Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to improvement of a medical container for containing a medical liquid such as physiological saline or a high-calorie infusion, and particularly, the liquid level of the medical liquid can be easily confirmed. A medical container is provided.

[Problems to be Solved by Conventional Techniques and Inventions] As a medical container containing a medical liquid currently on the market,
There are polypropylene bottle-shaped medical containers and bag-shaped medical containers made of polyethylene, ethylene-vinyl acetate copolymer and the like. The bag-shaped medical container had poor transparency at the time of development, and the state of the drug solution in use (when mixing and mixing multiple drug solutions, floating substances and precipitates are easily generated, so these It was necessary to infuse while paying attention to the situation), but it was pointed out that there are drawbacks such as difficulty in confirming the situation. Currently, due to the efforts of each manufacturer, commercialization of highly transparent medical containers has been promoted.

However, these transparent medical containers can easily confirm the state of the liquid medicine, but on the contrary, because the transparency is too good, the medical container and the liquid medicine are naturally exposed to sunlight, illumination light, etc. It has been pointed out that it is difficult to confirm the liquid level of the chemical liquid due to the amount of light, the visual distance, or the like. Therefore, as a result of intensive studies to solve the above problems, the inventor of the present invention can confirm the state of the chemical liquid (such as the state of formation of suspended solids and precipitates) as usual, and can easily confirm the liquid surface of the chemical liquid. We have come up with the following medical container.

[Means for Solving the Problems] As a first device, a medical container for containing a drug solution, of two inner surfaces of the container body that come into contact with the drug solution, has a height of 10 μ to 100 μ over the entire one inner surface. The present invention provides a medical container in which a protrusion is formed and the other inner surface is formed into a smooth surface, and the outer surface that does not come into contact with the container body on the side where the protrusion is formed is in contact with the chemical solution.

A second invention is a medical container for containing a drug solution, wherein one of the two inner surfaces of the container body that comes into contact with the drug solution is elevated over a range of 20 mm to 50 mm in the length direction of the container body. The present invention provides a medical container in which a protrusion having a size of 10 μ to 100 μ is formed, the other inner surface is formed into a smooth surface, and the outer surface of the container main body on the side where the protrusion is formed does not come into contact with a chemical solution and has a scale. .

[Operation] Light is diffusely reflected in a region of the container body that is not in contact with the chemical liquid,
Since light does not diffusely reflect in the region in contact with the chemical liquid, the liquid surface level can be easily confirmed and it becomes easy to perform collation with the scale.

[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 by sealing both ends of a material extruded in a tube shape. It is composed of a container body 2 in which two sheets are welded to each other to form a bag and in which a chemical solution is sealed, a mouth portion 3 made of a hard or semi-hard synthetic resin such as polyvinyl chloride, and a hanger portion 4. .

A medicinal solution 5 such as a physiological saline solution or a high calorie infusion solution is enclosed in the container body 2, and the whole inner surface of one side of the container body 2 which is in contact with the medicinal solution 5 is shown in FIG. 3) (partially enlarged view of the inner surface of the container body 2)
As shown in, the protrusion 6 having a height of 10 μ to 100 μ is formed. The projections 6 may be formed irregularly, or the projections 6a shown in FIG. 4 (a partially enlarged view of the cross section of the container body 2) and FIG. 5 (a partially enlarged view of the inner surface of the container body 2). As described above, the container body 2 may be regularly formed in a linear shape in the length direction (from the mouth portion 3 to the hanger portion 4).

Further, a scale 9 is provided on the outer surface (the back surface of the inner surface on which the projections 6 and 6a are formed) of the container body on the side where the projections 6 and 6a are formed and which does not come into contact with the chemical liquid.

By forming the projections 6 and 6a, a region not in contact with the chemical liquid looks whitish due to the diffuse reflection of light, and a region in contact with the chemical liquid looks slightly transparent because the diffuse reflection is small. In other words, when the liquid level of the chemical liquid 5 decreases, the protrusion 6
Is reflected irregularly and appears to be three-dimensionally raised. From the above, the boundary of the liquid surface can be clearly identified, and the boundary of the liquid surface fluctuates with the fluctuation of the liquid surface level, so that the liquid surface level can be easily confirmed.

The synergistic action of these and the scale 9 makes it easier to check the liquid level and the scale 9, and the remaining amount of the chemical liquid can be confirmed at a glance, so that workability is improved.

Also, like the medical container 1a shown in FIG.
In a partial region 8 of one surface which is in contact with the chemical solution 5a, the projections 6 and 6a are irregularly formed as described above or the container main body 2a over a range of a height of 10 μ to 100 μ and a width of 20 mm to 50 mm. Direction (from mouth 3a to hanger 4
The same effect can be obtained by regularly forming linearly in the (a direction).

[Effects of the Invention] As described above, the medical container of the present invention is capable of confirming (A) the state of the chemical liquid (such as the state of formation of suspended solids and precipitates) as usual, and The liquid level of the chemical liquid can be easily confirmed without being affected by the adjustment or the visual distance. (B) Due to the synergistic action of the scale (A) and the scale 9, the scale 9 can be easily compared with the liquid surface level, and the remaining amount of the chemical liquid can be confirmed at a glance, so that workability is improved.
