FIG.

-1st Embodiment-
Next, the present invention will be described with reference to two embodiments. First, a first embodiment will be described. FIG. 1 is a schematic view showing a medicine collecting mechanism 1 according to the first embodiment.

  The medicine collecting mechanism 1 of the present embodiment inserts the injection needle S1 from the outside of the medicine container B into the insertion part B1 into the medicine container B having the insertion part B1 through which the injection needle S1 of the syringe S can be inserted. The medicine is moved between the medicine container B and the syringe S (that is, the medicine is drawn from the medicine container B to the syringe S via the injection needle S1, or the medicine is moved from the syringe S to the medicine container B via the injection needle S1. Used when discharging. The medicine container B is, for example, a vial bottle. When the medicine container B is a vial bottle, the insertion portion B1 is, for example, a resin lid made of rubber or the like attached to the medicine container B in a liquid-tight and air-tight manner. This lid is attached, for example, by caulking a metal plate or a resin plate on the outer peripheral portion, while the main body of the medicine container B is made of glass or resin.

  Here, various medicines correspond to the medicines targeted in the present embodiment. In particular, the drug collecting mechanism 1 of the present embodiment is effective for a drug that is toxic and has a bad effect on the human body when taken for a long period of time even if the amount is small. An example of such a drug is an anticancer drug. Many anticancer drugs have been reported to be carcinogenic.

  Since the medicine is moved by the syringe S, the medicine contained in the medicine container B needs to be in a liquid state at least at the time of moving to the syringe S. The drug may be in a liquid state from the beginning, or dissolved by injecting a solvent such as purified water with a syringe S into a drug container B containing a solid (eg, powder, granule, or fibrous) drug. Into a liquid solution.

  The medicine collecting mechanism 1 of the present embodiment mainly includes a jacket 2, a fluid supply unit 3, and a fluid recovery unit 4. The jacket 2 is an adapter (adapter) to which both the medicine container B and the syringe S can be attached, and includes a jacket main body 21, an introduction part 24, and a lead-out part 25.

  The jacket body 21 is a cylindrical (for example, cylindrical) portion and has a space inside. The jacket body 21 can be attached to the medicine container B from outside the medicine container B so as to cover the insertion portion B1 tightly (at least liquid-tight, and in this embodiment, liquid-tight and air-tight). The jacket main body 21 includes a medicine container joining portion 22 joined to the medicine container B. The medicine container joining part 22 of the present embodiment is provided at the lower end of the jacket main body 21 in the figure, and the packing protrudes from the inner periphery. The medicine container B is attached to the jacket main body 21 by bringing this packing into close contact with the medicine container B outside the insertion portion B1.

The jacket main body 21 includes a syringe joint 23 joined to the syringe S. The syringe joint 23 of the present embodiment is provided at the upper end in the figure of the jacket main body 21, and the packing protrudes from the inner periphery. The syringe S is attached to the jacket main body 21 by bringing this packing into close contact with the outer peripheral surface of the cylindrical portion of the syringe S. In the state of being attached to the jacket main body 21, the syringe S is relatively movable in a direction approaching and separating from the medicine container B. In the present embodiment, the syringe S is movable in the axial direction (the vertical direction shown by the arrow). Therefore, the injection needle S1 is inserted through the insertion portion B1 from outside to inside of the medicine container B while the medicine container joint portion 22 is brought into close contact with the medicine container B and the syringe S is mounted on the jacket main body 21. The operation of sucking the medicine from the medicine container B to the syringe S can be performed. In addition, the jacket main body 21 may be formed in a bellows shape or the like that can expand and contract in the moving direction of the syringe S. Thereby, even if the syringe S is moved in the axial direction, the state where the syringe joint 23 and the syringe S are in close contact can be maintained.

