Patent attributes
A disposable cupping tube for collecting fluid from a stoma with a hollow compressible cone seated on a rigid hollow stepped conical frustrum having an upper tier and lower tier. The lower tier having an inner wall sloped at a lower angle than the outside wall to maximize the contact area with the periphery of a stoma when the cone is compressed and the base of the stepped conical frustrum is passed over the stoma and pressed against the peristomal skin. An effective air seal is formed between the contact area and the stoma and between the base of the lower tier with the peristomal skin which is pulled up and around the base by the vacuum. A disc with perforations inserted into the lower tier divides the cupping tube into an upper and lower chamber when present.
