Definitions

  • agent B receives heat from source A and delivers its heat to load object C.
  • agent B receives cold (gives up its heat to) source A and gives up its cold (receives heat from) load object C.
  • agent B receives cold (gives up its heat to) source A and gives up its cold (receives heat from) load object C.
  • load object of cold a source of heat
  • source of cold the load object of heat.
  • intermediate agents play a similar role in heating and cooling.
  • Topical applications of heat or cold to the body are well known methods of therapeutic treatment for specific conditions.
  • Cold application is usually recommended to reduce swelling and pain associated with minor injuries, sprains, bumps and bruises, as well as minor burns.
  • Heat application is usually beneficial for relief of muscular or skeletal aches, cramps and joint stiffness related to arthritic conditions. Heat treatment also promotes healing and reduces stress and tenseness.
  • Optional forms of heat treatment may be called for and provided with or without accompanying moisture.
  • thermo treatments are commonly referred to as compresses, heating/cooling pads or, generically, as therming packs.
  • Products of this type usually consist of several basic elements, as follows: 1. A therming agent or therming medium as working payload; a mass of material, liquid or particulate solid, which serves as a source of heat, when preheated, or cold, when pre-chilled.
  • More conventional heating pads are well known. They serve as sources of dry heat, with added moisture as an option. The latter is usually provided externally by wetting the outer fabric cover of the pad.
  • Home-based products such as ice bags and hot water bottles deliver cold and dry heat. Here too, moisture can be added externally as an option via moistened towels and the like.
  • Some pads intended exclusively for moist heat application are constructed of absorbent fabric or foam materials. They are simply immersed in hot water or moistened and microwaved before use.
  • Another group of products is referred to as gel packs. Their working payload consists of aqueous gel compositions, which are permanently sealed in plastic bags. They provide cold after storage in a freezer. They also provide heat after immersion in a hot water bath or microwaving.
  • the broad range of such particulates currently in use includes natural grains such as rice, as well as, silica gel and activated alumina.
  • the source of transmittable moisture is either innate, as in grains, or absorbed by the particulate solid. Some of these particulates are capable of replenishing lost moisture by reabsorbing it from ambient air. Thus, the prospective user of the pad is assured a source of moisture without the need to supply it initially or replenish it subsequently from outside sources.
  • One such particulate agent is described in U.S. Patent No. 5,314,005, which was granted to this applicant on May 24, 1994.
  • Some heating pads containing particulate therming media are also claimed to be suitable for cold applications.
  • cold treatment with such pads is not an effective or practicable option for two major reasons.
  • the first reason relates to the payload's limited capacity to store cold. Because the water contained in the particles is not free to undergo a change of phase upon cooling, the payload is only able to store sensible cold. In other words, it cannot benefit from the latent heat of freezing which, for water, is rather substantial.
  • the second reason relates to the fabrics in which the particles are contained. These fabrics are usually selected to be not only vapor permeable, for the sake of transmitting vaporized water, but also somewhat thermally insulating.
  • the object of this invention is to provide novel means of containment for particulate heating/cooling agents to enhance their performance.
  • Another object of the invention is to provide a therming pack which is at least tri-functional, capable of delivering cold, dry heat and moist heat, the latter without the addition of water from external sources.
  • a further object of the invention is to make the thermal treatments, which the pack provides effective, directional, energy efficient and safe.
  • moisture bearing therming media are retained in cloth pads which have two distinctly different working surfaces, one moisture impervious and the other moisture permeable.
  • the moisture impervious surface of the pad is made of a thin, thermally conductive coated fabric.
  • the moisture permeable surface of the pad is made of a thicker and somewhat thermally insulating fabric. The latter also extends beyond the edge of the pad to form a flap large enough to cover either surface of the pad as needed.
  • the pad is either pre-chilled in a freezer or microwaved before use. With the pad pre-chilled, cold is derived from the pad through the moisture impervious surface.
  • FIG. 1 is a top view of the preferred, multi-functional therming compress of this invention.
  • FIG. 2 is a cross-sectional view of the compress along line AA.
  • FIG. 3 is a cross-sectional view of the compress along line AA, with the flap doubled over the moisture permeable surface of the pad.
  • FIG. 4 is a cross-sectional view of the compress along line AA, with the flap extended and covering the moisture impervious surface of the pad.
  • Multi-functionality in this context, means ability to deliver cold or heat, with the latter being, optionally, dry or moist.
  • Multi-functionality in the broadest sense, also means self-containment or self-sufficiency; ability to perform all of those functions automatically and specifically without the addition of water by the user. It would be advantageous at this point to consider what properties are required of the particulate therming medium in order to perform the desired functions. First and foremost, it should contain a certain proportion of water and thus be a source of moisture for moist heat applications.
  • the delivery of moisture also be reversible; i.e., self-replenished from ambient sources.
  • it should have the capacity to generate and store heat internally for delivery as needed; i.e., be microwave responsive.
  • particulate therming media those already in use, might be suitable for this invention.
  • they include the natural grains, which contain water innately, and drying agents, such as silica gel and activated alumina, which contain adsorbed water.
  • Spherical beads of activated alumina serve as liquid absorbents for the particulate heating/cooling agents described in U.S. Patent No. 5,314,005 which are preferred for this invention.
  • the beads contain a mixture of glycerol and water.
