樹脂が好ましい。 The rod guide capsule 1 may have any external shape as long as it can be smoothly loaded into a solid drug administration device and can fit into the narrow end of the device. For example, even if 4 to 8 grooves are formed, only both ends of the straight part (indicated by the length d) of the guide capsule 1 are left, and the other parts are formed thinly to fit the hollow part. (It saves forming materials). The material for forming the guide capsule 1 is not particularly limited as long as it does not interact with the drug, but examples include transparent synthetic resins such as polyethylene, polypropylene, polystyrene, acrylonitrile butadiene styrene copolymer, and silicone. is preferred.

位に押し出す。 When using, for example, when using the rod guide capsule 1 containing the solid preparation D as shown in FIG. To,
The guide capsule 1, membrane 5 first, is loaded into the barrel 8 of the dosing device S with the plunger 7 removed.
Next, the plunger 7 is inserted into the barrel 8 with the small diameter rod 11 first, and the plunger is pushed forward. Then, the small-diameter rod 7 smoothly enters the capsule 1 through the rod guide path 2, pushes out the solid preparation D stored in the lumen 3 from the capsule 1, and inserts the injection needle 9 into the capsule 1.
The solid preparation D is extruded through the lumen of the body B to the implantation site.

ことがない。 The entry of the plunger 7 into the barrel 8 is stopped when the tip 12 of the large-diameter rod 10 hits the wall on the guide path 2 side of the capsule 1, but at this time, the tip 13 of the small-diameter rod 11 is just injected. Since the plunger 7 is formed so as to be located at an appropriate position on the cutting edge 14 of the needle 9, the tip 13 of the small diameter rod 11 is placed inside the body B.
If the solid preparation D
There is no possibility that the needle will remain in the injection needle 9 and the implantation will fail.
