Patent ID: 7635361

Claim:
A multi-purpose, integral one-piece, medical suctioning device, comprising, in combination a) first, second and third longitudinally extending tubular body portions of successively different outer diameters, and defining a single, molded plastic unit which is laterally flexible along its longitudinal length, each body portion comprising a bore, b) said first body portion forming annular barbs outwardly presented to receive connection to plastic tubing, c) said second body portion defining an outer diameter greater than the first and third body portion outer diameters, there being an annular stop ring integral with said second body portion and presented toward said barbs to define a stop surface against which said plastic tubing seats endwise, d) said third body portion being elongated, and tapering away from said second body portion to terminate at a laterally flexible, forward tubular tip, e) there being a finger controlled air inlet defined by a sideward protrusion integral with said second body portion, f) said stop ring openly facing said barbs and protrusions and being substantially inflexible sidewardly radially, said stop ring acting to resist narrowing of said bore formed by the second body portion, proximate said air inlet, in response to first and/or third body portion flexing, g) said second body portion having wall thickness, radially, which is greater than the diameter of the bore within said second body portion, h) and wherein said first, second and third body portions consist of translucent plastic material, i) the stop ring openly facing said barbs and said sideward protrusion and being close to said sideward protrusion and acting to resist narrowing of said body bore formed by the second body portion with which the sideward protrusion is integral in response to lateral flexing of the device, said stop ring located between said sideward protrusion and said barbs, j) the bores, formed by said first, second and third body portions, extending from an outside end of first body portion to an outside end of third body portion and located radially inwardly of said protrusion, all having the same diameter.
