Therefore, in the fourteenth embodiment, similarly to the sixth embodiment, the pneumatic pressure generated by pushing the piston portion 5 through the pushing rod 7 instead of directly pushing out the chemical solution filled in the loading portion 10 by the piston portion 5 is used. The drug solution is pushed out by using.
- the partition wall 32 having the central hole 33 is provided in the cylinder 1, and the pressurized pneumatic force is applied to the chemical solution in the loading unit 10 through the central hole 33 by moving the piston 5 toward the ejection nozzle 11. Act It is like that.
- the bending angle of the cylinder 1 is not limited to the angle shown in FIG. For example, it can be bent at 45 °, 90 °, etc.
- FIG. 24 is a side view of a portable chemical solution ejection and injection device A according to Embodiment 15 of the present invention.
- Example 15 is basically the same as FIG. 23 except that the cylinder 1 is bent in an arc shape such that the front end portion and the rear end portion of the cylinder 1 are parallel to each other. It is the only point.
- Example 7-15 if the piston part 5 and the push rod 7 can be pushed into the ejection nozzle 11 by the force push rod 7, the two parts are separate. May be configured.
- a cylinder 1 having an ejection nozzle 11 (ejection hole) formed at the tip, a loading section 10 for accommodating a chemical and the like, and a loading section 10 inside the cylinder 1 are filled.
- a push rod 7 integrally formed with the piston part 5 and a cap 120 for closing the ejection nozzle 11. 20-100mm range is fine). Then, since the liquid medicine or the like filled in the loading section 10 is directly pushed out (spouted) by the piston 5, the liquid medicine is applied by using the pressurized air pressure generated by pushing the piston 5 through the push rod 7. Etc. are spouted.
- Cylinder 1 is a cylindrical member made of ABS resin or the like that is harmless even when licked by a child, and has a shape that gradually expands from the tip end surface (8 mm in diameter) and then has a constant diameter. (About 15 mm in diameter). Further, as shown in FIG. 25, a partition wall 32 having a center hole 33 is provided in the cylinder 1, and the loading portion 10 is moved through the center hole 33 by moving the piston portion 5 toward the ejection nozzle 11. The pressurized pneumatic force acts on the chemical solution inside. In this cylinder 1, the corner where the distal end surface and the outer peripheral surface intersect is cleanly chamfered to prevent pain when inserted into a human body.
- the piston portion 5 is formed of a thick disk made of ABS resin (or may be made of rubber), and two O-rings (sealing members) 116 are provided on the outer peripheral surface thereof at intervals. It is installed around. This screw As shown by the two-dot chain line in FIG. 25, the ton portion 5 can be moved inside the cylinder 11 while maintaining the outer peripheral airtight state by the O ring 116 provided around.
- the push rod 7 is made of ABS resin which is formed integrally with the piston part 5 (or may be separate body) with its axis aligned with the piston part 5.
- the diameter is set slightly smaller than the hole of the cylinder 1.
- the cap 120 is set in such a shape that the tip portion of the cylinder 1 is tightly covered.
- the shaft portion 40 projecting from the bottom surface is fitted into the ejection nozzle 11. It's so! /
- a plurality of the portable squirt injectors A can be carried in a bag.
- the cap 120 is attached to the cylinder 1, the shaft part 40 protruding from the bottom surface is fitted into the ejection nozzle 11! /, So that the chemical liquid flows out carelessly when carrying it. There is no. In other words, the drug solution does not flow out of the bag when carrying it.
- this portable squirting injector A can squirt the chemical solution from the squirting nozzle 11 by sandwiching the rear end portion of the cylinder 1 between the index finger and the middle finger and pushing the pushing rod 7 with the thumb. .
- cylinder 1 is inclined at an angle of about 30 °, so that cleaning with chemicals and injection of chemicals and the like are easy.
- FIG. 26 is a sectional view of a portable jet injector A according to Embodiment 17 of the present invention.

- Force As shown in FIG. 26, the push rod 7 is elastically moved according to the bent shape of the cylinder 1 at 30 °.
- This embodiment is different from the sixteenth embodiment only in that the push rod 7 is used to directly push out a chemical solution or the like from the jet nozzle 11.
- the push rod 7 can be formed by a rod-shaped body having a circular cross section made of, for example, elastic synthetic resin, rubber, elastomer, or the like, or a tubular body closed at both ends.
- FIG. 27 is a cross-sectional view of a portable squirt injector A of Embodiment 18 of the present invention.
