BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for a container for a tube-administering agent such as an enteral nutrient and a tube (catheter) for feeding the tube-administering agent into a patient's body through a nasal passage or the like.

[0002]

2. Description of the Related Art Conventionally, many enteral nutritional preparations such as enteral nutrients are prepared by dissolving powder in a bag with water or slightly warm water, or in the form of cans prepared by dissolving in a fluid state. At the time of administration, fluid nutrients and the like dissolved in advance were transferred to a dedicated container and administered to the patient. As shown in FIGS. 24 and 25, a dedicated container 100 used in this case is a bag-shaped body welded and sealed with a PVC or polyolefin-based synthetic resin film, or as shown in FIGS. 26 and 27, It was a cylindrical injection molded of polypropylene or the like. In each case, the container 100 is composed of a main container 101 and a lid 102, and the tube administration agent can be exchanged (transferred). The container 100 is used by being suspended from a stand (not shown) or the like by the suspension unit 103. . The tube administration agent in the main body container 101 flows down the tube 105 via the nozzle portion 104 and is administered to the intestine or the like of a living body. In the figure, reference numeral 106 denotes a drip tube for confirming the dripping state of the solution, and 107 denotes a roll clamp for adjusting the flow rate.

[0003]

However, in the above-mentioned conventional transfer exclusive container method, the main container and the lid are washed (sterilized) each time, and the tube 105 is connected to the nozzle 104 at the lower end of the container. The detachment was inconvenient. The tube of the tube 105 that is attached to and detached from the nozzle unit 104 is made of rubber, and the nozzle unit 104 has a non-slip convex portion, so that there is no fear that the tube will come off even if a slight force is applied,
It couldn't be said that there was nothing, and the attachment and detachment was troublesome. In addition, it was not possible to say that the mixing of room germs at the time of transferring the powder from the can to the dedicated container was troublesome, and was not a good form. For this reason, in the case of enteral nutrition, such as tube feeding, the tube is easily and steadily transferred from a pre-dissolved fluid nutrient container to another container without transfer. It has been desired to develop a container that can be joined and a joining method thereof.

The present invention has been made to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide a method of dissolving a fluid, which has been dissolved in advance, by tube administration of an administration agent such as an enteral nutritional supplement. An object of the present invention is to provide a container connector that can join a container to a tube for tube administration in order to easily and steadily administer the container without transferring the agent from a container containing the agent to another container. .

In response to this object, a connector for a tube administration agent of the present invention comprises a spout member which is liquid-tightly joined to the tube administration container, and a connection member which is detachably connected to the spout member. A spout member having a liquid passage formed in a central axis direction and a thin film closing the passage, wherein the connection member can penetrate the thin film.
