[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a disinfection and therapeutic drug applicator, and in particular, a convenient and portable drug applicator that can be quickly applied to the disinfection treatment of external wounds and the like. Regarding.

[Prior Art] Conventionally, to disinfect and treat external wounds such as abrasions and cuts, it has been widely used to soak absorbent cotton supported by tweezers in a medicinal solution and apply it to the affected area.

It is difficult to carry such tweezers, absorbent cotton, and medical solutions at all times, and when a wound is sustained outdoors, disinfection and treatment are delayed, often causing the wound to fester. In addition, tweezers and absorbent cotton must be sterile when used, and tweezers must be sterilized after use and, like unused absorbent cotton, must remain sterile until the next use. It is almost impossible to maintain tweezers in a safe condition at home.

Therefore, there is a need for a disinfectant treatment instrument that is easy to maintain in a sterile state and is easy to use, but a simple one has not been available so far.

[Problems to be Solved by the Invention] An object of the present invention is to provide a portable drug application tool for disinfecting external wounds, which does not cause suppuration due to delayed treatment.
Another object of the present invention is to provide a drug application tool that solves the difficult problem of maintaining tweezers and absorbent cotton in a sterile state.

[Structure of the Invention] [Means for Solving the Problems] The present invention includes a cylindrical container body having a coating member at one end and an open end, and an elastic gasket at the tip, and a container body having an elastic gasket at the other end. A chemical liquid applicator comprising a pusher having a finger rest and inserted into the container body, and a chemical liquid stored between the applicator member in the container body and the gasket, the applicator member is a chemical liquid application tool characterized by being made of a porous body or a long fiber bundle capable of filtering the chemical liquid. The container body has an elastic stopper that is slidable inside the container body between the gasket and the application member,
Preferably, the chemical solution is sealed and stored between the elastic stopper and the gasket, and the inner diameter of the container body on the application member side of the elastic stopper is larger than the diameter of the elastic stopper. Further, the container main body has a cap portion that covers the application member, so that the application member can be shielded from the outside. Furthermore, the container body and the cap are integrated at a breakable thin part,
The application member can be configured to be exposed when the two are separated.

[Function] The chemical liquid applicator according to the present invention is easy to use. Before use, the cap covering the application member can be removed, the pusher can be pressed, and the chemical liquid sealing stopper can be removed. It is infiltrated into the application member. Therefore, with the device of the present invention, the amount of liquid medicine can be adjusted by the pressing force of the pusher, and the liquid medicine can be dripped as necessary, such as when washing away foreign matter adhering to the affected area. .

The chemical liquid applicator (stick) according to the present invention includes:
A plastic outer cylinder with a hollow part, an elastic stopper attached to the opening of the outer cylinder, and a pusher attached to the other end of the plastic outer cylinder. It has an elastic gasket, and a chemical solution is sealed in the hollow part of the outer cylinder between the elastic stopper and the elastic gasket. Therefore, the pillar and gasket are in close contact with the inner surface of the outer cylinder, making the chemical liquid airtight from the outside. Further, in the chemical liquid applicator of the present invention, a hollow sheathing member is further provided at the end of the outer cylinder on the side where the elastic plug is attached, and an applicator is provided at the distal end of the sheathing member. A cap is further provided on the outside of the applicator to isolate the applicator from the outside. As described above, in the chemical liquid applicator of the present invention, the chemical liquid can be completely isolated from the outside in the container, maintained in a sterile state, and prevented from leaking or evaporating to the outside.

Pushers can usually be manufactured from plastic.
The shape may be one that has the same function as a conventional regular syringe, such as a straight rod, an L-shaped pusher that has exactly the same function, or any other structure that has the same function. It may have a shape like this.

When using this L-shaped pusher, a slit is provided in a part of the side of the outer cylinder (container) at the end opposite to the gasket provided at the tip, and the protruding L-shaped tip is exposed to the outside. By using a side slide switch type, the overall length of the pusher can be shortened, and the chemical liquid applicator of the present invention can be made more compact.

