Patent Application

This invention generally relates to a photo therapy apparatus, and more specifically to a photo therapy apparatus for improving experience of breastfeeding.
Pain accruing from nipple lesions caused by inadequate latching by the baby is a common complaint among breastfeeding women and an important obstacle to successful breastfeeding. Low-level laser therapy was considered effective for treating nipple lesions in breastfeeding women with pain, providing relief and prolonging exclusive breastfeeding. It is the thus goal of the present invention to provide a convenient photo therapy apparatus for improving experience of breastfeeding. The photo therapy apparatus comprises one or more light sources that are integrated with a breast pump for reduction of sore and inflammation, treatment of damaged nipples, blocked ducts, and mastitis, which in turn bring in the advantage of more milk production, more milk yielded per session, and more comfort with reduced pump pressure.
The photo therapy apparatus of the present invention comprises one or more light sources which are integrated with a breast pump for providing photo therapy treatment to the breast and nipple of women during pumping of breast milk. The light sources can be lasers, light emitting diodes (LEDs), lamps, or any other types of light sources which produce therapeutic light in a desired wavelength range. The therapeutic light is delivered through the breast-shield or flange of the breast pump to the breast and nipple and produces a variety of photochemical processes, e.g. increase of ATP (adenosine triphosphate), triggering of photo neurological response and activation of enzymes, changes in local pressure, increases in temperature, and deformation of cellular membranes. Such photochemical reaction helps to reduce pain and promote healing of nipple lesion and in the meantime enhance yield of breast milk.
The accompanying figures, where like reference numerals refer to identical or functionally similar elements throughout the separate views and which together with the detailed description below are incorporated in and form part of the specification, serve to further illustrate various embodiments and to explain various principles and advantages all in accordance with the present invention.
Skilled artisans will appreciate that elements in the figures are illustrated for simplicity and clarity and have not necessarily been drawn to scale. For example, the dimensions of some of the elements in the figures may be exaggerated relative to other elements to help to improve understanding of embodiments of the present invention.
Before describing in detail embodiments that are in accordance with the present invention, it should be observed that the embodiments reside primarily in combinations of method steps and apparatus components related to a photo therapy apparatus for improving experience of breastfeeding. Accordingly, the apparatus components and method steps have been represented where appropriate by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the present invention so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein.
In this document, relational terms such as first and second, top and bottom, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. The terms “comprises,” “comprising,” or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by “comprises . . . a” does not, without more constraints, preclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.
A first exemplary embodiment of the photo therapy apparatus is shown in
Depending on the output wavelength of the light source 108, the therapeutic light can provide a variety of treatment effects. The ultraviolet (UV)-blue light, at a wavelength of 370 to 490 nm, has high photon energy, which can help to produce singlet oxygen and effectively destroy bacteria. The red light, at a wavelength of 620 to 700 nm, can penetrate human tissue to a depth of about 8-10 mm. Skin layers, because of their high blood and water content, easily absorb red light, which helps to increase blood circulation and decrease inflammation/irritation. The near-infrared (NIR) light, at a wavelength of >700 nm, has been demonstrated to be beneficial for increasing cytochrome oxidase activity and ATP (adenosine triphosphate) content as well as promoting wound healing and relieving pain. In addition, the near-infrared light penetrates to a depth of about 30-40 mm, which makes it more effective for deep muscles. The light source 108 may comprise multiple light sources with different output wavelengths, each wavelength matching with the absorption band of a specific chromophore (water, hemoglobin, lipid, protein, etc.) of the subject breast tissue.
In a slight variation of the present embodiment, an optical component (not shown) is inserted between the light source 108 and the breast-shield or flange 102 for controlling the intensity distribution of the therapeutic light. Such optical component can be a holographic diffuser or a micro-lens array which has a large number of microstructures on its surface. As one example, the holographic diffuser or the micro-lens array may produce an unevenly distributed light intensity. This intensity modulation will help to further improve the therapeutic effect of the light source 108. In yet another variation of the present embodiment, the light source 108 may be embedded inside the breast-shield or flange 102 of a breast pump 100 to produce therapeutic light thereof.
In the foregoing specification, specific embodiments of the present invention have been described. However, one of ordinary skill in the art appreciates that various modifications and changes can be made without departing from the scope of the present invention as set forth in the claims below. Accordingly, the specification and figures are to be regarded in an illustrative rather than a restrictive sense, and all such modifications are intended to be included within the scope of present invention. The benefits, advantages, solutions to problems, and any element(s) that may cause any benefit, advantage, or solution to occur or become more pronounced are not to be construed as a critical, required, or essential features or elements of any or all the claims. The invention is defined solely by the appended claims including any amendments made during the pendency of this application and all equivalents of those claims as issued.
This application claims inventions which were disclosed in Provisional Patent Application No. 62/482,862, filed Apr. 7, 2017, entitled “APPARATUS FOR IMPROVING EXPERIENCE OF BREASTFEEDING”. The benefit under 35 USC § 119(e) of the above mentioned United States Provisional Application is hereby claimed, and the aforementioned application is hereby incorporated herein by reference.
