It is about.

[0002]

2. Description of the Related Art Medical containers such as bags and containers for infusions, dialysis solutions, organ preservation solutions and the like used for infusion are generally resin containers. In addition, some infusions are infused with antibiotics or the like at the time of use, and are then injected by infusion after mixing. A syringe is used for such co-injection or mixing. For example, a lysate is placed via a syringe into a vial containing the antibiotic. The antibiotic and the lysis solution are mixed, and the mixture is drawn back out of the vial with a syringe. Then, the syringe is pierced through the outlet of the infusion container, and the mixed solution is filled in the infusion container. Recently, various types of medical containers provided with a connecting portion such as a vial have been proposed in order to eliminate such complicated operations. As a medical container provided with a connecting portion, a container provided with communication means in a container main body containing a drug solution or a solution, and a container main body and a drug container such as a vial are connected in advance by a connecting portion, and each of them is used until use. Some containers are placed in a state where they cannot communicate with each other. The former is commonly referred to as a so-called half-kit medical container, and the latter is referred to as a full-kit medical container.

[0003] A half-kit medical container is composed of, for example, a flexible container and a cylindrical housing capsule extending upward from the upper end of the container. A needle is accommodated, and at the time of use, one end of the communication needle is pierced into a rubber stopper at the mouth of the medicine container, and the other end of the communication needle is pierced through a rubber stopper provided at the upper end of the flexible container. There has been proposed a solution container provided with a communication means of a medicine container for communicating with the inside of the container (Japanese Patent Laid-Open No. 7-32).
No. 8097). The lower opening of the cylindrical capsule is hermetically connected to the upper end of the flexible container, the upper opening is sealed by a sterile maintenance sheet, and the communicating needle is aseptically contained in the capsule. Further, a flexible container, a cup material attached to the flexible container, a communication needle disposed in the cup material,
A medical container comprising a gasket that covers the communication needle has been proposed, a screw thread is formed in the cup material, and when the drug container is pierced through the communication needle, the inside of the drug container and the inside of the flexible container are reliably connected. A structure having the following structure has also been proposed (Table 2-50)
No. 3272).

[0004]

However, the conventional half-type medical container still has the following problems. Since the communication means provided at the connection portion of the medical container is a double-headed communication needle, it is necessary to arrange the medical device aseptically in the capsule and to be movable during use. In particular, when moving the medicine container, there is a requirement that the mouth of the medicine container must be pierced with a communication needle before the rubber stopper of the flexible container, so that the accommodation structure in the capsule may be complicated. is there. In addition, if the gasket is simply covered on the connecting needle, the connecting portion will be contaminated by the time of use.
The gasket must be sterilized before use. Therefore, according to the present invention, the connecting structure of the communication means in the connecting portion can be simplified, the number of parts can be reduced as much as possible to save labor in manufacturing, and the aseptic maintenance of the connecting needle can be easily maintained until use. It is intended to provide a medical container that can be used.

[0005]

According to the present invention, there is provided a medical container having a connecting portion for connecting a medicine container for co-infusion at the time of use to a resin container body having a flexible wall for accommodating a chemical solution. The connecting portion has a communication needle penetrating the mouth of the medicine container, a cap material having a pierced wall and a flexible wall that can be pierced by the communication needle, and a medicine material surrounding the cap material and surrounding the cap material. A cylindrical aseptic maintenance room capable of inserting the mouth of the container and a lid material that is detachably attached to the opening of the aseptic maintenance room are provided, and the communication needle is disposed in the connecting portion,
And the cap material is attached to the connection portion by directly or indirectly sealing the opening of the connection portion, and the aseptic maintenance chamber is formed integrally with the connection portion, or is separately formed. The lid material is formed of a vapor-permeable and bacteria-impermeable material, and the sterility-maintaining chamber is steam-sterilized together with the chemical solution in the container body and is aseptically maintained until use. The object has been achieved by providing a medical container characterized by the above-mentioned.

[0006] The chemical solution contained in the container body is generally an electrolyte solution. Examples thereof include Ringer's solution containing lactic acid, acetic acid, bicarbonate and the like, high calorie infusion containing sugar, amino acid, peptide, fat, etc., dialysate, organ preservation solution and the like.
The chemical may be a simple solution or dilution of the lyophilized drug, and the chemical may be simple sterile water. The chemical solution is subjected to a steam sterilization process after being stored in the container body in a liquid-tight manner.

