Has been. Moreover, the liquid side connector 7 is arrange | positioned above the chemical | medical agent side connector 5 of the chemical | medical agent side mounting member 2, and is connected with respect to the chemical | medical agent side connector 5 so that separation | detachment is possible.

  The drug container holder 4 has a cylindrical holder main body 40, and a holder 41 that holds the first drug container 100 and a second drug container 200 are held on the inner surface of the holder main body 40. A holding portion 42 is formed. The first drug container 100 and the second drug container 200 are each held so that the port portion 102 faces upward.

  The holder main body 40 and the holding portion 41 may be formed integrally, or may have a configuration in which another member is fixed by adhesion, fusion, or the like. Moreover, the holder main body 40 and the holding part 42 may be formed integrally, and the structure which fixed another member by adhesion | attachment, melt | fusion, etc. may be sufficient as it.

  A protrusion 401 is formed on the upper end of the outer surface of the holder body 40 to engage with a recess 501 of the connector body 50 of the drug-side connector 5 described later.

  Each of the holding portions 41 and 42 has an annular shape. The inner diameter of the holding portion 41 is smaller than the outer diameter of the bottle body 101 and the outer diameter of the port portion 102 of the first drug container 100 and is the same as the outer diameter of the neck portion 103 or slightly larger than the outer diameter of the neck portion 103. It is set large. When the first drug container 100 is attached to the drug container holder 4, the port part 102 of the first drug container 100 is inserted into the holding part 41 from below. Thereby, the holding part 41 is located between the port part 102 and the bottle body 101, that is, on the outer periphery of the neck part 103, and the first drug container 100 is held by the holding part 41.

  Similarly, the inner diameter of the holding part 42 is smaller than the outer diameter of the bottle body 101 and the outer diameter of the port part 102 of the second drug container 200 and is the same as the outer diameter of the neck part 103 or the outer diameter of the neck part 103. Is set slightly larger. When the second drug container 200 is attached to the drug container holder 4, the port part 102 of the second drug container 200 is inserted into the holding part 42 from below. Thereby, the holding part 42 is located between the port part 102 and the bottle body 101, that is, on the outer periphery of the neck part 103, and the second drug container 200 is held by the holding part 42.

  These holding portions 41 and 42 are arranged so that the holding portion 41 is located below the holding portion 42. In the illustrated configuration, the holding units 41 and 42 are respectively in a state where the first drug container 100 is held by the holding unit 41 of the drug container holder 4 and the second drug container 200 is held by the holding unit 42.

It arrange | positions so that it may be located below the bottom part of the bottle main body 101. The holding part 41 is arranged on the left side and the holding part 42 right side.

  Here, as described above, since the outer diameter of the neck portion 103 of the first drug container 100 is larger than the outer diameter of the neck portion 103 of the second drug container 200, the inner diameter of the holding portion 41 is equal to that of the holding portion 42. The inner diameter is set to be larger than the inner diameter, whereby it is possible to prevent the second drug container 200 from being held in the holding part 41 and to hold the first drug container 100 in the holding part 42. Can be prevented. Accordingly, the plug 104 of the first drug container 100 and the plug 104 of the second drug container 200 are pierced by the first drug side puncture needle 51 and the second drug side puncture needle 52, which will be described later, respectively. (Puncture), and the first liquid side puncture needle 71 and the second liquid side puncture needle 72 pierce the plug body 104 of the first liquid container 300 and the plug body 104 of the second liquid container 400, respectively ( In the operation of puncturing (hereinafter, simply referred to as “puncturing operation”), the plug 104 of the first drug container 100 and the plug 104 of the second drug container 200 are respectively connected with an inappropriate puncture needle. Puncture is prevented and puncture can be performed with an appropriate puncture needle. Therefore, the holding parts 41 and 42 constitute a second erroneous connection preventing means.

  Note that the second erroneous connection preventing means includes that at least one of the first drug container 100 and the second drug container 200 is the first drug side puncture needle 51 and the second drug side puncture needle 52. For example, only the second drug container 200 is prevented from being held by the holding portion 41, as long as it is configured to prevent puncture by the inappropriate puncture needle. In addition, it may be configured such that only the first drug container 100 is held by the holding portion 42 is prevented.

  Each of the holding portions 41 and 42 may be formed with a slit extending from one end to the other end in the vertical direction. Thus, when the first drug container 100 and the second drug container 200 are mounted on the drug container holder 4, the port portion 102 of the first drug container 100 is set in the holding portion 41 and the second portion is set in the holding portion 42. The port portion 102 of the drug container 200 can be easily inserted.

  Each of the holding portions 41 and 42 may have a shape in which a part of the annular portion (annular portion) is cut out, for example, a C shape. In this case, the same effect as that obtained when the slit is formed can be obtained.

  The drug-side connector 5 includes a cylindrical connector body 50, a first drug-side puncture needle 51 and a second drug-side puncture needle 52 that are positioned inside the connector body 50 and are fixed to the connector body 50. have.
