Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical container such as an infusion bag used for drip injection.
More specifically, the present invention relates to a medical container having a mixed injection port for mixing another drug into an administration liquid (infusion or the like) in a container body.

[0002]

2. Description of the Related Art Generally, a bag for an infusion solution or a medical container such as a container, which is used for an infusion injection, has a discharge port for taking out the infusion solution at the time of infusion. In addition, in terms of treatment, other drugs such as vitamins may be mixed and injected into the container body with a syringe.In such a case, a mixed injection port with a structure similar to the discharge port is installed in advance in the container body and the syringe is injected from the mixture injection port. Through the inside of the container body. Further, some medical containers that mix other drugs for infusion during use have a mixed injection port (or connection port) with a drug container (vial) in addition to the discharge port. Further, a so-called drug kit, which is provided in advance with a drug container connectable thereto, is also provided.

In general, medical containers such as infusion bags and containers are non-constant volume plastic containers having flexible and flexible walls. Examples of resins for such containers include linear low-density polyethylene resin, high-density polyethylene resin,
Flexible materials such as polypropylene resin, soft polyester resin, chlorinated polyethylene resin, vinyl chloride resin, and ethylene-vinyl acetate copolymer are used.
In addition, a container molded product is generally formed by cutting two extruded stretch-molded sheets or films, or an inflation-molded tubular sheet into a predetermined size, and heat-sealing the peripheral edges thereof. . Recently, blow molding resin containers have already been provided. Further, it has already been proposed that these resin molded products are made of a multilayer laminate to further stabilize the filling in the container.

Further, a conventional medical container has a discharge port or a mixed injection port, which is a cylindrical resin mouth member attached to the container body by heat sealing, and a rubber stopper for closing the mouth of the mouth member in a liquid-tight manner.
It comprises a ring-shaped stopper for completely fixing the rubber stopper to the mouth member. And, the tubular mouth member and the ring-shaped stopper member are both molded products of general-purpose resin,
It is fixed by heat welding or an adhesive. Then, when the infusion solution is taken out from the container body or when another drug is mixed and injected, the communication needle is pierced into the rubber stopper. Further, in a medical container to which a drug vial is connected, in addition to a discharge port for discharging the administration liquid in the container body, a connection port (mixed injection port) for connecting with a drug vial is installed in the container body. Is provided with a communication needle for communicating the inside of the container body with the inside of the drug vial. A double-ended puncture needle type has been proposed as a communication needle. In use, such a communicating needle has a structure in which one pricking portion pierces a thin film or a rubber stopper of a connection port, while the other piercing portion pierces a drug container, for example, a rubber stopper of a vial to communicate them. .

[0005]

However, the conventional mixed injection port for a medical container is extremely complicated in its manufacture and is economically problematic. Conventionally, the mouth member of the mixed injection port of the medical container is inserted between the sheets similarly to the member of the discharge port, and is liquid-tightly attached by a heat welding seal. In such a heat-sealing seal, since the mouth member is tubular, the sealing surface is curved and the sheet comes into contact with the sealing means in a state of being bent. Therefore, liquid-tight heat-sealing is difficult, and pinholes sometimes occur. Further, the heat-welded portion of the sealing means is also curved and the durability of the apparatus is deteriorated. Further, the position of the mouth member of the mixed injection port is limited to the heat-welded portion between the sheets, and the position is limited to the upper portion or the lower portion when the medical container is used. In particular, when the discharge port is formed in the lower part, it is often installed in the upper part, which often imposes a disadvantageous posture on the mixed injection operation.

Therefore, an object of the present invention is to provide a medical container in which the mixed injection port can be attached very easily, and the position of the mixed injection port can be freely set in a suitable portion of the container body, thereby facilitating the mixed injection operation. To provide.

