Abstract

PROBLEM TO BE SOLVED: To improve a weight reduction treatment effect, etc., by supplying a lot of optical energy to acupoints, etc., having e.g. a weight reduction effect, without giving uncomfortable feeling to a user. SOLUTION: Since a laser treatment device 1 provided with a laser beam irradiator 5 supplies laser beams to the skin 46 from a light emitting part 23 at the tip of a light guiding lens 22 in contact with a skin 46, thermesthesia and a pain sensation such as hotness, pain, etc., on the skin 46 caused by laser beam irradiation is made dull by the sense of touch caused by the contact of the part 23 with the skin 46 and these senses of hotness, pain, etc., are reduced. Since the epiderm layer of the skin 46 is expanded thinly along the spherical surface of the part 23 by the irradiator 5, the power of the laser beams which have to reach acupoints 47 existing in the depth of the skin 46 is prevented from being lost remarkably due to the epiderm layer. Thus, a lot of the optical energy can be supplied to the acupoints and the metabolism of the human body is improved to improve the weight reduction treatment effect.

[0002]

2. Description of the Related Art In general, since laser light has a higher energy density than other light, when a living tissue is irradiated, the irradiated portion of the living tissue can be heated to a high temperature. It can induce so-called photothermal reactions that intentionally cause denaturation of proteins at desired sites, and non-thermal reactions that promote metabolic functions, that is, photochemical reactions, photomagnetic reactions, ionization reactions, etc. It is.
Therefore, the laser treatment apparatus is designed to perform, for example, hair removal or hair restoration treatment by irradiating a laser beam to the skin of a human body by appropriately setting a laser power, an irradiation time, and the like according to an application.

[0003] That is, a laser treatment device is
By irradiating a hair root such as body hair to be depilated with a laser beam having a relatively high energy density, a photothermal reaction is induced to promote denaturation of the protein of the hair mother cell, thereby realizing the hair removal treatment. In addition, the laser treatment device irradiates a hair root such as the hair of a hair growth target with a laser light having a relatively low energy density to induce a non-thermal reaction, thereby promoting blood circulation and metabolism of hair mother cells, thereby performing hair growth treatment.

[0004] The laser treatment apparatus is also applied as an apparatus for performing beautiful skin or slimming. That is, when performing a beautiful skin, the laser treatment device irradiates the melanin scattered on the epidermis and the dermis of the skin with a laser beam, causes thermal denaturation by photothermal action, and removes aza, spots, freckles, and the like. Furthermore, when performing a slimming, the laser treatment device supplies a laser beam to a specific acupoint closely related to the sympathetic nerve, stimulates the acupoint by a non-thermal action to promote blood circulation, thereby activating cell tissues. Increases metabolic function and burns excess fat.

As described above, in a conventional laser treatment apparatus capable of performing various treatments, generally, laser light emitted from a semiconductor laser diode is condensed by a spherical lens, and the laser light is applied to the skin from a position separated from the skin surface. There are many types in which irradiation is performed toward various treatments.

[0006]

By the way, in such a laser treatment apparatus, it is desirable to supply a laser beam having relatively high power to the skin in order to enhance the treatment effect. There are the following restrictions on the setting of the power.

[0007] That is, in the laser treatment apparatus, it is a general setting condition of the laser power that the user does not give the user unpleasant sensation such as heat or pain exceeding the limit due to the laser light applied to the skin.

However, in the conventional laser treatment apparatus having the above-described structure, when a high treatment effect is to be obtained, the power of the settable laser beam cannot be said to be, of course, satisfactory with the current apparatus. Improvements in this regard are required.

[0009] Further, in the conventional laser treatment apparatus, for example, when performing slimming, when the laser beam to reach the acupoint located in the back of the skin is largely obstructed by the epidermis layer, and when the laser beam reaches the acupoint, There is also a problem that the amount of laser light (the amount of heat, etc.) is reduced, and a desired treatment effect cannot be obtained.

Therefore, the present invention has been made to solve the above-mentioned problem, and does not give any discomfort to the user.
An object of the present invention is to provide a laser treatment device capable of enhancing a treatment effect by supplying a large amount of light energy to a desired part of a human body.

[0011]

In order to achieve the above object, a laser treatment apparatus according to the present invention comprises a light emitting element for emitting laser light, and a light transmitting element for guiding the laser light emitted from the light emitting element side. And a light emitting unit provided on the transmitting body, which is pressed against the skin of a human body and emits the laser light guided from the light emitting element to act on the skin. And

In the laser treatment apparatus according to the present invention, since the laser beam is supplied to the skin from the light emitting portion of the transmitting body brought into contact with the skin, it is possible to sense that the light emitting portion of the transmitting body is in contact with the skin (tactile sensation). ) Can reduce the sensation (warmth or pain sensation) such as heat and pain on the skin due to the irradiation of the laser beam, and can alleviate the sensation such as heat and pain.

