Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a carbohydrate infusion, an electrolyte infusion, a plasma expander,
Intravenous infusions such as osmotic diuretics, amino acid infusions, fat emulsions, and high-calorie infusions, and enteral high-calorie nutritional products such as enteral nutrition, high protein nutrition, component nutrition, and liquid food. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called natural dropping type plastic blow bag, which is a flexible plastic container into which a chemical solution is filled and which dispenses contents by deforming a body.

[Prior Art] In recent years, chemical containers have rapidly become plastic because of their advantages such as being not broken even when dropped and being lightweight. In particular, a spontaneous dropping type in which administration is performed by deforming the body using the flexibility of a plastic material is frequently used. This is because, in the case of spontaneous dropping, administration can be performed without supplying air into the container, and therefore, there is a sanitary advantage that there is no fear of invasion of various bacteria into the container. As this kind of plastic container for chemicals,
Japanese Patent Application Publication (hereinafter referred to as “conventional publication”). In this method, a container is formed by sealing the periphery of a thin plastic film, and a chemical solution inside the container is formed by welding a plug body to a body wall of a body part. ) To the outside.

[Problems to be Solved by the Invention] However, in the container disclosed in the conventional publication, since the body walls forming the body are adjacent to each other, an injection needle is required when the internal liquid medicine is administered to the patient from the mouth. Attempting to penetrate the plug that seals the mouth with an injection needle at the, would cause an accident to break through the body wall of the opponent partner, and it was extremely careful when administering the drug solution .

Thus, the present invention provides a drug solution container that does not break through the body wall of the opponent with the injection needle when the stopper is penetrated with the injection needle, and provides a stopper with the injection needle at the time of administration. An object of the present invention is to provide a container in which the work of penetrating the body can be performed extremely easily, and in which this kind of work that has caused a great deal of strain on nurses can be performed very easily.

Means for Solving the Problems In order to achieve the above object, the present invention has the following configuration. In a blow-molded chemical liquid plastic blow bag having a flat cross section, a hanging portion at the upper end edge of the body portion, and a stopper body with a rubber stopper inside the lower body wall, the opposed lower body wall is formed by A space is formed between the lower body walls in a natural state in which a chemical solution does not enter by expanding at a sharp angle from the lower edge, and a plug is welded to the outer surface of the lower body wall that is expanded at the acute angle to form a plug inside the body. A chemical liquid characterized in that a rubber stopper provided inside a stopper is separated from a body wall by a body wall, and a distal end portion of an injection needle that penetrates the rubber stopper of the stopper escapes to the body wall in the body. For plastic blow bag. It is what it was.

[Action] In the chemical solution blow bag of the present invention, the lower end body wall opposed to the lower body edge is formed to expand at an acute angle from the lower end edge, and the stopper is welded to the lower end body wall, so that the injection needle passes through the stopper. When the needle is inserted, the angle of the needle is expanded in the direction in which it escapes from the body wall of the opponent. When filling is made, the angle between the opposed lower body walls is further increased, and the above danger can be almost eliminated.

[Embodiment] FIGS. 1 to 4 show an infusion plastic blow bag according to an embodiment of the chemical solution plastic blow bag of the present invention.
A description will be given based on the drawings.

FIG. 1 and FIG. 2 show a front view and a side view of a plastic blow bag for infusion. In the drawing, reference numeral 1 denotes a plastic blow bag for infusion, and a body 2 and an upper edge 3 of the body 2
Hanging part 4 and lower end body wall 5 of body part 2 integrally connected to
The plug 6 is formed of a plug. The body 2 has a flat cross-sectional shape, and has a generally elongated shape in the vertical direction. Therefore, the shape of the body 2 shows a bag shape, and the natural dropping property is good. Hanging part 4
Is thicker than the body portion 2 and has a strength enough to hold the infusion plastic blow bag 1 in a state where the infusion is filled in the infusion plastic blow bag 1. The plug 6 welded to the lower end wall 5 of the body 2 is integrally welded to the outside of one of the lower end walls 5a, 5b of the body 2 facing each other. The lower end body walls 5a and 5b facing each other are expanded at an acute angle from the lower end edge 7 of the body portion 2. The angle α is about 50 ° in this embodiment, but according to the result of the experiment, a good result is obtained if the angle is 30 ° to 60 °. If the distance is less than 30 mm, an accident that breaks through the opposing wall when inserting the needle is likely to occur.
If it exceeds ゜, the dropping property will be impaired during spontaneous dropping. Plug 6
As shown in FIG. 3, the plug body 8 is formed of a plug main body 8 and a rubber plug 9 housed therein, and the plug main body 8 has a flange portion 8a extending outward. The lower end body wall 5a of the body 2 is welded. Reference numeral 10 denotes a pull ring. The pull ring 10 is integrally formed with the top plate 8b of the plug body 8, and a score 11 portion formed of a thin portion is formed on the top plate 8b, and the pull ring 10 is pulled. Are removed from the score 11 to expose the rubber plug 9. In addition, the rubber stopper 9 which has a problem of hygiene when it comes into direct contact with the infusion is sanitary because it is isolated from the infusion by the lower end wall 5a of the body 2. 12 is a filling port for filling the infusion. The plastic blow bag for infusion is filled with the suspending portion 4 with the filling port 12 facing up.
By filling infusion 12 and sealing the filling port 12, a plastic blow bag for infusion can be obtained. At the time of use, pulling the pull ring 10 exposes the rubber stopper 9 and the lower end body wall 5a, inserts the injection needle 13 into the stopper 6, penetrates the rubber stopper 9 and holds it with the hanging part 4, It is administered to the patient via a rubber tube (not shown) communicating with 13.

At this time, the distal end 13a of the injection needle 13 is opposed to the lower end wall 5b.
As a result, there is no occurrence of an accident that the distal end 13a of the injection needle 13 penetrates the opposed lower body wall 5b and leaks the infusion to the outside.

[Effects of the Invention] In the plastic blow bag for chemicals of the present invention, the opposed lower end body wall is expanded at an acute angle from the lower edge to form a gap between the lower end body walls in a natural state where no chemical liquid is contained, and Since the plug is welded to the outer surface of the lower end trunk wall that has been expanded to an acute angle,
The rubber plug of the stopper is completely sanitized from the inside of the torso by the torso wall, and the tip of the rubber stopper of the stopper escapes to the torso wall in the torso when the injection needle passes through the torso. Therefore, even when the amount of the chemical solution is small, it is possible to eliminate breakage of the trunk portion during needle insertion.
