Description

[Detailed description of the invention] (Field of industrial application) This invention is used to protect wooden houses etc. from damage such as rotting fungi and termites. This invention relates to a liquid drug injector that can inject liquid medicine.

(Prior Art) In general, in wooden houses, care must be taken to prevent rot and insects in order to improve durability.

Conventionally, as a preventive measure against rot and insects for wooden houses,
In particular, it is common practice to apply or inject chemicals such as preservatives and insect repellents to foundations, floor bundles, etc. that are susceptible to rotting fungi, termites, and the like. In addition, chemicals are regularly sprayed under the floor to prevent termites from harming the floor.

By the way, even if antiseptic and insect repellent measures are taken as described above, the antiseptic and insect repellent effects will fade after a certain period of time, so it is necessary to apply or spray the chemical on the foundation etc. again.

However, there is a problem in that it is extremely difficult to apply or spray chemicals to foundations under floors, floor bundles, etc., and it is not possible to apply or spray chemicals well and reliably. Furthermore, even if the temporary chemical is successfully applied or dispersed to the base, etc., the chemical adheres only to the surface of the base, etc., and there is often a problem that the base, etc. is damaged from within.

(Problems to be solved by the invention) The present invention was created to solve the above problems, and its purpose is to effectively and reliably prevent rot and insects in wooden houses over a long period of time. To provide drug injectors.

(Means for Solving the Problems) The drug injector of the present invention has a plurality of small holes in the peripheral wall, and includes a cylindrical injection part that is inserted into a hole drilled in the foundation of a wooden house, etc. a syringe main body consisting of a storage part connected to the injection part and capable of storing a medical solution such as a preservative or an insect repellent and supplying it to the injection part; filled into the injection part and capable of impregnating the medical solution; It is characterized by being composed of an impregnating material.

(Function) When applying rot protection or insect repellent to a wooden house, a hole is drilled in a place susceptible to damage from rotting fungi and termites, such as the foundation, to insert the injection part of the syringe body. Insert the injection part into the hole, and pour an appropriate amount of medicinal solution such as antiseptic and insect repellent into the storage part of the syringe body.
Then, after the chemical solution in the reservoir is impregnated with the impregnating material in the injection part, it gradually oozes out from the small holes in the injection part to the outer circumferential surface of the injection part, and gradually penetrates into the foundation etc. due to the capillary action of the wood. . As a result, antiseptic and insect repellent effects can be obtained.

Moreover, when the medicinal solution in the reservoir runs out, a new medicinal solution is put into the reservoir.

By doing so, excellent antiseptic and insect repellent effects can be obtained over a long period of time.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

1 to 3 show a chemical liquid injector according to an embodiment of the present invention, and the chemical liquid injector is composed of a syringe main body 1 and an impregnating material 2. As shown in FIG.

The syringe main body 1 is formed into an L-shaped pipe shape with one end closed with vinyl chloride resin, and includes an injection part 4 having a plurality of small holes 3 bored at equal intervals in the peripheral wall, and the injection part. 4, which stores a chemical solution 5 such as an antiseptic or insect repellent and transfers it to the injection part 4.
It consists of a storage section 6 that can be supplied to.

The impregnating material 2 is filled into the injection part 4 of the syringe main body 1 and impregnated with a chemical solution 5 such as a preservative.
In this embodiment, asbestos is used as the impregnating material 2.

Incidentally, the outer diameter of the injection part 4 of the syringe main body 1 is approximately
The length of the injection part 4 is about 80 mm to about 15 mm to 30 mm.
Each is set to about 130mm. Also, injection part 4
The diameter of the small hole 3 is set to such an extent that the chemical solution 5 impregnated in the impregnating material 2 gradually oozes out from the small hole 3.

Therefore, when using the chemical injector to protect a wooden house from damage caused by rotting fungi and termites, the first step is to apply it to the foundation 8 near the floor bundle 7, which is likely to be damaged by rotting fungi and termites. A hole 9 for inserting the injection part 4 of the syringe main body 1 is bored horizontally. The inner diameter of this hole 9 is
It is set to be approximately the same as the outer diameter of the injection part 4.

Next, insert the injection part 4 of the syringe main body 1 into the hole 9 so that the reservoir part 6 faces upward.

Then, a suitable amount of a medicinal solution 5 such as a preservative or an insect repellent is put into the reservoir 6 of the syringe main body 1. This chemical solution 5 uses creosote oil, pentachlorophenol, or the like. Incidentally, the syringe main body 1 is protected by a protective case 10 to prevent foreign matter, dust, etc. from entering the inside.

The chemical solution 5 in the storage section 6 is mixed with the impregnating material 2 in the injection section 4.
After being impregnated with water, it gradually oozes out from the small hole 3 of the injection part 4 to the outer peripheral surface of the injection part 4, and gradually penetrates into the base 8 due to the capillary action of the wood. As a result, antiseptic and insect repellent effects can be obtained over a long period of time.

Note that if 0.5 of the chemical solution 5 is placed in the reservoir 6, it will be consumed in about 2 years.

On the other hand, if the drug solution 5 in the syringe main body 1 runs out,
A new chemical solution 5 is injected into the reservoir 6.

In the above embodiment, the injection part 4 and the reservoir part 6 of the syringe main body 1 were formed with the same diameter, but in other embodiments, only the reservoir part 6 was formed as shown in FIG. It may be formed to have a large diameter so that a large amount of the chemical solution 5 can be stored.

Further, the shape of the injection part main body 1 is not limited to that of the above embodiment, and includes an injection part 4 having a plurality of small holes 3 and a reservoir connected to the injection part 4 that can store the medicinal solution 5. The shape is arbitrary as long as it includes the section 6.

Furthermore, the material of the syringe main body 1 is not limited to that of the above embodiment.

In addition, in the above embodiment, asbestos was used as the impregnating material 2, but in other embodiments, cotton, sponge, etc. may be used as the impregnating material 2.

(Effects of the invention) The chemical liquid injector of the present invention not only fills the injection part of the syringe body with an impregnating material, but also stores a chemical liquid such as a preservative in the storage part of the syringe body and impregnates the impregnating material with it. The chemical solution in the impregnating material is configured so that it gradually oozes outward from the small hole in the injection part, so if the injection part is inserted into a hole drilled in the foundation of a wooden house, the chemical solution will be absorbed into the foundation, etc. It gradually penetrates into the interior by capillary action, and good and reliable antiseptic and insect repellent effects can be obtained over a long period of time.

In addition, when the antiseptic and insect repellent effects wear off, it is sufficient to simply inject the chemical solution into the storage part of the syringe body, and there is no need to go under the floor and apply or spray the chemical on the foundation etc. as in the past. Therefore, it is possible to perform antiseptic and insect repellent very simply and easily.

Furthermore, since the chemical solution can be injected into the inside of the base etc., even better antiseptic and insect repellent effects can be obtained.
