Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cylindrical light-shielding cover for an infusion bottle having a band-like edge made of metal foil at both ends or one end.

Infusion injections are performed for the purpose of replenishing fluids, electrolytes, or nutrients or maintaining circulating plasma volume, but in recent years,
So-called mixed injection, in which one or more of several drugs, such as vitamins, antibiotics, or cancer drugs, is mixed into the infusion or in a side tube and then supplied for use has come to be frequently used.

Infusions are injected into a living body using an intravenous needle by suspending an infusion bottle with an infusion set set on a support, but in medical settings, infusions last from 0.5 hours to 24 hours, and sometimes over 24 hours. This process takes a long time, and the infusion bottle is usually left exposed to the light.

Therefore, when a light-labile drug is co-injected, the drug may undergo undesirable decomposition or change in composition, and as a result, a sufficient therapeutic effect cannot be obtained.

Conventionally, various methods have been used to overcome these difficulties, such as using colored infusion bottles, or - the rounded end has an inner diameter smaller than the outer diameter of the infusion bottle body, and the fixed end has a larger inner diameter. A method using a cylindrical light-shielding bag (Utility Model Publication No. 65597/1983) made of a colored synthetic resin film has been adopted.

However, the method of using a colored infusion bottle makes it difficult to visually recognize the liquid level during the infusion and the discoloration or turbidity of the liquid content when the drug is mixed in due to the coloring of the bottle.
This is not considered a desirable method.

In addition, in the method of using a light-shielding bag, the inner diameter of the circular end is smaller than the outer diameter of the body of the infusion bottle, so the mounting direction is limited. When mounting, there is a disadvantage that it is physically impossible to adopt the simple method of suspending the infusion bottle from a support and then mounting it.

In addition, in other usage configurations, i.e., when installing the product so that the circular end with the smaller inner diameter is at the bottom and completing the covering by folding the fixed end, the complete covering may be obstructed by fishing gear etc. when folding. Even if a certain degree of covering is achieved, the synthetic resin film that is the material of the light-shielding bag has a high elasticity, so the covering may be damaged by slight external force during operation.
As a result, there is a drawback in that it is not possible to sufficiently block upward light, which is a particular problem in the medical field.

The inventors of the present invention conducted research in light of these circumstances, and found that the cylindrical body is a cylindrical body made of a colored transparent or translucent synthetic resin film that has an inner diameter considerably larger than the outer diameter of the infusion bottle body. A light-shielding cover for an infusion bottle has a shape that has a band-shaped edge made of metal foil with the same inner diameter on the circumferential end or the inner end of the infusion bottle, which allows good observation of the liquid inside and is extremely simple to operate. We came up with the present invention after finding out that it is possible to attach the infusion bottle after suspension and to almost completely cover the infusion bottle.

Embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows Example 1, and FIG. 2 shows Example 2.

In both figures, 1 indicates a cylindrical body made of a colored transparent or translucent synthetic resin film having an inner diameter considerably larger than the outer diameter of the infusion bottle body, and 2 indicates a metal foil having the same inner diameter as the cylindrical body 1. 3 indicates the cylindrical band edge consisting of the cylindrical body 1
4 indicates an open end, and 4 indicates an open end.

As the cylindrical body 1, a seamless cylindrical film or a cylindrical film with both sides or one side attached and sealed to form a bottom can be used.

The height of the cylinder is 1 to 3 times the height of the infusion bottle, preferably 1
Set to about 2 to 2.0 times.

By setting the height of the cylinder in this way, it is possible to sufficiently cover the infusion bottle and to minimize bending of the cylinder surface after coating, making it easy to observe the liquid level during the course of the infusion. can do.

Synthetic resin films include cellophane, polyethylene,
Films made of polypropylene, polystyrene, polyvinyl chloride, polyvinylidene chloride, or other thermoplastic synthetic resins, or composite films made of two or more of these can be used, but they have good coloring and transparency, and are compatible with metal foil. Cellophane film or cellophane composite film, which can be easily bonded, is suitable.

The coloring of synthetic resin films is done to prevent the decomposition of drugs mixed into infusions due to light, and the color type and tone should be within the range that can block light at wavelengths that are affected by the drugs mixed in. Just choose.

As the band-shaped edge 2, a seamless cylindrical bottom made of metal foil or a cylindrical bottom formed by adhesively sealing both sides or one side can be used.

The band width of the band edge is set to be 1/2 to 4/5 of the inner diameter.

Aluminum foil, silver foil, tin foil, steel foil, or processed paper thereof can be used as the metal foil, but aluminum foil or aluminum foil that has high light-shielding properties and is easy to bond with synthetic resin film and be mechanically processed. Processed paper is preferred.

The adhesive portion 3 may be welded as is, or may be compressed or welded using an appropriate adhesive to form a bottom shape.

It is preferable that the open end 4 is treated at the end to enhance the degree of tearing.

FIG. 3 shows a method of attaching the light-shielding cover according to the first embodiment of the present invention.

Since the light-shielding cover of the present invention has a cylindrical shape with a constant inner diameter, it can be attached to the infusion bottle 5 either from the bottom of the bottle or from the mouth of the bottle.

Therefore, the mounting direction is not limited compared to conventional light-shielding bags,
Moreover, it can be attached even after the infusion bottle is suspended from the support.

In the second embodiment, the same mounting as in the first embodiment is possible, except that care is taken to ensure that the strip edge 2 is on the upper side.

FIGS. 4 and 5 are diagrams showing the state of the light-shielding cover according to the first and second embodiments of the present invention after coating, respectively.

The infusion bottle is covered with the light-shielding cover of the present invention by manually pressing the band-shaped edge 2 along the fishing gear 6, the support 8, or the infusion set 7 to form a plastic body 9.

Embodiment 2 is used when blocking of downward light is not required, and the covering is carried out in the same manner as in Embodiment 1, except that the lower part is left open.

Since the band-shaped edge 2 is made of metal foil, it can be formed into a plastic body 9 that can be completely coated without being damaged by a slight external force by only a short manual pressure operation.

As mentioned above, the invented light-shielding cover can be easily installed and covered in a short period of time, and can be expected to have an almost complete light-shielding effect, so it can be said to meet the needs of busy medical staff. Can be done.

Furthermore, since the light-shielding cover of the present invention is foldable, it also has the advantage of being easy to handle, such as storage and transportation.
