Description

[Technical field]

[0001] The present invention relates to a drug applicator, a drug application kit, and a pressure tool for the drug applicator, which apply drugs or cosmetics such as anti-inflammatory agents or sunscreens to the back of the human body, and in particular to a drug applicator, a drug application kit, and a pressure tool for the drug applicator that are suitable for the person to apply the drug or cosmetics themselves. [Background technology]

[0002] Many aids have been proposed for applying ointments, medicinal liquids, or liquid cosmetics such as sunscreen to areas that are difficult for the recipient to reach, such as the back, or for applying compresses to those areas. Many of these aids have an application part or application part formed on the so-called backscratcher part for applying the liquid.

[0003] An example of a conventional drug applicator is described in Patent Document 1. This publication provides a drug applicator that allows a user to apply drugs to, disinfect, wipe away pus, and wipe away blood on hard-to-reach areas such as the back. That is, the drug applicator has a handle at one end of a curved arm and a drug applicator at the other end, and is provided with a clamping stopper plate on the top of the drug applicator. When using, tissue paper, gauze, absorbent cotton, etc. is placed under the drug applicator, folded at the fold line, and wrapped around the drug applicator, and both ends are folded over the top of the drug applicator. Then, the clamping stopper plate is placed over the drug applicator and fixed with an engaging claw.

[0004] An example of a conventional household medical aid that allows for easy application and removal of medicinal patches to affected areas of the back is described in Patent Document 2. In the medical aid described in this publication, the medicinal patch fixing device has an integrated structure in which the upper part of a curved pressing plate with a removal part at the bottom and the upper part of a clamping plate with a claw are connected by a spring-equipped shaft. A support arm with a grip part is connected by a support arm attachment part, and the structure allows for attachment and detachment and angle adjustment. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Utility Model Registration No. 3176802 [Patent Document 2] JP 2001-129098 A Summary of the Invention [Problem to be solved by the invention]

[0006] In the conventional applicator described in Patent Document 1, an applicator is provided at the end of the backscratcher-shaped applicator, instead of the scratching part of the backscratcher. The applicator is then soaked in or applied with a drug, and transferred to the skin of the person to be applied with the drug. This configuration allows the person to feel as if they are applying the drug with their own hands, even to areas of the back that the person cannot reach with their own hands.

[0007] In the applicator described in Patent Document 1, an elliptical drug applicator is formed at the tip of a curved arm, and tissue paper, cotton, gauze, etc. (hereinafter also referred to as treatment product) is arranged to encase the drug applicator, and a clamping stopper plate that rotates at the base of the drug applicator is rotated to press against the tissue paper, cotton, gauze, etc. (hereinafter also referred to as treatment product) and fixed with an engaging claw provided at the end of the stopper plate. This applicator can securely hold treatment products such as tissue paper, cotton, gauze, etc., but the proportion or effective area of ​​the part used for application or wiping out of the entire treatment product is reduced. Standard products such as cut cotton and cotton puffs, which are typical examples of treatment products, are about 5 cm square, and when folded for clamping, the effective area available for application or wiping is drastically reduced, and only a small part of the skin can be treated (applied or wiped off) at a time, which lengthens the application time and increases the part that is not used for treatment and is discarded.

[0008] Patent Document 2 discloses that a clip with a claw is used to grasp the patch and carry it to the application section, and when the application position is reached, the clip stops grasping and a pressure plate is used to press and apply the patch. The medical aid described in Patent Document 2 is primarily intended to apply or remove patches, and does not take into consideration the need to securely hold the cut cotton or cotton puffs or other treatment items to apply medicines while maximizing the effective area used for applying medicines.

[0009] The present invention has been made in consideration of the above-mentioned conventional drawbacks of applicators that allow a user to apply a medicinal liquid to the back by himself / herself, and its object is to provide a medicinal liquid applicator in which the scraping handle of a backscratcher with an arm is replaced with an applicator for applying the medicinal liquid, which is capable of detachably holding disposable treatment products used for application and which has an effective area used for applying the treatment products as large as possible. [Means for solving the problem]

[0010] The feature of the present invention for achieving the above-mentioned object is that, in a drug applicator comprising an arm extending in a longitudinal direction with one end side used for gripping, and a base portion arranged on the arm approximately parallel to the longitudinal direction of the arm, a pair of pressing tools for removably holding an applicator member on the base portion are provided, the pair of pressing tools are provided with repulsive devices for generating a pressing force to bring the applicator member into contact with the base portion, and the drug applicator is provided with a finger rest portion for assisting operation of the pressing tools or for operating the pressing tools.

[0011] In the present invention, "an arm having one end used for gripping" can also be rephrased as, for example, "an arm having a gripping portion formed on one end". In addition, "substantially parallel" refers not only to a state in which the longitudinal direction of the arm and the base are completely parallel with no angle between them, but also to a state in which they are roughly parallel with a small angle between them. Specifically, for example, it refers to a state in which the longitudinal direction of the arm and the base are completely or roughly parallel with an angle of about 0° to 7° between them. The application member may be disposed, for example, so as to cover at least a portion of the bottom surface of the base. Moreover, the term "applicator member" includes any member capable of holding an application agent such as medicine or cosmetics on or inside the member and capable of being placed on a base. For example, materials such as cotton, cloth, nonwoven fabric, and paper made of natural or chemical fibers are all included, and more specifically, cotton puffs, absorbent cotton such as cut cotton, tissue paper, gauze, and the like are all included. In addition, both disposable and non-disposable materials are included. The term "applicator member" can also be rephrased as, for example, "treatment product." In addition, "a repulsive device that generates a pressing force to bring the application member into contact with the base portion" more specifically implies, for example, "a repulsive device that brings the application member into contact with the base portion and generates a pressing force of the application member against the base portion." The "pressing tool" also includes, for example, a clamping means such as a clip that can hold the application member by clamping it between the base portion and the pressing tool. In addition, "to assist the operation of the pressing tools" refers to using the finger rests as an auxiliary to assist the opening and closing operation of the pressing tools when the opening and closing position of the pressing tools cannot be stably controlled even if the user tries to pinch the knobs of the pair of pressing tools with his or her fingers, and "to operate the pressing tools" refers to using the pressing tools only in the same manner as described in the "Mode for carrying out the invention" below, without pinching the knobs of the pair of pressing tools from the beginning. In other words, it refers to using the finger rests arranged corresponding to each pressing tool without fail when opening and closing the pressing tools.

[0012] Therefore, the above-mentioned features of the present invention can also be rephrased as follows, for example. In a drug applicator comprising an arm extending in the longitudinal direction and having a gripping portion formed on one end thereof, and a base portion arranged on the arm so as to be completely or approximately parallel to the longitudinal direction of the arm, a pair of clips are provided for removably holding disposable or non-disposable treatment products arranged to cover at least a portion of the bottom side of the base portion, the pair of clips abutting the treatment products against the base portion and comprising a repulsion device for generating a pressing force of the treatment products against the base portion, and the drug applicator is provided with a finger rest for assisting in the operation of the clips or for operating the clips.

[0013] In the above-mentioned feature of the present invention, the base may be disposed at approximately the center of the arm, and both ends of the arm may be used as portions to be grasped, i.e., gripping portions. The base may be disposed at or near the other end of the arm, and a sub-arm (also referred to as an "auxiliary arm" in this specification) that extends the arm may be detachably attached to the other end of the arm, and a second gripping portion may be formed at the end of the sub-arm (i.e., the end of the sub-arm may also be used for grasping).

[0014] In the above-mentioned features, each end of the pair of pressing tools (clips, etc.) may be formed as a knob, and the repulsion tool may be a coil spring (such as a spring called a kick spring, torsion spring, twisted coil spring, etc.) wound around an axis provided on the arm, one end of which abuts against the rear side of the knob of each pressing tool (clip, etc.) and the other end of which is fixed to the arm, or the repulsion tool may be a leaf spring whose both ends are fixed to the rear side of the knob of each pressing tool (clip, etc.). Furthermore, the base may be held swingably relative to the arm. In addition, "wound" implies, for example, that the wire is wound tightly around an object such as a shaft or a pin while being in physical contact with the object, or that the wire is wound with some play (or clearance) between the object and the wire.

[0015] In the above-described feature, the repulsive tool may be fixed only to the pressing tool without being held by the arm.

[0016] In the above-described features, the arm may be provided with a male screw or a female screw, the sub-arm may be provided with a female screw or a male screw, and the male screw or the female screw of the arm may be screwed into the female screw or the male screw of the sub-arm, so that the sub-arm can be detachably attached to the arm.

[0017] In the above feature, a groove may be provided in the arm, and the repulsive device may be arranged so that at least a portion of the repulsive device is fitted and held in the groove. In this case, it is possible to adopt a mode in which a dowel-like protrusion or shaft is included in the groove.

[0018] In the above feature, the base portion may be disposed at or near the other end of the arm, and one of the pair of pressing tools may be provided outside the other end of the arm.

[0019] In the above feature, a gripping portion having a shape and / or material different from other portions of the arm may be provided on at least one end side of the arm.

[0020] In the above-mentioned features, a self-supporting foot may be provided for holding the medicine applicator in a self-supporting position.

