An object of my invention ls -to provide atherapeutic agent embodying improvements over the devices shown in my United States LettersiPatent No. 2,452,813, issued November 2, l948,-' and my copendin'g application,serialNoTefifi ll, filed August 28, 1948. The improvements consist ofanoutwardly-bulged upper section onthe therapeutic agent, which is insertable into a body incision or cavity, and the manner in which this bulged section is reinforced. I

It is proposed n this invention to provide improved form of a therapeutic agent, which may ;,be inserted easily-into av body incision or" cavity for catching any liquid draining therefrom. More specifically described, I propose to provide a flexible bag having an outwardly-bulged upper section that is shaped in such a manner as to facilitate insertion thereof into the body incision or cavity. The bulged section is reinforced to maintain it against collapsing during the insertion of this section.

Other objects and advantages will appear as the specification continues, and the novel features of my invention will be set forth in the claims hereunto appended.

For a better understanding of this invention, reference should be had to the accompanying drawing, forming part of this application, in which:

Figure l is a partial section through the therapeutic agent disclosing it applied in an incision or cavity of the body;

Figure 2 is an enlarged transverse sectional view taken along the line II-II of Figure 1;

Figure 3 is a vertical section through the therapeutic agent in folded position prior to insertion into the incision or cavity; and

Figure 4 is a vertical elevational view of the therapeutic agent in fully extended position.

While I have shown only the preferred form of my invention, it should be understood that various changes, or modifications, may be made within the scope of the annexed claims without departing from the spirit thereof.

In carrying my invention into practice, I provide a flexible bag indicated generally at A, which is made of rubber or latex. This bag is preformed with an outwardly-bulged upper section Al and a lower section A2. It is understood that the entire bag constitutes an impervious Figure 1 illustrates the bulged or designated at B.

construction, the pp r irustoconother cavity in a body Referring to the details of bulged section Al includes an ic'al portion H tapering upwardly and inwardly, and a lower irusto-conical portion 12 tapering downwardly'and inwardly. The walls of these frusto-conical portions define an' obtuse angle at the widest portion' l 4 of the bulged section: These walls are somewhat thicker than the wall of the lower'section A21 The upper'conical portion H is fashioned with a relatively long and gradual taper, thereby permitting this portion to be inserted easily into the incision or cavity ['0 without discomfort to the patient. The tendency ofthe body B is to close. against the bulged section Al. Thus, the part B t of the body adjacent to' the entrance of the incision or cavity coacts with the lower frustoconical portion l2 to retain the bulged portion Al in the incision or cavity.

In order to give the necessary rigidity to the bulged portion Al during its insertion and still allow certain amount of yielding, I provide a plurality of ribs l6 extending lengthwise of the bag on the interior of the latter. These ribs are spaced from one another and extend across the obtuse angle at the widest portion M. The ribs are integral with the walls of the oppositely-tapered portions H and H. The exterior surface of the bag A is smooth.

The lower section A2 is foldable into the interior of the outwardly-bulged upper section Al, as clearly shown in Figure 3. The bag occupies this folded position when it is inserted into the incision or cavity 0. Drainage from the body B enters the open top I! of the bag, causing the thin lower section A2 to distend downwardly and to move outwardly from the bulged section A! into the position disclosed in Figure 1. This view indicates a quantity of drainage liouid l8 in the lower section A2. The lower end of the bag has a closed end l9.

Although the bag has been illustrated as having a cylindrical cross-section, it is obvious that other shapes may be employed. For instance, an elliptical or flattened shape for the upper bulged section would facilitate its insertion into a long narrow incision.

This therapeutic agent occupies only a small space when it is folded. It is especially designed for receiving drainage or excretion from an incision, cavity or any orifice in the human body; for frequent micturition; for catching the discharge of acute venereal infection. It can be used for the female menses, as well as incontinence of urine.

I claim:
