DRAINING DEVICE.

Appneanon filed April 27, 1925.

This invention relates to draining devices, particularly adapted for use by surgeons in draining bladders and similar sacs of the body after surgical operations, and has for its object the production of an inflatable tube adapte-d to be placed upon a catheter and inserted into an incision and then inflated until the wall of said tube is forced into intimate contact with the wall of said incision and IU thereby prevent any discharge from the sac except that which passes through the catheter.

This object is attained by the device illustrated in the accompanying drawings.

la For the purpose of illustrating the invention, one preferred form thereof is illustrated in the drawings, this form having been found to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which the invention consists can be variously arranged and organized, and the. invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described except as required by the scope of the appended claims.

Of the drawings:

Figure 1 represents an elevation of a device embodying the principles of the present invention.

Figure 2 represents a longitudinal section of same mounted upon a catheter and before inflation, and l Figure 3 represents a longitudinal section of the device inserted into an incision and inflated, the catheter on which it is mounted being shown in elevation.

Similar char-acters indicate like parts throughout the several figures of the draw` ings.

In the drawings is a catheter which may be of any usual construction and on which the device embodying the present invention is adapted to be mounted intermediate its ends.

This device consists of aninflatable tube 11 having twostretchable necks 12, 13 preferably disposed at the opposite ends thereof as shown in the drawings.

Near theneck 13 thetube 11 has extending therefrom a pipe 14 through the bore of which air or liquid is adapted to be forced in order to infiate the tube.

Thenecks 12, 13 are made of considerthan the diameter of the Serial No. 26,054.

catheter on which thetube 11 is to be mounted.

When thetube 11 is to be used thenecks 12, 13 are stretched in any well known manner to permit the insertion therethrough of thecatheter 10.

Thesenecks 12, 13 when on the catheter will bind upon the outer wall of the catheter sufiiciently to prevent the escape of any of the contents of thetube 11.

lt is preferable, however, in mounting the tube 1l upon thecatheter 10 to turn thesenecks 12, 13 inwardly into thetube 11 as indicated in Fig. 2.

By so doing it is obvious that the pressure upon these inturned necks when thetube 11 is inflated will more securely bind the necks upon the catheter and thereby more effectuallg] prevent leakage of the contents of the tu e.

The ends of thenecks 12, 13 are provided with thebeads 15 to strengthen these necks at this point and for a similar reason the outer end of the laterally4 extending pipe 14 is provided with a bead 16.

As shown in the drawings thecatheter 10, for convenience, is provided with a perforated bulb 17 for insertion into the sac to be drained while the outer end of the catlieter is preferably provided with a bead 18 to facilitate in retaining thereon a flexible tubing' through which the contents of the sac .may be drained into some form of receptacle.

After a surgical operation has been performed it is quite necessary in many cases to artificially drain a bladder, sac, or canal, and this is done by a catheter or similar tubular member.

This catheter, however, never lits the incision or mouth of the sac and as a consequence much of the contents of the sac leaks therefrom outside of the cat-heter and spreads over the body of the patient, making it necessary to cover the body with Sponges made of absorbent gauze to care for all discharge not passing through the bore of the catheter.

On account of this leakage the patient must lie upon a rubber blanket which in itself is very objectionable, but the greatest disadvantage is the fact that moistened condition of the body often causes bed sores.

The present invention is designed to obviate these and other difficulties attending the methods heretofore in use.

lll)

The manner in which the device is used is as follows. A

Thetube 11 having been mounted upon some form of catheter as shown in Fig'. 2 is inserted into an incision in the body as indicated in dotted lines at 19.

The pipe 14 is then connected to a syringe or similar device by which air or liquid may be forced into thetube 11 to stretch and inflate it as shown in Fig. 3.

The flexible discharge tubing is secured to the other end 18 of the catheter.

As soon as thetube 11 has been inliated the pipe 1li is closed in some manner so that the contents of thetube 11 cannot escape.

Both thetube 11 and pipe 14Y are made of very thin material and the simplest Way of closing the pipe 14T after the inflation has been completed is by twisting the pipe 14, Wrapping it around the protruding end of the catheter and then placing thereon a rubber band Q0.

`This having been done there is no escape for the contents of thetube 11 and portions thereof 21 will be forced into such intimate contact with the Wall of theincision 19 that there can be absolutely no leakage from the sac, the thin material of the tube being' forced into every irregularity in the Wall of the incision.

For the inflation of thetube 11 air will be used generally, but it is quite obvious that in some cases and under some conditions it may be desirable to use a liquid uuder varying degrees of temperature.

Vhen this device is in use the patient is kept perfectly clean and free from all moisture due to leakage of the contents of the particular sac being drained.

The shape of themember 11 may be varied to suit dierent conditions.

It is believed that the operation and many7 advantages of the invention will be understood Without further description.

Having thus described my invent-ion, .l claim- 1. The combination of a catheter for draining a sac through an incision an inflatable tube for enclosing the catheter intermc` diate its ends said tube being adapted to e2;- tend beyond the opposite ends of said incision; and means for iniiating the tube to cause its outer Wall to bear against the wall of the incision and the adjacent outer and inner Walls of the portion of the body in Which the incision has been made.

2. rThe combination of a catheter for draining a sac through an incision; an iuflatable device for closing the incision adapted to be disposed upon said catheter and provided with a lateral. liexible pipo extending laterally from the Wall thereof ud through which the device may be inflated and pressed against the Wall of said incision throughout its entire length and the surfaces adjacent the opposite ends thereof.

3. The rcombination of a catheter for draining a sac through an incision; an inflatable member' for closing the incision having at its opposite ends inturned stretchable necks surrounding and gripping said cathe ter; a flexible pipe near one end of said member providing means for inflation and adapted to be Wound about the outer end of the catheter; and means for retaining` the Wrapped portion of the pipe upon said outer end.

t. The combination of a catheter for draining a sac through an incision; an inflatable member for closing the incision hav ing at its opposite ends inturned stretchable necks surrounding and gripping said catheter; a flexible pipe near one end of said member providing means for inflation and adapted to be Wound about the outer end of the catheter; and an elastic band for retaining the Wrapped portion of the pipe upon said outer end.