[0021] In the above feature, the pressing tool may include a restricting portion that restricts the operation of the rebounding tool.

[0022] The "regulating portion for regulating the action of the repulsive tool" includes any part that can regulate the action of the repulsive tool in a predetermined manner. For example, uneven portions (e.g., guide grooves and guide ribs) that can regulate the repulsive tool to slide along a predetermined track, through-holes (e.g., passage holes and slits) that can regulate the repulsive tool to pass within a predetermined range, and pivotal portions that can regulate the repulsive tool to perform a predetermined rotational movement are all included. Furthermore, for example, among the specific aspects of the regulating portion, guide grooves, guide ribs, passage holes, slits, etc. can be rephrased as guide portions that guide the repulsive tool, that is, guide portions that can guide the relative movement of the repulsive tool with respect to the pressing tool in a predetermined manner.

[0023] The present invention also provides a kit for applying a medicine, comprising the medicine applicator described above and an application member to be placed on the base.

[0024] The present invention also provides a pressing tool for a drug applicator, which removably holds an application member on the drug applicator, and which comprises a support part that is swingably supported on the drug applicator, a contact part that extends from the support part and can contact the application member, and a knob part that extends from the support part in a direction different from the contact part and is used for gripping.

[0025] In the above-mentioned features, the pressing tool for a medicine applicator may have a through hole through which at least a part of the medicine applicator can be inserted.

[0026] In the above feature, the contact portion may be provided with a non-slip portion having a projection and / or a recess. Effect of the Invention

[0027] According to the present invention, a pressing tool (clamping means, etc.) such as a clip, which can detachably hold an application member (or treatment product), is provided on an arm having a base portion integrally formed with the arm, so that the application member (or treatment product) can be easily attached and detached with a simple configuration. Also, since the application member (or treatment product) is simply held by a pressing tool (clamping means, etc.) such as a clip, reduction in the effective area of ​​the application member (or treatment product) used to apply chemicals, etc. can be suppressed. Also, a finger rest for assisting in the operation of the pressing tool or for operating the pressing tool is provided, so that operability can be improved. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0029] An embodiment of a drug applicator according to the present invention will be described below with reference to the drawings. Fig. 1(a) is an exploded perspective view of an embodiment of a drug applicator 100 according to the present invention, Fig. 1(b) is a partial top view of the drug applicator 100 shown in Fig. 1(a), and Fig. 1(c) is a partial side view of the drug applicator 100 shown in Fig. 1(a).

[0030] The drug applicator 100 includes an applicator body 200 having a rod-shaped arm 10 extending to a length of about 30 to 70 cm and a base 222 disposed on the arm 10 substantially parallel to the longitudinal direction of the arm 10. For example, when the arm 10 and the base 222 are both made of synthetic resin, the applicator body 200 can be integrally molded by molding, injection molding, or the like. For example, when the arm 10 is made of wood or a lightweight metal such as aluminum, the base 222 may be fixed to the arm 10 made of wood or a lightweight metal with a screw or the like to be integrated. For example, the base 222 may be fixed to the arm 10 made of synthetic resin with a screw or the like to be integrated. The base 222 may be connected to the arm 10 via a connecting material (not shown) such as a spacer to be integrated. Further, in addition to the embodiment in which the arm 10 and the base part 222 are integrated, as shown in the above example, the arm 10 and the base part 222 may be joined with screws or the like to be detachable, allowing the size of the base part 222 to be changed, or allowing easy cleaning of the details. The portion where the arm 10 and the base part 222 are joined or integrated constitutes the concentration part 220 with the column part forming a part of the axial direction of the arm 10 and the base part 222. More specifically, the concentration part 220 is a part of the arm 10 that is constituted by the pressing tool (clip) 130, the mounting shaft (holding shaft) 268 of the pressing tool (clip) 130, the base part 222, the repulsion tool, and the repulsion tool holding part (including holding means such as the mounting shaft 268).

[0031] A gripping part 11 is formed on one end of the arm 10 to be gripped by the recipient himself / herself. The length of the gripping part is about 10 cm to 25 cm. In the drug applicator 100 of this embodiment, a structure is adopted in which the scratching handle of a backscratcher is replaced with the applicator body 200, so that the arm 10 is slightly curved to facilitate application of the drug to the back of the recipient. However, the arm 10 may not only be curved in one direction, but may also be curved in multiple directions (for example, a shape curved in a roughly S-shape, etc.), or may extend, for example, linearly.

[0032] The side of the arm 10 of the applicator body 200 opposite the grip part 11 is an extension part 14 extending outward from the base part 222 to such an extent that it does not affect the operation of the base part 222. The extension part 14 is usually about 1 cm to 5 cm, but when the drug applicator 100 is held with both hands as in the embodiment described later, it is replaced with an auxiliary arm 400 extending about 30 cm to 70 cm, and the second grip part 11 is disposed (formed) at the end of the auxiliary arm 400. The extension part 14 may or may not pass through a through hole 134 of the pressing tool 130 described later.

[0033] Further, in order to reliably hold the applicator member 300 on the base portion 222, the applicator body 200 is provided with a pair of pressing tools 130 having a generally rectangular outer shape (the cross-sectional shape of the pressing tool 130 may be arch-shaped, generally S-shaped, or crank-shaped, which are easy to fit to the shape of fingers) in the axial direction of the concentrating portion 220 and in the vicinity of the front and rear positions of the base portion 222 so as to be able to swing substantially symmetrically. The configuration of the pressing tool 130 is also shown in FIG. 2. FIG. 2 shows a top view (a), a side view (b), and a front view (c) of the pressing tool 130, and FIG. 2(d) is a side view explaining the operation of the pressing tool 130. The pressing tool 130 is formed into a generally rectangular plate shape that is slightly long in one direction (the vertical direction in FIGS. 2(b) to 2(d)). On the front side of the pressing tool 130, near one end in the length direction of the pressing tool 130 (the lower end in Figs. 2(b) to (d)) and approximately in the center in the width direction, there is a through hole 134 that is somewhat long and approximately oval in the length direction of the pressing tool 130, which prevents interference with the extension part 14, the concentrating part 220, and the arm 10 when the pressing tool 130 is attached near the base part 222 of the applicator main body 200. In other words, the pressing tool 130 is configured to have a through hole 134 that allows at least a part of the drug applicator 100 to pass through.

[0034] In order to attach the pressing tool 130 to the concentrating portion 220, a hole 137 is provided which extends in the width direction from near the center of the length of the through hole 134 of the pressing tool 130 to both long side portions of the pressing tool 130. The hole 137 is fitted with an attachment shaft 268 which is inserted into an attachment hole 265 of the concentrating portion 220 described later. When viewed from the side, as shown in FIG. 2(b), when an imaginary line A1 extending from the center of the hole 137 toward the front of the pressing tool 130 so as to intersect perpendicularly with the pressing tool 130 is taken as a cutting line, a knob portion 138 is formed on the anti-base portion 222 side (upper side in the figure) S2 opposite to the base portion 222 side (lower side in the figure) S1, and a contact portion 132 whose tip portion is bent toward the base portion 222 is formed on the base portion 222 side S1. That is, the pressing tool 130 is a pressing tool that detachably holds the applicator member 300 on the drug applicator 100, and is a pressing tool for a drug applicator that is equipped with a hole 137 which is a pivotal support part that is swingably supported on the drug applicator 100, a contact part 132 that extends from the pivotal support part and can abut against the applicator member 300, and a knob part 138 that extends from the pivotal support part in a direction different from the contact part 132 and is used for gripping.

[0035] 1(a) and 2(a), a guide rail 160 is formed on the back surface (side surface of the base portion 222) of the pressing tool 130, from the vicinity of the through hole 134 toward the other end in the length direction of the pressing tool 130 (the upper end in FIG. 1(a)). That is, on the side surface in the bending direction of the abutting portion 132, the pressing tool 130 is provided with a groove-shaped guide rail 160 having a substantially arc-shaped cross section, which extends linearly from approximately the center of the short side forming the other end in the length direction of the pressing tool 130 (the upper end in FIG. 1(a)) along the length direction of the pressing tool 130 (the up-down direction in FIG. 1(a)) to a position near one end in the length direction of the through hole 134 (the upper end in FIG. 1(a)). The guide rail 160 is formed to have a width and depth that allow the bent portion 2921 of the rebounding tool (kick spring) 292 described later to be fitted with some margin (play). At least the surface (inner surface) of the guide rail 160 desirably has, for example, excellent sliding characteristics (low friction coefficient, high wear resistance, etc.). For this reason, for example, at least the surface (inner surface) of the guide rail 160 may be made of a material with excellent sliding characteristics such as resins such as polyacetal, polyamide, polytetrafluoroethylene (PTFE), etc., or, depending on the material of the pressing tool 130, a surface layer made of a material with excellent sliding characteristics as described above may be provided on the surface (inner surface) of the guide rail 160. Also, although the embodiment requires a guide rail, the embodiment also corresponds to an embodiment in which the guide rail is not used.

