Abstract

PROBLEM TO BE SOLVED: To provide a suction tool for skin which features high durability and a great suction power without being bulky, and can be easily cleaned and dried. SOLUTION: By enclosing a pimple with a suction mouth 11a, and pulling up a piston rod 13 to move a piston 12 to the rear side of a cylinder 11, pus comes out of the pimple due to the depressurized air before the piston 12 within the cylinder 11. Such cylinder system like this improves the durability compared with the conventional rubber-ball suction system. Moreover, in this system, the suction power can be increased by an inexpensive and non-bulky method merely pulling up the piston 12 to a large extent not by replacing the rubber ball, in the rubber-ball system, with a new larger, more bulky, and expensive ball. In addition, in the cylinder system, it is easier to clean or dry it afterwards.

By the way, this conventional skin inhaler has the following drawbacks. (1) A rubber ball 102 is used as a suction force (negative pressure) generating portion.
However, if the rubber balls 102 are used for a long period of time or repeatedly washed with water after use, the rubber balls 102 may deteriorate. Moreover, it is difficult to clean the inside of the rubber ball 102, and in many cases, the subsequent drying cannot be sufficiently performed. As a result, the deterioration of the rubber ball 102 has stopped. (2) According to the conventional skin suction device 100, the pus is sucked out from the acne by utilizing the elastic force of the crushed rubber ball 102. Therefore, in order to generate a large suction force, an expensive large rubber ball 102 has to be used. As a result, the inhaler 100 for skin is bulky and costly.

[0004] Therefore, as a result of earnest research, the inventor of the present invention can improve the durability of the skin aspirator if the skin aspirator is a cylinder-structured aspirator that does not use rubber balls, and is compact.

Is. The material of the cylinder is not limited. Examples thereof include synthetic resins such as polyethylene, polyvinyl chloride and polypropylene, metals such as stainless steel and aluminum, and glass. The cylinder may be opaque, but it is preferable that the cylinder is transparent or semi-transparent because the suctioned substance and the suctioned state can be visually recognized. The cross-sectional shape of the cylinder is not limited. For example, a circular shape, an elliptical shape, a triangular shape, and a polygonal shape including a quadrangle or more may be used. The length of the cylinder is not limited. However, about 3 to 15 cm is easy to use. This skin aspirator may be manual or automatic. In the automatic type, the piston rod can be reciprocated by an electric motor via, for example, a crank mechanism. In addition, the piston is reciprocated by alternately supplying working fluid (air, inert gas, water, oil, etc.) to the part on the front side of the piston and the part on the back side of the piston in the internal space of the cylinder. You may.

The invention according to claim 2 is the skin inhaler according to claim 1, wherein a grip portion is formed at a portion of the piston rod connected to the piston, the portion protruding outward from the cylinder. The grip portion may be formed on the end portion of the piston rod or may be formed on the middle portion of the piston rod. The shape of the grip is not limited. For example, it may have a flange shape or a ball shape.

According to the present invention, the piston is arranged in advance near the suction port of the cylinder, and in this state, the suction port is applied to a predetermined part of the skin, for example, around the acne. After that, the pressed state is maintained, and for example, the grip portion formed on the piston rod is gripped (claim 2) and moved to the rear side of the cylinder. As a result, the piston moves to the rear side of the same cylinder in the cylinder, and the space on the front side (suction port side) of the piston in the cylinder becomes negative pressure. As a result, acne pus and the like are sucked into this space. In this way, since the cylinder type skin suction device is adopted, the durability is improved as compared with the conventional skin suction device using a rubber ball that easily deteriorates. Moreover, by increasing the size of an expensive and bulky rubber ball as in the conventional case, it is possible to generate a large suction force only by increasing the moving distance of the piston, instead of increasing the suction force. Furthermore, since it is a cylinder type, cleaning and subsequent drying are easy.

According to the third aspect of the present invention, since the piston is composed of a plurality of partial pistons separated from each other by a predetermined length, the fulcrum of the piston rod in the cylinder is a plurality of positions separated from each other. Therefore, for example, when sucking pus from an acne, even if the direction of the force acting on the piston rod is slightly deviated from the moving direction of the piston, the piston is less likely to rattle in the cylinder.

According to the fourth aspect of the present invention, for example, if the force acting on the piston is released after the acne is sucked out, the piston returns to the front side in the cylinder by the elastic force of the elastic member. As a result, it is not necessary to apply a predetermined external force after use to move the piston to the original position of the cylinder.

According to the invention of claim 5, when a finger is hooked on the finger hook member and the finger hook member is slid along the slide hole toward the rear side of the cylinder against the elastic force of the elastic member, it is integrated with the piston rod. The piston moves to the rear side of the cylinder. As a result, the space in the cylinder ahead of the piston becomes negative pressure, and, for example, pus is sucked out from the acne to which the suction port is applied. Then, when the finger is released from the finger hook member, the piston automatically returns to the original position on the tip side in the cylinder due to the elastic force of the elastic member. Thereby, for example, when the skin suction device is reused, it is not necessary to apply a predetermined external force to return the piston to the original position. As described above, since the skin suction device can be used with one hand by utilizing the elastic force of the elastic member, one hand can be freely used during use.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. First, a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows the first aspect of the present invention.
FIG. 6 is a perspective view of a usage state of the skin inhaler according to the example of FIG. FIG. 2 is a perspective view of the skin inhaler according to the first embodiment of the present invention. FIG. 3 is a longitudinal sectional view of the skin inhaler according to the first embodiment of the present invention. 1 to 3, reference numeral 10 denotes a skin suction device according to the present invention. The skin suction device 10 includes a cylinder 11 having a skin suction port 11a formed on a distal end surface thereof, and a piston that reciprocates in the cylinder 11. 1
2 and a piston rod 13.