DISCLOSURE OF THE INVENTION According to the present invention, in a medical container in which the container main body is made of a plastic wall and a discharge port for discharging the administration liquid is provided, an area in which a communication needle can be pierced is set. An elastic member having a piercing hole that is kept liquid-tight by compressing the outer peripheral wall of the pierced communication needle through elastic force.
The elastic member is placed around a region where a piercing hole is formed in a liquid-tight manner, and a mixture is directly or indirectly attached to the wall surface of the container body in a liquid-tight manner. The above object is achieved by providing a characteristic medical container.

In the medical container of the present invention, the mixed injection port is formed integrally with the stopper and the stopper, or is fixed in a liquid-tight manner and attached to the wall of the container body in a liquid-tight manner. It can be characterized in that it is composed of an adhesive material to be worn. In the medical container of the present invention, the mixed injection port is integrally formed with the stopper, the retaining member attached to the retaining member and retaining the elastic member, and the retaining member or the retaining member, or It may be characterized in that it comprises an adhesive material which is liquid-tightly fixed and attached and which is liquid-tightly adhered to the container body wall.

In the medical container of the present invention, the mixed injection port is provided with a finger hook portion which is separated from the wall surface of the container body by a predetermined distance, so that the communicating needle is pierced at the mixed injection port. Communication operation becomes easy. In the medical container of the present invention, the communication needle of the elastic member surrounds the outer surface of the region to be pierced and has an aseptic container that is maintained aseptically until the time of use, and the aseptic container is aseptic. And has a communicating needle that communicates with the inside of the container body when the elastic stopper is pierced. Also,
The sterile filter is aseptically accommodated in the sterile container together with the communication needle. Further, there is provided a medical container, which is preliminarily provided with a drug container which is in communication with the container body and is filled with a drug to be mixed with the administration liquid in the container body.

[0010]

The above-mentioned medical container is extremely simple to manufacture because it has a simple structure in which the elastic member is liquid-tightly attached to the wall of the container body. That is, unlike the discharge port, the mixed injection port does not serve as a filling port for the administration liquid of the container body, and therefore, it is not necessary to provide the mixed injection port with a mouth member shape or a rubber stopper. The idea of the mixed injection port here is that an elastic member that seals the outer circumference of the communication needle when the communication needle is pierced is liquid-tight and that supporting the elastic member is liquid-tightly attached to the wall of the container body. If it does, it will completely fulfill the role of a mixed injection port. In other words, since the mixed injection port is different from the discharge port used as a mouth for filling the administration liquid, there is no need for a mouth member or a mouth port communicating with the inside of the container body unlike the conventional discharge port. As long as there is no liquid leakage from the piercing part or the passage of externally contaminated air when the communicating needle pierces, the original function is exerted. Therefore, in the case of the mixed injection port installed in the medical container of the present invention, since each member is simply attached to the container wall, the heat welding means and the seal portion do not need to be curved, and a reliable liquid tightness is ensured. Can be sealed. Further, it may be an applique type that can be easily installed at a desired position on the container wall. Further, a sterile container can be formed, and an infusion tool, a communication needle of an infusion set, and the like can be aseptically stored. Further, by accommodating a sterilization filter and the like together with the communication needle, when the drug is mixed with a syringe or the like, even if the drug is contaminated, the sterilization filter removes bacteria etc. Therefore, there is no risk of contaminating the inside of the container body with a mixed injection drug or the like. Therefore, nosocomial infection and the like can be prevented as much as possible during operations such as infusion.

Further, it has an adhesive sheet 10 which is liquid-tightly fixedly attached to the stopper 9 and is liquid-tightly attached to the outer wall of the container body 2. Further, it also has a holding member 8 which is attached to the stopper member 9 and holds the elastic rubber 6. Further, it has a finger hook 13 which is separated from the wall surface of the container body 2 by a predetermined distance. Further, the elastic rubber 6 has a sterile container 9B which surrounds the outer surface of the region where the communication needle 7 is pierced and the inside of which is maintained aseptically until use, and is aseptically housed in the sterile container 9B. It has a communicating needle 7 that communicates with the inside of the container body 2 when a needle is inserted into the rubber 6. Furthermore, the sterile filter 14 is aseptically accommodated in the aseptic container 9B together with the communication needle 7.

