When passing through the locking projection 19, the push rod 7 is very difficult or cannot be removed from the cylinder 1 due to the locking between the locking projection 14 ′ and the locking projection 19.

(About the medicine used for this portable injection device 10)
Examples of the drug used for the portable injection device 10 include a lubricant, a cleaning agent, and an anesthetic.

(How to use this portable injection device 10)
When this portable injection device 10 is used, a medical solution can be directly injected into the female genitals or human anus. How to use it will be described.

(1) First, the tip of cylinder-1 is inserted into the female genitals (in the vagina) or into the human anus. Since the tip portion of the cylinder 1 has a streamlined shape with a tapered tip, there is little pain during insertion. Thereafter, the cylinder-1 is sandwiched between the forefinger and the middle finger, and the push rod 7 is pushed in with the thumb. Then, the engagement between the annular protrusion 17 and the groove 6 is released, and the distal end portion of the push rod 7 is pushed out to the distal end side.

(2) When the push-in rod 7 is further pushed in from the state (1), the capsule 4 filled with the chemical solution or the like is pushed into the distal end side together with the piston portion 3, and the distal end side of the capsule 4 is cut by the cutting portion 12.

(3) When the push-in rod 7 is further pushed in from the state (2), the chemical liquid or the like is jetted (including jet jet) from the jet nozzle 11.

(4) When the state of the above (3) is continued and the expanded portion 9 enters the funnel-shaped portion 8 and the push-in of the push-in rod 7 is completed, most of the chemical liquid or the like filled in the capsule 4 is injected into the injection nozzle 11 At the same time, the locking projection 14 ′ passes through the locking projection 19. Then, due to the locking of the locking protrusion 14 ′ and the locking protrusion 19, the push-in bar 7 is very difficult to pull out from the cylinder 1 or does not come out. That is, the portable injection device 10 cannot be reused, so that no disease infection occurs and it is hygienic.

  The portable injection device 10 of the second embodiment has basically the same configuration as that of the first embodiment. However, as shown in FIGS. 4 and 5, a concave portion 5 ′ is provided in the central portion of the piston portion 5. Only the point is different.

  That is, in this portable injection / injection tool 10, as shown in FIGS. 4 and 5, the concave portion 5 ′ is formed in the center of the lower surface of the piston portion 5 and is thin.

  Therefore, in this portable injection / injection tool 10, once the piston portion 5 is pushed, it cannot be reused. This is because even if a needle or the like is pushed from the injection nozzle 11 and the piston portion 5 is pushed back, the central portion is thin, so that a hole is opened and the piston portion 5 cannot be pushed back.

  2, 4, and 5, since the hollow is formed from the upper end to the lower end of the push rod, the needle or the like thrust from the injection nozzle 11 passes through the piston portion 5 and then enters the hollow portion of the push rod. Therefore, the push rod 7 cannot be pushed out to the position before use with the needle or the like. That is, the portable injection device 10 cannot be reused, so that no disease infection occurs and it is hygienic.

  The portable injection / injection tool 10 of the third embodiment is basically the same as that of the first embodiment, but differs only in that the cutting portion 12 is not provided in the injection nozzle 11 as shown in FIG. ing.

  In this portable injection / injection tool 10, as shown in FIG. 6, the loading unit 15 is limited by the piston unit 5 and a predetermined volume is determined. Insert a certain amount into the cylinder 1 without sealing and fill it with the piston part 5 and the push-in rod 7, or insert another needle-injector with the space part 13 for filling. it can.

  As shown in FIG. 6, when the drug solution or the like is filled in the loading unit 15 as described above and the push bar 7 is brought into contact with the piston unit 5 and pushed in with a predetermined force, the drug solution or the like passes through the injection nozzle 11. Jetted.

  The portable injection / injection device 10 of the fourth embodiment is basically the same as the first embodiment, but is divided into an insertion portion 2 and a longitudinal portion 3 as shown in FIG. The first embodiment is different from the first embodiment in that the cylinder 1 is configured by integrating both of them by screw connection and the insertion portion 2 is formed in a cylindrical shape. In other words, in the fourth embodiment, the insertion portion 2 is constituted by the cap portion 20 formed in a cap shape, the female screw portion 18 is provided inside the rear end of the cap portion 20, and the male screw portion 24 is provided outside the front end of the longitudinal portion 3. Are formed.