[0036] A pair of mounting holes 265 (one pair per one of the left and right sides) are arranged on the side of the concentrated portion 220 of the applicator body 200 and are arranged almost symmetrically in the axial direction on both the left and right sides, and a mounting shaft 268 is inserted and attached to the mounting holes 265. The mounting shaft 268 fits into a hole 137, and the pressing tool 130 is attached to the concentrated portion 220 so as to be able to swing. As shown in FIG. 1(c), the end (both ends) of the repulsive tool (kick spring) 292 is bent inward (toward the coil) in a hook shape, thereby forming a bent portion 2921 that is locally bent in a curved shape, and this bent portion 2921 presses the back side of the knob portion 138 of the pressing tool 130, or the end treatment of the repulsive tool may be such that the end of the repulsive tool does not provide resistance between the pressing tool and the pressing tool when the pressing tool is operated, for example, it may extend in a straight or arc shape, or the tip may be processed into a substantially spherical shape, etc. At this time, the bent portion 2921 of the repulsive tool (kick spring) 292 is fitted into the guide rail 160, and while sliding (sliding) inside the guide rail 160, it presses the back side of the knob portion 138 of the pressing tool 130. Here, for example, if the pressing tool is not provided with a portion such as a guide rail, the repulsive tool may deviate (deviate) from the intended direction relative to the pressing tool, and as a result, the pressing force of the repulsive tool may not be sufficiently transmitted to the pressing tool. In contrast, according to the configuration in which the operation of the repulsive tool (kick spring) 292 is restricted by the guide rail 160 (restriction portion) as in this embodiment, the operation of the repulsive tool can be performed more reliably and easily, and the pressing force of the repulsive tool can be reliably and sufficiently transmitted to the pressing tool. In particular, as in the above example, the bent portion 2921 is locally bent in a curved shape, and by sliding (sliding) inside the guide rail 160 on the outside thereof, it is possible to slide (slide) more smoothly. The mounting shaft 268 is fixed in the mounting hole 265, but the mounting shaft 268 may be rotatably fitted into the mounting hole 265 and fixed in the hole 137 of the pressing tool 130 by welding, crimping, brazing, adhesive, etc.

[0037] Grooves 232 having various shapes, such as a roughly crescent shape in side view, a square shape, a rectangular shape, an ellipse shape in top view, or a cylindrical shape in oblique view, are arranged in the axial direction (length direction of arm 10) of the upper peripheral surface of concentrating portion 220, and holes 235 are provided through which grooves 232 pass in the radial direction of concentrating portion 220, and pressing pins 234 are installed in grooves 232 using holes 235. Pressing pins 234 may be inserted into holes 235 and fixed by friction, or after fitting, the ends may be treated to prevent them from falling out, such as by caulking. Pressing pins 234 may be long headed screws, and one side of through hole 235 may be combined as a nut. By winding the coil portion of the repulsive element (kick spring) 292 around the pressing pin 234 (see FIGS. 1(b) and (c)), in other words, by arranging the repulsive element (kick spring) 292 so that at least a portion of it is fitted and held within the groove 232, it is possible to securely hold the repulsive element (kick spring) 292, which is arranged in a pre-biased state and presses against the back side of the knob portion 138 of the pressing tool 130, in the concentrating portion 220.

[0038] With reference to Fig. 1(c), the action of the repulsive tool (kick spring) 292 in a state where it is pre-biased and attached, and the operation of the pressing tool due to the action will be described in detail. Fig. 1(c) shows a state where the repulsive tool (kick spring) 292, which is a spring as a repulsive tool for the pressing tool, and one (the right in the figure) pressing tool 130 are attached, and the other (the left in the figure) pressing tool 130 is removed. The coil-shaped part of the repulsive tool (kick spring) 292 is wound around the pressing pin 234 and held by the concentrating part 220, so that its movement is restricted. The bent part 2921 of the repulsive tool (kick spring) 292 is slidably fitted into the guide rail 160 of the pressing tool 130 without being fixed, and presses the back side of the knob part 138 of the pressing tool 130 held by the concentrating part 220 to be swingable, by the elastic force (restoring force) of the repulsive tool (kick spring) 292. The pressing tool 130 pressed by the elastic force rotates around the mounting shaft 268 (hole 137) as a central axis by the principle of a lever, as shown in Fig. 2(d), and the rotational motion stops when the abutting part 132 on the side opposite the knob part 138 is pressed against the base part 222 via (or without) the application member 300. The elastic force (restoring force) of the repulsive tool (kick spring) 292, which is attached with a bias in advance, continues to act and is maintained without being released unless any of the above-mentioned components are deformed or damaged under the above-mentioned conditions. The elastic force (restoring force) of the repulsive tool (kick spring) 292 acts as a force (rotational moment) that presses the back side of the knob part 138 of the pressing tool 130 and rotates the pressing tool 130.

[0039] The knobs 138, 138 of the pressing tool 130, which are provided almost symmetrically with their back faces facing each other, rotate and move away from each other due to the pressure of the elastic force (restoring force) of the repulsive tool (kick spring) 292. As a result, the abutting parts 132, which are parts below the center of oscillation (hole 137) of the rotating pressing tool 130, approach each other and abut against the base part 222 via (or without) the application member 300. The application member 300, which is placed against the side and bottom surfaces of the base part 222, is pressed against the base part 222 by the abutting parts 132 and clamped. This state is the state in which the application member 300 is held by the application tool main body 200. To attach or detach the application member 300 from the application tool main body 200, a force against the elastic force (restoring force) of the repulsive tool (kick spring) 292 is applied to the repulsive tool (kick spring) 292 via the knobs 138. That is, the pair of pressing tools 130 are pressed with fingers so that knobs 138 approach each other, and pressing tools 130 are swung. By pressing knobs 138 with fingers with a force stronger than the elastic force (restoring force) of repulsion tool (kick spring) 292, each knob 138 rotates around attachment shaft 268 (hole 137) and approaches each other. As a result, abutment parts 132, 132, which are parts below the swing central axis (hole 137) of rotating pressing tool 130, are separated from base part 222, and a space for attaching and detaching applicator 300 is created. This state is the state in which applicator 300 is released from applicator body 200.

[0040] The application member 300 is disposed on the bottom side of the base portion 222. More specifically, as shown in FIG. 2(d), the application member 300 is disposed so as to cover the bottom portion of the base portion 222 and further wrap around the side portion, and is held by being pressed against both side portions of the base portion 222 from both sides by the abutting portions 132 of a pair of pressing tools 130 and being sandwiched. However, the application member 300 can be disposed in other manners than the above. For example, the application member 300 may be disposed so as to cover only a part of the bottom portion of the base portion 222, rather than the entire bottom portion. In other words, the application member 300 can be disposed so as to cover the entire or a part (at least a part) of the bottom portion of the base portion 222. For example, the application member may be disposed so as to cover only the bottom portion (at least a part) without extending to the side portions of the base portion, and the peripheral portion of the application member may be pressed against the bottom portion of the base portion by the abutting portions of the pressing tools to hold the application member (not shown). In this embodiment, for example, if the tip of the pressing tool is formed in a shape that is further bent inward (towards the knob portion), a configuration can be made in which the tip can press the bottom surface of the pedestal portion.

[0041] Any of cotton puffs, cut cotton, paper, cloth, etc. soaked in medicine, or paste-like medicine can be used as the application member 300. The sizes of commercially available cotton puffs are 60×80, 58×70, 50×60, 55×70, 50×65 (these dimensions are in mm), i.e., short sides are about 50 to 60 mm and long sides are about 60 to 80 mm, and the sizes of cut cotton are 40×40, 50×60, 50×50, 50×70, 56×80, 70×70 (these dimensions are in mm), i.e., short sides are about 40 to 70 mm and long sides are about 40 to 80 mm. Therefore, the size of the base 222, i.e., the dimensions of the sides of the bottom surface, may be approximately equal to or smaller than the dimensions of the sides of the application member 300. Specifically, the length of the short side (axial direction of arm 10) is about 30 to 60 mm, and the long side (radial direction of arm 10) is about 30 to 80 mm. However, commercially available application members are generally stretchable, and therefore the dimensions of the sides of the bottom surface of base portion 222 may be even greater than the above values. The medicinal applicator 100 and the applicator member 300 placed on the base 222 can form a kit for applying medicinal substances.

[0042] Next, Fig. 3 and Fig. 4 show modified examples of the repulsion tool used in the pressing tool 130 according to the present invention. Fig. 3 shows a modified example in which the repulsion tool is changed from a kick spring to repulsion tools (leaf springs) 294, 296. Fig. 3(a) shows an example in which the repulsion tool (leaf spring) 294 arranged in an upwardly convex shape is used, and Fig. 35(b) shows an example in which the repulsion tool (leaf spring) 296 arranged in a downwardly convex shape is used as the repulsion tool. In the modified example shown in Fig. 3(b), a relief hole 161 is formed in the part directly below the repulsion tool (leaf spring) 296 in the concentrated part 220 of the arm 10 so that this part does not interfere with the repulsion tool (leaf spring) 296. In this modified example, the repulsion tool is fixed only to the pressing tool 130 without being held in the concentrated part 220. Specifically, the repulsion tool can be configured by simply fixing both ends of the repulsion tools (leaf springs) 294, 296 to the back sides of the knobs 138 of the pair of pressing tools 130 in a state where the repulsion tools are not held in the concentrating portion 220, but are biased in advance to the back sides of the knobs 138 of the pair of pressing tools 130. That is, both ends of the repulsion tools (leaf springs) 294, 296 are fixed to the back sides of the knobs 138, 138 of the pressing tools 130 that are arranged almost symmetrically with their back sides facing each other. The knobs 138, 138 are rotated by the repulsion tools (leaf springs) 294, 296 due to the elastic force (restoring force) of the repulsion tools, and the knobs 138 of the pressing tools 130 are moved away from each other.

