Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drug solution kit, and more specifically, a drug solution and a solution for dissolution are separately prepared, and the drug solution and the solution for dissolution are mixed by separating them before use to prepare a drug solution. The present invention relates to a medicinal solution kit.

[0002]

2. Description of the Related Art Conventionally, a drug solution kit is known which can be used as a drug solution by mixing a drug and a solution for dissolution just before use. For example, Japanese Utility Model Application Laid-Open No. 2-86536 discloses an infusion container having a bag in which a dissolution solution is enclosed and a capsule holding a vial. In this container, by rotating the capsule, the cap portion of the vial is pierced by the puncture needle fixed to one end of the bag, whereby the dissolution solution and the drug are mixed. In contrast to the above-mentioned utility model, Japanese Patent Application Laid-Open No. 5-192377 discloses an infusion device in which a puncture needle attached to a bag is made movable and a vial cap is pierced by the puncture needle.

With these, it has become possible to easily mix the drug and the solution for dissolution, but there are still unsolved problems. For example, since both use a puncture needle,
There are safety problems such as the possibility of accidental finger sticks during use and the need to be careful about disposal after use. In addition, if the puncture needle is accidentally pushed in, there is a problem that the drug and the solution for dissolution are mixed.

[0004]

Therefore, there has been a demand for providing a drug solution kit which allows a drug and a solution for dissolution to be easily mixed without using a puncture needle.

[0005]

Means for Solving the Problems As a result of intensive studies to solve the above-mentioned problems, the present inventors have found that a connector for connecting a drug container and a dissolution container opens a liquid passage by separating the connector. The present invention has been completed by finding that it is possible to easily mix a drug and a solution for dissolution without using a puncture needle.

That is, the present invention includes a dissolving container filled with a dissolving liquid, a drug container filled with a drug, and a connecting means for connecting them, and the connecting device includes a dissolving container connecting part, a drug container housing part, and a connecting part. A drug solution kit comprising a connector that enables liquid flow, and by separating the dissolution container coupling part and the drug container storage part from each other, the liquid passage tube in the connector is opened to mix the drug and the dissolution liquid. .

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below with reference to the drawings showing the embodiments of the present invention.

FIG. 1 is a view showing the external appearance of a liquid medicine kit of the present invention, FIG. 2 is a cross-sectional view showing the state of the coupling means when the liquid cannot be passed (medicine container not mounted), and FIG. It is sectional drawing of a coupling means when a liquid is made possible. In the figure, 1 is a drug solution kit, 2 is a dissolution container, 3 is a drug container, 4 is a coupling means, 4a is a dissolution container coupling part, 4b is a drug container storage part, 4c is a connector, 5 is a stopper, 6 is a liquid passage pipe, 7 is a partition wall, 8 is a support plate, 9 is a thread groove, and 10 is an elastic ring.

As shown in FIG. 1, the drug kit of the present invention comprises a dissolving container 2, a drug container 3 and a connecting means 4 connecting them. As will be understood from FIGS. 2 and 3, the connecting means 4 is composed of a dissolving container connecting portion 4a having a stopper 5 at the tip portion, a drug container storing portion 4b, and a connector 4c.

A medicine container accommodating portion 4b constituting the connecting means 4
Is provided with a thread groove 9 and an elastic ring 10 on the upper side, and it is possible to hold and seal the drug container in this portion. Also, on the lower side, the closing plug 5 held by the support plate 8
Is provided. Since the support plate 8 is a fin formed radially around the closing plug 5, liquid can freely pass between the support plates 8. On the other hand, the dissolution container coupling part 4a is adhered or fused to the dissolution container 2 filled with the dissolution liquid at the lower part thereof, and the upper part thereof is
Similar to the medicine container storage portion 4b, a closing plug 5 held by the support plate 8 is provided. Since this support plate 8 also has the same configuration as described above, the liquid freely flows between them. Further, the connector 4c has a partition wall 7 near its center,
A liquid passage tube 6 is provided at the center thereof.
Further, ring-shaped projections 12 that engage with the distal end projections 11 of the dissolution container coupling portion 4a and the drug container storage portion 4b are provided at positions of about 1/4 above and below the connector 4, respectively, to prevent liquid leakage. Has a function to prevent.

In the medicine kit of the present invention, the mechanism through which the liquid passage pipe 6 in the connector is opened and the medicine and the solution for dissolution can be mixed is as follows. First, the dissolution container coupling portion 4a and the drug container storage portion 4 during distribution and storage
The state of b and the connector 4c is the state shown in FIG. In this state, since the liquid passage pipe 6 is closed by the stoppers 5 from above and below, the dissolving liquid (not shown) in the dissolving container 2 can flow into the dissolving container connecting portion 4a. However, it cannot flow into the medicine container storage portion 4 b and further into the medicine container 3 via the liquid passage pipe 6.