The medical container 1 according to this embodiment will be described in more detail. The container body 2 is made of a non-constant volume resin container. Specifically, the container body 2 is formed by stacking two laminated sheets formed by an inner layer made of stretch-extruded low-density polyethylene and propylene and an outer layer made of linear low-density polyethylene. That is, the peripheral edges of the sheets are heat-sealed to each other, and the discharge port 3 is attached together with the formation of the peripheral edge seal portion 2A. The discharge port 3 is composed of a conventionally known mouth member, a rubber stopper, and a stopper member for the rubber stopper, and the mouth member, which is a resin molded product, is liquid-tightly fixed between the sheets when the above-mentioned seal portion 2A is formed. Further, a suspending hole 4 for the container is formed in the peripheral edge seal portion 2A on the side facing the discharge port 3. Then, in this embodiment, the mixed injection port 5 is attached to the outer surface of the sheet before the formation of the seal portion 2A.

As shown in FIGS. 2 and 3, the mixed injection port 5 is made of elastic rubber 6, and the elastic rubber 6 has a flat cross section so that the communicating needle 7 can be pierced. The elastic rubber 6 can press the outer peripheral wall of the communicating needle 7 pierced through its elastic force, and the piercing hole can be kept liquid-tight. Therefore, although the rubber material is used in the present embodiment, the elastic member of the mixed injection port 5 in the present invention may be a thermoplastic resin elastomer or the like as long as the above-described effects are obtained. The elastic rubber 6 is fixedly held by the holding material 8 and the holding material 9 of the resin molded product, and the holding material 9 and the holding material 8 are fixed to each other by thermal welding.

The adhesive sheet 10 is made of a resin sheet, is formed in a donut shape, and has an inner peripheral edge inserted and attached between the holding material 8 and the stopper material 9. The same resin as that of the outer layer of the sheet of the container body 2 is used as the resin of the adhesive sheet 10, and liquid-tight and complete sealing is possible at a temperature lower than the heat-sealing sealing temperature between the inner layers. Therefore, the adhesive sheet 10 is liquid-tightly adhered to a predetermined position of the container body 2 by heat sealing, and at the time of such adhesion, even if the sheets of the container body 2 are sealed in a stacked state, the container body 2 The sheets are not completely heat-welded to each other.
Therefore, it is possible to seal the insides of the sheets without contaminating the inside with a sealing jig or the like. In this embodiment, a resin sheet is used and the adhesive sheet 10 is formed by heat-sealing.
Was adhered to the wall of the container body 2, but the adhesive material is not limited to this and may be paper other than a resin sheet that is strong and does not allow bacteria and the like to pass through. You may go.

The cylindrical portion of the stopper 9 is formed as a sterile container 9B, and the seal member 12 and the finger hooking member 13 are attached to the end opening 11 of the container 9B. The sealing material 12 is formed of a sheet known per se that is permeable to water vapor gas, and the water vapor gas permeates during high pressure steam sterilization to sterilize the inside of the accommodating portion 9B with high pressure steam. Therefore, the inside of the housing portion 9B becomes a sterile housing portion that is sterilized by high-pressure steam sterilization and maintained in a sterile state by the liquid-tight sealing of the sealing material 12. Further, since the sterile container 9B is opened during its use, the sealing material 12 can be peeled from the end opening 11.
The finger hooking member 13 is a resin molded product formed in a tubular shape and is externally fitted to and attached to the end of the housing portion 9B, so that the finger hooking portions 13A, 13A are formed with a brim. Therefore, the finger rest 1
A finger 21 can be inserted between 3A and the wall surface of the container body 2.