  • the glycerol contributes to the specific heat of the particles which is all-important for the storage of heat or cold. Being a humectant and hydrophile, glycerol also promotes the re- absorption of lost moisture from ambient air.
  • the glycerol is relatively non-volatile and therefore the "permanent" component of the mixture, while the water is volatile and variable.
  • the glycerol remains behind.
  • the glycerol reabsorbs moisture from ambient air as it strives to reach equilibrium with surrounding humidity.
  • the compress is prepared for the next use with its moisture content restored.
  • the particulate therming media are retained in a specially designed therming pad.
  • the pad is assembled from two dissimilar fabrics, one vapor impervious and the other vapor permeable.
  • the fabrics are sewn together to form two distinct working surfaces: one, for our purposes, moisture impervious and the other moisture permeable.
  • the fabrics and corresponding surfaces are colored for easy identification.
  • the moisture impervious surface has different color, for example blue, than the moisture permeable surface, for example white.
  • the moisture permeable (white) fabric extends beyond the edge of the pad. It forms a flap sized to cover one surface of the pad or the other, as desired, for a particular therming application. This will be covered in greater detail when describing how the compress is to be used.
  • FIG. 1 shows a top view of pad 101 with flap 102 fully extended. Also shown are four stitch lines 103 through the surface of the pad. These form five elongated pockets, which retain the particles in place and permit the pad to be bent more easily along the stitch lines.
  • FIG. 2 is a cross-sectional view of the compress through line AA. It shows the particulate payload 106 retained between vapor impermeable fabric 105, forming the moisture impervious surface of the pad, and vapor permeable fabric 104, forming the moisture permeable surface of the pad. Fabric 104 also extends to form flap 102.
  • FIG. 3 shows flap 102 doubled over and covering surface 104.
  • FIG. 4 shows flap 102 extended around the pad and covering surface 105.
  • the moisture permeable fabric of the pad is, typically, a web of nonwoven polyester.
  • the moisture impervious fabric of the pad consists of a woven nylon fabric coated with a thin layer of urethane polymer.
  • the pad is assembled with the urethane coating inside and the nylon fabric outside. Matching pieces of the die-cut fabrics are sewn together, filled with the working payload, and finished off with bindings around the edge of the sewn pad and flap.
  • the compress is used as follows:
  • the compress For cold treatment, the compress is maintained in a freezer, or pre-chilled therein for at least eight hours. When cold treatment is needed, the compress is removed from the freezer and the moisture impervious (blue) surface is applied directly to the skin with moderate compression. The flap, covering the other surface of the compress, conserves whatever cold is stored therein.
  • the compress is microwaved until it reaches an effective working temperature.
  • a compress stored at room temperature obviously requires less microwave time than one removed from the freezer prior to its use.
  • the heated compress provides dry heat through its moisture impervious (blue) surface. If the compress is too hot for direct contact, it may be shielded by the flap initially and then used directly as it cools off. The other surface of the compress may be covered by the user with a towel to conserve heat.
  • the compress is microwaved to its working temperature, with the flap covering the moisture impervious (blue) surface of the compress.
  • the flap shields that surface for safe handling by the user and conserves the heat stored in the compress.
  • Moist heat is applied from the moisture permeable surface of the pad directly onto the skin or, initially, when hot, through a towel. The towel may be removed later as the compress cools down. Lost moisture is drawn back from ambient air into the pad when the latter is not in use.
  • the vapor impervious (blue) surface of the pad serves a number of important functions. Firstly, it bars passage of moisture when the latter is not needed; i.e., for dry heat or cold application. Secondly, it sends moisture in the opposite direction, i.e., toward the moisture permeable (white) surface of the pad, where and when moist heat is desired. Thirdly, its thin gauge and superior thermal conductivity, superior to the other surface of the pad, promotes better heat transfer of cold as well as dry heat.
  • the flap serves a couple of important functions in the performance of the pad. It shields the user from elevated surface temperatures of the pad when that is needed. It also provides thermal insulation, in other cases, to conserve heat or cold and make them last longer.
  • Cooling provided by the compress of this invention is more moderate and longer lasting because cold transfer occurs between particles of the payload. This slows down the rate of cooling by the pad even upon direct contact with the skin. Cooling is thus maintained and sustained at a moderate rate which is numbing but not painful. As an added, unexpected and welcome benefit, it reduces the incidence of surface condensation, obviating the discomfort and nuisance encountered and cited by the prior art.
  • the compress of this invention exhibits true multi-functionality with directional performance enhanced by thermal efficiency, convenience and safety. It does all that with some unexpected benefits as well.
  • the foregoing description is for the purpose of teaching the person of ordinary skill in the art how to practice the present invention. It is not intended to detail all of those obvious variations and alternatives in choice of structural fabrics and related materials, which will become apparent to the skilled practitioner upon reading the description. It is intended, however, that all such variations and alternatives be included within the scope of the present invention which is defined by the following claims:

Abstract

Selon l'invention, des billes d'alumines activées contenant un mélange de glycérol et d'eau absorbé dans ces dernières sont enfermées dans un tampon en tissu qui présente deux surfaces possédant des fonctions différentes, l'une étant perméable et l'autre imperméable à l'humidité. Lorsque le tampon est préchauffé au moyen d'énergie micro-onde, sa surface perméable à l'humidité fournit de la chaleur humide et sa surface imperméable à l'humidité fournit de la chaleur sèche. Lorsque le tampon est prérefrigéré dans un congélateur, sa surface imperméable transmet du froid. L'humidité perdue dans les applications de chaleur humide est reconstituée automatiquement par le glycérol, à partir de l'air ambiant, lorsque le tampon n'est pas utilisé.
