13 Claims. 1
This invention relates to the hydrotherapy art and has as its general object to improve and simplify the treatment of ailments of the human body by the application thereto of moist heat. The commonly accepted method in general use today is to apply, to the body of a patient, usually in a reclining position on a cot or hospital bed, towels that have been saturated in hot water and partially wrung out. Thi practice requires the frequent changing of the towels as the heat of the residual moisture therein is dissipated.
An object of the invention is to provide an improved method of therapeutically treating the human body, wherein heated vapors are applied to the body of a patient lying directly upon a pad which serves as a distributing outlet for the vapors. The invention contemplates particularly the application of heated water vapor or steam, either plain or medicated.
A particular object of the present invention is to provide a method and apparatus whereby moist heat can be continuously applied to a body at a uniform rate. More specifically, the invention contemplates the continuous application of heated Water vapor or steam to the body of a patient at a rate that is regulated to maintain a selected treatment temperature throughout the period of treatment. To this end, the invention contemplates the use of apparatus including a steam generator having means to regulate the delivery of heated vapor therefrom, a vapor delivery pad adapted to distribute the hot Water vapors coming from the generator to a selected area of the patients body while the patient is lying directly upon the pad, and a connection between the generator and the pad for carrying the hot vapors from the generator to the pad.
A specific object of the invention is to provide a delivery pad so constructed as to be capable of supporting the body of the patient While freely delivering the heated vapors thereto. Another object is to provide a delivery pad that Will distribute the vapors quite evenly throughout its area. A further object is to provide a pad that is relatively simple and inexpensive, yet rugged and durable in construction. A further object is to provide a pad which, together with the foregoing characteristics, is flexible and adapted to conform itself to the curvature of the patients body and to the contours of a ielding supporting mattress, as deformed by the body of the patient pressing downwardly thereagainst.
A further object is to provide a pad including an inlet, a plenum chamber for distributing vapors from the inlet, and a plurality of elongated distributing ducts extending from the plenum chamber, each having a series of progressively arranged vapor outlets in its side walls, the ducts and outlets being so constructed and arranged as to distribute the vapor uniformly throughout their length, and being arranged to collectively provide a support for a patients body, adapted to support the body without having its vapor distributing function impaired. Furthermore, the invention contemplates a pad which, though adapted to flex in order to conform to body curvature, will not lose any of its uniform distributing efficiency as the result of such flexing.
A further object of the invention in one of its aspects is to provide a distributing pad having the characteristics set forth above and, in addition, being preformed in a spirally rolled shape such as to receive a limb and having means for adjustably securing the same around limbs of varying diameters.
A further object is to provide an improved steam generator suitable for the generation of steam at a relatively slow rate, for use in the practice of the therapeutic treatment outlined above. Another object is to provide such a steam generator which is of relatively simple and inexpensive construction yet thoroughly dependable in operation. A particular object is taprovide such a steam generator which may utilize a conventional one gallon glass jar as a water reservoir for supplying water continuously to the generator. A further object is to provide a generator having a novel and improved temperature control means through which the temperature of the vapor delivered from the generator may be adjusted Without varying the rate of generation of steam. To this end, the invention contemplates the use of valve means for mixing air with the steam coming from the generator, at a rate that is adjustable to bring the temperature of the delivered vapor to any selected level.
Oher objects will become apparent in the ensuing specification and appended drawings in which:
Fig. l is a perspective view showing my improved therapeutic treatment apparatus in position for use in connection with a treatment cot;
Fig. 2 is a perspecive view of the vapor delivery p Fig. 3 is a transverse cross sectional view of a portion of the pad;

Fig. 12 is a face view of the temperature regu lator;
Fig. 13 is a diagram of the temperature control circuit; and
Fig. 14 is a sectional view of the inlet of another modified form of the pad.
Referring now specifically to the drawings in detail, Fig. 1 illustrates the general arrangement of my hydrotherapy apparatus, ready for use. The vapor delivery pad, indicated generally at I0, is laid upon the supporting surface of a treatment cot or bed II in a position where the patient may lie upon the pad, with the pad directly beneath the area to be treated. A steam generator, indicated generally at I2, is positioned upon the floor besidethe bed and is connected to the pad It by a flexible tube I3.
The pad I has a cover I4 in the form of an envelope of heavy terry cloth (such as is used in Turkish towels) .or equivalent material, which aids in the distribution of the heated vapors to the body of the patient and provides a relatively soft surface for the patient to rest against, avoiding the harshness of direct contact with the pad itself. The envelope I has a mouth to receive the pad, and this mouth may be closed about the inlet neck I of the pad by means of a draw string I6.