[0007] The medical container main body has a flexible wall. The flexible wall may be any as long as the volume in the container is easily changed by bending. Further, it is desirable that the medical container wall has such transparency that the contents can be confirmed.
This is because it is necessary to confirm the state of the medicine in the container. The container body is made of a resin material, and is formed from an inflation film, a tube, a sheet, and a film, or is formed by extrusion, injection, or blow molding. The resin material for the container body is a general-purpose resin such as polyolefin resin, vinyl chloride, vinylidene chloride resin, polyester resin, polyvinyl alcohol resin, polyacrylonitrile resin, polyacrylic acid resin, polyamide resin, and the like. Further, the resin container may be formed in a single layer or a multilayer. The innermost layer that comes into contact with the drug in the container is preferably a resin layer that does not affect the drug and does not generate elutes. As such a resin, a polyolefin-based resin is desirable.
Medium and low-density olefin resins such as high-density polyethylene and polypropylene are exemplified. It is desirable that a gas barrier layer is formed on the container wall. In particular, a layer that does not easily transmit oxygen or the like is desirable. Examples of such a gas barrier layer include a metal layer made of aluminum or the like which hardly transmits gas at all or an inorganic vapor-deposited layer made of silicon oxide, magnesium oxide, titanium oxide, etc., and polyvinylidene chloride, polyester, nylon, ethylene, and the like. -A resin layer having a high gas barrier property, such as a vinyl alcohol copolymer and a fluororesin. The oxygen permeation amount of the gas barrier layer is 40 cc · 20 μ / m ² · day · a
tm (temperature: 20 ° C.) or less, especially 30 cc · 20 μ /
m ² · day · atm or less, preferably 5 cc · 2
0 μ / m ² · day · atm or less, further 1 cc · 20
It is desirably not more than μ / m ² · day · atm.

[0008] Examples of the drug to be co-injected into the above-mentioned drug solution include lyophilized products such as antibiotics and physiologically active substances, extracted drugs, and other drugs. It is. Examples of the medicine container include a glass container such as a vial, a resin container, and the like, and a sealing rubber stopper or the like for piercing is provided at the mouth. The medical container is one in which the medicine container is connected to the connecting portion of the container body when used. In addition, as long as the medicine container is a container provided with a portion to be pierced by a communication needle such as a rubber stopper, any type of container can be applied.

When the main body is formed of sheet resin, the connecting portion of the container main body is attached with a tubular resin port molding material or the like at the time of heat sealing at the end of the sheet. When the main body is a blow-molded product, the connection part of the container main body can be a blow-out port of blow air, or the connection part can be integrally formed with a portion other than the blow-out port. The communication needle is disposed in the connection portion. The communication needle is formed of a metal or resin molded product, but a resin molded product is desirable because of its workability and corrosion resistance. The communicating needle has a piercing portion penetrating the mouth of the medicine container and a base end fixed to the connecting portion.

The cap member covering the communication needle is attached to the connecting portion by directly or indirectly sealing the opening of the connecting portion. That is, the cap material covers the communication needle so as to close the communication opening of the communication needle with the outside world and secure the communication needle in the container body. The cap member has a pierced wall of the communication needle and a flexible wall. Therefore, when the communicating needle pierces the mouth of the medicine container through the pierced wall, the flexible wall shrinks, and the pierced wall is broken by the communicating needle and moved together with the mouth. Such a cap material may be a rubber elastic member or a soft bag-like material made of resin or the like. The aseptic maintenance room surrounding the periphery of the cap material is formed in a substantially cylindrical shape, and its base end is attached to a connecting portion of the container body or is formed integrally with the container body. The opening of the sterile maintenance chamber is formed in a size that allows the insertion of the mouth and the trunk of the medicine container. A lid is detachably attached to the opening of the sterility maintenance room, and the lid is made of a vapor-permeable and bacteria-impermeable material. Examples of such a lid material include a sheet in which a resin component is mixed with paper to form a predetermined pore, a sheet in which a water-repellent resin is laminated, and the like. As described above, with the vapor-permeable lid material, when the chemical solution in the container main body is subjected to the high-pressure steam sterilization treatment, the steam fills the aseptic maintenance room, and the surfaces of the aseptic maintenance room and the cap material are sterilized. Therefore, the aseptic maintenance room is subjected to steam sterilization processing together with the chemical solution in the container main body, and is maintained aseptically until use.