[0043] In the modified example shown in FIG. 3(b), the escape hole 161 is formed as described above, but, for example, a repulsive tool (leaf spring) may be provided that is arranged in a downward convex shape so as to avoid the concentrated portion of the arm (in the positional relationship shown in FIG. 3(b), the repulsive tool (leaf spring) may be arranged at both ends in the width direction of the pressing tool 130, i.e., at the front and rear ends of the pressing tool 130 in the figure, so as to be offset laterally from the concentrated portion 220). With this configuration, the escape hole may be unnecessary.

[0044] As a specific example of attaching the repulsion tools (leaf springs) 294, 296 to the knob portion 138, if the knob portion 138 and the repulsion tools (leaf springs) 294, 296 are made of materials that melt into each other, they can be attached by welding or bonding. If the knob portion 138 and the repulsion tools (leaf springs) 294, 296 are made of materials that do not melt into each other, they can be attached by fastening, riveting, screwing, brazing, or the like. Alternatively, if a holder into which the ends of the repulsion tools (leaf springs) 294, 296 can be fitted is disposed on the rear side of the knob portion 138 and the ends of the repulsion tools (leaf springs) 294, 296 are inserted, the ends of the repulsion tools (leaf springs) 294, 296 can be reliably fixed to the knob portion 138. The repulsive tools (plate springs) 294, 296 may be securely fixed to the holder by riveting or soldering to the fitting portion. The action of the elastic force (restoring force) of the repulsive tool on the pressing tool and the action of the pressing tool due to the action are the same as those shown in Figs. 1 and 2 above.

[0045] The two ends of the repulsion tools (leaf springs) 294, 296 may be fixed to the pressing tool 130 as described above. Alternatively, for example, the two ends of the repulsion tools may be rotatably attached to the pressing tool by being supported on an axis extending along the width direction of the leaf spring (or the width direction of the pressing tool), thereby making the operation of the pressing tool smoother.

[0046] 4 shows an example in which the mounting position and shape of the repulsive tool (kick spring) 292 are changed, and further, an example in which the repulsive tool is changed to a leaf spring, in which (a) is a top view of the applicator body 200 including the repulsive tool (kick spring) 292, (b) is a front view of the applicator body 200, (c) is a side view of the applicator body 200, (d) is a front view of the applicator body 200 including the repulsive tool (leaf spring) 292a, and (e) is a side view thereof. In order to clearly show the repulsive tool (kick spring) 292 and the repulsive tool (leaf spring) 292a, the pressing tool 130 is omitted in these figures (except for one shown by a dashed line in Figs. 4(c) and (e)).

[0047] Specifically, two piece-like holding parts 284, 284 are integrally formed on the upper peripheral surface of the concentrated part 220 of the applicator body 200 so as to be erected in a posture parallel to the longitudinal direction of the arm 10 while facing each other with a gap therebetween. Each holding part 284 is formed with a hole, into which the shaft 290 is inserted and fixed. The coil part of the repulsive tool (kick spring) 292 is wound around the shaft 290, and the shaft 290 is arranged in a pre-biased state. Bent parts 2921 are formed on both ends of the repulsive tool (kick spring) 292, and the bent parts 2921 are fitted into the guide rail 160 (not shown in FIG. 4) of the pressing tool 130 shown by the dashed line and slide, pressing the back side of the knob part 138 of the pressing tool 130. 1, the pressing tool 130 is held swingably by an attachment shaft 268 inserted into attachment holes 265 arranged on the left and right side surfaces of the concentrating portion 220. In this modification, like the embodiment shown in FIG. 1, the pressing tool 130 reliably holds the application member 300 attached to the base portion 222 in a detachable manner. The action between the repulsive tool (kick spring) 292 that presses the back side of the knob 138 of the pressing tool 130 and the pressing tool (such as a clip) and the operation of the pressing tool due to this action are similar to the above embodiments and modifications.

[0048] 4(d) and (e), a holding part 284 of the repulsive tool is formed as in FIG. 4(a) to (c), but since the repulsive tool is a leaf spring, the repulsive tool (leaf spring) 292a, which is the repulsive tool, does not wind the coil part of the repulsive tool (kick spring) around the shaft 290, but simply passes between the upper peripheral surface of the concentrated part 220 of the applicator body 200 and the shaft 290. The repulsive tool (leaf spring) 292a passes between the upper peripheral surface of the concentrated part 220 of the applicator body 200 and the shaft 290, extends in the axial direction of the concentrated part 220, and is arranged in a pre-biased state, pressing the back side of the knob part 138 of the pressing tool 130. A groove-shaped guide rail having a width and depth corresponding to the width and thickness of the repulsive tool (leaf spring) 292a is formed on the back side of the knob portion 138 of the pressing tool 130 so as to extend vertically (not shown), and the bent portion 2921a of the repulsive tool (leaf spring) 292a is fitted into this guide rail so as to slide. The repulsive tool (leaf spring) 292a may be processed into a bent shape near the shaft 290 to prevent it from coming off the applicator main body 200 due to frictional movement. The action between the repulsive tool, which is the repulsive tool (leaf spring) 292a that presses the back side of the knob portion 138 of the pressing tool 130, and the pressing tool and the operation of the pressing tool due to the action are similar to those of the above-mentioned embodiments and modified examples.

[0049] 5 is a modified example in which the retaining portion 284 is omitted from the modified examples of FIG. 4(d) and (e). A fastening hole is formed at approximately the center of the repulsive tool (leaf spring) 292b. A fastening hole or fastening shaft is arranged on the upper peripheral surface of the concentrating portion 220, and the fastener 293 fixes the repulsive tool (leaf spring) 292b to the concentrating portion 220 using the hole provided in the repulsive tool (leaf spring) 292b. The repulsive tool (leaf spring) 292b is formed to a length that presses the rear side of the knob portion 138 of the pair of pressing tools 130, extends from the fastening hole portion in the axial direction of the concentrating portion 220, and is arranged in a pre-biased state, and the bent portion 2921a is fitted into the guide rail (not shown) and slid while pressing the rear side of the knob portion 138 of the pressing tool 130. The action between the pressing tool, which is the repulsive tool (leaf spring) 292b that presses the back side of the knob portion 138 of the pressing tool 130, and the pressing tool and the operation of the pressing tool due to this action are similar to those of the above-described embodiments and modified examples.

[0050] Another modified example in which a repulsive tool is held in concentrated portion 220 of applicator body 200 is shown in Fig. 6. Fig. 6(a) is a top view when a repulsive tool (leaf spring) 292a is used as the repulsive tool, and Fig. 6(b) is a side view thereof.

[0051] The groove 232 is formed in the same manner as in the embodiment shown in Fig. 1. That is, the groove 232 having a roughly crescent shape is arranged in the axial direction (length direction of the arm 10) of the upper peripheral surface of the concentrating portion 220, and a hole 235 is provided at the approximate center position of the groove to pass the concentrating portion 220 through the groove 232 in the radial direction, and the hole 235 is used to install the pressing pin 234 in the groove 232. By passing the repulsive tool (leaf spring) 292a between the pressing pin 234 and the bottom surface of the groove 232, in other words, by arranging the repulsive tool (leaf spring) 292a so that at least a part of the repulsive tool (leaf spring) 292a is fitted and held in the groove 232, the repulsive tool (leaf spring) 292a, which is arranged in a pre-biased state and presses the back side of the knob portion 138 of the pressing tool 130, can be reliably held in the concentrating portion 220. The action between the pressing tool and the repulsive member (leaf spring) 292a that presses the back side of the knob portion 138 of the pressing tool 130, and the operation of the pressing tool due to the action are the same as those in the above-mentioned embodiments and modified examples. The end portions of the leaf springs in the above-mentioned embodiments of Figures 4(d) and (e), Figure 5, and Figures 6(a) and (b) may be fixed or held on the back side of the knob portion 138 of the pressing tool 130 as in the modified examples of Figures 3(a) and (b).

