Abstract

A skin care apparatus suitable for use in proximity to a subject's eyes. The apparatus includes a treatment device and a stimulus device. Upon activation by a user, such as the subject or a technician, a stimulus delivered by the stimulus device causes the subject's eyelid to close prior to the administration of a skin care treatment by the treatment device.

Description

BACKGROUND

Skin surrounding the eye is commonly covered with various cosmetics such as eye liner, base coatings, coloring, etc. Such coatings must be removed periodically, and removal techniques typically involve the manual application of chemicals, usually with a cotton pad or facecloth. These cleaning chemicals are not intended for direct exposure to sensitive eye tissues and it is normal for people to close their eye-lids to prevent exposure during cosmetic cleaning around the eye.

Increasingly, the skin surrounding the eye is also a target of cosmetic treatments for conditions such as wrinkle reduction, “bags” or dark circle reduction, and other skin color and texture conditions concerning the skin adjacent the eyes. These treatments can include sprays, sonic cleansing, microdermabrasion, light, and the like. These treatments are less predictable to use than a facecloth, and therefore, could accidentally be activated while the eye is still open.

DETAILED DESCRIPTION

The detailed description set forth below in connection with the appended drawings where like numerals reference like elements is intended as a description of various embodiments of the disclosed subject matter and is not intended to represent the only embodiments. Each embodiment described in this disclosure is provided merely as an example or illustration and should not be construed as preferred or advantageous over other embodiments. The illustrative examples provided herein are not intended to be exhaustive or to limit the claimed subject matter to the precise forms disclosed.

The following discussion provides examples that relate to skin care. In particular, some examples described herein are directed to skin care devices that provide techniques for forcing the eye lids of a subject to close just prior to the administration of a skin care treatment. The skin care treatments can include but are not limited to cosmetic cleaning around the eye, laser treatment, ultrasound, microdermabrasion, etc. In the examples that follow, the devices and methods employ techniques that stimulate the eye's natural blink reflex. This stimulus can be a flash of light, a puff of air, a burst of sound or pressure, though other stimulus techniques could be used.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments of the present disclosure. It will be apparent to one skilled in the art, however, that many embodiments of the present disclosure may be practiced without some or all of the specific details. In some instances, well-known process steps have not been described in detail in order not to unnecessarily obscure various aspects of the present disclosure. Further, it will be appreciated that embodiments of the present disclosure may employ any combination of features described herein.

Turning now to FIG. 1, there is shown one example of a skin care apparatus generally designated 20, formed in accordance with aspects of the present disclosure. The skin care apparatus 20 is suitable for use in proximity to a subject's eyes. As shown in FIGS. 1 and 2, the apparatus 20 includes an ergonomic body 24, the rearward portion of which forms a handle 28. A treatment head 32 is disposed at the forward end of the body 24. The treatment head 32 includes a treatment applicator 36 that administers a treatment to a skin region adjacent to or surrounding the subject's eye, and a stimulus applicator 40 that administers a stimulus in order to stimulate the eye's natural blink reflex. As will be described in more detail below, upon activation by a user, such as the subject or a technician, the stimulus delivered by stimulus applicator 40 causes the subject's eyelid to close prior to the administration of a skin care treatment by the treatment applicator 36. In some embodiments, the stimulus delivered by stimulus applicator 40 causes the subject's eyelid to close just prior to the initiation and/or administration of a skin care treatment by the treatment applicator 36. In these or other embodiments, the administration of the stimulus continues throughout the duration of the skin care treatment. As a result of these aforementioned embodiments, a subject's eye-lids are forced close to prevent exposure during the skin care treatment.

Still referring to FIGS. 1 and 2, the body 24 houses the operating structure of the appliance. As shown in block diagrammatic form in FIG. 2, the operating structure in one embodiment includes a treatment unit 52, a stimulus generator 56, a power source 60, such as a rechargeable battery, and a treatment control 64. The treatment unit 52 in conjunction with the treatment applicator 36 forms a treatment device 68 and the stimulus generator 56 in conjunction with the stimulus applicator 40 forms a stimulus device 70. In some embodiments, a power cord coupled to the power supply supplies power via a “mains” power source.

The treatment control 64 includes an on/off button configured and arranged to selectively deliver power from the power source 60 to the treatment device 68 and the stimulus device 70. In some embodiments, the treatment control 64 may also include a treatment switch 74 coupled to control circuitry, such as a programmed microcontroller or processor, which is configured to control the administration of the stimulus by the stimulus device 70 and the skin care treatment by the treatment device 68. In some embodiments, the treatment control 64 includes a timer 80, which can be circuitry based or software based. The timer, when initiated by the treatment switch 74, assures that the administration of the stimulus precedes the administration of the treatment by a sufficient amount (e.g., approximately 80 milliseconds or greater). In other words, the timer 80, in conjunction with the treatment control 64, is programmed to, or comprises logic that, first causes administration of the stimulus to occur and then shortly thereafter, causes the administration of the skin care treatment to occur.

In some embodiments, the stimulus device 70 can administer a stimulus that includes but is not limited to a flash of light, a puff of air, a burst of sound or pressure, etc., that causes the subject's eye to close. In the embodiment shown in FIGS. 1 and 3, the stimulus device 70 administers a puff of air. The puff of air can be generated by any suitable mechanism, including a fan, a blower, a piston, a piezoelectric device, a pump, compressed gas, among others. The air can be supplied through one or more vents 94 in the body 24.

In the embodiment shown in FIG. 3, the stimulus generator 56 of the stimulus delivery device 70 includes a piezoelectric fan 86 operatively mounted in a chamber 90. A vent or other inlet/outlet 94 is positioned adjacent the fan 86 so that movement of the fan 86 draws air into the chamber 90 from exteriorly of the body 24, directs the air through the chamber 90, and discharges the air out of the stimulus applicator 40, which can include an outlet 96. In some embodiments, the fan 86 and the outlet 96 are cooperatively configured such that a minimum air velocity exiting the stimulus applicator 40 is approximately 0.4 m/s with an airflow rate of, for example, approximately 3 cc/s or greater. As shown in the embodiment of FIG. 4, the stimulus applicator 40 can include a nozzle 116.

The treatment device 68 may include any suitable components in order to carry out selected skin care treatments including but not limited to chemical, light, ultrasound, heat, magnetic or RF treatment, iontophoresis, phonophoresis, microdermabrasion, among others. In the embodiment shown in FIG. 3, the treatment device 68 administers a chemical spray. In that regard, the treatment unit 52 may include a chemical spray pump and internal fluid reservoir. In this embodiment, the chemical spray pump is connected in fluid communication with the treatment applicator 36, which can include an outlet 98, via feed conduit 100. In the embodiment shown in FIG. 4, the treatment applicator 36 can include a nozzle 118, which in some embodiments can be orientated at a relative angle a to the nozzle 116 of stimulus applicator 40 in order for the spray envelope 124 from the treatment nozzle 118 to be contained by or lie completely within the air flow envelope 128 of the stimulus nozzle 116. In some embodiments, an additional or alternative external fluid source can be coupled in communication with the spray pump.

In use, upon activation of the switch 74, the treatment control 64 operates the fan 86 so that: (1) air exits the outlet 96 at a velocity of 0.4 m/s or greater and for a duration of 80 milliseconds or longer; and (2) the skin care treatment is administered by the device 68 at least 80 milliseconds or longer after the stimulus, e.g., air, is first discharged from the outlet 96. In some embodiments, continued stimulus from the stimulus device 70 can be administered to maintain a closed-eye condition.