On the other hand, when the dissolution container connecting portion 4a and the drug container storage portion 4b are separated from each other during use, the stoppers 5 that have closed the liquid passage pipe 6 in the connector 4c are respectively separated as shown in FIG. According to the movements of the dissolution container coupling portion 4a and the drug container storage portion 4b, the dissolution container coupling portion 4a and the medicine container storage portion 4b move upward and downward to form a gap and open the liquid passage pipe 6. As a result, the melting container 2
The dissolution liquid therein flows into the medicine container storage portion 4b through the dissolution container coupling portion 4a, the newly formed gap, the liquid passage pipe 6, and the newly formed gap, and further flows into the medicine container 3. By doing so, it becomes possible to mix with a drug (not shown).

In the above-mentioned medicine kit, the medicine container 3 and the medicine storage portion 4b can be screwed, but the invention is not limited to this, and as long as the fixing and the leakage of the dissolving liquid can be prevented. It can be used without particular restrictions. For example,
Alternatively, the outer circumference of the drug container mouth may be made of an elastic material and held by the elastic force in the drug container, or the outer circumference of the drug container mouth may be bonded or fused to the drug container.

Further, the dissolving container 2 is made of a water-impermeable material of various materials, but in general, a flexible polymer material such as soft vinyl chloride resin or polyolefin resin is preferably used. .

Further, the material forming the coupling means 4 has such elasticity that it can surely seal the liquid passage pipe at the time of distribution and the like, and the hermeticity so as not to leak water from an unnecessary portion at the time of use. It is necessary that the material be a material that can provide high quality and high working accuracy. Examples of materials made of such materials include thermoplastics such as polyvinyl chloride, polyethylene and polypropylene, and thermosetting plastics such as epoxy resin and polyurethane.

Furthermore, although the drug and the solution for dissolution used in the drug kit of the present invention are not particularly limited, for example, it is applicable to a drug which is preferably dissolved immediately before use in terms of stability and the like. Therefore, a great merit can be obtained. Examples of such agents include:
Ampicillin, carbenicillin, sulbenicillin, ticarcillin, cefazoline, ceftizoxime, cefotiam, cefmenoxime, cefacetril, cefamandole, cephaloridine, cefotaxime, cefotetan,
Antibiotics such as cefoperazone, cefsulodin, ceftezole, cefpyramide, cefmetazole, cefuroxime, vancomycin, piperacillin, fosfomycin, flomoxef, imipenem cilastatin, meropenem, and their salts, mitomycin C, fluorouracil, tegafur, antitumor agents, etc. Examples thereof include anti-ulcer agents such as famotidine, ranitidine, and cimetidine, salts thereof, and agents such as oxyglutathione that need to be dissolved or mixed before use. In addition, examples of the solution for dissolution include distilled water for injection, physiological saline, glucose solution, and infusion solutions and diluting agents in which appropriate vitamins and electrolytes are added.

In the medicine kit of the present invention, the liquid passage pipe 6 is opened by an unconventional pulling operation, so that the medicine and the dissolving liquid are erroneously compared with the conventional product adopting the pushing operation. However, in order to prevent such accidents more, for example, the drug container and the part of the coupling means are packed with, for example, a shrink film and the like, and in use, the peeling provided on the film is used. The tape may be peeled off from the tape or the peeled portion.

Further, in the above description, the medicine container 3 is already set, but for example, the medicine container 3 and the other portions (the dissolution container 2 and the bonding means adhered or fused thereto). 4), which separately sells a drug dissolving bag having a joint part that is compatible with the mouth of the drug container 3, and selects the drug container 3 containing the necessary drug at the medical institution to use for dissolving the drug. It can also be used in combination with a bag.

[0019]

The present invention connects the dissolution container 2 and the drug container 3 to allow the dissolution liquid to flow, by replacing the puncture needle and separating the dissolution container coupling part and the drug container storage part, respectively. It takes a new means of moving the stopper plug provided at the tip of the connector to open the liquid passage pipe in the connector.

[0020]

The pharmaceutical kit of the present invention does not use a puncture needle, and therefore has no possibility of accident or disposal after use. In addition, since the movement of pulling apart, which is relatively unlikely to cause an error, is used, it is unlikely that an accident will occur in which the drug and the dissolving liquid are mistakenly mixed.

Further, since the medicine container can be made selectable, it can be used as a general medicine kit.

Therefore, the medicine kit of the present invention has few accidents and is versatile, and can be widely used in the medical field.