In the practice of my improved therapeutic method, the patient lies upon the pad I0. Generator I2 is regulated to supply a constant stream of moist heated vapor or steam at a selected temperature which is deemed proper for the treatment of the particular patient, and the heated vapor is delivered from the pad It, through cover I4, at a relatively uniform rate over a selected treatment period. The treatment is particularly useful in giving relief to sufierers from arthritis, polio and other ailments for which damp heat has been found beneficial.
The pad I6 is of a tough, highly flexible materal such as softrubber, resistant to the corrosive action of heated water vapor. Some of the flexible plastics of the thermoplastic type (e. g. the vinyl and acrylic resins) may also be suitable. To facilitate the construction of the pad, it may be formed in two sections, including a flat, imperforate bottom I1 and a formed or molded upper section IS. The upper section I8 has a series of parallel hollow ribs I9 each cooperating with bottom I I to define a steam duct 20 extending longitudinallytherethrough. The ribs I9 are spaced apart to define regularly spaced external grooves or channels 2|, and are provided with a series of outlet apertures 22 which deliver the heated vapor from the ducts 20 into the channels 2|. The channels 2 I, opening upwardly, deliver the heated vapor directly to the body of the patient lying upon the pad. Passing through the cover I 4, the vapor spreads laterally from the channels 2| so as to be distributed fairly uniformly to the patients body.
The ribs I9 have walls of sufficient thickness so that they will support the patients body without collapsing to such an extent as would materially restrict the even distribution of vapor through the apertures 22. The heated water vapor enters the pad through the neck I5, which communicates with ducts through a manifold 23 fanning outwardly from the neck I5. Manifold 23 defines a plenum chamber 24 which gradually diminishes in cross sectional area from inlet neck I5 to its respective extremities.
To avoid collapse of the plenum chamber 24 under the patients weight, it is provided with pillars 60 extending between and integrally united to its top and bottom walls.
To produce a uniform vapor distribution and temperature over the entire area of the pad, the outlet apertures 22 may be spaced gradually closer together toward the closed ends of the ducts, as shown in Fig. 5. Also, the ducts may be tapered in cross sectional area from maximum area adjacent manifold 23 to minimum area at the closed outer ends thereof as shown at 20' in Fig. 6. As an alternative to the close spacing of the holes, shown in Fig. 5, the diameters of the apertures may be graduated from one end to the other of the pad, as shown at 22' in Fig. 7. As a further means of attaining uniformity of delivery of the vapor over the entire area, the apertures 22 may be staggered on the respective sides of the ribs I9, as indicated in each of Figs. 5, 6 and 7.
The invention contemplates the possibility of supplying steam to the pad from a steam line of a steam heating system, in which case the safe operation of the pad could be insured by the utilization of pressure and temperature regulating valves in the line leading to the pad.
A temperature regulating valve that has been found to operate satisfactorily is shown in Fig. 14. The valve, indicated at 6, is simply a butterfiy valve, pivotally mounted in the neck I5 and controlling the rate of flow of vapor into plenum chamber 24.
As a preferred means of preparing heated vapors for the pad, I have shown in Figs. 9-10 of the drawings a steam generator which embodies a casing 25, an annular generating chamber 26 therein, a water distribution sump 21 disposed within the inner periphery of the generating chamber .26, a water reservoir 28 for supplying waterto the sump 2I, an annular heating element 62 for heating the water in the generating chamber 26, and an annular collector hood 29 for receiving the generated steam and directing it, through an outlet connection 30, to the tube I3.
A feature of the generator is the compact coaxial arrangement of generating chamber 26, sump 21 and reservoir 28. Casing may be of cylindrical shape, with a bottom 3| supported upon legs or a ring 32 of insulating material, and having a sheet of asbestos 33 insulating its inner surface against the too rapid dissipation of heat from the casing. The cylindrical wall of casing 25 is attached to bottom (H and extends upwardly therefrom, its upper edge providing a support for the generating chamber 26.
Generating chamber 26 is of U-shaped cross section, including an annular flat bottom wall rests upon the upper edge of casing 25. Inner wall has a corresponding shoulder 39. C01- lector dome 29, which is of inverted U-shape in cross section, has its lower edges resting upon shoulders 38 and 39 respectively. Walls 35 and 36 are preferably slanted downwardly and inwardly so that the generating chamber may be separated from the wall of casing 25 by an air space to minimize heat losses through the side of the casing. Collector dome 29 is of varying height, sloping from a minimum height at a point diametrically opposite connection 36 to maximum height at connection 30. This facilitates the thermo-convectional flow of steam within collector dome 29 to outlet connections 30.
