BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid medicine injection container used as an enema container or the like.

[0002]

2. Description of the Related Art As a medical liquid injection container used for an enema container or the like, a container body made of a synthetic resin that can be deformed by pressing, and a connection tube attached to the mouth of the container body and at the center of the top. It consists of a synthetic resin cap member that is integral with the tube, and a tube that is watertightly inserted into the connection tube and that includes a nozzle member with a nozzle cap fitted at the tip. An enema device with a check valve that is installed and inserted movably is known (Shokai Sho 62-
157545).

In the conventional liquid medicine injection container,
Most of them have a structure in which a cap is fitted to the chemical injection port at the tip of the tube like the above-mentioned chemical injection container, and the cap is removed at the time of use.

[0004]

As described above, in the conventional liquid medicine injecting container, the liquid medicine injecting port is configured to be fitted with the cap, so that the cap may be damaged by some shock during storage or transportation before use. There was a problem that it came off and the chemical liquid leaked. In addition, it is troublesome to dispose of the removed cap during use, or to temporarily leave it in a predetermined place for disposal.

In view of the above points, the present invention has an object to provide a chemical liquid injection container in which the cap does not come off and the chemical liquid does not leak, and the processing of the removed cap does not require any labor.

[Means for Solving the Problems] A drug solution injection container of the present invention comprises a drug solution container body made of a flexible material, and a drug solution injection port provided at a tip end connected to a mouth part of the drug solution container body. It consists of a tube, and a check valve is enclosed in the mouth of the chemical solution container body.A partition wall is formed on the tube to form a compartment between the tube tip and the partition wall. The needle-shaped body is characterized in that the sharpened portion is enclosed with the sharpened wall facing the partition wall.

In this drug solution injecting container, a drug solution container body made of a flexible material is filled with a drug solution such as an enema solution, and when the drug solution is deformed by being pressed, the drug solution passes through the mouth portion of the tube tip. It is designed to be pushed out from the chemical supply port. Therefore, as the flexible material, a material such as a soft thermoplastic resin that does not dissolve in a chemical solution, for example, a polyolefin resin such as polyethylene or ethylene-vinyl acetate copolymer, a soft vinyl chloride resin, or the like is used.

[0008] Incidentally, the chemical liquid injection container made of an olefin resin has a problem that the strength of the joint portion of the container is not sufficient, so that the content liquid easily leaks, and it is difficult to guarantee the quality as a pharmaceutical product. In an ordinary liquid medicine injection container made of a soft vinyl chloride resin to which a plasticizer is added, the liquid plasticizer may elute and adversely affect the liquid medicine such as glycerin enema. Therefore, it is said that it is made from a so-called non-plastic soft vinyl chloride resin containing ethylene / carbon monoxide / (meth) acrylic ester copolymer without adding such a plasticizer. It is particularly suitable for use because it does not elute plasticizers, has moderate flexibility, is transparent, and allows the contents to be observed.

[0009]

In use, first, the tip of the tube is squeezed with a finger from the position where the needle-shaped body is present. By the crushing of the tube wall, the needle-shaped body moves to the container body side and the partition wall is pierced, so that the drug solution in the container body can flow out from the drug solution inlet.

Then, by inserting the tube into the body and pressing the container body to deform it, the drug solution flows into the tube through the mouth and is injected into the body through the drug solution supply port. The chemical liquid is prevented from flowing back to the check valve enclosed in the mouth.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the chemical liquid injection container of the present invention will be further described with reference to the embodiments of the drawings. FIG. 1 is a vertical cross-sectional view of a drug solution injecting container according to the present invention, in which 1 is a container body, 11 is an opening of the container body 1, 2 is a tube, 3 is a check valve, and 4 is a needle-shaped body.

The container body 1 and the mouth 11 are made of vinyl chloride.
100 parts by weight of ethylene copolymer (average degree of polymerization 1300, ethylene content 4% by weight), ethylene / carbon monoxide /
n-Butyl acrylate copolymer (carbon monoxide content 1
0% by weight, n-butyl acrylate content 30% by weight)
The transparent resin composition containing 160 parts by weight is integrally molded by a blow molding method.

The mouth portion 11 has a cylindrical shape, and the mouth portion 11
A check valve 3 made of a sphere is enclosed in the container, and a connector 5 for connecting the tube 2 is fixed to the opening. The inner portion of the tubular mouth portion 11 has a small diameter, and the check valve 3 does not enter the container body 1 but abuts the small diameter portion to block the mouth portion 11 and prevent backflow. Even if the check valve 3 moves to the connection tool 5 side, the chemical solution flows to the tube 2 side without blocking the passage.

The connector 5 is made of a hard thermoplastic resin such as a hard vinyl chloride resin, the mouth 11 is fixed to one end by high frequency fusion, and the tube 2 is high frequency fusion at the other end. It is fixed and connected by the wearing method.

As shown in detail in FIG. 2, the tip of the tube 2 is sealed at the front end and a chemical injection port 21 is provided in the vicinity thereof, and a partition wall 22 is provided on the container body 1 side from the chemical injection port 21. By being provided, a compartment 23 is formed between the tip of the tube 2 and the partition wall.

The acicular bodies 4 are enclosed in the compartments 23. The needle-like body 4 is a tubular body in which the large diameter portion of the tapered portion having a sharp tip is slightly smaller than the inner diameter of the tube 2, and a hole 41 is formed in the tapered portion, and the sharp portion is partitioned. Wall 22
Is directed to. When the needle-like body 4 is moved by crushing the distal end portion of the tube 2, the sharp end thereof pierces the partition wall 22 and the medicinal solution can flow out, and the needle-like body 4 is made into the tubular body as described above. As a result, the drug solution is needle-shaped 4
Since it reaches the chemical liquid inlet 21 through the hole 41, it is preferable because it also has a backflow preventing effect although it is not perfect.

[0017]

As described above, the liquid medicine injection container of the present invention does not require a cap to be fitted to the liquid medicine injection port, unlike the conventional one, and there is no fear that the liquid cap will come off and the liquid medicine will leak. In addition, the removal of the cap does not require any processing, and the chemical liquid injection operation becomes simple.
