Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid container for splitting and using a contained liquid, and more particularly to a liquid container suitable for splitting and using a liquid in which microbial contamination is a concern.

[0002]

2. Description of the Related Art The content of a liquid container is appropriately selected according to the amount of liquid to be stored. However, if containers having various types of storage are used, it takes a lot of time to manufacture, and the handleability during distribution and use is poor. Many general-purpose containers contain an amount that can be used multiple times, for example, because of their inconvenience. However, in the case of liquids that may be contaminated by microorganisms such as chemicals, if the liquid is used multiple times from the same outlet after opening, the residual liquid or discharged liquid in the container may be contaminated by microorganisms. , Each use is contained in a separate container. However, with multipurpose drug solutions that may be administered as a mixture with other drug solutions or may be administered alone, the amount used at one time differs greatly for each purpose. And inconvenience in production, distribution, and use as described above. In addition, since the container for storing the chemical solution needs to be approved by the Ministry of Health and Welfare, all containers having different capacities must be approved, which is complicated. For this reason, containers that contain small amounts of multipurpose chemicals contain a large amount of
It is used so that the residual liquid remaining after one use is discarded.

[0003] For example, vitamins and the like are mentioned as such multipurpose chemicals. The vitamin may be administered alone to the patient, or may be administered to the patient in a mixture with high-calorie infusions or other drug solutions. Conventionally,
High calorie infusions were mixed with multivitamin preparations before administration, but the use of excess vitamin preparations for a time was restricted by the Ministry of Health and Welfare. However, in recent years,
It has been found that acidosis is likely to occur unless vitamin C such as vitamin B1 is mixed with high-calorie infusion. At present, an amount of vitamin suitable for high-calorie infusion is mixed. High-calorie infusions are usually given postoperatively
It is administered to patients twice a day, but according to the currently used and widely used amount of vitamins, about half of the amount of vitamins contained in the container is transferred by syringe and mixed with a high-calorie infusion. It is also used by mixing the residual fluid with an infusion to be administered next time. Even when divided and used in this way, the entire amount of the prescribed amount of vitamin preparation contained in the container is administered. However,
In the divisional use of currently marketed chemicals, the operation is complicated, there is a high possibility of contamination by microorganisms, and furthermore, since the remaining amount differs for each container after the first use, the container must be used at the time of the second mixing. If mixed, a medical error such as the inability to administer a predetermined amount in two doses is likely to occur. In recent years, in medical containers, systems for minimizing medical errors have advanced, and technologies such as so-called double bags have been established as systems to prevent medical errors in mixing high-calorie infusions. A system to prevent medical mistakes when mixing with an infusion has not yet been established.

Wherein the discharge unit for discharging the liquid in at least one of the storage units is located at a position substantially separated from a communication path formed between the storage unit and an adjacent storage unit by a predetermined height or more. It is characterized by being arranged.

According to the present invention, first, since the plurality of storage sections partitioned by the partition section communicate with each other through the communication path, if the storage chamber is filled with the liquid at the time of manufacture, a plurality of storage sections are provided via the communication path. Since the liquid can be stored in the storage section of the liquid crystal and the number of times of filling can be reduced, the production is easy. In addition, since the communication path is arranged at a position separated from the discharge unit by a predetermined height or more, a liquid having a volume corresponding to the predetermined height can be stored in each storage unit. The liquid can be stored, and if the liquid in the storage section is discharged from a discharge section for discharging the liquid in the storage section, only the liquid stored in the storage section is discharged, and another storage section is discharged. The remaining liquid can be left in the container as a residual liquid, and the residual liquid can be used for the next and subsequent uses. Therefore, the liquid stored in the container can be easily divided and used without exposing the liquid to the outside air.

