Claims. (Cl. 128-283) This invention concerns a new and improved surgical drainage device for colostomies, ileostomies, and the like.

According to the invention there is provided a drainage appliance including a rigid ring adapted to secure thereon a resilient flanged disc. The ring is so arranged that it also supports and locks in a hermetic leakproof union a pouch or bag through which a stoma or other body opening drains. The flanged disc maintains a comfortable, leakproof engagement with the body of the wearer of the appliance. The ring may be provided with a belt to support the appliance on the wearers body. The ring is arranged so that the flanged disc is retained in detachable engagement so that the disc can be replaced by others of different shapes, sizes, apertures openings, resil' iences, etc. The pouch may be made of plastic and is readily detachable from the ring and disc.

It is therefore a principal object of the invention to provide a surgical drainage appliance including an improved ring holder for a pad and pouch.

A further object is to provide a surgical drainage appliance including a flanged, resilient pad, a collapsible, disposable pouch, and a ring adapted to removably secure the pad and pouch together in a leakproof union.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. l is a front elevational view of an appliance embodying the invention.

Fig. 2 is a vertical sectional view taken on an enlarged scale on lines 22 of Fig. 1, showing the appliance applied to a patients body.

Fig. 3 is a perspective view of a resilient disc or pad employ-able in the appliance.

Fig. 4 is a perspective front view of a ring according to the invention.

Fig. 5 is a perspective rear view of the ring.

Figs. 6 and 7 are front and rear elevational views, respectively, of the ring, the strap being omitted in Fig. 7.

Figs. 8 and 9 are front and rear elevational views, respectively, of another form of ring according to the invention.

Referring to Figs. 1-7, there is shown a circular ring 10 having a cylindrical Wall 12. Extending inwardly radially from opposite ends of the wall 12 are two annular flanges 14 and 16 disposed parallel to each other to define a channel 15 therebetween. Extending radially inwardly from the flange 16 is a frusto-conical flange portion 18 directed obliquely toward flange 14. The ring may be formed of metal, plastic, pressed fiber, or other composition material to impart required rigidity.

A flanged pad or disc 20 (see Figs. 2 and 3) is detachably secured to the ring. This pad is preferably a resilient member made of rubber, foam plastic, cellulose composition, and the like. It may be formulated with antibacterial agents, germicides, deodorants or other medicinal compounds. The outer annular side 22 may be coated with a pressure sensitive adhesive 24- for adher-' ing the disc removably to the body wall 26 of a patient. The pad has a central opening 28 larger than the stoma 30 constituting the colostomy or other draining opening in the patients body. The opening 30 is substantially concentric within the opening 28 and the pad 20 yields and conforms to the contour of the body wall so that a leakproof contact is had therewith around the opening 30 as shown in Fig. 2. A groove 32 is formed around the outer cylindrical wall 33 of the disk into which fits the annular flange 14 of ring 10. The flange 14 thus fits snugly between two annular flanges 34, 36 formed at the periphery of the pad and separated by groove 32,'while flange 36 fits snugly in channel 15.

A flexible bag 38 of plastic such as polyethylene, of rubber, or other moistureproof material is removably secured to the ring and pad. The open mouth at the upper end of the bag has reversed folds 44, 46 engaged as clearly shown in Fig. 2 over and around flange 36 in channel 15. Folds 46, 48 are engaged around flange 14 in groove 32 to abut the inner wall 42 of flange 34 forming the rear annular Wall of groove 32. Flange 14 thus fits between the reversely folded bag end portions 46,

43 in the groove 32. The mouth of the bag also has reversely folded portions 44, 50 passing around both sides of flange portion 18 with a portion of fold 44 engaged between a frusto-conical wall portion 52 of front side 54 of the pad and the inner side of flange portion 18. The mouth of the bag thus has three successive reversely folded portions around flange portion 18, around flange 36 and around flange 14, respectively. This triple reverse folding of the mouth of the bag provides an engagement which is leakproof for solids, liquids and gases and can support the bag and its contents.

After discharge of any material into the bag, the flange 36 can be manually disengaged from the channel 15 between flanges 14 and 16 to release the bag. The bag can then be emptied of its contents and discarded, or washed and reused if desired.

A strap 53 can be secured by screws or rivets 57 in holes 59 to the outer side of flange 16 of the ring. Alternatively, the ring can be provided with hooks or loops for engaging sections 61, 63 of a strap as indicated in Fig. 6. The strap will encircle the body and help support the appliance on the body Wall 26.

If desired, perforations 62 may be provided in the pad around opening 28 for relieving and passing perspiration from the body Wall 26 abutted by the pad into the bag, as shown in Fig. 2, to increase comfort for the patient wearing the appliance.

The pad, ring and bag assembly provides a compact drainage device which can be worn inconspicuously under clothing. The plastic bag 38 cannot be removed from the disc while the appliance is being worn :since the pressure of the body of the patient holds the rubber disc firmly on the flange holder which in turn holds the plastic bag. Furthermore, the plastic bag may have an openable bottom. Instead of forming the pad and ring in circular outline, they can be formed substantially oval as shown by ring 10 in Figs. 8 and 9. Parts corresponding to those of ring 10 are shown by primed numbers such as flanges 14', 16', 18 and hooks 55.

The pad, ring and bag assembly is readily detached from the body of the patient for disassembly and cleaning, and to change the pad or bag from another of different shape and size as desired. The pad can be cast or molded and the ring can be formed as a stamping,

0 casting or molding by well-known metal and plastic fabembodiments of my invention, it is to be understood that I. do not limit myself to the precise constructions herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claims.
