PATIENT WYE WITH FLOW TRANSDUCER
First Claim
1. A patient wye, comprising:
- an inspiratory port;
an expiratory port; and
a patient port, wherein the inspiratory port, the expiratory port and the patient port are in fluid communication with one another;
an inspiratory branch extending between a center point of the patient wye to the inspiratory port;
an expiratory branch extending between the center point of the patient wye and the expiratory port;
a patient branch extending between the center point of the patient wye and the patient port;
a first flow transducer located within a first branch of the patient wye, wherein the first selected branch is a first one of;
a) the inspiratory branch;
b) the expiratory branch;
orc) the patient branch.

Abstract
A patient wye for use in connection with a ventilator having one or more integrated transducers is provided. A transducer is integrated into the patient wye by locating the transducer within a branch of the patient wye. A transducer can be located between the center point of the wye and the port of the branch with which it is associated. More particularly, the transducer can be located so that it is on a side of a wall defining the branch in which it is placed that is opposite a connection surface for attaching tubing associated with a corresponding limb of the ventilator to the patient wye. Accordingly, flow or other transducers can be added to a patient circuit without necessarily increasing the volume of the patient circuit.