Further, in the present invention, by providing a plurality of discharge units according to the storage units, it is possible to use another discharge unit for each storage unit, and to maintain unused discharge units in a sterile state. Therefore, even in the case where another member is connected to the discharge unit and discharged, the microorganisms attached to the outer periphery can be brought into contact with the liquid in the accommodation chamber or the liquid to be discharged like the discharge unit used once. In addition, microbial contamination in divided use can be prevented. Further, in the present invention, if the communication path is disposed at a position substantially the same as the position of the liquid surface of the liquid stored in the storage section in the use state, the communication path is partitioned by the partition section below the communication path. By setting the capacity of each storage chamber in advance, it is possible to discharge a predetermined amount of liquid without performing any weighing operation by simply discharging it from the discharge unit without using any liquid level adjustment at the time of use And it is easier to divide and use. Further, in the present invention, when a plurality of partition portions are provided, if the communication passage formed in each partition portion is provided on the same end side of the container, the liquid is filled from the communication passage side when filling the storage chamber. Thereby, the liquid can be efficiently stored in all the storage chambers.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1A is a front view of a liquid container according to this embodiment, and FIG. 1B is a side view. In the figure, reference numeral 1 denotes a liquid container of this embodiment, which is formed of a resin blow-molded product, and contains two usages of a chemical liquid as a liquid. A partition wall 5 that can prevent the flow of liquid is provided in the storage chamber 3 so as to extend in the vertical direction in the use state, and a communication path 4 that allows the flow of the liquid upward from the tip of the partition part 5 in the use state. Are formed. The storage portions 7a and 7b are partitioned by the partition portion 5, and the adjacent storage portions 7a and 7b are communicated by the communication passage 4. The material of the container wall of the liquid container 1 has such transparency that the position of the liquid surface of the liquid can be confirmed from the outside. The storage unit 7
A scale 8 for checking the position of the liquid level of the stored liquid is provided on the container wall b. Discharge portions 9a and 9b are provided on both upper and lower sides of the liquid container 1 in the use state, and are sealed with a stopper made of an elastic member such as rubber. This plug can be opened by penetrating a communication needle (not shown) through the through hole of the communication needle, and can be closed by extracting the communication needle.

Hanging holes 11a and 11b for attaching to hanging hooks (not shown) are provided at positions different from the above. The discharge portion 9b is disposed below the liquid container 1 when the suspension is performed using the suspension hole 11a, and the discharge portion 9a is disposed below the liquid container 1 when the suspension is performed using the suspension hole 11b. The discharge sections 9a and 9b of the sections 7a and 7b are configured to be disposed at the lower ends in the use state, respectively. Here, "disposing the discharge unit at the lower end in the use state" means that when the liquid in one storage unit 7a, 7b is discharged by gravity, all the liquids that can be discharged from the discharge units 9a, 9b can be discharged. That is. The partition 5 is closed on the discharge section 9b side of the storage section 7b for discharging the liquid so as to prevent the flow of the liquid between the storage section 7a and the adjacent storage section 7a. Further, the position of the tip 5a of the partition 5, that is, the position of the communication part 4 is higher than the predetermined height in the use state from the discharge part 9b, and the storage part 7b stores the amount of one use of the liquid. The height is substantially the same as or higher than the position S of the liquid surface formed when the liquid is formed.

The liquid container 1 having such a structure can be manufactured by a usual method using a resin material. However, in order to store the liquid in each of the storage portions 7a and 7b, one discharge of the liquid container 1 is required. This can be performed by filling the liquid from the discharge portion 9a on the side where the communication passage 4 is provided, preferably on the side where the communication passage 4 is provided. Since the inside of the storage chamber 3 is communicated by the communication path 4, the liquid can be stored in the plurality of storage portions 7a and 7b by filling from one discharge portion, and the production is easy. In the production of this liquid container, in the case of a liquid, such as a chemical liquid, which may cause microbial contamination, it is possible to perform aseptic filling when storing the liquid in the storage chamber 3 or to perform sterilization after storing the liquid. it can.

