluent is selected based on the age information included in the prescription data (step S15). Here, it is selected whether it corresponds to the dilution liquid for infants, the dilution liquid for adults, or the dilution liquid for elderly people. For example, a syrup is selected in the case of an infant dilution, and tap water is selected in the case of an adult dilution. If the age cannot be specified, select an adult diluent.

  Finally, the journal printer is driven to print a label (step S16). For printing on the label, the unit of dose according to setting 6 is used. Here, either the ml representation or the scale representation is printed.

(Other embodiments)
In addition, this invention is not limited to the structure described in the said embodiment, A various change is possible.

  For example, in the said embodiment, although the chemical | medical bottle 37 was mounted on the flat surface by the chemical | medical solution supply part 3, you may make it incline the surface to mount. However, the inclination angle needs to be such that the tip of the nozzle 42 that has entered from the upper opening of the drug vial 37 can reach the vicinity of a deep position on the bottom surface of the tilted drug vial 37. According to this, the amount of the chemical solution remaining in the medicine bottle 37 sucked by the nozzle 42 can be reduced as compared with a flat case. That is, it is possible to suppress the amount of the chemical liquid that is wasted.

  Alternatively, the chemical solution in the drug bottle 37 may be agitated by repeating suction and discharge of the chemical solution in the drug bottle 37. According to this, even if it is a type of chemical solution that tends to precipitate, the chemical solution to be sucked can be homogenized without adding a special configuration.

  In the cleaning unit 5, the air is blown by the air supply cylinder 49 to remove the cleaning water or chemical liquid adhering to the nozzle 42. However, before the air is blown, the nozzle 42 is repeatedly moved up and down. The adhering liquid may be dropped in advance by vibrating. Thereby, the time for removing the adhering liquid in the air supply tube 49 can be shortened or eliminated.

  In addition, although the patient container 16 at the dispensing position is merely confirmed by the camera, an image at the time of dispensing each chemical solution may be stored together with the patient data and prescription data so that it can be viewed as an audit or a history. Thereby, even when it is a case where a plurality of liquid medicines are dispensed to the patient container 16, when it is determined whether or not the liquid medicine is appropriately dispensed by the stored image data or the like every time each liquid medicine is supplied. It can be used.

In the dispensing unit 104, the nozzle 142 and the pump 146 are connected by a tube. However, when the nozzle 142 is moved up and down, the tube may be loosened, and the cleaning liquid may remain. For this reason, as shown in FIG. 34, by fixing the pump 146 to the upper part of the nozzle holding part 143, the nozzle 142 and the pump 146 may be directly connected, and both may be raised / lowered integrally.
Further, even when the nozzle 142 and the pump are not directly connected and are connected by a tube (not shown), it is possible to raise and lower the tube so that the tube does not loosen.

In addition, the concentration of the chemical solution is not considered in the dilution, but it is preferable to consider the concentration of the diluted chemical solution. For example, the volume of the stock solution may be diluted within a range of 1.5 to 2 times. .
Table 7 shows the case where A medicine and B medicine are prescribed 12 times in the same patient container 16.

  Since the total amount of medicine A and medicine B accommodated in the patient container 16 is 66 ml, the minimum value of dilution is 66 (ml) × 1.5 = 99 ml, and the maximum value is 66 (ml) × 2 = 132 ml. Become. Therefore, the patient container 16 to be employed needs to satisfy 99 ml to 132 ml. Therefore, the patient container 16 is searched from the smaller size according to Table 2, and the 100 ml patient container 16 which is the minimum size satisfying 99 ml to 132 ml is selected. In addition, from Table 5, the “number 4” scale that satisfies 12 times, that is, the scale number 12 is selected from the 100 ml patient container 16. With a capacity of 100 ml and a scale number “4”, the capacity per scale is 8.33 ml. Therefore, the difference between the volume per division of the scale “4” and the single dose is 8.33 (ml) −5.5 (ml) = 2.83 ml. Therefore, the total amount of the diluent in the 100 ml patient container 16 containing the A drug and the B drug is 2.83 (ml) × 12 = 33.96 ml≈34 ml.

  In this way, in the above example, the concentration of the drug solution after dilution is taken into consideration within a certain range, so that when taking the patient, it is close to the undiluted solution and bitter, such as being difficult to drink. There is nothing.

  Further, in addition to the contents displayed on the liquid medicine dispensing monitor screen shown in FIG. 15, as shown in FIG. 33, a “priority medicine form” button 185, a “stock solution dispensing” button 186, and a “dilution dispensing” button 186 may be displayed. By touching the “priority medicine form” button 185, dispensing can be performed in a medicine form registered in advance by the user in accordance with the internal regulations of each pharmacy. Examples of the drug form include drug A being dispensed as a stock solution, drug B being dispensed after predetermined dilution, and the like. Further, by touching the “stock solution dispensing” button 186, dispensing with the stock solution can be performed. In this case, as described above, when the patient actually uses it, it is diluted with a diluent (generally, tap water). In addition, by touching the “dilution dispensing” button 187, dilution dispensing can be performed. In this case, the amount of the diluted solution can be determined by any of the methods already described (any method may be selected).
