Description:

18 Claims. (CI. 1 This invention relates to electro-therapeutics us and has for its object the provision of an im- o0 proved process for treating pathological conditions such as post-operative pains, dry sockets, sh following the extraction of teeth and general ex surgical operations intraorally and extraorally, treatment of antrum, gingivitis, bleeding gums, th pyorrhea, trench mouth, canker sores, and in- te fected glands related to mouth. ti Generally stated, the process consists of a definite technique consisting of successive steps st to bring about a result by means of a galvanic a current resulting in a healthy condition through el the flow of electrons producing an ionization by means of the galvanic current, hereinafter de- el scribed and defined in the claims.

The nature of the process and the preferred 0 form of the apparatus is illustrated in the accompanying drawings wherein like characters indicate like parts throughout the several views. g Referring to the drawings: Fig. 1 is a view principally in perspective showing, by means of broken lines, the bust of a i person and by means of full lines, the improved i apparatus partly applied thereto for an intraoral treatment, together with a wiring diagram; Fig. 2 is a view principally in section taken on the line 2-2 of Fig. 1, on an enlarged scale; Fig. 3 is a perspective view of the tray removed from the matrix, as shown in Fig. 1; Fig. 4 is a fragmentary view principally in section showing the jaws of the person closed into a plastic material in the process of making a matrix in which is invested, between said jaws, a tray holding a positive electrode and a moisture-absorbing pad; Fig. 5 is a perspective view of the completed matrix; Fig. 6 is a view corresponding to Fig. 1 but showing the completed matrix returned to the mouth of the person, together with a terminal for the positive electrode; Fig. 7 is a perspective view of a tray invested in a matrix used in the treatment of a tooth socket; Fig. 8 is a view corresponding to Fig. 6 but showing the matrix and the tray, illustrated in Fig. 7, in the mouth of the person; 50 Fig. 9 is a view corresponding to Fig. 3 but 5showing a slightly different shaped tray; Fig. 10 is a perspective view of a tray used when taking an impression in the process of making a matrix for the entire upper Jaw; Fig. 11 is a bottom perspective view of a tray L28-409) ed when taking an impression in the process making a matrix for the entire lower jaw; Fig. 12 is a view corresponding to Fig. 8 but owing the terminal for the positive electrode tending into the antrum cavity; Fig. 13 is a view corresponding to Fig. 8 with e exception that the lower jaw has been omitd and showing a simplified form of the posive electrode; Fig. 14 is a view corresponding to Fig. 4 but lowing a matrix for a section of the lower jaw nd a different method of holding the positive ectrode and its terminal; Fig. 15 is a bottom perspective view of the Fig. 16 is a view showing in diagram a portion f a person's head together with substantially he same apparatus as shown and applied in lig. 6 with an attachment for simultaneously iving an extraoral treatment through the nose. Referring first to the invention, as shown in Iigs. 1 to 6, inclusive, the bust I I of a person s diagrammatically illustrated by broken lines n Fig. 1 for the purpose of showing one form of the apparatus as applied for giving an intraoral treatment. This apparatus includes a positive electrode 18 and a negative electrode 19 and the source of electrical energY therefor, as shown in the wirifg diagram in Fig. 1, is as follows, to wit: The letter T is a transformer haing a primary 20 connectible to a suitable source of supply of alternating current, a center tapped low voltage secondary 21 and a center tapped high voltage secondary 22. The alternating current output high voltage secondary 22 is rectifled by means of a suitable rectifying device such, as shown, a full wave vacuum tube rectifier V, and which rectifier includes a filament 23 and a pair of like plates 24. The filament 23 is energized by the low voltage winding 21 and which filament is connected by leads 25 to opposite sides of said winding. The direct current output from the rectifier V is taken from the fament circuit by a lead 26 extending from the center of the filament supply or low voltage secondary winding 21. This lead 26 is the positive direct current lead from the rectifier V and the high voltage secondary 22. As a means for obtaining a variable voltage from the power sup- 50 ply unit a voltage divider P, iii the form of a potentiometer, is connected between the extreme positive and extreme negative leads 26 and 21, respectively. C represents a filter condenser interposed between the extreme positive and extreme negative leads 26 and 27 for the purpo of reducing the ripple. One of the service lea 28 ,is taken from the high voltage end of tl voltage divider P and has interposed therein current meter M and the other service lead is taken from and returns to the sliding arm of the potentiometer. When the apparatus used the voltage and current is regulated I sliding the arm 30 toward one extreme or tl. other of the voltage divider P.