In the chemical application tool of the present invention, the tip of the outer cylinder further includes:
The device has an outer sheathing member having an applicator at its tip, and applies the medicinal liquid to the skin of a human body by means of the applicator member soaked with the medicinal liquid that flows out when the pusher is pressed. For this application member and its surrounding area,
Furthermore, a cap member is provided to isolate it from the outside. Thereby, the application member of the present invention has a structure that can be easily kept in a sterile state.

The chemical solution applicator of the present invention can be sterilized by a well-known sterilization method during or after its manufacture.

For example, plastics such as polyethylene, polypropylene, polystyrene, and polyethylene terephthalate can be used as the chemical application tool of the present invention.

These synthetic resins can be molded by injection molding, extrusion molding, blow molding, vacuum molding, or the like.

The drug solution applicator according to the present invention is not limited to a tubular shape, but a tubular one is suitable and preferred from the viewpoint of molding technology and the like.

[Example] Next, the chemical liquid applicator of the present invention will be explained using the following specific example, but the present invention is not limited to the following explanation.

FIG. 1 shows a partially sectional front view of the structure of a chemical liquid applicator according to the present invention.

1 is an application member, 2 is an elastic stopper, e.g., a rubber stopper, 3 is a chemical liquid, 4 is an elastic gasket, e.g., a rubber gasket, 5 is a pusher, and 7 is a hollow cylindrical member. In the container, 7a is the outer cover.
7 and 7a constitute a container body. Application member 1
is formed from a porous material or a long fiber bundle. The drug infiltrates and can be supplied to the affected area. The elastic stopper 2 is a hollow cylindrical container 7
It is pushed into the area that extends from the wide hollow part to the narrow hollow part and is tightly fixed by the elastic force of the elastic body. The chemical solution 3 is stored in a space between the fixed elastic stopper 2 and the elastic gasket 4 at the tip of the pusher 5. The pusher 5 has a pushing part 6 at the end opposite to the gasket 4. Further, in front of the fixed tip of the elastic stopper 2 of the hollow cylindrical container 7, there is an outer cover 7a, and the applicator 1 is attached to the end of the outer cover 7a. The outer cover 7a is hollow, and forms a space between the elastic plug 2 and the application member 1, which are tightly fixed. The outer cover 7a is provided with the applicator 1 at its end, and a cap (not shown) can be attached to the outer cover 7a to protect these members from the outside. The cap has a shape that covers the outer cover 7a and the application member 1, and is made of plastic.

FIG. 2 is a partially sectional view showing how the chemical liquid applicator shown in FIG. 1 is used.

That is, by pushing the end 6 of the pusher 5 of this chemical liquid applicator in the direction of the arrow, pressure is applied to the chemical liquid 3 with the elastic gasket 4. The medicinal liquid 3 under pressure applies its pressure to the elastic stopper 2. When this pressure exceeds the contact resistance of the elastic plug 2,
The elastic stopper 2 is removed from the opening of the cylindrical container 7, and the chemical solution 3 flows out together with the elastic stopper 2 into the hollow part of the outer cover 8. The drug solution 3 fills the hollow part of the outer cover 7a, and the application member 1.

By adjusting the force with which the pusher 5 is pressed, the amount of the chemical solution flowing out can be adjusted, and the amount of the chemical solution supplied to the application member 1 can be adjusted as appropriate. That is, for normal application of the affected area, the pushing force on the pusher 5 is small and the affected area cannot be applied directly, but when dripping the medicinal solution from the applicator 1, it is pressed strongly and the medicinal solution can be supplied from the applicator 1 as appropriate. .

FIG. 3 is a partial cross-sectional view showing the structure of the present invention, particularly the chemical liquid applicator having an improved shape of the pusher.

That is, it has a structure in which the pusher is L-shaped and the chemical liquid applicator can be made compact. pusher 5