The cylinder 11 is a small-diameter cylindrical body made of transparent polypropylene and having both ends opened. Piston 12
Is the end piston 12A and the intermediate piston 12B.
It consists of a piece of partial piston. The tip piston 12A is integrally formed at the tip of the piston rod 13. on the other hand,
The intermediate piston 12B is integrally formed near the intermediate portion of the piston rod 13. A flange-shaped grip portion 14 is integrally formed at the end of the piston rod 13 on the base side. These tip piston 12A and intermediate piston 12
B, the piston rod 13, and the grip 14 are each made of opaque polypropylene containing a colorant. An annular rubber packing 15 is attached to the outer peripheral portion of the tip piston 12A. The piston rod 13 is slightly longer than the cylinder 11.

Next, a method of using the skin suction device 10 according to the first embodiment will be described. As shown in FIG. 1, the piston rod 13 is pushed into the cylinder 11 in advance, and the tip piston 12A is moved to the suction port 11a of the cylinder 11.

Apply the suction port 11a around the acne. After that, the grip portion 14 is gripped, and the piston rod 13 is pulled integrally with the pistons 12A and 12B in the direction opposite to the suction port 11a. Then, the space in front of the tip piston 12A in the cylinder 11 becomes negative pressure, and the area around the acne is sucked into this space. As a result, the pus accumulated inside the acne is sucked out. To increase this suction force, pull the piston rod 13 strongly to
The moving distance of 2 should be lengthened. That is, the suction force for acne can be increased by using the same skin suction device 10 without replacing with an expensive and large rubber ball unlike the conventional product.

After use, the cylinder 11 is removed from the cheek. In this case, the pulling force of the piston rod 13 may be relaxed to return the negative pressure inside space of the cylinder 11 to normal pressure once, and then the cylinder 11 may be removed from the cheek. others,
While pulling the piston rod 13 to maintain the negative pressure,
By forcibly pulling up the cylinder 11 diagonally upward,
The cylinder 11 may be pulled away from the cheek. This way
There is no risk that the pus that once emerged will push back into the acne. Further, when the cortex accumulated in the pores is sucked out instead of a pimple such as acne, the same operation can be performed to suck out the cortex. To clean the skin suction device 10,
The piston rod 13 with the piston 12 is pulled out from the inside of the cylinder 11, and the skin suction device 10 is disassembled. As a result, this cleaning and the subsequent drying become easy.

As described above, since the cylinder type skin suction device 10 is adopted, higher durability can be obtained as compared with the conventional skin suction device using a rubber ball which easily deteriorates. Further, since the piston 12 is composed of the tip piston 12A and the intermediate piston 12B which are separated from each other by a predetermined length, for example, when sucking pus from an acne, the direction of pulling the piston rod 13 is the moving direction of the piston 12. Even if there is a slight deviation, the fulcrum of the piston rod 13 in the cylinder 11 is at two spaced locations. Therefore, the tip piston 12A and the intermediate piston 12B that are moving are less likely to rattle in the cylinder 11.

Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 4 is a longitudinal sectional view showing a usage state of the skin inhaler according to the second embodiment of the present invention. The skin suction device 20 according to the second embodiment automatically moves the piston 12C to the cylinder 11 by the force of the spring after sucking out acne.

A flange-shaped contact plate 13a is provided at the base of the. Near the base of the piston rod 13A, an intermediate portion in the length direction of a finger hook member 22 for operating the piston rod 13A with a fingertip is detachably fixed. The finger hooking member 22 is rod-shaped, and both ends of the finger hooking member 22 project from the slide holes 11d, 11d toward the outside of the cylinder 11A. The moving distance of the piston 12C is determined by the lengths of these slide holes 11d and 11d. Here, the finger hook member 22 is used for both slide holes 11
The lengths of both slide holes 11d and 11d are determined such that the tip end surface of the piston 12C is arranged at the suction port 11a when abutting on the cylinder front ends of d and 11d. Further, the cover plate 13a and the cover plate 11 in the cylinder 11A are
Between piston rod 13A and cylinder 11A

The space in the cylinder 11A ahead of the piston 12C becomes negative pressure, and the pus accumulated inside the acne is sucked out. When the piston rod 13A moves, the cylinder 11
The air between the cover plate 13a and the cover plate 11b in A is discharged from the air vent hole 11c.

After use, when the two fingers are released from the finger-holding member 22, the elastic force of the coil spring 23 automatically pushes the piston 12C together with the piston rod 13A back to the vicinity of the suction port 11a. As a result, after using the skin suction device 20, it is not necessary to apply a predetermined external force to move the piston 12C to the original position of the cylinder 11A. At the time of washing, if the finger hook member 22 is pulled out from the piston rod 13A, the skin suction device 20 can be disassembled and easily washed with water. As described above, the elastic force of the coil spring 23 is used to allow the skin suction device 20 to be used with one hand, so that the other hand can be freely used during use. Other configurations, actions and effects are
The description is omitted because it is substantially the same as the embodiment described above.
