[0002]
[Prior art]
For example, a drug solution for injection is provided by a pharmaceutical company in a state of being dispensed into glass ampules or plastic containers for each unit volume. At present, pharmaceutical companies take a lot of man-hours for this dispensing process.
On the other hand, it is difficult to provide an oral drug solution from a pharmaceutical company in a state in which a single dose is dependent on the age, and the drug solution is usually dispensed in small containers in advance. The drug is prescribed by mixing several days. The plastic bottle is provided with a scale, and the patient takes a single dose specified by a doctor, a pharmacist, etc. while taking the scale and taking the medicine.
In addition, a certain amount of a liquid such as a parenterally administered liquid, for example, a disinfectant used during a procedure such as surgery, or a liquid such as a mouthwash not used but used for disinfection is frequently used. The situation is similar when used for
[0003]
[Problems to be solved by the invention]
However, for example, in the case of a liquid medicine for oral use, since the method involving dispensing as described above is a measurable amount, it is difficult to accurately dispense and take a single amount of a prescribed medicine. . In addition, when a drug solution is formulated with a granule preparation such as an antibiotic, it often precipitates at the bottom of the plastic bottle. However, there has been a problem that the amount of the granule preparation to be taken per dose is extremely small or, conversely, extremely large. This is not preferable from the viewpoint of the therapeutic effect and the risk of side effects.
Furthermore, there is also a problem in medicine management that a chemical solution put in a plastic bottle is easily spilled, and there may be contamination of various bacteria at the stage of being stored by an individual patient.
Therefore, it is conceivable to inject a single dose according to various conditions such as the age of the patient into one small container in advance and prescribe it. However, it is very troublesome for the dispenser to inject one small container at a time. It is.

[0006]
It should be noted that the liquid according to the present invention requires a medical fluid such as a drug solution or a body fluid, which requires an approximately accurate usage volume for oral administration or parenteral administration, and the amount varies depending on the target patient. It handles liquids that require a dispensing operation, such as the need for dispensing from an undiluted solution, such as the need for dispensing, or the need for a small amount suitable for the situation in which it is used. Specifically, it is an injection drug solution, a drug solution to be taken, a drug solution for disinfection, or a biological fluid such as serum, which prevents not only accurate dispensing but also the use of medical fluids, especially bacteria, etc. In addition, there is a need for a liquid container that can be dispensed relatively easily in a single-use amount in a clean form in which consideration is given particularly to preventing the propagation of various bacteria.
In the following embodiments of the present invention, explanations will be given by use intended for the embodiment of the medicated liquid and disinfectant, but the present invention is similarly applied to the above-mentioned injectable liquid and biological fluid.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described with reference to the drawings.
The liquid container connecting body 1 shown in FIG. 1 has a dispensing inlet 11 opened at one end and an outlet 12 opened at the other end. Between them, three liquid storage portions 131, 132, 133 for storing a chemical solution are connected in a rosary shape via tube-shaped connection portions 141, 142.
[0008]
The liquid storage unit connected body 1 is welded by injection molding, blow molding, vacuum molding or other sheet-like or film-like thermoplastic synthetic resin material made entirely of a thermoplastic synthetic resin material such as polyolefin or polyester. It is formed integrally by secondary processing such as processing, and the inside of each of the liquid storage portions 131, 132, and 133 is in a communicating state.
The type of the synthetic resin material is not particularly limited as long as it can be subjected to the above-described injection molding, blow molding, vacuum molding, and secondary processing using a sheet-like or film-like thermoplastic synthetic resin material. The material used is a multi-layer with a functional material to prevent the permeation of a specific component such as ventilation, moisture, etc. to prevent evaporation of the liquid, or a material that has been treated to prevent ultraviolet rays, etc. to prevent deterioration. In general, a light-transmissive colored material is preferably used so that the contents can be seen.
[0009]
The injection port 11 for dispensing is formed in a tube shape, one end of which is opened so that a nozzle (not shown) of a syringe can be inserted, and the other end is connected to the liquid storage portion 131, as described later. A drug solution or the like stored in a syringe is injected from the injection port 11 and stored in a plurality of liquid storage units. At this time, the amount of liquid to be injected is determined according to the number of connected liquid storage units. For example, in the case of the liquid storage unit connection body 1 in which three liquid storage units (131, 132, and 133) are connected. Is used three times as much as liquid. After the liquid is injected, the injection port 11 is closed by being pressed or welded with a clamp, a heat sealer or the like as shown in FIG. 2 (closing portion 111 in FIG. 2).
