Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drug solution injecting container used for an enema container or the like.

[0002]

[Prior art]

 As a medical fluid injection container used for enema containers, etc., a synthetic resin container body that can be deformed by pressing, and a synthetic tube that is attached to the mouth of the container body and has a connecting tube integrally in the center of the top It consists of a resin cap member and a tube equipped with a nozzle member that is water-tightly fitted and inserted into the above-mentioned connecting cylinder and has a nozzle cap fitted at the tip, and a check valve is moved inside this tube with a gap around it. An enema with a check valve that is freely inserted is known (Japanese Utility Model Laid-Open No. 62-157545).

[0003] Most of the conventional liquid medicine injection containers have a structure in which a cap is fitted to the liquid medicine injection port at the tip of the tube like the liquid medicine injection container described above. I was taking it off.

[0004]

[Problems to be solved by the device]

 As described above, the conventional liquid medicine injection container has a structure in which the liquid medicine injection port is fitted with a cap.Therefore, during storage or transportation before use, the cap may come off due to some shock and the liquid chemical may leak. There was a problem. In addition, when using the cap, it was troublesome to dispose of the removed cap or to temporarily put it in a predetermined place for disposal.

In view of the above points, an object of the present invention is to provide a chemical liquid injection container in which the cap does not come off and the chemical liquid does not leak, and the cap does not have to be processed.

[0006]

[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 the tip connected to the mouth part of the drug solution container body. It consists of a tube and the mouth of the drug solution container body is sealed with a film-like material.A check valve is enclosed in the tube, and a connector is watertightly inserted into one end of the tube and the other end of the connector is attached. The needle-shaped body is characterized in that it is inserted with its sharpened portion facing outward.

In this drug solution injecting container, a drug solution container body made of a flexible material encloses 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 extruded from the chemical injection 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 solution injection container made of a polyolefin 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. However, in a liquid medicine injection container made of an ordinary soft vinyl chloride resin to which a liquid plasticizer is added, the liquid plasticizer may be eluted and adversely affect the liquid medicine such as glycerin enema. Therefore, it is made of a so-called non-plastic soft vinyl chloride resin containing ethylene / carbon monoxide / (meth) acrylic ester copolymer without adding such a plasticizer. In particular, since the plasticizer and the like do not elute, the resin has appropriate flexibility, and the content can be observed transparently, it is particularly preferably used.

[0009]

[Action]

 In use, first, the needle-shaped body fitted into the connector is inserted into the film-shaped material that seals the mouth of the drug solution container body. By the penetration of the needle-shaped body, 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 from the drug solution supply port. The check valve enclosed in the tube prevents the backflow of the drug solution or the like.

[0011]

【Example】

 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 of 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 film-like object, 4 is a connecting tool, and 5 is a needle The body, 6 is a check valve.

The container body 1 and the mouth 11 are composed of 100 parts by weight of a vinyl chloride / ethylene copolymer (average degree of polymerization 1300, ethylene content: 4% by weight) and ethylene / carbon monoxide / n-butyl acrylate copolymer A transparent resin composition containing 160 parts by weight of a coalescence (carbon monoxide content of 10% by weight, n-butyl acrylate content of 30% by weight) is molded into a single body by a blow molding method.

The mouth portion 11 has a tubular shape, and a flanged guide tube 7 having the film-like material 3 fused thereto is fixed to the flange surface.

The tip of the tube 2 is closed at the beginning and is closed, and two drug solution inlets 21 facing each other are provided in the vicinity thereof, and a check valve 6 made of a sphere is enclosed inside. There is.

The connecting tool 4 is made of a hard thermoplastic resin such as a hard vinyl chloride resin, and one end thereof is fixed to the open end of the tube 2 by a high frequency fusion method or an adhesive agent so as to be watertight. The needle-shaped body 5 is inserted into the other end with its sharpened portion facing outward and fixed by a high-frequency fusion method or an adhesive.

The needle-like body 5 is a tubular body having a sharp tip and a large-diameter portion having an outer diameter slightly smaller than the inner diameter of the tube 2, and has three strip-shaped through-holes in the large-diameter portion. 51 are formed at equal intervals, and a through hole 52 having a diameter slightly smaller than that of the check valve 6 is formed on the end surface on the large diameter side. The structure is such that it abuts against the end surface on the radial side and closes the through hole 52 to prevent backflow.

In use, as shown in FIG. 2, if the needle-shaped body 5 is inserted into the guide tube 7 through the film-shaped material 3, the mouth portion 11 and the tube 2 are passed through the needle-shaped body 5. Communication is made possible and the chemical solution can flow out. The outer diameter of the needle-shaped body 5 is substantially equal to the inner diameter of the guide cylinder 7, and if it is forcibly inserted, it will not easily come off due to friction.

[0018]

[Effect of device]

 As described above, in the liquid medicine injection container of the present invention, since the mouth of the liquid medicine container body is sealed with a film-like material, it is not necessary to fit a cap on the liquid medicine injection port unlike the conventional one, and the cap is There is no danger of the chemical liquid leaking out. In addition, the removal of the cap does not require any processing, and the chemical liquid injection operation is simple.
