1. A stopcock, comprising:
- an elongated body member defined by a substantially cylindrical body portion and a tapering body portion, said cylindrical body portion having a round opening on one side extending into a cylindrical cavity;
a first tapering tubing connection extending from said tapering body portion, said tapering tubing connection having a first fluid passageway extending therethrough and into said cylindrical cavity;
a second tapering tubing connection extending from said cylindrical body portion of said elongated body member in a direction substantially opposite to said first tapering tubing connection, said second tapering tubing connection having a second fluid passageway extending therethrough and into said cylindrical cavity of said elongated body member, said second fluid passageway is substantially aligned with said first fluid passageway in said first tapering tubing connection;
a syringe port extending from said cylindrical body portion of said elongated body member and positioned between said first tapering tubing connection and said second tapering tubing connection, said syringe port having a third fluid passageway extending therethrough and into said cylindrical cavity of said elongated body member, said third fluid passageway positioned approximately 90 degrees relative to both said first and second fluid passageways; and
a key member defined by a cylindrical body portion and a handle, said cylindrical body portion is disposed within said cylindrical cavity of said elongated body member when said stopcock device is assembled, said cylindrical body portion having a T-shaped fluid passageway extending therethrough in a plane of rotation of said key member, said T-shaped passageway through said cylindrical body portion selectively cooperating with said first, second and third fluid passageways for different modes of operation, said cylindrical body portion having an outer surface provided with a circumferential ridge aligned and fluidly sealing with said circumferential groove in the surface of said cylindrical cavity in said elongated body member.

Abstract
A gastric adapter comprising a three-way stopcock. The stopcock includes connectors having tapered surfaces for sealing tightly with the ends of nasogastric, gastrostomy and feeding tubing and includes fluid passageways of sufficient diameter so as to be capable of conveying viscous fluids such as emulsion, suspensions and slurrys to provide effective operation and use in the particular environment of administering critical fluids and medications through nasogastric and gastrostomy tubing.