In the medical container according to the present invention, the number of parts is extremely small, and the surfaces of the cap material and the communication needle are maintained aseptically until use. The manufacturing process is simplified at the time of manufacturing, and sterilization in the communication portion can be performed together with the container body. Further, since the communication needle is not configured to be movable in the connecting portion unlike a double-ended needle communication needle, the structure can be made extremely simple. At the time of use, first, the lid material is peeled off from the sterility maintenance room, the mouth of the medicine container is inserted into the sterility maintenance room, and the mouth is brought into contact with the tip of the cap material. If the medicine container is further pushed in in this state, the cap material is broken and the piercing portion of the communication needle is inserted into the mouth. Then, the inside of the medicine container and the inside of the container main body are communicated via the communication needle, and the medicine in the medicine container can be co-injected into the medicine solution. Therefore, the operation of the medical container at the time of use becomes extremely simple.

A medical container according to a second aspect of the present invention is the medical container according to the first aspect, wherein the communication needle has a piercing portion, a base flange portion, and an insertion skirt portion, By inserting the insertion skirt portion into the connection portion, the connection needle is positioned and fixed to the container body. The communication needle according to the present invention is provided with an insertion skirt portion in addition to the basic portions such as the piercing portion and the mounting flange portion.
With the insertion skirt portion, the communication needle can be easily inserted and fixed into the opening of the connection portion when assembling the container. Further, the medical container according to claim 3 of the present invention is the medical container according to claim 2, wherein the base end of the cap material is wound around the base flange portion so that the cap material is attached to the communication needle. It is characterized by being positioned and fixed. If the cap material is put on the communication needle from the beginning and wound around and fixed to the flange of the communication needle, the cap material can be easily positioned and fixed to the connection portion simply by inserting the communication needle into the connection portion.

The medical container according to a fourth aspect of the present invention is the medical container according to the second aspect, wherein the cap is provided on the communication needle in addition to the communication opening with the medicine container formed in the communication needle. A drain hole for communicating the inside with the inside of the main body is formed at the base end of the base end flange portion or the piercing portion. In the medical container according to the present invention, usually,
The liquid may remain between the outside of the communication needle and the inside of the cap material during high-pressure steam sterilization. Such a residual liquid may squirt when the punctured wall of the cap material is opened during use. That is, when the mouth portion of the medicine container is pressed toward the cap material during use, the cap material wall bends, the inside of the cap material shrinks, and the residual liquid loses a place to go. There is a risk of blowing out from the puncture. In this case, it can be prevented to some extent by forming the cap material with a rubber elastic material, and it is desirable to form the cap material with an elastic material. However, since further safety is required for the medical container, if a liquid draining hole is formed in the proximal end flange portion of the communication needle or the proximal end of the piercing portion, the liquid is discharged from the container through the liquid draining hole. Since it returns to the main body, the ejection of the residual liquid as described above is almost prevented.

A medical container according to a fifth aspect of the present invention is the medical container according to the first aspect, wherein the communication opening formed in the communication needle with the medicine container is pierced through the mouth of the medicine container. It is characterized by being closed liquid-tight with an elastic material until time. By closing the communication opening of the communication needle with the elastic material, it is possible to prevent liquid from remaining between the outside of the communication needle and the inside of the cap material during the high-pressure steam sterilization. As such an elastic material, the cap material itself may be an elastic material, and an elastic material other than the cap material may be disposed in the communication opening.
The elastic material is rubber, elastomer, or the like. The medical container according to claim 6 of the present invention is characterized in that, in the medical container according to any one of claims 1 to 5, a finger hook protruding from an outer wall surface is formed in the sterility maintenance room. And
If a finger hook is formed in the sterility maintenance room, the medicine container is pushed into the sterility maintenance room with one hand when connecting the drug containers,
It can be easily connected to the container body. While touching the bottom of the medicine container with the thumb, the index finger and the middle finger can be hung on the finger hook to push the medicine container.