  With the jacket main body 21 configured as described above, the insertion portion B1 of the medicine container B and the injection needle S1 are arranged in the internal space of the jacket main body 21. This arrangement is made tight (at least liquid-tight, in this embodiment liquid-tight and air-tight) with respect to the outside of the jacket body 21. For this reason, even if aerosol is generated, the aerosol can be kept in the internal space of the jacket 2 and the scattering or outflow of the drug to the outside of the jacket body 21 can be prevented. Also, even after the syringe S is separated from the medicine container B, even if the medicine remains on the lid of the medicine container B or the outer surface of the injection needle S1, this medicine is retained in the internal space of the jacket 2 and will be described later. Before the fluid is supplied by the fluid supply unit 3, the fluid is prevented from flowing out of the jacket body 21.

  The introduction portion 24 is a portion penetrating through the jacket body 21. The introduction section 24 of the present embodiment is a short pipe that penetrates the jacket main body 21 in the radial direction and communicates with the internal space of the jacket main body 21. However, the form is not limited. The fluid can be introduced into the jacket main body 21 through the introduction section 24. In the present embodiment, one introduction portion 24 is provided below the jacket body 21. However, it is not limited to this.

  The lead-out part 25 is also a part penetrating the jacket main body 21. The lead-out portion 25 of the present embodiment is a short pipe that penetrates the jacket body 21 in the radial direction and communicates with the internal space of the jacket body 21. However, the form is not limited. The fluid can be led out from the inside of the jacket main body 21 through the lead-out part 25. In the present embodiment, two lead-out portions 25, 25 are provided above and below the drawing. However, it is not limited to this.

Although not shown, the fluid supply unit 3 includes a tank for holding the fluid, and a fluid moving unit such as a pump for moving the fluid F1 (see FIG. 1) in the tank to the jacket body 21. The fluid used in the present embodiment is purified water. The fluid is not particularly limited as long as the fluid can be removed from a portion of the drug container B and the syringe S which are located inside the jacket 2 and which comes into contact with the fluid, for example, by washing. For example, a gas such as air may be used as the fluid, and the medicine supplied inside the jacket 2 may be blown off with the fluid supplied from the fluid supply unit 3 to be discharged from the discharge unit 25.

  The fluid recovery unit 4 is provided for recovering a fluid (including a drug remaining inside the jacket main body 21) supplied to the inside of the jacket main body 21 by the fluid supply unit 3, and is connected to the outlet 25. I have. The fluid recovery section 4 of the present embodiment has a tank for storing a fluid. This tank has a sufficient capacity for the amount of fluid supplied by the fluid supply unit 3.

The collection pipe 6 is provided between the jacket body 21 and the fluid collection part 4. In the present embodiment, since two outlets 25 are provided, each outlet 25 is provided with the recovery pipe 6. A recovery pipe 6A connected to the outlet 25 on the medicine container B side (lower side in the figure) and a recovery pipe 6B connected to the outlet part 25 on the syringe S side (upper side in the figure) are provided. Further, in the present embodiment, the on-off valve 7 is provided on the collection pipe 6A, and this on-off valve 7 can be closed if necessary. When the fluid is supplied by the fluid supply unit 3, the on-off valve 7 is closed so that the inside of the jacket body 21 is filled with the supplied fluid. At the same time, the fluid is recovered by the fluid recovery unit 4 via the recovery pipe 6B. A fluid introduced from an introduction portion 24 provided at a lower portion of the jacket main body 21 is caused to flow upward from below inside the jacket main body 21, and then a lead-out portion 25 provided at a lower portion of the jacket main body 21. Can be derived from By filling the inside of the jacket main body 21 with the supplied fluid in this way, the lid can be brought into contact with the fluid on the lid of the medicine container B to which the medicine has adhered or the outer surface of the syringe S, so that the medicine can be effectively removed. Can be done. By forming a fluid flow that flows upward from below inside the jacket main body 21, the medicine can be effectively removed.

After the treatment, the treated air can be released to the outside. When the fluid is a liquid, the fluid recovery unit 4 of the first embodiment can be provided.

-Drug collection method-
Next, a method of collecting a medicine will be described. Hereinafter, an example using the medicine collecting mechanism 1 of the first embodiment or the second embodiment will be described. However, this method can be implemented without necessarily using the medicine collecting mechanism 1 of the first embodiment or the second embodiment. The subject of the following steps is a drug preparer such as a pharmacist.

