DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ampule bagging apparatus for packing ampules (including drug storage containers such as vials) based on an injection prescription at a hospital or the like.

[0002]

2. Description of the Related Art In recent years, large-scale hospitals have adopted an injection ordering system in which ampules dispensed from an automatic dispensing machine according to an injection prescription are collected, and these ampules are stored in a medicine bag by a bag filling device.

As the bag filling device, the present applicant supplies a medicine bag to a bag bed as shown in Japanese Patent Application No. 10-75882, and opens the medicine bag on this bed by suction and an arm. A configuration is proposed in which an ampoule is fed into a medicine bag by a conveyor which has been rushed into the bag, and the medicine bag is transferred to an input bed and paid out to a bucket.

Although this bag packing apparatus can pack an ampule securely without breaking it, it has a complicated structure and a high cost. Further, since the conveyor is inserted into the medicine bag when the ampoule is inserted, an applicable medicine bag can be used. There is a limit on the minimum size of

[0005] Further, when the injection of the ampoule collected in the medicine bag is mixed with the infusion in the infusion bottle and administered by infusion, it is necessary to manage the combination of the medicine bag and the infusion bottle for each patient. As a management form, a method is conceivable in which a bagging device is provided with a punching device for punching a medicine bag, and the medicine bag is hung on the neck portion of the infusion bottle by using an engagement hole formed thereby.

However, when this method is employed, if the ampoule is packed in the bag-filling device before the engagement hole is formed, the medicine bag may inflate, causing a problem when drilling by the punching device. If the ampule is fed in later, the ampule may jump out of the engagement hole and not be packed in a bag.

[0007]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and provides an ampule bagging apparatus having a relatively simple structure which can be applied to a small-sized medicine bag. It is another object of the present invention to provide a bag filling device in which an engagement hole to an infusion bottle can be formed reliably, and an ampule can be prevented from leaking from the engagement hole.
