CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority to U.S. provisional patent application serial number 60/366,551, filed March 25, 2002. The provisional application serial number 60/366,551 is incorporated by reference herein.
FIELD OF THE INVENTION
[0002] The present invention provides for a method and apparatus for the application of specific wavelengths of light to skin tissue for the purpose of treating and healing acne lesions BACKGROUND OF THE INVENTION
[0003] Roughly 45 million people in the US are afflicted by the skin condition acne vulgaris. It is associated with lesions on the skin that are unsightly but can also be painful and leave scars.
[0004] The exact etiology of acne remains controversial. Keratinous material initially plugs the duct of a sebaceous gland. Sebum is produced and trapped, thereby enlarging the gland. The propionibacterium aches (P. aches) bacterium, which is a normal part of the skin flora, propagates in the gland due to the sebum buildup. These bacteria are inflammatory and may lead to the formation of the acne pustules.
[0005] Treatments typically include topical and systemic therapies. Topical treatments are aimed at removing follicular plugs and cleaning the sebaceous glands. These treatments are useful in treating some minor forms of acne. Oral treatments include antibiotics to suppress the growth of P. aches. However, these treatments have side effects typical of these drugs, such as skin dryness, digestive problems, and the development of antibiotic resistant bacteria.
[0006] It is known that the P. aches bacteria produce porphyrins. The particular porphyrin typically produced by P. aches has a peak in absorption at 415 nanometers.
Although red light is absorbed less, the light penetrates the skin deeper than other light. Thus, devices often include 660 nanometer light as well. Also, red light has an anti-inflammatory effect on tissue and may therefore aid in improving healing of pustules.
Although red light is absorbed less, the light penetrates the skin deeper than other light. Thus, devices often include 660 nanometer light as well. Also, red light has an anti-inflammatory effect on tissue and may therefore aid in improving healing of pustules.
[0007] More recently, the use of both blue light (e.g., 415 nm) and red light (e.g., 660 nm) in the treatment of acne has been described. These lights can be applied with and without photo enhancers. These devices typically require high energy light sources to limit the treatment time to a period that is acceptable for a person to sit still. For example, the light sources tend to be high energy fluorescent bulbs and LEDs.
SUMMARY OF THE INVENTION
SUMMARY OF THE INVENTION
[0008] The present invention provides the ability to treat acne with a device that can be worn by a patient for extended time periods. The device can, for example, enable the delivery of light for time periods that are longer than one might want to sit still in front of a stationary light source. The device is a flexible container that may be fitted to parts of the body to be treated.
An example of such a flexible container is a mask for the face. The mask covers the face and has a strap to hold it to the face. The mask is located relative to a light source generating light by chemiluminescence. The mask is worn for a period of time needed to provide the desired amount of light energy to the tissue.
An example of such a flexible container is a mask for the face. The mask covers the face and has a strap to hold it to the face. The mask is located relative to a light source generating light by chemiluminescence. The mask is worn for a period of time needed to provide the desired amount of light energy to the tissue.
[0009] Chemiluminescence is a chemical reaction that emits light. In practice, two chemicals in liquid form are mixed together. In one embodiment, the mask contains a first portion storing a first chemical and a second portion storing a second chemical. The chemicals mix when, for example, the user breaks a breakable barrier (i.e., a separating mechanism) separating the two portions. The resulting chemical reaction emits light of specific wavelengths) and for certain amounts of time. The chemicals contain both a dyes) that creates the specific wavelengths) of light and an energy-releasing reaction species providing the energy required to "pump" the dye molecules to a higher energy state. When the dye molecule naturally relaxes from its higher energy state, a photon of a specific wavelength is released. The proper selection of the chemicals can provide light of a specific wavelength peak, or, by combining multiple chemicals with different dyes, light of multiple peaks can be delivered. In addition, the chemicals providing the energy-supplying reaction can be selected to be a rapid, very energetic reaction or a longer, slower and less energetic reaction. If one desires a low light intensity for a long time, the chemicals are selected for a slow reaction rate. Conversely, for high intensity, the chemicals for a fast reaction are used. The total number of photons delivered depends on the energy produced by the reaction, the efficiency of the reaction in exciting the dye to its higher energy state, and the efficiency in the excited dye molecules returning to their lower energy state.
The brightness of the illumination and the duration of the light are dependent on first order chemical reaction kinetics. That is, heating up the chemicals makes the reaction rate faster, approximately twice as fast for a 10 degree centigrade increase in temperature.
The brightness of the illumination and the duration of the light are dependent on first order chemical reaction kinetics. That is, heating up the chemicals makes the reaction rate faster, approximately twice as fast for a 10 degree centigrade increase in temperature.
[0010) In one embodiment, the light source generates light having a wavelength between about 400 nm and about 450 nm. The light source can also generate additional light having a S wavelength between about 630 nm and about 690 nm. In yet another embodiment, the light source generates additional light having a wavelength between about 525 nm and 575 nm.
