INVENTOR, Claude QRowe,

Patented Apr. 27, 1937 UNITED STAT$ OFFICE.

Claude 0. Rowe, Santa Monica, Calif., assignor of one-half to Louis Janisky, Les Angeies, Calif.

Application July 29,

1 Claim.

My invention relates to improvements in internal orifice thermal dilators and medicators, and has for an object to provide an electricallyheated, defiatable and inflatable instrument for insertion in the orifice to be treated when doflated and warm, and subsequently inflated and heated while in place.

Another object of my improvement is to provide defiatable flutes in the surface of the instrument for filling with medicated paste which may be applied to the orifice walls by inflating the instrument while in place and then heated.

Another object of my improvement is to attach an easily operable rheostat to the instrument for thermal control.

I attain these and other objects of my improvement with the device illustrated in the accompanying sheet of drawing, forming a part of this application, in which Figure l is a side elevation of the interior inflexible part of my device shown with the attached rheostat in section on a vertical longitudinal plane, Fig. 2 is the front end elevation of Fig. 1, Fig. 3 is a view similar to Fig. 1 in which a rubber sack is shown in place over the insertable part or" the device with flutes formed in the sack and filled with medicated paste, Fig. e is a crosssection of Fig. 3 on the line 3-6. Fig. 5 is a cross-section of Fig. 3 on the line 5-5, Fig. 6 is the same view as Fig. 3 with the rubber bag inflated, and Fig. '7 is a front end elevation of Fig. 6.

Similar characters refer to similar parts throughout. Certain parts are broken away to show other parts hidden thereby.

With more particular reference to designated parts: The body of the instrument a ribbed structure of cylindrical shape consisting of the outer annular end 8 and the inner tapering end ll joined by the spaced ribs 52 with intervening spaces Ill. The hollow cylindrical handle Q has the closed front end 9 which is fastened in the annular end 8 of the instrument body. The outer end of the handle is closed by the screw plug I3.

The electrical heating element I iis extended through a central hole in the closed end of the handle and extends within the ribbed body of the instrument where its front end is disposed near the closed front end of the instrument.

The terminal wire l5 of the heating element is disposed in the longitudinal groove 9 in the inner wall of the hollow handle 9 and passes through an opening therein and is for connection with an electric service wire not shown.

1935, Serial N0. 33,669

The other terminal wire it of the heating element is disposed in the handle groove 9 and connected with the outer end disc ii. There are four rheostat coils l8 with three intervening discs !9, which, together with the said outer end disc IT and the inner end disc 20 constitute the rheostat assembly disposed within the hollow handle 9. Each terminal of each of the coils i8 is connected to its adjacent disc. The assembly of coils and disc has a central longitudinal hole.

The rheostat control rod 2| is formed of electri insulation and is extended through a central hole in the screw plug l3 and protrudes both externally and internally therefrom. The outer end of the rod has the handle 22 thereon and the inner end thereof has the contact brush 2 thereon. The electric wire 23 extends through a central longitudinal hole in the rod and its inner end is fastened to the brush 24 while its outer end is connected with an electric service wire not shown.

When the said rod and appurtenances are in their solid-line positions, the brush 24 is disposed in a space within the handle near its inner end out of contact; but as the rod is withdrawn the brush first contacts with the inner disc 29 and then with each successive disc till it reaches its outermost position at 24' where it contacts the outer end disc ll, when the rod is at El, the rod handle at 22 and the terminal wire at 23'.

The construction provides for an open heating circuit when the rod 21 is in its solid-line position, for a closed circuit through the entire rheostat r sistance when the brush contacts disc 26, for the elimination of each rheostat coil in turn as the brush successively contacts each disc is, and for the elimination of the entire rheostat resistance from the heating circuit while the brush 20. contacts the disc IT at its position 24'.

There is an opening 25 through the closed inner end of the hollow handle 9 in which the hose tube 26 is fastened. The hose 21 is fastened on the tube 26 and connected with a vacuum air pump or with a compressed air pump, as desired, but not shown.

The instrument 8, ll, i2 is extended into the rubber sack 28 having the restricted, beaded,' open end 23 which closely fits around the inner end of the handle 9 to hermetically seal the same against the admission of air therebetween. The sack 28 preferably is of thin rubber and is larger than the instrument body, providing for the folds of the sack at 28* between the ribs l2 and in the spaces Ill. These folds may easily be made in the sack and they provide flutes into which the medicated paste. 2!] is placed. A convenient Way to make and retain the folds or flutes 28 is to connect the hose 21 with a vacuum pump and exhaust the air from the interior of the instrument body and the sack, when the rubber fullness of the sack is drawn into the openings I and thus the flutes will remain till the vacuum ceases.

'In operation: It is assumed that the rheostat rod 2| is in its solid-line position, opening the electric circuit of the heating element; that the heating wires l5 and 23 are connected with a source of electricity, and that the rubber sack is in operative position over the instrument body with flutes therein as shown in Figs. 3 and 4. If it is desired to apply medicine to the walls of the parts to be dilated, a paste containing the desired medicament is placed in the said sack flutes and the instrument is extended into the orifice to be treated. Then the rheostat handle and rod 22, 2| are withdrawn till a suitable current of electricity flows through the heating element to provide the desiredtemperature in the instrument and the hose 21 is connected with an air compressor or compressed air tank which causes the sack 28 to be dilated, as shown in Fig. 6, while in the orifice and, in addition to the benefit to the adjacent tissues of the pressure and temperature thus applied, the medicated paste 29 is melted and distributed over the tissues in a more complete, efiective and simple manner than hitherto possible. If the temperature supplied by the instrument becomes excessive, it is reduced by moving the rod 2| inward; if greater temperature is desired, the rod is moved outward, and if it is desired to shut off the heating current, the rod is pushed in till stopped by the handle 22 bearing on the screw plug I3. If it is desired to modify the dilating pressure, the source of compressed air is controlled to effect the desired change.

At the completion of the treatment, the electric current is shut ofi, as explained, the compressed air is shut off and the sack deflated by disconnecting the hose 2'! from the source of compressed air, and the instrument is withdrawn from the orifice.

Although not essential, as stated above, the said flutes in the sack are conveniently formed by connecting the hose 2! with a vacuum pump and maintaining a vacuum in the instrument till the same has been inserted in the orifice being treated.

Having thus disclosed my invention, what I claim as new therein and desire to secure by Letters Patent is,-

An orificial treating device including, a relatively long ribbed body having a closed tapering front end and an open annular rear end, a hollow cylindrical handle having a closed front end extended and fastened in the said annular rear end of the ribbed body and an open rear end, a bearing screw plug closing the rear handle end, an electric heating element extended through an opening in the. said closed handle end and disposed within the said ribbed body, rheostat resistance coils disposed in the said hollow handle, a rheostat control rod mounted for reciprocation in the said bearing screw plug, a brush fastened on the inner end of the said rod adapted to contact with the terminals of the said resistance coils and to pass out of contact therewith as the said rod reciprocates in the said bearing, an electric wire fastened to the said brush and extended through a central opening in the said rod protruding from the outer end thereof, an electric wire connected with one terminal of the said heating element and extended through the Wall of the said handle to the exterior thereof, an electric wire connected to the other terminal of the said electric heating element and to the said resistance coils, a hose tube extended through the closed inner handle end from the exterior of the handle, and a thin rubber sack loosely disposed over the said ribbed body, having a constricted beaded open end disposed to tightly encircle the inner end of the said handle, adapted for disposal in flutes between the said ribs to hold medicaments.
