A connector for a respirator apparatus which is adapted to be inserted into the open stem of a respiratory Y-tube and connected to an endotracheal tube is provided. In one embodiment the connector is adapted to be used as a pressure measuring or gas sampling device and in another embodiment as a pneumotach for measuring the respiratory flow rate of a patient. The dead space commonly encoutered in prior art connectors is substantially reduced and the likelihood of disconnection is reduced or eliminated. The connector permits gas measurement adjacent the patient and at a cross sectional flow are that approximate the inner diameter of the endotracheal tube.

A connector for attaching a Y-tube of a ventilator to an endotracheal tube and for connection to a measuring instrument wherein the Y-tube has a stem from which two branched arm extend, comprising: a generally hollow cup member having a wall closing one end and an open end opposite the wall; said cup member having an outer circumference adapted for sealing contact with the Y-tube stem, with the closed end of the cup inserted into the stem; a flange element, having an opening on its peripheral surface, extending outwardly and laterally about the edge of the open end of the cup member and integral therewith; a tubular conduit connected to the wall and extending along the axis of the cup and protruding from the open end, said conduit having opposed open ends so that gas may flow past the wall through the conduit, said conduit having an inner diameter that approximates the inner diameter of the endotracheal tube and an outer diameter that is adapted for connection to the endotracheal tube, the tubular conduit having a port through its side wall opening on its inner diameter between the open ends; a pair of support members integrally connected to the interior of the cup member and extending to opposite sides of the tubular conduit, respectively, throughout a substantial length of the cup member; a passage extending from the exterior opening in the flange, through the flange and cup member, and along the inside of one of the support members to terminate with the port opening in the tubular conduit to provide a narrow channel through which gases flowing through the tubular conduit may be withdrawn from the conduit, and means for connecting to the flange member opening to permit passage of the gases drawn from the tubular conduit.
