r 7 Claims. (Cl. 128-401) This invention relates to heat producing devices for use within the human body. More particularly, this invention relates to devices for applying heat produced by electrical or chemical means to body cavities where warmth would alleviate pain and otherwise provide comfort and aid in healing infections and other bodily malfunctions.

The use of heat as a therapeutic agent in the treatment of disease conditions of the human body is a time-honored procedure, and its effectiveness in reducing muscular tension and pain, and as a help to the body in overcoming various infiammations and infections, has been established. Although many devices have been constructed.to apply heat to the body, they all suffer from one or more disadvantages which restrict their use.

. Many of these known devices, particularly those electrical types for application of heat to the human pelvis, require the patient to remain immobile when they are being used. This is very undesirable, particularly where the treatment period is prolonged and the patient is otherwise able to go about a normal daily routine. Many of these devices are expensive; some are so highly specialized that a trained technician is required to operate them, so that thepatient must go to the doctors ofiice for each treatment. Some of the heating devices are quite uncomfortable, and thus their use often results in complaints from the patient. Many of these heating devices can be used either only in body cavities or only on the outside .of the body. Cleaning problems, bulkiness, and other esthetic drawbacks are additional disadvantages of many common heating devices.

Treating diseased conditions of the body with antibiotics, creams, and other medicinals can be expensive, particularly when the treatment period is prolonged, as for instance in pelvic, prostatic, .and gum infections. Sometimes, too, the response of the patient to this type of treatment is not asquick or complete as expected. Although heat will.enhance the efiicacy of this type of therapy, until the present invention no means were available to provide the heat in a satisfactory manner.

Accordingly, an important object of our invention is to provide portable heating devices for use in body cavities as well as on the outside of the body, all while the patient remains completely ambulatory.

Another object of our invention istoprovide light-- weight and comfortable heating devices, for use either within or outside of-the body, which can be worn and carried about easily by the patient. 7

- Another object of our invention is to provide less expensive body heating devices that, because they make possible more economical therapy, will be better accepted and utilized, resulting in more eifective therapy. A further object of our invention is to provide body heating devices that are quick and easy to clean and to sterilize. i

Another object of our invention is to provide new body heating devices thatelicit ready acceptance by patients,

especially from the esthetic and psychological viewpoints.

Still another object of our invention is to provide new devices for heating the body in conjunction with, as well as in lieu of, treatment with antibiotics, creams, and

other medicinals.

Further objects and advantages of our invention will become more apparent from the following detailed description thereof taken in conjunction with the accompanying drawings in which:

Broadly considered, our invention involves several forms of body heating devices employing, as the heat producing means, either electrical or chemical energy. These devices have several common characteristics, yet they also necessarily differ in several respects. Each device is completely portable, can be carried about easily by the patient, and is capable of being worn while the patent is ambulatory. Each device produces heat sufficient to increase the temperature at the surface of that portion of the body to which it is applied from the normal body temperature to approximately 120 F. within about minutes, and to maintain that body portion at that elevated temperature for a prolonged period of time.

These devices can be made in any appropriate size, shape and configuration to suit the particular use for which they are intended. For example, they can be rodlike, disc or wafer-like, etc., and can be flat or contoured, round or rectangular, long or short, slender or fat, and straight or curved. They also can be perforated to avoid trapping of secretions or discharges. All the devices are constructed from innocuous materials, including plastic, rubber, or rubber-like compositions, and all are safe for use under conditions where moisture is present without danger of shock, or electrical or chemical burn.

The electrical device As illustrated in FIGS. 1, 2, and 3, one form 30 of electrical heating device of our invention comprises a round, wafer-like diaphragm 31 with a relatively thin central membrane 32 surrounded by a peripheral annular rim 33 and a metallic electrical resistance heating element 34 encased within the member 32. In effect, the membrane 32 forms a housing for holding the heating element 34 in a fixed, generally planar position, and in a predetermined pattern extending across the membrane. A suitable length of small gauge insulated electrical conductor 35 connects the heating element 34 to a small, portable battery 36 through a plug 37 and an elf-on switch 38. For convenience in carrying, the battery 36 can be placed in a suitable case 39, and placed in a pocket or clipped to an article of clothing by a clip 49.

The pliability of the rim 33 may vary from stilt to flexible, as long as it has sufiicient strength to retain the diaphragm 31 in place: for some applications the rim may be omitted altogether. As a help in maintaining the diaphragm 31 in proper position, a helical or fiat metallic, plastic, rubber, or rubber-like spring 41 (FIG. 3) can be enclosed within the annular rim 33 preferably completely sealed oft from the outside so that no body fluids contact it.