[0052] (Other variations) (1) Next, a modified example of the drug applicator 100 according to the present invention is shown in FIG. 7. This modified example changes the configuration of the arm 10, and can be applied to any of the applicator bodies 200 shown in the above-mentioned embodiments and modifications. FIG. 7 is a side cross-sectional view of the drug applicator. In the above-mentioned embodiments and modifications, a relatively short extension 14 is provided at the end of the applicator body 200 opposite the gripping portion, but an auxiliary arm 400 having a gripping portion (not shown) is added in the axial direction of the arm 10. That is, by forming the drug applicator 102 with the auxiliary arm 400 and the arm 10, the user can grip the gripping portions 11 provided at both ends of the auxiliary arm 400 and the arm 10 and move the applicator body 200 on the skin in the manner of dry cloth friction. This increases the operability of the applicator body 200. Therefore, the base 222 is arranged at or near the other end (opposite gripping end) of the arm 10, and a male screw 412 is formed at the opposite gripping end of the arm 10, and a female screw 414 is formed at the end of the auxiliary arm 400. By screwing the male screw 412 and the female screw 414 together, the auxiliary arm 400 can be detachably attached to the arm 10 to form a double-grip type drug applicator 102. According to this modification, the drug applicator 102 can be used by being grasped with both hands. Of course, in the drug applicator 102 according to this modification, the auxiliary arm 400 and the arm 10 can be disassembled, and the arm 10 without the auxiliary arm 400 can be used in the same manner as in the embodiment shown in FIG. 1. The male screw 412 and the female screw 414 may be arranged in the opposite manner to the above (i.e., the female screw is arranged at the opposite gripping end of the arm 10, and the female screw is arranged at the end of the auxiliary arm 400).

[0053] (2) The joining structure between the arm and the auxiliary arm is not limited to the above-mentioned structure of screwing a male screw (or female screw) on the arm and a female screw (or male screw) on the auxiliary arm. For example, as shown in Fig. 8, a mortise portion 514 and a screw hole 514a that penetrates the side wall of the mortise portion 514 in the radial direction may be formed at the end of the auxiliary arm 500, and a tenon portion corresponding to the mortise portion 514 may be formed at the end of the arm opposite to the gripping portion (not shown), and the tenon portion may be inserted into the mortise portion 514 and a screw 514b may be screwed into the screw hole 514a from the outside to join the auxiliary arm 500 to the arm.

[0054] (3) 9 to 11, a tenon portion and a secondary tenon portion may be formed in addition to the tenon portion and the mortise portion. In the joint structure shown in the figures, a tenon portion 612 is formed at the end of arm 610 opposite the gripping portion, and a mortise portion 614 is formed at the end of auxiliary arm 600.

[0055] 10, tenon portion 612 extends in the axial direction from the end of arm 610 opposite the gripping portion in a cylindrical shape with a diameter slightly smaller than the diameter of arm 610. A sub-mortise portion 612a is formed within tenon portion 612, the sub-mortise portion 612a having an inner diameter even smaller than the diameter of tenon portion 612 and extending in a circular hole shape over almost the entire length in the axial direction. Also, at approximately the center of tenon portion 612 in the axial direction, a groove portion 612b is formed extending in the circumferential direction, recessing from the surface with an arc-shaped cross section.

[0056] As shown in Fig. 11, the mortise portion 614 is formed at the end of the auxiliary arm 600 so as to recess in the shape of a circular hole with an inner diameter and depth corresponding to the tenon portion 612, and similar to the modified example shown in Fig. 8 described above, a screw hole (not shown) is formed which penetrates the side wall portion of the mortise portion 614 in the radial direction. Also, at the center of the innermost surface of the mortise portion 614, a secondary tenon portion 614a is formed which has a diameter and length corresponding to the secondary tenon portion 612a and extends cylindrically in the axial direction.

[0057] Auxiliary arm 600 can be joined to arm 610 by inserting tenon portion 612 into mortise portion 614 and screwing screw 614b into the screw hole from the outside as shown in Figure 9. According to this joining structure, secondary mortise portion 612a and secondary tenon portion 614a enable a more reliable and stable joining.

[0058] (4) Furthermore, for example, as shown in Fig. 12, the base part 722 may be disposed at the approximate center of the arm 710, and both ends of the arm 710 may be used for gripping. The drug applicator 700 shown in the figure has a long, rod-like arm 710, a base part 722 disposed on the arm 710, and pressing tools 713, 713, similar to the drug applicator 100 according to the embodiment shown in Fig. 1, but whereas the arm 10 according to the embodiment shown in Fig. 1 has a length of about 30 to 70 cm, the arm 710 according to this modification has a total length of about 60 to 140 cm, which is longer by about the length of the auxiliary arm, about 30 to 70 cm. In other words, the arm 710 of this modified example has a total length of approximately 60 to 140 cm, which roughly corresponds to the sum of the length of approximately 30 to 70 cm of the arm 10 of the embodiment shown in Figure 1 plus the length of approximately 30 to 70 cm of the auxiliary arm 400 of the modified example shown in Figure 7, and is an undivided structure, i.e., the arm and auxiliary arm are not divided, but are formed integrally from the beginning.

[0059] A base portion 722 is disposed in the approximate center of arm 710 according to this modification, and both ends of arm 710 are configured to be used for gripping as gripping portions 711, 711, respectively.

[0060] With drug applicator 700 of this modification, a user can grip grips 711, 711 formed at both ends and move the applicator body over the skin in a manner similar to dry cloth friction. This increases the operability of the applicator body, as with drug applicator 102 of the modification shown in Figure 7.

[0061] (5) Next, a further modified example of the drug applicator 100 according to the present invention is shown in Fig. 13. As in the above-mentioned embodiments and modifications, the drug applicator 800 according to this modification includes an arm 810, a base portion 822, and pressing tools 813a and 813b. However, unlike the above-mentioned embodiments and modifications, the base portion 822 is disposed at or near the other end of the arm 810, and one pressing tool 813b of the pair of pressing tools 813a and 813b is disposed outside the other end of the arm 810. Moreover, the arm 810 is not a round bar-like arm but is an approximately rectangular column-like arm with chamfered corners.

[0062] In drug applicator 800 of this modified example, pedestal 822 is arranged so that one long side (one long side along the width direction of arm 810) is located slightly inside the other end of arm 810, in other words, pedestal 822 is located at a position not too far inside the other end of arm 810 (or at a position nearly aligned with the other end of arm 810), and its upper surface overlaps the other end of arm 810. A pair of mounting holes 865 similar to mounting holes 265 in the embodiment shown in Fig. 1 are arranged on both left and right side surfaces on the side surface of arm 810 near pedestal 822 and at positions nearly symmetrical in the axial direction, and a pair of pressing tools 813a, 813b are provided to be swingable in the same structure as in the embodiment shown in Fig. 1.

[0063] According to the medicine applicator 800 of this modification, since it is not necessary to consider interference with the arm 810 when the pressing tool 813b is attached to the outside of the other end of the arm 810, no through hole is provided as shown in Fig. 13(a). Therefore, there is an advantage that the appearance of the pressing tool 813b provided on the outside can be improved accordingly. In this case, for example, if the base part 822 substantially protrudes outward from the other end of the arm 810, it is undesirable because it will interfere with the pressing tool 813b provided on the outside. However, the base part 822 may protrude outward from the other end of the arm 810 within a range where it is unlikely to interfere with the outer pressing tool 813b.

[0064] However, instead of one pressing tool 813b provided outside the other end of the arm 810, a pressing tool having a through hole similar to pressing tool 130 according to the embodiment shown in Fig. 1 may be arranged. That is, one pressing tool 813b provided outside the other end of the arm 810 may also have a through hole similar to (or symmetrical with) the other pressing tool 813a. In this case, it is also possible to configure the device such that an auxiliary arm can be added, similar to the case of drug applicator 102 according to the modified example shown in Fig. 7. The configurations of the pressing mechanisms (repulsion members, etc.) in the modified examples of FIGS.

[0065] (6) Further modified examples of the drug applicator 100 according to the present invention are shown in Figures 14 and 15. Drug applicators 900A and 900B according to these modifications have a gripping portion provided on at least one end of the arm, the gripping portion having a shape different from that of the other portion of the arm.

[0066] The gripping part may be a gripping part having substantially the same configuration as the other parts of the arm, as with gripping part 11 of drug applicator 100 of the embodiment shown in Figure 1, for example. However, by using a gripping part having a different configuration from the other parts of the arm, as with drug applicators 900A and 900B of this modified example, it is possible to further improve ease of gripping, ease of handling, etc.

[0067] In a modified drug applicator 900A shown in Fig. 14, one end of a round bar-shaped arm 910A with a circular cross section is shaped into a generally horizontally elongated diamond-shaped cross section to form a gripping part 911A. Both side edges of gripping part 911A are chamfered to form an arc-shaped cross section.

[0068] In a drug applicator 900B according to a modified example shown in Figure 15, one end of an arm 910B in the shape of a round bar with a circular cross section is formed into a flat plate shape by compressing both sides (both the top and bottom in Figure 15) radially toward the center to form a gripping part 911B. Both end edges are formed into an arc-shaped (approximately semicircular) cross section.

[0069] With gripping portions 911A, 911B as described above, when gripped in the hand, the gripping position is less likely to shift circumferentially, allowing for a more secure grip; furthermore, even when operating on the back where the recipient cannot see, the position (angular position) of medicinal applicators 900A, 900B around the axis can be easily and reliably grasped, and medicinal applicators 900A, 900B can be easily controlled and maintained at the desired angular position.

[0070] Furthermore, in addition to the grips 911A and 911B described above, for example, a grip may be formed by forming a layer of rubber or the like on the surface of at least one end of the arm, or by forming the surface into an uneven shape to provide an anti-slip portion. In other words, the grip may have a different shape and / or material from other parts of the arm. In addition, the various grips exemplified above may also be provided on the other end of the arm or the auxiliary arm.