Sump 21 is connected to generating chamber 25 by one or more tubes 40 bridging the annular space between sump 21 and chamber 26. At its upper extremity, sump 21 is provided with an outwardly extending shoulder 4! upon which rests an annular, cushioning seat 42 for the shoulder 43 of reservoir 28. The seat 42 may be a length of tubing of soft rubber or the like, flexed into annular shape. Sump 21 has a rim portion 5| extending upwardly from shoulder 4| and is secured in any suitable manner, as by silver soldering, to the upper portion of inner wall 35 of the generating chamber. This provides the support for sump 21.
Attached to the mouth of reservoir 28 (which may be a conventional glass jar of gallon capacity) by means of a conventional cap 44, is a nozzle 45 through which water is delivered from the reservoir into the sump 2T, maintaining a level determined by the lip of the nozzle. A corresponding level will automatically be maintained in generating chamber 26.
Heating unit 62 is of the electrical resistor type, in the form of a flat ring having ametal casing held in snug contact with the bottom wall 34 of generating chamber 28 by means of a bar or spider 45 pressing upwardly thereagainst. The center of bar 35 is attached to the bottom of sump 21 by means of a stud 46 the head of which is silver soldered or otherwise suitably secured to sump 21, and a nut 41 threaded onto stud 45. As shown, bar 45 is of channel section.
Control over the temperature of the vapor delivered from the generator may be effected either through the use of conventional thermostatic control mechanism, regulating the operation of heating element 28, or through the mixing valve shown in Fig. 11 which operates to admit a variable flow of air into collector dome 29 for mixture with the steam therein, to moderate the tempera ture thereof. In a side wall of dome 29, preferably the inner wall, is a series of air inlet apertures 48 adapted to register with corresponding apertures 49 in a valve member 55. Valve member 50 may be in the form of a ring or, as shown, a segment of a ring, engaged against the inner wall of colletcor dome 29 and resting upon the upper edge of inner wall 35 of collector chamber 26. By any suitable means, such as for example, handle 52, valve member 49 may be rotated to partially or fully close apertures 43. Within collector dome 29, a deflector baffle 53 is positioned in spaced relation to apertures 18, deflecting the steam currents rising from generator 28 so as to create suction in apertures 28, resulting in outside air being drawn through apertures 48 into the dome 29, as indicated by the arrows in Fig. 11.
Fig. 11 illustrates a theromstatic control embodying a thermostat 54 attached to the outer wall 36 of the generating chamber so as to respond directly to the temperatures in this chamber. Thermostat 54 operates to interrupt the circuit to the heating element 62 when the generating chamber reaches a selected maximum tem 5 perature, and to restore the circuit when the temperature in the generating chamber drops a predetermined increment below such maximum temperature. To this end, the thermostat is arranged in series in the power supply circuit including conductors 55 and 58, between a connector 51 (for plugging into a conventional electric outlet) and the heating element 62. A conventional heat control adjuster including a knob 58 cooperating with an indicator dial 59 on casing 25, is utilized to set the thermostat 54 for operation at selected temperatures within a predetermined range.
One of the chief advantages of my invention is the concentration of treatment to the exact area of the body which requires the treatment. This is accomplished, in my improved method, by resting the patients body directly upon a supporting surface having, as a component. part thereof, a vapor delivery pad provided with a series of outlets, and adjusting the pad so as to register with the area to be treated. The area of the patients body extending beyond the margin of the pad will, under the weight of the body, sag into substantial sealing contact with the supporting surface around the pad, and thus there will be a tendency to confine the vapors in a pocket defined by the impression of the pad in the patients body. This results in a greatly improved efficiency of treatment. I am of course aware that the broad idea of applying heated vapors to a patients body through a pad havin a series of vapor outlets, has been previously proposed, but in each instance where attempt has been made to utilize this broad principle, so far as I am aware, there has been a failure to appreciate the possibility of concentrating the application of vapor to the area to be treated, and greatly improving the efiiciency of the action of the vapor on such area, by resting the patients body on a supporting surface including the pad as a component part thereof.
Fig. 8 shows a modified form of the invention in which a pad Illa is preformed to a spirally rolled form for use in treating a patients limb (e. g. an arm). The pad is suificiently flexible to permit of its being adjusted to a larger or smaller diameter as required. It may be secured in place about a limb by fastener straps having button holes (not shown) to receive buttons 66 anchored in the outer side of the pad.
