し込んでなるものである。 For example, when a certain solid powder is used by dissolving it in a solvent, it is often necessary to dissolve it immediately before use because if the solution is prepared in advance, the quality of the solution deteriorates during storage. To meet this need, there is a mixing package in which two types of substances to be mixed are stored separately in the same container and are combined immediately before use. One example is a bag in which a liquid serving as a solvent and a powder to be dissolved in the solvent are separated by a weak seal, that is, a heat seal with low peel strength. By applying external pressure to the part, the weak seal peels off, the two substances mix, and a solution is formed. However, in this mixing package, the weak seal portion may peel off due to vibration or pressure applied from the outside during handling, resulting in mixing of the two substances. If the heat seal strength is increased, it will be difficult to apply pressure to the liquid and peel it off. The inventors have improved the above-mentioned drawbacks of the mixing package, invented a mixing package that can store two or more substances reliably separated, and mix them immediately before use, and have disclosed the above. (Special application 1986-153701)
No. 63-9441). In the mixing package of the invention, when the gassho-attached seal part of the outer bag is strongly pulled from side to side, the heat-sealed part of the inner bag peels off (or breaks), and the substance A in the inner bag is transferred to the outer bag. Substance B
That is, the two substances are combined with a solvent and the bag is squeezed or shaken to mix the two substances to create a solution. On the other hand, syringes and devices with similar structures have been widely used as devices for injecting liquids for a long time. However, syringes have a limited capacity and cannot inject a large amount of liquid at once. Also,
Conventional injection devices have the disadvantage that the liquid and needle are easily exposed to air during injection. Furthermore, in order to facilitate the use of robots, there has recently been a demand for injection instruments that can be operated with simple actions, for example, by continuous or stepwise movement in a fixed direction. The inventors solved the limitations and difficulties of the above-mentioned syringes and invented an injection device that met the above requirements, and they had already proposed this (patent application filed in 1983).
-17298, JP-A-62-182048). The new injection device has a hollow syringe needle with a sharpened tip and rear end fixed in the middle to a fixed part of the needle holder, and a stopper holder with a stopper made of a soft material at the bottom.
The injection needle is fitted into the needle holder so that it can move forward in the axial direction, and the rear end of the injection needle is inserted into the inside of the stopper.

ブルなく行なうことができる。 In the mixed injection cartridge shown in the drawing, the package is housed and protected in a cylindrical case during storage, so even if strong external pressure is applied during handling, the inner and outer bags will not break unless the case is destroyed. The bag will not break. To use this mixing infusion cartridge,
As shown in FIG. 1, the lid 6 is raised from the cylindrical case body 5, and the injection device 4 is attached to the package 1.
is removed from the lid 6, and the two types of substances inside the package 1 are mixed. That is, the gassho stickers 31A and 31B on the outer bag 3 of the package 1 are
When the heat seals 23 and 24 of the inner bag 2 shown in FIG. 7 are pulled strongly from side to side as shown in FIG. 0, the heat seals 23 and 24 of the inner bag 2 shown in FIG. Substance A in the inner bag is substance B in the outer bag
That is, it combines with the solvent. Dissolved solution C is created by mixing the two substances by squeezing or shaking the bag. After performing the above operations,
As shown in the figure, the needle holder of this injection device 4 is fitted into the tip 51 of the cylindrical case body 5. Next, as shown in FIG.
Fits into 1. Thereafter, as shown in FIG. 5, when the slide stopper 7 attached to the case body 5 is moved forward in the direction shown by the arrow, the flange 13 provided on the top 11 of the package fits into the slide stopper 7. and the top 1 of the package at the same time.
1 also moves forward. Since the injection needle 41 is fixed to the needle holder 42, its rear end passes through the plug 12 made of a soft material and reaches the inside of the package 1. In this way, as shown in FIG. 6, the package 1 and the receiving container 8 are connected by the hollow injection needle 41. Therefore, as shown in FIG. 4, when pressure is applied by pressing the toy-shaped body 61 rotated by 180 degrees against the package 1, the solution C is injected into the container 8 on the receiving side. The injection operation can be interrupted by retracting the slide stopper 7. The needle holder 42 of the injection device 4 is fitted and fixed to the tip of the case lid 6 during storage, and to the tip 51 of the case body 5 during use. It will never fall off. Since the rear end of the injection needle 41 is stuck inside the stopper 12, it does not come into contact with air. When the tip of the injection needle 41 is covered with a cap, the entire injection needle 41 is not exposed to air, and its sterility can be maintained. When dispensing the solution C, the top 11 of the package is pulled back to the rear of the needle holder 42, and the rear end of the injection needle 41 returns to the inside of the stopper 12. Therefore,
Communication with the package 1 is broken and the package 1 is resealed. If the tip of the injection needle 41 is then pulled out from the receiving tube 81 of the container 8 on the receiving side, the solution C will not leak. Effects of the invention If the mixing injection cartridge of the invention is used,
Separation of two or more substances to be mixed is extremely reliable, and there is little risk of them mixing during storage. Immediately before use, they can be mixed and dissolved or dispersed without exposure to air, and the resulting solution or dispersion can be poured into another container without any trouble.
