Abstract
Abstract A one-piece sealed disposable enema unit with a lubricated rectal tip is disclosed. The rectal tip of the unit is sealed with a break-off tab. Attached to the tab is a sleeve which covers the exterior of the rectal tip and prevents contamination of the lubricant. Before use, the break-off tab must be twisted off and the tab with the attached sleeve removed. Therefore, the unit is tamper proof and security of the contents is insured.
