2. Description of the Related Art Infusions are often administered with other drugs, such as vitamins, trace element preparations, heparin, etc., but cannot be converted into pre-mixed products due to deterioration during storage after mixing. In such a case, it is customary to take out the individual formulation with a syringe or the like each time and inject the formulation from an infusion container or a side tube of an infusion route to mix. However, the above operation is complicated and there are many opportunities for contamination. Therefore, for the purpose of simplifying the co-injection operation, a drug solution in which a single dose of drug solution is previously stored in a container provided with an injection unit such as a needle is used. Various containers have been proposed. As such a drug solution container, for example, in addition to a so-called prefilled syringe containing a drug solution in a syringe,

In the figure, reference numeral 8 denotes a chemical liquid container as a liquid container, which is integrally formed of plastic. A needle-like tube portion 12 is connected to the upper end side of the container main body 10 for accommodating the medicinal solution. It has been like that. Between the handle 16 formed in the middle of the needle-shaped tube 12 and the container body 10, thin reinforcing ribs 18 are integrally provided at target positions on both sides of the needle-shaped tube 12. Needle tube 12
3 has a shape like an acute angle cut-off, and in particular, the tip portion has a sharp triangular pyramid shape as shown in FIG. As shown in FIG. 3A, a thin portion 20 is formed at the distal end of the flow passage 14 in the needle-shaped tube portion 12, and the flow passage 14 is closed. A thin plate-like gripping piece 22 is integrally provided outside the thin-walled portion 20 at a distal end portion having a circular cross section as shown in FIG. The thin portion 20 is broken by moving it up and down or obliquely, and the flow passage 14 can be opened. The chemical liquid container is filled with a chemical liquid at the time of manufacturing, and the container main body 10 is configured to be able to discharge the content liquid by crushing it with a finger. The chemical solution container can be efficiently manufactured under aseptic conditions by a so-called blow-fill seal method in which the container is continuously formed, filled with the chemical solution, and sealed.

In the liquid medicine container of the embodiment constructed as described above, when the gripping piece 22 at the tip of the needle-like tube portion 12 is pinched and twisted with a finger or moved vertically, horizontally, or diagonally, the thin portion 20 is formed.
Is broken and the flow passage 14 is opened, so that the needle-shaped tubular portion 12
Is inserted into an infusion container or a side tube of an infusion circuit, and the container body 10 is pinched and pressed with a finger or the like, so that the content liquid (chemical solution) flows out into the infusion container or the side tube, and the infusion solution and the like. Be blended. When draining the contents liquid, put your thumb on the container body 1
It is convenient to hang it on the bottom of 0 and to hang another finger on the hand 16. In this way, a chemical solution that may be degraded if previously formulated can be easily blended each time it is used. As another means for opening the flow passage 14, an inclined fold is provided in the needle-like tube portion in advance, and when used, the needle tube portion is cut off to form a needle tip, and the front end of the flow passage is opened. Although it is conceivable that the distal end of the needle-shaped tube portion 12 is sharpened in advance in the present embodiment in comparison with such means, so that the sharpness at the time of use is good, and The opening of the flow passage 14 is particularly advantageous in that the thin portion 20 having a reduced thickness is broken by the gripping piece 22, so that it is easy to open and easy to use.
Further, since the chemical solution container of this embodiment is made of plastic, there is an advantage that incineration after use is easy.

The chemical solution container is made of plastic which is accepted as a medical container, like the conventional container of this kind.

As the polyethylene, a copolymer with an α-olefin such as propylene, 1-butene, 4-methyl-1-pentene and octene can be used in addition to a homopolymer of ethylene. Further, the copolymer may be linear or branched. Polyethylene can be appropriately selected from a wide range irrespective of high density or low density. As the polypropylene, a homopolymer or a copolymer with a small amount (generally, 10% by weight or less, preferably 5% by weight or less) of olefin such as ethylene and 1-butene can be used, and is widely used as a medical container. It is preferable to use a grade of the same grade. Furthermore, poly 1-butene and poly 4-methyl-
Polyolefins such as 1-pentene,
A cyclic olefin copolymer such as a tetracyclododecene copolymer and a styrene-based copolymer such as a styrene-ethylene-butylene-styrene block copolymer can be appropriately employed. The polyolefin may be used alone, or as a mixed resin or as a multilayer mold. If necessary, light-shielding properties can be imparted, or aluminum or silica can be evaporated.

For example, in addition to physiological saline, a solution such as distilled water, a vitamin solution, a trace element formulation solution, a fat emulsion solution, a calcium chloride solution for correction, etc., a blood coagulation inhibitor such as sodium heparin solution, pentobarbital, procaine hydrochloride Such as systemic or local anesthetics, sedatives such as calcium bromide, antipyretic analgesics and anti-inflammatory agents such as sodium salicylate, inotropics such as dopamine hydrochloride, peptic ulcers such as nicardipine hydrochloride, hormones such as sodium hydrocortisone phosphate, etc. A drug solution can be exemplified.

The container main body of the above embodiment is not limited to the shape shown in FIGS. 1 and 2, and various shapes and structures can be adopted as long as the contents can be discharged by crushing with a finger. The tip of the needle-shaped tube is not limited to a triangular pyramid as shown in FIG. 3B, but may have another sharp shape.
Further, the shape of the gripping piece is not limited to those shown in FIGS. 1 and 2 and may be various shapes. In short, any shape or structure that can be broken by applying force to the thin-walled portion may be used. Further, the container of the present embodiment is not limited to a chemical solution, and can be used for storing another liquid to be mixed at the time of use. For example,
It can also be used when accommodating a two-part adhesive to be mixed at the time of use. Although the embodiments of the present invention have been described above, the present invention is not limited to such embodiments at all, and it goes without saying that the present invention can be implemented in various modes without departing from the gist of the present invention.

[0010]

Since the present invention is configured as described above, the following effects can be obtained. According to the present invention, since the liquid container can be integrally formed of plastic, it is possible to employ a so-called blow-fill sealing method in which the molding of the container, the filling of the chemical solution, and the sealing process are continuously performed. The above operation can be performed efficiently under aseptic conditions. Further, since no metal is used, disposal by incineration after use is easy. Further, it is possible to inject the drug solution discharged from the needle-like tube portion into the infusion container or the side tube of the drip route, and to mix the drug solution at the time of infusion administration. In addition, the distal end of the needle-shaped tube portion is sharpened in advance and sharply formed, so that the sharpness at the time of use is good, and the opening of the flow passage is performed by moving a gripping piece of a thin portion having a reduced thickness. Because it is made to break, it is easy to open and use.