The sterile needle 9B accommodates the communication needle 7 and the sterilization filter 14 connected to the communication needle 7.
The needle portion 7A is partially inserted into the fitting hole 6A formed on the outer surface of the elastic rubber 6. The communication needle 7 is connected to the housing 15 of the sterilization filter 14, and the housing 15 prevents the portion of the puncture portion 7A exposed to the outside air after the sterile container 9B is opened from entering the container body 2. ing. The housing 15 connected to the communication needle 11 supports the sterilization filter 14 together with the opposing housing 16, and the sterilization filter 14 is supported via a support net (not shown). The injection port 20 of the syringe is connected to the connection port of the housing 16. Housing 1
Groove portions 17 are formed at predetermined positions on the outer peripheral portions of 5, 16 and the projections 18 formed on the inner wall of the sterile container 9B are inserted into the groove portions 17.

When assembling the mixed injection port 5 as shown in FIG. 3, the elastic rubber 6 and the adhesive sheet 10 are arranged between the stopper 9 and the holder 8, and the ultrasonic sealer is used at the arrow A in FIG. The elastic rubber 6 is kept liquid-tight by heat welding. Next, as shown by the arrow B in FIG. 3, the adhesive sheet 10 is attached to the flat container body 2
It is pressed against the outer wall surface of the and heat-sealed with a heat-sealing device. In this case, the temperature of the heat-sealing seal is the container body 2
The temperature is set to be lower than the seal forming temperature of the peripheral edge seal portion 2A so that the stacked sheets of the container body 2 are not heat-welded to each other. Next, the finger hooking member 13 is attached to the tip of the aseptic container 9B as shown by the arrow C in FIG. Then, as shown by the arrow D in FIG. 3, the sterilization filter 14 and the communication needle 7 are housed in a predetermined position of the sterile container 9B, and the sheet member 12 seals the opening of the sterile container 9B. Next, the container body 2
After forming, the infusion solution 23 as the administration liquid is filled from the discharge port 3, the discharge port 3 is closed with a rubber stopper, and then high-pressure steam sterilization is performed. Therefore, together with the infusion solution 23 in the container body 2, the inside of the sterile container 9B is sterilized by high-pressure steam, and the high-pressure steam sterilization is performed based on the high-pressure steam sterilization method of the Japanese Pharmacopoeia. The inside of the autoclave is, for example, 100% after being replaced with an inert gas.
The temperature is from 130 to 130 ° C.

In the medical container 1 according to this embodiment, the following operational effects can be seen. First, first, the medical container 1 is suspended from the suspension member 24 through the suspension hole 4. Then, the index finger and the ring finger 21 of the left hand are hooked on the finger gripping member 13 to pull the outer wall of the container body 2 on the front side.
Then, the sealing material 12 is peeled off, and the injection port 20 of the syringe is connected to the connection port of the housing 16 of the sterilization filter 14 as shown in FIG. 2 (B). In this case, aseptic container 9B
The ejection opening 20 is completely connected to the connection opening of the housing 16 because the protrusion 18 on the inner wall of the housing blocks the movement of the housings 15 and 16. After sufficient connection, rotate the syringe a little to align the protrusion 18 with the groove 17 of the housings 15 and 16,
Make it movable. Then, as shown in FIG. 3C, the puncture portion 7A of the communication needle 7 pierces the elastic rubber 6 and the wall of the container body 2 to communicate the inside of the syringe with the inside of the container body 2. In this case, the insertion of the communication needle 7 is regulated by the connection port of the housing 15 so as not to be excessive, and only the puncture portion 7A that is not exposed to the outside air enters the container body 2. In addition, the finger rest 13
Since A is attracted, there is no possibility of penetrating the wall of the container body 2 which faces.