[0011] The masks are made to fit various parts of the body that are affected by acne including the face and/or the back. In one embodiment, the mask is made from a flexible material. For the face, eye, nose and mouth holes are provided. The distal part of each mask is opaque to ensure that most of the light is directed to the tissue.
BRIEF DESCRIPTION OF THE DRAWINGS
BRIEF DESCRIPTION OF THE DRAWINGS
[0012] FIG. 1 is a schematic representation of an embodiment of an illuminating face mask.
[0013] FIG. 2 illustrates an embodiment of a section of the face mask construction.
[0014) FIG. 3 illustrates an embodiment of a face mask on a person.
[0015) FIG. 4 illustrates an embodiment of a body mask on a person.
DETAILED DESCRIPTION OF THE DRAWINGS
DETAILED DESCRIPTION OF THE DRAWINGS
[0016] FIG. 1 illustrates a schematic representation of a mask 1. The mask 1 can have holes for the eyes 3, nose 5 and mouth 4. Alternatively, the mask 1 may have any combination of the holes for the eyes 3, nose 5, and mouth 4 (e.g., holes for the eyes 3 and mouth 4). There is also a strap 6 for holding the mask in place around the head. In one embodiment, the mask 1 includes a fill port 9 that is closed (e.g., by welding or gluing) once the mask is filled. Also referring to FIG. 2, the construction of the mask 1 is such that there is a front sheet 8 and a back sheet 7. The two sheets 7, 8 are joined along their periphery 2 to provide a seal. The sheets may be, for example, welded or glued. Materials may include nylon 6-6, PVC, PET or other translucent polymers. The front sheet 8 can be opaque to light or reflective to reflect the light back towards the back sheet 7 towards the skin to trap the most amount of useful light and direct it to the desired treatment area. The front sheet 8 can be made from opaque or reflective (silver coated) plastics.
(0017] Referring to FIG. 3, the face mask 11 is shown in place on the head 12 using the head strap 13. FIG. 4 shows a body mask ~14 in place on the upper torso 15.
The body mask 14 may cover the front and/or back of the user.
The body mask 14 may cover the front and/or back of the user.
[0018) Refernng again to FIG. 1, the mask 1 in FIG. 1 is filled with the chemiluminescent solutions through fill ports 9 and 17. The ports 9, 17 are then sealed by, for example, gluing or welding shut. The two solutions are separated in the mask 1 by welding the materials 7 and 8 together along the midline 10 of the mask. In use, the user squeezes the mask, breaking the weld 10 and permitting the solutions to mix.
[0019] Alternatively, the mask 1 may be filled with one of the necessary components. A
thin glass ampule or plastic package filled with the other solution may be inserted into the mask.
The user then breaks the glass ampule or plastic package by squeezing. This releases the activator which mixes with the dye and activates the light source.

The user then breaks the glass ampule or plastic package by squeezing. This releases the activator which mixes with the dye and activates the light source.
[0020] The activity of the chemicals is selected to provide blue light with a peak around 415 nm~, as this is the wavelength of the peak kill rate of the P. aches. In other embodiments, the light has a wavelength within a range of 400-450 nm. There is also a peak in the porphyrin absorption around SSOnm so that additionally, we may want to provide chemicals with outputs of 525-575nm. In some embodiments, chemicals that provide red light around 660 nm (630-690nm) are applied to reduce inflammation of the tissue. Any or all of these dyes might be included in each device.
[0021] The effectiveness of killing P. aches is dependent on the total amount of energy delivered. In one embodiment, the total amount of energy exposure is between 320 and 430 J/cm2. Further, the energy delivered in these treatments can, for example, range from 4 to 90 mW/cm2. In other embodiments, longer treatments with lower energy exposures is more effective at killing the P. aches bacteria. The benefit of this invention is that the user may wear the device and continue with daily chores or routines permitting the exposure of large amounts of energy per treatment at low powers or fluxes. Currently available light treatments require the user to sit or lie in front of a light source and therefore interrupts daily activity.
[0022] In addition to the light delivery, the mask can also deliver skin softeners or cleansers. The front sheet 7 is impregnated with skin cleansing solutions that transfers to the skin during the treatment.
[0023) In yet other embodiments, the mask 1 can be reused a predetermined number of times prior to disposal to, for instance, lower user costs. For example, the mask 1 may contain several compartments of activators, one of which is opened at a time. Another example is that the mask 1 has several glass ampules with activators inside the mask, and one glass ampule is broken at a time. The chemical reaction then proceeds until the activator is used up, but unreacted dye remains to react with the next activator that is exposed when the next glass ampule is broken.
(0024] The mask may also have a port through which the solutions can be introduced.
Syringes are filled with each of the two solutions, dye and activator. Each component is then injected into the mask and mixed inside the mask. The port has a valve to keep the fluids inside during use. The valve is opened to drain the fluids after use prior to the next use.

[0025] Having described certain embodiments of the invention, it will now become apparent to one of skill in the art that other embodiments incorporating the concepts of the invention may be used. Therefore, the invention should not be limited to certain embodiments, but rather should be limited only by the spirit and scope of the following claims.