As shown, the leads 28 and 29 are insulate wires and the positive electrode 18 is detachabl connected by a separable coupling 31 to the wir 28 and the negative electrode 19 is likewise con nected by a separable coupling 32 to the wire 2! The negative electrode 19, as shown, is a thi? plate of tin, zinc or other suitable metal, is shapei for application to the cervical region on the bac of the neck and is held in place by a collar 3U o rubber or other non-conducting material. Thi collar 33 has a central depending portion, th inner face of which is recessed to receive the nega tive electrode 19 which is secured to said collar b any suitable means, see Fig. 2. One member o: the separable coupling 32 is fixed to the back o: the negative electrode 19 at the center thereof anc extends rearwardly through a hole in the collai 33. Said collar 33 is held in place about the neck of the person 17 by a strap 34 which extend, through apertures in the end portions of said collar and the ends of the strap 34 are connected by a separable fastener 3 5.

The exposed face of the negative electrode 19 is covered by a conductor pad 36 of felt or other 85 suitable moisture-absorbing material that has direct contact with the tissue to which it is applied and prevents burning thereof by the electrode 19. Said conductor pad 36 is stitched or otherwise secured to the negative electrode g8. The shape of the collar 33 and the material from which it is formed holds the pad 96 in contact with the tissue throughout its entire area and under the desired pressure. The pad 36, which contains the proper amount of moisture, acts as a conductor between the negative electrode 8s and the tissue.

The positive electrode 18, as shown in Fig. 3, is a thin plate of copper or other suitable metal and is in the form of a trough that is mounted on the inner face of a correspondingly formed tray 31 which is recessed to receive said electrode.

The tray 37, at its marginal edge portion, extends outwardly of the positive electrode 18. One member of the separable coupling 38 is formed with one end of the positive electrode 18 and the tray 37 has at one end a short tubular stem 38 in which said coupling member is housed.

A moisture-absorbing conductor pad 39, of felt or other suitable material, is applied to and covers the outer face of the positive electrode 18 and is secured in place by any suitable means. This Pad 39, in addition to acting as a conductor, also affords a reservoir for supplying moisture to a terminal for the positive electrode 08, as will presently appear.

The positive electrode 18, its conductor pad 38, and the tray ST are invested in a matrix 50 formed from well-known dental compound used in taking impressions. The first step in making the matrix 40 is to heat the compound until pliable, invest the tray 37, the positive electrode 18 and the conductor pad 39 therein and place said compound in the mouth bet,.- en the upper and lower jaws 41 and 42, respectively, at the point where a treatment is to be given, which, as shown, is for se pyorrhea, as indicated at U3. The person then ds bites into the compound to make an impression of ae certain of the upper teeth and surrounding tissue. a The compound is then removed from the mouth 0i and a hole cut therein, as indicated by the nu- 6 30 meral 45, and extends through the matrix from is its inner side to the conductor pad 39. The size ey of this hole J4 is such as to expose the area, indiie cated by the numeral 43, to be treated and in forming said hole the operator is guided by the 1i d impression of the teeth in the matrix 136 to propy erly locate said hole.

'e It is important that the hole 44 does not expose S any of the teeth when the matrix is in position . and it is also important in making the impression 16 a that the person does not bite completely through d the compound to the conductor pad 39 so that k the respective teeth are fully insulated by the i non-conducting matrix.

s The terminal 65 for the positive electrode 8 is s placed in the hole 64 with its inner end in direct - contact with the conductor pad 39. When the 7 matrix 6x0 is in the mouth the outer end portion f of the terminal 4L is in direct contact with the f tissue to be treated, as indicated at 43. The I terminal 5 is made from a moisture-absorbing pliable material, such as cotton. Obviously this pliable terminal 65 will closely engage and be compressed by the tissue exposed through the Sopening 44. When the apparatus is properly apSplied to a person for a treatment the wire 28 is connected to the positive electrode 88 by the coupling 3 and the wire 29 is attached to the negative electrode 19 by the coupling 32 and thereafter the control for the electric circuit is manipulated to supply just the right amount of current to the positive electrode. Obviously, the electric current passes through the wire 28, the positive electrode 18, the conductor pad 39, the terminal '5 and the tissue contacted by said terminal. It is ,0 evident that the matrix M0 can be replaced in the mouth any number of times in exactly the same position with the terminal 55 in registration with the same tissue to be treated.

Referring now to the invention, as shown in Figs. 7 and 8, the apparatus is used for treating the tissue in a cavity 04 left by the extraction of a tooth. In these views the jaws, the tray, the positive electrode, and the conductor pad are designated by the same reference numerals as in Figs. 1 to 6, inclusive. The matrix 47 is made in the same manner as the matrix 40 and at the time the impression is made, the compound at the cavity 46 will project slightly into said cavity and thereby designate the point where the hole du is to be cut through the matrix to the conductor pad 39 for the terminal 59. This terminal 89 is made from the same moisture-absorbing mraterial as the terminal 45 and its inner end directly engages the moisture-absorbing pad 23. The outer end portion of the terminal 69 projects, into the cavity 56 and is in direct contact with the surrounding tissue.