When the communicating needle 7 is pierced through the elastic rubber 6 and the wall of the container body 2, the elastic force of the elastic rubber 6 closes the piercing hole pierced by the communicating needle 7 in a liquid-tight manner. Even if the wall is broken, the liquid inside does not leak or the outside air does not enter the container body 2 due to the elastic force of the elastic rubber 6. Further, when the sealing material 12 is peeled off, the aseptic container 7 is opened at the time of use, and the communication needle 7 is exposed to the outside air, which may cause contamination. However, since the pricking portion 7A of the communication needle 7 that is pricked into the container body 2 is covered with the fitting hole 6A of the elastic rubber 6 fitted in a sterile state, it is not exposed to the outside air during the operation. . Further, since the movement of the communication needle 7 is restricted by the housing 15, the portion of the puncture portion 7A exposed to the outside air does not enter the container body 2. Further, it is possible to prevent the opposing wall of the container body 2 from being ruptured by the excessive penetration of the communicating needle 7. Therefore, the operation of connecting the communication needle 7 to the container body 2 is completely safe and is performed aseptically, and infection in a hospital is prevented as much as possible. In the above-mentioned embodiment, the connection port of the housing 15 is used as the restriction portion for the excessive puncture needle, but a restraining protrusion may be formed on the communication needle 7 or the like. Further, since the disinfection filter 14 is provided, even if the drug is contaminated when the drug is filled in the syringe, the disinfection filter 14 removes the contaminating bacteria and then the mixture is injected into the container body 2. It Therefore, the contaminated bacteria do not enter the patient together with the infusion solution 23. Therefore, even if a contaminated drug or the like is co-injected, nosocomial infection of a patient is reliably prevented.

Secondly, the medical container 1 of this embodiment has a simple structure in which the elastic rubber 6 is liquid-tightly adhered to the wall of the container main body 2. Extremely simple and easy to install. That is, unlike the discharge port 3, the mixed injection port 5 does not serve as a filling port for the administration liquid in the container body, so that it is not necessary to provide the mixed injection port 5 with a mouth member shape or a rubber stopper.
Therefore, a curved portion is not required for the heat-welding portion or the like, and ultrasonic heat-sealing or heat-sealing can be easily performed on the flat portion. Therefore, in the case of the mixed injection port 5 installed in the medical container of the present invention, since each member is simply attached to the container wall, the heat welding means and the seal portion do not need to be curved, and a reliable liquid can be obtained. Can be tightly sealed. Further, it may be an applique type that can be easily installed at a desired position on the container wall. Therefore, the mixed injection operation is not adversely affected. Further, the aseptic container 9B described above can be easily formed, and the infusion tool, the communication needle of the infusion set, and the like can be aseptically accommodated.

In this embodiment, the polyolefin resin container is used, but other general-purpose resin containers may be used. The resin layer of the container may be a single layer. In addition, in this example, a molded product was used in which two extruded stretched sheets or films were superposed on a container and cut, and a predetermined peripheral edge was heat-sealed. However, the container need not be an extrusion stretch-molded sheet, and may be, for example, a blow container molded product or a container molded product obtained by cutting an inflation-molded tubular sheet at a predetermined position and heat-sealing a predetermined portion. May be. In the present embodiment, the sterile container 9B is integrally formed with the stopper 9, but in the present invention, it is not always necessary to integrally form the stopper 9 and may be a separate member. Further, it may be integrally formed with the holding material 8. In the present embodiment, the sterilization inside the aseptic container 9B is high-pressure steam sterilization. However, in the present invention, it is not necessary to limit to steam sterilization, irradiation sterilization with γ-rays or electron beams,
Alternatively, the sterilization treatment may be performed by chemical gas sterilization such as ethylene oxide. Although the adhesive sheet 10 is provided between the holding material 8 and the stopper material 9 in this embodiment, only the holding material 9 is provided.
Alternatively, it may be provided only on the stopper 9, or may be integrally formed with these. In the above embodiment, the communication needle 7 and the sterilization filter 14 are provided in the sterile container 9B. Is also good.
