  • Hydrocolloid containing liquid carrier for a diagnostic or therapeutic agent
    Patent number: 3984571
    Abstract: On contacting a moist aqueous surface, a fine particle size hydrocolloid suspended in a non-aqueous water-immiscible mobile liquid attaches itself through rapid hydration to the moist surface. Drainage of the mobile liquid leaves a coating of the particles of the hydrocolloid on the surface. If a radiopaque agent or a medicinal agent is co-suspended with the hydrocolloid, a uniform thin layer of the agent will be carried by the particles of hydrated hydrocolloid onto the moist surface.
