Continuation of application Serial No. 430,215, February 10, 1942. This application filed May 27, 19%, Serial No. 537,604 V This application is a continuation of my copending application Serial No. 430,215, filed February 10, 1942.

My invention relates to electrotherapy, and has for its general object to provide improved means for administering such treatments, and particularly to provide means whereby electrotherapy may be combined with the application of compresses to exert beneficial effects upon the skin of the patient, as well as to facilitate the flow of electric current through the skin.

The application of electric current of low voltage and constant amperage to the human body for remedial purposes is well known, and to apply moist compresses to parts of the body such as the face in order to obtain beneficial effects upon the skin and subcutaneous tissues and muscles is also well known. I have discovered that a com bination of the two different treatments gives particularly beneficial results and that they sunplement one another.

The effect of the low voltage constant amperage current flowing through the body, as for instance from an electrode positioned on one side of the body to an electrode positioned on the opposite side, is stimulating to the blood circulation in the skin adjacent the electrodes and to the whole anatomy traversed by the current, provided, of course, that the voltage and amperage of the current are of proper value.

The effect of the current in passing through theskin adjacent the electrodes is to warm theskin and stimulate the circulation of blood through,

the capillary blood vessels. Since creases and wrinkles in the skin are in large measure due to poor condition of the skin, this stimulation of the circulation aids in restoring the tone of the skin, and when moistened cloths are pressed upon the skin over the same area during the electrical treatment, the reduction of such wrinkles, with stimulation of glandular action and cleansing of the pores of the skin is facilitated.

The treatment of the skin of the face is given by way of one example of the application of the invention, but it is to be understood that the invention is not limited to such use.

An, object of the invention is to provide an improved means for applying electric treatments particularly to the facial areas of patients.

A further object of the invention is to provide an improved mask for application of galvanic or low tension direct current to the skin.

A still further object of the invention is to provide a simple and inexpensive yet efiicacious mask of the kind referred to. i

20 Claims. (cries-#380) Itis also an object of the invention to provide a facial mask which serves'both to facilitate the application of direct current electricity andlow voltage to the face ofa patient while at the same time acting to apply a compress to'the face.

Another object of the invention is to provide a mask provided with weights acting both to hold" the mask firmly upodthe faceof a patient and also to exert a smoothing orstretching eifect on the skin of the face tending to aid in removing wrinklesand creases. T i Still further features of the invention will hereinafter appear in the following description taken in conjunction with the accompanying drawings in which a preferred embodiment of the invention is shown by way of example. It is to be understood, however, that the scope of the invention is not limited in any Way by this illustrative embodiment, but only by the scope of the appended claims.

In the drawings, in which identical numerals indicate identical parts,

Fig.1 is a side view of a patient undergoing an electrotherapeutic facial treatment using the means of my invention, 7

Fig. 2 is an end view on an enlarged scale of the mask shown in Fig. 1, certain parts being shown in section,

Fig. 3 is a plan view of the means of my invention formed as a facial mask and opened out to lie in one planewith the side positioned in use next the patients skin uppermost, and

Fig, Lisa cross-section on the line 4-4 of Fig. 3.

While the different effects upon the skin and tissues of the electric current at the positive and negative terminals are not fully understood, the

a general effect of stimulation of the flow of blood through the small blood vessels of the skin, and the soothing and relaxation of the nerves and muscles in the area traversed by the current in its path from positive to negative electrode are generally conceded.

While I have shown the current as flowing into the mask and returning from the opposite side of the 'patients head, I do not confine myself to arranging the apparatus for a particular direction of flow of the current, the best direction of flow being a matter which can be determined by experiment to determine the best results for the particular condition sought to be alleviated.

The particular characteristic of the current such as one of fluctuating value, or of various voltages and values of amperage is also a matter that'can' be chosen to afford the most benefit to the patient according to his particular condition.

