  Here, a method for automatically dissolving the drug 5 in the solution 2 using the stirring device 14 will be described with respect to the drug container 1 storing the solution 2 and the drug 5 in the present embodiment.

  FIG. 5 is a flowchart showing an operation of dissolving the drug in the solution using the stirring device 14 in the drug container storing the solution and the drug according to the first embodiment of the present invention.

  First, the drug stirring unit 9 of the drug container 1 is set in the recess 16 of the casing 17 of the stirring device 14 (S1 in FIG. 5). At this time, the suspension arm 22 is passed through the holding portion 12 and is held from above.

  Next, the type and amount of the solution 2 and the medicine 5 stored in the medicine container 1 are input to the control unit 20 of the stirring device 14 (S2 in FIG. 5). In the present embodiment, a barcode on which information including the type and amount of the dissolved solution 2 and the medicine 5 stored in advance is read by a barcode reader (not shown) mounted on the stirring device 14. The information read by the bar code reader is input to the control unit 20 to input the types and amounts of the dissolution liquid 2 and the drug 5.

  Next, based on the type and amount of the dissolved solution 2 and the medicine 5 that are input, the first rotation speed N1 for rotating the stirring bar 8 and the first rotation time (T1) for rotating the stirring bar 8 are set. At the same time, the rotational operation of the drive unit 15 is started, and control is performed so that the rotational speed of the stirrer 8 becomes the first rotational speed (N1) (S3 in FIG. 5, first stirring operation). In the present embodiment, the dissolution experiment of the dissolution liquid 2 and the drug 5 is performed in advance, and the rotation speed and rotation speed of the stirrer 8 for dissolving the drug 5 sufficiently dissolved in the dissolution liquid 2 are obtained. The rotation speed and rotation time obtained in the dissolution experiment are respectively set as a first rotation speed N1 and a first rotation time (T1) in a memory (not shown) inside the control unit 20 of the stirring device 14 in advance. I keep it.

  Therefore, based on the type and amount of the solution 2 and the medicine 5 read by the barcode reader, the first rotation speed N1 for rotating the stirrer 8 and the first rotation time for rotating the stirrer 8 ( T1) can be determined.

  Next, the time (T) from the start of the first stirring operation is measured, and the time (T) from the start of the first stirring operation is determined as the first rotation time ( It is determined whether or not (T> T1) has elapsed since T1) (S4 in FIG. 5). If T> T1, the process proceeds to the next step. If T <T1, the first stirring operation in S3 in FIG. 5 is continued.

  In this embodiment, the control unit 20 of the stirring device 14 measures and determines the time (T) from the start of the first stirring operation.

  Next (when T> T1 described above), the rotational speed of the stirrer 8 is decreased (S5 in FIG. 5). In this embodiment, when this S5 is reached, it is set to half (0.5 × N1) of the first rotation speed N1 described above. Moreover, in this embodiment, this operation | movement was performed by the control part 20 of the stirring apparatus 14. FIG. Here, the rotation speed of the stirrer 8 is decreased because the vortex 21 (see FIG. 4) in the drug stirring unit 9 is reduced, and this vortex 21 affects the turbidity measurement in the next step. This is to prevent it from occurring.

Next, in order to confirm whether or not the drug 5 is completely dissolved in the solution 2, the turbidity of the solution 2 inside the drug stirring unit 9 is measured by the turbidity measuring unit 18 of the stirring device 14 (FIG. 5 in S6).
Next, it is determined whether or not the turbidity of the solution 2 inside the drug stirring unit 9 is equal to or higher than a desired turbidity (S7 in FIG. 5). In the present embodiment, this determination is made by the control unit 20 of the stirring device 14.

  In the present embodiment, the dissolution experiment of the dissolution liquid 2 and the drug 5 is performed in advance, and the turbidity when the drug 5 is completely dissolved in the dissolution liquid 2 is measured. The desired turbidity is stored in advance in a memory (not shown) inside the control unit 20, and the stored desired turbidity is compared with the actually measured turbidity for determination.

If the turbidity of the solution 2 in the drug stirring unit 9 is equal to or higher than the desired turbidity, the rotation of the stirring bar 8 is stopped (S8 in FIG. 5). The notification unit 19 notifies the outside of the stirring device 14 that the dissolution of the dissolution liquid 2 and the drug 5 has been completed (S9 in FIG. 5). In this embodiment, the structure which lights an indicator lamp as the alerting | reporting part 19 was used.
If the turbidity of the solution 2 in the drug stirring unit 9 is less than the desired turbidity, the second rotation speed N2 for rotating the stirring bar 8 and the second rotation time for rotating the stirring bar 8 (T2) is determined, and the rotational operation of the drive unit 15 is started, and control is performed so that the rotational speed of the stirrer 8 becomes the second rotational speed (N2) (S10 in FIG. Stirring operation). In the present embodiment, the second rotational speed N2 is the same rotational speed as the first rotational speed N1, and the second rotational time (T2) is 5 minutes.

  Next, the time (Ta) from the start of the second stirring operation is measured, and the time (Ta) from the start of the second stirring operation is the second rotation time ( It is determined whether or not (T> T2) has elapsed since T2) (S11 in FIG. 5). If Ta> T2, the process proceeds to step S5 in FIG. 5 (the rotational speed of the stirrer 8 is decreased), and then the turbidity of the solution 2 inside the drug stirring unit 9 is measured. If Ta <T2, the second stirring operation of S11 in FIG. 5 is continued. That is, the second stirring operation is continued until the turbidity of the solution 2 in the drug stirring unit 9 becomes equal to or higher than the desired turbidity.

  In this embodiment, when the drug 5 is dissolved in the solution 2, the whole becomes cloudy. However, when the drug 5 is dissolved in the solution 2, the turbidity is increased. The measurement unit 18 measures this transparency.

  As described above, according to the present embodiment, the medicine 5 in the medicine storage chamber 6 is supplied to the solution 2 in the medicine adjustment chamber 3 through the medicine supply path 4, and then provided in the medicine stirring unit 9. The drug 5 can be automatically dissolved in the dissolving liquid 2 simply by rotating the stirrer 8, and the workability is extremely high.

  In particular, when the drug 5 is, for example, a drug 5 used for instillation treatment of cancer, the toxicity is very high, and there is a possibility that the medical staff himself may be violated by toxicity during work. In this case, the solution 2 is stored in the drug adjustment chamber 3 and the drug 5 is stored in the drug storage chamber 6 in a state of being cut off from the outside air. It is possible to prevent the person himself / herself from being violated by the toxicity of the drug.

  Then, after the drug 5 is automatically dissolved in the dissolution liquid 2, the drug container 1 is inverted, and a hanging arm (not shown) used during infusion is passed through the holding part 11 and held. An infusion needle (not shown) is connected to the medicine administration port 7 and then the patient is infused.

  As described above, the present invention is connected to the drug adjustment chamber storing the solution, the drug adjustment chamber via the drug supply path, the drug storage chamber storing the drug, and the drug adjustment chamber. And a drug agitating portion in which a stirrer is housed, and is connected to the drug adjusting chamber, so that the workability is high.
