Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an improvement in a medical container for containing a drug solution such as a physiological saline solution or a high-calorie infusion solution, and particularly to a medical container improved so that the drug solution is not contaminated. Regarding the container.

[Problems to be Solved by Conventional Techniques and Inventions] The proximal end of a drug solution transfer tube having a connector attached to the tip is connected to the mouth of a medical container containing a drug solution, and the connector is connected to a catheter, body fluid treatment circuit, or the like. The chemical solution was transferred by connecting it to the connector attached to the chemical solution transfer tube of, but when connecting these connectors, the chemical solution comes into contact with the outside air and germs in the atmosphere are mixed and aseptic. There was a problem that could not be maintained.

Therefore, recently, a method has been implemented in which, instead of the chemical liquid transfer tube, the chemical liquid transfer tubes whose tips are sealed are connected to each other using an aseptic connecting device.

However, since the mouth of the medical container and the base end of the drug solution transfer tube are usually connected by an adhesive, a solvent, etc., these adhesives, etc. enter the drug solution and contaminate the drug solution. If it does, there is no point in aseptically connecting the drug solution transfer tube using the aseptic connection device. Therefore, the present inventor has arrived at the next inventor as a result of intensive studies.

[Means for Solving the Problems] A medical container 1 for containing a drug solution, which is composed of a container body 2 and a mouth portion 3 and has a cylindrical inner surface on a top surface of a cap 4 attached to the mouth portion 3. The present invention provides a medical container in which a pillar 5 and an outer pillar 6 are formed, and a proximal end of a drug solution transfer tube 7 is mounted in a space formed between them.

[Operation] The adhesive, solvent, etc. applied to the outer peripheral surface of the proximal end of the drug solution transfer tube 7 is transferred to the drug solution transfer tube 7 by the inner column 5.
Since the invasion into the inside or the container body 2 can be prevented, the chemical liquid sealed in the container body 2 can always be maintained in a clean state.

[Example] FIG. 1 shows a schematic view of a medical container 1 of the present invention.

The medical container 1 is made of a flexible synthetic resin such as polyvinyl chloride or ethylene-vinyl acetate copolymer, and is formed into a bag shape and has a container body 2 in which a drug solution is enclosed and a hard or semi-made container such as polyvinyl chloride. The mouth portion 3 is made of a hard synthetic resin. A cap 4 is attached to the upper portion of the mouth portion 3, and a cylindrical inner pillar 5 and an outer pillar 5 are provided on the top surface of the cap 4 as shown in FIG. 2 (enlarged sectional view of portion A in FIG. 1). 6 is formed,
In the space formed between them, the drug solution transfer tube 7
The base end of is attached. Inside the inner column 5, a liquid medicine discharge port 8 that connects the inside of the container body 2 and the inside of the liquid medicine transfer tube 7
Are formed.

As a means for mounting the chemical liquid transfer tube 7, an adhesive, a solvent or the like is applied to the outer peripheral surface of the chemical liquid transfer tube 7 to firmly connect it to the inner surface of the outer column 6, while the other end of the chemical liquid transfer tube 7 is attached. The inner peripheral surface is loosely fitted to the outer peripheral surface of the inner column 5. The tip of the drug solution transfer tube 7 is sealed (9 in FIG. 1 is a seal portion), and sterility is maintained so that the drug solution enclosed in the container body 2 does not come into contact with the outside air.

As described above, since the adhesive, solvent, etc. applied to the outer peripheral surface of the proximal end of the drug solution transfer tube 7 can be prevented from entering the drug solution transfer tube 7 or the container body 2 by the inner column 5, The chemical liquid sealed in the container body 2 can always be kept in a clean state.

[Advantages of the Invention] As described above, in the present invention, the chemical liquid enclosed in the container body 2 can be always maintained in a clean state and transferred without being contaminated by the adhesive or the like.