[0071] (7) The contact portion of the pressing tool can have various configurations, for example, as shown in Figures 16(a) to 16(f), it can have a non-slip portion consisting of a convex portion and / or a concave portion.

[0072] The contact parts 132a to 132c shown in Figures 16(a) to 16(c) are all formed by bending the tip part toward the base part, similar to the contact part 132 according to the embodiment shown in Figure 1, and the contact parts 132d to 132f shown in Figures 16(d) to 16(f) are all formed directly on the side surface of the base part without bending the tip part. This provides various types of anti-slip features at the parts that may come into contact with the applicator member.

[0073] The contact parts 132a to 132c shown in Fig. 16(a) to Fig. 16(c) are formed so that the tip of the pressing tool is bent inward (towards the base part), thereby forming ridges 135a to 135c as convex parts. More specifically, the ridge 135a shown in Fig. 16(a) has a straight tip edge, the ridge 135b shown in Fig. 16(b) has a wavy tip edge, and the ridge 135c shown in Fig. 16(c) has a valley-mountain tip edge.

[0074] The contact parts 132d to 132f shown in Fig. 16(d) to Fig. 16(f) are configured with convex and / or concave parts formed on the side surface of the base part of the tip part. More specifically, the contact part 132d shown in Fig. 16(d) is formed into an uneven surface part 135d consisting of a large number of concaves and convexes by embossing. The contact part 132e shown in Fig. 16(e) is formed into an uneven surface part 135e by providing a plurality of slits along the width direction of the pressing tool. It is to be noted that instead of or in addition to the slits, protrusions protruding from the side surface of the base part of the tip part may be provided. The contact part 132f shown in Fig. 16(f) is formed into an uneven surface part 135f having a lattice-like uneven shape.

[0075] Furthermore, in addition to the above, for example, a sand-like surface treatment is applied to the side of the base portion of the tip part (by coating or etching, etc.), or alternatively, no treatment is applied to the side of the base portion of the tip part.

[0076] (8) As the arm, in addition to a round bar-shaped one such as the arm 10 in the above embodiment, or a prismatic one such as the arm 810 in the above modification (5), various shapes such as an approximately T-shaped cross section or an approximately H-shaped cross section can be used. In addition, the arm may be solid or hollow (tubular). Furthermore, the arm may be extendable by using a nesting structure or the like.

[0077] According to the above-described embodiment and each modified example of the present invention, it is possible to evenly apply anti-inflammatory agents, medicines, cosmetics such as sunscreen, etc. to the back of the person to whom the application is to be applied, which cannot be seen by the person himself / herself.

[0078] (9) In the above embodiment and each modified example, the main body of the concentrating portion 220 and the arm 10 on the grip side are integrally arranged as described above, but as shown in FIG. 17, for example, the main body of the concentrating portion 220 and the arms 10 on the grip side 11 and the extension side 14 are separated along a cut surface parallel to the radial direction as shown by the dashed line A2, and both are rotatably connected in the axial direction by the connecting shaft 295. The arm 10 on the extension side 14 may be left integral with the main body of the concentrating portion 220 without being separated. That is, at least the main body of the concentrating portion 220 and the arm 10 on the grip side 11 may be configured to be separated. By configuring the concentrating portion 220 and the arm 10 on the grip side to be rotatable (or swingable) in this way, it is possible to rotate the base portion 222 two-dimensionally (in a swiveling manner) in the left-right direction relative to the grip 11 as shown by the arrow A3, and to smoothly bring the applicator 300 into close contact with the curved surface of the skin of the person to be applied.

[0079] (10) Next, a further modified example of the drug applicator according to the present invention is shown in Fig. 18. The drug applicator S100 shown in this figure is provided with a through-hole as a restricting part that can restrict the passage of the repulsive tool within a predetermined range.

[0080] In this modified example, as shown in Fig. 18(a) and (b), the repulsion tool 162 is formed by molding a leaf spring (or a wire spring, etc.) so as to be curved in a partially missing circular shape (approximately C-shaped). The arm S10 has the same configuration as the arm 10 according to the embodiment shown in Fig. 1, and is configured with escape holes 165, 165 provided on the outer side (opposite the base part 222 side) of the mounting positions of the pair of pressing tools S130, S130, respectively. On the other hand, as shown in Fig. 18(c) and (d), the pressing tool S130 has the same configuration as the pressing tool 130 according to the embodiment shown in Fig. 1, but is not provided with a guide rail. Instead, a through hole 163 and a holding hole 164 are provided in the approximate center in the width direction near the upper end edge and the lower end edge, respectively. The through hole 163 has a cross-sectional shape of a generally horizontally elongated rectangle larger than the cross-section of the repulsion tool 162, and as shown in Fig. 18(c), penetrates the pressing tool S130 from the back surface (the side surface of the base part 222) to the front surface while inclining downward so as to form a curved shape corresponding to the shape of the repulsion tool 162. The holding hole 164 has a cross-sectional shape similar to that of the through hole 163, and as shown in Fig. 18(c), is recessed from the front surface of the pressing tool S130 to the vicinity of the center in the thickness direction while inclining downward so as to form a curved shape corresponding to the shape of the repulsion tool 162 (i.e., it is formed so as to open only on the front side of the pressing tool S130, not penetrate the back side, and terminate inside the pressing tool S130). As shown in Figures 18(a) and (b), the escape hole 165 has a cross-sectional shape that is roughly a horizontally elongated rectangle that is larger than the cross-section of the repulsion tool 162, and penetrates the arm S10 from a position on the side of the periphery of the arm S10 where the base portion 222 is formed (the lower side in Figure 18) that is slightly close to both outer sides of the base portion 222 in the longitudinal direction of the arm S10 to the opposite side (the upper side in Figure 18) while expanding on both outer sides in the longitudinal direction in a curved shape that corresponds to the shape of the repulsion tool 162.

[0081] 18(a) and (b), in the same manner as in the embodiment shown in FIG. 1, a pair of pressing tools S130, S130 are attached to the arm S10, and the repulsion tool 162 is disposed so that it passes through the through holes 163, 163 of both pressing tools S130, S130 and the escape holes 165, 165 of the arm S10 and both ends are fitted into the holding holes 164, 164 of both pressing tools S130, S130. In the disposed state, as shown by the arrow A4 in FIG. 18(b), an elastic force acts toward both ends along the circumferential direction of the repulsion tool 162, whereby both pressing tools S130, S130 can press the application member 300 against the base portion 222 at the abutting portion and hold it. On the other hand, if a pair of pressing tools S130, S130 are clamped close to each other with their gripping portions against the elastic force of the repulsion tool 162, the abutment portions of both pressing tools S130, S130 can be moved away from the application member 300 to release the application member 300; however, since this release action causes the repulsion tool 16 to move in an outward direction, the through hole 163, the retaining hole 164 and the escape hole 165 are formed with a sufficient margin so as not to interfere with the movement of the repulsion tool 16.

[0082] According to this modification, the operation of the repulsion tool 162 is restricted by the through hole 163, the holding hole 164, and the escape hole 165, so that the operation of the repulsion tool 162 is more reliably and easily performed, as in the case of the embodiment shown in Fig. 1, and thus the pressing force of the repulsion tool 162 is reliably and sufficiently transmitted to the pressing tools S130, S130, and even if a force is applied to the repulsion tool in the radial direction or sometimes in the axial direction, the repulsion tool will not be removed from the applicator body and the function of the drug applicator will not be impaired. Note that the through hole 163, the holding hole 164, and the escape hole 165 according to this modification can function as both a restricting part and a guiding part, like the guide rail 160 according to the embodiment shown in Fig. 1.

[0083] (11) Further, a modified example as shown in Fig. 19 may be used. The drug applicator T100 shown in the figure has the same configuration as the drug applicator S100 according to the modified example (10), but is provided with a plurality of repulsive members 162 each composed of a leaf spring (or a wire spring, etc.). The pressing tool T130 according to this modified example has the same configuration as the pressing tool S130 according to the modified example (10), but has through holes 166, 166 and holding holes 167, 167 provided near both ends in the width direction of the upper end edge vicinity and the lower end edge vicinity, respectively, slightly away from the through hole T134 on both sides in the width direction. The two repulsive members 162, 162 are arranged using the through holes 166, 166 and the holding holes 167, 167, respectively, in the same manner as the repulsive tool 162 according to the modified example (10).

[0084] According to this modification, since a plurality of repulsive members 162 are provided, the elastic force of the repulsive members 162 can be applied more effectively and the operation can be made more stable. Furthermore, since the repulsive members 162, 162 are arranged to avoid the position of the through hole T134, they do not interfere with the arm 10, and therefore it is not necessary to provide an escape hole in the arm 10.

[0085] In addition, multiple repulsion devices may be provided, including one that passes through the escape holes 165, 165 of the arm S10, such as the repulsion device 162 in the modified example (10), and three or more repulsion devices may be provided regardless of the arrangement.

[0086] (12) A further modified example of the medicine applicator according to the present invention is shown in Fig. 20. The medicine applicator U100 shown in this figure has a repulsive member 168 provided on the periphery of the arm U10 on the side of the base part 222.

