Description:
FIELD OF THE INVENTION

This invention relates generally to body waste receptacles and more particularly concerns a novel surgical drainage appliance for colostomies, ileostomies, and the like.

DISCUSSION OF THE PRIOR ART

Prior surgical drainage appliances have provided means for holding an opening of a flexible bag over the incision or stoma of a colostomy patient, for example, but these devices have generally failed to meet one or more of the requirements necessary to provide an effective appliance capable of being satisfactorily and comfortably worn for substantial periods of time. Many of the prior devices, while generally satisfactory, do on occasion allow the waste material to leak outside of the receptacle. Also some of the prior devices, while having disposable receptacles, are not easily changeable in a sanitary manner and without contaminating the surrounding area.

SUMMARY OF THE INVENTION

It is the primary object of this invention to provide a surgical drainage applicance which is fully satisfactory for use by patients who have had colostomy, ileostomy or ileum bladder operations and which effectively eliminates the possibility of leakage while the device is being worn. At the same time the appliance provides a disposable receptacle which is readily changeable under relatively sanitary conditions. This device is very versatile and may be applied immediately after the operation which necessitated the use of such a device.

This novel drainage appliance is extremely compact and simple, primarily comprising a face plate and a clamping ring, and is used together with a disposable thin flexible bag receptacle. The bag may be separate or it may be integral with the clamping ring. It should be noted that a belt is not required because the appliance is positively adhered to the patient with the result that the device is extremely easy to use, while the chances of malfunctions are substantially reduced. There may be cases where a patient would prefer to wear a belt to help hold the device in place and provisions may easily be made for its use.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring now to the drawing, there is shown a surgical drainage appliance 11 comprising a face plate 12 having a central cylindrical projection 18 with an opening 19, a cylindrical retaining ring 13, a flexible bag receptacle 14 and a resilient gasket 15. Retaining ring 13 is provided with a plurality of interior projections 16 which are intended to mate with non-continuous, notched threads 17 on the cylindrical projection 18 of face plate 12. The projections 16 and threads 17 are shown constructed so that only a partial turn is necessary to go from full engagement to full disengagement of the retaining ring on the mounting cylinder. As little as one-eighth turn may be sufficient to fully lock the retaining ring in place. It is possible that a locking device other than threads may be used which provide a positive but easily releasable connection. When locked in place, annular portion 21 of retaining ring 13 is sealed to rim 22 of cylindrical projection 18 by means of resilient gasket 15. Bag receptacle 14 is tightly sealed to the appliance 11 by inserting its open top through the opening 23 in retaining ring 13 a sufficient distance so that the edge of the bag opening extends entirely through the retaining ring. The combination bag and retaining ring is then engaged with cylindrical projection 18 so that gasket 15 is held between annulus 21 and rim 22 with the edge of the bag firmly held between gasket 15 and rim 22. A partial turn of clamping ring 13 then locks and seals the bag, clamping ring and face plate together. The resiliency of gasket 15 permits projections 16 to engage the notches 17a in threads 17 while still maintaining a tight connection between the bag and the appliance. It is evident that the edge of bag 14 around its access opening is between the outside of cylindrical projection 18 and the inside of retaining ring 13 and is sealed with respect to face plate 12 by gasket 15 bearing upon rim 22.

Flat surface 25 of face plate 12 is normally coated with a pressure sensitive adhesive 26. After the skin 27 around the stoma 31 (see FIG. 2) has been properly conditioned, the face plate is pressed against the skin to form a tight wrinkle-free seal therewith. The plate may be adhered to the user either before or after the bag has been attached thereto. In order to further ensure against possible dislocation of the face plate by being caught on external objects, tape strips 32 may be placed across the elongated portions of the plate overlapping onto the skin of the wearer. Such tape strips are not absolutely necessary and may be omitted if desired. Alternatively, with reference to FIG. 6, belt 33 having securing elements 34 may be used to give the wearer a greater feeling of security. Face plate 12 is then modified by the addition of pins 35 having enlarged heads. Securing elements 34 on either end of belt 33 are formed with slotted openings 36 which readily engage pins 35 as show. Other simple attaching means may be used to secure the belt to the face plate.