In the drawings, It! indicates a flexibl member shaped by suitably cutting the material from which it is made so that it may closely follow the contour of the part of the body to be treated. In the embodiment of the invention shown, which illustrates a mask designed to treat the skin of the face, particularly that of 'the forehead, chin and cheeks, the flexibl member is provided with a cutout portion leaving the eyes, nose and mouth of the patient clear, both for the comfort of the patient, and to enable the most beneficial effect to be obtained as will be more fully explained hereinafter. W

The mask I is fitted with a clip or terminal I I for the attachment of the positive lead [2 leading from a suitable source of power, not shown, such as a bank of electric batteries furnishing a direct current of suitable amperage and voltage. The current flows through conductors provided, as later described, inthe mask l0,'through the skin and tissues of the face, and leaves through a pad l I under the patients back to return to the source of electric powerby the return lead I A which is indicated as connected to the pad [3 which may have an electrically conductive surface such as of woven or braided metal wire cloth, or may be rendered sufficiently conductive by the covering thereof being kept in a moistened condition.

A piece of fabric or cloth I9, preferably cut out similarly to the mask I0, is -positioned between the mask and the skin of the patient. This piece of material is of moisture absorbent material and serves an important purpose as will appear later.

The mask'l 0 is preferably formed by two pieces of material of identical contour, the inner layer l6 (Fig. 4) being of pliable nonconductive and water resistant material such 'as rubber, while the outer layer I8 may be of a tough and relatively heavy material serving togive body to the mask. I have foundthat woven asbestos cloth serves well for the purpose.

The inner and outer layersof the mask may be secured together, after assembly, in any suitable manner, as for instance by the use of an adhesive, or by stitching.

The electric current isled from the clip H through conductors 22, which are preferably made from insulated fine wirecable to obtain flexibility of the conductors, and positioned between the inner and outer layers of the mask to electrodes 20 (Fig. 4-). These electrodes each comprise a head 36 arranged between the inner and outer layers of the mask, and a stem portion 32 passing through-the inner layer 16 of the mask. A face 36 is mountedupon stem 32 tolie against the face of the inner layer next the skin of the patient. Washers 36 and 31 are arranged under the head 38 and face 34 of the electrode and serve to grip between them the inner ,layer 16 adjacent the stem, and to properly position the electrode. Washer 36, between head30 and the inner layer I5, is provided with lugs for securing the ends of conductors 22, a similar washer being arranged in connection with clip H. The specific construction of the electrodes described has been found to be satisfactory, but it will be evident that various changes in construction may be made therein.

The manner in which the electrodes are spaced and electrically connected is clearly indicated in 3 in which it will be seen that the electrodes are arranged in a ring around the cutout portion of the mask, the electrodes being linked together by lengths of conductor 22, but other. arrangements of conductors and electrodes may be made that will assure a good distribution of the discharge from the electrodes into the material I!) positioned over the face of the patient, and which will supply all electrodes with electric current from clip or terminal II.

The flexible member or mask is formed so as to secure an efficient contact of the electrodes and fabric over the areas to be treated and in addition to the flexibility obtained by reason of the cutout portion already described, is provided with laterally extending flaps 24 to which weights are attached. The weights may be of any desired form" and arrangement, but th preferred construction is that shown in Fig. 2 and consists of pockets 25, provided for instance by leaving the outer and inner layers uncemented over a definite area and filling the space thus provided with lead I shot, indicated by the numeral 28. The weight of the lead shot is made suflicient to not only draw the mask and moistened fabric evenly and firmly against the patients face, but also to exert a pulling effect on the sides of the face and forehead tending to smooth and help to reduce wrinkles and creases in the skin. It will be noted that the mask around the cutout portion engages the sides of the face toward the jaw line, thus ensuring the application of pressure at the proper points to secure the aforementioned result.

The skin offers the greater portion of the resistance to the passage of the electric current and the moistened fabric element l9 serves to reduce this resistance by keeping the skin moist and to diffuse the electric current over the skin. In addition the fabric may carry medicinal lotions in themselves beneficial to the skin, and thus enhance the effectiveness of th treatment.

It has been found by actual practice that my invention provides a novel and beneficial electrotherapeutic treatment, but various modifications of the flexible element or mask, and variations in the type of electric current used, or in the values of voltages and amperagesutilized may be made without departing from the scope of the invention as defined in the appended claims.
