Medical diagnostic cart and method of use
First Claim
1. A medical diagnostic cart apparatus comprising:
- a fixture mounted on a mobile cart, the fixture having an inspiratory conduit joined with an expiratory conduit, the conduits further joined with a patient interface;
an air inlet, and an inlet valve interconnected in series by the inspiratory conduit; and
a manometer interconnected with the inspiratory conduit between the inlet valve and the patient interface;
an air outlet, a spirometer, and an outlet valve interconnected in series by the expiratory conduit; and
a capnometer interconnected with the expiratory conduit between the outlet valve and the patient interface;
the inlet valve and the outlet valve each having construction enabling air flow in only one direction therethrough, the inlet valve oriented in the inspiratory conduit for enabling air flow to only pass toward the patient interface, the output valve oriented in the expiratory conduit for enabling air flow to only pass toward the air outlet;
the inlet valve further having a shutoff, the shutoff, when actuated, preventing air flow through the inlet valve.

Abstract
A medical diagnostic tool provides a fixture mounted on a cart, the fixture having an inspiratory conduit joined with an expiratory conduit, with both joined to a patient interface. An air inlet, and an inlet valve are interconnected in series by the inspiratory conduit; and a manometer is interconnected with the inspiratory conduit between the inlet valve and the patient interface. An air outlet, a spirometer, and an outlet valve are interconnected in series by the expiratory conduit, and a side-stream capnometer is interconnected with the expiratory conduit between the outlet valve and the patient interface. The inlet valve and the outlet valve each enable air flow in only one direction. The inlet valve further provides a shutoff, which when activated, prevents air flow through the inlet valve.

10. A medical diagnostic method comprising the steps of:
-
a) providing a fixture having an inspiratory conduit joined with an expiratory conduit, both further joined with a patient interface; b) interconnecting an air inlet, and a one-way flow inlet shutoff valve in series in the inspiratory conduit; and
connecting a manometer with the inspiratory conduit between the inlet valve and the patient interface;c) interconnecting an air outlet, a spirometer, and a one-way flow outlet valve in series in the expiratory conduit; and
connecting a capnometer with the expiratory conduit between the outlet valve and the patient interface;d) interconnecting the patient interface with a patient; e) recording tidal volume of each single patient breath when breathing normally, and average tidal volume for a single patient breath when breathing normally over a measured time period using the spirometer, with the inlet shutoff valve open; f) recording respiration rate, pulse rate and end tidal CO2 level using the capnometer, with the inlet shutoff valve open; g) recording maximum patient suction using the manometer, with the inlet shutoff valve closed; and h) recording vital capacity using the spirometer. - View Dependent Claims (11, 12)