The laser beam can be condensed by using the spherical shape of the light emitting part, and the skin layer of the skin can be expanded (thinned out) according to the spherical shape of the light emitting part. In such a case, it is possible to suppress that the power of the laser beam to reach the acupoint located in the back of the skin is largely lost by the epidermis layer.

Therefore, according to the laser treatment apparatus of the present invention, since a large amount of light energy can be supplied to, for example, acupoints having a slimming effect, these acupoints are strongly stimulated by a high photothermal reaction to promote blood circulation, thereby enhancing metabolic functions. It is possible to improve the treatment effect.

Further, the laser treatment device according to the present invention further comprises a touch sensor for detecting contact / non-contact of the light emitting section with the skin, and the light emitting element from the light emitting element based on a detection result by the touch sensor. Means for controlling emission / non-emission of laser light.

According to the laser treatment apparatus according to the present invention, it is possible to control so as not to irradiate the laser light except when the light emitting section is in contact with the skin. This can be suppressed, and the safety of the device can be improved.

The laser treatment device according to the present invention may further comprise a first electrode provided so as to be able to come into contact with the skin in the vicinity of the light emitting section, and a predetermined position different from the vicinity of the light emitting section. A second electrode provided so as to be able to come into contact with the skin, and a resistance detection for detecting a resistance value by flowing a current between the electrodes while the first and second electrodes are in contact with the skin. And a means for detecting a position of an acupuncture point in the human body based on a detection result by the resistance detecting means.

In the laser treatment apparatus according to the present invention, while the light emitting portion provided with the first electrode in the vicinity is moved on, for example, the skin, the first electrode and a position different from the vicinity of the light emitting portion, for example, A portion having a lower resistance value than other portions, that is, a human body, is measured by flowing a current between the second electrode provided so as to be in contact with the skin at a portion where the device body is gripped and the like, and measuring the resistance value. Can be detected.

Here, when a transmissive body having a spherical surface of the light emitting portion is applied, the skin layer of the skin can be thinly extended in accordance with the spherical shape of the light emitting portion. Is more accurate, and the accuracy of detecting the position of the acupoint can be improved.

As described above, according to the laser treatment apparatus of the present invention, when performing slimming, for example,
As it can detect the position of the acupoint with the slimming effect and can supply a lot of light energy to this detected acupoint,
Acupoints can be strongly stimulated by a high photothermal reaction to promote blood circulation, thereby increasing metabolic functions and improving the treatment effect.

Further, in the laser treatment apparatus according to the present invention, the transmission member formed in a rod shape, the transmission member formed in a rod shape having a bent portion, and the plurality of transmission members having different radii of curvature of the light emitting portion are provided. And any one of these transmissive members can be selectively mounted on a housing in which the light emitting element is mounted.

According to the laser treatment apparatus of the present invention, a rod-shaped transmissive body or a rod-shaped transmissive body bent within a range in which laser light emitted from the light emitting element is totally reflected, for example, is used. Thus, a large amount of laser light can be reliably supplied to all parts of the human body, and a high torment effect can be exhibited.

Further, according to the laser treatment apparatus of the present invention, by selectively using the transmissive members having different radii of curvature of the light-emitting portion, for example, the type of treatment such as hair removal, hair growth, beautiful skin, or slimming can be reduced. Accordingly, the focusing position of the laser beam can be freely changed. Thereby, it is possible to supply the optimal leather power to a desired part of the human body, and it is possible to improve the torment effect.

It should be noted that in the present invention, the sense of warmth or pain such as heat or pain on the skin due to laser beam irradiation is blunted by the above-mentioned tactile sensation in which the light emitting portion of the transmitting body is in contact with the skin. Then, in order to increase the tactile sensation, it is desirable to minimize the radius of curvature of the light emitting section. Further, it is preferable that the transmitting body having such a light emitting section is formed of quartz or the like which is relatively hard and has excellent transparency, but an optical fiber or the like having flexibility in consideration of workability at the time of tormentation and the like. May form a transmission body.

And a setting switch 10 for adjusting a laser light output, setting an irradiation time, setting a treatment time, and setting a mode such as a laser light irradiation mode or an acupoint detection mode, and an LED 11 indicating each setting state.

Further, as shown in FIGS. 2 and 3, the laser beam irradiation device 5 is a hand-held device for performing a treatment by holding it by hand, and a case 12 having a handling unit 14 to be gripped by the user. A control chip 16 and a fan 17 mounted inside the case 12 via a substrate 15; an LED lamp 18 and a push switch 19 provided on the surface of the case 12; A semiconductor laser diode 20 that emits light, a heat sink 21 that removes heat from the semiconductor laser diode 20 while being constantly cooled by the fan 17, and a transmissive body that is detachable from the case 12. A light guide lens formed of, for example, quartz or the like, for guiding the laser light emitted from It is mainly composed of 22 Metropolitan.