Fig. 9 shows a modification of the tray and the positive electrode shown in Fig. 3. In this modification the wire 28 is coupled to the electrode 50 at the center thereof and the tray 5 has a central tubular stem 52 in which said coupling, not shown, is housed. In this showing of the invention the electrode 50 is covered with an insulating enamel except at the two areas 50' where the electrode is left exposed for contact with terminals, not shown. The purpose of this insulated enamel is to prevent a person from receiving a shock during the process of making a matrix in case he 2,056,A40 should bite completely through the compound and des onto the electrode. •mat In Fig. 10 the tray 53 and positive electrode 54 ref are designed for use when making a matrix of ture the entire upper set of teeth, the surrounding app: tissue, and edentulous mouth for treatment of duc post operative pain after extraction. The tray duc 55 and the positive electrode 56, shown in Fig. 11, duc are designed for use when making a matrix for tres the entire lower set of teeth, the surrounding tis- T sue, and endentulous mouth for treatment of post voir operative pain after extraction. sta The illustration shown in Fig. 12 is substan- sta tially the same as that shown in Fig. 3 and corre- a g sponding parts have the same reference numerals the except the terminal 58 which extends into the bur antrum cavity 59 for use in treating the parts th with which the terminal 58 contacts.

In Fig. 13 is illustrated a very simple method of forming an electrode 60 for treating the tissue in SO the cavity 46. In this illustration the outer end ha portion of the wire 28 is stripped of its insulation w1 and the bare portion of said wire is wrapped with mn a pliable terminal 61 and said terminal and elec- mI trode inserted into the cavity 46. an Before the composition is placed in the mouth OP in the process of making the matrix 62, the wire 28, the electrode 60, and the terminal 61 are so placed in the composition, as shown, so that when h the matrix 62 is finished said wire, electrode, and w terminal are positively held thereby in proper re- al lation to the cavity 46. a Referring now to the invention, as shown in P Figs. 14 and 15, the apparatus illustrated is used P' for treating the tissue on the inside of the gum a of the lower jaw 42. In this illustration a rel- 0 atively small wire 28 is used and the electrode 63 is formed in the same manner as the electrode 60 and the terminal 64 is wrapped around said 1 electrode. In the process of making the matrix t 65 the wire 28, electrode 63, and terminal 64 are r embedded in the composition, as shown. In this arrangement of the electrode 63 and terminal 64, the wire 28 may be bent and shaped so that a good portion thereof is held by the matrix 65 and in a position between the teeth to permit the jaws to be closed onto the composition.

In Fig. 16 there is fragmentarily illustrated a side view of the head shown in Fig. 1 and the electrode 18, the tray 31, the pad 39, the matrix 40, and the terminal 45 are the same as shown in Fig. 6. In this showing of the apparatus a branch coupling 66 is provided for detachably connecting the member of the coupling 31 on the wire 28 to 5 the member of said coupling on the electrode 18 and for connecting a branch positive lead wire 61 to the wire 28. The insulation on the outer end portion of the wire 61 is stripped and the bare portion of said wire affords a positive electrode 68.

The pliable terminal 69 is wrapped around the electrode 68. This electrode 68 and terminal 69 are inserted through the nose and into the natural opening in the antrum cavity 59 for treating the parts with which the pliable terminal 69 contacts or in contact with the adjacent tissue.

In the intraoral application the current is passed into the antrum tissues by means of nerves in that part in contact with the tissue connecting the anterior antrum branch of the superior maxllary nerve.

Obviously, in this form of the apparatus an intraoral and extraoral treatment are simultaneously given. The coupling 66 and the wire 61 hold the electrode 68 in its proper position and support the same from the matrix 40. All of the matrices ribed are formed in the same manner as the rix 40 and all of the terminals, heretofore rred to, are made from cotton or other mois-absorbn g pliable material. Just before the aratus is used for giving a treatment, the contor pad or pads and the conductor or contors are moistened so as to form proper contors from the electrodes to the parts to be ted.

e moisture-absorbing pad 39 acts as a reserfor supplying water to the moisture-absorbterminal 45 and keeps said terminal in subntially the same moist condition so as to afford ood conductor for the electrode 18 and prevents terminal from drying out resulting in the ning and injuring of .the tissue in contact with terminal.
