である。The diameter of the protrusion 9.10 is slightly larger than the outer diameter of the small diameter part and approximately equal to the diameter of the through hole 3 of the small diameter part 2. As shown in FIG. 4(a), 11 is an inner cylinder made of a hard material, for example, hard plastic, and its outer periphery is slidable on the inner periphery of the outer cylinder l. Reference numeral 12 denotes a hole bored in the tip 3 of the inner cylinder 11. The diameter of the liquid hole 12 is
It is at least larger than the diameter d of the large diameter portion 6 of the needle holder 4. As shown in FIG. 6, 14 is a lid made of a soft material, for example a soft plastic, and has a U-shaped cross section. The diameter D1 of the liquid volume I4 is approximately equal to the diameter of the marking hole 12. Further, the wall thickness t of the distal end portion 13 of the inner cylinder 11 is approximately equal to, or at least greater than, the length T of the diameter portion 6 of the needle holder 4. That is, t≧T.
また、蓋１４の頭部には鍔１５を形成しである。Further, a flange 15 is formed at the head of the lid 14.

７は内筒１１の他端に取り付けた鍔である。The diameter of the collar 15 is slightly larger than the diameter of the lid 14. The head of the lid 14 is slightly curved outward. Therefore, when the lid 14 is inserted and fitted into the hole 2,
The head of the lid 14 is formed to be slightly convex with respect to the outer surface of the tip 13 of the inner cylinder 11. A syringe needle 16 is integrally fixed to the needle holder 4. When the needle holder 4 to which the injection needle 16 is integrally fixed is inserted into the through hole 3 of the outer cylinder 1 and fitted, the large diameter part 6 protrudes from the inner surface of the tip of the outer cylinder 1 because of the stepped part 7. It is fixed in this state. 1
7 is a collar attached to the other end of the inner cylinder 11.

It is sufficient that the groove 19 has at least a concave inner surface of the tip portion 13. The groove 19 is provided to prevent the tip of the injection needle from getting caught in the groove 19 and jumping out from the through hole 3 when the needle holder 4 is housed in the inner rR11. do not need. As shown in FIG. 7, 20 is a cap made of a soft material, for example, soft plastic. The cap 20 covers the injection needle as in the conventional case, and the base of the cap 20 is fitted to the outer periphery of the small diameter portion 2 of the outer cylinder 1. However, as shown in FIG. The outer diameter of the small diameter portion 21 may be formed to be approximately equal to the diameter of the through hole 3.
上記構成に基づいて本願発明の詳細な説明する。The present invention will be explained in detail based on the above configuration.

るようなことはないので、より安全である。After removing the cap 20 of the sterilized syringe and injecting a medicinal solution, for example, when the inner cylinder 7 is pressed, the medicinal solution is subjected to a predetermined pressure. At this time, the lid 14 is fitted into the hole 14 at the tip 13 of the inner cylinder 11 by the flange 15 so that it does not come off in the direction in which pressure is applied.
2 will never penetrate. In addition, the needle holder 4 is fitted into the through hole 3 of the outer cylinder 1 so that it does not come out in the direction in which pressure is applied, so the needle holder 4 does not come out within a predetermined pressure range. The chemical solution is discharged without any problems. When most of the drug solution has been discharged and the tip 13 of the inner mill approaches the narrow and small diameter section 2 of the outer mill, the large diameter section 6 of the needle holder 4 moves to the outer mill.
I! Since it protrudes from L by T, the chemical solution remaining near the tip is discharged and the hole 1 at the tip of inner 1111 is drained.
The soft cover 14 fitted into the hole 2 is moved into the hole 12 after its collar 15 is removed. Then, when the tip of the inner cylinder 11 comes into contact with the inner surface of the outer cylinder 1111 after moving by a distance T, the lid 14
is also held in the hole 12 at a position moved by T from its original position. Here, when the outer cylinder 1 is held in the hand and the tip of the injection needle 1G is forcefully applied to a predetermined object, the protrusion 9,10 of the needle holder 4 will be removed from the through hole 3. Further, the detached needle holder 4 enters the hole 12 of the inner tube 11, and the tip of the large diameter portion 6 hits the head of the lid 14 held there, and is pulled out of the hole 12 and exits. , is housed inside the inner cylinder 11, as shown in FIG. The injection needle 16 housed in the inner cylinder 11 together with the lid 14 is integrated with the needle holder 4, and since the diameters of the hole 12 and the large diameter part 6 are almost the same, the inner cylinder 11 is Although the hole 12 is in an open state, the injection needle 16 is not pulled out from the inside Ill. Here, if the cap 20 is further reversed and the small diameter part 21 of the cap 20 is inserted into the through hole 3 of the small diameter part 2 of the outer cylinder 1, it is necessary to make sure that the tip of the injection needle 16 enters the through hole 3. It's safer because it never happens.