  First, the jacket 2 is attached to the medicine container B so as to cover the insertion portion B1 from outside the medicine container B densely. At this time, the medicine container joint 22 is brought into close contact with the medicine container B. At the same time, a step of densely inserting a part (for example, a cylindrical part) of the syringe S from the distal end side of the injection needle S1 into the jacket 2 is performed. At this time, the syringe joint 23 is brought into close contact with the injection needle S1. The attachment of the jacket 2 to the medicine container B and the insertion of a part of the syringe S into the jacket 2 do not matter before or after the implementation.

  Next, a step of inserting the injection needle S1 of the syringe S from the outside of the medicine container B into the insertion portion B1 and moving (sucking) the medicine between the medicine container B and the syringe S is performed.

  Next, for example, when using the medicine collecting mechanism 1 of the first embodiment, the injection needle S1 is pulled out from the insertion portion B1 of the medicine container B. At the same time, a step of recovering the fluid from the inside of the jacket 2 while supplying the fluid to the inside of the jacket 2 is performed. The supply of the fluid to the inside of the jacket 2 and the collection of the fluid from the inside of the jacket 2 may be performed at the same time, or may be performed before and after. Further, withdrawing the injection needle S1 and collecting the fluid from the inside of the jacket 2 while supplying the fluid to the inside of the jacket 2 may be performed at the same time, or may be performed before and after.

Further, for example, when using the medicine collecting mechanism 1 of the second embodiment, the injection needle S1 is pulled out from the insertion portion B1 of the medicine container B. At the same time, a step of sucking the fluid from the inside of the jacket 2 while introducing the fluid into the jacket is performed. Note that the introduction of the fluid into the jacket 2 and the suction of the fluid from the inside of the jacket 2 may be performed at the same time, or may be performed before or after. Further, the withdrawal of the injection needle S1 and the suction of the fluid from the inside of the jacket 2 may be performed simultaneously, or may be performed before or after.

-Possibility of change of embodiment-
Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various changes can be made without departing from the spirit of the present invention.

  For example, the drug targeted in each of the above embodiments was toxic, and was a drug (dangerous drug) that, even if in a very small amount, had a bad effect on the human body when taken for a long period of time. However, the present invention can also be applied to drugs that are not such dangerous drugs.

  Further, the medicine container B targeted in each of the above embodiments is a vial bottle, but may be, for example, an ampoule bottle whose head is cut and opened, and the type of the medicine container B is not limited. . In the case of an ampoule bottle, an opening formed by cutting the head corresponds to the insertion portion.

  In addition, the jacket main body 21 of each of the above embodiments is configured to be in close contact with the outer peripheral surface of the cylindrical portion of the syringe S. However, the present invention is not limited to this, and may be configured to be in close contact with the outer peripheral surface of the injection needle S1.

  FIGS. 3A and 3B show a partially modified configuration of the first embodiment. As described above, after the packing in the medicine container joining portion 22 is exposed upward, the upper end of the packing can be made to coincide with the lead-out portion 25. As shown in FIG. 3B, the packing at the medicine container joining portion 22 is pressed by a plurality of stoppers 27 intermittently protruding from the inner peripheral surface of the jacket 2, and the upper surface of the lid of the medicine container B is connected to the lead-out portion 25. And the height of the lower surface of the inside. According to this, since the upper surface of the lid of the medicine container B and the height of the inner lower surface of the lead-out portion 25 match, when the fluid is led to the lead-out portion 25 from the internal space of the jacket body 21, It is possible to suppress the fluid from remaining in the internal space. In addition, since the plurality of stoppers 27 are located at positions where the openings of the lead-out portion 25 to the jacket main body 21 are not blocked, the remaining of the fluid can also be suppressed at this point. In addition, in the illustrated example, the lead-out part 25 is provided at a position lower than the introduction part 24, but the heights of both may be the same.

  Further, the diameter of the medicine container joint 22 or the syringe joint 23 can be made variable.

  Further, a sensor for detecting a medicine may be provided on the jacket 2 so as to determine whether or not the medicine has been reliably removed from the jacket 2 by a fluid.