In addition to the round form illustrated in FIGS. 1-3, the diaphragm 31 can be of other shapes and configurations, and can be made in any size, depending on its intended use. Although the illustrated membrane 32 is of one layer, a two-layered membrane with the heating element 34, and perhaps a few drops of heat dispersing liquid, between the layers can also be used if desired.

The membrane 32 and the rim 33 can be constructed from plastic, rubber or rubber-like material, all of which are non-conductors of electricity yet transfer heat. The rim 33 also can be made of metal, and then enclosed within any or" these plastic, rubber or rubber-like materials. The insulated electrical conductor 35 connecting the battery 36 to the heating element 34 can be covered with a soft fluffy material (not shown) to prevent irritation to the patient; this material is designed to stay on when the diaphragm 31 and conductor 35 are cleansed.

Various types of batteries producing a potential of between about 1.5 to 6 volts are suitable to power the heating element 34; for example, a battery that can be recharged by connecting it to a conventional volt alternating current outlet can be used, and conventional dry flashlight type batteries connected together to provide the desired voltage are also operable. In cases where mobility of the patient is not a primary consideration, a larger battery with a longer life-span will provide the proper voltage and energy to yield a comparable desired temperature rise.

The heating element 34 preferably is a wire of Nichrome, Chromel, or other suitable electrically resistant material, of a size appropriate to produce the desired amount of heat. The configuration, length, and diameter of this Wire can be varied to suit particular needs, and thus the element 34 in FIGS. 1 and 3, and the corresponding elements in the other figures, are merely illustrative and not intended to be limiting.

The diaphragm 31, the conductor 35, and the plug 37 are immersible in water, and by simply unplugging the battery 36 they all can be cleansed, as with soap and water, for further use. If desired, they can also be sterilized by autoclaving, cold chemicals, and other conventional sterilizing methods well known in the medical art.

Another form of electrical heating device of this invention is illustrated in FIGS. 4, 5 and 6. This device 45 is designed for treating abcessed teeth and gum infections, and has somewhat of an I-beam cross-sectional configuration with lateral flanges 42 and 43 joined by a medial web 44. The heating element 46 courses in a continuous path through the flanges and exits as an insulated conductor 47 which is connected to a battery, etc. (not shown), in the same manner as in the diaphragm device 31 of FIGS. 1, 2 and 3.

The anterior end 48 of the gum device 45 is shaped to fit over the incisor teeth, and the posterior end 49 is shaped to fit over the molars, with the area in between shaped to fit the intermediate teeth.

In the same manner as the diaphragm device 31, the device 45 is constructed from plastic, rubber, or rubberlike material, is washable, and can be sterilized. The configuration, length, and diameter of the heating element can be varied to suit any need, as can be the composition thereof, so that the element 46 is merely illustrative and not intended to be limiting.

FIGURES 7, 8 and 9 illustrate yet another form of electrical heating device of our invention. This device 50 comprises a relatively long, narrow, and flat body 51 through which a heating element 52 courses, exiting at one end of the body 51 as an insulated conductor 53 which is connected to a battery, etc. (not shown), as are the conductors 35 and 47 of the devices 31 and 45. This device 50 is designed primarily for intra-rectal use, although it can be used within other body cavities, or upon other parts of the body if desired. The body 51 also is constructed of plastic, rubber, or rubber-like material that is washable and sterilizable, and the configuration, length, and diameter of the heating element 52 can be as illustrated or otherwise, and its composition can be varied, all just as with the elements 34 and 46.

The electrical heating device 60 of FIGURES l0 and 11 is especially suitable for intra-urethral use in women. It is comprised of a relatively long, slender, cylindrical body 61, also of plastic, rubber, or rubber-like composition, containing a heating element 62 with a convoluted or other desirable configuration and of a suitable length and diameter, as with the previous described electrical devices, the heating element 62 emerges from the body 61 as an insulated conductor 63 which is connected to a suitable battery (not shown). This intra-urethral device is washable and sterilizable as are the other electrical devices, and thus can be used repeatedly.

The chemical devices The heating devices of our invention that make use of a chemical reaction to supply the heat all operate in the same general manner. Broadly speaking, these devices comprise two chemical agents encapsulated separately within a plastic, rubber, or rubber-like container that is shaped to fit the particular part of he body to which it is The chemical agents utilized in the heating process are arranged within the container so that, as the exothermic reaction progresses, the heat produced is maintained throughout the entire heating cycle and is evenly distributed across the entire container surface.