This appliance as described above provides a positive, secure, leak-proof connection between the bag receptacle and the stoma of the user without the need for bacteria-breeding absorbent pads and uncomfortable belts or harness arrangements. When it is desired to change the bag receptacle, the face plate remains in place on the user and only the retaining ring is loosened, allowing the bag to be easily removed and thrown away. It should be noted that the retaining ring and that portion of the edges of the bag between gasket 15 and the patient are uncontaminated by the waste material and do not become contaminated when the bag is changed. Thus, a used bag receptacle may be exchanged for a fresh sterilized receptacle in a few seconds without the need for removal of the face plate and extensive cleaning of the appliance and the surrounding area. The invention does not necessarily include the bag receptacle since such bags are replaceable and to a large extent interchangeable.

The face plate and retaining ring are preferably made of a semi-rigid plastic or rubber which are very light and do not contribute to the discomfort of the wearer. The materials of the retaining ring and face plate may even be made sufficiently flexible so that a resilient gasket is unnecessary. However, where it is desired to use gasket 15, it may be secured to the inner side of rim 21 if desired so that there is no danger of its becoming lost when the receptacle is changed.

In order to prevent possible abrasion of the skin around the stoma of the wearer, it is necessary to properly condition the skin and to use the proper pressure sensitive adhesive on the face plate. It has been found that surface 25 of the face plate may be coated with a silicon spray adhesive as an anchor base for a surgical semi-viscous adhesive compound which is then spread evenly across surface 25 over the silicon spray adhesive. Similarly, the skin around the stoma is coated with a conditioning substance such as a compound of benzoine tincture and then the surgical semi-viscous adhesive is spread on the skin. After a few minutes, the adhesives are properly conditioned so that the face plate may be pressed in place with the opening through the plate aligned with the stoma of the user. If desired, the adhesive may be applied to either the face plate or the patient, rather than to both. In any event, the adhesive has the characteristic of remaining flexible so that plate 12 may be easily peeled off in the manner of adhesive tape. This invention is so constructed that the face plate need not be removed for purposes of cleaning the stoma and the skin immediately surrounding the opening, together with opening 19 in cylindrical projection 18.

A feature of the invention is that cylindrical projection 18 protects the stoma from contact with and possible injury from foreign materials such as various articles of clothing. Another feature is that the appliance has such universal use and versatility in its field that it is readily adaptable to be made in various sizes for pediatric as well as adult users.

An alternative embodiment of the invention is shown in FIG. 5. In this preferred embodiment, face plate 12 with cylindrical projection 18 and interrupted bayonet type locking thread means 17 are substantially the same as the embodiment of FIGS. 2-4. Likewise retaining ring 13, gasket 15 and receptacle 14 are also substantially the same as those previously shown. However, in this structure, receptacle 14 does not extend through ring 13 and around cylinder 18 but is fused to ring 13 as shown. Thus the retaining ring and the receptacle 14 are formed as a unitary structure which is removably securable to face plate 12. The appropriate positive seal is provided by gasket 15 as before. Alternatively, an additional seal may be provided by a second gasket 37 located at the base of cylinder 18.

Manipulation and use of this embodiment is even easier than that previously described. The bag and retaining ring, being unitary, are attached and discarded together. Securing to the abdomen of the user is exactly the same as for the other embodiment. However, if it should happen that a change is needed but the wearer has no ring/receptacle available, it is possible to separate the used receptacle from the ring and use any available plastic bag in the manner shown in FIGS. 2-4. This usage is available because the basic elements of the FIG. 5 embodiment are the same as the previously described embodiment.

In view of the foregoing, it is evident that many other modifications will occur to those skilled in the art which are within the scope of this invention. For example, the flat surface 25 of face plate 12 may be slightly concave to fit the contour of the wearer's abdomen. The appliance may be made of many different and economical materials having varying characteristics of flexibility. The bag receptacle may be made of many different materials and have various shapes and sizes to suit its particular use.
