Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for producing a medical drug enclosure and a flexible container used therefor. Preferably, the present invention relates to a method for producing a medical medicinal liquid encapsulated material in which an infusion supplied to a human body is enclosed in a flexible container having a spout and a flexible container therefor.
[0002]
[Prior art]
Conventionally, infusions for supplying nutrients to the human body typically have two infusions by means of separable separating means as disclosed in, for example, JP-A-7-178151 or JP-B-6-26563. A fat emulsion and an amino acid are contained in the first chamber of a container made of a flexible resin in which a single chamber is formed, a sugar and an electrolyte are contained in the second chamber, and the first chamber or the second chamber is pressed from the outside during administration. The separating means is separated to mix the liquids in both chambers. As disclosed in Japanese Patent Publication No. 5-10945, the first chamber or the second chamber is communicated with an infusion discharge port (spout port), and the outer end of the spout port is closed with a rubber stopper. The infusion solution in the container is sent from the inside of the container into the infusion tube by allowing the injection needle attached to the infusion tube to pierce the rubber stopper at the time of administration to allow the spout and the infusion tube to communicate with each other. The conventional general method of filling such a medical chemical solution into a flexible resin container is aseptically filling the chemical solution into the container from the spout with the stopper removed under an inert gas atmosphere. The outer end of the spout was closed with a rubber stopper.
[0003]
Thus, when the inside of the container is filled with the chemical solution through the spout with the stopper removed, and then the spout is closed with a rubber plug, the inside of the container is poured between the manufacturing of the container and the filling of the chemical solution. It was opened through the outlet, causing bacteria and other foreign objects to enter. In order to solve this problem, immediately after manufacturing the container, the outer end of the spout is sealed with a temporary stopper, an air hole seal, etc., and the outer end of the spout is opened immediately before the filling process, and the spout is inserted through the spout. A method of filling chemicals has been developed.
[0004]
[Problems to be solved]
According to the conventional method of filling the inside of the container with the chemical solution through the spout with the stopper removed, and then closing the outer end of the spout with the stopper, the step of sealing the spout with the plug is immediately after filling with the chemical solution. This has been a cause of complicating the mechanism of the filling machine. The stopper is generally composed of a plug body in which the outer peripheral surface of a cylindrical rubber stopper that can be pierced with an infusion needle is surrounded by a plastic resin. Fit and weld. The first object of the present invention is to eliminate the process of closing the spout with a stopper after filling the chemical solution, to eliminate the complexity of the mechanism of the filling machine, and to simplify the sealing process of the container after filling the chemical solution. .
[0005]
Another object of the present invention is that the spout is not sealed until the flexible container used for manufacturing the medical liquid filling material is filled with the chemical liquid after manufacturing, and foreign matter enters the container. It is an object of the present invention to provide a method for manufacturing a medical medicinal liquid enclosure and a container for the same. Another object of the present invention is to sterilize a flexible container for manufacturing a medical medicinal liquid enclosure so that the sterilized state can be maintained until the medicinal liquid filling step. Still another object of the present invention is to provide a sealed flexible container capable of forming a filling port by a simple process.
