DETAILED DESCRPTION OF THE PREFERRED EMBODIMENTS
[0038] The present invention is best understood by reference to the detailed description and examples set forth herein.
[0039] Embodiments of the invention are discussed below with reference to the examples. However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these examples is for explanatory purposes as the invention extends beyond these limited embodiments. For example, it should be appreciated that those skilled in the art will, in light of the teachings of the present invention, recognize a multiplicity of alternate and suitable approaches, depending upon the needs of the particular application, to implement the functionality of any given detail described herein, beyond the particular implementation choices in the following embodiments described and shown. That is, there are numerous modifications and variations of the invention that are too numerous to be listed but that all fit within the scope of the invention. Also, singular words should be read as plural and vice versa and masculine as feminine and vice versa, where appropriate, and alternative embodiments do not necessarily imply that the two are mutually exclusive.
[0040] It is to be further understood that the present invention is not limited to the particular methodology, compounds, materials, manufacturing techniques, uses, and applications, described herein, as these may vary. It is also to be understood that the terminology used herein is used for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present invention. It must be noted that as used herein and in the appended claims, the singular forms “a,” “an,” and “the” include the plural reference unless the context clearly dictates otherwise. Thus, for example, a reference to “an element” is a reference to one or more elements and includes equivalents thereof known to those skilled in the art. Similarly, for another example, a reference to “a step” or “a means” is a reference to one or more steps or means and may include sub-steps and subservient means. All conjunctions used are to be understood in the most inclusive sense possible. Thus, the word “or” should be understood as having the definition of a logical “or” rather than that of a logical “exclusive or” unless the context clearly necessitates otherwise. Structures described herein are to be understood also to refer to functional equivalents of such structures. Language that may be construed to express approximation should be so understood unless the context clearly dictates otherwise.
[0041] Unless defined otherwise, all technical and scientific terms used herein have the same meanings as commonly understood by one of ordinary skill in the art to which this invention belongs. Preferred methods, techniques, devices, and materials are described, although any methods, techniques, devices, or materials similar or equivalent to those described herein may be used in the practice or testing of the present invention.
[0042] As used herein, the terms “vapor” and “steam” may be used interchangeably, and refers to: (1) water in the gas phase, which is formed when water boils; and (2) wet steam, which is the visible mist or aerosol of water droplets formed as this water vapor condenses; and/or (3) the vapor or gaseous phase of a fluid or medications.
[0043] As used herein, the term “capillary action” (sometimes referred to as also “capillarity” or “capillary motion”) is the ability of a liquid or fluid to flow in narrow spaces or pore without the assistance of, or even in opposition to, external forces like gravity.
[0044] Referring now to
[0045] More specifically, with reference still to

[0048] In exemplary embodiments, the hydrophilic material 126 comprises a plurality of pores and allows the fluid from the first chamber to slowly seep into material, where it travels into the second chamber 118 to be converted into vapor or steam, which then rises through the second chamber 118 and through additional elements, to the eye, eyelid or skin of the user. The hydrophilic material 126, as define herein, is a material which has a strong affinity for water. Even more specifically, the material used herein is defined as hydrophilic by the geometry of water on a flat surface, specifically, the angle between a droplet's edge and the surface underneath it (contact angle). If the droplet spreads, wetting a large area of the surface, then the contact angle is less than 90 degrees and that surface is considered hydrophilic. In exemplary embodiments, the material is absorbent, wicking, cleanable, durable, dimensionally stable, and anti-pathogenic. Exemplary materials comprise cellulose-based materials. The material may be treated to render it hydrophilic, such as with an anionic-ethoxylated sulfonated polyester (AESP) and a high molecular weight ethoxylated polyester (HMWEP) to maximize its hydrophilicity. In optional embodiments, the material may be a fabric such as a polyester/cotton blend, nylon, corn fiber, or other fibers that are conducive to capillary action. The material may be a microdenier knitted fabric, but it may alternatively be an ordinary knitted fabric or a woven tufted or non-woven fabric, or a mesh. In optional embodiments, the material may comprise a metal mesh framework, a synthetic mesh framework, or a cable rope. The material may also be heat-resistant. The material may further be flecked with an antimicrobial agent, such as silver.
[0049] The material 126 may have pores or capillaries for the fluid to travel through via sorption and/or capillary action. In embodiments, it may use capillary action to convey fluid from the first chamber to the hydrophilic material 126 to the second chamber 118 where it is heated by heating element 124 to produce a vapor that rises though the second chamber 118. The heating element 124 may be positioned on a top side of the hydrophilic material 126. In other embodiments, the heating element 124 may surround the hydrophilic material 126 like a shroud. In other embodiments, such as that shown in
[0050] The hydrophilic material 126 may be comprised of a single material throughout, or be comprises of a different material on the bottom portion than the middle or top portions, or the outer portion and the inner portion. In some embodiments, the hydrophilic material 126 may be tubular in shape, cubed, or be a strip. The fabric may also be bundled much like if one were to push a cloth down into a chamber. In an embodiment, hydrophilic material 126 is a tubular shaped member compressed in passage 128, leaving a small space between the bottom of the material 126 and the bottom internal portion of the housing. In this way, the material 126 fits snuggly in the passage 126 so that a seal is formed between edges of the material 126 and the first chamber 116, such that fluid flow will be through the pores through material 126 and not through any edge gaps exceeding the average pore. Consequently, the material 126 should be of appropriate pore size and material so that capillary action provides a supply of fluid 130 such that when heat is transferred from heating member 124 to material 126, the material 126 provides for a boiling transition from liquid to vapor/steam over an appropriate range of temperatures and pressures. Also, a vapor tight seal between due to compression between the material 126 the edges of 134 of the chambers. The space is configured to allow fluid to seep in and form a shallow fluid reserve for the fluid to seep in from the first chamber 116.
