Abstract A surgical drainage appliance adapted to collect body wastes of patients who have had colostomy, ileostomy and ileum bladder operations. The appliance is positively adhered to the skin surrounding the stoma and is adapted to removably hold a disposable waste receptacle having an opening in registration with the stoma. The receptacle may be easily changed without affecting the face plate of the appliance which remains adhered to the patient without the necessity of belts and absorbent pads.

Total Claims: 8
Claim 1
Independent Claim
190 words
A surgical appliance adapted to hold a flexible waste receptacle with its open end in alignment with an abdominal stoma, said appliance comprising: a unitary face plate formed with a central opening and an integral cylindrical projection extending forwardly therefrom in alignment with said central opening and forming a smooth continuous opening completely through said face plate, the external wall of said cylindrical projection being formed with releasable interrupted thread engaging means, the forward rim of said cylindrical projection being substantially planar; a retaining ring having releasable engaging means on its inner surface configured to engage said interrupted thread engaging means on said cylindrical projection, said face plate and retaining ring being engageable and disengageable with a fraction of a revolution of one with respect to the other, said retaining ring having an annular portion projecting radially inwardly on its forward end integrally formed therewith, said annular portion having a substantially planar rearward surface; and a first resilient gasket disposed between said annular portion and said forward rim; said gasket providing a seal between said appliance and said waste receptacle when said respective engaging means are mutually and fully engaged.
Claim 2
Dependent Claim
190 words
A surgical appliance adapted to hold a flexible waste receptacle with its open end in alignment with an abdominal stoma, said appliance comprising: a unitary face plate formed with a central opening and an integral cylindrical projection extending forwardly therefrom in alignment with said central opening and forming a smooth continuous opening completely through said face plate, the external wall of said cylindrical projection being formed with releasable interrupted thread engaging means, the forward rim of said cylindrical projection being substantially planar; a retaining ring having releasable engaging means on its inner surface configured to engage said interrupted thread engaging means on said cylindrical projection, said face plate and retaining ring being engageable and disengageable with a fraction of a revolution of one with respect to the other, said retaining ring having an annular portion projecting radially inwardly on its forward end integrally formed therewith, said annular portion having a substantially planar rearward surface; and a first resilient gasket disposed between said annular portion and said forward rim; said gasket providing a seal between said appliance and said waste receptacle when said respective engaging means are mutually and fully engaged.