  As shown in FIG. 7, the cap portion 20 is formed by closing a rear end portion with a membrane member 23, and an injection nozzle 21 extending at a predetermined depth is formed at the center of the tip and A loading portion 22 communicating with the injection nozzle 21 is formed. In addition, what is necessary is just to make it seal the outflow port of the injection nozzle 21 with an adhesive tape or a cap, after the loading part 22 is filled with a chemical | medical solution etc.

  As shown in FIG. 7, the longitudinal portion 3 is configured to position the piston portion 5 at the most distal end portion, and the other configuration is the same as that of the first embodiment.

  With the configuration as described above, it is possible to use the cap portion 20 having various shapes according to the preference, purpose of use, and the like. For example, in addition to a square (cylindrical) cap portion as shown in FIG. 7, the upper portion as shown in FIG. 8 is a hemispherical cap portion, and the upper portion as shown in FIG. 9 is a triangular shape (conical shape) when viewed from the front. The cap portion, the upper portion as shown in FIG. 10, can be a truncated cone-shaped cap portion.

  In this portable injection / injection tool 10, by pushing the push rod 7 toward the distal end side, the main brain member 23 can be broken to inject a chemical solution or the like via the injection nozzle 21 (including jet injection).

  FIG. 11 is a cross-sectional view of the portable injection / injection tool 10 immediately before the push rod 7 is moved to the tip side, and FIG. 12 is a diagram showing that the push rod 7 is pushed to the tip side and the piston portion 5 is moved to or near the injection nozzle 11. FIG. 13 shows a cross-sectional view in a state where the push rod 7 is pulled out from the state shown in FIG.

  Although the basic concept of the portable injection injector 10 of the fifth embodiment is the same as that of the first embodiment, as shown in FIGS. 11 to 13, the piston portion 5 is moved to the injection nozzle 11 or by the push rod 7. When the push rod 7 is pulled out after being pushed to the vicinity, the piston portion 5 remains at the injection nozzle 11 or in the vicinity thereof by being locked with the inner wall of the cylinder 1. For this reason, the piston part 5, the pushing rod 7, and the inner wall surface of the cylinder 1 are set as the following structures.

  As shown in FIG. 11, the piston portion 5 has a cap-like shape with a lower opening, and is provided with a locking projection 50 on the inner peripheral portion in the vicinity of the open portion and a locking projection 51 on the outer peripheral portion.

  As shown in FIG. 12, the inner wall surface of the cylinder 1 has a recess 100 into which a locking projection 51 is fitted when the piston portion 5 moves to the most advanced position (the injection nozzle 11 or the vicinity thereof) of the loading portion 15. Is provided.

  As shown in FIGS. 11 to 13, the push rod 7 is provided with a receiving tray portion 71 that receives the open end side of the piston portion 5 and a piston support portion 70 that extends to the receiving tray portion 71 on the tip side. The piston support portion 70 is composed of a head portion 72 on the distal end side and a neck portion 73 having a diameter smaller than the maximum diameter of the head portion 72.

  Here, as shown in FIG. 11, the cap-shaped piston portion 5 is covered from the head 72 to the neck 73, but the head 72 is forcedly inserted so as to push the locking projection 50 wide. is there. Therefore, the piston portion 5 is not inadvertently detached from the pushing rod 7. In this portable injection device 10, the locking force between the head 72 and the locking protrusion 50 is set smaller than the locking force between the locking protrusion 51 and the constituent wall of the recess 100.

  Therefore, in this portable injection injector 10, when the push rod 7 is pushed in as shown in FIG. 12, the piston portion 5 is pushed to the injection nozzle 11 or the vicinity thereof, and when the push rod 7 is pulled out as shown in FIG. The piston portion 5 remains at or near the injection nozzle 11. That is, since this portable injection device 10 cannot be reused, it does not cause disease infection and is hygienic.