[0010]
The liquid storage portion 131 and the liquid storage portion 132 are connected by a tube-shaped connection portion 141, and the liquid storage portion 132 and the liquid storage portion 133 are similarly connected by a tube-shaped connection portion 142. After the liquid is evenly stored in the plurality of liquid storage portions 131, 132, and 133, the connection portions 141 and 142 are press-bonded at two locations separated by a predetermined distance by a heat sealer, a clamp, or the like, as shown in FIG. It is closed by welding. Then, it is cut at a portion between the two closed portions of the closing portions 1411 and 1421 as shown in FIG. 2 (portions separated from the liquid storing portion), and as shown in FIG. , A liquid container 152 having a liquid container 132, and a liquid container 153 having a liquid container 133. Then, as shown in FIGS. 3 and 4, in this example, when the connecting portions 141 and 142 are used as separated liquid containers (when taking the chemical solution in FIG. 4), the drainage ports 1511 (1521) are used. ).
Here, it is preferable that the closing portions 1411 and 1421 are formed at positions where the lengths of the drainage ports 1511 and 1521 can be ensured to be relatively long. In this case, it is easy to inject into the oral cavity. Notches 1412 and 1422 are preferably formed as opening means for opening the closed drain ports 1511 and 1521 when used.
[0011]
The outlet 12 is formed in a tubular shape like the inlet 11, and one end is opened and the other end is connected to the liquid container 133. The reason why the discharge port 12 is opened is that, as described later, the air is discharged from this portion, and the liquid is uniformly stored in each of the liquid storage portions 131, 132, and 133. As shown in FIG. 2, the outlet 12 is finally closed by being pressed or welded with a heat sealer, a clamp, or the like, like the inlet 11 and the connecting portions 141 and 142 (closing portion 121). . Further, like the connecting portions 141 and 142, when used as a separated liquid container (when taking a chemical solution or the like), it functions as a drain port 1531, and the closed drain port 1531 It is preferable that a notch 122 is formed as an opening means for unsealing.
[0012]
The length of the above-mentioned drainage ports (1511, 1521, etc.) and the form of the tube-shaped connecting portion, which have been described as being preferably formed relatively long from the usage form for taking the medicinal liquid, are described in the liquid storage portion. It is sufficient that the liquid is appropriately formed in a shape suitable for the type and use form of the liquid stored in 131, 132, and 133. [For example, in the case of an injection drug solution, it is formed in a wide mouth shape so that an injection needle can be easily inserted, or a luer shape that can be luer-coupled to the tip shape of a syringe is used. ]
[0013]
Hereinafter, the steps of the liquid dispensing operation to the liquid container connecting body 1 shown in FIG. 1 will be described.

(2) After injecting the entire amount of the liquid in the liquid container, the liquid storage unit connected body 1 (the liquid storage units 131, 132, and 133) is pressed, and substantially all of the internal air is discharged from the upper discharge port 12.
(3) Then, the inlet 11 and the outlet 12 are closed by pressing or welding with a clamp, a heat sealer or the like.
(4) After that, the liquid storage unit connected body 1 is leveled, and the liquid is transferred so as to be uniformly stored in the liquid storage units 131, 132, and 133, and the connection units 141 and 142 are separated by a predetermined distance. A closed portion is formed by pressing or welding two places with a clamp, a heat sealer, or the like.
(5) Further, by cutting between each two closed portions of the closing portions 1411, 1421, the individual liquid containers 151, 152, 153 accommodating a single use amount can be obtained.
[0014]
By the way, in the example of the above-described embodiment, the work of discharging the inside air after injecting a predetermined amount of liquid into the liquid container connecting body 1 was performed. It is also possible to dilute the equal liquid and fill it. According to this method, it is sufficient to inject a predetermined amount of liquid diluted in advance into the liquid storage unit connected body 1 as long as the liquid storage unit connected body 1 is filled, so that it is not necessary to adjust the amount at the time of injection. In addition, it is possible to eliminate the trouble of transporting the liquid so as to be uniformly stored in each of the liquid storage sections, thereby improving the efficiency of the injection operation.
[0015]
Here, the step of injecting the liquid into the liquid container connecting body 1 and then discharging substantially all of the air from the inside has been described. However, by intentionally enclosing an appropriate amount of residual air in each liquid container, Alternatively, a method of obtaining a liquid container linked body in which a predetermined amount of content liquid and a predetermined amount of air are stored in each liquid container may be adopted, and the method will be described later.
