' This invention relates to improvements in Inc-rectal dilators, particularly adapted to housed in connection with the treatment of those diseases and disorders of the-ano-rectal 6 canal which are characterized by a spastic or sphincter muscle, and where it is desired to expand and dilatein adefinite manner and to a definite degree, the walls of sand anal canal.
. An object of this invention is to limit the 10' expansion of the dilator so that there is no danger oftearing or rupturing the tissues to be expanded.
Another object is to control the d lator so that it will assume a predetermined shape conforming to the natural shape of the organs to be treated.
j Another. object is to have the dilator so constructed, because of its predetermined contour, that it may be accurately in place for prolonged periods of time when used for treatment.
It is well known in the art to have a di-- lator which is expansible due to air or fluid being forced into the' dilator under ressure, but, so far as the applicant knows, it is new and novel to limit this expansion by the use of a contour bag of non-expansible material, and, further, to so shape this bag that a predetermined shape will be obtained.
A further object of this invention is to provide means whereby the diseased part may be subjected to treatment at different temperatures, it being very desirable in the treatment of certain anal and rectal diseases to 85 have the dilation of these organs accompanied by such thermal effects as may seem proper, and by the use of this device, low degrees of temperature, and at other times, higher degrees of temperature may be used at will in the treatments for which this dilator is desi ned.
Other 0 'ects of this invention will appear from the ollowing detailed description of the device and as disclosed in the drawings which are herewith made a part of the application.
In the drawings Figure 1 illustrates an elevation of the assembled rectal dilator with a section taken through a portion thereof.
Figure 2 illustrates a section taken along line 2-2 of Figure 1.
Figure 3 is a section taken along line.
3-3 of Figure 1.
. invention. a
Figure 4 is a section taken along line 4-4 Y of Figure 1.
Figure 5 illustrates a modification of this Figure 6 illustrates a sectional view of F igure 5 taken along line 6-6. I
eferring to the drawings, like numerals designate s1milar parts.
Numeral 1 refers to a firm rubber core having achannel 2 running part way the length of said core, with an opening 3 at its inner- 5 most extremity, and an opening 4 at its outermdst extremityi A valve 5 is located at its outermost extremity. A flange 6 is adjacent the outermost opening for the purpose of securely holding in place a rubber tube 5 connected-to a bulb 6. y
Attached to the firm core 1' is a soft rubber bag 7, which is in turn encased 'by contour.
. bag 8 of a non-elastic material. The contour,
bag is in turn encased bya bag-,oflthe samematerial as the bag 7. These bags are se curely held together with no space between them at 10 and 11.- A one-way valve 12 is shown at the outermost end of the passage 4.
As generally used, the dilator is inserted in so a deflated. condition, the small end 11 being inserted in the member desired to'beexercised, the soft protective coverin 9' ofl'ering 'very little resistance. Fluid is hen forced into the bag 7 by means of pressure-bulb 6,
through the passage 2, which causes the bag 7 to expand until it reaches the extremity of the bag 8. By having the contour bag formed, as shown in Figure 1 of the draw-' ings,-with two bulges on either side, of a less distended portion, the dilator is held firmly in position without danger of slipping out or in. It can easily be seen that the shape of the bags 7 and 9 will be controlled by the shape of the contour bag 8. After insertion and dilation, the rubber tube 5 may be removed from the dilator and the same left in the diseased part as long as desired. When it is desired to remove the dilator, the valve 5 KONG-E LLOYD OOR- time, subject the member being treated to the desired temperature.
Figure 5 lllustrates a modification in con: struction over Figure -1 of this invention, wherein numeral 13 designates a receptacle made of any suitable material such as rubber, adapted to encase aba 14 preferably made of non-elastic materia. These two receptacles or bags are arranged to encase a bag 15 which in turn is suitably attached to a core portion 16, all arranged in a similar manner to the construction disclosed in Figure 1. The main distinction between the structure disclosed in Figure 5 over that shown in Figure 1 lies in the arrangment of a core portion 16 and an inner to ular element 17 made of suitable material, the tubular portion 17 extending in open communication with the bulb 18 and held in operative relationship between the core 16 and the bulb 18 by means of a core portion 19. From the hollow core element 16 is adapted to extend in open communication therewith a valve 20 for allowing the air, liquid, or otherwise to flow or exhaust from the device,
Having described my invention, claim as new and novel is:
1; A dilator comprising a core, an expansible member mounted on said core, means for expanding said expansible member, and means comprising a casing for limitingsaid expansion.
2. A dilator comprising'a core, an expansible member mounted on said core, a nonexpansible member enclosin said expansible glember, and means for i ating said memers.
what I 3. A dilator comprising a core, an expansible member mounted onsaid core, a nonexpansible member enclosing said expansible member, a protective coverlng enclosing the said members, and means for inflating said members.
4. A dilator comprising a core, an expansible member mounted on said core, a nonexpansible member enclosing said expansible member, a protective covering enclosing the said members, and means for inflating said members, other means for deflating said members.
5. A dilator comprising a core, an expansible member mounted on said core, a nonexpansible member, said non-expansible member surrounding and limiting the expansion of the expansible member having its middle sectionof less width than the adja-' cent sections.
6. A dilator comprising a core, an expansible member mounted on said core, a nonexpansible member, said non-expansible member surrounding and limiting the expansion of the ex ansiblemember havingits middle section oi less width than the adjacent sections, a protective covering enclosing the other members.
7. A dilator comprising an expansible member, a non-expansible covering for said expansible member, said non-exp ansible cover limiting and forming the contour of the expansible member and means for inflating said expansible member.
In testimony whereof I aiiix my signature.
