Description

  The present invention relates to a drug solution injector, and in particular, a predetermined drug solution (enema agent, antipyretic agent, lubricant lotion (jelly), contraceptive agent, anesthetic agent) pre-loaded in a loading portion inside thereof is specified at a specific part of a person The present invention relates to a portable chemical injection device that can be injected into a female genital or human anus (including jet injection) to clean the site, and can be directly injected as needed.

  Today is a society where life is complicated and busy days continue. In order to spend such a modern age, many instruments that solve busy days of daily life have been developed and used.

  Nevertheless, development of simple instruments for female birth control and therapeutic drug insertion in the human body is still inadequate in relation to hygiene and specific parts of humans. In other words, hygiene around women's devices and vagina, insertion of contraceptive solutions, and cleanliness around the human anus are very important for disease prevention, but they are injected into female contraceptives and anus. The prescribed medicinal solution injection, such as enema, has been done directly by human hands. Such an operation is very cumbersome and not easy.

  As is well known, the female genitals, vagina, and human anus are very sensitive and sensitive areas that require considerable care. In particular, in the female genitals and vagina, further attention is required for the injection of a lubricant and a contraceptive for sexual intercourse, injection of a chemical solution for treatment and prevention of sexually transmitted diseases, and predetermined enema in the anus.

  However, the actual situation is that a simple and safe device for effectively washing the female genitals and anus and injecting a predetermined liquid medicine into the genitals and anus has not been developed yet. The reason is that there are various restrictions on the use of these devices, such as the ease of carrying them regardless of time and place.

  By the way, as this kind of chemical | medical solution injection device, it is disclosed by patent document 1, for example. This chemical injection device is equipped with a plastic cylinder having a lubricating liquid outlet formed at the tip, and a push-in rod provided in the cylinder is pushed toward the lubricating liquid outlet. The filled lubricating liquid is allowed to flow out from the lubricating liquid outlet. Therefore, when this is used, the lubricant can be easily applied to the female genitals.

However, since the above-described chemical solution injection device is not provided with a countermeasure against leakage of the lubricating liquid, there is a high possibility that the chemical liquid flows out from the lubricating liquid outlet when the portable liquid injection device is carried.

  The cylinder 1 has a cylindrical shape made of ABS resin or the like that is harmless to the human body (does not harm even if the child licks it). As shown in FIG. 1, the tip shape gradually increases in diameter from the tip surface. After that, the shape gradually decreases in diameter. Here, in the shape of the tip portion of the cylinder 1, the diameter of the tip surface is 8 mm, the length of the first area E1 that is the maximum diameter of 15 mm from the tip surface is 15 mm, and the length of the first area E1 is 12 mm from the end of the first area E1. The length of the second area E2 to be reduced in diameter is set to 20 mm and the total length is set to about 90 mm, and the corner where the tip surface and the outer peripheral surface intersect is cleanly chamfered.

  As shown in FIG. 1, the piston portion 2 is formed of a thick disc made of ABS resin (or rubber), and two O-rings 20 and 20 are provided at intervals on the outer peripheral surface thereof. It is installed around. As shown by a two-dot chain line in FIG. 1, the piston portion 2 can be moved in the cylinder 1 while maintaining an outer peripheral airtight state by O-rings 20, 20 provided around the piston portion 2.

  As shown in FIG. 1, the push-in rod 3 is made of ABS resin formed integrally with the piston portion 2 in a state where the piston portion 2 is aligned with the shaft center, and the diameter thereof is a cylinder. The diameter is set slightly smaller than one hole. When the push rod 3 is pushed to the maximum, the truncated cone portion 30 located at the rear end portion of the push rod 3 is fitted into the trumpet-like portion 12 located at the rear end portion of the cylinder 1 and is moved by the piston portion 2. Almost all of the chemical solution in the loading unit 10 is pushed out (injected) from the injection nozzle 11 to the outside.

As shown in FIG. 1, the cap 4 is set in such a shape that the first area E1 portion of the cylinder 1 is covered so as to be in close contact, and the shaft portion 40 protruding from the bottom surface injects when the cylinder 4 is mounted. It is inserted into the nozzle 11.
(About the excellent effect of this portable chemical injection device A)
Due to its size, this portable chemical injection injector A can be carried in a bag. The cap 4 is set in such a shape that the first area E1 portion of the cylinder 1 is covered so as to be in close contact, and the shaft portion 40 protruding from the bottom surface is fitted into the injection nozzle 11 when mounted on the cylinder 1. Therefore, the chemical solution does not flow out carelessly when carrying it. In other words, there is no possibility that the chemical liquid flows out when the mobile phone is carried and the inside of the bag is soiled.

  In addition, the portable chemical solution injection / injection tool A can inject the chemical solution from the injection nozzle 11 by pressing the push rod 3 with the thumb with the so-called index finger and middle finger sandwiching the rear end portion of the cylinder 1.