One form of chemical heating device of this invention is illustrated in FIGS. 12 and 13. This device 70 is very similar to the electrical device in that it too comprises a round, wafer-like diaphragm 71, constructed from the same type of material and having the same properties as the diaphragm 31, with a relatively thin membrane 72 surrounded by a peripheral rim 73 enclosing a flat (or helical) spring 74.

However, here the similarity ends, for instead of a wire heating element, etc., the device 70 is fitted with a disposable wafer 75 containing the exothermically reacting chemicals 76 and 77 in two distinct compartments 78 and 79 divided by a removable, separable or frangible barrier 80. The disposable wafer 75 fits snugly into the reusable diaphragm 71 with its periphery 75a extending into the V-shaped joint formed at the intersection of the membrane 72 with the rim 73 of the diaphragm 71, yet can be inserted and removed easily by the fingers. As is evident, this diaphragm 71 may be prepared for reuse simply by cleansing, sterilizing, and inserting a new wafer 75. A length of cord 81 can be attached to the device 70 to facilitate its removal from the body cavity.

A completely disposable modification of this chemical heating device 70 is illustrated in FIGURES 14 and 15. Here, instead of an individual diaphragm and a chemicalcontaining wafer, all features are combined into one complete unit 82, with a membrane of two layers 83 and 84, both of which are joined along their common periphery to a rim 85. A removable, separable or frangible barrier 86 between the two membrane layers 83 and 84 divides the space between these layers into two distinct compartments 87 and 88 which house the exothermic reacting chemicals (not shown). Although the device 82 is illustrated without a spring in the rim 85, it can be constructed with a spring if desired, just as the devices 30 and 70. As with the device 70, a length of cord 89 attached to the device 82 helps in removing it from a cavity in the body.

As with the diaphragms 31 and 71, the device 82 is constructed from a plastic, rubber, or rubber-like material that is suitably flexible to fit the body part for which it was designed, and is physically and chemically suitable to assure containment of the heat producing agents.

In the same manner that the shape and size of the reusable devices can be varied, the completely disposable type of chemical heating device can be made in other shapes, and in any size, to suit the particular application. For example, as illustrated in FIGS. 16, 17 and 18, it can be relatively long, fiat, and slender for intra-rectal use and, as illustrated in FIGS. 19 and 20, it can be tubular-shaped and curved, for intra-urethra-l use in women. Both the rectal device 91 and the urethral device 101 have two compartments 92, 93, and 102, 103, respectively, and a removable, separable or frangible barrier 94 and 104, respectively, for the chemicals, and are constructed from the same type of plastic, rubber, or rubber-like material as are the other devices. Also, both devices 91 and 101 preferably have lengths of cord 95 and 105, respectively, to provide an easy be placed.

A somewhat different form of our chemical heating device which, although perhaps slightly uncomfortable, can be used by ambulatory patients is illustrated in FIGS. 21 and 22. This device is designed for rectal or vaginal use, and comprises a relatively short tubular body 111 with an oval or an egg-shaped end 112 integral with the body side wall 113, and a rod-like insertion handle 114 that can be threaded into the open end 115 of thebody 111. An ampoule 116, containing the exothermically-reacting chemicals, fits within the hollow core 117 of the body 111 to provide the required heat. I The body 111, as well as the handle 114, also can be constructed from-plastic, rubber, or rubber-like material as used in the other forms of our heating devices, but the handle 1 14 should be rigid enough to adequately serve to insert the body 111 into position. As in the other heating devices, varying amounts of aluminum, copper, iron or other heat-retaining and heat-distributing metal in powdered or crystalline form may be mixed with the plastic, etc. before the body and handle are formed.

This chemical heating device 110 also is immersible in water, and can be cleansed, as with soap and water, and sterilized for further use.

The devices of this invention will produce the proper amount of heat that has been found helpful in treating infections such as boils, pelvic inflammatory diseases in women, bladder, urethral, and prostate infections, ulcer of the bladder especially in women, and various other infections where the application of heat is beneficial. In fact, the use of these devices gives symptomatic comfort and relief wherever heat application provides these results. These devices are comfortable, and they do not require specialized assistance and expensive equipment for their use. The ideal treatment period with our devices is relatively short, from 15 to 60 minutes, and may be repeated several times a day where needed, all without having to wait in or return to the doctors oflice.

To those skilled in the art to which this invention relates, many changes in construction and widely differing embodiments and applications of the invention will suggest themselves without departing from the spirit and scope of the invention. The disclosures and the descriptions herein are purely illustrative and are not intended to be in any sense limiting.
