This invention relates to improvements in suppositories for the treatment of hemorrhoids.
One object of the invention is to provide a suppository by means of which the medicament carried thereby will be held directly in contact with the hemorrhoids or diseased membranes.
Another object is to provide a suppository having an improved means for holding the medicament whereby the same will be slowly applied to the diseased membranes for a long period of time during which the suppository is held in position.
With the foregoing in view the invention resides in the novel subject matter hereinafter described and claimed the description being supplemented by the accompanying drawing.
Figure l is a sectional view of a portion of the parts surrounding the rectum showing the application of the suppository.
Fig. 2 is a longitudinal sectional view of the suppository.
Fig. 3 is a perspective view of the suppository with parts broken away and in section.
In the drawing the numeral 5 denotes an inert hollow head or anchoring member which is preferably, substantially cone shaped and may be formed of wood or any suitable nonsoluble material but which is preferably formed of paraflin. The body of the suppository is in the form of a fabric tube 6, the upper' end of which is inserted into the lower open end of the head and rmly secured thereto in any suitable manner. Then the head is formed of parafin the end of the tube may be embedded in the end of the head when the latter is molded. The cavity 7 in the head above the end of the fabric tube tapers toward the outer end of the head and in said outer end and communicating with the cavity is a small discharge opening 8 the purpose of which will be hereinafter described.
The tube 6 and the cavity 7 in the hollow head are to contain the charge of medicament. This charge is in the form of a cylindrical shaped plastic mass which is inserted into the tube and hollow head, and is pre- 1228. Serial No. 269,416,
vented from escaping from the outer end of the tubeby an inert' plug 9 which is also preferably, formed ofA paraffin and inserted into the end of the, tubel and against'the medicated mass, as shown. The outer or free end 10 of the tube extends some distance beyondthe plug and provides a handle, by which if de.- sired the suppositorymayv be removed. y
The head 5 and the tube are provided with s a thin coating 1l offatty or greasy substance, preferably a composition of beeswax and cocoa butter whtch forms a protective covering for thesuppository and also ya lubricant for facilitating the insertion of the suppository inton therectuin. This coating also prevents irritation of the membrane or parts to which the suppository is appliedand is such lthat it willlquickly inelt'at the temperature of the human body. The coating also serves to stiifen the body ofthe supposi`- tory and to seal its pores against escape of the medicament, and hence facilitates the handling and insertion of the suppOSitory.
The suppository is applied by introducing the same into the rectum until the head 5 passes the sphincter muscle and entersthe colon which will position the lmedicated tubular portioncr body of thefsuppository in the canal in which hemorrhoidal conditions usually exist. When in this position the outer free end of the fabric tube projects from the rectum as shown in Fig. l', while the head 5 prevents thesuppository from slipping out.
The heat from the parts surrounding the inserted suppository melts the coating ll of the tube and thereby opens the poresof said tube. and softensfthe medicated mass permitting the same to ooze through the fabric of the tubeI and onto the hemorrhoids or diseased membranes. The pressure of the sphincter muscle also forces some of the medicament out through the opening 8 in the head 5 for treatment of parts, which are very often diseased by hemorrhoidal conditions. The primary purpose, however, of the opening S is to permit the escape of some of the medicated mass inwardly rather than outwardly should the muscle unduly contract the tubular fabric body.
The remains of the suppository, may be removed by means of the handle or projecting end of the tube or will be automatically removed by the next evacuation or movement of the bowels. It will also be seen that the construction of the suppository is such that it may readily be applied without soiling the hand or clothing, and it is not necessary to touch the rectum with the fingers.
l. A suppository comprising a substantially cone-shaped hollow head open at its inner end and having in its outer end a discharge port, the inner walls of said hollow head being tapered from said inner end toward said discharge port, a fabric tube having one end secured in the inner open end of said head and containing a medicament and a plug in the free end of said tube and against the medicament therein.
2. In a suppository, an insoluble porous flexible tube having a head at one end, means between the ends of said tube closing the latter, and a medicament in the tube between said head and said closing means and adapted to permeate to the exterior of the tube, the free end of the tube beyond said closing means con stituting a withdrawal handle.
3. In a suppository, a porous insoluble tube of Hexible nature, a head on one end of said 1- tube provided with a medicament escape passage, the other end of the tube being closed, and a medicament conlined in said tube, said medicament being adapted to permeate to the exterior of the tube and adapted under excessive external pressure to discharge through said passage of the head.
4L. A structure as speciied in claim 3; together with a soluble lubricating coating closing the pores of said tube and also closing said passage.
5. A suppository comprising a porous fabric tube, a bulbous inert head in which one end of the tube is embedded and secured, a medicament in the tube adapted to permeate to the exterior thereof, a plug in the tube to retain the medicament, said plug being spaced from the outer end of the tube leaving said end free to act as a withdrawal handle, and a soluble stiiening and lubricating coating on the tube and head, said coating sealing the pores of said tube.
In testimony whereof I have hereunto affixed my signature.
