DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container / syringe that can be filled and stored in a syringe body in advance and used immediately after taking out of the package when used, and a method of assembling the same.

[0002]

2. Description of the Related Art A container / syringe in which an injection needle is previously assembled to a barrel of a syringe body can be used immediately after taking out of a packaging material without complicated operation in a hospital. It is very useful for reducing the work of nurses, and for this reason, many hospitals are adopting the container / syringe. However, in the conventional container / injection syringe, the injection needle is randomly assembled with respect to the syringe body, and is displayed on the finger hook of the finger grip attached to the rear end of the syringe body and on the outer periphery of the syringe body. Numerical values, letters,
In general, the positions of the three elements of the drug name, other important indications, and the blade surface of the injection needle in the circumferential direction of the syringe body do not coincide at all, and the finger hook of the finger grip and the aforementioned At present, there is no method of automatically checking the position of the scale or the like and the position of the blade surface of the injection needle, and assembling them mechanically so as to assemble the container / syringe.

In particular, when the barrel of the syringe body is of a luer lock type using a screw (a structure in which the syringe needle does not accidentally come out of the syringe body during injection), the syringe needle is connected to At the time of assembling by screwing into the cylinder tip, the part fixed by a fixed tightening force by the screw is the mounting position, and this mounting position forcibly sets a certain positional relationship in the circumferential direction of the syringe needle with respect to the syringe body. Therefore, it is not possible to finely adjust the blade surface position of the injection needle to correspond to the position of the finger grip, scale, etc. of the finger grip of the syringe body, and to match the positions.

[0004]

Therefore, in the hospital and clinic, the blade surface of the injection needle should be changed immediately before using the container / syringe.
It is customary to use the finger grip after fitting it to the finger hook or scale, etc., and because it is instructed as such, doctors and nurses need to use the blade surface and finger hook as described above. In the case of a container / syringe that does not match the scale, etc., immediately before use, the syringe needle assembled to the syringe body is temporarily turned in a direction to remove from the barrel of the syringe body, and a protector (guard) covering the syringe needle is provided. Check the direction of the blade surface of the injection needle from the outside, align the blade surface with the position of the finger hook of the finger grip, scale, etc., and then fix the injection needle firmly again to the syringe body tip before use There is a need to. This significantly impairs the convenience and safety of the combined use syringe, and improvement thereof has been strongly desired.

[0005] In particular, the tip of the barrel of the syringe body is
In the case of the lock type, the position of the screw, the tapered barrel portion (luer tip) of the barrel, and the thickness of the needle at the base of the needle of the syringe needle are combined from the relationship between the three. Since the position of the blade surface cannot be freely adjusted without knowing where the blade surface is fixed, even if the blade surface is oriented in a direction different from the scale or the like, the finger grip (flange) Or the inconvenience of injecting as it is, even if it does not match the position of the finger hook of the collar) must be tolerated. In some cases, there is a risk that the user may forget that the barrel tip is of a luer lock type and forcibly perform an operation such as aligning the blade surface of the injection needle with the scale of the syringe body.

At this time, the needle is forcibly rotated in order to adjust the blade surface position of the injection needle to the position of the scale or the like, thereby damaging the needle base or the screw of the luer lock type cylinder tip, or However, since the syringe needle was rotated in the direction opposite to the direction in which the screw was tightened to adjust the blade surface to the scale, etc., the fixation between the syringe needle and the barrel of the syringe body was loosened, and the gap between the barrel and the needle base was loosened. There is a problem that the preparation operation for injection becomes complicated, for example, there is a risk that the drug solution leaks from the container.
