Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drug applicator used for applying a drug to an affected area, and more particularly, to a drug applicator.
The present invention relates to a drug applicator capable of stably storing a drug in a state in which the drug is shielded from the outside when storing, and applying the drug in a sanitary, simple, and reliable manner to a diseased part when used.

[0002]

2. Description of the Related Art As an applicator for applying a drug to skin or the like,
Generally, cotton swabs and absorbent cotton are often used. Above all, swabs are hygienic because they can be operated without touching the application site, and are widely used.

By the way, when a swab or the like is impregnated with a drug solution and applied to the skin or the like, a swab and a container containing the drug solution are conventionally prepared, and each time the application is performed, the drug solution is dropped on the swab, or The swab was immersed in the drug solution to absorb the drug solution, and the swab having absorbed the drug solution was applied to the affected area. Therefore, not only the operation is complicated, but also a swab and a chemical solution storage container must be searched for each application. In addition, the swab and the remaining chemical solution may be contaminated, and there is a problem in hygiene. there were.

Therefore, there has been proposed a drug applicator in which a swab is impregnated with a drug solution in advance. For example, Japanese Utility Model Laid-Open No. 57-262
No. 47 discloses a cotton swab in which a chemical is impregnated in advance. However, it is necessary to prevent the chemical solution impregnated in the cotton ball from evaporating by the time of use. In the method of packaging only the cotton ball portion as described in the above publication, the cotton ball is completely wrapped along the curved surface of the axis of the cotton swab. It is difficult to seal, and it is difficult to completely suppress transpiration especially when the chemical is alcohol or the like. On the other hand, the method of hermetically packaging the entire body including the cotton swab has a problem in that the chemical impregnated in the cotton ball or the excess chemical liquid flows freely in the bag, and the cotton swab is contaminated. In addition, when carrying, the long shaft part may be bulky or the shaft rod may be broken.

Further, Japanese Patent Publication No. 4-12147 discloses that
There is disclosed a liquid application container in which a liquid is sealed and stored. The liquid agent application container is made of plastic and is formed of a rupturable thin portion at a breakable separation portion between the container body and the sealing member. However, in order to completely suppress the evaporation of the liquid agent, the plastic needs to have a certain thickness, which is inconsistent with a thin portion that can be broken, and it is not easy to balance the two. In particular, it is particularly difficult in the case of a highly volatile liquid containing alcohol. Further, from the viewpoint of usability, it is necessary to design the break portion to break with a relatively weak force, and there is a possibility that an unexpected force may be applied to the thin portion to cause breakage of the thin portion.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned drawbacks of the prior art, and not only to prevent the leakage of the medicine during storage and transportation, but also to contaminate the medicine and damage the application part of the medicine. An object of the present invention is to provide a medicine applicator that can be carried without being bulky, and can be used in a sanitary and simple manner.

[0007]

According to a first aspect of the present invention, there is provided a medicine applicator comprising at least a rod-shaped or tubular medicine applying member, a cap of the medicine applying member, and a medicine. The medicine is stored in a sealed space formed by joining the medicine applying member and the cap of the medicine applying member, and the cap is provided with an opening means.

According to a second aspect of the present invention, there is provided the drug applicator according to the first aspect, wherein the cap opening means is a cap opening part detachable from the cap.

Hereinafter, the present invention will be described in detail. (Drug application member) The shape of the drug application member used in the present invention is substantially rod-like or substantially tubular, but the diameter may not be the same over the entire length, and the cross-sectional shape may be the same over the entire length. It does not have to be. That is, a combination of two or more different diameters or different cross-sectional shapes may be used, or a main rod-like or tubular body may be joined or provided with a projection or a modification.

[0010] The drug application member has at least a grip portion and an application portion. The grip portion has a shape and a size that are easy to operate when applying the medicine. For example, the shape of the gripping portion includes a cylinder or a prism. For example, in the case of a cylinder, the diameter is about 1 to 20 mm, and the length is 5 to 50 mm.
The degree is preferably, but not particularly limited. The grip may be provided with anti-slip such as unevenness as necessary.

The application section is a section for holding a predetermined amount of a drug and applying it to the skin or the like. However, during application, the application surface that comes into contact with the surface to be applied such as the skin is mainly the tip surface of the application section. The tip surface of the application section may be configured so that the application section has a function of transferring the drug adhered to the surface as it is in contact with the drug to the skin as it is, but the surface is moderately roughened or uneven. Preferably, the surface area is increased by increasing the surface area, or if the drug is a liquid, the surface tension is used to increase the drug holding amount. Further, an absorbent material for absorbing the medicine may be provided at the tip portion of the application section, and the absorbent material may be brought into contact with the surface to be coated and applied. As the absorbent, for example, a porous material such as a natural material such as cotton, a fiber aggregate such as a synthetic resin, or a sponge body can be used, but is not limited thereto.

The material of the drug application member is not particularly limited, but various synthetic resins and metals can be used. For example, synthetic resins include polyolefin resins such as polyethylene and polypropylene; polyvinyl chloride; polyacetal resins such as polyoxymethylene; acrylic resins such as polymethyl methacrylate; polyethylene terephthalate; polycarbonate; polymethylpentene; Styrene resins such as styrene copolymer (AS resin) and acrylonitrile-butadiene-styrene copolymer (ABS resin).

(Cap of Drug Application Member) The shape of the cap of the drug application member used in the present invention is not particularly limited, but the body portion is, for example, a substantially cylindrical shape with a bottom; Substantially triangular, substantially quadrangular, substantially polygonal; substantially spherical. The cap is provided with an opening means (described later) to easily open the cap. A medicine is stored in the cap, and the cap is joined to the medicine application member, whereby the medicine is hermetically stored in a space formed by the medicine application member and the cap of the medicine application member. Since the medicine is stored in the space, it is not necessary to newly supply the medicine to the medicine application member at the time of use. In the medicine applicator of the present invention, the cap of the medicine application member is removed, and the medicine can be applied to the skin or the like using the application section of the medicine application member. In addition, the cap of the drug application member also has a protective function of preventing contamination and damage of the application portion of the drug application member.