The heat sink 21 diffuses heat generated during the operation of the semiconductor laser diode 20 by heat conduction, thereby suppressing a decrease in performance. For this reason, it is cast with aluminum or an alloy thereof having good heat conduction efficiency, and several dummy through holes are provided to increase the surface area to enhance the heat radiation efficiency.

The semiconductor laser diode 20 is made of GaAs
(G) using compound semiconductors such as gallium arsenide
A laser is oscillated by passing a current directly through the N-junction diode for excitation. Further, the semiconductor laser diode 20 outputs laser light having a peak wavelength of 600 to 1600 nm and an optical output of 5 mW or more, and such laser light has good thermal efficiency and causes a sufficient photothermal reaction on the skin.

Further, such a laser beam has an effect of inducing not only a photothermal reaction, but also a photoelectric reaction, a photomagnetic reaction, a photodynamic reaction, a photochemical reaction, a photoimmune reaction, a photoenzymatic reaction, and the like.

I have. The light emitting section 23 is used in a state of being in contact with the skin when performing a treatment, and has a spherical outer shape so as to collect laser light.

In the light emitting section 23 used in a state of contact with the skin, the sensation such as heat and pain on the skin due to the irradiation of the laser beam is reduced by the tactile sensation that the light emitting section 23 is in contact with the skin. It has the function of relieving heat and pain. In addition, since the light emitting unit 23 can spread (elongate and thinly) the epidermis layer of the skin according to its spherical shape, for example, the power of the laser beam to reach the acupoint at the back of the skin is reduced. Significant loss due to the layer can be suppressed.

Further, the light emitting section 23 focuses the laser beam of the semiconductor laser diode 20 to form a forward focal point. However, since the focal length is shorter than that of a normal lens, the focal depth is slightly reduced to a narrow range. Power can be narrowed down. The laser beam condensed by the light emitting unit 23 spreads at the same angle from the position beyond the focal point, and the optical power is dispersed over a wide range. For this reason, at a position beyond the focal point, the energy density is reduced and the optical power is reduced, so that even if an unintended part of the living body is erroneously irradiated, the possibility of damaging the living body is reduced.

Further, the light guide lens 22 having such a light emitting portion 23 is placed between the green portion of the light emitting portion 23 at the tip of the light guide lens 22 so as to sandwich the laser light irradiation port.

The touch sensor circuit 27 reads the voltage values of the contacts 24 and 25 and determines whether or not a predetermined AC voltage is generated.
When a predetermined AC voltage is generated in both of the circuits 5, an ON signal is output to the drive circuit 32 of the semiconductor laser diode 20.

The drive circuit 32 turns on and off the semiconductor laser diode 20 based on commands from both the touch sensor circuit and the timer control circuit. That is, the drive circuit 32 turns on the semiconductor laser diode 20 for the first time when both the touch sensor circuit and the timer control circuit output an ON signal. Therefore, when the touch sensor circuit 27 does not output the ON signal, the semiconductor laser diode 20 is not turned on even if the timer control circuit outputs the ON signal. The LED lamp 18 has red and green L
The ED chip is put in one lamp, and one or both of them are simultaneously lit to emit light of three colors of red, green, and orange (amber).

The push switch 19 is used to perform an operation of switching on / off of the power and on time of the intermittent irradiation. Each time the push switch 19 is pressed, the mode is switched in the order of power-on, on-time switching (1 second to 60 seconds), and power-off.

(5 seconds), the power is turned off, and the irradiation of the laser beam is stopped.

The acupoint detection circuit 28 detects an acupoint by utilizing the fact that the resistance value of the acupoint is lower than other parts when a weak current is applied to the human body.

And a notification circuit 45 for generating a notification sound such as an alarm via the speaker 43 (see FIG. 2) when a point is detected.

The laser laser treatment apparatus 1 of the present embodiment is provided with such an acupoint detecting circuit 28, and moves the light emitting portion 23 of the light guide lens 22 on the skin to thereby reduce the resistance of the human body. It is possible to detect a position having a low value, that is, a position of an acupoint located in a human body.

The contacts 24 and 25 are provided at positions sandwiching the light emitting portion 23 of the light guide lens 22, that is, at positions slightly shifted from the center of the light emitting portion 23, as described above. Therefore, the contact 2 is so positioned that the pot can be detected at a position exactly facing the light emitting section 23 at the tip of the light guide lens 22.
Each of the contact points 4 and the contacts 25 is connected to the acupoint detection circuit 28 while being continuously switched, and each resistance value is measured. The position information of the acupoints obtained thereby is reflected on the detection result of the acupoint detection circuit 28. Is also good.

Next, the operation in the case where the treatment is actually performed using the laser treatment apparatus 1 according to the present embodiment configured as described above will be described. In the present embodiment, a case where a slimming treatment is performed will be described. The light emitting portion 23 at the tip of the light guide lens 22 is formed as a spherical surface where the laser light emitted toward the skin focuses at a position of an acupoint having a slimming effect at a position deeper than the epidermis, for example.