Next, how to use such a liquid container 1 will be described. Here, an example is used in which a multivitamin preparation is contained as a drug solution, and is mixed with a high-calorie infusion solution and administered to a postoperative patient twice a day. Storage chamber 3 of liquid container 1
Contains one day's multivitamin preparation and is used twice. First, the amount of liquid stored in one storage unit 7b is adjusted to the amount of one use. At this time, by tilting the liquid container 1 to the left and right,
The amount of liquid in the storage part 7b can be adjusted by flowing the liquids a and 7b using the communication path 4. At this time, by checking the position of the liquid surface using the scale 8, it is possible to easily and accurately adjust the liquid amount in the storage section 7b. After adjusting the amount of liquid in the reservoir 7b, the suspension holes 11
a, the liquid container 1 is hung on a hook (not shown),
The discharge unit 9b is communicated with a high-calorie infusion bag as a container for storing another chemical solution using a communication tool including a communication needle or the like. As a result, the liquid for one use can be discharged from the discharge part 9b by gravity, and the multivitamin preparation can be aseptically mixed into the bag for the infusion.
At this time, the liquid stored in the storage section 7a is
Remains in Next, to perform the second administration,
The liquid container 1 is suspended using the suspension holes 11b in a state where the liquid container 1 is inverted, a communication tool including a communication needle (not shown) is attached to the discharge portion 11a, and the liquid is communicated with a new infusion bag. This is performed by discharging the liquid remaining in the container 1 from the discharge portion 11a by gravity and aseptically mixing the liquid into the infusion bag. Thereby, the total amount of the first and second times becomes the total amount of the liquid stored in the storage chamber 3, and the predetermined amount of the liquid can be reliably administered to the patient. Further, if the first use amount is halved, the liquid can be surely discharged in equal parts.

In the liquid container of this embodiment used as described above, first, since the communication passage 4 is located at a position separated from the discharge portion 9b by a predetermined height or more, a liquid having a volume corresponding to the predetermined height is supplied. Can be stored in the storage unit 7b,
A single use of liquid can be stored. Since the partition on the discharge unit 9b side that discharges the liquid from the storage unit 7b blocks the adjacent storage unit 7a, only the liquid stored in the storage unit 7b is reliably discharged from the discharge unit 9b. The liquid stored in the other storage part 7a can be left in the liquid container 1 as a residual liquid. Therefore, by discharging the remaining liquid at the time of next use, the liquid stored in the liquid container 1 can be easily divided and used without exposing the liquid contained in the liquid container 1 to the outside air without performing a special operation. In addition, since the discharge units 9a and 9b are provided in the number corresponding to the storage units 7a and 7b, different discharge units 9a and 9b can be used for each of the storage units 7a and 7b. If maintained under sterile conditions, the discharge sections 9a, 9
Even if microorganisms adhere to the outer periphery of the discharge portion 9b used first in a container that is connected to another communication member and discharged, the liquid in the storage chamber 4 and the liquid discharged at the next use are not removed. It does not come in contact with microorganisms, so that microbial contamination can be prevented even when divided and used.

In this embodiment, the suspension holes 11
The discharge unit may be provided at a position that becomes the bottom of the storage unit 7a in a state where the storage unit 7a is suspended using a. With this configuration, the amount of liquid discharged during the second use can be adjusted by adjusting the amount of liquid stored in the storage unit 7a. Also, an example has been described in which the communication path 4 is disposed above the position of the liquid surface S of the liquid in use, but the communication passage 4 is at the same height as the position of the liquid surface S as indicated by a virtual line 12 in the drawing. The second communication path may be provided in the shape of a through-hole, and the tip of the partition portion 5, that is, the communication path 4 may be substantially at the same level as the liquid level as indicated by the imaginary line 13. You may. By doing so, it is possible to discharge the predetermined divided liquid amount without adjusting the position of the liquid surface of the storage units 7a and 7b, that is, without adjusting the amount of liquid stored in each of the storage units 7a and 7b. If the storage units 7a and 7b have the same capacity, the liquid in the storage chamber 3 can be easily divided and discharged in equal parts. Also, the number of discharge units provided is equal to the number of storage units, but one discharge unit can be used. After discharging the liquid in one storage unit, the liquid container is inverted and the liquid in the other storage unit is discharged to one side. After being moved to the storage section, it can be easily divided and used by being discharged again. Even in this case, the liquid in the storage chamber 3 can be divided without exposing the liquid to the outside air.