The material of the cap of the drug application member is not particularly limited, and for example, various synthetic resins can be used. Examples of the synthetic resin include polyolefin resins such as polyethylene and polypropylene; polyvinyl chloride; polyvinylidene chloride; polymethylpentene; ethylene-vinyl acetate copolymer; polyacetal resins such as polyoxymethylene; acrylic resins such as polymethyl methacrylate. resin;
Polyethylene terephthalate; polycarbonate; polystyrene, acrylonitrile-styrene copolymer (AS
Styrene-based synthetic resins such as acrylonitrile-butadiene-styrene copolymer (ABS resin); various elastomers; and rubber. Of these, relatively soft ones such as polyethylene, polypropylene, and polymethylpentene are particularly preferred. The cap is more preferably colorless and transparent in order to confirm the presence or absence of contamination or contamination of the medicine contained in the cap, the filling amount, and the like.

(Joining of the medicine applying member and the cap of the medicine applying member) The joining method of the medicine applying member and the cap of the medicine applying member uses any method such as fitting by tapered surfaces, screws, fitting, and bonding. Can be. It is preferable that the bonding between the drug application member and the cap be sufficiently airtight so as to block the drug from the outside during storage and to prevent the drug from evaporating to the outside. For example, there is a method of fitting tapered surfaces such as fitting of an injection cylinder and a syringe needle, and a method using screws using packing. As another preferable example, a method in which fixing with a screw or fixing with a luer lock is further combined with taper fitting may be mentioned. Generally, in the case of the taper fitting, the fitting is often strong.

(Cap Opening Means) When the cap of the medicine applying member and the cap of the medicine applying member are strongly joined to obtain airtightness, a considerable force is often required when opening the cap. The cap opening means in the present invention refers to means for easily opening the cap, and means for opening the cap more easily than when opening the cap with only the body of the cap. There is no particular limitation as long as it exists. As means for opening the cap, for example, there is a means in which the grip portion at the time of opening the cap has an outer diameter larger than the body of the cap. Examples of the shape of the grip portion include, but are not limited to, a columnar shape and a prismatic shape having an arbitrary thickness. Further, the holding portion may have a hollow portion. It is preferable that a non-slip is provided on the outer peripheral surface of the grip portion. Alternatively, a cap may be provided with a blade shape radially from the body of the cap, and the cap may be gripped and opened to facilitate opening.

The opening means may be provided integrally with the body of the cap.
A cap opening part as a detachable separate part may be used. The cap opening part is not particularly limited as long as it can be easily opened by being attached to the cap, and includes, for example, a part having a larger diameter than the body of the cap. As described above, a cylindrical shape, a prismatic shape, a radial blade shape and the like can be mentioned. The cap opening part is provided with a part (for example, a hollow part for fitting) related to the attachment to the cap body.

The advantages of the detachable cap opening part are as follows, for example. As described above, since the medicine stored in the cap is checked from the outside of the cap after foreign substances are mixed or contaminated, the filling amount, and the like after being stored in the cap, the cap body and the gripping portion at the time of opening the cap (opening means) ) Must be considered so as not to hinder the inspection of the stored medicine.
Since the cap opening part is detachable, it can be attached to the cap body after the inspection, and does not hinder the inspection of the stored medicine. The cap opening part may be attached from the time of product shipment, or may be attached together with an assembly of other parts and attached when used.
In addition, since it is detachable, the opened part can be reused.

The method for mounting and fixing the cap opening part to the cap is not particularly limited, and examples thereof include a fitting method by fitting. At this time, it is necessary to adjust the shape of the fitting portion between the cap and the cap opening part so that the cap opening part has a male-female relationship so that the cap opening part does not run idle after mounting. For example, it is possible to provide a convex portion on the cap and a concave portion on the cap opening part. As the mounting and fixing method, not only fitting but also screw-type fixing, welding by heat, high frequency, ultrasonic wave, or the like, or bonding by a solvent or an adhesive can be used.

The material of the cap holding portion (opening means) and the cap opening part is not particularly limited, and the above-mentioned materials usable for the cap can be used. The same material as the cap or a different material may be used. For example,
Various synthetic resins, metals, inorganic materials such as ceramics, wood and paper can be used. Examples of the synthetic resin include polyolefin resins such as polyethylene and polypropylene; polyvinyl chloride; ethylene-vinyl acetate copolymer; polyacetal resins such as polyoxymethylene; acrylic resins such as polymethyl methacrylate; polyethylene terephthalate; Polymethylpentene;
Styrene-based resins such as polystyrene, acrylonitrile-styrene copolymer (AS resin), and acrylonitrile-butadiene-styrene copolymer (ABS resin) are exemplified. Further, various elastomers and rubbers may be used.

(Drugs) The drugs used in the present invention are not particularly limited, and all drugs suitable for application to the skin or the like can be used. Examples of the drug include a drug solution, lotion, ointment, cream and the like. Further, the chemical solution may be an aqueous solution of a main component exhibiting a medicinal effect or the like, or may be a solution in another solvent. Further, the chemical solution may be a dispersion instead of a solution. The chemical may be aqueous or oily. There is no particular limitation on the main component showing medicinal properties, etc., for example, disinfectants, scratching drugs, anti-itch drugs, athlete's foot drugs, testing / diagnostic drugs, and the like, and use of a washing solution or a cosmetic solution, etc. Is also possible.