[0087] In this modification, on the periphery of the arm U10 on the side of the base part 222 (the lower side in Figs. 20(a) and (b)), recessed grooves 169, 169 are provided at positions adjacent to the outer side of the base part 222 in the longitudinal direction, so as to recess so as to have a generally triangular tapered shape in cross section, and repulsion tool holding shafts 170, 170 are respectively installed at the innermost parts of the recessed grooves 169, 169 along the width direction of the pressing tool U130. The repulsion tool 168 is composed of a kick spring, and a bent part 1681 is formed at one end, and a coil part is wound around the repulsion tool holding shaft 170. The pressing tool U130 has a structure similar to that of the pressing tool 130 according to the embodiment shown in Fig. 1, and has a guide rail 171 formed on the front surface (the surface opposite to the side surface of the base portion 222) that extends linearly from a position slightly to one side in the width direction from the center of the edge portion (the lower edge portion in Figs. 20(a) and (b)) of the contact portion U132 side of the through hole U134 toward the lower edge of the pressing tool U130. That is, the pressing tool U130 has a guide rail 171 formed on the surface opposite to the bending direction side of the contact portion U132, that extends linearly from a position slightly to one side from the center of the short side that forms the end of the contact portion U132 side of the pressing tool U130 along the length direction of the pressing tool U130 (the vertical direction in Figs. 20(a) and (b)) until it communicates with the through hole U134.

[0088] In this modification, the bent portion 1681 of the repulsive tool (kick spring) 168 is fitted into the guide rail 171 and slides inside the guide rail 171 while pressing the end portion on the contact portion U132 side on the front side of the pressing tool U130, while the end portion of the repulsive tool (kick spring) 168 opposite to the side on which the bent portion 1681 is formed is stopped by abutting against one inclined surface in the recessed groove 169. With this configuration, the elastic force of the repulsive tool (kick spring) 168 can act on the pressing tool U130.

[0089] For example, the rebounding member 168 made of a kick spring according to this modified example may be changed to a plate spring or the like.

[0090] (13) A further modified example of the drug applicator according to the present invention is shown in Fig. 21. The drug applicator V100 shown in this figure is provided with a finger contact portion 172 in addition to the same configuration as the drug applicator 100 according to the embodiment shown in Fig. 1.

[0091] In this modification, finger rests 172A and 172B are provided on the peripheral surface of the arm V10 at positions spaced slightly outward from the groove V232 in the length direction (the space may overlap the through hole of the pressing tool 130, but does not interfere with the operation of the pressing tool 130). Of the finger rests 172, the finger rest 172A on the extension part V14 side is formed with a finger rest surface 1721A that extends outward from the surface of the peripheral surface of the arm V10 opposite the base part 222 side (the upper side in FIG. 21(a)) so as to form a mountain shape with a rounded tip in a front view, and both side surfaces extend in an inclined manner from both oblique sides of the finger rest surface 1721A so as to converge at one point slightly spaced apart toward the groove 232 on the peripheral surface of the arm V10, and is molded as a whole into a three-dimensional shape that protrudes from the peripheral surface of the arm V10 in a substantially triangular pyramid shape. The ridgeline portion (intersection of both sides) that extends from the top of the finger rest 172A while slanting downward toward the groove V232 extends continuously from the tip of the finger rest 1721A while maintaining a round cross-sectional shape, and the tip where the ridgeline portion intersects with the peripheral surface of the arm V10 is also formed to be round in plan view. Also, as shown in Fig. 21(c), the finger rest 1721A is formed to be recessed outward from the peripheral surface of the arm V10 and generally slightly inward in a roughly arc-shaped round shape in side view.

[0092] In this modification, as shown in Fig. 21(c), by placing any finger (e.g., thumb) F1A on the finger contact surface 1721A of the finger contact portion 172A on the extension portion V14 side, placing the other finger (e.g., index finger) F2A on the front side of the knob of the pressing tool 130 on the gripping portion V11 side, and pinching with these fingers F1A and F2A, the pressing tool 130 on the gripping portion V11 side can be opened and closed. On the other hand, by placing any finger (e.g., index finger) F1B on the finger contact surface of the finger contact portion 172B on the gripping portion V11 side, placing the other finger (e.g., thumb) F2B on the front side of the knob of the pressing tool 130 on the extension portion V14 side, and pinching with these fingers F1B and F2B, the pressing tool 130 on the extension portion V14 side can be opened and closed. In this manner, by providing the finger contact portion 172, it becomes easy to individually open and close one of the pair of pressing tools 130, 130, improving operability.

[0093] The finger rests 172A and 172B may be individually molded and then joined to the circumferential surface of the arm V10 to be integrated, or may be molded integrally with the arm V10 at the same time. The shape of the finger rests may be any shape, such as a box shape, a column shape, a plate shape, a knob shape, etc., and may be configured such that at least a portion of the finger rest is extendable or may have a sliding structure that allows the finger rests to be slid in the longitudinal direction of the arm V11 to be adjusted to the width of individual fingers.

[0094] Needless to say, the finger rest portion can also be applied to other aspects of the medicine applicator, such as an aspect in which grip portions are provided at both ends of an arm.

[0095] (14) A further modified example of the medicinal applicator according to the present invention is shown in Fig. 22. The medicinal applicator W100 shown in this figure has an arm W10 provided with an auxiliary foot 173 for operating a pressing tool W130.

[0096] In this modification, the auxiliary foot 173 is provided at a position slightly closer to the gripping part W11 side than the concentration part W220 in the arm W10. The auxiliary foot 173 is a plate-like shape that gradually expands radially outward from the circumferential surface of the arm W10 in a roughly triangular shape when viewed from the front, and is formed so that the corners of both ends are rounded off. Also, as shown in Fig. 22(c), the auxiliary foot 173 is curved so that it bulges out slightly toward the gripping part W11 side in a roughly arc shape from both ends to the center when viewed from the bottom.

[0097] The auxiliary foot 173 is integrated with the peripheral surface of the arm W10. This integration may be achieved by joining it to the arm W10 or by simultaneously molding it as a single piece. However, in order to improve stability and prevent the auxiliary foot from being lost, it is preferable that the auxiliary foot is fixed to the arm W10 so that it cannot be attached or detached.

[0098] However, as shown in Fig. 23, for example, the arm W10a may be provided with a detachable part 174 to which the auxiliary foot 173a can be attached and detached. The detachable part 174 shown in the figure is configured by adhering or embedding a magnetic material at least on the surface of the arm W10a or inside the arm part, while at least a corresponding part (a part that abuts against the circumferential surface of the arm W10a) in the auxiliary foot 173a is also similarly configured with a magnetic material, so that the auxiliary foot 173a can be freely attached and detached to the arm W10a. Furthermore, for example, the arm and the auxiliary foot may be configured to be detachably connected to each other by a physical structure via a hole and a shaft without using a magnetic material.

[0099] This allows the auxiliary foot portion 173a to be removed when the user is using the drug applicator, making it possible to apply the drug without the auxiliary foot portion interfering with the clothing worn by the user.

[0100] The drug applicator W100 (and W100a) according to this modification can be supported by the tip edge of the auxiliary foot 173 and placed on a flat surface such as a floor surface. At this time, the center of gravity of the drug applicator W100 is located slightly closer to the grip part W11 side than the auxiliary foot 173, and therefore, the tip of the auxiliary foot 173 serves as a fulcrum, and the grip part W11 side end lowers and abuts against the flat surface, while the concentration part W220 rises up, resulting in an inclined position. Therefore, in this inclined position, the tip of the pressing tool W130 is always kept away from the flat surface. The applying member can be attached and detached while operating the pressing tool W130 without interfering with the flat surface, making it easy to attach and detach the applying member. Since the applicator body is away from the flat surface and does not interfere with it, the arm W10 and the auxiliary foot 173 can be set at any angle in the radial direction of the arm W10.

[0101] In addition, if the center of gravity is positioned differently, for example by providing gripping portions at both ends of the arm, the inclined position described above may not be achieved as is; however, even in such a case, the inclined position described above may be achieved by, for example, placing an appropriate weight on one end of the arm.

[0102] (15) Further modified examples of the drug applicator according to the present invention are shown in Fig. 24. The drug applicators Y100a and Y100b shown in the figure are provided with a self-supporting foot 175, with Fig. 24(a) showing an example in which a self-supporting foot 175a is provided at the end of the extension section Y14a, and Fig. 24(b) showing an example in which a self-supporting foot 175b is provided at the end of the grip section Y11b.

[0103] The self-supporting foot 175a shown in Fig. 24(a) is formed in a shape in which the diameter gradually expands from the end of the extending part Y14a of the round bar-shaped arm Y10a toward the outside to form a generally conical shape. That is, the upper surface is a circle of approximately the same dimensions as the cross section of the extending part Y14a of the arm Y10a, and the bottom surface is a circle of a larger diameter (larger area) than the cross section of the extending part Y14a, so that the self-supporting foot 175a is formed in a generally truncated cone shape. It is desirable that a part or all (at least a part) of the self-supporting foot 175a is made of a material having a higher specific gravity than the material of the arm Y10a (for example, a combination of the arm Y10a being ABS resin and the self-supporting foot 175a being lead). The self-supporting foot 175a may be formed integrally with the arm Y10a, or may be configured to be detachably attached to the arm Y10a by a magnetic body as in the case of the auxiliary foot 173a shown in Fig. 23, or may be configured to be detachable by a connection structure via a hole and a shaft. Furthermore, for example, at least the outer end surface (the lower end surface in Fig. 24(a)) of the self-supporting foot 175a may be configured to be magnetic so that it can be attached to a metal surface by magnetism during use, or attached to a surface by a suction cup.

[0104] The self-supporting foot 175b shown in FIG. 24(b) has a configuration basically similar to that of the self-supporting foot 175a shown in FIG. 24(a), but since it is provided on the gripping portion Y11b, which has a slightly larger diameter than other parts of the arm Y10b, the upper surface of the self-supporting foot 175b also has a slightly larger diameter.

[0105] The self-supporting feet may be provided at either end of the arm, or even at both ends, but in order to improve stability when the arm is self-supporting, it is preferable to provide the feet at least at the end of the arm where the center of gravity is located. In this case, the position of the center of gravity may be adjusted by using a weight or the like.

[0106] According to the medicine applicators Y100a and Y100b of this modification, the bottom surfaces of the self-supporting feet 175a and 175b can be placed so as to lean against a surface such as a floor surface, thereby making it easier to replace an applicator member such as a cotton puff, and is also advantageous for storing and safekeeping the medicine applicators Y100a and Y100b.

[0107] (16) 25 shows another example of the self-supporting foot, in which (a) the self-supporting foot 176 is provided at the end of the extension Z14a, and (b) the self-supporting foot 176 is provided at the end of the gripping part Z11b. The self-supporting foot 176 according to this modification can function in almost the same way as the self-supporting foot 175 according to the above modification (15).

[0108] Self-supporting foot 176 according to this modification has a configuration in which support shaft 176F is provided on base plate 176B. Base plate 176B is a rectangular plate that is disposed so as to lie flat on a surface, and round bar-shaped support shaft 176F extends upward from the center of the upper surface.

[0109] 25(a), a shaft hole 177a having a circular cross section is recessed from the center of the end face of the extension part 14a of the arm 10a so as to extend linearly along the axial direction of the arm 10a. The inner diameter and length (depth) of the shaft hole 177a are such that the support shaft 176F of the base plate 176B can be easily inserted or removed, and the support shaft 176F can be held inside without rattling.

[0110] The drug applicator Z100b shown in Figure 25(b) has the same configuration as the drug applicator Z100a shown in Figure 25(a), except that the shaft hole 177b is provided at the side end of the gripping portion Z11b, and the same self-supporting foot 176 can also be used.

[0111] The drug applicators Z100a, Z100b of this modified example, like the drug applicators Y100a, Y100b of modified example (15) above, have a simple structure and can be easily maintained in a free-standing position, and in addition, the free-standing foot 176 can be easily attached and detached.

[0112] (17) The self-supporting foot may also have a configuration as shown in Fig. 26. The self-supporting foot 178 according to this modification is adapted to grip and hold the arm P10 of the drug applicator P100 from the outside, and in Fig. 26(a) it grips the end of the arm P10 on the side of the extension part P14, and in Fig. 26(b) it grips the end of the arm P10 on the side of the grip part P11.

[0113] The self-supporting foot 178a shown in Fig. 26(a) is molded into a rectangular parallelepiped shape, and a support hole 179a is provided in the center of the upper surface, which allows the extension part P14 side end of the arm P10 to be easily inserted or removed and can be held inside without rattling. The self-supporting foot 178b shown in Fig. 26(b) has the same configuration as the self-supporting foot 178a shown in Fig. 26(a), except that the support hole 179b has a slightly larger diameter corresponding to the grip part P11 side end.

[0114] The self-supporting feet 178 (178a, 178b) according to this modification can function in substantially the same manner as the self-supporting feet 176 according to the above modification (16).

[0115] (18) A further modified example of the drug applicator provided with a self-supporting foot is shown in Figure 27. The drug applicator K100 shown in the figure is provided with a self-supporting foot 180 at the end of the arm K10 on the side of the gripping part K11, and the gripping part K11 has a configuration similar to that of the gripping part 911A according to the modified example shown in Figure 14. The self-supporting foot 180 is formed further towards the tip side than the gripping part K11, so as to have a generally conical shape that gradually widens in diameter towards the tip.

[0116] (19) A further modified example of the drug applicator provided with a self-supporting foot is shown in Figure 28. The drug applicator J100 shown in this figure is basically the same as the drug applicator 100 according to the embodiment shown in Figure 1, except that a self-supporting foot 181 is provided at the end of the arm J10 on the extension J14 side. The self-supporting foot 181 is formed by molding the end of the arm J10 on the extension J14 side into a generally conical shape with the diameter gradually increasing towards the tip.

[0117] (20) The configuration of the self-supporting foot may be, for example, similar to the case of the self-supporting foot 175 of the above-mentioned modified example (15), configured to be magnetic so as to be attached to a metal surface magnetically, or configured to be attached to a surface with a suction cup.

[0118] (twenty one) Further modified examples of the drug applicator according to the present invention are shown in Fig. 29. The drug applicator H100 shown in Fig. 29 (a) is provided with a low-rigidity section 182 having a relatively low rigidity on an arm H10, and Figs. 29 (b) to (e) are diagrams specifically showing various configuration examples of the low-rigidity section 182.

[0119] As shown in FIG. 29(a), the low-rigidity portion 182 is provided at a position between the concentrated portion H220 and the gripping portion H11 in the arm H10, and slightly closer to the concentrated portion H220. As a more specific configuration example, the low-rigidity portion 182b shown in FIG. 29(b) is formed by reducing the cross-sectional area at this portion of the arm H10. Furthermore, for example, instead of or in addition to reducing the cross-sectional area in this way, this portion of the arm H10 may be made of a material with a relatively low rigidity (e.g., polyethylene, etc.). The low-rigidity portion 182c shown in FIG. 29(c) is formed in such a way that this portion of the arm H10 is bellows-shaped. The low-rigidity portion 182d shown in FIG. 29(d) is formed in such a way that this portion of the arm H10 is wavy or has a continuous S-shape (serpentine shape). The low-rigidity portion 182e shown in FIG. 29(e) is formed by sandwiching and gluing a filling material (e.g., liquid silicone rubber, etc.) 183 into the gap formed by the wavy shape of the low-rigidity portion 182d shown in FIG. 29(d).

[0120] The low rigidity portion 182 according to this modification reduces the rigidity of the arm H10 at this portion to provide flexibility, thereby reducing the burden on the wrist and arm of the user.

[0121] When a low-rigidity portion is provided, it may be provided on a part of the arm H10 as in this modified example, or on the entire arm. In other words, it is sufficient to provide the low-rigidity portion on at least a part of the arm.

[0122] In addition, in the drug applicator H100 according to this modification, a low-rigidity layer 184 may be provided on the use surface (the surface that comes into contact with the body of the user) of the base part H222, and the low-rigidity layer 184 is formed by applying a low-rigidity material such as liquid silicone rubber to the use surface of the base part H222. This low-rigidity layer 184 also reduces the hardness and burden on the user's skin. When such a low-rigidity layer is provided, it may be provided on the entire base part, in other words, it may be provided on at least the use surface of the base part.

[0123] (twenty two) A further modified example of the drug applicator according to the present invention is shown in Fig. 30. In the drug applicator G100 shown in the figure, the pressing tool G130 has a structure such as a through hole G134 similar to that of the pressing tool 130 according to the embodiment shown in Fig. 1, and is similarly attached to the arm G10 so as to be able to swing, but both sides of the abutment part extend so as to wrap around to the side parts of the base part G222, thereby forming extension pieces G139.

[0124] In this modification, as shown in Fig. 30(c), the base portion G222 is formed into a roughly octagonal shape in which the four corners of the square are cut off to form oblique sides, i.e., a three-dimensional shape consisting of eight side surfaces, a top surface, and a bottom surface, for a total of ten surfaces. Meanwhile, the extension piece G139 of the pressing tool G130 according to this modification extends obliquely along the side surfaces of the four corners of the base portion G222 so as to expand outward in bottom view, and the contact portion as a whole has a roughly angular arch shape in bottom view.

[0125] According to the extension piece G139 of this modified example, since it has an outwardly expanding shape as described above, it can be easily and reliably pressed against the side surface of the base portion G222 without being concerned about the position.

[0126] The shape of the contact part including the extension piece can be various shapes such as an approximately squared arch shape when viewed from the bottom as described above, an approximately U-shape when viewed from the bottom, an approximately C-shape when viewed from the bottom, an approximately arc shape (arch shape) when viewed from the bottom, etc., and the shape of the base part may be formed in a shape that generally follows the shape of the base part side of the contact part. The shape of the base part may also be a shape such as an approximately cylindrical body or an elliptical cylinder, which can be more suitable for the skin surface of the user.

[0127] The above embodiments are illustrative and not limiting, and the scope of the present invention is defined by the appended claims. [Industrial Applicability]

[0128] The present invention is applicable to, for example, a drug applicator for applying a drug or cosmetic, a drug application kit, and a pressing tool for a drug applicator. [Explanation of symbols]
